[0044] The Type-C interface is a hardware cable interface mainly used for data transmission and power supply to devices using this interface. The Type-C interface is small in size and convenient to use, making it widely used in electronic devices. Especially in aerosol production devices, the Type-C interface is used in conjunction with the charging module in the aerosol production device to charge the aerosol production device using the Type-C interface and also to perform data transmission with the aerosol production device. Among them, the charging module can refer to a combination of some electronic components in cooperation with the Type-C interface for charging.

[0045] However, after the Type-C interface is connected to the aerosol production device, a capacitor needs to be set on the charging module to eliminate some interference and improve the charging performance. But in some cases, especially in small-sized aerosol production devices (such as e-cigarettes, etc.), adding a capacitor to the charging module will increase the design difficulty or manufacturing difficulty of the charging module.

[0046] To solve the above problems, the embodiment of the present application provides a Type-C interface. A capacitor is integrated in the Type-C interface to filter and stabilize the power signal input to the Type-C interface by the capacitor, so as to eliminate signal interference and improve the charging performance. In addition, since the capacitor is provided in the Type-C interface, the design of the charging module can also be simplified.

[0047] The aerosol production device of the embodiment of the present application uses the Type-C interface as a charging interface and / or a data transmission interface. The aerosol production device can be, but is not limited to, an atomizer, an e-cigarette.

[0048] The following combines Figures 1 to 6 to describe the Type-C interface 1 and the aerosol production device of the embodiment of the present application.

[0049] As Figures 1 to 3 shown, in some embodiments of the present application, a Type-C interface 1 is provided. The Type-C interface 1 includes a housing 10 and a circuit structure 20; the circuit structure 20 is provided in the housing 10; the circuit structure 20 is provided in the housing 10; the circuit structure 20 includes a first negative electrode piece 201, a second negative electrode piece 202, a first positive electrode piece 203, and a second positive electrode piece 204. The first negative electrode piece 201 and the second negative electrode piece 202 are arranged at intervals along a first direction, and the first positive electrode piece 203 and the second positive electrode piece 204 are located between the first negative electrode piece 201 and the second negative electrode piece 202. Among them, the circuit structure 20 further includes a capacitor 205 located in the housing 10, and the capacitor 205 is electrically connected to the second negative electrode piece 202 and the second positive electrode piece 204.

[0050] The housing 10 can refer to a component with a hollow interior. The circuit structure 20 is disposed within the housing 10 to provide protection for the circuit structure 20. The housing 10 can be in a hollow tubular structure or can be flat to reduce the volume of the Type-c interface 1. Of course, it can also be of other shapes.

[0051] The circuit structure 20 can refer to the structure for conducting electricity in the Type-c interface 1. The circuit structure 20 includes a first negative electrode piece 201, a second negative electrode piece 202, a first positive electrode piece 203, and a second positive electrode piece 204. After the Type-c interface 1 is plugged into a power source, the first negative electrode piece 201 and the second negative electrode piece 202 are used to electrically connect to the positive electrode of the power source, and the first positive electrode piece 203 and the second positive electrode piece 204 are used to electrically connect to the positive electrode of the power source to achieve charging of the Type-c interface 1.

[0052] The first negative electrode piece 201, the second negative electrode piece 202, the first positive electrode piece 203, and the second positive electrode piece 204 are made of conductive materials, such as copper, aluminum, etc.; the materials of the first negative electrode piece 201, the second negative electrode piece 202, the first positive electrode piece 203, and the second positive electrode piece 204 can be the same or different. The shapes of the first negative electrode piece 201, the second negative electrode piece 202, the first positive electrode piece 203, and the second positive electrode piece 204 can be various: for example, linear, bent, wavy, etc. The shapes of the first negative electrode piece 201, the second negative electrode piece 202, the first positive electrode piece 203, and the second positive electrode piece 204 can be the same or different.

