Abstract (en)
[origin: US2022000181A1] A cartridge and an electronic cigarette are provided. The cartridge includes an atomizer including a supporting base and an atomizing head installed in the supporting base; a liquid storage container installed on the supporting base, a liquid storage chamber being defined between the liquid storage container and the supporting base; a liquid pump configured for pumping e-liquid in the liquid storage chamber to the atomizing head; a constant pressure member installed in the supporting base and only allowing external air to flow into the liquid storage chamber in one direction. Through the arrangement of the constant pressure member, the air in the liquid storage chamber can be quickly replenished, so that the air pressure in the liquid storage chamber is balanced, and the piezoelectric pump can pump the e-liquid more smoothly.
