When the power in the battery device is consumed, the aerosol generating device needs to be inserted into the charging device to power the aerosol generating device.

[0003] The electrical connection position between a conventional aerosol generator and a charging device can be either at the bottom or the side, but in either contact method, when the aerosol generator is inserted into the charging device, the electrical contacts do not make contact at the same time during the electrical connection, resulting in a small electrical connection area, high impedance, and slow charging speed. Summary of the Invention [Problem to be solved by the invention]

[0012] A second aspect of the present invention provides an aerosol generating system comprising an aerosol generating device and any one of the charging devices according to the above embodiments, the aerosol generating device being detachably attached to the charging device and having a conductive plane.

[0013] In one embodiment, the conductive plane comprises at least two sub-conductive planes distributed with different height gradients.

[0014] In one embodiment, the charging device has a receiving cavity for receiving the aerosol generating device, and the aerosol generating device is an irregularly shaped aerosol generating device that conforms to and fits tightly to the receiving cavity.

[0015] In one embodiment, the charging device further has a first magnetic attraction member, the aerosol generating device has a second magnetic attraction member, the first magnetic attraction member and the second magnetic attraction member are capable of being attracted to each other in a direction perpendicular to the vertical axial direction of the aerosol generating device to fix the aerosol generating device when the aerosol generating device is attached to the charging device, and / or the charging device further has a third magnetic attraction member, the aerosol generating device has a fourth magnetic attraction member, the third magnetic attraction member and the fourth magnetic attraction member are capable of being attracted to each other in the vertical axial direction of the aerosol generating device to fix the aerosol generating device when the aerosol generating device is attached to the charging device.

Fig. 4 is a schematic top view of a charging device in the aerosol generating system shown in Fig. 1.

[0027] Referring to the drawings, one embodiment of the present invention provides a charging device 200 adapted to charge an aerosol generating device 100.

[0028] The aerosol generating device 100 of the present invention refers to a device that generates an aerosol by interacting with an aerosol-forming substrate. Specifically, the aerosol generating device 100 can generate an aerosol by heating the aerosol substrate. More specifically, the aerosol generating device 100 includes an atomizer, such as an electric heater, for heating the aerosol-forming substrate to generate an aerosol.

[0029] The charging device 200 of the present invention can not only accommodate the aerosol generating device 100, but also realize an electrical operation of charging and supplying power to the aerosol generating device 100. Specifically, the charging device 100 can include a battery as necessary. The battery is electrically connected to a charging port so that it can be charged from an external power source such as a commercial power source. The charging device 200 of the present invention further includes a circuit such as at least one microprocessor for controlling charging and discharging of the battery.

[0030] The aerosol generating device 100 is detachably attached to the charging device 200. When the aerosol generating device 100 is attached to the charging device 200, it can be electrically connected to the charging device 200 for charging the aerosol generating device 100.

[0031] In an embodiment of the present invention, the aerosol generating device 100 has a high aspect ratio, i.e., the vertical dimension is greater than the horizontal dimension. Specifically, the aerosol generating device 100 may be a generally cylindrical structure extending longitudinally along a central axis, including a first end and a second end disposed oppositely along the longitudinal axis. The first end has a conductive plane 10, and the second end has an opening for receiving an aerosol-forming substrate.

[0032] The charging device 200 has at least two first electrical contacts 210 linearly arranged along a first direction. Specifically, all the first electrical contacts 210 are linearly arranged along the first direction. In a specific embodiment of the present invention, the first direction is a vertical direction shown in FIG. 4.

[0033] The charging device 200 is configured to receive the aerosol generating device 100 in a second orientation, i.e., when the aerosol generating device 100 is attached to the charging device 200 in the second orientation, each of the first electrical contacts 210 can simultaneously contact the conductive plane 10 of the aerosol generating device 100, where the first direction intersects with the second direction.

[0034] Specifically, the at least two first electrical contacts 210 include at least two of a first positive electrical contact, a first negative electrical contact, or a first signal electrical contact.

