Novel intelligent home sterilization, disinfection and odor-removal device

The invention discloses a novel intelligent home sterilization, disinfection and odor-removal device. The device comprises a poisonous gas detecting control circuit and an intelligent liquid-crystal display controller. The poisonous gas detecting control circuit is used for detecting the content of poisonous gases in a living space in real time to obtain the measured value of the content of the poisonous gases and then sending the measured value of the content of the poisonous gases to the intelligent liquid-crystal display controller in real time. The intelligent liquid-crystal display controller is used for receiving the real-time poisonous gas content measured value sent by the poisonous gas detecting control circuit and displaying the poisonous gas content measured value; whether the poisonous gas content measured value at the present moment is larger than a starting standard threshold value or not is judged, and if yes, an air purifying device is automatically controlled to start to execute an air purifying operation; whether the poisonous gas content measured value at the present moment is lower than a halting standard threshold value or not is judged, and if yes, the air purifying device is automatically controlled to stop from executing the air purifying operation.
