[0002] An aerosol generating device is a small device that can use the Heat Not Burning (HNB) technology to act on an aerosol generating substrate and generate an aerosol. Specifically, the aerosol generating device usually heats the aerosol generating substrate to a temperature that can generate an aerosol but is not high enough to burn, so that the aerosol generating substrate can generate an aerosol for the user to inhale without burning. The aerosol generating device can ensure the original taste of the aerosol generating substrate and effectively control the generation of harmful substances. As people pay more and more attention to health, aerosol generating devices have gradually become people's first choice.

[0003] In order to prevent foreign matter from falling into the aerosol generating device and generating harmful substances that affect human health when heated, the aerosol generating device is usually provided with a shielding component.

When the shielding member is in a first position covering the loading hole, the limiting member interacts with the matching member to limit the shielding member to be in the first position, and when the shielding member is in a second position opening the loading hole, the limiting member interacts with the matching member to limit the shielding member to be in the second position.

[0006] In some embodiments, the shielding assembly further includes a toggle member, which is at least partially exposed from the side wall of the shell, and the toggle member can drive the shielding member to rotate, translate, or rotate and translate relative to the shell and the cover body under the action of an external force.

[0008] In some embodiments, the matching member is disposed on a side wall of the toggle member, and the limiting member is disposed on the shell or the cover.

[0009] In some embodiments, the limiting member and the matching member are in contact and cooperate with each other to limit the shielding member to be in the first position or the second position.

[0010] In some embodiments, the limiting member is a retractable structure, the limiting member includes a protruding limiting portion, the limiting assembly includes two mating members, the mating members are grooves on the side walls of the toggle member, the limiting portion engages with one of the grooves to limit the shielding member to the first position, and the limiting portion engages with the other groove to limit the shielding member to the second position.

[0011] In some embodiments, the position-limiting member further comprises a mounting portion and an elastic portion.

[0034] In order to prevent foreign matter from falling into the aerosol generating device and generating harmful substances that affect human health when heated, the aerosol generating device is usually provided with a shielding component. However, the shielding components currently used in the market are usually arranged outside the aerosol generating device, which affects the integrity and aesthetics of the aerosol generating device. In order to solve this problem, the embodiment of the present application provides an aerosol generating device 100 ( Figure 1 shown).

[0035] See also Figure 1 and Figure 2The aerosol generating device 100 of the embodiment of the present application includes a shell 10, a cover body 30, a shielding assembly 50 and a limiting assembly 70. The shell 10 is provided with a loading hole 11, and the loading hole 11 is used to load the aerosol generating product. The cover body 30 is installed on the shell 10, and is provided with a through hole 31 corresponding to the loading hole 11. The shielding assembly 50 is arranged between the shell 10 and the cover body 30, and the shielding assembly 50 includes a shielding member 51, and the shielding member 51 can move relative to the shell 10 and the cover body 30 under the action of an external force. The limiting assembly 70 includes a limiting member 71 and a matching member 73, one of the limiting member 71 and the matching member 73 is arranged on the shielding assembly 50, and the other is arranged on the shell 10 or the cover body 30, and the limiting member 71 and the matching member 73 have an intersection in the height direction H of the aerosol generating device 100. When the shielding member 51 is in the first position ( Figure 3 As shown in FIG. 1 , the stopper 71 interacts with the mating member 73 to limit the shielding member 51 to be in the first position. When the shielding member 51 is in the second position ( FIG. 1 ) of the opening loading hole 11, Figure 4 The limiting member 71 interacts with the matching member 73 to limit the shielding member 51 to be in the second position.

