[0012] The conversion module is connected to both the power supply and the processing module.

[0013] The conversion module is used to receive the power supply voltage, convert the power supply voltage into a working voltage, and transmit the working voltage to the processing module for power supply.

[0014] In one embodiment, the circuit further includes: a button module;

[0015] The button module is connected to the processing module;

[0016] The button module is used to transmit the generated power-on signal to the processing module when it is pressed.

[0017] The processing module is further configured to transmit the generated conduction signal to the switching module when the power-on signal is received, so that the switching module transmits the power supply voltage to the heating wire for power supply.

[0018] In one embodiment, the button module is further configured to transmit the generated power-down signal to the processing module when the button is pressed again;

[0019] The processing module is further configured to transmit the generated disconnect signal to the switching module when the power-off signal is received, so that the switching module stops transmitting the power supply voltage to the heating wire for power supply.

[0032] In addition, to achieve the above objectives, this utility model also proposes a heated garment, which includes the intelligent control circuit described above.

[0033] This utility model proposes an intelligent control circuit and a heated garment. The circuit includes: a switching module connected to a power supply and a heating wire, used to transmit the power supply voltage provided by the power supply to the heating wire for heating; a data acquisition module connected to the connection point between the power supply and the switching module, used to acquire the voltage value of the power supply to generate a voltage signal, and / or, used to acquire the current value of the power supply to generate a current signal; and a processing module connected to the data acquisition module and the switching module, used to receive the voltage signal and the current signal, determine the current resistance value, the voltage value, and the current value, and generate a disconnect signal and transmit it to the switching module when one of the current resistance value, voltage value, and current value is higher than a corresponding preset threshold, so that the switching module stops transmitting the power supply voltage to the heating wire for heating.

[0034] This invention comprises a data acquisition module, a switching module, and a processing module. The data acquisition module collects the voltage and current values ​​transmitted from the power supply and generates voltage and current signals, which are then transmitted to the processing module. The processing module determines the current resistance, voltage, and current values ​​based on these signals. Since one of these three values ​​increases when the heating wire is disconnected, the processing module generates a disconnection signal and transmits it to the switching module when any of these values ​​exceeds a preset threshold. Upon receiving the disconnection signal, the switching module disconnects the power supply from the heating wire, thus stopping power supply to the heating wire. Therefore, this invention can stop supplying power to the heating wire if it is accidentally disconnected or intentionally cut off, improving safety. Attached Figure Description

[0048] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0050] 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.

[0051] 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.

[0052] Furthermore, the use of terms such as "first" and "second" in this utility model is 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 as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this utility model.

[0053] It should be noted that currently, most existing clothing has a heating function. Specifically, a heating wire 3 can be installed inside the clothing, and a power supply 1 supplies power to the heating wire 3 to generate heat, thereby heating the clothing.

[0054] However, if the heating wire 3 is accidentally disconnected or cut off by human intervention, continuing to supply power to the heating wire 3 may easily lead to high temperature, sparks or fire, resulting in poor safety.

[0055] To address the aforementioned technical issues, this embodiment includes a data acquisition module 5, a switch module 2, and a processing module 4. The data acquisition module 5 acquires the voltage and current values ​​transmitted from the power supply 1 and generates voltage and current signals, which are then transmitted to the processing module 4. The processing module 4 determines the current resistance, voltage, and current values ​​based on these signals. Since one of the three values ​​(resistance, current, and voltage) increases when the heating wire 3 is disconnected, the processing module 4 generates a disconnection signal and transmits it to the switch module 2 when any one of these values ​​exceeds a preset threshold. Upon receiving the disconnection signal, the switch module 2 disconnects the power supply 1 from the heating wire 3, thus stopping power supply to the heating wire 3. Therefore, this embodiment can stop supplying power to the heating wire 3 if it is accidentally disconnected or manually cut off, improving safety.

[0056] For ease of understanding, the following is combined with Figures 1 to 9 The intelligent control circuit provided in the embodiments of this utility model will be described in detail.

[0057] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the intelligent control circuit proposed in this utility model.

[0058] like Figure 1 As shown, in this embodiment, the circuit includes:

[0059] The switch module 2 is connected to the power supply 1 and the heating wire 3 respectively, and is used to transmit the power supply voltage provided by the power supply 1 to the heating wire 3 for power supply and heating.

