Intelligent safety control device for household gas cooker

Abstract

The invention relates to an intelligent safety control device for a household gas cooker. The intelligent safety control device comprises a digital control circuit and a control valve assembly. The control circuit is composed of a human body infrared induction module, a touch induction key circuit, a digital display and circuit, a voltage stabilizing circuit, a flame detection circuit, a motor driving circuit, an alarm circuit and a central processing unit (CPU) control circuit unit. Power is supplied to the digital control circuit through a battery pack. The control valve assembly is composed of a micro direct current deceleration motor, a gear assembly, a microswitch and a manual control valve body. The control valve assembly can serve as an executing mechanism controlled through a CPU as well as reserving a function of an existing gas cooker, and returning to an original zero position is achieved after instructions are finished and an air valve is closed. The intelligent safety control device is simple in structure and practical, intelligent control and electromechanical control are introduced, the shortcoming that the existing gas cooker cannot automatically close a fire is overcome, safety supportability for gas cooker use in kitchen operation is greatly improved, and fires caused by dry burning of a pot or gas leakage are avoided to the largest extent.

Description

technical field [0001] The invention relates to a gas stove safety control device, in particular to an intelligent safety control device for a family gas stove. Background technique [0002] At present, digitization has entered the kitchens of most families, such as microwave ovens, induction cookers, and CNC pressure cookers; The application of energy "gas" in digitalization is a big gap, and there are very few related products with single functions. Although most gas stoves now have electronic ignition and automatic ignition devices, the main switch fire and time control still use manual methods. For people living in a fast-paced modern life, work and entertainment are the main rhythms, and it is impossible to be on duty in front of the stove. Therefore, gas stoves often burn dry pots and burnt pots during use, and even cause fires; especially for middle-aged and elderly people living alone The family, or the owner is engaged in writing, scientific research, busy busines...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects that the existing household gas stoves cannot be automatically turned off after a delay, cannot be identified to automatically turn off the fire in various dangerous situations, have no intelligent recognition function, and cannot independently and automatically control the left and right furnace mouths; provide a An intelligent safety control device for a family gas stove that has the functions of identifying whether there is an operator in front of the stove to judge whether to automatically turn off the fire and alarm, and effectively improving the safety of the gas stove in kitchen operation
