Description

Technical Field

[0001] This application relates to the field of heated non-combustible atomization technology, and more particularly to an aerosol generating device. Background Technology

[0002] The working principle of the heated non-combustible aerosol generator is to control the heating element to heat the aerosol generating matrix, ensuring that the aerosol generating matrix releases aerosols without direct combustion, which can reduce the generation of harmful substances.

[0003] In related technologies, heated non-combustible aerosol generating devices typically include a main body and a shielding component. The main body has an insertion port for inserting the aerosol generating matrix. The shielding component is usually driven by a drive unit and moves relative to the main body to open and close the insertion port, protecting it from dust or foreign matter when the aerosol generating device is not in use. The shielding component maintains a stable position in the open or closed position through friction with the main body.

[0004] However, frequent opening and closing operations can cause wear on the contact surface between the shield and the main body, reducing friction and affecting the positional stability of the shield. Utility Model Content

The driving assembly is configured to move relative to the main body to drive the blocking member to move relative to the main body, thereby closing or opening the first insertion port. When the blocking member is in the closed or open state of the first insertion port, the positioning part can connect with the limiting member to maintain the relative position of the driving assembly and the main body. By providing a limiting member on the main body, which cooperates with the positioning part of the driving assembly, the position of the driving assembly can be limited, ensuring that the blocking member can be stably maintained in a predetermined position when the first insertion port is closed or opened. This avoids positional displacement of the blocking member due to external force or wear, improving the stability and reliability of the blocking member, and enabling the aerosol generating device to maintain the stability and reliability of the blocking member during frequent opening and closing.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0089] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments.

For those skilled in the art, the specific meaning of these terms in the embodiments of this application can be understood according to the specific circumstances.

[0091] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0092] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the present application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0093] In this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0094] As can be seen from the background technology, the working principle of the aerosol generating device is to control the heating element to heat the aerosol generating matrix, so as to ensure that the aerosol generating matrix releases aerosols in a state of non-direct combustion, which can reduce the generation of harmful substances.

[0095] In related technologies, the aerosol generating matrix typically includes a main body and a shielding component. The main body has a first insertion port for inserting the aerosol generating matrix. The shielding component is typically driven by a drive component and moves relative to the main body to open and close the first insertion port, thus protecting the first insertion port from contamination by dust or foreign matter when the aerosol generating device is not in use.

[0096] For example, the utility model patent with publication number CN217184814U proposes an aerosol generating device, including a main body and blades. The blades are rotatably connected to the main body. Driven by the rotating structural component, the blades move from a first position to a second position, which can cover at least a portion of the upper opening of the receiving cavity.

[0097] At the same time, the contact between the blade and the connector generates friction, which acts as a self-locking force, allowing the blade to remain stably at any position between the starting point and the ending point.

[0098] However, in the above scheme, frequent opening and closing operations will cause wear on the contact surface between the shield and the main body, reduce friction, and affect the positional stability of the shield.

[0099] Furthermore, the blades have a limited coverage area over the opening at the top of the cavity, only achieving partial coverage and making it difficult to form a complete seal, thus affecting the dustproof performance to some extent.

[0100] In view of this, this application provides an aerosol generating device, including a main body, a driving assembly, and a blocking member; the main body is provided with a first insertion port and a limiting member; the driving assembly is movably connected to the main body and connected to the blocking member, and the driving assembly is provided with a positioning part; the driving assembly is configured to move relative to the main body to drive the blocking member to move relative to the main body, and the blocking member closes or opens the first insertion port; when the blocking member is in the closed or open state of the first insertion port, the positioning part can connect with the limiting member to maintain the relative position of the driving assembly and the main body. By providing a limiting member on the main body, which cooperates with the positioning part provided on the driving assembly, the position of the driving assembly can be limited, ensuring that the blocking member can be stably maintained in a predetermined position when the first insertion port is closed or opened, thereby avoiding positional displacement of the blocking member due to external force or wear, improving the stability and reliability of the blocking member, and enabling the aerosol generating device to maintain the stability and reliability of the blocking member during frequent opening and closing.

[0101] Driven by the drive component, the shielding member can completely cover the first insertion port. Combined with the cooperation of the limiting member and the positioning part, the shielding member can remain stable in the position of closing the first insertion port, thus achieving effective sealing of the first insertion port and facilitating effective dust prevention when the aerosol generating device is not used.

[0102] The technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0103] Combination Figure 1 and Figure 9As shown, this application provides an aerosol generating device, including a main body 100, the main body 100 being provided with a first insertion port 101.

[0104] Understandably, the main body 100 typically has an installation cavity, which contains a heating element, such as a heating needle or a heating plate. The first insertion port 101 communicates with the installation cavity and is used to insert an insert (such as an aerosol generating matrix) into the installation cavity, so that the aerosol generating matrix comes into contact with the heating element, thereby heating it.