[0036] Specifically, the aerosol generating device 100 is a structure that can generate aerosols by acting on an aerosol generating substrate through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical oscillation. For example, the aerosol generating device 100 generates aerosols by heating an aerosol generating product using microwave radiation. Aerosols can be visible or invisible and may include vapor (for example, 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 aerosol generating product is a product loaded with an aerosol generating substrate, and the shell of the aerosol generating product is not limited to a paper shell, a plastic shell or a metal shell, etc., and the aerosol generating substrate is loaded in the shell of the aerosol generating product. The aerosol generating substrate is a plant leaf product that has been processed and heated to generate an aerosol. The form of the aerosol generating substrate can be fully solid or semi-solid. In the case where the aerosol generating substrate is fully solid, the aerosol generating substrate can be prepared by rolling, thick slurry, die casting, extrusion and other process methods. The aerosol generating substrate may be a cylindrical structure similar to a cigarette, or may be a sheet structure, a strip structure or a block structure.

[0037] The shell 10 is a structure for accommodating other components. In the present application, the shell 10 is used to accommodate the heating element, circuit board, control element, power supply unit, etc. of the aerosol generating device 100. The material of the shell 10 may be, but is not limited to, metal, plastic, or ceramic. When the material of the shell 10 is metal, the structural strength of the shell 10 is high, it is not easy to be damaged, and the service life is long; when the material of the shell 10 is plastic, the weight of the shell 10 is light, it is easy to carry, and the cost is low; when the material of the shell 10 is ceramic, the hardness of the shell 10 is high, it is not easy to deform, and it has good corrosion resistance and a long service life. The cross-section of the shell 10 may be, but is not limited to, circular, elliptical, rectangular, etc.

[0038] The loading hole 11 is a spatial structure for loading other components therein. When the aerosol generating device 100 is to be inhaled, the aerosol generating product needs to be loaded into the loading hole 11 first. In the inner cavity of the housing 10, the control element controls the heating element to heat the aerosol generating product to generate an aerosol for the user to inhale. When the aerosol generating product is completely inhaled, the aerosol generating product needs to be taken out of the loading hole 11 to facilitate loading a new aerosol generating product into the loading hole 11 for the next inhalation. The opening shape of the loading hole 11 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral or other polygons.

[0039] The cover 30 is used to cover the top opening of the shell 10, and the through hole 31 of the cover 30 corresponds to and communicates with the loading hole 11 of the shell 10. The material of the cover 30 can be, but is not limited to, metal, plastic or ceramic. When the material of the cover 30 is metal, the structural strength of the cover 30 is high, not easy to be damaged, and has a long service life; when the material of the cover 30 is plastic, the weight of the cover 30 is light, easy to carry, and the cost is low; when the material of the cover 30 is ceramic, the hardness of the cover 30 is high, not easy to deform, and has good corrosion resistance and a long service life. The material of the cover 30 can be the same as that of the shell 10, or it can be different. The cross-sectional shape of the cover 30 is basically consistent with the cross-sectional shape of the shell 10, so that the cover 30 and the shell 10 are firmly connected.

[0040] The through hole 31 is used for the aerosol generated by heating the aerosol generating product in the loading hole 11 to flow out of the through hole 31 for inhalation by the user. The opening shape of the through hole 31 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral or other polygons. The opening shape of the through hole 31 can be the same as or different from the opening shape of the loading hole 11, and the cross-sectional area of ​​the through hole 31 can be the same as or different from the cross-sectional area of ​​the loading hole 11, as long as the through hole 31 is connected to the loading hole 11.

[0041] The shielding assembly 50 is a structure that can move to cover the target element. For example, the shielding assembly 50 can move relative to the shell 10 and the cover body 30 under the action of external force to cover or open the loading hole 11. The shielding member 51 can cover or open the loading hole 11 by rotating or translating relative to the shell 10 and the cover body 30. The cross-sectional shape of the shielding member 51 can be, but is not limited to, circular, elliptical, quadrilateral or other polygonal. The cross-sectional area of ​​the shielding member 51 is the same as the cross-sectional area of ​​the loading hole 11 and the through hole 31, or the cross-sectional area of ​​the shielding member 51 is larger than the cross-sectional area of ​​the loading hole 11 and the through hole 31. In the case where the loading hole 11 needs to be covered, the shielding member 51 is located between the loading hole 11 and the through hole 31, and the shielding member 51 is used to separate the loading hole 11 and the through hole 31 to prevent foreign matter from entering the loading hole 11 from the through hole 31.

