[0026] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0027] Please refer to Figure 1 , Figure 2 and Figure 4As shown, an oil supply structure of an electronic cigarette cartridge comprises an electronic cigarette consisting of a cigarette device body 1, an oil storage tank 2 and a cigarette cartridge 3. An oil supply mechanism for supplying oil to the cigarette cartridge 3 is arranged between the cigarette cartridge 3 and the oil storage tank 2. A mounting bracket 5 is also arranged on the inner side of the cigarette device body 1. Two connecting tubes 7 and a fixing rod 8 are also arranged on the bottom of the mounting bracket 5. A button for controlling the operation of the electronic cigarette and a charging hole for charging and replenishing the electronic cigarette are also arranged on the outer side of the cigarette device body 1, so that the charging hole can supply power to the atomizing core 33, thereby realizing the operation of the atomizing core 33. There are two oil storage tanks 2. The tops of the two oil storage tanks 2 are fixedly connected with mounting tubes. The two mounting tubes are respectively connected to the two connecting tubes 7, and the two connecting tubes 7 are connected to the two connecting tubes 7. The connecting pipes 7 are respectively distributed on the inner sides of the two mounting tubes, and one end of the fixing rod 8 away from the mounting bracket 5 is mounted on the inner bottom of the smoking device body 1. The inner tops of the two connecting pipes 7 are provided with oil-sealing silicone 71, so that when the cigarette cartridge 3 is connected to the oil storage tank 2, the dedicated oil inlet 35 at the bottom of the cigarette cartridge 3 is aligned with the connecting pipe 7 of the oil storage tank 2, and the oil-sealing silicone 71 of the oil storage tank 2 automatically opens to realize the continuous oil supply from the oil storage tank 2 to the cigarette cartridge 3. When the oil storage tank 2 is removed and inverted, the oil pressure pushes the oil-sealing silicone 71 to rebound and seal the connecting pipe 7 to ensure that there is no oil leakage when removed. The specifications and sizes of the two oil-sealing silicone 71 are the same, so that the two oil storage tanks 2 can greatly increase the oil storage capacity of the electronic cigarette, thereby greatly increasing the use time of the electronic cigarette.

[0028] Please refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the oil supply mechanism includes a smoke outlet 31 with an inhalation port at the top of the inner side of the smoke cartridge 3, an insertion port 32 opened at the bottom of the inner side of the smoke cartridge 3, and two electric contacts 36 and an air inlet 37 arranged at the bottom of the smoke cartridge 3. An atomizer core 33 is arranged on the inner side of the smoke outlet 31, so that the atomizer core 33 can atomize the smoke oil entering the smoke outlet 31, so as to enable the user to inhale. An oil guide column 34 is fixedly connected to the inner side of the insertion port 32, so that the oil guide column 34 will be inserted into the oil sealing silicone 71 when in use. At this time, the connecting tube 7 in The smoke oil will enter the oil inlet 35 through the oil storage tank 2 and then enter the smoke cartridge 3. The oil inlet 35 is arranged on the inner side of the insertion port 32. The oil inlet 35 can facilitate the smoke oil in the oil storage tank 2 to enter the smoke cartridge 3. A pressure relief groove 38 is also arranged in the insertion port 32, so that the pressure relief groove 38 can effectively reduce the atmospheric pressure that may be generated during the connection process to prevent oil leakage. There are two smoke cartridges 3, and the specifications and sizes of the two smoke cartridges 3 are the same, which increases the oil storage capacity of the electronic cigarette and thus increases the battery life of the electronic cigarette. The position of the insertion port 32 corresponds to the connecting tube 7.

[0029] Through the above technical solution, when the cigarette cartridge 3 is connected to the oil storage tank 2, the dedicated oil inlet 35 at the bottom of the cigarette cartridge 3 is aligned with the connecting pipe 7 of the oil storage tank 2, and the oil sealing silicone 71 of the oil storage tank 2 automatically opens, thereby realizing the continuous oil supply from the oil storage tank 2 to the cigarette cartridge 3. When the oil storage tank 2 is removed and inverted, the oil pressure pushes the oil sealing silicone 71 to rebound and seal the connecting pipe 7, ensuring that there is no oil leakage when removed. At the same time, the pressure relief groove 38 of the insertion port 32 can effectively reduce the atmospheric pressure that may be generated during the connection process to prevent oil leakage.

[0030] Working principle: When in use, the user can connect the cigarette cartridge 3 to the oil storage tank 2 through the oil supply structure. At this time, the smoke oil in the oil storage tank 2 will enter the cigarette cartridge 3 through the oil supply mechanism. Then the user can press the button, and the atomizer core 33 will work. The atomizer core 33 will work to atomize the smoke oil entering the cigarette cartridge 3. Then the user can inhale through the inlet at the top of the smoke outlet 31.

[0031] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
