Foam Mobile Environmental Toilet

The foam mobile environmental 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 water and electricity conservation, low maintenance costs, and significant odor prevention, suitable for locations without drainage facilities.

Core Technology and Working Principle
The core components of the foam mobile environmental toilet include a foaming cylinder, a liquid storage tank, and a liquid level balancing tank, which stabilize the foaming liquid volume through the U-tube principle and generate a long-lasting foam layer in conjunction with compressed air. Its working principle involves mixing a foaming agent with water to produce foam, replacing traditional water flushing. The foam achieves cleanliness by lubricating feces and sealing the drainage outlet, while also blocking the diffusion of odors. In 2024, a utility model patent further optimized the technology by introducing water-free foaming technology, integrating a fecal biochemical processor that utilizes microbial bacteria to decompose feces and construct a circulating water system, achieving a water-saving rate of over 99% and nearly zero water usage.

Performance Characteristics 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, significantly lower than traditional toilets.
2. Significant odor prevention: The foam layer effectively seals the drainage outlet, inhibiting the overflow of odors and improving the usage environment.
3. Low maintenance costs: The simplified equipment structure reduces cleaning frequency, and the small amount of foaming agent used makes long-term use economical.
4. Strong adaptability: Lightweight building materials are used for easy mobility and installation; it operates stably in a wide temperature range from -40℃ to 50℃, with some models equipped with a constant temperature system that can withstand temperatures as low as -45℃, suitable for extreme climates.

Application Scenarios and Types
This toilet is suitable for locations without drainage facilities, such as scenic spots, construction sites, and large event venues. There are various types on the market, for example:

• Vacuum foaming waterless restroom: Combines a microbial treatment system to achieve harmless decomposition of feces without the need for an external water source.
• Basic foaming toilet: Relies on foaming liquid for flushing, suitable for short-term or low-frequency usage scenarios.
  Prices vary significantly depending on configuration and functionality, with common models ranging from 5605 yuan to 12000 yuan, allowing users to choose according to their needs.

Technological Upgrades and Environmental Significance
Through patent improvements, the foam mobile environmental toilet has transitioned from "water-saving" to "water-free," combining microbial technology to achieve resource recycling, significantly reducing reliance on municipal water supply and drainage systems, aligning with green building and sustainable development concepts, and representing an important practice in the environmentalization of public facilities.
