[0030] The structure of the bottom air intake of some existing atomizers is quite complex and cumbersome. The bottom of the atomizer generally includes scattered parts such as a bracket, base, seal, circuit control device, and air adjustment pusher. The large number of parts makes manual assembly cumbersome, resulting in low installation efficiency and high molding costs.

[0031] Based on this, in order to solve the above problems, this application designs an atomizer that assembles the bracket, seal, circuit board, and gas regulating component into an integrated gas regulating module, forming a modular component that optimizes the internal structural layout of the atomizer. The main body of the seal is sealed between the circuit board and the bracket, and the support part of the seal is located on both sides of the circuit board and protrudes from the circuit board towards the air inlet. The gas regulating component is disposed between the support parts on both sides and slides directly with the support parts. The seal not only provides a sealing effect but also serves to slide and support the gas regulating component. By having a single component perform multiple functions, it is beneficial to simplify the product structure and reduce the number of parts.

[0032] refer to Figures 1 to 4 and Figure 7 This application provides an atomizer, including a housing 1 and an air regulating module 2 disposed within the housing 1. The housing 1 has an air inlet 101. The air regulating module 2 includes a bracket 4, a sealing member 5, a circuit board 6, and an air regulating component 3. The bracket 4 has an air tube 7. The circuit board 6 is connected to one end of the bracket 4 near the air inlet 101. The sealing member 5 includes a main body 510 disposed between the circuit board 6 and the bracket 4, and a support portion 520 protruding from both sides of the main body 510 toward the air inlet 101. The air tube 7 passes through the main body 510 and the circuit board 6 in sequence to communicate with the air inlet 101. The air regulating component 3 is slidably fitted on the support portion 520.

[0033] Specifically, the bracket 4 is disposed inside the housing 1 and can abut against the inner wall of the housing 1. Furthermore, the bracket 4 can be fixed to the housing 1, that is, the structures of the bracket 4 and the housing 1 are kept stable. The bracket 4 is used to install and fix the heating component, power supply component, etc. The circuit board 6 is connected to the end of the bracket 4 near the air inlet 101, which can provide stable support for the circuit board 6.

[0034] Understandably, the atomizer stores an aerosol matrix and also includes a heating element housed within the housing 1. The heating element is used to heat and atomize the aerosol matrix. One end of the air tube 7 is connected to the air inlet 101, and the other end is connected to the heating element. During inhalation, external gas flows sequentially through the air inlet 101, the air tube 7, and the heating element. The external gas mixes with the aerosol generated by the heating element and carries the aerosol to the atomizer's mouthpiece. The air regulating component 3 has an air intake structure, which adjusts the air intake by moving. External gas can sequentially enter the air tube 7 through the air inlet 101 on the housing 1 and the air intake structure of the air regulating component 3, ensuring smooth air intake. The main body 510 of the seal 5 is disposed between the circuit board 6 and the bracket 4, and can play a role in sealing, preventing leakage and shock absorption. Specifically, the main body 510 can improve the airtightness when air enters at the opening end of the air pipe 7, and prevent gas leakage. In addition, the main body 510 can prevent the condensate in the air pipe 7 from leaking into the circuit board 6, thereby improving product reliability. Furthermore, the main body 510 is disposed between the circuit board 6 and the bracket 4, and can form a flexible protection for the circuit board 6, thereby achieving a shock absorption and protection effect.

[0035] The air pipe 7 passes through the main body 510 and the circuit board 6 in sequence toward the air inlet 101 so as to be able to communicate with the outside air; and the air pipe 7 is installed in the main body 510 to ensure airtightness during the air intake process.

[0036] Understandably, the support portion 520 of the seal 5 is located on both sides of the circuit board 6 and the support portion 520 protrudes from the circuit board 6 towards the air inlet 101. Thus, the support portion 520 can be positioned and engaged with the circuit board 6, which facilitates the rapid assembly of the seal 5 and the circuit board 6.

[0037] The air regulating component 3 is disposed between the support portions 520 on both sides and slides with the support portions 520; that is, the sealing component 5 not only has a sealing effect, but also serves to slide support the air regulating component 3; thus, the sealing component 5 acts as a slide seat, eliminating the need for a separate slide seat structure, and enabling a single component to perform multiple functions, which helps to reduce the number of parts.

[0038] In this application, the atomizer, bracket 4, seal 5, circuit board 6, and gas regulating component 3 can be assembled into an integrated gas regulating module 2, forming a modular component that optimizes the internal structural layout of the atomizer. The gas regulating component 3 directly slides with the support part 520 of the seal 5. The seal 5 not only provides a sealing effect but also serves to slide and support the gas regulating component 3, undertaking multiple functions and simplifying the product structure and reducing the number of parts.

[0039] Furthermore, by pre-installing the gas regulating module 2, during product assembly, the modular gas regulating module 2 can be simply installed into the outer casing 1, effectively reducing assembly steps and lowering assembly difficulty and cost.

[0040] refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the main body 510 is provided with a first through hole 8, the circuit board 6 is provided with a second through hole 9, and the air pipe 7 is sequentially passed through the first through hole 8 and the second through hole 9; the air regulating component 3 has an air guiding structure 310 for connecting the air pipe 7 and the air inlet 101.

