The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing: it comprises water-closet bowl, the top is provided with toilet seat lid 2, blowoff valve 13 in its rear is provided with rear box 16 and casing, link gear and flushometer, in line water-closet bowl is connected with blowoff valve import 37 on the blowoff valve 13 by the water-closet bowl sewage draining exit 29 of its lower end, valve installing rack 30 is provided with valve 38 directly in the blowoff valve import 37, be provided with the fork linkage in valve 38 rear ends, the blowoff valve of blowoff valve 13 lower ends outlet 36 links to each other with underground blow-off pipe, flushometer is arranged in the rear box 16, it is connected jet water spout 5 by flushing valve 9 with feed pipe 11, the other end of jet water spout 5 and feed pipe 11 is connected with tap water pipe line with water-closet bowl 1 water inlet respectively; Flushing valve 9 is installed on the flushing valve fixed mount 12 by clips 10, the keying of control sewage draining valve 38 and the switch of flushing valve 9 are finished by link gear, when sewage draining valve was in closed condition, interlock frame A bar was angled with the slave pendulum rod that is fixed on the main shaft.

From Fig. 1,3 as can be seen, concrete operations during valve opening: after pin touches foot rest 25, the angle type running-board bracket that can be opposite on the angle type pedal mount pad 24 is exerted pressure, under this effect, angle type pedal A bar 27 makes it up time by pedal rod 23 pulling angle type interlock framves 18 and rotates, because interlock frame A bar 22 links to each other 7 with the flushing valve switch by flushing valve connecting rod 4, in the process that angle type interlock frame 18 clockwise rotates, flushing valve 9 is opened earlier, interlock frame A bar 22 just contacts to go up driven fork 3 and promote its synchronous up time and rotates when angle type interlock frame 18 up times turn over certain angle, because driven fork 3 is affixed with main shaft 17, therefore drive also up time rotation of main shaft 17, and drive blowoff valve inside be fixed on main shaft 17 centre positions fork 34 also synchronously up time rotate, fork 34 pulling valve rods 35 are opened valve 38.

Fig. 2 is the valve closing state diagram, after pin leaves pedal, under the acting in conjunction of follower lever return spring 39 and flushing valve return spring 6, angle type interlock frame 18 rotates counterclockwise, this moment, driven fork 3 pressed interlock frame A bar 22 to rotate counterclockwise by driven becoming initiatively under return spring 39 effects, the fork 34 that is fixed on the main shaft 17 that drives main shaft 17 and blowoff valve 13 inside simultaneously also rotates counterclockwise, the other end of fork 34 is pushing away valve rod 35 makes valve 38 up times rotate, gradually with valve closing.When valve is closed when dead, valve rod 35, fork 34, main shaft 17 and driven fork 3 have all stopped motion; This hour angle type interlock frame 18 continues the inverse time to 7 by flushing valve connecting rod 4 and flushing valve switch and rotates under the effect of flushing valve return spring 6, the frame A bar 22 that meanwhile links is separated from driven fork 3 and also rotates in the inverse time, when flushing valve 9 also is closed, the motion of all members has all stopped, formed the preceding angle of valve opening between interlock frame A bar 22 and the driven fork 3 again, foot rest 25 is also got back to the position before opening; In addition, foot rest 25 can upwards be dug along the axle freedom.In sewage draining valve 38 and flushing valve 9 pent processes, because the effect of friction masthead spring 15, the intermediate disc 40 of friction lever 14 diagonal form interlock all the time frame 18 produces certain pressure, the contact surface of it and friction lever 14 just produces certain frictional force when middle disk 40 rotates with angle of entry type interlock frame 18, frictional force makes the closing motion of sewage draining valve 38 and flushing valve 9 all compare slowly, thereby reaching prevents to wash by water when valve 38 is closed returns to spatter and delays closing of flushing valve 9 after closing with valve 38, makes water-closet bowl sewage draining exit 29 places can store up enough the effect that water plays water seal and is convenient to next blowdown flushing.

The fork linkage is arranged on blowoff valve inside, has improved the sealing performance of valve; Owing to be provided with link gear driving pendulum rod connecting rod control device, it has reduced the strength that pulls blowoff valve to a certain extent, has improved the handling of water closet, has prolonged the application life of component greatly simultaneously; Sealing device has well solved the problem of returning the flavor return of waste water simultaneously.
