Expandable Outdoor Portable Toilet

An expandable outdoor portable toilet is a facility that can be moved as a whole and is suitable for outdoor scenarios, providing toilet services to the public. The following is an introduction from different aspects:

I. Common Types and Characteristics

• Some expandable outdoor portable toilets have a fixed structural form. For example, the four-squat-position portable toilet launched by Dezhou Hongtu Metal Products Co., Ltd. is 4 meters long and 2.3 meters wide, with a pointed roof. Its exterior wall is made of heat-insulating metal carved panels. The men's toilet is equipped with two squat positions, urinals, and a column basin, and the overall structure can meet outdoor usage requirements. There are also four independent single-room portable toilets that are unisex, with exterior walls made of brick-patterned metal carved panels, also having heat-insulating functions, suitable for high-frequency usage scenarios.
• There are also portable expandable outdoor portable toilets in the form of tents, equipped with folding toilets, curing agents, and garbage bags. This type is suitable for emergency scenarios such as self-driving trips, being convenient to carry and quickly set up for use.

II. Classification by Structure and Moving Method

• By structural form: They can be divided into single-unit structures and composite structures. Single-unit structures are relatively simple and independent, while composite structures may be composed of multiple parts and may have more complex and diverse functions.
• By moving method: They are divided into lifting and handling types and powered towing types. The lifting and handling type requires lifting equipment for movement and placement; the powered towing type can be towed and moved by vehicles, offering relatively high flexibility.

III. Sewage Treatment Methods

• Water-flush type: It uses water to flush the toilet to keep it clean, but it requires connection to a water source and drainage system.
• Waterless suction type: It does not require water for flushing and removes feces and other waste by suction for treatment.
• Recirculating water-flush type: It recycles the flushing water to achieve the goal of water conservation.
• Dry-packing type: It dry-packs feces and other waste for easy subsequent cleaning and transportation.

IV. Design Principles Its design follows the principles of portability, cost-effectiveness, durability, and environmental protection. The overall structure uses lightweight and durable materials to ensure it is not easily damaged during movement. At the same time, it is equipped with complete moving devices for easy setup and movement at different locations.
