[0002] Heated clothing utilizes the latest heating technology, employing an external power source to heat and keep warm. It is currently used in many applications. In the cold autumn and winter seasons, heated clothing actively generates heat to keep the body warm. It is suitable for everyday casual wear and various outdoor activities, such as hunting, cycling, skiing, walking, jogging, yoga, and mountain climbing. Heated clothing is also suitable for outdoor work in various industries, including machining, construction, electrical engineering, logistics, shopping malls, real estate, security, and traffic police. In cold outdoor environments, it quickly heats up and keeps the wearer warm, conserving energy, providing comfort, and improving work efficiency.

[0003] However, wearable heated clothing currently suffers from the following drawbacks: most heated clothing on the market typically uses USB-5V voltage, resulting in low heating power, slow heating speed, and poor effectiveness. Some heated clothing uses customized power supplies, which improves heating speed, but suffers from poor product compatibility and high cost. Utility Model Content

[0006] In one implementation of the first aspect, the device further includes: a voltage matching circuit; the voltage matching circuit is connected to the power supply line of the power connector; the voltage matching circuit includes a device charging protocol identification chip, the device charging protocol identification chip being configured to match different voltages required by the device to meet different heating powers.

[0007] In one implementation of the first aspect, the voltage matching circuit is disposed at any position of the power supply connector, the switch module, and the splitter, and is connected to the power supply line of the power supply connector via a wiring at that position.

[0008] In one implementation of the first aspect, the power connector includes a USB plug; the device charging protocol identification chip is communicatively connected to an external power supply through the USB plug, so that the external power supply selects the voltage required by the wearable heating device from the fixed voltage levels in the USB programmable power protocol for power supply.

[0009] In one implementation of the first aspect, the heating module includes three heating units; the first heating unit is configured as a left chest X-ray, the second heating unit is configured as a right chest X-ray, and the third heating unit is configured as a back X-ray.

[0010] In one implementation of the first aspect, the first heating unit includes a first heating resistor, the second heating unit includes a second heating resistor, and the third heating unit includes a third heating resistor; one end of the first heating resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the second heating resistor, and the other end of the second heating resistor is connected to the positive terminal of the switch module; one end of the third heating resistor is connected to the negative terminal of the switch module, and the other end is connected to the positive terminal of the switch module.

[0011] In one implementation of the first aspect, the heating module includes five heating resistors: a left abdominal resistor, a right abdominal resistor, a back resistor, a left shoulder resistor, and a right shoulder resistor.

[0012] In one implementation of the first aspect, one end of the left belly plate resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the right belly plate resistor, the other end of the right belly plate resistor is connected to the first positive terminal of the switch module; one end of the back plate resistor is connected to the negative terminal of the switch module, and the other end is connected to the first positive terminal of the switch module; one end of the left shoulder plate resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the right shoulder plate resistor, the other end of the right shoulder plate resistor is connected to the second positive terminal of the switch module.

[0015] As described above, the wearable heating device and wearable heating clothing described in this application have the following beneficial effects:

[0016] This application innovatively designs a splitter structure in the heating device to distribute the electrical energy provided by the power supply to multiple heating units.

[0017] This application further adds a voltage matching circuit to the splitter structure. The device charging protocol identification chip in the voltage matching circuit communicates with an external power supply via a USB plug or socket, allowing the external power supply to select the voltage required by the wearable heating device from the fixed voltage levels in the USB programmable power protocol. These fixed voltage levels include 9V, 12V, 15V, and 20V. With the development of multi-voltage adjustable power banks, this application innovatively proposes a compromise between a fixed 5V power supply and a customized voltage power supply. By using the device charging protocol identification chip as a "decoy chip," a power bank with flexible voltage adjustment within a voltage range (e.g., 5V-20V or a voltage customized to actual needs above 20V) is used. Even with the current limited by the thickness of the power cord, increasing the supply voltage increases the heating power, thereby achieving a rapid heating effect in about 3 seconds.

[0053] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0054] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the illustrations only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0055] The following will combine Figures 1 to 15 This embodiment describes in detail the principle and implementation of a wearable heating device and wearable heating clothing, enabling those skilled in the art to understand the wearable heating device and wearable heating clothing of this embodiment without creative effort.

