Description

Technical Field

[0001] The utility model relates to the technical field of heating and warming clothing, in particular to a multi-channel temperature control heating device for wearing heating products and a wearing heating product. Background Art

[0002] In cold winters, keeping warm in scenarios such as outdoor work, leisure, fishing, watching ball games, etc. is very important for people's physical health. However, wearing thick clothes brings inconvenience to people. Therefore, lightweight and heat-generating wearable heating products such as clothes and trousers are gradually popular in the market. Generally, multiple heating sheets are provided in wearable heating products such as thermal clothing corresponding to different regions of the human body such as the chest and abdomen, back, etc., so as to increase the heating area and improve the warming effect.

[0003] Since everyone has different feelings about temperature, for example, at the same temperature, some people feel hot while some people feel just right; or different parts of the same person's body have different sensitivities to temperature. For example, at the same temperature, the chest and abdomen may feel just right, but the back may feel a bit hot. Therefore, the temperature of the heating sheets on the wearable heating products needs to be adjustable to meet different human needs.

[0004] However, there are generally two ways to control the temperature of the heating sheets of existing wearable heating products. One is the constant temperature method. The temperature of the heating sheets in the constant temperature method is not adjustable, and the temperatures of all the heating sheets are the same, which cannot meet the different sensing requirements of different people for temperature. The other is the manual adjustment method. The manual adjustment method can adjust the temperature of the heating sheets. However, in the prior art, the manual adjustment method uniformly adjusts all the heating sheets in the wearable heating products. That is, if the user manually adjusts to 50 degrees, the temperatures of all the heating sheets in the wearable heating product are 50 degrees; if the user manually adjusts to 40 degrees, the temperatures of all the heating sheets in the wearable heating product are 40 degrees. In this way, it cannot meet the different temperature requirements of different parts of the same human body.

[0005] Therefore, the prior art needs to be improved. Summary of the Utility Model

[0043] The specific embodiments are as follows. Embodiment 1:

[0044] Please refer to Figures 1 to 7 , this embodiment provides a multi-channel temperature control heating device 100 for wearable heating products, which includes a heating part 10 and a control part 20, and also includes a power supply part 30. The power supply part 30 is connected to the control part 20, the control part 20 is connected to the heating part 10, the power supply part 30 supplies power to the control part 20 and the heating part 10, and the control part 20 is used to control the on and off of the heating part 10 and the temperature of the heating part 10. The power supply part 30 can be an external power supply or a battery, and the external power supply input can adopt a DC5V power supply input. The control part 20 is provided with a control chip and a control circuit, and the heating part 10 uses components such as heating wires and heating sheets to convert electrical energy into heat energy.

[0045] Specifically, the heating part 10 of the present utility model includes a plurality of heating sheets 11, and the plurality of heating sheets 11 can be respectively arranged in different areas of the wearable heating product 200. As Figure 3 and Figure 4As shown, as an implementation manner, the wearable heating product 200 involved in the present utility model is a heating clothing, which is divided into three different heating areas: the chest, the abdomen, and the back. A heating sheet 11 is separately provided in each heating area. As shown in the figure, two first heating sheets 111 (i.e., K1 in the figure) are provided on the chest of the heating clothing, two second heating sheets 112 (i.e., K2 in the figure) are provided on the abdomen of the heating clothing, and two third heating sheets 113 (i.e., K3 in the figure) are provided on the back of the heating clothing. In this way, heat can be emitted by the respective heating sheets 11 at the chest, abdomen, and back of the heating clothing to keep the human body warm. It can be understood that in other embodiments, the heating clothing can be divided into more heating areas, a heating sheet 11 is provided in each area, and different numbers of heating sheets 11, such as 1, 2, 3,... etc., can also be provided in each heating area of the heating clothing.

[0046] As Figure 2 shown, the control unit 20 of the present utility model includes a main control unit 21 and a plurality of temperature control switches 22 connected to the main control unit 21. The main control unit 21 is respectively connected to the plurality of heating sheets 11, and each temperature control switch 22 independently controls one heating sheet 11. That is, each temperature control switch 22 corresponds to control one heating sheet 11. The temperature control switch 22 issues a temperature control instruction to the main control unit 21, and then the main control unit 21 identifies which temperature control switch 22 issues the instruction according to the input interface, and then adjusts the temperature of the corresponding heating sheet 11.

