A second solenoid valve 71 is installed on the surface of the water pumping pipe 7, and the water flow can be closed by cooperating with the water pumping pipe 7 through the second solenoid valve 71. The bottom of the water pumping pipe 7 is connected with a connecting pipe 72, and the bottom of the connecting pipe 72 passes through the interior of the water storage tank 1. The connecting pipe 72 facilitates the cooperation of the water pumping pipe 7 and the water pump 6 to pump out the water inside the water storage tank 1.

[0025] A connecting groove 10 is provided on one side of the interior of the water supply tank 2, and a guide plate 11 is hinged on the top of the connecting groove 10. A cylinder 12 is installed at the bottom of the inner cavity of the water supply tank 2, and a connecting rod 13 is fixedly connected to the top of the cylinder 12. The connecting rod 13 is retracted by the cylinder 12 to expand the guide plate 11. At this time, the water flowing out of the water supply tank 2 will be discharged into the connecting groove 10 through the guide plate 11 and flow into the interior of the water storage tank 9 for collection and storage. The top of the connecting rod 13 is hinged to the guide plate 11.

[0026] The front and rear sides of the inner cavity of the water supply tank 2 are fixedly connected with a partition 14, and a filter plate 15 is provided inside the partition 14. An opening for use with the partition 14 is opened on one side of the water supply tank 2. A positioning plate 16 is fixedly connected to one side of the filter plate 15.

[0027] Working principle: Water is transported by connecting the flange pipe 4 with the pipeline. At this time, the water flows into the water supply tank 2 through the guide plate 24 inside the water inlet shell 3, and then flows into the water storage tank 1 for use after being filtered through the filter plate 15. At this time, the cylinder 12 can also drive the connecting rod 13 to retract to expand the guide plate 11. At this time, the water flowing out of the water supply tank 2 will also be discharged through the guide plate 11 to the connecting groove 10 and flow into the water storage tank 9 for collection and storage. Then turn on the water pump 6 to cooperate with the water pumping pipe 7 and the connecting pipe 72 to pump out the water inside the water storage tank 1 for use. Then, when the user needs to maintain the filter plate 15 and still needs to use the water flow normally, the second solenoid valve 71 can be opened to open the two-way pipe 8, and then cooperate with the water pump 6 and the water pumping pipe 7 to pump out the water stored in the water storage tank 9 for use. Then pull the pull block 21 to drive the pull rod 20 to make the positioning ring 19 squeeze the spring 18. At this time, the pull rod 20 is separated from the inside of the positioning plate 16, and the filter plate 15 can be taken out for cleaning.
