[0038] See also Figure 1 The aerosol generating device 100 is a structure that can generate aerosol by acting on the aerosol generating matrix 200 through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical vibration. The aerosol generating matrix 200 is a plant leaf product that has been processed and heated to generate aerosol. The form of the aerosol generating matrix 200 can be fully solid or semi-solid. In the case where the aerosol generating matrix 200 is fully solid, the aerosol generating matrix 200 can be prepared by rolling, slurrying, die casting, extrusion and other process methods. The aerosol generating matrix 200 can be a cylindrical structure similar to a cigarette, or it can be a sheet structure, a strip structure or a block structure. In this application, the aerosol generating matrix is ​​such as Figure 1 The cylindrical structure shown is used as an example for explanation.

[0039] The aerosol-generating substrate is heated and atomized to form an aerosol, which may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The user can inhale the aerosol into the oral cavity, nasal cavity or lungs through the mouth or nose, and the aerosol inhaled into the user's respiratory system can be used for a variety of purposes such as food, medicine, and health care.

[0040] In the related art, the knob is configured to drive multiple movable parts to move toward the center of the loading hole to cover or open the loading hole when it is rotated. The structure is relatively complex, and multiple movable parts are closed toward the center, which may easily cause loose closure and poor dustproof stability.

[0041] See also Figure 2-Figure 4The aerosol generating device 100 of the embodiment of the present application includes a housing 10, a movable member 20, an upper cover 30 and a knob 40, wherein the housing 10 is formed with a loading hole 101, the movable member 20 is slidably disposed on the housing 10, the upper cover 30 is disposed on the housing 10, and the knob 40 is rotatably disposed on the upper cover 30. The knob 40 is connected to the movable member 20, and the knob 40 is provided with a through hole 401, and the through hole 401 and the loading hole 101 correspond to and communicate with each other along the depth direction of the through hole 401. The knob 40 is configured to rotate along a first direction w to drive the movable member 20 to slide to cover the loading hole 101, and to rotate along a second direction v to drive the movable member 20 to slide to open the loading hole 101. The first direction w and the second direction v are opposite directions.

[0042] In the aerosol generating device 100 of the embodiment of the present application, the knob 40 is connected to the movable part 20 and is rotatably arranged on the upper cover 30. By rotating the knob 40, the movable part 20 can be driven to slide to cover or open the loading hole 101, so that the user can rotate the knob 40 to open the loading hole 101 to insert the aerosol generating matrix. When the loading hole 101 is not in use, the knob 40 is rotated to cover it to prevent dust and other foreign matter from entering the loading hole 101. Such a rotating dustproof component has a simple structure and high stability. In addition, the through hole of the knob 40 is directly opposite to and connected to the loading hole 101, and the structure is compact, which is conducive to the miniaturization of the aerosol generating device 100.

[0043] Specifically, the housing 10 may be a generally cylindrical structure, and components such as a battery (not shown), a control component (not shown), and a heating element (not shown) may be installed inside the housing 10. The cross-sectional shape of the outer contour of the housing 10 includes, but is not limited to, a circle, an ellipse, a racetrack, a rectangle, a triangle, a regular polygon, and other irregular polygons. This application only takes the cross-sectional shape of the outer contour of the housing 10 as an example. Figure 2 The runway shape shown is used as an example for explanation.

[0044] In some embodiments, the housing 10 may be made of a material with high thermal conductivity, such as a metal or alloy material such as copper, aluminum, etc., so that the heat of the components inside the housing 10 can be quickly dissipated, and the texture of the entire aerosol generating device 100 can be improved. In other embodiments, the housing 10 may be at least partially made of other materials with good thermal conductivity, for example, the housing 10 is made of ceramics, high thermal conductivity plastics, etc.

