Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
Fig. 2 is the fundamental diagram of the specific embodiment of the invention.
Embodiment
Referring to Fig. 1, the present invention includes control box 1, be arranged on the temperature knob on the box face, asymptote variable torque axle 10, contact switch 7, multiply netting twine 5, binding post 3, temperature knob and asymptote variable torque axle 10 closely cooperate, by the rotary temperature knob asymptote can be rotated with regard to axis of torque 10, between described contact switch 7 and asymptote variable torque axle, drive system is arranged, transmit asymptote variable torque axle and rotate the machine driving that produces, described drive system comprises supporting bridge 11, temperature-sensitive bimetal leaf 2, armature plate 8 and permanent magnet 6; One end of supporting bridge 11 is connected with control box, and with this tie point as the strong point, supporting bridge can be done corresponding swing, the other end of supporting bridge 11 is fixedlyed connected with an end of temperature-sensitive bimetal leaf 2, temperature-sensitive bimetal leaf 2 is a U type structure, its other end is fixedly connected with armature plate 8, and armature plate 8 is provided with the contact 4 of switch contacts, and the opposite side that is positioned at armature plate 8 with respect to asymptote variable torque axle 10 is provided with permanent magnet 6 and switch contacts seat 12.
Referring to Fig. 2, the operation principle of drive system of the present invention is: asymptote variable torque axle 10 closely cooperates with box surface temperature knob, turning knob, asymptote variable torque axle 10 promotes U type temperature-sensitive bimetal leaf 2 assemblies and moves, and apply support force F1, under the condition of removing permanent magnet 6, asymptote variable torque axle promotes U type temperature-sensitive bimetal leaf 2 assemblies and moves freely, permanent magnet 6 is arranged on armature plate 8 outside certain positions, magnetic attraction F2 attracts armature plate 8, at this moment the support force F1 in the drive system, U type temperature-sensitive bimetal leaf elastic force F3, expansive force F4, magnetic attraction F2 seeks dynamic balance.
Set up support force F1, when ambient temperature constant, the drive system dynamic balance, that is,
∑F1+∑F2+∑F3+∑F4＝0
F1-support force, F2-magnetic attraction, F3-temperature-sensitive bimetal leaf self elastic force, F4-temperature-sensitive bimetal leaf expansive force in the formula.This moment, armature plate 8 was in the dynamic balance critical surface, and drive system is stable.
F1 is constant when support force, and when ambient temperature descended, temperature-sensitive bimetal leaf expansive force F4 reduced, and temperature-sensitive bimetal leaf 2 moves to permanent magnet 6 directions, and armature plate 8 reduces with permanent magnet 6 distances, magnetic attraction F2 to armature plate with index acceleration adhesive (F2=MB * S/d
2Wherein M-constant, S-metallic area, B-magnetic flux density, the distance of d-armature plate 8 and permanent magnet 6), contact switch is connected, electricity heating in the load; When the ambient temperature rising, temperature-sensitive bimetal leaf 2 expansive force F4 increase, and armature plate is thrown off F2 suction, gets back to critical surface, and contact switch disconnects, and the load outage stops to heat.
