[0027] Reference Figures 1 to 3 The utility model proposes a double-layer leak-proof atomizer assembly 100, which includes an outer shell 110, an inner tube 120, an atomizer core 130 and a sealing member 140. The outer shell 110 is hollow and has a receiving chamber 112. The bottom of the receiving chamber 112 has a first opening 113. The inner tube 120 is installed in the receiving chamber 112. The bottom of the inner tube 120 is provided with a second opening 121. The sealing member 140 and the inner tube 120 enclose an oil storage chamber 170. The atomizer core 130 is fixed on the sealing member 140 and installed in the oil storage chamber 170. The sealing member 140 is provided with a sealing flange 141 and a sealing step 142. The sealing flange 141 seals the second opening 121, and the sealing step 142 seals the first opening 113.

[0028] Among them, the second opening 121 is set at the bottom of the inner tube 120, the sealing member 140 is sealed at the second opening 121, the sealing member 140 and the inner tube 120 enclose an oil storage chamber 170, an airflow tube 190 is installed in the middle of the oil storage chamber 170, the atomization core 130 is installed on the airflow tube 190 and is coaxially arranged with the airflow tube 190, an oil storage cotton 171 is arranged in the oil storage chamber 170, and the atomization core 130 is connected with the oil storage chamber 170, and is used to heat and atomize the tobacco oil in the oil storage chamber 170 to generate aerosol for the user to inhale.

[0029] Specifically, the inner tube 120 is installed in the outer shell 110, and the seal 140 is first sealed with the inner tube 120, and then inserted into the outer shell 110 together with the inner tube 120. During the process of installing the inner tube 120 in the outer shell 110, the sealing step 142 seals the first opening 113, that is, the seal 140 is sealed with the bottom of the outer shell 110.

[0030] It is worth noting that the seal 140 is made of silicone material, and includes a sealing flange 141 and a sealing step 142. The sealing flange 141 is used to seal the inner tube 120, and the sealing step 142 is used to seal the outer shell 110. Under the joint action of the sealing flange 141 and the sealing step 142, the phenomenon of smoke oil leakage is avoided. In order to improve the sealing performance of the sealing flange 141 and the inner tube 120, two sealing ribs are provided on the circumference of the sealing flange 141 to improve the sealing effect of the seal 140.

[0031] After adopting the above technical solution, the seal 140 is arranged in the double-layer leak-proof atomizer assembly 100, and the inner tube 120 and the outer shell 110 are sealed and connected by the sealing flange 141 and the sealing boss 152 on the seal 140, respectively, so as to achieve a double sealing effect in the double-layer leak-proof atomizer assembly 100. Under the joint action of the sealing flange 141 and the sealing step 142, the phenomenon of the oil in the oil storage chamber 170 leaking from the matching gap is reduced, and the oil is prevented from leaking to the outside of the atomizer assembly to affect the normal use of the user.

[0032] In an optional embodiment, the shape of the first opening 113 is inconsistent with the shape of the second opening 121. That is, the shape of the cross section of the outer shell 110 is inconsistent with the shape of the cross section of the inner tube 120, and there is a gap between a part of the inner tube 120 and the outer shell 110. The cross section of the inner tube 120 is surrounded by arc segments, which makes it easy for the sealing flange 141 to match with the inner tube 120, thereby improving the sealing effect between the sealing flange 141 and the inner tube 120. In this embodiment, the shape of the cross section of the outer shell 110 is inconsistent with the shape of the cross section of the inner tube 120, so as to avoid the phenomenon that the inner tube 120 and the outer shell 110 are not tightly matched at the same place. For example, when the inner tube 120 has a matching gap with the sealing flange 141 at the left end point, the outer shell 110 is often tightly matched between the sealing step 142 at the left end point, thereby reducing the possibility of the smoke oil leaking to the outside of the atomization component.

[0033] In this embodiment, the cross section of the inner tube 120 is elliptical, which facilitates the matching of the sealing flange 141 with the second opening 121, improves the sealing performance between the sealing member 140 and the inner tube 120, and reduces the possibility of leakage of the smoke oil. It is understandable that the cross section of the inner tube 120 can also be circular.

