Description

Technical Field

[0001] This application belongs to the technical field of aerosol generating equipment, and more specifically, relates to an aerosol generating device. Background Technology

[0002] With the continuous improvement of living standards, aerosol generators, especially portable ones, have rapidly entered households due to their convenience and practicality, gaining widespread popularity and expanding in market share. In the structural design of aerosol generators, buttons, as key components for controlling core functions such as starting, stopping, and switching modes, directly impact production efficiency, manufacturing costs, and user experience. Currently, the mainstream button design for aerosol generators generally adopts a combination structure of "pre-installed buttons on the outer shell + silicone buffer assembly." The core design concept is to reserve button mounting holes in the corresponding control area of ​​the outer shell, first installing the rigid button body (usually made of plastic) into the mounting holes, and then, to prevent noise caused by rigid collisions with the outer shell or internal structure during pressing, an additional silicone buffer is installed on the inside of the button or at the pressing contact end. The elastic deformation properties of silicone absorb the pressing impact, thereby eliminating button noise and improving the pressing feel.

[0003] However, after long-term production practice and market feedback verification, the above-mentioned existing button design has many insurmountable drawbacks in practical applications, specifically as follows: Firstly, increased assembly time leads to higher manufacturing costs. Since the buttons and silicone buffers are two independent components, a separate "button and silicone buffer pairing assembly" process is required in the production assembly flow. Operators must align the silicone buffers with the button's mounting points (such as slots, bosses, etc.) one by one for installation and fixation. This process not only consumes additional labor time but also requires control over assembly accuracy (to prevent misalignment of the silicone buffers from affecting the buffering effect), directly extending the production time of a single machine and significantly increasing both labor and time costs.

[0004] Secondly, the secondary assembly process further increases costs. After the buttons and silicone cushioning components are paired and assembled, the entire assembly must be inserted into the button mounting holes on the equipment housing. Compared to "direct assembly of single components," this process requires a higher degree of coordination in the assembly operation—ensuring that the buttons, silicone cushioning components, and housing mounting holes in the assembly are perfectly aligned to avoid assembly jamming due to the elastic deformation of the silicone cushioning components. This further increases assembly time, making the production process more complex and indirectly increasing the overall manufacturing cost of the product.

[0005] Thirdly, the silicone cushioning component is prone to detachment, posing a risk of equipment malfunction. During the assembly of the "button-silicone" combination into the housing, the silicone cushioning component is only connected to the button via simple mechanical means (such as snap-fits or interference fits), resulting in limited fixing strength. During assembly, friction or pressure from the housing mounting holes, or improper handling by the operator, can easily cause the silicone cushioning component to detach from the button. Once detached, the button not only loses its cushioning function and produces noticeable pressing noises, but the detached silicone component may also become stuck between the button and the internal circuit board, preventing the button from triggering properly (e.g., no response when pressed, button sticking). This directly leads to abnormal equipment operation, severely impacting product reliability and user experience, and may even increase after-sales repair rates, further increasing the company's operating costs. Utility Model Content

[0006] The purpose of this application is to provide an aerosol generating device that addresses the technical problems of low production efficiency, high manufacturing cost, and poor functional stability in the prior art.

A second spring arm is provided on the housing, and the position of the second spring arm corresponds to the position of the first spring arm. The second spring arm can be bent toward the press trigger when subjected to force, so that the second spring arm pushes the first spring arm to bend toward the press trigger.

[0017] The beneficial effects of the aerosol generator provided in this application are as follows: Compared with the prior art, the aerosol generator provided in this application forms a linkage triggering structure through a first spring arm on the frame and a second spring arm on the outer shell. When the linkage triggering structure is pressed, the second spring arm can push the first spring arm to elastically bend together to trigger the pressing trigger. The linkage triggering structure eliminates the need for purchasing and assembling independent silicone buffer components, simplifies the assembly process of the aerosol generator, and reduces the production cost of the aerosol generator. Furthermore, the linkage triggering structure can also absorb impact energy through the elastic deformation of the first and second spring arms, achieving buffering and noise reduction in the triggering process. While avoiding abnormal pressing noise, it provides a soft and sensitive pressing feel, thereby improving the reliability and user experience of the aerosol generator. Attached Figure Description

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.

