Description

Technical Field

[0001] This invention relates to the field of atomization technology, and more particularly to a charging device and an aerosol generation system. Background Technology

[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to act on an aerosol-generating matrix and produce aerosols. In related technologies, users typically use a charging device to charge or store the aerosol generator; for example, when the aerosol generator's battery is low, the user can store it in the charging port of the charging device to recharge. To prevent external substances from falling into the charging port and affecting the cleanliness of the charging device's interior or damaging other internal components, the charging device usually has a cover for opening or closing the charging port. However, currently, when the cover is opened or closed, the internal components of the charging device are easily exposed. Utility Model Content

[0003] This invention provides a charging device and an aerosol generation system.

[0004] This application provides a charging device. The charging device includes a housing, a cover, and a magnetic assembly. The housing has a loading hole. The cover is slidably disposed on the housing to switch between a first position and a second position on the housing. In the first position, the cover opens the loading hole; in the second position, the cover closes the loading hole. The magnetic assembly includes a first magnetic element, a second magnetic element, a third magnetic element, and a fourth magnetic element. The first and second magnetic elements are spaced apart along the length of the cover, and the third and fourth magnetic elements are spaced apart along the length of the housing. The first, second, third, and fourth magnetic elements cooperate to maintain the cover in either the first or second position.

[0005] In some embodiments, the housing has a guide member on the side facing the cover, and the cover has a guide groove on the side facing the housing. The guide member extends into the guide groove, and the cover slides in the guide groove via the guide member. On a projection plane perpendicular to the height direction, the projection of the guide member lies within the projection of the cover.

[0006] In some embodiments, the guide groove includes a first sub-groove and a second sub-groove connected sequentially, the first sub-groove being closer to the side of the cover facing the housing, and the guide member includes a body portion and a snap-fit ​​portion. The body portion is at least partially accommodated in the first sub-groove and the second sub-groove. The snap-fit ​​portion is disposed at one end of the body portion near the cover, and the snap-fit ​​portion is accommodated in the second sub-groove.

[0007] In some embodiments, the magnetic poles of the first and second magnetic elements facing the housing are opposite, and the charging device further includes a Hall sensor. The Hall sensor is used to respond to the first or second magnetic element to detect the position of the cover.

[0008] In some embodiments, in the first position, the Hall sensor is opposite the first magnetic element in the height direction.

[0009] In some embodiments, the third and fourth magnetic elements are oriented in opposite directions toward the magnetic poles of the first or second magnetic element.

[0010] In some embodiments, when the cover is in the first position, the second magnetic element and the third magnetic element are opposite to each other in the height direction of the charging device, and the magnetic pole of the first magnetic element facing the third magnetic element is opposite to the magnetic pole of the third magnetic element facing the first magnetic element.

[0011] In some embodiments, when the cover is in the second position, the first magnetic element and the fourth magnetic element are opposite to each other in the height direction, and the magnetic pole of the second magnetic element facing the fourth magnetic element is opposite to the magnetic pole of the fourth magnetic element facing the fourth magnetic element.

[0012] In some embodiments, there are multiple first magnetic elements, second magnetic elements, third magnetic elements, and fourth magnetic elements, the length direction intersects the width direction, and multiple first magnetic elements and multiple second magnetic elements are respectively located on opposite sides of the guide groove in the width direction; and / or, multiple third magnetic elements and multiple fourth magnetic elements are located on opposite sides of the housing in the width direction.

[0013] In some embodiments, the charging device further includes a control element. The control element is capable of acquiring the position of the cover detected by the Hall sensor to instruct the behavior of the charging device.

[0032] An aerosol generating device is a small device that uses a heat-non-combustible technology to act on an aerosol generating matrix 200 to generate aerosols. In related technologies, users typically use a charging device to charge or store the aerosol generating device; for example, when the aerosol generating device's battery is low, the user can store it in the charging port of the charging device to charge it. To prevent external substances from falling into the charging port and affecting the cleanliness of the charging device's interior or damaging other internal components, the charging device usually has a cover for opening or closing the charging port. However, currently, when the cover is opened or closed, the internal parts of the charging device are easily exposed. To solve this problem, please refer to... Figure 1 This application provides a charging device 100 and an aerosol generation system 1000.

[0033] Please see Figure 1 The aerosol generation system 1000 of this application includes a charging device 100 and an aerosol generation device 300. The aerosol generation device 300 is detachably housed in the loading hole 11 of the charging device 100. The aerosol generation device 300 is provided with a receiving cavity 301, which is configured to receive the aerosol generation matrix 200.

