Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

Figures 1 and 2 show a sink arrangement in which a spigot 2 is mounted on the deck of a dual sink 1 of the sink, the spigot 2 being in fluid communication with a valve 4 via a conduit 3 and a connection assembly 5. The valve 4 is for example a switch valve or a stop valve which during opening allows water flowing from the water source to enter the connecting assembly 5, which water can in turn be supplied to the tap 2 via the pipe 3, and which during closing also prohibits water flowing from the water source from entering the connecting assembly 5, which in turn disconnects the water supply of the tap 2.

The details of the conduit 3, the connection assembly 5 and the valve 4 are shown in more detail in figure 3. The line 3 may be entirely a hose, for example formed by injection moulding, or entirely a relatively rigid tube (such as a metal tube, for example made of copper), or partly a hose and partly a rigid tube. The pipe 3 has a longitudinal direction and a transverse direction substantially perpendicular to the longitudinal direction. One end 32 of the pipe 3 can be inserted into the connection assembly 5 and be in fluid communication with the connection assembly 5, while the pipe 3 and the connection assembly 5 are also in sealing engagement. This end 32 of the conduit 3 is referred to herein as the insertion end 32 for clarity. The insertion end 32 may be fitted with a sealing ring to improve the sealing engagement with the coupling assembly 5. Two clasps 31 are formed on the pipe 3 near the insertion end 32, facing each other on both sides in the lateral direction of the pipe 3. One end of each catch 31 engages the body of the conduit 3 and the opposite end extends out of the body of the conduit 3 and forms a free end. The catch 31 is resiliently deformable so that an external force applied to the catch 31 generally directed towards the body of the conduit 3 (e.g. an external force directed transversely to the conduit 3 and towards the body of the conduit) can urge the free end of the catch 31 towards the opposite catch 31. However, each catch 31 always tends to return to its initial position when not subjected to an external force. When the external force disappears or is reduced to a value insufficient to resist the tendency, the tendency causes the locking member 31 to move toward the initial position, and even return to the initial position. A projection is formed on the outer surface of the other latch 31 facing away from the latch 31. In a preferred embodiment, each clasp 31 is inclined to the longitudinal direction of the pipeline 3, so that the free end of the clasp 31 is further away from the body of the pipeline 3 than the end of the clasp 31 that engages the pipeline 3.

The body 6 of the connecting assembly 5 has a first bore 61, the first bore 61 having a longitudinal direction and a transverse direction substantially perpendicular to the longitudinal direction. The two openings of the first bore 61, i.e., the water inlet 611 and the water outlet 612, are opposed in the longitudinal direction thereof and are in fluid communication. The outlet 612 can be fitted over the insertion end 32 of the pipeline 3 so that the body 6 is in fluid communication with the pipeline 2 and the wall of the first bore 61 is in sealing engagement with the pipeline 3.

As shown in fig. 4 and 5, the body 6 has a portion near the water outlet 612 formed with the ports 62 that are opposed to each other in the lateral direction of the first bore 61 and communicate with the first bore 61. The transverse dimension of the first inner bore 62 is smaller than the distance between the outer sides of the two opposite clasps 31 facing away from each other, so that during insertion of the pipe 3 into the first inner bore 61 of the body 6, the bore wall of the first inner bore 61 presses the two clasps 31 elastically deformed and brings their free ends closer to each other, so that the two clasps 31 can pass through the water inlet 611 into the first inner bore 61 together with the pipe 3. As soon as the projections of the outer side faces of the two catches 31 reach the two opposite apertures 62 of the body 6, the pressure exerted by the hole wall of the first inner bore 51 of the body 6 on the two catches 31 disappears, and the projections of the two catches 31 are snapped into the apertures 62 of the respective sides, whereby the body 6 forms a snap fit with the pipeline 3.

As shown in fig. 3 to 5, the body 6 after clamping can be easily disengaged from the snap member 31 by means of the operable member 7 configured as a press handle, for example. The collar 71 of the operable member 7 is fitted over the outer periphery of the body 6 at a portion of the body 6 near the water outlet 612, while the pair of shanks 72 of the operable member 7 are opposed in the transverse direction of the first bore 61 and are each connected at one end to the collar 71 and extend at the other end in a direction away from the collar 71 to form a free end. The pair of shanks 72 are elastically deformable to bring them closer together, and the spacing between the inner sides of the pair of shanks 72 facing each other after the closer together may be less than the transverse dimension of the first bore 61. One for each of the stems 72. During the closing of the pair of shanks 72 to each other, they respectively abut against and press the fastener 31 lodged in the corresponding aperture 62, elastically deforming the fastener 31 and progressively disengaging from the aperture 62, until the shank 72 passes through the corresponding side aperture 62, completely disengaging the fastener 31 lodged in the aperture 62, at which point the conduit 3 can be easily extracted from the first bore 61.

