Technical Field

[0001] This application relates to the field of airflow regulation technology, and in particular to an airflow regulation component, an atomizer, and an aerosol generating device. Background Technology

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. Driven by the power supply component, the atomizer atomizes the aerosol generating matrix stored in the reservoir, forming an aerosol for user use. In related technologies, users need to manually adjust the airflow within the atomizer, which is cumbersome and negatively impacts the user experience. Utility Model Content

[0003] In view of this, this application aims to provide an airflow regulating component, an atomizer, and an aerosol generating device. The airflow regulating component can adaptively adjust the airflow rate in the atomizer according to the user's inhalation resistance, which is beneficial to improving the user experience.

[0004] To achieve the above objectives, this application provides an airflow regulating component applied to an atomizer. The airflow regulating component includes an regulating part having a connecting channel that communicates with the air intake channel of the atomizer. The airflow regulating component includes a first state and a second state. In the first state, the airflow rate allowed to pass through the connecting channel is greater than the airflow rate allowed to pass through the connecting channel in the second state. The airflow regulating component can switch between the first state and the second state based on the air pressure of the air intake channel.

[0005] In one embodiment, at least a portion of the adjustment unit switches between the first state and the second state by undergoing elastic deformation.

[0006] In one embodiment, the connecting channel includes a main channel and an auxiliary channel, wherein the main channel is connected to the air intake channel;

[0007] In the first state, the airflow in the intake channel can enter the main channel from the auxiliary channel; in the second state, the airflow in the intake channel cannot enter the main channel from the auxiliary channel.

[0008] In one embodiment, the atomizer includes a main body and a housing disposed on the main body. The main body is provided with an air intake channel, and the housing is provided with a mounting channel communicating with the air intake channel. The adjustment part includes a sliding member, which is slidably disposed within the mounting channel.

[0009] A transition channel is provided between the circumferential sidewall of the sliding member and the sidewall of the mounting channel. The main channel is formed inside the sliding member, and the auxiliary channel is formed on the circumferential sidewall of the sliding member so that the main channel and the transition channel are connected. In the first state, the airflow in the air intake channel can be connected to the auxiliary channel through the transition channel.

[0010] In one embodiment, the housing has a stepped surface at one end of the mounting channel near the air intake channel, and in the second state, the sliding member is in a sealing fit with the stepped surface.

[0011] In one embodiment, the sliding member includes a first connecting segment and a second connecting segment connected to each other. The first connecting segment is disposed at one end of the second connecting segment near the air intake channel. In a cross-section perpendicular to the extension direction of the main channel, the cross-sectional dimension of the first connecting segment is smaller than that of the second connecting segment. The auxiliary channel is formed on the circumferential sidewall of the first connecting segment, and a transition channel is provided between the circumferential sidewall of the first connecting segment and the sidewall of the mounting channel.

[0012] In one embodiment, the adjusting part further includes an elastic element. In the first state, the sliding element moves away from the air intake channel under the action of air pressure, so that the elastic element undergoes elastic deformation; the elastic element recovers its elastic deformation, so that the sliding element moves towards the air intake channel under the action of elastic force.

[0013] In one embodiment, the airflow regulating assembly includes a connecting portion, the regulating portion including a plurality of elastic sheets, one end of each elastic sheet being connected to the connecting portion, and the other end extending toward the central axis of the connecting portion, so that the end of each elastic sheet away from the connecting portion surrounds the connecting channel;

[0014] The elastic sheet can undergo elastic deformation under air pressure, so that the end of the elastic sheet away from the connecting part is away from the central axis of the connecting part; the elastic sheet recovers its elastic deformation, so that the end of the elastic sheet away from the connecting part is close to the central axis of the connecting part.

[0015] This application provides an atomizer, including an air intake channel and an airflow regulating component as described in any of the above embodiments, wherein the connecting channel of the airflow regulating component is connected to the air intake channel.

