The shell is also provided with an atomization channel and a liquid storage chamber for supplying atomized liquid to the atomizer core (the side wall of the atomization channel has an oil inlet hole connected to the liquid storage chamber, the atomizer core is arranged in the atomization channel and located at the oil inlet hole, and the oil inlet hole is used to guide the atomized liquid in the liquid storage chamber to the oil guide body), the oil guide body is used to guide the atomized liquid supplied by the liquid storage chamber to the heating element, and the heating element is used to heat the atomized liquid supplied by the atomization liquid storage chamber to form an inhalable aerosol leading to the atomization channel. Compared with traditional cigarettes, the electronic atomizer device has the advantages of no tar, no ash, no open flame, etc., which can effectively avoid the various harmful substances produced by traditional cigarettes when they are ignited.
[0003] Among them, the assembled electronic atomization device needs to inject atomizing liquid into the liquid storage chamber. During this process and the subsequent storage and transportation links, since the atomizing liquid in the liquid storage chamber can contact the oil guide body through the oil inlet hole, there is a situation where the atomizing liquid seeps out from the surface of the oil guide body and forms a leakage that flows into the atomization channel. Therefore, there is a problem that the leakage flows to the electronic components, causing damage to electronic components such as circuit boards or microphones and making the electronic atomization device unable to work normally.

[0029] Reference Figures 1 to 4 According to an embodiment of the present application, the electronic atomization device includes an oil cup 100, an atomization core 200 and an atomization bracket 300. The atomization bracket 300 is at least partially located inside the oil cup 100. The atomization bracket 300 and the inner wall of the oil cup 100 enclose a liquid storage chamber 400 for storing atomized liquid. An atomization channel 311 is formed inside the atomization bracket 300. The atomization core 200 is at least partially arranged in the atomization channel 311 and is fluidly connected to the liquid storage chamber 400. The atomization core 200 includes an oil guide body and a heating body. The oil guide body of the atomization core 200 is used to guide the atomized liquid in the liquid storage chamber 400 to the heating body of the atomization core 200. The heating body of the atomization core 200 is used to heat the atomized liquid flowing toward the atomization core 200 to form an inhalable aerosol leading to the atomization channel 311.
[0030] Among them, the atomizer bracket 300 includes a bracket body 310 and a sealing coating 320, an atomization channel 311 is formed inside the bracket body 310, and a side wall of the atomization channel 311 has an oil inlet hole 312 connected to the liquid storage chamber 400, and the atomizer core 200 is fluidically connected to the liquid storage chamber 400 through the oil inlet hole 312. The sealing coating 320 is arranged at the oil inlet hole 312 and is used to seal the oil inlet hole 312. The sealing coating 320 is a structure that is fluid-impermeable and decomposable by heating.
[0031] Since a fluid-impermeable sealing coating 320 is provided at the oil inlet hole 312 of the bracket body 310 to block the oil inlet hole 312, before the electronic atomization device is used, the sealing coating 320 can limit the atomized liquid in the liquid storage chamber 400 from flowing to the atomization core 200 through the oil inlet hole 312, thereby preventing the atomized liquid in the liquid storage chamber 400 from seeping out through the surface of the oil guide body of the atomization core 200. Among them, the sealing coating 320 is a structure that can be decomposed by heating. When the user uses the electronic atomization device for the first time, the heating element of the atomization core 200 used to heat the atomized liquid supplied by the atomization liquid storage chamber 400 can heat and decompose the sealing coating 320 to remove the sealing coating 320 from blocking the oil inlet hole 312, so that the electronic atomization device can be used normally.
[0032] It should be noted that in some of the embodiments, the decomposition temperature of the sealing coating 320 is lower than a preset value. When the user uses the electronic atomization device for the first time, the sealing coating 320 can be quickly heated and decomposed by the heating element of the atomization core 200, thereby preventing the sealing coating 320 from obstructing the atomized liquid in the liquid storage chamber 400 from flowing to the oil guide body of the atomization core 200 through the oil inlet hole 312, that is, the sealing coating 320 can quickly release the blockage of the oil inlet hole 312, which is conducive to preventing the heating element of the atomization core 200 from dry burning. Specifically, the decomposition temperature of the sealing coating 320 is lower than the atomization temperature of the atomization core 200 to heat the atomized liquid into atomized liquid. As an example, the atomization temperature of the atomized liquid can be 2 to 3 times the decomposition temperature of the sealing coating 320.
[0033] It should be noted that, in some of the embodiments, the decomposition temperature of the sealing coating 320 is 60°C to 120°C. Specifically, the decomposition temperature of the sealing coating 320 can be 60°C, 120°C, 100°C, or other values within the above numerical range, which are not limited here.
[0034] It should be noted that in some of the embodiments, the thickness of the sealing coating 320 is less than or equal to 0.5 mm, so that the sealing coating 320 can be better adhered to the bracket body 310. If the thickness of the sealing coating 320 is greater than 0.5 mm, it will not only increase the processing cycle of the sealing coating 320, but also increase the difficulty of controlling the dimensional process, and may increase the difficulty of assembling related components.
[0035] It should be noted that in some of the embodiments, the stent body 310 is a tubular structure, and the lumen inside the stent body 310 forms the above-mentioned atomization channel 311. The tubular structure refers to a hollow columnar structure. Compared with the stent body 310 with a special-shaped structure, the stent body 310 with a tubular structure is simple in structure and easy to process, and is also conducive to reducing the difficulty of assembling the stent body 310. Specifically, the outer contour shape of the cross section of the stent body 310 can be circular, rectangular or other polygonal, which is not limited here.
[0036] In addition, the outer contour shape of the cross section of the atomization channel 311 can be circular, rectangular or other polygonal, which is not limited here.
