Monolithic Plastic Mobile Toilet Structure

The structure of a monolithic plastic mobile toilet mainly consists of three parts: the feces collection device, the water supply and flushing system, and the ventilation and deodorization equipment, while also involving material selection and overall design optimization.

Feces Collection Device

The feces collection device is the core functional module, employing two mainstream technologies: Vacuum technology rapidly extracts excrement through a negative pressure system, significantly reducing water consumption (saving about 80% of water compared to traditional toilets), making it suitable for water-scarce environments. Microbial degradation technology utilizes specific bacteria to decompose organic matter, converting it into harmless substances such as carbon dioxide and water, eliminating the need for external sewage pipes and leaving no lingering odors. Both technologies employ sealed designs to prevent leakage and ensure hygiene and safety.

Water Supply and Flushing System

The water supply system is typically equipped with a small water storage tank (with a capacity of 50 - 200 liters) and a water-saving flush valve, allowing the water consumption per flush to be controlled within 1 - 3 liters. Some high-end models integrate a rainwater collection module, which filters rainwater through roof gutters and stores it in the tank, supplementing the water source and reducing dependence on municipal water supplies. The flush valve is designed with foot-pedal or sensor-based operation to avoid cross-contact infections, while achieving efficient cleaning through high-pressure nozzles.

Ventilation and Deodorization Equipment

The ventilation system creates a negative pressure air circulation through a top exhaust fan, achieving 6 - 8 air changes per hour to quickly expel odors. For deodorization, activated carbon filters are used to adsorb volatile organic compounds, or photocatalytic oxidation technology (such as titanium dioxide coatings) decomposes odor molecules into harmless substances. Some models feature a nano-coating on the inner walls of the toilet bowl, which reduces dirt adhesion through physical adsorption, further minimizing odor generation.

Material and Structural Design

The main structure is made of fiberglass-reinforced plastic (FRP) or high-density polyethylene (HDPE), both of which are corrosion-resistant, UV-resistant, and lightweight (with a density of approximately 0.9 - 1.8g/cm³), and have a recyclability rate of over 90%. The internal partitions use antibacterial-coated composite materials (such as silver-ion-containing polypropylene) to inhibit bacterial growth, reducing cleaning frequency by 50%. The exterior walls integrate solar photovoltaic panels (with a power output of 50 - 200W) to supply electricity to LED lighting, exhaust fans, and other equipment, achieving energy self-sufficiency. The overall design controls the height (2.2 - 2.5 meters) and width (1.1 - 1.3 meters) for easy truck transportation; the bottom is equipped with adjustable feet and forklift slots to ensure ground adaptability and rapid deployment capabilities.
