[0025] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The electronic atomization device currently on the market includes an atomizer and a power supply component. The power supply component provides electrical energy to the atomizer to atomize the atomization medium in the atomizer to generate an aerosol. The atomized liquid often leaks onto the outer surface of the atomizer, which not only stains the user's hands, but also affects the user's inhalation experience, thus resulting in an extremely poor user experience.

[0027] Based on this, an embodiment of the present application provides an atomizer, which is arranged in the air duct of the atomizer through an oil-blocking component, so as to prevent the atomized liquid in the atomizer from leaking to the outer surface of the atomizer, thereby improving the user experience. More specifically, the oil-blocking component includes an oil-blocking film, which is an oil-proof ventilation film or cloth, and is arranged between the air inlet and the atomization core of the atomizer to prevent the liquid in the atomizer from leaking out from the air inlet, thereby avoiding leakage and improving the user experience.

[0028] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0029] See also Figure 1 to Figure 2 , Figure 1 It is a simple schematic diagram of an electronic atomization device provided in one embodiment of the present application; Figure 2This application provides an embodiment Figure 1 A cross-sectional view of an atomizer of the electronic atomization device shown in one direction; Figure 3 This application provides an embodiment Figure 1 A cross-sectional view of the atomizer of the electronic atomization device shown in another direction. In the present embodiment, an electronic atomization device is provided, which can be used in the fields of beauty, medical treatment, electronic cigarettes, etc. The electronic atomization device includes an atomizer 100 and a power supply assembly 200. The power supply assembly 200 is electrically connected to the atomizer 100, and is used to supply power to the atomizer 100. The atomizer 100 is used to atomize the atomization medium to form an aerosol when powered on. The atomized liquid can be a liquid medicine formed by dispersing a certain medicine in a liquid solvent, an oil with added aroma components, or any other liquid suitable for atomization, such as tobacco oil.

[0030] See also Figure 2 The atomizer 100 includes a shell 1, an atomizer core 2, an oil-blocking assembly 78, and a base 5. One end of the shell 1 is a closed end, and a cigarette holder 11 is provided at the closed end; the other end of the shell 1 is an open end, and an oil storage cavity 12 is provided between the closed end and the open end; the atomizer core 2 is provided in the oil storage cavity 12, and is used to atomize the atomized liquid in the oil storage cavity 12; an air passage 14 is provided in the atomizer core 2, and one end of the air passage 14 extends to the cigarette holder 11, and is connected to the cigarette holder 11. The base 5 is arranged in the open end of the shell 1, and the base 5, the atomizer core 2 and the shell 1 define an oil storage chamber 12. The base 5 is provided with an air inlet 9, and the other end of the air passage 14 extends to the air inlet 9 and is communicated with the air inlet 9; the oil-blocking component 78 is arranged between the base 5 and the atomizer core 2, and covers the air passage 14, so that air can pass through the oil-blocking component 78 smoothly and prevent the liquid in the air passage 14 from leaking from the air inlet 9 to the direction away from the atomizer core 2.

[0031] In some embodiments, the oil-blocking component 78 includes a bracket 8 and an oil-blocking film 7. The oil-blocking component 78 is molded in the base 5 by in-mold injection molding, so that the bracket 8 and the base 5 are fused to form a whole. Therefore, the welding sealing effect of the bracket and the base is better, and the atomized liquid is not easy to leak. At the same time, the oil-blocking film 7 covers the air inlet 9 to further prevent the atomized liquid in the atomizer 100 from leaking from the air inlet 9.

[0032] The oil-blocking film 7 is formed in the bracket 8 by in-mold injection molding, that is, the oil-blocking film 7 is placed in the mold of the bracket 8, and then the molten plastic is injected into the bracket 8 mold to form the oil-blocking assembly 78, which prevents the oil-blocking film 7 from wrinkling, deformation, etc., so as to improve the injection molding efficiency. The bracket 8 is provided with a through hole, so the oil-blocking film 7 is sealed in the through hole, and the edges of the oil-blocking film 7 along the through hole are all welded and fixed by the bracket 8.

