Problems solved by technology

At present, most domestic oxygen generators adopt the molecular sieve pulse oxygen generation technology. Its working principle is to separate the oxygen and nitrogen in the air through the molecular sieve pressure swing adsorption method to obtain high-concentration oxygen. However, the internal structure of the molecular sieve oxygen generation mechanism of the existing oxygen generator is complicated , Messy trachea, poor reliability, low assembly efficiency, large structure and heavy weight

Abstract

The invention discloses a molecular sieve oxygen generation mechanism of a portable oxygen generator. The molecular sieve oxygen generation mechanism comprises an oxygen storage tank (1), a right molecular sieve tank (24), a left molecular sieve tank (25), an electromagnetic valve seat (5) and a lower gas path cover (34), the interior of the oxygen storage tank (1) is divided into a left cavity, amiddle cavity and a right cavity, the left molecular sieve tank (25) is placed in the left cavity, and the right molecular sieve tank (24) is placed in the right cavity; a plurality of air paths arearranged on the electromagnetic valve seat (5) and the lower air path cover (34) to perform pressurized adsorption and decompressed desorption blow-off on the right molecular sieve tank (24) and the left molecular sieve tank (25), so that the product quality of the molecular sieve oxygen generation mechanism of the portable oxygen generator is improved.

Description

technical field [0001] The invention belongs to the field of mechanical structures, and in particular relates to a molecular sieve oxygen generating mechanism of a portable oxygen generator. Background technique [0002] The small and light portable oxygen concentrator provides a guarantee for the oxygen inhalation needs of people who work and travel in the outdoor environment on the plateau. A molecular sieve oxygen generator with excellent structural design and high reliability is the basis to ensure that the portable oxygen generator is portable, efficient, safe and reliable. At present, most domestic oxygen generators adopt the molecular sieve pulse oxygen generation technology. Its working principle is to separate the oxygen and nitrogen in the air through the molecular sieve pressure swing adsorption method to obtain high-concentration oxygen. However, the internal structure of the molecular sieve oxygen generation mechanism of the existing oxygen generator is complica...
