Humidifier

This application claims the benefit under 35 U.S.C. § 119 (e) of U.S. Provisional Patent Application Ser. No. 63/637,271, filed on Apr. 22, 2024, titled “HUMIDIFIER,” the entire contents of which are incorporated by reference herein.

The invention relates to a humidifier, and particularly, a humidifier incorporating an integrated mist illumination chamber that produces visually aesthetic flame-like or lantern-like lighting effects in addition to functional humidity dispersion.

Conventional humidifiers are primarily designed to increase humidity levels in indoor environments to improve comfort, prevent dryness, and support health and wellness. These devices typically function by dispersing water vapor or mist into the surrounding air. However, traditional humidifiers are generally utilitarian in appearance and operation, offering little or no aesthetic value beyond their basic humidification function.

Various improvements have been proposed in the art to enhance the user experience with humidifiers, such as introducing aromatherapy features, sound generators, or color-changing lights. Nevertheless, these enhancements have often been limited to superficial add-ons, lacking meaningful integration between humidification, lighting, and aesthetic output. In many existing products, light sources are merely appended to the humidifier body without interacting meaningfully with the generated mist or the humidification process itself. As a result, these devices fail to achieve a cohesive or transformative ambient effect.

Furthermore, in conventional systems, mist emission is often turbulent, uncontrolled, and opaque to illumination, making it difficult to create visually striking mist displays. Existing devices that attempt to backlight or illuminate mist often suffer from poor light-mist interaction, with mist scattering light inefficiently and producing hazy or muddy visuals rather than defined, flame-like or lantern-like effects. Additionally, many humidifiers operate without sufficient safety mechanisms, such that accidental operation without water, improper tank seating, or exposure of sensitive electronics to moisture can lead to device failure or hazards.

There is a clear and unmet need for humidification devices that seamlessly integrate functional mist generation with dynamically illuminated mist presentation to produce ambient visual experiences that rival or enhance conventional lighting fixtures or decorative objects. There is a further need for such devices to incorporate intelligent sensing, fluid control, and modular design elements to ensure safe operation, ease of maintenance, aesthetic adaptability, and compatibility with modern smart home environments.

Accordingly, the present invention addresses these shortcomings by providing a portable, free-standing humidifier that incorporates a lighting and misting chamber, wherein fine mist generated by a transducer is illuminated within a specially designed transparent or translucent chamber to produce a flame-like or lantern-like visual effect. The invention further incorporates a mist tube to concentrate and guide mist flow, multiple strategically positioned light sources for optimized illumination dynamics, dual blower systems for enhanced mist propulsion, magnetic sensing mechanisms for safe operation, and intelligent controllers for user customization and smart system integration.

By combining functional humidification with compelling ambient lighting, the invention transcends traditional humidifier designs and creates an entirely new product category at the intersection of wellness technology, ambient lighting, and smart home integration.

The present invention relates to humidifiers that not only generate and disperse mist for functional humidification but also provide an enhanced visual aesthetic by illuminating the mist within a specialized chamber. The humidifier generally includes a tank configured to hold a fluid, a base configured to support the tank, a mist generator positioned within the base and configured to generate mist from the fluid, and a chamber positioned within the tank. The chamber includes a mist inlet in fluid communication with the mist generator and a mist outlet through which mist is expelled into the ambient environment.

At least one light source is positioned relative to the chamber and is configured to emit light into the chamber such that mist traveling through the chamber is illuminated, creating a visually appealing flame-like or lantern-like effect. At least one blower positioned within the base is configured to propel the mist generated by the mist generator upwardly through the chamber toward the mist outlet.

In some examples, the mist generator may comprise a transducer, and multiple light sources may be positioned around the transducer to enhance the uniformity and intensity of the lighting effect. In certain embodiments, the fluid contained within the tank surrounds at least a portion of the external surface of the chamber, further enhancing the visual depth and glow of the illuminated mist column.

