[0001] Priority information

[0002] This application claims priority and benefits of the patent application with patent application number 202311095353.X filed with the State Intellectual Property Office of China on August 28, 2023, and the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Art

[0004] An aerosol generating device is a small device that can use heat not burn (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 production of harmful substances. As people pay more and more attention to their health, aerosol generating devices have gradually become people's first choice.

[0005] To prevent foreign matter from entering aerosol generating devices and generating harmful substances during heating that could harm human health, aerosol generating devices are typically equipped with a shielding assembly. However, currently available shielding assemblies are typically located on the outside of the aerosol generating device, affecting its integrity and aesthetics.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide an aerosol generating device, which is at least used to solve the problem that the shielding component is arranged outside the aerosol generating device, affecting the integrity and aesthetics of the aerosol generating device.

[0008] An aerosol generating device according to an embodiment of the present application comprises a housing, a cover, a shielding assembly, and a limiting assembly. The housing is provided with a loading hole for loading an aerosol-generating product. The cover is mounted on the housing and defines a through-hole corresponding to the loading hole. The shielding assembly is disposed between the housing and the cover and includes a shielding member that is movable relative to the housing and the cover under the action of an external force. The limiting assembly includes a limiting member and a mating member, one of which is disposed on the shielding assembly and the other on the housing or the cover. The limiting member and the mating member intersect in the height direction of the aerosol generating device. When the shielding member is in a first position covering the loading hole, the limiting member interacts with the mating member to restrict the shielding member to the first position. When the shielding member is in a second position opening the loading hole, the limiting member interacts with the mating member to restrict the shielding member to the second position.

[0009] 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.

[0010] In certain embodiments, the toggle member is columnar and rotatably connected to the cover and / or the housing, and the shielding member is disposed at one end of the toggle member along the height direction.

[0011] In some embodiments, the matching member is disposed on a side wall of the toggle member, and the limiting member is disposed on the housing or the cover.

[0012] In certain 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.

[0013] 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.

[0014] In some embodiments, the position-limiting member further includes a mounting portion and an elastic portion. The elastic portion is mounted on the mounting portion, one end of the elastic portion is connected to the mounting portion, and the other end of the elastic portion is connected to the position-limiting member. When the elastic portion is in a natural state, the position-limiting member protrudes relative to the mounting portion toward the mating member.

[0015] In certain embodiments, the limiting member and the matching member are spaced apart and interact with each other through magnetic cooperation to limit the shielding member to be in the first position or the second position.

[0016] In some embodiments, the limiting member is a first magnetic member, the matching member is a second magnetic member, the first magnetic member and the second magnetic member repel each other, the first position and the second position are located on opposite sides of the first magnetic member, and when the shielding member is in an intermediate position between the first position and the second position, the first magnetic member is opposite to the second magnetic member.

[0017] In some embodiments, the limiting assembly includes two limiting members, the limiting member is a first magnetic member, and the matching member is a second magnetic member. When the shielding member is in the first position, one of the first magnetic members is attracted to the second magnetic member, and when the shielding member is in the second position, the other of the first magnetic members is attracted to the second magnetic member.

[0018] In the aerosol generating device of the embodiment of the present application, the shielding assembly is located between the housing and the cover, thereby improving the integrity and aesthetics of the aerosol generating device. Furthermore, the aerosol generating device is provided with a stopper and a mating member, which cooperate with each other. When the loading hole needs to be blocked, the shielding member can be stably positioned in the first position, and when the loading hole needs to be opened, the shielding member can be stably positioned in the second position, thereby preventing the shielding member from dangling between the housing and the cover.

[0037] To prevent foreign matter from entering the aerosol generating device and generating harmful substances during heating that could affect human health, aerosol generating devices are typically equipped with a shielding assembly. However, currently available shielding assemblies are typically located outside the aerosol generating device, affecting its integrity and aesthetics. To address this issue, an embodiment of the present application provides an aerosol generating device 100 (shown in FIG1 ).

