Double-layer vacuum-type electric heating water boiling thermos bottle

Abstract

The invention discloses a double-layer vacuum-type electric heating water boiling thermos bottle in order to overcome the defects of inferior thermal insulation effect, considerable energy waste and quite high housing temperature caused by the fact that a through opening cylinder is arranged between the base plates of an inner tank and a housing to form a channel for the base plate of the inner tank to transfer and dissipate heat outwards in the prior art. The technical scheme is as follows: the thermos bottle comprises a housing, an inner tank, a bottle top sealing cover, a bottle leg base, an electric heater, an electric pump and a control circuit, wherein a vacuum thermal insulation layer is formed between the housing and the inner tank and the electric heater is arranged at the bottom inside an inner tank cavity; the thermos bottle is characterized in that a power supply lead of the electric heater is led out through a conduit of the inner tank cavity from the upper opening of the inner tank, the electric pump is divided into two parts including a motor and a pump body, the motor is installed inside the bottle leg base, a magnetic rotating disc is installed on a motor shaft, the pump body is installed at the bottom inside the inner tank cavity, another magnetic rotating disc is arranged on the bottom surface of an impeller of the pump body, the magnetic rotating disc of the motor is in attraction fit with the magnetic rotating disc of the impeller in such a manner that the vacuum layer of the inner tank and the housing is arranged between the two magnetic rotating discs, and a water outlet channel of a pump body cavity is connected with a water outlet pipe which is arranged inside the inner tank cavity and is led out through the upper opening of the inner tank.

Description

technical field [0001] The invention belongs to an electric heating boiling liquid container, in particular to a double-layer vacuum type electric heating boiling water thermos bottle. Background technique [0002] Existing double-layer vacuum type electric heating thermos bottle at present is like a kind of electric heating thermos pot of Chinese Patent No. 02225782.9. Circuits, etc., wherein a vacuum insulation layer is formed between the side wall of the shell and the bottom plate of the shell and the inner tank, the electric heater is arranged on the bottom of the inner tank cavity, the bottle top cover is installed on the top of the outer shell and the inner tank, and the bottle foot is installed At the bottom of the shell, the control circuit is installed in the base of the bottle or the top cover of the bottle, and the electric heater is set at the bottom of the inner tank cavity, and the electrode lead of the electric heater is connected from a port between the botto...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the existence of the existing double-layer vacuum type electric heating thermos bottle, there is a through-hole cylinder between the bottom plate of the inner tank and the bottom plate of the shell, which constitutes a path for direct heat transfer and heat dissipation from the bottom plate of the inner tank to the shell, resulting in poor heat preservation effect and low energy consumption. The disadvantages of large waste and inconvenient use due to high shell temperature, the purpose of the present invention is to provide an improved double-layer vacuum electric heating thermos bottle, which can overcome the defects of the prior art
