Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to a conductive connection structure and a battery assembly. Background Technology

[0002] Electronic cigarettes are heated non-combustible aerosol generating devices. They generate aerosols that can be inhaled by heating but not burning aerosol-generating products through a heating element, thereby reducing the harmful smoke components produced during the combustion process of traditional aerosol-generating products.

[0003] In the battery assembly of an electronic cigarette, the spring-loaded electrode is a spring-loaded elastic electrode that has a pressing and rebound function. The power supply unit of the battery assembly is electrically connected to the atomizing assembly through the spring-loaded electrode to facilitate the replacement and maintenance of the atomizing assembly.

[0004] In related technologies, the spring pin is riveted to the plastic part. In this structure, the large riveting interference force between the plastic part and the spring pin will increase the friction between the spring pin and the plastic part, causing the spring pin to get stuck in the plastic part and have difficulty rebounding, thus affecting the conductivity stability of the spring pin. Utility Model Content

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application provides a conductive connection structure and a battery assembly that can improve the conductivity stability of electrical connections.

[0006] In a first aspect, this application provides a conductive connection structure, comprising:

[0007] A circuit carrier having a signal interface section;

[0008] A connecting component includes an electrical connector, a sheath, and an elastic element. The sheath is fixed to the circuit carrier, the electrical connector is movably inserted through the sheath, and the elastic element is disposed between the electrical connector and the sheath.

[0009] A wire is provided, one end of which is connected to the signal interface portion, and the other end extends out relative to the sheath.

[0010] The conductive connection structure according to the first aspect of this application has at least the following beneficial effects:

[0011] The conductive connection structure of this application, through the coordinated arrangement of the circuit carrier, connecting components, and wires, fixes the sheath to the circuit carrier. The electrical connector passes through the sheath and is connected to the signal interface on the circuit carrier via the wires. The sheath provides guidance and positioning for the assembly of the electrical connector, and the way the sheath is fixed to the circuit carrier avoids radial pressure on the electrical connector, reduces the contact friction between the sheath and the electrical connector, allows the electrical connector to move smoothly along the axial direction of the sheath, and allows the electrical connector to stably compress the elastic element between the sheath and the electrical connector. This enables the electrical connector to make stable and reliable contact with the corresponding electrical structure under the rebound force of the elastic element, effectively solving the problems of electrical connector jamming and difficulty in receiving rebound force, and improving the conductive stability of the electrical connector.

[0012] In some embodiments, the circuit carrier has a mounting hole, and the outer wall of the sheath has a positioning part. The vertical projection of the positioning part on the circuit carrier covers the vertical projection of the mounting hole on the circuit carrier. The sheath passes through the mounting hole, and the positioning part is welded to the side of the circuit carrier opposite to the signal interface part.

[0013] In some embodiments, the sheath extends relative to the side of the circuit carrier closer to the signal interface portion, and the end of the electrical connector connected to the signal interface portion extends relative to the sheath.

[0014] In some embodiments, the sheath is provided with a first limiting portion and a second limiting portion along its own axial direction, the electrical connector is provided with a stop portion that abuts against the first limiting portion, the elastic member is housed in the sheath, and the opposite ends of the elastic member abut against the stop portion and the second limiting portion, respectively.

[0015] In some embodiments, the elastic element is also sleeved on the electrical connector.

[0016] Secondly, this application provides a battery assembly for providing electrical energy to an atomizing assembly, the battery assembly comprising:

[0017] case;

[0018] The conductive connection structure described above is disposed within the housing;

[0019] A power supply unit is installed inside the housing. The power supply unit is electrically connected to the circuit carrier. The end of the electrical connector away from the signal interface is electrically connected to the atomizing component.

[0020] The battery assembly according to the second aspect of this application has at least the following beneficial effects:

[0021] The battery assembly of this application, due to the aforementioned conductive connection structure, also possesses the same technical effects brought by this conductive connection structure. Specifically, the electrical connectors can maintain stable and reliable contact with the corresponding electrical structures under the restoring force of the elastic element, effectively solving the problems of connector jamming and difficulty in receiving restoring force, thus improving the conductive stability of the electrical connectors. Simultaneously, the electrical connectors are inserted into the sheath and connected to the signal interface on the circuit carrier via wires, shortening the connection length of the wires, reducing the wire impedance, and decreasing the overall impedance of the conductive connection structure. This helps the conductive connection structure form a stable conductive loop with the other electrical structures.

