[0031] A traditional electronic atomization device usually includes a power supply device and an atomizer. The power supply device is used to supply power to the atomizer. The atomizer usually includes an internally hollow shell and an atomization component arranged in the shell. An air outlet channel is provided in the shell, and an air outlet for suction is provided on the shell corresponding to the air outlet channel. A liquid storage chamber for supplying atomization liquid to the atomization component is provided inside the shell. The atomization component is used to heat the atomization liquid supplied by the atomization liquid storage chamber to form an inhalable aerosol leading to the air outlet channel.

[0032] However, the traditional atomizer has the following problems during use: 1. Part of the atomized atomized liquid will condense and adhere to the inner wall of the air outlet channel to form condensed liquid, resulting in a low utilization rate of the atomized liquid; 2. The condensed liquid attached to the inner wall of the air outlet channel will be sucked into the mouth by the user, thereby affecting the user's suction experience; 3. The condensed liquid attached to the inner wall of the air outlet channel will leak through the air inlet end of the air outlet channel. For this reason, it is urgent to optimize the traditional electronic atomization device to solve the above technical problems. The optimized electronic atomization device of this application will be described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figures 1 to 3 According to an embodiment of the present application, the electronic atomization device includes a power supply device (not shown in the figure) and an atomizer. The power supply device is used to supply power to the atomizer. The atomizer includes a shell 100, an atomization assembly 200 and an oil suction member 300.

[0034] Among them, the shell 100 is an internal hollow cavity structure, and the shell 100 is provided with a liquid storage chamber 110, an atomization channel 231 and an air outlet channel 121 which are connected in sequence. The atomization assembly 200 includes an atomization core, which is arranged in the shell 100. The atomization core is used to heat the atomization liquid supplied by the atomization liquid storage chamber 110 to form an inhalable aerosol leading to the air outlet channel 121 in the atomization channel 231. The oil absorption component 300 is arranged in the shell 100 and is physically isolated from the liquid storage chamber 110. The oil absorption component 300 is configured to be at least partially able to contact the condensate attached to the inner wall of the air outlet channel 121. The oil absorption component 300 is used to absorb the condensate attached to the inner wall of the air outlet channel 121 and transport the absorbed condensate to the atomization core for reheating and atomization.

[0035] When in use, the oil absorption component 300 can absorb the condensed liquid attached to the inner wall of the air outlet channel 121 and can transport the absorbed condensed liquid to the atomization core for reheating and atomization, which is beneficial to improving the utilization rate of the atomized liquid. At the same time, it is beneficial to reduce the situation where the condensed liquid attached to the inner wall of the air outlet channel 121 is sucked into the mouth of the user (the condensed liquid attached to the inner wall of the air outlet channel 121 can be absorbed by the oil absorption component 300 in time), thereby helping to improve the user's suction experience. In addition, it is beneficial to reduce the probability of the condensed liquid attached to the inner wall of the air outlet channel 121 leaking through the air inlet end of the air outlet channel 121 (the condensed liquid attached to the inner wall of the air outlet channel 121 can be absorbed by the oil absorption component 300 in time).

[0036] It should be noted that, in some of the embodiments, the oil absorption member 300 is made of a long fiber material. Specifically, the long fiber material refers to a fiber material with a fiber length of 5 mm to 33 mm. The long fiber material has a strong capillary effect, and the surface of the long fiber material is relatively smooth and has less fluff, which facilitates the condensate absorbed by the oil absorption member 300 to flow to the atomization assembly 200 under the action of gravity.

[0037] Reference Figure 1 In some of the embodiments, the oil suction member 300 is spaced apart from the atomizer core (ie, the oil suction member 300 is not in contact with the atomizer core), which helps prevent the atomizer core from transferring the atomized liquid supplied by the liquid storage chamber 110 to the oil suction member 300 .

[0038] It should be noted that, in some other embodiments, the oil absorption member 300 and the atomization core may also be arranged in contact with each other, which is not limited here.

[0039] Reference Figures 1 to 3 In some embodiments, the oil-absorbing member 300 is a tubular structure, a first entity structure 120 and a second entity structure 130 are provided in the housing 100, an air outlet channel 121 is formed inside the first entity structure 120, and the second entity structure 130 is arranged at intervals around the first entity structure 120, so that an installation space 140 with a ring-shaped cross section and connected to the atomizer core fluid is formed between the first entity structure 120 and the second entity structure 130, and the oil-absorbing member 300 is embedded in the installation space 140, and a plurality of through holes 122 for connecting the air outlet channel 121 and the installation space 140 are arranged at intervals on the first entity structure 120, so that the oil-absorbing member 300 can absorb the condensate attached to the inner wall of the air outlet channel 121, and because the installation space 140 leads to the atomizer core, the condensate absorbed by the oil-absorbing member 300 can flow to the atomizer core under the action of gravity for atomization again, and the above structure is simple and easy to implement, and is also convenient for production and assembly. Among them, the oil suction member 300 is a tubular structure, which is beneficial to increasing the volume of the oil suction member 300 compared with other shapes, thereby facilitating increasing the maximum adsorption amount of the oil suction member 300 on the condensate attached to the inner wall of the air outlet channel 121, and at the same time, it is beneficial to increase the area covered by the oil suction member 300, thereby facilitating improving the adsorption effect of the oil suction member 300 on the condensate attached to the inner wall of the air outlet channel 121.

