Abstract

The utility model relates to a hand press flashlight which is used for lighting at night. The utility model has the technical proposal that two shells are internally provided with a handle rack, a gear unit, a little gear with pawl, a power generator, an end board, a LED unit, a capacitor, a switch and a diode; a wire package is arranged between two column iron cores; the stators which are riveted with each other through a pipe and the rotors which consists of a permanent magnetic element and a flywheel are connected through a shaft to form a permanent magnetic power generator; the output wire of the generator is connected in parallel with the capacitor through a diode; and the capacitor is connected in parallel with the LED unit through the switch. The utility model has the advantages of large output power, five LED lighting and being capable of being relayed for using after being charged.

Description

The hand torch

Affiliated technical field

The utility model relates to a kind of torch of night illumination, especially can light 5 LEDs and the luminous hand torch of charging back time-delay.

Background technology

The structure of at present known hand torch is by having clamped travelling gear, generator, bulb etc. in two shells, and this torch is without battery, and is pollution-free, advantages such as no cost of use, but there are drawbacks such as generator efficiency is low, power output is little in it.

Summary of the invention

Have the little deficiency of power output in order to overcome the hand torch, the utility model provides a kind of hand torch, and it can not only be lighted the also chargeable back time-delay of 5 LEDs and use.

The technical scheme that the utility model technical solution problem is adopted is: clamp pinion, generator, end plate, LED group, capacitor, diode, switch of handle tooth bar, gear train, band ratchet etc. in two shells, by the two columnar iron cores in front and back, therebetween one line bag, with pipe with their rivetings stator together and the rotor that is linked to be by permanent magnet and flywheel, with the magneto that axle conspires to create them, the generator output line is in parallel with capacitor through diode, capacitor is in parallel with the LED group through switch.The generator of this structure can obtain more extremely right, when the synchronous generator load is inductance, the armature-reaction size of generator, main flux weakens what and change the size of refusing and generator output current big or small proportional, this power generator electrode is to more, work as rotating speed, when main flux is constant, can improve generator output frequency and voltage, under the power output same case, can reduce output current, the generator armature reaction, main flux weakens and commentaries on classics is refused, improve generator efficiency and power output, capacitor is store electrical energy rapidly and efficiently, thereby reaches the purpose that can light 5 LEDs and charging time-delay use.

The beneficial effects of the utility model are: can light 5 LEDs and charging time-delay and use, high and capacitor charge and discharge reach 100,000 times because of this generator efficiency, so advantages such as little, the life-span length of volume in addition.

The specific embodiment

In Fig. 1, diode 5 negative poles are electrically connected with generator one end, and positive pole is electrically connected with capacitor 4 positive poles and switch 6 one ends, switch 6 other ends and LED group 2 anodal electrical connections, the generator other end and capacitor 4 are connected with the negative electricity of LED group 2, and LED organizes 2 and is fixed on the printed panel by 5 LEDs and forms.Generator is supplied with capacitor 4 chargings when switch 6 disconnects, and when switch 6 was connected, generator or capacitor 4 power supplies were organized 2 luminous to LED.

In Fig. 2,3,4 illustrated embodiments, axle 11, stator 14, gear train 12, capacitor 4, diode 5, switch 6, pin 7 are gone here and there spring 8 and handle tooth bar 13 together, all be fixed on the left shell 16, rotor 9 is linked to be by permanent magnet 9-2 and flywheel 9-1 and is with ratchet gear 10 to be contained on the axle 11, end plate 15 is connected with the other end of gear train 12 pins 7 with axle 11, and it is fixing in left shell 16, lid 1 is the transparent body, the electricity bowl 3 that LED group 2 is housed is packed into to cover and is installed in a left side in 1 hole together,

right casing

16,17, two shells interfix.Clamp a line bag 14-2 in the middle of 14-4 unshakable in one's determination, the 14-3 of stator 14 by the short long two grid-like pole pieces of cylindrical shape in front and back, went here and there the mesopore of two 14-4 unshakable in one's determination, 14-3 and line bag 14-2 with pipe 14-1, form by the even cloth riveted joint of the pole piece of two iron cores, rotor 9 is linked to be magneto with stator 14 by axle 11.When hand fixed handle 13, rotor 9 rotations, permanent magnet 9-2 rotation in the middle of the pole piece of two 14-4 unshakable in one's determination, 14-3 produces alternating magnetic field, and the lead of magnetic force line cutting line bag 14-2 induces electromotive force.