[0060] The acquisition module 5 is connected to the connection point between the power supply 1 and the switch module 2, and is used to acquire the voltage value of the power supply to generate a voltage signal, and / or to acquire the current value of the power supply to generate a current signal.

[0061] The processing module 4 is connected to the acquisition module 5 and the switch module 2 respectively. It is used to receive the voltage signal and the current signal, determine the current resistance value, the voltage value and the current value, and generate a disconnect signal when one of the current resistance value, voltage value and current value is higher than the corresponding preset threshold. The signal is then transmitted to the switch module 2 so that the switch module 2 stops transmitting the power supply voltage to the heating wire 3 for power supply.

[0062] It should be noted that the intelligent control circuit in this embodiment can be applied to any scenario where an abnormality occurs, leading to an increase in resistance. For example, in a heated suit, the heating wire 3 may break, causing a fire. This embodiment uses the heating wire 3 in the heated suit for illustration, but it does not limit the application of this method.

[0063] It should also be noted that the heating wire 3 in this embodiment can be any device used for heating, and multiple sets of heating wires 3 can be set in the heated clothing in this embodiment. Each heating wire 3 can be connected in series. The specific number of sets of heating wires 3 is not limited in this embodiment.

[0064] It is understood that the power supply 1 can be any power source that supplies power to the heating wire 3. In this embodiment, the power supply 1 can provide a power supply voltage to the heating wire 3 so that the heating wire 3 is powered on and heated. The magnitude of the power supply voltage in this embodiment can be set according to the actual situation. This embodiment does not limit this, but for ease of subsequent understanding, this embodiment uses 8.6V to 12.6V for explanation.

[0065] It is also understood that the aforementioned switch module 2 can be any module used for switching on and off control, such as a switching transistor. In actual use, the switch module 2 can be in the conducting state, and the power supply 1 can transmit the supply voltage to the switch module 2, which then transmits it to the heating wire 3 for heating.

[0066] It should be understood that the acquisition module 5 can be a module for acquiring current and voltage. In this embodiment, the acquisition module 5 can be connected to the connection point between the power supply 1 and the switch module 2, and can acquire the current value of the power supply transmitted to the switch module 2 and generate the current signal, acquire the voltage value of the power supply transmitted to the switch module 2 and generate the voltage signal, and then transmit both the current signal and the voltage signal to the processing module 4.

[0067] It should also be understood that the above-mentioned processing module 4 can be any module with processing functions, such as a microcontroller (MCU), etc. This embodiment uses an MCU for illustration.

[0068] In actual use, when the processing module 4 receives the current signal and the voltage signal, it can determine the current resistance value, voltage value and current value based on the current signal and the voltage signal. The current resistance value can be the resistance value of all loads after the connection point between the power supply 1 and the switching module 2, specifically the resistance value of the switching module 2 and the heating wire 3. Since one of the resistance, current, and voltage values ​​increases when the heating wire 3 is disconnected, the processing module 4 can compare the current resistance, voltage, and current values ​​with corresponding preset thresholds. If none of the three values ​​exceed the preset threshold, it indicates that the heating wire 3 is not disconnected, and the processing module 4 outputs no disconnection signal. The switch module 2 remains on, and the power supply 1 continues to supply power to the heating wire 3. If any of the three values ​​exceeds the preset threshold, it indicates that the heating wire 3 is disconnected, and the processing module 4 outputs a disconnection signal to the switch module 2. The switch module 2 then remains off, stopping the transmission of power supply voltage to the heating wire 3. The heating wire 3 stops working, thus preventing high temperatures, sparks, or fires, and improving safety.

[0069] It should be emphasized that the aforementioned preset thresholds can be set according to actual conditions, and this embodiment does not impose any restrictions on them. The current resistance value can be set with a corresponding preset resistance threshold, the current value can be set with a corresponding preset current threshold, and the voltage value can be set with a corresponding preset voltage threshold.

[0070] Furthermore, in order to obtain the current resistance value, in this embodiment, the processing module 4 is also used to receive the current signal, determine the voltage value of the power supply, and receive the current signal to determine the current value of the power supply.

[0071] The processing module 4 is further configured to determine the current resistance value after determining the voltage value and the current value of the power supply.

[0072] It should be noted that since the above-mentioned power supply voltage is the voltage flowing through the switch module 2 and the heating wire 3, the voltage value of the above-mentioned power supply can be the voltage value transmitted to the switch module 2 and the heating wire 3, and the current value of the above-mentioned power supply can be the current value transmitted to the switch module 2 and the heating wire 3.

