See also Fig. 1, the urinal flusher that the utility model proposes has enclosed tank body 1, is contained in water volume control device 3 and flushing valve 4 in the tank body 1, and the manual water-supply valve 2 that is contained in tank body 1 outside appropriate location.Described water-supply valve 2 is by the water inlet on it 21 and delivery port 22 and be connected with feed pipe (not illustrating) and flushing valve 4 respectively.Ask for an interview Fig. 2, movable rod 26 movably is housed on the valve body of water-supply valve 2, the outer end of valve body that is positioned at of movable rod 26 is equipped with button 23, an end that is positioned at valve body of movable rod 26 has flange 211, body cavity is divided into epicoele 212 that communicates with delivery port 22 and the cavity of resorption 213 that communicates with water inlet by next door 214, and epicoele 212 and cavity of resorption 213 are that current communicate, on the described next door 214 movable valve stem 216 is housed movably, the lower end of this movable valve stem 216 has movable valve 25, the path of this valve seat can be opened or close to valve seat 24 synergy at movable valve 25 and cavity of resorption 213 places, and described movable rod 216 upper ends are set with to be closed spring 29 and have dish 27, this dish 27 in epicoele 212 and and the inside wall of epicoele 212 between have suitable gap 215.

When non-flushing, water-supply valve 2 is in normally off, when pressing button 23 makes flange 211 against dish 27 and overcome the reaction force of closing spring 29 and pressure that water supply acts on movable valve 25 moves down dish 27 and movable valve 25 is lifted off a seat 24 the time, the press water of feed pipe is by water inlet 21, the through hole of valve seat 24, cavity of resorption 213 flow to the top of the dish 27 in the epicoele 212, flow to the bottom of the dish 27 in the epicoele 212 through the gap 215 between dish 27 and epicoele 212 inside walls continuously then, again in delivery port 22 flows to flushing valve 4 in the tank body 1 continuously.Because water is constantly to flow, so when the water on 27 tops of the dish in the epicoele 212 flows through gap 215, because the throttling action in gap, partial pressure in the circulating water can be depleted, so the pressure of dish 27 tops in the epicoele 212 is greater than the pressure of dish 27 belows, because this pressure differential, forces and close spring 29 and be in confined state, so movable valve 25 keeps the state that leaves with valve seat 24, circulating water unhinderedly continuous stream in flushing valve 4.In case water filling arrives pre-provisioning request in the tank body 1, for example, the water yield in the tank body 1 is near reaching scheduled volume, float come-up makes delivery port partly close discharge when diminishing, perhaps, lower by pressure in feed pipe, when not reaching predetermined amount of water as yet, tank body internal pressure and feed pipe internal pressure tend to be balanced and discharge are reduced, when discharge reduces, also reduce by the water in gap 215 is mobile, the throttling losses of flowing by gap 215 also reduce, and are tending towards equal so coil the water pressure of 27 above and belows, at this moment, on the effect lower wall 27 of the elastic force of closing spring 29, move, movable valve 25 and valve seat 24 against, water inlet is flowed and then is cut off.That is to say that in case movable valve 25 is touched unlatching, pass through as long as there is enough water to flow, movable valve 25 just is held open state, reduces to predetermined extent in case water flows, close automatically and cut off circulating water and no longer feed water closing under spring 29 effects movable 25.

Ask for an interview Fig. 3 and Fig. 4, flushing valve 4 has by flushing valve upper body 412 and flushing valve lower body 413 usefulness screws and combines and the valve body that constitutes, 413 one-tenth cup-shapeds of this lower body and having towards by towards the floss hole 410 of urinal, water one-way valve 46 is equipped with out at outlet 49 places of these upper body 412 upsides, then adorn on the worn-out mouth of the downside of upper body 412 and be stamped movable film 43, the valve plug 44 that has micro through hole 42 is housed on this film 43, the periphery of valve plug 44 lower surfaces and floss hole 410 leaves then open floss hole 410 against then closing floss hole 410.Upper body 412 is contained on the tank body 1, and the discharge-channel 411 on 412 sidepieces of upper body is linked up tank body 1 inner discharge chamber 414 with film 43 downsides.Water volume control device 3 is equipped with in the outside at the one way valve above the upper body 412 46 on upper body 412, this water volume control device 3 has spiral shell and is contained in goblet 35 on the upper body 412, has delivery port 33 on the cup-shaped spare 35, slide bar 34 movably is contained on the cup-shaped spare 35, the lower end of slide bar 34 has the valve disc 32 with outlet 33 mating reactions, has float 31 in its upper end.

When the circulating water from water-supply valve 2 entered pressure chamber 41 through the inlet on the upper body 412 48, one way valve 46 was backed down, circulating water enters in the cup-shaped spare 35 and by delivery port 33 and enters in the tank body 1.Certainly, at this moment also there is the micro through hole 42 the valve plug 44 of water from film 43 of minute quantity to escape to outside the floss hole.Perfusion along with the water in the tank body 1, water level in the tank body 1 rises, the air on tank body 1 top is compressed, when being compressed to flowing of supplying water when its pressure is approaching to be equated with the feed pipe internal pressure, this air then reduces, water-supply valve 2 cuts out the water source one way valve 46 of breaking off feed pressure chamber 41 automatically and cuts out automatically, at this moment, continue to leak through micro through hole 42, so the pressure in the pressure chamber 41 descends, and the press water in the tank body 1, enter discharge chamber 414 through discharge-channel 411, and then act on valve plug 44 end face the outer rim place and valve plug 44 is risen, so floss hole 410 is unlocked, the flushing water of a large amount of high pressure in the tank body 1 through discharge-channel 411, floss hole 410 and discharge flushing toilet bowl.

As a same reason, if the water yield in the tank body 1 reaches scheduled volume in advance, because float 31 come-ups, delivery port 33 is closed, water flows and reduces, and water-supply valve 2 cuts out one way valve 46 automatically and also can cut out automatically, and low amounts of water spills from micro through hole 42, valve plug 44 and floss hole 410 against being separated, a large amount of water under high pressures are discharged flushing toilet bowls through discharge-channel 411 from floss hole 410 in tank body 1.

So, when the urinal flusher that the utility model proposes uses, open movable valve 25 as long as push the button 23 of water-supply valve 2, water in the feed pipe will pass through water-supply valve 2, flow through flushing valve 3 and enter in the tank body 1, when the water yield approaches to arrive scheduled volume or tank body 1 internal pressure and feed pipe internal pressure near balance, flowing of water just reduces, movable valve 25 is closed under the effect of closing spring 29, and current are cut off, simultaneously, in tank body 1, have under the pressure effect of pressure, valve plug 44 is raised, and floss hole 410 is opened, and the press water in the tank body 1 is discharged and flushing toilet bowl from floss hole 410 via discharge-channel 411.This moment, tank body 1 interior water was drained, and was not store water in the tank body 1 when not washing.

Figure 5 shows that second embodiment of the urinal flusher that the utility model proposes, it is identical with first embodiment, difference only is that the valve plug 44 in the flushing valve 4 is to cooperate slidably with the worn-out mouthful inboard at the 412 downside places, upper body of valve body, and has micro through hole 42 in valve plug 44.

Figure 6 shows that the 3rd embodiment of the urinal flusher that the utility model proposes, it is identical with first embodiment, difference only is that movable rod 26 upper ends do not have button, and has swing arm 218 with trunnion 217 attachings, pushing 218 on rocking arm can make movable rod 26 move down, make flange 211 on it touch dish 27, thereby movable valve 25 is opened, can be and coil the water pressure of 27 tops so that movable rod 26 homings.