To promote operational safety, the humidifier may also include a magnetic sensing mechanism configured to detect whether the tank is properly seated on the base, and to prevent operation of the mist generator and blower when the tank is improperly installed. In some implementations, two blowers may operate in tandem to increase mist velocity and enhance the visual turbulence of the illuminated mist.

The chamber may be at least semi-transparent or translucent, allowing for controlled diffusion and refraction of light. In further examples, the chamber may extend between the light source and the mist outlet of the tank, forming a dedicated illuminated mist pathway. The humidifier may also include a mist tube positioned within the chamber to concentrate mist flow, and the light source may be configured to emit light within the interior of the mist tube, the chamber, or both.

In another example, the chamber may extend from a bottom side of the tank and project upward toward the mist outlet at the top side of the tank. The bottom of the tank may include a valve assembly to regulate fluid delivery to the mist generator, and may also include a blower cover to protect internal components. The chamber itself may be formed as a cylindrical tube or other shape suitable for optimizing mist flow and light distribution.

Other devices, apparatus, systems, methods, features and advantages of the invention are or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, within the scope of the invention, and be protected by the accompanying claims.

In this disclosure, all “aspects,” “examples,” “embodiments,” and “implementations” described are considered to be non-limiting and non-exclusive. Accordingly, the fact that a specific “aspect,” “example,” “embodiment,” or “implementation” is explicitly described herein does not exclude other “aspects,” “examples,” “embodiments,” and “implementations” from the scope of the present disclosure even if not explicitly described. In this disclosure, the terms “aspect,” “example,” “embodiment,” and “implementation” are used interchangeably, i.e., are considered to have interchangeable meanings. The inclusion of alternative embodiments also highlights the flexibility and adaptability of the invention across multiple product designs, configurations, and user needs.

In this application, the term “substantially,” “approximately,” or “about,” when modifying a specified numerical value, may be taken to encompass a range of values that include +/−10% of such numerical value. Further, such as “communicate,” and “in . . . communication with,” or “interfaces” or “interfaces with” (for example, a first component “communicates with” or “is in communication with” a second component) are used herein to indicate a structural, functional, mechanical, electrical, signal, optical, magnetic, electromagnetic, ionic or fluidic relationship between two or more components or elements. As such, the fact that one component is said to communicate or interface with a second component is not intended to exclude the possibility that additional components may be present between, and/or operatively associated or engaged with, the first and second components. Such broad definition ensures that the invention encompasses a variety of configurations, including both direct and indirect communication between parts.

For purposes of reference and description, the humidifier,of the present invention is considered to have horizontal (x-axis) and vertical device axis (y-axis) and a z-axis, as shown inalong which the components of the humidifier are positioned relative to each other. Terms such as “axial” and “axially” are assumed to refer to the respective axis or any direction or axis parallel to the device axis, unless indicated otherwise or the context dictates otherwise. For convenience, movement relative to a device axis may alternatively encompass movement relative to an axis that is parallel to the device axis that is specifically illustrated in, unless the context dictates otherwise. Thus, linear translation “along the device axis z” is not limited to translation directly on (coincident with) the device axis, but also encompasses translation parallel to the device axis z, depending on the context. Similarly, rotation “about the device axis y” also encompasses rotation about an axis that is parallel to the device axis y, depending on the context.

Further, the humidifier,of the present invention is considered to have a height (h), length (l) and width (w), as also shown in. These dimensional descriptors assist in defining proportionality and arrangement of internal and external components to optimize both functionality and aesthetic presentation.

As illustrated and discussed in the following figures, examples of a humidifier,is provided. In the example, the humidifier,is a portable, free-standing humidifier. “Portable” being defined as having the ability to be carried or moved with ease. “Free standing” being defined as having the ability to remain stable and upright without external restraints. It should further be understood that the term “humidifier” may interchangeably used with the terms “mist generator” or any term that refers to an apparatus that in general, draws a liquid from a tank or source and disperses it into the air in the form of mist, vapor, and/or steam. The inventive humidifier not only performs the functional task of humidification but also serves as a visually impactful decorative object, capable of enhancing the atmosphere of indoor spaces.

