Description

Technical Field

[0001] The utility model relates to the technical field related to oxygen concentrators, and in particular to an oxygen concentrator. Background Art

[0002] An oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then further distilled to obtain the oxygen. It is a new type of equipment that extracts oxygen from the air based on pressure swing adsorption technology. It uses molecular sieve physical adsorption and desorption technology to load molecular sieves in the oxygen generator. When pressurized, it can adsorb nitrogen in the air, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The entire oxygen production process is a physical adsorption process, without chemical reaction, and the raw material is air.

[0003] At present, the existing oxygen concentrators generate a lot of noise during operation. Usually, users who need oxygen are not in ideal physical condition and need a quiet rest environment. However, the oxygen concentrators make a lot of noise when working, and their noise reduction effect is not very good. The sound when the noise is transmitted to the user is still loud, and it is impossible to provide users with a comfortable oxygen environment. Utility Model Content

The rod 12 is slidably connected. In order to prevent the noise generated by the oxygen concentrator body 11 from being transmitted from the shell 1, a sound insulation cotton 3 is fixedly attached to the inner surface of the cavity 2. The vibration generated by the oxygen concentrator body 11 is offset by the shock absorbing spring 7 and the damper on the one hand, and on the other hand, the slide rod 8 and the guide rod 12 are driven to slide back and forth on the noise reduction box 4 and the fixing member 21 respectively.

The other end of the air intake pipe 14 extends into the cavity 2 and is fixedly connected to the telescopic hose 19. The telescopic hose 19 has a certain extensibility. The filter tube 16, the air intake pipe 14 and the telescopic hose 19 are collectively referred to as the air intake pipe 2.

By providing the dust cover 23, dust in the air can be prevented from entering the shell 1 through the heat dissipation pipe 20, thereby avoiding damage to the oxygen generator.

[0029] Working principle:

[0030] In actual use, firstly, the universal wheel 25 cooperates with the handle 24 to move the housing 1 to the specified position, and the filter tube 16 is fixed on the air inlet pipe 14 by twisting it, and the filter plate 18 in the filter tube 16 can filter impurities in the air. Secondly, the oxygen generator body 11 starts to work, and the air outside the housing 1 is filtered through the filter tube 16, and then flows into the oxygen generator body 11 through the telescopic hose 19 for oxygen production. The oxygen generator body 11 will generate vibration during operation, and the vibration is transmitted to the slide bar 8 through the support plate 9, and then the slide bar 8 is transmitted downward to the shock absorbing spring 7, and the shock absorbing spring 7 receives the oxygen generator body. After the vibration force of the body 11 is absorbed by the fan 22, the vibration force is offset by its own scaling, which further plays a buffering role on the oxygen concentrator body 11, effectively preventing the noise generated by the oxygen concentrator body 11 from being transmitted from the inside of the shell 1, thereby playing a role in noise reduction. At the same time, the fan 22 works, and the fan 22 flows the heat generated by the oxygen concentrator body 11 to the outside of the shell 1 through the heat dissipation pipe 20, thereby preventing the electronic components in the shell 1 from being burned by high temperature and affecting the normal use of the oxygen concentrator. By providing a dust cover 23, dust in the air can be prevented from entering the shell 1 through the heat dissipation pipe 20, thereby avoiding damage to the oxygen concentrator.
