Tire automatic inflation control device

Abstract

The invention discloses an automatic tire charging control device, which comprises a power supply, a MCU (microprocessor control unit), an LCD screen, a control panel, an illumination lamp, a backlight lamp, an electric control valve, a limit switch, a manual charge switch, a pressure sensor, a buzzer, an LED state indicator lamp, a manual exhaust valve, and an air pressure input and output interfaces. The device can be used for charging a tire respectively by using two control air paths for manual charging and automatic charging. Before the preparation for automatic charging, the charging pressure of the device is preset and the charging process can be controlled in real time, thus achieving timely detection of set pressure, discharge and accurate electronic metering for the automatic charging process, preventing the occurrence of overpressure or underpressure, and achieving pressure setting, measurement and accuracy control of the charging process to meet the charging requirement of different tires. The device may also be used for other occasions requiring accurate charging other than tires.

Description

technical field [0001] The invention belongs to the technical field of air compression equipment, and relates to an air compressor inflation device, in particular to an automatic tire inflation control device. Background technique [0002] At present, most of the tires on the market are inflated by air compressors and externally connected to the air storage tank. The inflation gun that is manually pulled by the manual trigger switch is inserted into the tire air nozzle for inflation, and the tire inflation pressure is monitored by the mechanical pressure gauge installed in the inflation device. However, real-time control of inflation overpressure, underpressure and pressure accuracy cannot be carried out. Although some can be controlled, the control accuracy is poor. This inflation method is low in efficiency and takes a long time, and it is difficult to meet various tire inflation requirements. Contents of the invention [0003] The purpose of the present invention is to ...
