Yanbian Foam-Sealing Mobile Toilet

The Yanbian foam-sealing mobile toilet is a water-saving mobile toilet that uses foam-sealing technology instead of traditional water seals. It features high water-saving rates and a wide range of applicable scenarios, but requires specific installation conditions and regular maintenance.

Technical Principles and Water-Saving Characteristics

The core of foam-sealing technology is to generate a large amount of fine foam through a foaming device, which covers the inner walls of the toilet bowl to form a sealing layer, effectively blocking the diffusion of odors. Compared to traditional water-flush toilets, which consume 3-6 liters of water per use, foam-sealing technology requires only a small amount of water to maintain foam generation (approximately 0.2-0.5 liters per use), achieving a water-saving rate of over 90%. Some models are further optimized as water-saving foam-sealing technologies, which further reduce water consumption by using smart sensors to control the amount of foam generated.

Applicable Scenarios

This type of toilet primarily serves temporary venues with high-frequency use and the need for rapid deployment:

1. Outdoor large-scale events: Such as music festivals, sports events, etc. In scenarios with daily foot traffic exceeding a thousand people, foam-sealing technology can prevent odor issues caused by insufficient water supply in traditional toilets.
2. Temporary gathering points during peak tourist seasons: Areas such as scenic spot entrances and hiking trail rest stops. Its water-saving characteristics reduce reliance on water supply systems in remote areas.
3. Emergency scenarios: When fixed toilets are disabled due to natural disasters or municipal construction, foam-sealing mobile toilets can be quickly put into use.

Installation Requirements

1. Site conditions: A flat, hard surface of at least 4 meters by 3 meters is required to ensure equipment stability.
2. Power supply configuration: If a model with lighting, ventilation, or recirculating water systems is selected, a 220V power outlet must be available on-site; if no power is available, a generator with a recommended power of at least 3kW must be used.
3. Sewage disposal: The discharge path for the waste tank must be planned in advance. Some models support connection to municipal sewage pipes, but compatibility of the interface must be confirmed.

Maintenance Specifications

1. Daily inspections: Every 6 hours, garbage must be cleared, toilet paper replenished, and surfaces disinfected, with a focus on checking the remaining foam liquid level (replenish promptly if below 10%).
2. Technical maintenance: Weekly checks must be performed on the sealing of the sewage valve, the operating status of the water pump, and blockages in the foam generator nozzles, with aging seals replaced as needed.
3. Thorough cleaning: After rental, overall disinfection, high-pressure flushing of the waste tank, and system reset must be carried out, and a maintenance log recorded.
4. Winter protection: Ethanol-based antifreeze (concentration 30%-50%) must be added to the water tank and pipes to prevent freezing and expansion from damaging metal components, while residual water must be drained.

This technology replaces chemical deodorization with physical sealing, offering better environmental performance than traditional blue toilet blocks. However, it requires regular replenishment of dedicated foam liquid (containing surfactants and fragrances), with each bucket costing approximately 200-500 yuan and lasting 1-2 weeks.
