Description

An electric fan that can generate electricity

technical field

The utility model relates to the technical field of devices with power generation function, in particular to an electric fan capable of power generation.

Background technique

Electric fan is a very common household appliance nowadays, and its utilization rate and utilization efficiency are not as high as before. This is because the use effect of household air conditioners is obviously better, and it is also popular now. At present, in many occasions, electric fans have been replaced by air conditioners. Therefore, for the existing electric fan, how to use or utilize it outside the scope of heat reduction and ventilation? Many people are thinking about this issue.

Wind energy is a clean, safe, and renewable green energy. The use of wind energy has no pollution to the environment, no damage to the ecology, and has good environmental and ecological benefits. It is of great significance to the sustainable development of human society. Wind power generation using wind energy is a project that uses natural resources to generate electricity, which has emerged with the development of environmental protection and has been increasingly advocated. It meets the requirements of sustainable social development. At present, many wind power generation devices are under construction in many areas of our country, such as seasides, grasslands, and mountain passes. So, can electric fans be used? Nowadays, almost every household has an electric fan, and the frequency of using the fan in summer is a lot, but once the summer is over, the electric fan will be put away and used again in the next summer. So, can electric fans be able to play a role in spring, summer, autumn and winter?

Utility model content

The purpose of this utility model is to promote the concept of energy saving and environmental protection, and to provide an electric fan capable of generating electricity by using green energy. A power generation device and a battery pack are installed on the traditional electric fan, and the blades of the electric fan are used to drive the power generation device to generate electricity. Then store the generated electric energy in the storage battery. When needed, the storage battery can charge small electrical appliances, such as mobile phones, mp3, psp, small LED lights with low power, etc., which saves trouble and saves electricity.

In order to achieve the above object, the technical scheme that the utility model takes is:

An electric fan capable of generating electricity, comprising fan blades, a motor and a base, is characterized in that it also includes a generator, a fan controller and a battery pack; the generator and the motor are mounted on the same shaft, but the two Can not work at the same time, that is, when the generator is working, the motor does not work; the fan controller and the battery pack are arranged in the base, and a USB charging interface is provided on the base; the fan controller and the fan blades and Connect the generator and use the fan controller to control the rotation of the fan blades. The fan blades are connected to the generator through the shaft, one end of the generator is connected to the fan controller, the other end of the generator is connected to the battery pack, and the other end of the battery pack is connected to the USB for charging. Interface connection; the electricity generated by the generator is transported and stored in the battery pack through the wire, and the small electrical appliances are charged through the USB charging interface.

The battery pack is provided with a power display device, which can display charging, battery power and charging completion.

The power display device displays externally through the through hole on the base.

The working principle of the utility model is: the fan blades of the electric fan are driven by natural wind to rotate, the fan blades drive the shaft to rotate to make the generator work, the electricity generated by the generator is stored in the storage battery pack, and can charge small electrical appliances through the USB charging interface.

The positive effect of an alarm device for preventing overheating of the electric blanket of the utility model is:

(1) Add new functions to the traditional electric fan and expand the range of use of the electric fan;

(2) There is an additional small power generation device, and it can be used conveniently;

(3) It only needs to modify the structure of the existing electric fan, which has a prospect of application.

Detailed ways

A specific embodiment of an electric fan capable of generating electricity of the present utility model is given below in conjunction with the accompanying drawings, but the implementation of the present utility model is not limited to the following embodiments.

Referring to accompanying drawing 1, a kind of electric fan that can generate electricity includes fan blade 1, motor and base 2, and these structural parts can adopt existing parts; The generator 5 and the motor are installed on the same shaft, but the two cannot work at the same time, that is, when the generator 5 works, the motor does not work. The fan controller 4 and the storage battery pack 6 are arranged in the base 2, and a USB charging interface 3 is arranged on the base 2 (outside).

The battery pack 6 is provided with a power display device, which can display charging, battery power and charging completion. The power display device is displayed externally through the through hole on the base 2 .

Referring to accompanying drawing 2, described fan controller 4 is connected with fan blade 1 and generator 5 and controls the rotation of fan blade 1 with fan controller 4, fan blade 1 is connected with generator 5 by shaft, and one end of generator 5 is connected with generator 5. The fan controller 4 is connected, the other end of the generator 5 is connected with the battery pack 6 , and the other end of the battery pack 6 is connected with the USB charging interface 3 . The electricity that fan blade 1 drives generator 5 to send is transported to storage battery pack 6 through wires through the shaft, and these stored electric energy can charge small electrical appliances through the USB charging interface 3 on the outside of base 2 . The electrical appliances include (but are not limited to) mobile phones, MP3 players, psps, small LED lamps with low power, and the like.

The electric fan capable of generating electricity of the present utility model is placed in the place with wind inside or outside the family, and the condition of high-rise or well-ventilated residence may be better, but safety must be paid attention to. The blower fan controller 4 of the electric fan capable of generating electricity is modulated in "power generation mode", so that the fan blade 1, the shaft, and the generator 5 just enter the power generation state under the blowing of natural wind (the speed of the fan blade 1 at the tuyere should be at least up to 200 rpm). After a period of power generation, the storage battery pack 6 can charge small electrical appliances through the USB charging interface 3, because the voltage output by the storage battery pack 6 is stable, so it does not need to be rectified.