[0034] The aerosol generating device 300 is a structure in the aerosol generating system 1000 capable of generating aerosols by heating the aerosol generating matrix 200. Specifically, the aerosol generating matrix 200 is a processed product that can generate aerosols after being heated. The aerosol generating matrix 200 can be in liquid, solid, or semi-solid form. For example, when the aerosol generating matrix 200 is solid, it can be in sheet or columnar form. The aerosol generating matrix 200 can be prepared using processes such as rolling, slurry preparation, die casting, or extrusion. The aerosol can be visible or invisible and may 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.

[0035] The charging device 100 is a structure in the aerosol generation system 1000 capable of charging at least the aerosol generation device 300. For example, when the aerosol generation device 300 has insufficient power, the user can place the aerosol generation device 300 into the loading hole 11. In this case, the aerosol generation device 300 is housed in the loading hole 11, and the charging device 100 is electrically connected to the aerosol generation device 300, thereby enabling the charging device 100 to charge the aerosol generation device 300.

[0036] Since the aerosol generation system 1000 in this embodiment includes a charging device 100, it is understood that the aerosol generation system 1000 has at least the same beneficial effects as the charging device 100. Therefore, for the beneficial effects of the aerosol generation system 1000, please refer to the beneficial effects of the charging device 100 described below.

[0037] Please see Figures 2 to 5This application provides a charging device 100. The charging device 100 includes a housing 10, a cover 20, and a magnetic assembly 30. The housing 10 is provided with a loading hole 11. The cover 20 is slidably disposed on the housing 10 to switch between a first position and a second position on a first housing 13. In the first position, the cover 20 opens the loading hole 11, and in the second position, the cover 20 closes the loading hole 11. The magnetic assembly 30 includes a first magnetic element 31, a second magnetic element 32, a third magnetic element 33, and a fourth magnetic element 34. The first magnetic element 31 and the second magnetic element 32 are spaced apart on the cover 20 along the length direction (first direction D1), and the third magnetic element 33 and the fourth magnetic element 34 are spaced apart on the housing 10 along the length direction (first direction D1). The first magnetic element 31, the second magnetic element 32, the third magnetic element 33, and the fourth magnetic element 34 cooperate to keep the cover 20 in the first position or the second position.

[0038] Specifically, the housing 10 is a structure in the charging device 100 that can accommodate and protect the internal components. The material of the housing 10 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the housing 10 is made of plastic, which makes the housing 10 lighter, thereby contributing to the portability of the charging device 100.

[0039] The housing 10 includes a first housing 13 and a second housing 14. The second housing 14 has a loading hole 11. The first housing 13 is mounted on the second housing 14. The second housing 14 is used to accommodate the internal components of the charging device 100. The first housing 13 is used to enclose the area on the second housing 14 except for the loading hole 11. The loading hole 11 is used to accommodate the aerosol generating device 300. Exemplarily, a first electrical connector is provided in the loading hole 11, and the aerosol generating device 300 has a second electrical connector. When the aerosol generating device 300 is inserted into the loading hole 11 and preset conditions are met, the first electrical connector and the second electrical connector are electrically connected, enabling operational interaction between the aerosol generating device 300 and the charging device 100. This operational interaction includes, but is not limited to, power transmission, data transmission, and status detection. Exemplarily, the first electrical connector can be electrically connected to a power supply unit inside the charging device 100, enabling the charging device 100 to charge the aerosol generating device 300. The first electrical connector may include, but is not limited to, a pogo pin (spring pin) and a conductive spring; the second electrical connector may be a structure capable of electrical connection with the pogo pin and the conductive spring. The preset conditions will be described later in the section on Hall effect sensors and will not be elaborated upon here.

[0040] In some embodiments, the shape of the loading hole 11 is approximately the same as the shape of the aerosol generating device 300. This improves the fit of the loading hole 11 to the aerosol generating device 300, reduces movement or shaking of the aerosol generating device 300 within the loading hole 11, and enhances the stability of the aerosol generating device 300 stored in the charging device 100. For example, when the aerosol generating device 300 is approximately cylindrical, the loading hole 11 can also be cylindrical, and the cross-sectional dimensions of the aerosol generating device 300 cut by a plane perpendicular to the insertion direction (third direction D3) are approximately the same as the cross-sectional dimensions of the loading hole 11 cut by a plane perpendicular to the insertion direction. Therefore, when the aerosol generating device 300 is subjected to force, it can rotate freely within the loading hole 11 about the central axis of the loading hole 11. That is, when the aerosol generating device 300 is subjected to force, it can rotate within the loading hole 11.

