[0030] Figures 1 to 6 are drawings of the present invention.

[0031] This embodiment provides a leak-proof atomizing device 10, see Figures 1 to 6 , including a base 11, an oil cup 12 sealedly connected to the base 11, a vent pipe 13 arranged on the inner side of the oil cup 12, and a heating element 14. A liquid storage tank 15 is formed between the base 11 and the oil cup 12. An inner sleeve 16 is fixed to the side of the base 11 facing the liquid storage tank 15, and the heating element 14 is arranged on the inner side of the inner sleeve 16. One end of the vent pipe 13 is sleeved on the outer side of the inner sleeve 16, and the vent pipe 13 has axial movement relative to the inner sleeve 16, so that the liquid storage tank 15 and the heating element 14 are connected or isolated.

[0032] The vent pipe 13 has axial movement relative to the inner sleeve 16, so that the vent pipe 13 has the function of isolating the liquid storage tank 15 from the inner sleeve 16, preventing the tobacco oil in the liquid storage tank 15 from flowing out through the heating element 14 and the vent pipe 13. In this way, the liquid storage tank 15 is in a completely sealed state, completely eliminating the risk of oil leakage during long-term storage, transportation or high-altitude and high-pressure environments of the atomizer 10. It also prevents the tobacco oil in the liquid storage tank 15 from contacting the outside air, preventing the liquid from deteriorating, changing taste or volatilizing.

[0033] The inner sleeve 16 is provided with a first oil inlet hole 161 connected to the heating element 14. The ventilation pipe 13 is provided with a second oil inlet hole 131 connected to the first oil inlet hole 161. When the ventilation pipe 13 is pushed inward into place, the first oil inlet hole 161 is connected to the second oil inlet hole 131, so that the heating element 14 is connected to the liquid storage tank 15, and the smoke oil can enter the heating element 14. After the ventilation pipe 13 is pulled outward into place, the first oil inlet hole 161 and the second oil inlet hole 131 are staggered with each other, so that the ventilation pipe 13 isolates the heating element 14 from the liquid storage tank 15 to avoid oil leakage. At the same time, the smoke oil in the liquid storage tank 15 is in a completely isolated state from the ceramic heating element, preventing the oil absorption micropores of the ceramic heating element from being blocked by liquid sediment during long-term storage, which is more likely to burn and change taste, thereby reducing the taste.

[0034] The first oil inlet hole 161 and the second oil inlet hole 131 are both arranged close to the base 11 , so that the tobacco oil in the liquid storage tank 15 can all enter the heating element 14 .

[0035] Preferably, the heating element 14 is a ceramic heating element.

[0036] A first sealing member 17 is provided at one end of the liquid storage bin 15 close to the base 11. The first sealing member 17 is sleeved on the outside of the vent pipe 13. The first sealing member 17 is used to seal the liquid storage bin 15 with the base 11, the vent pipe 13 and the inner sleeve 16. The first sealing member 17 is always sealed with the vent pipe 13, regardless of whether the vent pipe 13 moves to the isolation position or the connection position.

[0037] Preferably, the first sealing member 17 is provided with a protrusion 171, and the protrusion 171 is provided with a third oil inlet hole 172. The protrusion 171 surrounds the outside of the ventilation pipe 13, and the third oil inlet hole 172 is arranged at the same horizontal plane as the first oil inlet hole 161. In the isolated state, the ventilation pipe 13 is pulled out for a distance, and the ventilation pipe 13 blocks the third oil inlet hole 172 from the first oil inlet hole 161, so that the smoke oil in the liquid storage tank 15 cannot flow out; in the connected state, the ventilation pipe 13 is pushed forward for a distance, so that the third oil inlet hole 172 is connected with the first oil inlet hole 161 through the second oil inlet hole 131, so that the smoke oil in the liquid storage tank 15 flows out to the heating element 14.

[0038] In other embodiments, the gap between the third oil inlet hole 172 and the first oil inlet hole 161 can be controlled by adjusting the position of the ventilation pipe 13, thereby adjusting the amount of smoke oil entering the heating element 14 to control the amount of atomized smoke.

[0039] A second sealing member 18 is provided between the inner sleeve 16 and the inner wall of the vent pipe 13 to prevent oil leakage between the inner sleeve 16 and the vent pipe 13 .

