How Do Mobile Toilets in Shanghai Flush?

There are various flushing methods for mobile toilets in Shanghai, with the following being common ones:

High-pressure air-water flushing: This flushing method utilizes the combined action of high-pressure water flow and gas to flush the inner walls of the toilet bowl. Its advantages include high flushing pressure, a wide flushing range, and extremely low water consumption. It only requires one-fifth of the normal water volume to clean the toilet bowl thoroughly. In terms of flushing control, it is jointly accomplished by an infrared sensor and a computer intelligent system. When the sensor detects that someone has finished using and left, the system automatically initiates the flushing program, which is both convenient and intelligent.

Foam flushing: An automatic foam generator is installed in the equipment room, which continuously produces foam, covering the surface of the toilet bowl with a layer of snow-white foam. These foams are generated from a mixed solution. Using foam instead of conventional flushing not only effectively saves water resources but also blocks the emission of odors, keeping the air inside the mobile toilet fresh.

Button-type flushing: Flush buttons can be found inside the mobile toilet. Usually, these buttons are marked with eye-catching text or icons for easy identification by users. A gentle press of the button allows water to flow out for flushing. Some button-type flushing systems are equipped with large and small flush buttons, enabling users to choose different flush volumes according to actual needs, which is more flexible and water-saving.

Sensor-based flushing: It is triggered by infrared or human body sensing technology. When a user brings their hand or part of their body close to the sensing area, water automatically flows out without the need for manual button operation. This makes it more convenient and hygienic to use, avoiding contact between the hands and the flushing device and reducing the possibility of bacterial transmission.

Manual pressing flushing: By manually pressing the device on the water tank, the water inside the tank is quickly squeezed out, and the force of the water is used to flush away the excreta. This flushing method has a relatively simple structure and is more common in some relatively simple mobile toilets.

Foot-pedal flushing: Using the principle of leverage, the user steps on the pedal with their foot, causing the water in the water tank to generate pressure and be discharged, thus achieving the purpose of flushing. This flushing method frees the hands and is more convenient to use in certain specific scenarios.

Electric flushing: An electric water pump is built in. After the power is connected, the water pump starts working to increase the water pressure. Pressing the electric flushing button completes the flushing. Electric flushing can provide stable and strong flushing pressure to ensure the flushing effect.

Gravity flushing: The water tank is installed at a relatively high position. Relying on the gravity of the water itself to generate flushing force, when the drain valve of the water tank is opened, the water naturally flows out for flushing.

Foot-pedal black ball flushing: It is relatively common in simple mobile toilets. After using the toilet, stepping on the black ball will automatically flush the squatting pan, which is simple and convenient to operate.
