Description

Technical Field

[0001] The present invention relates to the technical field of heating material processing and packaging technology, and more specifically, to a heating source and its production process for use in the fields of smart wearables and medical consumables. Background Art

[0002] Heat sources (or heating modules), as electric heating materials, generate heat energy by utilizing the thermal effect of current from a power source and the resistance of the heating material. They are widely used in both civilian and industrial applications. Currently, commercially available resistance wire, carbon fiber, carbon nanotube, and graphene technologies suffer from drawbacks such as slow heating, uneven and unstable heating temperatures, and imperfections in seam-forming processes. Furthermore, heat sources are produced using etching technology, which is associated with high production costs, low efficiency, an environmentally unfriendly production process, pollutant emissions, low waste recovery rates, and rigid, unseamable, and bendable PET or PI film packaging. Furthermore, the lack of heat storage, insulation, and temperature control technologies in current civilian heating products is precisely the research and development direction of our industry's background technology.

[0003] Therefore, how to ensure that the heat source heats up quickly and evenly and stably, and maintain good ductility, flexibility, corrosion resistance and good mechanical properties when encapsulating or sewing together, as well as how to reduce temperature dissipation and loss and other temperature control issues have become technical problems that technical personnel in this field urgently need to solve. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the above-mentioned defects of the prior art, such as high production cost, slow efficiency, environmentally unfriendly production process, emission of pollution sources, low recovery rate of residual materials and waste, and the relatively hard and unseamable PET or PI film packaging through etching, as well as temperature control problems such as how to reduce temperature dissipation and loss.

[0005] The present invention is implemented by the following technical solutions:

[0006] A heat source for use in the fields of smart wearables and medical consumables, comprising a heat source body made of pure nickel, a temperature control module, and a battery. The heat source body is encapsulated by a first composite material, wherein the first composite material is composed of a polyester or nylon composite TPU film. The heat source body is insulated by a second composite material, wherein the second composite material is composed of a polymer nano closed-cell structure material composited with thermal insulation cotton.

[0007] Furthermore, the thickness of the TPU film is 0.06 mm, the thickness of the polymer nano closed-cell structure material is 0.7 mm, and the weight per square meter is 48 grams.

[0008] Furthermore, the temperature control module includes: a temperature detector for detecting the temperature of the heat source body and generating a temperature signal; an MCU module, which is provided with a temperature threshold, wherein the temperature feedback end of the MCU module is connected to the output end of the temperature detector, and is used to receive the temperature signal, and the MCU module compares the input temperature signal with the temperature threshold, and outputs a control signal based on the comparison result; an electronic switch, whose signal input end is coupled to the output end of the MCU module, and is used to receive the control signal, and the output end of the electronic switch is connected to an input end of the heat source body, and the control signal is used to control the electronic switch to be turned on or off.

[0009] Furthermore, when the temperature signal fed back by the temperature detector is lower than the temperature threshold, the MCU module outputs the control signal to control the conduction of the electronic switch, and the turned-on electronic switch outputs working power to the heat source body; when the temperature signal fed back by the temperature detector reaches or exceeds the temperature threshold, the MCU module stops outputting the control signal, and the electronic switch is controlled to close, thereby cutting off the working power of the heat source body.

[0010] In a second aspect, the present invention further discloses a production process for producing and packaging a heat source, comprising the following steps:

[0013] Step 3: placing the heat source body on the first composite material, and pressing the first composite material and the heat source body together through a hot pressing high-frequency process to complete the packaging of the heat source body;

[0014] Step 4: Perform soldering on the two connection ports of the encapsulated heat source body using automated equipment;

[0015] Step 5: Install the connected heat source body into a wearable article or medical consumables, and cover the outer surface of the connected heat source body with the second composite material.

[0016] Furthermore, in step 1, the circuit wiring diagram calculates the width and line length of the heating material when using a specific product based on the resistivity of the pure nickel metal and draws a corresponding circuit wiring diagram.

[0017] Furthermore, in step 5, the heat source body is installed in the interlayer between the outer surface and the inner surface of the wearable article or medical consumables.