[0016] This application provides an aerosol generating device, which includes a power supply component and an atomizer as described in any of the above embodiments, wherein the power supply component is electrically connected to the atomizer.

[0017] The airflow adjustment component provided in this application can automatically switch between two states based on the air pressure in the air intake channel. In other words, the airflow adjustment component can adaptively adjust the allowable airflow rate through the connecting channel according to the suction force, based on the air pressure in the air intake channel. When the user needs more aerosol, they can increase the suction force to switch the airflow adjustment component to the first state, increasing the allowable airflow rate and thus providing more aerosol, i.e., increasing the atomization volume. When the user needs to reduce the amount of aerosol obtained, they can decrease the suction force to switch the airflow adjustment component to the second state, reducing the allowable airflow rate and thus reducing the aerosol supply, i.e., decreasing the atomization volume. In this way, the airflow adjustment component can match the user's usage habits and adaptively adjust the airflow rate within the atomizer according to the user's suction resistance, without requiring additional user training, thus improving the user experience. Furthermore, the airflow adjustment component of this application does not require an external operating structure, which helps improve the aesthetics of the atomizer. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0027] In the description of this application, the orientation or positional relationship of "first direction" is based on the orientation or positional relationship shown in the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] This application provides an aerosol generating device, which includes a power supply component and an atomizer according to any one of the embodiments of this application. The power supply component is electrically connected to the atomizer.

[0029] The aerosol generating device is used to atomize an aerosol generating matrix to generate aerosols for user use. The aerosol generating matrix includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. In the embodiments of this application, the aerosol generating matrix can be a liquid material made primarily of plants (such as tobacco), with the addition of appropriate aerosol-forming agents and aroma materials.

[0030] The power supply component is electrically connected to the atomizer. The power supply component is mainly used to supply power to the atomizer and control the on / off operation of the entire aerosol generating device. Those skilled in the art should understand that the embodiments of this application do not specifically limit the type of aerosol generating device. For example, the aerosol generating device can be a medical nebulizer, an air humidifier, or an electronic cigarette, etc., that requires the use of an atomizer. This application embodiment provides an atomizer; please refer to [link to relevant documentation]. Figure 1 The atomizer 100 includes an air intake channel 30 and an airflow regulating component 10 in any embodiment of this application, and the connecting channel 11 is connected to the air intake channel 30.

[0031] For example, external airflow can flow into the atomizing chamber through the airflow regulating component 10 under the guidance of the air intake channel 30.

[0032] This application provides an airflow regulating component 10, which includes a regulating part 1 having a connecting channel 11 connected to the air inlet channel 30 of an atomizer. The airflow regulating component 10 includes a first state and a second state. In the first state, the airflow rate allowed through the connecting channel 11 is greater than the airflow rate allowed through the connecting channel 11 in the second state. The airflow regulating component 10 can switch between the first state and the second state based on the air pressure of the air inlet channel 30. Exemplarily, the atomizer has an atomizing chamber and an air outlet. An aerosol generating matrix generates aerosol in the atomizing chamber. The air outlet is connected to the atomizing chamber, and the aerosol generated in the atomizing chamber is discharged from the air outlet for user use.

[0033] The airflow regulating component 10 can be used to adjust the airflow rate within the connecting channel 11, thereby regulating the airflow rate entering the atomizing chamber from the air intake channel 30. For example, it can change the airflow rate by altering its own structure to meet the atomization effect requirements in different usage scenarios.

[0034] The regulating unit 1 has a connecting channel 11, which enables airflow regulation. The connecting channel 11 is used to connect to the air intake channel 30. The external airflow entering from the air intake channel 30 needs to pass through the connecting channel 11 and be regulated by the regulating unit 1 to change the airflow rate entering the atomizing chamber.

[0035] The structure of the connecting channel 11 is not limited here. For example, the inner wall of the connecting channel 11 is provided with a deformable flexible material, which changes the shape and size of the inner wall of the channel according to the change of air pressure, thereby realizing the dynamic adjustment of airflow.

