Internal Structure of Cangzhou Mobile Toilet
The internal structure of the Cangzhou mobile toilet is centered around modular design, encompassing basic functional components, a waste treatment and recycling system, an intelligent interaction unit, and customizable expansion configurations. The specific structural features are as follows:
I. Basic Functional Component Configuration
The interior space is designed with practicality in mind, integrating lighting, storage, hygiene, and safety functions. LED lighting fixtures are installed on the ceiling, providing uniform illumination with low energy consumption and long service life. The walls are equipped with stainless steel coat hooks and handrails, balancing load-bearing capacity and corrosion resistance. The side walls feature toilet paper holders and covered trash cans to minimize odor diffusion. The waste storage tank, as the core container, is made of high-density polyethylene, offering acid and alkali resistance as well as impact resistance, with capacities ranging from 100 to 300 liters depending on the model. The floor is treated with either non-slip patterned aluminum plates or convex spherical rubber mats; the former enhances friction through surface embossing, while the latter disperses pressure through an elastic structure. Both have passed national non-slip rating certifications, ensuring safety in rainy or snowy weather. The door and window system employs an aluminum alloy frame paired with a color-steel plate door, with the door frame embedded with sealing strips, achieving a sound insulation performance of over 35 decibels while meeting outdoor wind pressure resistance requirements.
II. Waste Treatment and Recycling Unit
The core treatment system adopts a closed design, achieving harmless treatment through multi-stage separation technology. The physical sedimentation unit utilizes gravity separation principles to preliminarily separate solids from liquids. The biological degradation module converts organic matter into carbon dioxide and water within 48-72 hours by adding specific bacterial strains. The chemical neutralization unit targets acidic or alkaline waste, achieving neutralization reactions through pH regulators. The treated liquid meets discharge standards through membrane filtration technology, while the solids are compressed into blocks for easy recycling. Some high-end models are equipped with a solar-assisted heating system, which raises the temperature of the treatment chamber through collector plates, accelerating microbial activity and increasing degradation efficiency by 30%.
III. Intelligent Sensing and Interaction System
The capacity sensor employs ultrasonic detection technology to monitor the liquid level in the waste storage tank in real-time. When the capacity reaches 80%, it triggers an audible and visual alarm and sends maintenance reminders to the management platform through an IoT module. The environmental sensor integrates temperature and humidity as well as ammonia concentration monitoring functions, automatically activating the exhaust system when the ammonia concentration exceeds 20 ppm. The status display adopts an LED matrix design, visually indicating 'Occupied/Unoccupied' status through red and green dual-color lights. Some models support touch operation, allowing users to query device usage records and maintenance guides.
IV. Functional Expansion and Custom Design
The insulation layer uses 8-centimeter-thick polyurethane foam sandwich panels with a thermal conductivity coefficient below 0.024 W/(m·K). Paired with a double-layer structure of a 50-sandwich color-steel plate roof, it maintains stable indoor temperatures in environments ranging from -30°C to 50°C. In terms of spatial layout, a compact design integrates a sink, squat toilet, and independent water tank within a 1.2m x 1.5m space, with a water tank capacity of 15-30 liters, supporting manual pressing or foot-pedal water outlet. Customization options cover exterior materials (metal carved panels, fluorocarbon-sprayed steel plates), functional modules (adding showerheads, exhaust fans, air conditioners), and color schemes, allowing for personalized configurations based on usage scenarios (scenic spots, construction sites, exhibitions).
