Introduction to Foam-Sealed Mobile Toilets

Foam-sealed mobile toilets are a new type of energy-saving and environmentally friendly toilet that utilizes low-water-content foam for fecal flushing and odor blocking, suitable for locations without drainage facilities. Its core principle involves generating a long-lasting foam layer over the toilet bowl through a foaming device, using the lubricity and sealing properties of the foam to complete flushing while blocking the spread of odors. The following provides an introduction from four aspects: technical composition, core advantages, technological breakthroughs, and application scenarios:

I. Technical Composition and Working Principle
The core components of this toilet include a foaming cylinder, liquid storage tank, liquid level balancing tank, and compressed air system. The foaming liquid is stably supplied through a patented U-shaped tube liquid level balancing system, ensuring precise foaming volume of 0.04 liters per person per use. Compressed air mixes the foaming liquid with water to generate a foam layer covering the toilet bowl. Its lubricity pushes feces into the fecal storage tank, while its sealing property forms the first layer of odor barrier. The drainage outlet is sealed with flexible materials, and combined with the rapid decomposition effect of microbial flora in the fecal storage tank, a three-layer odor control system of 'foam coverage-flexible sealing-biodegradation' is established.

II. Core Advantages

1. Extreme Water and Electricity Conservation: The water consumption per person is only 0.04 liters, with a water-saving rate exceeding 98%. After equipping with a circulating water system, the comprehensive water-saving rate reaches over 99%. The daily electricity consumption does not exceed 0.2 kWh, significantly reducing operational costs compared to traditional toilets.
2. Significant Odor Control Effect: The measured ammonia concentration in the toilet is below 0.1 ppm, meeting indoor air quality standards. Microbial flora can decompose over 90% of organic matter within 24 hours, reducing odor generation.
3. Low Maintenance Costs: The microcomputer intelligent control system automatically monitors foam residue and activates the crushing device at set times, reducing maintenance costs to 5 yuan worth of foaming agent and 2 kWh of electricity per month. The frequency of waste removal is reduced by 80%, saving 60% in comprehensive operational costs.
4. Strong Environmental Adaptability: Lightweight building materials are used for easy mobility and installation. The operating temperature range covers -40°C to 50°C, and it can operate stably at altitudes of 5,000 meters or under conditions of a Level 9 typhoon, with an operational cost of only 0.02 yuan per person.

III. Technological Breakthroughs
In 2024, a utility model patent proposed water-free foaming technology, integrating a fecal biochemical processor that decomposes feces through microbial flora and constructs a circulating water system, further reducing water dependency. This technological breakthrough enables the toilet to achieve harmless treatment and resource utilization of feces without connecting to municipal drainage networks.

IV. Application Scenarios
Suitable for locations without drainage facilities such as scenic spots, construction sites, shopping malls, and urban streets, especially suitable for extreme environments like polar expeditions and temporary events. Its modular design supports rapid deployment, meeting sanitation needs in areas with high pedestrian traffic.
