[0041] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0042] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0043] Reference Figures 1 to 5 As shown in the figure, this application provides a valve seat pipeline assembly, including a valve core seat 100, an inlet pipe 200, an outlet pipe 300, and a snap-fit ​​component 400.

[0044] The valve core seat 100 has a valve seat cavity 110 and an inlet hole 120 and an outlet hole 130 communicating with the valve seat cavity 110. One end of the inlet pipe 200 is inserted into the valve seat cavity 110 through the inlet hole 120, and one end of the inlet pipe 200 has a first snap-fit ​​part 210. One end of the outlet pipe 300 is inserted into the valve seat cavity 110 through the outlet hole 130, and one end of the outlet pipe 300 has a second snap-fit ​​part 310.

[0045] The side wall of the valve core seat 100 is provided with a mounting groove 140 that communicates with the valve seat cavity 110. The snap-fit ​​member 400 is provided in the mounting groove 140 and snaps into the first snap-fit ​​part 210 and the second snap-fit ​​part 310 respectively.

[0046] In a specific implementation, the inner cavity of the valve core seat 100 is formed as a valve seat cavity 110, and the bottom end of the valve core seat 100 can be provided with a water inlet hole 120 and a water outlet hole 130 for supplying water into the valve seat cavity 110 or allowing water in the valve seat cavity 110 to flow out. The valve core seat 100 can specifically be a cylindrical structure, and the outer wall surface of the cylindrical structure can be set as a grid-like reinforcing structure to improve the structural strength of the valve core seat 100. For example, the valve core seat 100 can be made of plastic to reduce costs.

[0047] Furthermore, to fix the inlet pipe 200 and outlet pipe 300 to the valve core seat 100, an installation groove 140 is formed on the side wall of the valve core seat 100, and the installation groove 140 communicates with the valve seat cavity 110. A first snap-fit ​​part 210 and a second snap-fit ​​part 310 are respectively provided at the end of the inlet pipe 200 extending into the valve seat cavity 110 and the end of the outlet pipe 300 extending into the valve seat cavity 110. The snap-fit ​​part 400 is snapped into the first snap-fit ​​part 210 and the second snap-fit ​​part 310 located in the valve seat cavity 110 through the installation groove 140, thereby reliably fixing the inlet pipe 200 and outlet pipe 300 to the valve core seat 100. Moreover, the method of directly using the snap-fit ​​part 400 to snap-fit ​​the first snap-fit ​​part 210 and the second snap-fit ​​part 310 is simpler and faster, with fewer parts, thus saving costs.

[0048] In practice, to facilitate the snap-fit ​​connection, the first snap-fit ​​part 210 and the second snap-fit ​​part 310 can be set at the same height along the axial direction of the water inlet pipe 200, that is, they are located at the same height position, so that the snap-fit ​​member 400 can simultaneously snap-fit ​​with the first snap-fit ​​part 210 and the second snap-fit ​​part 310.

[0049] In this embodiment, the inlet pipe 200 and the outlet pipe 300 are arranged in parallel, and the inlet hole 120 and the outlet hole 130 are located on the same side of the valve core seat 100, for example, both are set on the bottom surface of the valve core seat 100. This makes the structure more regular and the layout more reasonable.

[0050] The valve seat piping assembly of this embodiment includes a valve core seat 100, an inlet pipe 200, an outlet pipe 300, and a snap-fit ​​component 400. The valve core seat 100 has a valve seat cavity 110 and an inlet hole 120 and an outlet hole 130 communicating with the valve seat cavity 110. One end of the inlet pipe 200 is inserted into the valve seat cavity 110 through the inlet hole 120, and one end of the inlet pipe 200 has a first snap-fit ​​part 210. One end of the outlet pipe 300 is inserted into the valve seat cavity 110 through the outlet hole 130, and one end of the outlet pipe 300 has a second snap-fit ​​part 310. The valve core seat 100 has a mounting groove 140 that communicates with the valve seat cavity 110 on its side wall. The snap-fit ​​part 400 is located in the mounting groove 140 and snaps into the first snap-fit ​​part 210 and the second snap-fit ​​part 310 respectively, thereby realizing the snap-fit ​​connection between the water inlet pipe 200, the water outlet pipe 300 and the valve core seat 100. This assembly method is simple and quick, and can save time and reduce production costs.