[0056] Please see Figure 1 The diagram shows the structural connection of the wearable heating device described in an embodiment of this application. Figure 1 As shown, this embodiment provides a wearable heating device 1, which specifically includes: a power connector 11, a switch module 12, a heating module 13, and a splitter 14.

[0057] The power connector 11 is connected to an external power supply.

[0058] The switch module 12 is connected to the power supply connector 11 and is configured to start and stop the heating operation of the device 1 and adjust the heating level of the device.

[0059] The heating module 13 is connected to the switch module 12 via a splitter 14. The heating module 13 includes a heating unit formed by connecting various heating elements in series and parallel.

[0060] In practical applications, the heating element can be a heating resistor, a carbon fiber heating wire, or a heating element.

[0061] The internal cavity of the splitter 14 is provided with different heating units and the pathways formed by the wiring of the power supply connector, the switch module and the temperature protection module.

[0062] In one embodiment, the device further includes a voltage matching circuit.

[0063] The voltage matching circuit is connected to the power supply line of the power connector 11; the voltage matching circuit includes a device charging protocol identification chip, which is configured to match different voltages required by the device 1 to meet different heating power requirements.

[0064] Furthermore, the voltage matching circuit is located at any position of the power supply connector, the switch module, and the splitter, and is connected to the power supply line of the power supply connector via a wiring at that position.

[0065] In one embodiment, the device further includes a temperature protection module.

[0066] The temperature protection module is embedded in the reserved space of the heating module; the temperature protection module is connected in series between the switch module and the power supply connector, and performs the on / off action of the heating circuit according to the temperature acquisition data.

[0067] Please see Figure 2 The diagram shows a schematic connection of the thermal insulation structure of the wearable heating device described in this embodiment. Figure 2 As shown, when the device includes a temperature protection module 8, i.e., a thermal protector 8, one end of the power connector is connected to an external power supply, and the other end is connected to one end of the thermal protector; the other end of the thermal protector is connected to one end of the switch module, and the other end of the switch module is connected to each heating unit. Thus, the thermal protector 8 is connected in series between the power connector and the switch module 12, and functions to detect temperature and perform the on / off action of the heating circuit according to the temperature detection result.

[0068] In practical applications, when the temperature of the heating element reaches a certain limit (such as a normally closed 50℃ thermal protector or a thermal protector corresponding to other temperature standards), the thermal protector (bimetallic strip) opens, thus shutting off the entire heating circuit. When the temperature drops, the thermal protector will close again, and the heating circuit will be ready to restart.

[0069] In practical applications, the temperature protection module can be a temperature protector, also known as a thermal protector. The thermal protector can be any of the following implementation methods: resettable bimetallic strip temperature sensing element, snap-action temperature controller, liquid expansion temperature controller, electronic temperature controller, and digital temperature controller.

[0070] Please see Figure 3 The diagram shows a schematic of the circuit structure of the wearable heating device described in an embodiment of this application. Figure 3 As shown, the voltage matching circuit is located at any position of the power supply connector 7, the switch module 5, and the splitter 4, and is connected to the power supply line of the power supply connector 7 through wiring at that position.

[0071] like Figure 3 As shown, the temperature protection module (thermal protector 8) is embedded in the reserved space of the heating module. In this embodiment, the wiring method of the temperature protection module in the splitter 4 is to connect it in series between the power supply connector 7 and the switch module 5, and then extend from the wiring outlet of the splitter 4 and be embedded in the reserved space of the third heating unit 3. The thermal protector 8 detects and senses the temperature around the heating unit and executes the on / off of the heating module (first heating unit 1, second heating unit 2 and third heating unit 3).

[0072] Furthermore, the power connector includes a USB plug. In practical applications, the USB plug can be USB-C.

[0073] The device charging protocol identification chip communicates with an external power supply via the USB connector, allowing the external power supply to select the voltage required by the wearable heating device from a fixed voltage level within the USB programmable power protocol. This fixed voltage level includes 9V, 12V, 15V, and 20V, or other voltage values ​​within the range of a power bank, or other voltage values ​​customized for the external power supply based on the specific application scenario. Therefore, compared to the existing fixed 5V power supply for heated clothing, this application can select the voltage required by the wearable heating device, such as 9V or 12V, which is higher than 5V. Thus, under the same current load on the same circuit, the higher voltage enables high-power heating.

