Foam Flush-Free Mobile Toilet

The foam flush-free 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. Its core device consists of a foam generator, a liquid storage tank, a liquid level balancing tank, etc. It stabilizes the amount of foaming liquid through the principle of a U-shaped tube and generates a long-lasting foam layer with compressed air to replace the traditional flushing method.

The main features are as follows:

1. Outstanding 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. In 2024, a utility model patent further optimized the technology by integrating a fecal biochemical processor. It decomposes feces through microorganisms and builds a circulating water system, achieving a water-saving rate of over 99% and enabling nearly zero-water flushing.
2. Low maintenance costs: The lubricity of the foam promotes the sliding of excreta, reduces residues, and the small increase in the volume of emissions can reduce the frequency of clearance and related costs.
3. Significant odor control effect: The foam layer in the toilet bowl directly blocks fecal odors, and the flexible sealing device at the drainage outlet forms a secondary barrier, effectively inhibiting the diffusion of odors.
4. Wide range of applications: It does not require water supply and drainage pipes and can operate normally in extreme temperature environments ranging from -40°C to 50°C. The equipment is made of lightweight building materials, making it easy to move and install, and is suitable for areas without drainage facilities such as scenic spots, construction sites, and temporary event venues.

Working principle: The foaming agent is mixed with water in proportion to form a foaming liquid, which is then acted upon by compressed air to produce dense foam. The lubricity of the foam helps excreta slide quickly into the collection device, while the foam layer covers the drainage outlet, forming a physical sealing barrier to block the escape of odors.

Price differences: Due to differences in configurations and styles, the price ranges of products from different manufacturers vary greatly. For example, the price of the foam-flush-free cultural and tourism toilet with a management room and a disabled room from Beijing Jindongfang Environmental Landscape Engineering Co., Ltd. is 9025 yuan; the price of the foam micro-flush ceramic squatting pan intelligent environmentally friendly toilet from Beijing Anbangjie Technology Development Co., Ltd. is 2261 yuan.

This technology replaces water resources with foam and combines it with a microbial circulation system, achieving a balance between environmental protection and practicality. It is an effective solution for toilet problems in areas without drainage.