[0036] The number of connection channels 11 is not limited here; for example, it can be one or more.

[0037] For example, multiple connecting channels 11 are provided to communicate with the air intake channel 30. By controlling the number of connecting channels 11, the airflow rate entering the atomizing chamber can be controlled. Of course, the overall airflow rate entering the atomizing chamber can also be controlled by controlling the airflow rate flowing into the atomizing chamber in each connecting channel 11.

[0038] The first and second states represent different operating states of the airflow regulating component 10. The connection channel 11 allows for a large airflow rate, suitable for scenarios requiring increased atomization. When the user needs more aerosol and increases the suction force, the suction resistance increases, the air pressure inside the atomizer 100 increases, and the airflow regulating component 10 enters the first state, increasing the airflow rate allowed through the connection channel 11, thereby increasing the aerosol supply.

[0039] In the second state, the airflow allowed through the connection channel 11 is small, which is suitable for scenarios where the amount of atomization is reduced. When the user does not need much aerosol and reduces the suction force, the suction resistance decreases, the air pressure inside the atomizer 100 decreases, and the airflow regulating component 10 enters the second state, thereby reducing the amount of aerosol supplied by reducing the airflow allowed through the connection channel 11.

[0040] In related technologies, atomizers have an adjustment mechanism that requires users to manually adjust the airflow size to regulate the amount of aerosol produced. This adjustment mechanism is cumbersome and negatively impacts the user experience. Furthermore, the adjustment handle is located on the product's exterior, affecting the e-cigarette's aesthetics.

[0041] The airflow adjustment component 10 provided in this embodiment can automatically switch between two states based on the air pressure of the air intake channel 30. In other words, the airflow adjustment component 10 can adaptively adjust the allowable airflow rate of the connecting channel 11 according to the suction force, based on the air pressure of the air intake channel 30. When the user needs more aerosol, the suction force is increased, the suction resistance increases, and the airflow adjustment component 10 switches to the first state, increasing the allowable airflow rate to provide more aerosol. When the user needs to reduce the amount of aerosol obtained, the suction force is decreased, the suction resistance decreases, and the airflow adjustment component 10 switches to the second state, reducing the allowable airflow rate to reduce the aerosol supply. The airflow adjustment component 10 can match the user's usage habits, adaptively adjusting the airflow rate within the atomizer 100 according to the user's suction resistance, without requiring additional user training, thus improving the user experience. Furthermore, the atomizer 100 of this application does not require an external operating structure, which improves the aesthetics of the atomizer 100.

[0042] In some embodiments, please refer to Figures 1 to 5 At least a portion of the adjustment unit 1 switches between a first state and a second state by undergoing elastic deformation.

[0043] Here, the adjustment unit 1 uses the elastic properties of the material to switch the working state of the airflow adjustment component 10.

[0044] For example, when the air pressure in the intake passage 30 changes, at least a portion of the regulating part 1 will undergo elastic deformation under the action of an external force (the force generated by the air pressure). This deformation will change the shape and / or size of the connecting passage 11, thereby changing the airflow rate allowed to pass through the connecting passage 11, and realizing the switching of the airflow regulating component 10 between the first state and the second state.

[0045] In some embodiments, the adjusting part 1 can change the size of the connecting channel 11 and the allowable airflow through the connecting channel 11 by elastic deformation. For example, when the user inhales forcefully, the air pressure in the air intake channel 30 increases, and the elastic part of the adjusting part 1 is deformed under pressure, making the connecting channel 11 wider and switching to the first state, increasing the airflow; conversely, when the air pressure decreases, the adjusting part 1 elastically recovers, the connecting channel 11 narrows, and switches to the second state, decreasing the airflow.