[0074] In practical applications, if the USB plug does not find a voltage that matches the protocol in the connected power bank, the device will issue a light alarm and disconnect the device's circuit.

[0075] Please see Figure 4 The diagram shows the internal wiring of the splitter of the wearable heating device described in this embodiment. Figure 4 As shown, combined with Figure 3 The wiring harnesses shown (external power supply connection harness a, switch connection harness b, first heating unit harness c, second heating unit harness e, third heating unit harness d, and thermal protector harness f) Figure 4 A printed circuit board (PCB) corresponding to the internal pathways of a splitter is shown, with each wire harness soldered to its corresponding pad on the PCB. In practical applications, wire harness a can be a black 2-pin ribbon cable, wire harness b serves as the main switch line (input and output terminals can use black 4-pin ribbon cables), wire harness c can be a red silicone double parallel cable, wire harness d can be a blue silicone double parallel cable, wire harness e can be a yellow silicone double parallel cable, and wire harness f serves as a temperature detection protection line and can be a white silicone double parallel cable.

[0076] Please see Figure 5 The diagram shows the external structure of the splitter of the wearable heating device described in this embodiment. Figure 5 As shown, the left side is the wiring outlet for external power supply connection harness a, the upper left side is the wiring outlet for switch connection harness b, the upper right side is the wiring outlet for the first heating unit harness c, the lower center is the wiring outlet for the second heating unit harness e, the lower right side is the wiring outlet for the third heating unit harness d, and the lower left side is the wiring outlet for the thermal protector harness f. Each wiring outlet is equipped with a wire protection and reinforcement device to cover the wire diameter outlet.

[0077] Please see Figure 6 This is a schematic diagram of the first position of the voltage matching circuit of the wearable heating device described in an embodiment of this application. Figure 6 As shown, the voltage matching circuit 15 is located at the power supply connector 11 and is connected to the power supply line of the power supply connector 11. Please refer to... Figure 7 The diagram shows the voltage matching circuit schematic of the wearable heating device described in this application embodiment. Figure 7 The diagram shown illustrates the application principle of a voltage matching circuit. In this embodiment, the voltage matching circuit can be configured in... Figure 3 In the power supply connector, Figure 7 The long port on the left is a power connector 11, such as a USB-C socket (male or female), which can be connected to an external power supply. The Power System is where the decoy chip works, that is, the voltage output after voltage matching is available for the heating device.

[0078] In this embodiment, the voltage matching circuit is a decoy chip and its peripheral circuitry, also known as a decoy circuit. In practical applications, the decoy chip and its peripheral circuitry are connected to the power connector 11, and are custom-made by the factory to have voltage matching functionality, i.e., a USB-C socket (male or female) with voltage matching functionality.

[0079] like Figure 7 As shown, the device charging protocol identification chip in the voltage matching circuit refers to a chip that can send a request signal to the external power supply, causing the external power supply to select the voltage value corresponding to the request signal from multiple voltage levels, thus playing a "deception" function. Figure 7 The decoy chip can be set to a target requested voltage of 5V, 9V, 12V, 15V, 20V, or other practically required voltage values ​​via an external resistor R. The decoy chip sends a target voltage request signal to an external power supply via a power connector 11 to obtain a matching voltage value to power the wearable heating device. In practical applications, the target requested voltage and the values ​​of the external resistor are determined by the manufacturer based on the actual power requirements of the heating device during customization.

[0080] Please see Figure 8 This is a schematic diagram showing the second position of the voltage matching circuit of the wearable heating device described in this application embodiment. Figure 8 As shown, the voltage matching circuit 15 is located at the position of the splitter 14 and is connected to the line of the splitter 14.

[0081] Please see Figure 9 This is a schematic diagram of the third position of the voltage matching circuit of the wearable heating device described in this application embodiment. Figure 9 As shown, the voltage matching circuit 15 is located at the position of the switch module 12 and is connected to the circuit of the switch module 12.

[0082] It should be noted that when the voltage matching circuit 15, i.e., the decoy circuit, described in this application is located at the splitter and switch module positions, its circuit wiring principle is the same as... Figure 7 The wiring methods shown are the same, the only difference being the location of the decoy circuit. The length of each trace needs to be adjusted accordingly.

