Mobile Public Toilet (su)
Mobile public toilets do not typically use 'su' as a specific identifier or model number, but their general composition and features can be introduced.

Mobile public toilets are portable and flexible public sanitation facilities designed to meet temporary or specific-scenario restroom needs. Their design emphasizes convenience, practicality, and environmental friendliness, typically consisting of several key components.
I. Main Structure The main frame of mobile public toilets is often made of steel, which offers high strength and stability, ensuring the overall structural integrity of the toilet and enabling it to adapt to different usage environments and transportation requirements. The frame walls are commonly constructed from metal carved panels, which not only provide an aesthetically pleasing appearance but also offer good thermal insulation and soundproofing properties, creating a relatively comfortable internal environment for users.
II. Internal Configuration In terms of internal configuration, the floor may be made of marble, a material that is wear-resistant and easy to clean, helping to maintain the cleanliness and hygiene of the toilet interior. For sanitary ware, ceramic squat toilets are generally provided; ceramic surfaces are smooth and less prone to residue buildup, facilitating easy cleaning and maintenance. Washbasins are also a common feature, allowing users to clean their hands after using the toilet. Additionally, some mobile public toilets are equipped with electric heaters to provide warmth in cold weather; PVC ceilings, which are moisture-resistant and fire-resistant, extending the toilet's service life; and LED ceiling lights, offering ample and energy-efficient illumination.
III. Functional Systems Mobile public toilets are also equipped with fecal sewage storage tanks or fecal sewage treatment devices to collect and treat fecal sewage, preventing environmental pollution. They are also provided with water tanks to supply water for flushing sanitary ware, ensuring the normal operation of the toilet. The mobility mechanism is another crucial component, allowing the toilet to be flexibly moved and arranged according to actual needs.
