Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Accompanying drawing is a structural representation of the present utility model, and as shown in the figure: a kind of light current control forceful electric power electrical appliance device comprises power supply 1, step-down transformer 2, rectifier diode 3, rheotrope 4, electromagnetism box body 12, is fixedly installed on elastomer 5 and solenoid 6 in the electromagnetism box body 12; Be fixed with electromagnet 62 corresponding permanent magnets 7 on the elastomer 5 with solenoid 6; Be fixed with left electrode 8 on the elastomer 5, be fixed with on the solenoid 6 and left electrode 8 corresponding right electrodes 9; Distance between permanent magnet 7 and the electromagnet 62 is greater than the distance between left electrode 8 and the right electrode 9; The electromagnetic wire 61 of described power supply 1, step-down transformer 2, rectifier diode 3, rheotrope 4 and solenoid 6 is connected successively; Described power supply 1 is electrically connected with left electrode 8, and right electrode 9 is electrically connected with forceful electric power electrical appliance 10 to be used.All adopt light current line 11 to be electrically connected between step-down transformer 2 and the rectifier diode 3, between rectifier diode 3 and the rheotrope 4 and between rheotrope 4 and the electromagnetic wire 61; All adopt the forceful electric power line to be connected between power supply 1 and the step-down transformer 2, between power supply 1 and the left electrode 8 and between right electrode 9 and the forceful electric power electrical appliance 10.