[0033] In other embodiments, the oil-blocking film 7 is formed in the base 5 by in-mold injection molding and covers the air inlet 9 to prevent the atomized liquid from leaking from the air inlet 9. The bracket 8 is not required, which saves costs and improves production efficiency.

[0034] Specifically, the oil-blocking film 7 is molded in the base 5 by in-mold injection molding as an example: the atomizer 100 includes a shell 1 and an atomizer core 2. The atomizer core 2 is arranged in the shell 1 and communicated with the oil storage chamber 12. The atomizer core 2 absorbs the atomized liquid in the oil storage chamber 12 and atomizes it to generate an aerosol. The user inhales the aerosol through the cigarette holder 11 to solve the problem of smoking addiction. The corresponding end of the cigarette holder 11 is provided with a base 5. One end of the atomizer core 2 is sealed and connected to the cigarette holder 11 through a sealing seat 6, and the other end of the atomizer core 2 is connected to the base 5. Therefore, the base 5, the inner wall of the shell 1, and the atomizer core 2 define and constitute the oil storage chamber 12, and the oil storage chamber 12 is used to store the atomized liquid; the atomizer core 2 is provided with an air duct 14, and the base 5 is provided with an air inlet 9 connected to the air duct 14. When the user inhales the aerosol, air enters the air duct 14 from the air inlet 9 and mixes with the aerosol to the user's mouth. An oil-blocking film 7 is provided on the base 5, and the oil-blocking film 7 covers the air inlet 9, so as to prevent the atomized liquid from splashing and turning into liquid and flowing out of the air inlet 9 when the atomizer core 2 is working, or to prevent the condensed liquid of the aerosol from flowing out of the air inlet 9 when the atomizer core 2 is not working, thereby improving the user experience of using the atomizer 100.

[0035] In some embodiments, the base 5 and the oil-blocking film 7 are formed into an integrated structure by in-mold injection molding, that is, the oil-blocking film 7 is placed in the mold of the base 5, and then molten plastic is injected into the mold of the base 5. After cooling and demolding, the base 5 is obtained, so that the molten plastic and the oil-blocking film 7 are welded and sealed to avoid the formation of gaps at the connection between the edge of the oil-blocking film 7 and the base 5 and the leakage of the atomized liquid. At the same time, it has good stability, is not easy to wrinkle, and does not require manual assembly, thereby improving production efficiency.

[0036] In other embodiments, the shape of the oil-blocking film 7 may be circular, elliptical, racetrack-shaped, square, etc., which is not limited here.

[0037] In some other embodiments, the number of the air inlets 9 may be 2, 3, 4, 5 or more, which is not limited here.

[0038] In some embodiments, the atomizer 100 also includes a fixing seat 3, which is connected above the base 5 and connected to the inner wall of the outer shell 1; a first molded part 4 is arranged between the outer shell 1, the fixing seat 3 and the base 5, and the first molded part 4 is molded between the outer shell 1, the fixing seat 3 and the base 5 by in-mold injection molding, and is welded and sealed therewith to prevent the atomized liquid or other condensed liquid in the oil storage chamber 12 from leaking from the matching gaps of the base 5, the outer shell 1 and the fixing seat 3, thereby improving the quality of the atomizer 100.

[0039] For details, please refer to Figures 2 to 4 The atomizer core 2, the fixing seat 3, the base 5 and the shell 1 are assembled to form an assembly, and the assembly is implanted into a mold to form a first molded part 4 by injection molding, so that the first molded part 4 can be welded and sealed with the fixing seat 3, the base 5 and the shell 1 to form an integrated structure, which cannot be disassembled, to avoid gaps in the connection between the fixing seat 3, the base 5 and the shell 1 to cause leakage of atomized liquid, and to avoid cracks in the fixing seat 3, the base 5 and the shell 1 during the assembly process and falling off during transportation.