[0035] Specifically, the aerosol generating device 100 has a conductive plane 10. More specifically, the conductive plane 10 includes at least a sub-conductive plane of a second electrical contact 20. The second electrical contact 20 may be a second positive electrical contact, a second negative electrical contact, or a second signal electrical contact.

[0036] According to the charging device 100 of the present invention, the aerosol generating device 100 has a conductive plane 10, and the first electrical contacts 210 on the charging device 200 are arranged in a line along the first direction, so that when the aerosol generating device 100 is attached to the charging device 200 along the second direction, it is possible to avoid only a portion of the first electrical contacts 210 coming into contact with the conductive plane 10, and each first electrical contact 210 can simultaneously contact the conductive plane 10 of the aerosol generating device 100, thereby increasing the electrical connection area, reducing the impedance, and improving the charging speed.

[0037] In the embodiment of the present invention, the first direction is perpendicular to the second direction. Specifically, the second direction may be a direction perpendicular to the paper surface shown in Fig. 4 or a horizontal direction shown in Fig. 4. Specifically, the second direction may be a direction perpendicular to the conductive plane 10 or a direction parallel to the conductive plane 10 when the aerosol generating device 100 is attached to the charging device 200.

[0038] Specifically, in the embodiment of the present invention, the charging device 200 has a housing cavity 220 for housing the aerosol generating device 100. Furthermore, the charging device 200 is provided with a receiving port 221 communicating with the housing cavity 220, and the receiving port 221 is for receiving the aerosol generating device 100 into the housing cavity 220 from a second direction.

[0039] Generally, the receiving opening 221 is a narrow opening, and the width of the narrow opening is generally similar to the width of the aerosol generating device 100. When the aerosol generating device 100 is closely aligned with the receiving opening 221, the aerosol generating device 100 can be slid laterally into the receiving cavity 220.

[0040] Therefore, by providing the receiving opening 221, the receiving direction of the aerosol generating device 100 with respect to the charging device 200 can be limited so that the aerosol generating device 100 is received by the charging device 100 accurately in the second direction. This improves the reliability that all the first electrical contacts 210 contact the conductive plane 10 simultaneously.

[0041] Furthermore, all of the first electrical contacts 210 are exposed in the receiving cavity 220. Specifically, all of the first electrical contacts 210 are protruded from the bottom wall of the receiving cavity 220. In this way, after the aerosol generating device 100 enters the receiving cavity 220, the conductive plane 10 can be brought into contact with the first electrical contacts 210 quickly and accurately.

[0042] Specifically, as shown in Fig. 10, the receiving cavity 220 is an open groove formed by a first side wall 230, a second side wall 240, a rear wall 250, and a bottom wall 260 of the charging device 200. Here, the first side wall 230 and the second side wall 240 are spaced apart from each other in a first direction, the rear wall 250 is connected between the first side wall 230 and the second side wall 240 and is arranged opposite the receiving opening 221 in a second direction, and the bottom wall 260 is connected to the same end of the first side wall 230, the second side wall 240, and the rear wall 250. The aerosol generating device 100 may be completely received in the open groove such that no part of the aerosol generating device 100 extends outside the charging device 200.

[0043] When the aerosol generating device 100 is mated with the charging device 200 , i.e., when it is positioned within the receiving cavity 220 , a portion of the aerosol generating device 100 is exposed through the receiving opening 221 .

[0044] 2 again, in order to facilitate removal of the aerosol generating device 100 by the user, in addition to exposure through the receiving opening 221, the charging device 200 is further provided with a communication opening 222 adjacent to the receiving opening 221 and communicating with the storage cavity 220. In this manner, the end face of the second end of the aerosol generating device 100 can be exposed through the communication opening 222. This allows the user to abut against the second end of the aerosol generating device 100, move the aerosol generating device 100 to the outside of the receiving opening 221, and remove it from the storage cavity 220.

