Foam Flushing Mobile Toilet

The foam flushing mobile toilet is a new type of energy-saving and environmentally friendly toilet that utilizes low-water-content foam for fecal flushing and odor blocking. Its technical principles, core devices, performance characteristics, and application scenarios are as follows:

Technical Principles and Core Devices
This toilet generates low-water-content foam by mixing a foaming agent with water, using the high lubricity and sealing properties of the foam to replace traditional water flushing. Its core devices include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. It employs the U-tube principle to stabilize the amount of foaming liquid and uses compressed air to generate a long-lasting foam layer. The foam covers the surface of the toilet bowl, forming a lubricating layer that reduces friction between feces and the bowl while blocking the sewage outlet to prevent odor diffusion. In 2024, a utility model patent further 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%.

Performance 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 kilowatt-hours, far lower than that of traditional water-flushing toilets.
2. Significant odor control: The foam layer effectively isolates odors, reduces mosquito and fly breeding, and improves the usage environment.
3. Low maintenance costs: The water-free foaming technology reduces sewage discharge, lowering the frequency of waste removal and treatment costs.
4. Strong adaptability: The equipment uses lightweight building materials, facilitating easy movement and installation. It has a wide applicable temperature range (-40°C to 50°C) and can operate stably under extreme climatic conditions.

Application Scenarios
It is suitable for places without drainage facilities or where water resources are scarce, such as scenic spots, construction sites, and temporary event venues. For example, the water-free foam-packing mobile toilet (specification 1200, material: metal carved panel) produced by Hebei Lvmei Environmental Sanitation Equipment Manufacturing Co., Ltd. has an applicable temperature range of -35°C to 50°C and a voltage of 220V, meeting different environmental requirements. Its circulating water system and microbial decomposition technology further expand its application scenarios, especially suitable for ecologically sensitive areas or long-term outdoor operations.

Extension of Technical Advantages
The water-free foaming technology decomposes feces through microorganisms, converting organic matter into harmless substances while recycling water resources to form a closed-loop system. This innovation not only solves the sewage discharge problem of traditional mobile toilets but also significantly reduces dependence on municipal sewage networks, aligning with the concepts of green buildings and sustainable development.
