[0035] An aerosol generating device is a small device that can use the heat not burn (Heat Not Burning, HNB) technology to act on an aerosol generating matrix and generate an aerosol. Specifically, the aerosol generating device usually heats the aerosol generating matrix to a temperature that can generate aerosol but is not high enough to burn, so that the aerosol generating matrix can generate an aerosol for the user to inhale without burning. The aerosol generating device can ensure the original taste of the aerosol generating matrix and effectively control the production of harmful substances. As people pay more and more attention to health, aerosol generating devices have gradually become people's first choice. However, in current aerosol generating devices, the heating element usually heats the bottom or circumference of the aerosol generating matrix, the heated area of the aerosol generating matrix is small, and the heating efficiency of the aerosol generating matrix is low. In order to solve this problem, the embodiment of the present application provides an atomizer 100 ( Figure 2 ) and aerosol generating device 1000 ( Figure 1 shown).

[0036] See also Figures 1 to 4 The atomizer 100 of the embodiment of the present application includes a bracket 20, a storage element 10, and a heating element 30. The storage element 10 is mounted on the bracket 20 and is provided with an opening 11. The storage element 10 includes a peripheral wall 13 and a bottom wall 15 connected to each other. The bottom wall 15 is opposite to the opening 11. The bottom wall 15 of the storage element 10 includes a first sub-portion 151, a second sub-portion 153, and a third sub-portion 155 connecting the first sub-portion 151 and the second sub-portion 153. In the longitudinal direction X of the atomizer 100, the second sub-portion 153 is closer to the opening 11 than the first sub-portion 151. The second sub-portion 153 and the third sub-portion 155 together form a first cavity 17. The bottom wall 15 and the peripheral wall 13 together form a second cavity 19. The bottom wall 15 separates the first cavity 17 and the second cavity 19. The second cavity 19 is used to load the aerosol generating substrate. The heating element 30 is mounted on the bracket 20 and at least partially extends into the first cavity 17 . The heating element 30 is used to heat the aerosol-generating substrate in the second cavity 19 .

[0037] See also Figure 1 and Figure 2 Specifically, the atomizer 100 of the present application is provided in an aerosol generating device 1000 and is configured to be powered to heat an aerosol-generating substrate, thereby generating an aerosol for inhalation by a user. The atomizer 100 may heat the aerosol-generating substrate by, but is not limited to, infrared heating, resistive heating, microwave heating, electromagnetic heating, or laser irradiation heating.

[0038] See also Figure 1 The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating substrate. Aerosols may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol generating substrate is a product that has been processed and heated to generate an aerosol. The aerosol generating substrate may be in a liquid state, a fully solid state, or a semi-solid state. In the case where the aerosol generating substrate is solid, the aerosol generating substrate may be a smoking paste that, when heated, generates an aerosol for the user to inhale.

[0039] The aerosol generating device 1000 of the present embodiment further includes a battery assembly 300, and the atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 can be used to power the heating element 30, so that the heating element 30 can heat the aerosol generating substrate, so that the aerosol generating substrate can generate aerosol.

[0040] See also Figure 3 and Figure 4, the bracket 20 is a structure for mounting the storage element 10, the heating element 30 and other components of the atomizer 100. The storage element 10 and the heating element 30 can be mounted directly on the bracket 20, or the storage element 10 and the heating element 30 can be mounted on the bracket 20 through other components, so that the storage element 10, the heating element 30 and the bracket 20 can be fixedly connected to prevent the storage element 10 and the heating element 30 from loosening or falling off relative to the bracket 20. The bracket 20 of the present application is conductive, and the bracket 20 is used to electrically connect the battery assembly 300 and the heating element 30, so that the battery assembly 300 can supply power to the heating element 30. The outer wall of the lower end of the bracket 20 is provided with a thread, and the bracket 20 is connected to the battery assembly 300 through the thread, so that the atomizer 100 can be mounted on the battery assembly 300.

[0041] Please combine Figure 6 and Figure 7 The storage element 10 is a structure for storing an aerosol-generating substrate. The opening 11 is used to allow the aerosol-generating substrate to be loaded into the second chamber 19. At least a portion of the bottom wall 15 of the storage element 10 is recessed toward the opening 11 to form a first chamber 17, which is used to accommodate the heating element 30. With the bottom wall 15 separating the first chamber 17 and the second chamber 19, the first chamber 17 and the second chamber 19 are not connected, preventing the aerosol-generating substrate in the second chamber 19 from leaking out.

