[0043] First embodiment

[0044] FIG1 is a schematic diagram of an exploded structure of an atomizing module according to a first embodiment of the present invention; FIG2 is a schematic diagram of an exploded top view of an upper component of an atomizing module according to the first embodiment of the present invention; FIG3 is a schematic diagram of an exploded bottom view of an upper component of an atomizing module according to the first embodiment of the present invention; FIG4 is a schematic diagram of a longitudinal section of the atomizing module according to FIG1 ;

[0045] As shown in Figures 1 to 4, the atomizer module 700 of the present invention includes a lower atomizer module assembly 702 and an upper atomizer module assembly 701 disposed above the lower atomizer module assembly 702; the upper atomizer module assembly 701 includes an upper atomizer module cover 710 and an upper cover elastic body 7100; the upper cover elastic body 7100 includes an integrally formed upper cover elastic body peripheral wall 7101, an upper cover elastic body top wall 7102, an aerosol pipe interface 7104 penetrating the upper cover elastic body top wall 7102, and an aerosol pipe connecting pipe extending downward from the aerosol pipe interface 7104. 7105, and a flared portion 7106 extending downward from the bottom end of the aerosol tube connecting pipe 7105; the atomization module upper cover 710 includes an upper cover peripheral wall 712, an upper cover top wall 713, an aerosol tube connecting pipe assembly hole 715 penetrating the upper cover top wall 713, and an upper cover elastomer 7100 covering at least the upper surface of the upper cover top wall 713, a portion of the outer peripheral wall of the upper cover peripheral wall 712, and the inner peripheral wall of the aerosol tube connecting pipe assembly hole 715; the maximum cross-sectional area of ​​the internal cavity of the flared portion 7106 is greater than the cross-sectional area of ​​the aerosol tube connecting pipe assembly hole 715.

[0046] In the present invention, the flared portion 7106 refers to a structure in which the cross-sectional area of ​​the cavity inside the flared portion 7106 gradually increases from top to bottom. The flared portion 7106 facilitates the collection of aerosol and facilitates the guidance of the collected aerosol to the aerosol tube 1305, which helps improve the taste of the aerosol when the user inhales the aerosol.

[0047] Moreover, since the maximum cross-sectional area of ​​the internal cavity of the flared portion 7106 is larger than the cross-sectional area of ​​the aerosol tube connecting pipe assembly hole 715, the upper cover elastic body peripheral wall 7101, the upper cover elastic body top wall 7102, the aerosol tube interface 7104, the aerosol tube connecting pipe 7105 and the flared portion 7106 are integrally formed, thereby effectively preventing the aerosol tube connecting pipe 7105 and the flared portion 7106 from falling off, and effectively preventing the aerosol tube connecting pipe 7105 and the flared portion 7106 from falling out of the aerosol tube connecting pipe assembly hole 715.

[0048] Preferably, the atomizer module upper cover 710 includes an embedded member 7103 embedded in the upper cover elastic body 7100. The embedded member 7103 is preferably embedded within the peripheral wall of the aerosol pipe connecting pipe 7105. As shown in Figure 4, the embedded member 7103 can be an embedded member extending downward from the upper cover top wall 713. The embedded member 7103 can also be an embedded member extending from a certain part of the atomizer module upper cover 710 toward the upper cover elastic body 7100 (not shown), or it can be another type of embedded member 7103. The embedded member 7103 only needs to form a secure snap-fit ​​connection with the upper cover elastic body 7100.

[0049] As shown in Figure 2, the upper cover elastomer 7100 may further include an upper cover elastomer outer peripheral sealing strip 7108 integrally formed with the upper cover elastomer 7100, and the upper cover elastomer outer peripheral sealing strip 7108 is provided on the outer peripheral wall of the upper cover elastomer peripheral wall 7101. When the atomization module 700 and the liquid storage element 100 are assembled, the upper cover elastomer outer peripheral sealing strip 7108 can seal the gap between the atomization module 700 and the inner peripheral wall of the liquid storage element 100. The number of the upper cover elastomer outer peripheral sealing strips 7108 is preferably 2, 3 or 4. The upper cover elastomer outer peripheral sealing strip 7108 can effectively eliminate the risk of liquid leakage from the inner peripheral wall of the liquid storage element 100.

