Foam-Sealing Environmentally Friendly Mobile Toilet

The foam-sealing 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. It has the characteristics of water and electricity conservation, low maintenance costs, and significant odor prevention, making it suitable for scenic spots, construction sites, and other scenarios without drainage facilities.

Core Working Principle
This toilet mixes a foaming agent with water through a foaming device and uses compressed air to generate a long-lasting foam layer. With its high lubricity and sealing properties, the foam, on the one hand, lubricates the feces to allow them to slide down smoothly, and on the other hand, blocks the sewage outlet to prevent the spread of odors. Its core devices 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, ensuring a continuous and stable generation of foam.

Technical Advantages and Characteristics

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. The water-free foaming technology introduced by the utility model patent in 2024, after integrating a fecal biochemical processor, decomposes feces through microorganisms and builds a circulating water system, achieving a water-saving rate of over 99% and nearly zero water consumption.
2. Odor prevention and low maintenance costs: The foam layer effectively isolates odors and reduces the frequency of cleaning. The equipment has a simple structure and a low failure rate, resulting in significantly lower long-term maintenance costs compared to traditional toilets.
3. Strong adaptability: It uses lightweight building materials for easy movement and installation, has a wide operating temperature range (-40°C to 50°C), and can withstand extreme climatic conditions. Some models are equipped with fecal tanks and can be used independently without the need for water, electricity, or sewage pipelines, meeting the needs of places without infrastructure.

Application Scenarios
It is mainly deployed in areas lacking drainage facilities such as scenic spots, construction sites, and temporary event venues. Its mobility and environmental protection features not only reduce pollution to the natural environment but also lower infrastructure construction costs, making it a preferred option for outdoor public sanitation.

Technological Evolution
From relying on a small amount of water to assist foaming in the early stages to achieving completely water-free foaming and self-decomposition of feces through patent technology in 2024, this technology converts excreta into harmless substances through a microbial circulation system, further enhancing environmental protection and resource utilization efficiency, marking a step forward for mobile toilets towards the goal of 'zero emissions'.
