Abstract
The utility model provides an environmental protection magnetic flashlight, comprising a sealed waterproof casing and a slidable permanent magnet in the casing, a multi-layer coil, a rectifier element, a magnetic switch, a storage capacitor and a luminous body; wherein, the slidable permanent magnet is arranged in the multi-layer coil and is capable of reciprocating motion inside the coil; the induced current produced by the motion charges the capacitor through the rectifier element, and then illuminates the luminous body through the magnetic switches to achieve the lighting purposes. The utility model has the advantages of simple structure, convenient and reliable operation, waterproof performance, and no environmental pollution because battery is not needed.
Description
Technical field
The utility model relates to a kind of environmental protection lighting device, particularly a kind of environmental protection magnetic force flashlight.
Background technology
In daily life, flashlight is a kind of indispensable lighting device.When especially being engaged in car steering, outdoor sports, outdoor exercises, particularly meet under accident or the natural calamity situation, flashlight has more become convenient emergent illuminations.But the flashlight that present people use always is normally by common batteries or chargeable storage battery power supply; but because these flashlights can not waterproof; and the frequent situation about burning out of luminescent device incandescent lamp bulb; when emergent the use; provisional dead battery or bulb usually can take place to be damaged; make troubles to illumination, and old and useless battery etc. pollutes to environment again.
The utility model content
The purpose of this utility model provides a kind of environmental protection magnetic force flashlight, and whole device is sealed in the firm shell, not only waterproof but also be not afraid of and fall.
The utility model is achieved in that a kind of environmental protection magnetic force flashlight, comprise the slidably permanent magnet in waterproof sealing shell and the shell, lattice coil, rectifier cell, magnetic switch, energy-storage capacitor and illuminator, it is characterized in that slidably permanent magnet is arranged in the lattice coil, and can be reciprocating in coil.The sound is sent at collision coil two ends when preventing that permanent magnet from moving back and forth, as the lattice coil two ends of permanent magnet motion conduit slidably little magnetic sheet being housed respectively.
Described lattice coil is connected with rectifier cell, and the output of rectifier cell is connected with energy-storage capacitor, and energy-storage capacitor is connected with illuminator by magnetic switch.Illuminator adopts the super brightness semiconductor light-emitting-diode.
The utility model is simple in structure, and is easy to use and reliable, waterproof, owing to do not need to use battery, then free from environmental pollution.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model circuit theory diagrams;
1 waterproof sealing shell, 2 is permanent magnet, 3 lattice coils, 4 rectifier cells, 5 magnetic switch, 6 energy-storage capacitors, 7 illuminators, 8 magnetic sheets, 9 conduits slidably
The specific embodiment
As shown in the figure, the utility model comprises slidably permanent magnet 2, lattice coil 3, rectifier cell 4, magnetic switch 5, energy-storage capacitor 6 and the illuminator 7 in waterproof sealing shell 1 and the shell, it is characterized in that slidably permanent magnet 2 is arranged in the lattice coil 3, and can be reciprocating in coil.The sound is sent at collision lattice coil 3 two ends when preventing that permanent magnet 2 from moving back and forth, as lattice coil 3 two ends of permanent magnet 2 motion conduits 9 slidably little magnetic sheet 8 being housed respectively.
Described lattice coil 3 is connected with rectifier cell 4, and the output of rectifier cell 4 is connected with energy-storage capacitor 6, and energy-storage capacitor 6 is connected with illuminator 7 by magnetic switch 5.Illuminator 7 adopts the super brightness semiconductor light-emitting-diode.
Sketch operation principle of the present utility model below in conjunction with accompanying drawing: the device that the utility model produces electric energy is by slidably permanent magnet 2 is reciprocating in lattice coil 3, because the magnetic line of force of permanent magnet cuts the lead in the lattice coil 3 at the volley, make and produce induced-current in the lead, direction is that the electric current that changes becomes unidirectional current through rectifier cell, and charges to energy-storage capacitor.When needs use, open magnetic switch 5, then energy-storage capacitor 6 sends the illumination light to the power supply of super brightness semiconductor light-emitting-diode.Before using earlier with hand with this flashlight with direction of principal axis whipping more than 10 seconds, permanent magnet 2 is reciprocating in lattice coil 3, then the electric energy that stored of energy-storage capacitor 6 just can be lighted the time of light emitting diode about 10 a few minutes.
Claims (4)
1, a kind of environmental protection magnetic force flashlight, comprise the slidably permanent magnet in waterproof sealing shell and the shell, lattice coil, rectifier cell, magnetic switch, energy-storage capacitor and illuminator is characterized in that slidably permanent magnet is arranged in the lattice coil, and can be reciprocating in coil.
2, environmental protection magnetic force flashlight according to claim 1 is characterized in that described lattice coil is connected with rectifier cell, and the output of rectifier cell is connected with energy-storage capacitor, and energy-storage capacitor is connected with illuminator by magnetic switch.