[0105] During the heating process, the heating element generates heat, heating the aerosol generating matrix to a suitable temperature (e.g., between 300-350°C), causing the chemical components in the aerosol generating matrix to undergo a pyrolysis reaction and release aerosols.

[0106] Combination Figure 2 As shown, in some embodiments, the body 100 includes a first portion and a second portion connected together.

[0107] The first part is located on top of the second part. The first part can be connected to the second part through at least one of the following: a snap-fit ​​structure, a plug-in structure, or a locking structure, as long as a stable connection can be achieved. This application embodiment does not impose any restrictions on this.

[0108] The first part and the second part can be configured to form a mounting cavity for accommodating the heating element; the first insertion port 101 is opened on the side of the first part opposite to the second part.

[0109] The user can insert the aerosol generating matrix into the mounting cavity through the first insertion port 101 to contact the heating element, and the heating element heats the aerosol generating matrix.

[0110] In some embodiments, the body 100 further includes a sealing ring 140 disposed between the first portion and the second portion.

[0111] Understandably, placing the sealing ring 140 between the first and second parts helps ensure a tight seal at the connection between the two parts, preventing air, aerosols, or liquids from leaking out. This arrangement helps maintain the stability of the internal environment, ensuring the effective operation of the heating element.

[0112] For example, the sealing ring 140 is typically made of an elastic material, such as silicone or rubber, to provide good sealing performance.

[0113] In some embodiments, the aerosol generating apparatus further includes a driving component 200 and a blocking component 300. The driving component 200 is movably connected to the main body 100 and connected to the blocking component 300. The driving component 200 is configured to move relative to the main body 100 to drive the blocking component 300 to move relative to the main body 100. The blocking component 300 closes or opens the first insertion port 101.

[0114] When an appropriate force is applied to the drive assembly 200, the drive assembly 200 can move relative to the main body 100, and the drive assembly 200 can also directly transmit the motion to the blocking member 300, so that the blocking member 300 also moves relative to the main body 100, thereby realizing the effective opening and closing of the first insertion port 101.

[0115] Specifically, the drive component 200 and the shielding component 300 are located on the first part, which simplifies the structural layout and makes operation and control more centralized and convenient.

[0116] Combination Figure 2 and Figure 10 As shown, in some embodiments, the aerosol generating device further includes an upper bracket 400, which is connected to the main body 100. The upper bracket 400 is disposed on the side of the main body 100 facing the shield 300. The upper bracket 400 is provided with a second insertion port 401, which corresponds to and communicates with the first insertion port 101.

[0117] The upper bracket 400 is located on the side of the main body 100 facing the shield 300. The upper bracket 400 can cover the outside of the drive assembly 200 and the shield 300. On the one hand, it can provide a limit for the drive assembly 200 and the shield 300, restricting their movement along the height direction of the main body 100 (i.e., the arrangement direction of the first part and the second part); on the other hand, it can protect the drive assembly 200 and the shield 300, preventing the external environment from affecting their normal operation.

[0118] The second insertion port 401 corresponds to and is connected to the first insertion port 101, which can ensure that the inserted object can smoothly pass through the upper bracket 400 and enter the body 100.

[0119] For example, the upper bracket 400 can be connected to the first part of the main body 100 through at least one of a snap-fit ​​structure, a plug-in structure or a locking structure, as long as a stable connection can be achieved. This application embodiment does not impose any restrictions on this.

[0120] In some embodiments, the aerosol generating device further includes a top cover 500, which is connected to the main body 100. The top cover 500 covers the side of the main body 100 facing the upper bracket 400. The top cover 500 is provided with a third insertion port 501, which corresponds to and communicates with the first insertion port 101 via the second insertion port 401.

[0121] Understandably, the top cover 500 is positioned on top of the aerosol generating device for direct contact with the user's hands. The top cover 500 provides additional protection for the upper bracket 400 and enhances aesthetics, thereby improving the user experience.

[0122] The third insertion port 501 provides an additional channel, allowing the user to perform insertion operations through the top cover 500 without completely removing the top cover 500.

[0123] For example, the top cover 500 can be connected to the first part of the main body 100 through at least one of a snap-fit ​​structure, a plug-in structure or a locking structure, as long as a stable connection can be achieved. This application embodiment does not impose any restrictions on this.

[0124] In some embodiments, the upper bracket 400 is provided with a decorative ring 410, which is connected to the side of the upper bracket 400 away from the main body 100 and is disposed on the outer periphery of the second insertion port 401.

