Description

Flashlight with electric generation by itself

Technical field

The utility model relates to a kind of flashlight with electric generation by itself.

Background technology

Flashlight kind in the market is numerous and diverse, varied, and style constantly updates, and except that the flashlight of general use dry cell, also has the flashlight of multiple rechargeable battery.Utilize grip to make luminous flashlight of torch or the like but also there is utilization to hold torch through the generating of transmission device drive TRT.These flashlights have because of using dry cell, not only uneconomical, main is the battery pollution environment.In a single day the rechargeable battery flashlight runs into power failure or power free situation can not be used.Also exist situations such as device complexity, serious wear and hold power generation flashlight, damage easily.At existing problem in the above-mentioned prior art, a kind of novel flashlight of research and design, existing problem is very necessary in the prior art thereby overcome.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel flashlight with electric generation by itself of research and design.This flashlight changes past people to be used dry cell or utilizes rechargeable battery to make the luminous traditional approach of torch, but pump in the middle of utilizing the online volume of permanent magnetism iron core, make coil of wire cutting magnetic line produce induced potential, after rectification, give light emitting diode, play the effect of illumination.Flashlight with electric generation by itself described in the utility model is made of inner core and urceolus, the outer wall of inner core twines the coil of wire, the cylindrical magnet iron core is housed in the inner core can be prolonged inner core and pump, two of the coil of wire terminates to the interchange end of the rectifier bridge on the printed substrate, the DC terminal of rectifier bridge is received on the both positive and negative polarity of electric capacity on the printed substrate and chargeable electric button cell, switch on the urceolus is received light emitting diode on the battery, makes lumination of light emitting diode, realizes illumination purposes.Inner core described in the utility model and urceolus can be made cylindrical tube or rectangle cylindrical shell.Permanent magnetism iron core in the inner core is also corresponding to be made cylindrical or rectangle.Flashlight with electric generation by itself change described in the utility model used dry cell or rechargeable battery to make the luminous method of flashlight in the past, but utilize people in using the torch process, torch to be rocked, thereby pump in the middle of making the online volume of permanent magnetism iron core in the torch inner core, make coil of wire cutting magnetic line produce induced potential, this kinetic energy that rocks is converted into electric energy makes torch luminous.The utlity model has novel structure, simple structure, economical and practical, energy savings, characteristics such as health is pollution-free, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

Description of drawings

The utility model has two accompanying drawings, wherein

Accompanying drawing 1 is the flashlight with electric generation by itself structural representation

Accompanying drawing 2 is flashlight with electric generation by itself electrical schematic diagrams

Among the figure: 1, light emitting diode 2, condenser 3, printed substrate 4, the coil of wire 5, permanent magnetism iron core 6, inner core 7, urceolus 8, chargeable button cell 9, switch 10, electric capacity 11, rectifier bridge

The specific embodiment

Specific embodiment of the utility model as shown in Figure 1, inside at the urceolus 7 of flashlight is with inner core 6, permanent magnetism iron core 5 is housed in the inner core 6, twining the coil of wire 4 on the outer wall of inner core 6, the interchange end of the rectifier bridge 11 of printed substrate 3 is received in two terminations of the coil of wire 4, and the DC terminal of rectifier bridge 11 is received respectively on the both positive and negative polarity of electric capacity 10 on the printed substrate 3 and chargeable button cell 8.Switch 9 on the urceolus 7 is received light emitting diode 1 on the both positive and negative polarity of chargeable button cell 8 and is made light emitting diode 1 luminous, realizes illumination purposes.The purpose of condenser 2 is to make light more concentrated.The utility model in use, earlier with rock before and after the torch several down, permanent magnetism iron core 5 front-rear reciprocation movements in the inner core 6 make the coil of wire 4 cutting magnetic lines produce induced potential, send for after rectifier bridge 11 rectifications electric capacity 10 and chargeable button cell 8.After pressing, switch 9 make light emitting diode 1 connect power supply and luminous.The effect of chargeable button cell 8 is that electric energy is in store, and still can make light emitting diode 1 that electroluminescence is arranged when not rocking flashlight.Electric capacity 10 is electrolytic capacitors, and its effect is to prevent the overtension after the rectification and damage chargeable button cell 8 and light emitting diode 1.

Claims (2)
