In the present embodiment, the heating element is provided at a position shifted from the position where the first through hole 51 and the second through hole 72 are in direct contact with each other. During installation, the sealing plug 30 is inserted into the atomizing cavity along the suction port 21, and then is inserted into the second through hole 72 formed in the connecting seat 71 in an interference manner after being inserted into the atomizing cavity along the first through hole 51 and the air duct 62, so that the mounting process is not in contact with the heating assembly, and the phenomenon that the heating assembly is deformed due to extrusion of the sealing plug 30 is avoided. Therefore, in the second embodiment of the present invention, the sealing plug 30 does not need to be pre-assembled to the connecting seat 71 to fasten the nozzle cover 20. The installation by the user is effectively facilitated.

Specifically, as shown in fig. 4, in the embodiment of the present invention, in order to facilitate the insertion of the sealing plug 30 along the suction port 21, the aperture of the opening of the suction port 21 may be gradually reduced from outside to inside, i.e. gradually expanded from inside to outside, so as to form a guiding inclined plane. Similarly, the second through hole 72 formed in the connecting seat 71 is designed to be in a gradually expanding manner, so that the sealing plug 30 can be conveniently pulled out and inserted, and the phenomenon that the sealing plug 30 is deflected when being inserted to cause the abutting and clamping is effectively prevented. Meanwhile, when the second through hole 72 is designed to be gradually enlarged, the opening of the end of the connecting seat 71 facing the suction port 21 is larger, and the wall thickness is thinner than that of the connecting seat 71 facing the second sealing seat 70, so that the connecting seat is more easily deformed by the extrusion force of the external sealing plug 30. And the connecting seat 71 has a thicker wall and a stronger stability at the end connected with the second sealing seat 70, so that the connecting seat has a certain positioning performance. The occurrence of a phenomenon that the heat generating member 92 is pressed and deformed due to the misalignment when the sealing plug 30 is inserted is prevented.

Further, as shown in fig. 4, in the second embodiment of the present invention, the sealing plug 30 includes an insertion end and a holding end, the diameter of the insertion end is gradually increased from the inserted end to the holding end, so that the insertion end with a smaller diameter is more easily inserted into the suction port 21, the first through hole 51 provided in the first sealing seat 50 and the second through hole 72 provided in the connecting seat 71, and the diameter of the holding end is greater than the caliber of the suction port 21, and thus is exposed to the outside for the user to hold, without additionally providing the holding handle 31, thereby improving the processing efficiency.
