Description

Improved water spraying unit of water box in lavatory

The present invention relates to improved water spraying unit of water box in lavatory, these improvement are embodied in and improve the bath device that uses at present, especially make these bath devices can optionally stop bath, with using water wisely.

One of summary of the invention is, such bath utensil has the bleed off pipe guide groove, and it is preferably arranged vertically, and does not rotate.

Another content of invention is, such bath device also has the system that the flush valve with differing heights is complementary, and this systematic economy effectively and simple installation.

Some other improvement is, the axis of drawing the cork can move by mode preferably, and in the time of needs, the axis of drawing the cork can be along moving with respect to the axis of bleed off pipe and the eccentric axis ground of bath device bell-jar.Make and prevent the member that rotates and draw the cork in aggregates.

Others when water is excessive from trough rim, flow into water tank in advance in order to stop air, can make the closure element between float and the bath device bell-jar be linked to be an integral body.Like this, when bath finished, float descended, rather than descended before this, thereby obtained better economic benefits.

Same applicant has introduced the present invention in utility model U-9101203, apparatus of the present invention are used to interrupt the flush valve bath and describe, in this device, bath control member or bath knob have the bar of a butt head bending, and its free end with bleed off pipe links to each other.Start button is bearing on the spring with the bent stick coaxial line, the guide groove of configuration bent stick on this assembly.When needs interrupt bath, just press the opposite button of single spring effect with coaxial line, like this, the sweep of bar just is applied to pressure on the bleed off pipe, and bleed off pipe just descends again, thereby flush valve is closed.

Can also observe, for the degree of crook of accurate adjusting with respect to the described bar of the entrance of bent stick on the bleed off pipe, making interrupts washing by water is accurately carried out, so, it is necessary being equipped with the bent stick length adjustment piece, these length adjustment piece are used for regulating tank and cover to the distance between the bleed off pipe, although bleed off pipe also is equipped with length adjustment piece.

In other flush valve, it is simple in structure to draw the cork, and includes only a bent stick, and the bent stick horizontal component inserts bleed off pipe top, and vertically the free end external member of part is tapping, its extraction can be washed by water.

Brief says, improvement to water spraying unit of water box in lavatory constitutes content of the present invention, these improvement are, bleed off pipe guide groove system is provided, this system is the projection that is arranged in the periphery of bleed off pipe fully opposed to each other by a pair of, each projection moves in all can a vertical guide groove on neck, is formed by the top of bath device housing or bath device bell-jar.These guide grooves are broad " C " shape straight troughs, and they are parallel, and bath device neck tubular wall obtains relatively or by widening, and guide groove does not arrive the bell-jar upper surface, to avoid water to flow into by guide groove and to interrupt bath.

Because bleed off pipe is furnished with guide groove, therefore, height adjusting system is configured in and together the connector of drawing the cork on, preferably limited by being "T"-shaped member, its vertical portion is assigned tapping hole; The termination of bar links to each other with described hole exactly, and this bar is furnished with the screw thread that is equal to mutually, and links on start button or bleed off pipe draw the cork by axial manner.The screw thread of "T"-shaped member only arrives to connect use upper area, because elastic ring is housed, or locknut formally tightens, and like this, selected position just is locked, with "T"-shaped horizontal component go up or under the position continuous.

According to optional needs, fact proved, unless press start button as next step operation, unless unclamp make drawing the cork of valve closing and finish close outside, the device that configuration can arbitrarily be closed is necessary.

According to the present invention, open some holes at the upper substrate of bath device housing or bell-jar, one of feature of the present invention of people's acquisition that Here it is.In this case, current descend float and close with formation by these holes.

" T " member works in the bleed off pipe upper opening, this point is described in this section the 3rd paragragh, described "T"-shaped member also can be furnished with a kind of different structural member, the vertical part of "T"-shaped member can be cancelled, like this, it can barre be tightened in out in one of tapping hole on horizontal component, and this new layout can prevent to draw the cork and the coaxial phase shift of washing by water and producing in the water tank between the device.

In addition, drawing the cork comprises that a cannelure preferably, its function are to stop the rotation of drawing the cork, and avoids horizontal component equally to unclamp from bar with drawing the cork, and can not calibrate desired height thereby make when washing by water the device operate as normal.For this reason, for example screw of a kind of member must be arranged also, be fixed on the described tubular shell, simultaneously, its free end enters cannelure easily.In a single day this operation regulates the position and just can carry out.

Other improvement of having carried out relates to a kind of closure element, and this closure element in this case, lacks some perforates at its base portion on bleed off pipe and the bath device bell-jar between neck one guide groove or the tubulose converging portion.This closure element preferably by be configured in around the bleed off pipe and float on cone-shaped component or similar component form, like this, when bleed off pipe and other are linked member on the bleed off pipe and are raise, just make the current water tank, the improvement of cone-shaped component is to be regulated well in the opening of tubulose converging portion, stops air to enter the inside of bath device bell-jar in advance.Therefore, water in the water tank dashes fully just to be put and can be guaranteed, this is because highly do not reach bath device bell-jar lower opening, thereby air can not enter the inside of this bath device bell-jar, like this, when the height of water arrived bath device bell-jar lower opening, closure element did not remain on the trough rim edge, is beneficial to described member and closes.