As will be illustrated and discussed below, in the examples of the humidifier,of the present invention, the humidifier,is a portable ultrasonic humidifier that incorporates a lighting assembly,that comprises a chamber,that is illuminated by at least one light source,to create a flickering flame or lantern effect. This integration of mist generation and illumination within a translucent or at least semi-transparent chamber establishes not only a functional benefit of humidification but also a sensory-enhancing visual spectacle, offering users a multi-sensory experience that transcends typical humidifier designs. The simulated flame effect adds a dynamic, soothing aesthetic that can complement the ambiance of residential, commercial, or hospitality environments, thereby expanding the utility and appeal of the device beyond its primary humidification function.

is a top perspective view of one example of an implementation of a humidifierof the present invention. In general, humidifiercomprises of tank assemblysupported by or removably seated above base assembly. The tank assemblycomprises of a tankfor holding a liquid (e.g., water) to be humidified and mist outletpositioned on top side of tank. Optionally, humidifiermay also include shellfor covering tank. Shellmay be structured as a sleeve and may include at least one or more decorative elementsfor not only enhancing the aesthetic appeal of humidifierbut also to enhance the flickering flame or lantern effect of lighting assembly. Decorative elementsmay take the form of cutouts, engravings, or patterns that selectively diffuse or refract the light passing through the shell, intensifying the perception of movement and depth in the illuminated mist, thereby creating an even more captivating visual phenomenon. In other examples, decorative elementsmay also or alternatively be included on tankand/or chamber.

Further, optionally, humidifiermay also include at least one handleattached to tank assembly, namely tankfor allowing a user to hold or carry humidifier. Handlemay attach to tank assembly by attachment elements,. While the attachment elements,are shown to be thumb screws, it should be understood that any attachment mechanism known in the art may be utilized, including but not limited to hook and loop fasteners (e.g., Velcro), friction fit, magnetic attachments, press studs, clips, or snap-fit connectors.

is a bottom perspective view of humidifier.illustrates base assemblycomprising a bottom side, plate or cover, one or more vent openingsfor venting heat from blowerand/or transducerand one or more feetfor supporting base assemblyover a surface. As stated above, humidifieris configured as a portable, free-standing humidifier. The base assemblyincludes a bottom plate or coverthat encloses and protects the underside of the base assembly. One or more vent openingsare formed through the bottom plate, allowing for the venting of heat generated by internal components, such as the blowerand transducer, during operation. Proper heat dissipation through vent openingsprevents thermal stress, enhances operational safety, and prolongs the lifespan of sensitive electronic and mechanical components housed within base assembly. The vent openingsensure that excessive heat does not build up within the base assembly, thereby improving device safety and extending component lifespan. Further, base assemblyis supported by one or more feetthat project from bottom plate. The feetare configured to maintain the base assemblyspaced slightly above the supporting surface (e.g., tabletop, shelf, or floor), allowing for improved airflow and ventilation while also providing physical stability to humidifier. The slight elevation created by feetalso serves to acoustically isolate the humidifier from the surface it rests upon, reducing operational noise transmission and contributing to a quieter user experience. The portable and free-standing design of humidifierpermits it to be easily placed and operated on a variety of surfaces without requiring permanent installation, enhancing user convenience and device versatility.

is a see-through top perspective view of humidifier. Shelland/or tankmay be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing lighting assemblywithin tank, namely chamberto be seen externally by a user. The selection of material for shelland tankoptimizes the interaction between emitted light and mist flow, with translucency levels tailored to achieve a balance between light diffusion and visibility of mist movement, thereby enhancing the overall visual effect while maintaining the structural integrity required for containing fluids.

