Description

Technical Field

[0001] The utility model relates to the field of temperature controllers, in particular to a temperature controller with heat insulation transmission. Background Art

[0002] The current thermostat mainly includes a coupling upper seat and a metal heat-conducting frame. The edge of the metal heat-conducting frame is bent into several folded feet by stamping, and through holes are provided on the folded feet. The coupling upper seat is provided with threaded holes corresponding to the through holes, and screws are screwed through the through holes or self-drilled into the threaded holes, so that the metal heat-conducting frame and the coupling upper seat are tightly connected. However, in actual use, it is found that when the metal heat-conducting frame reaches a high temperature due to dry burning of the heating plate, the heat is directly transferred to the coupling upper seat made of plastic material through the folded feet, or indirectly transferred to the coupling upper seat through screws, which can easily cause heat melting at the contact point between the coupling upper seat and the folded feet, causing the metal heat-conducting frame and the anti-dry burning device to collapse as a whole, and the anti-dry burning structure to fail, affecting the safety of the thermostat. Therefore, it is necessary to further improve the current thermostat. Utility Model Content
