The air flow channel 15 includes an air inlet channel 151, an air outlet channel 153, and an atomizing channel 152 communicating the air inlet channel 151 and the air outlet channel 153, the air inlet channel 151 communicating with the outside air, and the air outlet channel 153 communicating with the suction nozzle 19. When a user sucks, the air sequentially passes through the air inlet channel 151, the atomizing channel 152 and the air outlet channel 153 to the suction nozzle 19, and the atomized air of the heating component 13 is driven to be sucked by the user.
An air intake hole 183 may be formed in the housing 18, and external air may be introduced into the air intake passage 151 through the air intake hole 183. An air inlet pipe 184 communicated with the air inlet hole 183 and an air outlet pipe 185 communicated with the suction nozzle 19 may be further formed in the housing 18. The intake passage 151 may include a first intake passage 1511 formed by an inner wall of the intake pipe 184, and a second intake passage 1512 that communicates the first intake passage 1511 and the atomizing passage 152, respectively.

The contact part of the first flow restriction 161 and the air inlet pipe 184 is in interference fit to form a sealing connection, so as to effectively prevent liquid leakage. The first flow restriction 161 is usually made of a flexible material, preferably a silicone material, and has a better sealing property at a contact portion with the air inlet pipe 184.
Since the intake cross-sectional area of the first flow restriction 161 is smaller than the intake cross-sectional area of the intake pipe 184, leakage of liquid from the intake pipe 184 can be alleviated. In some embodiments, the cross-sectional air inlet area of the first restriction 161 is within a set range in which the inner surface of the first restriction 161 is capable of forming a surface tension film that prevents condensate or liquid accumulation at the bottom of the atomizer 1 from flowing out of the atomizer 1 through the inlet tube 184. First, theThe cross-sectional area of the air intake of one restriction 161 may be selected according to the material of the first restriction 161. In some embodiments, the first restriction 161 has an intake cross-sectional area of 0.8-1.2mm2E.g. 1.0mm2Or 1.1 mm2. Within the range, the good ventilation effect can be ensured, and liquid leakage can be effectively prevented.

In addition, because the second flow restriction 162 has a smaller outlet cross-sectional area, the atomized gas can be more concentrated when entering the outlet pipe 185, and the mouth feel is more lingering.
The contact part of the second flow restriction member 162 and the air outlet pipe 185 is in interference fit to form a sealing connection, so that liquid leakage is effectively prevented. The second restriction 162 is usually made of a flexible material, preferably a silicone material, and has a better sealing property at a contact portion with the outlet pipe 185.
The second flow restriction 162 may be provided at a lower end portion of the outlet pipe 185. Because the lower end part of the air outlet pipe 185 is usually provided with a chamfer, liquid leakage is easily formed at the chamfer of the lower end part when the air outlet pipe 185 is horizontally placed or the suction posture is changed, the lower end surface of the second flow limiting piece 162 can be flush with the lower end surface of the air outlet pipe 185, so that the positioning during installation can be facilitated, and in addition, the problem that liquid matrix leaks from the air outlet pipe 185 due to shaking in the transportation process can be solved.