As shown in, lighting assemblycomprises of chamberthat may be in the form of a tube or other elongated member extending from bottom plateof tank. Chambermay include at least two open ends, where one end acts as a mist inlet and is in fluid communication with transducerfor receiving mist created by transducerand the other open end is a mist outletfor expelling mist created by transducerfrom humidifier through chamberand out from mist outlet. The elongated configuration of chamberfacilitates a laminar upward flow of mist, ensuring a continuous and uninterrupted mist column that can be illuminated evenly by light source, thereby maximizing the lantern or flame-like visual effect. Additionally, the vertical orientation of chamberaligns with the natural buoyancy of warm mist and airflow, promoting efficient mist propulsion through outlet.

Similar to shelland/or tank, chambermay also be made of any transparent, translucent, semi-transparent or semi-translucent material known in the art for allowing both the light emitted within chamberand the mist that flows through chamberto be seen externally by a user. The combination of the light and mist that flows through chambercreates a flame or lantern-like effect. This effect is further enhanced by the interaction of scattered light with the micron-sized mist particles, creating dynamic patterns of brightness, movement, and opacity that simulate the organic and unpredictable nature of real flames, thus offering a highly immersive and captivating visual presentation.

A valve assemblyfor controlling the flow of fluid from the tank assemblyto the base assemblyis also provided. The valve assemblyis integrated into the bottom plateof tankand regulates the delivery of fluid held within the tankto the base assembly, specifically to the transducerpositioned within the base assembly. The valve assemblygenerally comprises a fill cap seal, a spring, a pin or plunger, a cap gasket, and a fill cap.

The fill capis secured to the bottom plateof the tankand houses the internal components of the valve assembly. In one example, the fill capis removably attached to the bottom platevia a threaded engagement, allowing the fill capto be screwed on and off the bottom plateby a user. This configuration enables the user to remove the fill capto access the interior of the tankfor refilling the tankwith water through opening, and thereafter securely reattach the fill capto seal the tankfor normal operation. The fill cap sealis disposed adjacent to the fill capto provide an initial barrier against fluid leakage and to ensure that the valve assembly remains sealed when not engaged.

The springis positioned within the fill capand is operatively engaged with the pin or plunger. The springapplies a continuous biasing force to the pin/plungerin a direction toward the closed position. The pin/plungeris axially movable within the fill capbetween a sealed closed position, wherein the pin/plungerseats against the cap gasketto block the outlet openingof tank, and an open position, wherein the pin/plungeris displaced from the cap gasketto allow fluid flow through the valve assembly.

In operation, when the tankof tank assemblyis properly seated onto the base bodyof the base assembly, an actuator or actuator pin, positioned within the base body, engages the pin/plunger. Upon engagement, the actuator pinexerts an upward force on the pin/plunger, thereby compressing the springand displacing the pin/plungeraway from the cap gasket. This displacement creates a fluid pathway from the interior of the tankthrough the valve assemblyand into the base assembly, allowing fluid to flow under gravitational force to the transducerfor atomization.

The fill cap sealand cap gasketfunction cooperatively to ensure that when the actuator pinis not engaged with the pin/plunger, the valve assemblymaintains a watertight seal, preventing fluid leakage from the tank. When the tankis lifted or otherwise removed from the base body, the actuator pindisengages from the pin/plunger, permitting the springto decompress and force the pin/plungerback into sealing engagement with the cap gasket. In this closed state, the valve assemblyeffectively isolates the fluid within the tank, preventing any leakage or unintended fluid release.

The valve assemblythereby provides a simple yet highly effective mechanism for enabling and disabling fluid flow in response to the tank's engagement with the humidifier base. The use of a spring-biased pin/plungerin conjunction with dual sealing elements (fill cap sealand cap gasket) ensures reliable operation over repeated cycles of tank installation and removal, while minimizing the risk of leaks that could damage internal humidifier components or surrounding surfaces. The design further ensures that fluid flow is only enabled during proper tank seating, enhancing the overall safety and user convenience of the humidifier.

