Abstract

The invention provides a double-layer heat-preservation and heat-insulation barrel cup which is characterized in that: the device comprises an inner sleeve and an outer sleeve, wherein the inner sleeve and the outer sleeve are provided with upward openings, the inner sleeve is arranged in the outer sleeve, the openings of the inner sleeve and the outer sleeve are connected and closed to form a hollow interlayer cavity, and liquid with large specific heat capacity is filled in the interlayer cavity; the inner sleeve is a good conductor of heat and the outer sleeve is a non-good conductor of heat. The invention firstly utilizes the structure of the double sleeves to arrange an interlayer between the water body and the outer wall of the cup, so that the heat dissipation is milder; and secondly, the liquid with larger specific heat capacity, such as pure water, is used as intermediate energy storage, so that the heat of the hot water can be effectively absorbed and transferred to hands again, and the heat dissipation speed can be reduced to the maximum extent to obtain longer heating and heat preservation time combined.

Description

Double-layer thermal insulation cylinder cup

technical field

The invention relates to a container for holding liquid, in particular to a double-layer thermal insulation cylinder cup.

Background technique

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

In order to overcome the problems mentioned in the background technology, the present invention proposes a double-layer thermal insulation cylinder cup, and its specific technical scheme is as follows:

A double-layer thermal insulation sleeve cup, including an inner sleeve and an outer sleeve with an upward opening, the inner sleeve is placed in the outer sleeve, and the openings of the two are closed along the connection to form a hollow partition Cavity, the interlayer cavity is filled with liquid with large specific heat capacity; the inner sleeve is an excellent conductor of heat, and the outer sleeve is a non-excellent conductor of heat.

In one or more embodiments of the present invention, the openings of the inner sleeve and the outer sleeve are connected and closed by an annular lip, which is also a poor conductor of heat.

In one or more embodiments of the present invention, the liquid with large specific heat capacity is pure water.

In one or more embodiments of the present invention, the thermal non-excellent conductor is plastic with a thickness of 2-3 mm.

In one or more embodiments of the present invention, the excellent conductor of heat is aluminum alloy, stainless steel or iron, and its thickness is 1-2 mm.

The present invention first utilizes the double-sleeve structure to set up an interlayer between the water body and the outer wall of the cup to make the heat dissipation more moderate; secondly, the pure water and other liquids with large specific heat capacity are used as intermediate energy storage, which can effectively absorb The heat of hot water is transferred to the hands again, and the speed of heat dissipation can be reduced to the greatest extent, so as to obtain a longer heating and heat preservation time. The present invention is a product with simple structure and ingenious design, and the cost is very low. Suitable for everyday household use.

Description of drawings

Fig. 1 is a schematic structural view of the double-layer heat-insulating cylinder cup of the present invention.

Detailed ways

The scheme of this application is further described in conjunction with the accompanying drawings as follows:

A double-layer thermal insulation sleeve cup, including an inner sleeve 1 and an outer sleeve 2 with an upward opening, the inner sleeve 1 is placed in the outer sleeve 2, and the openings of the two are closed along the connection to form Hollow interlayer chamber 3, the interlayer chamber 3 is filled with liquid with large specific heat capacity; the inner sleeve 1 is an excellent conductor of heat, and the outer sleeve 2 is a non-excellent conductor of heat.

The openings of the inner sleeve 1 and the outer sleeve 2 are connected and closed by an annular lip 4, which is also a poor conductor of heat.

The liquid with large specific heat capacity is pure water. The present invention first uses the structure of double sleeves to set up a partition between the water body and the outer wall of the cup to make the heat dissipation more gentle; secondly, use pure water and other liquids with large specific heat capacity As an intermediate energy storage, it can not only effectively absorb the heat of hot water, retransmit it to the hands, but also reduce the speed of heat dissipation to the greatest extent, so as to obtain a longer heating and heat preservation time. Ingenious product at a low cost for everyday household use.

The heat non-excellent conductor is plastic, and its thickness is 2-3 millimeters.

The excellent heat conductor is aluminum alloy, stainless steel or iron, and its thickness is 1-2 mm.

The above-mentioned preferred implementation mode should be regarded as an illustration of the implementation mode of the scheme of this application, and any technical deduction, replacement, improvement, etc. that are similar to, similar to, or based on the scheme of this application should be regarded as the scope of protection of this patent.