[0041] In other embodiments, the shape of the loading hole 11 differs from that of the aerosol generating device 300, and the minimum size of the loading hole 11 is greater than the maximum size of the aerosol generating device 300 in the direction perpendicular to the insertion direction. For example, when the cross-section of the loading hole 11 cut by a plane perpendicular to the insertion direction is square, and the cross-section of the aerosol generating device 300 cut by a plane perpendicular to the insertion direction is circular, the side length of the square is greater than the diameter of the circle. This ensures that the aerosol generating device 300 can be smoothly inserted into the loading hole 11 without interfering with the sidewall of the loading hole 11 during insertion, thus guaranteeing the normal operation of the charging device 100. Furthermore, when the aerosol generating device 300 is subjected to force, it can rotate freely within the loading hole 11 about the central axis of the loading hole 11.

[0042] In this application, the length direction of the charging device 100 is taken as the first direction D1, which is also the direction in which the cover 20 slides between the first position and the second position; the width direction of the charging device 100 is taken as the third direction D3, and the height direction of the charging device 100 is taken as the third direction D3, which is also the insertion direction of the aerosol generating device 300.

[0043] The cover 20 is used to open or close the loading hole 11. In the first position, the cover 20 is offset from the loading hole 11, and the cover 20 opens the loading hole 11, allowing the aerosol generating device 300 to be inserted into or removed from the loading hole 11; in the second position, the cover 20 is opposite to the loading hole 11 in the third direction D3, and the cover 20 closes the loading hole 11.

[0044] Magnetic components 30 are disposed on the first shell 13 and the cover 20, and can attract other magnetic components 30 through their own magnetic field. For example, the magnetic component 30 is a permanent magnet, that is, the magnetic component 30 includes an N pole and a S pole. The magnetic component 30 can be cuboid or cylindrical, etc., and can be disposed on the first shell 13 and the cover 20 using a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, threaded connections or snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive or welding. It is understood that the first shell 13 and the cover 20 each include at least one magnetic component 30. When the cover 20 slides to a first position or a second position, the attractive force between the magnetic components 30 can maintain the cover 20 in the first or second position, preventing displacement of the cover 20 due to external forces or vibrations, thereby maintaining the positional relationship between the cover 20 and the first shell 13.

[0045] The first magnetic element 31 and the second magnetic element 32 are spaced apart on the cover 20 along the first direction D1. The first magnetic element 31 and the second magnetic element 32 can be made of magnetic materials. Generally, magnetic materials refer to substances that can directly or indirectly generate magnetism, such as transition elements iron, cobalt, nickel, and their alloys. For example, both the first magnetic element 31 and the second magnetic element 32 are magnets. The cover 20 is provided with fixing holes, and the first magnetic element 31 and the second magnetic element 32 are installed in the fixing holes.

[0046] The first magnetic element 31 can be one or more, without limitation. Similarly, the second magnetic element 32 can be one or more, without limitation. Specifically, the first magnetic element 31 and the second magnetic element 32 can be cylindrical or cuboid, without limitation. For example, the first magnetic element 31 and the second magnetic element 32 of this application are cylindrical, thus reducing the space occupied by the first magnetic element 31 and the second magnetic element 32 on the cover 20. The first magnetic element 31 and the second magnetic element 32 are spaced apart, which reduces interference between them. The distance between the first magnetic element 31 and the second magnetic element 32 can be designed according to actual needs.

[0047] The third magnetic element 33 and the fourth magnetic element 34 are spaced apart on the housing 10 along the first direction D1. The third magnetic element 33 and the fourth magnetic element 34 can be made of magnetic materials. Generally, magnetic materials refer to substances that can directly or indirectly generate magnetism, such as transition elements iron, cobalt, nickel, and their alloys. Exemplarily, both the third magnetic element 33 and the fourth magnetic element 34 are magnets. The housing 10 is provided with fixing holes, and the third magnetic element 33 and the fourth magnetic element 34 are mounted in the fixing holes.

[0048] The third magnetic element 33 can be one or more, without limitation. The fourth magnetic element 34 can also be one or more, without limitation. Specifically, the third magnetic element 33 and the fourth magnetic element 34 can be cylindrical or cuboid, without limitation. Exemplarily, the third magnetic element 33 and the fourth magnetic element 34 of this application are cylindrical, thus reducing the space occupied by the third magnetic element 33 and the fourth magnetic element 34 on the housing 10. The third magnetic element 33 and the fourth magnetic element 34 are spaced apart, which reduces interference between them. The distance between the third magnetic element 33 and the fourth magnetic element 34 can be designed according to actual needs.

