Multifunctional electric heating cup

Abstract

The invention discloses a multifunctional electric heating cup which comprises a cup body provided with a handle; a cup main body for holding liquid and a heating assembly for heating liquid are arranged in the cup body; the heating assembly comprises at least two electric heating tubes and a control circuit for controlling the working state of the electric heating tubes; the control circuit is provided with a voltage change-over switch; the electric heating tubes include an electric heating tube I and an electric heating tube II which are connected in the control circuit in parallel; and in the low-voltage state, both the electric heating tube I and the electric heating tube II are enabled to be in the working state through the voltage change-over switch, and in the high-voltage state, either the electric heating tube I or the electric heating tube II is enabled to be in the working state through the voltage change-over switch. A double-voltage design is adopted in the invention, the electric heating cup is switched over between the functions of heating liquid and producing steam through a two-way power switch, and the working state of the electric heating tubes I and II is changed through the voltage change-over switch, so that the electric heating cup can work under different working voltages but keep consistent power; and the multifunctional electric heating cup has the advantages of convenience, quickness, safety, reliability and high practicability.

Description

[0001] The patent application for this invention is a divisional application [0002] The filing date of the original application is: August 18, 2010 [0003] The application number is: 201010258903.1 [0004] The name of the invention is: a multifunctional electric heating cup. technical field [0005] The invention relates to domestic electric appliances, in particular to a multifunctional electric heating cup. Background technique [0006] There are many electric heating cups on the market. In addition to heating general liquids, they can also generate steam. However, the heating circuit is often unreliable. When heating liquids, there will be dry burning. When generating steam, the efficiency is not high and the safety factor is not continuous.

Problems solved by technology

[0006] There are many electric heating cups on the market. In addition to heating general liquids, they can also generate steam. However, the heating circuit is often unreliable. When heating liquids, there will be dry burning. When generating steam, the efficiency is not high and the safety factor is not continuous. Low, it may cause harm not only to the appliance itself but also to the user

When a cup cover with other functions is installed on the cup body of the electric heating cup, especially when steam is generated, if the seal between the cup cover and the cup body is not good, the steam will leak and easily burn the user

In addition, when carrying an electric heating cup during travel, the power of the electric heating cup may be different due to the different voltage of the power supply used, and the function of the electric heating cup cannot be well realized, especially when the electric heating cup suitable for low voltage only has high voltage, it will not be able to May burn if used or forced
