Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes, and in particular to an atomization core and a cigarette cartridge. Background Art

[0002] Patent application No. 201811033876.0 of the People's Republic of China discloses an atomizer and an electronic cigarette, which includes an atomizer core, a first plastic part for assembling the atomizer core, a second plastic part, a shell sleeved on the outside of the first plastic part, and a cover body that is buckled with the shell and covered on the outside of the second plastic part. A first sealing portion is sandwiched between the atomizer core and the first plastic part, and a second sealing member is sandwiched between the outer periphery of the first plastic part and the shell. An air hole is also provided on the first plastic part, and the shell is provided with an air passage connected to the air hole. The air hole and the air passage are connected to each other and a third sealing member is sandwiched between each other. The first, second and third sealing members are provided to prevent the leakage of smoke oil from the shell.

[0003] The atomizer core includes an oil absorption surface connected to the liquid storage chamber and an atomization surface connected to the airway. The liquid permeation surface is provided with an oil groove, which is formed by the depression of the oil absorption surface. The contact surface between the oil groove and the smoke oil is insufficient. When the electronic cigarette is inverted, the smoke oil leaves the oil groove, and when it returns to the original position for inhalation, the smoke oil will not penetrate into the atomization surface sufficiently, resulting in insufficient mist or burning problems. At the same time, the liquid storage chamber is in a sealed state. When the smoke oil gradually decreases, the liquid storage chamber may be in a negative pressure state, and the inverted smoke oil cannot penetrate the atomizer core; or affected by temperature, humidity, air pressure, etc., part of the smoke oil in the liquid storage chamber vaporizes, causing the liquid storage chamber pressure to be too high, which will eventually cause the smoke oil to completely penetrate the atomizer core and cause oil leakage.

The upper surface of the protrusion 35 is higher than the top surface of the oil groove wall 342, increasing the surface area of ​​the second inclined surface 351. The design of the first inclined surface 343 and the second inclined surface 351 can increase the contact area between the liquid seepage surface 31 and the tobacco oil in the liquid storage chamber 12, increase the amount of oil sticking to the liquid seepage surface 31, and avoid the problem of insufficient tobacco oil in the atomizer core 30 when the tobacco oil is separated from the liquid seepage surface 31 when the oil in the liquid storage chamber 12 is insufficient.

The bottom of the first sealing part 61 of the sealing member 60 is provided with a second air gap 619 communicating with the third air groove 493 to the air channel 45 or the through hole 613. In this way, the liquid storage chamber 12 is connected to the air channel 45 through the first air gap 639, the air groove 49 and the second air gap 619, so that the air pressure in the liquid storage chamber 12 is kept balanced with the outside.

The depth and width are adaptively adjusted to achieve smooth airflow, and the smoke oil cannot leak from the first and second air gaps 639, 619. Specifically, the depth of the first and second air gaps 639, 619 is between 0.05-0.1mm, and the width of the first and second air gaps 639, 619 is between 1-2mm. The above depth and width refer to the values ​​of the seal 60 in the initial state before it is pressed into the smoke bomb tube 10. After the seal 60 and the closure 40 are pressed into the smoke bomb tube 10, the seal 60 is made of elastic sealing material and will be squeezed and deformed. When in the extrusion working state, the final depth and width will be less than the initial value. In this way, it is ensured that the smoke oil does not leak, while maintaining the air pressure balance in the liquid storage chamber 12.

[0063] The cigarette cartridge of the present application is provided with at least one balancing air groove 49 on the outer side of the closure 40, and air gaps 639, 619 connected to the balancing air groove 49 are provided on the sealing member 60 wrapped outside the closure 40, so that the liquid storage chamber 12 is connected to the airway 45 or the outside through the balancing air groove 49 and the air gaps 639, 619 to balance the pressure inside the liquid storage chamber 12, so that the air pressure in the liquid storage chamber 12 is kept balanced, and the situation that the negative air pressure causes the smoke oil to be unable to penetrate into the atomization core 30 or the high air pressure causes oil leakage occurs.

[0064] Key References Figure 2 , Figures 11 to 13 As shown, the liquid permeation surface 31 of the atomization core 30 is exposed in the oil passage 43 and contacts the tobacco oil in the oil passage 43 , and the atomization surface 32 is located above the atomization chamber 80 .

[0065] The closure body is inserted from the bottom of the cigarette cartridge 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 cartridge 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.

[0066] 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.

[0067] 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 .

[0068] 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.

[0069] Please continue reading Figure 2 , Fig.14 , Fig. 20As shown, the base 50 includes a base body 51 and an extension portion 52 extending upward from the base body 51 and inserted into the cigarette cartridge tube 10. The lateral ends of the extension portion 52 are provided with second buckle portions 53 that are buckled with the first buckle portions 14 on the lateral sides of the tube body 11 of the cigarette cartridge tube 10, and the first and second buckle portions 14, 53 can be a clamping hole and a clamping block structure respectively. 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 33. 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.

[0077] 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. The bottom of the atomizer core 30 is only supported by the conductive column 55, and the clamping force of the atomizer core 30 comes from the elastic cavity wall of the atomizer core installation cavity 611. In this way, it is only necessary to directly press the closure body, the atomizer core 30, and the base 50 into the cigarette cartridge tube 10 automatically in sequence, which simplifies the automated assembly process. At the same time, the components of this case are minimized, and the assembly is easier.
