Abstract: A hand squeeze generator includes a carrying body, a lever, an elastic member to return the crank to its original position, a gear transmission unit, and a generation motor driven by the gear transmission unit. The lever drives the gear transmission unit and the gear transmission unit drives the generation motor through a clutch gear. The hand squeeze generator may be installed on an electric appliance or connected to an electric appliance, alternatively, be used to charge a rechargeable battery. The generator is driven to generate electricity or to recharge a battery. Therefore, no external power source is required when there is no sufficient electric power supply or the battery runs down.

Abstract: A hand crank generator includes a crank, a gear transmission, and a generation motor driven by the gear transmission. The crank and the gear transmission are coupled to each other. A clutch gear is coupled between the crank and the gear transmission. The crank is manually driven to further drive the gear transmission, and the generation motor is driven to generate electric current through the clutch gear. When the cranking stops, the clutch gear disengages from a motor gear disposed on the generation motor. A weighted wheel continues to revolve under inertia for a while to drive the generation motor to keep on generating electric current, so that the purpose of saving manual efforts can be achieved.

The lever drives the gear transmission unit and the gear transmission unit drives the generation motor through a clutch gear. The present invention may be installed on an electric appliance or connected to an electric appliance, alternatively, be used to charge a rechargeable battery. When the electric power is not enough or the battery is going to run down, it is not necessary to connect an external power source. The present invention is driven to generate electricity or to recharge a battery. The present invention is favorable for environmental protection, cost-effective, easy for production, and convenient in use.

Abstract: A hand crank generator includes crank, gear transmission, and generation motor driven by the gear transmission. The crank and the gear transmission are coupled to each other. A clutch gear is coupled to where between the crank and the gear transmission. The crank is manually driven to further drive the gear transmission, and the generation motor is driven to generate electric current through the clutch gear. When the cranking stops, the clutch gear disengages from a motor gear disposed on the generation motor. A weighted wheel continues to revolve under inertia to drive the generation motor to keep on generating electric current without continuing to crank; therefore, achieving the purpose of saving manual efforts.

Abstract: A wheel with sound and light effects includes a fork for supporting a wheel, a magnetic element, and a plurality of lamps. A plurality of lamps are installed at the spoke of a wheel. Each lamp is installed with a magnetic receiving element made by winding a coil. Each magnetic receiving element is connected to a capacitor and a light emitting element. Two outer sides of the rim each are installed with a magnetic element and are locked to the fork. Thereby, a rotating wheel may light up in the whole cycle as it rotates.

Abstract: An activating device for light-emitting wheel comprises a wheel, a sound and light generating circuit, a plurality of light emitting elements and a plurality of conductive wires. The wheel has a hub at the center of the wheel, a plurality of spokes radially arranged around the hub and a rim arranged around the outer contour of the plurality of spokes. An interspace chamber is formed between two adjacent spokes. The sound and light generating circuit is arranged within one of the interspace chambers. The sound and light generating circuit has a housing case, two conductive plates, an activating element and a top cover on the housing case. The two conductive plates are of the same structure and have slantingly bent bottom portions. The two conductive plates are such mounted on the housing case that a predetermined separation is kept between the two slantingly bent bottom portions thereof.
