preferably, lower spray pipe 821 can produce atomization effect under the effect of high-pressure water flow, in dry and haze weather, can the humidification or fall the haze, should set up and can expose spray pipe 82 corresponding part when needs spray irrigation or atomizing, resets spray pipe 82 when need not the operation to guarantee that shower nozzle device 8 can not blockked up by impurity etc. guarantees its life, and two upper and lower shower nozzles can increase the spray range or realize the different effect of spraying.

The system for recycling the rainwater in the sponge city can utilize the solar panel 11 to absorb sunlight to convert the light energy into electric energy for storage, when the rain falls, the water flow of the drain pipe 1 flows to the first filter 2, the controller 12 controls the motor 13, the purifier 4 and the first water pump 7 to be started, the impeller 24 and the filter barrel 23 of the first filter 2 are driven by the motor 13 to rotate, collect the rainwater and preliminarily filter the rainwater, the filtered rainwater enters the second filter 3 to be further filtered, the purified rainwater enters the purifier 4 to be purified, the purified rainwater is pumped into the water storage tank 5 by the first water pump 7 to be stored, when the green plants lack water, the controller 12 starts the second water pump 6, one of the cavities of the second water pump 6 works, the controller 12 controls the first control valve 9 or the second control valve 10 to be started, so that the water flow enters the spray head device 8, and the corresponding upper spray pipe 824 or lower spray pipe 821 is exposed, spray work, it is preferred, when needing to air humidification or falling the haze, lower spray pipe 821 stretches out and carries out the atomization.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
