The liquid guide member 12 is sleeved inside the support member 13, and the micropore 131 is located in the middle section 134 so that the micropore 131 corresponds to the liquid guide member 12 sleeved inside the support member 13, so that the liquid matrix can be absorbed by the liquid guide member after passing through the micropore 131 on the support member 13, thereby preventing the liquid matrix from leaking. In one embodiment of the present application, at least one end of the support member 13 has a positioning notch 135. The first conductive wire 124 and the second conductive wire 125 of the heating element 12 pass through the support member 13 from the positioning notch 135, and the positioning notch 135 makes it convenient for the first conductive wire 124 and the second conductive wire 125 to change their shapes to connect with other conductive components.

[0072] In one embodiment of the present application, Figure 5 As shown, the liquid-conducting member 11 is formed by winding a liquid-conducting sheet 113, and the end of the liquid-conducting sheet 113 is opposite to form an interface 114, and the micropores 131 avoid the interface 114 in the circumferential direction of the support member 13, so that the liquid matrix conducted from the micropores 131 to the liquid-conducting member 11 is away from the interface 114, thereby preventing the liquid matrix from leaking from the interface 114 of the liquid-conducting member 11.

[0074] In one embodiment of the present application, the housing 2 further includes an air pipe 22, one end of the atomizer assembly 1 is connected to the bracket 3, and the other end is connected to the air pipe 22 of the housing 2. The side of the heating element 12 away from the liquid guide 11 is an atomization chamber 126, and the atomization chamber 126 is connected to the air pipe. The liquid matrix atomized by the heating element 12 forms an aerosol in the atomizer 126, and the aerosol can be inhaled by the user through the air pipe 22.

[0075] In one embodiment of the present application, an annular space 127 is provided between the bracket 3 and the support member 13.

The air enters the buffer chamber 35 through the first air inlet channel 36 from the air inlet hole 341, and then enters the atomizing chamber 261 through the second air inlet channel 37, thereby guiding the aerosol generated by the heating element 12 to the trachea 22. In one embodiment of the present application, the first air inlet channel 36 and the second air inlet channel 37 are provided on opposite sides. After the air enters the buffer chamber 35 through the first air inlet channel 36 from the air inlet hole 341, it flows 180° in the buffer chamber 35 and enters the second air inlet channel 37, and then enters the atomizing chamber 261 through the second air inlet channel 37, thereby guiding the aerosol generated by the heating element 12 to the trachea 22 for the user to inhale.

In one embodiment of the present application, the projections of the first guide channel 311 and the second guide channel 321 on the center line of the atomizer assembly 1 do not overlap, so that the liquid matrix leaked from the liquid storage cavity 21 through the first guide channel 261 can be stored in the first buffer cavity 351, and the liquid matrix in the first buffer cavity 351 will enter the second buffer cavity 352 when it accumulates to a certain amount, so as to prevent the liquid matrix from leaking from the air inlet 341 through the first air inlet channel 36.

[0080] In one embodiment of the present application, the bracket 3 also includes a third protrusion 33, which is located between the second protrusion 32 and the base 34, and the third protrusion 33 abuts against the seal 4.