[0049] In the charging device 100 of this application, a first magnetic element 31 and a second magnetic element 32 are disposed on the cover 20, and a third magnetic element 33 and a fourth magnetic element 34 are disposed on the housing 10. The first magnetic element 31, the second magnetic element 32, the third magnetic element 33, and the fourth magnetic element 34 can maintain the positional relationship between the housing 10 and the cover 20 under the action of their own magnetic fields, thereby keeping the cover 20 in a first position or a second position, and maintaining the cover 20 in an open or closed state relative to the loading hole 11.

[0050] Please see Figure 7 In some embodiments, the housing 10 has a guide 17 on the side facing the cover 20, and the cover 20 has a guide groove 21 on the side facing the housing 10. The guide 17 extends into the guide groove 21, and the cover 20 slides in the guide groove 21 via the guide 17. On a projection plane perpendicular to the third direction D3, the projection of the guide 17 is located within the projection of the cover 20.

[0051] Specifically, the cover 20 includes a first cover 23 and a second cover 25, with an accommodating space between the first cover 23 and the second cover 25, which communicates with the guide groove 21. The guide groove 21 is provided on the side of the second cover 25 facing the first shell 13. The guide groove 21 extends along a first direction D1. A guide member 17 is provided on the side of the first shell 13 facing the cover 20, and the guide member 17 extends at least partially into the guide groove 21 to form a sliding fit. The guide member 17 can engage the first shell 13 and the cover 20, and guide the sliding of the cover 20. The user can push the cover 20 to slide along the first direction D1, thereby switching between a first position and a second position. For example, the shape of the guide member 17 is adapted to the shape of the guide groove 21; for example, the guide member 17 can be a cylindrical or rectangular protrusion, and the guide groove 21 can be a matching groove. Whether the cover 20 is in the first position, the second position, or any position between the first and second positions, the cover 20 can cover the guide member 17. That is, regardless of the cover 20's position, the outer contour of the guide member 17 lies within the outer contour of the cover 20. This ensures that the guide member 17 is completely concealed by the cover 20, improving the aesthetic appearance of the charging device 100. Furthermore, the cover 20 reduces direct contact between the guide member 17 and external substances (such as dust, liquids, or foreign objects), helping to protect it from environmental influences and ensuring its sliding function remains uninterrupted. In addition, the cover 20 also protects the guide member 17, reducing the risk of damage due to external forces or impacts. A guide groove 21 is provided on the side of the cover 20 facing the first shell 13, so that the guide groove 21 is always hidden between the cover 20 and the first shell 13 and is not exposed to the naked eye, improving the cleanliness of the charging device 100. In addition, after the guide groove 21 is covered by the cover 20, the entry of external substances (such as dust, liquid or foreign objects) into the guide groove 21 can be reduced, ensuring that the sliding function of the guide groove 21 is not interfered with. Magnetic components 30 are disposed on the first shell 13 and the cover 20. The magnetic components 30 on the first shell 13 and the magnetic components 30 on the cover 20 can maintain the positional relationship between the first shell 13 and the cover 20 under the action of their own magnetic fields, thereby keeping the cover 20 in a first position or a second position.

[0052] Please see Figure 5 and Figure 7In some embodiments, the guide groove 21 includes a first sub-groove 211 and a second sub-groove 212 connected in sequence. The first sub-groove 211 is closer to the side of the cover 20 facing the first shell 13. The guide member 17 includes a body portion 171 and a snap-fit ​​portion 173. The body portion 171 is at least partially accommodated in the first sub-groove 211 and the second sub-groove 212. The snap-fit ​​portion 173 is located at the end of the body portion 171 near the cover 20 and is accommodated in the second sub-groove 212.

[0053] Specifically, the guide groove 21 extends in the first direction D1. In the third direction D3, the first sub-groove 211 and the second sub-groove 212 are sequentially connected. For example, the second sub-groove 212 is larger in the second direction D2 than the first sub-groove 211, thus forming a stepped surface between them. The locking portion 173 rests on this stepped surface, thereby connecting the cover 20 and the guide member 17 and ensuring that the guide member 17 does not fall out of the guide groove 21. The locking portion 173 is accommodated within the second sub-groove 212, meaning it is located within the second sub-groove 212. This design provides additional fixing, preventing excessive sliding of the cover 20. Furthermore, the second sub-groove 212 is larger in size than the first sub-groove 211 in the first direction D1. Thus, when the cover 20 is in the first position or the second position, the stepped surfaces at opposite ends of the first direction D1 can support the locking part 173 at either end of the first direction D1, thereby improving the stability of the sliding of the cover 20.

