Back pressure cavity 112, discharges in 141 and from first, second relief hole 113,142.Due to now, described first back pressure cavity 112 and institute
State the second back pressure cavity 141 and be in relatively low pressure state, therefore, the piston 174 in time delaying hydraulic cylinder 172 is at piston reset elastic component
During the effect of 175 lower extrolling, the water in chamber 171 makes it slowly flow out into the first back pressure cavity 112 from time delay spilled water hole 173
In, owing to time delay spilled water hole 173 is less, therefore sluicing speed is slow, causes piston 174 movable slowly, and then makes and piston 174
The sealing part 178 of linkage is slowly near the 3rd relief hole 143, until sealing part 178 seals the 3rd relief hole 143, due to second
Water in back pressure cavity 141 cannot continue to release, and causes the back-pressure of the second back pressure cavity 141 to increase (the second back pressure cavity now
Intake pressure in the back-pressure of 141 and the second intake tunnel 140 is equal) so that the second back pressure diaphragm 145 moves down close
Seal the second exhalant canal 150, thus achieve the delay-self-closing of the second exhalant canal 150.
As shown in Fig. 9 and Fig. 1, under T1-T2 state in fig. 2, described main bath road 160 keeps delay-self-closing state,
That is, described second intake tunnel 140 remains off, and described second back pressure cavity 141 is in described relatively high pressure state, institute
Stating main bath road 160 and continue actively to aspirate the water in water tank under the rainbow suction of siphoning installation 153, described first water inlet is logical
Road 110 remains open to described clean water route 130 and is held open state, and described first back pressure cavity 112 is in relatively low
Pressure condition, owing to the elastic force of piston reset elastic component 175 can overcome the back-pressure of the first back pressure cavity 112 now so that lives
Plug 174 drives sealing part 178 to keep closing with described 3rd relief hole 143 under the active force of described piston reset elastic component 175
Closed state so that the second exhalant canal 150 remains off；
