Batteries enable the heating or atomization of aerosol-generated products.

[0059] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0060] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0062] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0063] The first aspect of this embodiment relates to an aerosol generating apparatus that can be used in conjunction with an aerosol generating product. The aerosol generating product has an aerosol generating matrix, which, when heated, can generate aerosols for users to inhale.

[0064] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. The aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, the aerosol-generating matrix may include non-tobacco materials.

[0065] The aerosol-generating matrix can be categorized into solid and liquid matrices based on its state. Solid matrices can include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, and powders, granules, fragments, strips, or flakes. Alternatively, the solid matrix may contain additional tobacco or non-tobacco volatile aroma compounds contained within microcapsules. These microcapsules melt during heating of the solid matrix, releasing the internal matrix upon heating. Liquid matrices can include liquids such as glycerol or propylene glycol, which vaporize upon heating to generate inhalable aerosols.

[0066] For example, the applicant disclosed details of an aerosol generating apparatus for generating aerosols using a heatable liquid aerosol generating matrix in Chinese patent application CN119949577A, the full text of which is incorporated herein by reference. Similarly, the applicant disclosed details of an aerosol generating apparatus for generating aerosols using a heatable solid aerosol generating matrix in patent CN221449887U, the full text of which is incorporated herein by reference.

[0067] Please see the appendix Figure 1 In an embodiment, the aerosol generating apparatus may include a heating mechanism, such as an atomizer 100, and a power supply unit 200 for supplying power to the heating mechanism, such as the atomizer 100; wherein the heating mechanism, such as the atomizer 100, may include a heater 120 for heating a solid aerosol generating matrix or a liquid aerosol generating matrix.

[0068] The power supply unit 200 includes a receiving cavity 10 disposed at one end along the length direction and used to receive at least a portion of the atomizer 100. At least a portion of the atomizer 100 is received and housed inside the receiving cavity 10. The power supply unit 200 is electrically connected to the atomizer 100 to supply power to the atomizer 100.

[0069] Please see the appendix Figure 1 - Appendix Figure 4 In this embodiment, the aerosol generating device includes a heater 120, a battery cell 1, a housing 2, a main circuit board 3, a charging assembly 4, and an end cap 5. The heater 120 heats the aerosol generating matrix to generate aerosols; the housing 2 has a proximal end 21 and a distal end 22 facing away from each other; the housing 2 has an opening 221 located at the distal end 22; the battery cell 1 provides power; the main circuit board 3 is located between the battery cell 1 and the proximal end 21, is electrically connected to the battery cell 1, and is configured to control the battery cell 1 to provide power to the heater 120; the end cap 5 closes the opening 221 at the distal end 22 of the housing 2 and provides support for the battery cell 1 at the distal end 22; the end cap 5 and the housing 2 are... The battery cell 1 is detachably connected and can be removed from the housing 2 to open the opening 221 at the distal end 22 of the housing 2, thereby allowing the battery cell 1 to be independently removed or replaced from the opening 221 at the distal end 22 of the housing 2; the charging assembly 4 is securely arranged on the end cover 5 for charging the battery cell 1; the charging assembly 4 is electrically connected to the main circuit board 3 when the end cover 5 is connected to the housing 2, thereby indirectly establishing a conductive connection with the battery cell 1; and the charging assembly 4 can be detached from the housing 2 along with the end cover 5, thereby disconnecting the electrical connection from the main circuit board 3.

[0070] Specifically, heater 120 includes a heating element, which typically includes a resistance heating element and an auxiliary substrate for the fabrication of the resistance heating element. For example, in some embodiments, the resistance heating element is in the shape or form of a spiral coil. Alternatively, in other embodiments, the resistance heating element is in the form of a conductive trace bonded to a substrate. Alternatively, in other embodiments, the resistance heating element is in the shape of a sheet. Alternatively, in other embodiments, the heating element utilizes the principle of electromagnetic induction and can be heated by a changing magnetic field. Alternatively, in other embodiments, the heating element is an infrared heater 120 that heats the aerosol generating matrix by radiating infrared rays into the aerosol generating matrix to generate aerosols.

[0071] The overall design of the outer casing 2 is variable, and the type or configuration of the external body that defines the overall size and shape of the aerosol generating device is also variable. Typically, the elongated body of the outer casing 2 can be formed from a single integral shell structure, or the elongated body can be formed from two or more separable shell structures. The outer casing 2 essentially defines the outer surface of the aerosol generating device; the outer casing 2 has a proximal end 21 and a distal end 22 facing away from the user, wherein the proximal end 21 is the end closer to the user's suction; and the distal end 22 is the end farther from the user's inhalation.

