Telescopic temperature sensor

Abstract

The present invention provides a telescopic temperature sensor which is used on the domestic gas range. The sensor is composed of a sensing head covering barrel, a sliding bush, a guiding bush and a guiding frame. The lower end of the guiding bush and the upper end of the guiding frame are respectively fixed on the base of the guiding frame, the guiding rod traverses the sensing head covering barrel, the sliding bush, the guide bushing and the guiding frame, the head of the guiding rod traverses the spring fixed in the sliding bush and the upper cover of the sliding bush and is embedded into the covering barrel of the detector head. The axial pin traverses the sliding chute on the wall of the guiding frame and the lower end head of the guiding rod and is fastened with a screw for connecting the guiding rod, the thermocouple is arranged in the covering barrel of the sensing head, the conducting wire is leaded to the outside of the guiding body and is arranged with a plug, the sensitiveswitch is arranged on the guiding body and the position is corresponding with the axial pin. The jam nut is screwed on the seat of the guiding frame. The telescopic temperature sensor has the characters of compact confirmation and high temperature measurement accuracy, and is especially suitable to be used as a temperature sensor on the built-in intelligent control gas combustion range.

Description

technical field [0001] The utility model relates to a temperature sensor, in particular to a telescopic temperature sensor used in civil gas stoves. Background technique [0002] The temperature sensor commonly used on civil gas cookers is basically a thermocouple fixed on the burner burner, and the temperature is measured by direct combustion of the combustion flame. Since the thermocouple temperature measuring device does not touch the bottom of the cooker, the internal temperature measurement of the cooker is not accurate. Therefore, the intelligent temperature-controlled gas stove with automatic temperature measurement as the control signal source cannot be used as a temperature measurement device. Contents of the invention [0003] The purpose of the utility model is to provide a telescopic temperature sensor which can accurately measure the internal temperature of the cooker. [0004] The utility model is realized in the following manner. The telescopic temperature...
