A refill assembly, an atomizing assembly, an atomizer, and an aerosol-generating device

Abstract

Embodiments of the present application provide a refill assembly, an atomization assembly, an atomizer and an aerosol-generating device. The refill assembly is provided with a refill cavity. The refill assembly comprises a first sealing portion and a first conductive portion. The first sealing portion seals the outside of the refill assembly and the refill cavity, and can be in contact with the atomization assembly and remove the sealing of the refill cavity by the first sealing portion. The first conductive portion is used to be in contact with the atomization assembly and remove the sealing of the liquid storage cavity, so that the refill cavity and the liquid storage cavity are in communication. The refill assembly of the embodiments of the present application can realize the opening of the refill cavity and the opening of the liquid storage cavity of the atomization assembly synchronously through the contact with the atomization assembly, thereby improving the convenience of user operation, reducing the probability of leakage of the aerosol-generating substrate in the refill cavity without entering the liquid storage cavity, and improving the user experience.