[0054] Please see Figure 7 In some embodiments, the snap-fit ​​portion 173 includes a first limiting surface 1731 and a second limiting surface 1733 connected in sequence, the shapes of the first limiting surface 1731 and the second limiting surface 1733 matching the inner sidewall of the cover 20.

[0055] Specifically, the limiting surfaces (first limiting surface 1731 and second limiting surface 1733) of the latching portion 173 refer to the surfaces of the latching portion 173 located inside the cover 20 and facing the inner wall of the cover 20 in the third direction D3. The first limiting surface 1731 and the second limiting surface 1733 are respectively located on both sides of the latching portion 173 in the first direction D1. When the cover 20 slides to the first position, the first limiting surface 1731 is closer to the inner wall of the cover 20; when the cover 20 slides to the second position, the second limiting surface 1733 is closer to the inner wall of the cover 20. The first limiting surface 1731 and the second limiting surface 1733 are geometrically matched with the inner wall of the cover 20. The matching method can be a curve-to-curve matching or a plane-to-plane matching, depending on the shape of the inner wall of the cover 20. For example, the first limiting surface 1731 and the second limiting surface 1733 of this application are arc surfaces.

[0056] When the cover 20 slides to the first or second position, the first limiting surface 1731 or the second limiting surface 1733 matches the shape of the inner wall, which increases the contact area between the first limiting surface 1731 or the second limiting surface 1733 and the inner wall, resulting in a more uniform stress distribution and reducing the risk of fatigue or damage due to stress concentration. On the other hand, the locking part 173 will not be stuck by the inner wall due to shape mismatch during sliding, ensuring that the sliding stroke of the groove in the first direction D1 is sufficient.

[0057] Please see Figure 7 In some embodiments, on the projection plane perpendicular to the third direction D3, the projection area of ​​the first limiting surface 1731 is greater than the projection area of ​​the second limiting surface 1733.

[0058] Specifically, when the cover 20 slides to the second position, the cover 20 is slidably connected to the guide 17 on the side away from the loading hole 11 in the first direction D1, while the cover 20 is suspended on the side closer to the loading hole 11 in the first direction D1. Since the cover 20 needs to cover the loading hole 11 in the second position, the suspended edge of the cover 20 will be subjected to certain stress. In this case, the projected area of ​​the first limiting surface 1731 is larger, which can increase the contact area between the guide 17 and the cover 20, thereby improving the support of the guide 17 for the cover 20. The larger contact area helps to disperse stress and reduce local stress concentration, thereby reducing the risk of the cover 20 deforming or being damaged due to excessive stress.

[0059] Please see Figure 6 and Figure 7 In some embodiments, on the third-party direction D3, the first housing 13 is provided with a through mounting hole 131, and at least a portion of the body portion 171 is accommodated in the mounting hole 131.

[0060] Specifically, the mounting hole 131 is used to mount the guide 17 to the first housing 13. Further, in one assembly method, at least a portion of the body portion 171 passes through the mounting hole 131, and the end of the body portion 171 in the third direction D3 away from the snap-fit ​​portion 173 is connected to the first housing 13 by a fastener 50. Exemplarily, the fastener 50 can be a screw. Thus, for the guide 17, the guide 17 has a snap-fit ​​portion 173 at one end in the third direction D3, the snap-fit ​​portion 173 is slidably connected to the guide groove 21, and the guide 17 is connected to the first housing 13 at one end in the third direction D3 by the fastener 50, thereby forming a connection between the cover 20, the guide 17, and the first housing 13. It is understood that the shape of the mounting hole 131 matches that of the body portion 171. The mounting hole 131 can be circular or other shapes. The cross-sectional shape of the mounting hole 131, obtained by the plane perpendicular to the third direction D3, may be different at different positions in the third direction D3. It is understood that the shape of the mounting hole 131 matches the body part 171, which can restrict the degree of freedom of movement of the body part 171 in the plane perpendicular to the third direction D3, and ensure that the body part 171 will not shift or wobble after installation.

[0061] Please see Figure 6 and Figure 7 In some embodiments, the mounting hole 131 includes a first sub-hole 1311 and a second sub-hole 1312 connected in sequence. The first sub-hole 1311 is closer to the side of the first shell 13 facing the cover 20. The outer wall of the body portion 171 is provided with a first protrusion 175, which is located between the cover 20 and the first shell 13, forming a gap 179 between the cover 20 and the first sub-shell. The outer wall of the body portion 171 is provided with a second protrusion 177. A stepped surface is formed between the first sub-hole 1311 and the second sub-hole 1312. The second protrusion 177 is accommodated in the first sub-hole 1311 and supported by the stepped surface.