[0018] Furthermore, in step 5, the second composite material is placed between the outer surface and the inner surface of the wearable article or medical consumable, and the second composite material covers the upper surface of the heat source body.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The heat source of the present invention uses pure nickel (N6) as the electrothermal material. Compared to other electrothermal materials, it has high electrical and thermal conductivity, as well as excellent ductility and flexibility, making it suitable for manufacturing smart wearable or medical consumable products requiring flexibility. Furthermore, the present invention utilizes the electronic engraving process of a laser engraving machine to produce the heat source at a lower cost and time.

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1As shown, in the first embodiment of the heat source for the field of smart wearables and medical consumables of the present invention, the heat source 100 for the field of smart wearables and medical consumables includes a heat source body 104, a temperature control module 105 and a battery, and the battery is a rechargeable lithium battery. Specifically, the heat source body 104, as an electric heating material, generates heat energy by utilizing the thermal effect of the power supply current and the resistance of the heating material, and is widely used in civil and industrial applications. In the present invention, the heat source body 104 is encapsulated by a first composite material, and the first composite material is composed of a polyester or nylon composite TPU film. In addition, the heat source body 104 is insulated by a second composite material, and the second composite material is composed of c. The thickness of the TPU film is 0.06 mm, the thickness of the polymer nano closed-cell structure material is 0.7 mm, and the weight per square meter is 48 grams.

[0028] In the present invention, the melting point of the TPU film is 110 degrees, the hot pressing high-frequency single-mode temperature is 130-150 degrees, and the thickness is 0.06 mm.

[0029] In this technical solution, heat source body 104 utilizes pure nickel (N6) as an electric heating material, which possesses high electrical and thermal conductivity and is widely used in industrial products. Pure nickel (N6) exhibits excellent ductility, flexibility, corrosion resistance, and mechanical properties. Its melting point ranges from 1450°C to 1455°C, its boiling point ranges from 2730°C to 2738°C, and its density is 8.9 grams per cubic centimeter.

[0030] When the power of the heat source 100 is sufficient, the user can heat up through the clothing, hat, or boots they wear when working outdoors and suffer from hypothermia, thereby achieving a life-saving function. In addition, it can also be used for medical consumables that come into close contact with the patient to achieve a hot compress function. The heating performance of the present invention is as follows: in actual measurements with a voltage of 7.4V, a current of 1.4A, and a power of 10W, the temperature rises in 1s, and can be heated to 43°C within 60s and 60°C within 300s (measured in a 25°C temperature environment).

[0031] Among them, the secondary deep processing of pure nickel is highly efficient, and it only takes 160 seconds to process a heating circuit on a plane (10 meters long, 1.8 mm wide and 0.05 mm thick), with low energy loss and low processing costs.

[0032] In addition, the present invention utilizes the electronic engraving process of a laser engraving machine to produce a heat source at a lower cost and time, and uses a polyester or nylon composite TPU film, combined with a hot pressing and high-frequency packaging process, to achieve the properties of a heat source such as softness, insulation, waterproofness, and sewing. It uses new heat storage and insulation materials to reduce temperature loss, and uses a temperature control module for temperature control, thereby extending the use time of the power supply and the efficiency of electric heat energy conversion.

[0033] In a second aspect, in an embodiment of the present invention, the production process of a heat source for use in the field of smart wearables and medical consumables comprises the following steps:

[0034] Step 1: Calculate the width and line length of the heating material of the specific product and determine its circuit wiring diagram.

[0035] Specifically, the circuit wiring diagram is based on the knowledge points and formulas related to voltage, resistance, current, and power in logistics, combined with the resistivity of pure nickel metal properties, to preliminarily calculate the width and line length of the heating material when using a specific product and generate a circuit wiring diagram.

