Technical Field
The invention relates to the technical field of household gas cookers, in particular to a temperature sensor for a gas cooker.
Background
Along with the improvement of living standard of people, the concept of healthy diet is gradually deepened into people, but the temperature is not easy to control in the cooking process of using a common gas stove, food is easy to burn and smoke due to overheating, and benzopyrene and heterocyclic amine which cause carcinogenesis of people are generated; therefore, the rapid, accurate and intelligent control of the temperature in the pan becomes a necessary trend and demand.
Most of the existing gas stove temperature sensors mainly have a dry-heating prevention function, the scheme of increasing the number of heat insulation layers is adopted to reduce the influence of flame radiant heat and hot air on the sensors, but temperature measurement points are generally in an open or semi-closed mode, are still greatly influenced by heat convection, cause slow response speed and large temperature detection errors, are not suitable for quickly and accurately responding to the temperature in a pot in a cooking process, and can only be simply suitable for the dry-heating prevention function in a cooking or large error range. Chinese patent application No. 2019101784432 discloses a gas-cooker temperature sensor, fire-proof thermal-insulated ability is strong, and the temperature measurement precision is high, and sensing cap swing range is great, but sensing cap has the defect of contact with heat conduction overcoat in the swing process to probably influence the accuracy of temperature measurement.

The utility model provides a gas-cooker temperature sensor, includes sensing cap subassembly, heat conduction overcoat subassembly and supporting component, and the sensing cap subassembly includes sensing cap, thermocouple and sensing cap heat insulating sleeve, and the sensing cap subassembly passes through sensing cap compression spring to be installed on supporting component's sleeve pipe, but sensing cap axial is flexible and radial swing, the helical structure that the sleeve pipe upper end of sensing cap heat insulating sleeve and supporting component corresponds with sensing cap compression spring, sensing cap compression spring's upper end and lower extreme are in the same place with sensing cap heat insulating sleeve and sleeve pipe upper end spiral respectively. Effectively prevent the displacement of sensing cap position, direct contact heat conduction overcoat subassembly.
Furthermore, the spring wire bends at the two tail ends of the compression spring of the sensing cap are respectively inserted into the small holes reserved in the heat insulation sleeve of the sensing cap and the sleeve, so that the sensing cap assembly is prevented from rotating.
The utility model discloses changing the installation of sensing cap compression spring into the cylinder cooperation by original terminal surface plane cooperation, improving the concentricity, the sensing cap is difficult eccentric, improves the reliable letter of temperature measurement, reduces the temperature measurement mistake, can reduce the plane degree requirement of ignoring sensing cap compression spring both ends even simultaneously. The utility model discloses compact structure, simple to operate, sensing cap swing range is great, with the kitchen utensil bottom in close contact with, can the various different kitchen utensils of self-adaptation and the put position of kitchen utensil, the reaction is sensitive, and the fire prevention is thermal-insulated can the reinforce, and the temperature measurement precision is high, and temperature transmission is accurate, and the reliability is high.