[0040] It should be noted that, in some other embodiments, the above-mentioned through hole 122 may also be replaced by a through groove, which is not limited here.

[0041] It should be noted that, in some other embodiments, the oil absorption member 300 may also be a sheet structure with a rectangular or arc-shaped cross-section. In this case, there are multiple oil absorption members 300, and the multiple oil absorption members 300 are arranged at circumferential intervals along the air outlet channel 121. Accordingly, the shape of the installation space 140 can be adaptively adjusted, and is not limited here.

[0042] Reference Figure 1 and Figure 3 In some embodiments, a housing chamber 131 located below the oil absorbing member 300 and connected to the installation space 140 is provided in the second entity structure 130, the atomizer core is accommodated in the housing chamber 131, and the cavity wall of the housing chamber 131 is provided with an oil inlet hole 132 for connecting the housing chamber 131 with the liquid storage chamber 110, and the atomizer channel 121 is formed in the space surrounded by the atomizer core, and the atomizer channel 121 is connected to the air outlet channel 121. The atomized liquid in the liquid storage chamber 110 flows to the atomizer core accommodated in the housing chamber 131 through the oil inlet hole 132, which is conducive to controlling the supply rate of the atomized liquid in the liquid storage chamber 110 compared to the case where the atomizer core is completely placed in the liquid storage chamber 110, thereby helping to reduce the probability of leakage of the atomized liquid in the liquid storage chamber 110 due to excessive supply.

[0043] It should be noted that, in some other embodiments, the atomization channel 121 may also be formed between the atomization core and a portion of the cavity wall of the accommodating cavity 131 , which is not limited here.

[0044] Reference Figure 1 and Figure 3 In some embodiments thereof, one end of the first entity structure 120 away from the atomizer core and one end of the second entity structure 130 away from the atomizer core are both connected to the shell 100, one end of the first entity structure 120 close to the atomizer core is located in the second entity structure 130, and there is a distance between one end of the first entity structure 120 close to the atomizer core and one end of the second entity structure 130 close to the atomizer core to form a accommodating cavity 131, which has a simple structure and is easy to implement.

[0045] Reference Figures 1 to 3In some embodiments, the atomizer further includes a filter element 400, which is a porous structure. The filter element 400 is movably disposed in the air outlet channel 121, wherein the activity space of the filter element 400 is limited in the air outlet channel 121, so that the filter element 400 can float up and down in the air outlet channel 121 under the action of the airflow generated when the user inhales and the filter element 400's own gravity, and the size of the through hole 122 and the size of the above-mentioned through groove are both smaller than the outer size of the filter element 400 to prevent the filter element 400 from being stuck in the through hole 122 or the above-mentioned through groove. During the user's inhalation process, the filter element 400 floats up and down in the air outlet channel 121 under the action of the airflow generated by the user's inhalation and the filter element 400's own gravity. At this time, the filter element 400 with a porous structure can allow the aerosol to pass through and can absorb the condensed atomized liquid in the air outlet channel 121, so that the aerosol flowing through the air outlet channel 121 can be filtered, which is beneficial to further improve the user's inhalation experience; after the user finishes inhaling, the filter element 400 moves to the air inlet end of the air outlet channel 121 under the action of its own gravity. At this time, the condensed liquid absorbed by the filter element 400 can be removed by the action of gravity. At the same time, the condensed liquid adsorbed by the filter element 400 can flow to the oil absorption member 300 through the through hole 122 or the above-mentioned through groove under the action of capillary force, and then flow to the atomization core through the oil absorption member 300, thereby releasing the condensed liquid adsorbed by the filter element 400. In addition, the condensed liquid attached to the inner wall of the air outlet channel 121 can be adsorbed by the filter element 400 located at the air inlet end of the air outlet channel 121 when it converges to the air inlet end of the air outlet channel 121 under the action of gravity, thereby helping to further reduce the probability of the condensed liquid attached to the inner wall of the air outlet channel 121 leaking through the air inlet end of the air outlet channel 121.

