Mobile Foam Toilet
The mobile foam toilet is a new type of energy-saving and environmentally friendly toilet that utilizes low-water-content foam for fecal flushing and odor blocking, featuring significant advantages such as water and electricity conservation, odor prevention, and mobility.

Core Working Principle
The mobile foam toilet employs devices such as a foaming cylinder, liquid storage tank, and liquid level balancing tank, using the U-tube principle to stabilize the amount of foaming liquid and generate a long-lasting foam layer in conjunction with compressed air. The foaming agent, when mixed with water, produces foam that replaces the traditional water flushing method. The foam not only seals the sewage outlet to block odors but also lubricates feces for easy discharge. In 2024, a utility model patent further optimized the technology by introducing a water-free foaming technique that integrates a fecal biochemical processor. This processor utilizes microbial bacteria to decompose feces and constructs a circulating water system, achieving a water-saving rate of over 99% and enabling zero-water flushing.
Structural Composition and Features
Its structure includes a fecal sewage storage tank (or disposal device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobility device, among others. Key advantages include:
- Water and electricity conservation: The water consumption per person is only 0.04 liters, and the daily electricity consumption does not exceed 0.2 degrees, significantly lower than traditional toilets.
- Significant odor prevention: The foam layer effectively seals the sewage outlet, blocking the spread of odors and improving the usage environment.
- High mobility: Lightweight building materials are used, facilitating easy overall movement and installation, suitable for scenic spots, construction sites, and other locations without drainage facilities.
- Strong environmental adaptability: It operates stably across a wide temperature range, from -40℃ to 50℃, meeting the needs of extreme climates.
- Low maintenance costs: The simplified structure results in a low failure rate, and the water-free foaming technique reduces reliance on external water sources, further lowering operational costs.
Application Scenarios and Value
As a type of mobile toilet, the mobile foam toilet can be rapidly deployed in scenarios such as temporary events and disaster relief through modular design, addressing the toilet needs in areas without fixed drainage facilities. Its environmentally friendly characteristics align particularly well with the current concept of green development, offering significant practical value in conserving water resources and reducing pollution emissions.
