Abstract:
A color-changing luminous thermometer spoon (100) comprises a bowl portion (10) and a handle (20). The bowl portion (10) is provided with a temperature sensor (11). The handle (20) is provided with an IC control module (21) and a display unit device (22). The output terminal of the temperature sensor (11) is connected with the input terminal of the IC control module (21). The output control terminal of the IC control module (21) is connected with the display unit device (22). The display unit device (22) at least includes a warning signal light (221) and a temperature display screen (222). Furthermore, the edge of the bowl portion (10) is covered with a thermochromic material. When the bowl portion (10) is in a temperature range that is below a first predetermined temperature value, the thermochromic material exhibits a first color. When the bowl portion (10) is in a temperature range that is between the first predetermined temperature value and a second predetermined value, the thermochromic material exhibits a second color. Moreover, when the thermochromic material exhibits the second color, the warning signal light (221) emits light, and the temperature display screen (222) displays the temperature measured by the temperature sensor (11).
