The invention relates to the technical field of kitchen safety monitoring, and discloses a kitchen gas stove abnormity early warning system based on infrared thermal imaging multispectrum. The system comprises an infrared thermal imaging acquisition module, a dynamic feature extraction module and an abnormal behavior identification module. The infrared thermal imaging acquisition module synchronously captures the surface temperature field distribution of the gas cooking range through a multispectral infrared sensor array, obtains flame form data in combination with a visible light image, and generates a multi-channel fused infrared thermal imaging characteristic spectrum through processing. The dynamic feature extraction module adopts a three-dimensional convolution kernel to scan continuous time sequence frames, identifies flame morphological feature differences, calculates thermal radiation intensity energy distribution offset, and outputs dynamic feature vectors. The abnormal behavior recognition module extracts a correlation mode through a deep residual network, compares current features with a historical normal working condition feature library, and generates a preliminary early warning signal containing an abnormal type code and a risk level when the attenuation rate of flame spectral energy in a specific infrared band exceeds a first threshold value.

This invention relates to the field of flow regulating valves for gas appliances, and proposes a gas valve and a gas stove. The gas valve includes a valve body with an inlet channel, a first outlet channel, a second outlet channel, and a valve core mechanism. The valve core mechanism is axially movable within the valve body to selectively open or close the gas passages between the first and second outlet channels and the inlet channel, respectively. An actuator is located outside the valve body and triggers the valve core mechanism to move axially. When the actuator operates and triggers the valve core mechanism to move within a first displacement stroke, the inlet channel alone opens the first outlet channel. When the actuator operates and triggers the valve core mechanism to move from the first displacement stroke to the second displacement stroke, the inlet channel can open both the first and second outlet channels, thus enabling one actuator to regulate the gas flow of both outlet channels. This solves the technical problem that existing gas valves require multiple solenoid valves to control the inlet gas flow.