[0038] Referring to Figures 1 and 2, the aerosol generating device 100 according to an embodiment of the present application includes a housing 10, a cover 30, a shielding assembly 50, and a limiting assembly 70. The housing 10 is provided with a loading hole 11 for loading an aerosol generating product. The cover 30 is mounted on the housing 10 and is provided with a through hole 31 corresponding to the loading hole 11. The shielding assembly 50 is disposed between the housing 10 and the cover 30. The shielding assembly 50 includes a shielding member 51, which is capable of moving relative to the housing 10 and the cover 30 under the action of an external force. The limiting assembly 70 includes a limiting member 71 and a mating member 73. One of the limiting member 71 and the mating member 73 is disposed on the shielding assembly 50, and the other is disposed on the housing 10 or the cover 30. The limiting member 71 and the mating member 73 intersect in the height direction H of the aerosol generating device 100. When the shielding member 51 is in the first position (as shown in Figure 3) covering the loading hole 11, the limiting member 71 interacts with the matching member 73 to limit the shielding member 51 to the first position. When the shielding member 51 is in the second position (as shown in Figure 4) opening the loading hole 11, the limiting member 71 interacts with the matching member 73 to limit the shielding member 51 to the second position.

[0039] Specifically, the aerosol-generating device 100 is a structure capable of generating aerosols by applying resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration to an aerosol-generating article. For example, the aerosol-generating device 100 can use microwave radiation to heat the aerosol-generating article to generate an aerosol. Aerosols can be visible or invisible and can include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol-generating article is a product loaded with an aerosol-generating substrate. The housing of the aerosol-generating article is not limited to a paper housing, a plastic housing, or a metal housing, and the aerosol-generating substrate is loaded within the housing to form the aerosol-generating article. The aerosol-generating substrate is a plant leaf product that has been processed and heated to generate an aerosol. The aerosol-generating substrate can be in a fully solid or semi-solid state. If the aerosol-generating substrate is fully solid, it can be produced using processes such as rolling, slurrying, die casting, and extrusion. 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.

[0040] The shell 10 is a structure for accommodating other components. The shell 10 in the present application is used to accommodate the heating element, circuit board, control element and power supply unit of the aerosol generating device 100. The material of the shell 10 can 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, the shell 10 is not easily damaged, and the service life is long; when the material of the shell 10 is plastic, the weight of the shell 10 is light, easy to carry, and the cost of the shell 10 is low; when the material of the shell 10 is ceramic, the hardness of the shell 10 is high, not easy to deform, and the corrosion resistance of the shell 10 is good, and the service life is long. The cross-section of the shell 10 can be, but is not limited to, circular, elliptical or rectangular.

[0041] The loading hole 11 is a space structure for loading other components. To inhale an aerosol, the aerosol-generating product must first be loaded into the loading hole 11. The control element in the inner cavity of the housing 10 controls the heating element to heat the aerosol-generating product, generating an aerosol for the user to inhale. Once the aerosol-generating product has been completely inhaled, it must be removed from the loading hole 11 to facilitate loading a new aerosol-generating product into the loading hole 11 for the next inhalation. The shape of the loading hole 11 can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal.

[0042] 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 is connected to 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, it is not easy to be damaged, and the service life is long; when the material of the cover 30 is plastic, the weight of the cover 30 is light, it is 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, it is not easy to deform, and it has good corrosion resistance and a long service life. The material of the cover 30 can be the same as or different from the material of the shell 10. The cross-sectional shape of the cover 30 is basically the same as the cross-sectional shape of the shell 10, so that the cover 30 and the shell 10 are firmly connected.

[0043] Through-hole 31 is used to allow the aerosol generated by the heated aerosol-generating product in loading hole 11 to flow out of through-hole 31 for inhalation by the user. The shape of through-hole 31 may be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal. The shape of through-hole 31 may be the same as or different from that of loading hole 11, and the cross-sectional area of ​​through-hole 31 may be the same as or different from that of loading hole 11, as long as through-hole 31 is in communication with loading hole 11.

[0044] 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 an 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, a circle, an ellipse, a quadrilateral or other polygons. The cross-sectional area of ​​the shielding member 51 can be 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 can be larger than the cross-sectional area of ​​the loading hole 11 and the through hole 31. When it is necessary to cover the loading hole 11, the shielding member 51 is located between the loading hole 11 and the through hole 31. The shielding member 51 is used to separate the loading hole 11 and the through hole 31 to prevent external substances from entering the loading hole 11 from the through hole 31.

