NOVELTY - Rural solar home water purifying device comprises a water storage tank (2), where the lower part of which is connected with a waste water inlet pipe (1). The waste water inlet pipe is provided with a valve (9). The inner wall of the water storage tank is coated with a layer of deep color solar adsorbing paint (3). The shape of the inner wall of the base is adapted to that of the outer wall of the water storage tank. The upper edges of the two sides of the water storage tank are higher than that of base. The upper edges of the two sides of the base are provided with a water collecting groove.    USE - Used as a rural solar home water purifying device.    ADVANTAGE - The device reduces usage of conventional energy, is suitable for rural families, especially in drought and water scarce areas, promotes water resources of rural families, and has high economic and social benefit.    DETAILED DESCRIPTION - Rural solar home water purifying device comprises a water storage tank (2), where the lower part of which is connected with a waste water inlet pipe (1). The waste water inlet pipe is provided with a valve (9). The inner wall of the water storage tank is coated with a layer of deep color solar adsorbing paint (3). The water storage tank is arranged in a base (4). The shape of the inner wall of the base is adapted to that of the outer wall of the water storage tank. The upper edges of the two sides of the water storage tank are higher than that of the base. The upper parts of the water storage tank and base are integrally covered by an inverse U-shaped transparent water steam condensation film. The upper edges of the two sides of the base are provided with a water collecting groove for collecting the condensate water on the inner wall of the transparent water steam condensation film. The water collecting groove is oblique from one end of the base to the other end of the base. The lowest part of the slope of the water collecting groove is provided with a drain hole and is connected to the downward of a condensation water collecting pipe. The condensation water collecting pipe is connected with a water collecting box. An INDEPENDENT CLAIM is also included for application of rural solar home water purifying device, comprising opening the valve in daytime with high solar radiation strength, transporting the domestic water, municipal water or rainwater into the water storage tank through the waste water inlet pipe, closing the valve when the water is full, illuminating the light rays to the deep color solar adsorbing paint of the inner wall of the water storage tank through the transparent water steam condensation film so that the deep color solar adsorbing paint emits heat, heating the water in the water storage tank, evaporating, condensing the water after the water steam raises to the inner wall of transparent water steam condensation film, flowing the condensed water into the water collecting groove and to the upper edges of two sides of the base along with the inverse U-shaped inner wall of transparent water steam condensation film, converging into the water collecting box by the drain hole at the lowest part of the slope of the water collecting groove through the condensation water collecting pipe for domestic use.
