Description

Technical Field

[0001] The utility model relates to a shock-absorbing base fixing structure of an oxygen concentrator compressor, belonging to the technical field of oxygen concentrators. Background Art

[0002] Existing oxygen concentrators mainly use the principle of pressure swing adsorption technology to produce oxygen. This solution requires the use of a compressor, and the noise generated by the compressor during operation is one of the noise sources of the oxygen concentrator. Currently, the technical solution of placing the compressor on an elastic buffer base and sealing the compressor as a whole in an independent chamber is mostly used to reduce the noise generated by the compressor during operation.

[0003] The utility model with authorization announcement number CN217582426U discloses a compressor damping device, which provides a compressor damping solution. However, the assembly of the solution is complicated and is not conducive to improving the assembly efficiency of the product. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the utility model provides a shock-absorbing base fixing structure of an oxygen concentrator compressor, which helps to improve the assembly efficiency of the compressor and prevent the compressor from tipping over during assembly.

[0005] A shock-absorbing base fixing structure for an oxygen concentrator compressor comprises a first shell and a shock-absorbing base, wherein the shock-absorbing base comprises a main plate component and two side plates, the two side plates are located on the left and right sides of the main plate component, and the plane where the side plates are located is perpendicular to the plane where the main plate component is located; the side plates are provided with limiting protrusions extending in the front-rear direction, and the limiting protrusions are located on the outer side or the inner side of the side plates;

[0006] Two guide ribs extending in the front-to-back direction are provided on the first shell, and a first limiting groove extending in the front-to-back direction is provided at the end of the guide rib away from the first shell, and the opening direction of the first limiting groove is away from the first shell. The two guide ribs are located on the outer side or inner side of the two side plates, and at least a part of the limiting protrusion is inserted into the first limiting groove.

[0007] The above technical solution can simplify the assembly process of the compressor. The compressor is fixed on the shock-absorbing base through a shock-absorbing mechanism (spring, etc.). The shock-absorbing base only needs to be pushed toward the first shell to be fixed on the first shell. During the pushing process, the two guide ribs guide the two side plates of the shock-absorbing base to ensure that the shock-absorbing base moves in a predetermined direction. When the limiting protrusion is inserted into the first limiting groove, the positioning and assembly of the shock-absorbing base is realized. Among them, the oxygen concentrator also includes a second shell, the compressor is located between the first shell and the second shell, the first shell is located behind the second shell, that is, the first shell and the second shell are spaced in the front and rear directions, and the two side plates (two guide ribs) are spaced in the left and right directions. The two guide ribs limit the left and right movement of the shock-absorbing base (side plate), and the first limiting groove limits the up and down movement of the shock-absorbing base (side plate) (the first limiting groove can also prevent the shock-absorbing base from rotating relative to the first shell). Among them, when the oxygen concentrator is in use, the main plate component is roughly in a horizontal state, and the two side plates are roughly in a vertical state.

[0008] When the compressor is assembled to the first shell, the first shell is usually in a lying state. When the compressor is assembled to the first shell, the mutual positioning of the limiting protrusion and the first limiting groove can prevent the compressor from tipping over (turning over) and will not affect the assembly of the second shell to the first shell.

[0009] Furthermore, the first shell is also provided with two limit ribs extending in the front-to-back direction, and the limit ribs are located between the two guide ribs; the limit ribs have a second limit groove, and the opening direction of the second limit groove is away from the first shell; the rear end of the main plate component of the shock-absorbing base is inserted into the second limit groove. The second limit groove can be provided to limit the limit position of the shock-absorbing base moving backward. Preferably, two limit ribs are provided.

[0010] Furthermore, the main body plate component of the shock-absorbing base is provided with ribs extending in the front-to-back direction below, and the ribs and the limiting ribs fit each other in the left-right direction. That is, the ribs and the limiting ribs fit each other and can also guide the movement of the shock-absorbing base, ensuring that the shock-absorbing base moves toward the first shell along the front-to-back direction during assembly.

[0011] Furthermore, a fixing plate is provided below the main body plate component, and a through hole is provided on the fixing plate; a screw hole is provided in the first shell corresponding to the through hole; and the fixing plate is fixed to the first shell by a fastener. After the shock absorbing base is inserted into the first shell, the shock absorbing base can be further fixed to the first shell by the fastener, thereby improving the reliability of assembly.

[0012] Furthermore, a second shell is included, the second shell is located in front of the first shell, and the shock-absorbing base is located between the first shell and the second shell; a third limiting groove is provided on the second shell, and the opening direction of the third limiting groove is away from the second shell; the front end of the main plate component of the shock-absorbing base is stuck in the third limiting groove. The third limiting groove can be provided to limit the limit position of the shock-absorbing base moving forward. Preferably, the second shell is a compressor cover. After the first shell and the second shell are assembled together, the compressor is confined in the compressor chamber formed by the first shell and the second shell, which helps to reduce noise.

[0013] Furthermore, the main body panel component, the side panels and the ribs are integrally formed. The shock-absorbing base is usually manufactured by integrally forming hard plastic to reduce assembly procedures.

[0014] Compared with the prior art, the utility model only needs to push the compressor assembly (including the compressor, the shock absorbing structure, and the shock absorbing base) into the corresponding first limiting groove and second limiting groove on the first shell of the oxygen concentrator during assembly, thereby simplifying the assembly process and improving production efficiency; it can also prevent the shock absorbing base from tipping over (turning over) during reassembly.

The shock-absorbing base 2 can be fixed to the first shell 1 by only pushing it toward the first shell 1.
