Slow cooling cup

Abstract

The invention discloses a slow cooling cup which comprises a cup body. The cup body comprises a main cup body and a cup rim part. The main cup body comprises an inner layer and an outer layer which are connected through the cup wall. A solution and / or a liquid mixture are / is arranged in space formed between the inner layer and the outer layer. The solution and / or the liquid mixture contain / contains crystal salt and / or a dispersing agent and / or a nucleating agent. A shell is arranged at the outer side or the local part of the outer layer. A scalding-preventing heat insulating sleeve is arranged on the outer wall of the shell. The slow cooling cup is simple in structure and has a fast hot water cooling function, and when water temperature is lowered to the range of the water temperature suitable for users to drink, the slow cooling cup has a slow cooling function; as the scalding-preventing heat insulating sleeve is arranged on the outer wall of the shell, scalding is effectively prevented, and the slow cooling cup has a heat insulating function, and is high in practicality and suitable for used and popularized for wide groups of people.

Description

technical field [0001] The invention relates to a water cup, in particular to a slow cooling cup. Background technique [0002] In daily life, the cup is an indispensable daily necessities. For thousands of years, the style of the cup has been changing. With the development of science and technology, many new forms of expression have been derived. The double-layer thermos cup is one of them. However, because of its low cooling speed, when people are thirsty and urgently need to drink water, they need to wait for a long time for the water to cool down naturally or cold water to cool down, which cannot meet people's needs. At present, there are also fast cooling cups on the market, but they need to be placed In the refrigerator, the temperature difference after cooling is used to cool the hot water. Although the cooling is achieved, the effect is not fast enough, the cooling range is uncontrollable, and the operation is inconvenient, causing some difficulties and troubles to l...

[0002] In daily life, the cup is an indispensable daily necessities. For thousands of years, the style of the cup has been changing. With the development of science and technology, many new forms of expression have been derived. The double-layer thermos cup is one of them. However, because of its low cooling speed, when people are thirsty and urgently need to drink water, they need to wait for a long time for the water to cool down naturally or cold water to cool down, which cannot meet people's needs. At present, there are also fast cooling cups on the market, but they need to be placed In the refrigerator, the temperature difference after cooling is used to cool the hot water. Although the cooling is achieved, the effect is not fast enough, the cooling range is uncontrollable, and the operation is inconvenient, causing some difficulties and troubles to life. The present invention is because the solution And / or the liquid mixture contains a dispersant or nucleating agent, which can effectively control the number and particle size of crystals, and absorb heat to achieve the effect of rapid cooling of hot water. The dispersant is a kind of lipophilic and Hydrophilic surfactants with two opposite properties can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the same time prevent particles from settling and agglomerating, forming the amphiphile required for stable suspensions Dispersants can reduce the aggregation of solid or liquid particles in the dispersion system. Adding dispersants and suspending agents is easy to form dispersions and suspensions, and the functional dispersants that maintain the relative stability of the dispersion system are generally divided into inorganic dispersants and There are two types of organic dispersants. Commonly used inorganic dispersants include silicates (such as water glass) and alkali metal phosphates (such as sodium tripolyphosphate, sodium hexametaphosphate and sodium pyrophosphate, etc.). Organic dispersants include Triethylhexyl phosphoric acid, sodium lauryl sulfate, methyl amyl alcohol, cellulose derivatives, polyacrylamide, gull gum, fatty acid polyethylene glycol ester, etc.