[0046] In other embodiments, the adjusting part 1 can change its position through elastic deformation to alter the fit between the connecting channel 11 and the intake channel 30, thereby changing the allowable airflow through the connecting channel 11. For example, the adjusting part 1 can generate a displacement through elastic deformation, changing the communication state between a portion of the connecting channel 11 and the intake channel 30, thus adjusting the allowable airflow through the connecting channel 11. In the first state, the adjusting part 1 moves to a state where the connecting channel 11 and the intake channel 30 are fully connected, maximizing the allowable airflow through the connecting channel 11, while the elastic portion of the adjusting part is deformed under pressure. Under the action of the elastic force, the adjusting part 1 moves to the second state where a portion of the connecting channel 11 is no longer connected to the intake channel 30, reducing the allowable airflow through the connecting channel 11.

[0047] By utilizing the elastic deformation of materials to achieve state switching, there is no need for complex mechanical transmission mechanisms, motors and other components, which reduces the number of parts and assembly complexity, and lowers production and manufacturing costs.

[0048] In some embodiments, please refer to Figures 1 to 4 The connecting channel 11 includes a main channel 111 and an auxiliary channel 112, with the main channel 111 connected to the intake channel 30. In a first state, the airflow within the intake channel 30 can enter the main channel 111 from the auxiliary channel 112. In a second state, the airflow within the intake channel 30 cannot enter the main channel 111 from the auxiliary channel 112.

[0049] The main channel 111 is directly connected to the intake channel 30, and the airflow can be guided within the main channel 111.

[0050] The auxiliary channel 112 works in conjunction with the main channel 111. In the first state, the auxiliary channel 112 can assist the main channel 111 in increasing the airflow. In the second state, the auxiliary channel 112 restricts the airflow.

[0051] For example, a movable baffle structure can be provided at the inlet of the auxiliary channel 112, and the opening and closing of the baffle can be controlled by air pressure or electromagnetic force. When the air pressure in the intake channel 30 reaches a certain threshold, the baffle opens, and the auxiliary channel 112 is open; when the air pressure decreases, the baffle closes automatically. In addition, an elastic seal can be added so that the auxiliary channel 112 is completely blocked in the second state to prevent air leakage.

[0052] For example, a multi-level auxiliary channel structure can be set up. For instance, a primary auxiliary channel, a secondary auxiliary channel, etc., can be set up, and the different levels of auxiliary channels can be opened or closed sequentially under different air pressure conditions. At low air pressure, only the main channel 111 works; at medium air pressure, the primary auxiliary channel is opened to assist; and at high air pressure, the secondary auxiliary channel also participates in airflow transmission, thereby achieving more precise airflow regulation.

[0053] The main channel 111 and the auxiliary channel 112 work together to adjust the airflow, matching the atomization volume requirements of different usage scenarios. Whether a large amount of atomization is needed (such as rapid aerosol replenishment) or a small amount of atomization (such as long-term low-intensity use), the appropriate airflow can be provided through state switching, which helps to improve the applicability of the atomizer 100.

[0054] In some embodiments, please refer to Figures 1 to 4 The atomizer 100 includes a main body and a housing 20 disposed on the main body. The main body is provided with an air intake channel 30, and the housing 20 is provided with a mounting channel 21 communicating with the air intake channel 30. The adjustment part 1 includes a slider 12, which is slidably disposed within the mounting channel 21. A transition channel 22 is formed between the circumferential sidewall of the slider 12 and the sidewall of the mounting channel 21. A main channel 111 is formed within the slider 12, and an auxiliary channel 112 is formed on the circumferential sidewall of the slider 12 so that the main channel 111 communicates with the transition channel 22. In a first state, the airflow in the air intake channel 30 can communicate with the auxiliary channel 112 through the transition channel 22.

[0055] The main body is provided with an air intake channel 30, which is used to guide airflow into the atomizer 100.

[0056] For example, the main body is provided with a columnar structure, and an air intake channel 30 is formed inside the columnar structure. The columnar structure can be connected and fitted to the outer shell so that the air intake channel 30 of the columnar structure communicates with the mounting channel 21 inside the outer shell 20.

[0057] The housing 20 is provided with a mounting channel 21 that communicates with the air intake channel 30 for mounting the adjustment unit 1.

