  • Patent number: 11588273
    Abstract: A connecting-fixing structure, used for detachably connecting a main body of an electrical appliance with a power cord, includes a connection end, a locking member, and a rotating sleeve. The locking member includes a supporting shaft and a locking portion which rotates by the supporting shaft as a fulcrum. A locking fitting portion is disposed on the tail end of the power cord and adapted to the locking portion. Furthermore, a rotating sleeve is rotatably sleeved on the connection end, an inner wall of the rotating sleeve has a driving part, and the rotating sleeve rotates to drive the driving part to further drive the locking portion to rotate, thereby locking the locking portion or unlocking the locking portion from the locking fitting portion. The power cord can be disassembled and assembled only by rotating the rotating sleeve, and the operation is convenient, and the structure is simple.

  • Patent number: 9642434
    Abstract: A touch-screen hairdryer includes a touch screen and a control circuit, the touch screen is connected with the control circuit and arranged for receiving a touch signal from a user and then transmitting it to the control circuit, and the control circuit includes a wind speed adjusting circuit and a power adjusting circuit which are silicon controlled circuits arranged for adjusting wind speed and power according to the touch signal respectively. In comparison with the prior art, since the wind speed or power is adjusted by the silicon controlled rectifiers according to the touch signals inputted, thus a higher safety is obtained, and moreover the service life of the silicon controlled rectifiers is longer than the mechanical switch significantly.
