Abstract

Disclosed is an anti-burning reminder device arranged on a pot cover. The device is composed of a button battery, a buzzer, a chip, a metal sheet temperature sensor, a necklet and a plurality of wires. When the device is in use, the metal sheet temperature sensor is tightly attached to the pot cover, a pot cover handle is sleeved with the necklet, when the temperature of the pot cover is smaller than a certain set value, a system does not work, and electric energy of the button battery is not consumed; when the temperature of the pot cover is larger than a certain set value, a metal sheet deforms to be connected with a first control circuit, the buzzer is driven to tweet every minute; when the temperature of the pot cover is larger than another set value, the metal sheet deforms to be connected with a second control circuit, the buzzer is driven to tweet continuously, and a user is reminded to cut off a heat source. The device is easy to operate, low in manufacturing cost and high in practicability.

Description

technical field [0001] The invention belongs to an electroacoustic device, which is powered by a button battery, connects a circuit based on the heat expansion of a metal sheet, drives a buzzer to sound, and implements a reminder. Background technique [0002] Since modern kitchens use gas and electricity to cook food, and do not need manpower to add firewood, they often neglect to forget that the food is being steamed, and sometimes the food is burnt. Even the bottom of the pot fell off, which could cause a fire in severe cases. Gu Xiaoyi's patent for scorching alarm (patent number: 200910264336) uses an infrared temperature sensor to detect the temperature of the pot, and when it exceeds the set temperature value before scorching, an alarm is activated. This patent lacks a reminder function, and the system is in a state of waiting for an alarm for a long time, which consumes a lot of electricity. For this reason, it is necessary to design a circuit that does not work at ...