[0047] As Figure 2 shown in the figure, in this embodiment, heating sheets K1, K2, and K3 are provided, and three temperature control switches are provided: temperature control switch 1, temperature control switch 2, and temperature control switch 3. Among them, temperature control switch 1 corresponds to controlling the on and off of heating sheet K1 and controlling the temperature of heating sheet K1; temperature control switch 2 corresponds to controlling the on and off of heating sheet K2 and controlling the temperature of heating sheet K2; temperature control switch 3 corresponds to controlling the on and off of heating sheet K3 and controlling the temperature of heating sheet K3. The main control unit 21 scans the input interface of the temperature control switch instruction. If it scans that temperature control switch 2 inputs a control instruction, then the main control unit 21 adjusts heating sheet K2 according to this instruction. In this way, the multiple heating sheets K1, K2, and K3 of the present utility model can all be independently controlled through their respective corresponding temperature control switches 22. As corresponding Figure 3 and Figure 4, if the user feels that the temperature of the heating element K3 on the back is high, the user can independently adjust the temperature of the heating element K3 by means of the temperature control switch 3, while the temperatures of the other heating elements K1 and K2 remain unchanged; if the user feels that the temperature of the heating element K2 on the abdomen is low, the user can independently adjust the temperature of the heating element K2 by means of the temperature control switch 2, while the temperatures of the other heating elements K1 and K3 remain unchanged. In this way, the user can make independent adjustments according to the temperature requirements of different body areas. Each output can be set to a different temperature and the gear can be freely adjusted. Different parts of the human body have different temperature requirements and sensitivities. The product of the present utility model better meets the actual use and meets the needs of different temperature groups.

[0048] Preferably, as Figure 2 shown, the power supply unit 30 of the multi-way temperature control heating device 100 includes a battery 31, and a charge and discharge interface 32 is provided on the battery 31. The charge and discharge interface 32 can be an interface with separate charge and discharge or an integrated charge and discharge interface. The control unit 20 further includes a power supply plug 26 and a power detection circuit 27; the power supply plug 26 is connected to the main control unit 21, the power supply plug 26 is detachably connected to the charge and discharge interface 32 in a pluggable manner, and the power detection circuit 27 is connected to the power supply plug 26 and the main control unit 21. The battery 31 receives external power input through the charge and discharge interface 32. In this embodiment, the external power input uses a 5V DC power input. At the same time, after being connected to the power supply plug 26 through the charge and discharge interface 32, it supplies power to the main control unit 21. As Figure 3 shown, the battery 31 can be charged by connecting to an external power supply through a USB charging cable 40. The battery 31 is preferably a lithium battery. When the multi-way temperature control heating device 100 is in use, the power supply plug 26 is plugged into the charge and discharge interface 32 of the battery 31. When the power supply plug 26 is connected to the charge and discharge interface 32 of the battery 31, the power detection circuit 27 is also connected to the battery 31, and the power of the battery 31 is detected. At the same time, the power detection circuit 27 sends the power signal of the battery 31 to the main control unit 21, and the main control unit 21 selectively issues an alarm signal according to the amount of the power signal. For example, when the battery power is lower than 20%, the user is reminded of insufficient power by means of a flashing light or voice, and please charge in time. In this way, in the wild, the power alarm information can enable the user to return indoors in time for charging to avoid frostbite due to the loss of the warming effect of wearing the heating product after running out of power.

[0049] As Figure 5 shown, the control unit 20 of the multi-way temperature control heating device 100 of the present utility model includes a controller 23, and the controller 23 can be arranged on the wearable heating product 200, as Figure 3As shown in the figure, the controller 23 is installed at the lower right front side of the clothes, and the controller 23 is exposed on the surface of the clothes. The controller 23 can be stitched and fixed on the wearable heating product 200, or detachably installed on the wearable heating product 200 through a buckle or the like. The controller 23 includes a housing 231, the main control unit 21 housed in the housing 231, and the plurality of temperature control switches 22 provided on the housing 231.

[0050] As Figure 5 shown in the figure, in this embodiment, the controller 23 has a polygonal housing 231. The main control unit 21 is disposed in the housing 231, and three temperature control switches 22 are provided on the upper surface of the housing 231. The housing 231, the main control unit 21, and the three temperature control switches 22 are integrated together to form the controller 23.

[0051] Each temperature control switch 22 is provided with identification marks of the human body and heating sheets at different distribution positions, so as to facilitate distinguishing which area of the heating sheet 11 is controlled by each temperature control switch 22. For example, a temperature control switch 22 reflects through the identification marks thereon that it controls the heating sheet 11 on the chest, abdomen, or back.

[0052] The plurality of temperature control switches 22 of this embodiment are integrated on one controller 23, which is convenient for centralized control of the plurality of heating sheets 11 and convenient for adjustment. At the same time, the main control unit 21 is also integrated in the controller 23. During installation, only the heating sheets 11 in different areas of the clothes need to be connected by wires and the power supply is already connected. The installation is convenient, and at the same time, it is convenient for batch production of the controller 23 and reduces costs.