[0024] As described in the background section, with the continuous improvement of living standards, aerosol generators, especially portable aerosol generators, have rapidly entered thousands of households due to their convenience and practicality, gaining widespread popularity in the market and experiencing continuous expansion in usage. In the structural design of aerosol generators, buttons, as key components for controlling core functions such as device start / stop and mode switching, directly affect the product's production efficiency, manufacturing costs, and user experience through their assembly structure and operational stability. Currently, the mainstream button design schemes for aerosol generators on the market generally adopt a combination structure of "pre-installed buttons on the outer shell + silicone buffer assembly." The core design concept is as follows: button mounting holes are reserved in the corresponding control area of ​​the device shell. The rigid button body (usually made of plastic or similar materials) is first installed into the mounting holes in the shell. Then, to prevent abnormal noise caused by rigid collisions between the button and the shell or internal structure during pressing, a silicone buffer is additionally installed on the inside of the button or at the pressing contact end. The elastic deformation properties of silicone absorb the pressing impact, thereby eliminating button noise and improving the pressing feel.

[0025] However, after long-term production practice and market feedback verification, the above-mentioned existing button design has many insurmountable drawbacks in practical applications, specifically as follows: Firstly, increased assembly time leads to higher manufacturing costs. Since the buttons and silicone buffers are two independent components, a separate "button and silicone buffer pairing assembly" process is required in the production assembly flow. Operators must align the silicone buffers with the button's mounting points (such as slots, bosses, etc.) one by one for installation and fixation. This process not only consumes additional labor time but also requires control over assembly accuracy (to prevent misalignment of the silicone buffers from affecting the buffering effect), directly extending the production time of a single machine and significantly increasing both labor and time costs.

[0026] Secondly, the secondary assembly process further increases costs. After the buttons and silicone cushioning components are paired and assembled, the entire assembly must be inserted into the button mounting holes on the equipment housing. Compared to "direct assembly of single components," this process requires a higher degree of coordination in the assembly operation—ensuring that the buttons, silicone cushioning components, and housing mounting holes in the assembly are perfectly aligned to avoid assembly jamming due to the elastic deformation of the silicone cushioning components. This further increases assembly time, making the production process more complex and indirectly increasing the overall manufacturing cost of the product.

[0027] Thirdly, the silicone cushioning component is prone to detachment, posing a risk of equipment malfunction. During the assembly of the "button-silicone" combination into the housing, the silicone cushioning component is only connected to the button via simple mechanical means (such as snap-fits or interference fits), resulting in limited fixing strength. During assembly, friction or pressure from the housing mounting holes, or improper handling by the operator, can easily cause the silicone cushioning component to detach from the button. Once detached, the button not only loses its cushioning function and produces noticeable pressing noises, but the detached silicone component may also become stuck between the button and the internal circuit board, preventing the button from triggering properly (e.g., no response when pressed, button sticking). This directly leads to abnormal equipment operation, severely impacting product reliability and user experience, and may even increase after-sales repair rates, further increasing the company's operating costs.

[0028] See Figures 1 to 5As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides an aerosol generating device. The aerosol generating device includes a housing 10, an atomizing part and a control part 20 installed inside the housing 10. The control part 20 includes a frame 21 and a control component 22 installed on the frame 21. The control component 22 is electrically connected to the atomizing part. The control component 22 includes a press trigger part 221. A first spring arm 211 is provided on the frame 21. The position of the first spring arm 211 corresponds to the position of the press trigger part 221. The first spring arm 211 can be bent toward the press trigger part 221 under force so that the first spring arm 211 can trigger the press trigger part 221. A second spring arm 121 is provided on the housing 10. The position of the second spring arm 121 corresponds to the position of the first spring arm 211. The second spring arm 121 can be bent toward the press trigger part 221 under force so that the second spring arm 121 pushes the first spring arm 211 to bend toward the press trigger part 221. The aerosol generator is a device capable of converting an aerosol matrix into inhalable aerosols through specific methods such as heating or ultrasound. The outer casing 10 forms the external housing of the aerosol generator, housing and protecting the internal functional components and providing a gripping interface for the user. The atomizing unit is the core component of the aerosol generator, typically including a reservoir for storing the aerosol matrix and an atomizer for atomizing the matrix. The control unit 20 coordinates and controls the overall workflow of the aerosol generator, including power supply control for the atomizing unit, user operation response, and status monitoring of each functional module.

