Safety protector for electric heating container

Abstract

The invention relates to a safe protective device of electric heating container, which comprises a electric heating element formed by a electric heating ring and a heat conductive plate; a heat power device formed by a dual metallic plate and a top rod; and a electric switch formed by a movable contact point, a movable contact plate, a stable contact point and a stable contact plate. Wherein, thedual metallic plate are movably connected to one end of top rod; another end of top rod is supported to the movable contact plate; the central section of independent heat conductive device is insulated from the heat conductive plate which has at least one dual metallic plate; the independent heat conductive device has a thermal sensitive feeler heat connected to the heat conductive plate of electric heating container. The dual metallic actuator can feel the temperature via the feeler of heat conductive device; and the independent heat conductive device has tight heat contact with the heat conductive plate of heater to solve the problem of slow response speed. The invention has simple structure, fewer elements, and improved reliability and safety.

Description

Electric heating capacitor safety protection device technical field The invention relates to an automatic switch device for an electric heating container, in particular to a safety protection device for electric heating containers such as electric cups, electric kettles and coffee pots. Background technique In the existing bottom-heating electric heating containers such as electric heating cups, electric kettles, and coffee pots, a safety protection device is generally installed at the bottom. The energizing circuit of the container to prevent the burning of the appliance and endangering safety. At present, there are two kinds of representative controllers, and a kind of is "Thermal Sensitive Controller of Boiling Water Vessel" whose technical scheme is to be installed on each other by two bimetallic actuators with substantially the same temperature. At a position separated by a considerable distance, when the electric heating capacitor is locally overheated, it will be q...

AI Technical Summary

Problems solved by technology

The present invention aims at the technical problems existing in the above two electric heating capacitors, and proposes a new technical solution, which not only needs to solve the defect that the two pairs of metal sheets cannot compensate for each other to ensure safe use, but also solves the problem caused by the two pairs of metal sheets. The metal sheets are close to each other, because of the slow response speed in the weak heat zone of the container when local overheating occurs
