Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to an oxygen concentrator that is easy to maintain. Background Art

[0002] As an electrical device for obtaining a certain concentration of oxygen, an oxygen concentrator uses air separation technology to compress, filter and separate the external air to obtain a certain concentration of oxygen. With the maturity and development of oxygen production technology, there are not only industrial oxygen concentrators on the market, but also some simple household oxygen concentrators.

[0003] To this end, the patent specification with publication number CN214990276U discloses an oxygen concentrator, comprising a shell with heat dissipation holes, a compressor and a heat dissipation structure arranged in the shell, the compressor and the molecular sieve are connected, the compressor presses the air into the molecular sieve through the heat dissipation structure to separate the oxygen, and a noise reduction structure is arranged on one side of the heat dissipation hole, thereby reducing the noise generated by the oxygen concentrator. The utility model provides an oxygen concentrator, in which the compressor, molecular sieve and heat dissipation structure are all arranged in the shell, heat dissipation holes are opened on the shell, and a noise reduction structure is arranged between the heat dissipation holes and the compressor. The noise reduction structure generates an anti-phase wave equal to the noise such as the compressor noise and the aerodynamic noise, weakens the noise generated in the oxygen concentrator, and further reduces the noise of the oxygen concentrator itself. The above-mentioned oxygen concentrator has good stability when in use, but there are still some problems:

[0004] 1. When the above-mentioned oxygen concentrator is in use, it needs to draw in external air for compression and subsequent processing. There are some floating objects or dust in the air. If it is not initially filtered, it is easy to cause dirt to appear on the pipes and inner walls of the components of the oxygen concentrator, thereby affecting the quality of oxygen.

[0005] 2. Most of the components of the above oxygen concentrator are installed inside the shell, which makes it inconvenient to disassemble the shell when repairing and disassembling the internal parts. Utility Model Content

One side of both ends of the interior of the oxygen concentrator main body 1 is fixedly connected with a fixing block 603, and one end of the interior of the fixing block 603 is provided with a spring clip 604. Guide rails 605 are opened at both ends of the interior of the oxygen concentrator main body 1.

[0025] Refer to the attached Figure 1 and Figure 2The shells of most common oxygen concentrators are not easy to open, which makes it inconvenient to perform maintenance and disassemble and replace components in the oxygen concentrator. For this reason, the front end of the oxygen concentrator body 1 is designed to be open. When the oxygen concentrator needs to be maintained, the baffle 601 can be opened from one side. When the oxygen concentrator is in use, the baffle 601 can be inserted into the front end of the oxygen concentrator body 1 through the bottom groove along the guide rail 605, and the spring at one end of the spring clip 604 is engaged with the positioning hole 602, so that the baffle 601 is easy to disassemble and install, thereby making subsequent maintenance and parts replacement more convenient.

[0026] A filter structure 11 is provided on one side of the oxygen concentrator body 1. The filter structure 11 includes a mounting groove 1101, a socket 1102, a magnet sheet 1103, a water bottle 1104, an air inlet pipe 1105, an air outlet pipe 1106, a metal base 1107, a magnet ring 1108 and a filter frame 1109.

When the oxygen generator is in use, the outside air will be preliminarily filtered by the clean water in several water bottles 1104, so that the suspended matter or dust in the air is adsorbed by the clean water, thereby avoiding the subsequent adsorption of dirt on the inner wall of the pipe or device. At the same time, the filter frame 1109 installed on the inner side of the air intake pipe 1105 is adsorbed and installed with the metal air intake pipe 1105 through the magnet ring 1108, so that some larger particles of suspended matter or dust are filtered by the filter frame 1109, thereby avoiding the phenomenon of blockage caused by dirt accumulation in the pipe.
