Description

Portable whirlwind parasols

Affiliated technical field

The solar protection devices that the utility model relates to a kind of summer goes out, especially when keeping the sun off, not electricity consumption can produce the portable sunshade umbrella that air flows by manpower.

Background technology

Known portable band wind parasols is that micromachine is installed on umbrella at present, rotates the generation air with battery-operated fan blade and flows.Because of motor is too little, wind-force is not enough, and motor is too big, increases the weight and volume of umbrella again, is not easy to carry, and produced simultaneously useless day battery also can influence environmental protection.If a hand-held umbrella, a Hand swing fan also makes troubles for answering cell phone or portable article.

Summary of the invention

In order to overcome the deficiency of existing portable sunshade umbrella, the utility model provides a kind of portable whirlwind parasols.This portable whirlwind parasols can not only keep the sun off to the direct projection of human body.Simultaneously can one-handed performance, make that air flows in the umbrella, quicken to distribute the heat that human body produces, make the people feel comfortable convenience, do not influence answering cell phone or portable article.

The technical scheme that its technical problem that solves the utility model adopts is:

Umbrella bar with portable sunshade umbrella is an axle, is inserted in the sail ring from lower to upper successively, locating ring, and rotating ring, behind rotating cylinder and the driven wheel of differential, umbrella bar lower end is fixed on and drives umbrella handle place, box body lower end.By the triangle canvas, boom connects sail ring and rotating ring, the sail that arcs such as formation distribute.Constitute the driving box by rocking handle, capstan, drive bevel gear, driven wheel of differential, bearing and rotating cylinder, to drive box upper end rotating cylinder and be inserted in screens with rotating ring and is connected,, can drive the sail fast rotational with the rotation of thumb drive rocking handle, form moving air, and umbrella self does not rotate.

The beneficial effects of the utility model are that summer is when going out, when the direct projection of blocking sunray, can produce the heat that wind distributes human body, avoid heatstroke, left and right one-handed performance is convenient, can stretch and to receive, volume is little, and is in light weight, without battery, do not influence environmental protection, folded umbrella and straight-bar umbrella all can be provided with, and in use increase aesthetic feeling simultaneously, and wind-force is equivalent to general paper folding fan.
