Description

Low-cost vacuum cup with variable heat insulation performance and hand warming function

Technical Field

The utility model relates to a thermos cup field specifically is a thermos cup of warm hand function is provided to variable and of low-cost thermal insulation performance.

Background

The thermos cup is a drinking tool capable of keeping the temperature of liquid contained in the thermos cup, and becomes an indispensable drinking tool in daily life of people. Most of vacuum cups on the market at present separate a heat transfer path through a vacuum layer between an inner cup body and an outer cup body, so that a good heat preservation function is realized. However, the good heat preservation function has two disadvantages: firstly, the method comprises the following steps: when the vacuum cup is used at a lower temperature, even if hot water is filled in the vacuum cup, the temperature of the outer wall of the cup is still lower, which does not meet the requirement of ergonomics; secondly, the method comprises the following steps: the hot water heat dissipation in the thermos cup is too slow, and hot water keeps at higher temperature for a long time, and inconvenient people drink, and people if want to drink, then need open the bowl cover heat dissipation, but the thermos cup can not portable this moment, has the risk of empting moreover, and the daily drinking water of giving people brings inconvenience.

At present, a phase-change vacuum cup is also available on the market, hot water in the cup can be rapidly cooled to a temperature at which people can drink after the hot water is filled in the cup, and then the water in the cup is normally kept warm. Although the vacuum cup is convenient for people to drink, the function is too single, the heat insulation performance cannot be changed according to the requirement of a user, and the selling price of the vacuum cup is far higher than that of a common vacuum cup due to high cost.

Detailed Description

The present invention will be described in detail with reference to the drawings, and it should be understood that the described embodiments are only some embodiments, but not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to the attached drawings, the vacuum cup with variable heat preservation performance and the function of warming hands at low cost comprises a cup cover 1, an outer cup 3, an inner cup 4, an outer magnet 5 and an inner magnetic rubber ring 6. The inner cup 4 is sleeved in the outer cup 3, and the inner magnetic rubber ring 6 is sleeved between the inner cup 4 and the outer cup 3. The inner magnetic rubber ring 6 has good sealing performance, the cavity between the inner cup 4 and the outer cup 3 is divided into an upper part and a lower part, the lower part is a vacuum cavity 7 which can cut off heat transmission, and the upper part is communicated with the outside through the small hole 2 on the outer cup 3 and can exchange heat with the outside. The cross section of the inner magnetic rubber ring 6 is concave, and the position of the small hole 2 on the outer cup 3 corresponds to the concave part in the middle of the inner magnetic rubber ring 6. After the inner thread of the cup cover 1 is completely meshed with the outer thread of the inner cup 4, a gap is still arranged above the small hole 2 at the top of the outer cup 3 and is communicated with the outside.

After a user holds hot water in the inner cup 4, the position of the inner magnetic rubber ring 6 can be changed by moving the position of the outer magnet 5 up and down, so that the volume of the vacuum cavity 7 is changed, and the purpose of changing the heat preservation performance of the vacuum cup is achieved. When the outer magnet 5 is not positioned at the uppermost part of the vacuum cup, the surface temperature of the part of the outer cup 3 positioned above the outer magnet 5 is equal to the temperature of the hot water in the inner cup 4, a user can cover the surface of the part with hands to obtain the function of warming hands, and the temperature of the hot water in the inner cup 4 can be sensed at the same time, so that the user is prevented from being scalded due to mistakenly drinking water with too high temperature under the condition that the temperature of the hot water in the inner cup 4 is not known. When the outer magnet 5 is positioned at the uppermost part of the vacuum cup, the user can still sense the temperature of the hot water in the inner cup 4 by sensing the temperature of the outer magnet 5.

Finally, it should be noted that: the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the technical solution of the present invention, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: those skilled in the art can still modify or easily conceive of changes in the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