[0073] In actual use, after receiving a current signal, the processing module 4 can determine the current value based on the current signal. After receiving a voltage signal, it can determine the voltage value based on the voltage signal. Then, by using Ohm's law, the current resistance value can be obtained based on the current value and the voltage value.

[0074] Furthermore, considering that higher temperatures could easily cause the heated clothing to catch fire, leading to lower safety, therefore, continuing as follows... Figure 1As shown, in this embodiment, the circuit further includes a temperature detection module 6;

[0075] The temperature detection module 6 is connected to the processing module 4;

[0076] The temperature detection module 6 is used to collect the current temperature and transmit the generated temperature signal to the processing module 4;

[0077] The processing module 4 is further configured to determine the current temperature when the temperature signal is received, and transmit the generated disconnect signal to the switch module 2 when the current temperature is higher than a preset temperature threshold.

[0078] It should be noted that the temperature detection module 6 mentioned above can be any module used to collect temperature, such as a temperature sensor, and this embodiment does not limit it.

[0079] It should also be noted that, in this embodiment, to improve safety, the temperature detection module 6 can be positioned close to the heating wire 3. This allows it to collect the temperature near the heating wire 3, which is then used as the current temperature and transmitted to the processing module 4 as a temperature signal.

[0080] After receiving the temperature signal, the processing module 4 can obtain the current temperature based on the temperature signal and compare the current temperature with the preset temperature threshold. If the current temperature is not higher than the preset temperature threshold, it means that the temperature is not high and heating can continue. In this case, the processing module 4 does not transmit a disconnect signal to the switch module 2, and the switch module 2 remains on. When the temperature is higher than the preset temperature threshold, it means that the temperature is too high and heating needs to be stopped immediately. Then the processing module 4 can output a disconnect signal to the switch module 2 to disconnect the switch module 2.

[0081] This embodiment includes a data acquisition module 5, a switch module 2, and a processing module 4. The data acquisition module 5 acquires the voltage and current values ​​transmitted from the power supply 1 and generates voltage and current signals, which are then transmitted to the processing module 4. The processing module 4 determines the current resistance, voltage, and current values ​​based on these signals. Since one of the three values ​​increases when the heating wire 3 is disconnected, the processing module 4 generates a disconnection signal and transmits it to the switch module 2 when any of these values ​​exceeds a preset threshold. Upon receiving the disconnection signal, the switch module 2 disconnects the power supply 1 from the heating wire 3, thus stopping the power supply to the heating wire 3. Therefore, this embodiment can stop supplying power to the heating wire 3 if it is accidentally disconnected or manually cut off, improving safety.

[0082] Reference Figure 2 , Figure 2This is a schematic diagram of the structure of the second embodiment of the intelligent control circuit proposed in this utility model.

[0083] Based on the above embodiments, a second embodiment of this utility model is proposed. In order to collect current values ​​and voltage values, as follows... Figure 2 As shown, in this embodiment, the acquisition module 5 includes: a current acquisition unit 52 and a voltage acquisition unit 51;

[0084] The current acquisition unit 52 is connected to the connection points between the processing module 4, the power supply 1, and the switch module 2, respectively; the voltage acquisition module 5 is connected to the connection points between the processing module 4, the power supply 1, and the switch module 2, respectively.

[0085] The current acquisition unit 52 is used to acquire the current value of the power supply, generate a current signal, and transmit the current signal to the processing module 4.

[0086] The voltage acquisition unit 51 is used to acquire the voltage value of the power supply, generate a voltage signal, and transmit the voltage signal to the processing module 4.

[0087] It should be noted that the current acquisition unit 52 described above can be any unit used for acquiring current, such as a shunt circuit, etc., and this embodiment does not impose any restrictions on it. The voltage acquisition unit 51 described above can be any unit used for acquiring voltage, such as a voltage divider circuit, etc., and this embodiment does not impose any restrictions on it.

[0088] In actual use, the current acquisition unit 52 can acquire the current value of the power supply and generate a current signal to be transmitted to the processing module 4, and the voltage acquisition unit 51 can acquire the voltage value of the power supply and generate a voltage signal to be transmitted to the processing module 4.

