Since a large amount of impurities fall into the bottom of the housing 1 when the cleaning member 22 cleans the filter screen 3, the impurities are discharged, when the impurities are discharged, both ends of the housing 1 are required to be sealed, then the air pump 275 pumps out the air in the storage tank 272, so that the storage tank 272 is in a negative pressure state, then the third switch valve 271 and the fourth switch valve 273 are opened, water and impurities in the housing 1 can be rapidly pumped into the storage tank 272, then the third switch valve 271 and the fourth switch valve 273 are closed, and the fifth switch valve 274 is opened, so that the impurities in the storage tank 272 are discharged.
Referring to fig. 4 and 10: the cleaning device 2 further comprises a diverter 28; the splitter 28 is arranged on the side of the support device 23 near the water inlet of the housing 1.
By providing a diverter 28 to divert the incoming water flow, the water flow is prevented from directly impacting cleaning element 22, thereby causing damage to cleaning element 22.
Referring to fig. 5: the filter device further comprises a guide rail 31; the guide rail 31 is of an annular structure, the guide rail 31 is fixedly arranged on the inner wall of the shell 1 along the axis of the shell 1, and the filter screen 3 is in running fit with the guide rail 31.
Through set up guide rail 31 on the inner wall of shell 1 to set up filter screen 3 in guide rail 31, guaranteed that filter screen 3 keep away from the week side of running through pipe 21 when filtering and be difficult for taking place deformation, guaranteed the normal filtration function of filter screen 3.
Referring to fig. 9: the length of the slider 211 is longer than the length of the through slot.
So when slider 211 is pushed, slider 211 can be with leading to the groove shutoff all the time, avoided the water in the shell 1 to enter into the spout through leading to the groove, if the length of leading to the groove is longer than the length of slider 211, slider 211 can lead to in the rivers spout in the shell 1 when sliding, and the water in shell 1 has the impurity when filtering, the impurity is surging into in the spout along with rivers, when slider 211 resets, rivers can be extruded nevertheless, and impurity can't guarantee to extrude completely, after long-time operation, pile up too much impurity in the spout, can make slider 211 can't drive clearance piece 22 completely and slide to the one end of leading to the groove, lead to clearance piece 22 can't contact with filter screen 3.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