[0053] Further, as Figure 2 and Figure 5 shown, the controller 23 further includes a plurality of gear state LED lights 24 provided on the housing 231. The plurality of gear state LED lights 24 are connected to the main control unit 21. Each temperature control switch 22 has different temperature gears to adjust a heating sheet 11 to have different temperatures. Each gear state LED light 24 is respectively associated with a temperature control switch 22, and each gear state LED light 24 can display different colors to correspond to different temperature gears of a temperature control switch 22. The temperature gear can be a certain temperature value or a certain temperature range value.

[0054] As Figure 5As shown in [figure reference], on the controller 23, a gear status LED light 24 is set near each temperature control switch 22. If each temperature control switch 22 and a gear status LED light 24 near it are combined into a set of light and switch combinations, then there are a total of three sets of light and switch combinations on the controller 23 in this embodiment. Each set of light and switch combinations is interrelated. That is, when the user adjusts the gear of the temperature control switch 22 in this set to make the heating element 11 it controls have different set temperatures, the gear status LED light 24 in this set shows different colors. In this embodiment, in each set of light and switch combinations, the lights are in a bent line shape surrounding the edge of the switch.

[0055] Specifically, in this embodiment, each temperature control switch 22 has 4 temperature gears to control its corresponding heating element 11 to have 4 different temperature ranges, which are four temperature gears of 55 - 60, 49 - 53, 43 - 47, and 37 - 40 degrees respectively, so that the heating elements it controls reach four temperature range values of 55 - 60, 49 - 53, 43 - 47, and 37 - 40 respectively. At the same time, in this embodiment, each gear status LED light 24 also has four different colors, such as red, yellow, green, and blue, to respectively correspond to the four temperature gears of 55 - 60, 49 - 53, 43 - 47, and 37 - 40. When each temperature control switch 22 adjusts the temperature gear, it can be controlled by the duration of pressing the button to turn on / off the controller 23 or the sequential button - pressing order within a unit time. For example, when the battery 31 is turned on and the wearable heating product 200 is connected through the power supply plug 26, the controller 23 automatically turns on, corresponding to the temperature of 55 - 60 degrees. Then press the temperature control switch 22 for a duration of 0.1S, then it is adjusted to the 49 - 53 - degree gear; press the temperature control switch 22 again for a duration of 0.1S, then it is adjusted to the 43 - 47 - degree gear; press the temperature control switch 22 again for a duration of 0.1S, then it is adjusted to the 37 - 40 - degree gear; press the temperature control switch 22 again for a duration of 0.1S, then it is adjusted back to the 55 - 60 - degree gear, and so on; long - press the temperature control switch 22 for about 2S, then the controller 23 is turned off.

[0056] As an embodiment, as Figure 5 shown in Figure 5 the upper temperature control switch 22 in [figure reference] corresponds to the chest heating element 11, the lower temperature control switch 22 corresponds to the back heating element 11, and the left - hand temperature control switch 22 corresponds to the abdominal heating element 11. When the user presses Figure 5 the upper temperature control switch 22 in [figure reference], then the temperature of the heating element 11 corresponding to the chest position of the wearable heating product 200 is correspondingly adjusted, and at the same time Figure 5 the upper - side gear status LED light 24 in [figure reference] shows the corresponding gear color. In this way, the controller 23 of the present utility model can very conveniently control the temperature of each heating element 11 and can visually display the temperature gear corresponding to the temperature of each heating element 11, improving the user experience.

[0057] The control unit 20 of the present utility model further includes a plurality of temperature sensors 25. Each of the temperature sensors 25 is respectively in close contact with one of the heating sheets 11. Each of the temperature sensors 25 collects the temperature information of the heating sheet 11 and sends it to the main control unit 21. As Figure 2 shown in the figure, three temperature sensors 25 are provided in this embodiment. Among them, temperature sensor 1 is in close contact with heating sheet K1 to collect the temperature of heating sheet K1; temperature sensor 2 is in close contact with heating sheet K2 to collect the temperature of heating sheet K2; temperature sensor 3 is in close contact with heating sheet K3 to collect the temperature of heating sheet K3. The main control unit 21 adjusts the heating power of the corresponding heating sheet 11 in a timely manner according to the temperature fed back by the temperature sensors 25, so that the temperature of the heating sheet 11 reaches the preset temperature.

[0058] Specifically, as Figure 2 shown in the figure, the main control unit 21 of this embodiment includes a main control chip 211, a driving circuit 212 connected to the main control chip 211, and a temperature signal processing circuit 213 connected to the main control chip 211; the driving circuit 212 is respectively connected to the plurality of heating sheets 11, and the temperature signal processing circuit 213 is respectively connected to the plurality of temperature sensors 25.

[0059] The main control chip 211 controls the entire circuit. The main control chip 211 outputs a PWM signal to control the heating temperature of each heating sheet 11, and the driving circuit 212 amplifies the PWM signal output by the main control chip 211 to drive the heating sheet 11. The temperature signal processing circuit 213 converts the analog signal input by the temperature sensor 25 and calculates to identify the temperature. Preferably, the model of the main control chip 211 in this embodiment is BK3432.

