Simple Portable Toilet

The simple portable toilet can be achieved through the modification of water storage barrels or tanks, with core steps including structural construction, functional module installation, and mobile device configuration. The following provides an in-depth explanation from three dimensions: production methods, structural composition, and classification.

I. Common Production Methods

1. Water Storage Barrel Modification Method

   • Basic Structure: Split a water storage barrel in half, construct a mobile base using wooden planks and universal wheels, and increase the barrel's height with wooden strips to expand the internal space.
   • Functional Modules: Create an entrance on the side of the barrel and install a door frame with sponge strips, embed plastic soft panels to form walls; use the upper part of the barrel as the roof, apply waterproof paint to enhance aesthetics; drill a hole at the bottom to install a drainpipe as a floor drain, and connect a small water storage device (such as a plastic bucket) on the side for water supply.
   • Sanitary Facilities: Place a toilet and secure the water tank, connect the shower and sink inlet pipes via a three-way joint, extend the drainpipe to a sewage bucket to achieve water circulation or direct drainage.

2. Water Storage Tank Stacking Method

   • Mobile Base: Fix universal wheels at the four corners of a拖板 (trailer plate), and place a recycled water storage tank as the main body.
   • Tank Processing: Cut the top of the water storage tank to create an opening, stack two tanks and secure them with self-tapping screws, and cut a rectangular opening as the entrance.
   • Internal Installation: Drill a hole in the floor to install a drain elbow, secure the toilet and seal the gaps; use wall clips to fix water pipes and faucets, install a stainless steel basin below as a sink; connect the toilet water tank, shower hose, and spray-type showerhead to complete washing and toilet functions.
   • Door Design: Create a door using wooden planks and hinges, and install a door handle for opening and closing.

II. Structural Composition

A portable toilet typically consists of six core modules:

• Fecal Treatment System: Includes storage tanks or dry-packing devices for collecting excreta.
• Flooring: Made of slip-resistant and easy-to-clean materials to ensure safety during use.
• Sanitary Ware: Toilets or squat pans, equipped with water tanks or flushing devices.
• Walls and Roof: Constructed with lightweight materials (such as plastic panels or wooden planks) to form an enclosed space, with the roof requiring waterproofing.
• Washing Facilities: Sinks, faucets, and showers, with some models equipped with small water storage tanks.
• Mobile Devices: Universal wheels, trailer plates, or towing devices to support manual handling or mechanical towing.

III. Classification Methods

1. By Structural Form:
   • Single-Unit Structure: Independent units suitable for single users or small-scale scenarios.
   • Composite Structure: Multiple modules combined, expandable into multiple toilet stalls or with added management rooms.
2. By Mobility Method:
   • Lifting/Handling Type: Relies on forklifts or manual handling, suitable for short-term use.
   • Powered/Towing Type: Equipped with engines or towing hooks, can be towed by vehicles, suitable for long-distance transportation.
3. By Sewage Treatment:
   • Water-Flush Type: Requires connection to a water source, flushes excreta into storage tanks or municipal sewage networks.
   • Waterless Suction Type: Uses vacuum pumps to suction feces, reducing water consumption.
   • Recirculating Water-Flush Type: Recirculates flushing water through filtration and disinfection systems, suitable for water-scarce areas.
   • Dry-Packing Type: Excreta enters degradable bags, which are replaced periodically, requiring no water source.

The production of simple portable toilets should balance functionality and portability, with material selection emphasizing durability and environmental friendliness. Classification selection should be based on usage scenarios, water source conditions, and transportation needs.
