The specific embodiment
In Fig. 1, the preferred embodiments of the present invention comprise startup member (2), and this startup member (2) comprises partial flushing button (4), full push button (6), linking arm (8) and push rod (10) generally.Containment member (12) comprises float seal (14) and cantilever (16) generally.Liquid outlet (18) is positioned on the apparatus main body (20).
Partial flushing button (4) and full push button (6) are pieceable at the top, and are set to contact with a side of linking arm (8).An other side of linking arm (8) is equipped with extension bar (11).Unless part and full push button (4) and (6) are pushed by the user, they can not apply any pressure to the top of push rod (10).Partial flushing button (4) and full push button (6) are preferably mounted on the lid (not shown) of water tank, and also can be visible by the user outside being exposed to.Conventional the same in remainder and the prior art of device, major part is suitable for being contained in the water tank, and can submerge under water when water tank is full of.
Extension bar (11) is by coaxial the surrounding of push rod (10), and can regulate up or down along the longitudinal axis.Therefore, the length of extension bar (11) can change as required, thus the distance between linking arm (8) and the cantilever (16) be can select and can determine according to the degree that extension bar (11) prolongs.Push rod (10) and extension bar (11) preferably have a plurality of holes (22).Above-mentioned hole (22) is separated from one another with predetermined interval along the axle of push rod (10) and extension bar (11).Push rod (10) also preferably includes the lock pin (not shown), in case to guarantee that extension bar (11) has extended to required length and just can be locked into suitable position.Alternatively, lock pin can be locked onto a selected position, so just can extension bar (11) be adjusted to the optimum position with respect to linking arm (8) and part and full push button (4) and (6) by described lock pin being interted above-mentioned hole.Push rod (10) and extension bar (11) can pass first guide rod (26) and second guide rod (28) respectively, so that keep their motion to come down to straight line when they are started by any one push button.
In Fig. 2, discharging valve device is shown in closed position.This position and such situation are interrelated, and promptly water tank is full of water to required horizontal plane and be ready to be activated so that partial flushing or full flushing to be provided.The straight line that linking arm (8) will start member (2) moves downward the pin joint (30) that is delivered to push rod (10), contacts with the start end (34) of cantilever (16) at this table body (32) of locating push rod (10).Cantilever (16) expectation links on main body (20) around pivot (36).Pivot is equipped with float seal (14) on the sealed end of cantilever (16), and it can be clearly seen in Fig. 1 by liner (38) and float (40) forms.Float seal (14) has enough weight to the sealed end that is pressing down cantilever (16), contacts thereby liner (38) is descended and reach with ring exit edge (42) after washing the water tank emptying entirely.Thereby the sealed end of cantilever (16) can comprise the antelabium (44) that the upper surface that is suitable for bearing liner (38) is exerted pressure help seal fluid outlet (18).When water tank was full of water, the downward power that acts on liner (38) upper surface was enough to overcome any buoyancy that acts on float (40).
Main body (20) is empty and is integrated with the inside overflow ducts (46) that extends to outlet (50) from overflow inlet (48).Should understand outlet (50) and communicate so that the current that go out from Cistern flushing advance flush toilet, and the water that flows down overflow ducts (46) also can flow to toilet with the flush toilet (not shown).Overflow ducts (46) comprises telescopic extension socket (52) coaxial with overflow ducts (46) and that can regulate up or down along the longitudinal axis of overflow ducts (46).Therefore, the height of overflow inlet (48) can change as required, and the horizontal plane that arrives of the water in the water tank can be selected and definite by the degree that telescopic extension socket (52) are extended like this.Telescopic extension socket (52) can comprise adjustable track (53) so that extension socket (52) can progressively be regulated.Provide locker (56) in case to guarantee that extension socket (52) has extended to required height, it just can be locked into adjustable track (53).Telescopic extension socket (52) comprises that also O RunddichtringO (54) is (Fig. 1) to guarantee that water can be from flow through any gap between overflow ducts (46) and the extension socket (52) of water tank.First guide rod (26) that provides the peripheral edge that is connected to main body (20) is a straight line with the motion that keeps push rod (10), and second guide rod (28) to be connected to the peripheral edge of telescopic extension socket (52) and to extend out with the motion that keeps extension bar (11) from the peripheral edge of this telescopic extension socket (52) be straight line.
