Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and in particular to a novel temperature controller with ceramic film resistive heating. Background Technology

[0002] In modern electronic and electrical equipment, the thermostat is a key component. Its main function is to monitor and control the temperature of the equipment, ensuring that it operates within a safe temperature range. This is typically achieved through the automatic switching of circuits, thereby maintaining a constant temperature or preventing the equipment from overheating.

[0003] In traditional thermostat designs, the bimetallic strip is one of the core components. This design utilizes the deformation characteristics of the bimetallic strip at different temperatures. Through deformation, it moves related spring components, thereby separating or engaging the moving and stationary contacts, and ultimately controlling the on / off state of the circuit. This mechanism is widely used in various electrical and electronic devices due to its simplicity and reliability.

[0004] However, existing thermostats have some problems in compensating for temperature changes. Most compensating thermostats on the market use conventional heating wires for temperature compensation. While this method can meet temperature control needs to a certain extent, it poses significant safety hazards. When the compensating wire's power is too high, it will glow red, which not only wastes energy but may also cause fires and other safety problems. Furthermore, the compensating wire is prone to burning out if its power changes, leading to thermostat failure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the safety issues associated with using conventional heating wires for temperature compensation, and to propose a novel ceramic-coated resistive heating temperature controller.

[0012] The upper porcelain ring is attached below the bracket, and the gasket is attached above the bimetallic strip.

[0013] Further, the spring assembly is located between the upper lug and the lower porcelain ring, and the movable contact of the spring assembly and the fixed contact of the contact lug are oppositely arranged.

[0014] The spring assembly is provided with a porcelain column, and the bracket is provided with an adjusting knob for driving the porcelain column to move up and down on the movable contact.

[0015] Further, the connecting piece comprises a connecting portion and a sleeve portion, the connecting portion is fixed to the lower side of the bimetallic strip, and the sleeve portion is sleeved on the free end of the ceramic film resistor to force the ceramic film resistor and the tail end of the bimetallic strip to be attached.

[0016] Further, the sleeve portion is in a C-shaped structure, and a bent contact portion is further formed at the opening end of the sleeve portion.

[0017] Further, the outer side of the riveting piece is sleeved with a porcelain tube, and the bottom of the ceramic film resistor is further provided with a bottom lug and a bottom porcelain ring.
