  • the second seal ring 92 is sandwiched between the lower cover 47 and the inner wall at the opening position of the main housing 46 to ensure the sealing performance inside the housing 4.
  • the lower cover 47 includes a bottom plate 471 and a side plate 472 extending from the bottom plate 471 toward the vaporization cavity 42.
  • a liquid absorbing member 9 covers on an inner surface of the bottom plate 471, and the liquid absorbing member 9 is arranged around the air inlet 44, or the liquid absorbing member 9 is supported on the side plate 472.
  • the condensed to-be-vaporized medium can be prevented from leaking from the air inlet 44, thereby improving the cleanliness for use of the cartridge 100, and preventing a structure (for example, the cigarette rod of the e-cigarette) connected to the cartridge 100 from being corroded and blocked by the condensed to-be-vaporized medium.
  • a conductive pin 10 extends through the lower cover 47.
  • An end of the conductive pin 10 abuts against the heating body 2, and another end of the conductive pin 10 protrudes from an outer surface of the lower cover 47.
  • the other end of the conductive pin 10 is electrically connected to an energy storage member in the cigarette rod of the e-cigarette, so that when the user inhales the e-cigarette, the energy storage member supplies power to the heating body 2 through the conductive pin 10, so that the heating body 2 heats the vaporization liquid, and the vaporization liquid is vaporized into an aerosol and inhaled by the user.
  • the cartridge 100 for the e-cigarette further includes an e-liquid-resistant and air-permeable member 8.
  • the e-liquid-resistant and air-permeable member 8 covers the air inlet 44.
  • the vaporization liquid condensed in the vaporization cavity 42 can be prevented from flowing out from the air inlet 44 in a case of ensuring that the external airflow at the air inlet 44 enters the vaporization cavity 42 smoothly.
  • the cartridge 100 for the e-cigarette further includes an air guide metal plate.
  • the air guide metal plate covers the air inlet 44.
  • the e-liquid-resistant and air-permeable member 8 may have a thin-film structure, and the e-liquid-resistant and air-permeable member 8 is mounted on a side of the air guide metal plate facing away from the air inlet 44.
  • the air guide metal plate is configured to fix the shape of the e-liquid-resistant and air-permeable member 8.
  • the e-cigarette includes the cartridge 100 according to the foregoing embodiment of the present invention and a cigarette rod.
  • An electrical component is arranged inside the cigarette rod.
  • the electrical component is electrically connected to the heating body 2, and the electrical component is configured to supply power to the heating body 2.
  • an electrical component is arranged in the cigarette rod apparatus, and the cigarette rod apparatus has an accommodating groove with an open top.
  • the cartridge 100 includes a vaporization core 200. At least a part of the housing 4 is inserted into the accommodating groove.
  • the vaporization core 200 is electrically connected to the electrical component.
  • the heating body 2 in the vaporization core 200 can be electrically connected to the electrical component through the conductive pin 10.
  • the electrical component can supply power to the heating body 2 of the vaporization core 200 through the conductive pin 10, to realize the conversion of electric energy and heat energy in the heating body 2.
  • the user When the user uses the e-cigarette, the user performs inhalation through the air outlet 45. External air enters the vaporization cavity 42 through the air inlet 44. A sensor in the e-cigarette senses an inhalation action of the user, and the electrical connection between the electrical component and the heating body 2 is turned on and power is supplied to the heating body 2, to heat and vaporize the liquid in the vaporization liquid storage cavity 41 to form smoke. The air enters the vaporization cavity 42 and drives the smoke to be inhaled by the user through the airway 43 and the air outlet 45, thereby ensuring the user's inhalation experience.
  • the e-cigarette according to this embodiment of the present invention uses the cartridge 100 according to the foregoing embodiment of the present invention, which can match the single-inhalation vaporization amount, thereby ensuring the amount of vapor output, and ensuring that the vaporization liquid is fully vaporized.
