It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figure 1-Figure 5As shown, an oxygen concentrator with good mute effect includes an installation box 1, and an oxygen concentrator body 2 installed on the top of the installation box 1, an oxygen outlet pipe 3 is installed at the oxygen outlet of the oxygen concentrator body 2, two sound insulation covers 4 are provided with slots 15 for use with the oxygen outlet pipe 3 on one side close to the oxygen outlet pipe 3, the outer cover of the oxygen concentrator body 2 is provided with two sound insulation covers 4, and two universal wheels 8 are installed at the bottom of the sound insulation covers 4. Foot brakes are provided on the two universal wheels 8. When the driving mechanism drives the sound insulation cover 4 to move, the universal wheels provided 8 can not only play a supporting role, but also make it more convenient to push the sound insulation cover 4 to move. The inner walls of the two sound insulation covers 4 are installed with sound-absorbing cotton 6. When the oxygen generator body 2 is in use, the two sound insulation covers 4 will cover the oxygen generator body 2, thereby playing a sound insulation role. The sound-absorbing plate 6 can further achieve the sound-absorbing effect, so that the sound-absorbing effect is better. The bottom of the two sound insulation covers 4 is provided with a strip opening 5 used in conjunction with the installation box 1. The interior of the installation box 1 is equipped with a device that drives the two sound insulation covers 4 to lean against each other. A driving mechanism for moving near or away from one side, the driving mechanism includes two threaded rods 9 rotatably connected to the inside of the installation box 1, two threaded sleeves 10 threadedly connected to the outside of the two threaded rods 9, and two push plates 11 respectively installed on one side of the two threaded sleeves 10, one end of the two push plates 11 extends to the outside of the installation box 1 and is respectively fixedly connected to one side of the two strip-shaped openings 5, a rotating mechanism for driving the two threaded rods 9 to rotate is installed in the installation box 1, the rotating mechanism includes a rotating motor 14 installed on the inner wall of one side of the installation box 1, a first gear 13 installed at the output end of the rotating motor 14, and two second gears 12 respectively installed on the outside of the two threaded rods 9 and meshing with the first gear 13, two support blocks are installed at the bottom of the installation box 1, and a plurality of heat dissipation holes 7 are opened on the top and bottom of the installation box 1, and the airflow inside and outside the sound insulation cover 4 can flow through the heat dissipation holes, so as to avoid the problem of poor heat dissipation effect caused by the closed internal space when the sound insulation cover 4 covers the oxygen generator body 2.

[0021] It should be noted that, when this oxygen concentrator with good silent effect needs to be repaired during use, the rotating motor 14 will drive the first gear 13 to rotate, and under the meshing of the first gear 13 and the second gear 12, the two threaded rods 9 will rotate, and the threaded sleeve 10 will move under the drive of the threaded rod 9, and then the push plate 11 will be pushed to move, and under the action of the two push plates 11, the two sound insulation covers 4 will move to the side away from each other, thereby exposing the oxygen concentrator body 2 in the sound insulation cover 4, and when the sound insulation cover 4 moves to both sides of the oxygen concentrator body 2, the driving mechanism can continue to drive the sound insulation cover 4 to move, so that the sound insulation cover 4 can be moved to a position where it does not hinder the maintenance personnel from performing maintenance.

[0022] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
