Abstract: An electric fan-type power generating device includes a housing receiving an electric motor that is supplied electricity from a chargeable battery to drive a first fan and a second fan to rotate at high speeds to thereby generate wind power close to a third fan mounted to a first generator. The first fan uses the wind power to drive the third fan in the housing. The third fan drives the first generator to generate electricity that is supplied to the chargeable battery. The second fan uses the wind power in the housing to drive a fourth fan to rotate. The fourth fan drives the second generator to generate electricity that is supplied to the chargeable battery. The chargeable battery recycles the electricity that supports operation of the electric motor for generating wind power. Furthermore, the wind power drives the first and second generators to continue generating electricity.

Abstract: A pneumatic ink-jet system is applied in an inkjet printer and uses a negative pressure generator, which is designed according to the Bernoulli's Theory, with a stable airflow in a certain speed to generated stable pressure inside at least one inkpot and at least one print head. Therefore, the at least one print head is kept in an appropriate wet state and the quality of printing is enhanced. Moreover, a top surface of the ink inside the at least one inkpot can be controlled to be higher than the at least one print head, so the pneumatic ink-jet system can be applied in a large format inkjet printer.

Abstract: An electric fan-type power generating device with low energy consumption includes a housing receiving an electric motor connected to a first fan. A generator is mounted in the housing and is connected to a second fan. The first and second fans are offset from each other. A power device includes a chargeable battery for supplying electricity to the electric motor that drives the first fan to generate wind power close to the second fan. Air flows around in a housing and generates turbulence to proceed with input and output of air, increasing the heat dissipating effect of the electric motor and the generator. Furthermore, the second fan drives the generator to generate electricity supplied to the chargeable battery. The chargeable battery recycles the electricity and supplies the electricity to the electric motor that operates to generate wind power. Furthermore, the wind energy drives the generator to continue generation of electricity.

Abstract: A power supply includes a housing receiving an electric motor, first and second fans, a generator, and a power device. The generator is concentrically mounted around the electric motor. When the electric motor is supplied with electricity from the power device and operates, a shaft of the electric motor drives the first fan to rotate, generating wind power close to the second fan. The second fan is rotated by the wind power in the housing and drives the second rotor and the second rotor seat to rotate. The first and second magnets create repulsive and attractive forces to provide inertia driving the second rotor seat, making the generator continuously supply electricity to the power device and the electric motor, thereby keeping the electric motor running to generate the wind power while the first fan continuously using the wind power to drive the second fan and the generator to generate electricity.