[0042] The limiter assembly 70 is a structure for limiting the movement of the shielding assembly 50, and the limiter 71 and the matching member 73 cooperate to limit the shielding assembly 51 to remain in the first position and the second position. In one embodiment, the limiter 71 is disposed on the housing 10, and the matching member 73 is disposed on the shielding assembly 50. In another embodiment, the limiter 71 is disposed on the cover body 30, and the matching member 73 is disposed on the shielding assembly 50. In still another embodiment, the limiter 71 is disposed on the shielding assembly 50, and the matching member 73 is disposed on the housing 10. In yet another embodiment, the limiter 71 is disposed on the shielding assembly 50, and the matching member 73 is disposed on the cover body 30. In the embodiment of the present application, the limiter 71 is disposed on the housing 10, and the matching member 73 is disposed on the shielding assembly 50.

[0043] Please combine Figure 3 and Figure 4 When the shielding member 51 is in the first position covering the loading hole 11, the limiting member 71 cooperates with the matching member 73 to generate a first limiting force, which is used to limit the shielding member 51 from moving toward the second position, so that the shielding member 51 can be stably in the first position to cover the loading hole 11. When the shielding member 51 is in the second position opening to cover the loading hole 11, the limiting member 71 cooperates with the matching member 73 to generate a second limiting force, which is used to limit the shielding member 51 from moving toward the first position, so that the shielding member 51 can be stably in the second position to open the loading hole 11, thereby facilitating the user to inhale the aerosol.

[0044] The intersection of the limiter 71 and the matching member 73 in the height direction H of the aerosol generating device 100 means that: in the height direction H of the aerosol generating device 100, at least part of the structure of the limiter 71 and at least part of the structure of the matching member 73 have the same height. In one embodiment, the partial structure of the limiter 71 and the partial structure of the matching member 73 have the same height. At this time, the installation of the limiter 71 and the matching member 73 is relatively simple, and it is only necessary that the limiter 71 and the matching member 73 have partial structures with the same height. In another embodiment, the limiter 71 and the matching member 73 have the same height, that is, the limiter 71 and the matching member 73 are located at the same height. When the limiter 71 and the matching member 73 are located at the same height, the first limiting force and the second limiting force generated between the limiter 71 and the matching member 73 are forces perpendicular to the height direction H of the aerosol generating device 100. At this time, when the shielding member 51 needs to be moved from the first position to the second position, a force opposite to the first limiting force is applied to the shielding member 51, so that the shielding member 51 can be moved to the second position. When the shielding member 51 needs to be moved from the second position to the first position, a force opposite to the second limiting force is applied to the shielding member 51, so that the shielding member 51 can be moved to the second position. The switch of the loading hole is simple and easy to control.

[0045] In the aerosol generating device 100 of the present application, the shielding component 50 is located between the housing 10 and the cover 30, so that the integrity and aesthetics of the aerosol generating device 100 are better. In addition, the aerosol generating device 100 is provided with a stopper 71 and a matching member 73, and the stopper 71 and the matching member 73 cooperate with each other. When the loading hole 11 needs to be blocked, the shielding component 51 can be stably in the first position, and when the loading hole 11 needs to be opened, the shielding component 51 can be stably in the second position, thereby preventing the shielding component 51 from shaking between the housing 10 and the cover 30.

[0046] The aerosol generating device 100 is further described below with reference to the accompanying drawings.

[0047] See also Figures 2 to 4 In some embodiments, the shielding assembly 50 also includes a toggle member 53, which is at least partially exposed from the side wall of the shell 10. The toggle member 53 can drive the shielding member 51 to rotate, translate, or rotate and translate relative to the shell 10 and the cover body 30 under the action of external force.

