Description

TECHNICAL FIELD

[0001] The utility model relates to a wire rotation structure field especially relates to a rotation structure and electric appliance that can freely rotate electric wire. BACKGROUND

[0002] With the progress of science and technology and the improvement of people's life quality, more and more portable appliances or household appliances enter life, such as hair dryer, straightener, dryer and curling iron. When using the hair dryer, it needs to be constantly changed in position to blow the head in different positions. In the process of changing position, the hair dryer needs to be constantly moved. However, the hair dryer must be connected to the mains power supply for normal use. During the moving process, the wire will rotate, which will cause the wire to deform or break after long-term rotation, resulting in damage to the wire and safety risks. At the same time, since one end of the wire is fixedly connected to the control panel, long-term rotation will affect the flexibility of the wire, and there is a certain inconvenience in use.

[0003] Chinese patent No. CN211431419U discloses a hair dryer with a retractable wire, which is provided with a wire retraction device. The wire retraction device includes a center shaft, a spiral spring, a rotating ring in which the spiral spring is sleeved, and a brake device for preventing the rotating ring from rotating in the wire retraction direction. The inner end of the spiral spring is fixed on the center shaft, and the outer end of the spiral spring is fixed on the inner wall of the rotating ring. The fixed position of the power cord is fixed on the surface of the rotating ring. A wire slot is provided on the rotating ring. The inner end of the power cord extends into the rotating ring from the wire slot and extends out of the inner cavity of the rotating ring to be electrically connected with the circuit control module. By manually pulling the power cord, the purpose of lengthening the power cord is achieved, which is convenient for use. By pressing the retraction button, the control of the brake device on the rotating ring is released, so that the elastic force of the spiral spring drives the rotating ring to rotate and winds the power cord on the rotating ring, realizing the function of storing the power cord. The storage of the power cord is convenient, and the power cord is stored in the hair dryer, which is not only beautiful but also protects the power cord. Although this patent realizes the storage of the power cord, it cannot avoid the friction of the power cord during rotation. Long-term friction will cause damage to the wire, which poses a safety risk. UTILITY MODEL CONTENTS