[0062] Specifically, the outer wall of the main body 171 is provided with a first protrusion 175. The first protrusion 175 can be one or multiple. Exemplarily, this application includes two first protrusions 175, which are arranged along a first diagonal M centered on the main body 171 to ensure uniform force distribution on the cover 20 during sliding. The first protrusions 175 are located between the cover 20 and the first shell 13, forming a gap 179 between them. The gap 179 reduces friction between the cover 20 and the first shell 13 during sliding, preventing wear or interference due to excessive contact between the cover 20 and the first shell 13, thereby improving the smoothness of the cover 20's sliding. When multiple first protrusions 175 are included, the multiple first protrusions 175 have the same size and position in the third direction D3, thereby ensuring the consistency of the gap 179.

[0063] The outer wall of the main body 171 is provided with a second protrusion 177. In the third direction D3, the second protrusion 177 is further away from the snap-fit ​​portion 173 than the first protrusion 175. In the third direction D3, the first sub-hole 1311 and the second sub-hole 1312 are arranged opposite to each other, wherein the cross-sectional area of ​​the first sub-hole 1311 in the XY plane is larger than that of the second sub-hole 1312, thus forming a stepped surface between the first sub-hole 1311 and the second sub-hole 1312. It is understood that the shape of the mounting hole 131 matches the main body 171. The matching of the second protrusion 177 with the stepped surface can prevent the main body 171 from rotating within the mounting hole 131. The second protrusion 177 can be one or more. Exemplarily, the second protrusion 177 of this application includes two, and the two second protrusions 177 are arranged along the second diagonal N with the main body 171 as the center, ensuring that the second protrusion 177 is stably positioned within the first sub-hole 1311 and is not prone to displacement. Furthermore, in the embodiments of this application, the first diagonal M and the second diagonal N are perpendicular, which can further make the first protrusion 175 and the second protrusion 177 evenly distributed on the outer side wall of the body portion 171, reduce local stress concentration, maintain the position of the guide 17, and ensure the smooth sliding of the cover 20.

[0064] Please see Figure 3 and Figure 4 In some embodiments, the magnetic poles of the first magnetic element 31 and the second magnetic element 32 facing the first housing 13 are opposite, and the aerosol generating apparatus 300 also includes a Hall sensor 40. The Hall sensor 40 is used to respond to the first magnetic element 31 or the second magnetic element 32 to detect the position of the cover 20.

[0065] Specifically, the Hall sensor 40 is an active magnetoelectric conversion device that uses the Hall effect to convert a magnetic input signal into an electrical signal. Hall sensors 40 can be classified according to their sensing method into unipolar Hall sensors 40, bipolar Hall sensors 40, and omnipolar Hall sensors 40. The Hall sensor 40 responds to one of the magnetic elements, the first magnetic element 31 and the second magnetic element 32, which reduces magnetic interference from the other magnetic element, facilitating accurate identification of the cover 20's position and improving the accuracy of detecting whether the cover 20 is open or closed. For example, the Hall sensor 40 is a unipolar Hall sensor 40, which is used to respond to the first magnetic element 31 or the second magnetic element 32. Thus, the unipolar Hall sensor 40 generates a low level when the first magnetic element 31 is near, a high level when the first magnetic element 31 is far away, and maintains a high level when the second magnetic element 32 is near or far away. Alternatively, the unipolar Hall sensor 40 can generate a low level when the second magnetic element 32 is near, a high level when the second magnetic element 32 is far away, and maintain a high level when the first magnetic element 31 is near or far away. The low level includes the case of 0.

[0066] When the cover 20 is in the first position, the distance between the Hall sensor 40 and the first magnetic element 31 or the second magnetic element 32 is less than the response distance, which is the maximum distance at which the Hall sensor 40 can respond to the magnetic element. This ensures that the Hall sensor 40 can generate a response when the cover 20 is in the first position, allowing the state of the cover 20 to be detected by the level of voltage. In some embodiments, when the cover 20 is in the second position, the distance between the Hall sensor 40 and the first magnetic element 31 or the second magnetic element 32 is greater than the response distance, which is the maximum distance at which the Hall sensor 40 can respond to the magnetic element. This ensures that the Hall sensor 40 does not generate a response when the cover 20 is in the second position, allowing the state of the cover 20 to be detected by the level of voltage.

