[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0021] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.
[0022] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position 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, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.
[0024] Currently, with the increasing variety of beauty devices on the market, users' demands for intelligent features in these devices are also rising. Consequently, there are more and more scenarios requiring firmware configuration or upgrades for beauty devices.
[0025] As an example, to reduce the number of external interfaces on a beauty device, it typically only has one power supply interface. Therefore, configuring or upgrading the firmware requires disassembling the device, making the process overly cumbersome.
[0026] In other examples, while wireless communication modules, such as Bluetooth, UHF, or Wi-Fi modules, can be incorporated into the beauty device for firmware configuration or upgrades via over-the-air (OTA) firmware downloads, this can easily increase the cost of the device and also add complexity to its internal circuitry.
[0027] To address the aforementioned technical problems, this application provides a control circuit for a beauty device, including a control unit, an isolation unit, and an energy output unit. The control unit outputs a first control signal and a second control signal. The isolation unit is connected to the contact electrodes of the beauty device and is also connected to the control unit. The isolation unit transmits the electrical signal input through the contact electrodes to the control unit, and disconnects the path between the contact electrodes and the control unit upon receiving the first control signal. Here, the electrical signal is output from an external device connected to the contact electrodes. The energy output unit is connected to both the contact electrodes and the control unit. The energy output unit generates electrical energy according to the second control signal and outputs the electrical energy to the contact electrodes.
[0028] The above solution achieves the reuse of the contact electrodes by connecting an isolation unit between the contact electrodes and the control unit of the beauty device. When an external device inputs an electrical signal through the contact electrodes, the isolation unit can transmit the input signal to the control unit for firmware configuration or upgrades. Alternatively, the isolation unit can disconnect the path between the contact electrodes and the control unit upon receiving a first control signal. The energy output unit generates electrical energy based on a second control signal and outputs it to the contact electrodes. Thus, the electrical energy is applied to the user's skin through the contact electrodes. This ensures the normal operation of the beauty device while enabling firmware configuration or upgrades without disassembling the device, simplifying the process.
[0029] Furthermore, it eliminates the need for a dedicated wireless communication module in the beauty device. By reusing contact electrodes to transmit electrical signals to the control unit, firmware configuration or upgrades can be performed on the beauty device. This reduces the implementation cost of the beauty device and avoids increasing the complexity of its internal circuitry.
[0030] See Figure 1 , Figure 1 A schematic diagram of the control circuit of a beauty device according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:
[0031] exist Figure 1In the beauty device, the control circuit 100 includes: a control unit 10, an isolation unit 20, and an energy output unit 30. Specifically, as shown... Figure 1 As shown, the beauty device is equipped with contact electrodes 110. A control unit 10 outputs a first control signal and a second control signal. An isolation unit 20 is connected to both the contact electrodes 110 and the control unit 10. This isolation unit 20 transmits the electrical signal input through the contact electrodes 110 to the control unit 10, and disconnects the path between the contact electrodes 110 and the control unit 10 upon receiving the first control signal. The electrical signal is output from an external device connected to the contact electrodes 110. An energy output unit 30, connected to both the contact electrodes 110 and the control unit 10, generates electrical energy according to the second control signal and outputs the electrical energy to the contact electrodes 110.
[0032] In this embodiment, "external device" generally refers to a device that outputs electrical signals to the control circuit 100 via the contact electrode 110. For example, the external device can be a configuration board composed of a microcontroller and / or a host computer. Here, "electrical signal" refers to the electrical signal transmitted during firmware configuration or firmware upgrade of the control circuit 100 using the external device via the contact electrode 110. It is easy to understand that the contact electrode 110 generally refers to the electrode on the beauty device used to output electrical energy to the skin. Based on this, when configuring or upgrading the firmware of the beauty device, the external device is connected to the contact electrode 110, and the external device can output electrical signals for firmware configuration or firmware upgrade to the contact electrode 110.
[0033] In a practical implementation, an external device can form a path for transmitting electrical signals by setting a metal electrode, metal pin, or metal contact that cooperates with the contact electrode 110 and making contact with the contact electrode 110.
[0034] For example, an external device can be equipped with a metal electrode corresponding to the contact electrode 110. In actual use, the metal electrode can be configured as a magnetic electrode and magnetically connected to the contact electrode 110 to form a path for transmitting electrical signals.
