Problems solved by technology

However, the existing mechanical jump thermostats only have basic power-off protection functions, and can only control the temperature of a single load circuit, so their use is limited
On the other hand, many of these thermostats are automatically reset according to the temperature, so that some equipment has been automatically reset without eliminating the hidden danger of failure, so there is the possibility of failure again and potential safety hazards

Abstract

Disclosed is a spring-type power failure restoration temperature control switch capable of controlling multiple load circuits. The temperature control switch comprises a metal shell, multiple connection terminals and a metal end cap fixed to the metal shell, a ceramic guide frame heating element arranged between the metal end cap and the metal shell, a ceramic push rod movably and penetratingly arranged on the ceramic guide frame heating element, a bimetallic strip in contact with the ceramic push rod, a movable spring provided with a movable contact, a static contact piece provided with a static contact and a lower contact. When the temperature of loads reaches a set value, the bimetallic strip is heated to kick, and the movable contact and the static contact are separated to open the circuits. The other side of the movable contact is connected with the lower contact in a closed manner, and the ceramic guide frame heating element is energized to emit heat so as to enable the bimetallic strip and the temperature control switch circuit to be kept under the disconnected state. The bimetallic strip can restore only by deenergization so as to enable the temperature control switch circuit to be closed, and the ceramic guide frame heating element circuit is opened.

Description

【Technical field】 [0001] The invention relates to a temperature control device for electrical products, in particular to a shrapnel-type power-off reset temperature control switch capable of controlling multiple load circuits, which can simultaneously control multiple load circuits and has power-off protection and power-off reset functions. 【Background technique】 [0002] At present, various electrical appliances are widely used in people's lives, bringing convenience to people's lives. The safety of electrical equipment, especially electric heating equipment, is an important issue to be considered in product design and production. When the components or electronic circuits of electrical equipment fail, it will cause the equipment to heat up and the temperature will rise. When the temperature exceeds the normal value, it will cause equipment failure, thus affecting the normal use of the equipment. For this reason, general electrical appliances or electronic equipment are eq...
