The direct current of output is converted to the electric energy of predeterminated frequency and exports to the first coil 101, and first coil 101 is used for frequency conversion
The electric energy that conversion circuit provides is converted to electromagnetic field and launches.
The flashlight 2 includes 201 and second wireless charging device of rechargeable battery, and the second wireless charging device has second
Coil 202, the second coil 202 are arc-shaped, and the second coil 202 is used to be coupled with the electromagnetic field that first coil 101 generates
And carry out energy conversion and charge to rechargeable battery 201, the second wireless charging device further include rectification circuit and direct current-
DC converting circuit, the rectification circuit are used to the alternating current of second coil output being converted into direct current, and the direct current-
Then the voltage electricity that DC converting circuit is used for the direct current for exporting the rectification circuit is converted into predeterminated voltage to be chargeable
Battery 201 charges, wherein, the predeterminated voltage is equal to the voltage of rechargeable battery 201.
When the flashlight 2 is charged, flashlight 2 is lain in a horizontal plane on charging base 1, first coil 101 and second
Coil 202 is perfectly aligned or a part for first coil 101 is alignd with a part for the second coil 202, that is to say, that first
101 and second coil of coil, 202 perfectly aligned or section aligned, it is only perfectly aligned in 101 and second coil 202 of first coil
Or in the case of section aligned, the electromagnetic field that the second coil 202 could be generated with first coil 101 is coupled.
As shown in Fig. 5~Fig. 8, second coil 202 has multiple, and the plurality of second coil 202 is around flashlight 2
Central axes are circumferentially distributed, and the plurality of second coil 202 forms coil block, the arbitrary neighborhood of the coil block two second
In coil 202, a part for one of them the second coil 202 and a part for the second coil of other in which 202 are stacked mutually,
That is two 202 parts of the second coil of the arbitrary neighborhood of coil block are stacked, and there are two the coil blocks, wherein one
A coil block is nested on another coil block wherein, and the second coil 202 in two coil blocks staggers between each other
It sets, that is to say, that the second coil 202 in two coil blocks is not perfectly aligned, the second line in two coil blocks
Circle 202 is staggered around the central axes of flashlight 2, so so that the quantity of the second coil 202 is more, and the second coil 202
It closely arranges along the circumferencial direction of flashlight 2, in this way, being charged and flashlight is horizontal positioned to charging bottom in flashlight
When on seat 1, no matter flashlight around own axis how many angle, still has at least one second coil 202 and First Line
101 alignment of circle in this way, when flashlight 2 is placed on charging base 1, can not have to specially make flashlight around own axes
The angle for rotating to adjust flashlight can be that flashlight charges so that charge more convenient.
The flashlight 2 includes cylindrical case 203 made of nonmetallic materials, and rechargeable battery 201 is arranged on
In cylindrical case 203, rechargeable battery 201 is coaxially set with cylindrical case 203, and two coil blocks are respectively positioned on cylindrical case
