Mobile Toilet with Ventilation System

The design considerations for the ventilation system of mobile toilets cover five aspects: ventilation equipment configuration, exhaust vent and duct design, odor control auxiliary measures, environmental adaptability optimization, and intelligent monitoring and emergency design.

1. Ventilation Equipment Configuration
   The core equipment is a powerful exhaust fan with a power range of 20-50 watts, ensuring 10-15 air changes per hour. For example, in Xinxiang, it is recommended to equip each toilet cubicle with a small exhaust fan of ≥5W, and large toilets should use dual fans in parallel. In Luohe, it is recommended to use axial fans or centrifugal fans with an air volume of 15-20 cubic meters per minute for each toilet cubicle. Equipment selection should be based on the size of the toilet and the usage scenario, balancing energy consumption and ventilation efficiency.

2. Exhaust Vent and Duct Design
   Exhaust vents are typically located at the top or high on the side walls (≥1.8 meters), away from areas where people are active, to avoid direct sunlight and rain intrusion. Duct layout should follow the principle of being "short, straight, and smooth," with a recommended diameter of ≥10 centimeters to reduce bends and connections and minimize air resistance. For split-type toilets, the exhaust fan can be installed in an independent ventilation module, connected to the exhaust ports of each cubicle via PVC ducts. In Xinxiang, when multiple toilets are placed side by side, a centralized exhaust main duct is used, with branch ducts equipped with air volume control valves to optimize airflow distribution.

3. Odor Control Auxiliary Measures
   Install activated carbon filter pads, photocatalytic filters, or deodorizing liquid sprays in front of the exhaust fans to create a physical-chemical dual filtration system. Internally, an "upward supply, downward exhaust" airflow pattern is adopted to accelerate the removal of stale air. Regularly clean the exhaust vent filters to maintain ventilation efficiency. Some products, such as the 2026 new lightweight plastic mobile toilet, directly exhaust odors through exhaust pipes and are equipped with large-capacity clean water tanks and gravity flushing systems to reduce odor generation at the source.

4. Environmental Adaptability Optimization
   In Xinxiang, the orientation of the toilets is adjusted according to seasonal wind directions (e.g., the air intake faces southeast in summer and is sheltered from the wind in winter), and rainproof equipment with an IP54 rating or higher is selected to cope with rainy weather. In Luohe, rainproof louvers are installed at duct outlets, and mosquito nets are added at air intakes. In cold regions, insulation materials or electric heaters are installed, while in hot regions, ventilation skylights or small air conditioners are used to regulate temperature, ensuring the ventilation system operates stably throughout the year.

5. Intelligent Monitoring and Emergency Design
   In large-scale event scenarios, air quality sensors are installed to automatically activate the exhaust system when odor concentrations exceed standards, and backup power interfaces are reserved to cope with extreme weather. Intelligent monitoring can provide real-time feedback on ventilation status, reducing manual inspection costs and improving emergency response capabilities.
