Description

The water tap that has adjustable delivery spout and action bars

Technical field

The present invention relates to water tap, especially relate to the water tap that has an adjustable delivery spout and a single operation bar.

The background of invention

The water tap that has a swiveling jet nozzle may allow a user obscure the direction of move operation bar easily, with the flow of regulating water with regulate mixing temperature.Really, be equipped with in the water tap of the standard that is fixed on the dispense spout on the faucet body in use, the user locatees the direction of oneself usually and with respect to dispense spout move operation bar, action bars typically refers to the user and on basin pond or pond and extends.Therefore for the water tap that an adjustable delivery spout is housed, the user is directed into and adopts same standard.In this case, when the direction of dispense spout moved with respect to faucet body in fact, the user obtained a diverse result.The user must determine the orientation of oneself with forward a direction, and this may be difficult to accurately observe in some cases.The user does not relocate own direction with respect to spout, because mixing drum or mixing valve are installed in the recess or cavity of fixed body of water tap usually.As a result, the acquisition of action bars be mixed to once the discharge of desired temperature distribute and the essential reference in desired position with respect to a fixed-direction of fixed body.When spout during, can observe this direction easily at a forward facing position placed in the middle.But when spout moved, this direction was just understood for the user not too easily.In addition, the position of action bars and the true bearing of dispense spout are irrelevant, and wherein dispense spout can be regulated with respect to the fixed body of valve.

When action bars is commonly referred to as the type of one " control stick " type, just become particularly evident with respect to the inconvenience of the location of fixed body rather than spout.In the water tap of a Joystick-type, action bars moves at a first direction, so that flow is lowered to a fastening position from a full flow state, and moves in the second direction perpendicular to first direction, to regulate mixing ratio or mixing temperature.Fastening position is single, and promptly water tap is only just closed when action bars moves to a middle position on fixing dispense spout.When water tap was adjusted to a position beyond the middle position, the user may feel the difficulty that will close current, may think that perhaps he has closed current, and in fact be far from being literally true, but water tap will drip.When spout when its middle position only slightly rotates, can occur this situation more frequently, and a user thinks that water tap occupy centre position and move operation bar to aim at spout.

Therefore needed is to address the above problem, thereby has user's positioning action bar correctly of the water tap of an eyelid, correctly regulating flow and temperature, and can guarantee that water tap closes fully.Thisly guarantee all should be guaranteed in the same manner for all direction of rotation of eyelid.

Summary of the invention

According to an aspect of the present invention, the recess or the cavity that are used for mixing drum is installed on the water tap are in the element that being mounted to of water tap rotated with dispense spout, and wherein this element can be regulated with respect to the fixed body of water tap again.Because this feature, the tube valve that therefore is installed in the water tap just rotates with dispense spout.When spout changes with respect to the orientation of the fixed body of water tap, be used to the also correspondingly rotation of orientation that action bars is correctly moved.The user just can come the operating operation bar by adopt its standard of getting used to adopting when operation has fixing dispense spout like this, and this will bring operation more easily.

Preferably, the orientation of mixing drum is pre-determined by the recess in the identity element of water tap, and wherein this element integrally forms its adjustable spout.

Preferably, water tap adopts the mixing drum of an open-type, described mixing drum has the transverse distribution opening, and the element that pre-determines the mixing drum orientation therein provides a circumferential area, and the dispense aperture of mixing drum is led to this zone and directly linked to each other with the inner passage of dispense spout.

Preferably, for any position assurance in the dispense spout of valve is correctly supplied with to mixing drum, the element that pre-determines the mixing drum orientation therein provides the two-way rotating hydraulic syndeton with respect to the fixed body of water tap, and wherein fixed body is connected on the service again.Preferably this rotating hydraulic syndeton comprises a centre gangway that links to each other with one of service and is a circumferential cavity of part annular at least, and this circumferential cavity is connected on other service.

Detailed description of preferred embodiment

Referring now to Fig. 1, a water tap 29 has a fixed body 1, and a rotating element 11 is installed on it, and this rotating element constitutes a dispense spout 14.One lid 26 remains on water tap 29 inboards with a mixing drum 21.Mixing drum is equipped with an action bars 25.Action bars is expressed as the form of a up-and-down rod, and is commonly referred to as the type of " control stick ".As what noticed, this action bars 25 can move along a first direction (in the plane of accompanying drawing shown in Figure 1), with the flow of the water that mixes in adjusting between full flow and the fastening position.In the drawings, control operation bar 25 is indicated on fastening position.Action bars also can move along the second direction (perpendicular to drawing) perpendicular to first direction, to regulate the mixing ratio between cold water and the hot water.

