It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0058] Figure 1 A schematic diagram of the power regulation circuit provided in a preferred embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0059] The power regulation circuit described above includes an induction circuit 10, a control circuit 20, and a conversion circuit 30.

[0060] The sensing circuit 10 is used to output a sensing signal according to the touch operation and an adjustment signal according to the sliding operation.

[0061] The control circuit 20 is connected to the sensing circuit 10 and is used to wake up in response to the sensing signal, and output a control signal according to the adjustment signal after waking up.

[0062] The conversion circuit 30 is connected to the control circuit 20 and is used to receive the input DC power and convert the input DC power into the output DC power according to the control signal.

[0063] Both touch and swipe operations are performed on the same component.

[0064] It is understandable that the control signal can be a pulse width modulation (PWM) signal, and the duty cycle of the PWM signal is related to the adjustment signal.

[0065] like Figure 2 As shown, the sensing circuit 10 includes a voltage divider resistor assembly 11, a sliding potentiometer RT1, and a touch detection module 12.

[0066] The voltage divider resistor assembly 11 and the sliding potentiometer RT1 are used to output an adjustment signal according to the sliding operation.

[0067] The sliding potentiometer RT1 is connected to the voltage divider resistor assembly 11 and is also used to sense the contact between its own adjustment terminal and the human body to output a contact signal.

[0068] The touch detection module 12 is connected to the housing of the sliding potentiometer RT1 and is used to output a sensing signal in response to a touch signal.

[0069] The outer shell and the adjustment terminal of the sliding potentiometer RT1 are both metal and in contact with each other.

[0070] Through the above technical solution, the sliding potentiometer RT1 senses the contact between its adjustment terminal and the human body to output a contact signal; thus, the sliding potentiometer RT1 can simultaneously serve as a resistance adjustment device and a touch contact device, simplifying the hardware design and saving costs. Furthermore, since both the outer shell and the adjustment terminal of the sliding potentiometer RT1 are metal and in contact with each other, the human body can simultaneously complete touch and sliding operations by contacting and sliding the adjustment terminal of the sliding potentiometer RT1, improving the convenience of use.

[0071] like Figure 3 As shown, the power regulation circuit also includes a pressure sensing circuit 40.

[0072] The air pressure sensing circuit 40 is connected to the control circuit 20 and is used to output a trigger signal in response to the air pressure being less than a preset value.

[0073] The control circuit 20 is connected to the sensing circuit 10 and is used to wake up in response to the sensing signal, and after waking up, it responds to the trigger signal and outputs a control signal according to the adjustment signal.

[0074] like Figure 4 As shown, the power regulation circuit described above also includes a current limiting circuit 50.

[0075] The current limiting circuit 50 is connected to the control circuit 20 and is used to limit the output DC current.

[0076] The control circuit 20 is connected to the sensing circuit 10 and is used to wake up in response to the sensing signal, and after waking up, it outputs a control signal according to the adjustment signal and the current-limited output DC power.

[0077] By limiting the output DC power before inputting it to the control circuit 20, the reliability of the power regulation circuit is improved.

[0078] Figure 5 The diagram illustrates a partial example circuit structure of a power regulation circuit provided in an embodiment of the present invention. For ease of explanation, only the parts relevant to the embodiment of the present invention are shown, and are described in detail below:

[0079] The voltage divider resistor assembly 11 includes a first resistor R1.

[0080] The first end of the first resistor R1 is connected to the first power supply VAA; the second end of the first resistor R1, the adjustment terminal 1 of the sliding potentiometer RT1, and the first end 2 of the sliding potentiometer RT1 are connected together and serve as the adjustment signal output terminal of the sensing circuit 10, which is connected to the control circuit 20 to output the adjustment signal; the second end 3 of the sliding potentiometer RT1 is connected to the power supply ground; the outer shell G of the sliding potentiometer RT1 serves as the contact signal output terminal of the sliding potentiometer RT1, which is connected to the touch detection module 12 to output the contact signal.

[0081] It is understandable that the first resistor R1 and the sliding potentiometer RT1 are connected in series. The resistance of the sliding potentiometer RT1 can be adjusted by sliding, thereby outputting a variable adjustment signal.

[0082] It should be noted that the sensing circuit 10 may also include a fifth capacitor C5, the first end of which is connected to the second end of the first resistor R1, the adjustment terminal 1 of the sliding potentiometer RT1, and the first terminal 2 of the sliding potentiometer RT1.

[0083] The touch detection module 12 includes a touch detection chip U1, a first capacitor C1, a second capacitor C2, a first resistor R1, and a second resistor R2.

[0084] The first end of the first resistor R1 forms the input terminal of the touch detection module 12 and is connected to the sliding potentiometer RT1 to input a touch signal; the second end of the first resistor R1 is connected to the sensor input terminal I of the touch detection chip U1 and the first end of the first capacitor C1; the first end of the second resistor R2 is connected to the second power supply VBB; the power supply terminal VDD of the touch detection chip U1 is connected to the second end of the second resistor R2 and the first end of the second capacitor C2; the ground terminal VSS of the touch detection chip U1, the second end of the first capacitor C1, and the second end of the second capacitor C2 are all connected to the power supply ground; the CMOS output terminal Q of the touch detection chip U1 forms the output terminal of the touch detection module 12 and is connected to the control circuit 20 to output a sensing signal.

