Description

Technical Field

[0001] This invention relates to the field of public toilet technology, and more specifically, to a prefabricated modular smart public toilet. Background Technology

[0002] Public toilets, also known as public restrooms, refer to toilets used by urban residents and transient populations, such as those attached to government offices, train stations, public spaces, and streets. Public toilets can be classified in various ways based on their architectural style, structure, building grade, spatial characteristics, flushing methods, management methods, or investment channels.

[0003] With urban development, public toilets have not only met residents' needs for restrooms, but have also undergone many attempts in terms of appearance design, intelligent design, and energy conservation and environmental protection. However, the construction of small public toilets on urban streets usually adopts reinforced concrete structures, which have long construction cycles, high manufacturing costs, and limited applicability. For example, in areas where demolition is planned, this structure is unsuitable and easily leads to waste. Furthermore, current public toilet deodorization devices usually use a fan and ductwork, with activated carbon installed inside the ductwork for deodorization. After long-term use, the activated carbon is prone to failure and therefore needs to be replaced. However, existing deodorization ducts are usually fixed to the toilet, making it inconvenient for staff to disassemble and maintain them. Summary of the Invention

[0004] The purpose of this invention is to provide a modular smart public toilet that is easy to install and disassemble, so as to overcome the defects of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated modular smart public toilet, comprising a toilet room, wherein the toilet room is a double-layer structure composed of multiple containers, the upper and lower layers of containers are fixedly connected by a pressure plate, and adjacent containers are fixedly connected by a connecting plate.
