[0002] Currently, wearable heating products on the market, such as heated clothing and heated boots, generally use metal fiber heating elements or constantan wire heating elements for their heating components. These materials have slow heating and low heat conversion efficiency. At the same time, the heating components are thick and take up a lot of space.

[0003] Secondly, the temperature control methods for existing heated clothing generally use manual temperature adjustment or Bluetooth control. When manually adjusting the temperature, it is very inconvenient to adjust the temperature when wearing an outer garment after putting on the heated clothing; Bluetooth temperature adjustment requires taking out a mobile phone and opening an app, which is also inconvenient.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "electrical connection," "fixed," etc., should be interpreted broadly. For example, "electrical connection" can be a fixed electrical connection, a detachable electrical connection, or an integral connection; it can be a mechanical electrical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0042] The specific implementation method is as follows, please refer to it. Figures 1 to 4This embodiment proposes a heating device 100 for wearable heating products, including a graphene heating element 1 and a voice control unit 2, as well as a power supply unit 3. The power supply unit 3 is connected to the voice control unit 2, and the voice control unit 2 is connected to the graphene heating element 1. The power supply unit 3 supplies power to the voice control unit 2 and the graphene heating element 1, while the voice control unit 2 controls the working state of the graphene heating element 1. The power supply unit 3 can be an external power source or a battery, and the external power input can be a DC 5V power input. The voice control unit 2 is equipped with a control circuit, and the graphene heating element 1 contains a graphene heating element that converts electrical energy into heat energy. The graphene heating element can radiate infrared rays similar to the wavelength of the human body, which are easily absorbed by the human body, heat up quickly, and have a high conversion efficiency, approaching 99%. At the same time, the graphene heating element can be designed as a thin sheet, reducing its volume and facilitating installation within the wearable heating product 100.

[0043] The graphene heating element 1 of this invention can be multiple, such as... Figure 3 and Figure 4 As shown in the figure, in one embodiment, the wearable heating product 200 of this utility model is a heated garment. This heated garment is divided into two different heating areas: the front and the back. As shown in the figure, two graphene heating elements 1 are provided on the front of the garment, and one graphene heating element 1 is provided on the back. Thus, both the front and back areas of the heated garment can emit heat through their respective graphene heating elements 1 to keep the body warm. It can be understood that in other embodiments, the heated garment can be divided into more heating areas, each of which can be equipped with a graphene heating element 1, and each heating area can also have a different number of graphene heating elements 1, such as 2, 3, 4, etc. In this embodiment, the graphene heating element 1 can be directly sewn and fixed to the wearable heating product 200, or it can be connected and fixed to the wearable heating product 200 by a detachable method such as Velcro.

[0044] like Figure 2 As shown, the voice control unit 2 of the heating device 100 of this utility model includes a control circuit module 21 and a voice acquisition device 22 connected to the control circuit module 21. The control circuit module 21 is connected to the graphene heating element 1. The voice acquisition device 22 is configured to acquire voice commands and transmit them to the control circuit module 21. The control circuit module 21 is configured to control the switching of the graphene heating element 1 and adjust the temperature of the graphene heating element 1 at different levels according to the voice commands.

[0045] The control circuit module 21 contains a control chip, and the voice acquisition device 22 is a microphone or other device. The voice acquisition device 22 can be fixed near the collar of the heated clothing, or the voice acquisition device 22 can be movable and placed in a fixed position on the wearable heated product 200 when not in use. When voice control is required, the user can simply bring the voice acquisition device 22 to the vicinity of the user's mouth.

[0046] The voice acquisition device 22 collects voice commands, such as "on," "off," "lowest setting," and "second lowest setting." After collecting the voice commands, the voice acquisition device 22 transmits them to the control circuit module 21. The control circuit module 21 stores preset control commands. When the voice command collected by the voice acquisition device 22 corresponds to a preset control command, the control circuit module 21 controls the graphene heating element 1 to perform the corresponding function, such as turning the graphene heating element 1 on, turning it off, adjusting the temperature to the lowest setting, or adjusting the temperature to the second lowest setting. The graphene heating element 1 can have multiple temperature settings, such as four or five, to meet different temperature requirements. In this embodiment, the control circuit module 21 is also equipped with a wake-up word. When in use, the user needs to first say the wake-up word, such as "Hey Siri," to wake up the control circuit module, and then say a temperature setting command, such as "Level 1," to easily adjust the temperature. This allows users to independently adjust the temperature according to their different needs, and different temperature settings can be freely adjusted. Since human body temperature needs and sensitivities vary, this temperature adjustment better meets the actual usage requirements of people with different temperature preferences.

