Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figure 1, the oxygen supply system for oxygen generator micro-negative pressure environment comprises an oxygen generator 11, an air inlet pipeline 6 and an oxygen delivery pipeline 1, wherein the oxygen generator 11 is arranged at the outdoor side of an aerobic space 3, the outlet of the air inlet pipeline 6 is communicated with the air inlet of the oxygen generator 11, the inlet of the air inlet pipeline 6 is connected with the aerobic space 3, the first end of the oxygen delivery pipeline 1 is communicated with the air outlet of the oxygen generator 11, the second end of the oxygen delivery pipeline 1 is communicated with the aerobic space 3, the flow rate of the extracted air from the aerobic space 3 of the oxygen generator 11 is larger than the flow rate of the input air from the oxygen generator 11 to the aerobic space, at the moment, a negative pressure is formed in the aerobic space 3 because the extraction of the air flow rate is larger than the input air, the oxygen is prevented from being sent into the aerobic space by a high-pressure mode, and the problem of the oxygen in the aerobic space 3 caused by the fact that the pressure in, and the carbon dioxide in the aerobic space 3 can be simultaneously pumped out to reduce the concentration of the carbon dioxide in the aerobic space 3, thereby achieving the purpose of negative pressure oxygen supply, because the aerobic space 3 is under the condition of negative pressure, partial air can be sucked from the outside, and the oxygen demand of the aerobic space 3 can be satisfied even if the oxygen generator 11 does not suck gas from the outside atmosphere.

The oxygen generator 11 comprises a compressor 9, an air suction port of the compressor 9 forms an air inlet of the oxygen generator 11, the air suction port of the compressor 9 sucks air to enable the aerobic space 3 to form negative pressure, and pressure of the compressor 9 is utilized to provide pressure for an oxygen generation module 10 in the oxygen generator 11, so that the oxygen generation module 10 can generate oxygen conveniently.

The inlet of the air inlet pipeline 6 is provided with an air inlet filter 4, so that dust and the like at the inlet of the air inlet pipeline 6 (inside the aerobic space 3) are removed, and the working reliability of the oxygen generator 11 is protected.

The air inlet filter 4 comprises a filter screen 5, and the filter screen 5 can be arranged at the inlet of the air inlet pipeline 6 in a drawing and inserting mode.

An inlet silencer 8 is arranged at the outlet of the air inlet pipeline 6, so that noise generated by structures such as an oxygen generator 11 is reduced and enters the aerobic space 3 through the air inlet pipeline 6.

Oxygen generator micro-negative pressure environment oxygen system still includes atmosphere air intake branch pipe 7, the one end of atmosphere air intake branch pipe 7 with air intake pipe 6 intercommunication, the other end of atmosphere air intake branch pipe 7 with the outside air intercommunication in aerobic space 3, when atmosphere air intake branch pipe 7 is opened, external atmosphere gets into compressor 9 by atmosphere air intake branch pipe 7, can absorb the air from the external world and make oxygen jointly when the oxygen concentration in air intake pipe 6 can't reach the oxygen production demand to guarantee oxygen concentration reaches the settlement requirement in oxygen therapy pipeline 1, when atmosphere air intake branch pipe 7 closed, compressor 9 only breathes in by aerobic space 3.

The working process is as follows: after the start-up, the compressor 9 extracts gas from the aerobic space 3, and the compressed gas passes through the oxygen generation module 10 to separate oxygen, and then the oxygen is conveyed back to the aerobic space 3 through the oxygen conveying pipeline 1. The slightly negative pressure in the aerobic space 3 is caused by the fact that the flow of the withdrawn gas is greater than the flow of the returned gas. Meanwhile, the carbon dioxide and the nitrogen in the extracted gas are discharged into the atmosphere, so that the aim of discharging the carbon dioxide is fulfilled. The slight negative pressure in the aerobic space 3 causes the atmospheric air to flow into the aerobic space 3, effectively preventing the oxygen from diffusing to the outside.
