Description

Technical Field

[0001] This application pertains to kitchen and bathroom valves and accessories, specifically including kitchen and bathroom valves and accessories with replaceable water passage components. Background Technology

[0002] Some kitchen and bathroom valves, such as faucets, have internal water flow structures to ensure that the water flow path is not contaminated. The replaceability of these water flow structures also reduces the cost of valve reuse. However, conventional water flow structures often use a split design, which increases the number of connection points between components, making sealing more difficult and reducing safe operating life. Furthermore, damage to the seal can easily cause components to detach, making replacement difficult. Utility Model Content

[0005] In some embodiments, the distal engagement portion is the distal flange of the distal end portion; the first sealing mating surface is the entire axial outer surface of the distal flange, and an annular protrusion is provided on the first sealing mating surface.

[0006] In some embodiments, the annular water passage is formed by thinning a portion of the sidewall; the middle portion of the sidewall is provided with a sealing fit structure for the valve core, and the upper portion of the sidewall is provided with an internal thread structure for engaging with the upper locking nut, thereby locking the valve core in the inner cavity by the upper locking nut; the base includes a water inlet corresponding to the water inlet of the valve core, and the water inlet is sealed to the water inlet of the valve core.

[0007] In some embodiments, the lateral portion is a horizontal structure; or the lateral portion is an arched structure, thereby allowing the annular water passage and the water outlet to be positioned at substantially the same height.

[0008] Some other embodiments of this application propose a faucet with an integrated water-passing structure, comprising: a handle, a decorative ring, an upper locking nut, a valve core, an upper cover plate, any one of the above-mentioned water-passing structures, a faucet body, and a spout; wherein, the faucet body includes a column portion and a support portion angled to the column portion; wherein, the column portion includes a first accommodating space arranged in the direction of the column portion, and the support portion includes a second accommodating space arranged in the direction of the support portion, and the second accommodating space communicates with the first accommodating space; the first accommodating space is used to accommodate a longitudinal portion of the water-passing structure and a valve core installed in the longitudinal portion, and the second accommodating space is used to accommodate a transverse portion of the water-passing structure; the water-passing structure is fixed in the first accommodating space by a base, and the first accommodating space is defined by a support plate provided in the column portion; the transverse portion is a tubular body located in the second accommodating space, and the transverse portion has a configuration conforming to the shape of the second accommodating space.

[0009] In some embodiments, a lower adapter ring is provided at the bottom of the column portion, and the lower adapter ring is threaded onto the outer surface of the bottom of the column portion, thereby fixing the faucet to the countertop.

[0010] In some embodiments, the tray has a perforated structure that allows the water inlet to pass through, and a first positioning structure for positioning the water passage structure; the water passage structure includes a second positioning structure corresponding to the first positioning structure for limiting the rotation of the longitudinal portion; the tray is also provided with screw holes to allow the base to be fixed to the tray by screws.

[0011] The advantages of this utility model are as follows: on the one hand, the integrated water-passing structure design can reduce the number of sealing interfaces, thereby reducing the possibility of sealing failure; on the other hand, due to the integrated structure, no components will fall off when the water-passing structure is replaced as a whole, making the replacement process more convenient.

[0027] like Figure 1 , Figure 2 As shown, the faucet with an integrated water-passing structure includes a handle 1, a decorative ring 2, an upper locking nut 3, a valve core 4, an upper cover 5, a water-passing structure 6, a faucet body 7, a spout 8, and a lower adapter ring 9. The faucet body 7 includes a column portion 71 and a support portion 72 angled to the column portion 71. The column portion 71 includes a first accommodating space 711 aligned with its orientation, for example, longitudinally. The support portion 72 includes a second accommodating space 721 aligned with its orientation, for example, horizontally, and the second accommodating space 721 communicates with the first accommodating space 711. The first accommodating space 711 accommodates the longitudinal portion 61 of the water-passing structure 6 and the valve core 4 installed within it. The second accommodating space 72 accommodates the transverse portion 62 of the water-passing structure 6.

[0028] like Figure 4 As shown, the valve core 4 is a side-outlet valve core. For example, the valve core includes a main body 41 and an operating part 42. The operating part 42 is connected to a handle 1. The main body 41 has a valve core inlet on the ground, such as a cold water inlet 411 and a hot water inlet 412. The valve core outlet 413 is located on the side of the valve core, for example, on the side of the bottom of the main body 41. The operating part 42 cooperates with the main body 41 to operate the opening and closing of the valve core and / or adjust the water temperature. Inside the valve core 4, the cold water inlet 411 is connected to a cold water channel, and the hot water inlet 412 is connected to a hot water channel. The cold water channel and the hot water channel send cold water and hot water into the mixing chamber respectively for mixing, and then send them to the valve core outlet 413 through the outlet channel.

[0029] As described above, the water-passing structure 6 includes a longitudinal portion 61 and a transverse portion 62 communicating with the longitudinal portion. The longitudinal portion 61 is as follows... Figure 4 , Figure 5 As shown, for example, it is formed by a cylindrical sidewall 611 and a base 612. The inner surface of the cylindrical sidewall 611 defines an inner cavity 613, which is configured to provide an annular water passage 6131 corresponding to the position of the valve core outlet 413. The annular water passage communicates with the transverse portion 62. The annular water passage 6131 can be formed by thinning a portion of the thickness of the sidewall 611, for example, thinning the thickness of the lower portion 6113 of the sidewall.