[0022] In some embodiments, the electrical connector is capable of applying a holding force toward the circuit carrier to the elastic member under the support of the atomizing component.

[0023] In some embodiments, a partition is formed inside the housing, which divides the cavity of the housing into a first chamber and a second chamber. The first chamber is used to install the atomizing component, and the power supply unit and the circuit carrier are disposed in the second chamber. The partition is provided with a through hole for the electrical connector to pass through.

[0024] In some embodiments, the conductive connection structure further includes a seal located in the second chamber, the seal being connected to the side of the circuit carrier away from the power supply unit and abutting against the partition.

[0025] In some embodiments, the seal has a clearance hole, and the sleeve is clearance-fitted with the clearance hole.

Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] In the battery assembly of an electronic cigarette, the spring-loaded electrode is a spring-loaded elastic electrode that has a pressing and rebound function. The power supply unit of the battery assembly is electrically connected to the atomizing assembly through the spring-loaded electrode to facilitate the replacement and maintenance of the atomizing assembly.

[0046] In related technologies, the spring pin is riveted to the plastic part. In this structure, the large riveting interference force between the plastic part and the spring pin will increase the friction between the spring pin and the plastic part, causing the spring pin to get stuck in the plastic part and have difficulty rebounding, thus affecting the conductivity stability of the spring pin.

[0047] Based on this, one or more embodiments of this application provide a conductive connection structure. By coordinating the circuit carrier, connecting components, and wires, a sheath is fixed to the circuit carrier. Electrical connectors pass through the sheath and are connected to the signal interface on the circuit carrier via wires. The sheath provides guidance and positioning for the assembly of the electrical connectors. The way the sheath is fixed to the circuit carrier avoids radial pressure on the electrical connectors, reduces the contact friction between the sheath and the electrical connectors, allows the electrical connectors to move smoothly along the axial direction of the sheath, and allows the electrical connectors to stably compress the elastic element between the sheath and the electrical connectors. This enables the electrical connectors to make stable and reliable contact with the corresponding electrical structure under the rebound force of the elastic element, effectively solving the problems of electrical connector jamming and difficulty in receiving rebound force, and improving the conductive stability of the electrical connectors.

[0048] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a conductive connection structure 10, including a circuit carrier 100, a connection component 200, and a wire 300.

[0049] The circuit carrier 100 has a signal interface section 110. The connection assembly 200 includes an electrical connector 210, a sheath 220 and an elastic member 230. The sheath 220 is fixed to the circuit carrier 100, the electrical connector 210 is movably inserted through the sheath 220, and the elastic member 230 is disposed between the electrical connector 210 and the sheath 220.

[0050] One end of the electrical connector 210 is connected to the signal interface 110 via a wire 300, and the other end extends out relative to the sheath 220.

[0051] It should be noted that in this application, the electronic atomizing device includes a battery assembly 20 and a cartridge assembly. The conductive connection structure 10 can be configured in the battery assembly 20. The cartridge assembly includes an atomizing component and a liquid storage chamber, etc. The liquid storage chamber is used to store the aerosol generation matrix. The conductive connection structure 10 conductively connects the power supply unit 600 of the electronic atomizing device and the atomizing component, so that the power supply unit 600 supplies power to the atomizing component through the conductive connection structure 10, so that the atomizing component is heated and atomizes the aerosol generation matrix under power, thereby atomizing the aerosol generation matrix to form an aerosol for the user to inhale.

[0052] See also in this application. Figure 3 and Figure 4 The circuit carrier 100 may include a circuit board, such as a PCBA or FPC. For example, the circuit carrier 100 is a PCBA, which gives it a certain structural strength, supporting integrated circuit components and other components. The signal interface section 110 on the circuit carrier 100 refers to the signal interface integrated on the circuit carrier 100, which may be, but is not limited to, interface pads, signal pins, connectors, etc., and is used to transmit electrical signals to the corresponding circuit of the circuit carrier 100.

