Safety protection device for gas stove

Abstract

The invention relates to a safety protection device for a gas stove. The device at least comprises an infrared induction module and a timekeeping module. After igniting, an electromagnetic valve is switched on, the infrared induction module detects a human body spectrum within a range in real time and sends a signal to the timekeeping module, and then the timekeeping module begins timing; the infrared induction module detects the human body spectrum in the range once again and sends the signal to the timekeeping module; the timekeeping module judges the time interval between two detection signals, or if the timekeeping module judges that the value of the time between two adjacent detection signals is more than the preset value 1, and sends a signal to a main control module, a caution light flickers, and an alarm apparatus rings; and if the timekeeping module judges that the value of the time interval between the two adjacent detection signals is more than the preset value 2, the main control module sends the signal to the electromagnetic valve, then the electromagnetic valve is closed, a gas pipeline is closed, and a fire is quenched automatically.

Description

technical field [0001] The invention relates to a gas cooker, in particular to a gas cooker safety protection device. Background technique [0002] Gas stoves can be said to be closely related to our lives. Boiling water and cooking are inseparable from gas stoves. [0003] In history, the Frenchman Philip Ruben was the first to develop a gas stove. On September 21, 1799, he obtained the patent right for a dual-purpose device for lighting and heating with gas. The following year, Ruben installed the device at his own expense in a restaurant in Paris. Because the gas stove developed by Ruben at that time would emit an unpleasant smell, it was not popular at the beginning and could not be promoted. Nevertheless, he continued to study and improve the device with great enthusiasm. In 1804, on the day of Napoleon's coronation, Ruben was murdered in a Parisian street, and the development of the gas stove was interrupted. [0004] The world's first gas cooker for kitchen cookin...