[0053] The first negative electrode piece 201 and the second negative electrode piece 202 are arranged at intervals in the first direction. The first positive electrode piece 203 and the second positive electrode piece 204 are located between the first negative electrode piece 201 and the second negative electrode piece 202. It can be understood that there is a certain space between the first negative electrode piece 201 and the second negative electrode piece 202, and this space is used to accommodate the first positive electrode piece 203 and the second positive electrode piece 204. Moreover, the first negative electrode piece 201 and the second negative electrode piece 202 do not contact the first positive electrode piece 203, and the first negative electrode piece 201 and the second negative electrode piece 202 do not contact the second positive electrode piece 204 to avoid short circuits.

[0054] Refer to Figure 1 As shown, the Type-c has a width direction, a length direction, and a thickness direction. The width direction of the Type-c interface 1 can refer to the X direction, the length direction of the Type-c interface 1 can refer to the Y direction, and the thickness direction of the Type-c interface 1 can refer to the Z direction. Among them, the first direction can refer to the width direction of the Type-c interface 1.

[0055] In some examples, the first negative electrode sheet 201, the first positive electrode sheet 203, the second positive electrode sheet 204, and the second negative electrode sheet 202 are arranged at intervals in sequence along the first direction, or the first negative electrode sheet 201, the second positive electrode sheet 204, the first positive electrode sheet 203, and the second negative electrode sheet 202 are arranged at intervals in sequence along the first direction. Such a distribution is beneficial to the distribution of components and reduces the volume of the Type-c interface 1. Of course, other arrangement methods are also possible.

[0056] The capacitor 205 may refer to an electronic component used for storing electrical energy, which is composed of a layer of insulating material (referred to as a dielectric) sandwiched between two conductors (usually metal plates). When the capacitor 205 is connected to a circuit, it can store electric charges and release these charges when needed. The basic working principle of the capacitor 205 is to use an electric field to store energy. The capacitor 205 can be used for filtering, coupling, decoupling, timing, energy storage, etc. The capacitor 205 can be, but is not limited to, a ceramic capacitor 205, an electrolytic capacitor 205, a thin film capacitor 205, a mica capacitor 205.

[0057] The capacitor 205 is electrically connected to the second negative electrode sheet 202 and the second positive electrode sheet 204. It can be understood that one end of the capacitor 205 is electrically connected to the second negative electrode sheet 202, and the other end of the capacitor 205 is electrically connected to the second positive electrode sheet 204. Among them, in the embodiments of the present application, "electrically connected" may refer to the electrical connection between two components through a wire, or may refer to the way of realizing electrical conduction between two components through welding, bonding, etc. Of course, it may also refer to other ways.

[0058] In the Type-c interface 1 of the embodiments of the present application, when in use, a power supply is inserted into the Type-c interface 1, so that the power supply is electrically connected to the first positive electrode sheet 203, the second positive electrode sheet 204, the first negative electrode sheet 201, and the second negative electrode sheet 202, thereby realizing charging; and a capacitor 205 is provided in the housing 10, and the capacitor 205 is electrically connected to the second negative electrode sheet 202 and the second positive electrode sheet 204, so that the Type-c interface 1 can filter, stabilize the voltage, and eliminate interference on the input power supply signal, improving the charging performance of the Type-c interface 1; in addition, the capacitor 205 is integrated in the Type-c interface 1, which can also reduce the design difficulty of the charging module 21 and improve the versatility of the Type-c interface 1.

[0059] In some embodiments, refer to Figure 1 As shown, the housing 10 may be provided with pins 11 to facilitate the fixation of the Type-c interface 1, or the housing 10 may not be provided with pins 11 to meet the fixation requirements of other methods.

[0060] In some embodiments, refer to Figure 3 and Figure 4As shown, the circuit structure 20 further includes a first CC piece 206 and a second CC piece 207 for determining the direction of the power supply inserted into the Type-c interface 1.

[0061] In some other embodiments of the present application, refer to Figure 1 and Figure 2 As shown, the Type-c interface 1 further includes an insulating member 30 disposed in the housing 10. The insulating member 30 covers the outside of the circuit structure 20, and the insulating member 30 and the circuit structure 20 are an integrally injection-molded structure.

