Internal Configuration of Mobile Toilets

The internal configuration of mobile toilets typically includes sanitary ware, environmental control, water supply and drainage, power systems, structural components, and other functional modules, as detailed below:

1. Core Sanitary Ware

   • Toilets: Primarily ceramic squat toilets or sit-down toilets, with high-end models using stainless steel and equipped with foot-operated or sensor-activated flush valves, with water tank capacities ranging from 5 to 10 liters. In rural areas, a common configuration is a squat toilet combined with a flush tank.
   • Handwashing Systems: Include ceramic or stainless steel sinks (width 30-40 cm), push-button or sensor-activated faucets, and water storage tanks. Rural mobile toilets often feature simple handwashing basins.
   • Other Accessories: Standard equipment includes mirrors, coat hooks, shelves, toilet paper holders, and trash cans; high-end models may add child safety seats or toilet seat covers for enhanced convenience.

2. Environmental Control Systems

   • Ventilation Systems: Equipped with 20-50 watt high-power exhaust fans, with some models featuring dual exhaust designs on the top or side walls; rural toilets often have ventilation louvers to promote air circulation.
   • Lighting Systems: Use 5-15 watt LED energy-saving lights, with some models equipped with emergency lights to ensure normal operation during power outages.
   • Temperature Control Systems: In cold regions, insulation materials, electric heaters, or small warm air blowers are installed; in hot regions, ventilation skylights or small air conditioners are added to meet different climatic needs.

3. Water Supply and Drainage, and Power Systems

   • Water Supply Systems: Divided into built-in water tank types (with fresh water tank capacities of 100-300 liters) and external water source types to meet the needs of scenarios without municipal water supply.
   • Sewage Systems: The traditional method uses a bottom sewage tank (with a capacity of 200-500 liters); environmentally friendly models adopt foam sealing or microbial degradation technology to reduce odors and pollution.
   • Power Systems: Support 220V mains power access or are powered by built-in batteries (such as 12V/100Ah) and solar panels to ensure power stability in remote areas.

4. Structural Components and Accessories

   • Door Locks and Indicators: Equipped with safety door locks inside and 'Occupied/Unoccupied' indicator locks or LED displays outside; rural toilets often use ball-type door locks.
   • Materials and Floors: Wall panels are made of high-density polyethylene (HDPE), fiberglass, or color-coated steel plates; floors use non-slip flooring or fiberglass floor grilles to enhance safety.
   • Barrier-Free Facilities: For special populations, handrails, wheelchair turning spaces, and low-position handwashing basins are provided, reflecting humanized design.

5. Other Configurations

   • Smart mobile toilets may add feces collection systems, smart mirrors (displaying weather, time, etc.), and breathing lights (adjusting brightness according to the environment) to enhance the sense of technology and user experience.
