With the advancement of small household electrical appliance technology, the problem of indoor dryness in autumn and winter has been alleviated. The emergence of humidifiers can increase indoor air humidity, making it more suitable for living. In addition to the basic function of increasing humidity, humidifiers can also be used in combination with aromatic essential oils, air fresheners, Chinese herbal medicines, and other functional components. The water mist containing these functional components can be sprayed into the air, thereby achieving effects such as mood relaxation, disease treatment, and air quality improvement, providing users with a better experience.

However, common humidifiers typically have straight spray outlets, with water mist fixedly sprayed in one direction, resulting in a very limited spray range. This causes the sprayed water mist to distribute unevenly and creates dead zones. Users usually have to move the humidifier to obtain different spray positions and/or directions, which is inconvenient.

To address the above technical problems, inventors of the present disclosure have proposed at least the following embodiments after long-term research.

Referring to,is a schematic perspective view of an assembled spray device according to an embodiment of the present disclosure from one angle.is a schematic perspective view of the assembled spray device according to an embodiment of the present disclosure from another angle.is a schematic sectional view of the spray device from the angle as shown in.is an enlarged view of an area “A” shown in. An embodiment of the present disclosure provides a spray devicefor generating aerosols and transferring them outwardly. The spray deviceinclude a device body, an upper cover, and a movable member.

The device bodydefines a mist generation chamber. The upper coveris connected to the device bodyand defines a through hole. A mist generating uniteis mounted in the installation cavityso that mist is generated in the mist generation chamber. The movable memberis mounted in the upper coverand is rotatable relative to the upper cover. The movable memberis provided with a mist outletthrough which mist generated in the mist generation chamberis sprayed out of the spray device. At least a portion of the movable memberis exposed to the upper coverthrough the through hole. As the movable memberrotates, the mist outletcan be oriented in different directions so that the mist can be sprayed out through the mist outletin different directions.

Specifically, the movable memberis capable of rotating relative to the installation cavityin two directions. The upper covercan also defines an installation cavity. The through holecommunicates with the installation cavity. The movable memberis movably mounted in the installation cavity. The mist outletis in communication with the mist generation chamber. At least a portion of the movable memberis exposed to the installation cavitythrough the through hole. The movable membercan further define a mist channel. The mist outletcommunicates with the installation cavityvia the mist channel.

In the structure provided in this embodiment, by rotatably installing the movable memberin the installation cavityand allowing a portion of the movable memberto extend to be exposed to the outside of the spray devicethrough the through hole, the orientation of the mist outletprovided on the movable membercan be adjusted by rotating the movable member. When the mist outletis rotated to a position where it is exposed through the through hole, aerosols from the mist channelcan be sprayed in different directions through the mist outlet, achieving the effect of flexibly adjusting the orientation of the mist outlet. This enables the spray deviceto spray aerosols in multiple directions, thereby enhancing the usability of the spray device.

In a specific embodiment of the present disclosure, a first spherical surfacecan be provided on the movable member, like on the outer periphery of the movable member, and the movable membercan have an outer contour that is at least partially spherical. The upper covermay be provided with a second spherical surfacethat corresponds to the first spherical surface, allowing the first spherical surfaceto cooperate with the second spherical surface. The second spherical surfacecan be provided on the inner wall of the installation cavity.

In the structure provided in this embodiment, the movable membercan rotate relative to the installation cavityin multiple directions due to the cooperative relationship between the first spherical surfaceand the second spherical surface. This allows the mist outletto be oriented in different directions as the first spherical surfacerotates, enabling the spray deviceto spray aerosols in various directions.

Optionally, at least a portion of the first spherical surfaceis exposed to the outside of the spray devicethrough the through hole, with the mist outletbeing provided on the first spherical surface. This allows the mist outletto be oriented in different directions as the first spherical surfacerotates.

In a specific embodiment of the present disclosure, the movable membercan also include a control handle, which allows the user to rotate the movable membervia the control handle. Specifically, the control handleis provided on the movable memberand exposed to the outside of the spray devicethrough the through hole.

In the structure provided in this embodiment, the exposed control handlecan be gripped or operated by the user, enabling the user to control the rotation of the movable memberand the mist outletto a desired position, thereby enhancing the usability of the spray device.

Further, the control handleand the edge of the through holecan also have an abutting relationship. This allows the control handleto limit the rotation range of the movable memberto a certain extent, reducing the probability that the movable memberwill rotate to an abnormal position so that the spraying devicewill not work normally.

In a specific embodiment of the present disclosure, the upper covermay have a limiting surfaceformed in the installation cavity. Specifically, the limiting surfacemay be formed on the inner wall of the installation cavity. When the movable memberis moved to a predetermined position, at least a portion of the movable memberis limited by the limiting surface.

Optionally, the limiting surfacemay be formed at the bottom of the installation cavity. The lower end of the movable memberabuts against the limiting surfaceat the bottom of the installation cavity, thereby limiting the rotation range of the movable memberand reducing the probability of the movable memberrotating to an abnormal position that may cause the spray deviceto malfunction.

In addition, the movable membermay have a limiting edge. When the movable memberis rotated relative to the installation cavityto a certain position, the limiting surfaceabuts against the limiting edge, thereby limiting the rotation range of the movable member. This reduces the probability of the movable memberrotating to a misaligned position that may cause the spray deviceto fail to function properly, thereby enhancing the stability of the spray device.

In a specific embodiment of the present disclosure, the movable membermay have an inletat an end of the mist channelthat is substantially opposite to the mist outlet. The device bodymay also define a mist generation chamber. The device bodymay include a connecting portion. The connecting portionis located between the mist generation chamberand the installation cavity, and is used to communicate the installation cavityto the mist generation chamber. The inletcan be connected to the connecting portion. The limiting edgeis provided on the movable memberaround the inlet, and the limiting surfaceis provided around the connecting portion.

In the structure provided in this embodiment, by providing the limiting surfacearound the connecting portionand allowing the inletwhere the limiting edgeis arranged to be connected to the connecting portion, the limiting surfaceand the limiting edgecan limit the rotation of the movable member. This ensures that the mist generation chambercan always communicate with the mist channelvia the connecting portion. During the rotation of the mist outletwith the movable member, the aerosols generated in the spray devicecan always enter the mist channelvia the connecting portion. When the mist outletis exposed, the aerosols can be smoothly discharged, thereby reducing the probability of the outflow of the aerosols being affected by the rotation of the movable memberand enhancing the usability of the spray device.

In a specific embodiment of the present disclosure, the mist outletmay include at least one of an obround hole, a circular hole, or a polygonal hole.

Specifically, the mist outletmay include an obround hole. The obround hole is elongated, which increases the radiation area of the aerosols when sprayed, thereby expanding the mist angle and enhancing the usability of the spray device. Furthermore, the obround hole may have a certain curvature, which can further increase the spray direction and expand the mist angle.