[0067] For example, the unipolar Hall sensor 40 of this application only responds to the S pole. The magnetic pole of the first magnetic element 31 facing away from the first shell 13 is the N pole, and the magnetic pole of the first magnetic element 31 facing the first shell 13 is the S pole. The magnetic pole of the second magnetic element 32 facing away from the first shell 13 is the S pole, and the magnetic pole of the second magnetic element 32 facing the first shell 13 is the N pole. When the cover 20 is in the first position, the distance between the Hall sensor 40 and the first magnetic element 31 is less than the response distance, and the Hall sensor 40 generates a first level. When the cover 20 is in the second position, the distance between the Hall sensor 40 and the second magnetic element 32 is greater than the response distance, and the Hall sensor 40 generates a second level. The first level and the second level are different in magnitude, so the cover 20 can be detected as being in the first position or the second position based on the level.

[0068] Please see Figure 3 and Figure 4 In some embodiments, the charging device 100 further includes a control element capable of acquiring the position of the cover 20 detected by the Hall sensor to indicate the behavior of the charging device 100.

[0069] Specifically, the control element can acquire the position information of the cover 20 detected by the Hall sensor and instruct the charging device 100 to perform the operation based on this information. Specifically, when the cover 20 is in the first position (open loading hole 11), the Hall sensor has a first level, the control element receives the first level and instructs the charging device 100 not to perform a charging operation. Thus, the charging device 100 can avoid the risk of leakage that may occur due to the exposure of the first electrical connector in the loading hole 11 when the cover 20 is in the first position, ensuring the safety of the charging device 100 in use.

[0070] With the cover 20 slid to the second position (the state where the loading hole 11 is closed), the Hall sensor has a second level. The control element receives the second level and instructs the charging device 100 to perform a charging operation. That is, the preset conditions mentioned above include whether the second level is met. When the aerosol generating device 300 is inserted into the loading hole 11 and the preset conditions are met (e.g., the aerosol generating device 300 is correctly inserted and the first electrical connector is electrically connected to the second electrical connector on the aerosol generating device 300), the charging device 100 will begin charging the aerosol generating device 300. In this way, the charging device 100 ensures that the charging process will only start when the cover 20 is in the second state and the aerosol generating device 300 is correctly inserted, thereby improving the safety and reliability of charging.

[0071] In addition, the Hall sensor can be integrated with other functions of the charging device 100, such as monitoring the state changes of the cover 20 during charging. If the cover 20 is detected to be accidentally opened (i.e., the cover 20 is slid to a position other than the second position), the charging device 100 can immediately suspend charging to further enhance safety.

[0072] Please see Figure 3 In some embodiments, in the first position, the Hall sensor 40 is opposite the first magnetic element 31 in the third direction D3.

[0073] Specifically, since the sensing intensity of the Hall sensor 40 is proportional to the magnetic flux density, the shorter the distance, the smaller the attenuation of the magnetic flux, and the higher the strength and accuracy of the sensing signal. In the first position, the Hall sensor 40 and the first magnetic element 31 are opposite each other in the third direction D3, and the distance between the Hall sensor 40 and the first magnetic element 31 is the shortest. In this way, the Hall sensor 40 can detect the magnetic field of the first magnetic element 31 and output a first level, thereby determining whether the cover 20 is in the first position (the state of the open loading hole 11). In addition, shortening the distance between the Hall sensor 40 and the first magnetic element 31 can also reduce interference from other magnetic elements or external magnetic fields, further improving the reliability of detection.

[0074] Please see Figure 3 and Figure 4 In some embodiments, the third magnetic element 33 and the fourth magnetic element 34 are opposite to the magnetic poles of the first magnetic element 31 or the second magnetic element 32, and the first magnetic element 31, the second magnetic element 32, the third magnetic element 33 and the fourth magnetic element 34 cooperate to keep the cover 20 in a first position or a second position.

[0075] Specifically, the first shell 13 is provided with a fixing hole, and the third magnetic element 33 and the fourth magnetic element 34 are installed in the fixing hole. Exemplarily, the magnetic pole of the third magnetic element 33 facing the first magnetic element 31 is the S pole, and the magnetic pole of the third magnetic element 33 away from the first magnetic element 31 is the N pole; similarly, the magnetic pole of the fourth magnetic element 34 facing the first magnetic element 31 is the N pole, and the magnetic pole of the fourth magnetic element 34 away from the first magnetic element 31 is the S pole. The first magnetic element 31, the second magnetic element 32, the third magnetic element 33, and the fourth magnetic element 34 can also be combined in other ways, which will not be elaborated here. The third magnetic element 33 and the fourth magnetic element 34 have opposite magnetic poles facing the first magnetic element 31 or the second magnetic element 32, enabling at least one third magnetic element 33 or the fourth magnetic element 34 to cooperate with the first magnetic element 31 or the second magnetic element 32, maintaining the cover 20 in a first position or a second position through opposite-phase attraction.

