Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning clothing control, and in particular to a control system for cooling and heating air-conditioning clothing. Background Art

[0002] Early clothing relied on passive insulation (such as heavy cotton clothing or light, breathable fabrics) to regulate temperature, but was unable to proactively adapt to extreme environments. For example, in high-temperature environments, outdoor workers (such as traffic police and construction workers) face the risk of heatstroke, and traditional clothing, solely through moisture wicking, is ineffective in cooling them down. In low-temperature environments, working in extreme cold requires layering, limiting mobility. With the expansion of outdoor sports and specialized operations (military and medical), air-conditioned clothing has emerged. However, current air-conditioned clothing only provides single-purpose temperature regulation, lacks intelligent temperature control, and requires a bulky external power supply, making it difficult to port.

[0003] For example, although the Chinese patent publication number CN220654812U relates to an air-cooled air-conditioning suit, a refrigeration unit and a fan are arranged outside the suit body to effectively reduce the expansion of the suit during operation, thereby improving the flexibility and wearing comfort during operation; however, it does not involve specific control means and cannot solve the above-mentioned technical problems. Summary of the Invention

[0042] By controlling the first transistor Q1 , the second transistor Q2 and the third transistor Q3 , the lighting of each group of diodes of the same color can be independently adjusted.

[0043] refer to Figure 1 and Figure 4 , the microprocessor of the control module is also connected to the mobile power supply 300, specifically, the microprocessor is connected to the mobile power supply via a connecting wire 301; Figure 2 Two filter capacitors are also provided between the mobile power supply and the microprocessor. The two filter capacitors are connected in parallel with one end of the filter capacitor being grounded.

[0044] In this embodiment, the control module is a control board, and the control board is provided with a USB interface. In this embodiment, the USB interface is of TYPE-A type. The mobile power supply is connected to the control board via a two-core wire in the form of a USB interface (TYPE-A), and the semiconductor refrigeration unit is connected to the control board in parallel via a three-core wire.

[0045] The mobile power supply in this embodiment can provide stable power for the control system. Its parameters are voltage output 5V and maximum output current 3A. It is connected to the control board through the USB interface to provide power for the system.

[0046] In this technical solution, two filter capacitors are connected in parallel, namely capacitor C1 and capacitor C2. The function of the two filter capacitors is to filter the power supply, stabilize the voltage, and prevent voltage fluctuations from affecting the operation of the microcontroller and other components.

[0047] In more detail, one end of capacitor C1 is connected to the DC 5V voltage terminal, the other end of capacitor C1 is grounded, one end of capacitor C2 is connected to the DC 5V voltage terminal, the other end of capacitor C2 is grounded, and one end of capacitor C1 is connected to one pin of the microprocessor, and the other end of capacitor C2 is connected to another pin of the microprocessor.

[0048] The semiconductor transistor circuit mainly includes a plurality of semiconductor transistors, which are connected to form an H-bridge circuit. The gate of each semiconductor transistor is connected to the microprocessor via a third resistor.

[0049] The third resistor includes a resistor R8 , a resistor R9 , a resistor R10 , and a resistor R11 .

[0050] Specifically, the semiconductor transistor circuit includes a fourth transistor Q4, the gate of which is connected to the refrigeration unit, the source of which is connected to the drain of a fifth transistor Q5, and the source of which is grounded. A resistor R8 is further provided between the source of the fourth transistor Q4 and the refrigeration unit, and the gate of the fifth transistor Q5 is connected to the refrigeration unit via a resistor R9.

[0051] In addition, a gate of the fifth transistor Q5 is connected to the resistor R12 , and the other end of the resistor R12 is grounded.

[0052] Similarly, the semiconductor transistor circuit includes a sixth transistor Q6, the gate of which is connected to the refrigeration unit, the source of which is connected to the drain of the seventh transistor Q7, and the source of the seventh transistor Q5 is grounded. A resistor R10 is also provided between the source of the sixth transistor Q6 and the refrigeration unit, and the gate of the seventh transistor Q5 is connected to the refrigeration unit via a resistor R11.

[0053] A gate of the seventh transistor Q7 is connected to the resistor R13 , and the other end of the resistor R13 is grounded.

