The working principle is as follows: when the current between the first conducting wire 4 and the second conducting wire 12 is too large, the current passing through the memory alloy wire 10 at the connection part is also increased, so that the memory alloy wire 10 is heated rapidly and deformed and contracted, and drives the first contact piece 11 to move downwards, then the spiral first conducting wire 4 outside the sleeve 3 does not generate a magnetic field any more, and further does not attract the iron ring 6, then the iron ring 6 and the sliding rod 9 move upwards under the elastic force of the first spring 7, the first contact piece 11 and the second contact piece 13 move towards opposite directions simultaneously, the connection between the first conducting wire 4 and the second conducting wire 12 can be disconnected in time, thereby achieving the purpose of disconnection, when the first spring 7 drives the sliding rod 9 to move upwards, the first sliding rod 9 can extrude the liquid storage bag 14 inside the sliding chute 8, and further extrude the electrolyte inside the liquid storage bag 14 into the liquid storage tank 16, and realize the electrical connection between the two contacts 17, then the circuit is conducted and the buzzer body 15 is started, so as to prompt an operator to overhaul the circuit in time, after the magnetic field generated by the first lead 4 disappears after the circuit is broken, the magnet 26 moves upwards under the elastic force of the second spring 29, and the clamping rod 28 is pulled out of the clamping groove 27, then the elastic force of the coil spring 23 in the circular cavity 20 drives the fixed disc 22 and the rotating rod 21 to rotate, and then the synchronous belt 24 drives the fan 32 at the upper end of the rotating shaft 31 to rotate, so as to ventilate and radiate the inside of the shell 1, so as to reduce the time for the memory alloy wire 10 to recover to a normal shape, further the circuit can be conducted in time after the overhaul is completed, when the circuit between the first lead 4 and the second lead 12 is normally conducted, the magnetic field generated by the spiral first lead 4 outside the sleeve 3 and the magnet 26 repel each other, so that the clamping rod 28 can be stably inserted into the clamping groove 27 in the fixed disc 22, in order to keep holding power to coil spring 23, rethread pressure dynamic pressure pole 30 moves down in order to drive hoop 6, make first contact 11 can with second contact 13 electric connection, in order to realize switching on of circuit, after the electric current through first wire 4 is too big, spiral first wire 4 also can send a large amount of heats, the liquid alcohol in the stock solution chamber 19 can be heated and become gaseous and absorb a large amount of heats simultaneously this moment, and then accomplish the heat dissipation with pivoted fan 32 cooperation, further reduce the circuit and overhaul the time that the back switched on circuit needs of accomplishing.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
