Problems solved by technology

Submerge the heating part of the electric heating tube in the liquid, turn on the current, and the liquid can be heated; once the use is improper or the operation is wrong, if the electric heater is not immersed in the heating liquid before the power is turned on, or for a long time The heating, the water evaporates, and the electric heater is "dry burned" in the air. At this time, the electric heater will be burned, and even cause a fire. Therefore, its safety factor is low

Abstract

This invention belongs to the compact home electric appliance, especially the electric heater with three safety valves. It comprises helicoids shape metal pipe, electric-heat wire, electrical insulating material, power plug. All of them electrically connect by the sequence. The structure comprises housing, temperature-sensing magnet steel temperature limiter, dual-metal plate temperature controlling apparatus, buoyancy sensing inching switch, and heat diffusion shell. On the circuit between two sides of electric-heat wire and power plug, wherein series buoyancy sensing inching switch, and connects temperature-sensing magnet steel temperature limiter, dual-metal plate temperature controlling apparatus and indicator. This invention has multiple level of security protection on circuit.

Description

technical field [0001] The invention belongs to small household electrical appliances, in particular to a triple safety electric heater with safety protection. Background technique [0002] At present, the small electric heaters used in daily life, commonly known as "heat quickly", use it to heat milk, boil water, make coffee, soybean milk, fast and convenient, and cheap, small and exquisite, high thermal efficiency, rapid heating, can be Widely used by people; especially suitable for home, school and office living places. It consists of installing heating wires in a spiral metal tube, filling insulating materials around the heating wires in the tube, so that the resistance wires are packaged and fixed in the center of the tube without touching the tube wall, and the two ends of the heating wires are connected to the power supply. Submerge the heating part of the electric heating tube in the liquid, turn on the current, and the liquid can be heated; once the use is improper...
