How to Flush Mobile Toilets in Japan

There are mainly two types of flushing methods for mobile toilets in Japan: high-pressure air-water flushing and foam flushing, with specific operations and principles as follows:

High-pressure air-water flushing is one of the common flushing methods for mobile toilets in Japan. Its core principle is to use the mixed action of high-pressure water flow and gas to flush the inner wall of the toilet. In actual use, after the user finishes excretion, there is no need to manually operate the flush button. The flushing process is jointly controlled by an infrared sensor and a computer intelligent system. The infrared sensor can accurately sense the presence and departure status of the user. When it senses that the user has left, it will send a signal to the computer intelligent system. After receiving the signal, the computer intelligent system quickly starts the high-pressure air-water flushing device, simultaneously spraying high-pressure water flow and gas onto the inner wall of the toilet. The powerful impact can quickly and effectively flush away the dirt, ensuring the cleanliness of the toilet. This flushing method not only has a strong flushing force and good cleaning effect but also saves water because the mixed use of high-pressure air and water can achieve a good flushing effect with less water.

Foam flushing is another unique flushing method. It covers the surface of the toilet bowl with a layer of snow-white foam through an automatic foaming machine. These foams are produced by a special mixture. The foam has a lubricating and isolating effect. When the user excretes, the dirt will directly fall into the foam and will not directly contact the inner wall of the toilet bowl, thus reducing the adhesion of the dirt to the toilet bowl. At the same time, the mixture in the foam has certain cleaning and disinfecting functions, which can inhibit the generation of odors. During use, the automatic foaming machine continuously produces foam to maintain the thickness of the foam layer on the surface of the toilet bowl. When cleaning is required, a small amount of water can flush away the foam and dirt together. This flushing method not only saves water but also effectively reduces odors, providing users with a more comfortable and hygienic toilet environment.
