When the toilet body is a toilet body, the modular negative pressure toilet does not need a base, and only needs to install and fix equipment such as the toilet body and the rear valve plate box.

There are two ways of flushing the modular negative pressure toilet: induction/manual. Normally, the toilet flushing is mainly started by the sensor, which actively emits infrared rays. After the induction is effective, the toilet controller is activated, and then the toilet controller activates the flush valve and the negative pressure valve in turn to drain the black water (feces and urine) and its flushing water) to the accumulator tank. After the accumulator storage tank receives the sewage, the configured air intake joint supplies the negative pressure to the accumulator when the negative pressure valve of the accumulator is closed. The dirt enters the negative pressure pipeline when it is too "scattered" (very high gas-liquid ratio).

The modular negative pressure toilet flushes the water into the accumulator, which can accommodate 1-4 times of black water entering, and the factory setting of the counter can be 2 times. In this way, when the second toilet flushing is completed, the accumulator controller starts, opens the accumulator negative pressure valve and the vent valve, and discharges the black water in the accumulator storage tank into the negative pressure sewage pipe at an optimized gas-liquid ratio . In special cases, such as cleaning, maintenance, etc., you can manually press the manual button on the sensor to start the toilet sewage. There are two types of wiring for the manual button, one is to start flushing + sewage; the other is to start only sewage. The accumulator is equipped with a manual blowdown button, which is located in the valve plate box. During maintenance, open the front baffle of the valve plate box and press the manual blowdown button to start the blowdown of the accumulator.