[0040] In some embodiments, see Figures 2 to 4 , a bracket 8 is provided on the edge of at least one side of the oil-blocking film 7, and the bracket 8 and the base 5 are welded and sealed by in-mold injection molding; that is, the oil-blocking film 7 is fixed to the base 5 by the bracket 8, and the bracket 8 and the base 5 are welded and sealed by in-mold injection molding. It can also be understood that the oil-blocking film 7 is fixed by the bracket 8, and then the bracket 8 is implanted in the mold of the base 5 for injection molding, so that the bracket 8 and the base 5 are welded and sealed to form an integrated structure, thereby reducing deformation and wrinkling of the oil-blocking film 7, so as to improve the yield rate and production efficiency.

[0041] In some embodiments, see Figure 3 to Figure 4 , an oil-absorbing cotton 13 is arranged on the side of the oil-blocking film 7 facing the oil storage chamber 12, and the oil-absorbing cotton 13 is used to absorb the atomized liquid on the surface of the oil-blocking film 7; the oil-blocking film 7 and the oil-absorbing cotton 13 are arranged at intervals; the oil-absorbing cotton 13 is used to absorb the condensed liquid of the aerosol or the leaked atomized liquid, to prevent the atomized liquid or condensed liquid from sticking to the oil-blocking film 7 and affecting its air permeability, to maintain the suction resistance stability in the atomizer 100, and to improve the user experience. At the same time, since the oil-blocking film 7 and the oil-absorbing cotton 13 are arranged at intervals, the atomized liquid or condensed liquid in the oil-absorbing cotton 13 is prevented from being transmitted to the oil-blocking film 7, further improving the suction resistance stability of the atomizer 100. An empty groove 131 is arranged on the oil-absorbing cotton 13, and the empty groove 131 is located above the oil-blocking film 7, so that the air flow is smoother.

[0042] In some embodiments, see Figure 6 The oil-blocking assembly 78 is formed in the fixing seat 3 by in-mold injection molding and covers the air passage 14 to prevent the atomized liquid from leaking from the air inlet 9.

[0043] Specifically, the oil-blocking assembly 78 is formed in the fixing seat 3 by in-mold injection molding, and is welded with the fixing seat 3 to form an integral body, thereby improving the stability of the oil-blocking assembly 78 and avoiding the phenomenon of poor ventilation and atomized liquid leakage of the oil-blocking assembly 78 caused by various assembly deviations caused by assembly. In other embodiments, the oil-blocking film 7 abuts against the atomizing core 2 and blocks the atomized liquid in the air passage 14, preventing the atomized liquid droplets generated by the atomizing core 2 from leaking from the air inlet 9 during the atomization process, thereby improving the user experience.

[0044] In some embodiments, see Figure 5 The oil-blocking film 7 is made of an oleophobic material, which has oleophobic properties to prevent the oily atomized liquid from being adsorbed on the oil-blocking film 7 and affecting its ventilation effect; the oleophobic material includes one or more combinations of fiber cotton, polymer silk cotton, cloth, etc., and the oil-blocking film 7 is rigid, easy to assemble, and not easy to deform or wrinkle, thereby preventing the atomized liquid or condensation from accumulating on the oil-blocking film 7 and affecting its ventilation effect.

[0045] In some embodiments, the air permeability of the oil-blocking film 7 is 15000 m 3 / m 3 / h-35000m 3 / m 3 / h, the density of the oil-blocking film 7 is 100g / m 3 -300g / m 3 , ensuring that the oil-blocking film 7 is air-permeable but liquid cannot pass through, preventing the atomized liquid from leaking to the outer surface of the atomizer 100, and effectively improving the effect of air passing through. In other embodiments, the air permeability of the oil-blocking film 7 is 15000m 3 / m 3 / h、18000m 3 / m 3 / h、20000m 3 / m 3 / h、25000m 3 / m 3 / h、28000m 3 / m 3 / h、30000m 3 / m 3 / h、35000m3 / m 3 / h. The density of the oil-blocking film 7 is 100g / m 3 , 150g / m 3 , 180g / m 3 , 200g / m 3 , 220g / m 3 , 250g / m 3 , 280g / m 3 , 300g / m 3 .

[0046] In the following embodiment, the thickness of the oil-blocking film 7 is 0.2 mm-1.2 mm, which improves the toughness of the oil-blocking film 7 and facilitates molding. The thickness of the oil-blocking film 7 can be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, or 1.2 mm.

[0047] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