[0029] It should be noted that the frame 21 is the main support structure of the control unit 20, used to fix and support the control component 22 and other related components. The control component 22 is a functional module integrating electronic components, such as a PCBA assembly, used to control the start and stop of the atomizing unit and its operating parameters. The press trigger part 221 is the part on the control component 22 that receives external mechanical trigger signals; its state change can generate an electrical signal to trigger the corresponding function.

[0030] It should be noted that the first elastic arm 211 is an elastic cantilever structure integrally formed or fixedly connected to the frame 21. Its position corresponds to above or to the side of the press trigger part 221. It can elastically bend when subjected to downward pressing force, thereby displacing itself to contact the press trigger part 221 and triggering it. The second elastic arm 121 is an elastic cantilever structure integrally formed or fixedly connected to the outer shell 10. Its position corresponds vertically to or cooperates with the first elastic arm 211, serving as the direct or indirect pressing operation part for the user. When the user presses the second elastic arm 121, the second elastic arm 121 undergoes elastic deformation and pushes the first elastic arm 211 below, thereby reliably triggering the press trigger part 221 through the bending movement of the first elastic arm 211.

[0031] In this embodiment, the aerosol generator forms a linkage triggering structure through the first spring arm 211 on the frame 21 and the second spring arm 121 on the outer shell 10. When the linkage triggering structure is pressed, the second spring arm 121 can push the first spring arm 211 to elastically bend together to trigger the pressing trigger part 221. The linkage triggering structure eliminates the need for purchasing and assembling independent silicone buffer components, simplifies the assembly process of the aerosol generator, and reduces the production cost of the aerosol generator. Furthermore, the linkage triggering structure can also absorb impact energy through the elastic deformation of the first spring arm 211 and the second spring arm 121, achieving buffering and noise reduction in the triggering process. While avoiding abnormal pressing noise, it provides a soft and sensitive pressing feel, thereby improving the reliability and user experience of the aerosol generator.

[0032] See Figures 2 to 4 As shown, in a specific embodiment, the first spring arm 211 includes a first elastic segment 2111 and a first trigger segment 2112. The first end of the first elastic segment 2111 is connected to the frame 21, and the second end of the first elastic segment 2111 is connected to the first trigger segment 2112. The position of the first trigger segment 2112 corresponds to the position of the press trigger part 221. The first elastic segment 2111 is the part of the first spring arm 211 that provides elastic deformation. Its first end is fixedly connected to the frame 21 for support, and its second end is connected to the first trigger segment 2112. The first trigger segment 2112 achieves displacement and reset through its own bending deformation. The first trigger segment 2112 is the part of the first spring arm 211 that performs the triggering action. Its position precisely corresponds to the press trigger part 221. When subjected to pressing pressure, the first trigger segment 2112 directly or indirectly contacts and activates the press trigger part 221.

[0033] In this embodiment, the aerosol generating device divides the first spring arm 211 into a first elastic segment 2111 and a first trigger segment 2112, which facilitates independent optimization of the elastic performance and triggering performance of the first spring arm 211. Specifically, the first elastic segment 2111 is used to provide restoring elastic force to the first spring arm 211, ensuring that the first spring arm 211 can reliably reset after being pressed. The first trigger segment 2112 is used to contact the pressing trigger part 221, ensuring that the first spring arm 211 can trigger the pressing trigger part 221. By adjusting the structure of the first elastic segment 2111 and the first trigger segment 2112 respectively, first spring arms 211 with different elastic performance and triggering performance can be obtained, thereby meeting the triggering and feel requirements of different types and models of pressing trigger parts 221.

[0034] From the perspective of durability and reliability, the division of the first elastic segment 2111 and the first triggering segment 2112 is beneficial to improving the local stress distribution of the first elastic arm 211, reducing the risk of fatigue fracture caused by local stress concentration in the first elastic arm 211 under long-term use, thereby enhancing the durability and reliability of the first elastic arm 211.

