Airtight detection device controlled by single chip microcomputer

Abstract

The invention discloses an airtight detection device controlled by a single chip microcomputer. The airtight detection device comprises a console; a test box is placed at the top of the console; a chamber is arranged on the test box; a single chip microcomputer controller is fixedly installed on the inner wall of one side of the chamber; a display screen is fixedly arranged on the inner wall of the top of the chamber; a booster pump is fixedly installed on the inner wall of one side of the chamber; the booster pump and the display screen are both electrically connected with the single chip microcomputer controller; the bottom of the booster pump is hermetically provided with an air inlet pipe; and a protection box is fixedly arranged on the inner wall of the bottom of the chamber. The airtight detection device controlled by the single chip microcomputer provided by the invention is simple in structure and convenient to operate; the airtight condition of the device body can be known bysetting a comparison device, and an air pressure sensor is not needed, thus the investment cost is reduced; an air leakage part can be found by setting a thin film, and a worker is not required to find the air leakage part little by little, thereby reducing the working intensity of the worker and improving the efficiency of detecting the air leakage part.

Description

technical field [0001] The invention relates to the technical field of air tightness detection, in particular to an air tightness detection device controlled by a single-chip microcomputer. Background technique [0002] At present, it is often necessary to detect the airtightness of products in industrial production. The application announcement number is CN108332920A.

Problems solved by technology

[0003] This invention uses the air pressure sensor to sense the air pressure, which increases the input cost, and requires manpower to find the leaking parts bit by bit, which is not efficient. Therefore, we propose a single-chip microcomputer-controlled air-tight detection device to solve the above-mentioned problems. question