[0045] See also Figure 3 and Figure 4The shell 10 includes a top 11, a bottom 12 and a side wall 13. The top 11 and the bottom 12 are opposite to each other and connected by the side wall 13. The top 11, the bottom 12 and the side wall 13 may be formed on different structural members constituting the shell 10. The distance between the top 11 and the bottom 12 may be greater than the distance between any two side walls 13. The loading hole 101 is opened at the top 11. The loading hole 101 penetrates the top 11 and goes deep in the direction from the top 11 to the bottom 12, connecting the interior of the shell 10 with the external environment. The bottom 12 may form a closure for the loading hole 101. In this application, the direction from the top 11 to the bottom 12 is taken as the direction from top to bottom, which is also the depth direction D of the loading hole 101. When the movable part 20 opens the loading hole 101, the aerosol generating matrix can be inserted into the loading hole 101 from top to bottom.

[0046] The movable part 20, the upper cover 30 and the knob 40 are arranged on the side of the top 11 of the shell 10 away from the bottom 12. The knob 40, the upper cover 30 and the movable part 20 can be arranged in sequence from top to bottom. The sliding direction of the movable part 20 intersects with the depth direction of the loading hole 101, and the angle between the sliding direction of the movable part 20 and the depth direction D of the loading hole 101 can be any other angle value other than zero and 180°. Exemplarily, the sliding direction of the movable part 20 can be perpendicular to the depth direction D of the loading hole 101, that is, the angle between the sliding direction of the movable part 20 and the direction from the top 11 to the bottom 12 is 90°.

[0047] The upper cover 30 can cover the top 11 of the housing 10, and the cross-sectional shape of the outer contour of the upper cover 30 can be consistent with the housing 10, so that the outer wall surface of the aerosol generating device 100 as a whole is not easy to form a step. For example, the cross-sectional shape of the outer contour of the upper cover 30 is as follows: Figure 2 The upper cover 30 is stacked on the top 11 of the housing 10, and the upper cover 30 is provided with a through hole 301, which can penetrate from the side surface of the upper cover 30 away from the housing 10 to the side surface of the upper cover 30 facing the housing 10, and the depth direction of the through hole 301 is consistent with the depth direction D of the loading hole 101.

[0048] Combination Figure 6 and Figure 7 , Figure 6 FIG. 1 is a top view of a portion of the structure of the aerosol generating device 100 at the upper cover 30 when the movable member 20 completely opens the loading hole 101. Figure 7It is a top view of the partial structure of the aerosol generating device 100 at the upper cover 30 when the movable member 20 completely covers the loading hole 101. When the knob 40 rotates along the first direction w, the movable member 20 is driven to slide along the first sliding direction, and the movable member 20 moves from the side of the loading hole 101 below the upper cover 30 to the position facing the loading hole 101, thereby covering the loading hole 101. When the knob 40 rotates along the second direction v, the movable member 20 is driven to slide in the second sliding direction, and the movable member 20 moves from the position above the loading hole 101 facing the loading hole 101 to the side of the loading hole 101, thereby opening the loading hole 101. The first sliding direction and the second sliding direction can be perpendicular to the direction from the top 11 to the bottom 12, and can be opposite directions between two side walls 13 with a larger distance.

[0049] See also Figure 3-Figure 5 In some embodiments, the upper cover 30 is formed with a through hole 301, and the through hole 301 is directly opposite to the loading hole 101 along the depth direction of the through hole 301 to accommodate the insertion of the aerosol generating matrix.

[0050] In this way, the space at the top of the aerosol generating device 100 can be saved, which is conducive to a compact structure.

[0051] Specifically, the knob 40 as a whole can be a rotating body in the shape of a disk, a column, a sphere, a hemisphere, etc., and a through hole 401 can be formed in the center of the knob 40, which passes through the knob 40 from top to bottom. The through hole 401 and the loading hole 101 can be directly opposite and connected along the depth direction of the through hole 401. This application only takes the knob 40 as an example. Figure 3 The knob 40 rotates with the depth direction D of the loading hole 101 as the rotation axis, and can rotate parallel to the upper cover 30 and the top 11 of the housing 10. The first direction w can be clockwise or counterclockwise, and the second direction v is the direction opposite to the first direction w between the clockwise direction and the counterclockwise direction. For ease of description, in this application, the first direction w is the counterclockwise direction and the second direction v is the clockwise direction.