[0060] After the multi-channel temperature control heating device 100 of this embodiment is powered on, if no manual temperature adjustment is performed, each heating sheet enters the constant temperature control mode. For example, when entering the temperature range of 55 - 60 degrees, the temperature sensor 25 is placed on the heating sheet 11, and the obtained temperature parameter is fed back to the temperature signal processing circuit 213. When the temperature reaches the set temperature range, the temperature signal processing circuit 213 outputs a control signal to the main control chip 211, and the main control chip 211 controls the heating sheet 11 to heat slowly or stop heating to cool down slowly. When the temperature is lower than the set temperature range, the temperature signal processing circuit 213 outputs a control signal to the main control chip 211, and the main control chip 211 controls the heating sheet 11 to start heating to maintain a comfortable temperature for the human body.

[0061] The constant temperature control mode of the multi-channel temperature-controlled heating device 100 in this embodiment is to maintain the temperature within a preset temperature range. Compared with the constant temperature method that is generally constant at a certain temperature point in the market, the constant temperature control mode within a constant range in this embodiment can keep the temperature within a comfortable temperature range that most people can adapt to, solving the defect that different adjustments need to be made specifically during use due to the difference between temperature and individual feelings. For example, when the temperature varies within the range of 55-60 degrees, the user does not need to specifically adjust the temperature to 60 degrees or 55 degrees. The temperature automatically varies within the range of 55-60 degrees to adapt to the different body temperature perception needs of the human body.

[0062] Specifically, as Figure 6 and Figure 7 shown, the heating sheet 11 in this embodiment includes a heating body 101, a heat insulation cushion layer 102, a heat preservation cover layer 103, and a heat reflection layer 104 that are sequentially arranged in layers. The heating body 101 is connected to the main control unit 21. The heating body 101, the heat insulation cushion layer 102, the heat preservation cover layer 103, and the heat reflection layer 104 are sewn into one body. The heating body 101 is connected to the driving circuit 212 of the main control unit 21 through a wire 105. The heating body 101 is fixed on the side of the wearable heating product 200 facing the human body and fits with the human body, and the heat reflection layer 104 is fixed on the side of the wearable heating product 200 facing away from the human body to collect the dissipated heat.

[0063] In this embodiment, the heating body 101 is made of a heating wire or a flexible and bendable heating film. Preferably, when the heating body 101 is made of a flexible and bendable heating film, the heating film is a PI (polyimide film) heating film. The PI heating film has a good heating effect and is convenient for sewing and fixing on clothes at the same time.

[0064] In this embodiment, the heating body 101, the heat insulation cushion layer 102, the heat preservation cover layer 103, and the heat reflection layer 104 are generally sewn and fixed by fireproof wires. The heating sheet can use a heating wire as the heating body 6. The heat insulation cushion layer 102 is made of a heat insulation material, which can effectively prevent heat from being transferred outwards. At the same time, the heat insulation cushion layer 102 is used to fix the heating body 101; the heat preservation cover layer 103 can be made of materials such as heat preservation cotton, which can prevent heat from escaping and play a heat preservation role, and can also fix the heat insulation cushion layer 102; the heat reflection layer 104 can be made of an aluminum foil material, which reflects the heat back and further prevents heat from flowing out. Because the heating sheet 11 of this product is provided with a heat reflection layer 104, under the condition of the same heat generation, the temperature of the warming area can be increased by about 2 degrees Celsius, making full use of the heat generated by the heating sheet.

[0065] In this embodiment, the whole heating sheet 11 can be directly sewn and fixed on the wearable heating product 200, or can be connected and fixed to the wearable heating product 200 by a detachable method such as a magic tape.

[0066] Example 2, as Figure 8 shown, the difference between the multi-channel temperature-controlled heating device 100 for wearable heating products in this embodiment and that in Example 1 lies in the shape of the controller 23 and the setting of the lights. In Example 2, the housing 231 of the controller 23 is circular and can be connected. In other embodiments, the housing 231 of the controller 23 can also adopt other shapes. In Example 2, one gear state LED light 24 corresponding to each temperature control switch 22 is divided into two segments for setting.

[0067] Since other technical solutions in Example 2 are the same as those in Example 1, it has the functions and effects of the multi-channel temperature-controlled heating device 100 for wearable heating products in Example 1, and will not be elaborated here.

[0068] Example 3, as Figure 9 shown, the difference between the multi-channel temperature-controlled heating device 100 for wearable heating products in this embodiment and that in Example 1 is that the main control unit 21 in Example 3 further includes a Bluetooth module 214 connected to the main control chip 211, or a Bluetooth module 214 integrated on the main control chip 21.
