In addition, since the hard wire, rope or other pendant is generally connected to the outer periphery (non-centerline position) of the fan body, the angle between the fan body and the neck-hanging connector is easily changed with the movement of the body, thereby changing the optimal blowing angle and affecting the user experience. Summary of the invention

The characteristic is that a deformation channel is arranged on the fan body which runs through both sides of its periphery and passes through its central axis, and the deformation channel is used to clamp the neck hanging piece.

[0006] The purpose of the present invention can also be solved by the following technical measures:

[0007] As a more specific solution, the width between the left and right sides of the deformation channel is greater than the width of the neck hanging piece, so that the neck hanging piece can be swung and adjusted within the width range of the deformation channel.

[0008] As a further solution, the deformation channel is flat, which can have a larger contact area with the neck hanging piece and fix it more securely.

[0009] As a further solution, the fan body includes a battery compartment and a fan host, the battery compartment is connected to the bottom of the fan host, the battery is arranged in the battery compartment, the air inlet and the air outlet are arranged on the fan host, and the deformation channel is arranged between the battery compartment and the fan host. The battery compartment and the fan host are movably matched to realize the size adjustment of the deformation channel.

[0010] As a further first solution, the battery compartment and the fan host are coordinated in lifting and lowering activities, and a locking buckle is provided at a low position where the battery compartment approaches the fan host for locking the battery compartment and the fan host in a close position.

[0011] As a further second solution, the battery compartment and the fan host are elastically opened and closed to cooperate with each other so that the deformation channel forms a clamp.

[0012] As a further third scheme, the fan body includes a battery compartment and a fan host, the battery compartment is connected to the bottom of the fan host, the battery is arranged in the battery compartment, the air inlet and the air outlet are arranged on the fan host, and an elastic part is provided in the deformation channel, and the size of the deformation channel is adjusted by changing the deformation amount of the elastic part.

[0013] As a further solution, the battery compartment is also provided with a control circuit board, a charging socket and a control button. The fan host is provided with a motor and a wind wheel that are transmission-connected to each other. The air inlet and air outlet are respectively arranged on the end face and the periphery of the fan host. The motor and the battery are respectively electrically connected to the control circuit board.

Moreover, the deformation channel passes through the interior of the fan body and is closer to its center of gravity. The relative position of the fan body and the neck-hanging part is not easily changed, thereby improving the comfort of use.

[0018] (2) The deformation amount of the deformation channel of this neck-hanging small fan can be changed by means of inclined surface matching, or by means of elastic deformation. It is easy to operate, reliable to clamp, and not easy to loosen.