[0030] The middle portion 6112 of the sidewall 611 can provide a sealing fit structure with the valve core 4, for example, by forming a sealing fit with the outer surface of the valve core 4 through a sealing ring 43. The upper portion 6111 of the sidewall 611 can provide an internal thread structure that mates with the upper locking nut 3, so that the valve core 4 can be locked in the inner cavity 613 by the upper locking nut 3. The upper part of the upper locking nut 3 can be matched, for example, by snap-fitting or threaded connection to a decorative ring 2.

[0031] like Figure 6 , Figure 7 As shown, the base 612 includes a water inlet 6121 corresponding to the valve core inlet, such as the cold water inlet 411 and the hot water inlet 412, and the water inlet 612 is sealed to the valve core inlet. Figure 3 , Figure 8 As shown, the water-passing structure 6 is fixed within the first accommodating space 711 by the base 612. The first accommodating space 711 can be defined by a support plate 712 provided within the column portion 71. The support plate 712 may have, for example, a hollow structure that allows the water inlet opening to pass through, and a first positioning structure 7121 for positioning the water-passing structure 6, such as two positioning holes. Correspondingly, the water-passing structure 6 includes, for example, a second positioning structure 6122 corresponding to the first positioning structure 7121, such as two positioning posts matching the two positioning holes, for limiting the rotation of the longitudinal portion 61. The support plate 712 may also be provided with screw holes 7122 to allow the base 612 to be fixed to the support plate 712 by screws 10.

[0032] like Figure 3As shown, the lower part of the first accommodating space 711 of the column portion 71 may include a third cavity 713, the height of which can determine the overall height of the column portion. In the following embodiments, the height of the spout can also be determined. In this embodiment, a lower adapter ring 9 may be provided at the bottom of the column portion 71. For example, the lower adapter ring 9 is threaded onto the outer surface of the bottom of the column portion 71, thereby fixing the faucet to the countertop.

[0033] The transverse portion 62 of the water passage structure 6 is a tubular body located within the second accommodating space 721. The transverse portion 62 can be configured to conform to the shape of the second accommodating space 721. For example, when the second accommodating space 721 is a horizontal cavity, the transverse portion 62 can be a horizontal structure, such as a horizontal pipe. Alternatively, the transverse portion 62 can be any structure within the second accommodating space 721. For example, the transverse portion 62 can be an arched structure, such as an arched pipe, thereby allowing the annular water passage 6131 and the water outlet 8 to be positioned at substantially the same height. The arched design of the transverse portion 62 is particularly advantageous. The supporting portion 72 is an open structure at the top, requiring the upper cover plate 5 to completely cover the transverse portion 62. Therefore, the supporting portion 72 includes a snap-fit ​​structure 723 that engages with the end of the upper cover plate 5, and a support structure 724 that supports the upper cover plate 5.

[0034] In this embodiment, the decorative ring 2 matching the upper part of the upper locking nut 3 can also be configured to be large enough to press down on the upper cover plate 5 to fix the upper cover plate 5.

[0035] As shown in the figure, the proximal end of the transverse portion 62 is connected to the longitudinal portion 61, and the distal end of the transverse portion 62 is fixed to the support portion 72. For example, the distal end of the transverse portion 62 may have a radially enlarged portion forming a distal locking portion 621, and the interior of the support portion 72 may have a matching locking groove 725. During installation, the distal locking portion 621 extends into the locking groove 725, thereby fixing the distal end of the transverse portion 62. Figure 5 , Figure 6 As shown, the distal engaging portion 621 is the distal flange of the distal end portion. Similarly, as... Figure 5 , Figure 6 As shown, a first sealing mating surface 622 may be provided at the distal end, the first sealing mating surface 622 being the integral axial outer surface of the distal flange, the mating surface being, for example, an annular protrusion.

[0036] The supporting portion 72 can provide a first fixing structure 722 that mates with the water outlet 8. For example, the supporting portion 72 can provide a threaded opening. The water outlet 8 can include a second fixing structure 811 corresponding to the first fixing structure 722, such as a threaded structure corresponding to the threaded opening, thereby fixing it to the supporting portion 72. The inner end face of the water outlet 8 can provide a second sealing mating surface 812 that matches the first sealing mating surface 622, so that after the second fixing structure 811 of the first fixing structure 722 is connected, the first sealing mating surface 622 and the second sealing mating surface 812 cooperate to form an integral sealing structure.

[0037] In this way, a complete water outlet path is formed, that is, the warm water in the annular water passage 6131 is supplied to the outside through the horizontal part 62 from the water outlet 8.

[0038] The integrated water-passing structure 6 provided in the embodiments of this application integrates the traditional valve core mounting seat, water-passing pipe, and water outlet interface into one component, which can reduce connection interfaces, simplify the structure, and facilitate installation. The water-passing structure can be integrally molded from materials such as PE, which has the characteristics of being healthy and environmentally friendly and easy to replace. The upper cover plate 5, faucet body 7, etc. can be made of materials such as stainless steel. Each sealing structure and sealing ring can be made of rubber, silicone, or polymer materials.

[0039] The faucet assembly method of this application can be as follows: the water passage structure 6 is fixed inside the faucet body 7, including positioning the horizontal part 62 in the support part 72, positioning the vertical part 61 in the column part 71, fitting the valve core 4 into the inner cavity of the vertical part 61, fixing the valve core in the inner cavity with the upper locking nut 3, positioning the upper cover plate 5 in the support part, and then fixing the water outlet 8 in the support part 72 to complete the assembly.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
