Foam-Type Mobile Toilet

The foam-type mobile toilet is a new type of energy-saving and environmentally friendly toilet that uses low-water-content foam for fecal flushing and odor blocking. It has the characteristics of water and electricity conservation, odor prevention, and easy mobility, making it suitable for places without drainage facilities.

Core Working Principle

The foam-type mobile toilet generates low-water-content foam by mixing a foaming agent with water through a foaming device. The foam has high lubricity and sealing properties, which can replace the traditional water-flushing method:

• Flushing Mechanism: The foam covers the surface of feces, forming a lubricating layer that reduces friction and allows the feces to slide smoothly into the drainage outlet;
• Odor Blocking: The foam layer seals the drainage outlet, effectively preventing the diffusion of odors and inhibiting bacterial growth;
• Foam Stability: The U-shaped tube principle is used to control the amount of foaming liquid, and compressed air is used to generate long-lasting foam, ensuring continuous coverage.

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 degrees, which is much lower than that of traditional toilets;
2. Water-Free Technology Upgrade: In 2024, a utility model patent introduced water-free foaming technology, integrating a fecal biochemical processor. It decomposes feces through microorganisms and builds a circulating water system, achieving a water-saving rate of over 99%;
3. Significant Odor Prevention Effect: The sealing property of the foam layer is better than that of water seals, allowing for a long-term odor-free environment;
4. Low Maintenance Cost: The simplified structure reduces the need for pipeline cleaning, and the consumption of foaming agents is low;
5. Strong Adaptability: Lightweight building materials (such as steel frames and all-aluminum materials) are used for easy mobility and installation. It is suitable for a wide temperature range (-40°C to 50°C) and is ideal for scenic spots, construction sites, and other places without drainage facilities.

Structure and Materials

• Core Devices: Include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc., which generate foam through compressed air;
• Smart Hardware: Some models are equipped with digital devices such as indicator lights to monitor the equipment status in real-time;
• Material Selection: Steel frames enhance stability, while all-aluminum materials reduce weight and improve corrosion resistance.

Application Scenarios

The foam-type mobile toilet is particularly suitable for the following scenarios:

• Temporary Events: Such as music festivals, sports events, and other short-term gathering places;
• Areas without Infrastructure: Remote scenic spots, wild construction sites, and other environments lacking drainage systems;
• Extreme Climate Regions: It can operate stably in extremely cold or hot environments.

This technology continues to be upgraded through patent optimization, balancing environmental protection needs with practicality, and becoming an important innovation direction for modern public sanitation facilities.