[0042] See also Figures 3 to 5 When powered, the heating element 30 is used to heat the storage element 10 and the aerosol-generating substrate in the second cavity 19. When the aerosol-generating substrate needs to be heated, the battery assembly 300 supplies power to the heating element 30, which heats the second subsection 153 and the third subsection 155. The second subsection 153 and the third subsection 155 can then transfer heat to the aerosol-generating substrate in the second cavity 19. The aerosol-generating substrate absorbs the heat to generate aerosol.

[0043] The second subsection 153 and the third subsection 155 can form a columnar structure, with the aerosol-generating substrate within the second cavity 19 surrounding the columnar structure. When the heating element 30 heats the second subsection 153 and the third subsection 155, both the second subsection 153 and the third subsection 155 can transfer heat to the aerosol-generating substrate. This increases the heated area of the aerosol-generating substrate, resulting in more efficient heating of the aerosol-generating substrate and a better puffing experience for the user.

[0044] Currently commonly used microwave-heated aerosol generating devices 1000, electromagnetic-heated aerosol generating devices 1000, and plasma-heated aerosol generating devices 1000 are all relatively large, making them inconvenient for users to carry. In the aerosol generating device 1000 of the present application, the projections of the first cavity 17 and the second cavity 19 in a plane perpendicular to the longitudinal direction X of the atomizer 100 overlap, and the projections of the first cavity 17 and the second cavity 19 in a plane perpendicular to the longitudinal direction X of the atomizer 100 also overlap. When the heating element 30 is installed in the first cavity 17, the overall volume of the atomizer 100 is relatively small, and thus the aerosol generating device 1000 is relatively small, making it easier for users to carry.

[0045] Current resistive heating aerosol generating devices 1000 typically use bottom heating or circumferential heating for the aerosol generating substrate. Under these heating methods, the heating of various locations on the aerosol generating substrate is uneven, resulting in a poor puffing experience for the user. In the aerosol generating device 1000 of the present embodiment, the heating element 30 heats the aerosol generating substrate via the second subsection 153 and the third subsection 155. This allows for more uniform heating of various locations on the aerosol generating substrate, resulting in a finer aerosol produced after the heating of the aerosol generating substrate and a better puffing experience for the user.

[0046] In the atomizer 100 of the embodiment of the present application, in the longitudinal direction X of the atomizer 100, the second sub-portion 153 is closer to the opening 11 than the first sub-portion 151. The second sub-portion 153 and the third sub-portion 155 together form a first cavity 17, and the bottom wall 15 and the peripheral wall 13 together form a second cavity 19. The heating element 30 in the first cavity 17 can heat the second sub-portion 153 and the third sub-portion 155. Both the second sub-portion 153 and the third sub-portion 155 can transfer heat to the aerosol-generating substrate in the second cavity 19. This increases the heated area of the aerosol-generating substrate, resulting in higher heating efficiency and a better puffing experience for the user.

[0047] The atomizer 100 will be further described below with reference to the accompanying drawings.

[0048] See also Figures 3 to 6 In some embodiments, the surface of the heating element 30 is coated with an infrared coating, and the heating element 30 is used to generate infrared light when powered. The second sub-section 153 and the third sub-section 155 can be heated by the infrared light and allow the infrared light to pass through.

[0049] Among them, the heating element 30 may include a heating body and an infrared coating. When the battery assembly 300 supplies power to the heating element 30, the heating body can generate heat to heat the infrared coating, so that the infrared coating can emit infrared light. The infrared coating can increase the radiation penetration efficiency of a specific wavelength, so that the heating efficiency of the aerosol generating matrix is higher. The heating element 30 of the present application is a spiral heating element 30. The spiral structure can increase the surface area of the heating element 30, thereby increasing the emission area of infrared light. The heating efficiency of the heating element 30 for the second sub-section 153 and the third sub-section 155 is higher, so that the heating efficiency of the aerosol generating matrix is higher.

[0050] When the heating element 30 emits infrared light, it can heat the second and third subsections 153, 155, thereby transferring heat from the second and third subsections 153, 155 to the aerosol-generating substrate within the second cavity 19, thereby heating the aerosol-generating substrate. Furthermore, the infrared light can penetrate the second and third subsections 153, 155 and enter the second cavity 19, thereby heating the aerosol-generating substrate. This dual heating of the aerosol-generating substrate results in a higher heating efficiency.

