Abstract

The utility model discloses an electric torch with hand-operated electricity generation, which is used for night illumination. An electricity generator, a gear box, an LED group, a cover, a super capacitor, a diode, and a rocking handle are clamped and arranged inside two shell sheets; one output wire of the electricity generator is electrically connected with the cathode of the diode, and the anode of the diode is electrically connected with the anode of the super capacitor and a switch, and the other end of the switch is electrically connected with an anode of the LED group, and the other output wire of the electricity generator is electrically connected with the cathodes of the super capacitor and the LED group. The LED group is a high-power light source consisting of nine Phi 5mm LEDs which are arranged in three groups with three LEDs in each group. When shaking the handle by hand, electricity generated by the electricity generator can be quickly and efficiently used for charging the super capacitor or directly lightening the LED group.

Description

Hand torch

Affiliated technical field

The utility model relates to a kind of night light, especially can rapidly and efficiently charge, high-power hand torch.

Background technology

The structure of known hand torch is by having clamped generator, gear-box, poultry electrical equipment, wiring board, bulb, crank handle etc. in two shells at present, this torch does not have usage charges, advantage such as easy to use, but also have charging rate and drawback such as efficient is low, power is little.

Summary of the invention

Have charging rate and efficient is low, power is little deficiency in order to overcome existing hand torch, the utility model provides a kind of hand torch, and it not only has charging effect fast and efficiently, and power output is big.

The technical scheme that the utility model technical solution problem is adopted is: clamped generator, gear-box, LED group, cover, ultracapacitor, diode, circuit board, crank handle etc. in two shells, generator one output line is electrically connected with diode cathode, positive pole is electrically connected with ultracapacitor positive pole and switch, the switch other end is electrically connected with the LED group is anodal, another output line of generator and super group capacitor are connected with the negative electricity of LED group, LED organize by 9 φ 5mmLED be arranged in three one group totally three groups form.When electricity that the crank handle generator sends finishes up to the charging of current potential equal capacitance device on the very fast positive and negative pole plate of flow of charge being gone into super electrical equipment of the direct current after the rectification, the size of capacitor institute charge volume is directly proportional with the capacitance size of capacitor, ultracapacitor has especially big capacitance, thereby reach charging effect is fast and efficiently arranged not only, and the big purpose of power output.

The beneficial effects of the utility model are: have that charging effect and power output are big fast and efficiently, because of the ultracapacitor charge and discharge reach 100,000 times, so the life-span is long.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the vertical section structural map of hand torch embodiment.

Among the figure 1, LED group 2, electricity bowl 3, circuit board 4, switch 5, gear-box 6, crank handle 7, left shell 8, generator 9, ultracapacitor 10, diode 11, cover 12, right casing

The specific embodiment

In Fig. 1, generator 8 one output lines are connected with diode 10 negative electricities, and positive pole is electrically connected with ultracapacitor 9 positive switch 4, switch 4 other ends and LED group 1 anodal the electrical connection, and generator 8 other end output lines are organized 1 negative electricity with ultracapacitor 9 with LED and are connected.LED group 1 by 9 φ 5mmLED be arranged in three one group totally three groups form.Generator 8 gives ultracapacitor 9 chargings when switch 4 disconnects, and during opposite switch 4 paths, generator 8 or ultracapacitor 9 go to light LED group 1.

In Fig. 2,3,4 illustrated embodiments, generator 8, gear 5, LED group 1, cover 11 and circuit board 3 are fixed on the left shell 7, and ultracapacitor 9 switches 4 and diode 10 are fixed on the circuit board 3, being connected and exposing of the axle of crank handle 6 and gear-box 5, right casing 12 interfixes with left shell 7.Gear-box 5 is formed step-up gear by 4 grades of gear trains.Generator 8 fast rotational generating when hand fixed handle 6.
