Aerosol generated in the atomizing assembly 20 can enter the air outlet 15 and be guided through the air outlet 15 into the mouthpiece 11 to be inhaled by a user through the mouthpiece opening 110. The other end of the atomization assembly 20 is secured to a lower end cap 142. At least a portion of the lower end cap 142 defines an air inlet passage through which external air enters the interior cavity of the atomizing assembly 20.
In the disposable aerosol-generating device, the atomizing unit 20 and the reservoir 13 are accommodated in an inner cavity of an upper end portion of the housing 10, and the battery 51 and the airflow sensing switch 52 are mainly provided in an inner cavity of a lower end portion of the housing 10. The atomization assembly 20 is electrically connected to a battery 51 and an air flow trigger switch 52.

The air flow sensing switch 52 is installed on the bottom cover 12, and an air inlet through which external air enters the inner cavity of the case 10 is provided on the bottom cover 12.
Referring to fig. 2 to 7, the atomizing assembly 20 includes a sleeve 21, an insulating base 22, a heating element 23, and a liquid guiding element 24. The heating element 23 includes a heating portion 231 and a conductive portion 232, and the conductive portion 232 is electrically connected to the power supply assembly to supply power to the heating portion 231. In one example, referring to fig. 7, the heating unit 231 is preferably a heating sheet having a mesh structure, and two conductive portions 232, i.e., a first conductive portion 233 and a second conductive portion 234, are provided at both ends of the heating sheet. The conductive part 232 includes a conductive pin 2321 and a conductive lead 2322, wherein an insulating sheath is sleeved outside a portion of the conductive pin 2321 to form the conductive lead 2322. The heating plate comprises two free sides which are respectively a first free side and a second free side, in the installation process, the heating plate is enclosed to form an unclosed similar tubular structure, the two free sides of the heating plate are connected with two conductive pins 2321, the first conductive pin is connected with the first free side of the heating plate, and the second conductive pin is connected with the second free side of the heating plate. The two free sides of the heater chip are spaced apart to prevent the first and second conductive leads from contacting and shorting.
The sleeve 21 has a hollow accommodating cavity 211, the heating portion 231 of the heating element 23 is accommodated in the accommodating cavity 211, a part of the conductive portion 232 on both sides of the heating portion 231 is accommodated in the accommodating cavity 211, and the other part of the conductive portion 232 extends to the outside of the accommodating cavity 211. The portion of the conductive portion 232 extending to the outside of the receiving cavity 211 is mainly provided in the form of a conductive lead 2322, so as to prevent the conductive portion 232 from contacting other metal components or two conductive portions 232 from contacting to form a short circuit. The first conductive portion 233 includes a first conductive lead 2331 and the second conductive portion 234 includes a second conductive lead 2341.
An insulating seat 22 is connected to the other end of the sleeve 21, and the insulating seat 22 is preferably made of a plastic material. A through hole 221 is formed in the insulating base 22 to fix a first conductive lead 2331 and a second conductive lead 2341 of the heating element 23. In one example provided in the present application, only one through hole 221 is provided on the insulator base 22. The first conductive lead 2331 and the second conductive lead 2341 are inserted into the through hole 221 in a relatively upright and loose state without being bent or pulled to be fixed to the outside of the two free sides of the heating part 231. The distance between the first conductive lead 2331 and the second conductive lead 2341 is not greater than the distance between the two free sides of the heat patch, so that the body portion of the heat patch is always in a relaxed state during the positioning of the first conductive lead 2331 and the second conductive lead 2341. In a preferred embodiment, the distance between the first 2331 and second 2341 conductive leads is equal to the distance between the two free sides of the heat patch, so that the first 2331 and second 2341 conductive leads do not require secondary positioning with respect to the body portion of the heat patch during securement, and the relative position between the body portion of the heat patch and the wicking element 24 can be positioned in accordance with a predetermined procedure. It will be appreciated that if the first and second conductive leads 2331 and 2341 are positioned at a distance greater than the distance between the two free sides of the heat patch, the first conductive lead 2331 needs to be positioned a second time relative to the heating portion 231 of the heat patch during assembly of the second conductive lead 2341, for example, by bending the first and second conductive leads 2331 and 2341 and then securing them inside the through hole 221 of the insulating base 22. The secondary positioning of the first and second leads 2331 and 2341 of the heating plate may cause the heating portion 231 of the heating plate to be under extended tension, such that the fixed shape of the heating plate is distorted, thereby affecting the liquid matrix transfer effect between the liquid guiding member 24 and the heating element 23, and affecting the local resistance of the heating portion 231 of the heating element 23, thereby affecting the uniformity of the heating efficiency of the heating plate as a whole.