[0047] Because the heating device 100 of this invention uses a voice control unit 2 to adjust the working temperature of the graphene heating element 1 by voice, no Bluetooth connection to a mobile phone is required for adjustment. Furthermore, even if a jacket is worn over the heating garment, the voice can penetrate the jacket and be collected by the voice collector 22, or the voice collector 22 can be placed on the jacket. Therefore, the temperature adjustment of the heating device 100 of this invention is much more convenient than that of the heating device 100 in existing wearable heating products 200.

[0048] Preferably, such as Figure 2 and Figure 3 As shown, the power supply unit 3 of the heating device 100 of this utility model includes a battery 31, a protection circuit 32, and a charging interface 33. The protection circuit 32 is connected between the battery 31 and the charging interface 33. The battery 31 is connected to the voice control unit 2. The charging interface 33 is connected to an external power source to charge the battery 31. Figure 3 As shown, the battery 31 can be charged by connecting to an external power source via a USB charging cable 5. The battery 31 is preferably a lithium battery.

[0049] The protection circuit 32 provides multi-functional protection for the battery 31 during charging and discharging, overheating, and overload. Preferably, in this embodiment, the heating device 100 has a power supply plug 4 connected to the voice control unit 2, and the battery 31 has a socket. The power supply plug 4 is detachably connected to the battery 31 through the socket on the battery 31. In this way, the battery 31 of the heating device 100 of this utility model is detachable, which is convenient for use and maintenance.

[0050] Preferably, such as Figure 2 As shown, the control circuit module 21 in this embodiment includes a main control chip 211 and a voice recognition chip 212 connected to the main control chip 211. The voice acquisition device 22 is connected to the voice recognition chip 212. That is, this embodiment uses a separate voice recognition chip 212 to recognize and process the voice signal, thereby improving the accuracy and speed of voice signal processing. This makes the voice control of the heating device 100 of this invention more accurate and stable, improving the user experience. The main control chip 211 controls the entire circuit, outputting a PWM signal to adjust the temperature level of the graphene heating element 1.

[0051] Preferably, in this embodiment, the main control chip 211 is model BK3432 and the voice recognition chip 212 is model WTK6900F-B03.

[0052] like Figure 2 As shown, in this embodiment, the voice control unit 2 further includes a temperature sensor 27, which is in close contact with the graphene heating element 1. The temperature sensor 27 collects the temperature information of the graphene heating element 1 and sends it to the control circuit module 21. The voice control unit 2 also includes a drive circuit 28 connected to the control circuit module 21 and a temperature signal processing circuit 29 connected to the control circuit module 21. In this embodiment, both the drive circuit 28 and the temperature signal processing circuit 29 are connected to the main control chip 211 of the control circuit module 21. The drive circuit 28 is connected to the graphene heating element 1, and the temperature signal processing circuit 29 is connected to the temperature sensor 27.

[0053] The temperature sensor 27 of the heating device 100 of this invention is in close contact with the graphene heating element 1. The temperature sensor 27 collects the temperature information of the graphene heating element 1 and sends it to the temperature signal processing circuit 29. The drive circuit 28 amplifies the PWM signal output by the main control chip 211 to drive the graphene heating element 1. The temperature signal processing circuit 29 converts the analog signal input from the temperature sensor 27 and calculates and identifies the temperature. The identified temperature signal is sent to the main control chip 211. The main control unit 211 adjusts the heating power of the graphene heating element 1 in a timely manner according to the temperature feedback from the temperature signal processing circuit 29, so that the temperature of the graphene heating element 1 reaches the preset temperature level.

[0054] Temperature sensor 27 is also used for over-temperature protection. When the heating temperature of graphene heating element 1 reaches the set temperature, temperature signal processing circuit 29 outputs a signal to main control chip 211. Main control chip 211 then controls drive circuit 28 to stop outputting to graphene heating element 1 and stop heating, thereby providing safety protection for the human body and preventing burns.