[0037] Reference Figure 2 and Figure 4 In some of the embodiments, the sealing coating 320 is disposed on the outer peripheral surface of the bracket body 310, which facilitates the processing of the sealing coating 320 and helps to improve the processing efficiency.
[0038] It should be noted that, in some other embodiments, the sealing coating 320 may also be disposed on the inner side wall of the bracket body 310, which is not limited here. The sealing coating 320 is disposed on the inner side wall of the bracket body 310 so that the sealing coating 320 is closer to the heating element of the atomizer core 200, so that when the user uses the electronic atomization device for the first time, the heating element of the atomizer core 200 can quickly heat and decompose the sealing coating 320.
[0039] It should be noted that in some other embodiments, a sealing coating 320 is provided on the outer circumferential surface and the inner side wall of the bracket body 310 at the position corresponding to the oil inlet hole 312, which is not limited here. Among them, the sealing coating 320 for blocking the oil inlet hole 312 is provided on the outer circumferential surface and the inner side wall of the bracket body 310, which is conducive to improving the sealing effect of the sealing coating 320.
[0040] It should be noted that, in some other embodiments, the sealing coating 320 may also be partially or completely located in the oil inlet hole 312 and bonded to the inner wall of the oil inlet hole 312, which is not limited here.
[0041] It should be noted that in some of the embodiments, the bracket body 310 is a hard structure, so that the bracket body 310 has a certain structural strength, which can prevent the atomization channel 311 from narrowing or closing due to the deformation of the bracket body 310. In addition, the hard structure of the bracket body 310 is easy to fix, which helps to reduce the difficulty of assembling the atomization bracket 300.
[0042] It should be noted that, in some of the embodiments, the bracket body 310 is made of metal material, such as stainless steel, so that the bracket body 310 has higher reliability and stability.
[0043] It should be noted that, in some other embodiments, the bracket body 310 may also be made of high temperature resistant hard plastic, which is not limited here.
[0044] It should be noted that in some other embodiments, the bracket body 310 may also be a flexible structure, which is not limited here. The bracket body 310 with a flexible structure can be deformed during assembly, which can not only better adapt to a more complex installation environment, but also reduce the requirements for assembly accuracy when assembling the bracket body 310.
[0045] It should be noted that, in some other embodiments, the bracket body 310 may also be integrally formed with the oil cup 100 , that is, there is no need to separately process the atomizing bracket 300 and assemble it into the oil cup 100 , which is not limited here.
[0046] It should be noted that in some embodiments, the cross-sectional area of the oil inlet hole 312 is less than or equal to 50 mm. 2As an example, the cross-sectional area of the oil inlet hole 312 may be 40 mm 2 , 30mm 2 , 20mm 2 or 10mm 2 , so that the area of the sealing coating 320 to be applied does not need to be too large, which is beneficial to prevent the applied sealing coating 320 from being damaged or falling off, thereby improving the reliability and stability of the sealing coating 320.
[0047] It should be noted that, in some of the embodiments, the number of the oil inlet holes 312 on the atomizer bracket 300 may be one or more, wherein the cross-section of the oil inlet hole 312 may be a regular shape such as a circle, a semicircle, a polygon (such as a rectangle), or an irregular shape. As an example, taking the cross-section of the oil inlet hole 312 as a circle, the diameter of the oil inlet hole 312 may be less than or equal to 5 mm, such as 4 mm, 3 mm, or 2 mm. Taking the cross-section of the oil inlet hole 312 as a rectangle as an example, the length and width of the oil inlet hole 312 are 6 mm×5 mm, 5 mm×4 mm, 3 mm×2 mm, 6 mm×2 mm, etc.
[0048] It should be noted that in some of the embodiments, the sealing coating 320 is made of PVB (polyvinyl butyral), which is not easily soluble in water and is easy to form a film. The sealing coating 320 made of PVB can be decomposed when heated to 60°C to 120°C. In addition, PVB is a food-grade material, which is non-toxic, harmless and odorless, and will not affect the user's health as well as the taste and experience during smoking.
[0049] It should be noted that, in some other embodiments, the sealing coating 320 may also be made of sodium alginate, which is not limited here.
[0050] It should be noted that, in some embodiments, the preparation process of the atomizing bracket 300 is as follows:
[0051] One of the PVB powder and the sodium alginate powder is mixed with ethanol to prepare a coating material that can be decomposed by heating, wherein the mass ratio of the powder to the ethanol is n:5, wherein 1≤n≤3;
[0052] Providing a support body 310, applying the configured coating material to the oil inlet hole 312 of the support body 310 to form a sealing coating 320;
[0053] The applied sealing coating 320 is dried.
[0054] Specifically, ethanol has high volatility, so that the coating material coated on the stent body 310 can be dried quickly in a short time, which is beneficial to improving the processing efficiency of the sealing coating 320. The mass ratio of the powder to ethanol can be 1:5, 2:5, 3:5, or other ratios within the above ratio range, which is not limited here.
[0055] The applied sealing coating 320 may be left standing to dry. Of course, the applied sealing coating 320 may also be dried by baking, which is not limited here.
[0056] In addition, the above-mentioned coating material can be configured with an ethanol solution with a concentration greater than or equal to 95%. When the above-mentioned coating material is configured with an ethanol solution with a concentration greater than or equal to 95%, due to the low water content in the ethanol solution, the drying time of the coating material coated on the bracket body 310 can be further shortened, which is beneficial to further improve the processing efficiency of the sealing coating 320.
[0057] It should be noted that, in some of the embodiments, anhydrous ethanol may be used to prepare the above-mentioned coating material. Of course, absolute ethanol may also be used to prepare the above-mentioned coating material, which is not limited here.
