Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water outlet fittings, in particular to a faucet and a water supply structure thereof. BACKGROUND

[0002] The current internal water supply structure of the faucet is generally a silica gel pipe connected with a plastic joint. The silica gel pipe and the plastic joint are prone to aging after long-term use, and the sealing effect is poor. Water leakage points are easily formed at multiple connection points, resulting in many water leakage points and poor reliability. Moreover, the silica gel pipe has an odor after long-term use, which affects the water quality. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a faucet and a water supply structure thereof to solve the technical problems of many water leakage points and odor in the prior art.

[0004] To achieve one or part or all of the above purposes or other purposes, the present application provides a water supply structure, which comprises a mounting boss, a first connecting piece, a second connecting piece and a first water pipe. One end of the first connecting piece is rotatably connected to the mounting boss, the other end of the first connecting piece is connected with the first water pipe, and the other end of the first water pipe is connected with one end of the second connecting piece.

[0005] Preferably, the first water pipe is a stainless steel pipe.

[0006] Preferably, the first water pipe has a first end portion and a second end portion. The outer wall of the first end portion is provided with a first clamping groove, and the first clamping groove is provided with a first sealing ring. The first end portion of the first water pipe extends into the pipe opening of the first connecting piece, and the first sealing ring abuts against the inner wall of the pipe opening. The outer wall of the second end portion is provided with a second clamping groove, and the second clamping groove is provided with a second sealing ring. The second end portion of the first water pipe extends into the pipe opening of the second connecting piece, and the second sealing ring abuts against the inner wall of the pipe opening. In this way, the sealing performance of the connection between the first water pipe made of stainless steel and the first connecting piece and the second connecting piece is achieved through the design of the sealing rings at both ends, thereby avoiding water leakage.

[0007] Preferably, the first clamping groove is at least two, and the first sealing ring is also provided with at least two corresponding. The second clamping groove is at least two, and the second sealing ring is also provided with at least two corresponding. The number of the first sealing ring and the second sealing ring can be increased or decreased according to actual needs.

[0008] Preferably, the pipe opening of the first connecting piece is provided with a first limiting step capable of resisting the first end portion of the first water pipe, and the pipe opening of the second connecting piece is provided with a second limiting step capable of resisting the second end portion of the first water pipe. In this way, the two end portions of the stainless steel pipe are fixedly limited, and the stable installation of the first water pipe is achieved.

[0009] Preferably, the outer diameter of the first water pipe is smaller than the outer diameter of the pipe mouth of the first connecting piece and the second connecting piece. Since the thickness of the stainless steel pipe is thin, the outer diameter of the stainless steel pipe is smaller than that of the silica gel pipe, that is, the height of the stainless steel pipe is lower, so that the outer diameter of the faucet can be reduced.

[0010] Preferably, the first connecting piece and the second connecting piece are both straight angle bends.

[0011] Preferably, the mounting boss has a first mounting hole penetrating in the axial direction, one end of the first connecting piece is rotatably mounted in the first mounting hole through a fastener, and a second mounting hole is further provided in the side wall of the mounting boss in the radial direction, and the second water pipe can be installed in the second mounting hole. In this way, two water flows are divided by one mounting boss, so that the user can select different water outlets according to needs. The water inlets of the first water pipe and the second water pipe can be connected to the same water source, facilitating simultaneous water use at different positions, or can be connected to different water sources, for example, one water pipe is connected to tap water and the other water pipe is connected to purified water, facilitating daily washing or drinking.

[0012] Preferably, the two ends of the second water pipe are connected to a third connecting piece and a fourth connecting piece respectively, the third connecting piece and the fourth connecting piece are both straight angle bends, one end of the fourth connecting piece is rotatably arranged in the second mounting hole, and the other end of the fourth connecting piece is connected to the second water pipe.

[0013] Preferably, the second water pipe is a stainless steel pipe. The sealing effect is improved, the water leakage points are reduced, and the odor is avoided.

