Description

Oxygen generator for respiration

The utility model relates to a device for providing oxygen for breathing for people, in particular to a breathing oxygen generator for providing continuous oxygen for some indoor people with oxygen deficiency.

At present, most of the time in normal life of people is spent indoors. Such as: living rooms, office rooms, driver's cabins and ward rooms, and event rooms in some public places, etc. Because various sources often cause the indoor air to be polluted and lack oxygen, and influence the health of people, people often use methods such as ventilation and the like to improve the oxygen content of the indoor air, and the methods usually have higher noise and certain influence on the indoor temperature. Also, steel bottled liquid oxygen has been used to increase the oxygen content of air indoors by diffuse release, which has the disadvantages of large volume, high cost and insecurity.

The utility model aims at providing a breathing oxygen generator which can continuously provide breathing oxygen for people.

The purpose of the utility model is realized like this: because water is composed of two elements, hydrogen and oxygen, if water is electrolyzed, hydrogen and oxygen are generated, and the chemical equation is as follows: the utility model is designed by utilizing the property of water. The machine shell formed by injection molding is divided into an upper part and a lower part, the lower part is provided with an electrolytic tank, a gas isolating pole is arranged in the middle of the electrolytic tank, the electrolytic tank is divided into two parts, and the lower end of the gas isolating pole is provided with a gap with the bottom of the electrolytic tank so as to communicate the bottoms of the electrolytic tanks of the two parts. Two groups of electrode plates are respectively arranged in the two parts of electrolytic tanks, one is a positive electrode plate, the other is a negative electrode plate, and two groups of electrodesThe bottom edge of the plate is higher than the lower end of the gas separation plate. The side surface of the two-part electrolytic tank is also provided with a control chamber used for installing a power supply, a switch, a control circuit board and the like; the upper part is a water storage tank, the bottom of the water storage tank is an upper cover of the electrolytic cell and the control chamber, a sealing rubber ring is arranged between the upper cover and the electrolytic cell, two gas output pipes in the water storage tank penetrate through the upper cover and the lower bottom of the water storage tank, the lower ends of the two pipes are respectively communicated with the two parts of the electrolytic cell correspondingly, and the upper ends of the two pipes penetrate through the upper cover of the water storage tank and are used for outputting respective corresponding gases. The bottom of the water storage tank is also provided with a water injection pipe which is inserted into the electrolytic bath and used for injecting water into the electrolytic bath, and the water injection pipe is internally provided with a floater used for controlling the water level in the electrolytic bath. The upper cover of the water storage tank is provided with a water adding hole for adding water into the water storage tank. When the water-saving device is used, the water storage tank is filled with water, the water is injected into the electrolytic bath through the water injection pipe, and after the water level in the electrolytic bath rises to a certain height, the floater blocks the water injection pipe, and the water injection is stopped. The machine is connected with a power supply and a power switch is turned on, and the positive pole and the negative pole of direct current are respectively added to the two groups of electric plate plates in the electrolytic cell, so that water is decomposed into hydrogen and oxygen under the action of the direct current and the hydrogen and the oxygen are respectively output by respective gas output pipes. Oxygen is generated in the part of the electrolytic cell where the anode electrode plate is positioned, the oxygen is sent to the electric fan by the oxygen output pipe and is directly blown to the room, and the cathode electrode plateis positionedThe hydrogen is generated in the part of the electrolytic cell and is sent to the hydrogen exhaust soft conduit by the hydrogen output pipe and is directly led to the outside for discharging. When the water level of the electrolytic bath descends, the floater also descends, the water injection pipe is opened to continuously inject water into the electrolytic bath, after the water level rises, the floater plugs the water injection pipe again, the water injection is stopped, and the loop is traced. Only when the water in the water storage tank is used up and the water level in the electrolytic cell is reduced to a certain degree, the water surface is firstly separated from the electrode plate. The water is no longer electrolyzed into gas and the water level does not drop. At this time, the water surface does not bottom on the lower end of the gas separation plate, so that the gas in the two electrolytic cells is separated. Therefore, the machine can continuously generate oxygen as long as the power supply is input and the water storage tank is not interrupted, thereby achieving the purpose of continuously providing oxygen for breathing for people.

By adopting the scheme, the machine has the advantages of compact structure, simple production process, elegant appearance, convenience in installation and use and the like.
