Mobile Toilet with Water Tank

Currently, there is no standardized finished product for a 'mobile toilet with a water tank', but similar functions can be achieved through modular design or modification. Here are some specific ideas:

1. Simple Solution Based on Bucket Modification

Referring to the case of cutting and modifying buckets, a high-strength plastic bucket can be selected as the main structure, and the following design can be used to achieve the function of a water tank:

1. Water Storage Module: Install a water pipe connector on the side wall of the bucket, connect an independent water storage bucket (such as a green bucket) as a clean water source externally, and connect it to the sink or flushing device through a hose.
2. Drainage Module: Set up a drainage pipe at the bottom of the bucket, connect it to a floor drain or sewage collection bag to ensure rapid drainage of wastewater; reserve a showerhead interface on the top bucket cover to meet flushing needs.
3. Structural Optimization: Add a partition inside the bucket to separate the water storage area from the fecal collection area to avoid cross-contamination; install wheels or handles on the outside to improve mobility.
   Applicable Scenarios: Temporary events, field operations, and other scenarios with relatively low hygiene requirements, but regular sewage cleaning and water replenishment are required.

2. Integrated Modular Design

Referring to the conventional composition of mobile toilets, the function of a water tank can be achieved by upgrading the water tank module:

1. Water Tank-Sink Combination: Transform the traditional water tank into a double-layer structure, with the upper layer as a sink and the lower layer as a water storage tank, and supply water through a water pump for circulation; or connect an independent sink externally and connect it to the main water tank through pipes.
2. Sewage Separation System: Add an independent sewage tank to collect sink wastewater, separate it from the fecal sewage tank to reduce treatment difficulty; the sewage tank can be designed as detachable for easy transportation.
3. Optimization of Mobile Stability: Use lightweight materials (such as an aluminum alloy frame) to reduce the overall weight, and add anti-slip feet or lockable wheels at the bottom to ensure safety during use.
   Applicable Scenarios: Scenic spots, construction sites, and other scenarios that require long-term use, but regular maintenance of water pumps, pipes, and other equipment is required.

3. Modular Folding Design

Drawing on the space adjustment idea of tidal toilets, the sink can be designed as a detachable or folding structure:

1. Folding Sink: Made of silicone or plastic material, it can be unfolded and fixed during use and folded for storage when idle to reduce space occupation; equipped with a retractable hose to adapt to different height requirements.
2. Quick Assembly Structure: The main frame adopts a snap-on connection, and modules such as the sink and water tank can be quickly assembled and disassembled for easy transportation and deployment; add standardized interfaces to support external water sources or sewage discharge.
   Applicable Scenarios: Emergency rescue, large-scale events, and other scenarios that require rapid deployment, but the durability of the materials must be ensured to cope with frequent assembly and disassembly.

Key Design Points: It is necessary to balance water storage capacity, drainage efficiency, and mobile stability, give priority to selecting corrosion-resistant and easy-to-clean materials, and reserve space for equipment maintenance.