[0036] For example, the voltage of the heating product is set to 7.4V, the battery capacity is 3000mA, the total power is 22.2W, and the battery setting working time is 2 hours. The current is calculated to be 1.5A (I=Wtotal / V / T), the heating source power is 11.1W (Wsource=Wtotal / T), the resistance value is 4.93 ohms (R=V / I), and the resistivity of pure nickel N6 is 8.9µΏ.CM. The material thickness is set to 0.05mm and the line width is 1.8mm. The calculated plane line length in the heating source area is 4.99 meters (L=S*R / P). The line width or line spacing is adjusted according to actual needs. After the calculation is completed, the circuit wiring diagram (or heating layout) is designed.

[0037] Step 2: Place the circuit wiring diagram on a laser engraving machine to complete the engraving and then coat the packaging film.

[0038] Specifically, placing the circuit wiring diagram (or heating pattern) on a laser engraving machine to complete the engraving and then coating the packaging film, and then using the electronic laser engraving process, can significantly improve the efficiency of the machine equipment, with the efficiency increased by 3.75 times, from 600 seconds before to 160 seconds now. The use of electronic laser engraving technology has the following technical effects:

[0039] 1. The efficiency of machinery and equipment has been greatly improved;

[0040] 2. The remaining heat source materials after laser cutting can be recycled and processed again. The entire processing process is environmentally friendly and pollution-free, and ecologically sustainable.

[0041] 3. The maximum processing range of the laser cutting machine is 650*550 mm, which meets product requirements; the processing process does not produce any contact, will not generate any machine stress and deformation, the processing graphics can be changed at will, greatly saving the cost of molds; the processing line width accuracy can be ensured to 0.8mm and below, with high precision and density.

[0042] Step 3: placing the heat source body 104 on the first composite material, and pressing the first composite material and the heat source body together through a hot pressing high-frequency process to complete the packaging of the heat source body 104;

[0043] Due to the process used in the industry, PET or PI film is encapsulated, which becomes a hard body after encapsulation and cannot be sewn or bent. It can only be used for industrial products and cannot be used in smart wearable or medical consumable products that require flexibility.

[0044] In this solution, the electric heating high-frequency process in the shoe industry is adopted.

[0045] The laser-engraved circuit wiring diagram (or semi-finished circuit product) is pressed onto the first composite material to complete the insulation, sealing, bending, sewing, waterproofing and other treatments on the outside of the heating source material to form a composite film heating source.

[0046] The first composite material is formed by laminating polyester or nylon composite TPU film through a laminating machine.

[0047] More specifically, polyester or nylon and a TPU film that can withstand the melting point of the material at 110 degrees are compounded into a composite material, and are simultaneously hot-pressed at a high-frequency single-mode temperature of 130-150 degrees for compression packaging.

[0048] Step 4: perform soldering on the two connection ports of the packaged heat source body 104 using automated equipment;

[0049] Specifically, fully electric machinery and equipment are used to perform wiring and soldering processing on the two connection ports of the composite film heating source, and thus the packaging production of the composite film heating source is completed.

[0050] Step 5: Install the heat source body 104 after wiring into a wearable article or medical consumables, and cover the outer surface of the heat source body 104 after wiring with the second composite material.

[0051] Specifically, the encapsulated heating film is installed between the outer and inner surfaces of a wearable device or medical consumable, forming a sandwich. Furthermore, working from the outside in, the second composite material is placed on the second layer of the product fabric, the encapsulated heat source on the third layer, and the fourth layer on the inner lining of the product. This completes the assembly of the components.

[0052] For example, the heat source of the present invention is encapsulated in a shoe body. The order of placing the components is described one by one from the outside to the inside:

[0053] Layer 1: The inherent fabric of the shoe surface;

[0054] The second layer: The second composite material composed of polymer nano closed-cell structure material and thermal insulation cotton provides thermal insulation, significantly reducing the heat loss rate of the feet and reducing temperature loss;

[0055] Layer 3: The heat source body 104 encapsulated by the first composite material, the heat source body 104 provides heat energy temperature;

[0056] Layer 4: The inherent lining of the shoe.

[0057] In order to adapt to the heat source body 104 of pure nickel metal, the present invention improves the existing temperature control module, such as Figure 2-Figure 4 As shown, in the embodiment of the heat source for the field of smart wearable and medical consumables of the present invention, the control module 10 of the heat insulation heat source includes a power supply component 101, an MCU module 102, an electronic switch 103, a temperature detector 105 (corresponding to Figure 1 temperature sensor in the temperature range), temperature display component 106 and start switch 107.

