Solenoid 6 setting-ins are gone into the intracavity of half pot core 5, and half pot core 5 is that the garden is annular, and magnetic core 5 is made by soft magnetic ferrite; Temperature controller 8 is mounted on the back of half pot core 5; Framework 4 is merged by resin and far-infrared ceramic powder material and magnetic core 5 and solenoid 6 is solidified togather; The outstanding card in surface is a radiation dish 7.Formed the magnetic thermal energy radiation head 2 that to launch far infrared heat and pulsed magnetic field jointly.Because contact area is big, thermal resistance is little, can fully absorb and conduct heat, both can make pulsed magnetic field produce strong electromagnetic induction in the human body depths, can make the far infrared heat act on the human body shallow-layer again, and dual combination can be received better curative effect.

Mains transformer 11 and control circuit board are installed in the console controller 1, power supply is after mains transformer 11 blood pressure lowerings, behind resistance R 1R2, the capacitor C 1 trigger tube U2 control bidirectional thyristor U1 AC chopping by the RC circuit, be added to respectively on the solenoid 6 through positive and negative half-wave gating bridge U3, in two and half pot type magnetic circuits, produce the energy composite energy radiation of pulsed magnetic field and thermal field respectively.

Pulse generating circuit operation principle of the present utility model is: control circuit board is installed in the console controller 1, after the energized, by mains transformer 11 TC just, low-voltage AC after the blood pressure lowering is given through resistance R 2R3 and is triggered capacitor C 1 charging, when making the current potential of C1 be increased to the breakdown voltage of two-way trigger tube U2 with the AC sine wave voltage, the electric charge of C1 is promptly by the control utmost point discharge of trigger tube U2 to bidirectional thyristor U1, trigger current makes the two-way trigger tube conducting, make chopper current be added on load-solenoid through positive and negative half-wave gating bridge, at the skip before of chopper current along producing precipitous magnetic field impulse ripple, when the alternating current zero crossing, IGCT turn-offs voluntarily, when arriving, repeats next half-wave above-mentioned RC circuit charging trigger process again, thereby make the positive and negative half-wave behind the AC chopping be added on the solenoid of two electromagnetic radiation heads respectively by the gating bridge, form DC pulse magnetic field and thermal field, act on the purpose that human body depths lesions position reaches the treatment disease.

The utility model has the advantages that: volume is little, and is in light weight, simple and reliable, portably use conveniently, cost is low, and purposes is wide, and curative effect is fast, no pain has no side effect, owing to be the biradial head, be applicable to the needs of different situations, can be single or two positions use simultaneously, can select polar configurations to use, be a kind of economical and practical domestic physical therapeutical instrument.
