Problems solved by technology

[0003] This structural setting leads to the fixed connection of each working part with the mounting plate, and the pressure of the inner pot drives the selection, and then produces up and down movements to realize no pot and detection. The continuous bending and extension of the lead wires of the working parts will easily cause the problem of poor contact at each node.
The unreasonable setting of the overall structure of the existing sensor leads to low integration, high assembly accuracy requirements and low assembly efficiency between components

Abstract

The invention relates to the technical field of temperature control sensors, in particular to a PTC integrated sensor. The PTC integrated sensor comprises a base. A sensing component is arranged in the base. The upper end of the base is sleeved with an upper cover which independently acts relative to the base. A compression spring is arranged between the base and the upper cover. The upper cover is in abutting linkage with the sensing component in the base in the downward-pressing process. The sensing component comprises an overheating power-off device provided with a heat keeping device. According to the PTC integrated sensor, when the temperature rise of an inner pot exceeds a thermistor set value, a main control panel circuit is switched off to achieve power-off protection; a heating circuit can be switched off when a contact piece deforms, at the moment, the PTC heating source heats a temperature sensing piece, and the power-off state is kept to prevent the problem that the contact piece is cooled and connected with the heating circuit again; a fusing core is directly molten through high temperature, and the heating circuit is switched off with force to achieve final protection; the temperature sensing piece and an insulation support are used as stress reaction components, the off-line problem of lead welding points is reduced, and the sensor is high in overall integration, convenient to maintain and stable to trigger and is perfectly protected.

Description

technical field [0001] The invention relates to the technical field of temperature control sensors, in particular to a PTC integrated sensor. Background technique [0002] Chinese patent CN201422761Y discloses a micro switch type anti-dry device, including a mounting cup, a micro switch and a switch support plate, the micro switch is set in the mounting cup, the mounting cup is installed on the switch support plate, and installed There is a return spring between the cup and the switch support plate, and the switch support plate is fixed on the installation base. When the cup is released, the heating circuit is disconnected. [0003] This structural setting leads to the fixed connection of each working part with the mounting plate, and the pressure of the inner pot drives the selection, and then produces up and down movements to realize no pot and detection. The continuous bending and extension of the lead wires of the working parts will easily cause the problem of poor cont...