[0089] It is important to emphasize that, since fires are more likely to occur when the current or voltage value of the power supply is high, in this embodiment, the processing module 4 can, after obtaining the current and voltage values ​​of the power supply, compare the current value with a preset current threshold. If the current value is not higher than the preset current threshold, it indicates that the current is low, and therefore no disconnection signal is generated, and the switch module 2 continues to supply power. If the current value is higher than the preset current threshold, it indicates that the current is high, and therefore a disconnection signal is generated to the switch module 2 to control the switch module 2 to disconnect, further improving safety. The preset current threshold can be set according to actual conditions, and this embodiment does not impose any restrictions on it.

[0090] Similarly, the voltage value can be compared with a preset voltage threshold. If it is higher, a disconnection signal is generated; if it is not higher, no disconnection signal is generated. The specific process is the same as that for comparing current values, and this embodiment will not elaborate on it.

[0091] Furthermore, in order to supply power to processing module 4, such as Figure 2 As shown, in this embodiment, the circuit further includes: a conversion module 7;

[0092] The conversion module 7 is connected to the power supply 1 and the processing module 4 respectively;

[0093] The conversion module 7 is used to receive the power supply voltage, convert the power supply voltage into a working voltage, and transmit the working voltage to the processing module 4 for power supply.

[0094] It should be noted that the aforementioned conversion module 7 can be any module used for voltage conversion, such as voltage conversion chip U2, etc., and this embodiment does not impose any restrictions on it. The aforementioned operating voltage can be the voltage provided to the processing module 4 for power supply. In this embodiment, 5V is used as the voltage required for the operation of the processing module 4, but this is not a limitation.

[0095] In actual use, the power supply 1 can also transmit the power supply voltage of 8.6V to 12.6V to the conversion module 7, which can convert it to 5V as the above-mentioned working voltage and transmit the working voltage to the processing module 4 for power supply.

[0096] It should be emphasized that since the conversion module 7 is connected to the power supply 1 to receive the power supply voltage, the voltage acquisition unit 51 can be connected to the conversion module 7, and can directly obtain the corresponding voltage value by inputting the power supply voltage to the conversion module 7.

[0097] Furthermore, for the on / off function, refer to Figure 3 , Figure 3 This is a circuit diagram of the switch module 2 and the current acquisition unit 52 in the second embodiment of the intelligent control circuit proposed in this utility model; as shown below. Figure 3 As shown, in this embodiment, the switch module 2 includes: a switch chip U1, a first resistor R1, and a second resistor R2;

[0098] The first input terminal (first pin of switch chip U1) is connected to the second input terminal (second pin of switch chip U1), the third input terminal (third pin of switch chip U1), the current acquisition module 5, and the power supply 1 (i.e., Figure 3 The control terminal (pin 4 of switch chip U1) of switch chip U1 is connected to the second terminal of the first resistor R1 and the first terminal of the second resistor R2, respectively. The second terminal of the second resistor R2 is grounded. The first terminal of the first resistor R1 is connected to the processing module 4 (i.e., VBAT). Figure 3The PWM1 is connected, and the first output terminal (pin 5 of switch chip U1) is connected to the second output terminal (pin 6 of switch chip U1), the third output terminal (pin 7 of switch chip U1), the fourth output terminal (pin 8 of switch chip U1), and the heating wire 3 (i.e., Figure 3 Connect VOUT.

[0099] It is understood that the aforementioned switch chip U1 can be any chip that implements switch control, such as the SL4406, or other models. This embodiment does not limit this.

[0100] In practical use, when the control terminal of switch chip U1 does not receive a disconnect signal, switch chip U1 remains on, thereby allowing the supply voltage from power supply 1 to be transmitted to the first input terminal to the third input terminal of switch chip U1, and output from the first output terminal to the fourth output terminal of switch chip U1 to the heating wire 3. Simultaneously, the first output terminal of switch chip U1 can also transmit the supply voltage to the current acquisition unit 52 for current acquisition.

[0101] Furthermore, in order to achieve current acquisition, such as Figure 3 As shown, in this embodiment, the current acquisition unit 52 includes: a first capacitor C1 and a third resistor R3 to a fifth resistor R5;

[0102] The first input terminal of the switch chip U1 is connected to the second terminals of the third resistor R3, the fourth resistor R4, and the fifth resistor R5, respectively. The first terminal of the fourth resistor R4 is connected to the first terminal of the fifth resistor R5, and the first terminal of the fourth resistor R4 is also grounded. The first terminal of the third resistor R3 is connected to the second terminal of the first capacitor C1 and the processing module 4 (i.e., Figure 3 (AD) connection.