In addition to the valve assembly, the bottom plateof tankfurther includes a magnet cover. The magnet coverhouses a magnet or ferromagnetic component (not shown) that is part of a magnetic detection system for verifying proper tank placement. The magnet or ferromagnetic component housed within the magnet coveris configured to magnetically correspond, attach, or otherwise communicate with a separate magnet or ferromagnetic componentpositioned within the base assembly. The magnetmay be operatively associated with a sensorthat is in communication with a controller.

The magnetic sensor mechanism is configured to detect the presence or absence of the tankon the base body. When the tankis correctly seated on the base body, the magnetic field generated by the magnet housed within the magnet coverinteracts with the magnet, allowing the sensorto detect the magnetic coupling. Upon detecting the proper presence of the tank, the sensorsends a signal to the controller, which permits operation of the humidifier, including activation of the transduceror other internal systems. Conversely, if the tankis not properly seated on the base body, meaning the magnetic field is not detected by the sensor, the controllerprevents operation of the humidifier. This magnetic sensing mechanism serves as a safety feature, ensuring that the humidifiercannot operate when the tankis absent, improperly aligned, or improperly secured, thereby reducing the risk of malfunction, dry-running of internal components, or leakage-related hazards.

Bottom platefurther includes a transducer coverand a blower cover. The transducer coveris positioned to protect the transducerhoused within the base assembly, while the blower coveris positioned to shield blower-related components within the base assembly. Both covers,offer additional protection for the internal components of the base assemblyfrom exposure to the fluid held within the tank. These covers provide physical barriers that prevent incidental contact between water and sensitive electronic or mechanical components, thereby improving the durability, operational reliability, and safety of the humidifier. These protective covers act as physical barriers designed to compartmentalize and isolate critical electrical and mechanical parts from accidental liquid exposure, condensation, or humidity-related deterioration. The separation improves maintenance ease, reduces the risk of short circuits, minimizes mechanical contamination, and extends the overall operational lifespan of humidifier. Further, by optimizing the airflow routing within the enclosed base, these covers contribute to improved cooling of internal components such as transducerand blower, enhancing thermal management efficiency during extended operation periods.

is top perspective view of the humidifierwith the shelland tankremoved andis a top view of the humidifierof. In addition to the features described above, the humidifierincludes a chamberthat extends from the bottom plateof the tank. Chambermay be formed as a tube or other elongated member that projects upward from the base assembly. The chamberis configured such that fluid contained within the tankmay surround at least a portion of the external surface of chamber. Chamberincludes at least two open ends, wherein a first open end acts as a mist inlet that is in fluid communication with the transducerto receive mist generated by the transducer, and a second open end forms a mist outletfor expelling the mist through chamberand out of the humidifiervia a mist outlet. Submerging or closely encasing lower portion of chamberwithin the tank's water volume also enhances visual magnification effects, causing the illuminated mist to appear larger, deeper, and more dynamic to external observers.

Shown in, at least one light sourceis positioned within the base assemblyor base body. The light sourceis configured to emit light into the interior of chamberto illuminate chamberfrom within. In the present example, chamberextends between light sourceand mist outlet opening, with the light sourcepositioned generally along the same y-axis as outlet openingand/or mist outlet. However, it should be understood that in other examples, such as that shown infor humidifier, light sourcemay be positioned in any location within the base bodythat permits light to enter and illuminate the interior of the chamber. Light sourcemay be configured to illuminate only a portion of the interior of chamberor can be configured to illuminate the entire interior length of chamber. Positioning light sourcealong the principal vertical axis optimizes the directionality and uniform distribution of emitted light through rising mist columns, maximizing the simulated flame effect. Depending on user settings, light sourcemay also be configured for intensity modulation, color variation, or programmed flickering patterns to simulate different visual atmospheres, such as candlelight, bonfire glow, or soft lantern radiance.

In alternative examples, the light sourcemay be positioned within chamberitself or near mist outletor outlet, where it is configured to emit light downward into the chamberto illuminate the interior. The light sourcemay include any suitable type of light known in the art, including one or more LEDs, incandescent bulbs, tungsten lamps, fluorescent lights, or discharge lamps.