In addition to the stem 72 shown extending from the collar 71, other variations will occur to those skilled in the art, which also serve the purpose of forcing the snap 31 out of the opening 62. For example, in one embodiment not shown, the collar 71 is not provided and the shank 72 is formed directly on the body 6, for example in the aperture 62, with one end of the shank 72 being joined to the periphery of the aperture 62 and the other end being free and extending slightly outwardly from the aperture 62. Alternatively, in another embodiment not shown, the collar 71 and the shank 72 are located within the first bore 61, such as by forming a transverse step surface in the bore wall of the first bore 61 adjacent the outlet 612 and two opposed grooves in the bore wall, the collar 71 resting on the step surface and the pair of shanks 72 engaging in the two grooves.

As shown in fig. 4 and 5, to form a snap fit, there is a space 63 between the edge of the orifice 62 of the body 6 and the end surface 67 of the body 6 at the end of the outlet 611, so that the orifice 62 does not extend to the end surface 67. However, it will be appreciated by those skilled in the art that the present invention may be used to facilitate the smooth disconnection between two snap-fit components, as well as the smooth disconnection between two other components that are connected in a non-movable manner. For example, in one embodiment, not shown, the orifice 62 of the body 6 may extend all the way to the end face 67, leaving the orifice 62 open to the end face 67, while the insertion end 32 of the conduit 3 is a flexible tube that is elastically deformable and is not provided with the snap 31, the sealed and non-movable engagement of the two being achieved only by the tight fit of the insertion end 32 with the wall of the bore 61. In this case, by pressing the pair of handles 72 of the operable member 7 toward each other through the opening 61, the insertion end 32 of the pipe 3 is pressed, so that the insertion end 32 is elastically deformed and the tight fit with the wall of the first bore 61 is released, thereby smoothly withdrawing the pipe 3. Alternatively, in another embodiment, not shown, the aperture 62 is still formed as shown, and the conduit 3 is still in sealed and non-movable engagement with the resiliently deformable insertion end 32 in close fitting relation with the wall of the first bore 61, in which case the insertion end 32 of the conduit 3 may be pressed by pressing a pair of handles 72 of the operable member 7 towards each other through the aperture 61, such that the insertion end 32 is resiliently deformed and the close fitting relation with the wall of the first bore 61 is released, thereby facilitating the smooth withdrawal of the conduit 3.

As shown in fig. 4 and 5, the body 6 is formed with a circumferential groove 64 on its outer periphery to receive the collar 71 of the operable member 7 and to prevent the collar 71 from being longitudinally displaced. The collar 71 may be formed as a circumferentially unclosed ring, i.e. there are two ends 711, 712 in the circumferential direction. A space 713 is formed between the two ends 711, 712, the space 713 extending from one circumferentially extending end surface 714 of the collar 71 to the opposite circumferentially extending end surface (not shown). This circumferentially interrupted configuration may facilitate the fitting of the collar 71 over the body 6. The ring groove 64 of the body 6 may be circumferentially discontinuous, i.e., a stopper 641 extending from one circumferential wall of the ring groove 64 to the opposite other circumferential wall is formed in the ring groove 64. When the collar 71 is placed in the groove 74, the end surfaces of the ends 711 and 712 of the collar 71 abut against the opposite side surfaces of the stopper 641. The collar 71 thus provides a better grip on the body 6 and prevents circumferential displacement.

Of course, instead of a circumferentially broken loop 71, a loop 71 that is circumferentially continuous to form a closed loop is also possible.

Still referring to fig. 4 and 5, each stem 72 may be formed with a projecting portion 721 projecting toward the opposite other stem 72 at the inner side face thereof, the projecting portion 721 being passable through the corresponding-side aperture 62 so as to engage and press the corresponding-side clasp 31 or other configuration elastically deformable portion of conduit 3. Preferably, the protrusion 721 increases in size in the transverse direction of the first inner hole 61 in the direction away from the collar 71, so that the snap 31 can be pushed out of the opening 62 or the tight-fitting pipe 3 can be disengaged from the wall of the first inner hole 65 more easily and easily.