[0050] As shown in Figures 2 and 4, the upper cover elastic body 7100 includes an inner peripheral sealing strip 7109 integrally formed with the upper cover elastic body 7100. The inner peripheral sealing strip 7109 is disposed on the inner peripheral wall of the aerosol tube connecting pipe 7105. When the atomization module 700 and the liquid storage element 100 are assembled, the inner peripheral sealing strip 7109 can seal the outer peripheral wall of the aerosol tube 1305 and the aerosol module 700. The number of inner peripheral sealing strips 7109 is preferably 2, 3, or 4. The inner peripheral sealing strip 7109 can effectively eliminate the risk of liquid leakage from the aerosol tube interface 7104.

[0051] FIG5 is a schematic diagram of a structural decomposition of the lower assembly of the atomization module according to the first embodiment of the present invention; FIG6 is another schematic diagram of a structural decomposition of the lower assembly of the atomization module according to the first embodiment of the present invention.

[0052] As shown in Figures 4 to 6, the lower component 702 of the atomization module includes an atomization module base 720, an electrode 936, and a base elastomer 7200; the atomization module base 720 includes a base bottom wall 722 and a base peripheral wall 721; the base elastomer 7200 covers the inner surface of the base bottom wall 722, the inner peripheral wall of the base peripheral wall 721 and part of the outer peripheral wall of the base peripheral wall 721; the electrode 936 extends through the base bottom wall 722 and the base elastomer 7200 to the flared portion 7106.

[0053] The atomizer module 700 also includes an atomizer core 930, which is clamped between the atomizer module upper assembly 701 and the atomizer module lower assembly 702 via the upper cover elastic body 7100 and the base elastic body 7200. The electrode 936 is electrically connected to the atomizer core 930. In the present invention, as shown in FIG4 , the atomizer core 930 preferably includes an atomizer core liquid guide element 932 and a mesh heating element 931 coated on the surface of the atomizer core liquid guide element 932.

[0054] A flared portion peripheral wall groove 7107 is formed on the lower end surface of the peripheral wall of the flared portion 7106, and a base elastic body groove 7201 for accommodating the atomizer core 930 is formed on the upper surface of the base elastic body 7200 corresponding to the flared portion peripheral wall groove 7107. The flared portion peripheral wall groove 7107 and the base elastic body groove 7201 together form an elastic body through hole 7209. The atomizer core 930 passes through the elastic body through hole 7209 and is clamped by the upper cover elastic body 7100 and the base elastic body 7200.

[0055] The cross section of the elastic body through hole 7209 substantially coincides with the cross section of the atomizer core 930 .

[0056] In the present invention, the base elastomer groove 7201 is parallel to the axial direction of the atomizer core 930, and the atomizer core 930 is penetrated by an elastomer through-hole 7209. Because the cross-section of the elastomer through-hole 7209 substantially coincides with the cross-section of the atomizer core 930, the elastomer through-hole 7209 can be aligned with the radial profile of the atomizer core 930, thereby controlling the flow of liquid received by the atomizer core 930 toward the heating portion of the atomizer core 930 and controlling the flow of gas from the atomization chamber 934 to the liquid storage element 100 described below. This structure can achieve stable atomization of the liquid while preventing leakage of the liquid from the elastomer through-hole 7209.

[0057] The atomization module 700 includes an atomization chamber 934, which is formed by the atomization module upper cover 710, the flared portion 7106 and the base elastomer 7200. The portion where the electrode 936 is connected to the atomization core 930 is located in the atomization chamber 934. Preferably, the atomization chamber 934 is formed only by the flared portion 7106 and the base elastomer 7200. The atomization module 700 can be made into various sizes to meet the use requirements of different atomization devices. When the atomization module 700 is a small-sized atomization module 700, the atomization chamber 934 formed by the flared portion 7106 and the base elastomer 7200 may not be enough to accommodate the electrode 936. At this time, a cutout (not shown) can be formed on the side wall of the base elastomer groove 7201 to expand the accommodation space for the electrode 936. When the cut penetrates the side wall of the base elastic body groove 7201 , the atomization module upper cover 710 can block the cut, thereby the atomization module upper cover 710 constitutes a part of the atomization chamber 934 .

