[0002] In aerosol generation devices, precise airflow regulation is crucial. It directly affects the quality and efficiency of aerosol generation, as well as the user experience. Therefore, many aerosol generation devices are currently equipped with airflow regulators specifically designed for fine-tuning the airflow. These regulators can be broadly categorized into active and passive types. Active airflow regulators are typically more complex in structure and require manual adjustment by the user.

[0003] Passive air conditioning units can adaptively adjust based on the user's suction habits and force. However, because aerosols in the airflow channel of the aerosol generator tend to adhere to the air conditioning unit, its airflow regulation function is reduced. Summary of the Invention

[0006] The air regulating component includes a fixed end and a free end. The fixed end is connected to the side wall of the airflow channel, and the free end extends into the airflow channel so that the air regulating component at least partially closes the airflow channel. The free end can be elastically offset relative to the fixed end to change the closed area of ​​the airflow channel.

[0007] The air regulating component is tilted from the fixed end to the free end toward the airflow direction of the airflow channel.

[0008] Optionally, the aerosol generating device includes multiple gas regulating components arranged circumferentially along the airflow channel to form a conical structure facing the airflow direction.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] The aerosol generating apparatus provided in the embodiments of this application will now be described. Please refer to... Figure 1 and Figure 2 In some embodiments of this application, the aerosol generating device includes an airflow channel 10 and an air regulating component 1 disposed on the airflow channel 10;

[0043] The air regulating component 1 includes a fixed end 11 and a free end 12. The fixed end 11 is connected to the side wall of the airflow channel 10, and the free end 12 extends into the airflow channel 10 so that the air regulating component 1 at least partially closes the airflow channel 10. The free end 12 can be elastically offset relative to the fixed end 11 to change the closed area of ​​the airflow channel 10.

[0044] The air regulating component 1 is inclined from the fixed end 11 to the free end 12 toward the airflow direction of the airflow channel 10.

[0045] Aerosol generating devices typically utilize atomizing components 104 to atomize the aerosol generating matrix, thereby generating aerosols for users to inhale or use. The aerosol generating device is equipped with an airflow channel 10 for airflow. During device operation, air or other gases enter from the inlet, flow along the airflow channel 10, and interact with other components during the flow, such as carrying atomized aerosols through the atomization area, ultimately flowing out from the outlet for user use.

[0046] The air regulating component 1 is disposed on the airflow channel 10 to regulate the airflow in the airflow channel 10. The fixed end 11 of the air regulating component 1 is connected to the side wall of the airflow channel 10, which serves to fix the air regulating component 1, keep the air regulating component 1 in a stable position in the device, and provide a support basis for the movement of the free end 12. The free end 12 of the air regulating component 1 extends into the airflow channel 10. Opposite to the fixed end 11, the free end 12 can elastically offset relative to the fixed end 11. Because it extends into the airflow channel 10, it can affect the flow of air in the airflow channel 10, and change the closed area of ​​the airflow channel 10 through elastic deformation, thereby regulating the airflow.

[0047] like Figure 2 As shown, the arrows indicate the airflow direction. The air regulating component 1 is tilted from its fixed end 11 to its free end 12 towards the airflow direction of the airflow channel 10, and its tilt direction from the fixed end 11 to the free end 12 is consistent with the airflow direction in the channel. This tilting design helps the air regulating component 1 better sense the force of the airflow and more effectively adjust its elastic displacement according to the airflow, thereby more precisely adjusting the closed area of ​​the airflow channel 10. When the airflow impacts the air regulating component 1, because its tilt direction is the same as the airflow direction, the airflow acts more smoothly on the free end 12, making it easier for the free end 12 to elastically deflect, thus solving the problem of reduced airflow regulation function of the air regulating component 1 due to the adhesion of liquid. At the same time, when the air regulating component 1 is opened to the same degree, the elastic displacement angle of the free end 12 is smaller, which better maintains a larger opening.

