Environmental Foam-Type Mobile Toilet

The environmental foam-type mobile toilet is a new type of energy-saving and environmentally friendly toilet that utilizes low-water-content foam for fecal flushing and odor blocking. It features water and electricity conservation, low maintenance costs, and effective odor control, making it suitable for locations without drainage facilities.

Core Working Principle

This toilet generates low-water-content foam by mixing a foaming agent with water through a foaming device. The foam, with its high lubricity and sealing properties, can replace traditional water flushing: on one hand, it lubricates feces and seals the drainage outlet, reducing friction and enabling efficient flushing; on the other hand, the foam layer covers the toilet surface, blocking odor diffusion. Its core components include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. It employs the U-tube principle to stabilize the foaming liquid volume and uses compressed air to generate a long-lasting foam layer, ensuring stable system operation.

Technical Features and Advantages

1. Water and electricity conservation: The water consumption per person is only about 0.04 liters, and the daily electricity consumption does not exceed 0.2 degrees, which is much lower than that of traditional water-flush toilets. The water-free foaming technology proposed in a utility model patent in 2024 further integrates a fecal biochemical processor, decomposing feces through microbial bacteria and constructing a circulating water system, achieving a water-saving rate of over 99% and nearly zero water consumption.
2. Odor control and hygiene: The foam layer effectively blocks odors, and when combined with microbial decomposition technology, it reduces odor generation and enhances the user experience.
3. Strong adaptability: The equipment is made of lightweight building materials, facilitating easy movement and installation, and is suitable for locations without drainage facilities such as scenic spots and construction sites. It has a wide operating temperature range and can function normally in environments from -40°C to 50°C, meeting the needs of extreme climatic conditions.
4. Low maintenance costs: The system has a simplified structure, reducing the need for pipeline maintenance compared to traditional toilets; the water-free technology lowers sewage discharge and treatment costs, resulting in significant long-term economic benefits.

Application Scenarios and Extensions

In addition to the basic environmental foam toilets, some manufacturers (such as Dezhou Hongtu Metal Products Co., Ltd.) offer foam-sealing mobile toilets with integrated fecal tanks. These toilets feature exterior walls with wood-grain finishes, stainless steel door locks, and steel structure doors, combining practicality with aesthetics. Such equipment further expands the application scenarios, meeting diverse needs such as temporary events and emergency rescue operations.