Below, we do further introduction to invention, in order to understanding the present invention better by unrestricted embodiment and with reference to accompanying drawing.

Fig. 3 is the vertical front elevation drawing of bleed off pipe, and this illustrates in order to be complementary with dissimilar water tank, the device that gives the standing wave dynamic height face portion fixed thereon that is used for regulating the control water tank.This device is made up of the tapping bar basically, and this tapping bar is continuous with drawing the cork by its upper end, and links to each other described "T"-shaped upper shed place that is connected to bleed off pipe with "T"-shaped member by its lower end.

Fig. 4 is the lateral view of the bleed off pipe shown in Fig. 3.

Fig. 5 and 6 is "T"-shaped upper end amplification profiles, is linked to each other with "T"-shaped upper end by the bar of drawing the cork that descends.

Fig. 7 is the sectional drawing of combining with tank lid of drawing the cork.

Fig. 8 is the front sectional elevation that is different from the section of drawing the cork that has illustrated in the earlier drawings.This is drawn the cork and links tubular shell inside, and tubular shell is fixed on the water tank of the present invention.

Fig. 9 is an A-B sectional drawing among Fig. 8.

Figure 10 is fixed on vertical front elevation drawing that the cover of one on the water tank is drawn the cork, and this cover is drawn the cork and also comprised the upper part of bleed off pipe.Described this cover is drawn the cork and is at first linked to each other by the tapping bar, and link on the described member its underpart, works in the opening of usefulness usually on bleed off pipe, and described member has the difformity shown in Fig. 3 and 4.

Figure 11 is a partial view, and this accompanying drawing mainly illustrates bar and is located on member in the bleed off pipe opening and links to each other along eccentric position.

Figure 12 is the water spraying unit of water box in lavatory front sectional elevation, this illustrates the shutdown system between the neck opening on the cone-shaped component that is configured in the bleed off pipe and the device bell-jar of washing by water, for avoiding air to enter water tank too early, when bleed off pipe raises, the water in the water tank is flowed out.

Figure 13 is the part sectioned view of bath device, and this illustrates with slightly different shown in the earlier drawings but the identical shutdown system of effect.

Figure 14 is the water spraying unit of water box in lavatory view that is specifically designed to high level cistern.This water tank does not comprise float, because this water tank does not need float, although this water tank also comprises the shutdown system shown in the earlier drawings.

Figure 15 is similar to the accompanying drawing shown in the earlier drawings, and in this accompanying drawing, shutdown system has some little differences.

Figure 16 is a high level cistern bath device view, and the shutdown system that is used for stoping air to enter too early is different from the shutdown system shown in the earlier drawings.

With reference to the numbering of using in the accompanying drawing.We see that bath device bell-jar or housing comprise the last neck 2 of the guide hole of bleed off pipe 3.Guide hole in axial direction disposes.Because one of above-mentioned member relatively moves facing to another, these members then have a kind of cylindrical cross-section that can brisk adjustment.

For fear of the relative rotation between the above-mentioned member, and can control the water tank fluctuation thus easily highly, see as the front, bleed off pipe 3 lower parts are furnished with opposed a pair of projection 5 fully, each projection works in one of two guide grooves 6 that are " C " shape, these guide grooves are axial identical enlarged, bleed off pipes as shown in Figure 2 of the cylindrical neck portion 2 of bath device housing or bell-jar 1.

People see that already bath device bell-jar 1 is lower than the ring 8 at water tank water export edge to be fixed, and a cover closure element and float work in above-mentioned bell-jar, and its lower part 9 with bleed off pipe 3 links to each other.The lower part of bleed off pipe 3 is furnished with screw thread 10, so that close barrier film by nut installation outlet place disc; Float and to close barrier film not shown is in order to avoid accompanying drawing is complicated.

By Fig. 3 and 7, we can be clear that, utilize label to be 11 "T"-shaped and limit the regulating part of regulating draw the cork height or the fluctuation of control water tank.Member 11 to be "T"-shaped vertical part 12 are tubuloses, same level part 13 connects together, it is furnished with tapping hole, is used to connect from water tank the draw the cork lower end and the free end of the bar 14 that vertically descends, and described bar 14 has the below section 15 that is certain-length of tapping.Barre 14 roughly is tightened in "T"-shaped, like this, just can be installed on the ideal height by barre 14, that is to say, is installed in the upper part of bleed off pipe 3 openings 16, when rising is drawn the cork, makes bleed off pipe 3 temporarily raise, at this moment just bath.Unclamp in case draw the cork and come back to initial position, member 11 just is bearing in the place, lower edge of opening 16.

If handle along the opposite effect direction of drawing the cork with spring jack-up, so, member 11 descends bleed off pipe 3 again, and makes flush valve close or interrupt washing by water.

With reference to Fig. 4, we see that the vertical part 12 of "T"-shaped member 11 preferably has certain-length, and for example, when water tank is drawn the cork when extracting out fully, described member 12 is not widened the position from bleed off pipe and extracted out, so that use guide hole preferably as.