[0048] The toggle member 53 is used to drive the shielding member 51 to rotate or move relative to the housing 10 and the cover 30, so that the shielding member 51 switches between the first position and the second position. The toggle member 53 and the shielding member 51 can be an integral structure or a split structure. When the toggle member 53 and the shielding member 51 are an integral structure, the toggle member 53 and the shielding member 51 are made of the same material. When the toggle member 53 and the shielding member 51 are split structures, the toggle member 53 is detachably or non-detachably connected to the shielding member 51. The detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit.

[0049] The toggle member 53 includes a toggle portion 531 and a column portion 533. The column portion 533 is connected to the shielding member 51. The column portion 533 of the present application is used to drive the shielding member 51 to rotate so that the shielding member 51 switches between the first position and the second position. The toggle portion 531 is exposed from the housing 10 so that the user can apply force to the toggle portion 531 so that the toggle member 53 drives the shielding member 51 to switch between the first position and the second position.

[0050] In one embodiment, the toggle portion 531 protrudes from the perforation of the side wall of the housing 10. In this case, the shielding assembly 50 of the aerosol generating device 100 is easy for the user to manipulate. The user can apply an external force to the toggle portion 531 protruding from the side wall of the housing 10, thereby driving the shielding member 51 to move. In another embodiment, the toggle portion 531 corresponds to the perforation of the side wall of the housing 10. In this case, the overall structure of the aerosol generating device 100 is small, easy to carry, and more beautiful. The user can control the toggle portion 531 by passing an object such as a thimble through the perforation.

[0051] See also Figures 2 to 4 In some embodiments, the toggle member 53 is columnar and rotatably connected to the cover 30 and / or the housing 10, and the shielding member 51 is disposed at one end of the toggle member 53 along the height direction H of the aerosol generating device 100. Specifically, the column portion 533 of the toggle member 53 is a columnar structure so that the toggle member 53 can rotate relative to the cover 30 or the housing 10. The extension direction of the column portion 533 is parallel to the height direction H of the aerosol generating device 100, and the shielding member 51 of the present application is disposed at the top of the column portion 533. After the user applies force to the toggle portion 531, the column portion 533 is subjected to external force and drives the shielding member 51 to rotate together. In one embodiment, the column portion 533 is rotatably connected to the cover 30. In another embodiment, the column portion 533 is rotatably connected to the housing 10.

[0052] See also Figures 2 to 4Further, the shielding assembly 50 also includes a connector 55, one end of which is connected to the housing 10, and the other end of which is connected to the column 533, and the connector 55 is used to make the column 533 rotate relative to the housing 10 and the cover 30. Preferably, the connector 55 is a cylindrical structure, so that the column 533 connected to the connector 55 can rotate relative to the housing 10 and the cover 30. The connector 55 is installed in the second receiving groove 15 of the housing 10, and the connection method between the connector 55 and the housing 10 can be, but is not limited to, threaded connection, snap connection, welding or gluing.

[0053] In one embodiment, the connecting member 55 is fixedly connected to the column portion 533, and the connecting member 55 can drive the column portion 533 to rotate relative to the housing 10. At this time, the user applies an external force to the toggle portion 531, and the connecting member 55 rotates to drive the column portion 533 to rotate, so that the column portion 533 drives the shielding member 51 to switch between the first position and the second position. In another embodiment, the connecting member 55 is fixedly connected to the housing 10, and the column portion 533 can rotate relative to the connecting member 55. At this time, the user applies an external force to the toggle portion 531, and the toggle portion 531 drives the column portion 533 to rotate relative to the connecting member 55, so that the column portion 533 drives the shielding member 51 to switch between the first position and the second position.

