In order to realize drainage of the water tank with different volumes, at least one inflation tube 32 is provided, and the quantity of the inflator pump(s) 81 is the same as the quantity of the inflation tube(s) 32. Inflation volumes of the inflator pumps 81 are different. More particularly, the inflator pump 81 comprises a first inflator pump 81a and a second inflator pump 81b. An exhaust volume output by the first inflator pump 81a in a preset time duration is larger than an exhaust volume output by the second inflator pump 81b. The inflation tube 32 correspondingly comprises a high-volume flushing tube 32a and a low-volume flushing tube 32b. An opening time duration of the pneumatic drainage valve 31 is t1 when the pneumatic drainage valve 31 is triggered by the high-volume flushing tube 32a, and the opening time duration of the pneumatic drainage valve 31 is t2 when the pneumatic drainage valve 31 is triggered by the low-volume flushing button 32b. Here, t1 is greater than t2.
The control module controls a first inflator pump 81a or a second inflator pump 81b to start according to a detection situation of the human body sensor 62. Specifically, when the human body sensor 62 is an infrared sensor, a microwave sensor, or an ultrasound sensor, the first inflator pump 81a or the second inflator pump 81b is controlled to start by sensing time durations when infrared rays, microwaves, or ultrasonic waves emitted by the infrared sensor, the microwave sensor, or the ultrasonic sensor are blocked. For example, when the blocked time duration T is greater than the first preset time duration T1, the first inflator pump 81a is controlled to start. When the blocked time duration T is greater than the second preset time duration T2, but less than the first preset time duration T1, the second inflator pump 81b is controlled to start. Here, T1 is greater than T2. When the human body sensor 62 is a remote control sensor, the remote control sensor includes two capacitive sensors arranged on the third panel body 61 at intervals. When the user blocks the first capacitive sensor with hand, the first inflator pump 81a is controlled to start. When the user blocks the second capacitive sensor with hand, the second inflator pump 81b is controlled to start.
As shown in
During working, when the human body sensor 62 on the third panel body 61 senses a human body, the control module controls the first inflator pump 81a or the second inflator pump 81b to start according to the detection situation of the human body sensor 62. The generated air pressure is filled into the pneumatic drainage valve 31 through the high-volume flushing tube 32a or the low-volume flushing tube 32b. Thus, the valve for high-volume flushing or low-volume flushing may be opened, and a ceramic flush toilet can be cleaned by the water tank.