[0045] The limiting assembly 70 is a structure for limiting the movement of the shielding assembly 50. The limiting member 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 limiting member 71 is provided on the housing 10, and the matching member 73 is provided on the shielding assembly 50. In another embodiment, the limiting member 71 is provided on the cover 30, and the matching member 73 is provided on the shielding assembly 50. In still another embodiment, the limiting member 71 is provided on the shielding assembly 50, and the matching member 73 is provided on the housing 10. In yet another embodiment, the limiting member 71 is provided on the shielding assembly 50, and the matching member 73 is provided on the cover 30. In the embodiment of the present application, the limiting member 71 is provided on the housing 10, and the matching member 73 is provided on the shielding assembly 50.

[0046] Referring to Figures 3 and 4 , when the shielding member 51 is in the first position, covering the loading hole 11, the limiting member 71 cooperates with the mating member 73 to generate a first limiting force. The first limiting force is used to limit the shielding member 51 from moving toward the second position, allowing the shielding member 51 to stably remain in the first position to cover the loading hole 11. When the shielding member 51 is in the second position, opening the loading hole 11, the limiting member 71 cooperates with the mating member 73 to generate a second limiting force. The second limiting force is used to limit the shielding member 51 from moving toward the first position, allowing the shielding member 51 to stably remain in the second position to open the loading hole 11, thereby facilitating the user's inhalation of the aerosol.

[0047] The intersection of the limiter 71 and the mating 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, the height of at least a portion of the structure of the limiter 71 is the same as the height of at least a portion of the structure of the mating member 73. In one embodiment, the height of the portion of the structure of the limiter 71 is the same as the height of the portion of the structure of the mating member 73. In this case, the installation of the limiter 71 and the mating member 73 is relatively simple, as it is sufficient that the portion of the structure of the limiter 71 and the mating member 73 have the same height. In another embodiment, the limiter 71 and the mating member 73 have the same height, that is, the limiter 71 and the mating member 73 are located at the same height. When the limiter 71 and the mating member 73 are located at the same height, the first limiting force and the second limiting force generated between the limiter 71 and the mating member 73 are forces acting perpendicular to the height direction H of the aerosol generating device 100. At this time, if 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 to move the shielding member 51 to the second position. If 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 to move the shielding member 51 to the second position. The opening and closing of the loading hole are simple and easy to control.

[0048] In the aerosol generating device 100 of the embodiment of the present application, the shielding assembly 50 is located between the housing 10 and the cover 30, thereby enhancing the integrity and aesthetics of the aerosol generating device 100. Furthermore, the aerosol generating device 100 is provided with a stopper 71 and a mating member 73, which cooperate with each other. When the loading hole 11 needs to be blocked, the shielding member 51 can be stably positioned in the first position. When the loading hole 11 needs to be opened, the shielding member 51 can be stably positioned in the second position, thereby preventing the shielding member 51 from dangling between the housing 10 and the cover 30.

[0049] The aerosol generating device 100 will be further described below with reference to the accompanying drawings.

[0050] Please refer to 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. Under the action of external force, 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.

[0051] 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 or 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 can be detachably or non-detachably connected to the shielding member 51. The detachable connection method includes but is not limited to threaded connection, screw connection or snap connection. The non-detachable connection method includes but is not limited to welding, gluing or interference fit.

[0052] 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. In the present application, the column portion 533 is used to drive the shielding member 51 to rotate so as to switch the shielding member 51 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 to cause the toggle member 53 to drive the shielding member 51 to switch between the first position and the second position.

[0053] In one embodiment, the toggle portion 531 protrudes from a perforation in 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 operate. The user can apply external force to the toggle portion 531 protruding from the side wall of the housing 10, thereby moving the shielding member 51. In another embodiment, the toggle portion 531 corresponds to a perforation in the side wall of the housing 10. In this case, the overall structure of the aerosol generating device 100 is smaller, easier to carry, and more aesthetically pleasing. The user can insert an object such as a thimble through the perforation to control the toggle portion 531.

