During normal spraying, the paint passes through the two filters for filtering, the movable ring 29 and the second filter 30 are pressed to the lowest point by the paint, the connecting membrane 13 receives the pressure of the paint, the top block 15 is pressed into the shell 14, the first spring 16 is compressed, the air in the shell 14 enters the second L-shaped shell 32, the second movable plate 33 moves upward, and the third spring 34 is compressed. During the replacement of the circuit board, the paint no longer exerts pressure on the connecting membrane 13. Under the action of the first spring 16, the top block 15 moves upward, and under the action of the third spring 34, the second movable plate 33 moves downward. The second movable plate 33 pulls the movable block 36 downward through the third connecting rope 35, and the movable block 36 drives the first rack 37 to move downward. The first rack 37 drives the second rack 40 and the L-shaped plate 39 to move upward through the first gear 38. The L-shaped plate 39 drives the vertical plate 43 to move upward. The vertical plate 43 drives the movable ring 29 and the second filter 30 to move upward through the blocking plate 42, so that the second filter 30 is away from the first filter 28. When the first gear 38 is pulled upward, the second gear 38 is pulled upward, and the L-shaped plate 39 drives the vertical plate 43 to move upward. The vertical plate 43 drives the movable ring 29 and the second filter 30 to move upward through the blocking plate 42, so that the second filter 30 is away from the first filter 28. After the second filter screen 30 rises to a certain height, the second gear 45 meshes with the tooth block 49. Under the action of the baffle 50, the tooth block 49 cannot rotate upward, so the second gear 45 continues to move upward to the highest position, and the tooth block 49 can drive the second gear 45 to rotate. The second gear 45 drives the second filter screen 30 to rotate through the flexible rotating rod 44, so that the second filter screen 30 rotates exactly 180 degrees. When the paint is sprayed again, the paint can impact the second filter screen 30 located at the highest point downward to the lowest point. The second gear 45 can drive the tooth block 49 to rotate downward through the tooth block 49, and the connecting line 51 is stretched. When the second gear 45 leaves the tooth block 49, under the action of the connecting line 51, the tooth block 49 is reset to prevent the tooth block 49 from driving the second filter screen 30 to rotate during the descent of the second filter screen 30. After the second filter screen 30 is impacted to the lowest point, the impurities stuck in the holes of the second filter screen 30 will be impacted into the gap 31 by the paint, and the impurities are collected into the opening 41 along the first filter screen 28, so as to achieve the effect of dredging the second filter screen 30. When the second filter screen 30 is impacted downward by the paint, the second gear 45 drives the tooth block 49 to rotate. To prevent the second gear 45 from rotating, the first annular rubber block 52 and the second annular rubber block 53 abut against each other to generate friction, thereby preventing the second gear 45 from rotating at will. A small amount of bubbles will be generated when the paint passes through the two filter screens. The first conical plate 54 can be provided to guide the paint and reduce the bubbles generated after the paint passes through the filter screen. Bubbles will be generated when the paint impacts the bending part of the L-shaped tube 4. The second conical plate 55 can also reduce the bubbles in the paint and play a guiding role.
