Description

Technical Field

[0001] The invention relates to the technical field of rain gear, and in particular to an umbrella holder with a fan and an umbrella. Background Art

[0002] An umbrella generally includes an umbrella pole, an umbrella handle, an umbrella cap, umbrella ribs, an umbrella holder and an umbrella cloth. An umbrella nest is set on one end of the umbrella pole, and the umbrella holder passes through the umbrella cloth and combines with the umbrella cap to achieve closure. The other end is connected to the umbrella handle in a retractable or non-retractable form and then closed. The umbrella holder is equipped with umbrella ribs (long lines / main umbrella ribs) that support the umbrella surface. The umbrella ribs (long lines) are connected to the umbrella ribs (short lines / secondary umbrella ribs) installed on the umbrella nest to form an umbrella frame, which cooperates with the umbrella nest or the umbrella nest and the handle to achieve the functions of shrinking and folding the umbrella frame. When the umbrella frame is opened, the umbrella usually has the functions of sunshade and rainproof. However, for users who are outside in hot weather, traditional umbrellas only have the function of sunshade. Users under the umbrella still feel very hot, resulting in a poor user experience.

[0003] The existing umbrellas with fans usually simply put the fan blades on the top of the umbrella pole, or embed them into the housing of the handheld end of the umbrella handle. The above solutions have the following disadvantages:

[0004] The fan and the umbrella are two different products, with poor integration and unsightly appearance. The fan is mounted on the top of the umbrella pole, and the umbrella cloth cannot be folded and retracted when not in use. When in use, the fan blades on the umbrella pole are exposed, which is easily disturbed by the wind from the outside. The wind is unstable and can easily get caught in the user's hair, posing a safety hazard. Although the handle of an umbrella with a fan embedded in the handle solves the above problems through the embedded fan design, the handle of this type of umbrella is usually large and inconvenient to hold. When the umbrella is held in hand, the wind outlet is concentrated (usually on the chest), the heat dissipation effect above the human body is poor, and the overall user experience is poor.