[0054] The TEC is controlled by transistors (Q4-Q7). This TEC typically requires high current and bidirectional control, as its operating mode (cooling or heating) depends on the direction of the current. Therefore, transistors (Q4-Q7) form an H-bridge circuit, allowing current to flow through the TEC in both directions, thereby controlling its cooling or heating function. The microprocessor (MCU) controls the transistors (Q4-Q7) via a third resistor (R8-R11) to adjust the TEC's operating state.

[0055] In this technical solution, the microprocessor controls the semiconductor transistors (Q4-Q7) through three resistors to adjust the working state of the cooling plate body TEC.

[0056] For fan modules, refer to Figure 2 It mainly includes a fan body, one end of the fan body is connected to the eighth transistor Q8, the other end of the eighth transistor Q8 is connected to the microprocessor through the resistor R14, and the other end of the fan body is connected to the cooling plate body and the semiconductor transistor.

[0057] In this technical solution, the eighth transistor Q8 is used as a switch, and the microprocessor controls the conduction through the resistor R14 to drive the fan body. It should be noted that the TEC body generates heat when working in cooling mode, so the fan body is required to dissipate heat.

[0058] The eighth transistor Q8 is further connected to a resistor R17 and a resistor R16 connected to the microprocessor. The resistor R17 is connected in parallel with a capacitor C3. One end of the resistor R17 and the capacitor C3 is connected to the resistor R16, and the other end of the resistor R17 and the capacitor C3 is grounded.

[0059] In this technical solution, resistor R17 is used for voltage division and is connected in series with the fan body and the eighth transistor Q8 to form a voltage division circuit. The RC circuit (resistor R16 and capacitor C3) is used to prevent voltage fluctuations from affecting sampling accuracy.

[0060] More specifically, one end of the fan body is connected to the drain of the eighth transistor Q8. The source of the eighth transistor Q8 is connected to a resistor R17, the other end of which is grounded. Resistor R17 is also connected in parallel with capacitor C3, meaning the other end of capacitor C3 is also grounded. One end of capacitor C3 and resistor R17 are connected to resistor R16, the other end of which is connected to the microprocessor. The gate of the eighth transistor Q8 is connected to resistors R14 and R15, respectively. The other end of resistor R15 is grounded, and the other end of resistor R14 is connected to the microprocessor.

[0061] The other end of the fan body is connected to the cooling fin body, and at the same time, the other end of the fan body is also connected to the source of the sixth transistor Q6.

[0062] In this technical solution, the fan module is controlled by transistors (Q6-Q8). The fan body typically only requires unidirectional rotation, so the eighth transistor Q8 is used as a switch. The microprocessor (MCU) controls its conduction through resistor R14, thereby driving the fan body. It is important to note that when the TEC (cooling element) is operating in cooling mode, it generates heat, requiring the fan body to dissipate the heat. In heating mode, the hot surface temperature must be maintained to provide heating. Resistor R17 is used for voltage division and is connected in series with the fan body and the eighth transistor Q8 to form a voltage divider circuit. An RC circuit (comprising resistor R16 and capacitor C3) prevents voltage fluctuations from affecting sampling accuracy.

[0063] In addition, the technical solution further includes a switch SW1 , one end of the switch SW1 is grounded, the other end of the switch SW1 is connected to the resistor R7 , and the other end of the seventh resistor is connected to the microprocessor.

[0064] In this technical solution, the switch SW1 is connected to the microprocessor via the resistor R7, and the microprocessor executes a preset program by detecting the state of the switch SW1.

[0065] In this technical solution, the microprocessor is the core of the entire control system, responsible for sending control signals to the various transistors, which in turn control the LEDs, the TEC (cooling element), and the fan. The microprocessor's MCU pins are connected to the bases of the transistors via resistors. The resistors limit current and prevent overload on the microprocessor's MCU pins. Furthermore, multiple ground (GND) symbols are included in the circuit to ensure a common reference potential for all components.

[0066] In addition, ensure that the ground connections of all components are correct to avoid ground loop problems, and the power filter capacitors are located close to the components with high power consumption, such as TEC and fans, to ensure power supply stability.

[0103] In addition, the TEC of the cooling plate and the fan require a large current, so the transistor needs a higher current carrying capacity, and MOSFET is used instead of bipolar transistors.

[0104] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
