Embodiment Construction

[0015] Below, combine figure 1 and 2 The oxygen generator of the present invention will be described in detail.

[0016] like figure 1 and 2 As shown, the oxygen generator of the present invention includes a shell composed of a front shell 11 and a rear shell 12 connected to each other, a core assembly 2 and a controller (not shown in the figure) arranged in the shell.

[0017] The movement assembly 2 includes an air compressor 21, a nitrogen absorption device 22 and an oxygen separation device 23, and the exhaust end of the air compressor 21 is communicated with the intake end 221 of the nitrogen absorption device 22 through an air intake valve 24, and is passed through a controller 3 Control the working state of the intake valve 24 to control the on and off of the gas passage between the air compressor 21 and the nitrogen absorption device 22, and then control the exhaust volume of the air compressor 21, that is, control the air compressor 21 to discharge nitrogen The am...

Abstract

The invention relates to the field of oxygen preparation, particularly a device for preparing oxygen. In order to solve the problem that the existing oxygen generator can not prepare high-concentration oxygen at different heights above sea level, the invention provides an oxygen generator which comprises a shell, a core assembly and a controller, wherein the core assembly comprises an air compressor, a nitrogen absorption unit and an oxygen separation device; the air compressor communicates with the nitrogen absorption unit through a gas inlet valve; compressed air output by the air compressor enters the nitrogen absorption unit through the gas inlet valve; the oxygen separation device communicates with the nitrogen absorption unit; an atmospheric pressure detection device for detecting atmospheric pressure is arranged in the controller; and a control signal is output according to the detected atmospheric pressure to control the air discharge amount of the air compressor and the gas inlet-gas outlet switching time of the oxygen separation device. The oxygen generator is applicable to different atmospheric pressure environments, and can prepare the high-concentration oxygen at different heights above sea level.

Description

technical field [0001] The invention relates to the field of oxygen preparation, in particular to a device for preparing oxygen. Background technique [0002] Oxygen is an indispensable substance to maintain human life. However, in some special cases, people have to face an environment lacking oxygen, or require a higher concentration of oxygen. In order to meet the above needs, those skilled in the art have developed an oxygen generator equipment. [0003] At present, the commonly used oxygen generators on the market use molecular sieve physical adsorption and desorption technology to separate nitrogen and oxygen in the air, so as to obtain high-concentration oxygen. However, as the altitude increases, the oxygen content in the air becomes thinner and thinner. The existing oxygen generator cannot detect the oxygen content in the air, and thus cannot meet the requirements for preparing high-concentration oxygen at different altitudes. Require.