[0072] In some examples, the housing 2 may be formed wholly or partially from a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating-over plastic, ceramics, etc.

[0073] In this embodiment, the battery cell 1 is constructed in a cylindrical shape; or the battery cell 1 has a cylindrical main body portion. The battery cell 1 or the main body portion of the battery cell 1 can be a lithium battery, a nickel-based battery, etc. Furthermore, the battery cell 1 or the main body portion of the battery cell 1 is a commonly used pouch battery. The battery cell 1 can be used to supply power to the heater 120, and the battery cell 1 is removably housed inside the housing 2. Specifically, an opening 221 is formed at the distal end 22 of the housing 2, and the radial dimension of the opening 221 matches the width dimension of the outer cross-section of the battery cell 1 (i.e., the radial dimension of the opening 221 is slightly larger than the width dimension of the outer cross-section of the battery cell 1) to facilitate the insertion or removal of the battery cell 1 into or from the housing 2 through the opening 221, thereby enabling maintenance or replacement of the battery cell 1.

[0074] In this embodiment, the main circuit board 3 is arranged between the battery cell 1 and the proximal end 21, and is fixed by a groove limiting structure within the housing 2. The main circuit board 3 is electrically connected to the battery cell 1 and is configured to control the battery cell 1 to provide power to the heater 120. It should be noted that the power control includes the main circuit board 3 being used to control the battery cell 1 to continuously output power to the heater 120, so that the heater 120 continues to heat, and it can also be used to control the battery cell 1 to stop outputting power, so that the heater 120 stops heating. Of course, the main circuit board 3 can also be used to control the output power of the battery cell 1, so that the heater 120 has multiple different heating temperature operating modes, thereby adapting to the user's adjustment of multiple operating modes for the aerosol generating device.

[0075] Furthermore, the end cap 5 is detachably connected to the outer casing 2. This detachable connection includes, but is not limited to, using snap-fit, threaded engagement, interference fit, or even various fasteners to achieve the connection. After the battery cell 1 is inserted into the outer casing 2, the end cap 5 connects to the outer casing 2 to adaptively close the opening 221, while simultaneously supporting the battery cell 1 at its distal end 22. Therefore, in this embodiment, the end cap 5 not only closes the opening 221 of the outer casing 2 to isolate the internal components from the outside, but also provides sufficient support for the battery cell 1 along the length extension direction of the outer casing 2. When the battery cell 1 needs to be disassembled for maintenance or replacement, the end cap 5 can be separated from the outer casing 2, and the battery cell 1 can be independently removed from the opening 221 at the distal end 22 of the outer casing 2 by slight shaking or gentle jiggle.

[0076] In this embodiment, the charging component 4 is fixed to the end cover 5. It can be embedded inside the end cover 5, or it can be fixed to the side of the end cover 5 facing the battery cell 1 by means of snap-fit ​​or fasteners. The charging component 4 connects to an external power source and then conductively connects to the main circuit board 3 to charge the battery cell 1. The current flows from the external power source to the charging component 4, then from the charging component 4 into the main circuit board 3, and finally from the main circuit board 3 into the battery cell 1.

[0077] In this embodiment, the charging component 4 is disposed on the end cover 5. When the end cover 5 is separated from the outer casing 2, the charging component 4 can be disconnected from the main circuit board 3.

[0078] This aerosol generating device not only enables the rapid removal and insertion of the battery cell 1, but also allows for status control via the main circuit board 3, while simultaneously meeting battery life requirements under external power supply via the charging component 4, thus avoiding user anxiety about battery life.

[0079] Please see the appendix Figure 3 and attached Figure 5Optionally, the charging component 4 includes a charging interface 41 and a charging circuit board 42 connected to the charging interface 41.

[0080] Specifically, the outer wall of the end cover 5 forms a perforation 51, at least a portion of the charging interface 41 is placed inside the perforation 51, and the charging interface 41 can be of the conventional Type-C type to facilitate the insertion of the Type-C interface of the power adapter. At the same time, the charging circuit board 42 is embedded and fixed inside the end cover 5.

[0081] It should be noted that the end cap 5 adopts a split structure and forms a space inside for limiting and installing the charging circuit board 42, so as to ensure the modularity of the end cap 5.

