AI Technical Summary

Technical Problem

The existing temperature-controlled protector needs to be connected in series with the thermostat and the protector, resulting in complex circuits and inconvenient use.

Method used

Design a temperature control integrated protector, which controls the push rod and the moving contact assembly through the membrane box drive assembly to realize the integrated design of temperature sensing and circuit disconnection or connection, including the membrane box, the membrane handle, the temperature adjustment shaft, the capillary and the temperature sensing cylinder. The liquid expansion in the temperature sensing cylinder pushes the diaphragm box to press the push rod down, and the push rod pushes the movable contact assembly to disconnect or contact terminals.

Benefits of technology

It realizes automatic disconnection or switching on the circuit at different temperatures, simplifies the circuit structure and improves the convenience of use.

Abstract

The utility model discloses a temperature control integrated protector, which comprises a main body, a temperature adjusting plate, a push rod, a diaphragm capsule driving assembly, a terminal, a first movable contact assembly and a second movable contact assembly, a switch box is arranged at the bottom of the main body, and a partition plate is arranged between the switch box and the main body; the temperature adjusting plate is arranged in the main body through a pin; the push rods comprise first push rods and second push rods; the two diaphragm capsule driving assemblies respectively press down the first push rod and the second push rod; the terminal is arranged in the switch box, and the first movable contact assembly is connected with the first terminal; in the working process, when the temperature exceeds the preset first temperature, the first diaphragm capsule driving assembly downwards presses the first push rod; when the temperature exceeds the preset first temperature, the first movable contact piece assembly is pushed downwards by the first push rod which moves downwards, so that the movable contact piece assembly is disconnected from the second terminal, and when the temperature exceeds the preset second temperature, the second diaphragm capsule driving assembly presses the second push rod downwards; and the second movable contact assembly is pushed downwards by the second push rod which moves downwards, so that the movable contact assembly is in contact with the third terminal for further protection.