[0052] The knob 40 may be disposed at a position facing the loading hole 101 on the side of the upper cover 30 away from the housing 10. The through hole 401 of the knob 40, the through hole 301 of the upper cover 30, and the loading hole 101 inside the housing 10 may be connected from top to bottom. The loading hole 101 can only be blocked by the movable member 20 in the depth direction, so that the closing and opening of the loading hole 101 can be controlled by sliding the movable member 20.

[0053] See also Figure 3 and Figure 4 In some embodiments, the upper cover 30 is provided with a mounting hole 302 , and the mounting hole 302 is used to install the functional component 31 , and the functional component 31 is spaced apart from the knob 40 .

[0054] In this way, the upper cover 30 can accommodate the insertion of the aerosol generating matrix while installing other functional parts 31. The upper cover 30, the knob 40, the movable part 20 and the other functional parts 31 can all be arranged on the top 11 of the aerosol generating device 100, thereby improving the structural space utilization of the aerosol generating device 100.

[0055] Specifically, the mounting hole 302 can be located at one end of the upper cover 30 away from the through hole 301, avoiding the loading hole 101 and the movable part 20. The functional part 31 and the knob 40 can be arranged at intervals along the sliding direction of the movable part 20. The mounting hole 302 can be installed with the functional part 31 to control the aerosol generating device 100. The functional part 31 can be a switch button of the aerosol generating device 100. The user can start or shut down the aerosol generating device 100 by pressing the functional part 31. The functional part 31 can be some indicative elements or functional ports. For example, the mounting hole 302 can be installed with a light source. When the aerosol generating device 100 is working, the light source lights up, which can enhance the aesthetics and interest of the aerosol generating device. For another example, the mounting hole 302 can be installed with a charging interface, a data card interface or a display screen to realize the charging, storage or real-time status display function of the aerosol generating device 100.

[0056] The aerosol generating device 100 of the embodiment of the present application has a compact structure by providing a through hole 301 on the upper cover 30 that is opposite to the loading hole 101 in the depth direction D, a knob 40 that is opposite to the loading hole 101, and a movable part 20 that is stacked with the upper cover 30. In addition, a mounting hole 302 can be formed on the upper cover 30 to accommodate other functional parts 31, thereby effectively utilizing the internal space of the aerosol generating device 100 and helping to reduce the overall volume of the aerosol generating device 100.

[0057] See also Figure 3 In some embodiments, the housing 10 forms a limiting groove 14 , and the movable member 20 is at least partially disposed in the limiting groove 14 .

[0058] In this way, the position of the movable part 20 can be limited by the limiting groove 14, thereby improving the stability of the movable part 20 and ensuring the dustproof effect.

[0059] Specifically, the limiting groove 14 can be formed on the side of the top 11 of the shell 10 away from the bottom 12, and is located above the loading hole 101. The bottom surface of the limiting groove 14 can jointly define the position of the movable part 20 in the depth direction D of the loading hole 101 with the bottom surface of the upper cover 30. The bottom surface of the limiting groove 14 is also the partial surface of the shell 10 on the side of the loading hole 101 facing the upper cover 30, and the bottom surface of the upper cover 30 is also the side surface of the upper cover 30 facing the shell 10. The top 11 is formed with a convex edge 141 protruding from the side surface of the top 11 away from the bottom 12 toward the upper cover 30, the inner side of the convex edge 141 can be in contact with the edge of the movable part 20, and the upper edge of the convex edge 141 can be close to the bottom surface of the upper cover 30. The convex edge 141 can limit the position of the movable part 20 on the bottom surface of the limiting groove 14. For example, the flange 141 may be disposed at a connection between the top 11 and two opposite side walls 13 , and the movable member 20 is confined between the two opposite side walls 13 .