[0048] Please see Figure 3 In some embodiments of this application, the aerosol generating device includes a plurality of gas regulating components 1, which are arranged circumferentially along the airflow channel 10 to form a conical structure facing the airflow direction.

[0049] In this embodiment, multiple air regulating components 1 are distributed circumferentially along the airflow channel 10, forming a conical structure. This conical structure guides the airflow. The opening of the conical structure faces the airflow direction, allowing the airflow to be effectively guided and concentrated when entering the airflow channel 10. The airflow flows along the inner wall of the conical structure, gradually converging towards the center. This guiding effect prevents turbulence and eddies in the airflow within the channel, allowing the airflow to pass through the airflow channel 10 more smoothly. Simultaneously, the conical structure also accelerates the airflow. As the airflow flows from the larger opening to the smaller opening of the conical structure, the airflow velocity gradually increases due to the gradually decreasing cross-sectional area of ​​the channel, according to the principle of fluid continuity. This increases the kinetic energy of the airflow, making it easier for the air regulating components 1 to open.

[0050] Please see Figure 3 In some embodiments of this application, the airflow channel 10 includes an initial airflow channel 20, and a plurality of air regulating components 1 are arranged circumferentially along the initial airflow channel 20 so that a plurality of free ends 12 surround the initial airflow channel 20.

[0051] The airflow channel 10 includes an open initial airflow channel 20 through which airflow can first pass, forming an initial breakthrough point. This reduces the difficulty of opening the air regulating component 1 due to adhesion or other reasons. The initial airflow channel 20 is actually formed by the circumferential free ends 12. When the airflow passes through the initial airflow channel 20, it simultaneously impacts the free ends 12 of each air regulating component 1. Because the free ends 12 are elastic, they will elastically deflect under the impact of the airflow, thereby changing the closed area of ​​the initial airflow channel 20. This design cleverly utilizes the impact force of the airflow to regulate the airflow itself, reducing the difficulty of opening the air regulating component 1.

[0052] Please see Figure 2 In some embodiments of this application, the thickness of the air regulating component 1 gradually decreases from the fixed end 11 to the free end 12. The fixed end 11 is thicker, while the free end 12 is thinner. The thicker fixed end 11 can better withstand these forces and maintain good elasticity after multiple deformations, preventing the air regulating component 1 from being damaged or falling off from the fixed point. The thinner free end 12 allows it to deform to a certain extent under relatively small airflow pressure, thereby ensuring the sensitivity of airflow adjustment. In addition, the thinner free end 12 can effectively reduce mutual adhesion caused by liquid adhesion. This is because the thinner free end 12 has a smaller area available for liquid adhesion, thereby reducing the possibility of adhesion between multiple free ends 12.

[0053] In some embodiments of this application, the thickness of the air regulating component 1 is 0.1 mm to 0.5 mm. This ensures that the air regulating component 1 has sufficient strength to withstand airflow pressure while maintaining a certain degree of elasticity to achieve the airflow regulation function. The material of the air regulating component 1 can be silicone, rubber, or polyurethane. Silicone has good elasticity, high and low temperature resistance, chemical stability, and is non-toxic and odorless; rubber has good elasticity, sealing performance, wear resistance, and fatigue resistance; polyurethane has high strength, good elasticity, oil and solvent resistance, and its hardness and flexibility can be adjusted according to requirements. Currently, silicone is the most commonly used of these three materials. Medical-grade silicone can be used, which has good biocompatibility and will not cause harm to human health, ensuring user safety.

[0054] Please see Figure 4 and Figure 5 In some embodiments of this application, the aerosol generating apparatus includes:

[0055] Bottom cover 2; Bottom cover 2 is provided with a first air hole 21;

[0056] Atomizing component 104; Atomizing component 104 is provided with a second air hole 1041;

[0057] Isolation bracket 4; Isolation bracket 4 is disposed between atomizing component 104 and bottom cover 2. Isolation bracket 4 is provided with third air hole 41. First air hole 21, second air hole 1041 and third air hole 41 are connected to form airflow channel 10.

