[0039] A filter plate 21 is detachably mounted on the top of the guide frame 16. The filter plate 21 can be fixed on the guide frame 16 using bolts.

[0040] A driving assembly is disposed on the top of the tank air filter body 1 , and the driving assembly drives the fixed shaft 10 located above the filter plate 21 to slide back and forth horizontally.

[0041] There are two drive assemblies, which are symmetrically arranged on the top of the tank air filter body 1, and the filter plate 21 is located between the two drive assemblies.

[0042] The driving assembly includes a first threaded rod 4. Two fixed blocks 2 are symmetrically fixedly connected to the top of the liquid tank air filter body 1, and a motor 3 is fixedly connected to one side of each fixed block 2.

[0043] Both ends of the fixed shaft 10 are coaxially fixedly connected with a second threaded rod 6, and the second threaded rod 6 is perpendicular to the first threaded rod 4. The threads of the second threaded rod 6 respectively penetrate the moving block 5. When the second threaded rod 6 rotates in the moving block 5, the second threaded rod 6 will also move on the moving block 5.

[0044] A cleaning brush 11 and a fixing plate 22 are fixedly connected to the outer surface of the fixing shaft 10, and the fixing plate 22 and the cleaning brush 11 are distributed along the same axis of the fixing shaft 10.

[0045] The bottom surface of the fixed plate 22 is fixedly connected with a plurality of telescopic rods 14 at intervals, the connecting rod 13 is fixedly connected to the bottom ends of the plurality of telescopic rods 14, and a plurality of hemispherical knocking blocks are fixedly connected with a surface of the connecting rod 13 away from the telescopic rod 14 at intervals.

[0046] The telescopic rod 14 is composed of a sleeve and a sleeve rod, one end of the sleeve rod is slidably connected to the inside of the sleeve, and a return spring is fixedly connected between the end of the sleeve rod extending into the sleeve and the inner wall of the sleeve. The other end of the sleeve is fixedly connected to the fixing plate 22, and the other end of the sleeve rod is fixedly connected to the connecting rod 13.

[0047] A first transmission assembly and a second transmission assembly are provided on the top of the tank air filter body 1. When the fixed shaft 10 moves, the first transmission assembly drives the fixed shaft 10 to rotate. When the fixed shaft 10 moves, the second transmission assembly drives the connecting rod 13 to move up and down.

[0048] The first transmission assembly includes a gear 7, which is fixedly sleeved on the second threaded rod 6. The upper surface of the tank air filter body 1 is fixedly connected with a first rack 8 and a second rack 9. The gear 7 is meshed with the first rack 8 and the second rack 9.

[0049] The first rack 8 and the second rack 9 are arranged along the sliding direction of the moving block 5. The first rack 8 is located at one end of the filter plate 21 close to the fixed block 2, and the second rack 9 is located at the other end of the filter plate 21. There is a distance between the central axes of the first rack 8 and the second rack 9.

[0050] There are two second transmission assemblies, which are symmetrically arranged on the top of the tank air filter body 1, and the filter plate 21 is located between the two second transmission assemblies.

[0051] The second transmission assembly includes a tooth plate 15, which is fixedly connected to the upper surface of the tank air filter body 1. The tooth plate 15 is composed of a bottom plate and a plurality of protrusions, the bottom plate is fixedly connected to the top of the tank air filter body 1, and a plurality of protrusions are fixedly connected to the upper surface of the bottom plate at intervals, and the upper surface of the protrusion is inclined. The shapes of the two ends of the protrusion are right triangles, and one of the right angles of the right triangle is fixed to the bottom plate.

[0052] The bottoms of both ends of the connecting rod 13 are fixedly connected with the moving rod 12 . The end of the moving rod 12 away from the connecting rod 13 is hemispherical in shape, and the hemispherical end of the moving rod 12 is movably arranged on the protrusion.

[0053] Working principle:

[0054] When installing the guide frame 16 , the guide frame 16 is pushed toward the inside of the tank air filter body 1 , and the guide block 19 also slides on the guide shaft 20 .

[0055] As the guide frame 16 slides, the side surface of the guide frame 16 at the slot will squeeze the hemispherical protrusion of the slide bar 17 , causing the slide bar 17 to slide toward the inside of the receiving slot and compress the spring 18 .