[0045] 5 and 6, in the embodiment of the present invention, when the aerosol-generating device 100 is not attached to the charging device 200, the portion of the first electrical contact 210 for contacting the conductive plane 10 is in the same plane. For convenience of description, this plane can be called the contact plane. Thus, when the aerosol-generating device 100 is attached to the charging device 200, the conductive plane 10 contacts the entire contact plane simultaneously, which makes the contact process smooth and improves the reliability of the simultaneous contact.

[0046] The first electrical contact 210 may be in surface contact with the conductive plane 10 or in point contact.

[0047] Additionally, the contact plane may be parallel to the second direction. In another embodiment, the contact plane may be inclined with respect to the second direction to accommodate the mounting angle of the aerosol generating device 100 relative to the charging device 200.

[0048] Specifically, as shown in Figure 7, the portions of the first electrical contact 210 that contact the conductive plane 10 are distributed with different height gradients. In another embodiment, as shown in Figure 8, the conductive plane 10 includes at least two sub-conductive planes, and all the sub-conductive planes are distributed with different height gradients.

[0049] Referring again to Figures 5 and 6, in an embodiment of the present invention, the portion of each first electrical contact 210 for contacting the conductive plane 10 has a centerline along a first direction, and the centerlines of all of the first electrical contacts 210 overlap each other.

[0050] In this manner, when each of the first electrical contacts 210 contacts the conductive plane 10 simultaneously, the contact positions of each of the first electrical contacts 210 can be made to coincide, improving the reliability of the simultaneous contact.

[0051] 9, in an embodiment of the present invention, the conductive plane 10 is a circle whose center point passes through the central axis of the aerosol generating device 100. This allows the aerosol generating device 100 to engage with the charging device 200 at different angles. It should be understood that the shape of the conductive plane 10 is not limited thereto, and in other embodiments, the conductive plane 10 may be other shapes, such as an ellipse, a polygon, etc.

[0052] Furthermore, to realize the electrical connection between the conductive plane 10 and the charging device 200, the conductive plane 10 includes a plurality of conductive regions 11 and at least one insulating region 12, the different conductive regions 11 are spaced apart, and the insulating region 12 is provided between two adjacent conductive regions 11, the conductive plane 10 is electrically connected to the charging device 200 through the plurality of conductive regions 11, and the adjacent conductive regions 11 are insulated from each other through the insulating region 12. It should be understood that the number and arrangement of the conductive regions 11 are not limited and may be set as necessary to meet the requirements of current and signal transmission.

[0053] Specifically, each first electrical contact 210 contacts conductive plane 10 at a corresponding conductive region 11 .

[0054] Further, the conductive plane 10 includes a positive conductive region 111, a negative conductive region 112, and a signal conductive region 113 arranged at a distance from each other, the positive conductive region 111 being used to connect to a second positive electrical contact of the charging device 200, the negative conductive region 112 being used to connect to a second negative electrical contact of the charging device 200, and the signal conductive region 113 being used to communicatively connect to the second signal electrical contact of the charging device 200.

[0055] Specifically, in some embodiments, the positive conductive region 111 is located within a first imaginary ring, the negative conductive region 112 is located within a second imaginary ring, and the signal conductive region 113 is located within an imaginary circle, where the first imaginary ring, the second imaginary ring, and the imaginary circle are coaxially arranged with a gap therebetween, and the three center points of the first imaginary ring, the second imaginary ring, and the imaginary circle all pass through the central axis of the aerosol generating device 100.

[0056] Even when the aerosol generating device 100 is rotated circumferentially during charging, the positive conductive region 111, the negative conductive region 112, and the signal conductive region 113 can still maintain normal electrical and communication connections with the charging device 200 because the conductive plane 10 is flat.

[0057] To further prevent rotation or rattle of the aerosol generating device 100 after it is attached to the charging device 200 and to maintain contact between the conductive plane 10 and the first electrical contact 210, in an embodiment of the present invention, the aerosol generating device 100 is an irregularly shaped aerosol generating device that conforms to and fits snugly against the accommodating cavity 220.