[0053] See also in this application. Figure 4 , Figure 5 and Figure 6 For the connecting assembly 200, the electrical connector 210 refers to the conductive structure of a single element. The electrical connector 210 is a metal structure, which may be, but is not limited to, a spring pin, a conductive rod, a conductive post, etc.

[0054] For connection component 200, see Figure 4 , Figure 5 and Figure 6 The sheath 220 is a structure sleeved on the electrical connector 210. The sheath 220 can be, but is not limited to, a cannula, syringe, or other structure with an axial channel. The sheath 220 provides guidance and limitation for the electrical connector 210, guiding the electrical connector 210 to move along the axial channel of the sheath 220, while restricting the radial movement or oscillation of the electrical connector 210 along the sheath 220. The sheath 220 can be fixed to the corresponding part of the circuit carrier 100 using SMT (Surface Mount Technology) technology, so that the position of the sheath 220 on the circuit carrier 100 remains stable.

[0055] It should be noted that the sheath 220 does not form an electrical connection with the circuit carrier 100, but only a simple mechanical connection with the circuit carrier 100, which provides support and fixation for the sheath 220.

[0056] For the connecting assembly 200, the elastic element 230 refers to a structure disposed between the sheath 220 and the electrical connector 210 and capable of providing elastic force. The elastic element 230 may be, but is not limited to, a coil spring, a tower spring, etc. The elastic element 230 may be housed within the sheath 220 and form a limiting fit with the electrical connector 210, so that the elastic element 230 can provide an elastic force along the axial direction of the sheath 220 toward the electrical connector 210 with a tendency to extend outward toward the sheath 220.

[0057] For example, see Figure 4 and Figure 6 For the connecting assembly 200, the electrical connector 210 is a spring pin, the sheath 220 is a pin sleeve, the elastic element 230 is a spring, the circuit carrier 100 is a circuit board, the sheath 220 is soldered onto the circuit carrier 100 and is arranged perpendicular to the circuit carrier 100, the elastic element 230 is housed in the sheath 220 and supported at the bottom of the sheath 220, the electrical connector 210 passes through the sheath 220 and abuts against the top of the elastic element 230 inside the sheath 220, so that the elastic element 230 can provide an elastic force along the axial direction of the sheath 220 to the electrical connector 210 with a tendency to extend outward from the sheath 220.

[0058] See Figure 2 and Figure 3 The connection of one end of the electrical connector 210 to the signal interface section 110 via the wire 300 can be understood as follows: one end of the electrical connector 210 is connected to one end of the wire 300, and the other end of the wire 300 is connected to the signal interface section 110. The connection method between the wire 300 and the electrical connector 210 can be soldering, crimping, twisting, etc., and the connection between the wire 300 and the signal interface section 110 can be soldering, crimping, etc. For example, the signal interface section 110 is a pad provided on the circuit carrier 100, and the wire 300 is correspondingly soldered to the pad.

[0059] See Figure 3 and Figure 5 The fact that the other end of the electrical connector 210 extends relative to the sheath 220 can be understood as: the end of the electrical connector 210 that is not connected to the wire 300 extends outside the sheath 220, so that this end of the electrical connector 210 can form an electrical connection with the atomizing component of the electronic atomizing device.

[0060] For example, when the conductive connection structure 10 of this application is configured in an electronic atomizing device, the power supply unit 600 of the electronic atomizing device is electrically connected to the circuit carrier 100, thereby supplying power to the circuit carrier 100. The heating element (such as heating wire, heating coil, heating rod, etc.) of the atomizing component of the electronic atomizing device is connected to the end of the electrical connector 210 that extends relative to the sheath 220. This causes the electrical connector 210 to move a small displacement away from the atomizing component along the axial direction of the sheath 220, compressing the elastic element 230. The elastic force of the elastic element 230 allows the end of the electrical connector 210 that extends relative to the sheath 220 to make close contact with the heating element of the atomizing component, forming a stable electrical connection. The power supply unit 600, the circuit carrier 100, the electrical connector 210, and the atomizing component form a complete conductive circuit. The circuit carrier 100 transmits electrical energy to the heating element of the atomizing component through the electrical connector 210, energizing the atomizing component and heating and atomizing the aerosol generation matrix, thereby atomizing the aerosol generation matrix into an aerosol for the user to inhale.

