The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
Consult Fig. 2, the preferred embodiment that the utlity model has the Water flushing for cistern device of hydraulic actuation valve group 2 comprises electromagnetic valve 4, a water-supply-pipe 5, a hydraulic actuation valve group 2, a moving part 6 that flows in order to control liquid, and one with the water discharging valve 7 of hydraulic actuation valve group 2 by moving part 6 connections.Water-supply-pipe 5 comprises that a connection to the water inlet pipe portion 51 of electromagnetic valve 4 and branches out and be connected to the control valve portion 52 of hydraulic actuation valve group 2 from water inlet pipe portion 51.In the present embodiment, moving part 6 is a rope.
Consult Fig. 3, Fig. 4 and Fig. 5, hydraulic actuation valve group 2 comprises a hydraulic cylinder 3, a rocking bar 21, a piston rod 22, an elastic parts 23 and an installed part 24.
Following leg 35 is formed with most side direction leakage openings 351.Last leg 34 has an end and is butted on down the annular basal wall portion 341 of the end face of leg 35, and respectively from basal wall portion 341 inner peripherals and outer peripheral edges a leg portion 342 and a peripheral wall portion 343 in one of extension downwards at intervals.Last leg 34 also has from the bottom of peripheral wall portion 343 downwards and stretches out, is positioned at described leakage opening 351 outsides of leg 35 down, and the ring-type guide lug portion 344 of the downward liquid flow that flowed out by described leakage opening 351 of guiding.
The inboard of peripheral wall portion 343 reaches down, and the outside of leg 35 is formed with most individual cooperatively interacting with the mobile grab 346,353 of restriction above-below direction respectively.Grab 346 enter angle θ
1(consulting Fig. 7) is less and withdraw from angle θ
2(consulting Fig. 7) is bigger, makes down leg 35 be sticked in the peripheral wall portion 343 of leg 34 easily, but is difficult for getting loose after the engaging, makes hydraulic cylinder 3 can bear the impact of high hydraulic pressure.
Because the outer peripheral face of leg 35 was all the design of circular arc under the inner peripheral surface of peripheral wall portion 343 reached, so when last leg 34 was sticked in down leg 35, last leg 34 can be adjusted the angle of the two with respect to leg 35 rotations down.
In addition, the interior leg portion 342 of last leg 34 in contrast to a side face of peripheral wall portion 343 be formed with most extend and be resisted against piston rod 22 up and down lead rib 345.Owing to lead the design of rib 345, reduce piston rod about in the of 22 during slippage and the contact area of interior leg portion 342, and then reduce frictional resistance.
In the present embodiment, upper and lower leg the 34, the 35th, separable, but upper and lower leg 34,35 also can be one-body molded.
Piston rod 22 is positioned at the body 32 of hydraulic cylinder 3, and is the cylindrical hollow housing of an opening towards input part 31.Piston rod 22 comprises that one wears and part convexedly stretches in the end face of leg 34 and is resisted against the rod body 221 of the middle body of rocking bar 21, reaches a shoulder 222 that is connected in rod body 221 belows, and the radius of shoulder 222 is greater than the radius of rod body 221.The described rib 345 of leading of the interior leg portion 342 of the outer peripheral face of rod body 221 and last leg 34 contacts.
Because piston rod 22 is opening hollow housings towards input part 31, so shoulder 222 do not need closely to contact with the internal face 354 of hydraulic cylinder 3 and can produce enough upwards thrust yet, thereby can reduce the wearing and tearing of internal face 354.In addition, the top of rod body 221 is curved, is successional sliding-contact when making piston rod 22 promote rocking bar 21, the phenomenon that does not have shake or have some setbacks.
Piston rod 22 is by the liquid start that flows into input part 31, and can be mobile between as shown in Figure 5 primary importance and a second place as shown in Figure 6 with respect to input part 31.
Installed part 24 comprises that department of assembly 241, that a cross section roughly is the C type is fit to be installed on the connecting portion 242 of a vertical rod 8, and two separate rib 243.Connecting portion 242 is arranged in a vertical rod 8, and is lock onto in the vertical rod 8 by a bolt group.Department of assembly 241 is arranged in the following leg 35 of body 32.The described rib 243 that separates is separated department of assembly 241 with connecting portion 242, the elasticity of its clamping can not interacted.
Following leg 35 is formed with two ring-types that are resisted against department of assembly's two opposing faces about in the of 241 respectively and keeps off edge 352.Described retaining edge 352 restriction hydraulic cylinders 3 are with respect to the slip of the above-below direction of installed part 24.Cooperate the inner peripheral surface of department of assembly 241 and down the outer peripheral face of leg 35 be all the design of circular arc, so when leg 35 was sticked in department of assembly 241 instantly, hydraulic cylinder 3 can be adjusted the angle of the two with respect to installed part 24 rotations.
Consult Fig. 2, Fig. 5 and Fig. 6, when the user does not use, the full liquid of storage in the water tank, because electromagnetic valve 4 is for cutting out, thereby the input part 31 of no liquid inflow hydraulic cylinder 3.At this moment, piston rod 22 is positioned at primary importance, and its shoulder 222 touches in input part 31.Rocking bar 21 is not subjected to upwards replacing of piston rod 22, thereby is switched to minimum angle.At this moment, rocking bar 21 does not spur moving part 6, and water discharging valve 7 is a closed condition.
After the user used, sensor (figure does not show) was sensed the user and is finished using, and opens solenoid valve 4 makes liquid flow into water-supply-pipe 5, and liquid flows into water inlet pipe portion 51, control valve portion 52 in regular turn, flows into the input part 31 of hydraulic cylinder 3 again.The hydraulic drive piston rod 22 that liquid caused is moved upward to this second place by this primary importance, the rod body 221 top contact rocking bars 21 of piston rod 22 upwards pivot, moving part 6 by an end 212 that is connected in rocking bar 21 draws back water discharging valve 7, makes the wash water that is stored in the water tank can flow out water tank.In the present embodiment, described leakage opening 351 is positioned at the below when the shoulder 222 of piston rod 22 during in this second place.When hydraulic pressure was big, the bottom that the shoulder 222 of piston rod 22 is resisted against the interior leg portion 342 of leg 34 no longer made progress, and this moment, highly pressurised liquid can outwards be flowed out by described leakage opening 351, and the liquid of outflow and guided by guide lug portion 344 flows downward.This designs the speed that moves up that can slow down piston rod, and two can avoid the get loose engaging of upper and lower leg 34,35 of high pressure.
After wash water was flowed out by water discharging valve 7, electromagnetic valve 4 reverts to closed, thereby no liquid flows into the input part 31 of hydraulic cylinder 3 again.At this moment, piston rod 22 is subjected to the elastic-restoring force of elastic parts 23 to return back to this primary importance, and no longer contact rocking bar 21 upwards makes rocking bar 21 be switched to minimum angle.At this moment, water discharging valve 7 is closed again, makes the refilling of water tank energy, waits for use next time.
In sum, be articulated in the design of the support portion 33 of hydraulic cylinder 3, so do not need to adjust when mounted the relative position of rocking bar 21 and hydraulic cylinder 3 by rocking bar 21.And because piston rod 22 is opening hollow housings towards input part 31, therefore the shoulder 222 of piston rod 22 does not need can produce enough upwards thrust with internal face 354 tight contacts of hydraulic cylinder 3 yet, thereby can reduce the wearing and tearing of internal face 354, so can reach effect of the present utility model really.
