Inside a Movable Toilet

The interior facilities of movable toilets are designed around the needs of hygiene, convenience, and durability, primarily including the following core modules:

1. Core Sanitary Fixtures

1. Toilets: Mainly ceramic squat toilets or sit-down toilets, with high-end products using stainless steel and equipped with foot-operated or sensor-operated flush valves, with water tank capacities ranging from 5 to 10 liters. Some products are equipped with child safety seats or toilet rings for special populations.
2. Handwashing Systems: Standard handwashing basins (ceramic or stainless steel, width 30-40 cm), push-button or sensor-operated faucets, and water storage tanks. Some high-end models are equipped with hand dryers or disinfectant dispensers.
3. Auxiliary Accessories: Including mirrors, coat hooks, storage shelves (boards), toilet paper holders, and trash cans. Accessible toilets are additionally equipped with low-position handwashing basins (height ≤ 80 cm) and emergency call buttons.

2. Environmental Control Systems

1. Ventilation Systems: Utilize 20-50 watt powerful exhaust fans to ensure 10-15 air changes per hour. Some products enhance air circulation through dual exhaust designs on the top or side walls, reducing odor retention.
2. Lighting Systems: Primarily use 5-15 watt LED energy-saving lights, with some products equipped with emergency lights (battery life ≥ 2 hours) to ensure basic lighting during power outages.
3. Temperature Control Systems: In cold regions, insulation materials (such as polyurethane foam) or electric heaters (power 200-500 watts) are installed; in hot regions, ventilation skylights or small air conditioners (cooling capacity 1-2 horsepower) are set up to maintain internal temperatures between 15-30°C.

3. Water Supply, Drainage, and Electrical Systems

1. Water Supply Systems: Divided into self-contained tank types (clean water tank capacity 100-300 liters, supplied by pumps or gravity) and external water source types (directly connected to municipal water pipes).
2. Sewage Systems: The traditional method uses a bottom sewage tank (capacity 200-500 liters), requiring regular pumping; environmentally friendly types use foam sealing (saving 90% water) or microbial degradation technology (no sewage discharge required).
3. Electrical Systems: Priority is given to connecting to 220V mains power, with remote areas using 12V/100Ah batteries or solar panels (power 200-500 watts) to support the operation of exhaust fans, lighting, and sensor devices.

4. Structural and Safety Design

1. Materials and Flooring: Wall panels are made of high-density polyethylene (HDPE), fiberglass, or color-coated steel plates (thickness ≥ 3 mm), with the floor laid with anti-slip flooring or fiberglass grating (friction coefficient ≥ 0.6).
2. Door Locks and Indicators: Internally equipped with safety door locks (preventing accidental opening), and externally equipped with 'Occupied/Vacant' indicator locks or LED displays (red/green indicating status).
3. Accessibility Facilities: The aisle width is ≥ 90 cm, with an internal space of ≥ 1.5 square meters, equipped with L-shaped handrails (height 75-85 cm) and wheelchair turning space (diameter ≥ 1.5 meters).
