The beneficial effects of the utility model are: the utility model is used magnesium air cell as energy carrier, has light, simple in structure, cruising time is long, and the feature that " charging " time is short, when do not used, can outwell electrolyte, alleviate and carry weight, be particularly suitable for long-term field and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic cross-section of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As Fig. 1, shown in Fig. 2, the utility model comprises shell, LED lamp holder and magnesium air cell, described shell comprises cylindrical shell 1, be arranged on the bonnet with spring 89 of cylindrical shell 1 rear end and be arranged on the flashlight switch 10 on cylindrical shell 1 outer wall, the front end of cylindrical shell 1 and LED lamp holder join, LED lamp holder comprises a circuit control panel 14, lamp shell, lamp holder eyeglass 15 and LED lamp 12, circuit control panel 14 is arranged in lamp shell, 6 or 9 LED lamps 12 are installed on circuit control panel 14, the upper end of LED lamp 12 is provided with lamp holder eyeglass 15, lamp shell is provided with draw-in groove 11, described magnesium air cell comprises columniform metal fuel rod 7, columnar air electrode and electrolyte 6, metal fuel rod 7 is placed between the draw-in groove 11 of LED lamp holder and the spring 8 of bonnet 9 and is fixed in cylindrical shell 1 by draw-in groove 11 and spring 8, metal fuel rod 7 adopts magnesium metal bar, magnadure rod, one in magnesium-rare earth rod, it is cylindric that air electrode is, from the outer watertight composition 3 that is followed successively by toward in, current collector layers 4 and Catalytic Layer 5, air electrode with clamping plate 13, be fixed on the inwall of cylindrical shell 1 and with bonnet 9, LED lamp holder forms a closed cavity, electrolyte 6 is placed in described closed cavity, described electrolyte 6 is NaCl or MgCl
2deng neutral salt solution.The cylindrical shell 1 of flashlight, in the situation that not affecting structural strength, adopts hollow out, carves the mode such as mortise and produce a large amount of pores 2, is convenient to air contact with air electrode; Described bonnet 9 is provided with steam vent 16.
Operation principle of the present utility model is as follows: metal fuel rod 7 inserts in the draw-in groove 11 of LED lamp holder, tightens bonnet 9, and extrusion spring 8 reaches the object of fixing metal fuel rod 7.Air electrode is formed by watertight composition 2, current collector layers 3 and Catalytic Layer 4 compactings from outside to inside, while making cylindrical shell 1, by clamping plate 13, air electrode is permanently affixed to cylindrical shell 1 inner side, and seals by binding agent, prevents leakage.Air electrode contacts with air by the pore 2 on cylindrical shell 1.During perfusion electrolyte 6, electrolyte 6 is poured in flashlight, covered tightly bonnet 9.While opening switch 10, the electric energy input circuit control panel 14 of generation, by its current stabilization, rectification, exports electric energy to LED lamp 12, obtains stable illuminating effect.
When battery metal fuel rod 7 approach exhaustion, turn on bonnet 9, pour out electrolyte 6, change new metal fuel rod, pour into new electrolyte, battery can recover, and flashlight can recover rapidly normal illumination function, realizes the complete charging interval to be no more than five minutes.
