The invention discloses a mechanical high-sensitivity temperature induction switch. The switch comprises an insulated upper shell, an insulated lower shell, an auxiliary thermal induction sheet, a bimetallic sheet and an insulated pushing rod. The insulated upper shell and the insulated lower shell are manufactured through injection molding or integrated molding respectively, and there is no screw hole or a slit in a surface so that an electric conductor can be effectively prevented from entering into an accommodating chamber and sensitivity of the temperature induction switch is increased. The surface of the insulated upper shell is provide with the auxiliary thermal induction sheet which is directly contacted with an electrical heating element so that sensitivity of temperature change induction of the temperature induction switch is improved, and simultaneously, the auxiliary thermal induction sheet is isolated from an electric component. The bimetallic sheet is contacted with the auxiliary thermal induction sheet and simultaneously is directly contacted with the electrical heating element. The insulated pushing rod is arranged so that insulating performance of the temperature induction switch is further increased. The structure of the induction switch is simple and the switch is easy to assemble. The switch is suitable for batch industrial production. An auxiliary insulation sheet is tightly contacted with the surface of the insulated upper shell and the surface is smooth. A contact area with the electrical heating element is large and sensitivity is high. A temperature reaction speed is fast and safety performance is high.
Description
technical field [0001] The invention belongs to the technical field of temperature control, and relates to a temperature sensing switch and a sensing method, in particular to a mechanical high-sensitivity temperature sensing switch and a sensing method. Background technique [0002] Temperature sensor switch, also known as temperature control switch, also known as thermostat or temperature controller, is an intelligent or non-intelligent switch that controls temperature. It can be used in temperature control occasions such as various household appliances, electromechanical equipment, etc. The set value is adjusted to achieve a suitable temperature. For household appliances, the temperature sensor switch can not only adjust the temperature, but also save energy, which is in line with the concept of green home appliances advocated by modern society. [0003] The temperature sensor switch specifically refers to the physical deformation in the switch according to the temperature...