[0041] Specifically, the air pipe 7 is sequentially inserted into the first through hole 8 and the second through hole 9 in the direction of the air inlet 101 of the outer casing 1, so that the open end of the air pipe 7 can be exposed on the circuit board 6; the air regulating component 3 has an air guiding structure 310, and then the air inlet 101, the air guiding structure 310 and the air pipe 7 form an air passage for external gas to flow through.

[0042] Understandably, the first through hole 8 and the second through hole 9 are respectively provided on the main body 510 and the circuit board 6, which can also serve as a positioning tool. The air tube 7 passes through the main body 510 and the circuit board 6 to facilitate the quick assembly of the seal 5 and the circuit board 6 with the bracket 4.

[0043] The main body 510 is located between the bracket 4 and the circuit board 6 to provide sealing, prevent leakage, and damping.

[0044] refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the sealing member 5 further includes a protrusion 10 protruding on the side of the main body 510 near the circuit board 6. A through hole 11 is formed in the protrusion 10, which is opposite to and communicates with the first through hole 8. One end of the protrusion 10 away from the main body 510 abuts against the air regulating member 3, and the through hole 11 communicates with the air guiding structure 310.

[0045] Specifically, the diameter of the second perforation 9 is larger than that of the air tube 7, and part of the protrusion 10 fills the gap between the air tube 7 and the circuit board 6, which can form an effective sealing and isolation between the circuit board 6 and the air tube 7, preventing the atomizing liquid or condensate from entering the circuit board 6 and improving product reliability.

[0046] Understandably, the protrusion 10 has a through hole 11, through which external gas flows into the air pipe 7 via the air guide structure 310 on the air regulating component 3. The bottom end of the protrusion 10 abuts against the air regulating component 3, and when the gas flows from the air regulating component 3 to the air pipe 7, the protrusion 10 can prevent gas leakage, improve the airtightness between the air passages, and ensure rapid and smooth gas flow.

[0047] refer to Figures 4 to 7In some embodiments, a platform 410 is formed at one end of the bracket 4 near the air inlet 101, and a groove 420 is provided on the platform 410. The main body 510 is embedded in the groove 420; the circuit board 6 is connected to the platform 410; and part of the air pipe 7 is located in the groove 420.

[0048] Specifically, the main body 510 is embedded in the groove 420, and the circuit board 6 limits the main body 510 to prevent it from coming out of the groove 420; then, the sealing element 5 can be fixed at the same time simply by connecting the circuit board 6 to the bracket 4. The connection structure is simple and reliable; and the structure layout is compact with high space utilization, which is conducive to optimizing the volume of the atomizer.

[0049] Understandably, the wall platform 410 has a horizontal wall surface. After the main body 510 is embedded in the groove 420, the bottom surface of the main body 510 and the wall surface of the wall platform 410 form a support surface that contacts the circuit board 6. The circuit board 6 can fit tightly against the support surface, so that the stress of the circuit board 6 is evenly distributed when it is impacted, and the structural stability is enhanced.

[0050] For example, the circuit board 6 can be connected to the wall panel 410 by means of, but not limited to, screw connection, snap-fit, plug-in connection, etc.

[0051] It should be noted that there can be multiple circuit boards 6 used for circuit control in the atomizer, but in this embodiment, the circuit board 6 refers to the circuit board 6 that is horizontally arranged facing the air inlet 101. For example, a vertical circuit board can also be provided on the circuit board 6 in this embodiment, which is connected to the side of the bracket.

[0052] refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, a sliding part 12 is provided on one of the support part 520 and the air regulating component 3, and a slider sliding engagement part 13 is provided on the other of the support part 520 and the air regulating component 3; the sliding part 12 is slidably connected to the sliding engagement part 13.

[0053] Specifically, the support portion 520 extends from both sides of the main body portion 510 toward the air inlet 101 and protrudes from the circuit board 6; the air regulating component 3 is disposed between the support portions 520 on both sides, and forms a sliding fit with the support portion 520 through the sliding portion 12 and the sliding engagement portion 13. Furthermore, a sliding fit structure is provided between the air regulating component 3 and the sealing component 5, utilizing the structure of the sealing component 5 itself to provide sliding support for the air regulating component 3, eliminating the need for additional support parts, which helps to simplify the product structure, reduce the number of parts, and reduce processing and manufacturing costs.

[0054] refer to Figures 4 to 6In some embodiments, the support portion 520 includes a support pad 14 and a slide block 15 disposed on the bottom surface of the support pad 14; the sliding portion 12 includes a slide groove disposed on the slide block 15; the sliding engagement portion 13 includes a slider disposed on the air regulating member 3; the air regulating member 3 abuts against the bottom surface of the support pad 14 and causes the slider to slide into the slide groove.

[0055] The support pad 14 is set on the bottom surface of the main body 510 and protrudes from the circuit board 6; the air regulating component 3 is set between the two slides 15, the top surface of the air regulating component 3 is in contact with the bottom surface of the support pad 14, and the slider is set on both sides of the air regulating component 3, and the slider is slidably engaged in the slide groove of the slide 15.

