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 to achieve 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 traditional water flushing:

• Flushing Mechanism: The foam lubricates the feces and blocks the drainage outlet. It utilizes the principle of the U-shaped tube to stabilize the amount of foaming liquid and generates a long-lasting foam layer with compressed air to achieve fecal flushing.
• Odor Blocking: The foam covers the surface of the feces, forming a sealing layer that effectively blocks the diffusion of odors.
• Water-Free Technology: A utility model patent in 2024 proposed a water-free foaming technology that integrates a fecal biochemical processor. It decomposes feces through microorganisms and builds a circulating water system, achieving a water-saving rate of over 99% and further reducing dependence on water resources.

Main Features

1. Water and Electricity Conservation: The water consumption per person is 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. Significant Odor Prevention Effect: The foam sealing layer effectively isolates odors and improves the usage environment.
3. Low Maintenance Cost: The amount of foaming agent used is small, the equipment structure is simple, and the failure rate is low.
4. Easy Mobility: It adopts lightweight building materials (such as steel frame structures and all-aluminum materials) or modular design, which is convenient for transportation and installation. It is suitable for places without drainage facilities such as scenic spots, construction sites, and temporary event venues.
5. Strong Environmental Adaptability: It has a wide operating temperature range and can work normally in environments from -40°C to 50°C, meeting the needs of extreme climatic conditions.

Technological Upgrades and Extended Functions

Some high-end models are equipped with digital intelligent hardware devices that can monitor parameters such as the amount of foaming liquid and electricity in real-time, enabling automated management. In addition, after integrating the fecal biochemical processor, the system can recycle water resources and reduce sewage discharge, which is in line with the concept of green environmental protection.

Application Scenarios

Due to its advantages of water conservation, odor prevention, and easy mobility, the foam-type mobile toilet is widely used in:

• Public places such as tourist attractions and parks;
• Areas without fixed drainage facilities such as construction sites and temporary event venues;
• Extreme climates or remote areas to solve the problem of the difficult deployment of traditional toilets.