[0014] Preferably, the first connecting piece and the fourth connecting piece are both provided with a drip-proof component that allows water flow when in use and blocks water flow when not in use. When the faucet is in normal use, water flows out through the first water pipe, the drip-proof component and the second connecting piece, and when not in use, part of the water is stored in the first water pipe or the second water pipe. To avoid the stored water flowing out through the second connecting piece or the fourth connecting piece and causing dripping, the water inlet position of the drip-proof component that communicates with the first water pipe is higher than the water outlet of the first water pipe, and the water inlet position of the drip-proof component that communicates with the second water pipe is higher than the water outlet of the second water pipe. In this way, the stored water cannot climb into the drip-proof component and drip out under the action of no water flow, and when in normal use, the inflowing water flow drives the stored water to flow and climb into the water inlet of the drip-proof component, realizing communication with the first connecting piece and the fourth connecting piece and ensuring water flow.

[0015] The embodiment also provides a faucet including the above-mentioned water supply structure.

[0016] The implementation of the embodiment has the following beneficial effects:

[0017] In the present application, the water pipe in the faucet is designed as a stainless steel pipe, abandoning the traditional silica gel pipe, so that the entire water supply structure has fewer leakage points, and the outer diameter of the stainless steel pipe can be designed to be smaller, which, when applied to the faucet, reduces the internal height and thus the thickness of the faucet, and the stainless steel pipe does not have any odor after long-term use, ensuring the water quality.

[0037] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0038] With reference to Figures 1 to 2 The water supply structure provided by the embodiments of the present application comprises a mounting boss 10, a first connecting piece 20, a second connecting piece 30, and a first water pipe 40. One end of the first connecting piece 20 is rotatably connected to the mounting boss 10, the other end of the first connecting piece 20 is connected to the first water pipe 40, and the other end of the first water pipe 40 is connected to one end of the second connecting piece 30.

[0039] In the embodiments of the present application, the first water pipe 40 is a stainless steel pipe. The water pipe in the faucet is designed as a stainless steel pipe, abandoning the traditional method of using a silica gel pipe, so that the water supply structure has fewer leakage points. Moreover, the outer diameter of the stainless steel pipe can be designed to be smaller, and when applied to a faucet, the internal height is also reduced, thereby reducing the thickness of the faucet. In addition, the stainless steel pipe does not have an odor after long-term use, thereby ensuring the water quality.

[0040] In the embodiment, the first connecting piece 20 and the second connecting piece 30 are both right-angle elbows, and the first water pipe 40 is a straight pipe having a first end portion 41 and a second end portion 42. The outer wall of the first end portion 41 is provided with a first clamping groove 43, and the first clamping groove 43 is provided with a first sealing ring 44. Similarly, the outer wall of the second end portion 42 is provided with a second clamping groove 45, and the second clamping groove 45 is provided with a second sealing ring 46. During installation, the first end portion 41 of the first water pipe 40 extends into the pipe opening of the first connecting piece 20 and abuts against the inner wall of the pipe opening through the first sealing ring 44; and the second end portion 42 of the first water pipe 40 extends into the pipe opening of the second connecting piece 30, and the second sealing ring 46 abuts against the inner wall of the pipe opening. In this way, the sealing performance of the connection between the first water pipe 40 made of stainless steel and the first connecting piece 20 and the second connecting piece 30 is realized through the design of the sealing rings at both ends, thereby avoiding water leakage.

[0041] Further, the first clamping groove 43 is at least two, and the first sealing ring 44 is also correspondingly provided with at least two; the second clamping groove 45 is at least two, and the second sealing ring 46 is also correspondingly provided with at least two. The number of the first sealing ring 44 and the second sealing ring 46 can also be increased or reduced according to actual needs.

[0042] In the embodiment, although the first sealing ring 44 and the second sealing ring 46 on the first end portion 41 and the second end portion 42 realize the tight assembly between the stainless steel pipe and the first connecting piece 20 and the second connecting piece 30, the two ends of the stainless steel pipe cannot be limited. Since it is not suitable to make a convex position on the stainless steel pipe for limiting, in the embodiment, the first limiting step 21 is arranged in the pipe opening of the first connecting piece 20, and the second limiting step 31 is arranged in the pipe opening of the second connecting piece 30, so as to respectively block the first end portion 41 by the first limiting step 21 and block the second end portion 42 by the second limiting step 31. In this way, the two end portions of the stainless steel pipe are fixedly limited, and the stable installation of the first water pipe 40 is realized.

