Abstract

The utility model relates to an electric torch without a battery, which comprises a cylinder body and a driving handle, wherein the driving handle is connected to a self-electric generating device which is arranged in the cylinder body. The self-electric generating device is electrically connected with a rectifying energy storing device. The utility model is characterized in that an output end of the self-electric generating device is connected with a switch which is respectively electrically connected with an LED and the rectifying energy storing device; one side on the back surface of the top end of a gear rack of the driving handle is provided with a groove which is matched with a lock catch handle on the outside of the cylinder body. The utility model has the advantages of automatic electrical energy providing for luminous lighting, power supply storage, good lighting brightness, long service life of luminous elements, light and handy volume and convenient carrying.

Description

A kind of flashlight

Technical field

The utility model relates to a kind of lighting apparatus, specifically be meant a kind of without battery, the electric energy luminous lighting can be provided voluntarily, can store power supply, illumination light good brightness, a kind of flashlight of being convenient for carrying.

Background technology

The power supply of the flashlight of traditional type is nothing more than using battery or dry cell, there is certain defective in the flashlight of this use battery, the electric weight of battery is limited service time, need often to change, the old and useless battery that changes is recycled and badly then can be polluted environment, especially the soil that people are depended on for existence and the pollution of water quality.In order to overcome the above-mentioned defective that the battery flashlight exists, people have designed a kind of flashlight of self power generation at present, and its principle is kinetic energy to be converted into mechanical energy produce electric energy again, has replaced traditional battery flashlight with this.The flashlight design novel structure of this structure, economical and practical, energy savings can not brought pollution to environment.But it also also has not enough very perfect one side, the self-generating device of the flashlight with electric generation by itself of interrelated data record at present mostly is the hand acting or utilizes the acting of hand wobble flashlight collision type, throw light on while generating electricity, what have does not also have an energy storage device, the light-emitting component of its use all is to adopt incandescent lamp in addition, the brightness of illumination is not very bright, and its range is also not far, and the service life of incandescent lamp is short simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the background technology, provide a kind of without battery, the electric energy luminous lighting can be provided voluntarily, can store power supply, the flashlight of illumination light good brightness, light-emitting component long service life, a kind of novel designs of being convenient for carrying.

The purpose of this utility model is achieved by the following technical solution: a kind of flashlight, comprise cylindrical shell and driving handle, described driving handle is connected in the self-generating device that is provided with in the cylindrical shell, self-generating device is electrically connected the rectification energy storage device, it is characterized in that being electrically connected switch at the output of self-generating device, described switch is electrically connected light-emitting component and rectification energy storage device respectively: the back side one side on the tooth bar top of described driving handle is provided with groove, and groove cooperates with the lock catch shank in the cylindrical shell outside.

Light-emitting component described in the such scheme is a light emitting diode, and light emitting diode places in the through hole on the reflector.

Rectification energy storage device described in the such scheme places cylinder chamber indoor.

Lock catch shank described in the such scheme cooperates with the mouth of wearing of cylindrical shell bottom one side, and the projection that the inboard end of its lock catch shank stretches in the cylindrical shell places in the back side groove on driving handle tooth bar top; Raised line that described lock catch shank both sides are provided with and cylindrical shell are worn a mouthful interior groove fit.

Aforesaid the utility model; need not use or change battery; be to drive the self-generating device generating by the body fixed handle; thereby user's manual capacity regulator is changed into electric energy realization illumination by the technical program; therefore the utlity model has easy to use; economical and practical, as to save energy and protect environment plurality of advantages.The led lighting brightness range that adopts in the technical program is long, and service life is also long; Its handle bar is buckled in the cylindrical shell when also having the lock catch shank of design to make driving handle on the flashlight not work, and is not fragile, is easy to carry.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the generalized section of the utility model one embodiment;

Fig. 2 is the utility model one example structure exploded perspective view.

The specific embodiment

With reference to a kind of flashlight shown in the accompanying drawing 1～2, comprise cylindrical shell and driving handle, described driving handle is connected in the self-generating device that is provided with in the cylindrical shell, self-generating device is electrically connected rectification energy storage device 3, output at self-generating device is electrically connected driving switch 1, and described driving switch is electrically connected light-emitting component 2 and rectification energy storage device 3 respectively; The back side one side on the tooth bar top of described driving handle 4 is provided with groove 41, and groove 41 cooperates with the lock catch shank 5 in the cylindrical shell outside; Described light-emitting component 2 is a superluminescent diode, and light emitting diode places in the through hole 7 on the reflector 6; Described rectification energy storage device 3 places in the cylindrical shell chamber 8; Described lock catch shank 5 cooperates with the mouth 9 of wearing of cylindrical shell bottom one side, and the projection 51 that its lock catch shank 5 inboard ends stretch in the cylindrical shell places in the back side groove 41 on driving handle 4 tooth bar tops; The raised line 52 that described lock catch shank 5 both sides are provided with is worn a mouthful interior groove 10 with cylindrical shell and is cooperated.

When the utility model uses, hold flashlight shell and push that driving handle drives that the self-generating device running produces electric energy and luminously by being defeated by light-emitting component after the energy storage of rectification energy storage device produced illumination, when flashlight does not use, the handle bar that lock catch shank is fastened driving handle makes flashlight be more convenient for carrying in the cylindrical shell of flashlight.