[0054] Please continue reading Figure 2 and Figure 4 In some embodiments, during the process of switching the shielding member 51 from the first position to the second position, the limiting force generated by the limiting member 71 and the matching member 73 changes from small to large and then to small.

[0055] Specifically, when the shielding member 51 switches from the first position to the second position, the limiting force between the position-limiting member 71 and the matching member 73 in the first position is relatively small, and when the shielding member 51 is in the middle position between the first position and the second position, the limiting force between the position-limiting member 71 and the matching member 73 is the largest. When the shielding member 51 reaches the second position, the limiting force between the position-limiting member 71 and the matching member 73 gradually decreases. When the user moves the shielding member 51, he or she can feel the process of the limiting force changing from small to large and then to small, thereby knowing whether the shielding member 51 has moved into place.

[0056] See also Figure 5 and Figure 6 In some embodiments, the matching member 73 is disposed on the side wall of the toggle member 53, and the limiting member 71 is disposed on the housing 10 or the cover 30. Specifically, the matching member 73 is disposed on the side wall of the column portion 533 opposite to the limiting member 71. The limiting member 71 can be disposed on the housing 10 or on the cover 10, and the limiting member 71 is opposite to the matching member 73.

[0057] See also Figure 5 and Figure 6In some embodiments, the limiting member 71 and the matching member 73 contact and cooperate with each other to limit the shielding member 51 to the first position or the second position. The limiting member 71 and the matching member 73 cooperate to generate a first limiting force to limit the shielding member 51 to the first position, and the limiting member 71 and the matching member 73 cooperate to generate a second limiting force to limit the shielding member 51 to the second position. In the embodiment of the present application, the limiting member 71 and the matching member 73 conflict with each other to generate the first limiting force and the second limiting force.

[0058] Please continue reading Figure 5 and Figure 6 Specifically, in some embodiments, the limiting member 71 is a retractable structure, and the limiting member 71 includes a protruding limiting portion 711, a mounting portion 713, and an elastic portion 715. The elastic portion 715 is mounted on the mounting portion 713, one end of the elastic portion 715 is connected to the mounting portion 713, and the other end of the elastic portion 715 is connected to the limiting portion 711. When the elastic portion 715 is in a natural state, the limiting portion 711 protrudes toward the matching member 73 relative to the mounting portion 713.

[0059] Specifically, the shielding member 51 of the present application can rotate relative to the shell 10 and the cover body 30, and the limiting portion 711 and the matching member 73 are rotated to match each other so that the shielding member 51 is maintained at the first position and the second position.

[0060] The limiting portion 711 is a structure used to cooperate with the matching member 73 to limit the shielding member 51 to be in the first position and the second position. Preferably, the limiting portion 711 is a spherical structure, so that the shielding member 51 can rotate and cooperate with the limiting portion 711. The limiting portion 711 can be a hollow spherical structure or a solid spherical structure. When the limiting portion 711 is a hollow spherical structure, the limiting portion 711 is light and can save materials. When the limiting portion 711 is a solid spherical structure, the limiting portion 711 has a high structural strength and a long service life.

[0061] The mounting portion 713 is a structure for mounting other components. The mounting portion 713 of the present application is used to mount the elastic portion 715 and the limiting portion 711. The cross-sectional shape of the mounting portion 713 is circular, so that the spherical limiting portion 711 can be mounted on the mounting portion 713. The mounting portion 713 can be mounted in the first receiving groove 13 of the housing 10. When the mounting portion 713 is mounted in the first receiving groove 13, in one example, the opening shape of the first receiving groove 13 can be the same as the cross-sectional shape of the mounting portion 713, so that the mounting portion 713 can be firmly mounted in the first receiving groove 13. In another example, the opening shape of the first receiving groove 13 can be different from the cross-sectional shape of the mounting portion 713. At this time, the mounting portion 713 can be mounted and fixed in the first receiving groove 13 by gluing or welding. The material of the mounting portion 713 can be the same as or different from the material of the limiting portion 711.

