Theliquid storage assembly 10 includes anelastic member 14, theelastic member 14 is elastically biased between theliquid storage assembly 10 and the atomizingassembly 20. When thebase assembly 30 is detached from theliquid storage assembly 10, the atomizingassembly 20 is ejected out by theelastic member 14. - In this embodiment, the

Thebase assembly 30 is detachably connected to the connectingbody 12. Theliquid sealing member 13 and theelastic member 14 are arranged in sequence along the loading direction of the atomizingassembly 20. Theliquid sealing member 13 can be switched between a liquid discharging position and a liquid sealing position. During the course of connecting thebase assembly 30 to theliquid storage assembly 10, theliquid sealing member 13 moves and compresses theelastic member 14 under the pushing of the atomizingassembly 20, theliquid sealing member 13 is located in the liquid discharging position, and the aerosol-forming substrate in theliquid storage chamber 111 can flow into the atomizingchamber 231.

After the use of theatomizer 100 by the user, during the course of separating thebase assembly 30 from theliquid storage assembly 10, theliquid sealing member 13 is pushed to the liquid sealing position under the elastic restoring force of theelastic member 14, theliquid sealing member 13 blocks the aerosol-forming substrate in theliquid storage chamber 111 from flowing into theatomizing chamber 231. Therefore, when the user needs to clean the dirt in theatomizing chamber 231 or replace theatomizing assembly 20, thebase assembly 30 can be separated from theliquid storage assembly 10, theelastic member 14 can eject theatomizing assembly 20 to the outside, which is convenient for the user to take out the atomizingassembly 20. - Referring to

When the connectingmember 37 and the connectingportion 1232 are connected in place, the fourth abuttingmember 38 can prevent the connectingmember 37 from being in rigid contact with thehousing 11 to cause the both to wear. Specifically, the fourth abuttingmember 38 is made of a material with good sealing properties such as silicone or rubber. - In one embodiment, the connecting
member 37 is provided with a mountinghole 371 for accommodating theatomizer assembly 20, and the mountinghole 371 communicates with the inner cavity of thebase 31. The atomizingassembly 20 can extend into the inner cavity of the base 31 from the mountinghole 371, and theatomizing assembly 20 is electrically connected with thebase 31 and theelectrode contact member 35. - The atomizing