[0083] In one embodiment, the heating module includes three heating units; the first heating unit is configured as a left chest X-ray, the second heating unit is configured as a right chest X-ray, and the third heating unit is configured as a back X-ray.

[0084] Please see Figure 10 The diagram shows the three-zone heating principle of the wearable heating device described in this application embodiment. Figure 10As shown, the switch module 12 is a single-channel switch module. The first heating unit includes a first heating resistor R1, the second heating unit includes a second heating resistor R2, and the third heating unit includes a third heating resistor Rb.

[0085] One end of the first heating resistor R1 is connected to the negative terminal of the single-channel switch module 12, and the other end is connected to one end of the second heating resistor R2. The other end of the second heating resistor R2 is connected to the positive terminal of the single-channel switch module 12.

[0086] One end of the third heating resistor Rb is connected to the negative terminal of the single-channel switch module 12, and the other end is connected to the positive terminal of the single-channel switch module 12. Here, SW represents... Figure 3 The thermal insulator 8 is normally closed when the temperature inside the heated garment is less than or equal to 50°C, and open when the temperature is greater than 50°C.

[0087] Furthermore, if a heating element malfunctions, the heating operation status is determined based on the series and parallel connections of the circuit containing that heating element. For example... Figure 10 As shown, if the second heating resistor R2 experiences an open circuit fault, the first heating resistor R1, which is connected in series with it, will not work, while the third heating resistor Rb, which is connected in parallel with the first heating resistor R1 and the second heating resistor R2, can work normally.

[0088] Please see Figure 11 This is a schematic diagram of the three-zone heating of the wearable heating device described in this application embodiment. Figure 11 As shown, the first heating resistor R1 is configured as the left chest film, the second heating resistor R2 is configured as the right chest film, and the third heating resistor Rb is configured as the back film.

[0089] In another embodiment, the heating module includes five heating resistors: a left abdominal resistor, a right abdominal resistor, a back resistor, a left shoulder resistor, and a right shoulder resistor.

[0090] In practical applications, the heating element of the left abdominal panel can be placed in the left pocket of the jacket, and the heating element of the right abdominal panel can be placed in the right pocket of the jacket.

[0091] Please see Figure 12 The diagram shows the five-zone heating principle of the wearable heating device described in this application embodiment. Figure 12 As shown, the switch module 12 is a dual-channel switch module, and the heating module includes five heating resistors: left abdominal plate resistor R1, right abdominal plate resistor R2, back plate resistor Rb, left shoulder plate resistor R3, and right shoulder plate resistor R4.

[0092] like Figure 12As shown, one end of the left abdominal resistor R1 is connected to the negative terminal (second terminal) of the first heating path I of the dual-channel switch module 12 for starting and stopping, and the other end is connected to one end of the right abdominal resistor R2. The other end of the right abdominal resistor R2 is connected to the positive terminal (first positive terminal) of the first heating path I of the dual-channel switch module 12 for starting and stopping.

[0093] One end of the backplate resistor Rb is connected to the negative terminal (second terminal) of the first heating path I of the dual-channel switch module 12 for starting and stopping, and the other end is connected to the positive terminal (first positive terminal) of the first heating path I of the dual-channel switch module 12 for starting and stopping.

[0094] One end of the left shoulder plate resistor R3 is connected to the negative terminal (second terminal) of the second heating path II of the dual-channel switch module 12 for starting and stopping, and the other end is connected to one end of the right shoulder plate resistor R4. The other end of the right shoulder plate resistor R4 is connected to the positive terminal (second positive terminal) of the second heating path II of the dual-channel switch module 12 for starting and stopping; wherein, the negative terminal of the first heating path I is connected to the negative terminal of the second heating path II, that is, the second terminal of the dual-channel switch module 12. Here, SW represents... Figure 3 The thermal insulator 8 is normally closed when the temperature inside the heated garment is less than or equal to 50°C, and open when the temperature is greater than 50°C.

[0095] Please see Figure 13 This is a schematic diagram of the five heating zones of the wearable heating device described in this application embodiment. Figure 13 As shown, the heating module includes five heating resistors: left abdominal resistor R1, right abdominal resistor R2, back resistor Rb, left shoulder resistor R3, and right shoulder resistor R4. The left abdominal resistor R1 is located in the left pocket of the heating garment, the right abdominal resistor R2 is located in the right pocket of the heating garment, the back resistor Rb is located on the back of the heating garment, the left shoulder resistor R3 is located on the left shoulder of the heating garment, and the right shoulder resistor R4 is located on the right shoulder of the heating garment.