[0062] The elastic part 715 can drive other elements connected to it to move by its own extension and contraction. The elastic part 715 of the present application is used to drive the limiter 71 connected to it to move. The elastic part 715 is installed inside the mounting part 713, and the elastic part 715 is detachably or non-detachably connected to the mounting part 713 and the limiter 711. Among them, the detachable installation method includes but is not limited to threaded connection or snap connection. The non-detachable installation method includes but is not limited to welding or gluing connection. The elastic part 715 includes but is not limited to a coil spring or a leaf spring. Among them, the coil spring can be a cylindrical coil spring and a conical coil spring. In the case where the elastic part 715 is a coil spring, the elastic part 715 is small in size and light in weight, which is easy to disassemble and assemble; in the case where the elastic part 715 is a leaf spring, the elastic part 715 has a simpler structure, is more convenient to process, and has a stronger bearing capacity.

[0063] Please continue to read Figure 5 and Figure 6 In some embodiments, the limiting assembly 70 includes two matching pieces 73, the matching piece 73 is a groove 731 on the side wall of the toggle portion 531 of the toggle member 53, the limiting portion 711 engages with one of the grooves 731 to generate a first limiting force to limit the shielding member 51 to the first position, and the limiting portion 711 engages with the other groove 731 to generate a second limiting force to limit the shielding member 51 to the second position. The matching piece 73 is used to cooperate with the limiting piece 71 to limit the shielding member 51 to remain in the first position and the second position. The opening shape of the groove 731 is an arc, so as to cooperate with the spherical limiting portion 711. The limiting portion 711 engages with the groove 731 close to the loading hole 11 to generate a second limiting force, thereby limiting the shielding member 51 to remain in the second position. The limiting portion 711 engages with the groove 731 away from the loading hole 11 to generate a first limiting force, thereby limiting the shielding member 51 to remain in the first position.

[0064] When the stopper 71 is engaged with the groove 731 near the loading hole 11, the stopper 711 protrudes from the mounting portion 713. When the shielding member 51 rotates to make the groove 731 near the loading hole 11 leave the stopper 71 engaged therewith, the shielding member 51 compresses the stopper 711, and the elastic portion 715 is squeezed to drive the stopper 711 to shrink toward the inside of the mounting portion 713. When the shielding member 51 rotates to separate the groove 731 near the loading hole 11 from the stopper 711, and the stopper 711 is not yet engaged with the groove 731 far from the loading hole 11, the elastic portion 715 and the stopper 711 are squeezed by the shielding member 51 to the maximum extent, and at this time, the limiting force between the stopper 71 and the matching member 73 is the maximum. When the shielding member 51 continues to rotate, the limiting portion 711 engages with the groove 731 away from the loading hole 11 , and the elastic portion 715 drives the limiting portion 711 to extend toward the groove 731 , so that the limiting portion 711 engages with the groove 731 .

[0065] In other embodiments, the limiter 71 may be a retractable structure disposed on the toggle member 53, and the matching member 73 may be a groove 731 disposed on the housing 10. The limiter 71 cooperates with the two matching members 73 to enable the shielding member 51 to be located at the first position and the second position.

[0066] See also Figure 7 and Figure 8 In some embodiments, the limiting member 71 and the matching member 73 are spaced apart and interact with each other through magnetic cooperation to limit the shielding member 51 to be in the first position or the second position. The shielding member 51 of the present application can rotate relative to the housing 10 and the cover 30, and the limiting portion 711 and the matching member 73 are rotated to make the shielding member 51 in the first position and the second position. The limiting member 71 and the matching member 73 form a first limiting force to limit the shielding member 51 to be in the first position through the attraction or repulsion between the magnetic poles, and form a second limiting force to limit the shielding member 51 to be in the second position.

