[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0028] The utility model embodiment provides an oxygen concentrator, such as Figures 1 to 3 As shown, it includes a base 10, a first compressor 210, a second compressor 220, a first silencer 310 and a second silencer 320, and an air port 101 is formed on the base 10; the first compressor 210 and the second compressor 220 are both arranged on the base 10; the air outlet of the first silencer 310 is sealedly connected to the air inlet of the first compressor 210, and the air outlet of the second silencer 320 is sealedly connected to the air inlet of the second compressor 220, and the first silencer 310 and the second silencer 320 are located in the base 10; wherein, the air inlet of the first silencer 310 and the air inlet of the second silencer 320 are respectively connected to the external air through the air port 101.

[0029] The first compressor 210 and the second compressor 220 are arranged on the base 10, and the base 10 is used to provide a stable installation environment. The sealed connection between the first silencer 310 and the first compressor 210 and the sealed connection between the second silencer 320 and the second compressor 220 can effectively prevent external air from leaking at the connection point, thereby ensuring the working efficiency of the oxygen concentrator. The arrangement of the first silencer 310 and the second silencer 320 can reduce the flow noise generated when the first compressor 210 and the second compressor 220 are working, and the flow noise generated when the external air passes through the first compressor 210 and the second compressor 220, thereby reducing the overall noise when the oxygen concentrator is in use, which is beneficial to the user's rest and recovery during physical therapy and treatment, and improves the user's use experience.

[0030] As a preferred solution of this embodiment, refer to Figure 4 and Figure 5 A plurality of first silencer cavities 301 arranged in a straight line are formed in the first silencer pipe 310, and the plurality of first silencer cavities 301 are all connected to the air inlet of the first silencer pipe 310; a plurality of second silencer cavities 302 arranged in a straight line are formed in the second silencer pipe 320, and the plurality of second silencer cavities 302 are connected to the air inlet of the second silencer pipe 320.

[0031] Among them, when the first compressor 210 or the second compressor 220 is working, during the process of air being transported along the first silencer pipe 310 or the second silencer pipe 320, when passing through the multiple first silencer cavities 301 arranged in a straight line formed in the first silencer pipe 310 or the multiple second silencer cavities 302 arranged in a straight line formed in the second silencer pipe 320, the propagation and diffusion of noise can be reduced, thereby reducing the flow noise generated when the air passes through the first compressor 210 and the second compressor 220. This embodiment achieves the purpose of silencing through the setting of the first silencer cavity 301 and the second silencer cavity 302.

[0032] As a preferred solution of this embodiment, refer to Figure 4 and Figure 5 The first silencer pipe 310 and the second silencer pipe 320 are both in an "L"-shaped structure. The first silencer pipe 310 includes a first tube body 311 and a second tube body 312 that are connected.

The third tube body 321 is sealed and connected to the second compressor 220, and a second silencer cavity 302 is formed in the fourth tube body 322.

[0033] Here, a structural form of the first silencer pipe 310 and the second silencer pipe 320 is provided. The setting of the "L"-shaped structure can reduce the setting space of the first silencer pipe 310 and the second silencer pipe 320 in the oxygen concentrator and reduce the overall volume of the oxygen concentrator. Specifically, the first silencer pipe 310 includes a first tube body 311 and a second tube body 312, and a sealed connection between the first silencer pipe 310 and the first compressor 210 is achieved through the first tube body 311. A first silencer cavity 301 is formed in the second tube body 312. The air achieves the purpose of silence after passing through the second tube body 312 and is transported to the first compressor 210 along the first tube body 311; the second silencer pipe 320 includes a third tube body 321 and a fourth tube body 322, and a sealed connection between the second silencer pipe 320 and the second compressor 220 is achieved through the third tube body 321. A second silencer cavity 302 is formed in the fourth tube body 322. The air achieves the purpose of silence after passing through the fourth tube body 322 and is transported to the second compressor 220 along the third tube body 321.

[0034] As a preferred solution of this embodiment, the first silencer pipe 310 and the second silencer pipe 320 are made of silencer material.

[0035] Among them, the sound-absorbing material can effectively absorb the energy of sound waves, further reduce the noise generated by air flow, and further reduce the overall noise when the oxygen concentrator is in use, which is beneficial for the user's rest and recovery during physical therapy and treatment, and improves the user's experience.

[0036] The sound-absorbing material in this embodiment can be rubber, which has good sound absorption performance and is often used for sound insulation.

The setting of the first buffer 410 and the second buffer 420 can reduce the vibration of the first compressor 210 or the second compressor 220 when working, thereby reducing the noise generated by the vibration, and further reducing the overall noise of the oxygen concentrator when in use, which is beneficial to the user's rest and recovery during physical therapy and treatment, and improves the user's user experience.

[0039] The first buffer 410 and the second buffer 420 can be made of elastic material, which has a good shock-absorbing effect, reduces the transmission of sound and vibration, and can protect the oxygen concentrator while reducing the noise level and prolong the service life of the oxygen concentrator. The elastic material can be rubber, foam, etc., which is not specifically limited here.

[0040] The installation cavity 1103 is set to provide a stable installation environment for the first silencer 310 and the second silencer 320, thereby improving the overall installation integration of the oxygen concentrator. An air port 101 is formed on the installation seat 110 to connect the first silencer 310 and the second silencer 320 with the external air, thereby ensuring the smoothness and continuity of the operation of the oxygen concentrator.
