Detailed ways

The following descriptions are only the preferred embodiments of the present invention, and the protection scope is not limited to this embodiment. All technical solutions that belong to the idea of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

As shown in Figures 1 to 3, a conical bag air duct with a skeleton includes an air duct body 1, and the air duct body 1 is conical. The air duct body 1 is made of fabric. The fabric is a soft material, and the inner diameter of the air duct body 1 can be changed at will. When the inner diameter of the air duct body 1 needs to be reduced, there is no need to do the diameter reduction treatment, which makes the use of the air duct body 1 more convenient. .

One end of the air duct body 1 is fixedly provided with a connecting section 3, and the connecting section 3 is provided with a fixing device. One end of the connecting section 3 is sleeved on one end of the external fan, and then the connecting section 3 and the fan are fixed by a fixing device. When the fan is started, the wind generated by the fan will enter into the air duct body 1, and the air duct body 1 can directionally guide the wind and send the air to the required position.

The fixing device includes a tightening strap 11 and a tightening buckle 12 , and the tightening buckle 12 is located at one end of the tightening strap 11 and is fixedly connected with the tightening strap 11 .
