Sealing Foam Mobile Toilet

The sealing foam mobile toilet is a new type of energy-saving and environmentally friendly toilet that utilizes low-moisture foam for fecal flushing and odor blocking. Its core principles and features are as follows:

1. Working Principle and Core Devices
This toilet employs devices such as a foam generator, liquid storage tank, and liquid level balancing tank, using the U-tube principle to stabilize the amount of foaming liquid. Combined with compressed air, it generates a long-lasting foam layer. The foaming agent, when mixed with water, produces foam that replaces traditional water flushing methods. The foam can block the sewage outlet and lubricate feces, enabling efficient flushing. In 2024, a utility model patent further optimized the technology by introducing a water-free foaming technique that integrates a fecal biochemical processor. This processor uses microbial bacteria to decompose feces and constructs a circulating water system, achieving a water-saving rate of over 99%.

2. Core Advantages

• 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, significantly lower than traditional toilets.
• Significant odor control: The foam layer effectively blocks the diffusion of odors, improving the usage environment.
• Low maintenance costs: No complex drainage system is required, reducing cleaning frequency and labor costs.
• Strong adaptability: The equipment is made of lightweight building materials, facilitating easy movement and installation. It can operate within a wide temperature range (-40°C to 50°C), making it suitable for extreme climatic conditions.

3. Application Scenarios
It is primarily suitable for locations without drainage facilities, such as scenic spots, construction sites, and temporary event venues. For example, Dezhou Hongtu Metal Products Co., Ltd.'s foam-sealing toilets with fecal tanks are specifically designed for sites without water and electricity or sewage disposal. Beijing Jindongfang Environmental Landscape Engineering Co., Ltd. and Lanzhou Jintongchuang Environmental Protection Technology Co., Ltd. offer various models with price ranges of 5605 yuan to 12000 yuan and 1199 yuan to 4800 yuan, respectively, meeting different budget requirements.

4. Technology Upgrade Directions
Current technology has evolved from basic foam sealing to water-free foaming and resource recycling. By using microbial bacteria to decompose feces, it achieves zero sewage discharge and water resource recycling, further reducing environmental loads and aligning with sustainable development concepts.
