Description

Technical Field

[0001] This utility model relates to the field of ceramic cup technology, and more specifically to a ceramic cup that can change color with temperature. Background Technology

[0002] Temperature-sensitive color-changing ceramic cups are a special type of cup. They are generally coated with a temperature-sensitive material that displays different colors or patterns at different temperatures, thus changing the appearance of the cup according to the temperature of the liquid inside. These products are not only practical, but also loved by many people for their unique visual effect.

[0003] The existing patent application "CN201620053369.3, A Double-Layer Ceramic Kettle Kit" describes a pattern made of thermochromic material on the lid; the patent application "CN202322545137.2, A Thermochromic OGTT Test Cup" describes a thermochromic coating on the outer wall of the cup body. However, both the pattern and the thermochromic coating are directly applied to the outer side of the cup wall, which makes the color-changing material easily damaged during use and results in a short service life. Utility Model Content

[0004] The purpose of this utility model is to provide a ceramic cup that can change color with temperature in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] This utility model proposes a ceramic cup that can change color in response to temperature, comprising:

[0007] Cup body;

[0008] The color-changing component is located on the outside of the cup;

[0009] The color-changing component includes a groove on the outside of the cup body, a recess in the groove, an adhesive layer fixedly attached to the groove and recess, a color-changing coating fixedly attached to the outside of the adhesive layer, and a high-temperature resistant transparent layer filled into the groove and recess and fixedly attached to the adhesive layer and color-changing coating.

[0010] As a preferred embodiment of this utility model, the groove is ring-shaped and surrounds the outside of the cup.

[0011] As a preferred embodiment of this utility model, the bottom end of the inner wall of the cup body and the bottom end of the groove are on the same horizontal plane.

[0012] As a preferred embodiment of this utility model, the groove is provided in multiple sets and is evenly distributed in the groove.

[0013] In a preferred embodiment of this invention, the coating layer is a silane coupling agent layer.

[0014] As a preferred technical solution of this utility model, the outer surface of the cup and the groove are smoothly transitioned by a high-temperature resistant transparent layer.

[0015] As a preferred technical solution of this utility model, the high-temperature resistant transparent layer is made of a hard, wear-resistant, and corrosion-resistant material.

[0016] The beneficial effects of this utility model are as follows:

[0017] By embedding the color-changing coating within the groove and shielding it with a high-temperature resistant transparent layer, the protection of the color-changing coating can be improved to increase its service life; the added adhesion layer can improve the connection strength between the color-changing coating and the high-temperature resistant transparent layer; the groove, when the high-temperature resistant transparent layer is placed into the groove, increases the contact surface of the fit and connection to improve the overall strength and reduce the possibility of loosening.

[0021] like Figures 1-2 As shown, this utility model proposes: a ceramic cup that can change color with temperature, comprising;

[0022] The cup body 1 is a cylindrical shape with an open top, and a handle is integrally fixed on the outside;

[0023] Color-changing component 2 is located outside the cup body 1;

[0024] The color-changing component 2 includes a groove 21 outside the cup body 1, a recess 22 inside the groove 21, an adhesion layer 23 fixedly attached to the groove 21 and the recess 22, a color-changing coating 24 fixedly attached to the outside of the adhesion layer 23, and a high-temperature resistant transparent layer 25 filled into the groove 21 and the recess 22 and fixedly attached to the adhesion layer 23 and the color-changing coating 24.

[0025] The aforementioned cup body 1 is made of ceramic material. During manufacturing, a groove 21 is integrally formed on the lower side of the cup body 1, and a recess 22 is integrally formed on the inner side of the groove 21. An adhesive layer 23 is pre-formed on the inner side of the groove 21 and the recess 22 to improve the bonding strength when the color-changing coating 24 is subsequently applied. When applying the color-changing coating 24, if... Figure 2 As shown, a temperature-sensing coating is provided on one side of the groove 21 near the inside of the cup body 1. The remaining space of the groove 21 and the recess 22 is filled by a high-temperature resistant transparent layer 25 to connect and fix the adhesive layer 23 and the color-changing coating 24, thereby providing shielding and good protection. When warm water is filled into the cup body 1, the color-changing coating 24 changes color in response to temperature and can be observed through the high-temperature resistant transparent layer 25.

[0026] The reinforcement layer 23 is a silane coupling agent layer (such as γ-aminopropyltriethoxysilane, which has high temperature resistance); the high-temperature resistant transparent layer 25 is made of a hard, wear-resistant, and corrosion-resistant material to improve protection. The high-temperature resistant transparent layer 25 is made of epoxy resin (such as bisphenol F type epoxy resin, which has high temperature resistance) to provide better shape stability.

[0027] The groove 21 is ring-shaped and surrounds the cup body 1. The ring shape can improve the viewing field and provide a wider viewing angle for color changes.

[0028] The bottom of the inner wall of the cup body 1 is at the same level as the bottom of the inner wall of the groove 21, which ensures that the temperature sensing function can be provided even when a small amount of water is added.

[0029] The grooves 22 are provided in multiple sets and are evenly distributed in the grooves 21. When the high-temperature resistant transparent layer 25 is placed into the grooves 21, the additional grooves 22 improve the contact surface of the fit and connection, thereby improving the overall strength and reducing the possible loosening. The multiple sets of grooves 22 evenly distributed in the grooves 21 can further improve the connection strength.

[0030] The outer surface of the cup body 1 and the groove 21 are smoothly transitioned by a high-temperature resistant transparent layer 25, such as... Figure 2 As shown, the high-temperature resistant transparent layer 25 fills the groove 21 but does not protrude or protrude outwards. In order to ensure that there is no height difference between the surface of the cup body 1 and the high-temperature resistant transparent layer 25 filling the groove 21, the opening of the groove 21 and the surface of the cup body 1 are smooth, which improves the aesthetics and the comfort of holding.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
