Inside, the smoke generated after the atomization of the liquid smoke enters the oral cavity from the atomization chamber along the vent pipe 12, so that people feel the feeling of smoking.

In summary, the atomization seat 1 of the cartridge of the second embodiment of the present invention is made of an elastic material, and the atomization seat 1 is provided with a through hole, and the liquid suction member 3 passes through the through hole, sucking. The liquid member 3 and the through hole of the atomizing seat 1 can be tightly fitted, that is, the inner peripheral wall of the through hole can be closely attached to the radially outer periphery of the end of the liquid suction member 3, so that there is no leakage between the liquid suction member 3 and the through hole. The gap can effectively avoid liquid leakage, the gas-liquid isolation effect is good, and the assembly is simple. The electronic cigarette equipped with the above-mentioned cartridge has the advantages of avoiding leakage, good gas-liquid isolation effect, and simple assembly.

In view of the above-described embodiments of the present invention, various changes and modifications can be made by those skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the contents of the specification, and the technical scope thereof must be determined in accordance with the scope of the claims.
