Abstract

The invention discloses an electric heating thermos flask, which comprises a flask shell, a liner, a flask cover, an electric heating element and a base, wherein the lower end of the flask shell is fixed on the base; the lower end of the liner is provided with an open annular catching groove; the lowest end of the liner below the open annular catching groove is provided with a flange which rolls inwards; the flange and the open annular catching groove can play a role of fixing the heating element; and an elastic gasket is arranged between the electric heating element and the liner to prevent water from immersing the electric heating element. The electric heating thermos flask has the following advantages: 1) the electric heating element is buckled at the bottom of the flask liner for providing convenience for disassembling and cleaning to avoid the phenomenon of rust for the electric heating element after long-term use; 2) hot water cannot be splashed so as no to hurt people when the electric heating thermos flask is tilted accidentally; 3) the flask cover is provided with two symmetrical water outlets; and when the flask cover is rotated to either water outlet symmetrical with a water outlet nozzle, water flows out, so the electric heating thermos flask is quite convenient to use; and 4) a push-pull water locking valve switch is adopted and is not easy to damage after long-term use.

Description

technical field [0001] The invention relates to an electric heating thermos bottle. Background technique [0002] At present, in people's daily life, the electric heating thermos bottle is widely used because it has the advantage of being easy to use. The structural characteristics of the existing electric thermos bottle are: it includes two inner and outer inner bottles, a space is arranged between the inner and outer inner and outer inner two inner bottles, the upper part of the inner and outer outer inner bottles is provided with a bottle cap, and the bottom of the inner and outer inner bottles is provided with an electric heater. . The inner and outer bottle liners are usually made of metal, which is convenient for heating; the space between the inner and outer bottle liners can help prevent the direct conduction of heat from the bottle liner; the function of the electric heater at the bottom is to supplement the heating after the initial heating or the water temperatur...