[0125] Understandably, the insert needs to enter the first insert port 101 sequentially through the third insert port 501 and the second insert port 401. Therefore, it is necessary to ensure the alignment and sealing of the third insert port 501 and the second insert port 401.

[0126] The decorative ring 410 is located between the upper bracket 400 and the top cover 500, providing a decorative effect while also connecting the second insertion port 401 and the third insertion port 501. In addition, the decorative ring 410 also protects the edge of the second insertion port 401 from wear and damage.

[0127] Combination Figure 2 and Figure 10 As shown, in some embodiments, the main body 100 is provided with a limiting member 111, and the drive assembly 200 is provided with a positioning part; when the blocking member 300 is in the state of closing and opening the first insertion port 101, the positioning part can be connected with the limiting member 111 to maintain the relative position of the drive assembly 200 and the main body 100.

[0128] It should be noted that when the aerosol generating device is not in operation, the shielding member 300 needs to keep the first insertion port 101 closed in order to protect the first insertion port 101.

[0129] When the aerosol generating device is in operation, the heating element is running. Since it is necessary to insert an insert into the first insertion port 101, the shield 300 needs to keep the first insertion port 101 open.

[0130] When the shielding member 300 closes and opens the first insertion port 101, the positioning part can connect with the limiting member 111, which can ensure that the shielding member 300 can be stably maintained in the predetermined position when closing or opening the first insertion port 101, thereby improving the stability and reliability of the shielding member 300.

[0131] Understandably, the limiter 111 provides a physical constraint so that the drive assembly 200 can stop precisely at a predetermined position when moving, preventing positional deviation due to external force or wear.

[0132] The positioning part cooperates with the limiting member 111 to provide additional stability and prevent the drive assembly 200 from moving unexpectedly during operation.

[0133] For example, the limiting member 111 can be configured as a structure that fits tightly with the positioning part, such as a groove or a protrusion. Through this fit, the limiting member 111 can provide a clear stop signal when the drive assembly 200 reaches a specific position, thereby improving the accuracy and reliability of operation.

[0134] The positioning part is typically designed as a structure that matches the limiting member 111, such as a snap or a groove. With this design, the positioning part can be tightly engaged with the limiting member 111 when the drive assembly 200 reaches a specific position, thereby providing additional fixing force.

[0135] Specifically, the aerosol generating device provided in this application embodiment, by setting a limiting member 111 on the main body 100, which cooperates with the positioning part set on the drive component 200, can limit the position of the drive component 200, ensuring that the shielding member 300 can be stably maintained in a predetermined position when the first insertion port 101 is closed or opened, thereby avoiding the positional displacement of the shielding member 300 due to external force or wear, improving the stability and reliability of the shielding member 300, and enabling the aerosol generating device to maintain the stability and reliability of the shielding member 300 during frequent opening and closing.

[0136] Driven by the drive component 200, the shield 300 can completely cover the first insertion port 101. Combined with the cooperation of the limiting component 111 and the positioning part, the shield 300 can remain stable in the position of closing the first insertion port 101, thus achieving effective sealing of the first insertion port 101 and facilitating effective dust prevention when the aerosol generating device is not used.

[0137] Combination Figure 2 , Figure 5 and Figure 10As shown, in some embodiments, the main body 100 is provided with a rotating shaft 110, and the driving component 200 is sleeved on the rotating shaft 110. The driving component 200 is rotatably connected to the rotating shaft 110 to drive the blocking member 300 to move relative to the main body 100.

[0138] The first insertion port 101 and the rotating shaft 110 are spaced apart along the length of the main body 100. The driving component 200 is sleeved on the rotating shaft 110. When the driving component 200 is rotatably connected to the rotating shaft 110, it can drive the blocking member 300 to move along the length of the main body 100 to move closer to or away from the first insertion port 101, thereby closing or opening the first insertion port 101.

[0139] In some embodiments, a limiting member 111 is disposed on a rotating shaft 110, and at least a portion of the limiting member 111 protrudes from the outer peripheral surface of the rotating shaft 110; a positioning portion is disposed on the side of the drive assembly 200 facing the rotating shaft 110.

[0140] Understandably, the positioning arrangement of the limit member 111 and the positioning part ensures that the drive assembly 200 can accurately reach and remain in the predetermined position during rotation.

[0141] The limiting member 111 is positioned on the rotating shaft 110, and it can effectively contact the positioning part when the drive assembly 200 rotates. This arrangement reduces additional components and complex structures, while providing a stable limiting function by utilizing the central position of the rotating shaft 110.

[0142] The protruding portion of the limiting member 111 can contact the positioning part when the drive assembly 200 rotates to a specific position. This physical contact provides a clear stop signal, realizes a precise limiting function, and prevents the drive assembly 200 from over-rotating or failing to reach the predetermined position.