[0103] It should be understood that the aforementioned fourth resistor R4 and fifth resistor R5 can be alloy circuits used to sample the current of the power supply. Furthermore, in actual use, the first input terminal of the switching chip U1 can transmit the power supply voltage to the fourth resistor R4 and the fifth resistor R5 for shunting, and simultaneously transmit it to the processing module 4 via the third resistor R3. The processing module 4 can then receive the current signal and determine the current value.

[0104] Furthermore, in order to achieve a working voltage of 5V, refer to... Figure 4 , Figure 4 The circuit diagram of the conversion module 7 in the second embodiment of the intelligent control circuit proposed in this utility model is shown.

[0105] like Figure 4As shown, in this embodiment, the conversion module 7 includes: a conversion chip U2, a first diode D1, a second diode D2, a second capacitor C2, and a third capacitor C3;

[0106] The input terminal of the conversion chip U2 (the third pin of the conversion chip U2) is connected to the voltage acquisition unit 51 (i.e., Figure 4 The cathode of the first diode D1, the cathode of the second diode D2, the first terminal of the second capacitor C2, and the cathode of the first diode D1 are connected together. The second terminal of the second capacitor C2 is grounded. The anode of the first diode D1 is connected to the power supply 1 (i.e., U1_VDD). Figure 4 The ground terminal (first pin of converter chip U2) of converter chip U2 is connected to the anode of the second diode D2. The ground terminal of converter chip U2 is also grounded. The output terminal (second pin of converter chip U2) of converter chip U2 is connected to the first terminal of the second capacitor C2 and the processing module 4 (i.e., VBAT). Figure 4 Connect to 5V.

[0107] It should be noted that the aforementioned conversion chip U2 can be any chip that implements voltage conversion function, such as the 7550 model, etc., and this embodiment does not impose any restrictions on it. The aforementioned first diode D1 can be a Schottky diode, and the aforementioned second diode D2 can be an anti-static diode.

[0108] In practical use, the supply voltage of power supply 1 can be transmitted to conversion chip U2 through the first diode D1 for conversion. The output terminal of conversion chip U2 can output a stable 5V working voltage and transmit it to processing module 4. The cathode of the first diode D1 can also transmit the supply voltage to voltage acquisition unit 51 for voltage value acquisition.

[0109] It should be emphasized that the first diode D1 is used to prevent components from being burned out due to reverse soldering during the process, and the second diode D2 is used to prevent components from being damaged by static electricity generated by external contact through the metal part of the power connector. This power connector can be a connector used to connect to power supply 1.

[0110] Furthermore, in order to achieve voltage acquisition, refer to Figure 5 , Figure 5 This is a circuit diagram of the voltage acquisition unit 51 in the second embodiment of the intelligent control circuit proposed in this utility model.

[0111] like Figure 5 As shown, in this embodiment, the voltage acquisition unit 51 includes: a sixth resistor R6, a seventh resistor R7, and a fourth capacitor C4.

[0112] The first terminal of the sixth resistor R6 is connected to the input terminal of the conversion chip U2 (i.e. Figure 4The second terminal of the sixth resistor R6 is connected to the first terminal of the seventh resistor R7, the first terminal of the fourth capacitor C4, and the processing module 4 (i.e., U1_VDD). Figure 4 The BAT_AD is connected in the middle. The second end of the seventh resistor R7 is connected to the second end of the fourth capacitor C4. The second end of the seventh resistor R7 is also grounded.

[0113] It should be noted that in this embodiment, the voltage value of the power supply can be collected by voltage division through the sixth resistor R6 and the seventh resistor R7, and the voltage signal generated can be transmitted to the processing module 4 through the second end of the sixth resistor R6.

