Electronic Cigarette Vaporizer Equipped with Soft Vaporizing Core

The disclosure relates to the technical field of electronic cigarette vaporizers, and more particularly, the disclosure relates to an electronic cigarette vaporizer equipped with a soft vaporizing core.

An electronic cigarette generally includes a battery part and a vaporizer. Herein, the battery part may be mounted with a battery for supplying power to the vaporizer. The vaporizer may be provided with a vaporizing core, which at least comprises a liquid guiding element and a heating element. The heating element can atomize the vaporizing liquid into vapor fog for users to vape when powered on. The vaporizing liquid is namely the to-be-vaporized e-cigarette liquid. The electronic cigarette, as a vaporizing device for the vaporizing liquid, can heat and atomize the vaporizing liquid stored in the electronic cigarette into vapor fog, aerosol, vapor or the like for users to vape.

The vaporizing core of electronic cigarette vaporizers in the market generally has a structure in which a liquid guiding cotton string is wound around a heating wire and a structure in which a heating resistance is disposed on the bottom of a porous ceramic body. Herein, based on the structure in which the liquid guiding cotton string is wound around the heating wire, a relatively small amount of vapor can be produced during operation due to the small cross-sectional area of the liquid guiding cotton string that conducts the vaporizing liquid. In addition, during high-temperature operation, the poor sealing between the vaporizing base and the liquid guiding cotton string may lead to liquid leakage. Furthermore, based on the structure in which the heating resistance is disposed on the bottom of porous ceramic body, the porous ceramic body has numerous unordered micro-pores. In such a case, after a long period of operation, macromolecules, micro-particles, carbohydrates and the like contained in the e-cigarette liquid may easily accumulate and gum up the micro-pores of the porous ceramic body. Furthermore, they may be prone to charring at high temperatures to produce a burned taste. In such a case, it may result in reduced vapor amount, inconsistent tastes, impure taste, and even the burned taste during vaping. In addition, the porous ceramic body has a complicated manufacturing process, a high cost, and a low production efficiency. Moreover, the porous ceramic body, which has complex compositions not ruled out heavy metals, has a risk of heavy metal precipitation after a long period of high-temperature operation.

As the electronic cigarette vaporizers in the market generally use a straight-through airflow channel in the middle, un-vaporized droplets contained in the vaporizing liquid or the liquor condensate formed by condensation of the vapor fog on the tube wall may leak out through the air inlet provided on the bottom cap of the vaporizer, or may be inhaled by users, thereby resulting in a poor user experience.

Herein, the upper portion of the upper seat frameis provided with a discharge tube, and the lower portion is provided with a flat-shaped body, and the cross-sectional area of the discharge tubeis smaller than that of the flat-shaped body.

The bottom portion of the flat-shaped bodyis provided with a vaporizing core cavityextending upwards in a groove shape, to accommodate the soft vaporizing core. On two sides outside the vaporizing core cavity, air outlet through holesare provided, which communicate with two sides inside the discharge tubelocated above. On two sides inside the vaporizing core cavity, liquid inlet through holesare provided, which communicate with the upper surface of the flat-shaped body, at two sides outside the discharge tube. Furthermore, the flat-shaped bodyis provided with a liquid filling through hole, which allows communication between the upper and lower sides of the flat-shaped bodyand serves as a channel for filling the vaporizing liquid during assembly. After filling of the vaporizing liquid, the liquid filling through holecan be sealed with a plunger, as described later.

The upper end of the discharge tubeis connected with the mouthpiece tubeof the mouthpiece housing. The vapor channel sealing componentis connected between the discharge tubeand the mouthpiece tubeto achieve a sealed connection therebetween. The vapor channel sealing componentmay be made of a silicone rubber material. The bottom portion of the vapor channel sealing componentwhich is inserted in the discharge tubehas a reduced outer diameter, and an inverted inner annular grooveis defined between it and the inner wall of the discharge tube. This inner annular grooveserves to collect and obstruct the condensate of the vapor fog discharged through the discharge tube, thereby preventing the condensate from being inhaled by the user.

In the disclosure, the upper seat framemay be made of a rigid plastic material, and the upper seat sealing componentmay be made of a soft silicone rubber material. During production, both of them may be integrally formed through an over-molding process by rubber coating. In such a case, it has reduced number of components and accessories, simplifies the production process, facilitates easy assembly, increases production efficiency, and facilitates production automation.

As shown in, the soft vaporizing corecomprises a vaporizing core support, a heating element, and a soft liquid guiding element. The vaporizing core supporthas an upper flat surfaceand a lower flat surface, and is provided with a support through holein the middle. The heating elementincludes a sheet-like heating resistancewith a conductive path in a certain shape. The heating resistanceis disposed in the support through hole. In the embodiment, the heating resistanceis aligned or substantially aligned with the upper flat surfaceof the vaporizing core support. The soft liquid guiding elementis disposed on the upper surface of the heating resistance, with its bottom portion abutting on the heating resistance, such that the vaporizing liquid contained in the soft liquid guiding elementcan come into contact with the heating resistance, and the heating resistancecan directly heat and atomize the vaporizing liquid into vapor fog.

