Simple automobile tire automatic inflation device and inflation method

Abstract

The invention discloses a simple automobile tire automatic inflation device and an inflation method. The automatic inflation device comprises an inflation valve, a deflation valve, a low-pressure sensor which is used for sensing the pressure of an inflated object and is triggered at low pressure, a high-pressure sensor which is used for sensing the pressure of the inflated object and is triggered at high pressure, a pressure option switch for setting an inflation pressure, and a control circuit which is used for correspondingly controlling the inflation valve and the deflation valve according to the state of the pressure option switch and signals of the low-pressure sensor and the high-pressure sensor. The simple automatic inflation device has the advantages of easy manufacture, low cost, strong practicality and convenience in maintenance and use, can be recycled for a long time, and facilitates standard operation. According to the automatic inflation device and method, a mode of inflating before deflating is adopted, and a plurality of objects to be inflated can be inflated at the same time, so that mutual interference is avoided, and working efficiency is increased.

Description

technical field [0001] The invention relates to an inflation device, in particular to a simple automatic inflation device and an inflation method which can be used to inflate tires. Background technique [0002] Existing inflation devices generally include an inflation valve connected to an air source, a deflation valve connected to a vent pipe, and a pressure detection element for detecting the internal pressure of an inflated object. The inflation device with a slightly simpler structure is an inflation valve and a deflation valve respectively It is controlled by the inflation switch and the deflation switch, and the operator controls the inflation switch and the deflation switch according to the indication of the pressure detection element, and the operation is cumbersome. [0003] The automatic inflation device using program control (integrated circuit) has high inflation accuracy and inflation speed, but it cannot inflate and deflate multiple tires at the same time, and...

Problems solved by technology

[0002] Existing inflation devices generally include an inflation valve connected to an air source, a deflation valve connected to a vent pipe, and a pressure detection element for detecting the internal pressure of an inflated object. The inflation device with a slightly simpler structure is an inflation valve and a deflation valve respectively Use the inflation switch and deflation switch to control, the operator controls the inflation switch and deflation switch according to the instructions of the pressure detection element, the operation is more cumbersome

[0003] The automatic inflation device using program control (integrated circuit) has high inflation accuracy and inflation speed, but it cannot inflate and deflate multiple tires at the same time, and cannot switch manually or automatically; if the tire pressure needs to be temporarily adjusted, the existing air pressure needs to be adjusted After exhausting, re-set the inflation value for secondary inflation, which increases the labor intensity of the operator

Not only that, but the cost of the existing automatic inflation device is too high, the requirements for operators are high, and the setting and modification of the program requires more professional personnel. Once damaged, maintenance is difficult and expensive, and it is inconvenient to formulate standardized operating procedures
