Cartridge and electronic cigarette having the same

Abstract

The present disclosure relates to a cartridge and an electronic cigarette. The cartridge includes a housing assembly, an atomizing assembly, an aerosol channel, and a self-deforming partition. The housing assembly has an end provided with a nozzle portion. The atomizing assembly is configured to converting e-liquid stored in the cartridge into atomized aerosol. The aerosol channel is provided inside the housing assembly, and in communication with the nozzle portion. The self-deforming partition is connected to at least one of an inner wall of the housing assembly and an outer wall of the aerosol channel. An e-liquid storage cavity is defined between the self-deforming partition and the outer wall of the aerosol channel. The e-liquid storage cavity is configured to store the e-liquid. The self-deforming partition can collapse and deform toward the aerosol channel as an amount of e-liquid in the e-liquid storage cavity decreases.
