Description

Technical Field

[0001] The present application belongs to the technical field of thermos cups, and in particular relates to a thermos cup capable of rapidly cooling down. Background Art

[0002] Thermos cups are daily necessities that people often use. Most of the thermos cups on the market have a vacuum layer or an insulation layer, which keeps the water temperature in the cup within a certain range through air or insulation materials, making it convenient to use. However, this type of thermos cup has a limitation, that is, it can only keep the water in the cup warm for a long time. If the water temperature is too high, it is not suitable for immediate drinking.

[0003] There are some thermos cups with cooling function on the market, such as the Cool Cooling Cup, which changes the upper layer of the thermos cup into a cooling cavity, and uses a mechanical structure switch to control the volume of the hot drink in the cavity to achieve a cooling effect. The product has a novel design, but since there are no auxiliary components for rapid cooling, the hot drink in the cooling cavity can only dissipate heat slowly, and the cooling effect is average; there is also the famous 55° cup, which uses phase change material as a heat-absorbing interlayer. Through the combination of heat transfer and phase change, it can not only cool the hot water in the cup, but also heat the cold water in the cup, so that the water temperature can reach about 55°, which is suitable for human drinking. The market prospect of this product is huge, but the thermos cup using phase change material is relatively expensive under the existing technical conditions, and there are certain safety hazards.

[0004] Patent 206641699U discloses a fast cooling cup suitable for a composite phase change material system, which has a cup body, the cup body includes a cup-shaped heat-insulating outer shell and an inner liner layer arranged in the heat-insulating outer shell, a closed cavity is formed between the inner liner layer and the heat-insulating outer shell, a wrapping layer is arranged in the cavity, and the wrapping layer divides the cavity into a closed chamber 1 and a chamber 2, wherein chamber 1 is formed between the wrapping layer and the inner liner layer, the chamber 1 is filled with alloy phase change material, and chamber 2 is filled with non-metallic phase change material; the thermos cup quickly reduces the temperature of hot water in the cup through the composite phase change material system to achieve the purpose of rapid drinking. The disadvantage of this thermos cup is that the use of phase change material can quickly cool the water in the cup, but because the cup insulation layer is only the outer shell outside the phase change layer, the insulation effect is not as good as that of the common thermos cup, and the cooled water needs to be drunk in time; and because of the addition of phase change material, the cost of the thermos cup is high, which is not conducive to the popularization of the product.

[0005] Patent CN109008537 A discloses a thermos cup that uses air flow to cool itself. The thermos cup includes an inner liner, an insulating sleeve located on the outer periphery of the inner liner, and a lid located at the upper open end of the inner liner. A heat dissipation sleeve is arranged on the outer periphery of the inner liner, and an air cold zone channel is formed between the outer periphery of the inner liner and the inner wall of the heat dissipation sleeve. Components for adjusting the air intake and air outlet are arranged at the bottom and upper part of the inner liner, respectively. By changing the air flow rate on the surface of the heat dissipation sleeve, the thermos cup can be quickly switched between heat preservation and cooling functions. The thermos cup does not require phase change materials, which reduces the production cost of the cup. However, since the insulation layer is air, the heat preservation effect is worse than that of a vacuum thermos cup. The heat dissipation sleeve has a complex structure and is prone to accumulate dust and water stains, and is not easy to clean. Although it is located on the outside of the cup body, as an item that is in direct contact with the human body, there are certain food safety risks.

[0006] Therefore, developing a product with low cost, simple structure, capable of quickly reducing the water temperature in the cup, and having good heat preservation effect and being safe and reliable is a technical problem that needs to be solved urgently. Summary of the invention
