Problems solved by technology

[0002] The biggest problem with existing household oxygen concentrators is that the oxygen concentration provided is not constant, which affects the user experience and fails to meet the expected health care or treatment requirements. The reason is the lack of a feedback control mechanism , In addition, the existing oxygen generator lacks an output filter device, which is easy to bring impurities into the user's body and cause unnecessary damage to the user

Abstract

The invention discloses a control method of a household oxygen generator. The control method comprises the following control steps: (1) controlling N adsorption towers to work alternately through a time-sharing control mechanism; wherein N> = 3; and (2) controlling the valve opening degree of an electric control switching valve through oxygen content detection, and controlling the content of output oxygen to be constant; and (3) realizing the temperature of the output oxygen by controlling the water temperature in the water bath filter. The control method of the household oxygen generator is easy to implement and simple and convenient to control.

Description

technical field [0001] The invention relates to a control method of a household oxygen generator. Background technique [0002] The biggest problem with existing household oxygen concentrators is that the oxygen concentration provided is not constant, which affects the user experience and fails to meet the expected health care or treatment requirements. The reason is the lack of a feedback control mechanism , In addition, the existing oxygen concentrator lacks an output filter device, which is easy to bring impurities into the user's body and cause unnecessary damage to the user. Therefore, it is necessary to design a new control method for household oxygen generators. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control method for a household oxygen generator, which is easy to implement and simple to control. [0004] The technical solution of the invention is as follows: [0005] A control method for a ...
