Mute type oxygen generator

Abstract

The invention discloses a mute type oxygen generator. The mute type oxygen generator comprises an exhaust pipe, wherein the exhaust pipe is connected to a noise reduction device which divides the exhaust process into continuous single exhaust and performs pressure reduction to reduce noise; an outer mute shell is arranged on the noise reduction device; and an air outlet is formed in one end of theouter mute shell. According to the mute type oxygen generator, the noise reduction device is arranged at the end of the exhaust pipe of a compressor, and continuously divides high-pressure air into independent small-flow air through continuous connection of kidney-shaped holes in a first air distribution pipe and air passing holes in a second air distribution pipe, and the air is compressed alongwith a first spring, so that the pressure intensity is reduced, the exhaust speed is reduced, and the noise is reduced; a sliding block cannot reset in the exhaust process due to the existence of a driving mechanism; the gas in a cavity is effectively exhausted and then the sliding block resets; and the noise is reduced through a sound absorption material, the kinetic energy of the impacted gas is reduced, the exhaust speed is reduced, and therefore the generated noise is reduced.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a silent oxygen generator. Background technique [0002] The oxygen generator uses molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and becomes high-purity after purification. oxygen. The molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can absorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve does not consume. [0003] Because the compressor of the oxygen concentrator needs to discharge other gases such as nitrogen after extracting oxygen, there is an exhaust port, but because the gas is in a high-pressure state after being compressed, it will generate a lot...

AI Technical Summary

Problems solved by technology

[0003] Because the compressor of the oxygen concentrator needs to discharge nitrogen and other gases after extracting oxygen, there will be an exhaust port, but because the gas is in a high-pressure state after being compressed, it will generate a lot of noise when it is discharged, so The oxygen generator makes a lot of noise when the compressor exhausts