Further, a flange 722 may also be formed around the protruding portion 721. The flange 722 and the space 63 can form a stop in the transverse direction of the first bore 61 during the application of pressure to the shank 72 to press the nose 721 against the pipe 3 off the body 6, preventing the shank 72 from being pressed too far to cause damage to the components.

Furthermore, in order to help the pipe 3 and the body 6 align the snap 31 and the orifice 62 quickly during the engagement, a guide slope 66 is formed at the hole wall of the first bore 61, and another guide slope 311 matching the guide slope 66 is formed at the end of the snap 31 that engages the main body of the pipe 3.

As shown in fig. 3 to 5, a filter member 8 may be further provided on the body 6. The specific structure of the filter member 8 is shown in fig. 6 to 8. The body 6 has a second bore 65 transverse to the first bore 61 and communicating with the first bore 61. The nipple 83 of the filter member 8 includes a main body 831 threadably engaged with the hole wall of the second internal hole 65 and covering the second internal hole 65, and a support portion 833 extending from the main body 831 toward the first internal hole 61. The annular net-shaped filter screen 81 is sleeved on the supporting portion 833 and positioned between the water inlet 611 and the water outlet 612 in the first inner hole 61. The water entering from the inlet 611 of the body 6 passes through the filter mesh 81 to reach the outlet 612.

The outer side of the body 831 facing away from the first bore 61 may be provided with a twist handle 832 extending out of the second bore 65 to facilitate removal of the fitting 83. A sealing ring 82 may be fitted over the body 831 to achieve a good seal between the joint 83 and the wall of the second bore 65.

The bearing 833 comprises, in the embodiment shown, a bearing ring 835 which engages on an end face of the body 831 facing the first inner bore 61 and a plurality of mutually parallel rods 836 which are arranged in the circumferential direction of the bearing ring 835. Each stem 836 extends from the support ring 835 into the first bore 61 transversely to the first bore 61. The mesh-like filter screen 81 is fitted over the support ring 835 and the rods 836 with the inner peripheral wall spaced from the rods 836. This may help the water to more smoothly pass through the filter mesh 81 and be sufficiently filtered by the filter mesh 81. Preferably, a further ring element is provided at the end of the rod 836 remote from the bearing ring 825, with all the rods 836 being arranged at a spacing in the circumferential direction of the further ring element. The other ring member is provided with a stop flange 834 for forming a stop engagement with the filter mesh 81 transversely of the first bore 61, the filter mesh 81 being sandwiched between the support ring 825 and the opposing stop flange 834 to prevent the filter mesh 81 from falling off the support 833 during assembly and disassembly of the filter element 8.

Instead of the annular mesh-shaped filter screen 81, other configurations of the filter screen are conceivable by the person skilled in the art, for example a sheet-shaped filter screen or a curved filter screen. The filter screen may also be clamped, for example, on the end of the nipple 83 projecting into the second bore 65 and placed between the inlet 611 and the outlet 612 of the body 6.

Referring to fig. 5 and 6, the bore wall of the first bore 61 may be formed with a laterally projecting stop wall 68, the stop wall 68 engaging the bore wall on one side thereof adjacent the water inlet 611 and being spaced from the bore wall on the opposite side. The filter 81 extends into the first bore 61 and then rests on the stop wall 68. Thus, the water flow flowing in through the water inlet 611 passes through the filter 81 entirely due to the blocking of the blocking wall 68, and sufficient filtering is achieved.

Referring to fig. 1 to 5, the end of the body 6 where the water inlet 612 is located is connected to the water outlet 41 of the valve 4 by means of the locking nut 91 and the joint 92, so that the body 6 is in fluid communication with the valve 4. A sealing ring 93 may be fitted over the fitting 92 to effect sealing engagement of the fitting 92 with the end of the body 6. A sealing gasket 94 may also be fitted over the fitting 92 to effect sealing engagement of the fitting 92 with the lock nut 91.

It should be understood that although the description is in terms of various embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and those skilled in the art will recognize that the embodiments described herein may be combined as suitable to form other embodiments, as will be appreciated by those skilled in the art.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
