[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution: an air pressure lamp control circuit, including a detection handle, an air pressure sensor arranged in the detection handle, a processing circuit, a docking port arranged outside the detection handle, a lighting lamp and a display. The docking port is connected to the detection end of the air pressure sensor through an air pipe,

[0020] The processing circuit includes a processor, a control switch, a power supply, and a power supply manager,

[0021] The air pressure sensor, the display and the control switch are respectively connected to the I / O ports of the processor. The power supply is connected to the power supply manager, and the output ends of the power supply manager are respectively connected to supply power to the air pressure sensor, the processor, the lighting lamp and the display.

[0022] The lighting lamp is a ring-shaped aperture lamp, and the lighting lamp is sleeved and arranged outside the docking port.

[0023] The ring-shaped setting improves the lighting effect and facilitates the matching of the docking port with the air nozzle.

[0024] The processor is a STG-CS35 type processor.

[0025] The power manager is a TP4056 type battery manager.

[0026] The control switch includes a power switch and a lighting switch, and the power switch and the lighting switch are respectively connected to the I / O ports of the processor.

[0027] A triode is provided at the power supply end of the lighting lamp. The positive electrode of the lighting lamp is connected to the VDD power supply port of the processor, the negative electrode of the lighting lamp is connected to the collector of the triode, the emitter of the triode is grounded, and the base of the triode is connected to the I / O port of the processor.

[0028] The display is an LED digital display.

[0029] Through this technical solution, by pressing the power switch, the processor receives the switch signal and outputs power control, enabling the pressure sensor to operate. After the docking port is aligned with the air nozzle, the air pressure in the tire is input into the pressure sensor through the air pipe. The pressure sensor can input the detected air pressure signal into the processor, and the processor converts this signal into a display signal for display on the display screen, facilitating the user to directly read the air pressure data.

[0030] In a dim environment, by turning on the lighting switch, the processor receives the lighting switch signal and outputs power control to turn on the lighting lamp, facilitating the user to detect the wheel air pressure in a dim environment.
