Temperature control electric connector for liquid heater

Abstract

This invention relates to temperature-control electric linker used in separated cordless liquid heating devices to provide a rotary temperature-control electric linker integrating the temperature control, metal thermal cut-off and an electric linker including an upper coupler and a lower coupler, in which, a temperature controller and a metal thermal cut-off are set on the side of the upper coupler and are sealed in a structure integrating the temperature controller, the metal thermal cut-off and the upper coupler shell into one.

Description

Technical field [0001] The invention relates to the technical field of electric heating devices, in particular to a temperature control electrical connector used in separate cordless liquid heating devices such as electric coffee pots, electric kettles, milk warmers, egg cookers, electric tea kettles and the like. Background technique [0002] Various electrical connectors used in liquid heating devices such as existing electric coffee pots, electric kettles, milk warmers, egg cookers, and electric tea kettles have the following shortcomings during use: [0003] 1. The temperature control of the heating device mostly uses exposed bimetallic strips to contact the heat source. Due to the influence of the use environment, the exposed bimetallic strips are susceptible to contamination, aging, and unstable temperature induction, resulting in poor temperature control performance. [0004] 2. As a key component of safety protection, most of the fuses are conductive plastic fuses, which ...

AI Technical Summary

Problems solved by technology

[0003] 1. The temperature control of the heating device mostly uses exposed bimetallic strips to contact the heat source. Due to the influence of the use environment, the exposed bimetallic strips are susceptible to contamination, aging, and unstable temperature sensing, resulting in poor temperature control performance.

[0004] 2. As a key device for safety protection, fuses mostly use conductive plastic fuses, which are affected by steam, media, and oxidation during use. Conductive plastics tend to age and become brittle, which affects the performance of thermal cut-off

[0005] 3. When most of the electrical connectors currently used are not docked and inserted, the power cord of the lower case remains energized, which is prone to electric shock

[0006] 4. The power contacts of the existing electrical connectors all adopt the shrapnel slow-moving contact design, which is very easy to generate arc sparks when the contacts are closed, resulting in unstable performance of the electrical connector, prone to short circuit and many other unsafe hazards