[0143] The positioning part is located on the side of the drive assembly 200 facing the rotating shaft 110, which can ensure effective contact with the limiting member 111 during rotation.

[0144] In some embodiments, there are two limiting members 111, which are symmetrically arranged on the rotating shaft 110. There are two sets of positioning parts, each corresponding to a limiting member 111. By providing two limiting members 111, the number of connection points is increased, which helps to improve the connection effect between the positioning part and the limiting member 111. When the blocking member 300 closes and opens the first insertion port 101, the relative position of the driving assembly 200 and the main body 100 becomes more stable.

[0145] Combination Figure 2 , Figure 3 and Figure 10As shown, in some embodiments, there are multiple positioning parts in each group, including a first positioning part 2111 and a second positioning part 2112; when the blocking member 300 closes the first insertion port 101, the limiting member 111 is connected to the first positioning part 2111; when the blocking member 300 opens the first insertion port 101, the limiting member 111 is connected to the second positioning part 2112.

[0146] Understandably, by providing multiple positioning parts on the drive assembly 200, specific limiting positions can be provided for different operating states (such as the blocking member 300 closing and opening the first insertion port 101). The first positioning part 2111 and the second positioning part 2112 correspond to different states of the blocking member 300, respectively, ensuring positioning accuracy in each state.

[0147] Combination Figure 3 As shown, in some embodiments, a plurality of positioning portions are arranged sequentially and at intervals around the circumference of the rotating shaft 110 on the inner wall of the drive assembly 200.

[0148] By arranging multiple positioning parts circumferentially at intervals on the inner wall of the drive assembly 200, clear limiting positions can be provided for different operating states. The position and interval of each positioning part can be flexibly set to ensure that it can mate with the limiting member 111 when the drive assembly 200 rotates to the corresponding position. This arrangement not only improves the positioning accuracy but also simplifies the structural design, enabling the device to achieve stable positioning in multiple states within a limited space.

[0149] Specifically, in the horizontal plane, there is an angle between the line connecting two adjacent positioning parts and the axis of the rotating shaft 110, and the angle can be from 30° to 60°, preferably 40°.

[0150] The first positioning part 2111 and the second positioning part 2112 are two positioning parts in adjacent positions. The angle between the line connecting the two parts and the axis of the rotating shaft 110 is set to 40°. When the user rotates the drive assembly 200 to move the shield 300 from the state of closing the first insertion port 101 to the state of opening the first insertion port 101, the user only needs to rotate the drive assembly 200 by 40°. This allows the user to easily switch the state of the shield 300 with one hand, improving the ease of use and operating experience.

[0151] In some embodiments, the first end of the limiting member 111 is connected to the rotating shaft 110, and the second end of the limiting member 111 can extend or retract in a direction close to or away from the rotating shaft 110; the positioning part is a groove; when the limiting member 111 is not connected to the positioning part, the second end of the limiting member 111 is close to the rotating shaft 110, and the second end of the limiting member 111 abuts against the inner wall of the drive assembly 200; when the limiting member 111 is connected to the positioning part, the second end of the limiting member 111 is away from the rotating shaft 110, and the second end of the limiting member 111 is inserted into the groove.

[0152] Understandably, the telescopic performance of the limiting member 111 allows the second end of the limiting member 111 to move in a direction close to or away from the rotating shaft 110 under different operating conditions, so as to effectively connect with the positioning part.

[0153] For example, in the initial state of the aerosol generating device, the shielding member 300 closes the first insertion port 101, and at this time the limiting member 111 and the first positioning part 2111 are in a connected state.

[0154] During the process of manually rotating the drive assembly 200 to move the blocking member 300 from the position of closing the first insertion port 101 to opening the first insertion port 101, the limiting member 111 needs to be disconnected from the first positioning part 2111. During this process, the second end of the limiting member 111 retracts near the rotating shaft 110 and abuts against the inner wall of the drive assembly 200.

[0155] As the drive assembly 200 rotates, when the second positioning part 2112 reaches the position corresponding to the limiting member 111, the second end of the limiting member 111 extends away from the rotating shaft 110 and can be inserted into the second positioning part 2112. At this time, the blocking member 300 is in the state of opening the first insertion port 101.

[0156] By connecting the limiting member 111 with the second positioning part 2112, the position of the driving component 200 can be restricted, and the driving component 200 will not easily move relative to the main body 100, thereby keeping the blocking member 300 in the state of opening the first insertion port 101.

[0157] In some embodiments, the limiting member 111 includes an elastic portion and a fixing portion connected together. The elastic portion is connected to the rotating shaft 110, and at least a portion of the fixing portion protrudes from the outer peripheral surface of the rotating shaft 110. The fixing portion can be connected to the positioning portion.

