Double-Body Mobile Toilet

The double-body mobile toilet is a sanitary facility that can be moved as a whole and is suitable for various public places, featuring flexible design, diverse configurations, and environmental protection and durability.

I. Basic Definition and Applicable Scenarios
The double-body mobile toilet is a sanitary facility that can be moved in its entirety. It is typically installed in fixed or temporary demand locations such as stations, docks, tourist attractions, and construction sites. Its core advantage lies in its 'mobility', enabling rapid deployment to areas in need and meeting both temporary and long-term usage requirements.

II. Design Features and Functional Configurations

1. Flexible Combination Design: Utilizing a double-connected structure, it allows for the free combination of functional modules, such as pairing a toilet with a shower room to meet diverse usage scenarios.
2. Space and Layout Optimization: With typical dimensions of 1.7 meters in width and 2.56 meters in length, it features a small corridor at the front and an externally placed sink, saving internal space and facilitating simultaneous use by multiple people.
3. Material and Durability: The main body often employs an aluminum alloy single door with refined interior decoration. Some products use stainless steel materials, combining lightness with corrosion resistance to extend service life.
4. Sanitation and Water-Saving Technologies: Equipped with vacuum sewage disposal technology to isolate odors, it includes separate sinks, mirrors, automatic sensor faucets, and other water-saving devices inside, enhancing the user experience and reducing water consumption.

III. Price and Market Variations
Prices vary significantly based on configurations and regions: Products from Cangzhou, Hebei range from 950 yuan per unit to 12,000 yuan per room; custom models from Chengdu, Sichuan cost around 1,200 yuan per piece; and vehicle-mounted models in Beijing cost approximately 1,780 yuan per set. Price fluctuations are primarily influenced by materials, functional modules (such as shower rooms and vacuum sewage systems), and transportation costs.

IV. Structure and Mobility Methods

1. Structural Forms: Divided into single and composite structures, composite structures enhance stability and functionality through modular design.
2. Mobility Methods: Include lifting (overall transportation via lifting equipment) and powered towing (relying on vehicle traction), adapting to different terrains and transportation needs.

V. Sewage Treatment Technologies
Multiple treatment solutions are provided: Water-flush types rely on traditional sewage pipes; waterless suction types collect waste through negative pressure; recirculating water-flush types achieve water reuse; and dry packing types require no water source, suitable for water-scarce or temporary scenarios.

VI. Design Principles and Material Selection
Adhering to the principles of 'mobility convenience, economic durability, and environmental ecology', priority is given to selecting lightweight and durable materials such as fiberglass-reinforced plastic and polyethylene, balancing structural strength with transportation convenience while reducing environmental impact.