[0051] In one embodiment, the second subsection 153 and the third subsection 155 are capable of absorbing infrared light and generating heat. They are also capable of allowing infrared light to pass through and enter the second cavity 19. The second subsection 153 and the third subsection 155 can be made of transparent quartz. Preferably, the wavelength of the infrared light generated by the heating element 30 matches the transparent quartz, allowing the second subsection 153 and the third subsection 155 to be quickly heated. Heat from the second subsection 153 and the third subsection 155 is transferred to the aerosol-generating substrate, heating it and generating aerosol. Infrared light can also penetrate the transparent quartz and enter the second cavity 19, heating the aerosol-generating substrate. In this case, the peripheral wall 13 of the storage element 10 and the third subsection 155 may not be permeable to infrared light and cannot be heated by infrared light, allowing for greater flexibility in the choice of materials for the peripheral wall 13 of the storage element 10 and the third subsection 155.

[0052] In another embodiment, the storage element 10 is entirely a transparent quartz tube. The storage element 10 can absorb infrared light emitted by the heating element 30 and generate heat, which can be transferred to the aerosol-generating substrate. The storage element 10 also allows infrared light to enter the second cavity 19, so that the infrared light can heat the aerosol-generating substrate. In this case, the infrared light can enter the second cavity 19 to heat the aerosol-generating substrate. Moreover, while the second sub-section 153 and the third sub-section 155 are heated and transfer heat to the aerosol-generating substrate, the peripheral wall 13 of the storage element 10 and the first sub-section 151 of the bottom wall 15 can also be heated by the infrared light and transfer heat to the aerosol-generating substrate. This improves the heating efficiency of the aerosol-generating substrate, and the heating of each position of the aerosol-generating substrate is more uniform. The aerosol produced after the aerosol-generating substrate is heated is more delicate, and the user's puffing experience is better.

[0053] See also Figure 4 and Figure 5 In other embodiments, the heating element 30 may be a resistance wire, and the storage element 10 may be a heat conductor. The second sub-section 153 and the third sub-section 155 are capable of transferring heat from the heating element 30 to the aerosol-generating substrate. In this case, the storage element 10 may be an alumina tube or a zirconia ceramic tube. The storage element 10 has a high thermal conductivity. After the heating element 30 is energized and generates heat, the heat from the heating element 30 can be transferred to the second sub-section 153 and the third sub-section 155. In turn, the second sub-section 153 and the third sub-section 155 can transfer the heat to the aerosol-generating substrate, causing the aerosol-generating substrate to generate aerosol.

[0054] See also Figures 3 to 5 Furthermore, in some embodiments, the atomizer 100 further includes a first reflector 40 , which surrounds the peripheral wall 13 , and is configured to reflect the infrared light penetrating the peripheral wall 13 back into the second cavity 19 .

[0055] At this time, the first reflector 40 can reuse the infrared light. The infrared light reflected back into the second cavity 19 can heat the aerosol generating matrix again, and the heating efficiency of the aerosol generating matrix is relatively high. Due to the small overall size of the aerosol generating device 1000, when the heating element 30 heats the aerosol generating matrix, the outer wall of the aerosol generating device 1000 easily heats up, resulting in a poor user experience. The first reflector 40 of the present application can also prevent the heat in the second cavity 19 from being transferred outward, thereby effectively reducing the temperature of the outer wall of the atomizer 100, and providing a better user experience.

[0056] The first reflector 40 of this application is a gold-plated stainless steel member. When infrared light strikes the surface of the first reflector 40, the electron cloud on the metal surface interacts with the photons. Due to the high reflectivity of the gold plating and the good conductivity of the stainless steel substrate, most of the infrared light energy is absorbed and re-emitted as photons, forming infrared reflected light. This infrared reflected light then enters the second cavity 19 and continues to heat the aerosol-generating substrate.

[0057] See also Figures 3 to 5 Furthermore, in some embodiments, the atomizer 100 also includes a second reflector 41, which is connected to the first reflector 40 and covers the bottom wall 15. The second reflector 41 is used to reflect the infrared light penetrating the bottom wall 15 back into the second cavity 19.

[0058] At this point, the second reflector 41 allows the infrared light that penetrates the first subsection 151 to be reused. The infrared light reflected back into the second cavity 19 can reheat the aerosol-forming substrate, resulting in a high heating efficiency. Furthermore, the second reflector 41 prevents heat from being transferred outward, thereby effectively reducing the temperature of the outer wall of the atomizer 100 and providing a better user experience. The second reflector 41 of the present application is also a gold-plated stainless steel component, so that the second reflector 41 can effectively reflect infrared light.

