[0036] As Figures 1-6As shown, the utility model discloses a kind of leak-proof oil structure of liquid oil electronic cigarette, including cartridge assembly 100 and tobacco rod assembly 200, the cartridge assembly 100 and tobacco rod assembly 200 are assembled using detachable structure, convenient for user operation.The cartridge assembly 100 is internally provided with atomizing chamber for accommodating tobacco tar, the input end of the atomizing chamber is equipped with oil inlet hole 22, for realizing the transmission of tobacco tar from storage area to atomizing area.To solve the problem of liquid oil electronic cigarette oil leakage, the utility model designs a kind of closed opening structure, which is installed outside the atomizing chamber, and is linked through the assembly relationship of cartridge assembly 100 and tobacco rod assembly 200, to realize the closing and opening of oil inlet hole 22.When cartridge assembly 100 and tobacco rod assembly 200 are separated, the closing opening structure can automatically close oil inlet hole 22;When cartridge assembly 100 and tobacco rod assembly 200 are assembled together, the closing opening structure makes oil inlet hole 22 conductive, so as to guarantee the normal supply of tobacco tar.

[0037] The closing opening structure includes an outer steel pipe support 8 installed outside the atomizing chamber, and the oil inlet hole 22 is arranged on the steel pipe support, so as to fix and support the oil inlet hole 22 through the steel pipe support.Meanwhile, a movable support 10 is movably installed outside the outer steel pipe support 8, and the movable support 10 has at least two movable extension rods 11, which can extend into the bottom cover at the bottom of the cartridge assembly 100 to realize cooperation with other components.

[0038] The bottom end of the movable support 10 is provided with a sealing silica gel ring 9, which wraps the outer steel pipe support 8, to provide reliable sealing effect when the oil inlet hole 22 is closed.The bottom of the sealing silica gel ring 9 is provided with a sealing silica gel gland 12, which fastens the sealing silica gel ring 9 at the bottom of the movable support 10, so as to further enhance the sealing performance in the closed state.

[0039] A positioning assembly shaft sleeve 16 is arranged at a position corresponding to the movable extension rod 11 in the bottom cover of the cartridge assembly 100, and a pin plug 13 is installed in the positioning assembly shaft sleeve 16, and the movable extension rod 11 can extend into the positioning assembly shaft sleeve 16 and cooperate with the pin plug 13.One end of the pin plug 13 is fixedly installed in the movable extension rod 11, and the other end corresponds to the position of the tobacco rod assembly 200.

[0040] When the cartridge assembly 100 and the tobacco rod assembly 200 are assembled, the positioning insertion rod 6 arranged on the tobacco rod assembly 200 is inserted into the positioning assembly shaft sleeve 16, and pushes the pin plug 13, the movable extension rod 11, the movable support 10, and the sealing silica gel ring 9 and the sealing silica gel gland 12, so as to make the originally sealed oil inlet hole 22 conductive, complete the inflow of tobacco tar, and the liquid inlet path 19 is as shown in the figure. Figure 4 The gap formed in the middle and the siphon principle are used to complete the liquid inlet.

[0041] Further, the sealing silica gel ring 9 is designed to have two sealing parts, including a first sealing part 21 and a second sealing part 20, and a gap sealing interval is formed between the two sealing parts. When the cartridge assembly 100 is separated from the rod assembly 200, the oil inlet hole 22 is located in the gap sealing interval, so that the oil inlet hole 22 can maintain a good sealing state even during long-term storage or transportation, thereby preventing leakage of the tobacco tar.

When the pin plug 13 is pressed, the spring 14 is compressed. After the assembly relationship is released, the spring 14 pushes the pin plug 13 to reset by the elastic force, and drives the movable extension rod 11 and the sealing structure to return to the closed state.

[0043] In addition, the movable extension rod 11 passes through a cartridge movable silica gel part 17 on the inner side end of the bottom cover, and the cartridge movable silica gel part 17 is provided with a silica gel sealing protrusion 18 at the passing position of the movable extension rod 11, so as to always maintain the sealing property of the movable extension rod 11 during the movement. The silica gel sealing protrusion 18 is in interference fit with the movable extension rod 11, so as to ensure that the movement of the movable extension rod 11 will not damage the sealing effect, and the sealing property can be ensured even when there is a large traction force.

[0044] The bottom of the shell 7 of the cartridge assembly 100 is designed as a bottom cover, and a plurality of first magnetic attraction blocks 3 are arranged on the bottom cover. The second magnetic attraction blocks 5 are correspondingly arranged on the rod assembly 200. Through the magnetic force of the first magnetic attraction blocks 3 and the second magnetic attraction blocks 5, the reliable assembly of the cartridge assembly 100 and the rod assembly 200 is ensured. In addition, the bottom cover is also provided with a pin hole 2, and the position corresponding to the pin hole 2 of the rod assembly 200 is provided with a conductive pin 4. When the cartridge assembly 100 is assembled with the rod assembly 200, the conductive pin 4 is inserted into the pin hole 2, and the circuit connection is completed, thereby providing power support for the normal work of the atomization chamber.

[0045] The bottom opening position of the positioning assembly shaft sleeve 16 forms a jack 15, and the positioning plug rod 6 is inserted into the positioning assembly shaft sleeve 16 from the jack 15 and cooperates with the pin plug 13.