Said apparatus can further include one or more additional overflow ducts (58) that parallel with aforementioned overflow ducts (46) (Fig. 1).Additional overflow ducts (58) can be connected to chamber (60) with modular mode.Similar with main overflow ducts (46), additional overflow ducts (58) can have the telescopic extension socket (not shown) that permission is regulated the height of each overflow inlet (62), and perhaps Fu Jia overflow ducts (58) can be the length of fixing.No matter whether arrive selected fill level face, additional overflow ducts (58) also further protects water tank to prevent overflow if water tank filling-valve fault and water continue to flow to water tank.
When make position and water tank are full of, the weight of water that acts on the upper surface of liner (38) will keep liner (38) to prop up the ring exit edge (42) of liquid outlet (18).This will cause the start end (34) of cantilever (16) act on push rod (10) pin joint (30) table body (32) thus make push rod (10) remain on the top the position.
See Fig. 3, this figure has illustrated the structure of device when the user has started horizontal plane in partial flushing and the water tank and descends from the full water plane.User pressure part push button (4) actuating section flush position.When complete pressing part push button (4), it presses to the mobile L of linking arm (8) with respect to extension bar (11) and push rod (10)
1Distance and the cantilever (16) that causes pivot float seal (14) is risen θ
1Distance.As long as be in the position of partial flushing, water will be from water tank through liquid outlet (18) and emptying, because the sealing between liner (38) and the ring exit edge (42) is broken.Therefore, the horizontal plane in the water tank will descend.Sealed end and liner (38) on every side and the outflow of the outer water of liquid outlet (18) will cause acting on the power that remainder is downward of the upper surface of containment member (12).Should consider the tangible Venturi effect (venturi effect) that causes by the outer current of liquid outlet (18) in addition.This effect that is added on other downward power will impel liner (38) near closed position.Therefore, being transformed into the partial flushing position from make position needs the user to push fully and retaining part push button (4) usually, so that the water of the enough minimum volumes of wanting of energy only is used for clearing up liquid and cotton paper refuse.When the user unclamped partial flushing button (4), partial flushing button (4) will return to its normal position and water will stop to flow.The user can be immediately again according to and the retaining part push button circulate and remove light waste to be used for next time partial flushing.Therefore, need not before carrying out flushing next time, to wait for that the water arrival certain level face in the water tank has just satisfied the demand of next time washing immediately.
Fig. 4 indication device is in full flush position.When pushing full push button (6), the user adopts this position.Full push button (6) will move with the linking arm (8) of extension bar (11) and push rod (10) connection and compare distance L
1Bigger distance L
2Cause cantilever (16) that float seal (14) is risen θ like this
2Distance.Being transformed into full flush position from make position only spends less than a second usually, is that the user is used for pushing fully the employed time of full push button (6).After full flushing made water tank emptying, full push button (6) just returned to its normal position.
When full flush position because the sealing between liner (38) and the ring exit edge (42) will be broken, water just can be from water tank through liquid outlet (18) and emptying.Horizontal plane in the water tank can descend.At full flush position, although water can flow around liner (38) and sealed end, but liner (38) will be positioned at a kind of like this position that is not subjected to the distance of above-mentioned Venturi effect effect, even so that to have also be that seldom this downward masterpiece is used for it.In addition, because float (40) is surrounded by water, it is different from the situation when the partial flushing position, so float (40) will have the upwards buoyancy of effect that acts on its surface.Although horizontal plane is higher than sealed end and float (40), what act on cantilever (16) in the full flush position also will make it remain on this position with joint efforts.
When horizontal plane drops to certain point, no longer provide the leading power that makes progress that accounts at this float (40), this power is the power when having dropped to the position of float (40) when horizontal plane normally, and the downward power that acts on sealed end will make cantilever (16) move to make position.At above-mentioned point, the water of full flush volume will be discharged from water tank.After full flushing has made the water tank emptying, float seal (14) itself will provide a quality to help that cantilever (16) is moved to make position.Be full of water tank and be flushing in the future when ready when horizontal plane is elevated to, the downward power that acts on the assembling of liner (38) will make it remain on make position.
Said apparatus can be made by any suitable method by any suitable material.For example, the various assemblies of said apparatus can be annotated by the polymeric material mould and make.Though described the present invention, obvious same invention can be by many different from changing.This change should not be counted as and run counter to the principle and scope of the present invention, and conspicuous for a person skilled in the art all distortion are regarded as being included in the scope of this claim protection.
