Novel heat-preserving cup

Abstract

The invention provides a heat-preserving cup which comprises a cup body and a cup cover, wherein both the cup body and the cup cover have inner walls made from heat conducting materials, and the peripheries of the inner walls of the cup body and the cup cover are respectively coated with first and second heat storage layers. Heat storage matters are packaged in the heat storage layers. The peripheries of the first and second heat storage layers are respectively coated with heat-preserving layers. A base is further arranged at the bottom of the heat-preserving cup. The base is internally provided with a power supply and a power supply switch. A heating layer is further arranged between the first heat storage layer and the inner wall of the cup body. The heating layer is internally provided with a heating wire which is connected with the power supply. The power supply switch is used for controlling on-off of the heating wire. The heat-preserving cup provided by the invention has the characteristic of a good lasting heat-preserving effect.

Description

technical field [0001] The invention belongs to the technical field of thermos cups. Background technique [0002] Existing thermos cups often have high requirements on the insulation layer in order to achieve a better heat preservation effect. For example, the thickness of the insulation layer is usually required to be relatively thick, and the material of the insulation layer is also required to be very high. Although this kind of thermos cup has a good effect, it has overlooked a point, that is, if the soup or water contained in it is boiled (about 100°C), when people drink it, due to the temperature being too high or too high It is hot, but it needs to be poured out again and cooled to a suitable temperature before drinking. This wastes valuable time and makes drinking inconvenient. And this thermos cup, because of the large temperature difference between the inside and outside of the cup, the heat is lost quickly, and the heat preservation is not durable. In addition...

AI Technical Summary

Problems solved by technology

Although this kind of thermos cup has a good effect, it has overlooked a point, that is, if the soup or water contained in it is boiled (about 100°C), when people drink it, due to the temperature being too high or too high It is hot, but it needs to be poured out again and cooled to a suitable temperature before drinking

This is a waste of precious time, inconvenient to drink

Moreover, this kind of thermos cup, because of the large temperature difference between the inside and outside of the cup, the heat is lost quickly, and the heat preservation is not long-lasting.

In addition, if this kind of thermos cup is directly filled with soup and water suitable for drinking temperature (such as about 40-60 ° C), it is often caused by the large temperature difference between the inside and outside of the cup, resulting in soup, water, etc. in the thermos cup. the water gets cold quickly