[0058] In some embodiments, the housing 20 and the adjustment part 1 can be designed as a single component for manufacturing and assembly, allowing for separate quality inspection of this component, which helps improve quality inspection efficiency.

[0059] The mounting channel 21 is connected to the air intake channel 30 and can be used to provide space for the installation and sliding of the adjustment unit 1, so that the sliding member 12 can move therein and realize the airflow adjustment function.

[0060] In this embodiment, the adjustment unit 1 includes a slider 12, which can change the airflow path and flow rate by moving the slider 12. The slider 12 is slidably disposed in the mounting channel 21, and changes its relative positional relationship with the mounting channel 21 by sliding itself, thereby adjusting the airflow state.

[0061] The transition channel 22 is a gap channel formed between the circumferential sidewall of the sliding member 12 and the sidewall of the mounting channel 21, which serves to connect the intake channel 30 and the auxiliary channel 112. In the first state, the airflow in the intake channel 30 can enter the auxiliary channel 112 through the transition channel 22, thereby achieving airflow diversion and regulation.

[0062] The auxiliary channel 112 is a gas passage located on the circumferential side wall of the sliding member 12. It cooperates with the main channel 111 and the transition channel 22. In the first state, the auxiliary channel 112 is connected to the transition channel 22, and part of the airflow in the intake channel 30 can enter the main channel 111 in sequence through the transition channel 22 and the auxiliary channel 112, thereby increasing the airflow throughput and increasing the airflow rate. In the second state, the airflow in the intake channel 30 cannot flow from the transition channel 22 to the auxiliary channel 112, thereby restricting or blocking the airflow from the auxiliary channel 112 to the main channel 111, so as to reduce the airflow rate.

[0063] For example, the auxiliary channel 112 extends through the circumferential sidewall of the slider 12 along one radial side. The number of auxiliary channels 112 is not limited here; there may be one or more.

[0064] The arrangement of the multiple auxiliary channels 112 is not limited here. In some embodiments, each auxiliary channel 112 has another auxiliary channel 112 arranged symmetrically with the axis of the slider 12 as the axis of symmetry. In other embodiments, multiple auxiliary channels 112 are arranged along the axial direction of the slider 12.

[0065] In some embodiments, the slider 12 can be designed as a multi-layer nested structure. The main channel 111 inside the slider 12 remains unchanged, while multiple rotatable or sliding sleeves are provided on the outside. Each sleeve has auxiliary channels 112 of different specifications and numbers. By rotating or sliding the sleeves, the alignment and opening size of the auxiliary channels 112 with the transition channel 22 can be changed, thereby achieving airflow regulation.

[0066] In other embodiments, guide rails or grooves are provided on the inner wall of the mounting channel 21 to cooperate with the protrusions or grooves on the slider 12, making the sliding of the slider 12 smoother and more stable, reducing shaking and jamming. At the same time, limiting structures are provided at both ends of the mounting channel 21 to prevent the slider 12 from sliding out of the mounting channel 21, and elastic cushioning material is added at the limiting points to avoid the slider 12 from impacting and causing noise and damage.

[0067] By sliding the slider 12 within the mounting channel 21, the connection between the transition channel 22 and the auxiliary channel 112 can be controlled, enabling graded adjustment of the airflow. The switching process from low to high flow is smooth and stable, meeting the personalized needs of different users for atomization volume. By placing the slider 12 within the mounting channel 21 of the outer casing 20 and cooperating with the air intake channel 30 of the main body, the overall structure is compact, occupying little space, which is beneficial for the miniaturization design of the atomizer 100. Furthermore, in existing adjustment structures and airway connections, condensed condensate and e-liquid easily leak from the adjustment structure, contaminating the device's appearance and affecting the user experience. In this application, the slider 12 is placed within the mounting channel 21 of the outer casing 20, eliminating the need for external adjustment structures on the atomizer, thus improving the situation regarding condensate and e-liquid leakage.