[0067] See also Figure 7 In some embodiments, the limiting member 71 is a first magnetic member 717, the matching member 73 is a second magnetic member 733, the first magnetic member 717 and the second magnetic member 733 repel each other to generate a first limiting force and a second limiting force, the first position and the second position are located on opposite sides of the first magnetic member 717, and when the shielding member 51 is in the middle position between the first position and the second position, the first magnetic member 717 is opposite to the second magnetic member 733. At this time, the repulsive force between the first magnetic member 717 and the second magnetic member 733 is the largest, and the first magnetic member 717 has a tendency to move away from the second magnetic member 733.

[0068] Specifically, the first magnetic member 717 may be a magnet or other magnetic structure, and the second magnetic member 733 may be a magnet or other magnetic object. The first magnetic member 717 and the second magnetic member 733 may be the same object or different objects. The first magnetic member 717 and the second magnetic member 733 of the embodiment of the present application are both magnets. The first magnetic member 717 and the second magnetic member 733 may be cylindrical or prismatic structures. The first magnetic member 717 is installed in the first receiving groove 13 of the shell 10, and the height direction of the first magnetic member 717 is parallel to the height direction H of the aerosol generating device 100. The second magnetic member 733 is installed in the groove of the side wall of the shielding member 51, and the height direction of the second magnetic member 733 is parallel to the height direction H of the aerosol generating device 100.

[0069] The relative poles of the first magnetic member 717 are respectively located at the upper and lower ends, and the relative poles of the second magnetic member 733 are also respectively located at the upper and lower ends. Preferably, the first magnetic member 717 and the second magnetic member 733 have the same height, so that the magnetic poles at the upper end of the first magnetic member 717 and the magnetic poles at the upper end of the second magnetic member 733 are located at the same horizontal plane perpendicular to the height direction H of the aerosol generating device 100, and the magnetic poles at the lower end of the first magnetic member 717 and the magnetic poles at the lower end of the second magnetic member 733 are located at the same horizontal plane perpendicular to the height direction H of the aerosol generating device 100, so that the repulsive force generated between the first magnetic member 717 and the second magnetic member 733 is perpendicular to the height direction H of the aerosol generating device 100.

[0070] In one embodiment, the upper end of the first magnetic member 717 is an N pole, and the lower end of the first magnetic member 717 is an S pole. In this case, the upper end of the second magnetic member 733 is an N pole, and the lower end of the second magnetic member 733 is an S pole. In another embodiment, the upper end of the first magnetic member 717 is an S pole, and the lower end of the first magnetic member 717 is an N pole. In this case, the upper end of the second magnetic member 733 is an S pole, and the lower end of the second magnetic member 733 is an N pole.

[0071] At this time, the first limiting force is the repulsive force between the first magnetic member 717 and the second magnetic member 733, and the second limiting force is the repulsive force between the first magnetic member 717 and the second magnetic member 733. In the process of the shielding member 51 rotating from the first position to the second position, the distance between the limit member 71 and the matching member 73 is from far to near, and the horizontal repulsive force between the limit member 71 and the matching member 73 is getting larger and larger. When the distance between the limit member 71 and the matching member 73 is the closest, the horizontal repulsive force between the limit member 71 and the matching member 73 reaches the maximum. As the distance between the limit member 71 and the matching member 73 is from near to far, the horizontal repulsive force between the limit member 71 and the matching member 73 gradually decreases.

[0072] When the shielding member 51 is in the first position, due to the repulsive force between the stopper 71 and the matching member 73, the shielding member 51 can be stably in the first position covering the loading hole 11. An external force opposite to the repulsive force is applied to the shielding member 51 to rotate the shielding member 51 from the first position to the second position. When the shielding member 51 passes the position where the repulsive force is the largest, the repulsive force between the stopper 71 and the matching member 73 can enable the shielding member 51 to quickly reach the second position and stably stay in the second position.

