Kunming Foam Mobile Environmental Protection Toilet
The Kunming foam mobile environmental protection toilet is an environmentally friendly mobile toilet based on foam water-saving technology, featuring water conservation, environmental protection, and strong adaptability.

Technical Principles and Composition
The foam mobile environmental protection toilet mainly consists of a stainless-steel squatting pan, a control system, and a foam generation system. Its core principle is to use a foaming agent mixed with water to produce a large amount of foam. This foam replaces traditional toilet-flushing water and effectively prevents odor diffusion by sealing the sewage outlet with foam. At the same time, this technology can convert excrement into organic fertilizer, achieving resource utilization and aligning with environmental protection concepts.
Patents and Technological Innovations
The patent for this technology was applied for by Zhao Yijun on September 9, 2005, and granted on October 25, 2006. In 2017, Yunnan Jiagu Environmental Protection Co., Ltd. further applied for related patents, promoting the localization of the technology. This continuous technological innovation provides a solid guarantee for the application of foam mobile environmental protection toilets in Kunming.
Core Features
- Outstanding Water-Saving Performance: Foam replaces toilet-flushing water, resulting in extremely low water consumption, making it particularly suitable for areas with water shortages.
- Strong Environmental Adaptability: It can operate in environments without water or electricity and has a wide operating temperature range, meeting the needs of different climatic conditions.
- Significant Environmental Benefits: Through foam sealing and the resource utilization of excrement, it reduces pollution and achieves recycling.
Industry Recognition and Application
In 2016, the foam-type water-saving toilet designed by Kunming Huiyun Luminous Engineering Co., Ltd. won the Excellent Case Award at the First National Tourism Toilet Technological Innovation Competition, demonstrating industry recognition of its technological advancement. In terms of practical application, a similar toilet was built in Nanning Qingxiu District Nanhu Park in 2017. Kunming also offers mobile toilet rental services throughout the city, including foam-sealed mobile toilets, to meet temporary or long-term usage needs.
Conclusion
The Kunming foam mobile environmental protection toilet achieves the dual goals of water conservation and environmental protection through technological innovation. Its patented technology, adaptability, and application cases all indicate that it is an effective solution in the field of public facilities, especially suitable for tourist attractions, temporary events, and other scenarios.
