Self-adaptive control oxygen supply module

Abstract

The invention discloses a self-adaptive control oxygen supply module which comprises a gas inlet unit, a gas outlet unit and an inspiration unit. The gas inlet unit comprises a first gas channel and asecond channel, wherein gas from the same gas inlet source enters the first gas channel and the second gas channel. The gas outlet unit comprises a gas outlet external joint arranged on a valve body,a gas outlet valve plate and a gas outlet cavity. The inspiration unit comprises an inspiration external joint arranged on a cover, an inspiration valve plate and an inspiration cavity. A gas inlet convex nozzle communicating with the gas outlet cavity is arranged on the inspiration valve plate. A gas inlet membrane used for opening and closing the gas inlet convex nozzle is arranged above the gas inlet convex nozzle. The gas inlet membrane is located in the gas inlet cavity, an adjusting elastic element is arranged above the gas inlet membrane, and the gas inlet cavity communicates with theinspiration external joint through a gas path. By means of the self-adaptive control oxygen supply module, pure mechanical parts are adopted to achieve oxygen supply of a pulse mode and a continuous mode, a inspiration channel and a breathing channel can be opened self-adaptively according to the breathing actions of users in the pulse manner to achieve pulse oxygen uptake, and the aim of saving the oxygen quantity is achieved.

Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing, and relates to an automatic gas control valve, in particular to an adaptively controlled oxygen supply module. Background technique [0002] In the production of plateau oxygen supply, underwater oxygen supply and oxygen supply equipment for people with dyspnea in hospitals, oxygen tanks are often used to supply oxygen to users through gas control valves. During use, high-pressure oxygen needs to be filled into the gas tanks first, and then Oxygen is delivered to the user from the tank. Existing gas cylinders have a complicated oxygen supply structure, including independent decompression, flow adjustment and output modules, and there are many conduits and lead wires. The output oxygen flow rate of the oxygen supply equipment in the process of exhaling and exhaling is all constant, only when people inhale, oxygen can be effectively used, and when exhaling, the oxygen is all discha...

AI Technical Summary

Problems solved by technology

In use, the breathing valve has poor sensitivity to the air outlet of the human body. The user will only supply oxygen in pulses when he is in a state of exercise or inhaling hard. When the human body is in a static state, sleeping state or the valve body is in a horizontal position, it often occurs that there is no air. Or the failure of pulse output, which limits its popularization and application in many occasions
