Vacuum cup with quick cooling function

Abstract

The invention relates to a vacuum cup, particularly to a vacuum cup with a quick cooling function, and provides a vacuum cup with a quick cooling function, which has a simple structure, is convenient to use and can seal cooling liquid tightly. The vacuum cup with the quick cooling function comprises a cup body and a cup lid, wherein the cup body comprises an inner layer, a housing and a clearance layer between the inner layer and the housing; the liquid is sealed in the clearance layer and is lower than the lower end of the inner layer when the cup body stands. The liquid sealed in the clearance layer can be less, and the cup is not heavy and big and looks like a common double-layer vacuum cup. Drinking water over 90 DEG C in the cup can be cooled down in a few of minutes for drinking just by shaking the cup so as to meet the urgent need of an extremely thirsty person; drinking water can be cooled for drinking continuously cup by cup by shaking. The cup can also be shaken to adjust the temperature of the housing to satisfy a user to warm hands.

Description

technical field [0001] The invention relates to a thermos cup, in particular to a thermos cup capable of rapid cooling. Background technique [0002] The thermos cup is a cup that can keep the temperature of the drinking water in the cup changing slowly. The thermos cup comprises a cup body and a cup cover. Thermos cups include double-layer thermos cups, vacuum thermos cups and foam thermos cups. The cup body of the double-layer thermos cup includes an inner layer, an outer shell and a gap layer (gap) between the inner layer and the outer shell. The inner layer of the double-layer vacuum flask is where drinking water is placed. The gap layer of the double-layer thermos cup is filled with air, the air density is small, and it is not easy to transfer heat, so it is the thermal insulation material. The air in the gap layer of the double-layer thermos cup is drawn out to form a vacuum, and this thermos cup is a vacuum thermos cup. The vacuum insulation of the vacuum insulat...

Problems solved by technology

[0004] The above-mentioned rotary-adjustable quick-cooling thermos cup can quickly cool the drinking water in the cup, which can satisfy the urgent needs of those who are extremely thirsty, but there are still many defects: first, this thermos cup has an inner cup, an outer cup, and threads, and the structure is complicated; secondly, , When drinking water in the cooling cup, the inner cup needs to be twisted, and it is inconvenient to screw on and off; moreover, the inner cup and the outer cup are threaded to seal the cooling brine between the inner cup and the outer cup.

Ordinary double-layer thermos cups include a cup body and a cup cover. The cup body includes an inner layer, an outer shell, and a gap (gap) between the inner layer and the outer shell. thermos cup
