The oil locking cavity 305 is symmetrically arranged relative to the central axis of the atomization cavity 304, so that gaseous tobacco tar in each part of the atomization cavity 304 can flow into the oil locking cavity 305, and the possibility that the gaseous tobacco tar in the atomization cavity 304 flows into the air inlet 404 is further reduced. In other embodiments, the number of oil locking cavities 305 may be other, such as one or three.

Through the above structure, the condensed oil or gaseous tobacco tar in the oil locking cavity 305 is easier to flow into each annular oil locking groove 602 through the diversion trench 604, and then the condensed oil formed by the tobacco tar can be more uniformly distributed in each annular oil locking groove 602, so that more condensed oil can be locked on the surface of the flexible oil locking assembly 60.

In addition, when the user stops sucking and a large amount of atomized tobacco tar remains in the atomization chamber 304, the gas in the atomization chamber 304 can quickly flow into the oil locking chamber 305 along the portion of the oil inlet 302 not covered by the oil absorbent cotton 80, so that the gaseous tobacco tar can be contacted with and absorbed by the oil absorbent cotton 80 to a greater extent.

Specifically, in the present embodiment, the side chamber walls of the lock chamber 305 near the atomizing chamber 304 are formed by the seal bracket 30 alone, and the other three side chamber walls of the lock chamber 305 are formed by the seal bracket 30 and the mounting bracket 40 together; the oil inlet 302 is formed on the sealing support 30 and has a rectangular shape. In other embodiments, the side chamber walls of the lock chamber 305 adjacent to the atomizing chamber 304 may also be formed by the mounting bracket 40 alone or by the seal bracket 30 and the mounting bracket 40 together; the oil inlet 302 can also be arranged on the mounting bracket 40; the oil inlet hole 302 may have other shapes, such as a circular shape.

In some embodiments, the flexible oil locking assembly 60 includes an oil absorbing section 62 and an oil locking section 64 connected to each other, the oil absorbing section 62 and the oil locking section 64 are sequentially arranged in a direction from the air inlet chamber 102 to the air outlet chamber 202, an annular oil locking groove 602 is formed in the oil locking section 64, the oil absorbing cotton 80 surrounds a side wall of the oil absorbing section 62, and the oil absorbing cotton 80 is closely attached to a chamber wall of the oil locking chamber 305.

Through the structure, the wall of the oil inlet hole 302 close to the air inlet cavity 102 is coplanar with the wall of the oil locking cavity 305 close to the air inlet cavity 102, after the gas in the atomization cavity 304 flows into the oil locking cavity 305, the gas can flow to the annular oil locking groove 602 only through the oil absorbing cotton 80, and then the oil absorbing cotton 80 can guide gaseous tobacco tar into the annular oil locking groove 602 more uniformly, so that condensed oil in the annular oil locking groove 602 can be distributed more uniformly, and finally the annular oil locking groove 602 can lock more condensed oil.

In addition, in the process of atomizing the tobacco tar by the waste heat in the heating component 50, gaseous tobacco tar is continuously generated at the heating component 50 and is diffused in a direction away from the heating component 50; the side surface of the protruding portion 42 and the side cavity wall of the atomizing cavity 304 form a drainage space 1022, and under the pressure of the gas, the gaseous tobacco tar in the drainage space 1022 can flow into the oil inlet 302, so that the possibility that the gaseous tobacco tar flows into the air inlet cavity 102 through the air inlet 404 is further reduced.

Specifically, the oil inlet 302 is rectangular, and the oil inlet 302 includes four hole walls, where the hole wall closest to the air inlet 102 is the hole wall of the oil inlet 302 close to the air inlet 102.

The side walls of the first bulge 422 and the second bulge 424 are inclined, the cross-sectional area of the first bulge 422 is gradually reduced along the direction from the air inlet cavity 102 to the air outlet cavity 202, and the cross-sectional area of the second bulge 424 is also gradually reduced; and thus, both the side walls of the first protrusion 422 and the side walls of the second protrusion 424 have a guiding effect on the air flow in the drainage space 1022. In addition, even if the gaseous tobacco tar liquefies within the atomization chamber 304 to form a condensate, the drainage space 1022 can provide a flow diversion for the condensate such that the condensate flows into the oil lock sump 602.

In other embodiments, the number of air intake holes 404 may be other, such as one or three; the air intake apertures 404 may also be other shapes, such as rectangular; the boss 42 may also be other shapes, such as a cuboid.

Through the structure, the wall of the oil inlet hole 302 close to the air inlet cavity 102 is coplanar with the wall of the oil locking cavity 305 close to the air inlet cavity 102, the strip-shaped supporting piece 44 is arranged on the wall of the oil locking cavity 305 close to the air inlet cavity 102, the oil inlet hole 302 is opposite to the strip-shaped supporting piece 44, and the gas in the atomization cavity 304 can be contacted with the wall of the oil locking cavity 305 close to the air inlet cavity 102 after flowing into the oil locking cavity 305; under the action of the strip-shaped supporting pieces 44, the surface of the cavity wall, close to the air inlet cavity 102, of the oil locking cavity 305 is rougher, so that gaseous tobacco tar is easier to condense on the cavity wall, close to the air inlet cavity 102, of the oil locking cavity 305, and gaps between two adjacent strip-shaped supporting pieces 44 can also have a locking effect on condensed oil.

Specifically, the gap between the strip-shaped support 44 and the wall of the oil locking cavity 305 away from the air inlet cavity 102 is adapted to the height of the flexible oil locking assembly 60, and then the strip-shaped support 44 and the wall of the oil locking cavity 305 away from the air inlet cavity 102 can clamp the flexible oil locking assembly 60, so that the flexible oil locking assembly 60 is fixed in the oil locking cavity 305.