[0055] Preferably, the temperature corresponding to each of the settings of the graphene heating element 1 in the heating device 100 of this invention is a range value. Specifically, in this embodiment, the graphene heating element 1 has four temperature settings with four different temperature ranges when it is working, namely 55-60, 49-53, 43-47, and 37-40 degrees Celsius.

[0056] In this embodiment, the temperature control of the heating device 100 maintains the temperature within a preset temperature range. Compared to the common temperature control methods on the market that keep the temperature constant at a certain point, the constant temperature range of this embodiment allows the temperature to remain within a comfortable range that most people can adapt to. This solves the problem of needing to make specific adjustments during use due to differences in temperature and individual perception. For example, when the constant temperature varies within the range of 49-53 degrees Celsius, the user does not need to specifically adjust the temperature to 53 degrees Celsius or 49 degrees Celsius; the temperature automatically varies within the range of 49-53 degrees Celsius to adapt to different body temperature needs.

[0057] Please refer to Figure 5 The graphene heating element 1 of this utility model includes a graphene heating layer 11, on which a plurality of heating elements 111 are arranged at intervals to form a multi-point heating structure. The plurality of heating elements 111 are electrically connected to the driving circuit 28 respectively, and the plurality of heating elements 111 are connected in parallel.

[0058] In existing heating elements, the heating element is typically a single piece, which may result in insufficient heat distribution and uneven heating at the edges or in areas without a heating element. In contrast, the graphene heating layer 11 in this embodiment employs a multi-point heating design, resulting in a larger heating area and more uniform heat distribution within the heating element 1, leading to a better user experience. In this embodiment, the graphene heating layer 11 contains 12 heating elements 111, forming 12 heating points. It is understood that in other embodiments, the graphene heating layer 11 may also contain 16, 18, or 20 heating points, etc.

[0059] Specifically, such as Figure 6 As shown, the graphene heating element 1 of this invention also includes a protective layer 12 and a heat-retaining substrate layer 13 respectively disposed on two opposite sides of the graphene heating layer 11. The graphene heating layer 11 is connected to the drive circuit 28 of the voice control unit 2 via wires.

[0060] In this embodiment, the protective layer 12, the graphene heating layer 11, and the heat-retaining substrate layer 13 are integrated using carbon film technology. The protective layer 12 is made of a heat-resistant material to protect the graphene heating layer 11, while the heat-retaining substrate layer 13 is made of a tensile-resistant and heat-retaining material to prevent heat loss and provide insulation.

[0061] Furthermore, such as Figure 2 As shown, the voice control unit 2 in this embodiment also includes a voice command recording button 23 connected to the control circuit module 21. The voice command recording button 23 allows users to record control commands according to their own vocabulary habits and accents, thus avoiding the problem of being unable to wake up and control the device due to deviations in the user's pronunciation from the standard commands.

[0062] Better, such as Figure 2 As shown, the voice control unit 2 in this embodiment also includes a manual temperature adjustment button 24 and a temperature level status LED light 25 connected to the control circuit module 21. The manual temperature adjustment button 24 adjusts the temperature of the graphene heating element 1 at different levels, and the temperature level status LED light 25 can display different colors to correspond to the different temperature levels.

[0063] In other words, in addition to voice control, the heating device 100 of this embodiment can also adjust the heating temperature through the manual temperature adjustment button 24, which increases the temperature adjustment methods of the heating device 100.

[0064] Meanwhile, since this embodiment has four temperature settings, the corresponding LED indicator 25 also has four different colors: red, yellow, green, and blue, corresponding to the four temperature settings of 55-60, 49-53, 43-47, and 37-40, respectively. The LED indicator 25 allows users to intuitively understand which temperature setting is currently in use, facilitating subsequent temperature control adjustments.

