Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to an adjustable temperature controller. Background Art

[0002] A thermostat refers to a series of automatic control components that produce certain special effects and conduction or disconnection actions by physically deforming the inside of the switch according to the temperature changes in the working environment. The bimetallic thermostat is one of many types of thermostats. The bimetallic strip used is made by pressing two metals with very different thermal expansion coefficients together. At different temperatures, the difference in deformation of the two metals causes the bimetal to bend. This deformation is used to drive the quick mechanism to drive the switch contacts to close and open.

[0003] When the bimetallic strip and other components inside the bimetallic thermostat are damaged, they need to be removed and replaced. However, the shell and shell cover of the current thermostat are directly pressed. When the thermostat fails, it can only be discarded and replaced with a new one, which will increase the cost of use. Utility Model Content

[0019] The bimetallic strip 5 is connected to the aluminum cover 2. The temperature of the aluminum cover 2 can be transmitted to the bimetallic strip 5. The back jump of the bimetallic strip 5 can drive the ceramic column 9 to rise and fall. The rise and fall of the ceramic column 9 separates the lower contact of the spring sheet connector 7 from the upper contact on the fixed contact piece 6.

[0020] Ear blocks 17 are installed on both sides of the aluminum cover 2 , and strip-shaped installation holes 18 are opened on the ear blocks 17 .

[0021] Specifically, an insulating ceramic ring 8 is provided between the first wiring terminal 3 , the second wiring terminal 4 and the bimetallic strip 5 .

[0022] Specifically, the adjusting member is a screw rod 10 , the screw rod 10 is threadedly connected to the connector housing 1 , and the end of the screw rod 10 abuts against the spring sheet connector 7 .

[0023] In this embodiment, the screw rod 10 contacts the spring sheet connector 7 , and the pressure applied by the screw rod 10 to the spring sheet connector 7 can be adjusted so as to control the deformation amount of the spring sheet connector 7 .

[0024] The screw rod 10 is made of insulating material.
