Definitions

  • the present invention relates to a device for an electric fan, particularly to a power saving and energy storage device able to recycle energy from an electric fan.
  • the electric fan In summer, the electric fan is the most frequently used household electric device.
  • the conventional electric fan technology does not pay attention to recycling mechanical energy but only addresses using electricity to drive electric fans. Owing to the global warming awareness and fast energy price inflation, people are highly concerned about how to save energy and reduce carbon emission, and many organizations encourage renewable energy. If there is a device able to recycle the energy of the electric fans, energy consumption and expenditure should be obviously reduced.
  • the present invention proposes a power saving and energy storage device for an electric fan to overcome the abovementioned problems.
  • the primary objective of the present invention is to provide a power saving and energy storage device for an electric fan, which recycles the mechanical energy of the blades of the electric fans to generate electric energy and stores the electric energy, whereby the mechanical energy of the fan blades is recycled to obtain regenerated electric energy.
  • Another objective of the present invention is to provide a power saving and energy storage device for an electric fan, wherein the electric fan is swiveled to provide air flows for all the users around the electric fan.
  • the present invention proposes a power saving and energy storage device for an electric fan, which comprises an electric fan, a power generator module, and an electric storage unit arranged inside the electric fan.
  • the electric fan includes a DC (Direct Current) motor.
  • the DC motor has a first shaft penetrating the DC motor. One end of the first shaft is connected with blades.
  • the DC motor drives the first shaft to rotate the blades.
  • the other end of the first shaft has an installation member where the power generator module is mounted.
  • the power generator module includes a three-phase electric generation coil and a magnet ring.
  • the three-phase electric generation coil is penetrated by the installation member and attached to the sidewall of the DC motor.
  • the magnet ring is arranged in the first shaft and surrounds the three-phase electric generation coil.
  • the magnet ring While the first shaft rotates, the magnet ring also rotates. Thus, the magnetic field of the magnet ring induces an alternating electromotive force in the three-phase electric generation coil. Then, the electromotive force is sent to the electric storage unit inside the electric fan and stored as electric energy therein.
  • the power saving and energy storage device for an electric fan of the present invention comprises an electric fan 10, a power generator module 18, and an electric storage unit 28 arranged inside the electric fan 10.
  • the electric fan 10 includes a DC (Direct Current) motor 12.
  • the DC motor 12 has a first shaft 14 penetrating the DC motor 12.
  • One end of the first shaft 14 is connected with blades 16 of the electric fan 10.
  • the DC motor 12 drives the first shaft 14 to rotate the blades 16.
  • a protection cover 44 covers the blades 16 and protects the user from being hit by the blades 16.
  • the other end of the first shaft 14 has an installation member 142 where the power generator module 18 is mounted.
  • the power generator module 18 includes a three-phase electric generation coil 22 and a magnet ring 24.
  • the three-phase electric generation coil 22 is penetrated by the installation member 142 and attached to the sidewall of the DC motor 12 lest the three-phase electric generation coil 22 rotate with the first shaft 14.
  • the magnet ring 24 surrounds the three-phase electric generation coil 22.
  • a magnet ring seat 25 is arranged in the first shaft 14 and fixes the magnet ring 24 to the first shaft 14, whereby the magnet ring 24 rotates together with the first shaft 14. While the first shaft 14 rotates, the magnet ring 24 also rotates, and the magnetic field of the magnet ring 24 induces an alternating electromotive force in the three-phase electric generation coil 22.
  • the electric storage unit 28 is electrically connected with a rectifier 30.
  • the rectifier 30 is further electrically connected with the three-phase electric generation coil 22, receiving the alternating electromotive force and outputting a DC electric energy to the electric storage unit 28.
  • the electric storage unit 28 is electrically connected with a sensor 32 which can measure the quantity of electricity in the electric storage unit 28.
  • an additional power generator module 18 is further arranged in the other end of the shaft 14, i.e. the end where the blades 14 are mounted, to increase the efficiency of power generation.
  • the mechanical structure and circuit layout of the second embodiment are the same as the first embodiment and will not repeat herein.
  • the electric fan 10 is in form of a box fan. In one embodiment, the electric fan 10 is used to drive a wind power generator.
  • the electric fan 10 is exemplified by a standing fan and thus further comprises a base 34, a pole 36 standing on the base 34, and a synchronous DC motor 38.
  • the synchronous DC motor 38 is mounted on the top of the pole 36 via a second shaft 50 that is fixed to the pole 36.
  • the synchronous motor 38 is also coupled to the DC motor 12 via a coupling element 52. While the synchronous DC motor 38 rotates, it intends to rotate the second shaft 50. However, the second shaft 50 is fixed to the pole 36.
  • the synchronous DC motor 38 itself and the DC motor 12 that is coupled to the synchronous DC motor 38 rotate. Thereby, the DC motor 12 swivels 360 degrees, and the blades 10 sends air flows to all the users around the electric fan 10.
  • the electric fan 10 includes a power supply socket 42 electrically connected with the electric storage unit 28, whereby the electric storage unit 28 can send electric energy to the power supply socket 42.
  • the power supply socket 42 is a USB (Universal Serial Bus) socket.
  • the power supply socket 42 can cooperate with different types of USB adaptors to charge or supply power to different types of electric devices.
  • the power supply socket 42 is arranged on the electric fan 10.
  • the power supply socket 42 may be in other forms.
  • the power supply socket 42, together with the insulated wire hangs outside the electric fan 10, cooperating with different types of USB adaptors to charge or supply power to different types of electric devices.
  • the present invention further comprises a switching device 48.
  • the switching device 48 is electrically connected with the DC motor 12, the synchronous DC motor 38, the commercial power supply 40 and the electric storage unit 28, switching the electric connection of the DC motor 12 between the commercial power supply 40 and the electric storage unit 28.
  • the switching device 48 can switch the DC motor 12 to be powered by the commercial power supply 40 or the electric storage unit 28.
  • the user can use the switching device 48 to switch the DC motor 12 to be disconnected from the commercial power supply 40 and directly powered by the electric storage unit 28. While the electric storage unit 28 that is powering the DC motor 12 is insufficient to drive the DC motor 12, the user can use the switching device 48 to switch the DC motor 12 to be powered by the commercial power supply 40 again.
  • the switching device 48 can also switch the synchronous DC motor 38 in the same way.
  • the user can use the switching device 48 to switch the synchronous DC motor 38 to be disconnected from the commercial power supply 40 and powered by the electric storage unit 28. While the electric storage unit 28 that is powering the synchronous DC motor 38 is insufficient to drive the synchronous DC motor 38, the user can use the switching device 48 to switch the synchronous DC motor 38 to be powered by the commercial power supply 40 again.
  • the three-phase electric generation coil 22 and the magnet ring 24 convert the mechanical energy output by the DC motor 12 into electric energy.
  • the electric storage unit 28 stores the electric energy and supplies the stored electric energy to the intended devices. Thereby, energy is recycled, and the objective of environmental protection is achieved.
  • the present invention can effectively utilize the mechanical energy rotating the blades to generate electric energy and store the electric energy.
  • the electric fan of the present invention is swiveled to provide air flows for all the users around the electric fan.
