Referring to fig. 1, fig. 2 and fig. 5 in combination, fig. 5 is a cross-sectional view of an embodiment of a mounting base provided in the present application. Mount 120 may include, but is not limited to, a base 121 and a body portion 122 secured to base 121. The mount 120 is provided with a mounting hole 105 penetrating in the vertical direction. The mounting hole 105 penetrates the body 122 and the bottom 121. The bottom 121 is in clamping connection with the inner wall of the main housing 110.

Optionally, the elastic ring 170 may be made of silica gel to achieve good elastic performance. The material of the first absorbent component 180 may be cotton to achieve good absorbent performance.

Referring to fig. 1, 2, 4 and 6 in combination, fig. 6 is a cross-sectional view of one embodiment of an atomizing assembly provided herein. The atomizing assembly 130 may include, but is not limited to, a first porous body 131, a second porous body 132, and a heating element 133. The first porous body 131 is fixed in the mounting base 120. At least part of the first porous body 131 is clamped on the outer side of the second wall 112. A part of the structure of the first porous body 131 is disposed in the liquid storage chamber 102 and contacts with a liquid matrix (not shown) to absorb and conduct the liquid matrix. The second porous body 132 is disposed in a portion of the first porous body 131 beyond the liquid storage chamber 102 and contacts the first porous body 131 to absorb the liquid matrix from the first porous body 131 for heating and atomization. Wherein, the porosity of the first porous body 131 is greater than the porosity of the second porous body 132, so that the speed of the first porous body 131 absorbing the liquid matrix from the liquid storage cavity 102 is greater than the speed of the second porous body 132 absorbing the liquid matrix from the first porous body 131, and the liquid matrix stored in the first porous body 131 is greater than the liquid matrix stored in the second porous body 132, thereby ensuring smooth and sufficient liquid supply to the second porous body 132, and avoiding the bad smell caused by intermittent or insufficient liquid supply.

In the present embodiment, since the liquid matrix sucked by the second porous body 132 is sucked by the first porous body 131 from the liquid storage chamber 102, the liquid matrix is conducted to the contact position between the first porous body 131 and the second porous body 132, and then sucked by the second porous body 132. Therefore, the liquid discharging speed of the atomizing assembly 130 is not affected by the change of the gas pressure and the gravity or the pressure change of the liquid matrix in the liquid storage cavity 102, so that the uniformity of the taste of the atomized total number of the atomizer 100 is ensured. At the same time, the design of the structure can greatly reduce the liquid leakage rate when the atomizer 100 is in the normal discharge.

Further, referring to fig. 2, 4 and 6, the second porous body 132 has an atomization space 107.

The second porous body 132 is pressed against the end face of the second seal 160 facing away from the second wall 112. The positive electrode lead 1332 and the negative electrode lead 1333 are drawn in the relief hole 108 and pass through the relief hole 108 to enter the intake passage 103. The positive electrode lead 1332 is electrically connected to the positive electrode 151. The negative electrode lead 1333 is electrically connected to the negative electrode 152.

Alternatively, the first porous body 131 and the second porous body 132 may be any one of cotton and ceramic.

Further, referring to fig. 2, 5 and 6, the first porous body 131 includes a first contact portion 1311 and a second contact portion 1312 that are connected to each other. The first porous body 131 has a mounting passage 109. The mounting channel 109 extends through the first contact 1311 and the second contact 1312. The first contact portion 1311 passes through the mounting hole 105 into the reservoir 102. At least a portion of the first contact 1311 is disposed in the reservoir 102 and is capable of contacting a liquid matrix (not shown) to absorb and conduct the liquid matrix to the second contact 1312. The portion of the first porous body 131 located in the mounting hole 105 has a structure of a second contact portion 1312. The second contact portion 1312 is accommodated in the mounting hole 105 to be held by the mounting base 120. The second porous body 132 is disposed inside the first porous body 131 and contacts the second contact portion 1312 to absorb the liquid matrix for heating and atomization. Specifically, the second porous body 132 is disposed in the mounting channel 109 corresponding to the second contact portion 1312 and contacts the second contact portion 1312.

In the present embodiment, since the liquid matrix sucked by the second porous body 132 is sucked from the liquid storage chamber 102 by the first contact portion 1311 and then transferred to the second contact portion 1312, and then sucked from the second contact portion 1312 by the second porous body 132. Therefore, the liquid discharging speed of the atomizing assembly 130 is not affected by the change of the gas pressure and the gravity or the pressure change of the liquid matrix in the liquid storage cavity 102, so that the uniformity of the taste of the atomized total number of the atomizer 100 is ensured. At the same time, the design of the structure can greatly reduce the liquid leakage rate when the atomizer 100 is in the normal discharge.

Referring to fig. 1, 2, 5 and 6 in combination, the atomizer 100 further includes a first seal 190. At least a portion of the first seal 190 is disposed in the mounting hole 105 and retained in the mounting seat 120. The first sealing member 190 is pressed against the first porous body 131 toward the end face of the first porous body 131 to seal the first porous body 131 from leakage of the liquid matrix. The first seal 190 is provided with a first gas passing hole 202 for circulating a gas flow and/or aerosol generated in the atomizing space 107.

Alternatively, the material of the first sealing member 190 may be silica gel, so as to achieve good sealing performance.

Further, the second contact portion 1312 is provided with a first chamfer 1312a at the junction of the second contact portion 1312 and the first contact portion 1311. The mounting hole 105 is a stepped hole. The stepped hole includes a through hole 1051 and a half through hole 1052 communicating with each other. The through-hole 1051 is provided with a second chamfer 1051a at the junction of the through-hole 1051 and the half-through-hole 1052. The first chamfer 1312a is attached to the second chamfer 1051a, so that a component parallel to but opposite to the force of the first seal 190 on the atomizing assembly 130 exists at the attachment point of the first chamfer 1312a and the second chamfer 1051a, thereby enhancing the sealing effect of the first seal 190 and simultaneously making the fixation of the atomizing assembly 130 more secure. The joint between the first chamfer 1312a and the second chamfer 1051a is located in the bottom 121, which further enhances the sealing effect of the first seal 190 and the securing effect of the atomizing assembly 130.

It will be appreciated that the elastic ring 170 is mounted to the groove structure 106 to compress the bottom 121 against the first porous body 131. When the junction of the first chamfer 1312a and the second chamfer 1051a is located in the bottom 121, the force of the mount 120 on the atomizing assembly 130 produces a maximum component parallel to but opposite in direction to the force of the first seal 190 on the atomizing assembly 130 at the junction of the first chamfer 1312a and the second chamfer 1051a, thereby further enhancing the sealing effect of the first seal 190 and the securing effect of the atomizing assembly 130.

The second gas passing hole 203 communicates the first gas passing hole 202 with the gas outlet channel 205. The aerosol generated by the atomizing assembly 130 passes through the first air passing hole 202, the second air passing hole 203 and the air outlet channel 205 in sequence, and is released at the air outlet 204.

Alternatively, the material of the second absorbent member 142 may be cotton to achieve good absorbent performance.