[0114] Furthermore, in order to realize the function of processing module 4, refer to Figure 6 , Figure 6 The circuit diagram of the processing module 4 in the second embodiment of the intelligent control circuit proposed in this utility model embodiment;

[0115] like Figure 6 As shown, in this embodiment, the processing module 4 includes: a processing chip U3 and a fifth capacitor;

[0116] The power supply terminal of processing chip U3 (the first pin of processing chip U3) is connected to the output terminal of conversion chip U2 (i.e., Figure 6 The first terminal of the fifth capacitor is connected to the 5V input, the second terminal of the fifth capacitor is grounded, and the control terminal of the processing chip U3 (pin 7 of the processing chip U3) is connected to the first terminal of the first resistor R1 (i.e., 5V). Figure 6 The PWM1 is connected to the current acquisition terminal (pin 8 of the processing chip U3) of the processing chip U3 and the first terminal (i.e., the first terminal of the third resistor R3). Figure 6 The voltage acquisition terminal of the processing chip U3 (pin 13 of the processing chip U3) is connected to the second terminal of the sixth resistor R6 (i.e., the voltage acquisition terminal of the processing chip U3 is connected to the second terminal of the sixth resistor R6). Figure 6 Connect BAT_AD to the ground terminal of the processing chip U3 (pin 14 of the processing chip U3).

[0117] It is understood that the aforementioned processing chip U3 can be any chip with processing capabilities, such as an MCU, and this embodiment does not impose any restrictions on it.

[0118] In actual use, the power supply terminal of the processing chip U3 is used to receive a 5V working voltage, the current acquisition terminal of the processing chip U3 is used to receive current signals, the voltage acquisition terminal of the processing chip U3 is used to receive voltage signals, and the control terminal of the processing chip U3 is used to output a disconnect signal.

[0119] Reference Figure 7 , Figure 7 This is a schematic diagram of the third embodiment of the intelligent control circuit proposed in this utility model.

[0120] Based on the above embodiments, a third embodiment of the present invention is proposed. To control the opening and closing of the heating wire 3, i.e., to control whether the heating wire 3 is working, as follows... Figure 7 As shown, in this embodiment, the circuit further includes a button module 8;

[0121] The button module 8 is connected to the processing module 4;

[0122] The button module 8 is used to transmit the generated power-on signal to the processing module 4 when it is pressed.

[0123] The processing module 4 is further configured to transmit the generated conduction signal to the switch module 2 when the power-on signal is received, so that the switch module 2 transmits the power supply voltage to the heating wire 3 for power supply.

[0124] It should be noted that the button module 8 mentioned above can be any module used to interact with the user (specifically, it can be pressed by the user) to realize signal input, such as a button, etc. This embodiment does not limit it.

[0125] In actual use, when the user needs to heat, the button module 8 can be pressed. When the button module 8 is pressed, it can generate a power-on signal to the processing module 4. After receiving the power-on signal, the processing module 4 can output a conduction signal to the switch module 2. The switch module 2 then conducts the path between the power supply 1 and the heating wire 3, thereby transmitting the power supply voltage to the heating wire 3 for power supply and heating.

[0126] Furthermore, in order to turn off the heating wire 3, in this embodiment, the button module 8 is also used to transmit the generated power-down signal to the processing module 4 when it is pressed again;

[0127] The processing module 4 is further configured to transmit the generated disconnect signal to the switch module 2 when the power-off signal is received, so that the switch module 2 stops transmitting the power supply voltage to the heating wire 3 for power supply.

[0128] Understandably, when the user needs to turn off the heating, they can press the button module 8 again. After the button module 8 is pressed again, it can generate a power-down signal to the processing module 4. The processing module 4 can then generate a disconnect signal to the switch module 2. After receiving the disconnect signal, the switch module 2 can disconnect the power supply 1 from the heating wire 3, thereby stopping the power supply to the heating wire 3.

[0129] Furthermore, in order to implement button module 8, refer to Figure 8 , Figure 8 The circuit diagram of the button module 8 in the third embodiment of the intelligent control circuit proposed in this utility model embodiment;

[0130] like Figure 8 As shown, in this embodiment, the button module 8 includes: a first button K1;

[0131] The first end of the first button K1 is connected to the button end of the processing chip U3 (i.e. Figure 8 The middle KEY (i.e., the twelfth pin of the processing chip U3) is connected, and the second end of the first button K1 is grounded.

[0132] In practical use, it can be set to operate at a low level. When the user presses the first button K1 once, the first button K1 is grounded, pulling the level low, thereby generating a power-on signal and transmitting it to the processing chip U3. Upon receiving the power-on signal, the processing chip U3 determines that the heating wire 3 needs to work, and thus generates a conduction signal, which is transmitted to the switch chip U1 through the control terminal of the processing chip U3, thereby turning on the switch chip U1. When the user presses the first button K1 again, a power-off signal is generated and transmitted to the processing chip U3. The processing chip U3 then determines that the user does not need heating, and thus generates a disconnect signal and transmits it to the switch chip U1, thereby turning off the switch chip U1.

