Patent for 'A Mobile Toilet' applied for by Shaanxi Construction Engineering Corporation and Shaanxi Construction Engineering 12th Branch: The patent application publication number is CN122236176A, the application number is CN202610489692.3, the application publication date is June 19, 2026, and the application date is April 14, 2026. The inventors are Yang Bin, Yan Shi, Xu Bing, and Li Wenkai. The patent agency is Beijing Zhongxuntongda Intellectual Property Agency Co., Ltd., and the patent agent is Zhang Hong. This invention pertains to the field of mobile toilet technology and utilizes a double-decker bus as the carrier. The first floor is equipped with an excreta storage component and an emergency module, while the top is fitted with prefabricated sanitary compartments. Inside, there are fixed sequential batch operation components. The sequential batch operation components include a sealed box fixedly installed at the bottom of the toilet inside the prefabricated sanitary compartment. Inside the sealed box, there is an automatic flip-cover mechanism connected to the toilet's defecation port, and at the bottom of the automatic flip-cover mechanism, there is a film bag packaging mechanism. Relying on the prefabricated modules assembled into the prefabricated sanitary compartments and the sequential batch operation process, the usage turnover rate and maintenance convenience are significantly improved. The three-dimensional space layout of the double-decker bus maximizes the utilization of the carrier's volume, meeting the continuous usage needs of dense crowds while reducing equipment installation and maintenance costs through a modular structure.
Utility model patent for 'Vehicle-mounted Toilet and Vehicle' applied for by Seres: The authorization announcement number is CN224104011U. It was applied for on April 22, 2025, and the authorization process was completed on April 10, 2026. This patent provides an emergency toilet device that can be stored under the seat, consisting of a toilet body and a set of slide rail components. The slide rail components are made up of a fixed rail and a sliding rail.