[0096] It should be noted that the left abdominal piece, right abdominal piece, back piece, left chest piece, and right chest piece mentioned in this application are only a few implementations of the heating location. In addition, various locations on clothing, such as the shoulder area, left back, right back, and lower back, are also within the scope of protection of this application. The above embodiments of this application use heated clothing as an example to illustrate the heating principle. Furthermore, vests, jumpsuits, trousers, hats, gloves, or shoes and socks are also within the scope of protection of this application, provided that the wearable heating device functions normally. The above embodiments of this application use three-zone heating and five-zone heating as examples to illustrate the heating principle. In addition, the number of individual heating zones and heating zones other than three or five zones are also within the scope of protection of this application, provided that they do not affect the implementation of the heating principle of this application.

[0097] Please see Figure 14 The diagram shows a schematic of the switching module circuit of the wearable heating device described in an embodiment of this application. Figure 14 The circuit diagram of the switch module 12 is shown. The circuit of the switch module 12 includes a main chip, which can be a chip with multiple input / output (I / O) ports capable of implementing the switch module function of this application. The main chip includes multiple I / O ports, combined with... Figure 3 The physical appearance of the switch module 5 includes a square LED light frame and switch S1. The main chip's IO2, IO3, and IO4 ports are used to control the first, second, and third indicator lights, respectively. In practical applications, the first indicator light is blue, the second is white, and the third is red. When the blue indicator light controlled by the main chip's IO2 illuminates, the LED light frame lights blue; when the white indicator light controlled by the main chip's IO3 illuminates, the LED light frame lights white; and when the red indicator light controlled by the main chip's IO4 illuminates, the LED light frame lights red. Specifically, the LED light frame can be a frosted material LED board, with one LED bead under each of the four sides of the square light frame.

[0098] like Figure 14 As shown, the circuit of the switch module 12 includes a pressable reset switch S1. When the switch is pressed, a low-level signal is transmitted to the IO5 port of the main chip. The IO5 port is used to detect different button actions of the switch S1, such as a single press, a fixed number of presses, and a long press, thereby realizing different heating operations, specifically including:

[0099] (1) In practical applications, after the switch S1 is pressed for the first time, the power supply voltage, power supply current or power supply time duty cycle is adjusted to start the heating path of the device 1 at the highest power level in the first gear. After the switch S1 is pressed for the second time, the power supply voltage, power supply current or power supply time duty cycle is reduced to maintain the heating path of the device 1 at the second gear. After the switch S1 is pressed for the third time, the power supply voltage, power supply current or power supply time duty cycle is further reduced to maintain the heating path of the device 1 at the third gear.

[0100] (2) In another practical application, after the switch S1 is pressed for the first time, the heating path of the device 1 is started at the lowest power level by adjusting the duty cycle of the power supply voltage, power supply current or power supply time. After the switch S1 is pressed for the second time, the heating path of the device 1 is maintained at the second power level by increasing the duty cycle of the power supply voltage, power supply current or power supply time. After the switch S1 is pressed for the third time, the heating path of the device 1 is maintained at the third power level by further increasing the duty cycle of the power supply voltage, power supply current or power supply time.

[0101] (3) In other applications, the heating levels can also be switched through different combinations of long presses, short presses, and continuous clicks on switch S1. In other applications, Figure 14 The switch S1 in this application is only a symbolic representation of a switch. Other switches, such as touch screen switches, various virtual electronic switches, or switch signals converted from voice and gestures in AI (Artificial Intelligence) applications, are input from the main chip's IO5 port and are all within the scope of protection of this application.

[0102] Combination Figure 14 and Figure 4 , Figure 5 In practical applications, wire harness b serves as the main switch wire. The input and output terminals can use a black 4-pin ribbon cable, which can include the power supply voltage VDD (e.g., 9V, 12V, 15V, and 20V), the negative power supply ground, the chip circuit voltage VCC converted from VDD, and the on-terminal P- of the switching MOSFET M1. Specifically, the on-terminal P- is the ground voltage connected after the source S1, S2 and drain D1, D2 of the chip M1 (e.g., a dual N-channel MOSFET AP8205) are turned on. This ground voltage is ultimately connected to the negative terminal of the switching module via P-. Figure 10 or Figure 12 The corresponding location of the heating unit in a specific example.