In order correctly to use water tap, the user must know the direction of motion of action bars 25.Dispense spout 14 is unique parts with an extension of giving prominence to of water tap, to indicate a clear and definite direction.Because many water taps have fixing dispense spout, so the user habitually adopts the direction with reference to control operation bar 25 of dispense spout 14.Therefore the operator adopts same direction or orientation by the light of nature or intuitively, even dispense spout is adjustable.But in this case, the known water tap that has eyelid may mislead the user as shown in Figure 2.Direction shown in the dispense spout 14 changes, as represented in 1 shown in the dotted line first position and the difference between the second place placed in the middle.The moving direction that can notice the action bars 25 of the mixing drum in cavity of the fixed body 1 that is installed in water tap or the recess always remains unchanged, and therefore just has a transformable relation with respect to dispense spout 14.As shown in Figure 2, when spout rotated, two perpendicular axis of movements 31,33 of control operation bar 25 tilted with respect to spout 14, and action bars 25 tilts with respect to spout 14 when in the closed position.

In the present invention, as shown in Figure 4, in fact the mixing drum 21 that is extended with control operation bar 25 is installed in the cavity or recess 35 of a rotating element 11.Element 11 has the dispense spout 14 that integrally forms.Mixing drum is remained in the element 11 by lid 26, is to be fixed on the rotating element 11 in this case.The longitudinal axis of mixing drum 21 aligns with the rotation of spout 14.Therefore, when dispense spout 14 was regulated with respect to fixed body 1, rotating element 11 also rotated, and mixing drum 21 also rotates with these parts, as shown in Figure 3.Therefore, two axis of movements 31,33 of action bars 25 just rotate with respect to fixed body 1, and keep constant or fixing with respect to spout 14.Tie up among Fig. 3 with respect to this fixing pass of spout and to illustrate by the contrast of two groups of perpendicular axis 31,33.One group is at the dotted line place corresponding to the dotted line nozzle exit area, and second group is at the solid line place corresponding to the solid line nozzle exit area that rotates.Action bars 25 also keeps its orientation with respect to dispense spout 14 own.If spout 14 rotations, action bars 25 are just with the spout motion, as shown in Figure 3.Therefore, the user determines the direction that it must move operation bar 25 with reference to the direction of dispense spout, to regulate the flow and the temperature desired of water.He is accustomed to doing when use has fixing dispense spout just for this.In addition, action bars 25 always is aligned on the spout 14 when in fastening position.

Represent recess or cavity 35 in the rotating element 11 referring now to Fig. 4 and 6.The cavity 35 that holds mixing drum 21 provides a circumferential area or gap 12, in circumferential area to outside offer the transverse distribution opening 22 of mixing drum 21 (it is an open-type).Gap 12 directly links to each other with the passage 13 of dispense spout 14.

Obviously, in the mode of revising, dispense spout 14 can be and rotating element 11 element independently structurally, and suitably be connected on the element 11.In addition, the recess or the cavity 35 that hold mixing drum 21 can not be formed directly in the rotating element 11, and are formed on the structure independently in the element, and are installed in the rotating element 11 again.

In order to ensure correct conveying, between the rotating element 11 of water tap and fixed body 1, a two-way hydraulic pressure is set and is connected to mixing drum 21.This connection can be better referring to Fig. 5 and 6.Rotating element 11 provides a part 15 of protruding, and this projection provides a central opening 16 and a circumference ring cavity 18.Central opening 16 links to each other with one first inlet 23 that leads to mixing drum 21 through a passage 17, and circumference ring cavity 18 then links to each other with second inlet 24 of mixing drum 21 through a passage 19.

