A cartridge and electronic atomizer

Abstract

This utility model discloses a tobacco cartridge and an electronic atomizer. The tobacco cartridge includes a shell, a bottom cover, a bracket, a support base, an oil-proof and breathable membrane, and a heating element. The shell has an outlet channel that forms an oil storage chamber with the inner wall of the shell. The bottom cover is located at the bottom of the shell and is sealed, with an electrode pin and an air supply channel communicating with the oil storage chamber. The bracket has an inlet hole and inner absorbent cotton at both ends, and an air supply hole corresponding to the air supply channel. The support base is located at the bottom of the bracket and has a first through hole and a second through hole, with the oil-proof and breathable membrane covering the first through hole. The heating element passes through the second through hole and has the same diameter, with one end abutting against the absorbent cotton and the other end abutting against the electrode pin. When the e-liquid in the storage chamber is consumed and the air pressure decreases, external air enters through the air supply channel and air supply hole to balance the air pressure, allowing the e-liquid to naturally permeate to the absorbent cotton, ensuring sufficient e-liquid supply to the heating element. The oil-proof and breathable membrane effectively prevents e-liquid leakage, eliminating the possibility of leakage.