[0035] See Figure 2 and Figure 3 As shown, in a specific embodiment, the press trigger 221 includes a button 2211, and a first trigger segment 2112 abuts against the button 2211. The button 2211 is a microswitch button or other triggerable electronic component. The first trigger segment 2112 abutting against the button 2211 means that the first trigger segment 2112 is in physical contact with the button 2211 in its natural state and applies a certain pre-pressure, thereby establishing a gapless force transmission path between the first spring arm 211 and the button 2211, eliminating any idle travel between the first spring arm 211 and the button 2211, ensuring that the pressing force on the first spring arm 211 can be transmitted to the button 2211 instantly and without loss, thus improving the sensitivity and reliability of the button 2211's triggering.

[0036] In addition, the first trigger segment 2112 is set to directly abut against the button 2211 of the press trigger part 221, so that the aerosol generating device can absorb the impact energy through the elastic deformation of the first spring arm 211 and the trigger stroke of the button 2211, thereby optimizing the buffering effect and softness of the button 2211 during the triggering process, and improving the user's operating experience while ensuring accurate triggering.

[0037] See Figures 1 to 5 As shown, in a specific embodiment, the second spring arm 121 includes a second elastic segment 1211 and a second trigger segment 1212. The first end of the second elastic segment 1211 is connected to the outer shell 10, and the second end of the second elastic segment 1211 is connected to the second trigger segment 1212. The position of the second trigger segment 1212 corresponds to the position of the first trigger segment 2112. The second elastic segment 1211 is the part of the second spring arm 121 that provides elastic deformation. Its first end is fixedly connected to the outer shell 10 for support, and its second end is connected to the second trigger segment 1212. The second trigger segment 1212 achieves displacement and reset through its own bending deformation. The second trigger segment 1212 is the part of the second spring arm 121 that transmits pressing pressure and interacts with the first spring arm 211. Its position precisely corresponds to the first trigger segment 2112. When subjected to pressing pressure, the second trigger segment 1212 directly or indirectly contacts the first trigger segment 2112 and drives the first trigger segment 2112 to activate the pressing trigger part 221.

[0038] In this embodiment, the aerosol generating device divides the second spring arm 121 into a second elastic segment 1211 and a second trigger segment 1212, which facilitates independent optimization of the elastic and triggering performance of the second spring arm 121. Specifically, the second elastic segment 1211 is used to provide restoring elasticity to the second spring arm 121, ensuring that the second spring arm 121 can reliably reset after being pressed. The second trigger segment 1212 is used to contact the first trigger segment 2112, ensuring that the second spring arm 121 can trigger the pressing trigger part 221 by driving the first spring arm 211. By adjusting the structure of the second elastic segment 1211 and the second trigger segment 1212 respectively, second spring arms 121 with different elastic and triggering performance can be obtained, thereby meeting the triggering and tactile requirements of different types and models of first spring arms 211 and pressing trigger parts 221.

[0039] From the perspective of durability and reliability, the division of the second elastic segment 1211 and the second triggering segment 1212 is beneficial to improving the local stress distribution of the second spring arm 121, reducing the risk of fatigue fracture caused by local stress concentration in the second spring arm 121 under long-term use, thereby enhancing the durability and reliability of the second spring arm 121.

[0040] See Figure 2 and Figure 3 As shown, in a specific embodiment, the second trigger segment 1212 abuts against the first trigger segment 2112. The second trigger segment 1212 abutting against the first trigger segment 2112 means that the second trigger segment 1212 is in physical contact with the first trigger segment 2112 in its natural state and applies a certain pre-pressure. This establishes a gapless force transmission path between the second spring arm 121 and the first spring arm 211, eliminating any idle travel between them and ensuring that the pressing pressure on the second spring arm 121 can be transmitted to the first spring arm 211 instantly and without loss. This further improves the sensitivity and reliability of the button 2211.

[0041] Furthermore, by setting the second trigger segment 1212 to directly abut against the first trigger segment 2112 of the first spring arm 211, the aerosol generator can absorb the impact energy through the elastic deformation of the second spring arm 121, the first spring arm 211, and the trigger stroke of the button 2211. This further optimizes the buffering effect and tactile smoothness of the button 2211 during the triggering process, ensuring accurate triggering while improving the user's operating experience.