In the embodiment, the soft liquid guiding elementmay be made of organic cotton and formed as a block-shaped body that is cohesive and cannot be easily dispersed. That is, the soft liquid guiding elementconsists of a block-shaped body. In further embodiments, the soft liquid guiding elementmay also be made of one or a combination of more materials including ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, and PET fiber, all of which are soft materials. Due to the low cost of raw materials, the elimination of sintering process, the simple processing, and the simple structure, it is easy to mount the soft liquid guiding elementinto the vaporizer. Accordingly, it has a significantly reduced cost and an improved production efficiency. Additionally, as the material of the soft liquid guiding elementhas simple composition without heavy metals, there is no risk of heavy metal precipitation during high-temperature operation of the soft vaporizing core.

During operation, the soft liquid guiding elementconducts the vaporizing liquid from top to bottom. Its block-shaped structure achieves a large area for conducting and heating the vaporizing liquid, and avoids the shortcomings of the liquid guiding cotton string including small conduction area for conducting vaporizing liquid, small amount of vapor produced during operation, and being prone to liquid leakage during high-temperature operation. As the soft liquid guiding elementuses the abovementioned soft cotton-like materials which all have a loose fiber structure, the vaporizing liquid can be conducted through the gaps between the fiber structures, without the need for microporous conduction. Hence, it can achieve quick liquid conduction and maintain a greater vaporization amount. Compared to rigid porous ceramic bodies, it avoids the shortcomings that macromolecules, micro-particles, carbohydrates and the like contained in the vaporizing liquid may easily accumulate and gum up the micro-pores and may be prone to charring at high temperatures to produce a burned taste.

Herein, the heating elementfurther comprises electrode contact disksconnected with both ends of the heating resistance. The electrode contact disksare disposed on the lower flat surface of the vaporizing core supportand positioned on both sides of the support through hole. The electrode contact disksallow the columnar electrodesto abut thereon, to supply power.

On two sides of the heating resistanceand the electrode contact disks, several fixing clawsare provided, which extend into the interior of the vaporizing core support. The fixing clawsfacilitate firmer fixing on the vaporizing core support. In the disclosure, the vaporizing core supportmay be made of heat-resistant plastic materials. The heating elementcan be placed in the mold before the injection molding of the vaporizing core support, such that it can be formed integrally with the vaporizing core support. In particular, as the fixing clawsare molded in the vaporizing core support, they can be more firmly connected, preventing the heating elementfrom detaching from the vaporizing core support.

In the embodiment, the conductive path of the heating resistancemay be designed in a shape of several repeated S. In further embodiments, it may also be designed in other shapes and thus is not limited to the S-shape. The heating resistanceis generally composed of a metal heating resistance. The soft liquid guiding elementcan absorb, store, and conduct the vaporizing liquid. The heating resistanceabuts against the lower portion of the soft liquid guiding element. Thus, in the case that the heating resistancegenerates heat when powered on, it heats, vaporizes and atomizes the vaporizing liquid in the lower portion of the soft liquid guiding elementinto vapor fog, which then can be dispersed downwards through the support through hole.

Referring to, the soft vaporizing corein a further embodiment further comprises a permeable sheetprovided with permeation holes (not shown in the drawings). The thickness of the permeable sheetmay be set between 0.5 mm and 2 mm. The permeable sheetis disposed between the soft liquid guiding elementand the support. Herein, the diameter of the permeation holes of the permeable sheetmay be set between 50 μm and 2 mm. In the embodiment, the permeable sheetserves to support the soft liquid guiding elementfrom below and prevents it from deforming or sagging under a long period of high-temperature operation. Meanwhile, it allows the vaporizing liquid stored in the soft liquid guiding elementto be slowly released onto the heating resistancethrough the permeation holes. During operation, it can balance the evaporation rate of the vaporizing liquid with its permeation rate. When the vaporization is inactivated, the vaporizing liquid flowing through the permeation holes can achieve another kind of balance due to the surface tension, preventing dripping or leakage of the vaporizing liquid. The permeable sheetmay be made very thin and made of high-temperature-resistant, non-conductive materials, such as plastic, silicone, porous ceramic body, diatomaceous earth, etc.

The columnar electrodesserve to support the soft vaporizing corefrom below, and meanwhile abut on the electrode contact diskto supply power for the heating resistance.

The base seat frameis provided with a vaporizing grooveat a position below the soft vaporizing core. The bottom portion of the vaporizing grooveis provided with a third air inlet hole. One side of the lower end of the base seat frameis provided with a first air inlet grooveextending upwards. The base seat sealing componentis provided with a second air inlet holeat a position below the first air inlet groove. A second air inlet tube wallis provided, which extends upwards from the second air inlet hole, above the upper end surface of the base seat sealing component. The second air inlet tube wallextends into the first air inlet groove.

