[0025] like Figures 1 to 5 As shown, the utility model discloses an electronic cigarette with a closable oil tank, comprising a shell 1 and an atomization tank 2, an oil storage tank 3 and a switch valve arranged in the shell 1, the oil storage tank 3 is arranged above the atomization tank 2, and an oil filling channel 15 is provided on one side of the atomization tank 2, the oil filling channel 15 is provided with an oil filling hole 4 connected to the lower end of the oil storage tank 3, the switch valve comprises a sealing plug 5 arranged in the oil storage tank 3 and adapted to the oil filling hole 4, and a driving mechanism for driving the sealing plug 5 to move up and down.

[0026] The utility model drives the sealing plug 5 to move up and down through a driving mechanism to seal and open the oil filling hole 4, thereby controlling the connection and disconnection between the oil storage tank 3 and the atomization tank 2, and then preventing oil leakage or overflow by controlling the opening and closing of the oil storage tank 3.

[0027] In the present utility model, the driving mechanism includes a push rod solenoid valve 6, a connecting rod 7 and a return spring 16. The push rod solenoid valve 6 includes a valve body 18 and a push rod 19 arranged in the valve body 18 and capable of extension and contraction. The oil filling channel 15 is also provided with a connecting hole arranged opposite to the oil filling hole 4. One end of the connecting rod 7 passes through the connecting hole and the oil filling hole 4 and is connected to the sealing plug 5. The other end of the connecting rod 7 is in contact with the push rod 19. A limiting retaining spring 17 is provided at one end of the connecting rod 7 close to the push rod 19. The return spring 16 is sleeved on the connecting rod 7 and placed between the limiting retaining spring 17 and the connecting hole. In the initial state, the connecting rod 7 will be stretched downward by the action of the return spring 16, and then the sealing plug 5 will be driven to move downward to fit with its oil filling hole 4, thereby sealing the oil filling hole 4, ensuring the separation of the oil storage tank 3 and the atomization tank 2, and ensuring that the oil in the oil storage tank 3 will not overflow. When the solenoid valve is energized, the push rod 19 pushes the connecting rod 7 to move upward, thereby driving the sealing plug 5 to disengage from the oil filling hole 4. At this time, the oil in the oil storage tank 3 will flow into the atomization tank 2 through the oil filling hole 4 and the oil filling channel 15, so that the oil filling of the atomization tank 2 can be achieved.

[0030] like Figure 5 、 6 As shown, in some embodiments, the middle portion of the sealing plug 5 is further provided with an annular sealing soft edge 21 to further improve the sealing effect.

[0031] In the present invention, the sealing plug 5 is a sealing plug made of soft materials such as silicone or TPE, which can achieve a better sealing effect.

[0032] In the present invention, the housing 1 includes an outer shell 12 and a bracket, the atomization bin 2 is arranged in the bracket, the lower end of the oil storage bin 3 is sealed with the upper end of the bracket, and the outer shell 12 is wrapped around the oil storage bin 3 and the bracket.

[0033] In the present invention, the electronic cigarette with a closable oil tank further includes an atomizer core assembly, which includes an oil storage cotton disposed within the atomizer chamber 2 and a heating core 14 disposed at the center of the oil storage cotton. When filling oil, the oil filling hole 4 is opened, and the tobacco oil in the oil storage chamber 3 flows into the oil filling channel 15. The tobacco oil in the oil filling channel 15 is absorbed by the oil storage cotton, thereby completing the filling of the atomizer chamber.

[0034] like Figures 1 to 4 In the utility model shown, the electronic cigarette with a closable oil tank also includes a nozzle 13. A receiving groove is provided at the upper end of the oil storage tank 3, and an air outlet pipe 9 connected to the receiving groove is provided at the upper end of the atomization tank 2.

[0037] In the present invention, the circuit board 10 is further provided with a charging interface, and the bottom of the shell 1 is provided with a mounting hole adapted to the charging interface and an air inlet hole connected to the atomization bin 2.

[0038] In the present invention, the upward movement stroke of the push rod of the push rod solenoid valve is greater than 1.5 mm, and the diameter of the oil filling hole is greater than 4 mm, thereby ensuring the oil filling effect.

[0039] Under normal conditions, the connecting rod 7 is in the lower end position under the action of the return spring 16. At this time, the sealing plug 5 at the upper end of the connecting rod 7 will be inserted downward into the oil filling hole 4 to close the oil filling hole 4, ensuring that the oil storage tank 3 will not leak oil during the production, packaging, transportation and normal use of the product. During use, the circuit board 10 controls the operation of the push rod solenoid valve 6. At this time, the push rod 19 of the push rod solenoid valve 6 will push the connecting rod 7 to overcome the elastic force of the return spring 16 and move upward. At this time, the sealing plug 5 will be lifted up and separated from the oil filling hole 4, so that the oil filling hole 4 is opened. At this time, the oil in the oil storage tank 3 will enter the oil filling channel 15 from the oil filling hole 4 and then flow into the atomization tank 2 to replenish the oil storage cotton. After a period of oil replenishment, the push rod solenoid valve 6 is de-energized, the push rod 19 is reset, and the sealing plug 5 is reset under the action of the return spring 16 to seal the oil filling hole 4. During the entire product use cycle, the above actions will be repeated many times until the oil in the oil storage tank 3 is completely exhausted. The amount of oil added can be counted and calculated based on the opening time of the oil filling hole 4, so as to control the opening and closing time of the push rod solenoid valve 6 to prevent excessive oil replenishment. The oil replenishment during use can be counted and calculated based on the user's suction time, so as to control the opening and closing of the push rod solenoid valve 6 to prevent excessive oil replenishment.

[0040] The utility model has a simple structure and realizes the separation of the smoke oil by arranging the oil storage bin 3 and the atomization bin 2, thereby ensuring that the oil is not likely to leak during transportation or under high temperature conditions.
