Problems solved by technology

However, because the outer wall of the cup is often rubbed by external forces, after a period of use, the text or pattern will gradually fade or disappear
At the same time, most of the existing temperature-changing materials are between 20°C and 80°C. Since the water in the glass dissipates heat quickly, especially in winter, the water temperature quickly drops below 20°C. Therefore, the glass remains colored. time is short

Embodiment 1

[0016] Such as figure 1 As shown, a double-layer color-changing glass includes an inner cup 20 and an outer cup 10, and both the inner cup 20 and the outer cup 10 are cylindrical. The inner cup 20 is adhered to the bottom of the outer cup 10 by shadowless glue, and the inner cup 20 is located in the outer cup 10, and a cavity 30 is formed between the inner cup 20 and the outer cup 10. The inner wall of the outer cup 10 is sprayed with a first temperature-changing coating. The sensing temperature of the first temperature-changing coating is 20-35°C. The first temperature-changing coating can be sprayed in a pattern or cartoon pattern to increase the aesthetics of the product . The cavity 30 is provided with a phase change material. The phase change material can be a transparent phase change material, such as a paraffin phase change material. The amount of the phase change material needs to be immersed in the first temperature change coating.

[0017] In addition, there is also a ...

Embodiment 2

[0020] The difference between this embodiment and Embodiment 1 is:

[0021] Such as figure 2 As shown, the outer cup 10 is cylindrical, and the inner cup 20 is truncated. This design makes the volume of the upper part of the cavity 30 formed between the inner cup 20 and the outer cup 10 larger than the volume of the lower part. The opening of the glass cup is at the top. Therefore, the heat exchange between the liquid and air in the upper part of the glass cup is usually more intense, and the temperature is lower than that of the lower part of the liquid. The volume of the upper part of the cavity 30 is set to be larger than the volume of the lower part, and the upper part of the cavity 30 can contain more phase change materials, and the effect of heat preservation is better, thereby making up for the upper part of the glass. The temperature of the liquid is lower than the lower part of the liquid, so that the temperature received by each part of the first temperature-changeabl...

Embodiment 3

[0023] The difference between this embodiment and Embodiment 1 is:

[0024] Such as image 3 As shown, the outer cup 10 has an inverted cone shape, and the inner cup 20 has a cylindrical shape. This design also makes the volume of the upper part of the cavity 30 formed between the inner cup 20 and the outer cup 10 larger than the volume of the lower part. At the same time, the inner cavity of the inner cup 20 is stepped, that is, the upper volume of the inner wall is larger than the lower volume. On the one hand, the cup can hold more; on the other hand, because the inner wall of the upper part becomes thinner, the heat can be transferred to the upper part of the cavity 30 in time to ensure that all parts of the cavity 30 receive The temperature reached is basically the same. Compared with the second embodiment, it is easier to process the cylindrical inner wall into a stepped shape than the truncated cone shape.

Abstract

The invention belongs to the field of A47G19 / 22, and particularly discloses a double-layer color-changing glass cup. The double-layer color-changing glass cup comprises an inner glass body and an outer glass body, the inner glass body is fixed at the bottom of the outer glass body and is located in the outer glass body, and a cavity is formed between the inner glass body and the outer glass body; a first temperature variation coating is arranged on the inner wall of the outer glass body, and a phase changing material is arranged in the cavity and is immersed in the first temperature variation coating. Compared with a traditional double-layer color-changing glass cup, the phase changing material can store heat to effectively relieve fast decrease of water temperature, and the time for keeping the color of the glass cup is effectively prolonged.

Description

Technical field [0001] The invention belongs to the A47G19 / 22 field, and particularly relates to a double-layer color-changing glass. Background technique [0002] The existing double-layer cup is composed of an inner cup, an outer cup and a lid. The inner cup and the outer cup are made of transparent materials such as resin. There is a gap between the inner cup and the outer cup. The outer cup can see the text or patterns on the inner cup. At present, some double-layer cups spray the temperature-changing paint on the outer wall of the outer cup into text or pattern. When the water temperature rises, the text or pattern will show different colors or patterns as the temperature changes according to the heat conduction effect of the cup wall. pattern. However, because the outer wall of the cup is often rubbed by external forces, after a period of use, the text or pattern will gradually fade or disappear. At the same time, most of the existing temperature change materials are bet...