[0133] Furthermore, in order to prompt the user when the heating wire 3 is disconnected, in this embodiment, the process continues as follows: Figure 7 As shown, the circuit also includes: a display module 9;

[0134] The display module 9 is connected to the processing module 4;

[0135] The processing module 4 is also used to transmit the generated alarm signal to the display module 9 when one of the current resistance value, the voltage value, and the current value is higher than the corresponding preset threshold.

[0136] The display module 9 is used to display an alarm when the alarm signal is received.

[0137] It should be noted that the above-mentioned display module 9 can be any module used for display, such as light-emitting diodes, etc., and this embodiment does not limit it.

[0138] In actual use, when the processing module 4 determines that one of the current resistance value, voltage value, and current value is higher than the corresponding preset threshold, it can generate an alarm signal and transmit it to the display module 9. After receiving the alarm signal, the display module 9 can display the alarm. For example, the display module 9 is equipped with a light-emitting diode that emits red light, so that the display module 9 flashes red light.

[0139] Furthermore, for the purpose of display, refer to Figure 9 , Figure 9 The circuit diagram of the display module 9 in the third embodiment of the intelligent control circuit proposed in this utility model embodiment;

[0140] like Figure 9 As shown, in this embodiment, the display module 9 includes: a first tri-color light-emitting diode (LED1) to a fourth tri-color light-emitting diode (LED4) and an eighth resistor (R8) to a nineteenth resistor (R19);

[0141] The first terminal of the first tri-color light-emitting diode LED1 is connected to the output terminal of the conversion chip U2 (i.e., Figure 9 The first three-color LED (LED1) is connected to the 5V terminal, and the second terminal of the first three-color LED is connected to the first terminal of the tenth resistor R10. The second terminal of the tenth resistor R10 is connected to the first light-emitting terminal of the processing chip U3 (i.e., the 5V terminal). Figure 9 The first tri-color LED (LED1, i.e., the sixth pin of the processing chip U3) is connected. The third terminal of the first tri-color LED1 is connected to the first terminal of the ninth resistor R9. The second terminal of the ninth resistor R9 is connected to the second light-emitting terminal of the processing chip U3 (i.e., the second terminal of the processing chip U3). Figure 9 LED2 (i.e., the fifth pin of the processing chip U3) is connected to the first terminal of the first tri-color LED1, and the second terminal of the eighth resistor R8 is connected to the third terminal of the processing chip U3 (i.e., the fifth pin of the processing chip U3). Figure 9 Connect LED3 (which is the second pin of the processing chip U3);

[0142] The first terminal of the second tri-color light-emitting diode LED2 is connected to the output terminal of the conversion chip U2 (i.e. Figure 9 The second terminal of the second tri-color LED2 is connected to the first terminal of the thirteenth resistor R13, and the second terminal of the thirteenth resistor R13 is connected to the first light-emitting terminal of the processing chip U3 (i.e., 5V). Figure 9 Connect LED1 (which is the sixth pin of the processing chip U3) to the first pin of the second tri-color LED (LED2). Connect the third pin of the second tri-color LED (LED2) to the first pin of the twelfth resistor R12. Connect the second pin of the twelfth resistor R12 to the second light-emitting pin of the processing chip U3 (i.e., the second pin of the third tri-color LED). Figure 9 The second tri-color LED (LED2, i.e., the fifth pin of the processing chip U3) is connected to the third light-emitting terminal (i.e., the fourth terminal of the second tri-color LED2 is connected to the first terminal of the eleventh resistor R11, and the second terminal of the eleventh resistor R11 is connected to the third light-emitting terminal of the processing chip U3. Figure 9 Connect LED3 (which is the second pin of the processing chip U3);

[0143] The first terminal of the third tri-color light-emitting diode LED3 is connected to the output terminal of the conversion chip U2 (i.e. Figure 9 The 5V input is connected to the first terminal of the third tri-color LED3, which is connected to the first terminal of the sixteenth resistor R16. The second terminal of the sixteenth resistor R16 is connected to the first light-emitting terminal of the processing chip U3 (i.e., the 5V input). Figure 9Connect LED1 (the sixth pin of the processing chip U3) to the third tri-color LED. Connect the third terminal of LED3 to the first terminal of the fifteenth resistor R15. Connect the second terminal of the fifteenth resistor R15 to the second light-emitting terminal of the processing chip U3 (i.e., the second terminal of the processing chip U3). Figure 9 The third tri-color LED (LED2, i.e., the fifth pin of the processing chip U3) is connected to the fourth pin of the third tri-color LED (LED3). The fourth pin of the third tri-color LED (LED3) is connected to the first pin of the fourteenth resistor R14. The second pin of the fourteenth resistor R14 is connected to the third light-emitting pin of the processing chip U3 (i.e., the fifth pin of the processing chip U3). Figure 9 Connect LED3 (which is the second pin of the processing chip U3);