[0060] The movable member 20 can limit the sliding direction by setting a slide rail 142 and a slide groove between the limit groove 14 and the movable member 20. Figure 3 In the illustrated embodiment, the slide rail 142 may be formed on the bottom surface of the limiting groove 14, and the slide rail 142 may extend in a direction parallel to the side wall 13 of the housing 10. Accordingly, the slide groove (not shown) is formed on the side surface of the movable member 20 facing the housing 10. In other embodiments, the slide rail 142 may be formed on the side surface of the movable member 20 facing the housing 10, and the slide groove (not shown) is formed on the bottom surface of the limiting groove 14.

[0061] See also Figure 3 and Figure 4 In some embodiments, the housing 10 includes a bracket 15 and a connecting member 16 , the connecting member 16 forms a limiting groove 14 and a partial loading hole 101 , the bracket 15 forms a partial loading hole 101 , and the movable member 20 is located on a side of the connecting member 16 away from the bracket 15 .

[0062] In this way, the connection member 16 and the bracket 15 cooperate to make the structure of the housing 10 more stable, and the structure of the housing 10 is easier to implement.

[0063] Specifically, the housing 10 further includes a shell 17. The shell 17 may form an opening and surround the bracket 15 and the connector 16, forming an outer contour surface of the aerosol generating device 100. The connector 16 includes a side connector 162 and an upper connector 161, the side connector 162 is attached to the inner wall of the housing 17, and the upper connector 161 may form the top 11 of the housing 10 and cover the opening of the housing 17. The upper cover 30 is stacked on the side of the upper connector 161 away from the bottom 12, and the outer contour line of the upper cover 30 may be flush with the outer contour line of the upper connector 161. The upper connector 161 may be fixedly connected to the upper cover 30 by at least one of snap connection, fixing member connection, gluing connection and welding. The loading hole 101 penetrates the upper connector 161 along the direction from the upper connector 161 to the bottom 12, and penetrates into the bracket 15. The bracket 15 may be hollow tubular as a whole, forming part of the peripheral wall of the loading hole 101. The support 15 can support the aerosol generating substrate inserted into the loading hole 101 and limit the position of the aerosol generating substrate. The support 15 abuts against a side surface of the upper connecting member 161 facing the bottom 12 and is sealedly connected to the upper connecting member 161.

[0064] The movable member 20 is located on the side of the upper connecting member 161 away from the bracket 15, and the movable member 20 is fixed between the side surface of the upper cover 30 facing the bottom 12 and the side surface of the upper connecting member 161 away from the bottom 12 in the depth direction D of the loading hole 101. A limiting groove 14 is formed on the side of the upper connecting member 161 away from the bracket 15, and the movable member 20 can slide in the limiting groove 14.

[0065] See also Figure 5 In some embodiments, the knob 40 includes a body 41 and a protrusion 42 disposed on the body 41, the movable part 20 is provided with a connecting hole 201, and the protrusion 42 is disposed in the connecting hole 201. During the rotation of the body 41, the protrusion 42 and the connecting hole 201 cooperate to drive the movable part 20 to slide.

[0066] In other embodiments, the knob 40 is provided with a connecting hole 201 , and the movable member 20 is provided with a protrusion 42 , and the protrusion 42 is disposed in the connecting hole 201 . During the rotation of the knob 40 , the protrusion 42 and the connecting hole 201 cooperate to drive the movable member 20 to slide.

[0067] In this way, the rotating knob 40 drives the movable part 20 to slide through the cooperation between the protrusion 42 and the connecting hole 201 , which has a simple structure and high reliability.

[0068] Specifically, the body 41 includes a coaxial first ring 411 and a second ring 412, which are stacked together from top to bottom, and the radius of the first ring 411 may be greater than the radius of the second ring 412. The second ring 412 may extend into the through hole 301 of the upper cover 30, and a protrusion 42 is formed on one side of the second ring 412 facing the top 11 of the housing 10. The protrusion 42 may extend from the surface of the second ring 412 toward the top 11 of the housing 10, and pass through the connection hole 201 formed on the movable member 20.

