[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-pressure filter with a self-cleaning function, including an outer shell 1, an air outlet 2, a connecting cover 3, an air inlet 4, a motor 5, a bevel gear 6, a lead screw 7, a moving ring 8, a nozzle 9, a water pipe 10, a limiting groove 11, a sealing ring 12, a bolt 13, a filter element 14, and a filter screen 15.

[0029] Embodiment 1

[0030] The high-pressure filter with a self-cleaning function is provided with a cleaning structure, which can drive the nozzle 9 through the moving ring 8 to clean the filter element 14 and the filter screen 15. Specifically:

[0031] The lower surface of the outer shell 1 is connected with an air outlet 2, and further includes a connection cover 3. The upper surface of the outer shell 1 is threadedly connected with the connection cover 3, and the upper surface of the connection cover 3 is connected with an air inlet 4. The outer shell 1 is connected with a cleaning structure. The cleaning structure includes a motor 5. The motor 5 is installed on the side surface of the outer shell 1. A bevel gear 6 is installed on the outer surface of the rotating shaft of the motor 5. Another bevel gear 6 is meshed and connected below the bevel gear 6. This bevel gear 6 is fixedly installed on the outer surface of a lead screw 7. The lead screw 7 is rotatably installed on the bottom surface of the interlayer of the outer shell 1. A connecting piece is rotatably connected to the outer surface of the lead screw 7. A nozzle 9 is installed on the inner wall surface of the moving ring 8, and the nozzle 9 is connected through a water pipe 10. The other end of the water pipe 10 slidably penetrates through the outer surface of the outer shell 1. A limiting groove 11 corresponds to the lower part of the water pipe 10. The water pipe 10 is made of a flexible material. A plurality of nozzles 9 are arranged at equal intervals;

[0032] When the high-pressure filter with self-cleaning function filters air, first, the air enters the interior of the outer shell 1 through the air inlet 4, then the air will pass through the filter element 14 and the filter screen 15, and finally is discharged through the air outlet 2. After being used for a period of time, dust will adhere to the filter element 14 and the filter screen 15. As Figure 2 shown, at this time, the motor 5 is turned on, so that the motor 5 drives the bevel gear 6 on the outer surface of the rotating shaft to rotate. Since another bevel gear 6 is meshed and connected below the bevel gear 6, and this bevel gear 6 is fixedly installed on the outer surface of the lead screw 7, the lead screw 7 rotates, so that the connecting piece rotatably connected to the outer surface of the lead screw 7 moves downward. Since this connecting piece is fixedly connected to the moving ring 8, the moving ring 8 will be driven to move downward. At the same time, the nozzle 9 installed on the inner wall surface of the moving ring 8 is connected to the water pipe 10 and turned on, so that the nozzle 9 sprays high-pressure water flow to wash the filter screen 15. Then the moving ring 8 will make the water pipe 10 slide downward in the limiting groove 11, so that the moving ring 8 drives the nozzle 9 to wash the whole of the filter element 14 and the filter screen 15. When the motor 5 is turned on to rotate in the reverse direction, the lead screw 7 will be driven to rotate in the reverse direction, so that the moving ring 8 can move upward. In this way, the attached dust will be washed clean, and finally the water flow is discharged through the air outlet 2 at the lower end.

[0033] Embodiment 2

[0034] The high-pressure filter with self-cleaning function is also provided with a replacement structure. After the connection cover 3 is rotated and disassembled, the filter element 14 and the filter screen 15 can be directly replaced. Specifically:

[0035] The connection cover 3 is connected with a replacement structure. The replacement structure can replace the filter element 14 and the filter screen 15 by disassembling the connection cover 3. The replacement structure includes bolts 13. The bolts 13 are installed on the upper surface of the connection cover 3 at equal intervals. The lower surface of the connection cover 3 is threadedly connected with the filter element 14 and the filter screen 15. A sealing ring 12 is installed on the lower surface of the connection cover 3. The filter element 14 is inside the filter screen 15;

[0036] When the filter element 14 and the filter screen 15 reach their service life, they need to be replaced. First, the bolts 13 on the upper surface of the connecting cover 3 are disassembled in sequence. Then, the connecting cover 3 is rotated so that the connecting cover 3 is separated from the housing 1. Then, the filter element 14 and the filter screen 15 are taken out for replacement. Finally, the connecting cover 3 is reinstalled on the upper surface of the housing 1 through the bolts 13, and the sealing ring 12 can also make the connection more tight.

[0037] Working principle: When using the high-pressure filter with self-cleaning function, a cleaning structure is provided, which can make the moving ring 8 lift and lower inside the housing 1 through the lead screw 7, and at the same time drive the nozzle 9 to clean the filter screen 15. The replacement structure can quickly replace the filter element 14 and the filter screen 15, increasing the overall practicability.

[0038] Although the embodiments of the present invention 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 invention.
