Specific embodiment
The present invention is specifically described with reference to the accompanying drawing, as shown in Figure 1, in the present embodiment, when people enters lavatory,
Human body proximity sensor 21 detects human body and approaches, and Timer module detection people enters the lavatory time, without rushing manually after people has facilitated
Water can directly leave away, and human body proximity sensor 21 detects that people is separate and will send information to controller 10,10 basis of controller
People enters lavatory temporal information and judges that people defecates or urine；
If entering the lavatory time reaches preset value, controller 10 is judged as that stool flushing, controller 10 control servo-electric push rod 13 and stretch
Contracting end is contracted to minimum value, and servo-electric push rod 13 drives scissors crotch 12 to move, and scissors crotch 12 folds after-contraction, scissors fork
12 upper end of frame is fixed on motionless on case lid 2,12 lower end of the scissors crotch drive rising of water squeezing plate 11, its underpart after water squeezing plate 11 rises
Pumping chamber 5 form negative pressure, the water storage in water storage room 7 is in self gravity and pumping chamber 5 by pressurized water tubes 16 under suction function
Into pumping chamber 5, the first check valve 18 partition pressurized water tubes 16 lead to the access of pumping chamber 5, make pressurized water tubes 16 have by
The one-way passage that pumping chamber 5 is discharged outward, therefore cabinet external fluid can not enter pumping chamber 5 by pressurized water tubes 16, work as water squeezing plate
After 11 rise to highest point, full water is stored in the pumping chamber 5 of 11 lower section of water squeezing plate, subsequent 13 telescopic end of servo-electric push rod is stretched
Out, water squeezing plate 11 declines, and second one-way valve 19 separates the access that drinking-water pipe 17 is led to water storage room 7 by pumping chamber 5, makes drinking-water pipe 17
Only lead to the one-way passage of pumping chamber 5 with water storage room 7, therefore water will not be flowed into water storage room 7, pressure by drinking-water pipe 17 in pumping chamber 5
Pressure (hydraulic) water flows to closestool by pressurized water tubes 16 in water chamber 5, so that excreta be washed down；
If entering the lavatory time is not up to preset value, controller 10 is judged as that urine flushing, controller 10 control servo-electric push rod 13
Telescopic end is shunk, and the contracted length of 13 telescopic end of servo-electric push rod is less than its minimum value at this time, by distinguishing stool and urine, thus
For stool and urine difference and select different amount of flush water, reach water-saving result；
In water storage room 7 after discharge reduction, the floating ball of ball-cock assembly 9 declines, and ball-cock assembly 9 opens the access of water supply pipe 8 and water storage room 7,
Water supply pipe 8 is to 7 moisturizing of water storage room, and when floating ball rises to certain altitude, ball-cock assembly 9 is closed, and completes 7 moisturizing operation of water storage room.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