[0054] Referring to Figures 2 to 4 , in certain embodiments, the toggle member 53 is cylindrical and rotatably connected to the cover 30 and / or housing 10. 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 cylindrical structure, allowing the toggle member 53 to rotate relative to the cover 30 or housing 10. The column portion 533 extends parallel to the height direction H of the aerosol generating device 100. The shielding member 51 of the present application is disposed at the top of the column portion 533. When a user applies force to the toggle member 531, the column portion 533 is subjected to the 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.

[0055] Referring to Figures 2 to 4 , the shielding assembly 50 further 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 . The connector 55 is configured to allow the column 533 to rotate relative to the housing 10 and the cover 30 . Preferably, the connector 55 is cylindrical in shape, 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 mounted within the second receiving groove 15 of the housing 10 . The connection between the connector 55 and the housing 10 may be, but is not limited to, threaded, snap-fit, welded, or glued.

[0056] 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. In this case, when a user applies an external force to the toggle portion 531, the connecting member 55 rotates to drive the column portion 533 to rotate, thereby driving the column portion 533 to switch the shielding member 51 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. In this case, when a user applies an external force to the toggle portion 531, the toggle portion 531 drives the column portion 533 to rotate relative to the connecting member 55, thereby driving the shielding member 51 to switch between the first position and the second position.

[0057] 2 and 4 , in some embodiments, when the shielding member 51 switches from the first position to the second position, the limiting force generated by the limiting member 71 and the matching member 73 increases from small to large and then to small.

[0058] Specifically, when the shielding member 51 switches from the first position to the second position, the restraining force between the stopper 71 and the mating member 73 is relatively small in the first position. When the shielding member 51 is in a position intermediate between the first and second positions, the restraining force between the stopper 71 and the mating member 73 is at its maximum. As the shielding member 51 reaches the second position, the restraining force between the stopper 71 and the mating member 73 gradually decreases. As the user moves the shielding member 51, they can feel the restraining force increase and then decrease, thereby determining whether the shielding member 51 has been moved into position.

[0059] Referring to Figures 5 and 6 , in certain embodiments, the engaging member 73 is disposed on a side wall of the toggle member 53, and the retaining member 71 is disposed on the housing 10 or the cover 30. Specifically, the engaging member 73 is disposed on a side wall of the column portion 533 opposite the retaining member 71. The retaining member 71 can be disposed on either the housing 10 or the cover 10, with the retaining member 71 facing the engaging member 73.

[0060] Referring to Figures 5 and 6 , in certain embodiments, the stopper 71 and the mating member 73 engage and cooperate to restrict the shielding member 51 to either the first or second position. The stopper 71 and the mating member 73 cooperate to generate a first restricting force to restrict the shielding member 51 to the first position, and the stopper 71 and the mating member 73 cooperate to generate a second restricting force to restrict the shielding member 51 to the second position. In this embodiment of the present application, the stopper 71 and the mating member 73 interfere with each other to generate the first and second restricting forces.

[0061] Continuing to refer to Figures 5 and 6, in some embodiments, the stopper 71 is a retractable structure comprising a protruding stopper 711, a mounting portion 713, and an elastic portion 715. The elastic portion 715 is mounted on the mounting portion 713, with one end of the elastic portion 715 connected to the mounting portion 713 and the other end of the elastic portion 715 connected to the stopper 711. When the elastic portion 715 is in its natural position, the stopper 711 protrudes relative to the mounting portion 713 toward the mating member 73.

[0062] Specifically, 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 match each other so that the shielding member 51 is maintained at the first position and the second position.

[0063] The stopper 711 is a structure used to cooperate with the mating member 73 to restrict the shielding member 51 from being in the first position and the second position. Preferably, the stopper 711 is a spherical structure to facilitate the rotation of the shielding member 51 and to mate with the stopper 711. The stopper 711 can be a hollow spherical structure or a solid spherical structure. If the stopper 711 is a hollow spherical structure, the stopper 711 is lighter and can save material. If the stopper 711 is a solid spherical structure, the structural strength of the stopper 711 is higher and the service life is longer.