[0062] It can be understood that the insulating member 30 and the circuit structure 20 can be an integrally injection-molded structure obtained by an integrally injection-molding process. For example, the circuit structure 20 is placed in a mold, and then an insulating material is injected into the mold. After the insulating material is cured, an integrally injection-molded structure is obtained. Among them, the insulating member 30 is obtained after the insulating material is cured, and the insulating member 30 covers the outside of the circuit structure 20. At the same time, the gaps in the circuit structure 20 are filled with insulating materials. In this way, after the insulating member 30 is installed in the housing 10, insulation between the circuit structure 20 and the housing 10 can be achieved, and insulation within the circuit structure 20 can also be achieved. A space for inserting the power supply is formed between the insulating member 30 and a part of the inner wall of the housing 10. Part of the surfaces of the first positive electrode piece 203, the second positive electrode piece 204, the first negative electrode piece 201, the second negative electrode piece 202, the first CC piece 206, and the second CC piece 207 are exposed outside the insulating member 30 to facilitate electrical connection with the power supply and achieve charging and / or data transmission.

[0063] By adopting the technical solution of this embodiment, the insulating member 30 can achieve insulation between the circuit structure 20 and the housing 10. At the same time, the insulating member 30 and the circuit structure 20 adopt an integrally injection-molding process, and its manufacturing process is simple, which is beneficial to reducing the manufacturing cost.

[0064] In some other embodiments of the present application, refer to Figure 2 、 Figure 3 and Figure 4 As shown, the first negative electrode piece 201 is electrically connected to the second negative electrode piece 202, and one end of the first negative electrode piece 201 or one end of the second negative electrode piece 202 protrudes from the housing 10 and forms a negative terminal 201a; the first positive electrode piece 203 and the second positive electrode piece 204 are electrically connected, and one end of the first positive electrode piece 203 or one end of the second positive electrode piece 204 protrudes outside the housing 10 and forms a positive terminal 204a.

[0065] The first negative electrode sheet 201 and the second negative electrode sheet 202 are electrically connected. It can be understood that the first negative electrode sheet 201 and the second negative electrode sheet 202 are directly connected, or the first negative electrode sheet 201 and the second negative electrode sheet 202 can be electrically connected through the negative electrode conductive member 212, so that the first negative electrode sheet 201 and the second negative electrode sheet 202 can be combined. In this way, a negative terminal 201a can be led out, so that the end of the first negative electrode sheet 201 protruding from the housing 10 can be used as the negative terminal 201a, or the end of the second negative electrode sheet 202 protruding from the housing 10 can be used as the negative terminal 201a. With such a design, the structure of the circuit structure 20 is simple.

[0066] In some examples, the first negative electrode sheet 201, the second negative electrode sheet 202 and the negative electrode conductive member 212 can be integrally formed components. For example: the first negative electrode sheet 201, the second negative electrode sheet 202 and the negative electrode conductive member 212 are integrally formed by a casting process. The first negative electrode sheet 201, the second negative electrode sheet 202 and the negative electrode conductive member 212 can also be separately formed and then connected to each other as a whole. For example, the first negative electrode sheet 201 is welded or clamped to one end of the negative electrode conductive member 212, and the second negative electrode sheet 202 is welded or clamped to the other end of the negative electrode conductive member 212.

[0067] The first positive electrode sheet 203 and the second positive electrode sheet 204 are electrically connected. It can be understood that the first positive electrode sheet 203 and the second positive electrode sheet 204 are directly connected, or the first positive electrode sheet 203 and the second positive electrode sheet 204 can be electrically connected through the positive electrode conductive member 213, so that the first positive electrode sheet 203 and the second positive electrode sheet 204 can be combined. In this way, a positive terminal 204a can be led out, so that the end of the first negative electrode sheet 201 protruding from the housing 10 can be used as the positive terminal 204a, or the end of the second positive electrode sheet 204 protruding from the housing 10 can be used as the positive terminal 204a. With such a design, the structure of the circuit structure 20 is simple.

