Foam-type Mobile Toilet

A 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.

Core Principles and Devices
The foam-type mobile toilet generates low-water-content foam by mixing a foaming agent with water, utilizing the high lubricity and sealing properties of the foam to replace traditional water flushing methods. 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 feces to form a sealing layer, which not only lubricates the feces for easy discharge but also effectively blocks the diffusion of odors. In 2024, a utility model patent further optimized the technology, proposing a water-free foaming technology and integrating 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 degrees, which is much lower than that of traditional toilets.
2. Significant odor control effect: The foam layer completely covers the drainage outlet, blocking the escape of odors from the source, eliminating the need for additional deodorizing equipment.
3. Low maintenance cost: The equipment has a simple structure and a low failure rate, and the foaming liquid can be recycled, reducing the consumption of consumables.
4. Strong environmental adaptability: It uses lightweight building materials for easy movement and installation, and has a wide operating temperature range (-40°C to 50°C), making it suitable for places without drainage facilities such as scenic spots and construction sites.

Product Types and Prices
The mainstream products on the market include stainless steel foam squatting pans, foam-sealing squatting pans, etc., all of which come with built-in foaming devices. For example:

• The stainless steel foam squatting pan from Botou Sanlong Railway Vehicle Fittings Factory is priced at 1200 yuan;
• The ecological toilet integrated foam squatting pan from Beijing Anbangjie Technology Development Co., Ltd. is priced at 1786 yuan;
• The intelligent foam anti-blocking toilet from Lanzhou Jintongchuang Environmental Protection Technology Co., Ltd. is priced at 3800 yuan.
  The price differences are mainly influenced by the material, functions (such as intelligent control), and brand. Users can choose according to their actual needs.

Application Scenarios
The foam-type mobile toilet is especially suitable for areas with scarce water resources or incomplete drainage systems, such as scenic spots in arid regions, temporary construction sites, and large-scale outdoor events. Its environmental protection characteristics also meet the current requirements for low-carbon development, making it an ideal alternative to traditional toilets.
