Outdoor Small Mobile Toilet

An outdoor small mobile toilet is a facility that can be moved as a whole, providing toilet services for the public and customers, suitable for places with fixed or temporary needs.

I. Basic Components An outdoor small mobile toilet is typically composed of core components such as a fecal sewage storage tank (or disposal device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device. Among them, the fecal sewage storage tank is used to collect excrement. Some models are equipped with waterless flushing suction or dry packing devices to reduce water consumption. The walls are mostly made of materials such as metal carved panels and galvanized steel frames, taking into account both thermal insulation and structural strength. The roof design includes types such as pointed roofs and flat roofs to adapt to different climatic conditions. The mobile device achieves flexible transportation through lifting, towing, or power-driven methods.

II. Structural Classifications

1. By structural form: They are divided into single-unit structures and composite structures. Single-unit structures are mostly independent units, suitable for spaces with limited room. Composite structures are composed of multiple modules and can expand the number of squatting positions to meet high-traffic demands.
2. By mobility method: They include lifting and handling types and power-towing types. The lifting type relies on lifting equipment for transportation and is suitable for short-term use. The towing type is equipped with wheels or towing devices and can be transported over long distances by vehicles, suitable for touring service scenarios.
3. By sewage treatment method: They are divided into water-flushing types, waterless flushing suction types, circulating water-flushing types, and dry packing types. The water-flushing type relies on water tank供水 (water supply from a water tank), has high cleanliness but requires regular water replenishment. The waterless flushing type treats excrement through vacuum suction or chemical degradation, with strong water-saving properties. The circulating water-flushing type uses a filtration system to purify sewage, achieving water resource reuse. The dry packing type seals excrement in replaceable containers, without the need for sewage pipes, and is suitable for areas without infrastructure.

III. Typical Cases The four-squatting-position mobile toilet produced by Dezhou Hongtu Metal Products Co., Ltd. is 4 meters long and 2.3 meters wide. It features a pointed roof design and metal carved panel exterior walls. Inside, it is equipped with men's toilet squatting positions, urinals, and column basins, with a cost of less than 20,000 yuan, combining economy and practicality. There is also a brick-patterned flat-roof model, with a galvanized steel frame as the skeleton and orange brick-patterned panels for the exterior walls. It has a service life of over 15 years, is structurally stable, and has a beautiful appearance, suitable for long-term fixed deployment scenarios.