[0058] Here, irregular shape means a non-cylindrical shape, for example, the outer shape of the aerosol generation device 100 is a triangular prism, a square prism, or other asymmetric shape with corners or edges to facilitate positioning of the aerosol generation device 100 in the containing cavity 220. Contiguous adhesion means that when the outer shape of the aerosol generation device 100 is a triangular prism, a square prism, or other asymmetric shape with corners or edges, the containing cavity 221 and the aerosol generation device 100 have the same shape so that they are in close contact with each other.

[0059] 5, in some embodiments, the charging device 200 has a barrier 270. When the aerosol generating device 100 is attached to the charging device 200, the end of the aerosol generating device 100 having the conductive plane 10 may be surrounded by the barrier 270 in order to restrict the aerosol generating device 100. Specifically, the barrier 270 may restrict the aerosol generating device 100 in the longitudinal axial direction or in a direction perpendicular to the longitudinal axial direction of the aerosol generating device 100. This allows the contact pressure between the conductive plane 10 and the first electrical contact 210 to be kept constant, and the contact can be made good by avoiding lateral displacement, thereby avoiding damage to both due to overpressure.

[0060] It should be noted that the first electrical contact 210 is elastically stretchable so that it is pressed from a free height to a working height when it contacts the conductive plane 10 in order to maintain good contact.

[0061] 5 and 9, the barrier 270 is further arc-shaped. The arc-shaped barrier 270 can restrict in two directions at the same time, simplifying the structure and improving the restricting ability at the same time.

[0062] Furthermore, the barrier 270 is a first barrier, and the aerosol generating device 100 has a second barrier 30 that fits the first barrier, and both the first barrier and the second barrier 30 are arc-shaped. In this way, the barrier 270 and the end of the aerosol generating device 100 can be better fitted to each other, and rotation of the aerosol generating device 100 relative to the charging device 200 can be further prevented.

[0063] Specifically, the partition 270 is an inner wall of the receiving cavity 211 .

[0064] In order to protect the end of the aerosol generating device 100 having the conductive plane 10, the material of the partition 270 is a plastic material, but in other embodiments, it may be other materials such as silica gel, and is not particularly limited.

[0065] Based on a similar inventive concept, one embodiment of the present invention provides an aerosol generating system 1000 including an aerosol generating device 100 and any one of the charging devices 200 of the above embodiments. The aerosol generating device 100 is detachably attached to the charging device 200 and has a conductive plane 10.

[0066] The aerosol generating device 100 may be provided by any of the above embodiments, and therefore detailed description will not be repeated.

[0067] 10, in some embodiments, the charging device 200 further includes a first magnetically attractive member 275, and the aerosol generating device 100 includes a second magnetically attractive member 40, and the first magnetically attractive member 275 and the second magnetically attractive member 40 are capable of being attracted to each other in a direction perpendicular to the longitudinal axis of the aerosol generating device 100 to fix the aerosol generating device 100 when the aerosol generating device 100 is attached to the charging device 200. Specifically, the longitudinal axis of the aerosol generating device 100 is the Z direction shown in FIG. 10, and the direction perpendicular to the longitudinal axis of the aerosol generating device 100 is at least one of the X direction and the Y direction shown in FIG. 10.

[0068] In this way, when the aerosol generating device 100 is attached to the charging device 200, the first magnetic attraction member 275 and the second magnetic attraction member 40 are attracted to each other and fixed to the charging device 200, thereby effectively preventing rotation and rattling of the aerosol generating device 100 and ensuring good contact between the conductive plane 10 and the first electrical contact 210.

[0069] Specifically, the first magnetically attractive member 275 is brought into close contact with the rear wall 250, and the second magnetically attractive member 40 is brought into close contact with the inner wall of the housing 50 of the aerosol generating device 100. When the aerosol generating device 100 is accommodated in the accommodating cavity 220, the aerosol generating device 100 is fixed in the accommodating cavity 220 by mutual attraction between the first magnetically attractive member 275 and the second magnetically attractive member 40.

