Oxygen therapy has become an important treatment and rehabilitation health care method in wards and community rehabilitation, and has gradually entered the home environment. Oxygen storage products such as oxygen tanks and oxygen bottles are extremely inconvenient to use, so oxygen concentrators came into being. Oxygen concentrators are 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 various components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate it into oxygen and nitrogen.
[0003] Existing oxygen concentrators will generate certain noise during operation. Since oxygen concentrators are usually used indoors and users usually use them when sleeping or resting, the noise generated by the operation of the oxygen concentrators will affect the sleep of users.

[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.
[0024] An oxygen concentrator with a noise reduction structure according to an embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
[0025] Example 1
[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of an oxygen concentrator with a noise reduction structure, comprising a housing 1, a noise reduction mechanism is arranged inside the housing 1, and a noise reduction shell 3 is arranged on one side of the housing 1;
[0027] The noise reduction mechanism includes a sound insulation shell 6, a telescopic hose 5 and a buffer 8. An oxygen concentrator body 13 is installed inside the sound insulation shell 6. The buffer 8 is fixedly installed between the sound insulation shell 6 and the inner wall of the shell 1. There are several buffers 8. An input end 4 is fixedly installed on one side of the shell 1, and an output end 2 is fixedly installed on the other side of the shell 1. The input end 4 and the output end 2 are both connected to the connecting end of the oxygen concentrator body 13 through the telescopic hose 5.
[0028] It should be noted that by providing a sound insulation shell 6 and installing the oxygen concentrator body 13 on the inner wall of the sound insulation shell 6, the noise emitted when the oxygen concentrator body 13 is in operation can be reduced. By providing a buffer 8, it can be avoided that when the oxygen concentrator body 13 inside the sound insulation shell 6 vibrates during operation, it will not collide with the inner wall of the shell 1 or cause resonance of the shell 1, thereby reducing the generation of noise. By providing a telescopic hose 5, the connection between the oxygen concentrator body 13 and the output end 2 and the input end 4 can be ensured when the sound insulation shell 6 is shaken.
[0029] In some embodiments, Figure 4 As shown, the buffer member 8 includes two connecting members 801, a mounting column 802 and a second spring 803. The two connecting members 801 are slidably connected to the side walls at both ends of the mounting column 802, and the second spring 803 is fixedly installed between the inner wall of the connecting member 801 and one end of the mounting column 802.
[0030] It should be noted that the second spring 803 can play a buffering role.
[0031] In some embodiments, Figure 2 As shown, the gap between the sound insulation shell 6 and the inner wall of the shell 1 forms a noise reduction chamber 12, the outside of the sound insulation shell 6 is a sound insulation felt, and the inside of the sound insulation shell 6 is a wave peak sound absorbing sponge.
[0032] It should be noted that by setting the noise reduction chamber 12, the noise inside the shell 1 can be prevented from being transmitted, by setting the outside of the sound insulation shell 6 as sound insulation felt, the sound insulation shell 6 can be easier to install, and by setting the inside as a wave peak sound-absorbing sponge, the noise reduction effect can be increased.
[0033] Example 2
[0034] In some embodiments, Figure 2 , Figure 3 As shown, the noise reduction shell 3 includes a protective layer 301 and a sound absorbing layer 302, the sound absorbing layer 302 is fixedly installed inside the protective layer 301, a plurality of grooves 303 are provided inside the sound absorbing layer 302, an air inlet 7 matching the input end 4 is provided at the bottom of the noise reduction shell 3, a first spring 9 is fixedly installed inside the shell 1, a card block 10 is fixedly installed at one end of the first spring 9, the card block 10 is movably connected to the inside of the shell 1 through the first spring 9, and a card slot 11 matching the card block 10 is provided on one side of the noise reduction shell 3.
[0035] It should be noted that by providing the first spring 9 and the block 10, the noise reduction shell 3 can be quickly installed or disassembled, and by providing the protective layer 301, the protective effect of the noise reduction shell 3 can be increased. By opening a plurality of grooves 303 inside the sound-absorbing layer 302, the noise generated by the input end 4 can be gradually reduced and eliminated inside the noise reduction shell 3, thereby increasing the noise reduction effect.
[0036] The oxygen generator body 13 in the present invention is a well-known component and will not be described in detail here.
[0037] Working principle: When in use, the noise generated by the input end 4 can be gradually reduced and eliminated inside the noise reduction shell 3 through the noise reduction shell 3, thereby increasing the noise reduction effect. By arranging the sound insulation shell 6 and installing the oxygen concentrator body 13 on the inner wall of the sound insulation shell 6, the noise transmitted from the operation of the oxygen concentrator body 13 can be reduced. By arranging the buffer 8, the vibration generated by the operation of the oxygen concentrator body 13 inside the sound insulation shell 6 can be avoided, which will avoid the collision with the inner wall of the shell 1 or cause the resonance of the shell 1, thereby reducing the generation of noise, thereby avoiding affecting the users when the oxygen concentrator is in operation.
[0038] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