[0069] A rotating piece 413 may be formed on the outer circumferential surface of the second ring 412. The rotating piece 413 may extend radially outwardly from the second ring 412 and engage with the upper cover 30. A clamping platform 32 may be formed on the inner wall of the through hole 301 and extend circumferentially from the through hole 301. The clamping platform 32 may be semicircular and engage with the rotating piece 413 up and down. When the knob 40 is rotated, the rotating piece 413 may rotate against the clamping platform 32. The protrusion 42 may be formed on the rotating piece 413.

[0070] The width of the connection hole 201 may be close to the diameter of the protrusion 42, and the length of the connection hole 201 may be significantly greater than the diameter of the protrusion 42. The length direction of the connection hole 201 may form a certain angle with the rotation direction of the body 41, so that when the body 41 rotates, the protrusion 42 may move in the connection hole 201 relative to the movable part 20 along the length direction of the connection hole 201. It can be understood that when the body 41 rotates, the protrusion 42 cooperates with the connection hole 201 to decompose the rotation of the body 41 into a linear motion along the tangential and radial directions, the protrusion 42 moves along the length direction of the connection hole 201 relative to the movable part 20, and the movable part 20 moves in a direction perpendicular to the length direction of the connection hole 201.

[0071] The illustration of the embodiment of the present application only illustrates that the protrusion 42 is formed on the knob 40 and the connecting hole 201 is formed on the movable part 20, but this should not be regarded as a limitation of the present application. In other embodiments, the protrusion 42 can be provided on the side surface of the movable part 20 facing the knob, and the protrusion 42 extends toward the side away from the housing 10 and passes through the connecting hole 201 on the knob 40. The movable part 20 abuts against the knob 40 through the protrusion 42, and the protrusion 42 can be movably provided in the connecting hole 201. When the knob 40 rotates, the movable part is driven to move radially along the knob 40 through the cooperation of the protrusion 42 and the connecting hole 201.

[0072] Please continue reading Figure 5In some embodiments, the aerosol generating device 100 includes a first magnetic member 51, a second magnetic member 52 and a third magnetic member 53. The first magnetic member 51 and the second magnetic member 52 are arranged on the knob 40 at intervals along the circumference of the knob 40, and the third magnetic member 53 is arranged on the upper cover 30. When the movable member 20 opens the loading hole 101, the first magnetic member 51 and the third magnetic member 53 are aligned along the radial direction of the knob 40 and attract each other. When the movable member 20 covers the loading hole 101, the second magnetic member 52 and the third magnetic member 53 are aligned along the radial direction of the knob 40 and attract each other.

[0073] In this way, the first magnetic member 51 and the third magnetic member 53 as well as the second magnetic member 52 and the third magnetic member 53 alternately attract each other during the sliding process of the movable member 20, so that the sliding of the movable member 20 has a certain resistance or assistance, and can assist in positioning the sliding position of the movable member 20.

[0074] Specifically, the first magnetic member 51 and the second magnetic member 52 have the same magnetic properties, and have different magnetic properties from the third magnetic member 53. The first magnetic member 51 and the second magnetic member 52 can be permanent magnets of the N pole, and the corresponding third magnetic member 53 is a permanent magnet of the S pole. The first magnetic member 51 and the second magnetic member 52 can be permanent magnets of the S pole, and the corresponding third magnetic member 53 is a permanent magnet of the N pole. In some embodiments, the first magnetic member 51, the second magnetic member 52, and the third magnetic member 53 can obtain different magnetic properties through electromagnetic induction.

