Description

Technical Field

[0001] This utility model specifically relates to the field of compressor vibration reduction and noise reduction technology, and specifically to a compressor vibration reduction and noise reduction device for an oxygen generator. Background Technology

[0002] An oxygen concentrator is a machine that produces oxygen using air separation technology or chemical reactions. It utilizes molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves, which are mainly composed of materials with precise and single micropores. The interior is filled with silicates or aluminosilicates. When pressurized, the molecular sieve can adsorb nitrogen in the air, and the unabsorbed oxygen is collected. After purification, high-purity oxygen is obtained. When depressurized, the molecular sieve releases the adsorbed nitrogen back into the ambient air. When pressurized again, it can adsorb nitrogen and produce oxygen again.

[0003] Before oxygen production, the air needs to be compressed using an internal compressor. When the compressor is working, the internal mechanical movement will cause vibration, which will be transmitted to the support frame, and noise will also be generated during the vibration.

[0004] However, in practice, it has been noted that most current vibration and noise reduction methods use sound insulation pads to wrap the compressor. This noise reduction method affects the normal heat dissipation of the compressor. Furthermore, since the compressor is wrapped with sound insulation pads, the pads need to be removed during compressor maintenance. The gap between the compressor and the support frame is small, making removal difficult and time-consuming. In addition, the compressor and the support frame are still rigidly connected, so vibrations are still transmitted to the support frame, resulting in poor vibration reduction effect. Utility Model Content

[0005] The purpose of this invention is to provide a vibration damping and noise reduction device for an oxygen concentrator compressor. This device utilizes a rubber suction pad at the bottom of the compressor to reduce vibration and noise, and a fixed track and vibration damping bracket are provided between the compressor and the outer frame to facilitate compressor removal and maintenance. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A compressor vibration damping and noise reduction device for an oxygen concentrator includes an outer frame, a compressor is provided at the bottom inner side of the outer frame, and a fixed track and a vibration damping bracket are provided between the compressor and the outer frame.

[0008] The bottom of the fixed track is fixedly connected to the outer frame, and the bottom of the compressor is fixedly connected to the shock-absorbing bracket.

[0009] As a further technical solution of this utility model, the shock-absorbing bracket includes a mounting plate fixedly connected to the bottom of the compressor, and a rubber suction pad is provided between the mounting plate and the compressor. The bottom of the compressor is provided with fixing bolts, and the fixing bolts pass through the mounting plate and the rubber suction pad respectively.

[0010] As a further technical solution of this utility model, the bottom of the mounting plate is fixedly connected to a fixed slide rail corresponding to the fixed track. Each fixed track includes a dovetail groove slide rail, and an intermediate support frame is inserted into the dovetail groove slide rail, and the intermediate support frame is movably connected to the fixed slide rail.

[0011] As a further technical solution of this utility model, the intermediate support frame has two symmetrically arranged dovetail-shaped rails and a horizontal plate integrally arranged in the middle. The two dovetail-shaped rails are slidably connected to the dovetail groove slide rail and the fixed slide rail respectively, and the horizontal plate is located between the dovetail groove slide rail and the fixed slide rail.

[0012] As a further technical solution of this utility model, the dovetail groove slide rail is provided with an end baffle at the far end, and a positioning slot is provided at the position of the outer frame between the two dovetail groove slide rails.

[0013] As a further technical solution of this utility model, the bottom of the mounting plate is fixedly connected to an internal threaded tube, the bottom of the internal threaded tube is connected to a limiting rod, and the end of the limiting rod is inserted into a positioning slot. The outer side of the limiting rod is integrally provided with a hexagonal clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

The mounting plate also includes a fixed slide rail, a dovetail slide rail, and a central support frame underneath, with the central support frame slidingly engaging with both the fixed and dovetail slide rails. This facilitates pulling the mounting plate out from the inside of the outer frame, allowing for easy removal of the compressor for maintenance. Furthermore, a threaded connection between the internal threaded tube and the limiting rod allows the limiting rod to move up and down below the mounting plate. The insertion and engagement between the limiting rod and the positioning slot secures the mounting plate within the outer frame. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See also Figure 1-9 This utility model provides a compressor vibration reduction and noise reduction device for an oxygen concentrator, including an outer frame 1, a compressor 8 is provided on the inner bottom of the outer frame 1, and a fixed track 6 and a vibration reduction bracket 7 are provided between the compressor 8 and the outer frame 1. The fixed track 6 is symmetrically arranged below the vibration reduction bracket 7, and the fixed track 6 and the vibration reduction bracket 7 are movably connected.