[0058] The fixed end 11 is connected to the isolation bracket 4, and the free end 12 extends into the airflow channel 10 so that the air regulating component 1 at least partially closes the third air hole 41.

[0059] In this embodiment, the aerosol generating device consists of main components such as a bottom cover 2, an atomizing component 104, and an isolation bracket 4. The first air hole 21 on the bottom cover 2 is the starting end of the entire airflow channel 10, responsible for guiding external air into the device. The atomizing component 104 is provided with a second air hole 1041, which is the key area for aerosol generation. The airflow passing through this area carries the atomized substance. The isolation bracket 4 is located between the atomizing component 104 and the bottom cover 2, and its third air hole 41 connects the first air hole 21 and the second air hole 1041, so that the three are connected to form a complete airflow channel 10.

[0060] The fixed end 11 of the air regulating component 1 is connected to the isolation bracket 4, and the free end 12 extends into the airflow channel 10 and at least partially closes the third air hole 41. This arrangement allows the air regulating component 1 to directly regulate the airflow passing through the third air hole 41. This installation method of the air regulating component 1 ensures its stability and enables its free end 12 to effectively act on the airflow, thereby achieving airflow control.

[0061] In some embodiments, the aerosol generating device further includes a nozzle 101, a housing assembly 102, a liquid storage chamber assembly 103, an atomizing assembly 104, and a battery assembly 105. The liquid storage chamber assembly 103 has an atomizing chamber and a liquid storage chamber, which are connected by a liquid guiding structure. The atomizing assembly 104 is located in the atomizing chamber. The battery assembly 105 is connected to the liquid storage chamber assembly 103. The nozzle 101 is snap-fitted to the housing assembly 102, and an oil-absorbing assembly 106 is also provided at the nozzle 101. The bottom cover 2 and the fixing base 3 form the basic airflow channel 10 structure, ensuring that external airflow can enter the device in an orderly manner. The nozzle 101, as the part that the user directly contacts, is snap-fitted to the housing assembly 102. This connection method is convenient for installation and disassembly, facilitates later maintenance, and ensures structural stability. The oil-absorbing assembly 106 provided at the nozzle 101 can effectively prevent liquid in the liquid storage chamber from entering the oral cavity with the airflow during use, improving the user experience and safety.

[0062] The outer casing 102 not only provides protection for the internal components but also influences the overall appearance and portability of the device. The liquid storage chamber 103 is a key component, containing an atomizing chamber and a liquid storage chamber connected by a liquid guiding structure. The liquid storage chamber stores liquid raw materials, and the liquid guiding structure precisely controls the flow of liquid to the atomizing chamber, providing a stable supply of raw materials for the atomization process. Driven by power supplied by the battery assembly 105, the atomizing component 104 within the atomizing chamber converts the liquid entering the chamber into an aerosol. The battery assembly 105, connected to the liquid storage chamber 103, not only powers the atomizing component 104 but also works in conjunction with the entire device's circuitry to ensure the orderly operation of all components. Its power reserve and power supply stability directly affect the device's battery life and performance.

[0063] In some embodiments of this application, the isolation bracket 4 and the gas regulating component 1 are integrally molded structures. The integral molding structure of the isolation bracket 4 and the gas regulating component 1 means that there is no traditional connection method between them. This completely eliminates problems such as loosening, detachment, and air leakage that may occur at the connection points. During the operation of the aerosol generating device, the impact of airflow and the vibration of the device may affect the connection points, but the integral molding structure avoids these potential hazards, greatly improving the stability and reliability of the device structure. The material of the isolation bracket 4 can also be silicone, rubber, or polyurethane.

[0064] The one-piece molding process integrates the isolation bracket 4 and the air regulating component 1 into a single unit, resulting in greater consistency in material continuity and mechanical properties. Compared to assembled structures, the one-piece molded components can better withstand external forces, especially when airflow impacts the air regulating component 1. The entire structure can distribute stress more evenly, reducing localized stress concentrations. This helps extend the service life of the components and improve the overall durability of the device.

