Embodiment Construction

[0034] Hereinafter, a preferred embodiment of the present invention will be described by taking a portable oxygen concentrator as an example with reference to the accompanying drawings. Here, the present invention can be variously modified and changed, and specific examples thereof are illustrated and described in detail below. However, the present invention is not limited thereto, and various configurations are of course possible within the scope specified in the claims.

[0035] Below, refer to Figure 1A ~ 1C A brief description will be given of pressure swing adsorption (PSA) based only on compressed air and vacuum pressure swing adsorption (VPSA) based on compressed air and decompressed air. exist Figure 1A In the process, raw air obtained by introducing external air and compressed by the compressor 1 is introduced into the first adsorption cylinder 108a through a three-way switching valve 109a. Catalyst zeolite is built in the first adsorption cylinder 108a, and nitro...

Abstract

The purpose of the invention is to realize a compressor which is drastically reduced in size, weight, noise, and vibration at the same time, and an oxygen concentrator using the compressor. A compressor is provided with a set of a first piston, a first eccentric cam, and a first cylinder chamber, a set of a second piston, a second eccentric cam, and a second cylinder chamber, a set of a third piston, a third eccentric cam, and a third cylinder chamber, and a set of a fourth piston, a fourth eccentric cam, and a fourth cylinder chamber. A first center axis common to the first piston and the second piston and a second center axis common to the third piston and the fourth piston are arranged perpendicular to each other.

Description

technical field [0001] The present invention relates to a compressor and an oxygen concentrator using the compressor, in particular to a medical portable oxygen concentrator based on pressure swing adsorption. Background technique [0002] An oxygen concentrator based on a pressure swing adsorption method has been put into practical use for medical use. The oxygen concentrator uses zeolite as an adsorbent that selectively absorbs nitrogen through oxygen in the air to generate oxygen. [0003] According to the oxygen concentrator of this aspect, the raw air taken in from the air inlet is compressed using a compressor as the compression mechanism to generate compressed air, and the compressed air is supplied to the adsorption cartridge containing the adsorbent to generate oxygen. . In addition, the generated oxygen is stored in the tank, and a predetermined flow rate of oxygen can be supplied from the tank through the pressure reducing valve and the flow rate regulator, there...
