Toy eye and toy using same

Abstract

The present disclosure provides a toy eye. The toy eye includes a pupil area, a first thermochromatic area, an iris area, and a second thermochromatic area. The first thermochromatic area has a first color in the center of the toy eye. The first thermochromatic area is made of reversible thermochromatic material with a first discoloration temperature. The first thermochromatic area is disposed around the pupil area. The iris area has the second color. The iris area is disposed around the first thermochromatic area. The second thermochromatic area is made of reversible thermochromatic material with a second discoloration temperature. The second thermochromatic area is disposed around the iris area. The first thermochromatic area and the second thermochromatic area changes color if the temperature of the toy eye is higher than the first discoloration temperature and the second discoloration temperature.

1 . A toy eye comprising:
 a pupil area with a first color;   a first thermochromatic area, made of reversible thermochromatic material with a first discoloration temperature, disposed around the pupil area,;   an iris area with a second color, disposed around the first thermochromatic area; and   a second thermochromatic area, made of reversible thermochromatic material with a second discoloration temperature, disposed around the iris area; wherein   when the temperature of the first thermochromatic area is lower than the first discoloration temperature, the color of the first thermochromatic area remains the first color, and when the temperature of the first thermochromatic area is higher than the first discoloration temperature, the color of the first thermochromatic area changes to the second color; and   when the temperature of the second thermochromatic area is lower than the second discoloration temperature, the color of the second thermochromatic area is a third color, and when the temperature of the second thermochromatic area is higher than the second discoloration temperature, the second thermochromatic area changes to red.   
     
     
         2 . The toy eye as claimed in  claim 1 , wherein the first color is black, and the third color is white. 
     
     
         3 . The toy eye as claimed in  claim 1 , wherein the second color is selected from one of brown and blue. 
     
     
         4 . The toy eye as claimed in  claim 1 , wherein the reversible thermochromatic material of the first thermochromatic area is selected from one of metal ionic compound, inorganic salts, and liquid crystal. 
     
     
         5 . The toy eye as claimed in  claim 1 , wherein the reversible thermochromatic material of the second thermochromatic area is selected from one of metal ionic compound, inorganic salts, and liquid crystal. 
     
     
         6 . The toy eye as claimed in  claim 1 , wherein the first discoloration temperature is the same as the second discoloration temperature. 
     
     
         7 . The toy eye as claimed in  claim 1 , wherein the shape of the pupil area is circular. 
     
     
         8 . The toy eye as claimed in  claim 1 , wherein the first thermochromatic area is ring-shaped. 
     
     
         9 . The toy eye as claimed in  claim 1 , wherein the iris area is ring-shaped. 
     
     
         10 . A toy comprising:
 a chip for processing data;   a toy eye comprising:
 a pupil area with a first color; 
 a first thermochromatic area, made of reversible thermochromatic material with a first discoloration temperature, disposed around the pupil area; 
 an iris area with a second color, disposed around the first thermochromatic area; and 
 a second thermochromatic area, made of reversible thermochromatic material with a second discoloration temperature, disposed around the iris area; wherein 
   when the temperature of the first thermochromatic area is lower than the first discoloration temperature, the color of the first thermochromatic area remains the first color, and when the temperature of the first thermochromatic area is higher than the first discoloration temperature, the color of the first thermochromatic area changes to the second color;   when the temperature of the second thermochromatic area is lower than the second discoloration temperature, the color of the second thermochromatic area is a third color, and when the temperature of the second thermochromatic area is higher than the second discoloration temperature, the second thermochromatic area changes to red; and   a heat conductor with one end thereof thermally coupled to the chip, and the opposite end thereof thermally coupled to the toy eye.   
     
     
         11 . The toy as claimed in  claim 10 , wherein the first color is black, and the third color is white. 
     
     
         12 . The toy as claimed in  claim 10 , wherein the second color is selected from one of brown and blue. 
     
     
         13 . The toy as claimed in  claim 10 , wherein the reversible thermochromatic material of the first thermochromatic area is selected from one of metal ionic compound, inorganic salts, and liquid crystal. 
     
     
         14 . The toy as claimed in  claim 10 , wherein the reversible thermochromatic material of the second thermochromatic area is selected from one of metal ionic compound, inorganic salts, and liquid crystal. 
     
     
         15 . The toy as claimed in  claim 10 , wherein the first discoloration temperature is the same as the second discoloration temperature. 
     
     
         16 . The toy as claimed in  claim 10 , wherein the shape of the pupil area is circular. 
     
     
         17 . The toy as claimed in  claim 10 , wherein the first thermochromatic area is ring-shaped. 
     
     
         18 . The toy as claimed in  claim 10 , wherein the iris area is ring-shaped.
