Problems solved by technology

[0002] Thermal fuses are also called thermal fuses, which include metal shells, temperature-sensitive particles, front gaskets, rear gaskets, drum springs, breaking electrodes, breaking springs, ceramic beads, riveting wires and contact wires. The riveting wires are riveted on One end of the metal shell, and then temperature-sensitive particles, gaskets, drum springs, rear gaskets, breaking electrodes, breaking springs and ceramic beads are tightly installed on the metal shell in turn, and the contact wires are connected to the ceramic beads. The metal shell port at the connection is sealed with epoxy resin, because the fusing temperature of the thermal fuse used in the current rice cooker is determined by the melting temperature of the temperature-sensing particles; the optimal operating temperature of the thermal fuse in the rice cooker should be 168°C, while the operating temperature of the thermal fuses currently used in rice cookers is either high at 172°C or low at 166°C, which cannot meet the actual requirements of electric cookers for thermal fuses

Abstract

The invention relates to a thermal link for an electric cooker. The thermal link comprises a metal shell, temperature-sensitive particles, a front gasket, a back gasket, drum-shaped springs, a breaking electrode, breaking springs, porcelain beads, rivet lines and contact lines, wherein metal shell ports at the joints of the contact lines and the porcelain beads are sealed with epoxy resin. The thermal link is characterized in that the temperature-sensitive particles comprise the following components in percentage by weight: 40-60 percent of p-methoxybenzoic acid, 10-40 percent of hexanedioic acid and 5-30 percent of mannitol. The thermal link for the electric cooker has the advantage of optimal melting temperature.
