The upper end portion of the atomizer housing 2 faces downward, and a vertical flue outlet 22 is provided in the wall portion of the atomizer housing 2. The upper port portion of the vertical outlet 22 and the concave cavity 21 There is a lateral flue duct 24 communicating between the two. The outer surface of the atomizer housing 2 is provided with an annular groove 27 for storing condensate. The wall of the concave cavity 21 is provided with a gap 211 for the condensate to flow to the annular groove 27. The annular groove 27 and the nozzle housing 1 form an annular cavity 270. [0029] As shown in FIG. 9 and FIG. 10, an upper part of the atomizer housing 1 is provided with an L-shaped notch 23, and the notch 23 and the nozzle housing 1 form a cavity 20, and the cavity 20 will The vertical flue duct 22 is in communication with the lateral flue duct 24.

 [0030] As shown in FIG. 9 and FIG. 10, two annular grooves 27 are provided, and a second gap 271 is provided between the two annular grooves to communicate with each other.

 [0031] As shown in FIGS. 9 and 10, the appearance of the atomizer housing 2 is located below the annular groove 27 and is further provided with a sealing groove 28. A sealing ring 281 is provided in the sealing groove 28 to seal the atomizer. The gap between the housing 2 and the nozzle housing 1 prevents leakage of condensate.

 [0036] As shown in FIG. 4 and FIG. 6, when the user smokes, the outside air enters the atomization device 4 from the air inlet 26, and the smoke liquid passes from the liquid storage chamber 3 through the throttle plate 43, The permeate sheet 44 is transmitted to the heating component 42. The smoke liquid is heated by the heating component and atomized into electronic cigarette smoke. After the smoke is formed, it passes through the vertical flue 22, the cavity 20, the lateral flue 24, and the concave cavity 21, and then passes through. The suction nozzle hole 11 is sucked into the user's mouth, and the flow direction of the airflow is shown by a hollow arrow in FIG. 4.

[0037] When the smoke liquid is atomized after being heated by the heating element, it is inevitable that a small part of the smoke liquid or water vapor is not completely atomized but forms small droplets entrained in the smoke, or part of the water vapor contained in the smoke and the smoke are emitted. The walls of the tunnel are in contact with each other. The cooler flue wall can condense water vapor to form small droplets, and the small droplets form larger droplets during the flow process. In the atomizer of the present invention, after the smoke enters the cavity 20 from the vertical exhaust duct 22, the smoke forms a certain turbulence or rotation in the inside, and part of the droplets will be adsorbed on the inner wall of the cavity 20, which reduces the droplets being directly Opportunity for exhaustion; A vertical baffle 25 is set in the lateral flue duct 24 to block the exhaust speed of the smoke, and some droplets will be blocked on the baffle and flow downward, further reducing the amount of droplets in the smoke; Management, fog The inner wall of the concave cavity 21 provided on the carburetor housing 2 can also absorb liquid droplets in the smoke, and the outer wall of the pipe body 12 formed by the nozzle hole 11 extending vertically inward also blocks the liquid droplets in the smoke and causes it to flow down.
