Abstract
The invention discloses a temperature controller. The temperature controller comprises a wireless base connector, a movable contact piece with a movable contact, a fixed contact piece with a fixed contact, a steam sheet, dry burning sheets and a switching device. The switching device comprises a connecting rod assembly and elastic pieces. The connecting rod assembly comprises a movement rod and a separation rod. The dry burning sheets are deformed to drive the separation rod to move in the axial direction of the separation rod and are matched with a wedge-shaped face between the separation rod and the movement rod to drive the movement rod to move in the axial direction of the movement rod. The movement rod is provided with a slope structure which abuts against the movable contact piece, the movement rod pushes the movable contact piece to move in the direction far away from the fixed contact in the moving process through the slope structure, and a mounting cavity capable of containing one part of the steam sheet is formed in the other end of the movement rod. The steam sheet is heated to be deformed so as to drive the movement rod to make axial movement and pushes the movable contact piece to move in the direction separating from the fixed contact through the slope structure. The two ends of each elastic piece are fixedly arranged on the movable contact piece and the wireless base connector respectively. The temperature controller has the advantages of being high in safety performance, small in size, saving in materials and low in cost.
