Working principle:
in the automatic mode, the pre-flush function is not enabled; after a user sits on the seat cushion 4, the air bag 45 is compressed, the movable magnetic piece 44 moves downwards to be close to the fixed magnetic piece 522, the fixed magnetic piece 522 presses the bag body 521 to deform, the water pressure in the water bag 52 rises, the elastic arc piece which originally seals the pre-outlet is deformed after being subjected to the water pressure exceeding the deformation threshold value to open the pre-outlet, at least part of water flows into the sealing cavity, the pressure for driving the sealing slide block 510 to move downwards is greater than the water pressure of the water flowing into the sealing cavity at the moment, so that the sealing slide block 510 cannot move downwards, and the main outlet is sealed and cannot be discharged; the main flushing is started until the user finishes discharging, as the deformation of the elastic arc piece is acquired by the piezoelectric ceramic, the controller inputs a signal for deformation of the elastic arc piece, the controller controls the main water pump to pump out water with smaller consumption than the normal flushing, the water enters the main waterway and then enters the branch water pipe 56, the water pressure in the branch water pipe 56 rises to press the elastic arc piece to deform, and the water pressure is far higher than the water pressure during pre-flushing when the main flushing is performed, so that the deformation amount of the elastic arc piece is larger and the deformation retention time is longer at the moment, so that more water in the water bag 52 is discharged into the closed cavity, the water pressure in the closed cavity is larger until the pressure exceeds the pressure threshold for driving the sealing slide block 510 to move downwards, the sealing slide block 510 moves downwards to open the main outlet, and the partial water in the closed cavity is discharged to assist the flushing of the pit of the toilet 1; it should be noted that, the return of the sealing slider 510 is slow, so that the water in the closed cavity can be completely discharged, and the automatic mode of the next use is not affected, and the slow return can be realized by setting the return object to be an elastic sponge or setting the return object to be a rectangular sealing ring, etc., which are conventional usage means for those skilled in the art, and are not described herein.
In manual mode, enabling a pre-flush function; before a user sits on the cushion 4, the upper cushion 41 is lifted and then pressed down, so that the air bag 45 is exhausted, and the air outlet pipe 58 fills the air exhausted by the air bag 45 into the closed cavity; the air pressure generated by the single air charge is equal to the pressure threshold value for driving the sealing slide block 510 to move downwards, so that the main outlet is in a critical state to be opened; at this time, the user sits on the seat cushion 4, part of water in the water bag 52 is discharged into the closed cavity, the pressure in the closed cavity exceeds the pressure threshold for driving the sealing sliding block 510 to move downwards, the main outlet is opened, the water is discharged to realize pre-flushing, the pre-flushing water quantity is smaller than the normal pre-flushing water quantity for saving water, if the normal pre-flushing water quantity is achieved, the water quantity in the water bag 52 can be set to exceed the single pre-flushing water quantity, so that the water quantity discharged by deformation of the elastic arc piece due to sitting action is equal to the normal pre-flushing water quantity, which is a conventional use means of a person skilled in the art and is not repeated here; meanwhile, the main outlet discharges high-pressure gas in the closed cavity while discharging water, so that the next use is not influenced, and water in the closed cavity is positioned at the lower side of air, so that the main outlet discharges water first and then discharges air, and the quick reaction of the pre-flushing function is not influenced.
Specific embodiment II: referring to fig. 8, unlike the first embodiment, the branch water pipe 56 has two water outlets, one of which is provided as in the first embodiment. The other outlet extends through the outlet tank 59 and communicates with the enclosed chamber so that part of the water in the enclosed chamber is discharged through the main outlet at the same time as the main flush.
The advantage of this kind of setting lies in, because elastic arc piece 54 is the elastic component, can reduce deformation sensitivity after long-term use, appears the asynchronous problem of deformation of two elastic arc pieces, and the partial water that mainly washes water at this moment directly fills in the closed chamber, and with the closed chamber impact open, be convenient for discharge the residual water of closed intracavity, be convenient for use next time.
Third embodiment: referring to fig. 9, unlike the first embodiment, in this embodiment, the elastic arc member 54 has only one elastic arc piece to close the pre-outlet; the upper end of the elastic arc piece is abutted with a magnetic conduction piece 512;
in this embodiment, the control system further includes an electromagnet 513; electromagnet 513 is controlled by the controller to be powered on and off; the electromagnet 513 is positioned in the equipment cavity 21 and is positioned on the upper side of the transition box 53 corresponding to the elastic arc piece 54; because the upper wall of the water outlet chamber can stretch to a certain extent, the electromagnet 513 is electrified to attract the magnetic conductive sheet 512 to move upwards so as to release the deformation space of the elastic arc sheet, namely the elastic arc sheet tends to keep straight; the lower end of the elastic arc piece is abutted with the piezoelectric ceramic 55, and the connection relation of the piezoelectric ceramic 55 in the control system is consistent with that in the first embodiment;
only one water outlet end of the branch water pipe 56 penetrates through the water outlet tank 59 to be communicated with the closed cavity;
when a human body sits on the seat cushion 4, the internal pressure of the water bag 52 is increased, the pressure variation received by the elastic arc piece is increased, the pressure variation is sensed by the control system, the controller controls the electromagnet 513 to be electrified, the magnetic conduction piece 512 is attracted to move upwards, the pre-outlet is promoted to open water, the water bag 52 can discharge water into the closed cavity, and the closed cavity can not be opened at the moment; when the main flushing water is supplied, part of the water of the main flushing water is introduced into the closed cavity, and part of the water which is discharged along with the water bag 52 is discharged from the main outlet;
this arrangement has the advantage that in the manual mode the amount of water discharged by the pre-flush can be increased.
