[0028] Please refer to Figures 1 to 4 The utility model embodiment provides a kind of oxygen equipment high-efficiency heat dissipation auxiliary mechanism, oxygen equipment high-efficiency heat dissipation auxiliary mechanism includes:

[0029] Mounting frame 1 is fixed on oxygen generator, and fan 4 is fixed on mounting frame 1;

[0030] Filter structure 2 is detachably connected on mounting frame 1, and filter structure 2 includes plate filter screen 21 and cylinder filter screen 23, and the filter hole of cylinder filter screen 23 is smaller than the filter hole of plate filter screen 21;

[0031] Auxiliary cleaning piece 3 is installed on filter structure 2, and includes brush plate 36 in contact with cylinder filter screen 23.

[0032] It should be noted that this device is an air-cooled heat dissipation structure in the oxygen generator. The operation of fan 4 can accelerate air circulation and achieve heat dissipation for the oxygen generator.

[0033] The filter structure 2 includes a plate filter 21 and a cylindrical filter 23. The pore size of the plate filter 21 is larger than that of the cylindrical filter 23. Therefore, they are used to intercept dirt of different particle sizes, realize multi-level filtration, and improve the filtration effect.

[0034] The plate filter 21 is equivalent to the traditional single-layer filter structure, so the staff can clean it directly. The auxiliary cleaning component 3 is set for the cylindrical filter 23. The auxiliary cleaning component 3 can brush off the dirt intercepted on the cylindrical filter 23, thus cleaning the cylindrical filter 23. Therefore, when cleaning the entire filter structure 2, it is not necessary to disassemble it, which improves the convenience of use.

[0035] In the embodiments of this utility model, please refer to Figure 2 The mounting frame 1 includes a U-shaped mounting plate 11, which is fixed to the oxygen concentrator with screws. A housing 12 is integrally connected to one side of the mounting frame 1. The housing 12 extends from the heat dissipation vent of the oxygen concentrator into the interior of the oxygen concentrator. A connecting mounting cylinder 13 is fixed at the other end of the housing 12. An air duct is formed inside the housing 12 and the mounting cylinder 13. A fan 4 is fixed to the other end of the mounting cylinder 13.

[0036] The cover 12 is in the shape of a protrusion, and the horizontal height of the inner bottom of the cover 12 decreases from one end inside the oxygen generator to the end at the heat dissipation vent.

[0037] It should be noted that: for mounting bracket 1, its cover 12 is connected to mounting cylinder 13, and fan 4 is installed at the other end of mounting cylinder 13. When fan 4 is running, airflow passes through cover 12 and mounting cylinder 13, and then enters the oxygen generator.

[0038] In the embodiments of this utility model, please refer to Figure 3 The plate filter screen 21 is fixed to the mounting bracket 1 with screws. A solid plate 22 is integrally connected to the center of the plate filter screen 21. One end of the cylindrical filter screen 23 is fixed to the solid plate 22. The other end of the cylindrical filter screen 23 is pressed against the inner wall of the housing 12 through the sealing gasket 24 and covers the opening connecting the housing 12 and the mounting cylinder 13.

[0039] The plate filter screen 21 has a waste discharge port 25 near the bottom, which corresponds to the lowest point inside the housing 12. A rubber strip 26 that seals the waste discharge port 25 is also magnetically fixed on the plate filter screen 21.

[0040] It should be noted that: one end of the cylindrical filter screen 23 is closed by the solid plate 22. After the airflow passes through the plate filter screen 21, it needs to pass through the circumferential side wall of the cylindrical filter screen 23 and then enter the interior of the mounting cylinder 13 to achieve comprehensive filtration of the airflow.

[0041] The cartridge filter 23 is located inside the housing 12, so the dirt cleaned from the cartridge filter 23 will fall into the bottom of the housing 12. The bottom of the housing 12 is sloped, so that the dirt can fall down the slope and eventually be discharged from the waste outlet 25.

[0042] In the embodiments of this utility model, please refer to Figure 4 The auxiliary cleaning component 3 also includes a rotating shaft 31, which is rotatably connected to the solid plate 22. One end of the rotating shaft 31 is fixed with a handle 32, and the other end is fixed with a gear 33.

[0043] A toothed ring 34 and a positioning ring 35 are rotatably connected to the outside of the cylindrical filter screen 23. The brush plate 36 is fixed between the toothed ring 34 and the positioning ring 35, and the toothed ring 34 and the gear 33 mesh and drive each other.

[0044] It should be noted that when the auxiliary cleaning component 3 is in use, rotating the handle 32 drives the gear 33 to rotate through the shaft 31. The gear 33 meshes with the gear ring 34, which in turn drives the brush plate 36 to rotate through the gear ring 34. The brush plate 36 contacts the cylindrical filter screen 23 and can clean the cylindrical filter screen 23 during the rotation.

[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0046] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