[0035] For example, external devices can be equipped with metal contacts corresponding to the contact electrode 110. In actual use, the metal contacts can be configured as grooved electrodes that are compatible with the contact electrode 110 and snap into the contact electrode 110 to form a path for transmitting electrical signals.
[0036] In all embodiments of this application, the isolation unit 20 is configured to open the path between the contact electrode 110 and the control unit 10 by default. When configuring or upgrading the firmware of the beauty device, an external device is connected to the contact electrode 110. The external device can output an electrical signal for firmware configuration or upgrade to the contact electrode 110, which can be sent to the control unit 10 via the isolation unit 20. When using the beauty device, the control unit 10 in the control circuit 100 can output a first control signal to the isolation unit 20 and a second control signal to the energy output unit 30. At this time, the energy output unit 30 generates electrical energy according to the second control signal and outputs the electrical energy to the contact electrode 110. When the contact electrode 110 comes into contact with the skin, the electrical energy is conducted to the skin, thereby achieving the effect of skin care. Simultaneously, the isolation unit 20 disconnects the path between the contact electrode 110 and the control unit 10 according to the first control signal, preventing the electrical energy output by the energy output unit 30 from being transmitted through the path formed by the contact electrode 110, the isolation unit 20, and the control unit 10. That is, when the energy output unit 30 outputs electrical energy, because the isolation unit 20 disconnects the path between the contact electrode 110 and the control unit 10, the electrical energy will not affect or interfere with the control unit 10.
[0037] For example, in a specific implementation, the isolation unit 20 can be implemented using an isolation chip or a relay. For instance, the isolation unit 20 includes an isolation chip that, by default, keeps the path between the contact electrode 110 and the control unit 10 open when no first control signal is received, and disconnects the path when the first control signal is received. Here, since the electrical energy output through the contact electrode 110 during actual use of the beauty device is a high-voltage, high-frequency AC signal, the isolation chip should be selected to isolate high-frequency AC power.
[0038] As an example, assuming the frequency of electrical energy can be from 0.5 MHz to 2.5 MHz, the isolation chip can specifically be an isolation chip capable of isolating 10 MHz electrical signals.
[0039] As an example, the energy output unit 30 may specifically be an EMS output unit and / or a radio frequency output unit.
[0040] In one example, when the energy output unit 30 can be an EMS output unit, the EMS output unit can generate an EMS current according to the second control signal, and output the EMS current as electrical energy to the contact electrode.
[0041] In another example, when the energy output unit 30 can be a radio frequency output unit, the radio frequency output unit can generate a radio frequency current according to the second control signal, and output the radio frequency current as electrical energy to the contact electrode.
[0042] In other examples, when the energy output unit 30 may include an EMS output unit and a radio frequency (RF) output unit, and the energy output unit 30 generates electrical energy according to the second control signal and outputs electrical energy to the contact electrode 110, specifically, the EMS output unit and the RF output unit may alternately output EMS current and RF current. Alternatively, the EMS output unit and the RF output unit may simultaneously output EMS current and RF current, respectively.
[0043] The above solution achieves contact electrode reuse by connecting an isolation unit between the contact electrodes and the control unit of the beauty device. That is, when an external device inputs an electrical signal through the contact electrodes, the isolation unit can transmit the input signal to the control unit for firmware configuration or upgrades. Alternatively, the isolation unit can disconnect the path between the contact electrodes and the control unit upon receiving a first control signal. The energy output unit generates electrical energy based on a second control signal and outputs it to the contact electrodes. Thus, the electrical energy is applied to the user's skin through the contact electrodes. This ensures normal use of the beauty device while enabling firmware configuration or upgrades without disassembling the device, simplifying the process.
[0044] Figure 2 A schematic diagram of the control circuit of a beauty device provided in an embodiment of this application is shown. Figure 2 As shown in the figure, as an embodiment, the isolation unit 20 includes a first connection terminal 211, a second connection terminal 212, and a controlled terminal 213. The first connection terminal 211 is connected to the communication terminal of the control unit 10, the second connection terminal 212 is used to connect to the contact electrode 110, and the controlled terminal 213 is connected to the first output terminal of the control unit 10.
