CN2481951Y - Electricity self-generating multipurpose electric torch - Google Patents

Abstract

The utility model relates to a self-generating multipurpose torch, which consists of a miniature electric generator, a torch body, a hand pressing rod and a gear pair. The axle end of the miniature electric generator arranged in the torch body is fixed and connected with a driving gear, and gear racks meshed with the driving gear and a direction change gear are processed on the hand pressing rod. A battery does not need to be purchased from outside or an external power does not need to be connected, thus saving the expense; the structure is simple; the operation is convenient.

Description

Flashlight is used in self power generation more

The utility model relates to a kind of self power generation and uses flashlight more, mainly as the usefulness of flashlight and electric shaver, also the electricity that sends can be supplied with the usefulness of radio, earphone and little power consumption household electrical appliance etc.

Prior art is to adopt battery or external power power supply.Its weak point is: need to increase the expense of purchasing battery or using power supply; Battery is lost also contaminated environment.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of self power generation without battery or external power to use flashlight more.

This practical purpose can reach by following measure: the utility model is made up of microgenerator, cylindrical shell, hand bar and gear pair, be loaded on the fixedly connected driven wheel of microgenerator axle head in the cylindrical shell, process tooth bar on the hand bar with driven wheel, change gear engagement.

Flywheel is equipped with in driven wheel and change gear central authorities.

There is spring hand bar lower end.

Be connected with torch cover or shaver lid before the cylindrical shell.

The drawing of accompanying drawing is described as follows:

Fig. 1 always schemes for partial cutaway of the present utility model;

Fig. 2 is the right side view of Fig. 1, only represents the engaging structure between hand bar and gear among the figure.

The accompanying drawing piece number is represented:

1, microgenerator 2, cylindrical shell 3, hand bar 4, torch cover

5, bulb 6, condenser 7, goggle sheet 8, axle

9, driven wheel 10, driven wheel 11, change gear 12, tooth bar

13, box 14, spring 15, axle sleeve 16, blade

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 and Fig. 2 represent structure of the present utility model, mainly are made up of microgenerator 1, cylindrical shell 2, hand bar 3 and gear pair, and microgenerator is a prior art.Microgenerator is housed in the cylindrical shell, and the barrel front end torch cover 4 that has been threaded has bulb 5, condenser 6 and goggle sheet 7 in the flashlight.The microgenerator front end is equipped with battery and charger (not expression on the figure), and these all are prior aries.The electricity that microgenerator sends fills and is stored in the battery, when needing to use flashlight lighting, need only press button and get final product according to existing flashlight using method.

The rotation of microgenerator is driven by hand bar that is loaded on its rear end and gear pair.Gear pair comprises driven wheel 9, change gear 11 and driven wheel 10.The axle 8 of microgenerator is fixedly connected with driven wheel 9 and driven wheel 10, process tooth bar 12 on the hand bar 3, the width of tooth bar is bigger, energy while and driven wheel 9,10 engagements, the flywheel that driven wheel and change gear central authorities are equipped with the energy forward rotation and oppositely skid.There is the spring 14 that is loaded on box 13 hand bar bottom, and the hand bar has axle sleeve 15 outside the top and the bottom.

During use, hand presses the hand bar downwards, and tooth bar drives driven wheel 9 and 10 simultaneously.Driven wheel 9 drives 8 rotations of micro generation arbor with generating, and driven wheel 10 and the change gear 11 of this moment skid.After treating that the hand bar is depressed into lower dead center and stops descending and openhanded opening, under the spring force effect, the backhaul that makes progress of hand bar, at this moment, driven wheel 9 skids, change gear 11 rotation to be driving the equidirectional continuation rotation of driven wheel 10 along axle, and to reach the hand bar when descending and up, axle remains same direction and rotates with continuous generating.Like this, when staying at home idle or see TV, can ceaselessly intermittently press the hand bar, constantly generating is to store energy in the battery, for application.

When needs repack electric shaver into, the torch cover is unloaded, change razor head, battery-operated razor head inner blade 16 rotations are to shave.

The utility model contrast prior art has following advantage:

Without the outsourcing battery or connect external power, but cost saving; Structure is simpler; Easy to use.