[0068] In some embodiments, please refer to Figures 1 to 4 The outer casing 20 has a stepped surface 23 at one end of the mounting channel 21 near the air intake channel 30. In the second state, the sliding member 12 is sealed to the stepped surface 23.

[0069] The stepped surface 23 is a stepped surface structure formed by the outer shell 20 at the end of the mounting channel 21 near the air intake channel 30, used to cooperate with the sliding member 12. When the airflow regulating component 10 is in the second state (i.e., the state where the atomization volume needs to be reduced and the airflow volume needs to be limited), the sliding member 12 slides in the mounting channel 21 until it contacts the stepped surface 23, forming a sealing fit. This sealing fit can block the airflow from passing through the transition channel 22 and the auxiliary channel 112 between the sliding member 12 and the mounting channel 21, so that the airflow in the air intake channel 30 can only pass through the main channel 111 of the sliding member 12, thereby reducing the airflow volume, achieving low atomization output, and meeting the user's needs for the atomizer 100.

[0070] For example, an annular groove is formed on the stepped surface 23, and a rubber sealing ring is embedded therein. When the sliding member 12 contacts the stepped surface 23, the sealing ring is deformed by pressure, filling the gap between the two and achieving a seal.

[0071] In some embodiments, a positioning protrusion or positioning groove is provided in the installation channel 21 to cooperate with the positioning structure on the slider 12, so that the slider 12 can accurately seal with the step surface 23 in the second state.

[0072] In some embodiments, please refer to Figures 1 to 4 The sliding member 12 includes a first connecting section 121 and a second connecting section 122 connected to each other. The first connecting section 121 is disposed at one end of the second connecting section 122 near the intake passage 30. On a cross section perpendicular to the extension direction of the main passage 111, the cross-sectional dimension of the first connecting section 121 is smaller than that of the second connecting section 122. The auxiliary passage 112 is formed on the circumferential sidewall of the first connecting section 121. A transition passage 22 is provided between the circumferential sidewall of the first connecting section 121 and the sidewall of the mounting passage 21.

[0073] The first connecting section 121 is located at one end near the intake passage 30. During airflow regulation, the first connecting section 121 is used to guide airflow into the auxiliary passage 112 and the transition passage 22. For example, by contacting the stepped surface 23, the first connecting section 121 blocks the airflow in the intake passage 30 from entering the transition passage 22, thereby preventing the airflow from entering the main passage from the auxiliary passage 112.

[0074] The second connecting section 122 is connected to the first connecting section 121. Compared with the first connecting section 121, its cross-sectional dimensions are larger. Its main function is to cooperate with the first connecting section 121 to form the main channel 111. At the same time, the second connecting section 122 can slide with the installation channel 21, and the cooperation effect affects the stability of the overall structure.

[0075] The transition channel 22 here is located in the gap between the circumferential side wall of the first connecting section 121 and the side wall of the mounting channel 21, and serves to connect the intake channel 30 with the auxiliary channel 112 on the first connecting section 121.

[0076] Here, in a section perpendicular to the extension direction of the main channel 111, the cross-sectional dimension of the first connecting section 121 is smaller than that of the second connecting section 122. Thus, there can be a gap between the first connecting section 121 and the mounting channel 21 to form a transition channel 22.

[0077] The auxiliary channel 112 is disposed on the circumferential sidewall of the first connecting section 121, and a transition channel 22 is formed between the circumferential sidewall of the first connecting section 121 and the sidewall of the mounting channel 21. When the atomizer 100 is working, the relative positional relationship between the first connecting section 121, the auxiliary channel 112, and the transition channel 22 is changed by sliding the slider 12 within the mounting channel 21 in different working states. In the first state, the position of the slider 12 allows the airflow to sequentially pass through the transition channel 22 and the auxiliary channel 112 into the main channel 111, increasing the airflow rate; while in the second state, by blocking or restricting the connection between the auxiliary channel 112 and the transition channel 22, the airflow is transported solely through the main channel 111, thereby adjusting the airflow rate of the atomizer 100 to meet the needs of different usage scenarios.