[0029] The bottom of the fixed track 6 is fixedly connected to the outer frame 1, and the bottom of the compressor 8 is fixedly connected to the shock-absorbing bracket 7. The sliding connection between the fixed track 6 and the shock-absorbing bracket 7 facilitates the quick removal of the compressor 8 from the outer frame 1 for maintenance.

[0030] In this embodiment, the shock-absorbing bracket 7 includes a mounting plate 71 fixedly connected to the bottom of the compressor 8, and a rubber suction pad 72 is provided between the mounting plate 71 and the compressor 8. The bottom of the compressor 8 is provided with fixing bolts, and the fixing bolts pass through the mounting plate 71 and the rubber suction pad 72 respectively.

[0031] Furthermore, the bottom of the mounting plate 71 is fixedly connected to a fixed slide rail 73 corresponding to the fixed track 6. Each fixed track 6 includes a dovetail slide rail 61, on which an intermediate support frame 63 is inserted, and the intermediate support frame 63 is movably connected to the fixed slide rail 73.

[0032] Furthermore, the intermediate support frame 63 has two symmetrically arranged dovetail-shaped rails and a horizontal plate integrally arranged in the middle. The two dovetail-shaped rails are slidably connected to the dovetail groove slide rail 61 and the fixed slide rail 73 respectively, and the horizontal plate is located between the dovetail groove slide rail 61 and the fixed slide rail 73.

[0033] More specifically, the dovetail slide rail 61 has an end baffle 62 integrally provided at the far end, and a positioning slot 9 is provided at the position of the outer frame 1 between the two dovetail slide rails 61.

[0034] In this embodiment, the bottom of the mounting plate 71 is fixedly connected to an internally threaded tube 74, the bottom of the internally threaded tube 74 is connected to a limiting rod 75, and the end of the limiting rod 75 is inserted into the positioning slot 9. The outer side of the limiting rod 75 is integrally provided with a hexagonal clamping plate 76.

[0035] By adopting the above technical solution, a shock-absorbing rubber suction pad 72 is placed at the bottom of the compressor 8. The rubber suction pad 72 absorbs the vibration of the compressor 8 during use, thereby reducing noise by reducing vibration. Furthermore, by pulling the mounting plate 71 forward, the mounting plate 71 moves the compressor 8 out of the outer frame 1 through the sliding cooperation between the fixed slide rail 73, the intermediate support frame 63, and the dovetail groove slide rail 61, making it easier to maintain the compressor 8.

[0036] In this embodiment, a molecular sieve adsorption tower 2 is also fixedly connected to the outer frame 1. The compressor 8 is fixedly connected to the inlet of the molecular sieve adsorption tower 2 through a hose. The compressed air enters the molecular sieve adsorption tower 2, and the oxygen in the air is separated by the sieve in the molecular sieve adsorption tower 2.

[0037] Furthermore, the outlet of the molecular sieve adsorption tower 2 is fixedly connected to the inlet of the oxygen storage tank 3, and the outlet of the oxygen storage tank 3 is fixedly connected to the oxygen humidification bottle 4 via a flexible hose.

[0038] In this embodiment, a cooling fan 5 is also fixedly connected to the outer frame 1. There are two cooling fans 5, one of which is located above the compressor 8 and the other is located on the side of the oxygen humidification bottle 4, which improves the heat dissipation effect of the oxygen generator.

[0039] In this embodiment, the limiting top rod 75 is integrally provided with an external thread on the side near the internal threaded tube 74, and the limiting top rod 75 and the internal threaded tube 74 are threadedly connected, and the hexagonal clamping plate 76 is located above the positioning groove 9.

[0040] The working principle of this invention is as follows: During use, the compressor 8 draws in outside air, compresses it, and sends the compressed air into the molecular sieve adsorption tower 2. The molecular sieve adsorption tower 2 separates oxygen from other gases in the air. After passing through the molecular sieve adsorption tower 2, the oxygen enters the oxygen storage tank 3 for storage. The oxygen in the oxygen storage tank 3 is then sent through a pipeline to the oxygen humidification bottle 4, where it is humidified by water. The vibration generated by the compressor 8 during operation is absorbed by the rubber suction pad 72 at the bottom, thereby reducing the vibration of the compressor. 8. To reduce the noise generated during vibration, the compressor 8 is maintained by rotating the limiting rod 75 through the hexagonal clamp 76. Through the threaded engagement between the limiting rod 75 and the internal threaded tube 74, the limiting rod 75 moves upward until the end of the limiting rod 75 separates from the positioning slot 9. Then, the mounting plate 71 is pulled forward. Through the sliding engagement of the fixed slide rail 73, the intermediate support frame 63, and the dovetail slide rail 61, the mounting plate 71 drives the compressor 8 to slide out from the inside of the outer frame 1, facilitating the maintenance of the compressor 8.
