Description

Technical Field

[0001] This utility model relates to the field of vibration damping devices for compressors in oxygen concentrators, specifically a semi-suspended vibration damping device for compressors in portable oxygen concentrators. Background Technology

[0002] The compressor of an oxygen concentrator is the core power component, responsible for compressing air to supply oxygen to the subsequent molecular sieve separation. Its operation is inevitably accompanied by a certain amount of vibration, including normal vibration and abnormal vibration. Abnormal vibration is often noisy, has a large amplitude, and is unstable. It is mostly caused by component failure, improper installation, or environmental problems. Although normal vibration is unavoidable due to the compressor's own structure, over time, internal connections or other components will still loosen and will still develop into abnormal vibration. It's just a matter of how long it takes. How to extend the service life of the oxygen concentrator and delay the occurrence of abnormal vibration is a problem that needs to be solved. Some people add vibration damping pads under the oxygen concentrator or at the compressor connection, but the vibration spreads in all directions. This method can only solve unidirectional vibration. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a semi-suspended shock absorption device for the compressor in a portable oxygen concentrator, thereby solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A semi-suspended vibration damping device for a compressor in a portable oxygen concentrator includes a base, a vibration damping pad, a pressure plate, a compressor body, a connector, and a motor cover. The pressure plate is fixed to the base, and a vibration damping pad is sandwiched between the pressure plate and the base. The vibration damping pad extends from the pressure plate to the bottom of the compressor body. One end of the connector is connected to the compressor body, and the other end is suspended and fastened to the motor cover. The connector has wave-shaped elastic clips on both sides, which extend to the motor cover. The vibration damping pad and connector work together to reduce vibration in the compressor body, resulting in a semi-suspended state. The vibration damping pad reduces vertical vibration of the compressor body, while the wave-shaped elastic clips of the connector further absorb vibration in all directions around the compressor body, extending the service life of the oxygen concentrator and delaying abnormal vibrations caused by loose components, thus reducing overall vibration from multiple angles.

[0006] Preferably, the shock-absorbing pad is trumpet-shaped.

[0007] Preferably, the shock-absorbing pad has a connecting groove inside, and bolts are installed in the connecting groove to connect with the compressor body.

[0008] Compared to existing technologies, this utility model discloses a semi-suspended shock absorption device for the compressor in a portable oxygen concentrator, including a base, shock-absorbing pads, a pressure plate, a compressor body, a connector, and a motor cover. These six components work together to address the vibration of the compressor body. The shock-absorbing pads and connectors work together to make the compressor body semi-suspended. The shock-absorbing pads reduce the vertical vibration of the compressor body, while the wave-shaped elastic buckle of the connector further absorbs the vibration in the circumferential direction of the compressor body, extending the service life of the oxygen concentrator and delaying the occurrence of abnormal vibrations caused by loose components. This comprehensively reduces overall vibration. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] A semi-suspended shock absorption device for a compressor in a portable oxygen concentrator includes a base 1, a shock-absorbing pad 2, a pressure plate 3, a compressor body 4, a connector 5, and a motor cover 6. The pressure plate 3 is fixed to the base 1, and the shock-absorbing pad 2 is sandwiched between the pressure plate 3 and the base 1. The pressure plate 3 and the base 1 press the shock-absorbing pad 2 tightly. The shock-absorbing pad 2 extends from the pressure plate 3 and connects to the bottom of the compressor body 4. One end of the connector 5 is connected to the compressor body 4, and the other end is suspended and fastened to the motor cover 6. The connector 5 has wave-shaped elastic buckles 51 on both sides, and the wave-shaped elastic buckles 51 extend to the motor cover 6. The shape and structure of the wave-shaped elastic buckles 51, combined with the fact that the compressor body 4 is connected to the base 1 through the shock-absorbing pad 2 and is in a semi-suspended state, does not directly contact the base 1, so the wave-shaped elastic buckles 51 can absorb vibrations in all directions around the compressor body 4.

[0016] The shock-absorbing pad 2 is horn-shaped, and the material of the shock-absorbing pad 2 can be selected according to the actual situation. Generally, a buffer and shock-absorbing silicone material is used. Similarly, the wave-shaped elastic buckle 51 is also determined according to the actual situation. In this solution, the wave-shaped elastic buckle 51 is made of silicone material. The horn-shaped shock-absorbing pad 2 can reduce the vibration of the compressor body 4 in the vertical direction. The shock-absorbing pad 2 has a connecting groove 21 inside, and bolts are installed in the connecting groove 21 to connect with the compressor body 4.