[0061] When the user pulls out the atomizing component, the electrical connector 210 can be reset to its initial position relative to the sheath 220 under the rebound force of the elastic member 230. The conductive circuit between the power supply unit 600, the circuit carrier 100, the electrical connector 210 and the atomizing component is disconnected, and the electronic atomizing device enters standby or sleep mode.

[0062] Based on the above explanation, it should be added that, in order to avoid the electrical connector 210 pulling on the signal interface 110 and the wire 300 during the axial movement of the sheath 220, the length of the wire 300 can be set to be relatively long, so that the wire 300 is in a relaxed state and compensates for the displacement of the electrical connector 210 along the axial direction of the sheath 220 by its own length.

[0063] The conductive connection structure 10 of this embodiment uses a circuit carrier 100, a connecting component 200, and a wire 300 to fix a sheath 220 to the circuit carrier 100. An electrical connector 210 passes through the sheath 220 and is connected to the signal interface 110 on the circuit carrier 100 via the wire 300. The sheath 220 provides guidance and positioning for the assembly of the electrical connector 210, and the way the sheath 220 is fixed to the circuit carrier 100 avoids radial pressure from the sheath 220 on the electrical connector 210, thus reducing the pressure on the sheath. The contact friction between the sheath 220 and the electrical connector 210 enables the electrical connector 210 to move smoothly along the axial direction of the sheath 220 and to stably compress the elastic element 230 between the sheath 220 and the electrical connector 210. This allows the electrical connector 210 to make stable and reliable contact with the corresponding electrical structure (such as the heating element of the atomizing component) under the rebound force of the elastic element 230, effectively solving the problems of jamming and difficulty in receiving rebound force of the electrical connector 210 and improving the conductivity stability of the electrical connector 210.

[0064] In addition, the electrical connector 210 passes through the sheath 220 and is connected to the signal interface 110 on the circuit carrier 100 via the wire 300, which shortens the connection length of the wire 300, reduces the wire impedance brought by the wire 300, and helps the conductive connection structure 10 as a whole to form a stable conductive circuit with the rest of the electrical structure.

[0065] In some embodiments of this application, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The circuit carrier 100 has a mounting hole 120, and the outer wall of the sheath 220 has a positioning part 221. The vertical projection of the positioning part 221 on the circuit carrier 100 covers the vertical projection of the mounting hole 120 on the circuit carrier 100. The sheath 220 passes through the mounting hole 120, and the positioning part 221 is welded to the side of the circuit carrier 100 away from the signal interface part 110.

[0066] Specifically, the sheath 220 is coaxial with the mounting hole 120, which is a through hole, so that the circuit carrier 100 will not cause structural interference to the movement of the electrical connector 210 along the axis of the sheath 220. A positioning part 221 is provided on the outer wall of the sheath 220 near its bottom end. The positioning part 221 is an annular block surrounding the outer wall of the sheath 220, and the diameter of the positioning part 221 is larger than the diameter of the mounting hole 120.

[0067] Thus, when the sheath 220 passes through the mounting hole 120, the positioning part 221 can be positioned on the periphery of the mounting hole 120, which facilitates the formation of a welding connection with the side of the circuit carrier 100 away from the signal interface part 110, so that the sheath 220 is accurately positioned and fixed on the circuit carrier 100.

[0068] For example, the welding connection between the positioning part 221 and the circuit carrier 100 can be achieved by SMT surface mount technology.