[0056] The support pad 14 can isolate the gas regulating component 3 from the circuit board 6, preventing the gas regulating component 3 from directly contacting the circuit board 6. The gas regulating component 3 will slide along the bottom surface of the support pad 14.

[0057] Understandably, the circuit board 6 is a relatively delicate component. The support pad 14 isolates the gas regulating component 3 from the circuit board 6, preventing the sliding movement of the gas regulating component 3 from damaging the electrical structure of the circuit board 6. The support pad 14 is part of the sealing component 5 and is made of flexible material. The support pad 14 can provide flexible protection for the bottom surface of the circuit board 6, while the main body 510 can provide flexible protection for the top surface of the circuit board 6, effectively protecting both sides of the circuit board 6 and improving product reliability.

[0058] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the air guiding structure 310 includes a plurality of air holes provided on the air regulating member 3.

[0059] Understandably, external gas enters the air tube 7 through the air vents. By controlling the sliding of the air regulating component 3, the number of air vents connected to the air tube 7 can be adjusted. The more air vents connected to the air tube 7, the greater the air intake of the atomizer; the fewer air vents connected to the air tube 7, the smaller the air intake of the atomizer 100. Furthermore, when there are no air vents on the air regulating component 3 connected to the air tube 7, the atomizer is in a closed air intake state, meaning that external gas will not enter the atomizer 100. Under the action of the sealing component 5, an effective airtightness can be formed at the air inlet 101 of the atomizer, preventing the intrusion of external liquids and improving the sealing performance of the product.

[0060] In some embodiments, reference Figures 1 to 7 In some embodiments, the air regulating component 3 is also provided with a push button 16, which is located inside the air inlet 101.

[0061] Specifically, the push button 16 is located inside the air inlet 101 and is convenient for the user to operate by hand. By controlling the push button 16 to slide in the air inlet 101, the air regulating component 3 is moved to adjust the number of air holes on the air regulating component 3 that are connected to the air pipe 7.

[0062] In some embodiments, the main body 510 and the support 520 are an integrated structure.

[0063] The sealing element 5 of this application is a flexible sealing material, such as rubber or silicone. For example, the main body 510 and the support 520 can be integrally molded by injection molding, which has good structural integrity and is easy to process and mold.

[0064] Understandably, the main body 510 is located between the circuit board 6 and the bracket 4, providing airway sealing, leak prevention, and shock absorption, effectively preventing liquid from the atomizer's interior from leaking into the circuit board 6; and providing flexible protection for the circuit board 6. The support 520 is located between the circuit board 6 and the air regulating component 3, preventing direct contact between the air regulating component 3 and the circuit board 6, and providing flexible protection for the circuit board 6. Furthermore, this application adopts a modular design for the bracket 4, sealing component 5, circuit board 6, and air regulating component 3, taking into account both effective protection of the circuit board 6 and simplifying the product structure while ensuring product reliability.

[0065] refer to Figures 3 to 6 In some embodiments, the circuit board 6 is provided with an electrical connector 17, and the main body 510 is provided with a connection hole 18 through which the power supply connector 17 passes.

[0066] Understandably, the electrical connector 17 passes through the connection hole 18, and the main body 510 can form an effective seal for the electrical connector 17; it can prevent the atomized liquid or corrosive gas in the atomizer from seeping back into the circuit board 6, thus avoiding short circuits or component corrosion.

[0067] refer to Figure 1 and Figure 2 The second aspect of this application also provides an aerosol generating apparatus, including a power supply component and the atomizer described above.

[0068] Understandably, the atomizer of this application is specifically used in an aerosol generating device, wherein the atomizer stores an aerosol matrix and also includes a heating component. The power supply component supplies power to the heating component, causing the heating component to heat up and atomize the aerosol matrix.

[0069] For example, the power supply assembly is housed within the housing 1 and can be mounted on the bracket 4; alternatively, the power supply assembly can also be mounted on other support structures within the atomizer. In some embodiments, the aerosol generating device includes a circuit board assembly, which is electrically connected to a heating component and a power supply component. The circuit board assembly controls the heating power and temperature of the heating component by outputting stable electricity to stabilize the atomization effect. The circuit board assembly includes at least the circuit board 6 in the embodiments of this application. The circuit board assembly may include multiple circuit boards, with different circuit boards used to implement different electrical controls (such as the output power of the power supply component, the heating power of the heating component, etc.). In the embodiments of this application, the circuit board 6 refers to the circuit board 6 that is horizontally arranged facing the air inlet 101.

[0070] Understandably, the aerosol generating device of this application can be an aerosol generating device with a replaceable atomizer, i.e., the atomizer and power supply assembly are detachably connected. Alternatively, the aerosol generating device of this application can also be a disposable aerosol generating device, i.e., the atomizer and power supply assembly are not detachably connected; no specific limitation is made here.

[0071] The application does not specify the model of the atomizer, that is, the shape of the atomizer can be wine pot-shaped, rectangular, cylindrical, etc.

[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