[0082] Furthermore, the aerosol generating device also includes a flexible first electrical contact 8, which extends from the main circuit board 3 toward the distal end 22 and is used to establish a conductive connection between the battery cell 1 and the main circuit board 3; the battery cell 1 abuts against the first electrical contact 8 and thus establishes a conductive connection with the main circuit board 3; when the battery cell 1 is removed from the housing 2, it separates from the first electrical contact 8 and thus disconnects from the main circuit board 3.

[0083] Specifically, part of the first electrical contact 8 can be soldered to the main circuit board 3, while another part of the first electrical contact 8 is used to establish an electrical contact relationship with the battery cell 1.

[0084] In some examples, the first electrical contact 8 can be a flexible conductive pin to ensure reliable electrical contact. Specifically, one end of the conductive pin is fixed to the edge of the main circuit board 3 by plugging, soldering, or a combination of plugging and soldering, while the other end of the conductive pin abuts against the electrical connection end of the battery cell 1. When the battery cell 1 is placed into the housing 2, the end cap 5 supports the battery cell 1 in the accurate installation position. During this process, the electrical connection end of the battery cell 1 contacts and squeezes the flexible contact end of the conductive pin, thereby compressing the conductive pin to press against the electrical connection end of the battery cell 1, so that a stable electrical connection relationship can be maintained between the battery cell 1 and the main circuit board 3.

[0085] It should be noted that the electrical connection end of battery cell 1 can be adapted to form a slot for the conductive pin, so that the conductive pin can achieve conductive connection between battery cell 1 and main circuit board 3 by means of "male and female" plug-in. Of course, the positions of the conductive pin and the slot need to be consistent.

[0086] In other examples, the first electrical contact 8 can be in the form of an elastic conductive sheet to ensure reliable electrical contact. Specifically, one end of the elastic conductive sheet is welded and fixed to the edge of the main circuit board 3, and the elastic contact end of the elastic conductive sheet is used to abut against the battery cell 1. When the battery cell 1 is inserted, the end cap 5 is used to support the battery cell 1 in the accurate installation position. During this process, the electrical connection end of the battery cell 1 contacts and presses against the elastic contact end of the elastic conductive sheet, thereby compressing the elastic conductive sheet to abut against the electrical connection end of the battery cell 1, so that a stable electrical connection relationship can be maintained between the battery cell 1 and the main circuit board 3.

[0087] Optionally, the battery cell 1 includes a first end 11 facing the proximal end 21 and a second end 12 away from the first end 11; the battery cell 1 has a first electrode 13 and a second electrode 14, both of which are arranged at the first end 11.

[0088] In this embodiment, the first electrode 13 and the second electrode 14 can be used to form the positive and negative electrodes, respectively. Correspondingly, two parallel first electrical contacts 8 are respectively provided for the first electrode 13 and the second electrode 14, and can form conductive connections with the first electrode 13 and the second electrode 14, respectively. In this aerosol generating device, the positive and negative electrodes of the battery cell 1 are both arranged on the first end 11. By using the two first electrical contacts 8, after the battery cell 1 is inserted, the electrical contact state of the positive and negative electrodes can be kept consistent, thereby ensuring the stability of the electrical connection state. On the other hand, the first electrode 13 and the second electrode 14 are arranged on the same side of the battery cell 1, which also allows the two first electrical contacts 8 to be adaptively arranged in parallel, thereby reducing the length of the aerosol generating device and avoiding excessive size.

[0089] Furthermore, the charging component 4 and the second terminal 12 are not electrically connected.

[0090] In this embodiment, although the charging component 4 is close to the second end 12 of the battery cell 1, there is no electrical connection between them. The charging component 4 needs to form an electrical connection with the main circuit board 3 before it can indirectly form an electrical connection with the battery cell 1. Therefore, the charging component 4 and the second end 12 can be separated by a gap or by an insulating structure.

[0091] Furthermore, the aerosol generating device also includes a conductive lead 7 disposed on the housing 2, one end of which is conductively connected to the main circuit board 3, and the other end is conductively connected to the charging component 4.

[0092] Specifically, the main circuit board 3 is located near the first end 11 of the battery cell 1, while the charging assembly 4 is located near the second end 12 of the battery cell 1. The main circuit board 3 and the charging assembly 4 are separated by the battery cell 1. The main circuit board 3 and the charging assembly 4 are electrically connected by conductive leads 7.

