Still including pushing down device 6, pushing down device 6 is equipped with connecting rod 61 including connecting rod 61, connecting block 62, jib 63 and arc piece 64 in the middle part of depression bar 55 right side, and connecting rod 61 right-hand member is equipped with connecting block 62, and the connecting block 62 bottom is equipped with jib 63, and jib 63 bottom is equipped with arc piece 64, and arc piece 64 cooperates with connecting plate 37.

When people need to replace the filter screen 38, the handle 59 is pressed downwards, the handle 59 drives the pressure rod 55 to move downwards, so that the piston 56 moves downwards to block the lower part of the hopper 22, and simultaneously the pressure lever 55 drives the connecting rod 61, the connecting block 62, the suspension rod 63 and the arc-shaped block 64 to move downwards, when the arc-shaped block 64 contacts the connecting plate 37, the connecting plate 37 is driven to move downwards, so that the filter screen 38 is far away from the clamping ring 24, the foot pedal 42 is then stepped on, causing the new filter screen 38 to rotate directly below the snap ring 24, the foot pedal 42 and handle 59 are then released, thereby the pressure lever 55 moves upwards to reset, the pressure lever 55 drives the handle 59, the piston 56, the connecting rod 61, the connecting block 62, the suspender 63 and the arc-shaped block 64 to move upwards to reset, when the arc-shaped block 64 is separated from the connecting plate 37, the connecting plate 37 moves upward to be reset, so that the new filter screen 38 moves upward to be clamped with the clamping ring 24.

The cleaning device 7 comprises a supporting table 71, a spray head 72, a spray nozzle 73 and a water pipe 74, the supporting table 71 is arranged on the right portion of the front side of the top of the bottom plate 1, the spray head 72 is arranged on the top of the supporting table 71, the spray nozzle 73 is arranged on the rear side of the spray head 72, and the water pipe 74 is arranged on the front side of the spray head 72.

After people replace the filter screen 38, the other end of the water pipe 74 is externally connected with a water faucet, so that water is transmitted to the spray head 72 through the water pipe 74, the spray nozzle 73 sprays the water onto the replaced filter screen 38, the filter screen 38 is cleaned, and after the cleaning is finished, the water pipe 74 is separated from the water faucet.