[0045] In this embodiment, the isolation unit 20 is specifically used to disconnect the path between the first connection terminal 211 and the second connection terminal 212 when the first control signal is received through the controlled terminal 213, and to connect the path between the first connection terminal 211 and the second connection terminal 212 when the first control signal is not received.
[0046] It is understood that the first connection terminal 211 and the second connection terminal 212 of the isolation unit 20 can be connected through an internal structure. Here, the connection path between the first connection terminal 211 and the second connection terminal 212 can be considered as a switch connected in series. When the isolation unit 20 does not receive the first control signal, the switch is closed, meaning the path between the first connection terminal 211 and the second connection terminal 212 is conductive. When the isolation unit 20 receives the first control signal through the controlled terminal 213, it controls the switch to open, thus disconnecting the path between the first connection terminal 211 and the second connection terminal 212.
[0047] Therefore, in specific implementation, the isolation unit 20 can be implemented using a switching circuit composed of switching transistors, or using an existing electronic switch.
[0048] As an example, the isolation unit 20 can be implemented using a switching circuit composed of switching transistors, which includes an input terminal, an output terminal, and a controlled terminal. The input terminal of the switching circuit serves as the second connection terminal 212 of the isolation unit 20, the output terminal serves as the first connection terminal 211 of the isolation unit 20, and the controlled terminal serves as the controlled terminal 213 of the isolation unit 20. In a specific implementation, the control unit 10 can input a first control signal to the controlled terminal of the switching circuit, thereby controlling the switching circuit to disconnect, that is, breaking the connection between the input and output terminals of the switching circuit.
[0049] As another example, the isolation unit 20 can also be implemented using an existing electronic switch. Here, the electronic switch can be connected in series between the contact electrode 110 and the electrical signal input terminal of the control unit 10, and the electronic switch is controlled by the control unit 10. When using the beauty device to care for the skin, the control unit 10 can control the electronic switch to turn off by outputting a first control signal, and at the same time output a second control signal to instruct the energy output unit 30 to output electrical energy. When configuring or upgrading the firmware of the beauty device, the electronic switch opens the path between the contact electrode 110 and the control unit 10. The external device inputs an electrical signal through the contact electrode 110, and the electrical signal is transmitted to the control unit 10 through this path, providing an electrical signal transmission path for configuring or upgrading the firmware of the beauty device.
[0050] Figure 3 This application illustrates the specific circuit of the isolation unit in the control circuit of a beauty device according to an embodiment of the present application. Figure 1 .like Figure 3 As shown, in one embodiment, the contact electrode 110 includes at least a first contact electrode 111 and a second contact electrode 112 disposed at a distance from each other. Correspondingly, the isolation unit 20 includes an isolation chip U20.
[0051] exist Figure 3In the isolation chip U20, there are at least a first communication terminal I / O1, a second communication terminal I / O2, a third communication terminal I / O3, a fourth communication terminal I / O4 and an input terminal IN. The first communication terminal I / O1 is connected to the first contact electrode 111, the second communication terminal I / O2 is connected to the second contact electrode 112, the third communication terminal I / O3 and the fourth communication terminal I / O4 are respectively connected to the control unit 10, and the input terminal IN serves as the controlled terminal 213 of the isolation unit 20.
[0052] In this embodiment, the first communication terminal I / O1 and the third communication terminal I / O3 of the isolation chip U20 are respectively used to connect the first contact electrode 111 and the second contact electrode 112, and the second communication terminal I / O2 and the fourth communication terminal I / O4 of the isolation chip U20 are respectively used to connect the first configuration terminal 11 and the second configuration terminal 12 of the control unit 10. Since the input terminal IN of the isolation chip U20 is connected to the first output terminal 13 of the control unit 10, the control unit 10 can output a first control signal to the input terminal IN of the isolation chip U20 through the first output terminal 13.
[0053] like Figure 3 As shown, in the isolation chip U20, the path between the first communication terminal I / O1 and the third communication terminal I / O3 can be considered as a series connection of the first switch S1. Similarly, the path between the second communication terminal I / O2 and the fourth communication terminal I / O4 can be considered as a series connection of the second switch S2.
[0054] In all examples of this application, when using a beauty device to care for the skin, it is necessary to utilize the control circuit 100 to output electrical energy to act on the skin. Figure 1 and Figure 3 The control unit 10 outputs a first control signal to the isolation unit 20 and a second control signal to the energy output unit 30 at the same time.
