Description of the invention: [Technical field of the invention] The present invention relates to a circuit for dual temperature induction power-off (1), which is provided with a thermal induction tripping device and a dumpling guard structure in the circuit loop. Form two independent temperature-sensing power-off devices; when the circuit breaker is overheated or the ambient temperature is too high, the thermal induction trip can be used to remove the 'temporary power-off state of the circuit' or use the thermal fuse circuit ^ A person who recovers to form a permanent circuit open (OFF) state. , molten alloy Ο 鳌 [Prior Art] The use of electricity is indispensable in the modern human society - the ring, the equipment around the life, especially i ^ η 产时通, 教古化, Beixin industry, home, exchange, teaching Month, entertainment, etc., there is no electricity. The relative ^ 乂 is that modern people cannot be careless. In general, Wang and Dian also implement the switch in the overall circuit circuit that supplies electricity. [Generally, the main switch is the state of the power-on pottery. The power-control master, when there are too many appliances used in the circuit loop; ^ 4 fuse or power-off ^ When you are eager, you are guaranteed to be in the off state. In the normal private circuit, there are separate circuit loops, and the circuit returns to the switch of the two-two system. The switch is mainly used to execute the two current strokes of the respective current loops. Safety, the function of automatic power-off when the whole circuit is overheated when overloading 'avoids the current or tripping, and the risk of the second-line two-way stay = the power failure of the electrical breaker can not react immediately except the aforementioned overall circuit loop and Cut circuit loop, use fuse, break 201012020 electrical and switch current overload overheating automatic trip, power off structure, some single electronic, electrical products, such as: high-priced electricity, sub-products, information processing equipment or electricity The higher the number of electric heating appliances, etc., are also provided with circuit protection structures for temperature-sensing breakers, so as to protect the single electronic and electrical products. When the current of the single electronic and electrical products is overloaded, the circuit is overheated, Inductive and power-off, avoiding burning the product itself, and avoiding the individual circuit loops and overall electricity caused by the problems of single electronics and electrical products. Current circuit overload, over-temperature condition, causing the circuit loop, a problem other electrical equipment overall circuit loop not work. ® The conventional temperature-sensing power-off protector used in a single electronic product, as shown in the first to second figures, is provided with a contact elastic piece 101 in the circuit. The contact elastic piece 101 is curved, and is deformed after being heated. Bounce and bend, one end of the contact elastic piece is fixedly disposed on the first terminal 102, the other end of the contact elastic piece 101 is a free end, the free end is provided with a first conductive point 103, and the second terminal 104 is fixedly set with a second conductive Point 1 〇 5 'the second conductive point 1 〇 5 corresponds to the first conductive point 1 〇 3; in practice, the contact spring remains bent in the direction of the second terminal 104, so that the first conductive point 103 and the first end of the contact elastic piece 101 The second conductive point 105 of the two terminals 104 maintains the circuit communication state of the contact ©, as shown in the first figure; when the current is overloaded, the contact elastic piece 1〇1 is thermally deformed and bent in the opposite direction to bounce, so that the contact elastic piece 101 is free end. The first conductive point 103 is separated from the second conductive point ι5, and is in a state of being cut off (〇FF). As shown in the second figure, the circuit of the electronic product itself can be protected from burning. However, the disadvantages of the conventional temperature-sensing power-off protector are as follows: (a) When the contact spring piece 1〇 is made, it cannot be ensured that the thickness, the curvature and the structural characteristics of each piece of the contact elastic piece 1〇1 are completely the same, so that it is difficult to effectively control the contact. The reaction temperature value of the elastic piece 101 deformed after being heated and reversely bounced, and the temperature value of the induced induction is large. 6 201012020 (b) The contact shrapnel (8) is not deformed after the heat is deformed and reversed. The sharpness of the bounce is not high enough to protect the electronic product from overload and overheating. (4) The contact shrapnel 1G1 cannot be immediately tripped or disconnected, or the trip is incomplete, so that the circuit is still in a current conducting state, and the circuit continues to overheat, posing a danger to the electronic product and the entire circuit. When the current overload circuit is overheated, if the contact spring 1〇1 is in a half-bounce state, when the contact spring is cooled, it will jump back to the energized state, and the power will continue to be repeatedly turned off, and the power is turned off into a spark, causing danger and overall current. The electronic and electrical equipment in the circuit is repeatedly energized and powered off. The current is unstable, and the #machine may not operate normally, shortening the service life or even completely damaging it. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to solve the problem that the conventional temperature-sensing power-off protector has only one tripping and power-off device that is in contact with the shrapnel, and cannot effectively set the sensing temperature parameter of the power-off. And, when the current overload is overheated, if the contact shrapnel cannot be instantaneously jumped, the jump is not complete, or the jump is turned off, the circuit is continuously turned on, and the circuit generates sparking, and the power is turned off, causing the current to be unstable, causing the electronic product to crash.
