Description

Technical Field

[0001] The present invention relates to the technical field of electric kettles, in particular to an electric kettle capable of rapidly cooling down. Background Art

[0002] Chinese patent document CN208925887U, published on June 4, 2019, discloses a milk mixer comprising a body and a base. The body is provided with an electric heating device, which is detachably mounted on the base. The bottom of the body is connected to the base via a connector to electrically connect the electric heating device to the circuit of the base. The upper portion of the base is provided with a base trough body that fits the bottom of the body, the base comprising a bottom wall and a retaining wall surrounding the bottom wall, and the base is provided with a drainage channel connecting the base trough body and the outside of the base. The body of the milk mixer is not made entirely of glass; a metal bottom plate is provided at the bottom of the body, which makes the use of the body less hygienic and environmentally friendly. In addition, some milk mixers on the market use an all-glass structure. After the body is filled with hot water, if the body is placed on a table with a lower temperature, it is easy to burn the table and the body is easy to burst. The bottom of the glass kettle body is a flat or non-flat structure; when the bottom of the glass kettle body is a flat structure, the glass kettle body is placed on the table with almost no gap between the bottom of the glass kettle body and the table. At this time, due to the effect of atmospheric pressure, the glass kettle body is difficult to pick up from the table; when the bottom of the glass kettle body is a non-flat structure, the glass kettle body is placed on the table with a gap between the bottom of the glass kettle body and the table. If the glass kettle body is filled with hot water, the air in the gap will expand due to thermal expansion and contraction. When the hot water is left for a period of time and becomes cold, the air in the gap will shrink due to thermal expansion and contraction. At this time, the air pressure in the gap is less than the atmospheric pressure, and the glass kettle body is difficult to pick up from the table. Moreover, when the bottom of the glass kettle body is a non-flat structure, if there is residue on the bottom of the glass kettle body, the glass kettle body will be placed on the table, and the residue will fill the gap between the bottom of the glass kettle body and the table. At this time, it is equivalent to having almost no gap between the bottom of the glass kettle body and the table. Due to the effect of atmospheric pressure, the glass kettle body is difficult to pick up from the table.

[0003] Therefore, further improvements are necessary. Summary of the Invention
