The atomizer according to claim 3, wherein a second guide tube for guiding the movable sleeve to move axially is disposed on the liquid storage member, a port of a first end of the second guide tube is communicated with the through hole, the sliding tube is slidably disposed in the second guide tube, and the suction nozzle is rotatably sleeved on the second guide tube along the liquid storage member.
6. The atomizer according to claim 5, wherein a resilient member is further provided in said second guide tube for resiliently urging said sliding tube in a direction away from said suction nozzle.
7. The atomizer according to claim 6, wherein an outer diameter of the threaded tube is smaller than an outer diameter of the sliding tube to form a first step surface at a joint of the threaded tube and the sliding tube, a port of the second end of the second guide tube is provided with a holding portion, the elastic member is sleeved outside the threaded tube, a first end of the elastic member is held against the holding portion, and a second end of the elastic member is held against the first step surface.
8. The atomizer according to any one of claims 2 to 7, wherein the liquid-core separating assembly further comprises a fixed sleeve housed in the movable sleeve, a portion of the interior of the liquid storage member outside the movable sleeve defines the liquid storage chamber, the interior of the fixed sleeve forms the atomizing chamber, and a liquid inlet communicated with the atomizing chamber is formed in a side wall of the fixed sleeve; when the movable sleeve moves to the first position, the liquid inlet is blocked by the movable sleeve to close the liquid storage cavity; when the movable sleeve moves to the second position, the liquid inlet is exposed to open the liquid storage cavity.
9. The atomizer according to claim 8, wherein said fixed sleeve comprises an atomizing tube having a first end fixed in said liquid storage member and a connecting tube connected to a second end of said atomizing tube, said atomizing tube being received in said partition, said atomizing chamber being defined by an inner space of said atomizing tube, said liquid inlet opening being formed in a side wall of said atomizing tube, said connecting tube being slidably inserted in said sliding tube.