[0051] Reference Figures 3 to 5As shown, in some embodiments, the first snap-fit ​​part 210 is a first annular groove extending circumferentially along the water inlet pipe 200, and part of the snap-fit ​​member 400 is snapped into the first annular groove, that is, part of the snap-fit ​​member 400 is snapped into the first annular groove, thereby realizing a reliable connection between the water inlet pipe 200 and the valve core seat 100.

[0052] Alternatively, in other implementations, the first snap-fit ​​part 210 can also be a snap ring, with the snap-fit ​​part 400 snapped inside the snap ring, thereby achieving a reliable connection between the water inlet pipe 200 and the valve core seat 100.

[0053] Reference Figures 3 to 5 As shown, in some embodiments, the second snap-fit ​​part 310 is a second annular groove extending circumferentially along the water outlet pipe 300, and part of the snap-fit ​​member 400 is snapped into the second annular groove, that is, part of the snap-fit ​​member 400 is snapped into the second annular groove, thereby realizing a reliable connection between the water outlet pipe 300 and the valve core seat 100.

[0054] Alternatively, in other implementations, the second snap-fit ​​part 310 can also be a snap ring, with the snap-fit ​​part 400 snapped inside the snap ring, thereby achieving a reliable connection between the water outlet pipe 300 and the valve core seat 100.

[0055] Reference Figure 4 As shown, in some embodiments, the snap-fit ​​member 400 includes a snap-fit ​​body 410 and at least three snap-fit ​​arms 420 disposed on one side of the snap-fit ​​body 410. The at least three snap-fit ​​arms 420 are spaced apart along the direction from the water inlet hole 120 to the water outlet hole 130. The at least three snap-fit ​​arms 420 extend into the valve seat cavity 110 and engage with the corresponding first snap-fit ​​mating part 210 and / or second snap-fit ​​mating part 310.

[0056] In practice, at least three snap-fit ​​arms 420 are connected to the side of the snap-fit ​​body 410 near the mounting groove 140, and all snap-fit ​​arms 420 extend into the valve seat cavity 110 and snap-fit ​​with the corresponding first snap-fit ​​mating part 210 or second snap-fit ​​mating part 310.

[0057] For example, when the card arm 420 is set as follows Figure 4 As shown in the diagram, at this time, one of the two outer locking arms 420 engages with the corresponding one of the first locking engagement part 210 and the second locking engagement part 310, and the other of the two locking arms 420 engages with the corresponding other one of the first locking engagement part 210 and the second locking engagement part 310. The middle locking arm 420 engages with both the first locking engagement part 210 and the second locking engagement part 310, thereby reliably locking and fixing the inlet pipe 200 and the outlet pipe 300 onto the valve core seat 100 using the three locking arms 420.

[0058] For example, when the first snap-fit ​​part 210 is the first annular groove and the second snap-fit ​​part 310 is the second annular groove, one of the two outer snap-fit ​​arms 420 snaps onto the side of the first annular groove away from the second annular groove, and the other of the two snap-fit ​​arms 420 snaps onto the side of the second annular groove away from the first annular groove. The middle snap-fit ​​arm 420 snaps onto the side of the first annular groove near the second annular groove, and also snaps onto the side of the second annular groove near the first annular groove. That is, the middle snap-fit ​​arm 420 snaps onto the first annular groove and the second annular groove respectively, so as to realize the sharing of snap-fit ​​arms 420, thereby saving the number of snap-fit ​​arms 420, and thus realizing the reliable snap-fit ​​fixing of the water inlet pipe 200 and the water outlet pipe 300 onto the valve core seat 100 by using three snap-fit ​​arms 420.

[0059] Alternatively, in other implementations, four snap-fit ​​arms 420 can be set, in which two adjacent snap-fit ​​arms 420 are snapped onto opposite sides of the first annular groove, and the other two adjacent snap-fit ​​arms 420 are snapped onto opposite sides of the second annular groove, thereby achieving snap-fit ​​fixing of the inlet pipe 200 and the outlet pipe 300 to the valve core seat 100.

[0060] Reference Figure 3 and Figure 4 As shown, in some embodiments, the mounting groove 140 includes an arc-shaped main groove 141 extending circumferentially along the valve core seat 100 and at least three through grooves 142. The through grooves 142 are respectively connected to the arc-shaped main groove 141 and the valve seat cavity 110. The snap-fit ​​body 410 is disposed in the arc-shaped main groove 141. At least three snap-fit ​​arms 420 extend into the valve seat cavity 110 through the corresponding through grooves 142, so that the snap-fit ​​arms 420 can be inserted into the valve seat cavity 110 through the through grooves 142 and then snap-fit ​​and fixed with the corresponding water inlet pipe 200 and water outlet pipe 300.