[0065] Furthermore, the voice control unit 2 of this utility model also includes a control box 26, which houses the control circuit module 21. The drive circuit 28 and temperature signal processing circuit 29 of this embodiment are also housed within the control box 26. The control box 26 is equipped with a manual temperature adjustment button 24, a temperature level status LED light 25, and a voice command recording button 23. The voice acquisition device 22 can also be directly mounted on the control box 26. In this embodiment, all components of the heating device 100 except for the graphene heating element 1 and the power supply 3 can be integrated into a single control box 23. During installation, it is only necessary to connect the heating elements 1 in different areas of the wearable heating product 200 via wires and connect the power supply. This facilitates installation and also allows for mass production of the control box 26, reducing costs.

[0066] As one implementation method, such as Figure 7 As shown, the control box 26 in this embodiment is a single-control control box 26, that is... Figure 7 The control box 26 contains only one manual temperature adjustment button 24, which controls the temperature of one or more graphene heating elements 1. Figure 7 In the control box 26, a manual temperature adjustment button 24 is located in the middle of the upper surface. Two temperature setting LEDs 25 are symmetrically arranged on the upper and lower sides of the manual temperature adjustment button 24, with the LEDs forming an arc around the edge of the button. For example... Figure 8 As shown, a sewing ring 261 is provided on the control box 26 at a height of about 1 / 3 from the upper end face. The sewing ring 261 is provided to facilitate sewing the control box 26 onto the wearable heating product 200. At the same time, after sewing, the upper end face of the control box 26 is flush with the surface of the wearable heating product 200 without affecting the appearance.

[0067] Specifically, in this embodiment, the manual temperature adjustment button 24 of the single-control control box 26 can be used to turn the control box 26 on / off or to control it sequentially within a unit of time when adjusting the temperature level. For example, when the battery 31 is turned on and connected to the wearable heating product 200 via the power supply plug 4, the control box 26 automatically turns on, corresponding to a temperature of 55-60 degrees Celsius. At this time, the voice acquisition device 22 is also in working condition. If there is no voice input, the control circuit module detects the input of the manual temperature adjustment button 24. If the manual temperature adjustment button 24 is pressed for 0.1 seconds, the temperature is adjusted to 49-53 degrees Celsius; if it is pressed again for 0.1 seconds, the temperature is adjusted to 43-47 degrees Celsius; if it is pressed again for 0.1 seconds, the temperature is adjusted to 37-40 degrees Celsius; if it is pressed again for 0.1 seconds, the temperature is adjusted to 55-60 degrees Celsius, and so on. Pressing and holding the manual temperature adjustment button 24 for about 2 seconds turns off the control box 26.

[0068] As another implementation method, such as Figure 9 As shown, the control box 26 in this embodiment and Figure 7 The difference between the control box 26 and the control box 26 is that... Figure 9 The control box 26 in the middle is a dual-control control box 26, that is Figure 9 The control box 26 has two manual temperature adjustment buttons 24, which control the temperature of two or more graphene heating elements 1. Figure 9 In the control box 26, two spaced-apart manual temperature adjustment buttons 24 are positioned vertically at the center of the upper surface. Two temperature level status LEDs 25 are symmetrically arranged on the upper and lower sides of the outer edges of the two manual temperature adjustment buttons 24. In this embodiment, the two manual temperature adjustment buttons 24 respectively control the temperature of the graphene heating elements 1 in the front and back heating areas of the heated garment. Compared to a single-control box 26, the dual-control box 26 allows for more flexible individual control of a specific heating area to meet different needs.

[0069] In this embodiment, after the heating device 100 is powered on, if no voice or manual temperature adjustment is performed, the graphene heating element 1 enters a constant temperature control mode, such as the 55-60 degree temperature range. The temperature sensor 27 is placed on the graphene heating element 1 and feeds back the acquired temperature parameters to the temperature signal processing circuit 29. When the temperature reaches the set temperature range, the temperature signal processing circuit 29 outputs a control signal to the main control chip 211. The main control chip 211 controls the graphene heating element 1 to heat up slowly or stop heating to cool down slowly. When the temperature is lower than the set temperature range, the temperature signal processing circuit 29 outputs a control signal to the main control chip 211, and the main control chip 211 starts heating the graphene heating element 1 to maintain a comfortable temperature for the human body.

[0070] This utility model also proposes a wearable heating product 200, which is equipped with the aforementioned heating device 100 for wearable heating products. The wearable heating product 200 of this utility model includes clothing, trousers, hats, belts, scarves, and may also include other products such as heating pads.

[0071] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
