Specifically, as shown in fig. 34, a limit projection 221 may be provided on a side of the edge bar 22 facing the outside of the case 1, and be projected toward the outside of the case 1, thereby facilitating processing and installation. Of course, the present invention is not limited thereto, and the limiting protrusion 221 may be disposed on a side of the edge strip 22 facing the inside of the housing 1 and protruded toward the inside of the housing 1. The cross-section of the stopper protrusion 221 may be octagonal. Of course, the shape of the cross section of the limit projection 221 is not limited to the octagon, and for example, the shape of the cross section of the limit projection 221 may also be a circle, a quadrangle, or the like.

Alternatively, the edge bar 22 may be provided with a bar-shaped protrusion extending in the moving direction of the filter net 2, and the bar-shaped protrusion may be provided on a side of the edge bar 22 facing the outside of the housing 1 and protruding in the direction facing the outside of the housing 1 (this example is not shown). From this, the bar-shaped protrusion can avoid filter screen 2 to move back and forth in the left-right direction, prevent filter screen 2 from causing filter screen 2 to move into in casing 1 and move out unsmoothly in the in-process of removal because of the removal of left-right direction, guarantee the reliability that filter screen 2 moved in casing 1, guarantee that filter screen 2 can be smooth move out in casing 1 or move into in casing 1.

In some embodiments of the present invention, the upper end of the edge strip 22 is provided with a limit structure 382, and when the upper end of the edge strip 22 is close to the driving gear 36, the limit structure 382 stops the driving gear 36 from moving (this example is not shown). Therefore, the filter screen 2 can be prevented from being separated from the driving gear 36 in the downward movement process to cause the filter screen 2 to fall off, and the downward movement reliability of the filter screen 2 is ensured. Alternatively, the limit feature 382 may be configured by a limit switch, a light sensitive switch, or by deformed gear teeth on the upper end of the edge 22. Therefore, the diversity of the limiting structure can be increased.

Further, as shown in fig. 29-32, the driving device further comprises a coaxial gear 37 and a rack 38, the coaxial gear 37 and the driving gear 36 rotate coaxially, the rack 38 and the filter screen 2 move in the same direction, and the rack 38 is suitable for being clamped with the filter screen 2, wherein the driving device has a first meshing state, a second meshing state and a third meshing state.