[0055] Combination Figure 3 For example, the control unit 10 outputs a first control signal to the input terminal IN of the isolation chip U20 through the first output terminal 13. According to the first control signal, the isolation chip U20 controls the first switch S1 and the second switch S2 to disconnect. At this time, the path between the first contact electrode 111 and the first configuration terminal 11 of the control unit 10 is disconnected, and the path between the second contact electrode 112 and the second configuration terminal 12 of the control unit 10 is disconnected, that is, the path between the contact electrode 110 and the control unit 10 is disconnected.
[0056] For example, in combination Figure 1 and Figure 3It is understood that the control unit 10 may also include a second output terminal (not shown in the figure). The control unit 10 can be connected to the energy output unit 30 through this second output terminal, and then output a second control signal to the energy output unit 30. The energy output unit 30 generates electrical energy according to the second control signal and outputs electrical energy to the contact electrode 110. For example, it alternately outputs EMS current to the first contact electrode 111 and the second contact electrode 112. Or, it alternately outputs radio frequency current to the first contact electrode 111 and the second contact electrode 112. At this time, although the first communication terminal I / O1 and the second communication terminal I / O2 of the isolation chip U20 are connected to the first contact electrode 111 and the second contact electrode 112 respectively, the first switch S1 and the second switch S2 are open at this time. The electrical energy applied by the energy output unit 30 to the first contact electrode 111 and / or the second contact electrode 112 cannot be transmitted to the control unit 10 through the isolation chip U20. That is, when electrical energy is applied to the skin through the contact electrode 110, the electrical energy is prevented from being transferred to the control unit 10 through the path between the contact electrode 110 and the control unit 10.
[0057] Figure 4 This application illustrates the specific circuit of the isolation unit in the control circuit of a beauty device according to an embodiment of the present application. Figure 2 .like Figure 4 As shown, in one embodiment, the contact electrode 110 includes at least a first contact electrode 111 and a second contact electrode 112 disposed at a distance from each other. Correspondingly, the isolation unit 20 includes a first isolation chip U1 and a second isolation chip U2.
[0058] In this embodiment, the first communication terminal I / O1 of the first isolation chip U1 is used to connect to the first contact electrode 111, the second communication terminal I / O2 of the first isolation chip U1 is used to connect to the control unit 10, the first communication terminal I / O1 of the second isolation chip U2 is used to connect to the second contact electrode 112, the second communication terminal I / O2 of the second isolation chip U2 is used to connect to the control unit 10, the first input terminal IN1 of the first isolation chip U1 is connected to the second input terminal IN2 of the second isolation chip, and the node P formed serves as the controlled terminal 213 of the isolation unit 20.
[0059] In some embodiments, the first input terminal IN1 of the first isolation chip U1 and the second input terminal IN2 of the second isolation chip can be used together as the controlled terminal 213 of the isolation unit 20 and connected to the first output terminal 13 of the control unit 10.
[0060] In practical implementation, the first isolation chip U1 and the second isolation chip U2 can be implemented using isolation chips of the same specifications or model. Here, with Figure 3Similar to the isolation chip U20, in the first isolation chip U1, the path between the first communication terminal I / O1 and the second communication terminal I / O2 can be considered as a series connection of the first switch S1. Similarly, in the second isolation chip U2, the path between the first communication terminal I / O1 and the second communication terminal I / O2 can be considered as a series connection of the second switch S2.
[0061] When using a beauty device for skin care, the control circuit 100 outputs electrical energy to act on the skin. Combined with... Figure 1 and Figure 4 The control unit 10 outputs a first control signal to the isolation unit 20 and a second control signal to the energy output unit 30 at the same time.
[0062] Combination Figure 4 For example, control unit 10 outputs a first control signal to node P through first output terminal 13. Alternatively, control unit 10 outputs a first control signal to the first input terminal IN1 of first isolation chip U1 and the second input terminal IN2 of second isolation chip through first output terminal 13. Based on the first control signal, first isolation chip U1 controls first switch S1 to open, and second isolation chip U2 controls second switch S2 to open. At this time, the path between first contact electrode 111 and first configuration terminal 11 of control unit 10 is disconnected, and the path between second contact electrode 112 and second configuration terminal 12 of control unit 10 is disconnected, thus achieving the disconnection of the path between contact electrode 110 and control unit 10.
