The water spray pipe 301 is rotatably arranged in the pretreatment chamber and one end thereof passes through the pretreatment chamber. The gear 4 is arranged on the outside of one end of the water spray pipe 301 passing through the pretreatment chamber. The plurality of nozzles 302 are distributed on the outside of the water spray pipe 301 in a linear array. The water pump 303 is arranged on the rear side of the housing 1 for supplying water to the water spray pipe 301. The water suction pipe 304 and the water outlet pipe 305 are respectively arranged at the water inlet end and the water outlet end of the water pump 303. The bottom end of the water suction pipe 304 passes through the pretreatment chamber. The top end of the water outlet pipe 305 is connected with the water spray pipe 301 and the water outlet pipe 305 is a hose.

[0035] By adopting the above technical solution, when the filter screen 2 needs to be cleaned, the water pump 303 can extract the filtered water in the pretreatment chamber through the suction pipe 304, and then the water flows through the suction pipe 304, the outlet pipe 305 and the spray pipe 301 in turn, and finally sprayed out through the nozzle 302 to clean the filter screen 2.

[0036] Reference Figure 2 The rotating mechanism 5 includes a mounting plate 501, an electric push rod 502 and a tooth plate 503. The mounting plate 501 is arranged on the rear side of the box body 1, the electric push rod 502 is arranged on one side of the mounting plate 501, and the tooth plate 503 is arranged on one side of the electric push rod 502. The tooth plate 503 is meshed with the gear 4 to drive the gear 4 to rotate reciprocatingly.

[0037] By adopting the above technical solution, the electric push rod 502 drives the tooth plate 503 to move back and forth, and the reciprocating movement of the tooth plate 503 can drive the gear 4 to rotate back and forth, so that the nozzle 302 on the water spray pipe 301 can rotate back and forth, thereby ensuring the cleaning effect of the filter screen 2.

[0038] Reference Figure 3 A discharge port 6 is provided on one side of the interior of the pretreatment chamber, a collecting cover 7 is provided on the left side of the box body 1 at the discharge port 6, and a discharge pipe 8 is provided at the bottom end of the collecting cover 7.

[0044] Working principle: When the utility model is in use, the electrical components appearing in the present application are all externally connected to a power source and a control switch. When it is necessary to clean the filter screen 2 in the pretreatment chamber, the water pump 303 works to extract the filtered water in the pretreatment chamber through the suction pipe 304, and then the water flows through the suction pipe 304, the outlet pipe 305 and the spray pipe 301 in turn, and finally is sprayed out through the nozzle 302 to clean the filter screen 2. At the same time, the electric push rod 502 works to push the tooth plate 503 to move back and forth, and the reciprocating movement of the tooth plate 503 can drive the gear 4 to rotate back and forth, so that the nozzle 302 on the spray pipe 301 can rotate back and forth, thereby ensuring the cleaning effect of the filter screen 2, and then the impurities cleaned out of the filter screen 2 can enter the collection cover 7 through the discharge port 6, and finally the discharge pipe 8 can be opened to process the impurities, so that the filter screen 2 does not need to be disassembled when it is cleaned, and thus will not affect the preparation efficiency of pure water.
