Abstract
The utility model relates to a charger for an electric torch. The utility model is characterized in that the charger for an electric torch comprises a battery box, and a charged battery, a circuit board, a voltage transformer, a high-voltage elastic piece, a clip and a negative electrode guide piece are successively arranged in the battery box. A high-voltage plug is arranged outside the battery box, and the high-voltage elastic piece is connected to a primary winding set of the voltage transformer. A secondary winding set of the voltage transformer is connected to the charged battery, and the high-voltage plug is externally connected with an alternating current power supply. Due to the adoption of technical scheme, the charged battery is arranged in the battery box and thus the charged battery can replace a dry battery and is arranged in an electric torch for lighting. The charged battery can also be taken out and is inserted in an ac 220V power supply to be directly charged, and the consumption of dry batteries is reduced. The utility model has the advantages of economy and flexibility, and environmental pollution can be avoided.
Description
Technical field
The utility model relates to charger, especially refers to a kind of charger that is used for flashlight.
Background technology
Existing flashlight is equipped with some joint dry cells in stack shell, battery bottom (negative pole) contact flashlight spring, and flashlight small electric bulb negative pole is pressed onto by cups and dishes and contacts battery cathode on the stack shell guide card; The small electric bulb positive pole touches anode by the courage seat guide card of flashlight.
The flashlight of said structure, small electric bulb brightness reduces deepening gradually with cell voltage, and the dry cell consume significant.Dry cell after using simultaneously can produce pollution to environment.
The utility model content
The purpose of this utility model is to provide a kind of Charger for electric torch of alternative dry cell, has reduced dry cell consumption, has more economy, flexibility, has also avoided the pollution to environment.
A kind of charger that is used for flashlight provided by the utility model, it is characterized in that, it comprises battery case, set gradually rechargeable battery in battery case, wiring board, transformer, high pressure shell fragment, clip and negative pole guide card, outside battery case, be provided with high-voltage plug, this high pressure shell fragment is connected to the elementary winding of transformer, this Secondary winding of transformer is connected to rechargeable battery, this high-voltage plug external AC power supply.
At the above-mentioned charger that is used for flashlight, high-voltage plug is to be connected on the described battery case with rotary way.
At the above-mentioned charger that is used for flashlight, the stack shell of the flashlight that the profile of battery case is used for it is complementary.
At the above-mentioned charger that is used for flashlight, battery case is to have loam cake and lower cover to fasten to form.
At the above-mentioned charger that is used for flashlight, rechargeable battery adopts Ni-MH battery.
Owing to adopted above-mentioned technical solution, promptly in battery case, adorn rechargeable battery, both can replace dry cell to put into flashlight lighting and use, can take out insertion alternating current 220V power supply again directly charges, reduced dry cell consumption, had more economy, flexibility, also avoided pollution environment.
Description of drawings
Fig. 1 is the assembling schematic diagram that the utility model is used for flashlight.
Fig. 2 is the structural representation of the utility model charger.
Embodiment
Shown in Fig. 1～2, the utility model is used for the charger 100 of flashlight, comprises battery case loam cake 1, lower cover 2, clip 3, high-voltage plug 4, negative pole guide card 5, high pressure shell fragment 6, wiring board 7, self-tapping screw 8, rechargeable battery 9 and transformer 10.Wherein: transformer 10 elementary winding leads are welded on two high pressure shell fragments 6, and transformer 10 secondary winding lead-in wire is welded in wiring board rectifying circuit input, and the low-voltage AC of transformer 10 outputs gives rechargeable battery 9 chargings after rectification.The positive pole of charger is the positive contact of rechargeable battery 9, and the negative pole of charger is the negative pole guide card, links to each other with the negative pole of rechargeable battery 9.Red light was bright when AC low-tension had electricity; Battery case upper and lower covers 1,2 is fastening by stamping screw 8 after the snap close fastening.
High-voltage plug on the battery case 4 is cocked, and it is promptly chargeable to insert the 220V AC Power supply socket, and charging finishes plug is equalized, and battery case is put into stack shell and promptly be can be used to illumination.
In sum, with charging battery cartridge as the power supply of flashlight, because of rechargeable battery has life-span that recycles more than 500 times, than having more economy with dry cell.Adopt rechargeable battery stable because of its voltage as power supply, small electric bulb can remain at brighter state.Rechargeable battery adopts Ni-MH battery, and memory does not have more superiority and environmental protection more than nickel-cadmium cell.In addition, original flashlight structure is constant, has just increased charging battery cartridge, makes flashlight become both available rechargeable battery by original single use dry cell, and also available dry cell is more convenient flexible.Charge power supply adopts the transformer step-down rectifier, and high-pressure side is equipped with fuse, and is more safe and reliable.
