[0002] Currently, oxygen concentrators on the market usually include compressor components, molecular sieve components, valve components, oxygen pipe components, etc. The oxygen concentrator compresses the air through the compressor to increase the air pressure, and then transports it to the molecular sieve component for oxygen and nitrogen separation.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention, and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of it.

[0057] like Figure 1As shown, the embodiment of the present disclosure discloses an oxygen concentrator 1000 which generally includes an oxygen concentrator body 200. The oxygen concentrator body 200 includes a compressor assembly (not shown in the figure), a molecular sieve assembly (not shown in the figure), a valve assembly (not shown in the figure), an oxygen pipe assembly (not shown in the figure), etc. The oxygen concentrator 1000 compresses the air to increase the air pressure through the compressor, and then transports it to the molecular sieve assembly for oxygen and nitrogen separation. The separated oxygen is transported to the user's mouth and nose through the oxygen pipe. When one molecular sieve has adsorbed all the oxygen, the valve assembly switches and inputs the compressed air into another molecular sieve assembly. Since the specific structure of the oxygen concentrator 1000 that can realize the oxygen production function is a relatively mature technology in this field, the embodiment of the present disclosure does not elaborate on the corresponding structure of the oxygen concentrator 1000. All oxygen concentrators 1000 that can realize the oxygen production function are within the protection scope of the embodiment of the present disclosure.

[0058] It should be noted that during the operation of the oxygen concentrator 1000, the compressor components, valve components, etc. will generate significant vibration and noise. Users of the oxygen concentrator 1000 often have various underlying diseases and poor sleep quality. When the oxygen concentrator 1000 works at night, the noise generated will cause users to feel obvious discomfort and difficulty falling asleep, affecting the user's physical and mental health. In order to solve the above problems, Figure 1 and Figure 2 As shown, the oxygen concentrator 1000 also includes a sound insulation device 100, which is covered on the periphery of the oxygen concentrator body 200 to prevent the noise generated by the compressor assembly, valve assembly, etc. from being transmitted outward, thereby preventing the user from being greatly affected during use and ensuring the user's physical and mental health.

[0059] It should be noted that the oxygen concentrator body 200 will generate a large amount of heat when working. However, due to the setting of the sound insulation device 100, the large amount of heat generated by the oxygen concentrator body 200 cannot be dissipated well, which is not conducive to the effective and good heat dissipation of the oxygen concentrator 1000. The overall temperature of the oxygen concentrator 1000 is high, which affects the performance and use effect of the oxygen concentrator 1000. The oxygen concentrator 1000 will also malfunction in a long-term high temperature environment, reducing the service life of the oxygen concentrator 1000.

[0060] In order to solve the above problems, Figure 1As shown, the sound insulation device 100 of the embodiment of the present disclosure further includes a gas driving mechanism 20, the sound insulation cover 10 includes a top plate 111 and a bottom plate 121, the top plate 111 is arranged on the upper part of the sound insulation cover 10, and the bottom plate 121 is arranged on the lower part of the sound insulation cover 10, a first gas inlet 1111 is opened on the top plate 111, and a gas outlet 1211 is opened on the bottom plate 121, the oxygen generator body 200 is arranged inside the sound insulation cover 10, and the gas driving mechanism 20 is used to make the gas outside the sound insulation cover 10 flow through the first gas inlet 1111 and the inside of the sound insulation cover 10 in sequence, and then be discharged from the gas outlet 1211. Under the drive of the gas driving mechanism 20, the outside of the sound insulation cover 10 The gas can enter from the first gas inlet 1111 and be discharged from the gas outlet 1211. The gas outside the soundproof cover 10 can flow from top to bottom to various positions inside the soundproof cover 10. The path of the gas outside the soundproof cover 10 is longer. The gas outside the soundproof cover 10 can effectively and well cool down and dissipate heat at various positions of the oxygen concentrator main body 200, thereby improving the gas flow on the surface of the oxygen concentrator main body 200, achieving a better heat dissipation effect on the oxygen concentrator main body 200, effectively reducing the temperature of the entire oxygen concentrator 1000, ensuring that the oxygen concentrator 1000 always has good performance and use effect, and effectively improving the service life of the oxygen concentrator 1000.

[0061] In summary, the oxygen concentrator 1000 of the embodiment of the present disclosure can ensure low noise operation while also having good heat dissipation effect, usage effect and long service life.