[0144] The first terminal of the fourth tri-color light-emitting diode LED4 is connected to the output terminal of the conversion chip U2 (i.e. Figure 9 The 5V terminal is connected to the first terminal of the nineteenth resistor R19, and the second terminal of the nineteenth resistor R19 is connected to the first light-emitting terminal of the processing chip U3 (i.e., the 5V terminal). Figure 9 LED1 (i.e., pin 6 of processing chip U3) is connected to the first terminal of the fourth tri-color LED (LED4), and the second terminal of the eighteenth resistor R18 is connected to the second light-emitting terminal of processing chip U3 (i.e.,...). Figure 9 LED2 (i.e., the fifth pin of the processing chip U3) is connected; the fourth terminal of the fourth tri-color LED4 is connected to the first terminal of the seventeenth resistor R17; and the second terminal of the seventeenth resistor R17 is connected to the third light-emitting terminal of the processing chip U3 (i.e., the... Figure 9 Connect LED3 (which is the second pin of the processing chip U3).

[0145] In actual use, when the processing chip U3 generates an alarm signal, the alarm signal can be transmitted to the first tri-color LED1 to the fourth tri-color LED4 through the first light-emitting terminal of the processing chip U3. That is, the pin is intermittently pulled low and placed at a low level, and the 5V power supply is turned on, so that the red light in the first tri-color LED1 to the fourth tri-color LED4 flashes (i.e., R flashes).

[0146] Furthermore, considering that users have different heating needs, in this embodiment, the processing module 4 is also used to transmit the generated gear signal to the switching module 2;

[0147] The switch module 2 is also used to adjust the power supply voltage when receiving the gear position signal, and transmit the adjusted power supply voltage to the heating wire 3 for power supply.

[0148] Understandably, the aforementioned gear signal can be used to adjust the conduction level of the switch module 2, and can characterize the current gear level of the heating wire 3. In this embodiment, three gear levels can be set, including low, medium, and high, with the heat generated by the heating wire 3 increasing sequentially from low to high.

[0149] It is also understood that in this embodiment, gear control can also be performed through the aforementioned button module 8. For example, control can be performed based on the duration of the user's long press, and of course, an additional button can be provided for adjusting the gear, etc., but this embodiment does not impose any limitations on this.

[0150] In actual use, when the user presses the gear position, combined with... Figure 6 The processing chip U3 can generate a gear position signal and transmit it to the switching chip U1 through the control terminal of the processing chip U3, combined with Figure 3 After receiving the gear position signal, the first resistor R1 can transmit it to the control terminal of the switch chip U1, thereby adjusting the conduction level of the switch chip U1, and then adjusting the current of the power supply transmitted to the heating wire 3 to achieve gear position adjustment.

[0151] Furthermore, in order to help users understand the current gear position, the processing module 4 is also used to transmit the generated gear position display signal to the display module 9;

[0152] The display module 9 is used to display the gear position when it receives the gear position display signal.

[0153] It should be noted that the aforementioned gear position display signal can be used to display the current gear position. In actual use, the processing module 4 can generate a gear position display signal and transmit it to the display module 9, which then displays the gear position.

[0154] Combination Figure 9 The processing chip U3 can control different light-emitting terminals to output display signals to show different light levels. For example, the first light-emitting terminal of the processing chip U3 can output a display signal to indicate a high light level, causing the red light in the first tri-color LED1 to the fourth tri-color LED4 to be constantly lit (i.e., R is constantly lit). The third light-emitting terminal of the processing chip U3 can output a display signal to indicate a medium light level, causing the blue light in the first tri-color LED1 to the fourth tri-color LED4 to be constantly lit (i.e., B is constantly lit). The second light-emitting terminal of the processing chip U3 can output a display signal to indicate a low light level, causing the green light in the first tri-color LED1 to the fourth tri-color LED4 to be constantly lit (i.e., G is constantly lit).
