The atomizer bracket 20 is accommodated in the shell 10, and is provided with an air outlet 23, a mounting groove 24 and a liquid channel 25 arranged in sequence and connected along a first direction A. The liquid channel 25 extends along a second direction B basically perpendicular to the first direction A and penetrates at least one side of the atomizer bracket 20. The notch of the mounting groove 24 is oriented basically perpendicular to the first direction A.

In this embodiment, the atomizer bracket 20 is a flexible bracket, and its outer peripheral surface is engaged with the inner wall surface of the shell 11 and sealed. The inner wall surface of the mounting groove 24 is engaged with the atomizer assembly 30 and can form a seal. The atomizer bracket 20 can also be sealed with the bottom cover 40 to avoid leakage. Relatively speaking, by limiting the atomizer bracket 20 to be a flexible bracket, at least three seals can be saved, so that the atomizer 100 has very few or even no locations that need to be sealed, which can effectively reduce costs and simplify the structure of the atomizer 100.

For example, the atomizing bracket 20 is made of elastic materials such as silicone, rubber or thermoplastic elastomer (TPE).

Optionally, the atomizing bracket 20 is a rigid bracket, and is joined to the inner wall surface of the housing 11 via a sealing member to form a sealing structure to prevent liquid leakage.

As shown in FIG. 8 , the inner wall of the mounting groove 24 includes a sealing surface 241 , which is used to seal with the outer wall of the atomizer assembly 30 , so that the inner wall of the mounting groove 24 cooperates with the atomizer assembly 30 to form an atomizer chamber 201 isolated from the liquid channel 25 .

The airway is smoother, which can effectively reduce the loss of aerosol and increase its mist output. The airway distance is shorter than that of setting the atomizing chamber 201 on the side away from the air outlet 23. The temperature of the aerosol reaching the oral cavity is higher, and the amount of aerosol is also greater, which is beneficial to improving the taste.

The first direction A and the second direction B are substantially perpendicular, that is, the first direction A and the second direction B may be perpendicular or nearly perpendicular, and some deviations from a right angle may be allowed between the first direction A and the second direction B, for example, the deviation may be within a range of plus or minus 5 degrees.
