One end of the spray pipe 21 is inserted on the cover plate 15, and the other end extends into the wedge-shaped wire winding filter basket 142, so that when the filter basket needs to be cleaned, liquid is sucked from the liquid outlet pipe 17 and sprayed out from the rotary spray header 23 by connecting a liquid suction pump between the liquid outlet pipe 17 and the spray pipe 21. The shower valve 22 is provided at an end of the shower pipe 21 remote from the housing 11 to control the flow of water into the shower pipe 21. The rotary spray head 23 is disposed at the end of the spray pipe 21 located in the wedge wire-wound filter basket 142, which is a fan-shaped 360-degree rotary spray head, and is known to those skilled in the art, so that the structure of the rotary spray head is not specifically described herein, accordingly, the water column sprayed by the rotary spray head 23 can impact and press the inner wall of the wedge wire-wound filter basket 142, and filter residues attached to the outer part of the filter basket are washed clean from inside to outside and drop to the bottom of the filter housing.
Compared with the prior art, the internal spraying self-cleaning filter provided by the utility model has the advantages that the spraying pipe 21 is connected with the liquid outlet pipe 17 by arranging the rotary spraying device 20, and one end of the liquid outlet pipe 17 extends to the bottom of the wedge wire winding filter basket 142, so that filtered liquid is used as liquid for cleaning filter residues, and the interior of the wedge wire winding filter basket 142 can be ensured not to be polluted by people. Meanwhile, the rotary spray head 23 positioned in the wedge-shaped wire winding filter basket 142 is simple in structure, the filter basket can be flushed by the filtering liquid per se in 360 degrees without dead angles, the structure of the filter basket per se is smooth in appearance without dead angles, and cleaning is facilitated.