[0078] In some embodiments, please refer to Figures 1 to 4 The adjustment unit 1 also includes an elastic member 13. In the first state, the sliding member 12 moves away from the air intake passage 30 under the action of air pressure, so that the elastic member 13 undergoes elastic deformation. The elastic member 13 restores its elastic deformation, so that the sliding member 12 moves towards the air intake passage 30 under the action of elastic force.

[0079] When the atomizer 100 is in the first state, the user's inhalation increases the air pressure in the air intake channel 30. Driven by this air pressure, the slider 12 moves away from the air intake channel 30. During this process, the elastic element 13 is compressed by the slider 12 and undergoes elastic deformation, storing elastic potential energy. When the user stops inhaling forcefully or reduces the inhalation force, the air pressure in the air intake channel 30 decreases. At this time, the elastic element 13 begins to release the stored elastic potential energy, generating elastic force through restoring its deformation. This elastic force acts on the slider 12, pushing it to move closer to the air intake channel 30, causing the airflow adjustment component 10 of the atomizer 100 to gradually switch to the second state, realizing automatic adjustment of the airflow from large to small, thereby adapting to different usage needs.

[0080] The structure of the elastic element 13 is not limited here. Depending on the force applied to the elastic element 13, it can be selected to include a compression spring or a tension spring. In addition to common compression springs, special-shaped springs such as wave springs and disc springs can be used to provide greater elastic force and deformation within the same space. Rubber elastomers, silicone elastic elements 13, etc. can also be used.

[0081] In some embodiments, a mounting base 14 is provided in the installation space away from the air intake channel 30, and a slider 12 is disposed between the mounting base 14 and the air intake channel 30. An elastic element 13 is a spring, disposed between the mounting base 14 and the slider 12, with both ends of the spring abutting against the mounting base 14 and the slider 12 respectively. The spring can be a compression spring. When the air intake pressure or suction pressure of the air intake channel 30 increases (i.e., the user's suction pressure at the air outlet increases, which means the pressure on the side of the slider 12 away from the air intake channel 30 increases), the slider 12 is pushed away from the air intake channel 30 by the air pressure, and the airflow regulating component 10 switches to the first state. At this time, the spring undergoes elastic deformation under pressure. When the air intake pressure or suction pressure of the air intake channel 30 decreases, the spring returns to its elastic deformation, pushing the slider 12 closer to the air intake channel 30, and the airflow regulating component 10 switches to the second state.

[0082] In other embodiments, the spring can be a tension spring, which operates on a principle largely the same as the previous embodiment. The difference is that, during the transition to the first state, the spring is stretched and undergoes elastic deformation.

[0083] The cooperation between the elastic element 13 and the sliding element 12 automates the airflow adjustment of the atomizer 100, eliminating the need for manual operation by the user. It automatically switches between different operating states based on changes in air pressure in the air intake channel 30 (i.e., the user's inhalation action), matching the user's desired atomization volume and improving ease of use and comfort. Compared to complex electric or pneumatically driven adjustment methods, the mechanical adjustment structure based on the elastic element 13 is simple, has fewer parts, lower manufacturing costs, and is easy to maintain, reducing user operating costs and equipment maintenance costs.

[0084] In some embodiments, the main body and the outer shell 20 are an integral structure.

[0085] By making the main body and the outer shell 20 an integral structure, it is beneficial to reduce the number of parts, improve assembly efficiency, and enhance the reliability of the connection structure between the main body and the outer shell 20. It also helps to reduce the airtightness between the main body and the outer shell 20.