[0103] Please see Figure 15 The image shown is a structural schematic diagram of the wearable heated garment described in an embodiment of this application. Figure 15 As shown, this embodiment provides a wearable heated garment, which includes the above-mentioned device; the device is fixed in the inner layer of the wearable heated garment.

[0104] In one embodiment, the device includes: a power connector, a switch module, a heating module, and a splitter. The power connector is connected to an external power supply; the switch module is connected to the power connector and configured to start / stop the heating path of the device and adjust the heating level of the device; the heating module is connected to the switch module through the splitter, and the heating module includes a heating unit formed by connecting various heating elements in series and parallel; the internal cavity of the splitter is provided with different heating units and pathways formed by the wiring of the power connector, the switch module, and the temperature protection module.

[0106] In one embodiment, the voltage matching circuit is disposed at any location of the power supply connector, the switch module, and the splitter, and is connected to the power supply line of the power supply connector via a wiring at that location.

[0107] In one embodiment, the power connector includes a USB plug; the device charging protocol identification chip communicates with an external power supply through the USB plug, so that the external power supply selects the voltage required by the wearable heating device from the fixed voltage levels in the USB programmable power protocol.

[0108] In one embodiment, the heating module includes three heating units; the first heating unit is configured as a left chest X-ray, the second heating unit is configured as a right chest X-ray, and the third heating unit is configured as a back X-ray.

[0109] In one embodiment, the first heating unit includes a first heating resistor, the second heating unit includes a second heating resistor, and the third heating unit includes a third heating resistor; one end of the first heating resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the second heating resistor, and the other end of the second heating resistor is connected to the positive terminal of the switch module; one end of the third heating resistor is connected to the negative terminal of the switch module, and the other end is connected to the positive terminal of the switch module.

[0110] In one embodiment, the heating module includes five heating resistors: a left abdominal resistor, a right abdominal resistor, a back resistor, a left shoulder resistor, and a right shoulder resistor.

[0111] In one embodiment, one end of the left belly plate resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the right belly plate resistor, the other end of the right belly plate resistor is connected to the first positive terminal of the switch module; one end of the back plate resistor is connected to the negative terminal of the switch module, and the other end is connected to the first positive terminal of the switch module; one end of the left shoulder plate resistor is connected to the negative terminal of the switch module, and the other end is connected to one end of the right shoulder plate resistor, the other end of the right shoulder plate resistor is connected to the second positive terminal of the switch module.

[0113] In practical applications, combined with Figure 11 A diagram illustrating the three-zone heating pattern, as shown below. Figure 15As shown, the switch module 5 can be embedded in the inner layer of the garment and fixed at the chest position so that the user can locate the switch S1 in the switch module 5 by touch without affecting the appearance of the garment.

[0114] In practical applications, such as Figure 15 As shown, the USB-C cable can be embedded in the interlayer of the jacket pocket, with the USB-C plug protruding from the interlayer and placed in the jacket pocket. This allows the user to place the power bank in the pocket after connecting the USB-C plug to the power bank, thus not affecting the appearance of the garment.

[0115] In summary, the wearable heating device and garment described in this application innovatively incorporate a splitter structure within the heating device. This structure distributes the electrical energy supplied by the power supply to multiple heating units. Furthermore, each heating unit can be flexibly distributed across various parts of the garment, rather than just a single piece on the back. This significantly increases the effective heating area, achieving a better cold-proof and warm-keeping effect. Moreover, a voltage matching circuit is added to this splitter structure. The device charging protocol identification chip in the voltage matching circuit communicates with an external power supply via a USB plug or socket, allowing the external power supply to select the voltage required by the wearable heating device from the fixed voltage levels in the USB programmable power protocol. Therefore, compared to the fixed 5V of existing heating garments, this application utilizes the device charging protocol identification chip as a "decoy chip" to use 9V, 12V, or other set voltages. Even with current limitations imposed by wire thickness, increasing the supply voltage provides sufficient heating power, achieving a rapid heating effect in approximately 3 seconds.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
