Three-Squat-Toilet Mobile Restroom

A three-squat-toilet mobile restroom refers to an independent mobile compartment equipped with three squat-toilet units, characterized by its 'mobility' and 'multi-squat-toilet combination'.

Structural Features

1. Main Frame and Compartment:
   Constructed from lightweight yet sturdy materials (such as galvanized steel sheets, aluminum alloys, or high-strength composite materials), it offers rust resistance, corrosion resistance, and impact resistance, suitable for outdoor environments. The compartment emphasizes airtightness, thermal insulation, and waterproofing, with ventilation windows or exhaust fans installed inside to maintain air circulation. For example, some products use a galvanized steel frame structure paired with high-density sun-blocking panel exterior walls, or a galvanized square steel frame with metal carved panel designs.

2. Squat-Toilet Units:
   The three squat toilets are typically arranged side by side or separated according to the compartment's shape. Each unit includes a squat toilet, a flushing device (or a waterless system), and a partition door. The partition doors are equipped with locking mechanisms to ensure privacy, with a compact layout and independent functionality.

3. Waste Disposal System:

   • Storage Tank Type: A storage tank (septic tank) is placed beneath the squat toilets or shared among them, using a small amount of water for flushing or employing degradants and deodorizers to reduce odors, requiring regular pumping and cleaning.
   • Recirculating Water Flush Type: A small water tank and a recirculating water treatment system filter and disinfect the flushing water, saving water but with a more complex structure.
   • Dry/Packaging Type: Mechanical devices package the waste in biodegradable plastic bags or use foam to seal the toilet bowl opening, eliminating the need for water but requiring regular replacement of waste bags or replenishment of foaming agents.

4. Auxiliary Facilities:
   These include lighting systems (possibly powered by solar energy), handrails, hooks, storage shelves, toilet paper holders, etc. Some products are fully equipped with water and electricity fixtures, such as gray aluminum alloy exterior doors.

Usage Advantages

1. Mobility: Prefabricated as a complete structure, it does not require fixed underground sewage pipes and can be hoisted or towed by transportation vehicles to any location, allowing for quick relocation after use.
2. Practicality: Rationally arranging three independent toilet units within a limited space alleviates toilet pressure during peak times and improves usage efficiency. Compared to single-pit mobile restrooms, the three-squat-toilet design strikes a balance between service capacity and structural compactness, avoiding issues of excessive size and difficulty in movement due to too many pits.

Application Scenarios

Widely used in temporary events (such as exhibitions, music festivals), construction sites, parks, green spaces, and public places with limited space (such as scenic spots, campsites), meeting short-term or mobile toilet needs.