[0065] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the isolation bracket 4 includes a bracket body 42 and a protrusion 43. The protrusion 43 is connected to the bracket body 42, and the third air hole 41 is located inside the protrusion 43 and penetrates the bracket body 42. The fixed end 11 is connected to the protrusion 43, and the free end 12 is located inside the third air hole 41.

[0066] In this embodiment, the isolation bracket 4 is mainly composed of a bracket body 42 connected to a protrusion 43, with a third air hole 41 disposed within the protrusion 43 and penetrating the bracket body 42. The fixed end 11 of the air regulating component 1 is connected to the protrusion 43, ensuring the overall stable installation of the air regulating component 1. The free end 12 is located within the third air hole 41, receiving multifaceted protection. From a physical perspective, the third air hole 41 prevents the free end 12 from being damaged by accidental collisions inside the device. During device operation, internal components may shift due to vibration. If the free end 12 is exposed, it is highly susceptible to friction or collision with other components, leading to deformation or even damage, affecting the air regulating function of the air regulating component 1. However, within the third air hole 41, the free end 12 is effectively isolated, greatly reducing such risks.

[0067] From the perspective of airflow influence, the third vent 41 has a certain rectifying effect on the incoming airflow. When the airflow enters from the first vent 21 of the bottom cover 2 and flows through the third vent 41 to the second vent 1041 of the atomizing component 104, the airflow direction and speed are regulated to a certain extent during the process of passing through the third vent 41. This avoids the turbulent airflow from generating excessive impact force on the free end 12, prevents the free end 12 from being excessively deformed due to abnormal airflow impact, and thus ensures that the free end 12 can always work within a suitable elastic deformation range, maintaining the accuracy of airflow regulation.

[0068] Please see Figure 4 and Figure 5 In some embodiments of this application, the aerosol generating device further includes a main board 5, which is electrically connected to the atomizing component 104; the main board 5 is disposed between the isolation bracket 4 and the bottom cover 2, and a positioning hole is provided on the main board 5, with the protrusion 43 passing through the positioning hole.

[0069] In this embodiment, the mainboard 5 and the atomizing component 104 are electrically connected. The mainboard 5 provides power to the atomizing component 104 and controls its operating state. The mainboard 5 is positioned between the isolation bracket 4 and the bottom cover 2. This placement is based on several considerations. Firstly, placing the mainboard 5 in this position makes full use of the internal space of the device, resulting in a more compact and rational layout of the components. Secondly, this position allows the isolation bracket 4 to separate the atomizing component 104 from the mainboard 5, preventing the atomizing component 104 from interfering with the normal operation of the mainboard 5.

[0070] The positioning hole on the motherboard 5 mates with the protrusion 43 of the isolation bracket 4, with the protrusion 43 passing through the positioning hole. This design provides precise positioning, ensuring the accurate position of the isolation bracket 4 within the device. During assembly, the isolation bracket 4 can be installed quickly and accurately by inserting the protrusion 43 into the positioning hole, improving assembly efficiency. The accurate installation of the isolation bracket 4 ensures the positional accuracy of the third air vent 41, thereby guaranteeing the normal operation of the airflow channel 10.

[0071] Please see Figure 1 and Figure 5 In some embodiments of this application, the isolation bracket 4 further includes a resiliently compressible latching portion 44, which is disposed outside the protrusion 43 and latches onto the side of the motherboard 5 opposite to the isolation bracket 4. The latching portion 44 of the isolation bracket 4 has the characteristic of being resiliently compressible. This means that it can undergo elastic deformation when subjected to external force and can return to its original shape when the external force is removed. This elastic characteristic allows the latching portion 44 to directly forcefully pass the protrusion 43 through the motherboard 5 when engaging with the motherboard 5, thereby achieving latching.

[0072] In some embodiments of this application, the isolation bracket 4 includes a plurality of snap-fit ​​portions 44, which are spaced apart circumferentially along the protrusion 43. This makes the snap-fit ​​portions 44 easier to compress, thereby improving assembly convenience.

