How to Flush Beijing Mobile Toilets
The flushing methods of mobile toilets in Beijing vary depending on the type, mainly divided into two types: water-flushing mobile toilets and simple mobile toilets, as detailed below:
Water-flushing mobile toilets have relatively common and diverse flushing methods. One is the conventional water tank flushing method. These toilets are usually equipped with a small water tank to store cleaning water. The water tank is generally installed in a conspicuous and easily operable position inside the toilet. When the user finishes using the toilet, they simply press the flush button located near the toilet bowl or on the water tank, and the water in the tank will quickly flush the toilet bowl through pre-designed pipes. The water flow will carry the waste in the toilet bowl into a specially designed collection container below, which usually has good sealing properties to prevent odor emission and waste leakage.
The other is the negative pressure air-flushing technology, which is adopted by some water-flushing mobile toilets as a more advanced method. A small vacuum pump is installed inside the toilet. When the user presses the flush button, the vacuum pump starts immediately, generating a negative pressure of about 0.6 to 0.8 atmospheres in the pipes. Under the action of the negative pressure, feces and a small amount of flushing liquid are quickly sucked into the storage tank at a speed of about 3 to 5 meters per second. This flushing method not only has a strong flushing force, effectively cleaning the waste, but also uses relatively less water, making it more water-saving and environmentally friendly. At the same time, due to the action of the negative pressure, it can also reduce odor emission to a certain extent and keep the air inside the toilet fresh.
The flushing method of simple mobile toilets is relatively simple. After the user finishes using the toilet, they simply step on the black ball located near the squat hole, and the squat hole will automatically flush. This design is usually achieved through a mechanical linkage device. When the black ball is stepped on, it triggers the internal water flow control mechanism, causing the stored water to flow out and flush the squat hole, carrying away the waste. The flushing method of simple mobile toilets is easy to operate and is suitable for use in places with relatively low facility requirements and low usage frequency.
