Portable molecular sieve oxygen generator

Abstract

The invention discloses a portable molecular sieve oxygen generator. The portable molecular sieve oxygen generator comprises an oxygen generator shell and is characterized in that a frame is mounted on the left side of the oxygen generator shell, a miniature gear motor is connected to the left side of the rear end of the frame in a bolt connection manner, the output end of the miniature gear motoris provided with a reciprocating moving mechanism in a frame penetrating manner, an oxygen outlet is connected to the left side of the bottom end of the oxygen generator shell in a threaded manner, amolecular sieve is mounted at the center of the oxygen generator shell, a first one-way valve is mounted at the top end of the inner wall of the oxygen generator shell, and a second one-way valve ismounted at the bottom end of the inner wall of the oxygen generator shell. The portable molecular sieve oxygen generator has the advantages that by structures such as the oxygen generator shell, the second one-way vale, a gas inlet and the oxygen outlet, pressure intensity in the generator is increased to allow the air to sufficiently contact with the molecular sieve, and reaction speed is increased; by structures such as a handle, a pull rod and a pull lever, oxygen flow speed can be regulated according to different use people, evident beneficial effects are achieved, and high adaptability isachieved.

[0002] Oxygen concentrator is a kind of machine for producing oxygen. According to the principle of oxygen production, the characteristics of each oxygen concentrator are different. The oxygen production principle of oxygen concentrator includes the principle of molecular sieve, the principle of polymer oxygen-enriched membrane, the principle of electrolyzed water Principle and principle of chemical reaction oxygen production. Molecular sieve oxygen generator refers to equipment that extracts oxygen from the air based on pressure swing adsorption technology. It uses molecular sieve physical adsorption and desorption technology to fill molecular sieves in the oxygen generator. When absorbing nitrogen in the air, the remaining unabsorbed oxygen is collected, and high-purity oxygen can be obtained after purification. In the molecular sieve tower of the oxygen generator, a porous equalizer is usually set at the bottom of the molecular sieve. As a result, the air entering the molecular sieve tower can evenly flow through the molecular sieve, which improves the use efficiency of the molecular sieve. However, the existing oxygen generators in the market have different oxygen requirements during oxygen therapy according to different users. , the existing oxygen generator is inconvenient to adjust the oxygen flow rate when in use, and there is no gap pressurization device in the prior art, which cannot make the air fully contact with the molecular sieve, which reduces the work efficiency, affects the product qualification rate, and increases the work time, the beneficial effect is not obvious