[0158] Specifically, the fixing part is located at the second end of the limiting member 111. The fixing part can retract near the rotating shaft 110 to compress the elastic part, thereby reducing the length of the elastic part. When the position of the fixing part corresponds to the position of the positioning part, the elastic part extends and can push the fixing part away from the rotating shaft 110 to partially protrude from the outer peripheral surface of the rotating shaft 110 and be inserted into the positioning part.

[0159] For example, the limiting element 111 can be a ball screw or a spring plunger.

[0160] In some embodiments, a sensor is provided on the main body 100 for obtaining the position of the drive component 200.

[0161] The sensor's contact point can be located inside the positioning part, so that the sensor can detect whether the limiting member 111 is connected inside the positioning part, thereby obtaining the position of the drive component 200.

[0162] Specifically, when the shielding member 300 is blocking the first insertion port 101, the limiting member 111 is connected to the first positioning part 2111. The contact point inside the first positioning part 2111 can detect that the limiting member 111 corresponds to the position of the first positioning part 2111 and send a signal to the electronic control system of the main body 100. The electronic control system can control the heating element to stop heating.

[0163] When the user needs to insert an insert for heating, the drive assembly 200 is rotated so that the shield 300 opens the first insertion port 101. When the second positioning part 2112 rotates with the drive assembly 200 and reaches the position corresponding to the limiting member 111, the limiting member 111 connects with the second positioning part 2112. Then, the contact point located inside the second positioning part 2112 can detect the position correspondence between the limiting member 111 and the second positioning part 2112 and send a signal to the electronic control system of the main body 100. The electronic control system can control the heating element to heat.

[0164] With this configuration, the aerosol generating device provided in this application embodiment can obtain the state of the blocking member 300 through the positional correspondence between each positioning part and the limiting member 111, thereby automatically triggering the heating function of the heating element.

[0165] Each group of positioning parts may also include a third positioning part 2113. The first positioning part 2111, the second positioning part 2112 and the third positioning part 2113 are arranged in sequence and spaced apart around the circumference of the rotating shaft 110 on the inner wall of the drive assembly 200.

[0166] When the user needs to adjust the heating intensity, the drive assembly 200 can be rotated while the first insertion port 101 is open in the shield 300, so that the third positioning part 2113 reaches the position corresponding to the limiting part 111. When the limiting part 111 is connected to the third positioning part 2113, the contact point inside the third positioning part 2113 can detect the position correspondence between the limiting part 111 and the third positioning part 2113, and send a signal to the electronic control system of the main body 100. The electronic control system can control the heating element to increase the baking intensity.

[0167] The reverse rotation drive assembly 200 causes the blocking member 300 to close the first insertion port 101. The contacts inside the first positioning part 2111 can detect that the position of the limiting member 111 corresponds to the position of the first positioning part 2111, and send a signal to the electronic control system of the main body 100, which can stop the heating element from heating.

[0168] As can be seen, the aerosol generating device provided in this application embodiment can achieve repeated switching of states through precise rotational motion, thereby improving ease of use and user experience.

[0169] Combination Figure 5 As shown in the figure, in some embodiments, the main body 100 is provided with a guide portion 120; when the blocking member 300 moves relative to the main body 100 to close or open the first insertion port 101, at least one side of the blocking member 300 along the moving direction slides into contact with the guide portion 120.

[0170] Understandably, the guide section 120 effectively restricts the movement path of the blocking member 300, which can ensure that the trajectory of the blocking member 300 is unique and the movement is smooth.

[0171] For example, the guide portion 120 may be in the form of a guide rail, a channel, or a protrusion, as long as it can withstand the moving load of the shield 300 and provide sufficient support. This application embodiment does not impose any restrictions on this.

[0172] In some embodiments, a limiting part 130 is provided at one end of the guide part 120, and the limiting part 130 is located on the periphery of the first insertion port 101; when the blocking member 300 closes the first insertion port 101, the end of the blocking member 300 near the first insertion port 101 abuts against the limiting part 130.

[0173] The limiting part 130 provides a clear physical stop point for the blocking member 300, ensuring that the blocking member 300 can be accurately positioned when it moves to the closed position, which helps to prevent the blocking member 300 from moving excessively.

[0174] The shape of the limiting part 130 is adapted to the shape of the end of the shield 300 near the first insertion port 101 so that the shield 300 and the limiting part 130 can be accurately aligned, so that the shield 300 can completely block the first insertion port 101 in the closed state.

[0175] For example, the guide portion 120 is provided on both sides of the blocking member 300 along the moving direction. The guide portion 120 and the limiting portion 130 are an integral protruding structure. The guide portion 120 and the limiting portion 130 can be configured to form a channel for the blocking member 300 to move, so as to position and guide the blocking member 300.