[0069] The above-described structure, with the positioning part 221 on the outer wall of the sheath 220 cooperating with the mounting hole 120 on the circuit carrier 100, enables the sheath 220 to be accurately positioned and fixed on the circuit carrier 100. The welding connection between the sheath 220 and the circuit carrier 100 ensures that the sheath 220 does not exert radial pressure on the electrical connector 210, and the mounting hole 120 provides clearance for the movement of the electrical connector 210, further enabling the electrical connector 210 to move smoothly along the axial direction of the sheath 220, and allowing the elastic member 230 to generate a stable and reliable rebound force on the electrical connector 210, thereby improving the conductivity stability of the electrical connector 210.

[0070] Further, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The sheath 220 extends out from the side of the circuit carrier 100 near the signal interface 110, and the end of the electrical connector 210 connected to the signal interface 110 extends out from the sheath 220.

[0071] Specifically, the two opposite ends of the electrical connector 210 are defined as a first end and a second end, respectively. The first end of the electrical connector 210 is not connected to the wire 300, and its end extends away from the circuit carrier 100 relative to the sheath 220. The second end of the electrical connector 210 is connected to the wire 300, and its end extends closer to the circuit carrier 100 relative to the sheath 220, and is connected to the signal interface portion 110 through the wire 300. The sheath 220 extends out from the side of the circuit carrier 100 closer to the signal interface portion 110 after passing through the mounting hole 120.

[0072] The above-described structure extends the sheath 220 relative to the side of the circuit carrier 100 near the signal interface 110. When the sheath 220 is soldered and fixed to the circuit carrier 100, the flux between the sheath 220 and the circuit carrier 100 is blocked by the portion of the sheath 220 extending from the side of the circuit carrier 100 near the signal interface 110. This reduces the risk of flux entering the interior of the sheath 220 and contacting the electrical connector 210, and further reduces the risk of the electrical connector 210 getting stuck inside the sheath 220 and being unable to move or spring back. This further improves the conductivity stability of the electrical connector 210.

[0073] Furthermore, by having one end of the electrical connector 210 connected to the signal interface 110 extend relative to the sheath 220, the length of the wire 300 between the electrical connector 210 and the signal interface 110 can be shortened, reducing the wire impedance caused by the wire 300 and decreasing the overall impedance of the conductive connection structure 10. This helps the conductive connection structure 10 to form a stable conductive circuit with the rest of the electrical structure.

[0074] In some embodiments of this application, see Figure 3 , Figure 4 , Figure 5 and Figure 6 The sheath 220 is provided with a first limiting part 222 and a second limiting part 223 along its own axial direction. The electrical connector 210 is provided with a stop part 211 that abuts against the first limiting part 222. The elastic member 230 is housed in the sheath 220, and the opposite ends of the elastic member 230 abut against the stop part 211 and the second limiting part 223 respectively.

[0075] Specifically, the first limiting part 222 and the second limiting part 223 are both located inside the sheath 220. The first limiting part 222 is located near the end of the sheath 220 that is away from the circuit carrier 100, and the second limiting part 223 is located near the end of the circuit carrier 100.

[0076] The sheath 220 is cylindrical. The first limiting part 222, the second limiting part 223 and the sheath 220 are integrally formed. The first limiting part 222 and the second limiting part 223 are both provided with through holes through which the power supply connector 210 passes, so as to avoid interference between the two on the axial movement of the power connector 210.

[0077] The electrical connector 210 has a shaft-shaped structure, and the stop portion 211 is provided on the outer wall of the electrical connector 210. Its shape is adapted to the first limiting portion 222 so as to form a stable stop engagement with the first limiting portion 222.

[0078] The elastic element 230 can be a spring, which is housed in the cavity of the sheath 220 and sleeved on the part of the electrical connector 210 located inside the sheath 220.

[0079] In the above structure, when the electrical connector 210 is in the initial position, the stop portion 211 and the first limiting portion 222 are in stop engagement. When the electrical connector 210 moves a certain distance along the axial direction of the sheath 220 towards the circuit carrier 100 under external pressure (the pressure of the atomizing component), the electrical connector 210 drives the stop portion 211 on it to compress the elastic member 230, so that the elastic member 230 forms a large rebound force on the electrical connector 210. When the external pressure acting on the electrical connector 210 is removed, the electrical connector 210 and the stop portion 211 on it are reset to the initial position under the rebound force of the elastic member 230, so that the stop portion 211 and the first limiting portion 222 form stop engagement again. In this way, the electrical connector 210 can be prevented from excessively rebounding and disengaging from the sheath 220, improving the stability of the electrical connector 210 moving along the axial direction of the sheath 220, and also ensuring the functional reliability of the electrical connector 210.

