Description

Umbrella with fan

Technical field

The present invention relates to an umbrella, and more particularly to an umbrella with an electric fan.

Background technique

At present, the umbrellas used by people, in the hot weather in midsummer, can block the strong sunlight and avoid the ultraviolet rays of the sun directly illuminating people's bodies, but the umbrellas can't stop the hot and hot weather, people work under the umbrella and leisure time. If you grow a little longer, you will feel very stuffy, not cool, feel uncomfortable, and sometimes it will heatstroke, affecting people's work and physical and mental health.

Chinese Utility Model Patent Application Publication No. "CN 2558252" The utility model named "a solar umbrella with a fan" discloses a fan with a fan, the solar umbrella with a fan, which comprises an umbrella top protection head 2, an rib 4, a support rib 6, The umbrella surface, the return spring 7, the movable support handle 8, the umbrella rod 9, the umbrella control switch 10, and the handle 11 are characterized in that the umbrella rod 9 is provided with an electric fan, and the shaft of the DC drive motor 1 of the electric fan is the umbrella rod 9 The electric fan is located between the supporting rib 6 and the rib 4; the solar pole 3 is disposed on the yoke 9 between the umbrella top protecting head 2 and the rib 4, and the battery 12 is disposed in the handle 11, the solar panel 3 is connected to the battery 12 by a wire passing through the cavity of the umbrella rod 9; the battery 12 is connected to the DC drive motor 1 by a wire passing through the cavity of the umbrella rod 9.
