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

Embodiment Construction

[0018] The following examples are further explanations and descriptions of the present invention, and do not constitute any limitation to the present invention.

[0019] Refer to Figure 1 ~ Figure 3 , The shrapnel-type power-off reset temperature control switch capable of controlling two circuits of the present invention includes a metal shell 10, a plurality of connection terminals 20, a metal end cover 30, a ceramic guide heating element 40, a bimetal 50, a movable spring 60 and Static contact piece 70.

[0020] Such as Figure 1 ~ Figure 3 As shown, the metal shell 10 is a copper hollow cylindrical body, one end of which is open, and the end of the open end is provided with an outwardly protruding rim 11 for connecting the heating element 40 of the ceramic guide frame. At the bottom of the metal shell 10, two grooves 12 for installing connection terminals are provided, and the two grooves 12 are symmetrically distributed on the center line of the bottom of the metal shell 10.

Abstract

Disclosed is a spring-type power failure restoration temperature control switch capable of controlling two kinds of circuits. The temperature control switch comprises a metal shell, two 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 and a static contact piece provided with a static contact. When the temperature of loads reaches a set value, the bimetallic strip is heated to kick, the movable contact and the static contact are separated to open the circuits, 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. The temperature control switch can control two kinds of load circuits at the same time and has power failure protection and power failure restoration functions.

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 two load circuits at the same time, and having both power-off protection and power-off reset functions. 【Background technique】 [0002] At present, various electrical equipment 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 the 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 the equipment to malfunction, thereby affecting the normal use of the equipment. For this reason, general electrical or electronic equipment is equipped with temperature switches or ...
