The urine of drawing in towards the chamber (132) is discharged fully through breach (148), negative pressure in the air chamber (106) make outside air through breach (148), draw punching (147), cross mouthful (144), a cross-drilled hole (146), enter into communicating pipe (17) in the air chamber (106), negative pressure in the air chamber (106) fades away, back-moving spring (113) resets top pull bar (111), valve head bar (95), top pull bar (111) will lead to closed pore (96) closes, and while valve head bar (95) will lead to closed pore (94) to be opened.

Logical closed pore (94) is opened, make chamber, top (44) via through holes (43), communicating pipe (21), through hole (93) of flushing valve, the passage of logical closed pore (94) be open-circuit condition, chamber, top (44) disappears to the pressure of big plug (47), little plug (51) the big plug (47) that links under the effect of control chamber (86) hydraulic pressure moves upward, and the water in the chamber, top (44) is discharged immediately through the passage of its open circuit.

Little plug (51) moves upward, the space of control chamber (86) is strengthened and the hydraulic pressure reduction, the hydraulic pressure of control chamber (86) reduces, the hydraulic pressure of relative intake antrum (83) is increased, bath dnockout core (55) moves upward under the hydraulic action of intake antrum (83) immediately, rubber cushion (59) will be crossed the mouth of a river (81) and open, from the water inlet of cold water house steward (34), through cold water arm (33), take over (41), come the mouth of a river (39), right load pipe (11), water inlet (82), intake antrum (83), cross the mouth of a river (81), water chamber (70), level pressure mouth (71), delivery port (72), water tank (6), flushing hole (19), (32) urinal is implemented flushing.

Meanwhile, water inlet is also in intake antrum (83), damping slot (57), inflow control chamber (86), water in the control chamber (86) is replenished gradually, and hydraulic pressure increases gradually, and the make progress thrust of impacts flush dnockout core (55) of the hydraulic pressure of relative intake antrum (83) is reduced gradually.

When the upwards thrust of the hydraulic pressure impacts flush dnockout core (55) of intake antrum (83) less than the hydraulic pressure of intake antrum (83) during to the downward thrust of Guan Shuiyan (58), bath dnockout core (55) moves downward together with rubber cushion (59), when rubber cushion (59) moved to position, the mouth of a river (81) gradually, rubber cushion (59) will be crossed the mouth of a river (81) and close, and bath stops.

So far, water-rinsing process is finished in flushing valve (15).

D, anti-secondary draw breaks through journey:

[someone uses, and flushing valve (15) can be drawn be dashed, and the bath of flushing valve (15) self can be drawn self secondary too and dashed.For preventing this from occurring, the utility model has designed anti-secondary and has drawn flushing device, and its process is as follows :]

Cross the mouth of a river (81) bath, the interior hydraulic pressure of water chamber (70) produces, because the elastic force of back-moving spring (67) is less than the elastic force of level pressure water outlet spring (76), right plug tube (68) is before level pressure mouth (71) water outlet, interstage valve head rod (63) will lead to closed pore (62) to be opened, the air chamber of control valve (106) is open-circuit condition through the passage of communicating pipe (16), logical closed pore (62), air inlet (61), (66), urinal bath this moment, the air chamber (106) that is under the open-circuit condition can not produce negative pressure, and secondary draws towards forming.

E, recover to draw and break through journey:

Crossing the mouth of a river (81) bath stops gradually, the hydraulic pressure of water chamber (70) reduces gradually, when hydraulic pressure during less than the pressure of level pressure water outlet spring (76), level pressure water outlet spring (76) promotes left side plug tube (75) level pressure mouth (71) is closed, water in the water chamber (70) is slowly discharged through groove (73), right plug tube (68) interstage valve head rod (63) slowly resets under the effect of back-moving spring (67), and valve head bar (63) will lead to closed pore (62) slowly closes.The air chamber of control valve (106) is closed circuit state through the path of communicating pipe (16), logical closed pore (62), air inlet (61), (66), and control valve (20) restPoses.

The described a of present embodiment, b, c, d, e process are processes continuously and automatically, and need not any operation can realize.

Embodiment 2, manually water-rinsing process:

Press button (120) with hand, button (120) interstage valve head rod (123) will lead to closed pore (117) to be opened, and the water via through holes (54) of control chamber (86), communicating pipe (13), inlet opening (114), logical closed pore (117), drain hole (122) are discharged.

Shuitu in the control chamber (86) is so discharged, the hydraulic pressure of relative intake antrum (83) is increased suddenly, bath dnockout core (55) rubber cushion (59) that link under the hydraulic action of intake antrum (83) moves upward immediately, and the mistake mouth of a river (81) is opened, and flushing valve (15) begins to wash by water.

Connect down process, fully with embodiment 1.
