Description

Technical Field

[0001] This utility model relates to the technical field of oxygen generator vibration damping equipment, and more specifically to an oxygen generator compressor vibration damping device and an oxygen generator compressor. Background Technology

[0002] An oxygen concentrator is a device that uses pressure swing adsorption (PSA) technology to extract oxygen from the air. When an oxygen concentrator is working, it needs to change the air pressure via a compressor. The compressor generates vibrations during operation, which can damage the oxygen concentrator and produce significant noise. While existing compressor vibration damping devices can meet the requirements for stationary use in general residential oxygen concentrators, they are insufficient for the demands of vehicle-mounted use with strong impact and vibration. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to meet the shock absorption requirements of the strong impact vibration of the vehicle-mounted oxygen generator compressor.

[0004] This utility model solves the above-mentioned technical problems through the following technical means: an oxygen concentrator compressor vibration damping device, including a compressor vibration damping spring, a nylon seat, a primary rubber vibration damping pad, a flat washer, a spring washer, a mounting base, and mounting bolts. The mounting base is connected to the compressor through the compressor vibration damping spring. One end of the screw of the mounting bolt is fixed to the compressor, and the other end is slidably engaged with the mounting base, with the head of the mounting bolt abutting against the mounting base. The screw is also sequentially fitted with a nylon seat, a primary rubber vibration damping pad, a spring washer, and a flat washer. The mounting base abuts against the compressor through the primary rubber vibration damping pad, the flat washer, the spring washer, and the nylon seat.

[0005] By using a nylon seat, spring washers, flat washers, and primary rubber damping pads, a fully contact elastic connection structure is formed between the compressor base and the mounting base. While ensuring the damping effect in conjunction with the compressor damping spring, it can withstand strong impact vibrations during vehicle use, thus improving the overall durability of the damping device.

[0006] As a preferred technical solution, the primary rubber damping pad abuts against the head of the mounting bolt via a secondary rubber pad, and the secondary rubber pad is snapped and fixed to the mounting base.

[0007] As a preferred technical solution, the secondary rubber pad has an installation hole adapted to the screw, the secondary rubber pad has an annular installation groove in its circumference and is connected to the mounting base through the annular installation groove, and the mounting base has a hole adapted to the secondary rubber pad.

[0008] As a preferred technical solution, one end of the nylon seat abuts against the compressor, and the other end is provided with a spring mounting step, which is elastically connected to the compressor's shock-absorbing spring through the mounting step.

[0009] As a preferred technical solution, the primary rubber shock-absorbing pad has a pad mounting step at one end facing the nylon seat, and the spring washer and flat washer are coaxially arranged and sequentially arranged in the pad mounting step.

[0010] As a preferred technical solution, the nylon seat is fastened to the gasket mounting step, causing the spring washer to compress.

[0011] As a preferred technical solution, the compressor shock-absorbing spring, nylon seat, primary rubber shock-absorbing pad, flat washer, spring washer, and mounting bolt are coaxially arranged.

[0012] As a preferred technical solution, the compressor damping spring is located outside the primary rubber damping pad.

[0013] As a preferred technical solution, the system also includes a compressor base, wherein the screw end of the mounting bolt is threadedly connected to the compressor base.

[0014] An oxygen generator compressor includes the aforementioned oxygen generator compressor vibration damping device.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) In this utility model, by setting up a nylon seat, spring washer, flat washer and primary rubber shock absorber, a fully contact elastic connection structure is formed between the compressor base and the mounting base. Under the premise of ensuring the shock absorption effect in conjunction with the compressor shock absorber spring, it can cope with strong impact vibration when used in a vehicle and improve the durability of the entire shock absorber.

[0017] (2) In this utility model, the compressor base and the mounting base can be pre-tightened by the spring washer and the flat washer. When the mounting bolt and the compressor base are moved due to impact vibration, the nylon seat, spring washer, flat washer, primary rubber shock absorber and secondary rubber pad can still be in a resisting state to ensure shock absorption performance.
