Description
Technical field
The present invention relates to a kind of temperature controller, specifically a kind of thermal sensitivity Kick type temperature controller.
Background technology
At present, traditional bimetal leaf Kick type temperature controller is encapsulated by a capping for sealing, and main action component is
One discoidal bimetallic thermal sensitive piece, bimetallic thermal sensitive piece understands reverse kick after being heated, by the ceramic bar inside temperature controller
Movable contact spring is promoted, so as to the break-make for realizing moving contact with determine contact.
Because temperature controller is that, by temperature sensing part control, temperature sensing part absorbs heat and needs certain heat transfer time, thus
The shortcomings of there is slow temperature-sensitive responsiveness, poor sensitivity in this traditional bimetal leaf Kick type temperature controller, it is impossible in overtemperature
Circuit is cut off in the very first time in time, but needs to wait the heat absorption time more long, allowed the heat of temperature-sensitive action component to reach and set
After fixed critical-temperature, temperature controller could kick action.Thus the environment temperature around equipment heating part is caused to be higher than temperature control
The device temperature to be controlled, particularly some powerful firing equipments, the temperature-sensitive speed of temperature controller substantially lag behind controlled member,
So as to accelerate the aging of equipment component, the service life of equipment is directly reduced, even fire incident can be caused when serious
Generation, reduce the functional reliability of temperature controller.
The content of the invention
It is an object of the invention to provide a kind of thermal sensitivity Kick type temperature controller, to solve asking for existing temperature controller poor sensitivity
Topic.
What the present invention was realized in：A kind of thermal sensitivity Kick type temperature controller, including capping, bimetal leaf, leading truck, shell
Body, actuating strut, determine contact assembly, moving contact component, rivet and two binding posts；It is described to determine contact assembly, moving contact component
Connect and be pressed on the housing with the corresponding binding post by rivet respectively；The edge of the bimetal leaf is abutted
At the top of the leading truck, wherein,
The housing is hollow cavity body structure, and the leading truck is arranged on the top of the housing, in the leading truck
The through hole being provided centrally with for accommodating actuating strut；Abutting part and connecting portion, the connection are provided with the leading truck
The external diameter in portion is less than the external diameter of the abutting part, and the connecting portion of the leading truck is stretched into the housing；
The capping includes top surface and skirt section, and the skirt section of the capping is closely pressed together on the outer wall of the housing；Institute
State and through hole is provided with the top surface of capping.
Preferably, the number of openings is one, is arranged on the center of the top surface, and the radius of the through hole is less than described
The radius of top surface.
Preferably, the number of openings is at least two, uniformly on the top surface, being shaped as the through hole be circular,
Rectangle or polygon.
Preferably, the reinforcement structure for preventing capping from deforming is provided with the inner surface of the capping top surface.
Preferably, the reinforcement structure is provided in covering the ribs in top surface inner surface and inner skirt surface.
Preferably, the thickness of the cover closing material is 0.1-0.3mm.
Preferably, the action bar material is ceramics.
The present invention has added through hole on the basis of original capping, and reduction outside heat is transferred to obstruct during bimetal leaf
Effect, the temperature of thermal element more rapidly can be transferred on bimetal leaf.The thermal response time of the invention is than original tradition temperature
Control device shortens 80%, whole temperature controller structure design has been reached quick temperature-sensitive, highly sensitive effect.
