Wherein the medium is gas or liquid, such as aqueous solution, air, nitrogen, etc.
It should be noted that, in practical use, excrement or urine enters the excrement collecting area 2, and the liquid level does not rise due to the U-shaped sewage discharge pipe 3.
In actual use, the upper end of the piston body 14 can be either open or closed, and a vent hole is required to be left when the piston body is closed.
Wherein, the toilet body is a squatting pan body or a toilet bowl body, namely a squatting pan or a sitting pan.
The toilet bowl flushing process is as follows:
step 1: injecting clear water and oil into the excrement collecting area 2 in the toilet stool to form a water seal 5 and an oil seal 10;
step 2: whether detection sensor detects someone like the lavatory, if detection sensor continuously detects the signal, the duration is: 10-15s, the detection sensor transmits a signal to the controller 18, and the controller 18 enters a standby state;
and step 3: after the detection sensor fails to detect the signal, the detection sensor sends a signal to the controller 18 again; the controller 18 controls the normally open valve 14 to move to a closed state; the driving device 19 drives the piston body 14 to move downwards after receiving a signal transmitted by the controller 18, after a medium enters the elastic bag 11, the liquid level in the excrement collecting area 2 rises, oil used for the oil seal 10 in the excrement collecting area 2 directly flows through the pipeline 23 from the overflow port 20 and then enters the temporary oil seal storage area 21 for temporary storage, after the sensor detects the oil seal 10, the signal is transmitted to the controller 18, the controller 18 controls the first valve 22 to close, and meanwhile, the driving device 19 is controlled to drive the piston body 14 to rise for resetting;
and 4, step 4: after the piston body 14 resets, the volume of the elastic bag 11 resets, the controller 18 controls the action of the normally open valve 14, meanwhile, the flushing device is controlled to flush water in the excrement collecting area 2, sewage is flushed, clean water is supplemented in the excrement collecting area 2, after the flushing device finishes flushing, the time is delayed for 2-3s, the controller 18 controls the first valve 22 to open, the oil seal 10 in the oil seal temporary storage area 21 flows back to the excrement collecting area 2 through the pipeline 23, and flushing of the toilet can be completed.
Therefore, in practical use, compared with the situation that a thin layer of oil seal is arranged each time, the oil seal is flushed together with the oil seal during flushing, the oil seal in the excrement collecting area 2 can be thicker, the plugging effect is better, the odor overflow prevention effect is better, and the waste of the oil seal cannot be caused during flushing.
