Functional Requirements for Mobile Toilets
The functional requirements for mobile toilets cover multiple aspects, including basic sanitation, environmental adaptability, environmental control, water supply and drainage, power systems, convenient maintenance, additional configurations, safety, environmental protection, and structural components.
Basic sanitation functions are the core, providing a toilet space equipped with squat toilets or sit toilets, flushing devices, and toilet paper holders. Some high-end models use automatic induction flushing systems to avoid contact with bacteria and comply with hygiene and epidemic prevention standards. Toilet materials vary, such as ceramic and stainless steel, with flush valves available in foot-operated or induction types, and water tank capacities ranging from 5 to 10 liters. The handwashing system includes sinks, faucets, and water storage tanks, with faucets mostly being push-type or induction-type, and sink materials being ceramic or stainless steel.
In terms of environmental adaptability, mobile toilets can be quickly deployed on different terrains. Their outer shells are made of waterproof and rust-proof materials to ensure normal use in rainy or humid environments, with a service life of 3-5 years, and some products with sturdy materials can last up to twenty years.
The environmental control system includes ventilation, lighting, and temperature control. The ventilation system is equipped with a high-power exhaust fan, with a power of 20-50 watts, and an air exchange rate of 10-15 times per hour. Some products adopt a dual exhaust design. The lighting system uses LED energy-saving lamps, with a power of 5-15 watts, and some are equipped with emergency lights. The temperature control system is optionally equipped with insulation materials, electric heaters, or small warm air blowers in cold regions, and ventilation skylights or small air conditioners are installed in hot regions.
In the water supply and drainage and power systems, the water supply system is divided into self-contained water tank types (with a clean water tank capacity of 100-300 liters) and external water source types. The traditional sewage discharge system has a sewage tank at the bottom (with a capacity of 200-500 liters) that requires regular pumping. Modern environmentally friendly products use foam sealing or microbial degradation technology. The power system usually adopts a 220V mains power supply or is powered by built-in batteries and solar panels.
For convenient maintenance design, there are sewage tanks and clean water tanks at the bottom, and the tank bodies can be hoisted and transported as a whole. The interior is equipped with detachable toilets and sinks for easy cleaning and repair. Some models are equipped with emergency lights and ventilation systems.
Additional functional configurations are provided according to scene requirements, such as hot water handwashing stations with insulation layers, solar power supply systems, and facilities for the disabled. Some high-end toilets are equipped with air fresheners and aroma systems.
Safety and environmental protection features include anti-leakage designs, with the circuit system complying with national safety standards. They are equipped with odor control devices and sealed sewage discharge systems to avoid odor diffusion and environmental pollution. Sewage can be purified through professional treatment equipment for resource reuse.
In terms of structure and components, there are safety door locks inside and "Occupied/Unoccupied" indicator locks or LED displays outside. The wall panels are made of high-density polyethylene, fiberglass, or color-coated steel plates, and the floors are made of anti-slip floors or fiberglass floor grilles. For special populations, handrails, wheelchair turning spaces, and low-level handwashing stations are provided.