[0068] In some examples, the first positive electrode sheet 203, the second positive electrode sheet 204 and the positive electrode conductive member 213 can be integrally formed components. For example: the first positive electrode sheet 203, the second positive electrode sheet 204 and the positive electrode conductive member 213 are integrally formed by a casting process. The first positive electrode sheet 203, the second positive electrode sheet 204 and the positive electrode conductive member 213 can also be separately formed and then connected to each other as a whole. For example, the first positive electrode sheet 203 is welded or clamped to one end of the positive electrode conductive member 213, and the second positive electrode sheet 204 is welded or clamped to the other end of the positive electrode conductive member 213.

[0069] The positive terminal 204a and the negative terminal 201a can be located on the same side of the Type-c interface 1 to facilitate the electrical connection of the Type-c interface 1. In other examples, the positive terminal 204a and the negative terminal 201a can be located on different sides of the Type-c interface 1.

[0070] In some examples, when the first negative electrode sheet 201, the first positive electrode sheet 203, the second positive electrode sheet 204, and the second negative electrode sheet 202 are arranged at intervals in sequence, the end of the first negative electrode sheet 201 protruding from the housing 10 can be used as the negative terminal 201a, and the end of the second positive electrode sheet 204 protruding from the housing 10 can be used as the positive terminal 204a. Alternatively, the end of the second negative electrode sheet 202 protruding from the housing 10 can be used as the negative terminal 201a, and the end of the first negative electrode sheet 201 protruding from the housing 10 can be used as the positive terminal 204a. The distance between the positive terminal 204a and the negative terminal 201a is far, which can reduce the risk of short circuit.

[0071] By adopting the technical solution of this embodiment, the Type-c interface 1 leads out a positive terminal 204a and a negative terminal 201a. These two terminals can be directly welded to the charging module 21 or can meet the application of being surface-mounted on the charging module 21, improving the versatility of the Type-c interface 1; it also avoids complex leads, reduces the assembly difficulty, has a simple structure and preparation process, improves the processing efficiency, and reduces the production cost; in addition, directly using the end of the negative electrode sheet or the end of the positive electrode sheet as the terminal makes the structure of the Type-c interface 1 simpler and the cost lower.

[0072] In some other embodiments of the present application, refer to Figure 3 As shown, the circuit structure 20 further includes a negative electrode conductive member 212. The negative electrode conductive member 212 includes a first connection portion 2121, a second connection portion 2122, and a third connection portion 2123.

The first direction is perpendicular to the second direction; the third connection portion 2123 is disposed close to the negative terminal 201a and is spaced from the first positive electrode sheet 203 and the second positive electrode sheet 204.

[0073] The negative electrode conductive member 212 may refer to a component made of a conductive material, such as copper, aluminum, etc. The negative electrode conductive member 212 has a U-shaped structure. The parts of the negative electrode conductive member 212 located on both sides are the first connection portion 2121 and the second connection portion 2122 respectively, and the part connecting the first connection portion 2121 and the second connection portion 2122 is the third connection portion 2123; the first connection portion 2121 and the first negative electrode sheet 201 can be electrically connected by welding, clamping, fitting, etc., and the second connection portion 2122 and the second negative electrode sheet 202 can be electrically connected by welding, clamping, etc.

[0074] The second direction may refer to a direction perpendicular to the first direction. Specifically, reference may be made to the thickness direction of the Type-c interface 1. The first connecting portion 2121 and the first negative electrode piece 201 are stacked and bonded together in the second direction, and the second connecting portion 2122 and the second negative electrode piece 202 are stacked and bonded together in the second direction. This can reduce the size of the Type-c interface 1 in the first direction and make full use of the space of the Type-c interface 1 in the second direction, which is beneficial to the miniaturization of the Type-c interface 1. In addition, the first connecting portion 2121 and the second connecting portion 2122 can also stably support the first negative electrode piece 201 and the second negative electrode piece 202, improving the reliability of electrical connection.