[0058] In the present invention, the upper cover elastomer 7100 and the base elastomer 7200 can be made of high-temperature resistant materials such as silicone. Silicone is more resistant to high temperatures than commonly used plastics such as PCTG or PC. When most of the wall of the atomizing chamber 934 is formed by the flared portion 7106 and the base elastomer 7200, most of the high-temperature aerosol atomized in the atomizing chamber 934 is blocked by the upper cover elastomer 7100 and the base elastomer 7200, thereby reducing the adverse effects on other components in the atomizing module 700. When the atomizing chamber 934 is completely formed by the upper cover elastomer 7100 and the base elastomer 7200, the atomizing chamber 934 has a better barrier effect on high-temperature aerosol.

[0059] In the present invention, since the flared portion 7106 is located outside the upper portion of the electrode 936, the atomized mist can be restricted from diffusing to the left and right sides of the atomization module 700, so that the mist can enter the aerosol tube 1305 described later along the flared portion 7106.

[0060] Preferably, the upper portion of the electrode 936 includes an electrode connection base plate 9361, an electrode connection fork 9362 disposed on one side of the electrode connection base plate 9361 and perpendicular to the electrode connection base plate 9361, and an electrode bend 9363 disposed on the other side of the electrode connection base plate 9361 and perpendicular to the electrode connection base plate 9361. The electrode fork 9361 passes through the base bottom wall 722 and the base elastic body 7200 to support the atomizer core 930. The electrode bend 9363 is embedded in the base bottom wall 722, and the electrode connection base plate 9361 is attached to the bottom surface of the base bottom wall 722. The electrode structure can be firmly supported by the base bottom wall 722 while facilitating contact-type electrical connection with an external atomizer host. In the present invention, the electrode 936 includes the electrode fork 9361, and the atomizer core 930 can be conveniently fixed in the electrode fork 9361 to form an electrical connection without the need for conventional welding installation processes, thereby reducing costs and improving assembly efficiency.

[0061] The lower portion of the electrode 936 can also be configured as a column or tube and extend beyond the bottom surface of the base bottom wall 722. This electrode structure can facilitate plug-in electrical connection with an external atomizing host.

[0062] Preferably, the electrode 936 is plated with gold, which can enhance the electrical connection and corrosion resistance of the electrode 936.

[0063] As shown in Figures 4 and 5, the base elastic body 7200 includes a base elastic peripheral sealing strip 7203 integrally formed with the base elastic body 7200, and the base elastic peripheral sealing strip 7203 is provided on the outer peripheral wall of the base elastic body 7200. The base elastic peripheral sealing strip 7203 can seal the gap between the inner peripheral wall of the upper cover peripheral wall 712 and the outer peripheral wall of the base elastic body 7200, thereby eliminating the risk of liquid leakage from the atomization module 700.

[0064] In the present invention, the upper cover elastomer 7100 and the base elastomer 7200 are integrally formed with multiple sealing strips, which can avoid the use of soft and small sealing rings in the atomization module 700. Therefore, the atomization module 700 according to the present invention can greatly reduce the assembly difficulty of the product and the risk of liquid leakage while reducing the number of parts.

[0065] The base elastomer 7200 includes a base elastomer inner cavity 7204, which is formed by being concave from the upper surface of the base elastomer 7200 and is located directly below the flared portion 7106. The base elastomer inner cavity 7204 can store a small amount of liquid, thereby improving the anti-leakage capability of the aerosol bomb. The projection of the flared portion 7106 on the upper surface of the base elastomer 7200 includes the opening of the base elastomer inner cavity 7204 on the upper surface of the base elastomer 7200, that is, the area of ​​the opening of the base elastomer inner cavity 7204 on the upper surface of the base elastomer 7200 is smaller than the projected area of ​​the flared portion 7106 on the upper surface of the base elastomer 7200. Thus, the base elastomer inner cavity 7204 can also constitute a part of the atomizing chamber 934, thereby expanding the volume of the atomizing chamber 934.

[0066] The base elastic body 7200 includes a base elastic body air inlet pipe 7205. Preferably, the base elastic body air inlet pipe 7205 is formed by extending from the bottom surface of the base elastic body 7200 into the base elastic body inner cavity 7204.

[0067] A base air inlet 723 is formed on the base bottom wall 722 and passes through the base bottom wall 722. The base elastomer air inlet pipe 7205 is directly opposite to the base air inlet 723. The external air flow enters the base elastomer air inlet pipe 7205 from the base air inlet 723, and then the gas is transported to the atomization chamber 934 through the base elastomer air inlet pipe 7205.