The insulating base 22 is provided with a flange 222 extending circumferentially, the flange 222 divides the insulating base 22 into two sections, a first section above the flange 222 can be accommodated in the accommodating cavity 211 of the sleeve 21, and a fixing ring 25 is sleeved outside a second section below the flange 222. In some embodiments, the fixing ring 25 is riveted on the outer wall of the second section of the insulating base 22, so that the conductive leads 2322 can be firmly inserted into the through holes 221 of the insulating base 22 without shaking after being pressed. In other examples, after the first conductive lead 2331 and the second conductive lead 2341 are inserted into the through hole 221 of the insulating base 22, the first conductive lead 2331 and the second conductive lead 2341 may be securely positioned inside the through hole 221 by using glue.
A through hole 223 is further formed on the insulating base 22, the through hole 223 is communicated with the accommodating cavity 211 of the sleeve 21, and external air flow can enter the inside of the atomizing assembly 20 through the through hole 223 of the insulating base 22. In a preferred embodiment, a perforation 221 is provided on one side of the through-hole 223, the perforation 221 being sized to receive two conductive leads 2322. Specifically, a raised rib 224 is provided on one side of the insulating base 22, and the inner space of the rib 224 defines a through hole 221. The height of the ridge 224 is substantially determined by the inner diameter of the through hole 221. The rib 224 generally comprises two sections, a first section of the rib 224 disposed above the flange 222 and a second section of the rib 224 disposed below the flange 222.
Both the through hole 221 and the through hole 223 are arranged inside the insulating holder 22 and extend substantially the same distance in the longitudinal direction of the insulating holder 22, so that the through hole 221 is arranged close to the through hole 223. In a preferred embodiment, a projected area of the through hole 223 in the axial direction substantially coincides with a projected area of the unclosed tubular space formed by the configuration of the heating part 231 of the heating element 23 in the axial direction, and the through hole 221 is substantially aligned with a spaced area between two free sides of the heating part 231 of the heating element 23 in the longitudinal direction, so that the conductive part 232 of the heating element 23 can be directly inserted into the through hole 221 in a relatively upright state. In order to facilitate the conductive lead 2322 to penetrate into the through hole 221 and be fixed in the through hole 221, only a section of the partition wall 225 is disposed between the through hole 221 and the through hole 223, the portion of the conductive lead 2322 above the partition wall 225 can enter the through hole 221 in a relatively free state, and the partition wall 225 provides a supporting function for the conductive lead 2322, so that the conductive lead 2322 can be fixed in the through hole 221 in a relatively upright state. To facilitate the lead-out, two notches are provided at the bottom end of the through hole 221 of the insulating base 22, and the notches are provided at both sides of the rib 224 and below the flange 222. In order to prevent the lower end of the conductive lead 2322 from being fixed loosely and interfering with the position of the heating portion 231 of the heating element 23, the conductive lead 2322 is passed through the through hole 221, and then the fixing ring 25 is riveted to the lower end of the flange 222 of the insulating base 22, so that the conductive lead 2322 can be fixed firmly inside the through hole 221. Due to the fixing ring 25, the conductive leads 2322 do not need to be fixed in the through holes 221 by glue, and the operation is simpler and more convenient.
In a preferred embodiment, the heating portion 231 of the heating element 23 encloses a substantially tubular atomizing chamber that is not closed, and the central axes of the atomizing chamber, the receiving chamber 211 of the sleeve 21, and the through hole 223 of the insulating base 22 coincide with each other. During the installation of the atomizing assembly 20, the central axis can be precisely positioned by the substantially rod-shaped cotton swab. The outer diameter of the cotton packing rod is the same as the inner diameter of the through hole 223 of the insulating holder 22.