[0042] In one specific embodiment, the first trigger segment 2112 is provided with a first protrusion, which abuts against the second trigger segment 1212. The first protrusion is a partial raised structure formed on the surface of the first trigger segment 2112 facing the second trigger segment 1212, and its cross-sectional shape can be arc-shaped, polygonal, or other geometric shapes. The first protrusion abutting against the second trigger segment 1212 means that the first protrusion is in physical contact with the second trigger segment 1212 in its natural state and applies a certain pre-pressure. The contact between the first protrusion and the second trigger segment 1212 is one of point contact, line contact, and surface contact.

[0043] From the perspective of triggering resistance, a first protrusion is provided on the first triggering segment 2112, and the first triggering segment 2112 abuts against the second triggering segment 1212 through the first protrusion. This allows the first triggering segment 2112 to adjust the contact area between the two triggering segments by changing the shape of the first protrusion, thereby reducing the frictional resistance when the first triggering segment 2112 and the second triggering segment 1212 slide relative to each other. This makes the transmission of pressing force between the first triggering segment 2112 and the second triggering segment 1212 smoother and more sensitive, and reduces or even avoids triggering delay or jamming caused by friction.

[0044] From the perspective of assembly precision and production consistency, the setting of the first protrusion can reduce the alignment precision requirements of the first trigger segment 2112 and the second trigger segment 1212 during the assembly process, thereby improving production efficiency and yield. Furthermore, the setting of the first protrusion can also enable the first trigger segment 2112 to better adapt to manufacturing tolerances, ensuring that the first trigger segment 2112 can obtain a stable and consistent trigger feel and reliability in different batches of production, thus improving the overall quality of the aerosol generator.

[0045] See Figure 2 , Figure 3 and Figure 5 As shown, in another embodiment, the second trigger segment 1212 in this embodiment is provided with a second protrusion 12121, which abuts against the first trigger segment 2112. The second protrusion 12121 is a partial raised structure formed on the surface of the second trigger segment 1212 facing the first trigger segment 2112, and its cross-sectional shape can be arc-shaped, polygonal, or other geometric shapes. The second protrusion 12121 abutting against the first trigger segment 2112 means that the second protrusion 12121 has physical contact with the first trigger segment 2112 in its natural state and applies a certain pre-pressure. The contact between the second protrusion 12121 and the first trigger segment 2112 is one of point contact, line contact, and surface contact.

[0046] From the perspective of triggering resistance, a second protrusion 12121 is provided on the second triggering segment 1212, and the second triggering segment 1212 abuts against the first triggering segment 2112 through the second protrusion 12121. This allows the second triggering segment 1212 to adjust the contact area between the two triggering segments by changing the shape of the second protrusion 12121, thereby reducing the frictional resistance when the first triggering segment 2112 and the second triggering segment 1212 slide relative to each other. This makes the transmission of pressing force between the first triggering segment 2112 and the second triggering segment 1212 smoother and more sensitive, and reduces or even avoids triggering delay or jamming caused by friction.

[0047] From the perspective of assembly accuracy and production consistency, the setting of the second protrusion 12121 can reduce the alignment accuracy requirements between the second trigger segment 1212 and the first trigger segment 2112 during the assembly process, thereby improving production efficiency and yield. Furthermore, the setting of the second protrusion 12121 can also enable the second trigger segment 1212 to better adapt to manufacturing tolerances, ensuring that the second trigger segment 1212 can obtain a stable and consistent trigger feel and reliability in different batches of production, thus improving the overall quality of the aerosol generator.

[0048] In another embodiment, the first trigger segment 2112 is provided with a third protrusion, and the second trigger segment 1212 is provided with a fourth protrusion, with the third and fourth protrusions abutting against each other. The third protrusion is a partially raised structure formed on the surface of the first trigger segment 2112 facing the second trigger segment 1212, and its cross-sectional shape can be arc-shaped, polygonal, or other geometric shapes. The fourth protrusion is also a partially raised structure formed on the surface of the second trigger segment 1212 facing the first trigger segment 2112, and its cross-sectional shape can be arc-shaped, polygonal, or other geometric shapes. The abutting of the third and fourth protrusions means that the third protrusion is in physical contact with the fourth protrusion in its natural state and a certain pre-pressure is applied. The contact between the third and fourth protrusions is one of point contact, line contact, and surface contact.

