Description

Technical Field

[0001] The utility model belongs to the technical field of folding fans, and particularly relates to a magnetic fan. Background Art

[0002] A folding fan is a foldable fan made of bamboo, wood or ivory as the fan frame, and tough paper or silk as the fan cover.

[0003] Most common folding fans are in a fan shape of less than 180 degrees when unfolded. When in use, you need to hold the fan ribs on both sides with your hands. Your hands will feel sore after using for a long time. Therefore, a folding fan that can be unfolded 360 degrees has appeared on the market. When the folding fan is fully unfolded, the fan ribs on both sides will lean against each other. For example, a folding fan disclosed in Chinese utility model patent application CN201620419749.4 includes a left fan handle, a right fan handle and a folding fan surface located between the left fan handle and the right fan handle, and the left fan handle and the right fan handle are both metal fan handles; an axis is welded to the front end of the left fan handle, a first fixing hole is opened at the end, and a connecting groove is opened in the middle; a miniature placement box with a fragrance hole is connected to the middle of the right fan handle, and a second fixing hole is opened at the end and is connected to a fixing belt; first buckles that can be buckled on the first fixing hole are installed on both sides of the fixing belt; an arc-shaped telescopic rod is connected between the first fixing hole and the second fixing hole.

[0004] The above structure can fix the angle between the left fan handle and the right fan handle through the arc-shaped telescopic rod, so as to control the size of the folding fan surface according to the user's needs. However, the folding fan surface is exposed during the folding process and is prone to accidental damage, thus affecting the service life of the folding fan. In addition, in this structure, the left fan handle and the right fan handle are directly hinged. During the folding process, the position of the folding fan surface close to the axis is subjected to greater force, which affects the folding of the folding fan and is easily damaged after long-term use.
