The operation principle of present embodiment is as follows:
The magnetic sensing temperature control device for electric heating container of present embodiment is fixed on heating container.Heat-conducting metal shell in magnetic sensing temp controller brake apparatus B has good thermo-contact with heating container.Steam port on the base A5 of magneto steam brake A is corresponding with the heating steam groove of container or steam hole.When an external force is applied, the first Hard Magnetic A1 in movable part A2 and the first soft magnetism A4 phase adhesive on base A5 is arranged in magneto steam brake A, the reed A3 that one end is fixed on base A5 and the other end is fixed on movable part movable part A2 is simultaneously compressed, lever A9 makes the pull bar B5 of magnetic sensing temp controller brake apparatus B move upward, until the second soft magnetism B2 in magnetic sensing temp controller brake apparatus B, 3rd Hard Magnetic B4 phase adhesive, the second spring B 3 in magnetic sensing temp controller brake apparatus B is compressed, lever A9 simultaneously in movable part A2 leaves and contacts with movable contact spring A10, the contact of movable contact spring A10 is dynamic with the contact on static contact A11 under the elastically-deformable effect of movable contact spring A10 to be contacted rapidly, the circuit turn-on of heating container, heater element in heating container is started working, arrive certain temperature, liquid boiling in heating container produces a large amount of steam, first soft magnetism A4 is come through steam oral instructions by the steam that steam groove or the steam pipe of the container that generates heat flow out and is heated, when the first soft magnetism A4 is heated to temperature (Curie-point temperature) that reach operating point, soft magnetism loses magnetic conductivity, lose the magnetic force of phase adhesive, under the effect of reed A3, make movable part A2 be upspring rapidly, above-mentioned movable contact spring A10 is separated rapidly with the contact of static contact A11, the circuit of heating container is disconnected, in addition, the elastic force that the repulsion produced between two Hard Magnetics when the first Hard Magnetic A1 is identical with the second Hard Magnetic A6 polarity and reed A3 produce can accelerate magneto steam brake and break the time, produces attracting magnetic force accelerate resetting time in magneto steam brake A when the first Hard Magnetic A1 is contrary with the second Hard Magnetic A6 polarity polarity between two Hard Magnetics.
When heating liquid in containers is not seldom or when having, now press magneto steam brake A, because of little liquid or do not have liquid in heating container, also a large amount of steam can not be produced during boiling, A is ineffective for magneto steam brake, heater element works on, the second soft magnetism B2 in magnetic sensing temp controller brake apparatus B is heated to certain temperature (Curie temperature), second soft magnetism B2 loses magnetic conductivity and loses attracting magnetic force, under the effect of the second spring B 3 in magnetic sensing temp controller brake apparatus B, pull bar B5 makes the lever A9 in magneto steam brake A in movable part A2 move downward, under the effect of reed A3, lever A9 makes movable contact spring on base A5 be separated rapidly with the contact on static contact, the circuit of heating container is disconnected, also make the soft magnetism in magneto steam brake be separated with Hard Magnetic simultaneously.
When the container that generates heat engages with power supply base, the Removable hook D18 mentioned in power down function device D contacts with the lower seat C200 in the electric coupler C on power supply base, by the Action of Gravity Field of generate heat container and liquid itself, the the first spring D17 mentioned in power down function device D is compressed, Removable hook D18 departs from another lever A9 of movable part A2 in magneto steam brake A, press this attemperating unit circuit ON of magneto steam brake, when the container that generates heat departs from power supply base, first spring D17 produces active force makes a lever A9 move downward by Removable hook D18, make the contact separation that the contact of lever A9 and movable contact spring in magneto steam brake A makes on movable contact spring and static contact, first Hard Magnetic A1 in magneto steam brake A is separated with the first soft magnetism A4, circuit in attemperating unit disconnects, when preventing electric heating vessel from putting back to power supply base, it is seriously overheated and damage electric heating vessel tool when in electric heating vessel, liquid repeatedly heats or do not have liquid in electric heating vessel.Again can only press magneto steam brake A, the just meeting conducting of whole circuit, heater element just can work.
Although describe embodiments of the present invention by reference to the accompanying drawings; but those skilled in the art can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection range described by claim of the present invention, all should within protection scope of the present invention.
