Umbrella

Abstract

The invention relates to an umbrella, in particular to an umbrella which has the wind blowing function and comprises a stay bar; the lower end of the stay bar is provided with a handle, and the upper end thereof is provided with an umbrella enclosure. The umbrella is characterized in that the stay bar comprises a top section, a middle section and a bottom section; the upper end of the top section is provided with the umbrella enclosure; the lower end of the bottom section is provided with the handle; the middle section is detachably connected and arranged between the top section and the bottom section; and the middle section is provided with a horizontally arranged through hole which is internally provided with an axial fan. Compared with the prior art, as a high-pressure cavity and a low-pressure cavity are eliminated, the umbrella reduces air resistance and has small wind force loss. As the umbrella is used for a long time, when being destroyed, the middle section can be replaced separately, thereby achieving the goal of prolonging the service life. The invention provides a wind blowing umbrella which has small wind force loss and long service life.

Description

technical field [0001] The invention relates to an umbrella, in particular to an umbrella with a blowing function. Background technique [0002] The umbrellas sold on the market now are made up of poles, umbrella surrounds, and handles, and generally only have sunshade or rainshade functions. In summer, the weather is sultry, and the air in the umbrella cannot circulate, and the user is often sweating profusely, which is extremely painful. Chinese invention patent document CN101049195A discloses a parasol with a fan, which can solve the above problems, but its structure is complicated, and special high-pressure chambers and low-pressure chambers need to be set up, and after the wind force is buffered by the high-pressure chamber and low-pressure chamber, the wind force Lost. More importantly, since the fan is installed on the pole, the mechanical strength of the pole will inevitably be reduced, making the pole easy to break. However, when the pole of this integral structur...

Chinese invention patent document CN101049195A discloses a parasol with a fan, which can solve the above problems, but its structure is complicated, and special high-pressure chambers and low-pressure chambers need to be set up, and after the wind force is buffered by the high-pressure chamber and low-pressure chamber, the wind force loss

More importantly, since the fan is installed on the pole, the mechanical strength of the pole will inevitably be reduced, making the pole easy to break. However, when the pole of this integral structure is broken, it can only be scrapped as a whole, and its service life is short.