[0080] Further, see Figure 5 and Figure 6 The elastic element 230 is also sleeved on the electrical connector 210.

[0081] Specifically, the elastic element 230 is a spring, which is coaxial with the electrical connector 210 and the sheath 220. The elastic element 230 itself forms an axial cavity through which the power connector 210 passes. The inner diameter of the sheath 220 is greater than or equal to the outer diameter of the elastic element 230, and the inner diameter of the cavity of the elastic element 230 is greater than the outer diameter of the part of the electrical connector 210 that passes through the elastic element 230. This reduces the contact area between the electrical connector 210 and the elastic element 230, and reduces the contact friction between the elastic element 230 and the electrical connector 210.

[0082] In addition, an insulating coating may be provided on the elastic element 230, or the elastic element 230 may be an insulating elastomer such as silicone or rubber, which separates the sheath 220 and the electrical connector 210 while preventing the sheath 220 and the electrical connector 210 from forming a conductive connection.

[0083] In the above structure, the elastic element 230 is housed within the sheath 220 and sleeved on the electrical connector 210. This can separate the sheath 220 and the electrical connector 210 from each other, preventing direct contact between the electrical connector 210 and the sheath 220, and preventing the sheath 220 and the electrical connector 210 from forming a conductive connection that would interfere with the transmission of electrical signals in the electrical connector 210.

[0084] Additionally, see Figure 7 , Figure 8 , Figure 9 and Figure 10 This application embodiment also provides a battery assembly 20, which is used to provide electrical energy to an atomizing component (not shown in the figure). The battery assembly 20 includes a housing 500, a power supply unit 600, and a conductive connection structure 10 of any of the above embodiments.

[0085] The conductive connection structure 10 is disposed inside the housing 500. The power supply unit 600 is installed inside the housing 500 and is electrically connected to the circuit carrier 100. The end of the electrical connector 210 away from the signal interface 110 is electrically connected to the atomizing component.

[0086] It should be noted that the housing 500 refers to the structure used to accommodate and support components such as the conductive connection structure 10 and the power supply unit 600, and it may be, but is not limited to, rectangular, cylindrical, etc.

[0087] The power supply unit 600 can be a battery, such as a lithium-ion battery, which is electrically connected to the circuit carrier 100 and thus provides electrical energy to the circuit carrier 100.

[0088] The following describes the detailed functions of the battery assembly 20 using an example of a battery assembly 20 configured in an electronic atomizing device.

[0089] The electronic atomizing device includes a cartridge assembly and the aforementioned battery assembly 20. The cartridge assembly includes an atomizing component for generating an aerosol matrix. The conductive connection structure 10 includes two connection components 200. The atomizing component has a positive contact and a negative contact. One electrical connection component 210 is in close contact with the positive contact of the atomizing component under the rebound force of the elastic member 230, and the other electrical connection component 210 is in close contact with the negative contact of the atomizing component under the rebound force of the other elastic member 230.

[0090] When the main control chip on the circuit carrier 100 responds to a user instruction (such as the user inhaling and triggering the airflow sensor, or the user pressing the ignition button), it sends a power supply signal to the power supply unit 600. Current flows out from the positive terminal of the power supply unit 600, passes through the circuit on the circuit carrier 100, and then flows through the wire 300 and the electrical connector 210 to the positive contact of the atomizing component. It then flows through the heating element of the atomizing component, causing the heating element to generate heat, heating and atomizing the aerosol generating matrix, thereby atomizing the aerosol generating matrix into an aerosol for the user to inhale. The current then flows from another electrical connector 210 and the wire 300 back to the circuit on the circuit carrier 100, and finally returns to the negative terminal of the power supply unit 600, thus forming a complete conductive circuit.

