How to Flush a Mobile Toilet

There are three main flushing methods for mobile toilets: high-pressure air-water flushing, foam flushing, and storage-type flushing. The specific operations and principles are as follows:

1. High-pressure air-water flushing
This method completes flushing through the synergistic action of high-pressure water flow and gas. Its core components include a high-pressure water pump, a gas storage tank, and an intelligent control system. During flushing, the system injects compressed air into the water flow, forming a high-pressure mixed fluid that is sprayed at high speed onto the inner wall of the toilet bowl, using the impact force to remove waste. This method uses only one-fifth of the water compared to traditional flushing, but it relies on electricity to drive the water pump and air pump. The flushing control is achieved through the联动 (coordinated action) of an infrared sensor and a computer intelligent system: when the user leaves, the infrared sensor detects the signal and triggers the computer program to initiate high-pressure flushing, ensuring precise control over the duration and pressure of each flush to avoid water waste.

2. Foam flushing
This technology generates a large amount of fine foam through an automatic foaming device to cover the surface of the toilet bowl. The foaming machine mixes a foaming agent with water in a specific ratio and blows it with compressed air to form a dense foam layer. The foam has three main functions: Firstly, it reduces waste adhesion through lubrication, making flushing easier; Secondly, the active ingredients in the foam can decompose organic matter, aiding in cleaning; Thirdly, the foam layer forms a physical barrier that effectively blocks odor emission. Since the foam itself has cleaning capabilities, this method does not require traditional flushing and only requires periodic replenishment of the foaming liquid, resulting in extremely low water consumption. Some high-end models are also equipped with a foam thickness monitoring system that automatically adjusts the foaming amount to maintain optimal coverage.

3. Storage-type flushing
This method is suitable for scenarios without access to water and electricity, and its flushing mechanism relies on manual water injection. The toilet has an independent water storage tank inside, and users need to manually add clean water through a water injection port next to the sink. During flushing, the mechanical valve inside the water storage tank is pulled or the flush button is pressed, allowing the stored water to flow into the toilet bowl by gravity to complete the flushing. Such toilets are usually equipped with a large-capacity water storage tank (generally 100-200L) that can meet the needs of dozens of flushes but require regular manual water replenishment. Some models adopt a dual-tank design, separating the water for flushing the toilet from the water for handwashing, enabling secondary utilization of water resources and further improving water-saving efficiency.