[0085] The air pressure sensing circuit 40 includes an air pressure sensor U2, a third capacitor C3, and a third resistor R3.

[0086] The first end of the third resistor R3 is connected to the third power supply VCC. The power supply terminal VDD of the pressure sensor U2 is connected to the second end of the third resistor R3 and the first end of the third capacitor C3. The second end of the third capacitor C3 and the ground terminal GND of the pressure sensor U2 are connected to the power supply ground. The output terminal GATE of the pressure sensor U2 constitutes the output terminal of the pressure sensing circuit 40 and is connected to the control circuit 20 to output a trigger signal.

[0087] The control circuit 20 includes a microprocessor U3 and a fourth capacitor C4.

[0088] The first general-purpose input / output terminal PA4 of the microprocessor U3 constitutes the sensing signal input terminal of the control circuit 20 and is connected to the sensing circuit 10 to receive the sensing signal; the second general-purpose input / output terminal PA2 of the microprocessor U3 and the first end of the fourth capacitor C4 are connected and together constitute the adjustment signal input terminal of the control circuit 20 and are connected to the sensing circuit 10 to receive the adjustment signal; the second end of the fourth capacitor C4 is connected to the power supply ground; the third general-purpose input / output terminal PA3 of the microprocessor U3 constitutes the trigger signal input terminal of the control circuit 20 and is connected to the air pressure sensing circuit 40 to receive the trigger signal; the fourth general-purpose input / output terminal PA11 of the microprocessor U3 constitutes the DC power input terminal of the control circuit 20 and is connected to the current limiting circuit 50 to receive the current-limited output DC power; the fifth general-purpose input / output terminal PB0 of the microprocessor U3 constitutes the control signal input terminal of the control circuit 20 and is connected to the conversion circuit 30 to output the control signal.

[0089] The conversion circuit 30 includes a first field-effect transistor M1, a fourth resistor R4, and a fifth resistor R5.

[0090] The source of the first field-effect transistor M1 and the first end of the fourth resistor R4 are connected and together form the input terminal of the conversion circuit 30 to receive input DC power; the gate of the first field-effect transistor M1 is connected to the second end of the fourth resistor R4 and the first end of the fifth resistor R5; the drain of the first field-effect transistor M1 forms the output terminal of the conversion circuit 30 to output DC power; the second end of the fifth resistor R5 forms the control terminal of the conversion circuit 30 and is connected to the control circuit 20 to receive control signals.

[0091] In one embodiment, the output DC power is used to power the load RL.

[0092] The control signal mentioned above can be a PWM signal. The microprocessor U3 adjusts the duty cycle of the PWM signal according to the adjustment signal, so that the voltage of the output DC power changes with the adjustment signal, thereby achieving the purpose of adjusting the output power.

[0093] The following is based on the working principle. Figure 5 Further explanation is provided below:

[0094] When a human touches and slides the adjustment terminal of the sliding potentiometer RT1, the second terminal of the first resistor R1, the adjustment terminal 1 of the sliding potentiometer RT1, and the first terminal 2 of the sliding potentiometer RT1 jointly output an adjustment signal to the second general-purpose input / output terminal PA2 of the microprocessor U3. Since the casing of the sliding potentiometer RT1 and its adjustment terminal are both metal and in contact, the casing G of the sliding potentiometer RT1 outputs a contact signal to the sensor input terminal I of the touch detection chip U1. Based on the contact signal, the touch detection chip U1 outputs a sensing signal from its complementary metal-oxide-semiconductor (CMOS) output terminal Q to the first general-purpose input / output terminal PA4 of the microprocessor U3. In response to the air pressure being lower than a preset value, the barometric pressure sensor U2 outputs a trigger signal from its output terminal GATE to the third general-purpose input / output terminal PA3 of the microprocessor U3.

[0095] The microprocessor U3 is woken up by a sensing signal and, after being woken up, responds to a trigger signal. According to the adjustment signal, it outputs a control signal from the fifth general-purpose input / output terminal PB0 of the microprocessor U3 to the gate of the first field-effect transistor M1. The control signal can be a PWM signal, and the duty cycle of the PWM signal is related to the adjustment signal. The first field-effect transistor M1 converts the input DC power into the output DC power to supply power to the load RL according to the control signal. The output DC power is current-limited by the sixth resistor R6 and then input to the fourth general-purpose input / output terminal PA11 of the microprocessor U3 as feedback, so that the microprocessor U3 adjusts the voltage of the output DC power according to the feedback. Thus, while realizing power regulation, power consumption is reduced, energy is saved, and the ease of use of the power regulation circuit is improved.