[0061] Reference Figure 3 and Figure 4 As shown, in some embodiments, the outer contour shape of the snap-fit ​​body 410 is adapted to the contour shape of the arc-shaped main groove 141 so as to facilitate the placement of the snap-fit ​​body 410 without wasting the inner cavity space of the arc-shaped main groove 141.

[0062] Reference Figures 1 to 5 As shown, in some embodiments, the outer surface of the snap-fit ​​body 410 is flush with the outer peripheral surface of the valve core seat 100, so that after the entire assembly operation is completed, there will be no protrusions or depressions on the outer wall surface of the valve core seat 100, making the appearance of the valve core seat 100 more aesthetically pleasing. At the same time, it can avoid the problem of assembly interference to other structures if there are protrusions, and it can also avoid the problem of easy accumulation of debris if there are depressions.

[0063] For example, the snap-fit ​​body 410 and at least three snap-fit ​​arms 420 are integrally formed to save manufacturing steps and improve the structural strength of the entire snap-fit ​​400.

[0064] For example, when the card arm 420 is set to three, the card connector 400 as a whole can be arranged as follows: Figure 4 The “E” shaped structure shown.

[0065] Reference Figure 4 As shown, in some embodiments, there are three snap-fit ​​arms 420, and the size of the middle snap-fit ​​arm 420 in the direction of arrangement of snap-fit ​​arms 420 is larger than the size of the snap-fit ​​arms 420 on both sides in the direction of arrangement of snap-fit ​​arms 420.

[0066] In specific implementation, since the middle snap-fit ​​arm 420 is a shared snap-fit ​​arm 420 when there are three snap-fit ​​arms 420, that is, it snaps into the first annular groove and the second annular groove at the same time, the size of the middle snap-fit ​​arm 420 can be set to be larger so that it has enough size to snap into the first annular groove and the second annular groove respectively.

[0067] For example, refer to Figure 4 As shown, the two side snap-fit ​​arms 420 are symmetrically arranged with respect to the central axis of the middle snap-fit ​​arm 420, so as to make the structure more regular and facilitate processing and manufacturing.

[0068] Reference Figure 4 As shown, in some embodiments, the connection between the snap-fit ​​arms 420 on both sides and the snap-fit ​​body 410 is smoothly transitioned, so as to adapt to the arc-shaped main groove 141 while avoiding stress concentration at the connection, thereby improving service life.

[0069] Reference Figure 4 As shown, in some embodiments, a guide structure 430 is provided on the end face of the snap-fit ​​arm 420 near the mounting groove 140 along the direction in which the snap-fit ​​400 is inserted into the mounting groove 140, so that the snap-fit ​​400 can be quickly and accurately inserted into the mounting groove 140 to improve assembly efficiency.

[0070] Reference Figure 4 As shown, in some embodiments, the guide structure 430 includes at least one guide surface 431. The guide surface 431 is disposed on the side of the snap-fit ​​arm 420 facing the corresponding first snap-fit ​​mating part 210 or the second snap-fit ​​mating part 310. In the direction along which the snap-fit ​​member 400 is inserted into the mounting groove 140, the guide surface 431 is inclined in a direction away from the corresponding first snap-fit ​​mating part 210 or the second snap-fit ​​mating part 310 to play a guiding role and prevent the insertion from being skewed, which would lead to poor insertion accuracy.

[0071] For example, the latching arm 420 that mates with the first latching engagement part 210 is provided with a guide surface 431, which is inclined in a direction away from the first latching engagement part 210 to facilitate insertion guidance. Similarly, the latching arm 420 that mates with the second latching engagement part 310 is provided with a guide surface 431, which is inclined in a direction away from the second latching engagement part 310 to facilitate insertion guidance.

[0072] For example, when there are three snap-fit ​​arms 420, a guide surface 431 can be provided on the two outer snap-fit ​​arms 420. Two symmetrical guide surfaces 431 can be provided on the middle snap-fit ​​arm 420.

[0073] Reference Figure 6 and Figure 7 As shown, this embodiment provides a basin faucet, including an assembly pipe 500, a threaded connector 600, and a valve seat pipeline assembly.

[0074] The assembly tube 500 is sleeved on the outer periphery of the valve core seat 100; the assembly tube 500 includes at least a smooth section 510 and a threaded section 520. The smooth section 510 is used to pass through the mounting hole of the basin 700. The outer wall of the threaded section 520 is provided with a connecting thread 521. The threaded connector 600 engages with the connecting thread 521, and the threaded connector 600 is provided with a fastening hole and a fastener 610 that mates with the fastening hole.