The liquid guiding element 24 is preferably made of cellucotton, and the liquid guiding element 24 is arranged at the periphery of the heating element 23 during installation. In some embodiments, the liquid guiding element 24 is composed of a plurality of liquid guiding cotton sheets, and after the plurality of liquid guiding cotton sheets are stacked together, the liquid guiding cotton sheets are enclosed on the periphery of the heating element 23, and two free sides of the liquid guiding cotton sheets are gathered to form a protruding structure 241, and the liquid guiding element 24 is fixed through the protruding structure 241. In other embodiments, the wicking element 24 is a thick wicking body, the wicking element 24 defines a hollow interior, and the heating element 23 is secured within the interior of the wicking element 24. On the side of the liquid guiding body, there is a raised structure 241, which raised structure 241 also facilitates the fixing of the liquid guiding element 24.
In order to facilitate easier fixing of fluid conducting element 24 having a certain thickness inside sleeve 21, U-shaped opening 212 is provided on sleeve 21 so that fluid conducting element 24 can be inserted into sleeve 21 through the side of U-shaped opening 212, and further, projection structure 241 on fluid conducting element 24 is fixed on U-shaped opening 212, and fluid conducting element 24 is in fluid communication with reservoir 13 through U-shaped opening 212. The sleeve 21 has a first end and a second end opposite to each other, the insulator base 22 is fixed to the second end of the sleeve 21, and the U-shaped opening 212 extends longitudinally to the second end of the sleeve 21. In some embodiments, and referring to FIG. 5, cannula 21 has first and second oppositely disposed openings 2121 and 2122, and first and second openings 2121 and 2122 are configured such that the second end of cannula 21 can be expanded at an angle to facilitate direct placement of cannula 21 over fluid conducting member 24.
The upper end of the liquid guiding element 24 is longitudinally abutted against the end part of the U-shaped opening 212 of the sleeve 21, and the lower end of the liquid guiding element 24 is longitudinally abutted against the upper end surface of the rib 224 of the insulating base 22. The width of the ribs 224 on the insulator base 22 is equal to the width of the opening 212 of the sleeve 21. The U-shaped opening 212 of the sleeve 21 extends longitudinally for a length configured to secure the raised structure 241 of the fluid-conducting element 24 and the first section of the rib 224 of the insulator base 22.

Secondly, inserting the first component from the U-shaped opening of the sleeve 21 until the protrusion 241 of the liquid guiding element 24 is clamped on the U-shaped opening 212 of the sleeve 21 to form a second component, as shown in fig. 8 b;
thirdly, aligning the raised structure 241 of the liquid guiding element 24 of the second component with the rib 224 of the insulating base 22 until the end of the second component abuts against the flange 222 of the insulating base 22 to form a third component, which is shown in fig. 8 c;
fourthly, riveting the fixing ring 25 on the insulating base 22 of the assembly 3, as shown in fig. 8 d; the fixing ring 25 presses the insulating base 22 during the riveting process to compress the conductive leads 2322, so that the conductive leads 2322 can be firmly located inside the through hole 221.
In addition, since each process of the above steps is basically positioned by the structure of the component itself, the full-automatic assembly can be realized, and the positioning hole 215 for fixing the fixture which is convenient for the automatic assembly can be arranged on the sleeve 21.
After assembly, the atomizing assembly 20 is mounted in the reservoir 131 inside the housing 10. After the liquid storage tube 131 is filled with enough liquid matrix, the cotton-covered rod 30 is taken out. In the whole assembling and assembling process of the atomizing assembly 20, the heating portion 231 of the heating element 23 is always wrapped on the cotton-covered rod 30, and the cotton-covered rod 30 can provide radial supporting force for the heating element 23, so that the position of the heating element 23 can be kept relatively stable.
The electrically conductive leads 2322 of the aerosol generating assembly 20 may be electrically connected directly to the battery 51 and the airflow sensing switch 52 inside the housing 10 of the aerosol generating device.
