Electric heating bottle with thermal insulation layer

Abstract

The invention discloses an electric heating bottle with a thermal insulation function. The electric heating bottle comprises a bottle body, a heating base and a water storage bladder, wherein a bottle handle and a bottle cover are arranged on the bottle body; the water storage bladder is arranged inside the bottle body; a power line connected with a power supply is arranged on the heating base; the electric heating bottle also comprises a foamed thermal insulation layer; and the foamed thermal insulation layer is arranged between the bottle body and the water storage bladder. Because an interlayer of the electric heating bottle body, which is formed between the bottle body and the water storage bladder is filled with an expandable polystyrene foam material which forms a great quantity of independent hermetic bubbles, the heat conduction property of air is small and the air is sealed in the bubbles and cannot form convection, therefore, the electric heating bottle with the thermal insulation function, provided by the invention, has excellent heat insulation property and higher electric heating speed is higher, ensures that boiled water is not easy to cool, and is beneficial to saving electricity and energy.

Description

Technical field: [0001] The invention relates to an electric heating bottle, in particular to an electric heating bottle with heat preservation function. Background technique: [0002] The working principle of the heater is to install a primary coil with more turns and a secondary coil with fewer turns on the same iron core. The voltage ratio of the input to the output is equal to the ratio of the turns of the coil, while the energy remains constant. Therefore, the secondary coil generates a large current at a low voltage. For an induction heater, the bearing is a shorted single-turn secondary coil that passes a high current at a low AC voltage, thus generating a lot of heat. The heater itself and the yoke are kept at normal temperature, and since this heating method can induce an electric current, the bearing will be magnetized. It is important to ensure that the bearings are demagnetized in the future so that they do not attract metal chips during operation. FAG inducti...