[0040] A third sealing member 19 is provided between the air outlet end of the vent pipe 13 and the oil cup 12 , and is used to seal the connection between the vent pipe 13 and the oil cup 12 to prevent oil leakage from the liquid storage tank 15 .

[0041] The air outlet end of the vent pipe 13 is provided with a push cover 101, so that the vent pipe 13 can be pushed in or pulled out more conveniently. The vent pipe 13 extends to the outside of the oil cup 12, and the push cover 101 is provided at the outer end of the vent pipe 13. When the vent pipe 13 is pressed into the oil cup 12, a concave cavity 102 for accommodating the push cover 101 is provided on the oil cup 12, so that the entire push cover 101 can be accommodated in the concave cavity 102.

[0042] The base 11 is provided with a first air inlet 111. The first air inlet 111 is connected to the heating element 14 and the vent pipe 13. The heating element 14 is provided with a central hole 141, and the first air inlet 111 is connected to the vent pipe 13 through the central hole 141, serving as an air inlet passage of the atomizing device. When working, the heating element 14 allows the atomized liquid to flow out of the vent pipe 13.

[0043] An electronic cigarette with a leak-proof atomizing device, see Figures 1 to 6 , including a power socket 20 and the above-mentioned atomization device 10. The power socket 20 is connected to the atomization device 10, wherein the power socket 20 and the atomization device 10 can be connected in various ways, such as threaded connection, magnetic connection of magnets, etc.

[0044] The power socket 20 is provided with a second air inlet 21 connected to the first air inlet 111. When the electronic cigarette is working, air flows in from the second air inlet 21, and then reaches the central hole 141 of the heating element 14 through the first air inlet 111, and then the atomized liquid of the heating element 14 flows out from the ventilation pipe 13.

[0045] The atomizing device 10 is provided with a dust cover 22 at the air outlet end, which effectively prevents the suction nozzle of the oil cup 12 from being exposed to the outside, has the characteristics of dustproof, dirt-proof, and child-proof, achieving the purpose of health, safety, and hygiene.

[0046] The power socket 20 includes a housing 23 and a battery 24 disposed inside the housing 23. The second air inlet 21 is formed between the housing 23 and the battery 24. An integrated control switch 26 is provided at the air inlet end of the second air inlet 21. When inhaling, the integrated control switch 26 is turned on, and the atomizing device 10 is powered on and works.

[0047] Preferably, the air inlet end of the second air inlet passage 21 is arranged at an end of the housing 23 that is farther from the atomizing device 10 , and a fourth sealing member 25 is further provided at the air inlet end of the second air inlet passage 21 .

[0048] In other embodiments, the base 11 is provided with a magnet and a conductor. The conductor is electrically connected to the heating element 14 and is a positive conductor and a negative conductor. The conductor is electrically connected to the battery. The magnet is used to detachably connect the atomization device 10 to the power supply base 20.

[0049] Compared with the prior art, the vent pipe 13 of the oil cup 12 of the present invention can move axially, so that the liquid storage tank 15 and the heating element 14 are blocked or connected through the vent pipe 13. When not in use, the vent pipe 13 extends outward, and the first oil inlet hole 161 is separated from the second oil inlet hole 131 to prevent the oil in the liquid storage tank 15 from leaking; when in use, the vent pipe 13 is pressed to connect the first oil inlet hole 161 with the second oil inlet hole 131, and the oil in the liquid storage tank 15 flows to the heating element 14.

[0050] The present invention prevents the smoke oil in the liquid storage bin 15 from flowing out of the vent pipe 13, and pushes the vent pipe 13 forward when in use. This design realizes that the liquid storage bin 15 is in a completely sealed state, eliminating the risk of oil leakage of the atomizer 10 during long-term storage, transportation, or high-altitude and high-pressure environments, and avoiding contact with the outside air to prevent the liquid from deteriorating, changing taste, or volatilizing. In addition, the smoke oil in the liquid storage bin 15 is in a completely isolated state from the ceramic heating element, preventing the oil absorption micropores of the ceramic heating element from being blocked by smoke oil sediment during long-term storage, avoiding burning or changing taste, and enhancing the taste.

[0051] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
