The present invention is directed to overcoming the above problems of the prior art and providing a dual power supply type hand-held electric fan.

The technical scheme is as follows:

a double-power-supply type handheld electric fan comprises a deformable fan handle, a fan net, a built-in small motor, fan blades, a power line, a USB interface, a mobile phone charging interface, a small screw, an interface converter, a rotating shaft, a power transmission strip, a converter connecting strip, a clamping hole and clamping teeth, wherein the power line is positioned inside the deformable fan handle and is connected with the built-in small motor and the USB interface, so that the fan blades can normally rotate when the fan is electrified; the fan net can effectively protect the fan blades and avoid damage; the deformable fan handle supports the small fan, and the direction can be adjusted randomly according to the use; the small screw is used for fixing the fan net; the USB interface can be connected with any electric appliance with a USB socket, and the fan rotates when the electric appliance is switched on; the mobile phone charging interface realizes that the small fan is directly connected to the mobile phone charging interface by the interface converter, the converter connecting strip, the rotating shaft, the clamping hole and the clamping teeth, and provides a power supply for the small fan.

When people need to use a double-power-supply type handheld electric fan, the USB interface can be plugged into the socket through the power supply transmission strip, the built-in small motor is communicated through the power line, the rotation of the fan blades is realized, and the deformable fan handle can be twisted at will when the direction needs to be adjusted; when people need to use a double-power-supply type handheld electric fan on a mobile phone, a charging interface of the mobile phone can be connected with a USB interface through an interface converter, a converter connecting strip, a rotating shaft, a clamping hole and a clamping tooth, so that the double-power-supply type handheld electric fan can work on the mobile phone; when people need to maintain or clean the internal structure of the double-power-supply handheld electric fan, the fan screen can be opened through the small screw to maintain and clean.

Has the advantages that:

the invention solves the problems that the existing USB fan is huge in size and cannot be used in a multifunctional way, and brings great convenience to the study and life of people.

Drawings

The invention is further illustrated with reference to the following figures and examples.

(the same parts in the figures are numbered identically)

Fig. 1 is a schematic diagram of an overall structure of a dual-power-supply type handheld electric fan.

Fig. 2 is a schematic diagram of a USB interface structure of a dual-power handheld electric fan.

The mobile phone comprises a deformable fan handle 1, a fan screen 2, a built-in small motor 3, fan blades 4, a power line 5, a USB interface 6, a mobile phone charging interface 7, a small screw 8, an interface converter 9, a rotating shaft 10, a power supply transmission strip 11, a converter connecting strip 12, a clamping hole 13 and a clamping tooth 14.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-2, the portable fan comprises a deformable fan handle 1, a fan net 2, a built-in small motor 3, fan blades 4, a power line 5, a USB interface 6, a mobile phone charging interface 7, a small screw 8, an interface converter 9, a rotating shaft 10, a power transmission strip 11, a converter connecting strip 12, a clamping hole 13 and a clamping tooth 14.
