Elastic strips 105 are fixedly connected to the inner wall of the cavity 104 at equal intervals. An elastic sheet 102 is fixedly connected to the upper end of the surface of the connecting sleeve 101 at equal angles. The elastic deformation of the elastic sheet 102 is utilized to make it close to the inside of the pipeline, thereby ensuring the sealing between the connecting sleeve 101 and the inside of the pipeline.

[0038] Example 2

[0039] Based on Example 1, a preferred embodiment of the air filter cleaning tool with a sealing structure provided by the utility model is as follows: Figures 1 to 7 As shown: the clamping assembly 5 includes a fixing plate 504, which is fixedly connected to the top of the mounting plate 9 at an equal angle, and an electric push rod 501 is fixedly connected to one side of the fixing plate 504, the output end of the electric push rod 501 passes through the electric push rod 501 and is fixedly connected to a clamping plate 503, and a sponge plate 502 is fixedly connected to one side of the clamping plate 503. By starting the electric push rod 501 to drive the clamping plate 503 to slide, the sponge plate 502 can flexibly clamp and fix the air filter element, thereby achieving firm clamping and fixing of air filters of different specifications, which is convenient for subsequent cleaning actions.

[0040] In this embodiment, one side of the sponge board 502 is arc-shaped, and there are four sponge boards 502 distributed at equal angles. The use of four sponge boards 502 at equal angles facilitates multi-directional clamping and fixing of the air filter element.

[0041] In this embodiment, the rotating component 15 includes a servo motor 1501, which is fixedly connected to one end of the support seat 6, and an auxiliary ring groove 1502 is provided in a ring shape at the top of the support seat 6. Auxiliary blocks 1503 that slide with the auxiliary ring groove 1502 are fixedly connected around the bottom of the mounting plate 9. The mounting plate 9 is driven to rotate by starting the servo motor 1501, so that the mounting plate 9 can rotate smoothly during mold change, thereby realizing the full rotation of the air filter element and cooperating with the jet pipe 3 to realize a full cleaning action.

[0042] Furthermore, a dustproof seat 13 is fixedly connected to the upper end of one side of the inner wall of the shell 4, and a dustproof net 14 is fixedly connected to one side of the top of the dustproof seat 13 by bolts. The dustproof seat 13 and the dustproof net 14 are used to block dust and other impurities to prevent dust and other impurities blown out of the air filter from being discharged through the exhaust pipe 10.

[0043] In addition, guide plates 8 are fixedly connected to both sides of the inner bottom wall of the shell 4, and the guide plates 8 are inclined at an angle of forty degrees to the horizontal direction.

Then, the flanges of the two are locked and fixed by external bolts and nuts;

[0045] After that, the door body 16 is opened, and the air filter element is placed on the top of the installation plate 9. Then, the electric push rod 501 is started to drive the clamping plate 503 to slide, so that the sponge plate 502 can flexibly clamp and fix the air filter element, thereby realizing the firm clamping and fixing of air filters of different specifications, which is convenient for subsequent cleaning actions. Then, the pneumatic telescopic rod 11 is started to drive the jet pipe 3 to descend into the middle position of the air filter element, and the high-pressure air is sprayed out through the jet pipe 3 through the external high-pressure air pump and other blowing equipment, which is convenient for cleaning and dust removal of the air filter element, and the pneumatic telescopic rod 11 drives the jet pipe 3 to move up and down, and at the same time, the servo motor 1501 is started to drive the installation plate 9 to rotate, and the auxiliary block 1503 is used to slide inside the auxiliary ring groove 1502, so that the installation plate 9 can rotate smoothly during mold change, realize the comprehensive rotation of the air filter element and cooperate with the jet pipe 3 to realize the comprehensive cleaning action, thereby improving the comprehensive cleaning and dust removal effect of the air filter element.

[0046] At the same time, the excess air can be filtered through the dustproof net 14 and then discharged from the exhaust pipe 10 to prevent the air inside the shell 4 from increasing. After the air filter element is cleaned and dusted, the door body 16 is opened, the air filter element is taken out, and then the dust discharge door 12 is opened. The inclined guide plate 8 is used to guide the blown dust and other impurities so that they can be discharged more quickly through the dust discharge slot 7, thereby achieving the cleaning and discharge of dust and impurities.
