Inflatable and vacuum all-in-one machine for automobile

Abstract

The present invention is an automobile inflatable and dust-absorbing integrated machine, comprising a base and a housing arranged on the base, an air pump, a dust-absorbing device and a controller are arranged in the housing, and the controller includes a The work switch on the cover, the output pressure controller, and the safety protector; wherein the output pressure controller includes a single-chip microcomputer, a signal input unit connected with the single-chip microcomputer, a temperature compensation circuit unit and a signal output unit, and is installed on the air pump and The air pressure display connected with the single-chip electromechanical, the temperature sensing unit detects and collects the temperature of the working environment of the air pump, and transmits the collected temperature information to the temperature compensation circuit unit and the single-chip microcomputer. It adopts digital temperature compensation and self-adaptation in a large temperature range. Control or fuzzy control algorithm with temperature as a parameter to calculate the air pressure value under the current working environment temperature conditions, and display the calculated air pressure value on the air pressure display screen.

Description

technical field [0001] The invention relates to an automobile inflating and vacuuming integrated machine. Background technique [0002] The current car washing equipment and inflatable equipment are generally two sets of equipment. The car washing equipment only has the function of car washing, and the inflatable equipment only has the function of inflating, which takes up more space on the car and is not convenient to use. [0003] With the continuous improvement of people's economic level, cars have entered thousands of households, and at the same time, air pumps are also produced. The air pump is used to automatically inflate the tires and can control the inflation pressure so that the car tires can get a suitable pressure value. Air pumps are generally analog barometer air pumps and ordinary digital control display air pumps. But there is a problem: the current analog barometer air pump and the digital barometer of the ordinary digital control display air pump have zero...

AI Technical Summary

Problems solved by technology

But there is a problem: the current analog barometer air pump and the digital barometer of the ordinary digital control display air pump have zero temperature drift and air pressure measurement temperature drift, which makes the air pressure display in special extreme weather conditions such as extreme low temperature or high temperature. Inaccurate, causing the car tires to not get the proper pressure value

[0004] In addition, the frequency of use of the device is not very high, so the lithium battery built in the casing is not used frequently, the utilization rate is low, and the function is single, and when the lithium battery is damaged, the entire device cannot be used, and the entire device needs to be replaced, that is, Increased use cost; the device is driven by a connecting wire passing through the housing and connected to the car cigarette lighter, so because the length of the connecting wire is limited, sometimes the device cannot reach every corner of the car, which gives It is inconvenient to use and place the inflatable vacuum dual-purpose machine
