A thermostat for an electric kettle

Abstract

The invention relates to an electric kettle thermostat including a plastic upper seat and a seesaw. A bottom end of the plastic upper seat is provided with a plugging portion. A live wire elastic sheet and a neutral wire elastic sheet are disposed on the plugging portion. A top end of the plastic upper seat is connected with an insulation cover plate. Two sides of the insulation cover plate are provided with two through-holes respectively. Thermo-sensitive temperature sensing sheet action assemblies are equipped on through-holes corresponding to top ends of operating levers. Each thermo-sensitive temperature sensing sheet action assembly comprises a thermo-sensitive temperature sensing sheet, a cap and a tight-supporting clamp spring. The thermo-sensitive temperature sensing sheets are clamped in the through-holes by the caps and the tight-supporting clamp springs. An insulation positioning frame is also connected onto a positioning platform and is fixed on the positioning platform via a fastener, and a live wire positioning conductive sheet and a neutral wire positioning conductive sheet are pressed and fixed on the positioning platform. The electric kettle thermostat is simple and reasonable in structure, secure, compact and reliable in connection, convenient in structure installation, long in service life and safe to use.

Description

technical field [0001] The invention relates to the technical field of electric kettles, in particular to a thermostat for electric kettles. Background technique [0002] At present, the existing electric kettle thermostat has a heat-sensitive temperature plate structure, such as the invention patents of Chinese Patent No. 00103897.4 and 200810120109.3. The heat-sensitive temperature plate is fixed through the inner tongue and the inner tongue jack. The position is limited by each positioning point, the fixing method is not strong enough, the processing technology is high, and the processing is difficult, resulting in a high scrap rate. For example, if the inner tongue hole is too large or too small, it is easy to cause the inner tongue of the heat-sensitive thermal film to be inserted. The interference fit or excessive fit of the time makes the outer sudden jump wing unable to press fit with the push rod when it is deformed at high temperature. For example, the height of th...

[0002] At present, the existing electric kettle thermostats have heat-sensitive temperature sheet structures, such as the invention patents of Chinese Patent No. 00103897.4 and 200810120109.3. The heat-sensitive temperature sheets are fixed through the inner tongue and the inner tongue jack. The position is limited by each positioning point. The fixing method is not firm enough, the processing technology is high, and the processing is difficult, resulting in a high scrap rate. The interference fit or excessive fit during the time makes the outer sudden jump wing unable to press fit with the push rod when it is deformed at high temperature. For example, the height of the positioning point or the support limit point cannot meet the standard, which may easily cause the heat-sensitive temperature sheet to loosen. Moreover, due to the fixing method of the inner tongue and the inner tongue socket, the heat-sensitive temperature sheet must be provided with a through hole, and finally only a small area of ​​the edge is left on the part that fits the push rod, that is, the outer jumping wing in 200810120109.3 , if there is a small and cheap during assembly, that is, the top pressure cannot be achieved, that is, the overheating protection effect cannot be achieved

[0003] Furthermore, the metal conductive shrapnel of the existing electric kettle thermostat is fixed on the plastic upper seat by screws. This fixed connection structure is prone to slipping and loosening, resulting in poor contact of the conductive shrapnel even if the farmer households have poor contact, affecting the use effect, or even unable to Normal use
