When in use:

under the power supply of the battery pack at the umbrella handle 2, the semiconductor refrigerating sheet 5 and the two fans are connected through a wire inside the umbrella rod 1 (the umbrella rod is made into a hollow shape, and the top of the umbrella rod is plugged by a circular piston matched with the diameter of the umbrella rod), the lower end of the semiconductor refrigerating sheet 5 is refrigerated due to the Peltier effect, the upper end of the semiconductor refrigerating sheet heats, cold air automatically sinks, hot air automatically floats upwards, but the flow rate is slow. After the double fans are additionally arranged, the air flow rate of the cold side and the hot side is increased, so that natural convection is changed into forced convection, and the heat exchange performance is improved. In addition, the circular necking air guide cover 12 is arranged inside the umbrella side, so that the section through which the internal cold air passes is reduced, and the pressure intensity of the cold air is increased according to the knowledge of hydrodynamics, and the cold air can be blown to the body of a person more intensively.

In terms of mechanical movement, after the umbrella is folded up, the top of the umbrella is at about 90 ° to the outside of the umbrella, so that the size of the blades of the fan do not interfere with movement of the frame 4 when it is folded up.

The battery pack is designed at the umbrella handle, so that the battery pack is positioned in an air supply area, heat can be well dissipated, and the battery is prevented from working at high temperature to shorten the service life of the battery. The installation location of fan is simple relatively, has significantly reduced the human cost who consumes in the course of working. In addition, the invention uses relatively few parts, so that the whole weight is proper and the normal use of people is not influenced.
