Portable oxygen supply respirator

Abstract

The invention discloses a portable oxygen supply respirator, belonging to the technical field of molecular sieve pressure swing adsorption oxygen production. The portable oxygen supply respirator comprises a first air pressurization cabin, a second air pressurization cabin, a compressed air buffer tank, a first adsorption cabin, a second adsorption cabin and an oxygen buffer cabin, wherein the first adsorption cabin and the second adsorption cabin are respectively provided with an oxygen production molecular sieve; the compressed air buffer tank separately communicates with the two adsorptioncabins through adsorption air paths; the two adsorption cabins respectively communicate with the oxygen buffer cabin through flushing air circuits, respectively communicate with the oxygen buffer cabin through exhaust air circuits, and are respectively provided with a desorption air circuit; each air circuit is connected with a rotary air circuit time delay switch through an interface; and the first air pressurization cabin and the second air pressurization cabin respectively communicate with the compressed air buffer tank through pipelines. According to the portable oxygen supply respirator,power can be provided through multiple modes such as a motor and a rocker arm for preparation of oxygen.

Description

technical field [0001] The invention relates to a technology in the field of molecular sieve pressure swing adsorption oxygen production, in particular to a portable oxygen respirator. Background technique [0002] In an environment with thin air and hypoxia, normal human activities will be greatly restricted. For high-altitude mobile workers and some patients with breathing disorders, timely and sufficient oxygen supply equipment is particularly important for them. . [0003] At present, the oxygen production principles of commonly used oxygen production equipment include cryogenic method, membrane separation method and pressure swing adsorption method. Based on the fact that the main components in the air are oxygen and nitrogen, the cryogenic separation method uses air as a raw material, compresses, purifies, and exchanges heat to make liquefied air. Utilizing the different boiling points of liquid oxygen and liquid nitrogen in liquefied air, through rectification Obtai...
