Double-layer heat-preservation thermal-insulation cylindrical cup

Abstract

The invention provides a double-layer heat-preservation thermal-insulation cylindrical cup which is characterized in that the cylindrical cup comprises an inner sleeve and an outer sleeve which are provided with upward openings, the inner sleeve is placed in the outer sleeve, opening edges of the inner sleeve and the outer sleeve are connected and sealed to form a hollow interlayer cavity, and the interlayer cavity is filled with large-specific-heat-capacity liquid; the inner sleeve is a conductor good at transferring heat, and the outer sleeve is a conductor not good at transferring heat. According to the double-layer heat-preservation thermal-insulation cylindrical cup, firstly, a double-sleeve structure is utilized, an interlayer is arranged between water and the outer wall of the cup, and heat dissipation is made to be more moderate; secondly, pure water and other liquid with the large specific heat capacity are used to serve as intermediate energy storage, heat of hot water can be effectively absorbed and then transmitted to human hands in a secondary level, and the heat dissipation speed can be lowered to the maximum degree so as to obtain relatively longer heat preservation time. The double-layer heat-preservation thermal-insulation cylindrical cup is simple in structure, clever in conception, very low in cost and suitable for being used for daily life and living.

Description

technical field [0001] The invention relates to a container for holding liquid, in particular to a double-layer thermal insulation cylinder cup. Background technique [0002] In winter, after we add hot water to the cup, we hold the cup in the palm of our hand to keep warm. At this time, the temperature of the hot water is directly transmitted to the human body through the wall of the cup, which not only easily causes burns to the hands, but also quickly dissipates the heat through the wall Yes, the heating time is relatively short. In this regard, two issues need to be considered: first, how to prevent the temperature of hot water from being directly transmitted to the human body to protect human hands; second, how to make full use of the heat of the water body so that people can have a longer heating time. Contents of the invention [0003] In order to overcome the problems mentioned in the background technology, the present invention proposes a double-layer thermal ins...
