DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides an oxygen concentrator with an internal cleaning structure, such as Figure 1-4 As shown, the oxygen concentrator with an internal cleaning structure includes: an oxygen concentrator body 1 and a water tank 2, wherein the water tank 2 is arranged on the oxygen concentrator body 1; a tank cover 3 arranged on the water tank 2; a cleaning brush 4 arranged in the water tank 2 for cleaning the inner wall of the water tank 2; a lifting and lowering assembly frame 7 arranged in the tank cover 3; a motor 5 fixed on the assembly frame 7 for driving the cleaning brush 4 to rotate, and a connecting shaft 6 for assembling the cleaning brush 4 is arranged on the output shaft of the motor 5; an annular flushing pipe 11 fixed on the assembly frame 7 for spraying water to flush the inner wall of the water tank 2, and a plurality of nozzles 12 are fixedly connected to the annular flushing pipe 11; and an adjusting mechanism arranged on the tank cover 3 for regulating the lifting and lowering of the assembly frame 7.

[0022] It should be noted that during the use of the oxygen concentrator, the water tank is a vital component, which is responsible for humidifying oxygen during the oxygen production process and ensuring that the output oxygen humidity meets the standards for medical or household needs. However, with the passage of time and continuous operation, impurities such as dust and scale will gradually accumulate on the inner wall of the water tank. The sources of these impurities may be dust in the air, microorganisms, minerals and organic matter in the water, etc. These accumulated impurities will first have a negative impact on the humidification performance of the water tank. When impurities adhere to the inner wall of the water tank, they will reduce the effective humidification area of ​​the water tank, thereby reducing the humidification effect. This results in insufficient humidity of the output oxygen, which may not meet the needs of medical or household use, especially in occasions with strict requirements on oxygen humidity; more seriously, these impurities may also pose a threat to the overall operation of the oxygen concentrator. For example, when impurities accumulate to a certain extent, they may block key pipelines in the oxygen concentrator, such as the water pipeline or the gas-liquid separator. This blockage will hinder the normal flow of gas and liquid, resulting in a decrease in the performance of the oxygen concentrator or even complete failure; in addition, impurities may also affect the separation efficiency of the gas-liquid separator. The gas-liquid separator is a key component in the oxygen concentrator for separating oxygen and liquid water. If its inner wall is covered with impurities, its separation efficiency will be reduced, resulting in the output oxygen containing too much liquid water or other impurities, further affecting the quality and safety of the oxygen; in response to these problems, the traditional manual disassembly and cleaning methods have many disadvantages. First, disassembling the water tank requires a lot of time and manpower, and the operation is complicated, requiring professional knowledge and skills. Secondly, the water tank or other components may be damaged during the disassembly process, increasing maintenance costs.
