    COIL-TYPE ELECTROMAGNETIC INDUCTION CHARGING ELECTRICAL DEVICE FIELD OF THE INVENTION [0001] The present invention relates to an electronic device, and more particularly to a coil-type electromagnetic induction charging electrical device. BACKGROUND OF THE INVENTION [0002] Current small electric apparatus such as flashlight or shaver, etc, usually includes a chargeable structure, which applies a charging way via an electrical wire or by arranging a charging plug on the electric apparatus. Regarding the two charging ways above, however, the former needs a transformer arranged in the plug, which may take up bigger bulk and use many copper wires; the latter also needs a transformer arranged in the apparatus, which causes an increased bulk of the apparatus and needs many copper wires as well. By this token, the electric apparatus with the current charging way has disadvantages such as big bulk and high cost, etc. SUMMARY OF THE INVENTION [0003] One objective of the present invention is to provide a coil-type electromagnetic induction charging electrical device. [0004] To achieve the above-mentioned objective, the present invention provides a coil-type electromagnetic induction charging electrical device, which includes a power body and a charging body which are separate. The power body includes a first housing, a first charging circuit board arranged in the first housing, a chargeable battery, a load, and a first coil connected with the first charging circuit board. The charging body includes a second housing, a second charging circuit
    I
    board arranged in the second housing, a second coil connected with the second charging circuit board, and a charging plug mounted on the second housing. An annular sleeve-joint portion is formed on the second housing for sleeving the exterior of the first housing, the second coil is arranged in the annular sleeve-joint portion, and the first coil is exactly positioned in the second coil when the power body is connected with the charging body. [0005] The invention uses two coils to supply power to the battery of the electrical apparatus by electromagnetic induction, which can decrease the bulk of the coils needed by the charging unit, in turns and reduce the size of the product and the total amount of the copper wires, to reduce the cost of the products. BRIEF DESCRIPTION OF THE DRAWINGS [0006] Fig. 1 is an exploded perspective view of a power body according to an embodiment of the present invention; [0007] Fig. 2 is an exploded perspective view of a charging body according to an embodiment of the present invention; [0008] Fig. 3 is a perspective view of a combination of the power body of Fig. 1 and the charging body of Fig. 2; and [0009] Fig. 4 is a schematic view of the present invention. DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS [0010] A further explanation to the present invention will be described by combined with the detailed embodiments and the drawings. [0011] As shown in Figs. 1 to 3, the coil-type electromagnetic induction charging electrical device according to the present invention includes a power body 1 and a charging body 2 which are separate. The power body 1 includes a first housing 11, a first charging circuit board 12 arranged in the first housing 11, 2 chargeable batteries 13, a load 14, and a first coil 15 connected with the first charging circuit board 12. The charging body 2 includes a second housing 21, a second charging circuit board 22 arranged in the second housing 21, a second coil 23 connected with the second charging circuit board 22, and the second small magnetic rod 23 having a coil wound at periphery thereof, and a charging plug 24 mounted on the second housing 21. An annular sleeve-joint portion 211 is formed on the second housing 21 for sleeving the exterior of the first housing 11, and the second coil 23 is arranged in the annular sleeve-joint portion 211. When the power body 1 is connected with the charging body 2 in a sleeve mode, the first coil 15 is exactly positioned in the second coil. [0012] When the charging plug 24 is connected to the charging power source, the second charging circuit board 22 in the charging body 2 starts to work thereby the charging current passing through the second coil 23 and then generating induction current on the first coil 15 in the power body 1 due to electromagnetic induction, in turns, charging the chargeable battery 13 through the first charging circuit board 12, and finally supplying power to the load 14. By this token, The present invention uses two coils to supply power to the battery of the electrical device by means of electromagnetic induction, which decreases the bulk of the coils needed by the charging unit, in turns and reduces the size of the product and the total amount of the copper wires, so as to reduce the cost of the products. [0013] As shown in Fig. 4, in the present invention, a circuit in the second charging circuit board 22 which is served as a charging output terminal applies high-frequency induction output circuit, which can improve the frequency of the output terminal, and the first charging circuit board 12 served as a receiving terminal applies a receiving way of resonance, thereby achieving electromagnetic induction charging function. [0014] The power body 1 and the charging body 2 in the present invention 3 are separated structures, it's convenient to assemble together with each other when charging, and the charging body 2 could be disassembled from the power body 1 when charging is unnecessary, which may not affect the using of the power body 1. [0015] Of course, the embodiment shown in the figures is just a simple embodiment of the present invention. The load in the invention can be a small motor, a small light bulb, so as to form small electrical apparatus such as a small electric fan, a shaver, a desk light, a headlight, etc. Furthermore, the power body 1 further includes switches, indicating lights or other common parts which are omitted here. [0016] In conclusion, the size and bulk of the present invention is small, the manufacturing cost is low; the present invention can be formed as kinds of small or mini charging products or devices, which is very convenient. 4
