In order to enhance the sealing effect, a plurality of seal rings 23 may be provided between the mount 20 and the housing 10. In the present embodiment, the mounting base 20 and the housing 10 are connected by the clamping member 24 and the clamping groove 13.

The upper end of the first connecting portion 41 abuts against the air outlet 12 of the housing 10, so that the vent pipe 40 is communicated with the outside through the air outlet 12. The lower end of the second connecting portion 42 is connected to the mounting base 20, and the second connecting portion 42 communicates with the air inlet 21. The connection between the first connection portion 41 and the second connection portion 42 is provided with a blocking portion 43, and the blocking portion 43 is used for preventing condensate from moving upwards along the inner wall of the breather pipe 40 along with the airflow. In addition, by setting the distance between the blocking portion 43 and the atomizing assembly 30, most of condensate is formed on the inner wall of the second connecting portion 42, thereby affecting the blocking effect of the blocking portion 43 on the condensate. In the present embodiment, the lower end of the second connecting portion 42 abuts against the mounting portion 22, the cross-sectional dimension of the second connecting portion 42 is larger than the cross-sectional dimension of the first connecting portion 41, and the cross-sectional dimension of the blocking portion 43 is gradually reduced in the air flow direction.

In one embodiment of the present utility model, referring to fig. 4, as a user draws in, gas enters the atomizer 100 through the gas inlet 21, the atomizing assembly 30 atomizes the aerosol-generating substrate into an aerosol, and the gas exits the atomizer 100 through the vent tube 40 and the gas outlet 12. During this process, some of the aerosol generated may condense on the inner walls of the vent tube 40 to form condensate. The condensate will move along the inner wall of the vent tube 40 in the direction of the air outlet 12 under the air flow. Due to the provision of the blocking portion 43 between the first connecting portion 41 and the second connecting portion 42, it is difficult for condensate to enter the first connecting portion 41 from the second connecting portion 42, thereby avoiding condensate from exiting from the air outlet 12.

After the condensate is gathered to a certain degree, the condensate can flow to the second liquid absorbing piece 44 along the inner wall of the breather pipe 40 under the action of gravity, and the second liquid absorbing piece 44 absorbs the condensate. The absorbed condensate is led to the end by the drainage column 441 to form droplets, which when formed droplets are sufficiently large, contact the first liquid absorbing member 31 and are absorbed. The atomizing assembly 30 may re-atomize the absorbed condensate to form an aerosol.

The beneficial effects of the atomizer 100 provided by the utility model are that: a blocking portion 43 is provided in the vent tube 40 to prevent condensate formed by aerosol on the inner wall of the vent tube 40 from moving toward the air outlet 12. The lower extreme of breather pipe 40 sets up second liquid absorbing member 44, and the one end that is close to atomizing subassembly 30 on the second liquid absorbing member 44 sets up drainage post 441, and the condensate is absorbed by second liquid absorbing member 44 and forms the liquid droplet at the end of drainage post 441, and the first liquid absorbing member 31 that is located drainage post 441 below absorbs the liquid droplet and atomizes again and form the aerosol to effectively reduce the condensate that gets into in the user's oral cavity, promote user's use experience.