[0091] It is easy to understand that the battery assembly 20 of this embodiment, due to the configuration of the aforementioned conductive connection structure 10, also possesses the same technical effects brought by the conductive connection structure 10. That is, the electrical connector 210 can make stable and reliable contact with the corresponding electrical structure (such as the heating element of the atomizing component) under the action of the elastic force of the elastic member 230, effectively solving the problems of the electrical connector 210 being stuck and difficult to be subjected to the elastic force, and improving the conductive stability of the electrical connector 210. At the same time, the electrical connector 210 passes through the sheath 220 and is connected to the signal interface portion 110 on the circuit carrier 100 nearby through the wire 300, shortening the connection length of the wire 300, reducing the wire impedance brought by the wire 300, reducing the overall impedance of the conductive connection structure 10, and helping the conductive connection structure 10 as a whole to form a stable conductive circuit with the other electrical structures.

[0092] In some embodiments of this application, the electrical connector 210 can apply a holding force toward the circuit carrier 100 to the elastic member 230 under the support of the atomizing component.

[0093] Specifically, the atomizing component can be assembled inside the housing 500 and matched with the housing 500 in a limiting manner, such as by snap-fit ​​or threaded engagement.

[0094] Under the limiting action of the housing, the atomizing component maintains a state of abutting the electrical connector 210, so that the electrical connector 210 passively applies a pressing force toward the circuit carrier 100 to the elastic member 230. In this way, the elastic member 230's rebound force makes the electrical connector 210 and the corresponding part (positive contact or negative contact) of the atomizing component make tight contact, forming a stable electrical connection.

[0095] In some embodiments of this application, see Figure 9 and Figure 10The housing 500 has a partition 530 inside, which divides the cavity of the housing 500 into a first chamber 510 and a second chamber 520. The first chamber 510 is used to install the atomizing component, and the power supply unit 600 and the circuit carrier 100 are located in the second chamber 520. The partition 530 has a through hole 531 through which the power supply connector 210 passes.

[0096] Specifically, the housing 500 and the partition 530 are integrally formed, simplifying the molding process of both. The partition 530 divides the cavity of the housing 500 into a first chamber 510 and a second chamber 520 distributed vertically. The through hole 531 on the partition 530 is coaxial with the mounting hole 120 on the circuit carrier 100, providing clearance for the electrical connector 210 and avoiding structural interference between the partition 530 and the electrical connector 210.

[0097] The atomizing component can be installed in the first chamber 510 and, through a limiting engagement with the housing 500, abut against one end of the electrical connector 210 extending through the through hole 531 to form a stable electrical connection with the electrical connector 210.

[0098] In the above structure, the partition 530 can separate the atomizing component from the power supply unit 600 and the conductive connection structure 10 except for the electrical connector 210, so that the atomizing component is only in contact with the electrical connector 210, thereby further improving the conductivity stability and reliability of the electrical connector 210.

[0099] Further, see Figure 9 and Figure 10 The conductive connection structure 10 also includes a seal 400 located in the second chamber 520. The seal 400 is connected to the side of the circuit carrier 100 away from the power supply unit 600 and abuts against the partition 530.

[0100] Specifically, the seal 400 and the circuit carrier 100 are stacked together. The seal 400 has a clearance hole 410. The clearance hole 410, the electrical connector 210 and the electrical connector 210 are coaxial. The sheath 220 is clearance-fitted with the clearance hole 410 so that the seal 400 will not exert radial pressure on the sheath 220, thereby preventing the sheath 220 from deforming radially and interfering with the electrical connector 210.

[0101] The seal 400 can be an elastic insulator, such as a silicone seal or a rubber seal. The circuit carrier 100 can be fixed in the second chamber 520 by means of a snap-fit ​​structure, a threaded structure, etc., and presses the seal 400 toward the partition 530, so that the seal 400 elastically deforms to fill or cover the gap between the circuit carrier 100 and the partition 530.

[0102] Understandably, the above-described structure and the installation of the sealing element 400 can reduce the probability of aerosols in the first chamber 510 entering the second chamber 520, and provide protection and insulation for electrical structures such as the power supply unit 600 in the second chamber 520.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