[0058] The power supply component 101 is used to receive a power supply signal and perform voltage stabilization processing on the input power supply signal.

[0059] The MCU module 102 is provided with a temperature threshold, which has the functions of calculation, signal comparison and outputting a control signal.

[0060] The MCU module 102 is used to receive the temperature signal fed back by the temperature detector 105, then compare the fed back temperature signal with a temperature threshold, and then output a control signal or control instruction according to the comparison structure.

[0061] The electronic switch 103 is used to control the working state of the heat source body 104 .

[0062] The temperature detector 105 is used to obtain or detect an ambient temperature signal within the heat source body 104 .

[0063] The temperature display component 106 is used to display or represent the real-time temperature of the environment in each temperature zone detected by the temperature detector 105 inside the heat source body 104.

[0064] The start switch 107 is used to input a control start signal to the MCU module 102 .

[0065] Specifically, if Figure 2 As shown, the power input terminal of the power supply component 101 (corresponding to the INT terminal of U101) is connected to the output terminal (corresponding to the OUT+ terminal) of the external power supply (or mobile power supply), and the output terminal of the power supply component 101 is connected to the power input terminal of the MCU module 102 (corresponding to the VDD terminal of U102).

[0066] The power supply component 101 is used to receive the power signal input from the front-stage power supply circuit, stabilize the input power signal, and then output it to the power input terminal of the MCU module 102 (corresponding to the VDD terminal of U102).

[0067] The heat source 104 is an electric heating material that generates heat energy by utilizing the thermal effect of the power supply current and the resistance of the heating material. Pure nickel (N6) is currently used as the heating material. Pure nickel has excellent ductility, flexibility, corrosion resistance, and mechanical properties. It has a melting point of 1453 degrees Celsius, a boiling point of 2732 degrees Celsius, and a density of 8.9 grams per cubic centimeter.

[0068] Furthermore, the temperature detector 105 is in contact with the heat source body 104 or is directly set on the wearable article or medical consumable to be heated, and is used to detect the real-time temperature signal of the component to be heated and feed back the obtained temperature signal to the MCU module 102.

[0069] Specifically, the MCU module 102 is provided with a temperature threshold.

[0070] Among them, the temperature feedback terminal of the MCU module 102 (corresponding to the AD terminal of U102) and the output terminal of the temperature detector 105 (corresponding to Figure 2 The NTC terminal is connected to receive the temperature signal fed back by the temperature detector 105.

[0071] The MCU module 102 compares the input temperature signal with the temperature threshold, and outputs a control signal (which can be understood as a high-level signal or a low-level signal) according to the comparison result.

[0072] Furthermore, the signal input terminal of the electronic switch 103 (corresponding to the G1 terminal and the G2 terminal of U103 ) is connected to the output terminal of the MCU module 102 (corresponding to the BLUE terminal of U102 ), and is used to receive the control signal output by the MCU module 102 .

[0073] Among them, the output end of the electronic switch 103 (corresponding to the D1 end and the D2 end of U103) is connected to an input end (corresponding to the OUT- end) of the heat source main body 104, and the other input end (corresponding to the VCC end) of the heat source main body 104 is connected to the output end (corresponding to the OUT+ end) of the external power supply (or mobile power supply).

[0074] The control signal (or high level / low level) input by the MCU module 102 controls the opening or closing of the electronic switch 103 , and by controlling the on / off state of the electronic switch 103 , the working power input to the heat source body 104 is controlled.

[0075] Using this technical solution, a temperature detector 105 is set to detect the temperature signal of the component to be heated, and the temperature signal is fed back to the MCU module 102. The MCU module 102 compares the fed-back temperature signal with the temperature threshold, and controls the on / off state of the electronic switch 103 according to the comparison result, thereby controlling the heating source body 104 to heat or stop. This can effectively solve the problem in the prior art that the MCU module may not be able to control the heating of the heating component in time, causing the heating of the heating component to be delayed, resulting in poor temperature persistence and rapid temperature drop in the heated space.