[0068] Preferably, one end of the base elastomer air inlet pipe 7205 facing the atomizer core 930 has an air inlet pipe bottom wall 7202, and a plurality of air guide holes 7206 are provided on the air inlet pipe bottom wall 7202, or a plurality of air inlet holes 7206 are provided on the side wall of the base elastomer air inlet pipe 7205, and external gas enters the atomization chamber 934 through the air inlet holes 7206.

[0069] In the present invention, the upper cover elastic body 7100 and the base elastic body 7200 are preferably made of a material that is resistant to high temperatures and has good biosafety, such as silicone.

[0070] In the manufacturing method of the atomization module according to the present invention, preferably, it includes: the atomization module upper component 701 is made by partially covering the atomization module upper cover 710 with a first liquid silicone and curing it, and the first liquid silicone is partially cured to form an upper cover elastomer 7100.

[0071] Preferably, the atomization module lower component 702 is made by partially covering the atomization module base 720 of the embedded electrode 936 with the second liquid silicone and curing it, and the second liquid silicone partially forms the base elastic body 7200 after curing.

[0072] In this way, the risk of liquid leakage from the connection between the electrode 936 and the atomizer module base 720 can be effectively eliminated. Of course, the atomizer module lower assembly 702 can also be assembled from a pre-formed silicone base elastomer 7200 and the atomizer module base 720 with the electrode 936 embedded in it.

[0073] As shown in Figure 2, in the present invention, the upper cover 710 of the atomizer module includes an upper cover liquid guide hole 714 that passes through the upper cover top wall 713, and an upper cover fluid channel 711 that connects the upper cover liquid guide hole 714 and the atomizer core 930. The upper cover liquid guide hole 714 is used to transfer liquid to the atomizer core 930. The upper cover elastic body 7100 is provided with an upper cover elastic body liquid guide hole 7110 at a position opposite to the upper cover liquid guide hole 714, which is used to transfer liquid to the upper cover liquid guide hole 714.

[0074] As shown in Figures 3 and 4, the upper cover 710 of the atomizer module may include an upper cover fluid channel 711 connecting the upper cover liquid guide hole 714 and the atomizer core 930. The upper cover fluid channel 711 may be a hollow tube extending from the upper cover liquid guide hole 714 toward the atomizer core 930. The inner circumferential wall of the hollow tube may be axially provided with a plurality of capillary grooves, and the lower end of the hollow tube may contact the atomizer core 930. The upper cover fluid channel 711 may be integrally formed with the upper cover 710 of the atomizer module.

[0075] Figure 7 is a schematic structural diagram of an aerosol cartridge 800 according to a first embodiment of the present invention. As shown in Figure 7 , the aerosol cartridge 800 includes an atomization module 700 and a liquid storage element 100 according to the present invention, and the liquid storage element 100 is in communication with the atomization module 700.

[0076] The liquid storage element 100 includes an aerosol bomb housing 810 , a liquid storage portion 101 disposed in the aerosol bomb housing 810 , and an aerosol tube 1305 extending from the top wall of the aerosol bomb housing 810 into the liquid storage portion 101 .

[0077] When the atomization module 700 and the liquid storage element 100 are assembled together, the upper cover elastic body 7100 blocks the lower opening of the liquid storage part 101, and the aerosol tube 1305 is inserted into the aerosol tube interface 7104 and the aerosol tube connecting pipe 7105. The inner peripheral sealing strip 7109 of the aerosol tube connecting pipe of the upper cover elastic body 7100 seals the outer peripheral wall of the lower end of the aerosol tube 1305, and the upper cover elastic outer peripheral sealing strip 7108 seals the inner peripheral wall of the aerosol bomb housing 810. The liquid in the liquid storage part 101 enters the atomization module 700 through the upper cover elastic body liquid guide hole 7110, the upper cover liquid guide hole 714 and the upper cover fluid channel 711, and the liquid is transferred to the atomization core 930. The aerosol atomized in the atomization chamber 934 escapes through the aerosol tube 1305.

[0078] The atomization module 700 can be assembled from the atomization module upper component 701, the atomization core 930 and the atomization module lower component 702. The atomization module 700 and the liquid storage element 100 can be pressed together to form the aerosol cartridge 800. Therefore, the atomization module 700 according to the present invention can conveniently and efficiently assemble the aerosol cartridge 800.
