Abstract

The invention discloses a heater, including a metal matrix layer, an insulating medium layer sintered on the metal matrix layer, a first electrode and a second electrode sintered on the insulating medium layer, and a heating resistor sintered on the insulating medium layer. The heating resistor comprises a first connecting end and a second connecting end. The first connecting end is connected withthe first electrode. The second connecting end is connected with the second electrode. The heater also comprises a thermal fuse sintered on the insulating medium layer. One end of the thermal fuse stretches across the heating resistor on the first connecting end, and the other end of the thermal fuse stretches across the heating resistor on the second connecting end. The heater can provide safetyprotection when abnormal conditions occur, to prevent to cause severe risk.

Description

technical field [0001] The invention relates to the technical field of heating electrical equipment, in particular to a heating device. Background technique [0002] Generally speaking, when the heater is working abnormally, the overheating position is on the heating resistor, but the heating resistor is charged when it is working. It is necessary to install a jump-type thermostat after the insulating layer is placed on the surface of the heating resistor, and use a bimetallic sheet for temperature protection. The heater is overheating. [0003] Taking the thick film heater as an example, under normal circumstances, the sudden jump thermostat of the thick film heater can protect the thick film heater by cutting off the power supply when the thick film heater is dry or partially dry. purpose of film heaters. However, there are also thermostat protection failures, which cause the thick film heater to fail to cut off the power in time under abnormal heating conditions, result...
