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. Its technical principles, core devices, performance characteristics, and market applications are as follows:

Technical Principles and Core 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. Its core devices include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. It employs the U-shaped tube principle to stabilize the amount of foaming liquid and uses compressed air to generate a long-lasting foam layer. The foam covers the sewage outlet to form a sealing layer, which not only lubricates the feces for easy flushing but also effectively blocks the diffusion of odors. In 2024, a utility model patent further optimized the technology by introducing a water-free foaming technology that integrates a fecal biochemical processor. This processor decomposes feces through microbial bacteria and constructs a circulating water system, achieving a water-saving rate of over 99% and enabling zero-water flushing.

Performance Characteristics

1. Water and electricity saving: The water consumption per person is only 0.04 liters, and the daily electricity consumption does not exceed 0.2 kilowatt-hours, which is much lower than that of traditional toilets.
2. Significant odor control: The foam layer seals the sewage outlet, blocking odors at the source. Some products use stainless steel foaming squatting pans, and the dense foam prevents splashing and sticking.
3. Low maintenance cost: Lightweight building materials facilitate easy movement and installation, making them suitable for places without drainage facilities. Moreover, the microbial decomposition technology reduces the frequency of fecal cleaning.
4. Strong environmental adaptability: It has a wide operating temperature range and can work stably in environments from -40℃ to 50℃, meeting the needs of extreme climatic conditions.

Market Applications and Product Selection

The mainstream brands in the market include Shengshitong, Jieshuo, Qimu, etc. Prices vary greatly depending on the brand, specifications, and configurations. For example, the unit price of some products is 1600 yuan (for orders of 100 or more pieces) and 3200 yuan (for orders of 1 or more pieces). Some high-end products are made of 304 stainless steel and are equipped with an intelligent foaming system that can automatically adjust the thickness and density of the foam to enhance the user experience. When selecting a product, it is necessary to choose the appropriate specifications according to the usage scenario (such as scenic spots or construction sites) and budget, giving priority to water-saving performance, odor control effect, and material durability.