[0075] The third magnetic member 53 can be arranged in the shell 10 or the upper cover 30 that are relatively fixedly connected, and the first magnetic member 51 and the second magnetic member 52 can be arranged in the knob 40 and the movable member 20 that move relative to the shell 10 and the upper cover 30. The first magnetic member 51 and the second magnetic member 52 are arranged at intervals along the circumference of the knob 40 and move with the rotation of the knob 40. The first magnetic member 51 and the third magnetic member 53 can be configured to be closest to each other and have the strongest attraction when the movable member 20 slides to a position that completely releases the loading hole 101. The second magnetic member 52 and the third magnetic member 53 can be configured to be closest to each other and have the strongest attraction when the movable member 20 slides to a position that completely covers the loading hole 101.

[0076] See also Figure 5-Figure 9 In some embodiments, the first magnetic member 51 and the second magnetic member 52 are accommodated in the knob 40 .

[0077] In this way, by accommodating the first magnetic component 51 and the second magnetic component 52 in the knob 40, the rotation of the knob 40 directly affects the distance and attraction between the first magnetic component 51 and the second magnetic component 52 and the third magnetic component 53, so that the user feels a certain damping when rotating the knob 40, thereby improving the user experience.

[0078] Specifically, two first magnetic members 51 and second magnetic members 52 with the same magnetic properties can be disposed in the knob 40, and the positions of the first magnetic member 51 and the second magnetic member 52 form a certain angle with the line connecting the center of the knob 40. The third magnetic member 53 has opposite magnetic properties to the first magnetic member 51 and the second magnetic member 52, and the third magnetic member 53 can be disposed at a position where the upper cover 30 is tangent to the outer periphery of the first ring 411. Figure 6 and Figure 8 As shown, when the movable member 20 completely opens the loading hole 101, the first magnetic member 51 and the third magnetic member 53 are attracted to each other and are at a position where the distance between the first magnetic member 51 and the third magnetic member 53 is the smallest, as shown in FIG. Figure 7 and Fig. 9 As shown, when the movable member 20 completely covers the loading hole 101 , the second magnetic member 52 and the third magnetic member 53 are attracted to each other and are at a position where the distance between the second magnetic member 52 and the third magnetic member 53 is the smallest.

[0079] Please refer again Figure 5 In some embodiments, the upper cover 30 is formed with a receiving groove 33 , and the knob 40 is received in the receiving groove 33 .

[0080] In this way, the knob 40 is accommodated in the upper cover 30 , which can further reduce the volume of the aerosol generating device 100 .

[0081] Specifically, the receiving groove 33 is located above the loading hole 101 and is formed around the through hole 301. The knob 40 is received in the receiving groove 33, the first ring 411 can contact the bottom surface of the receiving groove 33, and the second ring 412 can extend into the through hole 301 and engage with the clamping table 32. The upper edge of the clamping table 32 can partially exceed the bottom surface of the receiving groove 33 and engage with the first ring 411. The outer peripheral surface of the first ring 411 of the knob 40 can form a decorative groove in various shapes such as strip, wave, circle, square, etc., and multiple decorative grooves can be compactly arranged along the circumference of the first ring 411 to increase the friction force of the outer periphery of the first ring 411, so as to facilitate hand-held operation.

[0082] See also Figure 1 and Figure 5 In some embodiments, the top surface of the knob 40 is flush with the top surface of the upper cover 30 .

[0083] In this way, the top surface of the knob 40 is flush with the top surface of the upper cover 30 , thereby reducing the difference in the overall outer contour of the aerosol generating device 100 .

[0084] Specifically, the top surface of the upper cover 30 may be a side surface away from the bracket 15 along the depth direction D of the loading hole 101, and a partial surface deviating from the loading hole 101 and the through hole 301. The top surface of the upper cover 30 may form the appearance surface of the aerosol generating device 100, and may be formed with a mounting hole 302. The top surface of the upper cover 30 and the bottom surface of the receiving groove 33 have a height difference along the depth direction D of the loading hole 101. The knob 40 is received in the receiving groove 33, and the top surface of the knob 40 is flush with the top surface of the upper cover 30, making up for the height difference between the bottom surface of the receiving groove 33 and the top surface of the upper cover 30. Part of the outer peripheral surface of the knob 40 may be flush with the arc surface of the runway-shaped upper cover 30.
