Mobile Exhaust Fan Toilet
A mobile exhaust fan toilet is a sanitary facility that achieves rapid odor treatment and improves the toilet's air environment through an exhaust device. The following provides an introduction from the aspects of working principle, structural features, and advantages:

Working Principle: Taking the Beijing mobile integrated toilet as an example, it is equipped with an Internet of Things (IoT)-based sensor network, with the ammonia concentration detector being a key component. When the ammonia concentration in the toilet exceeds the set threshold, the system immediately activates the built-in negative-pressure exhaust device. The negative-pressure exhaust device generates negative pressure to accelerate the replacement of air inside the toilet, drawing out the odor-laden air and discharging it outdoors, thereby reducing the ammonia concentration in the toilet. Only when the ammonia concentration fails to decrease for 30 consecutive minutes will the system generate a maintenance work order to notify relevant personnel for further inspection and maintenance.
Structural Features: The exhaust-type toilet seat is a common sanitary fixture in mobile exhaust fan toilets, equipped with an exhaust device. The upper circumferential wall of its main body features a hollow cavity that extends to the exhaust port and is connected to the cavity through ventilation holes on the upper part of the inner wall. This unique design allows the exhaust device to directly draw in the odors produced by waste when a user is using the toilet. The odors enter the hollow cavity through the ventilation holes and are then drawn out by the exhaust device, effectively reducing indoor air pollution in the toilet.
Advantages:
- Efficient Deodorization: It can quickly draw out and discharge odors from the toilet, effectively improving the toilet's air quality and providing users with a relatively fresh and comfortable environment.
- Energy Efficiency and Environmental Protection: The design of the exhaust device emphasizes energy efficiency, achieving efficient exhaust while reducing energy consumption. Moreover, by promptly discharging odors, it reduces the use of chemical deodorizers, making it more environmentally friendly.
- Intelligent Management: With the help of an IoT sensor network, it enables real-time monitoring and intelligent control of the toilet's air quality. It can automatically start or stop the exhaust device based on changes in ammonia concentration, improving management efficiency and precision.
