Plastic Portable Toilet Production Tutorial

The production of a plastic portable toilet requires several steps, focusing on the construction of the basic structure, installation of functional components, and detail optimization. Here is a detailed tutorial:

1. Basic Structure Construction

1. Bucket Modification: Select a large-capacity plastic bucket (e.g., over 200L). Use an angle grinder or cutting machine to horizontally cut the bucket at one-third of its height, keeping the bottom as the main body and reserving the top part for later use. Install four universal wheels (or sliding devices) at the bottom to ensure mobility.
2. Heightening and Door Frame Construction: Fix wooden strips around the bucket body, heightening it to an appropriate height (usually 1.8-2 meters). Use wooden boards to wrap the cut opening to form a door frame. The width of the door frame should match common door panels (e.g., 50-60cm) for easy subsequent installation.
3. Top Covering: Invert the upper part of the cut plastic bucket onto the top of the bucket body. Reinforce the connection with iron sheets or aluminum-plastic panels, ensuring the overlapping part exceeds 10cm to prevent peeping or rainwater infiltration.

2. Functional Component Installation

1. Drainage System:
   • Drill a hole (about 3cm in diameter) on the side of the bucket bottom, connect a drainage pipe, and install a valve switch. Use a tee to divert the flow to a spray head (for cleaning), toilet water supply, and sink.
   • Key Points: The drainage pipe should be inclined at 5-10 degrees to avoid water accumulation; the valve should be made of corrosion-resistant materials (e.g., PVC or stainless steel).
2. Water Storage Device:
   • Modify another plastic bucket as a water storage tank by drilling holes in the middle-upper and bottom parts of the bucket body and installing water pipe connectors. Use PVC pipes to make a showerhead to control water flow to the sink or toilet.
   • Optimization Suggestion: The water storage tank can be hung on top of the toilet to utilize gravity for pressurization, reducing the need for a water pump.
3. Toilet Installation:
   • Reserve a toilet interface in the middle of the bucket bottom, connect it to a septic tank (or sealed bucket) with PVC pipes, and fill the gaps with epoxy resin glue to fix the toilet and prevent air leakage or seepage.
   • Note: The septic tank needs regular cleaning, and a detachable design is recommended.

3. Detail Optimization

1. Appearance Treatment: Paint the wooden boards with anti-corrosion paint or white paint to unify the appearance and extend the service life.
2. Top Heightening: Install aluminum-plastic panels to extend the top, increasing the internal space; fix the door panel to the door frame with hinges and test the smoothness of opening and closing.
3. Water-Saving Design: The drainage from the sink can be introduced into the urinal flushing system (if a urinal is designed) to achieve water resource recycling.

4. Creative Expansion Solutions

1. Wall-Mounted Urinal: Cut the water outlet of the plastic bucket into a trapezoid, install an arc-shaped flush valve, and fix it below the sink to save space and facilitate cleaning.
2. Mobile Commode Toilet: Use PVC pipes to splice a base frame, add sliding wheels, wooden footrests, handrails, and a backrest, suitable for people with mobility issues.

Precautions:

• Wear goggles and gloves when cutting the plastic bucket and grind the edges to prevent cuts.
• Seal the water pipe connections with strong glue or pipe caps and test for 24 hours without leakage before use.
• Adjust the structure according to actual needs (e.g., whether a water storage tank or toilet type is required) to ensure a balance of functionality and practicality.