[0034] In an optional embodiment, the top of the inner tube 120 is provided with a third opening 122, and the double-layer leak-proof atomizer assembly 100 further includes a sealing plug 150, which closes the third opening 122, and is provided with an air vent 151, which is connected to the oil storage chamber 170. In this embodiment, the openings at the opposite ends of the inner tube 120 are provided, which is convenient for the production of the inner tube 120 and saves the production cost of the inner tube 120. The third opening 122 of the inner tube 120 is blocked by the sealing plug 150, which is convenient for filling the oil storage chamber 170. In this embodiment, the air vent 151 is connected to the outside world, so that the pressure in the oil storage chamber 170 is consistent with that in the outside world, and it is easy to inject smoke oil into the oil storage chamber 170. If the air hole 151 is not opened on the sealing plug 150, the air at the top of the inner tube 120 is easily compressed during the process of injecting oil into the oil storage chamber 170 from the bottom, affecting the normal injection of the double-layer leak-proof atomizing assembly 100.

[0035] In an optional embodiment, the housing 110 is configured with a suction nozzle 111, and the sealing plug 150 is provided with a sealing boss 152, and the sealing boss 152 is sealed and connected to the inner side wall of the suction nozzle 111. In this embodiment, when the sealing plug 150 seals the third opening 122, the sealing plug 150 is also sealed and connected to the inner side wall of the suction nozzle 111, that is, the sealing plug 150 is sealed and connected to the inner tube 120 and the housing 110 at the same time, achieving a double-layer sealing effect, thereby preventing the oil storage chamber 170 from leaking tobacco oil.

[0036] In this embodiment, the sealing boss 152 is provided with a groove, and the groove is filled with oil-absorbing cotton 160. The groove is arranged away from the sealing member 140, and the oil-absorbing cotton 160 is installed in the groove. A through hole is arranged in the middle of the oil-absorbing cotton 160, and the through hole is arranged coaxially with the suction nozzle 111. The condensate generated in the suction nozzle 111 is absorbed by the oil-absorbing cotton 160 when it flows downward under the action of gravity, so as to avoid the condensate from contacting the atomization core 130 and causing oil frying, thereby improving the use experience of the double-layer leak-proof atomization assembly 100.

[0037] In this embodiment, the oil storage cavity 170 is provided with oil storage cotton 171, and the sealing boss 152 is further provided with a top platform 153 on the side facing the sealing member 140, and the top platform 153 abuts against the oil storage cotton 171. The oil storage cavity 170 is filled with oil storage cotton 171, and the smoke oil in the oil storage cavity 170 is absorbed by the oil storage cotton 171, and the oil storage cotton 171 is used to prevent the smoke oil in the oil storage cavity 170 from shaking. After absorbing the smoke oil, the oil storage cotton 171 expands upward, and the top platform 153 abuts against the oil absorption cotton 160 to prevent the oil absorption cotton 160 from being close to the sealing plug 150, and to prevent the smoke oil from flowing out of the air vent 151.

[0038] In an optional embodiment, the double-layer leak-proof atomization assembly 100 further includes an airflow tube 190, the airflow tube 190 is fixed to the seal 140, the atomization core 130 is coaxially arranged with the airflow tube 190, and the seal 140 is provided with a convex ring 143 at the position where it cooperates with the airflow tube 190, and the convex ring 143 is circumferentially sealed and connected with the airflow tube 190. The convex ring 143 is wedge-shaped, and the convex ring 143 increases the matching length of the seal 140 and the airflow tube 190, thereby improving the sealing performance of the seal 140 and the airflow tube 190, and avoiding oil leakage.

[0039] In an optional embodiment, the double-layer leak-proof atomizer assembly 100 further includes a base 180, which is connected to the seal 140, and the base 180 is snap-connected to the housing 110. The seal 140 is coated on the base 180, and a snap-on buckle position is provided on the base 180. The housing 110 is provided with a snap-on hole at a position corresponding to the snap-on buckle position, and the snap-on buckle position cooperates with the snap-on hole to make the base 180 and the housing 110 tightly connected together. Among them, the base 180 is made of plastic material, and a support column is provided on the base 180. The sealing step 142 is located at the periphery of the support column to improve the tightness of the connection between the sealing step 142 and the housing 110.