The fixed body 1 of water tap itself has a cavity 2, and this cavity rotatably holds the projection 15 of rotating element 11.Fixed body 1 has a central opening 3, and this opening links to each other with a junction position 4 of one first conveyance conduit (not shown); Also have a circumference ring cavity 5, it links to each other through a junction position 7 of a passage 6 with the second conveyance conduit (not shown).Described part is designed like this, and when rotating element 11 was installed on the fixed body 1 of water tap, central opening 3 and 16 can be connected with each other logical, and

chamber

5 and 18 also is connected with each other logical.Owing to is provided with seal 8 and is provided with sealing ring 9 in the opening 3, so each passage is a waterproof around ring cavity 18.Can guarantee that with this mode of each position of rotation to(for) dispense spout 14 is to mixing drum 21 feeding cold waters and hot water.

The projection 15 of rotating element 11 also provides a circumference annular groove 20, holds a clamp screws 10 in it, and this screw is screwed into through fixed body 1 spiral.Screw 10 mechanically links rotating element 11, makes its axial location, but does not hinder its rotation.Annular groove 20 can be an incomplete circular arc, so that the rotary area that restriction rotating element 11 and dispense spout 14 are allowed.Correspondingly,

circumference ring cavity

5 and 18 also can be the incomplete circular arc along its circumference.

Should understand that in other embodiments fixed body 1 can adopt different structures with the bidirectional hydraulic connection between the rotating element 11, this is known in the prior art that hydraulic pressure connects.And, can hold a plurality of screws 20 around the some parts of groove 20 circumferentially, so that element 11 is rotatably fixed on the fixed body 1.

In addition, control operation bar 25 is expressed as a straight post or a bar, can be mold formed and use same internal valve mechanism but use it for some.For example, action bars 25 can form profile to dispense spout, as what seen in many known water taps.

The central fastening position of " control stick " action bars 25 is always corresponding to the direction of eyelid 14.This fastening position is selected to the user by always confirming as to have reached fully and close to dispense spout move operation bar.But for some application, fastening position can instead be established, for example lift or leave spout 14 round about or for some application in addition set for depart from 90 the degree positions.In all situations, fastening position for good and all is provided with respect to spout.Secondly, the orientation of operation is also set with respect to spout.Therefore the present patent application provides two main advantages for the valve that has " control stick " formula action bars.

The present invention also can be applicable to be different from the water tap of shape shown in Fig. 2～6 and valve operation certainly.For example, Fig. 7 has represented how the present invention is applied on the water tap, and wherein its fixed body 1 is not so-called " control stick " type.Fig. 7 has represented a valve, the quadrature-axis motion that it moves into the axis B-B rotation of trip temperature adjusting and moves into capable Flow-rate adjustment.Handle can form profile attractive in appearance, so that move into the quadrature-axis motion that the axis B-B of trip temperature control operated and moved into capable flow-control.In addition, in this example, mixing drum is installed on the axis B-B with respect to rotating element 11, and this axis constitutes an angle with respect to the rotation A-A of eyelid.Two axis A-A and B-B all be positioned at drawing and with the central vertical of spout 14 in the face of neat.These arrange provable in some cases is preferred, particularly when considering some shape of control operation bar.In such water tap, have many fastening positions along a circular arc, wherein action bars is in the position of portion once of leaving axis B-B.Like this, action bars does not just need to align with spout and cuts out water tap fully.The user still needs an orientation to come design temperature correctly.Normally, hybrid position is the central authorities of adjustable region in operation, and is placed in the middle for a fixing spout.In the present invention, the central authorities of adjustable region be locate with eyelid and with its rotation.The present patent application provides the orientation of proper operation control operation bar 25.

Fig. 8 represents another embodiment of the present invention, and it has adopted is not a ball valve of a mixing drum form.In this embodiment, rotating element 11 has a recess 41, and this recess is configured as in the downstream of

passage

17 and 19 and holds valve seal 43, and described seal is seal ball-valve 44 closely.Ball valve 44 has a control lever 46, and it passes and covers 26 and be bonded on the action bars 25.Ball valve 44 is not the mixing drum form, and only is mounted in the recess 41 that forms suitably of element 11.Yet when spout 14 was regulated, element 11 also rotated and is carrying ball valve 44 and action bars 25, thereby the operation of action bars 25 is always with respect to spout 14 location.The actual inside driving element of ball valve 44 is known in the art, and does not constitute a part of the present invention.

Be to be understood that the embodiment that the invention is not restricted to as example description and expression.Under the prerequisite that does not break away from the scope of the present invention that limits by appended claims and essence, other variation and to revise also be possible.
