Specific embodiment
Fig. 1,2 displays, pedal 1 are mounted on the top surface of box body 16, and sliding block 2 is located at the lower section of pedal 1, and sliding block 2 can be in cunning
It is slided up and down in road 3.4 upper end of mandril is vertical with sliding block 3 to be connect, and 4 lower end of mandril is connected with the top of connecting rod 5 by shaft, even
The centre of bar 5 and ratchet shaft 7 are rotatablely connected, and ratchet shaft 7 is horizontally fixed on the two sidewalls of box body 16.The lower part of connecting rod 5 and fixed
Position 15 upper end of bar is in contact, and the rear end of flow switch 9 is connected with flow valve 10, and flow valve 10 is mounted in pipeline 17.Pawl 8
Front end it is opposite with the ratchet of ratchet 6, the rear portion of pawl 8 is connected with the upper end of connecting rod 5 by shaft, and the upper end of connecting rod 5 also connects
The front end of pawl tension spring 12 is connect, the rear end of pawl tension spring 12 is fixed on the box body 16 of the other side, on the back side disk of ratchet 6
4 annular driving levers 13 vertical with ratchet surface are evenly equipped with, one end of flow switch 9 is connected with flow valve 10, flow switch 9
The other end is located at 6 back side of ratchet and annular driving lever 13 is opposite.Pedal 1 is lifted, pawl tension spring 12 drives the upper end of connecting rod 5 to Forward
Dynamic, pawl 8 moves forward therewith, and pawl 8 pushes ratchet 6 to rotate counterclockwise, and the annular driving lever 13 on ratchet 6 lifts flow switch
9, flow switch 9 is around the annular rotation clockwise of 10 outer ring of flow valve, the rotating ceramic plates 20 and flow of the connection control of flow switch 9
19 drainage hole 22 of fixation potsherd in valve 22 is gradually overlapped, and pipeline 17 is connected to.
Fig. 1, display, 9 middle section of flow switch are connect with the upper end of switch tension spring 11, and switch 11 lower end of tension spring is connected to
On box body 16.Box body 16 is fixed with locating rod 15 below, and when 5 lower end of connecting rod is in contact with locating rod 15, connecting rod 5 stops turning
It is dynamic, while ratchet 6 also stops operating, it is therefore an objective to positioning is all accurate every time, and deviation will not be generated over time.
Fig. 1 shows, circumferential distance and mandril 4 between two adjacent driving levers 13 of 6 back side periphery of ratchet 4 annular driving levers 13
Downward stroke of trampling matches.In this way, an annular driving lever can be driven after leaving pedal 1 every time, when mandril 4 moves up
13 pairs of flow switches 9 lift, and next annular driving lever 13 is moved to the lower section for putting down rear position of flow switch 9, prepare
Flow switch 9 is lifted next time, and so constantly circulation, realization automatically control.
Fig. 3 is shown, solid by metal outer ring 18, fixed potsherd 19, rotating ceramic plates 20, rotating ceramic plates inside flow valve
Fixed rack 21, gasket, sealing ring and gasket composition.Such flow valve belongs to fast open form straight-through valve, due to being using potsherd
Tangential switch water route, very small by influence of hydraulic pressure, the strength of very little can rapid switching valve.Flow switch 9 and metal outer ring
18 are linked together, and the rotation of flow switch 9 drives the rotation of metal outer ring 18, and fluted and rotation is made pottery on the inner ring of metal outer ring 18
Tongue on tile 20 is combined together, and the rotation of metal outer ring 18 drives rotating ceramic plates 20 to rotate, on rotating ceramic plates 20
There are 6 fan-shaped drainage holes 22 of uniform branch, also there are 6 same drainage holes 22 on fixed potsherd 20, with rotating ceramic plates
Drainage hole 22 on 20 interlaces 30 degree, and the size of each drainage hole 22 can be blocked by the physical plane of other side, logical
In normal situation, the contact surface cooperation of rotating ceramic plates 20 and fixed potsherd 19 is close, and circumference outer ring is due to gasket and sealing
The sealing of circle, pipeline 17 are to close, and when rotary current switch 9, will drive the rotation of rotating ceramic plates 20, the fan of two potsherds
Shape drainage hole 22 can be gradually overlapped, and pipeline 17 starts to open, and when rotating through 30 degree, flow switch 9 rotates to final position, and two
Fan-shaped drainage hole 22 on a potsherd is completely coincident, and pipeline 17 is fully open, and the another of flow switch 9 at this time corrects and ring
The outer of shape driving lever 13 is tangent, and continues for some time, until annular driving lever 13 goes to flow switch 9 cannot be tangent again,
Flow switch 9 is switched on and off springs return to original position, while ratchet 6 also stops operating.
There are 4 ratchets on ratchet 6, so the every rotation of ratchet 6 is exactly once 90 degree, where the length of annular driving lever 13 accounts for
2/3rds or so of circle a quarter perimeter, so that the maximum water-flowing amount of flow switch 9 maintains the three of flushing period
/ bis- or so, to guarantee the effect of bath.
Fig. 2 is shown, is connected with rotary damper 14, rotation of the rotary damper 14 to ratchet shaft 7 in the shaft end of ratchet shaft 7
Damping is generated, to make slow its rotation, then water flow flushing has certain time.The damping size for adjusting rotary damper 14 can
To adjust flushing period length.
The section components of one embodiment of the utility model are as follows:
The length of box body is 130mm, is highly 112mm, width 75mm；
The length of connecting rod is 60mm, diameter 5mm；
The diameter of ratchet is 56mm；
The diameter of annular driving lever is 62mm；
Flow valve 10 is the straight-through valve with rapid switch, model JT01；
Rotary damper 14 is disc type bidirectional rotary dampers, model ZB-48A；
The course of work of the utility model is as follows:
When user goes to the toilet, when meeting nature steps on pedal 1, sliding block 2 moves downward in ground way 3, connects with sliding block 2
The mandril 4 connect moves downward.Since mandril 4 is connected with one end of connecting rod 5, the middle part of connecting rod 5 is connected with ratchet shaft 7, institute
It can be rotated clockwise with connecting rod 5 with ratchet shaft 7 for the center of circle, the pawl 8 being connected on connecting rod 5 can be slided along the outer ring of ratchet 6,
Pawl 8 slides down to next ratchet rear portion of ratchet 6, and pawl 8 can be caught in the ratchet of ratchet 6.After user leaves,
The meeting of connecting rod 5 spinning reduction counterclockwise under the pulling force of pawl tension spring 12, while ratchet 6 rotates counterclockwise under the drive of pawl 8.
4 annular driving levers 13 that uniform vertical is fixed on 6 back side disk of ratchet are being moved through as ratchet 6 also does rotation counterclockwise
One of annular driving lever 13 can be in contact with flow switch 9 in journey, and flow switch 9 is lifted up by annular driving lever 13, so that
Flow switch 9 is rotated clockwise around 10 outer ring of flow valve, and pipeline 17 is connected.
After ratchet 6 rotates to certain angle, annular driving lever 13 falls off with the front end of flow switch 9 to be contacted, flow switch 9
It is resetted under the pulling of switch tension spring 11, flow valve 10 is closed, and pipeline 17 ends, so that one of foot-operated mechanical switch uses
Process terminates.It can repeat above step again in next use process, 4 annular driving levers 13 successively stir flow switch 9,
And ratchet 6 can all turn over 90 degree every time, it is unlimited to repeat down.
