One end of the push rod 30 is arranged outside the smoking barrel 20, and the other end of the push rod 30 extends into the smoking barrel 20. The end of the push rod 30 disposed at one end outside the smoke tube 20 is provided with a pressing portion (not shown), and the diameter of the pressing portion is greater than that of the rod body of the push rod 30, so that a user can push the push rod 30 into the smoke tube 20 by pressing the pressing portion.

The piston 40 is disposed in the smoke tube 20, one end of the piston 40 abuts against the push rod 30, and one end of the atomizing device 50 is disposed in the piston 40. Wherein the push rod 30 is used for pushing the piston 40 to move relative to the smoke tube 20, the piston 40 moves from a first position shown in fig. 2 to a second position shown in fig. 3 relative to the smoke tube 20, so that the smoke oil in the oil storage cavity 101 flows to the atomization device 50 through the first through hole 201 on the side wall of the smoke tube 20 and the at least one second through hole 401 on the side wall of the piston 40.