[0086] In some embodiments, please refer to Figure 1 , Figures 5 to 6 The airflow regulating assembly 10 includes a connecting portion 15. The regulating portion 1 includes a plurality of elastic plates 16. One end of each elastic plate 16 is connected to the connecting portion 15, and the other end extends toward the central axis of the connecting portion 15, so that the end of each elastic plate 16 away from the connecting portion 15 forms a connecting channel 11. The elastic plate 16 can undergo elastic deformation under air pressure, so that the end of the elastic plate 16 away from the connecting portion 15 is away from the central axis of the connecting portion 15. The elastic plate 16 recovers its elastic deformation, so that the end of the elastic plate 16 away from the connecting portion 15 is close to the central axis of the connecting portion 15.

[0087] Please see Figure 5 or Figure 6 The central axis of the connecting part 15 is Figure 5 and Figure 6 The imaginary straight line shown at point L passes through the geometric center of the connecting part 15 and is perpendicular to the cross-section of the connecting part 15.

[0088] The elastic sheet 16 is a thin sheet component with elastic properties. It can deform under the action of external force (air pressure) and can return to its original shape after the external force is removed.

[0089] The adjusting section 1 consists of multiple elastic plates 16. One end of each elastic plate 16 is fixed to the connecting section 15, and the other end (the free end of the elastic plate) extends along the axis of the connecting section 15. In its natural state, the ends of the elastic plates 16 away from the connecting section 15 surround each other to form a connecting channel 11, which communicates with the intake channel 30, providing a flow path for airflow. The free ends of the elastic plates 16 can move radially along the connecting section 15.

[0090] For example, the central axes of the connecting channel 11, the air intake channel 30, and the connecting portion 15 coincide. When the air pressure in the air intake channel 30 changes (e.g., when the user inhales the atomizer 100), the air pressure acts on the elastic sheet 16, causing the elastic sheet 16 to undergo elastic deformation. The free end of the elastic sheet 16 moves radially away from the central axis L of the connecting portion 15, increasing the radial distance from the free end of the elastic sheet 16 to the central axis L of the connecting portion 15. This increases the flow cross-sectional area of ​​the connecting channel 11, thereby increasing the airflow.

[0091] When the air pressure decreases (e.g., when the user stops inhaling from the atomizer 100), the elastic sheet 16 recovers its deformation due to its elasticity. The free end of the elastic sheet 16 moves radially closer to the central axis L of the connecting portion 15, and the radial distance from the free end of the elastic sheet 16 to the central axis L of the connecting portion 15 decreases. In this way, the flow cross-sectional area of ​​the connecting channel 11 can be reduced, thus reducing the airflow volume.

[0092] The automatic adjustment of the airflow rate of the atomizer 100 is achieved through the dynamic deformation process of the elastic sheet 16.

[0093] The flow cross-sectional area here refers to the cross-sectional area perpendicular to the main flow direction along the fluid flow path, through which the fluid flows from one side to the other.

[0094] For example, the airflow regulating component 10 is a silicone part with a connecting portion 15. A thin wall is provided on one side of the connecting portion 15 to form the regulating portion 1. An airflow passage is formed at the center of the thin wall, and the size of the passage is determined according to the suction resistance of the atomizer. Several cuts are punched in the thin wall to connect to the central airflow passage, forming several easily deformable thin wall pieces, which are elastic sheets 16. The thin wall forms a connecting channel 11 communicating with the passage. When the suction is increased, the pressure of the airflow can pull the thin sheet open to a certain angle. The greater the suction force, the larger the cross-sectional area of ​​the connecting channel 11. The larger the cross-sectional area, the more airflow passes through, thus achieving adaptive adjustment of the airflow rate according to the suction force.

[0095] Utilizing the elastic deformation characteristics of the elastic sheet 16, it can quickly respond to changes in air pressure in the air intake channel 30 and automatically adjust the size of the connecting channel 11. This eliminates the need for complex mechanical transmissions or electronic control devices, enabling real-time, dynamic adjustment of airflow to meet the atomization needs of users under different suction intensities. The airflow adjustment component 10 mainly consists of the connecting part 15 and the elastic sheet 16, featuring a simple structure and few parts, reducing the risk of equipment damage due to component failure. The simple structural design reduces manufacturing difficulty and production costs, and facilitates maintenance.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