[0064] 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. In this case, 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.

[0065] The elastic portion 715 can drive the movement of other components connected to it by its own extension and contraction. The elastic portion 715 of the present application is used to drive the movement of the limit member 71 connected to it. The elastic portion 715 is installed inside the mounting portion 713. The elastic portion 715 is detachably or non-detachably connected to the mounting portion 713 and the limit member 711. Among them, detachable installation methods include but are not limited to threaded connection or snap connection. Non-detachable installation methods include but are not limited to welding or gluing. The elastic portion 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 or a conical coil spring. When the elastic portion 715 is a coil spring, the elastic portion 715 is small in size and light in weight, making it easy to disassemble and assemble. When the elastic portion 715 is a leaf spring, the elastic portion 715 has a simpler structure, is more convenient to process, and has a stronger load-bearing capacity.

[0066] Continuing with Figures 5 and 6 , in certain embodiments, the retaining assembly 70 includes two mating members 73. The mating members 73 are grooves 731 formed on the sidewalls of the toggle portion 531 of the toggle member 53. The retaining member 711 engages with one of the grooves 731 to generate a first restraining force, thereby restraining the shielding member 51 in the first position. The retaining member 711 engages with the other groove 731 to generate a second restraining force, thereby restraining the shielding member 51 in the second position. The mating members 73 are configured to engage with the retaining member 71 to restrain the shielding member 51 between the first and second positions. The grooves 731 are arc-shaped to facilitate engagement with the spherical retaining member 711. The retaining member 711 engages with the groove 731 proximal to the loading hole 11 to generate the second restraining force, thereby restraining the shielding member 51 in the second position. The retaining member 711 engages with the groove 731 distal to the loading hole 11 to generate the first restraining force, thereby restraining the shielding member 51 in the first position.

[0067] When the limiting member 71 is engaged with the groove 731 near the loading hole 11, the limiting portion 711 protrudes from the mounting portion 713. As the shield 51 rotates to separate the groove 731 near the loading hole 11 from the limiting member 71, the shield 51 compresses the limiting portion 711, squeezing the elastic portion 715 and causing the limiting portion 711 to retract toward the interior of the mounting portion 713. When the shield 51 rotates until the groove 731 near the loading hole 11 is separated from the limiting portion 711, and the limiting portion 711 has not yet engaged with the groove 731 away from the loading hole 11, the elastic portion 715 and the limiting portion 711 are squeezed and compressed to the maximum extent by the shield 51, and the limiting force between the limiting member 71 and the mating member 73 is at its 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 .

[0068] In other embodiments, the limiting member 71 may be a retractable structure provided on the toggle member 53, and the matching member 73 may be a groove 731 provided on the housing 10. The limiting member 71 cooperates with the two matching members 73 to position the shielding member 51 at the first position and the second position.

[0069] Referring to Figures 7 and 8 , in certain embodiments, the limiting member 71 and the mating member 73 are spaced apart and interact magnetically to constrain the shielding member 51 to either the first or second position. The shielding member 51 of the present application is capable of rotating relative to the housing 10 and the cover 30. The limiting portion 711 and the mating member 73 rotate to maintain the shielding member 51 in the first and second positions. The limiting member 71 and the mating member 73 generate a first limiting force to constrain the shielding member 51 to the first position, and a second limiting force to constrain the shielding member 51 to the second position, through the attraction or repulsion between the magnetic poles.

[0070] Referring to FIG. 7 , in certain embodiments, the limiting member 71 is a first magnetic member 717, and the engaging 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. When the shielding member 51 is in an intermediate position between the first and second positions, the first magnetic member 717 and the second magnetic member 733 are opposite each other. At this point, the repulsive force between the first magnetic member 717 and the second magnetic member 733 is at its maximum, and the first magnetic member 717 tends to move away from the second magnetic member 733.

[0071] 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 in 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.