[0093] In this embodiment, the conductive lead 7 is a flexible wire with an insulating layer on the outside. The conductive lead 7 can be bent and folded to adapt to different housing structures 2. At the same time, the diameter of the conductive lead 7 is very small and does not occupy extra space inside the housing 2, thus ensuring that the battery cell 1 has sufficient installation space.

[0094] Please see the appendix Figure 6 - Appendix Figure 8 Furthermore, the end cap 5 is also provided with a second electrical contact 6 that is electrically connected to the charging component 4. The housing 2 is provided with a bracket 9 for supporting the battery cell 1. The bracket 9 is provided with a contact hole 91 for the second electrical contact 6 to be inserted. At least a portion of the other end of the conductive lead 7 is bent into the contact hole 91. The second electrical contact 6 and the conductive lead 7 make contact inside the contact hole 91, thereby establishing a conductive connection between the charging component 4 and the main circuit board 3.

[0095] Specifically, the outer shell 2 is fitted onto the bracket 9. The bracket 9 can be fixed inside the outer shell 2 by interference fit or snap-fit ​​to maintain a stable connection between the two. A limiting cavity 93 is formed inside the bracket 9 to accommodate the battery cell 1. The bracket 9 is made of non-metallic material and can be formed by one-piece injection molding. The second electrical contact 6 is a columnar conductive needle, one end of which is welded to the charging circuit board 42, and the other end extends away from the distal end 22 and is used for electrical connection with the conductive lead 7. The bracket 9 has a contact hole 91 corresponding to the position of the second electrical contact 6. The internal guide wire of the conductive lead 7 can be bent and extended into the contact hole 91. When the end cap 5 closes the opening 221, the second electrical contact 6 is inserted into the contact hole 91 and contacts the internal guide wire of the conductive lead 7 inside the contact hole 91, thereby forming a conductive connection between the charging assembly 4 and the main circuit board 3.

[0096] It should be noted that this electrical connection is a direct contact between conductors, and the sum of the outer diameter of the inner wire of the conductive lead 7 and the outer diameter of the second electrical contact 6 should be slightly larger than the diameter of the contact hole 91, so as to ensure that the second electrical contact 6 and the inner wire of the conductive lead 7 have a certain squeezing force when they come into contact, thereby reducing the contact resistance between the two and ensuring a stable connection.

[0097] In this embodiment, the electrical connection is maintained by direct contact between the second electrical contact 6 and the internal guide wire of the conductive lead 7, which facilitates the disassembly of the entire charging assembly 4 and also helps to form a modular assembly between the end cover 5 and the charging assembly 4.

[0098] Optionally, the end cap 5 and the bracket 9 are connected by fasteners 92 to form a fastened connection between the housing 2 and the end cap 5.

[0099] Specifically, a connecting post 94 extends from the bracket 9 toward the distal end 22, and the connecting post 94 extends into the interior of the end cap 5, with a through hole in the end cap 5 through which a fastener 92 passes. The connecting post 94 has an internal thread, and the fastener 92 is a screw.

[0100] In this embodiment, the fastener 92 passes through the through hole and is screwed into the internal thread of the connecting post 94. Based on the fit between the bracket 9 and the outer shell 2, the outer shell 2 and the end cap 5 are securely connected. When the screwed fit between the fastener 92 and the connecting post 94 is released, the secure connection between the end cap 5 and the outer shell 2 is naturally released, so the end cap 5 can be directly removed from the distal end 22 of the outer shell 2 without further removal of the end cap 5 from the outer shell 2.

[0101] Those skilled in the art will understand that the number of connecting posts 94 is planned according to the reliability of the connection. In this embodiment, two connecting posts 94 are arranged side by side on the bracket 9.

