This utility model relates to an automatic power-off thermal radiation liquid heater, which includes a kettle body assembly comprising a glass kettle body, a bottom shell, and a heating plate assembly. The heating plate assembly includes a heat insulation plate and a heating wire element, forming a thermal radiation cavity between the heat insulation plate and the glass kettle body; the outer peripheral wall of the conductive end of the heating wire element is insulated. The kettle body assembly also includes a liquid sensing element and a spring switch assembly. The spring switch assembly is electrically connected to the heating wire element. The sensing end of the liquid sensing element is located in the thermal radiation cavity. The liquid sensing element detects liquid parameters within the thermal radiation cavity, and the spring switch assembly disconnects the power supply to the heating wire element based on the electrical signal from the liquid sensing element. The liquid sensing element can promptly detect the presence of liquid in the thermal radiation cavity and output an electrical signal. Based on this electrical signal, the spring switch assembly can control the kettle body assembly to disconnect from the power supply, thereby achieving an automatic power-off effect.

The invention relates to a diaphragm, a lithium ion battery and electronic equipment. The diaphragm comprises a diaphragm body and a first coating arranged on at least one side of the diaphragm body, wherein the first coating is used for being bonded with a part, coated with a single-sided active substance layer, of a battery pole piece; the first coating comprises a high-temperature-resistant material; and the high-temperature-resistant material accounts for 17.5-46.3% of the total mass of the first coating. In the diaphragm, the first coating comprises the high-temperature-resistant material, so that the high-temperature-resistant performance of the diaphragm can be improved, the problem of short circuit caused by contact of a cathode and an anode due to internal shrinkage of the diaphragm can be avoided when thermal runaway of the battery occurs, and the reliability of the battery is ensured. Besides, the diaphragm is bonded with the part, coated with the single-sided active substance layer, of the battery pole piece through the first coating, so that the bonding force between the diaphragm and the part, coated with the single-sided active substance layer, of the battery pole piece is improved, and the reliability and the cyclicity of the battery are further improved.
