The sealing member 60 includes a first sealing portion 61 formed on the outer periphery of the accommodating end 42, a second sealing portion 62 extending from the first sealing portion 61 toward the closed end 41, and a third sealing portion 63 formed on the outer periphery of the top of the closed end 41 and connected to the second sealing portion 62 as a whole. The first sealing portion 61 includes a first sealing ring 612 integrally formed around the accommodating end 42 and the outer periphery of the notch 44, and an atomizer core installation cavity 611 formed on the bottom surface of the blocking portion 441 of the notch 44 and the inner side surface of the accommodating end 42. The outer surface of the atomizer core installation cavity 611 corresponding to the side wall where the outer airway 452 is located is recessed inward to form a recessed channel 614 connected to the outer airway 452, and the lower end of the recessed channel 614 passes through the side wall of the atomizer core installation cavity 611 to form a through hole 613. The through hole 613 , the recessed channel 614 , the outer air channel 452 , the longitudinal air channel 451 and the docking air channel 453 together constitute the air channel 45 .

[0043] The second sealing portion 62 is disposed on both sides of each of the outer air passage 452 , the recessed channel 614 and the through hole 613 , that is, the outer air passage 452 , the recessed channel 614 and the through hole 613 are located between two second sealing portions 62 .

[0044] The third sealing portion 63 includes a second sealing ring 631 integrally formed on the outer periphery of the closed end 41 , a third sealing ring 633 integrally formed on the inner wall surface of the docking air passage 453 , and an oil inlet hole 632 opened corresponding to the oil passage 43 .

[0045] The atomizer core 30 is assembled at the upper end of the atomizer core installation cavity 611 of the sealing member 60, and the atomizer core 30 is surrounded by the side walls of the atomizer core installation cavity 611. The atomizer core 30 is located above the through hole 613, and an atomizer cavity 80 is formed below the atomizer core 30, and the through hole 613 is connected to the atomizer cavity 80. The upper edges of the two longitudinal sides of the atomizer core 30 are supported by the resisting portion 441 to prevent the atomizer core 30 from moving upward, and the two lateral sides of the atomizer core 30 are abutted against the inner wall surface of the accommodating end 42.

[0046] Key References Figure 2 , Fig.10 As shown, the atomizer core 30 includes a liquid permeation surface 31 exposed in the oil passage 43 and in contact with the smoke oil in the oil passage 43 and an atomization surface 32 located above the atomization chamber 80. A heating wire 33 for heating the atomizer core 30 is provided on the atomization surface 32. The atomizer core 30 is made of porous ceramic material.

[0047] The closure body is inserted from the bottom of the cigarette bomb tube 10. After insertion, the insertion portion 133 of the free end of the flue 13 is inserted into the docking airway 453 of the closure member 40 and clamps the third sealing ring 633 of the sealing member 60 with the inner wall surface of the docking airway 453 to achieve sealing. The first and second sealing rings 612 and 631 respectively press the inner wall surface of the tube body 11 of the cigarette bomb tube 10 to achieve a double sealing structure, and the second sealing portion 62 presses the inner wall surface of the tube body 11 to make the airway 45 independently sealed.

[0048] The smoke oil stored in the liquid storage chamber 12 enters the oil passage 43 of the closure member 40 through the oil inlet hole 632 of the sealing member 60, so that the smoke oil fully contacts the liquid permeation surface 31 of the atomization core 30 located below the oil passage 43. When the air passage 45 inhales in the flue 13, the smoke atomized in the atomization chamber 80 passes through the through hole 613, the recessed channel 614, the outer air passage 452, the longitudinal air passage 451 in sequence, and finally enters the flue 13 through the docking air passage 453 and is sucked out.

[0049] When the sealing member 60 is injection molded, the first and third sealing portions 61 , 63 are connected as one body through the second sealing portion 62 .

[0050] The sealing body of the present application forms the sealing member 60 integrally on the sealing member 40, and there is no need to assemble the sealing ring separately, and the automatic assembly can be easily realized. The sealing member 60 forms the first and second sealing rings 612 and 631 respectively at the closed end 41 and the receiving end 42 of the sealing member 40. The second sealing ring 631 directly contacts the liquid storage chamber 12 as the first sealing line of defense, and the airway 45 side between the first and second sealing rings 612 and 631 is independently sealed by the second sealing part 62. Even if the smoke oil leaks out of the second sealing ring 631, it will not pollute the airway 45.

The base 50 is also integrally formed with at least one pair of conductive columns 55 and an air inlet 54 that passes through the base 50 and is connected to the atomization chamber 80. A pair of conductive columns 55 are electrically crimped to the two ends of the heating wire 33 to transmit electrical energy to heat the heating wire. The conductive column 55 can be in the form of an elastic contact piece, which abuts against the heating wire 33 with elastic force, and provides a certain support to the atomization core 30 to prevent the atomization core 30 from moving downward and falling off under the action of a strong external force.

[0059] The sealing body of the cigarette cartridge of the present application integrates the closure 40 and the sealing member, avoiding the defect that the separate sealing ring needs to be manually assembled and cannot be assembled automatically; at the same time, the cigarette cartridge of the present application directly fixes the atomizer core 30 in the atomizer core installation cavity 611 of the closure body, without the need for the base 50 and the closure body to clamp the atomizer core 30.