[0102] Another aspect of this embodiment also relates to an aerosol generating device, which includes a proximal end 21 and a distal end 22 facing away from each other, as well as a heater 120, a battery cell 1, a main circuit board 3, a flexible first electrical contact 8, and a charging assembly 4. The heater 120 is used to heat the aerosol generating matrix to generate aerosols; the battery cell 1 is used to supply power; the battery cell 1 has a first end 11 facing the proximal end 21 and a second end 12 away from the first end 11; the battery cell 1 has a first electrode 13 and a second electrode 14, both of which are arranged at the first end 11; the main circuit board 3 is located between the battery cell 1 and the proximal end 21; the main circuit board 3 is configured to control the battery cell 1 to supply power to the heater 120; a first electrical contact 8 extends from the main circuit board 3 toward the distal end 22; the first electrode 13 and the second electrode 14 of the battery cell 1 abut against the elastic first electrical contact 8 and thus establish a conductive connection with the main circuit board 3; the charging assembly 4 is arranged between the second end 12 and the distal end 22 of the battery cell 1; the charging assembly 4 charges the battery cell 1 by connecting to the main circuit board 3 and thus indirectly establishing a conductive connection with the first electrode 13 and the second electrode 14 of the battery cell 1.

[0103] In this aerosol generating device, the charging component 4 and the main circuit board 3 are separated by the battery cell 1. The main circuit board 3 achieves a conductive connection between the battery cell 1 and the main circuit board 3 by abutting between the first electrode 13 and the second electrode 14 of the battery cell 1 through the elastic first electrical contact 8. The charging component 4 is connected to the main circuit board 3 through the conductive lead 7 to form a conductive connection between the charging component 4 and the main circuit board 3, thereby realizing the indirect connection between the charging component 4 and the first electrode 13 and the second electrode 14 of the battery cell 1 through the main circuit board 3.

[0104] This aerosol generating device creates a layout in which the charging component 4 is located on the non-electrode side of the battery cell 1, expanding the electrical connection between the charging component 4 and the battery cell 1. It also improves the flexibility of the overall layout of the aerosol generating device by making the electrical connection interface between the battery cell 1 and the external power supply more flexible. According to this embodiment, the charging position of this aerosol generating device can be flexibly set at the far end 22 or at a position close to the far end 22.

[0105] Please refer to the appendix again. Figure 3 Another aspect of this embodiment further relates to a power supply body 200 (hereinafter referred to as power supply body 200) for an aerosol generating device, the power supply body 200 including a battery cell 1, a housing 2, a main circuit board 3, a charging assembly 4, and an end cap 5. The battery cell 1 is used for power supply. The housing 2 has a proximal end 21 and a distal end 22 facing away from each other. A receiving cavity 10 is defined by a portion of the housing 2, and the receiving cavity 10 has an opening 101 located at the proximal end 21 for removably receiving a heating mechanism of the aerosol generating device, such as an atomizer 100. The main circuit board 3 is located between the battery cell 1 and the receiving cavity 10. The main circuit board 3 is configured to control the battery cell 1 to supply power to the atomizer 100. The end cap 5 closes the opening 221 of the housing 2 at the distal end 22 and provides support for the battery cell 1 at the distal end 22. The battery cell 1 is detachably connected to the housing 2 and can be removed from the housing 2 to open the opening 221 at the distal end 22 of the housing 2, thereby allowing the battery cell 1 to be independently removed or replaced from the opening 221 at the distal end 22 of the housing 2; the charging assembly 4 is securely arranged on the end cover 5 for charging the battery cell 1; the charging assembly 4 is electrically connected to the main circuit board 3 when the end cover 5 is connected to the housing 2, thereby indirectly establishing a conductive connection with the battery cell 1; and the charging assembly 4 can be detached from the housing 2 along with the end cover 5, thereby disconnecting the electrical connection from the main circuit board 3.

[0106] When the heating mechanism of the aerosol generating device, such as the atomizer 100, is received in the receiving cavity 10, the heating mechanism, such as the atomizer 100, establishes a conductive connection with the main circuit board 3 of the power supply unit 200.

[0107] In this embodiment, the receiving cavity 10 is located at the proximal end 21 and is used to accommodate the atomizer 100. The atomizer 100 has a liquid reservoir for storing a liquid matrix. The battery 1 supplies power to the atomizer 100 via the main circuit board 3, enabling the atomizer 100 to atomize the liquid matrix and combine it with air to form an aerosol for the user to inhale. The atomizer 100 has a gas flow channel and an outlet for the aerosol to pass through. To shorten the length of the gas flow channel and the length of the atomizer 100 itself, the atomizer 100 is positioned at the proximal end 21, allowing the aerosol to enter the user's mouth through the outlet.

[0108] In this embodiment, the power supply unit 200 is detachably connected to the outer casing 2 via the end cover 5, enabling quick removal and replacement of the battery cell 1. Simultaneously, integrating the charging component 4 onto the end cover 5 facilitates modular assembly of the end cover 5's structure.
