Flow-adjustable continuous and pulsed dual-mode oxygen supply module

Abstract

The invention discloses a flow-adjustable continuous and pulsed dual-mode oxygen supply module. The module comprises a flow adjusting unit, an air inlet unit, an air outlet unit and an air suction unit. The flow adjusting unit comprises a valve body and a check ring, the valve body synchronously rotates around a valve rod, a plurality of throttling holes and a bypass hole are formed in the valve body, a first air channel corresponding to the throttling holes is formed in a decompression chamber cover plate, and the first air channel and a second air channel communicate with an air inlet sourcethrough the throttling holes and the bypass hole respectively. The air outlet unit comprises an air outlet outer joint, an air outlet valve plate and an air outlet cavity which are arranged on the valve body. The air suction unit comprises an air suction outer joint, an air suction valve plate and an air suction cavity which are arranged on a valve cover, an air inlet convex nozzle communicatingwith the air outlet cavity is arranged on the air suction valve plate, and an air inlet diaphragm used for opening and closing the air inlet convex nozzle is arranged above the air inlet convex nozzle. According to the module, pure mechanical parts are adopted to realize oxygen supply in pulsed and the continuous modes, the flow is adjustable, power supply is not needed in use, and requirements ofspecial occasions are met.

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 a continuous and pulse dual-mode oxygen supply module with adjustable continuous flow. 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 ...

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
