Embodiment Construction

[0023] Some embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 10 . It should be noted that the technical scope of the present invention is not limited by these examples.

[0024] As shown in Figures 1 to 5, an oxygen enrichment device, that is, an oxygen enrichment membrane module 35, is provided inside the oxygen enricher body 1 (hereinafter referred to as "body 1"), and the oxygen enrichment membrane module 35 is used for Oxygen-enriched air is generated by increasing the oxygen concentration in the air sucked into the living body 1 by an inhalation device 26 described later. After the air passes through the oxygen-enriched membrane module 35, the oxygen concentration in the air increases by about 30% (about 70% of nitrogen) from the normal concentration of 21% (about 79% of nitrogen) before passing through.

[0025] In addition, an air suction device 26 is also provided inside the body 1, and the air suction device 26 sucks...

Abstract

The invention provides an oxygen enricher with low vibration and low noise, which comprises a vacuum pump (5) connected at the upstream side of an oxygen enriching film component (35) to absorb the air around the oxygen enriching film component into the oxygen enriching film component, an air supply mouth (6) enabling the oxygen enriching air to be exhausted out, and a plurality of spring parts (31, 32) arranged between the vacuum pump and a machine shell (42) near the side of a piston and far away from the side of the piston in the vacuum pump and used to support the vacuum pump. The spring constant of the spring part (32) arranged on the side of the piston of the vacuum pump is set to be different from that of the spring part (31) at the side opposite to the piston; for instance, the spring part with bigger spring constant is arranged on the side with large vibration amplitude while the spring part with smaller spring constant is arranged on the side with less vibration amplitude, so that the vibration can be effectively eased and the noise also can be reduced.

Description

technical field [0001] The invention relates to an oxygen enricher which uses an oxygen enrichment device composed of an oxygen enrichment membrane module to obtain oxygen-enriched air and then provides the oxygen-enriched air to users. Background technique [0002] This existing oxygen enricher is provided with: an oxygen enrichment membrane module that condenses the oxygen in the air to generate oxygen-enriched air; a vacuum pump connected to the downstream side of the oxygen enrichment membrane module; and a vacuum pump connected to the On the downstream side of the vacuum pump, the oxygen supply port for exhausting oxygen-enriched air. When in use, the oxygen supply port is arranged near the user's mouth, and then the vacuum pump is made to work. When the vacuum pump is working, the air around the oxygen-enriched membrane module is sucked through the oxygen-enriched membrane module to obtain oxygen-enriched air; after such oxygen-enriched air is discharged from the oxyg...