[0062] In addition, since the gas outlet 1211 is provided on the bottom plate 121, the gas discharged from the gas outlet 1211 is directed toward Figure 1 The ground 2000 shown is sprayed, and the gas discharged from the gas outlet 1211 will not be blown directly to the user, which effectively improves the user's experience.

[0063] It should be noted that if Figure 1 and Figure 2 As shown, the gas drive mechanism 20 of the embodiment of the present disclosure can be a fan, a centrifugal fan, an axial flow fan, a diagonal flow fan, a rotary fan, an air pump and other structures. All gas drive mechanisms 20 that can enable the gas outside the soundproof cover 10 to flow through the first gas inlet 1111 and the interior of the soundproof cover 10 in sequence and be discharged from the gas outlet 1211 are within the protection scope of the embodiment of the present disclosure. The embodiment of the present disclosure only lists a limited number of types of gas drive mechanisms 20 for explanation.

[0064] In an optional embodiment, if Figure 1As shown, the oxygen concentrator body 200, the gas drive mechanism 20 and the gas outlet 1211 are arranged in sequence from top to bottom, which can enable a large amount of gas outside the sound insulation cover 10 to flow well from the first gas inlet 1111 to the gas outlet 1211, and can also achieve a close arrangement of the oxygen concentrator body 200 and the gas drive mechanism 20 in the up and down directions, thereby achieving a compact arrangement of various parts of the oxygen concentrator 1000, ensuring that the overall volume of the oxygen concentrator 1000 is small, facilitating the reasonable arrangement of the oxygen concentrator 1000 in a small space, and also facilitating the user's quick and convenient movement of the oxygen concentrator 1000, thereby improving the user's experience of using the oxygen concentrator 1000.

[0065] In an optional embodiment, if Figure 1 As shown, the exhaust volume of the gas drive mechanism 20 is the first air volume Q1, and the oxygen production volume of the oxygen concentrator body 200 is the second air volume Q2. Among them, the first air volume Q1 is greater than the second air volume Q2, which is beneficial to the flow of gas in the soundproof cover 10 and achieves a better heat dissipation effect on the oxygen concentrator body 200.

[0066] For example, It can achieve better flow of gas in the soundproof cover 10, so as to achieve better heat dissipation effect of the gas in the soundproof cover 10 on the oxygen concentrator body 200. It can be 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, etc. It should be noted that the above numerical values ​​are only limited examples, and all point values ​​or range values ​​within the range of 10 to 100 are within the protection scope of this optional embodiment.

[0067] In an optional embodiment, if Figure 1 and Figure 3As shown, the sound insulation device 100 also includes a shock-absorbing mechanism 30, which is disposed between the base plate 121 and the oxygen concentrator body 200. The provision of the shock-absorbing mechanism 30 can effectively reduce vibration of the oxygen concentrator body 200 and noise during use, achieving a quieter experience for the user and enhancing the user's experience of the oxygen concentrator 1000. Exemplarily, the shock-absorbing mechanism 30 can be a plate-like structure made of materials such as rubber or silicone. The shock-absorbing mechanism 30 is applied to the upper surface of the base plate 121, and the oxygen concentrator body 200 is disposed above the shock-absorbing mechanism 30. Furthermore, the shock-absorbing mechanism 30 can also include multiple shock-absorbing springs capable of vertical expansion and contraction. The provision of the shock-absorbing springs can also provide a shock-absorbing and buffering effect for the oxygen concentrator body 200. Furthermore, the shock-absorbing mechanism 30 can also include multiple shock-absorbing blocks, which can be made of rubber or silicone. Furthermore, the shock absorbing mechanism 30 may also include, for example, multiple shock absorbing cylinders arranged along a horizontal plane. These multiple shock absorbing cylinders can achieve a good shock absorbing and buffering effect for the oxygen concentrator body 200 at various positions along the horizontal plane, thereby preventing the oxygen concentrator body 200 from tilting during use and ensuring that the oxygen concentrator body 200 always maintains a good performance. It should be noted that the aforementioned shock absorbing mechanisms 30 are only examples of a limited number of types, and all structures capable of achieving shock absorbing and buffering for the oxygen concentrator body 200 in the vertical direction are within the scope of protection of this optional embodiment.