[0059] Preferably, the second reflector 41 and the first reflector 40 are interference fit to form a closed reflective cavity. When the infrared light in the second cavity 19 penetrates the storage element 10 and enters the reflective cavity, the first reflector 40 and the second reflector 41 can effectively reflect the infrared light back into the second cavity 19, thereby preventing the infrared radiation in the reflective cavity from being emitted from between the first reflector 40 and the second reflector 41. The heating efficiency of the aerosol generating matrix is high, and the temperature of the outer wall of the atomizer 100 can be effectively reduced.

[0060] See also Figures 3 to 5 In some embodiments, the atomizer 100 further includes a fixing member 50, which is mounted on the second reflector 41 and connected to the heating element 30. The fixing member 50 is fixedly mounted on the second reflector 41 and is located between the bottom wall 15 of the storage element 10 and the second reflector 41. The fixing member 50 is used to fix the heating element 30 to prevent the heating element 30 from shaking relative to the storage element 10. The material of the fixing member 50 can be zirconium oxide ceramics and polyetheretherketone (PEEK) with low thermal conductivity, so that the fixing member 50 can effectively prevent the heat of the storage element 10 from being transferred outward, and the user experience is better.

[0061] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 8Furthermore, in some embodiments, the atomizer 100 also includes a heat insulating member 60, which is mounted on the bracket 20 and is sleeved on the peripheral wall 13 of the first reflector 40 and the peripheral wall 13 of the second reflector 41. The heat insulating member 60 is used to further prevent the heat inside the storage member 10 from being transferred outward, which can avoid the problem of high temperature of the outer wall of the atomizer 100, and the user experience is better. The material of the heat insulating member 60 can be zirconium oxide ceramics and polyetheretherketone (PEEK) with low thermal conductivity. The heat insulating member 60 of the present application is mounted on the bracket 20, the first reflector 40 and the second reflector 41 are mounted on the heat insulating member 60, and the storage member 10 is mounted in the reflection cavity surrounded by the first reflector 40 and the second reflector 41.

[0062] See also Figures 3 to 5 In some embodiments, the atomizer 100 further includes a nozzle assembly 70, which is connected to the storage component 10, and a first magnetic component 71 is provided at one end of the nozzle assembly 70 close to the thermal insulation component 60; a through hole 61 is provided at one end of the thermal insulation component 60 close to the nozzle assembly 70, and a second magnetic component 63 is provided in the through hole 61. The first magnetic component 71 and the second magnetic component 63 cooperate to connect the nozzle assembly 70 to the thermal insulation component 60.

[0063] The nozzle assembly 70 is detachably connected to the opening 11 of the storage element 10. When a user uses the aerosol generating device 1000, the battery assembly 300 supplies power to the heating element 30, which heats the aerosol generating substrate to generate aerosol. The user can inhale the aerosol generated in the atomizer 100 through the nozzle 75.

[0064] When the nozzle assembly 70 is connected to the storage element 10, the first magnetic member 71 and the second magnetic member 63 attract each other, ensuring a relatively stable connection between the nozzle assembly 70, the storage element 10, and the thermal insulation member 60. This prevents the nozzle assembly 70 from falling relative to the storage element 10. To add aerosol-generating substrate to the storage element 10, the user can simply apply a certain amount of force to remove the nozzle assembly 70 from the storage element 10. This makes it relatively simple for users to insert and remove the nozzle assembly 70, providing a better user experience.

[0065] In one embodiment, the first magnetic member 71 is a structure that can magnetically attract other elements through its own magnetic field. For example, the first magnetic member 71 can be a magnet. The second magnetic member 63 is an element that can be magnetized in a magnetic field. For example, the second magnetic member 63 can be a ferromagnetic material such as iron, nickel, and cobalt. In this case, when the nozzle assembly 70 is connected to the storage element 10, the second magnetic member 63 is located within the magnetic field of the first magnetic member 71 and is magnetized, so that the first magnetic member 71 and the second magnetic member 63 can be attracted to each other. In another embodiment, the second magnetic member 63 is a structure that can magnetically attract other elements through its own magnetic field. For example, the second magnetic member 63 can be a magnet. The first magnetic member 71 is an element that can be magnetized in a magnetic field. For example, the first magnetic member 71 can be a ferromagnetic material such as iron, nickel, and cobalt. In this case, when the nozzle assembly 70 is connected to the storage element 10, the first magnetic member 71 is located within the magnetic field of the second magnetic member 63 and is magnetized, so that the first magnetic member 71 and the second magnetic member 63 can be attracted to each other. In another embodiment, the first magnetic member 71 and the second magnetic member 63 are both structures that can magnetically attract other components through their own magnetic fields. For example, the first magnetic member 71 and the second magnetic member 63 can both be magnets. In this case, when the nozzle assembly 70 is connected to the storage element 10, the first magnetic member 71 is located within the magnetic field of the second magnetic member 63, and the second magnetic member 63 is also located within the magnetic field of the first magnetic member 71, and the first magnetic member 71 and the second magnetic member 63 can attract each other.

