Description

Technical Field

[0001] The present application relates to the technical field of filtering mechanisms, and specifically to a medical oxygen generator with an air filtering mechanism. Background Art

[0002] A medical oxygen generator is a new type of device that extracts oxygen from the air based on pressure swing adsorption technology. It uses molecular sieve physical adsorption and desorption technology to fill molecular sieves in the oxygen generator. When pressurized, nitrogen in the air can be adsorbed, and the remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification treatment. However, there are still certain problems and defects in existing medical oxygen generators. The specific problems are as follows: Existing medical oxygen generators do not have a filtering device, which affects the purity of oxygen during the oxygen generation process. Even if some oxygen generators are equipped with a filtering mechanism, due to the long-term operation of the filtering mechanism, the filter mesh plate needs to be replaced in a timely manner. The existing device is not convenient for quickly replacing the filter mesh plate. Therefore, we propose a medical oxygen generator with an air filtering mechanism to solve the above-mentioned problems. Utility Model Content

[0005] (2) Technical Solutions

[0006] To achieve the above object, the present application provides the following technical solution: A medical oxygen generator with an air filtering mechanism includes an oxygen generator body. A through hole is opened at the top of the oxygen generator body, and a bracket is slidably and rotatably installed on the through hole. A fixing groove is opened at the bottom end of the bracket, and a filter mesh plate is clamped on the fixing groove. Two limiting plates are fixedly installed in the top area of the inner side wall of the oxygen generator body, and the top end of each limiting plate is clamped and fitted with the bottom end of the filter mesh plate. A limiting groove is opened at the top of the oxygen generator body, and a sliding plate is slidably and rotatably installed on the limiting groove. One end of the sliding plate is slidably connected to the outer side wall of the bracket, and the other end of the sliding plate is fixedly installed with a rotating rod. Both ends of the rotating rod are rotatably installed on the outer side wall of the oxygen generator body through rotation;

[0007] The rotating mechanism includes a fixing block fixedly installed on the outer side wall of the oxygen generator body. A connecting groove is opened on the outer side wall of the fixing block, and the rotating rod is located inside the connecting groove and rotatably connected to the connecting groove. A top plate is attached to the outer side wall of each fixing block, and the top plate is installed on the outer side wall of the oxygen generator body through a sliding mechanism.

[0008] Preferably, the sliding mechanism includes a column which is fixedly installed on the outer side wall of the oxygen generator body. A first sliding groove is formed on the outer side wall of the top plate, and a second sliding groove is formed on the outer side wall of the column. Two sliders are symmetrically and slidably installed on the second sliding groove, and the two sliders are fixedly installed on the outer side wall of the top plate in parallel.

[0021] Embodiment

[0022] Please refer to Figures 1-4 , a medical oxygen generator with an air filtering mechanism, including an oxygen generator body 1. A through hole 2 is opened at the top end of the oxygen generator body 1. A bracket 3 is slidably and rotatably installed on the through hole 2. A fixing groove 4 is opened at the bottom end of the bracket 3. A filter mesh plate 5 is clamped on the fixing groove 4. Two limiting plates 6 are fixedly installed in the top area of the inner side wall of the oxygen generator body 1. The top end of each limiting plate 6 is clamped and attached to the bottom end of the filter mesh plate 5. A limiting groove 7 is opened at the top end of the oxygen generator body 1. A sliding plate 8 is slidably and rotatably installed on the limiting groove 7. One end of the sliding plate 8 is slidably connected to the outer side wall of the bracket 3. The other end of the sliding plate 8 is fixedly installed with a rotating rod 9. Both ends of the rotating rod 9 are rotatably installed on the outer side wall of the oxygen generator body 1 through rotation; the sliding mechanism includes a column 14. The column 14 is fixedly installed on the outer side wall of the oxygen generator body 1. A first chute 13 is opened on the outer side wall of the top plate 12. A second chute 15 is opened on the outer side wall of the column 14. Two sliders 16 are symmetrically and slidably installed on the second chute 15. The two sliders 16 are fixedly installed in parallel on the outer side wall of the top plate 12. By sliding the sliders 16 fixed on the top plate 12 inside the second chute 15 opened on the column 14, the height adjustment operation of the top plate 12 is facilitated. A rotating shaft 17 is rotatably installed at the top end of the oxygen generator body 1. The top end of the rotating shaft 17 is fixedly installed with a rotating plate 18. The rotating plate 18 is attached to the top end of the bracket 3. Through the installation of the rotating shaft 17 and the rotating plate 18, the top end of the bracket 3 is limited.

[0023] Please refer to Figures 1-4, the rotating mechanism includes a fixed block 10 which is fixedly installed on the outer wall of the oxygen generator body 1. A connecting groove 11 is formed on the outer wall of the fixed block 10. The rotating rod 9 is located inside the connecting groove 11 and is rotatably connected to the connecting groove 11. A top plate 12 is attached to the outer wall of each fixed block 10. The top plate 12 is installed on the outer wall of the oxygen generator body 1 through a sliding mechanism. For this medical oxygen generator with an air filtering mechanism, the oxygen generator body 1 is filtered by the filter mesh plate 5. The filter mesh plate 5 is clamped through the fixing groove 4 formed on the bracket 3. Through the cooperation of the sliding plate 8 and the rotating rod 9, the bracket 3 is stably fixed inside the oxygen generator body 1. By the contact between the top plate 12 and the fixed block 10, the rotating rod 9 is prevented from disengaging from the connecting groove 11 formed on the fixed block 10, thus completing the rapid installation of the filter mesh plate 5. When the filter mesh plate 5 needs to be replaced, the above operation process is reversed, which facilitates the rapid installation and disassembly of the filter mesh plate 5 by the device, improving the practicability.

[0024] Please refer to Figure 1 , it should also be noted that a plurality of handles 19 are symmetrically and fixedly installed on the outer wall of the oxygen generator body 1. By installing the handles 19, it is convenient for the user to move the device.

[0025] Please refer to Figure 1 , a plurality of support columns 20 are fixedly installed around the bottom end of the oxygen generator body 1. By installing the support columns 20, it is convenient to support the device.

[0026] In summary, when this medical oxygen generator with an air filtering mechanism is in use, the device is moved to the working area through the handle 19, and the device is supported through the support columns 20. When the filter mesh plate 5 needs to be replaced, the vertical height of the top plate 12 is adjusted, so that the first sliding groove 13 formed on the top plate 12 is aligned with the outer wall of the connecting groove 11. The rotating rod 9 drives the sliding plate 8 to slide with the bracket 3, so that the rotating rod 9 disengages from the connecting groove 11 and the first sliding groove 13 formed on the top plate 12. The rotating plate 18 is rotated, so that the rotating plate 18 disengages from the bracket 3. After the height of the bracket 3 is lifted, the filter mesh plate 5 is disengaged from the fixing groove 4 formed at the bottom end of the bracket 3. Then the replaced filter mesh plate 5 is reinstalled at the bottom end of the bracket 3, thus completing the rapid replacement operation of the filter mesh plate 5.

[0027] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
