Beijing Foaming Mobile Toilet

The Beijing foaming mobile toilet is an environmentally friendly mobile toilet that uses fine foam instead of water for flushing. It features water conservation, intelligence, and strong adaptability, and is widely used in various public scenarios in Beijing.

Technical Principles and Core Components

The foaming mobile toilet generates fine foam by mixing foaming liquid with air through a foaming pump in a mixing chamber. This foam covers the surface of the toilet bowl and wraps around the waste, which is then directed into a waste storage tank. Its core components include a foaming pump, mixing chamber, liquid storage tank, and control circuit. Sensors can automatically detect when a user leaves, triggering the foaming system without the need for manual contact throughout the process. The water consumption per use is only 0.2-0.3 liters, saving over 90% of water compared to traditional toilets.

Technical Features and Adaptability

1. Wide Temperature Range Foaming Technology: In response to Beijing's climate characteristics of high temperature and humidity in summer and dry cold in winter, a variable frequency air pump is used to automatically adjust the air volume based on the ambient temperature, ensuring uniform and fine foam within a temperature range of -15℃ to 45℃. The toilet body adopts a double-layer structure with a polyurethane insulation layer in between to prevent system failures caused by freezing in winter.
2. Air Purification and Intelligent Management: The exhaust vent is equipped with a high-efficiency HEPA filter that can filter pollutants such as PM2.5, preventing outdoor air pollution from entering the indoor environment. The intelligent control module supports remote fault diagnosis and real-time monitoring of equipment status, facilitating centralized management during large-scale events.
3. Ultra-Low Water Consumption Design: Some manufacturers, such as Beijing Anbangjie Technology, offer products that require only about 120 milliliters of water per use, further reducing water costs and making them suitable for areas with water scarcity.

Typical Manufacturers and Products

Beijing Anbangjie Technology Development Co., Ltd. specializes in the research and development of environmentally friendly toilet equipment, independently developing foaming sealing equipment and control systems. Beijing Tianyu Meijie Environmental Protection Technology Co., Ltd. provides integrated services including design, production, sales, and leasing, with products covering foaming ecological environmentally friendly toilets. Beijing Jindongfang Environmental Landscape Engineering Co., Ltd. also offers various types of foaming toilet products.

Application Scenarios and Exterior Design

1. Urban Public Areas: In core urban areas such as the Olympic Park and around Tiananmen Square, the toilets feature gray or beige exteriors that harmonize with the surrounding buildings and incorporate electronic screens to display public service information.
2. Park Scenic Areas: They adopt wood grain or stone texture designs to blend into the natural landscape and reduce visual incongruity.
3. Old Community Renovations: Since they do not require connection to a sewage network, foaming toilets are the preferred temporary sanitation facilities during the renovation of old communities, addressing the challenge of toilet access during construction.
