The invention belongs to the field of civil oxygen generation, and particularly relates to a molecular sieve oxygen generation mechanism. Most oxygen generators sold in the market have the problems that interior structures are complex, hoses are in a mess and assembly efficiency is low. The molecular sieve oxygen generation mechanism comprises a first molecular sieve cylinder and a second molecular sieve cylinder, an upper cover is arranged on the upper side of the first molecular sieve cylinder and the second molecular sieve cylinder, and a lower cover assembly is arranged on the lower side of the first molecular sieve cylinder and the second molecular sieve cylinder; the upper cover is provided with a gas inlet joint, and gas is guided into the first molecular sieve cylinder and the second molecular sieve cylinder separately through a distribution valve. Complicated gas pipelines in an oxygen generator are reduced; connection hoses between the distribution valve and the molecular sieve cylinders and a silencer are omitted, connection hoses between the molecular sieve cylinders and a pressure stabilization cylinder are omitted, a hose for installing a washing calibration hole is omitted, and the washing calibration hole is directly inserted in the upper cover in injection molding of the lower cover as an insert.
Description
technical field [0001] The invention belongs to the field of civil oxygen production, and in particular relates to a molecular sieve oxygen production mechanism. Background technique [0002] At present, in the field of civilian oxygen production, household or medical oxygen generators are basically molecular sieve oxygen generators. The working principle is to separate oxygen and nitrogen in the air through molecular sieve pressure swing adsorption to obtain high-concentration oxygen. Most of the oxygen concentrators sold on the market have complex internal structures, messy hoses, and low assembly efficiency. Contents of the invention [0003] The technical problem to be solved by the invention is to save the intricate gas pipelines inside the oxygen generator. The connecting hose between the distribution valve and the molecular sieve cylinder and the muffler is cancelled, the connecting hose between the molecular sieve cylinder and the pressure regulator cylinder is ca...
