Embodiment

Your auditor effect of understanding creation characteristic of the present utility model, content and advantage and can reaching for the benefit of, now with the utility model conjunction with figs., and be described in detail as follows with the expression-form of embodiment, and it is wherein employed graphic, its purport only is the usefulness of signal and aid illustration book, may not be true ratio after the utility model enforcement and precisely configuration, so should not understand, the interest field of limitation the utility model in reality enforcement with regard to appended graphic ratio and configuration relation, close chat earlier bright.

Please cooperate referring to shown in Figure 2, the utility model proposes a kind of radio frequency induction coil, it can comprise in a preferred implementation: coiling part 10, a wafer cell 20 and a line of induction 30.

Aforesaid coiling part 10 is the solid column of an elongated, and this coiling part 10 or can be a plurality of solid block and combine, and this coiling part 10 or to can be the tool permeability magnetic material made, it is made for example to can be iron material matter, and this coiling part 10 recessed respectively coiling groove 11 that is provided with on the wall of two respective side thereon.

Aforesaid wafer cell 20 is one can be subjected to the less radio-frequency function wafer of current drives, and its correspondence is located on this coiling part 10, and for example can recline is arranged on the end face of this coiling part 10, and this wafer cell 20 has two contacts 21.