[0049] In terms of the diversity of trigger feel, a third protrusion is provided on the first trigger segment 2112 and a fourth protrusion is provided on the second trigger segment 1212. The first trigger segment 2112 and the second trigger segment 1212 are abutted by the third and fourth protrusions. This can further concentrate the contact between the two trigger segments in the local area between the third and fourth protrusions, further reducing the frictional resistance and wear when the first trigger segment 2112 and the second trigger segment 1212 move relative to each other, ensuring the smoothness and sensitivity of the pressing force transmission. By changing the shape of the third and fourth protrusions, the trigger force and feel can be finely adjusted to meet the diverse user experience needs.

[0050] See Figure 5As shown, in a specific embodiment, the second trigger segment 1212 is provided with a second protrusion 12121, which abuts against the first trigger segment 2112. The second trigger segment 1212 includes a pressing portion, and the second protrusion 12121 is disposed on the pressing portion. The pressing portion includes a pressing extension section 12122. The pressing portion is a local area or functional part of the second trigger segment 1212 for direct force application by the user. The second protrusion 12121 is directly formed on the surface of the pressing portion facing the first trigger segment 2112, serving as a contact point for force transmission. The pressing extension section 12122 is an extension structure located at the end of the pressing portion, extending away from the center of the pressing portion to increase the area of ​​the pressing portion on the user's operating side.

[0051] In terms of comfort and reliability, the extended pressing section 12122 increases the contact area between the pressing part and the user's fingers, disperses the pressure on the fingers during pressing, and improves the comfort of operation. In addition, the larger contact area can provide a more stable force application interface, prevent slippage during operation, and improve the accuracy and controllability of pressing.

[0052] In some embodiments, the extension direction of the pressing extension section 12122 in this embodiment is parallel to the width direction of the outer shell portion 10. The width direction of the outer shell portion 10 is a horizontal axis perpendicular to the length direction of the outer shell portion 10. Setting the extension direction of the pressing extension section 12122 to be parallel to the width direction of the outer shell portion 10 extends the lateral dimension of the pressing extension section 12122 on the front side of the aerosol generating device, thereby effectively increasing the lateral contact area with the user's fingers and optimizing the comfort and stability of the user's force application.

[0053] See Figures 1 to 5 As shown, in a specific embodiment, the outer shell 10 includes a shell body 11 and a light-transmitting part. The light-transmitting part includes a light-transmitting body 12, which is mounted on the shell body 11. A second spring arm 121 is disposed on the light-transmitting body 12. The control component 22 also includes a display part 222, and the light emitted by the display part 222 can be displayed outward through the light-transmitting body 12. The light-transmitting part is a component on the outer shell 10 that serves both structural support and optical functions. The light-transmitting body 12 is the main component of the light-transmitting part, made of a material that allows light to pass through, such as transparent or translucent plastic or glass. It is fixedly installed on the outer shell 11 and together with the outer shell 11, it forms a complete outer shell. The display part 222 is a unit in the control component 22 used to generate visual information, such as an LED indicator screen or an OLED display screen. The light emitted by it can be observed by the user after passing through the light-transmitting body 12. The second spring arm 121 being set on the light-transmitting body 12 means that the second spring arm 121 and the light-transmitting body 12 are integrally formed or fixedly connected to the surface of the light-transmitting body 12, thereby realizing the functional integration of the second spring arm 121 and the light-transmitting body 12 on the light-transmitting part.

[0054] From the perspective of structural simplification and production feasibility, integrating the second spring arm 121 into the light-transmitting body 12 of the light-transmitting part can simplify the structural complexity and opening design of the shell body 11, and reduce the difficulty and cost of mold manufacturing of the shell body 11.