The base seat frameis provided with a plungerprotruding upwards. The plungerserves to plug the liquid filling through holeafter filling to prevent liquid leakage. The base seat frameis further provided with two first mounting holes. The bottom portion of the base seat frameis further provided with four first securing posts. The upper portion of the base seat sealing componentis further provided with two second securing postsand four second mounting blind holes. The second securing postsextend upwards through the first mounting holesto be fixed, to enable positioning, mounting, and fixation of the base seat frameand the base seat sealing component. The first securing postsare mounted into the second mounting blind holes, to enable positioning, mounting, and fixation of the base seat frameand the base seat sealing component.

As shown in, two PCB electrodes (not shown in the drawings) are disposed under the PCB circuit board, the bottom capis provided with bottom cap electrode holesat a position corresponding to the PCB electrodes. The PCB electrodes are exposed from the bottom cap electrode holes, to allow the electrodes of the e-cigarette battery to abut on the PCB electrodes. The bottom capis further provided with several first air inlet holesat a position corresponding to the second air inlet hole.

As shown in, the mouthpiece housingis provided with an internal cavity. After mounting of the vaporization assemblyinto the mouthpiece housing, the cavity defined between the inner wall of the mouthpiece housing, the upper seat frame, and the mouthpiece tubeserves as a liquid storage chamberfor storing vaporizing liquid.

Referring to, during operation of the electronic cigarette vaporizer of the disclosure, the user may vape through the mouthpiece opening, to generate a negative pressure inside the vaporizer. Consequently, outside air may enter from the first air inlet holesprovided on the bottom cap of the vaporizer, flow into the second air inlet holeand corresponding second air inlet tube wall, and then enter the first air gapin the first air inlet groove. Then, the air entered the first air gapmay reverse direction and flow downwards into the second air gap. After that, it may transversely flow into the second air inlet grooveof the base seat sealing component, and then flow upwards to the third air inlet holeand then enter the vaporizing groove. At this moment, as the vaporizing liquid in the liquid storage chamberhas already flowed downwards into the soft vaporizing corethrough the liquid inlet through holesprovided on two sides outside the discharge tube, the heating resistance, which is powered on to generate heat, can heat, vaporize, and atomize the vaporizing liquid in the lower portion of the soft liquid guiding elementinto vapor fog. Then, the vapor fog which flows downwards into the vaporizing groovecan be carried by the entered air, to flow upwards through the air outlet through holeinto the interior of the discharge tube, and then flow through the mouthpiece tubeand flow out from the mouthpiece openingto be inhaled by the user finally. The abovementioned directions and paths of the airflow are indicated by the series of hollow arrows as shown in.

The internal structure of the electronic cigarette vaporizer of the disclosure is provided with the air pathway including the first air inlet holes, the second air inlet hole, the first air gap, the second air gap, the second air inlet groove, the third air inlet hole, and the vaporizing groove. Such an air pathway, which consists of a plurality of path sections, is multi-turn and tortuous. It allows outside air to enter smoothly, and meanwhile prevents the liquor condensate dropped into the vaporizing chamber from flowing downwards and leaking out reversely through the first air inlet holes.

As mentioned above, according to the electronic cigarette vaporizer with a soft vaporizing core of the disclosure, the soft liquid guiding element is easy to be mounted into the vaporizer and achieves an improved production efficiency due to the low cost of raw materials, the elimination of sintering process, the simple processing, and the simple structure. As the soft liquid guiding element conducts the vaporizing liquid from top to bottom, it achieves a large area for conducting and heating the vaporizing liquid, and avoids the shortcomings of the liquid guiding cotton string including small conduction area for conducting vaporizing liquid, small amount of vapor produced during operation, and being prone to liquid leakage during high-temperature operation. In addition, as the soft liquid guiding element for conducting the vaporizing liquid has a loose fiber structure, it eliminates the need for microporous conduction. It avoids the shortcomings that, during operation of the porous ceramic body, macromolecules, micro-particles, carbohydrates and the like contained in the vaporizing liquid may easily accumulate and gum up the micro-pores of the porous ceramic body and may be prone to charring at high temperatures to produce a burned taste. Hence, it can maintain great vaporization amount and consistent and pure taste, prevent burned taste, and improve user experience. Due to the low cost of raw materials, the elimination of sintering process, the simple processing, and the simple structure, it is easy to mount the soft liquid guiding element into the vaporizer, thereby significantly reducing the cost and improving production efficiency. Moreover, as the material of the soft liquid guiding element has simple composition without heavy metals, there is no risk of heavy metal precipitation during high-temperature operation of the soft vaporizing core.

The vaporizer of the disclosure has multi-turn and tortuous air pathway consisting of a plurality of path sections, which allows outside air to enter smoothly, and meanwhile prevents the liquor condensate dropped into the vaporizing chamber from leaking out reversely through the bottom cap. In addition, the inverted inner annular groove of the vapor channel sealing component can collect and obstruct the condensate of the vapor fog that is discharged, to prevent the condensate from being inhaled by the user and thus improve user experience.