[0063] For example, in combination Figure 1 and Figure 4 It is understood that the control unit 10 may also include a second output terminal (not shown in the figure). The control unit 10 can be connected to the energy output unit 30 through this second output terminal, and then output a second control signal to the energy output unit 30. The energy output unit 30 generates electrical energy according to the second control signal and outputs electrical energy to the contact electrode 110. For example, it alternately outputs EMS current to the first contact electrode 111 and the second contact electrode 112. Or, it alternately outputs radio frequency current to the first contact electrode 111 and the second contact electrode 112. At this time, although the first isolation chip U1 and the second isolation chip U2 are connected to the first contact electrode 111 and the second contact electrode 112 respectively, the first switch S1 and the second switch S2 are open at this time. The electrical energy applied by the energy output unit 30 to the first contact electrode 111 and / or the second contact electrode 112 cannot be transmitted to the control unit 10 through the first isolation chip U1 and / or the second isolation chip U2. That is, when electrical energy is applied to the skin through the contact electrode 110, the electrical energy is prevented from being transferred to the control unit 10 through the path between the contact electrode 110 and the control unit 10.
[0064] Figure 5 This application illustrates the specific circuit of the isolation unit in the control circuit of a beauty device according to an embodiment of the present application. Figure 3 .like Figure 5 As shown, in one embodiment, the contact electrode 110 includes at least a first contact electrode 111 and a second contact electrode 112 spaced apart. Correspondingly, the isolation unit 20 includes a relay D1.
[0065] In this embodiment, the first detection terminal DETC1 of relay D1 is connected to the first contact electrode 111, the second detection terminal DETC2 of relay D1 is connected to the second contact electrode 112, the first common terminal COM1 and the second common terminal COM2 of relay D1 are respectively connected to the control unit 10, and the power input terminal VDD of relay D1 serves as the controlled terminal 213 of isolation unit 20.
[0066] As an example, relay D1 can specifically be a normally closed relay. Correspondingly, the first detection terminal DETC1 is the first normally closed terminal DETC1 of the normally closed relay, and the second detection terminal DETC2 is the second normally closed terminal DETC2 of the normally closed relay. Here, the normally closed relay is used to disconnect the connection between the first normally closed terminal DETC1 and the first common terminal COM1, and to disconnect the connection between the second normally closed terminal DETC2 and the second common terminal COM1, when a first control signal is input to the power input terminal VDD.
[0067] Here, with Figure 3 Similar to the isolation chip U20, in relay D1, the path between the first detection terminal DETC1 and the first common terminal COM1 can be considered as a series connection of the first switch S1. Similarly, the path between the second detection terminal DETC2 and the second common terminal COM2 can be considered as a series connection of the second switch S2.
[0068] When using a beauty device for skin care, the control circuit 100 outputs electrical energy to act on the skin. Combined with... Figure 1 and Figure 5 The control unit 10 outputs a first control signal to the isolation unit 20 and a second control signal to the energy output unit 30 at the same time.
[0069] Combination Figure 5For example, the control unit 10 outputs a first control signal to the power input terminal VDD of the relay D1 through the first output terminal 13. Based on this first control signal, the relay D1 controls the first switch S1 to open and the second switch S2 to open. At this time, the path between the first contact electrode 111 and the first configuration terminal 11 of the control unit 10 is broken, and the path between the second contact electrode 112 and the second configuration terminal 12 of the control unit 10 is broken, thus disconnecting the path between the contact electrode 110 and the control unit 10.
[0070] For example, in combination Figure 1 and Figure 5 It is understood that the control unit 10 may also include a second output terminal (not shown in the figure). The control unit 10 can be connected to the energy output unit 30 through this second output terminal, and then output a second control signal to the energy output unit 30. The energy output unit 30 generates electrical energy according to the second control signal and outputs electrical energy to the contact electrode 110. For example, it alternately outputs EMS current to the first contact electrode 111 and the second contact electrode 112. Or, it alternately outputs radio frequency current to the first contact electrode 111 and the second contact electrode 112. At this time, although the relay D1 is connected to the first contact electrode 111 and the second contact electrode 112, the first switch S1 and the second switch S2 are disconnected. The electrical energy applied by the energy output unit 30 to the first contact electrode 111 and / or the second contact electrode 112 cannot be transmitted to the control unit 10 through the relay D1. That is, when electrical energy is output through the contact electrode 110 and applied to the skin, the electrical energy is prevented from being transmitted to the control unit 10 through the path between the contact electrode 110 and the control unit 10.
