Mobile Toilet Assembly and Manufacturing Process

The assembly and manufacturing process of mobile toilets can be divided into three typical models based on different production methods: individual handmade production, factory standardized production, and modular assembly. The specific processes are as follows:

I. Individual Handmade Assembly Process

1. Basic Structure Construction
   Using a water storage tank or container as the core body, an opening is created by cutting the tank with an angle grinder to serve as the interior space of the toilet. A support structure is built using wooden strips or a metal frame to increase the overall height to match human usage requirements. Universal wheels are installed at the bottom to enable mobility, while ensuring that the load-bearing capacity of the wheels matches the self-weight of the toilet.

2. Functional Component Installation
   A drainage pipe is installed through a hole drilled at the bottom of the tank to form a floor drain structure, connecting to the toilet and securing the water tank. A three-way connector is used to enable water sharing among multiple devices, such as connecting to a showerhead and a sink. In some cases, a homemade spray-type showerhead is made from a water pipe, requiring stable water pressure. All pipe connections must be reinforced with sealant or pipe clamps to prevent leakage.

3. Wall and Roof Construction
   Plastic soft panels or composite boards are inserted into the metal frame to form the walls, with the upper part of the water storage tank inverted to serve as the roof, balancing waterproofing and lightweight requirements. A rectangular opening is cut as the doorway, and hinges and wooden boards are used to make the door, ensuring smooth opening and closing and good sealing performance.

4. Detail Handling
   Wooden strips are painted with waterproof paint to enhance durability. Glass glue is used to seal the joint between the toilet and the floor to prevent odor diffusion. A stainless steel sink is fixed by drilling a hole in the pipe cap, with a drainage hole reserved and connected to a hose leading to the floor drain. The overall structure must undergo stability testing to avoid tilting or shaking.

II. Factory Standardized Production Assembly Process

1. Box Frame Welding
   Metal profiles (such as stainless steel or galvanized steel) are welded into shape, ensuring stable welding processes and uniform welds to prevent deformation during lifting and transportation. The frame structure must comply with mechanical design principles, with its load-bearing capacity verified through pressure testing.

2. Wall and Floor Treatment
   Corrosion-resistant composite boards are used for the walls, and the floor is treated for waterproofing and anti-slip properties, with a drainage outlet reserved. The drainage outlet must be connected to municipal pipelines or septic tanks, with sealing rings installed at the connections to prevent leakage. The floor slope must be reasonably designed to ensure smooth drainage.

3. Internal Configuration Installation
   Toilets (such as squat toilets or sit toilets), flushing systems (tank-type/direct-drain type/foam-sealing type), sinks, exhaust fans, and other components are installed according to functional requirements. The electrical system uses waterproof wiring, equipped with leakage protection switches and moisture-proof lighting fixtures to ensure electrical safety. All components must be connected to the box using fixing brackets or bolts to prevent loosening during transportation.

4. Quality Inspection Process
   Structural stability tests (such as load-bearing tests), flushing system tests (such as water pressure and flow verification), electrical safety tests (such as insulation resistance tests), and water tightness tests (such as water spray tests) are conducted. Qualified products must be labeled with information such as model, load-bearing capacity, and production date, and accompanied by a user manual.

III. Modular Mobile Toilet Assembly Process

The overall assembly is completed by splicing columns and securing them with fixed clips, with all components (such as walls, roofs, and equipment modules) seamlessly connected like building blocks, eliminating the need for complex civil engineering works. Sealing strips or rubber pads are used between modules to fill gaps, ensuring wind and rain resistance. After assembly, functional linkage tests must be conducted, such as verifying the coordination between the flushing and drainage systems.