[0176] Combination Figure 2 and Figure 10As shown, in some embodiments, the drive assembly 200 includes a rotating member 210 and a connecting member 230 connected to each other. The rotating member 210 is rotatably disposed on the main body 100, and the connecting member 230 is connected to the blocking member 300. The rotating member 210 drives the blocking member 300 to move relative to the main body 100 through the connecting member 230.

[0177] Specifically, a mounting hole 211 is provided at the center of the rotating component 210. The rotating component 210 is sleeved on the rotating shaft 110 through the mounting hole 211 and is rotatably connected to the rotating shaft 110. Each positioning part is provided on the inner wall of the mounting hole 211 and is distributed circumferentially along the mounting hole 211.

[0178] Understandably, the rotating member 210 is rotatably mounted on the main body 100. When the driving member rotates relative to the main body 100, it will generate rotational torque. The blocking member 300 needs to move linearly along the length of the main body 100 to get closer to or away from the first insertion port 101, thereby closing or opening the first insertion port 101.

[0179] By setting the connector 230, the rotational torque generated during the rotation of the driving component can be converted into the driving force for the linear movement of the blocking component 300, thus realizing the effective conversion and transmission of motion, thereby enabling the blocking component 300 to move relative to the main body 100 and ensuring that the blocking component 300 can accurately perform opening and closing operations.

[0180] In the longitudinal direction of the main body 100, a notch is provided at the position corresponding to the rotating member 210 on the top cover 500. The notch can expose part of the rotating member 210 to the outside of the top cover 500 so that the user can rotate the rotating member 210.

[0181] Combination Figure 2 and Figure 10 As shown, in some embodiments, the drive assembly 200 includes a toggle member 220, which is sleeved on the outside of the rotating member 210 and is coaxially connected to the rotating member 210.

[0182] As part of the drive assembly 200, the toggle 220 provides a user-operable interface for controlling the functions of the aerosol generating device, allowing the user to control the device through simple manual operation.

[0183] The actuating element 220 and the rotating element 210 are coaxially connected, ensuring that the rotational motion of the actuating element 220 can be directly transmitted to the rotating element 210, achieving efficient motion transmission and reducing energy loss and mechanical complexity.

[0184] For example, the actuating member 220 can be connected to the rotating member 210 through at least one of a snap-fit ​​structure, a plug-in structure or a locking structure, as long as a stable connection can be achieved. This application embodiment does not impose any restrictions on this.

[0185] Specifically, the outer periphery of the toggle element 220 is provided with anti-slip texture 221.

[0186] The anti-slip texture 221 increases the friction of the lever 220, allowing the user to grip the lever 220 more firmly during operation, thereby reducing the possibility of slippage and improving the user's comfort and safety, especially when fingers are wet or oily.

[0187] For example, the anti-slip texture 221 can be achieved by adding an uneven texture to the outer surface of the toggle member 220. These textures can be linear, grid-like, or other geometric shapes, and this application embodiment does not impose any limitations on them.

[0188] Combination Figures 6 to 8 As shown, in some embodiments, the connector 230 is a guide post disposed at the top of the rotating member 210, and the axis of the guide post is offset from the axis of the rotating member 210; the end of the shielding member 300 away from the first insertion port 101 is provided with a groove 301, and the guide post is slidably connected in the groove 301.

[0189] When the guide post moves, it can contact the inner wall of the slide groove 301 near the outer side of the main body 100, generating a driving force to convert the rotational motion of the rotating member 210 into the linear motion of the blocking member 300, so as to effectively drive the sliding of the blocking member 300, thereby realizing the opening and closing operation of the first insertion port 101.

[0190] Combination Figure 6 As shown, when the aerosol generating device is in its initial state, the shielding member 300 closes the first insertion port 101, and the guide post is located at the first end of the extension direction of the slide groove 301.

[0191] Rotating member 210 along the first direction ( Figure 6 When rotated (in the direction indicated by arrow A), the guide post slides along the first end of the slide groove 301 to the second end of the slide groove 301. The guide post drives the shield 300 to move away from the first insertion port 101, which can open the first insertion port 101.

[0192] Combination Figure 7 As shown, when the rotating member 210 is rotated along the first direction to drive the blocking member 300 to open the first insertion port 101, the limiting member 111 can be connected to the second positioning part 2112. At this time, the guide post moves to the second end of the extension direction of the slide groove 301.

[0193] Specifically, when the guide post moves with the rotating part 210, it generates a driving force on the inner wall of the slide groove 301, thereby overcoming the static friction of the blocking part 300 and achieving a smooth opening and closing action.

