Mobile Toilet Patent
Mobile toilet-related patents encompass various types, each with distinct structural designs and advantages. Here is a detailed introduction:
A Mobile Toilet (Utility Model, Patent Number CN93204722.X): This patent was applied for on March 4, 1993, and the publication/announcement date was November 3, 1993. It consists of an outer wall, a sewage storage tank, a toilet bowl, a flushing water tank, a hot air furnace, legs, and insulation layers. The outer wall has a sewage storage tank at the bottom, with a toilet bowl inside connected to the tank. A flushing water tank is installed above the toilet bowl, and a hot air furnace is also housed within the outer wall. The bottom has legs, and the top and side panels are equipped with insulation layers. The advantage of this mobile toilet lies in the inclusion of a hot air furnace and insulation layers, enabling year-round outdoor use, even in northern winters where the sewage storage tank will not freeze. Additionally, the design of the legs facilitates easy relocation to areas with high foot traffic.
A Mobile Toilet (Publication Number CN122236176A, Application Number CN202610489692.3): The publication date is June 19, 2026, and the application date is April 14, 2026. It pertains to the field of mobile toilet technology and uses a double-decker bus as its carrier. The ground floor is equipped with an excreta storage unit and an emergency module, while the top is fitted with prefabricated sanitary compartments. Inside these compartments, there are sequential batch operation units, including a sealed box, an automatic lid-flipping mechanism, and a membrane bag packaging mechanism. This mobile toilet significantly enhances turnover rate and maintenance convenience through its prefabricated modular sanitary compartments and sequential batch operation process. The vertical space layout of the double-decker bus maximizes carrier volume utilization, meeting the continuous usage needs of dense crowds while reducing equipment installation and maintenance costs through its modular structure.
Seres' 'Vehicle-Mounted Toilet and Vehicle' Utility Model Patent (Authorization Announcement Number CN224104011U): Applied for on April 22, 2025, and the authorization announcement date is April 10, 2026. It provides an emergency toilet device that can be stowed beneath a vehicle seat, consisting of a toilet body and a slide rail assembly. The slide rail assembly comprises a fixed rail and a sliding rail, with the fixed rail installed on the upper part of the toilet body and the sliding rail featuring a seat connection structure for attaching to the vehicle seat. This patent fully 'embeds' the toilet within the idle space beneath the seat, achieving true 'invisibility'. It represents a further advancement in integration and concealment, being the closest to a practical vehicle-mounted toilet solution currently available.