[0076] In some embodiments, to improve the reliability of turning the heat source body 104 on or off, four temperature zones can be set in the heat source control module 10, specifically 43 degrees, 48 ​​degrees, 53 degrees, and 58 degrees, with each temperature zone having a temperature range of 2 degrees or 5 degrees. The details are as follows:

[0077] The temperature range of 43 degrees is controlled between 41-45 degrees;

[0078] The temperature range of 48 degrees control is between 46-50 degrees;

[0079] The temperature range of 53 degrees is controlled between 51-55 degrees;

[0080] The temperature range controlled by 58 degrees is between 56-60 degrees.

[0081] Specifically, when the temperature signal fed back by the temperature detector 105 is lower than the temperature threshold of the MCU module 102, the control signal or control instruction output by the MCU module 102 is a high level, and the control signal or control instruction is used to control the electronic switch 103 to turn on, thereby outputting working power to the heat source body 104 to control the heat source body 104 to heat the heating component;

[0082] When the temperature signal fed back by the temperature detector 105 reaches or exceeds the temperature threshold of the MCU module 102, the MCU module 102 stops outputting the control signal or outputs a low-level signal, so that the electronic switch 103 is controlled to be closed, thereby cutting off the working power of the heat source body 104, causing the heat source body 104 to be powered off and stop heating.

[0083] For example, when the temperature range of the heat source control module 10 is adjusted to 43 degrees, when the ambient temperature of the component to be heated (such as a shoe or clothing) detected by the temperature detector 105 is lower than the set temperature range (for example, lower than 43 degrees), the MCU module 102 will output a control signal or control instruction to turn on the electronic switch 103, thereby supplying power to the heat source body 104 to generate heat;

[0084] When the ambient temperature detected by the temperature detector 105 reaches or exceeds the set temperature zone, the MCU module 102 will output a control signal or a low-level signal to turn off the electronic switch 103, automatically cutting off the power supply to the heat source body 104 and stopping its power output. At this time, the device is in a zero power consumption state.

[0085] In some embodiments, in order to improve the reliability of the feedback temperature signal, a first resistor R101 may be provided at the output end of the temperature detector 105 , wherein the first resistor R101 is a pull-down resistor, and its resistance value may be selected to be 100K.

[0086] Specifically, one end of the first resistor R101 is connected to the output end (corresponding to the NTC end) of the temperature detector 105 and the temperature feedback end (corresponding to the AD end) of the MCU module 102, and the other end of the first resistor R101 is connected to the common end (corresponding to the GND end).

[0087] In some embodiments, in order to improve the safety of the operation of the power supply component 101, a first capacitor C101 can be set at the power input end of the power supply component 101 (corresponding to the INT end of U101), wherein the first capacitor C101 is used to absorb the peak voltage output by the external power supply (or mobile power supply) to prevent the peak voltage from breaking down the power supply component 101.

[0088] Specifically, one end of the first capacitor C101 is coupled to the power input end of the power supply component 101 (corresponding to the INT end of U101 ), and is used to absorb the output peak voltage.

[0089] The other end of the first capacitor C101 is connected to the common end (corresponding to the GND end).

[0090] In some embodiments, in order to improve the quality of the voltage signal input to the MCU module 102, a second capacitor C102 and a third capacitor C103 may be set at the power output end of the power supply component 101 (corresponding to the OUT end of U101), wherein the second capacitor C102 and the third capacitor C103 have a filtering function.

[0091] Specifically, the second capacitor C102 and the third capacitor C103 are connected in parallel.

[0092] Among them, one end of the second capacitor C102 and the third capacitor C103 are respectively connected to the output end of the power supply component 101 and the 3.3V power supply end, which are used to filter the voltage signal output by the power supply component 101. The filtered voltage signal is input into the power input end of the MCU module 102 (corresponding to the VDD end of U102).

[0093] The other ends of the second capacitor C102 and the third capacitor C103 are respectively connected to a common end (corresponding to the GND end).