[0075] Along the thickness direction of the basin 700, the length of the smooth section 510 is greater than the thickness of the basin 700. A support seat 800 is provided on the side of the threaded connector 600 facing the bottom surface of the basin 700. The support seat 800 abuts against the basin 700 and the fastener 610 respectively.

[0076] The specific structure and implementation principle of the valve seat pipeline assembly in this embodiment are the same as those of the valve seat pipeline assembly provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the description of the above embodiments.

[0077] In practice, the assembly tube 500 is sleeved on the outer periphery of the valve core seat 100, and the assembly tube 500 can be set into two sections, namely the smooth section 510 and the threaded section 520. The reason for setting the smooth section 510 is that due to the limitations of the mounting hole size of the basin 700 and the size of the valve core seat 100, the smooth section 510 is set to ensure installation. The purpose of setting the threaded section 520 is to engage with the threaded connector 600 to adjust the position of the threaded connector 600 relative to the basin 700.

[0078] For example, when the thickness of the basin 700 is greater than the length of the smooth section 510, the fastener 610 set on the threaded connector 600 can abut against the basin 700 to achieve support and fixation of the basin 700.

[0079] For example, when the thickness of the basin 700 is less than the length of the smooth section 510, a portion of the smooth section 510 is exposed, causing the fastener 610 on the threaded connector 600 to be unable to abut against the basin 700, thus failing to provide support for the basin 700. In this case, an additional support base 800 can be provided between the threaded connector 600 and the bottom surface of the basin 700. The fastener 610 abuts against the bottom surface of the support base 800, and the top surface of the support base 800 abuts against the bottom surface of the basin 700, thereby ultimately achieving support for the basin 700.

[0080] In other words, the basin faucet in this embodiment can select the support base 800 according to the actual thickness of the light section 510 and the basin 700. The support base 800 and the threaded connector 600 are separate structures, that is, there is no mechanical fixed connection between the two. Therefore, it can be selected and used according to the actual situation. Moreover, the whole structure is simple, the production cost is low, and the reliability is also good.

[0081] Reference Figure 6 As shown, in some embodiments, the support base 800 includes a support sleeve 810, which is sleeved on the assembly tube 500. The two ends of the support sleeve 810 in the axial direction are respectively provided with abutting flanges 820 that abut against the basin 700 and the fastener 610, so as to realize the abutting fit between the support sleeve 810 and the basin 700 and the fastener 610.

[0082] In practice, the outer diameter of the abutment flange 820 is larger than the outer diameter of the mounting hole. This ensures a reliable abutment fit between the abutment flange 820 and the basin 700, and prevents the abutment flange 820 from penetrating into the mounting hole.

[0083] In some embodiments, the support sleeve 810 and the abutment flange 820 are integrally formed to save manufacturing steps while improving the structural strength of the entire support base 800.

[0084] For example, the support 800 is a plastic support 800, which can reduce material costs.

[0085] For example, the threaded connector 600 is a connecting nut, which is a universal part that can be directly selected according to actual needs.

[0086] For example, the fastening hole is a threaded hole, and the fastener 610 is a threaded fastener 610 that engages with the threaded hole, so that the threaded fastener 610 is screwed into the support 800 for abutment engagement through the engagement of the threaded fastener 610 with the threaded hole.

[0087] Alternatively, in other implementations, the fastening hole can be a smooth hole, and the fastener 610 can be a fastening pin.

[0088] Reference Figure 6 and Figure 7 As shown, in some embodiments, there are at least two fasteners 610, which are spaced apart circumferentially along the threaded connector 600. There are at least two fastening holes, and each of the at least two fastening holes corresponds to one of the at least two fasteners 610. The at least two fasteners 610 abut against the support base 800 to improve the balanced circumferential support of the support base 800, thereby improving the balanced and stable support of the basin 700.

[0089] In a specific implementation, the basin faucet also includes a handle assembly 900, which includes a handle 910 and a handle seat 920. The handle 910 is disposed on the handle seat 920, and the handle seat 920 is located on the side of the basin 700 away from the support seat 800 and is connected to the assembly tube 500, so as to reliably clamp and fix the basin 700 between the handle seat 920 and the support seat 800, thereby achieving reliable assembly and fixation of the basin 700.

[0090] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0091] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
