Abstract
The utility model discloses a control circuit for a toilet smell gas self-cleaning device. The control circuit is used for solving the technical problem of automatic control of an existing toilet smell gas cleaning device. The control circuit comprises a system power supply, a smell gas sensor, a micro-controller, an amplifying circuit, an analog-to-digital conversion circuit, an exhaust relay, an inhaling relay and a disinfecting relay. The system power is started, the smell gas sensor continuously detecting the concentration signal of the smell gas in the toilet, the signal is transmitted to the micro controller through the amplifying circuit and the analog-to-digital conversion circuit, and the open and the close of the exhaust relay, the inhaling relay and the disinfecting relay are controlled by the micro controller. As the smell gas sensor is used for automatically detecting smell gas, the toilet smell cleaning device is intelligently controlled. As the control circuit works under the condition that the content of smell gas exceeds the preset value, so that power consumption is low, the requirements of energy conservation and emission reduction are met, and use cost is reduced.
