Quickly-cooling vacuum cup

Abstract

The invention provides a quickly-cooling vacuum cup and belongs to the technical field of daily necessities. The quickly-cooling vacuum cup solves the problem that people cannot conveniently drink cold water or warm water when using an existing vacuum cup. The quickly-cooling vacuum cup comprises a cup body, an inner container, an inner plug and a cup cover. A vacuum cavity is arranged between the outer surface of the inner container and the inner surface of the cup body. A cup mouth portion communicated with a cavity of the inner container is arranged at the center of the upper end of the cup body. One side of the cup mouth portion is further provided with a cooling groove. The upper end of the cup body is covered with the cup cover, and the cup cover and the upper end of the cup body can rotate relatively in the circumferential direction of the cup body. The cup cover seals the cooling groove and is provided with a drinking water opening which is communicated with the cooling groove. The inner plug is inserted into the cup mouth portion and is located between the cup cover and the cup body. The side wall of the cup mouth portion is provided with a water outlet communicated with the cooling groove and the cavity of the inner container. The outer side face of the inner plug is provided with a water outlet gap. The water outlet gap is communicated with the water outlet and the inner cavity of the inner container by rotating the inner plug. The quickly-cooling vacuum cup has the heat preservation function and also has the rapidly cooling function due to the arrangement of the cooling groove.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and relates to a quick-cooling thermos cup. Background technique [0002] The thermos cup is generally a water container made of ceramics or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. Now the thermos cup tends to be multi-functional, and the quick cooling function is also a major development trend. [0003] At present, a quick-cooling cup, such as a portable cup with a cooling space disclosed in the patent (CN200420112209.9), mainly includes a cup body and a cup cover. The upper port of the cup body forms a ring-shaped cooling space, and the inner wall of the cooling space A first water outlet is provided, and the bottom surface of the circular cup cover that covers the cup body has a circular abutment w...

Problems solved by technology

[0004] However, although the above-mentioned quick-cooling cup has the function of rapid cooling, the cup body is an ordinary cup body and does not have the function of heat preservation. Therefore, it is impossible to achieve the organic combination of rapid cooling under the premise of heat preservation, which causes inconvenience for consumers.