As mist is generated by the transducerand flows upward through chambertoward mist outlet, the emitted light from light sourceilluminates the mist particles traveling through the transparent, translucent, semi-transparent, or semi-translucent material forming the chamber. This combination of light and mist within chambercreates a flame-like, lantern-like, or glowing effect that is externally visible to a user, providing a visually appealing aesthetic feature that enhances the overall appearance and user experience of humidifier. The dynamic interaction between rising mist and patterned light diffusion creates an ever-changing visual landscape, mimicking the organic randomness of natural flames. This multi-sensory presentation—combining sight, ambient humidity, and often subtle sound—produces a relaxing, almost meditative user environment. As such, the humidifier of the present invention transcends pure functional humidification, evolving into an integrated ambient wellness device suitable for homes, spas, offices, and hospitality venues.

is a top perspective view of humidifierwith the chamberand bottom plate(together referred to as chamber assembly) removed. In particular,shows some of the internal components housing within base bodyof base assembly, namely, magnet, light source, transducerand blower outlet. The internal operation of humidifierincludes the use of a mist generator, such as a transducer, and at least one blowerto generate and move fine mist into the environment. Transducermay be any device capable of creating fine mist from a fluid such as water. In the present example, transduceris a piezoelectric device, such as a small disc, that vibrates at a high frequency, converting electrical energy into mechanical vibrations. These rapid mechanical vibrations generate cavitation at the fluid surface, creating a fine mist composed of micron-sized water droplets.

In operation, fluid from the tankflows to transducer, regulated by the valve assembly. The transducerthen atomizes the fluid into fine mist. A mist bafflemay also be provided to control and direct the flow of fluid mist, preventing it from splashing out and ensuring efficient distribution. Mist bafflecan also help prevent minerals in the fluid from accumulating on surfaces, significantly reducing maintenance requirements and extending the effective operational life of transducer. Specifically, mist baffleacts as a flow regulator and debris barrier, smoothing out mist trajectories to maintain a uniform upward plume, enhancing the stability and predictability of the illuminated mist column or chamber.

Simultaneously, a blowerpositioned within the base assemblygenerates a flow of air, which exits through a blower outletpositioned adjacent to transducer. The air generated by blowercaptures and entrains the mist produced by transducerand propels the mist upward through chamber. The air-mist mixture travels through the illuminated chamberand exits through the mist outletinto the surrounding environment, thereby increasing the ambient humidity. The coordinated operation of transducerand blowerensures efficient mist production and dispersion, while also enhancing the visible effect of the illuminated mist column within chamber. Blowermay be a variable-speed fan configured to adjust airflow rates depending on operating conditions or user-selected settings, thereby modulating mist output volume, height, and turbulence. This enables dynamic adjustment of the mist stream's visual behavior—from a soft, gentle candle flicker to a more energetic, fire-like plume—thereby personalizing both the humidification and aesthetic performance according to user preferences or environmental conditions. Additionally, the active entrainment of mist within the airflow ensures that mist disperses effectively throughout the ambient space rather than settling near the device, improving room-wide humidification efficiency.

In some examples, valve assemblymay be positioned in either the tank assemblyor the base assemblydepending on manufacturing preferences. The lighting assemblycomprises the combination of the light sourceand chamber, forming a key aesthetic and functional component. Power sourcemay be one or more batteries, one or more rechargeable batteries, or an external power source such as an A C wall outlet. Power sourcesupplies electrical power necessary to operate all active components of humidifier, including transducer, blower, controller, sensor, and light source.

Similarly, all features and functions and/or combination of features and functions incorporated in humidifiermay also be incorporated in humidifier. The introduction of humidifierhighlights the modularity, scalability, and cross-compatibility of the inventive platform, demonstrating how the core principles of illuminated mist presentation and safe, efficient humidification can be adapted across different design aesthetics, form factors, and market segments, including both consumer-grade and premium, high-design variants.
