In order to solve the above problems, the main purpose of the present invention is to provide a cup cover having a temperature reminding function, the cup cover comprising: a cover body having an upper surface and a lower surface; and a temperature sensing element disposed on the cover body And indirectly sensing the temperature of the liquid in the cup covered by the lid to display different colors according to different temperature ranges; wherein the temperature sensing element is made of at least one thermochromic material.

In one embodiment, the temperature range is between 6 and 8 ° C, 10 to 12 ° C or 36 to 75 ° C.

In one embodiment, the temperature range is between 50 and 70 °C.

In one embodiment, the temperature sensing element is disposed on an upper surface of the cover.

In one embodiment, the temperature sensing component is disposed on a lower surface of the cover, and the cover is formed of a transparent material or a translucent material.

In one embodiment, the temperature sensing element is disposed on the cover in an embedded manner.

In one embodiment, the temperature sensing element is attached to the cover in an attached manner.

In one embodiment, the temperature sensing element is disposed on the cover by printing and coating.

In one embodiment, the temperature sensing element is formed by stacking or mixing at least two thermochromic materials in multiple layers.

In one embodiment, the cup cover further includes an air hole and an outlet portion, and the air hole is disposed at one end of the cover body at a distance from the temperature sensing element The upper surface and the lower surface of the cover body are disposed at the other end of the cover body opposite to the position at which the air hole is disposed and communicate with the upper surface and the lower surface of the cover body.

When using the cup lid with the temperature reminding function, when the cup is filled with the high temperature liquid, the high temperature energy of the liquid can be transmitted to the lid through the conduction, and the temperature sensing element on the lid can be indirectly sensed. To the liquid temperature to display the color corresponding to the liquid temperature at that time. The user only needs to look at the color of the temperature sensing element on the lid of the cup to know the current liquid temperature and determine whether it is suitable for drinking, and can achieve the effect of preventing burns and accidents.
