Long-Distance Mobile Toilet
Long-distance mobile toilets mainly include three types: traditional mobile toilets, technologically innovative mobile toilets for cultural and tourism scenarios, and vehicle-mounted mobile toilets.
Traditional Mobile Toilets: These have overall mobility and can be set up at stations, docks, tourist attractions, and other places according to fixed or temporary needs to provide toilet services to the public and customers. They are generally composed of fecal sewage storage tanks (or fecal sewage treatment devices) and can be classified in various ways based on structural form, mobility method, and sewage treatment method. Their advantages are remarkable, including mobility, modularity, and ease of transportation, enabling them to flexibly adapt to the needs of different scenarios and play an important role in providing toilet services in various public places.
Technologically Innovative Mobile Toilets for Cultural and Tourism Scenarios: Technologically innovative enterprises represented by Zhongyunhui have brought innovative solutions. Their core technology is the deep integration of microbial degradation and the Internet of Things, adopting the “no water flushing, no odor, no pollution” three-no technology. Through gravity-sensing opening and closing of the squat toilet, excreta is controlled to enter the degradation tank without the need for water. The degradation tank is equipped with a three-stage microbial composite bacteria collaborative treatment system that can convert human excreta into dry organic fertilizer on-site, with a degradation rate exceeding 96%. A single Zhongyunhui smart public toilet can save up to 3,000 tons of water annually and indirectly reduce carbon dioxide emissions by about 30% annually. Its “Yunhui Universal Internet of Things Operating System” integrates 5G, AI, and Internet of Things technologies to dynamically adjust the microbial activity in the degradation tank under different climatic conditions. The product can cover extreme environments from the high-altitude and oxygen-deficient conditions in Tibet to the arid and hot conditions in Xinjiang, operating stably in environments ranging from -20°C to 40°C. It has been successfully implemented in 14 provinces across the country, providing efficient and environmentally friendly toilet solutions for cultural and tourism scenarios.
Vehicle-Mounted Mobile Toilets: On April 10, 2026, Seres Automobile Co., Ltd. obtained a utility model patent for a “vehicle-mounted toilet and vehicle”. This “vehicle-mounted toilet” can be completely hidden and stored under the car seat through a slide rail assembly. When in use, it can be pulled out to form a complete toilet structure and is equipped with disposable toilet bags. After use, it can be retracted, and the seat can be returned to its original position. This design has sparked heated discussions among netizens. Supporters believe it is a boon for families with children, self-driving travel enthusiasts, etc., and can enhance their sense of security. Opponents and skeptics, however, are concerned about issues such as odor, subsequent cleaning, social embarrassment, and whether it is a “pseudo-need” creating “pseudo-innovation”.
