National Invention Patent Mobile Toilet

Currently, there is only one publicly disclosed national invention patent related to mobile toilets, which is the 'A Mobile Toilet' applied for by Shaanxi Construction Engineering Group Corporation Limited and Shaanxi Construction Engineering Group No.12 Construction Co., Ltd. Here are the specific details:

Basic Patent Information
The application number for this invention patent is CN202610489692.3, the publication number is CN122236176A, and the publication date is June 19, 2026.

Technical Features and Innovations

1. Double-Decker Bus Carrier Design: Using a double-decker bus as the mobile carrier, the first floor is equipped with an excreta storage unit and an emergency module, while the top is fitted with prefabricated sanitary compartments. This design fully utilizes the three-dimensional space of the bus, ensuring functional integrity while enhancing the flexibility and mobility of the mobile toilet.
2. Sequential Batch Operation Components: Internally configured with an automatic lid-flipping mechanism and a film bag packaging unit, these components enable automated processing of excreta. The automatic lid-flipping mechanism reduces odor diffusion, while the film bag packaging unit minimizes pollution risks through sealed packaging, facilitating subsequent cleaning and transportation.
3. Modular Design: The modular structure improves turnover rates and reduces costs. For example, sanitary compartments and storage units can be independently disassembled and replaced, facilitating maintenance and upgrades to meet the needs of different scenarios.

Differences from Other Patents

• Utility Model Patents: For instance, the 'An Environmentally Friendly Mobile Public Toilet' (application number CN202322206423.6) focuses on the application of lightweight environmentally friendly materials and solar power supply systems, representing structural improvements. The 'A Water-Saving and Environmentally Friendly Mobile Toilet' (application number CN202521814732.4) reduces odor emissions through baffle structures and degradable materials, representing localized functional optimizations. Neither involves innovative breakthroughs in overall structure or operational methods.
• Design Patents: For example, the 'Mobile Toilet' (application number CN202430803558.8) only protects the product's shape design and does not involve technical solutions.

Core Value of the Invention Patent
This patent addresses issues such as low space utilization, inefficient cleaning, and high costs in traditional mobile toilets through carrier innovation, automated processing, and modular design, demonstrating high technical creativity and meeting the requirements for 'significant technological progress' in invention patents.
