Abstract

This utility model provides a spray cooling structure for a double-headed umbrella, belonging to the technical field of double-headed umbrellas. It solves the problems of high processing costs and difficult installation of existing umbrella spray cooling structures. The double-headed umbrella spray cooling structure includes a hollow upright pole, with an umbrella frame slidably connected to the upright pole vertically. An umbrella fabric is placed on the umbrella frame. The top of the hollow upright pole has a main upper umbrella plate located in the middle of the umbrella fabric. Two auxiliary upper umbrella plates extend outwards from the left and right sides of the umbrella frame. The spray cooling structure includes a connecting hose. The middle or lower end of the hollow upright pole has a clearance inlet for the connecting hose to enter the hollow upright pole's inner cavity, and the upper end has a clearance outlet for the connecting hose to exit the hollow upright pole's inner cavity. This double-headed umbrella spray cooling structure has minor improvements, reducing processing costs. Furthermore, during installation, the connecting hose is directly threaded onto the upright pole, and then the water pump and water pump nozzle are installed, making installation convenient.