[0056] When the guide frame 16 is completely located inside the tank air filter body 1, the slot is connected to the receiving slot. At this time, under the effect of the elastic force of the spring 18, the slide bar 17 is pushed, so that the hemispherical protrusion of the slide bar 17 slides inside the slot, and then the guide frame 16 is positioned.

[0057] The filter plate 21 is located at the top of the tank air filter body 1 to facilitate dust filtering.

[0058] When the filter plate 21 needs to be cleaned, the motor 3 is started, and the output shaft of the motor 3 rotates forward, driving the first threaded rod 4 to rotate, so that the moving block 5 slides on the top surface of the liquid tank air filter body 1 toward the side away from the motor 3. The moving block 5 also drives the second threaded rod 6 and the fixed shaft 10 to move above the filter plate 21.

[0059] The connecting rod 13 will also be driven to move on the top of the filter plate 21, and the moving rod 12 will move on the top of the tooth plate 15. During the movement of the moving rod 12, the bottom end of the moving rod 12 slides on the protrusion of the tooth plate 15. The protrusion will gradually push the moving rod 12 upward, so that the connecting rod 13 moves upward, the telescopic rod 14 is shortened, and the return spring in the telescopic rod 14 is compressed.

[0060] After the moving rod 12 leaves the inclined surface of the protrusion, since the shapes of the two ends of the protrusion are right-angled triangles, one of the right-angled sides of the right-angled triangle is fixed on the bottom plate. Therefore, under the action of the return spring, the telescopic rod 14 will push the moving rod 12 and the connecting rod 13 to move downward, so that the knocking block at the bottom of the connecting rod 13 pushes the filter plate 21 downward, thereby knocking the filter plate 21, causing the filter plate 21 to vibrate, and the dust in the filter plate 21 can be shaken off.

[0061] Then the moving rod 12 moves to the next protrusion, so that during the movement of the fixed shaft 10, the knocking block will knock the filter plate 21 for many times.

[0062] As the fixed shaft 10 moves, the second threaded rod 6 moves together with the moving block 5, and the gear 7 gradually contacts the second rack 9, so that during the movement of the gear 7, the second rack 9 drives the gear 7 to rotate.

[0063] The gear 7 drives the second threaded rod 6, the fixed shaft 10, the cleaning brush 11, and the connecting rod 13 to rotate. When the second threaded rod 6 rotates inside the moving block 5, the second threaded rod 6 moves inside the moving block 5, driving the gear 7 to move on the top of the second rack 9.

[0064] When the fixed shaft 10 rotates 180 degrees, the gear 7 just leaves the second rack 9. At this moment, the fixed shaft 10 continues to move, and the gear 7 does not rotate. Therefore, the cleaning brush 11 is rotated to the top of the filter plate 21.

[0065] The motor 3 is started, and the output shaft of the motor 3 is reversed. The first threaded rod 4 rotates, and the moving block 5 slides toward the side close to the motor 3, driving the cleaning brush 11 to move on the top of the filter plate 21, so that the cleaning brush 11 cleans the top of the filter plate 21.

[0066] As the fixed shaft 10 moves, the second threaded rod 6 moves with the moving block 5, and the gear 7 gradually contacts the first rack 8. In this way, the first rack 8 drives the gear 7 to rotate during the movement of the gear 7.

[0067] When the second threaded rod 6 is rotated inside the moving block 5 , the second threaded rod 6 will move inside the moving block 5 , driving the gear 7 to move on the top of the first rack 8 .

[0068] When the fixed shaft 10 rotates 180 degrees, the gear 7 just leaves the first rack 8. Then the connecting rod 13 can be rotated to the top of the filter plate 21 again, so that the knocking block continues to knock the filter plate 21.

[0069] When the filter plate 21 needs to be removed after long-term use, the guide frame 16 is pulled toward the outside of the tank air filter body 1, and the side of the guide frame 16 will press the hemispherical protrusion of the slide bar 17, so that the slide bar 17 slides toward the inside of the receiving groove, and the hemispherical protrusion of the slide bar 17 leaves the slot and compresses the spring 18. The filter plate 21 can be slid to the outside of the tank air filter body 1, so as to be removed and replaced.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
