CN-224206316-U - Fan structure of Roman umbrella

Abstract

The utility model provides a fan structure of a Roman umbrella, and belongs to the technical field of Roman umbrellas. It has solved the problem that current fan structure can influence the umbrella stand and accomodate. The fan structure of the Roman umbrella comprises an umbrella frame, wherein the umbrella frame comprises a lower umbrella disc and lower umbrella ribs which are evenly hinged with the lower umbrella disc in the circumferential direction, an electric fan driving piece is connected to the lower umbrella disc, a rotor is fixedly connected to a driving shaft of the electric fan driving piece, an end portion of one end of the driving shaft is connected with an illumination lamp holder, a rotating shell is rotationally connected to the driving shaft through a bearing, a stator matched with the rotor is fixedly arranged in the rotating shell, the rotating shell is located between the illumination lamp holder and the lower umbrella disc, a plurality of fan blades are hinged to the outer edge of the rotating shell in the circumferential direction, and the outer edge of each fan blade is located in the outer edge of the illumination lamp holder in the radial direction when the fan blades are folded between the lower umbrella disc and the illumination lamp holder. When the fan structure of the Roman umbrella is stored, the fan blades are hidden, so that the umbrella folding of the umbrella stand is not influenced, and the normal storage of the umbrella stand can be ensured while the fan blows.

Description

Fan structure of Roman umbrella Technical Field The utility model belongs to the technical field of Roman umbrellas, and relates to a fan structure of a Roman umbrella. Background The traditional roman umbrella only has the functions of sunshade and illumination, when the umbrella is used in hot weather, the existing roman umbrella is generally provided with a handheld fan and the like, and for the convenience of use, a fan is connected to an umbrella frame of a part of roman umbrella, and the rotation of the fan can be realized through switch control after the roman umbrella is unfolded. As disclosed in chinese patent application CN101077243B, a multifunctional umbrella for electrical devices is disclosed, comprising a pole and an electric function control panel supported on the pole and located at a position accessible to a user, comprising a control circuit having an input port for electrically connecting a power source and a plurality of control ports selectively connected to the electrical devices, a control device electrically connected to the control circuit, each electrical device being selectively controlled in a switching mode, a canopy frame comprising an umbrella hub suspended and supported on the pole for supporting the electrical device, a plurality of long ribs extending from the umbrella hub to the outside circumference, the multifunctional umbrella further comprising a fan system comprising a ventilation power source unit supported on the umbrella hub, a fan motor rotor rotatably coaxially fixed on the outer wall of the umbrella hub, and an electrically coupled ventilation power source unit, a plurality of fan blades spaced fixed on the fan motor rotor, the fan blades rotating when the fan motor rotor is actuated to rotate, producing an air flow, the fan motor rotor further comprising a plurality of angle blade hinges She Jiaolian to attach to the inside of the preset angle. Above-mentioned structure is through being fixed with motor fan rotor on umbrella pivot, a plurality of flabellum intervals are fixed on fan motor rotor to realize the installation to the flabellum through angle leaf hinge, when the flabellum does not use, the perpendicular put in the outside of umbrella pivot, when accomodating the umbrella stand, the rib of connecting on the umbrella pivot also can swing to draw in, consequently the flabellum in the umbrella pivot outside receives the damage when the umbrella stand draws in easily, in the in-service use, need avoid the flabellum when the umbrella stand is accomodate, has led to the drawing in of umbrella stand to receive the influence.