[0076] Please see Figure 3 and Figure 4 In some embodiments, when the cover 20 is in the first position, the second magnetic element 32 and the third magnetic element 33 are opposite to each other in the third direction D3, and the magnetic pole of the second magnetic element 32 toward the third magnetic element 33 is opposite to the magnetic pole of the third magnetic element 33 toward the second magnetic element 32.

[0077] Specifically, when the cover 20 is in the first position, the magnetic poles of the second magnetic element 32 facing the third magnetic element 33 are opposite to the magnetic poles of the third magnetic element 33 facing the first magnetic element 31. For example, the magnetic pole of the second magnetic element 32 facing the third magnetic element 33 is N, and the magnetic pole of the third magnetic element 33 facing the second magnetic element 32 is S. In this way, the second magnetic element 32 and the third magnetic element 33 attract each other, which can fix the cover 20 in the first position. Furthermore, the second magnetic element 32 and the third magnetic element 33 are opposite each other in the third direction D3, and the distance between the second magnetic element 32 and the third magnetic element 33 in the third direction D3 is short, which can further enhance the attraction between the second magnetic element 32 and the third magnetic element 33.

[0078] Please see Figure 3 and Figure 4 In some embodiments, when the cover 20 is in the second position, the first magnetic element 31 and the fourth magnetic element 34 are opposite to each other in the third direction D3, and the magnetic pole of the first magnetic element 31 toward the fourth magnetic element 34 is opposite to the magnetic pole of the fourth magnetic element 34 toward the first magnetic element 31.

[0079] Specifically, when the cover 20 is in the second position, the magnetic poles of the first magnetic element 31 facing the fourth magnetic element 34 are opposite to the magnetic poles of the fourth magnetic element 34 facing the first magnetic element 31. For example, the magnetic pole of the first magnetic element 31 facing the fourth magnetic element 34 is S, and the magnetic pole of the fourth magnetic element 34 facing the first magnetic element 31 is N. Thus, the first magnetic element 31 and the fourth magnetic element 34 attract each other, which can fix the cover 20 in the second position. Furthermore, the first magnetic element 31 and the fourth magnetic element 34 are opposite each other in the third direction D3, and the distance between the first magnetic element 31 and the fourth magnetic element 34 in the third direction D3 is short, which can further enhance the attraction between the first magnetic element 31 and the fourth magnetic element 34.

[0080] Please see Figure 3 and Figure 4 In some embodiments, there are multiple first magnetic elements 31, second magnetic elements 32, third magnetic elements 33, and fourth magnetic elements 34. Multiple first magnetic elements 31 and multiple second magnetic elements 32 are respectively located on opposite sides of the guide groove 21 in the second direction D2. Multiple third magnetic elements 33 and multiple fourth magnetic elements 34 are located on opposite sides of the guide member 17 of the intermediate assembly in the second direction D2.

[0081] Specifically, multiple first magnetic elements 31, multiple second magnetic elements 32, multiple third magnetic elements 33, and multiple fourth magnetic elements 34 can increase the attraction between the magnetic components 30, thereby improving the stability of the cover 20 in the first and second positions. The number of first magnetic elements 31, second magnetic elements 32, third magnetic elements, and fourth magnetic elements 34 can be one, two, three, or more. For example, in this application, the number of first magnetic elements 31, second magnetic elements 32, third magnetic elements, and fourth magnetic elements 34 is two each. The multiple first magnetic elements 31 and the multiple second magnetic elements 32 are respectively located on opposite sides of the guide groove 21 in the second direction D2, and the multiple third magnetic elements 33 and the multiple fourth magnetic elements 34 are located on opposite sides of the guide member 17 of the intermediate component in the second direction D2. When the cover 20 is in the first position, the multiple second magnetic elements 32 correspond one-to-one with the multiple third magnetic components 30; when the cover 20 is in the second position, the multiple first magnetic elements 31 correspond one-to-one with the multiple fourth magnetic components 30.

[0082] Multiple magnetic components 30 increase the attraction between them, thereby improving the stability of the cover 20 in the first and second positions. Specifically, the distribution of multiple magnetic components allows the magnetic force to act more evenly on the cover 20, reducing instability caused by single-point magnetic force and ensuring that the cover 20 will not shift due to external forces or vibrations during use. Furthermore, the arrangement of multiple magnetic components 30 enhances the redundancy of the system. Even if the magnetic force of some magnetic components weakens due to external environmental factors (such as temperature changes, physical wear, etc.), other magnetic components can still provide sufficient magnetic force to ensure that the cover 20 remains in the correct position.
