Description

Metal chopstick circuit with temperature warning function

This creation is a metal chopsticks circuit with a temperature warning function, especially a metal chopsticks circuit that can detect the temperature of the metal chopstick clamping section and emit a warning light when the temperature is too high.

Chopsticks are tableware that people have used in daily life since ancient times. Its main function is to allow people to grab food into the mouth to keep their hands clean and hygienic. With the progress of the times, more and more chopsticks made of metal gradually replaced wooden chopsticks and bamboo chopsticks. Although metal chopsticks are more hygienic and environmentally friendly than wooden chopsticks and bamboo chopsticks, they have good thermal conductivity, so when they are used by people, they are easily heated by food to increase the temperature. This phenomenon is most often encountered when people eat hot pot or barbecue food. When the holding section of the metal chopsticks is heated to a high temperature, it is not easy for people to detect it, so it is possible that the mouth is not scalded when eating, which is a danger to the health of the body.

In order to improve the above deficiencies, this creation is to provide a metal chopstick circuit with a temperature warning function to detect the temperature of the metal chopstick clamping section, and emit a warning light when the temperature is too high to remind the user of the metal chopsticks Use with care to avoid scalding your mouth. This creation includes a temperature sensing element, a microcontroller, a plurality of light-emitting elements and a battery, wherein the temperature sensing element is used to detect the temperature of the metal chopsticks holding section, and send the temperature information to the microcontroller The micro controller is used to determine whether the temperature of the metal chopstick holding section is too high? If yes, further judge the degree of excessive temperature of the metal chopsticks holding section, and classify, and then output one or more high level signals to the plurality of light-emitting elements according to the level, so that the plurality of light-emitting elements have relative The number emits a warning light. The higher the temperature of the metal chopstick holding section, the greater the number of the plurality of light-emitting elements driven to emit light; the battery is used to supply power to the temperature-sensing element and the microcontroller.