[0046] Reference Figure 1 and Figure 3 In some embodiments, an air outlet 150 (for user inhalation) connected to the air outlet channel 121 is provided at the top of the shell 100, and the diameter of the air outlet 150 is smaller than the outer dimension of the filter element 400 to limit the filter element 400 from being separated from the air outlet channel 121 at the air outlet 150. An air inlet 123 (i.e., the air inlet end of the air outlet channel 121) connected to the air outlet channel 121 is provided at the bottom of the first solid structure 120, and the top of the atomizer core abuts against the air inlet 123 to limit the filter element 400 from being separated from the air outlet channel 121 at the air inlet 123.

[0047] Reference Figure 1 and Figure 2 In some of the embodiments, the filter element 400 is a spherical structure, which is more advantageous than other shapes in preventing the filter element 400 from getting stuck when floating up and down in the air outlet channel 121 .

[0048] It should be noted that, in some other embodiments, the filter element 400 may also be a cylindrical structure, which is not limited here.

[0049] It should be noted that, in some of the embodiments, the filter element 400 is made of short fiber material. Specifically, the short fiber material refers to a fiber material with a fiber length of less than 5 mm. The short fiber material has strong entanglement and wrapping properties, and the surface of the short fiber material has more messy fluff, which is convenient for storing condensate.

[0050] It should be noted that in some embodiments, the oil absorbing member 300 and the filter member 400 can be made of cotton fibers among natural fibers, which can be directly obtained from nature, are natural and pollution-free, have a high safety factor, and cause little pollution to the environment. Moreover, as natural fibers, cotton fibers have no additives and will not affect the user's suction taste, so that the user has a pure taste when smoking. Of course, the oil absorbing member 300 and the filter member 400 can also be made of chemical fibers, the processing and manufacturing process of chemical fibers is relatively mature, and the length of the fibers can be adjusted as needed.

[0051] Reference Figures 1 to 3In some embodiments, the atomizer assembly 200 further includes a bracket 210 and a seal 220. The bottom of the housing 100 is an open structure. The bracket 210 is embedded in the housing 100 and assembled at one end of the second entity structure 130 close to the atomizer core. The seal 220 is arranged between the inner wall of the housing 100 and the bracket 210. The atomizer core includes a porous oil guide member 230 and a heating element 240. The heating element 240 is arranged on the porous oil guide member 230. The atomization channel 231 is formed in the space surrounded by the porous oil guide member 230. The component 230 is arranged at the top of the bracket 210, and the top of the porous oil guide component 230 abuts against the air inlet 123. The diameter of the atomization channel 231 is smaller than the outer dimension of the filter 400, so that the porous oil guide component 230 can limit the filter 400 from being separated from the air outlet channel 121 at the air inlet 123. The bracket 210 is provided with an air inlet hole 211 connected to the atomization channel 231. The heating element 240 is arranged in the atomization channel 231 and fits with the porous oil guide component 230. The above structure is simple and easy to implement, and is also convenient for production and assembly. Specifically, a buckle structure for fixing the bracket 210 is provided between the bracket 210 and the housing 100, and the sealing component 220 is a silicone sealing ring. Of course, the above buckle structure can also be replaced by screws or other structures capable of fixing the bracket 210, and the above silicone sealing ring can also be replaced by a rubber sealing ring or other sealing structures, which are not limited here. Among them, even if the condensate attached to the inner wall of the air outlet channel 121 flows out from the air inlet 123 under the action of gravity, it will be adsorbed by the porous oil guide part 230 abutting against the air inlet 123, which is beneficial to further reduce the probability of the condensate attached to the inner wall of the air outlet channel 121 leaking through the air inlet end of the air outlet channel 121.

[0052] It should be noted that, in some other embodiments, the atomization channel 231 may also be formed between the porous oil guide member 230 and the bracket 210, which is not limited here.

[0053] It should be noted that, in some embodiments, the porous oil-conducting member 230 is made of oil-conducting cotton or porous ceramics.

[0054] It should be noted that in some embodiments, the heating element 240 is a heating wire attached to the porous oil guide member 230. Of course, the heating element 240 can also be a sheet structure attached to the porous oil guide member 230 and attached with a heating film, and the heating element 240 can also be a sheet or mesh heating structure built into the porous oil guide member 230, which is not limited here.

[0055] Reference Figure 1In some embodiments, the atomizing assembly 200, the inner wall of the housing 100 and the second solid structure 130 enclose a liquid storage chamber 110 for storing atomized liquid. Of course, the liquid storage chamber 110 may also be an independently arranged cavity structure, which is not limited here.

[0056] It should be noted that, in some other embodiments, a mesh limiting structure may be provided at the air inlet 123 and the air outlet 150 to limit the filter element 400 from being separated from the air outlet channel 121 , which is not limited here.
