[0002] When the existing portable oxygen generator is working, the air compressor therein compresses air so as to separate nitrogen therefrom subsequently, thereby facilitating the subsequent oxygen generation process. When the air compressor compresses air, it will generate high-frequency vibration phenomena in the horizontal and vertical directions, thereby driving the components (such as the base) connected to the air compressor to vibrate and generate noise. The existing solution is generally to add springs between the air compressor and the base, but its shock-absorbing effect on the horizontal vibration is poor.

[0026] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 4 shown, a portable oxygen generator in an embodiment of the present utility model includes a fixed seat 3, an air compressor 2, and a shock absorption mechanism 1 of the portable oxygen generator connected between the fixed seat 3 and the air compressor 2 (for the convenience of description, hereinafter, the shock absorption mechanism 1 of the portable oxygen generator will be simply referred to as the shock absorption mechanism 1); wherein the shock absorption mechanism 1 includes a shock absorber 11, and the shock absorber 11 includes a first connection part 111, a second connection part 112 sleeved outside the first connection part 111, and an elastic shock absorption part 113 extending outward and bent from the first connection part 111 and connected to the second connection part 112. The first connection part 111 can be connected to the air compressor 2 in the oxygen generator, and the second connection part 112 can be connected to the fixed seat 3 in the oxygen generator.

[0028] It can be understood that, in the present utility model, the elastic shock-absorbing part 113 of the second connecting part 112 that is bent to connect the first connecting part 111 in the shock-absorbing part 11, that is, the elastic shock-absorbing part 113 has a "U" - shaped structure, and can achieve good shock-absorbing effects in both the horizontal and vertical directions. Furthermore, the shock-absorbing mechanism 1 of the present utility model effectively absorbs and eliminates the vibrations transmitted from the air compressor 2 of the portable oxygen generator to the base, enabling the portable oxygen generator to operate more stably, quietly, and durably.

[0029] Preferably, the materials of the first connecting part 111, the second connecting part 112, and the elastic shock-absorbing part 113 can all be elastic rubber materials that can be purchased on the market, thereby achieving good shock-absorbing effects.

[0030] The first connecting part 111 is columnar or tubular. One end of the first connecting part 111 in the axial direction is connected to the elastic shock-absorbing part 113, and the other end can be connected to the air compressor 2 in the oxygen generator; such a design is to prevent the air compressor 2 from directly contacting the second connecting part 112 during vibration, enabling the elastic shock-absorbing part 113 to fully absorb and eliminate the vibrations transmitted by the air compressor 2. Specifically, in this embodiment, the first connecting part 111 is tubular, and the first connecting part 111 is made of elastic rubber material, so as to achieve shock-absorbing effects in the horizontal direction (i.e., the radial direction of the first connecting part 111).

[0031] As Figure 3 and 4 shown, the second connecting part 112 has a second connecting hole 115 inside, and a part of the first connecting part 111 is arranged inside the second connecting hole 115; an elastic support rib 116 is connected between the outer peripheral surface of the first connecting part 111 in its axial direction and the inner wall of the second connecting hole 115. The elastic support rib 116 can not only enhance the connection strength between the first connecting part 111 and the second connecting part 112, but also achieve shock-absorbing effects in the horizontal direction. Specifically, the material of the elastic support rib 116 can be an elastic rubber material that can be purchased on the market.

[0032] Furthermore, a plurality of elastic support ribs 116 are equidistantly spaced between the outer peripheral surface of the first connecting part 111 and the inner wall of the second connecting hole 115. The plurality of equidistantly spaced elastic support ribs 116 can achieve uniform shock-absorbing effects in the horizontal direction.

[0033] Furthermore, the elastic support rib 116 is connected to the elastic shock-absorbing part 113. Such a setting can improve the shock-absorbing effect of the elastic shock-absorbing part 113 (i.e., improve the stability of the elastic shock-absorbing part 113 during the shock-absorbing process) and the connection strength of the elastic shock-absorbing part 113.

[0034] As Figure 1 、 3As shown in FIGS. 3 and 4, a first connection hole 114 is provided on the first connection part 111, and the first connection hole 114 can be connected to the air compressor 2 in the oxygen generator. That is, the shock absorber 11 is connected to the bottom of the air compressor 2 through the first connection hole 114, and the connection method can be plug connection, interference fit, bonding, screw connection, etc.

[0035] Furthermore, a first mounting ring 12 is fixedly connected to one end of the first connection hole 114 away from the elastic shock-absorbing part 113, and the first mounting ring 12 can be threadedly connected to the air compressor 2. Since the first connection part 111 can be made of elastic rubber material, the connection strength of plug connection, interference fit, etc. may not be sufficient. Therefore, the first mounting ring 12 can be bonded in the first connection hole 114, and the first mounting ring 12 is threadedly connected to the bottom of the air compressor 2, thereby improving the connection stability between the shock absorber 11 and the air compressor 2; in addition, once the shock absorber 11 needs to be replaced, it is also convenient for the disassembly and installation of the shock absorber 11 and the air compressor 2.

[0036] As Figure 1 、 3 As shown in FIGS. 3 and 4, the second connection part 112 is annular, and a second mounting ring 13 is installed on the outer peripheral surface of the second connection part 112, and the second mounting ring 13 can be in interference fit with the fixing hole on the fixing seat 3. Such a setting plays a role in stably connecting the shock absorber 11 and the fixing seat 3. Preferably, the second mounting ring 13 and the second connection part 112 can be bonded, and the connection effect is better.

[0037] The first mounting ring 12 and the second mounting ring 13 can both be metal rings.

[0038] Preferably, in this embodiment, the first connection part 111, the second connection part 112, and the elastic shock-absorbing part 113 are integrally formed, and the shock absorber 11 is a shock absorber 11 made of rubber material. Thereby, the stability, shock-absorbing effect, and connection strength between various parts of the shock absorber 11 can be improved.

[0039] Compared with the prior art, the shock-absorbing mechanism 1 of the portable oxygen generator and the portable oxygen generator of the present invention can achieve good shock-absorbing effects in both the horizontal and vertical directions through the elastic shock-absorbing part 113 of the second connection part 112 that is bent and connected to the first connection part 111 in the shock absorber 11. That is, the shock-absorbing mechanism 1 of the present invention effectively absorbs and eliminates the vibration transmitted from the air compressor 2 of the portable oxygen generator to the base during operation, so that the portable oxygen generator can operate more stably, quietly, and durably.