[0066] The first magnetic member 71 of the present application is a stainless steel member, and the second magnetic member 63 is a magnet.

[0067] See also Figure 2 and Figure 3 In some embodiments, the atomizer 100 further includes a decorative member 90, which is sleeved onto the outer wall of the heat insulator 60, the outer wall of the bracket 20, and the outer wall of the first magnetic member 71. The decorative member 90 not only decorates the nozzle assembly 70 and the heat insulator 60, but also enhances the overall aesthetics of the atomizer 100. Furthermore, the decorative member 90 is configured to achieve an interference fit with both the bracket 20 and the heat insulator 60, thereby ensuring a more stable connection between the bracket 20 and the heat insulator 60 and preventing loosening of the connection between the bracket 20 and the heat insulator 60.

[0068] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 9In some embodiments, in the length direction X of the atomizer 100, the heat insulation member 60 is provided with a first air channel 65 running through two opposite ends; the nozzle assembly 70 includes a sealing member 73 and a nozzle 75, and the sealing member 73 and the nozzle 75 are both connected to the first magnetic member 71, and the sealing member 73 is connected to the storage member 10 and the nozzle 75. The sealing member 73 includes a main body 731 and a connecting portion 733 extending from the main body 731, and at least a portion of the connecting portion 733 extends into the second cavity 19. The main body 731 is provided with a second air channel 7311, and the connecting portion 733 is provided with a channel 7331 running through two opposite ends. The second air channel 7311 connects the first air channel 65 and the channel 7331, and the channel 7331 is connected to the second cavity 19.

[0069] Among them, the first magnetic part 71 is also used to connect the sealing part 73 and the suction nozzle 75 so that the sealing part 73 and the suction nozzle 75 are fixedly connected. When the user applies external force to the suction nozzle 75, the suction nozzle 75 can drive the sealing part 73 and the first magnetic part 71 to be removed from the storage part 10 together.

[0070] The nozzle 75 is located at the top end of the atomizer 100. The nozzle 75 is provided with a perforation 753 that communicates with the outside world. The perforation 753 is used to allow the aerosol to flow out of the atomizer 100 for inhalation by the user. The user can inhale the aerosol through the nozzle 75. In the longitudinal direction X perpendicular to the atomizer 100, at least a portion of the nozzle 75 corresponds to the storage element 10. At least a portion of the sealing member 73 is located between the storage element 10 and the nozzle 75. The sealing member 73 is used to seal the gap between the storage element 10 and the nozzle 75 to prevent the aerosol generated by the heated aerosol-generating substrate from flowing out of the gap between the storage element 10 and the nozzle 75, thereby avoiding waste of the aerosol. The material of the sealing member 73 includes, but is not limited to, silicone or rubber.

[0071] See also Figure 4 When a user draws on the aerosol generating device 1000, ambient air enters the battery assembly 300 and flows into the first air passage 65. The air then flows through the second air passage 7311 and into the second chamber 19 via the channel 7331. The air entering the second chamber 19 can then carry the aerosol through the perforation 753 and out of the mouthpiece 75 for inhalation by the user. Preferably, along the longitudinal direction X of the atomizer 100, the first air passage 65 and the second air passage 7311 correspond to each other, allowing ambient air entering the first air passage 65 to quickly pass through the second air passage 7311 and into the channel 7331.

[0072] The main body 731 is used to connect with the first magnetic member 71 and the suction nozzle 75, and to seal the gap between the storage member 10 and the suction nozzle 75. At least a portion of the connecting portion 733 extends into the second cavity 19, so that the external gas flowing out of the channel 7331 can be fully mixed with the aerosol and carry the aerosol out of the suction nozzle 75, which can avoid the problem of insufficient fusion of gas and aerosol. The main body 731 and the connecting portion 733 are an integral structure or a split structure. The main body 731 and the connecting portion 733 of the present application are an integral structure, so that the processing steps of the sealing member 73 are relatively simple. The suction nozzle assembly 70 is also provided with a shielding member, which is connected to the main body 731 and is used to block the communication between the channel 7331 and the perforation 753. During the user's inhalation, the external air in the second air channel 7311 can enter the second cavity 19 through the channel 7331 , thereby preventing the external air in the second air channel 7311 from directly flowing out of the atomizer 100 through the perforation 753 .