[0194] Combination Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, the slide 301 is an arc-shaped groove that can be adapted to the movement trajectory of the guide post, ensuring that the guide post can effectively contact the slide 301 during movement, so as to achieve the driving effect on the blocking member 300.

[0195] Combination Figure 8 As shown, when it is necessary to increase the baking intensity, the rotating part 210 can continue to rotate along the first direction so that the limiting part 111 is connected to the third positioning part 2113. During this process, the guide post can move from the second end to the first end in the slide groove 301 along the extension direction of the slide groove 301.

[0196] The guide post is set at the top of the rotating part 210 and its axis is offset from the axis of the rotating part 210. When the rotating part 210 rotates, the guide post will move along a circular path.

[0197] The slide 301 can be configured to match the movement path of the guide post to ensure that the guide post can move smoothly within the slide 301.

[0198] When the shielding member 300 opens the first insertion port 101, the center of the arc groove coincides with the axis of the rotating member 210. The guide post can move within the slide groove 301 without generating a driving force on the inner wall of the slide groove 301. In this state, the position of the shielding member 300 remains unchanged. Rotating the rotating member 210 can only connect the limiting member 111 with the third positioning part 2113, thereby only changing the heating mode.

[0199] With this configuration, as the rotating component 210 rotates, the limiting component 111 will undergo elastic deformation on the inner wall of the mounting hole 211 and at each positioning part, which can optimize the rotation feel and realize the gear switching function.

[0200] Combination Figures 10 to 13 As shown, in some other embodiments, the connector 230 includes a first transmission member 231 and a second transmission member 232; the first transmission member 231 is coaxially connected to the rotating member 210, and the second transmission member 232 meshes with the first transmission member 231; the blocking member 300 is provided with a rack 310, and the second transmission member 232 meshes with the rack 310, the extending direction of the rack 310 is consistent with the distribution direction of the rotating member 210 and the first insertion port 101 on the main body 100; when the driving assembly 200 rotates relative to the main body 100, the first transmission member 231 drives the blocking member 300 to move relative to the main body 100 through the second transmission member 232.

[0201] Specifically, the combination of the first transmission member 231 and the second transmission member 232 can realize the conversion from the rotational motion of the rotating member 210 to the linear motion of the blocking member 300.

[0202] By coaxially connecting the first transmission member 231 and the rotating member 210, the first transmission member 231 can directly receive the rotational motion of the rotating member 210, making motion transmission more direct and efficient. The second transmission member 232 meshes with the first transmission member 231, allowing the motion of the first transmission member 231 to be effectively transmitted to the second transmission member 232, realizing motion conversion or direction change. The rack 310 of the blocking member 300 meshes with the second transmission member 232, enabling the rotational motion of the second transmission member 232 to be converted into the linear motion of the blocking member 300, realizing the opening and closing operation of the blocking member 300.

[0203] The rack 310 extends in the same direction as the shaft 110 and the first insertion port 101, ensuring that the direction of movement of the rack 310 matches the overall structure of the device.

[0204] In some embodiments, the second transmission member 232 includes a gear shaft 2321, and a first gear 2322 and a second gear 2323 coaxially connected to the gear shaft 2321; the first gear 2322 meshes with the first transmission member 231, and the second gear 2323 meshes with the rack 310.

[0205] In practice, when the rotating component 210 is manually rotated, it will drive the first transmission component 231 to rotate. Since the first gear 2322 meshes with the first transmission component 231, the first transmission component 231 will transmit the motion to the first gear 2322 and the second gear 2323. Under the meshing action of the second gear 2323 and the rack 310, the rotation of the second gear 2323 can drive the rack 310 to move linearly, thereby driving the entire blocking component 300 to move closer to or away from the first insertion port 101.

[0206] With this configuration, the aerosol generating device can achieve multi-stage transmission from rotational motion to linear motion, ensuring that the shielding member 300 remains stable and efficient during the opening and closing operation of the first insertion port 101.

[0207] In some embodiments, the rotating member 210 is provided with a limiting groove 212, the main body 100 is provided with a limiting hole 102 communicating with the limiting groove 212, and the gear shaft 2321 is inserted into the limiting hole 102 through the limiting groove 212.

[0208] Specifically, the gear shaft 2321 is inserted into the limiting hole 102 via the limiting groove 212, the second transmission member 232 can be rotatably connected to the main body 100, and the rotating member 210 can be driven by the first transmission member 231 to rotate relative to the main body 100.

[0209] Combination Figure 11 As shown, in some embodiments, when the shield 300 closes the first insertion port 101, the gear shaft 2321 is located at the first end of the extension direction of the limiting groove 212.

