When the tubular element 14 is assembled into the accommodating cavity 69, it is positioned and inserted into the insertion groove to provide positioning. The inner surface of the third section 613 also defines a positioning groove 615. The positioning ridge 614 has an abutment step 616 extending into the positioning groove 615. During assembly, the second through-hole 142 of the tubular element 14 is aligned with the abutment step 616, and the third liquid-conducting element 30 longitudinally abuts the abutment step 616. After assembly, the protruding portion or exposed portion 31 of the third liquid-conducting element 30 passes through the second through-hole 142 of the tubular element 14 and extends into the positioning groove 615.

After assembly, the second support portion 63 abuts and engages the inner surface of the housing 10. In addition, the electrical contact 21 is at least partially assembled from the bracket 60 at the second end 620 into the second support portion 63 of the bracket 60 and is within the second support portion 63. The conductive leads welded to both ends of the heating element 40 extend from the accommodating cavity 69 into the second support portion 63, and then abut the electrical contact 21 to establish an electrically conductive connection between the heating element 40 and the electrical contact 21.
[0104] After assembly, the first rib 821 on the second sealing portion 82 is squeezed or compressed between the first support portion 61 of the bracket 60 and the housing 10, thereby providing a seal. The second rib 822 on the second sealing portion 82 is squeezed or compressed between the second support portion 63 of the bracket 60 and the housing 10, thereby providing a seal.
[0105] The bracket 60 defines an abutment portion 631 at the second end 620 that circumferentially surrounds the bracket 60. The outer diameter of the abutment portion 631 is greater than the outer diameter of the second support portion 63 of the bracket 60, causing the abutment portion 631 to protrude radially outward from the second end 620. After assembly, the abutment portion 631 is located outside the housing 10, and the distal end 120 of the housing 10 abuts against the abutment portion 631.

Accordingly, the bracket 60 is provided with a second positioning structure 630; the second positioning structure 630 extends from the abutment portion 631 toward the second support portion 63; for example, the second positioning structure 630 is a protrusion 630 extending from the abutment portion 631 toward the second support portion 63. When the bracket 60 is assembled into the housing 10 from the distal end 120, the first positioning structure 15 and the second positioning structure 630 cooperate to provide positioning. Furthermore, after assembly, the second positioning structure 630 extends into the first positioning structure 15 to prevent relative rotation between the cylindrical housing 10 and the bracket 60.

In an embodiment, the spacer cavity 64 is defined by the portion of the second section 612 of the accommodating cavity 69 not occupied by the second liquid-conducting element 52. In an embodiment, the spacer cavity 64 is separated or isolated from the liquid storage cavity 112; specifically, the spacer cavity 64 and the liquid storage cavity 112 are separated or isolated by the first liquid-conducting element 51.
[0108] During use, the supersaturated liquid matrix absorbed by the first liquid-conducting element 51 and / or the second liquid-conducting element 52 can partially seep into the spacer cavity 64 for buffering. Specifically, for example, during production, the supersaturated liquid matrix injected into the liquid storage chamber 112 can pass through the first liquid-conducting element 51 and seep into the spacer cavity 64. Alternatively, during use, when the pressure within the liquid storage chamber 112 is greater than the external pressure, the liquid matrix within the liquid storage chamber 112 can pass through the first liquid-conducting element 51 and seep into the spacer cavity 64. Of course, the supersaturated liquid matrix absorbed by the second liquid-conducting element 52 can also seep into or be reabsorbed by the spacer cavity 64 when the internal and external pressures change.

The protrusion height of the first portion 681 is smaller than the protrusion height of the second portion 682. For example, in some embodiments, the first portion 681 has a protrusion height of approximately 0.5 to 1.5 mm, and the second portion 682 has a protrusion height of approximately 2 to 3 mm.
[0112] After assembly, the first portion 681 abuts against the lower surface of the first liquid-conducting element 51 in the longitudinal direction, thereby at least partially supporting the first liquid-conducting element 51. Furthermore, after assembly, the first portion 681 is not in contact with the outer surface of the second liquid-conducting element 52, and a distance exists between the first portion 681 and the second liquid-conducting element 52. Furthermore, the second portion 682 abuts against and clamps the outer surface of the second liquid-conducting element 52. The second portion 682 of the retaining ribs 68 surrounds and clamps the second liquid-conducting element 52, thereby clamping the second liquid-conducting element 52 between the multiple retaining ribs 68 and stably mounting the second liquid-conducting element 52 within the second section 612.

[0114] The ventilation channel 67 is connected between the spacer cavity 64 and the liquid storage cavity 112 to relieve, balance or adjust the pressure of the liquid storage cavity 112. Specifically, when the negative pressure in the liquid storage cavity 112 exceeds a predetermined threshold, the air in the spacer cavity 64 can enter the liquid storage cavity 112 through the ventilation channel 67, thereby relieving the pressure in the liquid storage cavity 112. Figure 7 and Figure 11 Furthermore, when the pressure in the liquid storage chamber 112 is greater than the external pressure and the first liquid guiding element 51 is supersaturated with the adsorbed liquid matrix, the liquid matrix in the liquid storage chamber 112 can flow from the ventilation channel 67 to the spacer cavity 64 to reduce the pressure in the liquid storage chamber 112 .

Figure 8 As shown, adjacent air grooves 622 are connected to each other through the notches 623 or cutouts 624 on the separating flanges 621 therebetween. Figure 8 As shown, the notches 623 on adjacent dividing flanges 621 are staggered in the longitudinal direction of the bracket 60 .
[0128] according to Figure 3 and Figure 12 As shown in , the bracket 60 is also arranged with:
[0129] The air inlet 21 is located at the second end 620 and is used to allow external air to enter the atomizer 100 .
[0130] The atomizer 100 further defines an air flow channel, defining an air flow path from the air inlet 21 through the atomizing assembly to the air outlet 113, so as to deliver the aerosol to the air outlet 113.

[0134] From the air inlet 21, it passes through the second support part 63 longitudinally to the first communication port 625, and then flows from the first communication port 625 to the second communication port 626 and is delivered to the atomizer assembly. The second communication port 626 is closer to the second end 620 of the bracket 60 than the first communication port 625.

The protrusion height of the partition walls 651 is lower than the partition flange 621, so that the communication hole 65 and the air groove 622 are connected without isolation.
[0140] The partition wall 651 is used to block the liquid matrix flowing out of the communicating hole 65 and retain it; when the pressure in the liquid storage chamber 112 or the partition cavity 64 is lower than the external pressure, the liquid matrix retained between the two partition walls 651 flows back from the communicating hole 65 to the partition cavity 64.
