Household oxygen-nitrogen separation and utilization system

Abstract

The invention discloses a household oxygen-nitrogen separation and utilization system, which consists of a molecular sieve oxygenerator, a controller and an oxygen concentration sensor. The indoor isequipped with a bedroom and a kitchen, the bedroom is internally equipped with a bed, and the oxygen concentration sensor is installed in the bedroom, and is close to the bed. The oxygen concentrationsensor and the molecular sieve oxygenerator are in electric connection with the controller respectively. One side or two sides of the bed head are respectively provided with an oxygen outlet nozzle that is connected to an oxygen outlet of the molecular sieve oxygenator. The kitchen is internally equipped with a nitrogen storage tank, a nitrogen outlet of the molecular sieve oxygenator is connected to a gas inlet of the nitrogen storage tank, a one-way valve is connected between the molecular sieve oxygenator and the nitrogen storage tank, and a gas outlet of the nitrogen storage tank is connected to a first control valve and a nitrogen filling head successively. The household oxygen-nitrogen separation and utilization system provided by the invention not only can automatically adjust theoxygen concentration in the bedroom, and improve people's sleep quality, but also can collect and store the nitrogen discharged by the molecular sieve oxygenerator for people to use in daily life, thereby facilitating people's life and improving people's quality of life.

Description

technical field [0001] The invention belongs to the technical field of household oxygen and nitrogen separation and utilization, and relates to a household oxygen and nitrogen separation and utilization system. Background technique [0002] In winter, the weather in northern my country is very cold. In order to keep warm, people seldom open windows for ventilation, and even do not open windows for ventilation throughout the winter. Harmful gases such as carbon dioxide and sulfur dioxide in the room gradually increase, and the oxygen concentration gradually decreases; in summer, the weather in southern my country is very cold. In hot weather, air conditioners are generally used to adjust the indoor temperature to improve the comfort of the human body. In order to keep cold, people rarely open windows to ventilate, resulting in a decrease in indoor oxygen concentration. Sleeping in an indoor environment with low oxygen concentration will often affect people's sleep quality, res...

Problems solved by technology

The nitrogen needed for nitrogen-filling to keep fresh and make nitrogen coffee is generally provided by purchased canned nitrogen. It is very inconvenient to buy canned nitrogen for long-term use, and the cost is relatively high.
