Multifunctional water circulation curtain

The invention discloses a multifunctional water circulation curtain. The curtain comprises a circulating water storage tank and a flexible 'U'-shaped circulating water band, wherein a water stop sealing strip located at one side of the upper part of a flexible hose is paved in the bottom of the circulating water storage tank; the circulating water storage tank is communicated with a water inlet pipe and a water drain pipe, wherein the water inlet pipe is provided with a water inlet valve, the water drain pipe is provided with a drain valve, and the water inlet pipe is serially connected with a water heater through a guide pipe on which a water outlet valve is arranged. The multifunctional water circulation curtain provided by the invention is simple in structure, and convenient to dismount and operate. In summer, water can enter the circulating water storage tank through the water inlet pipe and then flows in the flexible 'U'-shaped circulating water band to circularly flow through a flexible guide pipe if the water inlet valve is opened and the water outlet valve is closed, so as to cool and prevent sunstroke indoors; in winter, the high temperature water heated by the water heater is stored in the circulating water storage tank through the guide pipe and the water inlet pipe, and then flows in the flexible 'U'-shaped circulating water band to circularly flow through a flexible guide pipe if the water inlet valve is opened and the water outlet valve is closed, so as to heat and defend against the cold, therefore the water resources and energy can be used sufficiently, energy saving and environmental protection can be realized, and cleanliness can be realized without pollution.
