Foam-Sealing Mobile Environmental Toilet

The foam-sealing mobile environmental 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. It has the characteristics of water and electricity conservation, low maintenance costs, and significant odor prevention, making it suitable for places without drainage facilities.

Core Principles and Technical Features

The foam-sealing mobile environmental toilet generates low-water-content foam by mixing a foaming agent with water through a foaming device. It utilizes the high lubricity and sealing properties of the foam to replace traditional water flushing. Its core components include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. It adopts the U-tube principle to stabilize the amount of foaming liquid and uses compressed air to generate a long-lasting foam layer that covers the sewage outlet, lubricating feces for easy discharge while blocking odor from escaping. In 2024, a utility model patent further optimized the technology, introducing a water-free foaming technology and integrating a fecal biochemical processor. Through the decomposition of feces by microorganisms, a circulating water system is established, achieving a water-saving rate of over 99% and enabling nearly zero-water flushing.

Performance 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-flushing toilets.
2. Significant odor prevention: The foam layer effectively seals the sewage outlet, blocking the diffusion of odors and reducing odor pollution.
3. Low maintenance costs: The amount of foaming agent used is small, the equipment structure is simple, the failure rate is low, and the long-term economic efficiency is outstanding.
4. Strong environmental adaptability: Lightweight building materials are used for easy mobile installation. It has a wide operating temperature range (-40°C to 50°C) and can withstand extreme weather conditions.

Application Scenarios

It is suitable for areas without drainage facilities or with water supply difficulties, such as scenic spots, construction sites, and temporary event venues, especially for public spaces with high environmental requirements and large foot traffic. Its mobility also allows for flexible adjustment of its position according to needs, meeting both short-term and long-term usage requirements.
