Novel public toilet for public toilets

Mobile toilets refer to facilities that can be moved as a whole and set in places or places with fixed or temporary needs to provide toilet services for the public and customers. Mobile toilets originated from people's temporary and staged demand for toilets in some specific occasions, such as construction sites, shipbuilding docks and other workplaces. In order to reduce the time for workers to go back and forth to fixed toilets and improve labor efficiency, mobile toilets were set up on the slipway and construction site. Temporary demand for toilets by large audiences such as large gatherings and sports events, etc. Due to the shortage of the number and layout of urban public toilets, the government has arranged mobile public toilets in areas where it is relatively difficult to build fixed public toilets to make up for the shortage of public toilets and unreasonable layout. The original mobile toilets were made of wood and other materials, with simple structure and function, and easy to absorb odor. Later, it gradually developed to use materials such as FRP and polyethylene. Great changes have taken place in the moving mode of toilets and the treatment mode of fecal sewage, with gradually improved functions and continuously improved service efficiency. Mobile public toilets can be classified according to structure, mobile mode and sewage treatment mode. The specific classification and characteristics are as follows.

1. Classification by structural form

(1) Single-structure portable toilet: A portable toilet is an independent single body with only 1 squatting position inside, which is generally made of materials such as glass fiber reinforced plastic and polyethylene, and can also be spliced with concrete slabs, or covered with light slabs with steel brackets. Its characteristics are light structure, convenient handling or hoisting, and some can even be assembled on site, with small floor space and convenient flexible arrangement. A plurality of mobile toilets with a single structure can also be spliced and connected into a mobile toilet array according to actual needs, so as to meet the needs of a large number of users.

(2) Mobile toilets with combined structure: A single toilet usually has more than two toilet seats, up to 10. Generally, light plates are covered with steel supports, and some containers and bus bodies are modified. It is characterized in that a single toilet contains more squatting positions, which can be used by more people at the same time and has high utilization efficiency.

2. Classification by movement mode

(1) Lift-and-carry mobile toilet: This type of mobile toilet generally has no walking device, and it is completely lifted by the lift device or directly transported manually, or the components are transported to the site for assembly. Portable mobile toilets are generally made of lightweight materials such as FRP and polyethylene, and most of them are single-structure products. Because of its light structure and easy handling and splicing, it is widely used in construction sites, temporary large-scale gatherings, sports events and other places. Among them, mobile toilets used in construction sites are generally regarded as low-value consumables abroad, and are usually scrapped after a project is recycled. Lifting mobile toilets are generally made by covering steel structures with light plates or refitting containers. , can be a single structure, most of which are multi-toilet structures. Because of their great mass, they need to be carried by lifting equipment. Some new lifting mobile toilets are loaded by trolleys, which is more convenient for lifting and moving (see Figure 6). The lifting mobile toilet is characterized by strong flexibility, mechanized handling and high efficiency. Some lifting mobile toilets are also set in relatively fixed places, especially in places where it is impossible to build fixed toilets due to terrain conditions. In case of municipal relocation, it can be upgraded as a whole and reused in other places to reduce the losses caused by demolition.

(2) Electric and trailer-type mobile toilets: Electric and trailer-type mobile toilets refer to vehicle-type toilets with walking devices, which are generally converted from the chassis of large passenger cars and large flat transport vehicles. Among them, the electric mobile toilet has its own power, which can easily travel to places where any vehicle can reach, and it is very mobile. Trailing mobile toilets need to be towed by motor cars and moved to places where they need to be set up. However, because they have no power device, the space utilization rate is relatively high, and it is also possible to decorate them into high-grade mobile toilets. Electric and trailer mobile toilets are characterized by strong mobility, and there are many toilet seats in a single toilet, which is suitable for places with large traffic and high requirements for toilet construction and decoration.

3. Classification according to sewage treatment methods

(1) Flushing mobile toilets and waterless suction mobile toilets: Flushing mobile toilets are equipped with a flushing device. Generally, the water tank is placed on the top of the toilet, and the bottom of the toilet is equipped with a sewage tank, while waterless mobile toilets are not equipped with a flushing device, and the sewage tank at the bottom of the toilet directly receives the user's excrement. Because the sewage tanks of these two types of mobile toilets have small capacity, they need to be pumped in time when the specified number of people use them, otherwise they will overflow easily and the pumping frequency is high.

(2) Circulating water is used to flush the mobile toilet: this mobile toilet is equipped with intermittent aerobic and anaerobic devices to treat fecal sewage and add biological strains. The bio-film technology is used to accelerate the fermentation and decomposition of fecal sewage, and then the treated fecal sewage is reused to wash toilet sanitary ware through the filtering device. It is characterized by adopting advanced fecal sewage treatment technology, saving valuable water resources, reducing the number of fecal sewage pumping and discharging, and fully demonstrating the concept of environmental protection.

(3) Dry-mounted portable toilet: This portable toilet has no flushing device, and the excrement is taken by degradable plastic bags placed under the sanitary ware. Everyone uses it once, and a new plastic bag is automatically replaced. After the plastic bag is used up, it is collected and transported to the treatment plant for disposal. This mobile toilet is characterized by no flushing at all, saving water resources and facilitating the collection of dirt.

4. Automatic toilet

Some mobile toilets have added automation functions, such as automatic door opening after coin-in, automatic flushing of sanitary ware and floor after use, installation of emergency call devices and facilities for the disabled, mobile toilets powered by solar energy, mobile toilets with their own power generation devices and air-conditioning equipment, etc. There are many kinds. For example, at present, there are vacuum toilets, which are automated, rely on solar energy to generate electricity, and rely on rainwater to collect and flush toilets to achieve a high degree of automation. During the long period of tourism development in China, tourist toilets have never been developed accordingly. In some tourist cities, key scenic spots and major tourist routes, the problem of "dirty, chaotic, poor and few" tourist toilets is widespread, which has become a persistent "chronic disease" restricting the development of tourism. Overseas tourists have the most complaints, involving the widest range, and there are also complaints in the market.

Due to the influence of traditional ideas, many places regard tourist toilets as shady places, and avoid this indispensable place for human beings, misinterpreting the site selection principle of building tourist toilets based on "no scenery and no elegance". On the main tourist routes, the layout of toilets is not standardized and scientific, the location is scattered and remote, and the management is difficult, which brings trouble to tourists.

Because the tourist toilets have not been renamed for a long time, and the concept of logo in China is indifferent, almost all public toilets in public places lack obvious graphic symbols of public information, or are ambiguous, or the symbols are reversed by a few pranksters, and there is no standardized bilingual interpretation in Chinese and English, which not only affects the "identifiability", but even leads to the scene of tourists asking about the toilet everywhere outside the toilet, which also threatens the personal safety of tourists.

Due to chaotic management and insufficient funds, the only tourist toilets have been in disrepair for many years, with worn-out appearance and damaged interior. Some roofs are leaking, some interior walls are peeling off, and some toilet doors are damaged. Due to unattended, some toilets have become garbage corners and breeding grounds for mosquitoes and flies. There are many cobwebs hanging in the toilet and many stains on the ground. A few tourist toilets make tourists have no place to stand. Because many dry toilets have obvious odor, there are also a few flush toilets that are not up to standard due to design and management reasons. The sharp contrast between the beautiful feeling of traveling and the dirty scene in the toilet greatly affects the interest of tourists in traveling.
