1. A cartridge comprising:
a cartridge housing that defines a vent tube and encloses a liquid storage cavity;
a sealing member made of an elastic material and is disposed at one end of the cartridge housing, forming a seal for the liquid storage cavity;
a first blind hole and a second blind hole formed on one end face of the sealing member away from the liquid storage cavity;
a first electrode and a second electrode mounted on the sealing member by insertion into the first blind hole and the second blind hole, respectively;
an atomizing head disposed in the cartridge housing in alignment with the vent tube, wherein the atomizing head comprises an atomizing tube housing an atomizing cavity and a heating structure, and the atomizing tube comprises a liquid inlet on a wall thereof; and
a separating assembly comprising a casing connected to a lifting rod, wherein the lifting rod extends through the vent tube and the casing sleeves over a portion of the vent tube and a portion of the atomizing head, when the lifting rod is in a first state, the casing blocks the liquid inlet in the atomizing tube, when the lifting rod is lifted to a second state, the casing is lifted with the lifting rod to expose the liquid inlet to the liquid storage cavity such that a liquid in the liquid storage cavity enters the atomizing tube through the liquid inlet,
wherein the lifting rod is separable from the casing and withdrawn from the vent tube.
