[0028] The specific flushing mechanism 3 also includes an inlet valve 306 fixedly connected to the outer surface of the water inlet pipe 1, and the outer surface of the water inlet pipe 1 is fixedly connected to a drain pipe 304, and the outer surface of the drain pipe 304 is fixedly connected to a drain valve 305, wherein the outer surface of the water tank 308 is fixedly connected to a sampling valve 301, and the end of the water tank 308 away from the connecting pipe 309 is fixedly connected to the water outlet pipe 101.

[0029] The water inlet valve 306 and the water outlet valve 307 are further rotated to stop filtering the water, and then the water pump 303 is started. The water pump 303 pumps the water source in the water tank 308 into the connecting pipe 309, so that the water in the water tank 308 reversely flushes the outer surfaces of the third filter plate 208, the second filter plate 207 and the first filter plate 206, thereby facilitating the flushing of impurities adsorbed on their surfaces. Then, the drain valve 305 is rotated so that the impurities in the flushing pipe 302 can be discharged from the drain pipe 304, thereby facilitating the cleaning of the impurities in the filter frame 203. Example

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The inner wall of the filter frame 203 is slidably connected to a sealing shell 204, the lower surface of the sealing shell 204 is fixedly connected to a lower sealing gasket 209, and the side surface of the sealing shell 204 is fixedly connected to a side sealing gasket 210.

[0031] Specifically, the inner wall of the filter frame 203 is fixedly connected with multiple groups of mounting rings 205 at intervals, and the outer surface of the mounting ring 205 is slidably connected with the first filter plate 206, the second filter plate 207 and the third filter plate 208, wherein the first filter plate 206, the second filter plate 207 and the third filter plate 208 are sequentially arranged on the inner wall of the filter frame 203, and the calibers are reduced successively, so as to facilitate multiple filtration of the water source, wherein the outer surfaces of the lower sealing gasket 209 and the side sealing gasket 210 are both fitted with the inner wall of the filter frame 203, and the upper surface of the sealing shell 204 is fitted with the mounting plate 201, and the outer surface of the mounting plate 201 is threadedly connected with multiple groups of bolts 202, and the other end of the bolt 202 is threadedly connected to the upper surface of the filter frame 203, and the inner wall of the filter frame 203 is provided with a groove used in conjunction with the lower sealing gasket 209 and the side sealing gasket 210, thereby increasing the sealing degree between the filter frame 203 and the sealing shell 204.

[0032] The bolt 202 is further turned to separate the mounting plate 201 and the filter frame 203, and then the outer surface of the sealing shell 204 is grasped to make the sealing shell 204 slide out from the inner wall of the filter frame 203, thereby facilitating the removal of the first filter plate 206, the second filter plate 207 and the lower sealing gasket 209 from the filter frame 203, thereby facilitating their replacement.

[0033] Working principle: When in use, turn the water inlet valve 306 and the water outlet valve 307, so that water can flow from the filter frame 203 to the water tank 308, and pass through the first filter plate 206, the second filter plate 207 and the third filter plate 208 to facilitate multiple filtration of the water source, so that impurities are adsorbed on the outer surfaces of the first filter plate 206, the second filter plate 207 and the third filter plate 208, so that the filtered water source can be accumulated in the water tank 308, and the excess water is discharged from the water outlet pipe 101, and then by turning the sampling valve 301, it is convenient to sample and test the filtered water source in the water tank 308. When the water flow speed in the water outlet pipe 101 decreases, turn the water inlet valve 306 and the water outlet valve 307 to stop filtering the water, and then start the water pump 303. The water pump 303 pumps the water source in the water tank 308 into the connecting pipe 309, so that the water in the water tank 308 flows back to the first filter plate 206, the second filter plate 207 and the third filter plate 208. The outer surfaces of the third filter plate 208, the second filter plate 207 and the first filter plate 206 are flushed, so as to facilitate the washing off of impurities adsorbed on their surfaces, and then the drain valve 305 is rotated so that the impurities in the filter frame 203 can be discharged from the drain pipe 304, so as to facilitate the cleaning of the impurities in the filter frame 203, thereby extending the service life of the first filter plate 206, the second filter plate 207 and the third filter plate 208. When the first filter plate 206, the second filter plate 207 and the third filter plate 208 need to be replaced, the bolt 202 is rotated to separate the mounting plate 201 and the filter frame 203, and then the outer surface of the sealing shell 204 is grasped so that the sealing shell 204 slides out from the inner wall of the filter frame 203, so as to facilitate the removal of the first filter plate 206, the second filter plate 207 and the lower sealing gasket 209 from the filter frame 203, so as to facilitate their replacement.