[0094] In some embodiments, in order to improve the intuitiveness of temperature display, as Figure 2 As shown, a temperature display component 106 can be set in the heat source control module 10, which adds temperature zone values ​​within corresponding colors, provides more intuitive display and operation, and allows consumers to more directly understand the temperature range they need.

[0095] Specifically, the input end of the temperature display component 106 (corresponding to LED1-LED3) is respectively connected to the temperature zone temperature signal output end (corresponding to pin 2, pin 7 and pin 8) of the MCU module 102, which is used to display the real-time temperature inside the component to be heated detected by the temperature detector 105.

[0096] Further, such as Figure 3 As shown, the temperature display component 106 includes a first temperature display circuit 106a and a second temperature display circuit 106b, wherein the input ends of the first temperature display circuit 106a and the second temperature display circuit 106b are respectively connected to the temperature zone temperature signal output ends (corresponding to pins 2, 7 and 8) of the MCU module 102.

[0097] Specifically, the first temperature display circuit 106 a includes a second resistor R102 , a first light emitting diode (corresponding to D101 ), and a second light emitting diode (corresponding to D102 ).

[0098] The second resistor R102 is a current limiting resistor, and its resistance can be selected as 100Ω.

[0099] like Figure 2 and Figure 3 As shown, one end of the second resistor R102 (corresponding to the LED1 end) is connected to a temperature zone temperature signal output end (corresponding to pin 7) of the MCU module 102, and the other end of the second resistor R102 is respectively connected to the anodes of the first light-emitting diode (corresponding to D101) and the second light-emitting diode (corresponding to D102), the cathode of the first light-emitting diode (corresponding to D101) is connected to another temperature zone temperature signal output end (corresponding to pin 6) of the MCU module 102, and the cathode of the second light-emitting diode (corresponding to D101) is connected to a temperature zone temperature signal output end (corresponding to pin 2) of the MCU module 102. The MCU module 102 outputs a pulse signal to control the on / off of the first light-emitting diode (corresponding to D101) and the second light-emitting diode (corresponding to D102).

[0100] Furthermore, the second temperature display circuit 106b includes a third resistor R103, a third light-emitting diode (corresponding to D103) and a fourth light-emitting diode (corresponding to D104), wherein the third resistor R103 is a current-limiting resistor, and its resistance value can be selected to be 100Ω.

[0101] Specifically, one end of the third resistor R103 is connected to another temperature zone temperature signal output terminal (corresponding to pin 2) of the MCU module 102, and the other end of the third resistor R103 is respectively connected to the anodes of the third light-emitting diode (corresponding to D103) and the fourth light-emitting diode (corresponding to D104), the cathode of the third light-emitting diode (corresponding to D103) is connected to another temperature zone temperature signal output terminal (corresponding to pin 7) of the MCU module 102, and the cathode of the fourth light-emitting diode (corresponding to D104) is connected to a temperature zone temperature signal output terminal (corresponding to pin 6) of the MCU module 102. The MCU module 102 outputs a pulse signal to control the on / off of the third light-emitting diode (corresponding to D103) and the fourth light-emitting diode (corresponding to D104).

[0102] In some embodiments, in order to improve the convenience of controlling start / stop, a start switch 107 can be set in the heat source control module 10, wherein the output end of the start switch 107 (corresponding to pins 1 and 4 of the switch S101) is connected to the switch signal input end (corresponding to the KEY end) of the MCU module 102, which is used to receive an external input control trigger signal, and the MCU module 102 controls the opening of the electronic switch 103 through the input trigger signal.

[0103] Specifically, when the system is fully installed, the battery supplies energy to the entire system. When the user starts the system, the system will monitor the ambient temperature of the heating area in real time. At the same time, the temperature detector 105 will feed the collected real-time temperature signal back to the MCU module 102. The MCU module 102 will compare the received temperature signal with the pre-set temperature parameters of the temperature zone, identify the difference between the ambient temperature and the set temperature, and take appropriate measures. After the system is turned on, it will continue to repeat the detection and adjustment to achieve the purpose of maintaining a constant temperature range.
