[0033] Referring to Figure 2 The frame 2 is provided with a movable channel 21 extending along the arrangement direction of the plurality of filter sub-pieces 10 and an opening 210 communicating with the movable channel 21, and at least part of the filter sub-pieces 10 are slid into the movable channel 21 from the opening 210, and the filter sub-pieces 10 slide in the movable channel 21.

[0034] In this embodiment, all the filter sub-pieces 10 are slidably connected to the movable channel 21 along the central axis of the frame 2, and the filter sub-pieces 10 can rotate in the movable channel 21 around the central axis of the frame 2. The opening 210 of the movable channel 21 is arranged at the top of the frame 2, and the movable channel 21 has an inner side wall and an outer side wall for limiting the radial movement of the filter sub-pieces 10 along the frame 2, the outer diameter of the filter sub-pieces 10 is slightly smaller than the inner diameter of the outer side wall, and the inner diameter of the filter sub-pieces 10 is slightly larger than the outer diameter of the inner side wall. When the plurality of filter sub-pieces 10 are freely movable, under the impact of water circulation, the filter sub-pieces 10 can move up and down along the central axis of the movable channel 21 along the central axis of the frame 2 and rotate circumferentially around the central axis of the frame 2, so as to wash the residues remaining in the filter channels 101.

[0035] The height of the movable channel 21 along the central axis of the frame 2 is greater than the thickness of all the filter sub-pieces 10 after being stacked.

[0036] In order to limit the filter sub-pieces 10, the frame 2 is provided with a sealing member 211 for sealing the opening 210 at the opening 210, and the sealing member 211 is annular.

[0037] Referring to Figure 2 and Figure 5In order to better control the change of the size of the filtering channel 101, the filtering device further comprises a control member 3, which is used to drive at least part of the filtering members 10 to move and to increase or decrease the size of the filtering channel 101 during the movement. In the embodiment, the size of the filtering channel 101 refers to the cross-sectional area of the filtering channel 101 for connecting the filtering cavity 120 and the outside and for the water flow to pass through, and the increase of the filtering channel 101 refers to the increase of the distance between the adjacent filtering members 10 and the increase of the cross-sectional area of the filtering channel 101, and the decrease of the filtering channel 101 refers to the decrease of the distance between the adjacent filtering members 10 and the decrease of the cross-sectional area of the filtering channel 101. Meanwhile, in the embodiment, the space in which the filtering members 10 can move in the activity channel 21 can be changed after the movement of the control member 3, so that the cross-sectional area of the filtering channel 101 of the adjacent filtering members 10 is a variable value under the action of the water flow circulation, and the maximum value of the cross-sectional area of the filtering channel 101 under the change state can be changed by using the control member 3.
