Foam-Flush Environmentally-Friendly Mobile Toilet

The foam-flush environmentally-friendly mobile toilet is a new type of energy-saving and environmentally-friendly toilet that uses low-water-content foam to achieve fecal flushing and odor blocking. Its core principles, technical features, and application scenarios are as follows:

1. Core Working Principles
This toilet mixes a foaming agent with water through a foaming device and uses compressed air to generate a long-lasting foam layer. The foam has high lubricity and sealing properties, replacing traditional water-flushing methods: on the one hand, it reduces friction between feces and the toilet surface through lubrication to achieve flushing; on the other hand, it blocks the sewage outlet with the foam layer to prevent odor diffusion. Its core devices include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. It uses the U-tube principle to stabilize the amount of foaming liquid, ensuring continuous and stable foam generation. In 2024, a utility model patent further optimized the technology, introducing a water-free foaming technology that integrates a fecal biochemical processor. This processor decomposes feces through microorganisms and builds a circulating water system, achieving a water-saving rate of over 99%.

2. Technical Features and Advantages

• 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, far lower than that of traditional water-flush toilets.
• Significant odor control: The foam layer effectively isolates odors, and combined with microbial decomposition technology, it creates an odor-free environment.
• Low maintenance costs: The water-free design reduces the need for sewage discharge and treatment, and the biochemical processor can extend the service life of the equipment.
• Strong adaptability: It uses lightweight building materials, making it easy to move and install; it has a wide operating temperature range (-40°C to 50°C), suitable for extreme climates.
• Outstanding environmental protection: The water-free technology reduces water consumption, and microbial decomposition achieves harmless treatment of feces, avoiding secondary pollution.

3. Application Scenarios and Product Types
It is mainly used in areas without drainage facilities, such as scenic spots, construction sites, and temporary event venues. Market products include:

• Single-unit water-free intelligent foam-sealing toilets: These use water-free intelligent technology to block odors and mosquitoes with a foam layer, eliminating the need for water flushing.
• Supporting equipment: Such as 304 stainless steel integrated foaming squat toilets (priced between 1976.0 and 2090.0 yuan) and environmentally-friendly foam-sealing liquids (20kg package priced at 171.0 yuan), supporting customized needs.
• Overall mobile toilets: Priced between 5605.0 and 12000.0 yuan, offering diverse choices based on different configurations.

4. Technological Development Trends
Current technology has evolved from basic foam flushing to water-free circulating systems. In the future, it may further integrate intelligent monitoring (such as automatic warnings for low foam liquid levels) and modular design (for easy and quick assembly and disassembly) to enhance user experience and environmental benefits.
