Spiral type self power generation flashlight

Abstract

A spiral type self power generation flashlight comprises a light tube and a light cap connected with the light tube. Light sources are arranged in the light cap, a first spiral groove which is hollow is formed in the outer periphery of the light tube, a rotatable magnetic tube is arranged in the light tube, and a second spiral groove which is not hollow is formed in the outer periphery of the magnetic tube and arranged opposite to the first spiral groove. The first spiral groove and the second spiral groove are the same in rotating direction, shape and size. A coil conductor is arranged in the magnetic tube, and a sleeve is arranged on the light tube in a sleeved mode and can move back and forth in the axial direction of the light tube. At least on clamping pin is arranged on the outer periphery of the sleeve, penetrates through the first spiral groove and can move back and forth in the radial direction of the sleeve. A controller and a rechargeable battery are arranged in the light tube, wherein the controller is electrically connected with the coil conductor, and the rechargeable battery is electrically connected with the controller. The spiral sliding structure is adopted for generating power, and the sleeve can drive the magnetic tube to rotate to generate the power in the process of sliding upwards and downwards along the axis of the light tube, so that power generation efficiency is remarkably enhanced, a large amount of electric energy can be rapidly generated and stored in the rechargeable battery, and then the lighting time of the light sources is prolonged.

Description

technical field [0001] The invention belongs to the field of lamps, and in particular relates to a spiral self-generating flashlight. Background technique [0002] At present, there are all kinds of self-generating flashlights on the market, such as the common hand-cranking, hand-pressing, and hand-swinging, etc., but these self-generating flashlights have low power generation efficiency, insufficient power generation, and limited lighting time. . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a spiral self-generating flashlight with high power generation efficiency and sufficient power generation. [0004] The present invention is realized in this way, a spiral self-generating flashlight includes a lamp holder and a lamp holder connected with the lamp holder, the lamp holder is provided with a light source, and the outer periphery of the lamp holder is provided with a hollow first spiral groove , a rotatable magnetic cylinder is arr...
