Foam Flush Portable Toilet

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

Core Working Principle
The foam flush portable toilet employs devices such as a foam generator, liquid storage tank, and liquid level balancing tank. It uses the U-tube principle to stabilize the amount of foaming liquid and generates a long-lasting foam layer with compressed air. The foaming agent, when mixed with water, produces foam that replaces traditional water flushing methods. The foam can block the sewage outlet and lubricate feces, enabling efficient flushing. 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%.

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 kilowatt-hours, significantly lower than traditional toilets.
2. Effective odor control: The foam layer effectively blocks the diffusion of odors, reducing odor pollution.
3. Low maintenance costs: The water-free foaming technology reduces dependence on water resources, and the biochemical processor lowers the difficulty of fecal treatment, extending the service life of the equipment.
4. High adaptability: Lightweight building materials are used for easy mobility and installation. The toilet can operate within a wide temperature range (-40°C to 50°C), making it suitable for extreme climatic conditions.
5. Outstanding environmental protection: The microbial bacteria decomposition technology achieves harmless treatment of feces, and the circulating water system reduces sewage discharge.

Application Scenarios
It is primarily suitable for locations without drainage facilities, such as scenic spots, construction sites, and temporary event venues. Its mobility allows it to quickly meet temporary or short-term usage needs while avoiding environmental pollution caused by drainage issues in traditional toilets.

Market Products and Prices
There is a wide variety of products on the market, including stainless steel foam squatting toilets, foam-blocking toilets, and integrated ecological toilet foam squatting toilets. Prices vary significantly depending on the brand and configuration. For example, some foam-flushing eco-toilets are priced at 1600 yuan, while foam-blocking portable eco-toilets are priced at 3200 yuan. Users can choose the appropriate model based on their actual needs.