[0043] In the embodiment, the outer diameter of the stainless steel pipe is smaller than the outer diameter of the pipe opening of the first connecting piece 20 and the second connecting piece 30. In the embodiment, the stainless steel pipe is of equal diameter, and is not smaller at the two end portions for the purpose of being conveniently installed in the pipe opening of the first connecting piece 20 and the second connecting piece 30. Instead, the outer diameter of the entire stainless steel pipe is smaller than the outer diameter of the pipe opening of the first connecting piece 20 and the second connecting piece 30. This is because the thickness of the stainless steel pipe is relatively thin, so that, under the premise of ensuring the same water output, the outer diameter of the stainless steel pipe is smaller than that of the silica gel pipe, that is, the height of the stainless steel pipe is lower, so that the outer diameter of the faucet can also be reduced.

[0044] Preferably, in the embodiment, the first connecting piece 20 is provided with a drip-proof component 50. The drip-proof component 50 is in communication with the first water pipe 40 and the second connecting piece 30. When the faucet is in normal use, water flows out through the first water pipe 40, the drip-proof component 50 and the second connecting piece 30, and when the faucet is not in use, part of the water is stored in the first water pipe 40. To avoid the stored water from flowing out through the second connecting piece 30 and causing dripping, the water inlet 51 of the drip-proof component 50 is higher than the water outlet of the first water pipe 40. In this way, the stored water cannot flow into the drip-proof component 50 without water flow and thus cannot drip out. When in normal use, the inflowing water flow drives the stored water to flow and climb up to overflow into the water inlet of the drip-proof component 50, realizing the communication with the first connecting piece 20 and ensuring the water flow. Therefore, the drip-proof component 50 is arranged to realize the water flow when in use and block the water flow when not in use.

[0045] In the embodiment, the mounting boss 10 is provided with an axially-through first mounting hole 11, which is centrally located in the mounting boss 10 and the entire faucet pipeline. One end of the first connecting piece 20 is rotatably mounted in the first mounting hole 11 through a fastener 60. The fastener 60 is generally a mounting sleeve, which plays a fixing role on one end of the first connecting piece 20 and also plays a role of reducing the friction between the first connecting piece 20 and the mounting boss 10.

[0046] In the embodiment, the side wall of the mounting boss 10 is further provided with a radially-through second mounting hole 12, in which a second water pipe 70 is expandably mounted. In this way, two water flows are simultaneously divided through one mounting boss 10, which is convenient for users to select different water outlets according to needs. The water inlets of the first water pipe 40 and the second water pipe 70 can be connected to the same water source, which is convenient for simultaneous use at different positions, or can be connected to different water sources, such as one water pipe connected to tap water and one water pipe connected to purified water, which is convenient for daily washing or drinking.

[0047] In the embodiment, the second water pipe 70 is also a stainless steel pipe, which improves the sealing effect, reduces the water leakage points and avoids the generation of odor.

[0048] Specifically, the second water pipe 70 also adopts the same mounting structure as the first water pipe 40. The two ends of the second water pipe 70 are connected to a third connecting piece 80 and a fourth connecting piece 90, respectively. The third connecting piece 80 and the fourth connecting piece 90 are right-angle bends. One end of the fourth connecting piece 80 is rotatably arranged in the second mounting hole 12, and the other end of the fourth connecting piece 90 is connected to the second water pipe 70.

[0049] Further, the fourth connecting piece 90 can also be provided with a drip-proof component 50. The structure of the drip-proof component 50 is not limited as long as the water inlet is higher than the water outlet of the second water pipe 70.

[0050] Referring to Figure 2 , Figure 3 The embodiment of the present application also provides a faucet 1 which has the water supply structure. By using the water supply structure, water quality is improved, peculiar smell is reduced, and most importantly, water leakage and dripping are effectively avoided, and user experience of the faucet is improved.

[0051] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the foregoing embodiments of the present application have been described in detail, those skilled in the art should understand: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