[0210] Rotating member 210 along the first direction ( Figure 11 When rotating (in the direction indicated by arrow A), the limiting groove 212 moves with the rotating member 210, and the gear shaft 2321 moves closer to the second end extending in the direction of the limiting groove 212. The first transmission member 231 rotates in the same direction as the rotating member 210. Due to the meshing of the first gear 2322 and the first transmission member 231, the first gear 2322, the second gear 2323, and the gear shaft 2321 rotate away from the first direction. Under the meshing of the rack 310 and the second gear 2323, the blocking member 300 can move away from the first insertion port 101 to open the first insertion port 101.

[0211] Combination Figure 12 As shown, with the shield 300 open at the first insertion port 101, the gear shaft 2321 moves to the middle of the extending direction of the limiting groove 212.

[0212] The first transmission component 231 is an incomplete gear. The periphery of the first transmission component 231 is provided with connected tooth sections and clearance sections.

[0213] Combination Figure 11 As shown, when the blocking member 300 closes the first insertion port 101, the first gear 2322 meshes with the end of the gear tooth segment near the first direction. Figure 12 As shown, when the shielding member 300 opens the first insertion port 101, the first gear 2322 and the end of the gear tooth segment facing away from the first direction mesh.

[0214] Combination Figure 13 As shown, when it is necessary to increase the baking intensity, the rotating part 210 can be rotated along the first direction, and the gear shaft 2321 moves from the middle of the extension direction of the limiting groove 212 to the second end of the extension direction of the limiting groove 212 until the limiting part 111 is connected to the third positioning part 2113.

[0215] During this process, the first gear 2322 and the tooth segment are disengaged, and the position of the first gear 2322 corresponds to that of the avoidance segment. Therefore, the rotation of the rotating member 210 and the first transmission member 231 will not drive the second transmission member 232 to move, and thus will not cause the blocking member 300 to move. During this process, the position of the blocking member 300 remains unchanged. Rotating the rotating member 210 can only connect the limiting member 111 and the third positioning part 2113, thereby only changing the heating mode.

[0216] With this configuration, as the rotating component 210 rotates, the limiting component 111 will undergo elastic deformation on the inner wall of the mounting hole 211 and at each positioning part, which can optimize the rotation feel and realize the gear switching function.

[0217] In some embodiments, the limiting groove 212 is an arc-shaped groove, and the center of the arc-shaped groove coincides with the axis of the rotating member 210.

[0218] The shape of the limiting groove 212 can be adapted to the trajectory of the gear shaft 2321 relative to the rotating part 210, ensuring that the rotating part 210 can rotate smoothly and the gear shaft 2321 can also rotate smoothly, reducing friction and wear.

[0219] In some embodiments, the shield 300 is provided with a relief groove 302. When the shield 300 moves relative to the main body 100 to open the first insertion port 101, the gear shaft 2321 is embedded in the relief groove 302.

[0220] The design of the clearance groove 302 provides space for the gear shaft 2321 during the movement of the blocking member 300, so that the gear shaft 2321 will not interfere with the movement of the blocking member 300, and ensure that the blocking member 300 can move smoothly without obstruction.

[0221] Specifically, when the blocking member 300 moves to open the first insertion port 101, the gear shaft 2321 is embedded in the relief groove 302. This design allows the gear shaft 2321 to move freely without interfering with the blocking member 300, ensuring that the opening and closing operation of the blocking member 300 can be carried out smoothly.

[0222] In summary, the aerosol generating device provided in this application embodiment achieves precise opening and closing and gear switching of the blocking member 300 at the first insertion port 101 through the coordinated action of various components in the driving assembly 200. Combined with the cooperation of the limiting member 111 and the positioning part, it can limit the position of the driving assembly 200, ensuring that the blocking member 300 can be stably maintained in the predetermined position when the first insertion port 101 is closed or opened, thereby avoiding the positional displacement of the blocking member 300 due to external force or wear, and ensuring the stability and reliability of the blocking member 300.

[0223] Specifically, the rotating component 210 cooperates with the rotating shaft 110 of the main body 100 to ensure the fixed-axis rotation of the rotating component 210; the guide component cooperates with the drive assembly 200 to realize the uniqueness and controllability of the movement path of the blocking component 300; at the same time, the positioning part moves in conjunction with the limiting component 111 as the rotating component 210 rotates, which not only realizes the accuracy and reliability of gear switching, but also optimizes the rotation feel. Users can operate the mechanism to open and close and switch modes with one hand, effectively improving the user experience and operating efficiency of the product.

[0224] Finally, it should be noted that those skilled in the art, upon considering the specification and practicing the application disclosed herein, will readily conceive of other embodiments of the present application. The embodiments of this application are intended to cover any variations, uses, or adaptations of the embodiments of this application that follow the general principles of the embodiments of this application and include common knowledge or customary technical means in the art not disclosed in the embodiments of this application.
