Interior Design of Dual-Body Mobile Toilets

The interior design of dual-body mobile toilets centers on the combination of two independent sanitary unit modules on a movable carrier, achieving efficient use and convenient maintenance through structural optimization and functional integration.

Structural and Material Design

The foundation of dual-body mobile toilets consists of an integrated chassis and box structure. The chassis is designed with a standard towing interface, allowing for quick connection to conventional towing equipment (such as trucks or tractors) for flexible transportation. The box is made of lightweight, high-strength composite materials (such as fiberglass or aluminum alloy), ensuring structural integrity while reducing overall weight for easy deployment. Inside, the toilet integrates a toilet bowl, water tank, ventilation, and lighting systems, with all piping embedded within the box's sandwich layer to prevent external damage. For example, some models feature modular piping design, enabling easy replacement of components by simply removing local panels during maintenance, significantly enhancing efficiency.

Sanitary Unit Functional Configuration

Each independent unit is equipped with basic sanitary facilities:

• Toilet System: Typically, water-saving squat or sit toilets are used, with some high-end models featuring vacuum suction toilets that significantly reduce water consumption (as low as 0.5L per flush).
• Water Supply System: Comprising a freshwater tank and a wastewater tank, with capacities designed according to usage scenarios. For instance, models used in scenic areas may have freshwater tanks with capacities of 300-500L, supporting 50-80 uses before requiring refilling; wastewater tanks are equipped with liquid level sensors that automatically alert when full.
• Ventilation System: Utilizing natural convection principles, air circulation is achieved through top exhaust vents and bottom intake vents; in enclosed or high-temperature environments, small axial fans (approximately 10-20W in power) are added to enhance air exchange, ensuring at least 6 air changes per hour to effectively control odors.

Sanitary Maintenance and Environmental Design

To reduce the risk of cross-infection, compartments are equipped with disposable toilet seat covers or automatic cleaning devices as standard. The former are made of paper or biodegradable plastic and are disposed of with the trash after use; the latter achieve automatic disinfection of the toilet bowl surface through high-pressure water jets or ultraviolet lights, with cleaning cycles set to every 10 uses or every 2 hours. Daily maintenance involves regularly replenishing toilet paper and hand sanitizer, and using chlorine-based disinfectants (concentrations of 500-1000mg/L) to wipe down frequently touched areas such as door handles and flush buttons. For wastewater treatment, modern models often integrate wastewater collection systems, where sewage is initially settled and then discharged through piping into dedicated collection tanks to prevent direct environmental pollution; some models are also equipped with small wastewater treatment units that filter and disinfect the wastewater before it is discharged to meet standards.