[0075] The third connecting portion 2123 is connected between the end of the first connecting portion 2121 close to the negative terminal 201a and the end of the second connecting portion 2122 close to the negative terminal 201a. This is beneficial to reducing the size of the Type-c interface 1 in the length direction, making full use of the space inside the Type-c interface 1, and being beneficial to the miniaturization of the Type-c interface 1.

[0076] The third connecting portion 2123 is arranged at intervals from the first positive electrode piece 203, and the third connecting portion 2123 is arranged at intervals from the second positive electrode piece 204. It may mean that the third connecting portion 2123 does not contact the first positive electrode piece 203 and the second positive electrode piece 204, thereby reducing the risk of short circuit.

[0077] In some examples, it may be that the first connecting portion 2121 and the second connecting portion 2122 are bent, so that the third connecting portion 2123, the first positive electrode piece 203, and the second positive electrode piece 204 are offset in the thickness direction of the Type-c interface 1; it may also be that the third connecting portion 2123 is recessed to avoid the first positive electrode piece 203 and the second positive electrode piece 204.

When the first convex portion 201b is inserted into the first groove 2121a, the relative fixation between the two components can be restricted. The shape of the first groove 2121a is adapted to that of the first convex portion 201b to better connect the first negative electrode sheet 201 and the first connection portion 2121; wherein, the first groove 2121a may extend along the length direction of the Type-c interface 1, and the lengths of the first convex portion 201b and the first groove 2121a are long to better connect the first negative electrode sheet 201 and the first connection portion 2121; of course, it may also extend in other directions. The first groove 2121a may penetrate the component or may not penetrate the component. Similarly, the second groove 2122a may adopt the same structure as the first groove 2121a. Of course, the second groove 2122a may also adopt other structures.

[0082] In some examples, the first negative electrode sheet 201 is provided with a first convex portion 201b, and the first connection portion 2121 is provided with a first groove 2121a for inserting the first convex portion 201b; or, the first negative electrode sheet 201 is provided with a first convex portion 201b, and the first connection portion 2121 is provided with a first groove 2121a for inserting the first convex portion 201b; through the insertion and cooperation of the first convex portion 201b and the first groove 2121a, the fixation between the negative electrode conductive member 212 and the first connection portion 2121 is more reliable, which is also beneficial to improving the reliability of the position of the first negative electrode sheet 201 during subsequent injection molding. Moreover, the structure is simple and the volume is small, which is beneficial to the miniaturization of the Type-c interface 1.

Moreover, the structure is simple and the volume is small, which is beneficial to the miniaturization of the Type-c interface 1.

[0084] By adopting the technical solution of this embodiment, the negative electrode conductive member 212 has a good supporting and fixing effect on the first negative electrode sheet 201 and the second negative electrode sheet 202, which is beneficial to improving the injection molding accuracy of the subsequent Type-c interface 1 and increasing the yield rate and structural strength of the Type-c interface 1.

[0088] In some cases, when the Type-c interface 1 is used as the output port of the PD protocol (Power Delivery) adapter, the Type-c interface 1 has no voltage output by default, and the Type-c interface 1 itself cannot open the PD protocol adapter. Two CC chips (CC chips are also terminals for connection confirmation) must be set in the Type-c interface 1, and chip resistors (for example, 5.1KΩ chip resistors) need to be welded between the two CC chips and the negative terminal 201a, so that the PD protocol adapter can output a voltage of 5V. However, the Type-c interface 1 that needs to be transferred is welded on the PCB substrate (printed circuit board), the resistor is welded on the PCB substrate, and then the chip resistor, CC chip and negative terminal 201a are electrically connected by wires to open the PD protocol adapter. This manufacturing process is relatively complicated, costly and large in size.

After the power supply is inserted into the Type-c interface 1, the power supply contacts the first CC sheet 206 and the second CC sheet 207, so as to determine the direction of the power supply in the Type-c interface 1 to facilitate subsequent charging. The shapes of the first CC sheet 206 and the second CC sheet 207 can refer to multiple shapes, such as straight line, L-shape or wavy shape.
