Problems solved by technology

Existing ventilation fans generally need to be turned on and off manually. Therefore, in real life, it often happens that people leave and forget to turn off the ventilation fan (or turn it on all day regardless of whether ventilation is needed), resulting in a waste of electric energy or artificially closing it prematurely. Ventilation fans (especially the toilets are often turned on whe

Abstract

The invention provides an intelligent ventilating fan. The intelligent ventilating fan comprises a power module, a PLC module, an air quality monitoring module and a fan blade driving module. The power module provides electric energy for the PLC module, the air quality monitoring module and the fan blade driving module. The air quality monitoring module is used for detecting the current indoor airquality and transmitting the detected parameter to the PLC module. A power supply circuit, connected with the fan blade driving module, of the power module is provided with a first switch and a second switch. The first switch is connected with the second switch in series. The second switch is a single-pole double-throw switch. The PLC module outputs a first signal to control the first switch to be switched on or off. The PLC module outputs a second signal to control the switch-on direction of the second switch. The intelligent ventilating fan can be automatically turned on or off according tothe current indoor environment, manual operation is replaced, and therefore electric energy is saved and the indoor air is effectively purified.

Description

technical field [0001] The invention relates to the field of ventilating fans, in particular to an intelligent ventilating fan. Background technique [0002] Ventilation fans are installed indoors and are usually used to replace indoor air to perform functions such as ventilation, dehumidification, and detoxification. Existing ventilation fans generally need to be turned on and off manually. Therefore, in real life, it often happens that people leave and forget to turn off the ventilation fan (or turn it on all day regardless of whether ventilation is needed), resulting in a waste of electric energy or artificially closing it prematurely. Ventilation fans (especially the toilets are often turned on when people enter, and the people have to leave before the odor is discharged) so that the indoor air is not effectively purified, and most of the bathrooms are gas-fired water heaters. The accident of high carbon monoxide poisoning and death happened because the ventilation fan ...
