Mobile Toilet Anti-Splash Foam
The primary method for achieving anti-splash effects in mobile toilets is the use of anti-splash foam, with its principles and application scenarios as follows:
Core Mechanism of Anti-Splash Foam
Anti-splash foam forms a dense foam layer at the interface between excreta and water or air, utilizing the physical properties of foam to achieve multiple functions. The surface tension of the foam effectively prevents excreta from splashing, reducing the range of liquid splatter. At the same time, the foam layer covers the surface of the excreta, suppressing odor diffusion and reducing the adhesion of dirt through lubrication, achieving a self-cleaning effect. For example, the foam sealing layer technology used in "Fragrant Toilets" reduces the need for flushing through continuous foam coverage while isolating odors, making it suitable for public mobile toilet scenarios.
Typical Application Cases in Mobile Toilets
"Fragrant Toilets" are eco-friendly mobile toilets developed by Nanjing Xieli Environmental Protection Technology Co., Ltd., with their core innovation being foam sealing layer technology. This technology generates a large number of tiny bubbles through a foaming device, covering the inner walls of the toilet bowl and the surface of the excreta to form a physical barrier. The foam layer can reduce water consumption by more than 90%, while also lowering the risk of bacterial transmission, making it suitable for high-traffic scenarios such as tourist attractions and temporary events. Additionally, the lubricity of the foam makes it easier for waste to be discharged, reducing pipe blockages.
Technological Extensions in Smart Toilet Products
Some household smart toilet products have also adopted anti-splash foam technology, such as models JOMOO 690P, Monarch Sanitary Ware M40, Huida X08, and JOMOO Family Bucket Air ZS760J, all equipped with a "foam shield" function. These products automatically release foam to cover the water surface before the user uses the toilet through built-in foaming devices, forming a buffer layer. The foam shield not only prevents splashing but also achieves deodorization and sterilization by adding fragrances or disinfectants, enhancing the user experience. Its application scenarios are more focused on households or high-end public places, emphasizing comfort and hygiene.
Technological Advantages and Limitations
The advantages of anti-splash foam technology lie in its low cost, high efficiency, and environmental friendliness. The foam layer reduces water consumption and sewage discharge, aligning with green environmental trends. However, its limitations include the need for regular replenishment of foaming liquid and the potential decrease in foam stability under extreme low-temperature conditions. Additionally, in mobile toilet scenarios, the maintenance convenience of the foam generation device needs to be considered to avoid affecting usage due to equipment failures.