[0073] See also Figure 3 、 Figure 4 、 Figure 8 and Figure 9 Furthermore, in some embodiments, the inner wall of the suction nozzle 75 is provided with a third air channel 751, and in the longitudinal direction X of the vertical atomizer 100, the third air channel 751 corresponds to and is connected to the second air channel 7311. At this time, in the longitudinal direction X of the vertical atomizer 100, the depth dimension of the air channel formed by the second air channel 7311 and the third air channel 751 is relatively large, and the volume of external gas flowing through the second air channel 7311 and the third air channel 751 per unit time is relatively large. During the user's inhalation process, the external gas can quickly enter the second cavity 19 and merge with the aerosol, and then the external gas carries the aerosol out of the atomizer 100 from the suction nozzle 75, and the user's inhalation experience is better.

[0074] See also Figure 3 、 Figure 5 、 Figure 9 and Figure 10 In some embodiments, the main body 731 further defines a through-hole 7313 spaced apart from the second air passage 7311. The through-hole 7313 communicates with the second chamber 19. The mouthpiece 75 further defines a fourth air passage 755, which connects the through-hole 7313 and the through-hole 753. After ambient air mixes with the aerosol in the second chamber 19, the ambient air carries the aerosol through the through-hole 7313 and flows into the fourth air passage 755. The ambient air and aerosol entering the fourth air passage 755 then flow through the through-hole 753 to the exterior of the atomizer 100 for inhalation by the user.

[0075] The main body 731 is provided with a second air channel 7311 and a through hole 7313 spaced apart from each other to separate the outside air entering the atomizer 100 and the aerosol flowing out of the atomizer 100. The aerosol generating device 1000 does not require any additional separators, which facilitates the miniaturization of the aerosol generating device 1000.

[0076] See also Figures 3 to 5 In some embodiments, the atomizer 100 further includes an electrical connector 80, which is mounted on the bracket 20 via a mounting member 81. The bracket 20 is electrically connected to one electrode of the heating element 30, and the electrical connector 80 is electrically connected to another electrode of the heating element 30. The electrical connector 80 is provided with a fifth air channel 83 and a branch hole 85 that are connected to each other. The branch hole 85 connects the fifth air channel 83 and the first air channel 65.

[0077] The electrical connector 80 is used to electrically connect the battery assembly 300 and the heating element 30. The electrical connector 80 and the heating element 30 can be electrically connected via a wire, and the bracket 20 and the heating element 30 can also be electrically connected via a wire. When the electrical connector 80 is electrically connected to the positive electrode of the heating element 30, the bracket 20 is electrically connected to the negative electrode of the heating element 30, thereby achieving an electrical connection between the heating element 30 and the battery assembly 300, and the battery assembly 300 can supply power to the heating element 30. When the electrical connector 80 is electrically connected to the negative electrode of the heating element 30, the bracket 20 is electrically connected to the positive electrode of the heating element 30, thereby achieving an electrical connection between the heating element 30 and the battery assembly 300, and the battery assembly 300 can supply power to the heating element 30.

[0078] The mounting member 81 is used to securely mount the electrical connector 80 within the bracket 20. The mounting member 81 also insulates the electrical connector 80 from the bracket 20 to prevent short circuits between the electrical connector 80 and the bracket 20. The mounting member 81 may be made of, but is not limited to, rubber or silicone.

[0079] The number of sub-holes 85 can be, but is not limited to, two, three, four, or more. The present application provides four sub-holes 85, so that the gas in the fifth airway 83 can quickly pass through the sub-holes 85 into the first airway 65. When a user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300. Gas enters the fifth airway 83 from the interior of the battery assembly 300 and enters the first airway 65 through the four sub-holes 85. The gas then flows through the second airway 7311 and into the second cavity 19 through the passage 7331. The gas entering the second cavity 19 can carry aerosol through the sub-holes 85 and into the fourth airway 755. The gas and aerosol entering the fourth airway 755 then flow through the perforations 753 to the outside of the atomizer 100 for inhalation by the user.