[0073] Please see Figure 4 and Figure 5 In some embodiments of this application, the aerosol generating device includes a fixed base 3, a main board 5 connected to the fixed base 3, and a fourth air hole 31 provided on the fixed base 3; a positioning groove 32 is provided on the fixed base 3 along the circumference of the fourth air hole 31, and a protrusion 43 abuts against the positioning groove 32 so that the third air hole 41 and the fourth air hole 31 are connected.

[0074] In this embodiment, the mounting base 3 provides an important structural support for the entire aerosol generation device. The main board 5 is connected to the mounting base 3, giving it a stable mounting position within the device. This helps ensure the stability of the electronic components and circuitry on the main board 5 during device operation, avoiding problems such as poor electrical connections or component damage caused by shaking or displacement, thereby ensuring the stable and reliable electrical performance of the device. The fourth air hole 31 on the mounting base 3 is connected to the third air hole 41 on the isolation bracket 4, ensuring airflow.

[0075] The positioning groove 32, which is circumferentially arranged on the fixed base 3 along the fourth air hole 31, cooperates with the protrusion 43 of the isolation bracket 4. The protrusion 43 abuts against the positioning groove 32, and this design plays a role in precise positioning. It ensures that the isolation bracket 4 is accurately positioned on the fixed base 3, so that the third air hole 41 and the fourth air hole 31 can be precisely aligned and connected, thereby ensuring that the airflow can pass smoothly through these two air holes without obstruction or leakage due to positional deviation.

[0076] Please see Figure 4 and Figure 5 In some embodiments of this application, the aerosol generating device further includes a sealing element 6; an annular groove 22 is provided on the bottom cover 2, and the sealing element 6 is disposed in the annular groove 22; the fixing seat 3 includes an annular flange 33, a fourth air hole 31 is disposed in the annular flange 33, the annular flange 33 is disposed in the annular groove 22, and abuts against the sealing element 6.

[0077] In this embodiment, the annular groove 22 on the bottom cover 2 is a mounting position for the seal 6. The size and shape of the annular groove 22 are adapted to the seal 6, precisely accommodating it and maintaining its stable position within the device. The seal 6 is disposed within the annular groove 22 and is typically made of a material with good elasticity and sealing properties, such as rubber or silicone. Its function is to fill the gap between the bottom cover 2 and the fixing seat 3, preventing airflow leakage from the connection point. During device operation, the seal 6 can withstand a certain amount of pressure and deformation, maintaining a good sealing state and ensuring that airflow can only flow along the predetermined airflow channel 10.

[0078] The annular flange 33 of the fixing seat 3 corresponds to the annular groove 22 of the bottom cover 2, and the fourth vent 31 is disposed within the annular flange 33. The annular flange 33 is disposed within the annular groove 22 and abuts against the sealing element 6. This structural design makes the connection between the fixing seat 3 and the bottom cover 2 tighter. The annular flange 33 applies a certain pressure to the sealing element 6, causing it to undergo elastic deformation, further filling the tiny gaps in the connection area and enhancing the sealing effect.

[0079] Please see Figure 5The isolation bracket 4 has a receiving groove 45 on the side facing the atomizing assembly 104, and an adsorption element 7 is installed in the receiving groove 45. This design provides specific installation space for the adsorption element 7. The adsorption element 7 can be made of materials such as oil-absorbing cotton, inorganic fibers, or porous materials, possessing good adsorption properties. Its main function is to adsorb any liquids that may appear, preventing them from leaking onto the gas regulating component 1. In the aerosol generating device, liquid may overflow when the atomizing assembly 104 is operating, or liquid may flow when the device is tilted. If the liquid comes into contact with the gas regulating component 1, it may affect the performance of the gas regulating component 1, for example, changing its elastic characteristics, making it unable to accurately adjust the closed area of ​​the airflow channel 10, thus affecting aerosol generation and the normal operation of the device. The adsorption element 7 can absorb these liquids in a timely manner, thus protecting the gas regulating component 1.

[0080] 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.
