Atomization spraying cooling umbrella

The utility model relates to the technical field of cooling umbrellas, and provides an atomizing and spraying cooling umbrella which comprises an umbrella body and an atomizing and spraying device. A sky radiation refrigeration material layer and a hydrogel material layer are arranged on the surface of the umbrella body, the sky radiation refrigeration material layer is used for reducing the surface temperature of the umbrella body and condensing water vapor in the air under the condition of certain humidity, and the hydrogel material layer adsorbs the water vapor in the atmosphere at night. In the daytime, water vapor is desorbed by sunlight irradiation and liquid water is formed; a water storage tank is arranged on the umbrella body and used for containing condensate water on the surface of the umbrella body and liquid water desorbed from the hydrogel material layer. The atomization spraying device is communicated with the water storage tank; water is taken from the air through the sky radiation refrigerati