[0071] The above solution configures a relay D1 in the isolation unit 20. Since the relay D1 can disconnect the connection between the first normally closed terminal DETC1 and the first common terminal COM1 when powered on, and disconnect the connection between the second normally closed terminal DETC2 and the second common terminal COM1, it has a withstand voltage of over 1000V and an isolation frequency of over 10 MHz. It also has high withstand voltage and signal isolation capabilities. While reusing the contact electrodes to transmit electrical signals to the control unit, it can better ensure the normal use of the beauty device and improve the stability of the beauty device.
[0072] Figure 6 A schematic diagram of the structure of a beauty device provided in an embodiment of this application is shown. Figure 6 As shown, the beauty device 200 includes the control circuit 100 of the beauty device provided in the above solution.
[0073] Understandably, in Figure 6 In the embodiments shown, due to the improvements and specific implementation methods related to this application, [the following has been implemented]. Figures 1 to 5 The corresponding embodiments are described in detail, so they will not be repeated here.
[0074] Figure 7 A schematic diagram of the configuration system of a beauty device according to an embodiment of this application is shown. Figure 7 As shown, the configuration system 400 of the beauty device includes an external device 300 and the beauty device 200 provided in the above solution.
[0075] Figure 8 This illustration shows a schematic diagram of a specific configuration system for a beauty device according to an embodiment of this application. For example... Figure 8 As shown, in one embodiment, in the configuration system 400 of the beauty device, the beauty device 200 is configured with a first connecting part (not shown in the figure).
[0076] In this embodiment, the external device 300 includes a host computer 310 and a connection component 320. The host computer 310 provides electrical signals. The connection component 320 is connected to the host computer 310.
[0077] In a specific implementation, the connecting assembly 320 may be equipped with a connecting electrode 321, which corresponds to the contact electrode 110 in the beauty device 200. The connecting assembly 320 may also be equipped with a second connecting portion (not shown in the figure). This second connecting portion is used to cooperate with the first connecting portion to bring the connecting electrode 321 into contact with the contact electrode 110.
[0078] For example, the first connecting portion and the second connecting portion can be mutually cooperating connection structures. For instance, the first connecting portion can be a protrusion with an irregular structure, and the second connecting portion can be a groove that matches the protrusion. Alternatively, the first connecting portion can be a plug-in, and the second connecting portion can be a snap-fit hole that matches the plug-in. When the connecting assembly 320 contacts the beauty device 200, the second connecting portion cooperates with the first connecting portion, causing the connecting assembly 320 and the beauty device 200 to adhere to each other, thereby bringing the connecting electrode 321 into contact with the contact electrode 110.
[0079] like Figure 8 As shown in the illustration, in one embodiment, the first connecting part is specifically a first magnetic element 210, and the second connecting part is specifically a second magnetic element 322. When the connecting component 320 comes into contact with the beauty device 200, the first magnetic element 210 and the second magnetic element 322 are magnetically attracted, thereby causing the connecting component 320 and the beauty device 200 to attract each other, and causing the connecting electrode 321 to contact the contact electrode 110. When the host computer 310 outputs an electrical signal to the connecting component 320, the connecting component 320 can transmit the electrical signal to the contact electrode 110 through the connecting electrode 321, thereby realizing the operation of firmware configuration or firmware upgrade of the beauty device 200.
[0080] The above solution, by configuring a first connecting part in the beauty device 200 and a connecting electrode 321 and a second connecting part in the connecting assembly 320, allows the beauty device 200 to contact the connecting assembly 320. The second connecting part cooperates with the first connecting part, ensuring full contact between the connecting electrode 321 and the contact electrode 110. Furthermore, the host computer 310 can output electrical signals to the connecting assembly 320 to perform firmware configuration or upgrades on the beauty device 200. This improves the connection stability between the beauty device 200 and the connecting assembly 320, and also enhances the stability of the beauty device's configuration system 400.