[0072] The first magnetic member 717 has its two opposing poles located at the upper and lower ends, respectively, and the second magnetic member 733 also has its two opposing poles located at the upper and lower ends, respectively. Preferably, the first magnetic member 717 and the second magnetic member 733 are at the same height, so that the upper magnetic pole of the first magnetic member 717 and the upper magnetic pole of the second magnetic member 733 are located in the same horizontal plane perpendicular to the height direction H of the aerosol generating device 100, and the lower magnetic pole of the first magnetic member 717 and the lower magnetic pole of the second magnetic member 733 are located in the same horizontal plane perpendicular to the height direction H of the aerosol generating device 100. Thus, 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.

[0073] 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.

[0074] 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. During the process of rotating the shielding member 51 from the first position to the second position, the distance between the limiting member 71 and the matching member 73 decreases, and the horizontal repulsive force between the limiting member 71 and the matching member 73 increases. When the distance between the limiting member 71 and the matching member 73 is the shortest, the horizontal repulsive force between the limiting member 71 and the matching member 73 reaches its maximum. As the distance between the limiting member 71 and the matching member 73 decreases, the horizontal repulsive force between the limiting member 71 and the matching member 73 gradually decreases.

[0075] When the shield 51 is in the first position, the repulsive force between the stopper 71 and the mating member 73 allows the shield 51 to remain securely in the first position, covering the loading hole 11. An external force opposite to the repulsive force is applied to the shield 51, causing it to rotate from the first position to the second position. Once the shield 51 passes the position where the repulsive force is greatest, the repulsive force between the stopper 71 and the mating member 73 allows the shield 51 to quickly reach the second position, where it remains securely.

[0076] Please refer to Figure 8. In some embodiments, the limiting assembly 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. When the shielding member 51 is in the second position, the other first magnetic member 717 is attracted to the second magnetic member 733.

[0077] 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.

[0078] The two first magnetic members 717 are respectively disposed 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, thereby firmly maintaining the shielding member 51 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, thereby firmly maintaining the shielding member 51 in the second position.

[0079] 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 the north pole, and the lower end is the south pole. The upper end of the first magnetic member 717 near the second position is the north pole, and the lower end is the south pole. In this case, the upper end of the second magnetic member 733 is the south pole, and the lower end of the second magnetic member 733 is the north pole. In another embodiment, the upper end of the first magnetic member 717 near the first position is the south pole, and the lower end is the north pole. The upper end of the first magnetic member 717 near the second position is the south pole, and the lower end is the north pole. In this case, the upper end of the second magnetic member 733 is the north pole, and the lower end of the second magnetic member 733 is the south pole.

[0080] At this time, the first limiting force is the suction force between the first magnetic member 717 and the second magnetic member 733 near 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 away from the loading hole 11. During the process of rotating the shielding member 51 from the first position to the second position, the distance between the first magnetic member 717 and the second magnetic member 733 near the loading hole 11 gradually increases, and the horizontal suction force between the first magnetic member 717 and the second magnetic member 733 near the loading hole 11 gradually decreases. 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 its minimum. As the distance between the second magnetic member 733 and the first magnetic member 717 away from the loading hole 11 gradually decreases, the horizontal suction force between the first magnetic member 717 and the second magnetic member 733 away from the loading hole 11 gradually increases, thereby firmly adsorbing the shielding member 51 to the second position.

[0081] When the shielding member 51 is in the first position, the suction force between the stopper 71 near the first position and the mating member 73 allows the shielding member 51 to remain securely in the first position, covering the loading hole 11. An external force opposite to the first restraining force is applied to the shielding member 51, causing it to rotate from the first position toward the second position. When the shielding member 51 passes the position where the suction force is minimal, the suction force between the stopper 71 near the second position and the mating member 73 allows the shielding member 51 to quickly reach the second position, where it remains securely.

[0082] In the aerosol generating device 100 of the present embodiment, the shielding assembly 50 is located between the housing 10 and the cover 30, enhancing the integrity and aesthetics of the aerosol generating device 100. Furthermore, the aerosol generating device 100 includes a stopper 71 and a mating member 73, which cooperate with each other. When the loading hole 11 needs to be blocked, the shielding member 51 can be stably positioned in the first position. When the loading hole 11 needs to be opened, the shielding member 51 can be stably positioned in the second position, thereby preventing the shielding member 51 from dangling between the housing 10 and the cover 30.
