Mobile Door Toilet
A mobile toilet is a facility that can be moved as a whole and provides toilet services to the public, with various classifications and unique designs.
I. Basic Components A mobile toilet generally consists of a fecal sewage storage tank (or disposal device), floor slab, sanitary ware, walls, washing equipment, water tank, roof, and mobile device, among others. These components work together to ensure that it has complete toilet functions while facilitating easy overall movement and placement in different locations.
II. Classification Methods
- By structural form: Mobile toilets are divided into single-structure mobile toilets and composite-structure mobile toilets. The single-structure type is relatively simple and independent, while the composite-structure type may be more complex in terms of function or spatial combination.
- By mobility method: There are lifting and handling-type mobile toilets, which are usually of a size and weight suitable for movement by lifting equipment or manual handling; and there are also powered and towed-type mobile toilets, which can be moved by means of a power device or a vehicle, offering higher flexibility.
- By sewage treatment method: These include water-flush and waterless-suction mobile toilets. The water-flush type is similar to traditional toilets, using water flow for flushing; the waterless-suction type uses suction equipment to handle fecal sewage; the recirculating water-flush mobile toilet can recycle the flushing water, saving water resources; and the dry-packing mobile toilet packs the feces with biodegradable materials for easy subsequent treatment.
III. Unique Designs Some mobile toilets have unique designs. For example, the economical and practical model has a gray and white exterior, featuring gray and white metal carved panels. It has separate entrances for men's and women's toilets, sliding windows and stone wall lamps on the front wall, and independent squatting positions in the toilet compartments, making it both practical and aesthetically pleasing. In addition, there is the special form of the "tide toilet," which sets up a number of "gender-neutral general toilet compartments" and uses movable signs or lockable sliding doors to dynamically adjust usage rights according to real-time pedestrian traffic, in order to cope with the long queues of women waiting for toilets during peak tourist periods. However, the way its signs are set up may cause controversy. For example, the manually "拨动标识 (flippable signs)" set up at the entrance of the "tide toilets" in Huizhou West Lake Scenic Area in Guangdong have all been removed due to controversy and will be replaced with fixed slot-type door plates.
