However, since the fan needs to be connected to the power supply through the power cord, if the power cord is too short, it is not easy to reach the socket, and if the power cord is too long, it will be suspended and exposed on the wall. Longer power cords are not only unsightly, but also may fall to the ground, increasing the risk of tripping.

[0004] Generally, the user will wind the longer power cord on the shell of the fan, but since the power cord wound on the shell is also in a suspended state, it cannot be well stored. CONTENT OF THE INVENTION

One end of the power cord is connected to the motor in the fan frame, and the other end passes through the winding shaft and the winding disc from the inside of the fan frame and is connected to the plug; part of the power cord is located in the winding cavity, and the winding disc has a winding hole for the power cord to pass through.

[0008] Preferably, a torsional spring is arranged between the winding disc and the winding shaft.

[0009] Preferably, a tensioning device for tensioning the power cord in the winding cavity is arranged in the winding cavity, and a tensioning end of the tensioning device abuts against the power cord.

[0010] Preferably, the tensioning device comprises a tensioning frame fixed to the circumferential inner wall of the winding disc, a tensioning member slidingly arranged on the tensioning frame, and a tension spring arranged between the tensioning member and the tensioning frame; the tension spring has a tendency to force the tensioning member to move towards the power cord, and one end of the tensioning member towards the power cord is a tensioning end.

[0011] Preferably, the tensioning member is arranged in an arc shape towards one end of the power cord.

[0012] Preferably, a fixing frame is arranged on the fan frame, and the fixing frame is fixed to a wall surface.

[0013] Preferably, the fixing frame is provided with a sliding groove, and the fan frame is fixed with a sliding block matched with the sliding groove.

[0014] In summary, the utility model has the following beneficial technical effects:

[0015] When the power cord is too long, the winding disc is rotated to push the power cord to wind the power cord on the winding shaft, and the winding shaft is located in the winding cavity, so that the winding disc can shield the excess power cord, which can not only achieve an aesthetic effect, but also reduce the problem of tripping caused by the excess power cord.

[0023] The application discloses a power cord winding fixing mechanism of a wall-mounted fan.

[0024] The power cord winding fixing mechanism of the wall-mounted fan comprises a fan frame 1 and a fixing frame 3, the fixing frame 3 is fixed on a wall surface through bolts, the fan frame 1 is provided with a sliding groove 31, the fan frame 1 is fixed with a sliding block 32, the sliding block 32 is matched with the sliding groove 31, the sliding block 32 of the fan frame 1 is inserted into the sliding groove 31 after the fixing frame 3 is installed on the wall surface, and the fan frame 1 can slide relative to the fixing frame 3. Thus, the wind direction of the fan can be adjusted.

[0025] The fan frame 1 is provided with a winding shaft 11 and a winding disc 12, the winding shaft 11 is hollow and communicates with the inside of the fan frame 1, the winding disc 12 is rotationally arranged in the winding shaft 11, and a winding cavity 13 is formed between the winding disc 12 and the winding shaft 11. One end of the power cord 4 is connected with a motor in the fan frame 1, the other end of the power cord 4 enters the inside of the fan frame 1 from the inside of the fan frame 1, then sequentially passes through the winding shaft 11 from the inside of the winding shaft 11 and enters the winding cavity 13, and then passes through the winding disc 12 from the inside of the winding cavity 13 and extends to the outside, wherein the power cord 4 outside is connected with a plug, and the plug can be inserted into a socket.

[0026] The winding disc 12 is provided with a winding hole 14 for the power cord 4 to pass through. A torsion spring 15 is arranged between the winding disc 12 and the winding shaft 11. When the power cord 4 is too long, the torsion spring 15 drives the winding disc 12 to rotate, so that the side wall of the winding hole 14 pushes the power cord 4, and the power cord 4 can be wound on the winding shaft 11.

[0027] The winding cavity 13 is provided with a tensioning device 2 for tensioning the power cord 4 in the winding cavity 13, and a tensioning end of the tensioning device 2 abuts against the power cord 4. The tensioning force of the tensioning device 2 is smaller than the torsion force of the torsion spring 15 driving the winding disc 12 to rotate. Under the action of the tensioning device 2, the power cord 4 can be better wound on the winding shaft 11.

[0028] The tensioning device 2 comprises a tensioning frame 21, a tensioning piece 22 and a tension spring 23. The tensioning frame 21 is fixed to the circumferential inner wall of the winding disc 12, the tensioning piece 22 is slidingly arranged on the tensioning frame 21, and the two ends of the tension spring 23 are connected with the tensioning piece 22 and the tensioning frame 21 respectively.

The one end of the tensioning piece 22 towards the power cord 4 is arranged in an arc shape. Under the action of the tension spring 23, the tensioning end of the tensioning piece 22 abuts against the power cord 4, and the tensioning device 2 is located close to the winding hole 14.

[0029] In the application, the two tension devices 2 are oppositely arranged, and the two tension members 22 are close to each other and can clamp the power cord 4.

[0030] The implementation principle of the embodiment is that when the power cord 4 is too long, the power cord 4 is wound on the fan frame 1, then under the action of the coil spring of the winding disc 12, the winding disc 12 rotates, and the winding disc 12 can allow part of the power cord 4 to enter the winding cavity 13 and be wound on the winding shaft 11. The winding direction of the power cord 4 wound on the fan frame 1 needs to be the same as the rotation direction of the winding disc 12.
