A control reversing device for the gas circuit of an oxygen concentrator

Abstract

The invention discloses a control reversing device of gas circuits of an oxygen concentrator. The control reversing device comprises an upper cover plate, a valve body and a lower cover plate, wherein a left cavity and a right cavity are formed inside the valve body, supporting frames, linkage assemblies, upper end cover sealing assemblies and lower end cover sealing assemblies are arranged in the left cavity and the right cavity of the valve body respectively, the upper cover plate and the lower cover plate are installed on the valve body through screws, a valve body gas circuit is arranged inside the valve body, the upper cover plate and the lower cover plate are respectively provided with a cover plate gas circuit, a passage is formed by the cover plate gas circuit on the upper cover plate, the cover plate gas circuit on the lower cover plate and the valve body gas circuit on the valve body, a solenoid valve is further arranged on the valve body, and a plurality of pipe connectors which are communicated with the valve body gas circuit are further arranged on the valve body. According to the control reversing device of the gas circuits of the oxygen concentrator, control over the two gas circuits can be achieved only through connection and disconnection of one solenoid valve, the sealing mode is simple, working is flexible, working efficiency is greatly improved, the production cost is reduced, high economic benefit and high social benefit are achieved, and the good foundation is laid for mass production in the future.

Description

technical field [0001] The invention belongs to the technical field of oxygen concentrators, and relates to a control and reversing device for the gas circuit of the oxygen concentrator, which is mainly used for medical equipment oxygen concentrators, household oxygen concentrators and other pneumatic equipment requiring gas circuit reversing. Background technique [0002] With the rapid development of the economy and the continuous improvement of human consciousness, people tend to pursue a healthy lifestyle, and the demand for quality of life is also getting higher and higher. Moreover, due to the pollution of the earth's environment, eating habits, closed home office space, lack of exercise, age and many other factors, which in turn lead to the occurrence of various diseases, modern people have to pay attention to oxygen supplementation in normal times. With the continuous development of medical device technology, many medical devices that were previously only used in med...