[0055] From the perspective of production efficiency and quality control, integrating the second spring arm 121 into the light-transmitting body 12 of the light-transmitting part can make the second spring arm 121 and the light-transmitting body 12 form an independent module, which facilitates the pre-assembly and functional testing of the second spring arm 121 and the light-transmitting body 12, thereby realizing modular production, effectively improving the production and assembly efficiency and product yield of the aerosol generator, and reducing the failure rate in the final assembly stage.

[0056] In some embodiments, the light-transmitting body 12 in this embodiment is fixedly mounted on the shell body 11 by adhesive bonding. Of course, in other embodiments, the light-transmitting body 12 in this embodiment can also be mounted on the shell body 11 by other means such as threaded fastener connection.

[0057] In some embodiments, the shell body 11 in this embodiment includes an outer shell and a bottom cover. The outer shell is provided with a receiving recess, and the bottom cover is provided on the receiving recess and together with the receiving recess, forms a receiving cavity in the shell body 11. The atomizing part and the control part 20 are both provided in the receiving cavity.

[0058] In some embodiments, the shell body 11 in this embodiment is provided with a display opening communicating with the receiving cavity, and the light-transmitting body 12 covers the display opening. The light emitted by the display unit 222 enters the light-transmitting body 12 through the display opening and is displayed outward through the light-transmitting body 12.

[0059] In some embodiments, the shell body 11 in this embodiment is provided with a clearance opening communicating with the receiving cavity, and at least part of the second spring arm 121 can pass through the clearance opening and abut against the first spring arm 211.

[0060] In one specific embodiment, the outer surface of the second trigger segment 1212 is provided with a concave-convex structure. The concave-convex structure refers to the regular or irregular continuous texture features formed on the outer surface of the second trigger segment 1212, that is, on the operating surface that directly contacts the user's finger.

[0061] From the perspective of operational reliability and human-computer interaction experience, the concave-convex structure, through alternating or non-uniformly distributed protrusions and depressions, macroscopically increases the actual friction coefficient of the outer surface of the second trigger segment 1212, thereby enhancing the tactile feedback and anti-slip performance of the outer surface of the second trigger segment 1212, ensuring the accuracy and stability of force application during operation, preventing slippage or accidental touch. In addition, the concave-convex structure can also provide users with unique tactile recognition, enhance the intuitiveness and confirmation during operation, and improve the accuracy and satisfaction of interaction.

[0062] See Figure 4 As shown, in a specific embodiment, both the first spring arm 211 and the second spring arm 121 extend along the length direction of the outer casing 10. The length direction of the outer casing 10 refers to the axial direction with the longest dimension in the overall shape of the aerosol generator.

[0063] From the perspective of space utilization and structural layout, setting the first spring arm 211 and the second spring arm 121 to extend along the length direction of the outer shell 10 can make full use of the longitudinal space inside the aerosol generator, which is conducive to achieving a compact and miniaturized design of the aerosol generator structure.

[0064] From the perspective of structural stability and service life, setting the first spring arm 211 and the second spring arm 121 to extend along the length direction of the outer shell 10 can make the movement direction of the fixed end and the free end of the first spring arm 211 and the second spring arm 121 clear, reduce the risk of unexpected deformation of the first spring arm 211 and the second spring arm 121, and help improve the stability of the internal structure of the aerosol generator and the durability of long-term use.

[0065] In summary, the aerosol generator provided in this embodiment has at least the following beneficial technical effects: The aerosol generator provided in this embodiment forms a linkage triggering structure through the first spring arm 211 provided on the frame 21 and the second spring arm 121 provided on the outer shell 10. When the linkage triggering structure is pressed, the second spring arm 121 can push the first spring arm 211 to undergo elastic bending together to trigger the pressing trigger part 221. The linkage triggering structure allows the aerosol generator to eliminate the procurement and assembly of independent silicone buffer parts, simplifying the assembly process of the aerosol generator and reducing the production cost of the aerosol generator. Furthermore, the linkage triggering structure can also absorb impact energy through the elastic deformation of the first spring arm 211 and the second spring arm 121, realizing buffering and noise reduction in the triggering process. While avoiding abnormal pressing noise, it provides a soft and sensitive pressing feel, thereby improving the reliability and user experience of the aerosol generator.

[0066] 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.
