Temperature controller

Abstract

The invention discloses a temperature controller, comprising an upper seat shell which is provided with an elastic switch control mechanism; the middle part and the two sides of the back part of the upper seat shell are respectively provided with a middle part sleeve and a left and a right sleeve; a middle part spring sleeve and a left and a right spring sleeve are respectively sheathed in each sleeve and the bottom part extends out of the bottom surface of the upper seat shell; the upper parts of the side surface of the left and right spring sleeves respectively extend outward bumping; each spring sleeve is internally provided with the spring; the switch control mechanism comprises buttons and a left and a right elastic lever which are connected with the two sides of the switch control mechanism; the left and right elastic levers extend among a central electrode shrapnel, a conducting ring shrapnel and a bumping; the end parts respectively extend upward out of the top lever; the top surface of the upper seat shell is fixed with an upper seat base plate; the springs in the left and right spring sleeves are connected with the bottom surface of the upper seat base plate. The invention has reasonable structure, convenient use, and is safe and reliable, thus capable of reducing the difficulty of manufacturing techniques, improving the service life of the electric kettle and being widely installed on the electric kettle.

Description

technical field [0001] The invention relates to a temperature controller, in particular to a temperature controller applied to an electric kettle. Background technique [0002] At present, common electric kettles on the market are equipped with thermostats on their bases, and the thermostats usually have a steam switch and an anti-dry function. Among them, the working principle of the steam switch is: after the water is boiled, the steam will heat and heat up the steam sheet until the deformation jumps suddenly, and the moving contact of the circuit is separated from the static contact through the linkage action of the mechanism, that is, the circuit is cut off , stop heating. Among them, the working principle of the anti-dry function is: when the electric kettle is dry-boiled, the dry-burned sheet close to the bottom plate of the electric kettle will be deformed and suddenly jumped by a certain amount of heat, and the circuit will be cut off by the action of the linkage me...

AI Technical Summary

Problems solved by technology

The dry burning piece of the electric kettle with this structure will only deform and jump when the heat conduction plate on the bottom of the electric kettle reaches a certain high temperature, and the surface flatness of the heat conduction plate has a great influence on the temperature transfer, resulting in the heat conduction plate. The production process requirements are very high, which increases the difficulty of product production; in addition, if people accidentally put the empty pot without water directly into the base during use and turn on the button for heating, although the dry pot on the thermostat The burning sheet can provide power-off protection for this situation, but the high temperature generated by dry burning will still affect the parts of the electric kettle, especially the electric heating tube, which reduces the service life of the product; in view of the above shortcomings, it is necessary to make improvements
