Abstract

The invention relates to a take-up device. The take-up device comprises a retarding gear box, a winding reel and a limiting cover which are sequentially arranged in the axial direction, a center shaft is arranged on the retarding gear box in the axial direction, the center shaft axially penetrates through the winding reel and is fixedly connected with the limiting cover, and a containing cavity is formed in the side, facing the limiting cover, of the winding reel. A coil spring is arranged in the containing cavity, one end of the coil spring is fixedly connected with the center shaft, the other end of the coil spring is fixedly connected with the winding reel, and a speed reducing mechanism in linkage with the winding reel is arranged in the retarding gear box. The speed reducing mechanism is composed of a transmission gear set and a speed reducing gear set, the transmission gear set is in linkage with the winding reel, the speed reducing gear set is composed of at least one speed reducing gear piece, and each speed reducing gear piece comprises a speed reducing gear in linkage with the transmission gear set and a rotating shaft which is coaxially arranged and used for supporting the speed reducing gear in a rotating mode. The two ends of each rotating shaft are installed in the retarding gear box. The effect that a power line can be wound at a constant speed is achieved.

Description

technical field [0001] The present application relates to the field of household appliances, in particular to a wire take-up device and a hair dryer thereof. Background technique [0002] The hair dryer is a combination of a set of heating wires and a high-speed small fan. When energized, the heating wire will generate heat, and the wind blown by the fan will become hot air after passing through the heating wire. The hair dryer is mainly used for drying and shaping of hair, but it can also be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, and art. [0003] Today's hair dryers usually use an external power cord to supply power to the fan and the heating wire, but this kind of hair dryer with an external power cord needs to wind the power cord on the handle or on the handle when storing the wires. On the housing of the hair dryer for storage. Another commonly used way to rewind the power cord is to build a ro...