In addition, can open some holes 17, put with dashing of water in the easy interruption water tank at the upper substrate 18 of bath device 1 bell-jar or housing.

For the position of fixed bar 14 and keep it and regulate length, make "T"-shaped 11 and elastic ring 19(sees Fig. 5) in aggregates, perhaps will encircle 20 and formally connect together.Tapping thread on the bar 14 is arranged on it, is known as this cover member of automatically fastening nut effect itself.Can obtain the position of above-mentioned bar 14 when tightening jam nut 21 in advance, described jam nut 21 is screwed in the tapping position (referring to Fig. 3) on the bar 14.

22 markedness 23 of drawing the cork shown in Figure 7, when being adjusted to the ideal operation state, mark 23 is just notified installation personnel.

When addressing bath device operating characteristic, we see in front, are desirable in some cases, when to the action interrupts of drawing the cork, that is to say, unclamp and draw the cork, just can interrupt in the water tank dashing of water and put, thus using water wisely in a large number.Situation that the front addressed that Here it is in this most preferred embodiment, owing to basic 18 open some holes 17 on the bell-jar of bath device or housing, just obtains above-mentioned desired result.

The current of flowing through hole 17 and flowing to outlet opening descend float, and therefore, as what addressed, bleed off pipe 3 declines that link to each other with float are so barrier film is closed in employing on the outlet opening limit.

Draw the cork and 22 can vertically move in the tubular shell 24,, described housing is fixed on the tank lid 25 by nut 26 in guiding; There is one to make the spring 27 of drawing the cork and resetting in the bottom of this tubular shell.

Other improvement of the present invention (seeing Fig. 8 to Figure 11) concentrates on newly draws the cork 28 and constitute holistic height adjusting system with member 29.Member 29 works at bleed off pipe 3 openings 16 places, and this member 29 comprises some tapping holes 30, and the lower curtate 15 of bar 14 is arranged in one of some holes (shown in surpassing), and the other end of bar 14 is fixed on draws the cork on 28.

Drawing the cork 28 has a side to comprise a cannelure 31, is fixed on the screw 32 on the wall of tubular shell 33 or the termination of other similar component and inserts in this cannelure 31, draws the cork with respect to the rotation of tubular shell 33 so that stop preferably.

According to this layout, or rather, because the member 29 in opening part 16 effect of bleed off pipe 3 is improved, application of the present invention is just more extensive because no longer need case edge and bath device bell-jar and bleed off pipe 3 with draw the cork coaxial.Draw the cork and be furnished with to descend longitudinally reinforcing rib, these reinforcing ribs can be useed mark as, when this member is tightened on the bar 14, determine the optimum Working that has reached according to described mark.In drawing the cork shown in Fig. 7,, determine the adjusting of this duties by the mark on drawing the cork 23 as what address previously.

In addition, for avoiding drawing the cork 28 rotation, can stop 28 the rotation of drawing the cork by tubular shell 33, tubular shell inside for example has polygon-shaped, and draws the cork 28 same cross-sectional complementation, thereby no longer needs cannelure 31 and screw 32.

Now, if we concentrate bath device bell-jar 1 and bleed off pipe 3 are described, just can find, corresponding float 35 links to each other with bleed off pipe 3, release to be easy to that water is dashed fully from water tank, close and be configured on the float 35 and around bleed off pipe 3, when Water flushing for cistern, described this member 36 is closed the opening 37 of neck 2 with conical member 36.Bleed off pipe 3 and other member linked on this member 36 vertically raise, and like this, just can wash by water.In this case, close with member 36 and will be well cooperate with the opening 37 of the last neck 2 of bath device bell-jar 36, thereby avoid air to enter in advance in the bath device bell-jar 1 in mode preferably, this just makes float 35 descend in advance, can not make water from water tank fully towards releasing.According to this layout, especially owing to close with conical member 36, before height of water level arrived bath device bell-jar 1 lower opening, air just can not enter inside.Therefore, in the time of rising bleed off pipe 3, water just dashes and releases, like this, not only using water wisely but also safety, therefore, before all water were discharged, bleed off pipe 3 did not drop to their initial position again with other member that links to each other with it.

Although stop air to enter too early in the bath device bell-jar 1,, still to be closed just and can be achieved the goal with conical member 36.Also can adopt other different modes, example is such as shown in Figure 13.Annular lip 38 of lower edge configuration of neck 2 on bath device bell-jar 1, when rising bleed off pipe 3 discharge waters, annular lip 38 is arranged in complementary annular notch 39, and this annular notch 39 is arranged on by float 35 and bleed off pipe 3 and forms at an angle the section.

Accompanying drawing 14,15 and 16 illustrates the different bath device of high level cistern, they do not dispose float 35, because no longer need float 35, when rising bleed off pipe 3 makes the water discharging, as other water tank, close to avoid air to enter the inside of bath device bell-jar 1 in advance by similar approach, like this, just obtain and be equipped with other the same good effect of device of washing by water.