[0073] See also Figure 8 In some embodiments, the limiting component 70 includes two limiting members 71, the limiting member 71 is a first magnetic member 717, and the matching member 73 is a second magnetic member 733. When the shielding member 51 is in the first position, one first magnetic member 717 is attracted to the second magnetic member 733, and when the shielding member 51 is in the second position, the other first magnetic member 717 is attracted to the second magnetic member 733.

[0074] Specifically, the two first magnetic members 717 are respectively installed in the receiving grooves of the housing 10, and the height directions of the two first magnetic members 717 are parallel to the height direction H of the aerosol generating device 100. The second magnetic member 733 is installed in the groove 731 of the side wall of the shielding member 51, and the height direction of the second magnetic member 733 is parallel to the height direction H of the aerosol generating device 100.

[0075] The two first magnetic members 717 are respectively arranged near the first position and the second position of the shielding member 51. When the shielding member 51 is in the first position, the first magnetic member 717 near the first position and the second magnetic member 733 attract each other, so that the shielding member 51 is firmly in the first position. When the shielding member 51 is in the second position, the first magnetic member 717 near the second position and the second magnetic member 733 attract each other, so that the shielding member 51 is firmly in the second position.

[0076] The first magnetic member 717 and the second magnetic member 733 have the same height. In one embodiment, the upper end of the first magnetic member 717 near the first position is an N pole, and the lower end is an S pole. The upper end of the first magnetic member 717 near the second position is an N pole, and the lower end is an S pole. At this time, the upper end of the second magnetic member 733 is an S pole, and the lower end of the second magnetic member 733 is an N pole. In another embodiment, the upper end of the first magnetic member 717 near the first position is an S pole, and the lower end is an N pole. The upper end of the first magnetic member 717 near the second position is an S pole, and the lower end is an N pole. At this time, the upper end of the second magnetic member 733 is an N pole, and the lower end of the second magnetic member 733 is an S pole.

[0077] At this time, the first limiting force is the suction force between the first magnetic member 717 and the second magnetic member 733 close to the loading hole 11, and the second limiting force is the suction force between the first magnetic member 717 and the second magnetic member 733 far from the loading hole 11. In the process of the shielding member 51 rotating from the first position to the second position, the distance between the first magnetic member 717 and the second magnetic member 733 close to the loading hole 11 is from near to far, and the horizontal suction force between the first magnetic member 717 and the second magnetic member 733 close to the loading hole 11 is getting smaller and smaller. When the distance between the second magnetic member 733 and the two first magnetic members 717 is equal, the horizontal suction force between the second magnetic member 733 and the two first magnetic members 717 reaches the minimum. As the distance between the second magnetic member 733 and the first magnetic member 717 far from the loading hole 11 is from far to near, the horizontal suction force between the first magnetic member 717 and the second magnetic member 733 far from the loading hole 11 gradually increases, so as to firmly adsorb the shielding member 51 to the second position.

[0078] When the shielding member 51 is in the first position, due to the suction between the stopper 71 and the matching member 73 near the first position, the shielding member 51 can be stably in the first position covering the loading hole 11. An external force opposite to the first limiting force is applied to the shielding member 51 to rotate the shielding member 51 from the first position to the second position. When the shielding member 51 passes the position with the smallest suction force, the suction between the stopper 71 and the matching member 73 near the second position can enable the shielding member 51 to quickly reach the second position and stably stay in the second position.

[0079] In the aerosol generating device 100 of the present application, the shielding component 50 is located between the housing 10 and the cover 30, so that the integrity and aesthetics of the aerosol generating device 100 are better. In addition, the aerosol generating device 100 is provided with a stopper 71 and a matching member 73, and the stopper 71 and the matching member 73 cooperate with each other. When the loading hole 11 needs to be blocked, the shielding component 51 can be stably in the first position, and when the loading hole 11 needs to be opened, the shielding component 51 can be stably in the second position, thereby preventing the shielding component 51 from shaking between the housing 10 and the cover 30.