[0070] The number of the first magnetic attraction members 275 and the second magnetic attraction members 40 is not limited to 1. When the number of the first magnetic attraction members 275 and the second magnetic attraction members 40 is at least two, the second magnetic attraction members 40 are arranged at intervals in the vertical direction of the aerosol generating device 100, and correspondingly, the first magnetic attraction members 275 are arranged at intervals in the height direction of the charging device 200.

[0071] As shown in FIG. 6, in some embodiments, the charging device 200 further has a charging limiting plane 280 from which the first electrical contact 210 protrudes, and the charging limiting plane 280 can be limited along the longitudinal axial direction of the aerosol generating device 100 when the aerosol generating device 100 is attached to the charging device 200.

[0072] By providing the charge limiting plane 280, it is possible to prevent the first electrical contact 210 from being damaged and prone to failure due to overpressure applied to the first electrical contact 210 by the conductive plane 100 of the aerosol generating device 100.

[0073] The charging device 200 includes a charging body 285 and a charging base 290 on which all of the first electrical contacts 210 are provided. Specifically, the charging base 290 has a charging limiting plane 280.

[0074] As shown in FIG. 11, the charging device 200 further has a third magnetic attraction member 295, and the aerosol generating device 100 has a fourth magnetic attraction member, and the third magnetic attraction member 295 and the fourth magnetic attraction member are capable of being attracted to each other in the vertical axial direction of the aerosol generating device 100 to fix the aerosol generating device 100 when the aerosol generating device 100 is attached to the charging device 200.

[0075] In this way, when the aerosol generating device 100 is attached to the charging device 200, the third magnetic attraction member 295 and the fourth magnetic attraction member are attracted to each other and fixed to the charging device 200, thereby effectively preventing rotation and rattling of the aerosol generating device 100 and ensuring good contact between the conductive plane 10 and the first electrical contact 210.

[0076] Further, the third magnetic attraction member 295 is arranged around all the first electrical contacts 210. Preferably, the number of the third magnetic attraction members 295 is plural, and at least two third magnetic attraction members 295 are arranged on both opposing sides of all the first electrical contacts 210, specifically, at least two third magnetic attraction members 295 may be arranged on both opposing sides of all the first electrical contacts 210 in a direction perpendicular to the first direction. Preferably, the third magnetic attraction member 295 is arc-shaped. This allows the magnetic attraction on both sides of the first electrical contacts 210 to be uniform, and the deterioration of the contact effect can be avoided.

[0077] 2 , in some embodiments, the charging device 200 further includes a limiting cap 296 that is movably attached to the charging body 285 having the receiving cavity 220, thereby exposing or shielding an end of the aerosol generating device 100 that is axially away from the conductive plane 10 in the longitudinal direction when the aerosol generating device 100 is received in the receiving cavity 220.

[0078] In this way, when the aerosol generating device 100 is accommodated in the accommodation cavity 220 and charged by the charging device 200, the limiting cap 296 can be moved toward the accommodation cavity 220 to shield and protect the aerosol generating device 100. When charging of the aerosol generating device 100 is completed, the limiting cap 296 can be moved away from the accommodation cavity 220 to remove the aerosol generating device 100.

[0079] Preferably, the limiting cap 296 is a sliding cap that is slidably connected to the charging body 285 .

[0080] The charging device 200 and the aerosol generating system 1000 provided by the embodiment of the present invention have the following beneficial effects.

[0081] Since the aerosol generating device 100 has a conductive plane 10 and the first electrical contacts 210 on the charging device 200 are arranged in a line along the first direction, when the aerosol generating device 100 is attached to the charging device 200 along the second direction, it is possible to avoid that only a portion of the first electrical contacts 210 contacts the conductive plane 10, and each first electrical contact 210 can contact the conductive plane 10 of the aerosol generating device 100 simultaneously, thereby increasing the electrical connection area, reducing the impedance, and improving the charging speed.
