Description

Technical Field

[0001] This utility model relates to the field of connector technology for drainage systems, and in particular to a valve core connection assembly and a water valve. Background Technology

[0002] In operation, existing water valves often require precise adjustments to meet varying flow and pressure demands. To achieve this, an external adjusting shaft and handle are typically connected to the valve core, allowing operators to easily rotate the shaft to adjust the valve core's position and opening degree. However, in existing valve core and adjusting shaft connections, the two opposing components are fitted together via a shaft and keyway. While this method fulfills the functional requirements to some extent, insufficient machining precision often results in imperfect fit between the two contact surfaces.

[0003] Specifically, due to minor errors during manufacturing, uneven gaps often exist between the contact surfaces of the two connecting parts. These gaps not only reduce the tightness of the connection, leading to uneven stress and affecting the overall strength and stability, but also easily become a "hiding place" for liquid accumulation after the valve is closed. Liquid accumulation not only adversely affects the valve's sealing performance, but may also cause corrosion and rust problems in the long run, further shortening the valve's service life. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a valve core connection assembly and a water valve.

[0005] This utility model provides the following technical solution:

[0006] A valve core connection assembly is used to connect the valve core of a water valve to the handle. The valve core connection assembly includes a first connector and a second connector.

[0007] The first connector is used to connect to the handle. The first connector has a mating hole and a first snap-fit ​​part and a flow guide part on the end face of the first connector away from the handle. The second connector is used to connect to the valve core. The end face of the second connector near the first connector has a mating boss and a second snap-fit ​​part. The mating boss passes through the mating hole. The first snap-fit ​​part and the second snap-fit ​​part snap-fit ​​together. The flow guide part and the end face of the second connector near the first connector form a flow guide channel.

[0008] As a further improvement to the above technical solution, a flow guide groove is provided on the end face of the first connector near the second connector. The flow guide groove is connected to the mating hole and is used to form a flow guide section.

[0009] As a further improvement to the above technical solution, the guide channel is provided in multiple forms.

[0010] As a further improvement to the above technical solution, all of the aforementioned guide channels are arranged in parallel.

[0011] As a further improvement to the above technical solution, a through groove is provided on the side wall of the first connector, and the through groove is connected to the guide groove.

[0012] As a further improvement to the above technical solution, a snap-fit ​​groove is provided on the end face of the first connector near the second connector, and a snap-fit ​​boss corresponding to the snap-fit ​​groove is provided on the end face of the second connector near the first connector. The snap-fit ​​groove is used to form the first snap-fit ​​part, and the snap-fit ​​boss is used to form the second snap-fit ​​part.

[0013] As a further improvement to the above technical solution, at least two snap-fit ​​slots are provided.

[0014] As a further improvement to the above technical solution, the plurality of the snap-fit ​​slots are arranged in parallel to each other and penetrate through the side wall of the first connector.

[0015] As a further improvement to the above technical solution, the cross-section of the mating boss is rectangular.

[0016] As a further improvement to the above technical solution, the snap-fit ​​groove is arranged in parallel with the flow guide groove.

[0017] As a further improvement to the above technical solution, the valve core and the valve core connecting assembly are provided with a housing.

[0018] The present invention also provides a water valve, including a valve core connection assembly as described in any one of the above-mentioned embodiments.

[0019] Compared with related technologies, the beneficial effects of this utility model are:

[0020] The valve core connection assembly provided by this utility model features a highly efficient and robust connection method. Its core lies in the reliable connection between the handle and the valve core achieved through the mating cooperation of the first and second connecting parts. Specifically, the mating boss on the second connecting part is designed to pass through the pre-drilled mating hole on the first connecting part. Then, the first locking part and the corresponding second locking part on the second connecting part engage in a locking cooperation. This design not only enhances the structural strength of the connection but also significantly improves the torsional resistance between the first and second connecting parts when the operator rotates the handle to control the valve core rotation. This improvement greatly ensures the overall connection strength between the handle and the valve core, making operation smoother and more durable.

[0021] Furthermore, considering the potential issue of liquid residue in practical applications, this invention incorporates a flow guide on the first connector. This design utilizes the spatial relationship between the flow guide and the second connector, forming a flow channel. This channel ensures that any residual liquid flowing through the connection between the first snap-fit ​​part and the second connector during valve operation is quickly guided and eliminated, effectively preventing performance degradation or malfunctions caused by liquid accumulation. This design not only improves the efficiency of the water valve but also fundamentally guarantees its long-term stable operation, providing users with a more reliable and reassuring user experience.

[0035] Example 1

[0036] Combination Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a valve core connection assembly for connecting the valve core 110 of a water valve to the handle 120. The valve core connection assembly includes a first connector 200 and a second connector 300.

[0037] The first connector 200 is used to connect to the handle 120. The first connector 200 has a mating hole 210. The end face of the first connector 200 opposite to the handle 120 has a first snap-fit ​​portion and a flow guide portion. The second connector 300 is used to connect to the valve core 110. The end face of the second connector 300 near the first connector 200 has a mating boss 310 and a second snap-fit ​​portion. The mating boss 310 passes through the mating hole 210. The first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​together. The flow guide portion and the end face of the second connector 300 near the first connector 200 together form a flow guide channel.

[0038] The valve core connection assembly provided in this embodiment, during installation, firstly fixes the first connector 200 to the handle 120 and the second connector 300 to the valve core 110, and then connects the first connector 200 and the second connector 300, thereby achieving a reliable connection between the handle 120 and the valve core 110. Specifically, the mating boss 310 on the second connector 300 is used to pass into the mating hole 210 reserved in the first connector 200. Then, the first snap-fit ​​portion and the corresponding second snap-fit ​​portion on the second connector 300 can engage. This design not only enhances the structural strength of the connection but also significantly improves the torsional resistance between the first connector 200 and the second connector 300 when the operator rotates the handle 120 to control the rotation of the valve core 110. This improvement greatly ensures the overall connection strength between the handle 120 and the valve core 110, making operation smoother and more durable.

[0039] Furthermore, considering the potential issue of liquid residue in practical applications, this embodiment incorporates a flow guide on the first connector 200. This design utilizes the spatial relationship between the flow guide and the second connector 300, forming a flow channel. This flow channel ensures that any residual liquid flowing through the connection between the first snap-fit ​​part and the second connector 300 during valve core 110 operation can be quickly guided and eliminated, effectively preventing performance degradation or malfunctions caused by liquid accumulation. This design not only improves the efficiency of the water valve but also fundamentally guarantees its long-term stable operation, providing users with a more reliable and reassuring user experience.

[0040] In some specific embodiments, the first connector 200 has a guide groove 220 on its end face near the second connector 300. The guide groove 220 communicates with the mating hole 210 to form a guide portion. The presence of the guide portion is crucial for quickly removing residual liquid that may be generated during the operation of the valve core 110, ensuring a clean and reliable fit between the first connector 200 and the second connector 300.

[0041] To further optimize the flow guidance effect and improve drainage efficiency, in some embodiments, the number of flow guide channels 220 is set to multiple. The arrangement of multiple flow guide channels 220 means that more channels can be used to guide the flow of residual liquid, thereby accelerating the drainage speed and reducing the risk of liquid accumulation.

[0042] Furthermore, considering the impact of the layout of the guide channels 220 on drainage efficiency, in some embodiments, multiple guide channels 220 are arranged in parallel. The parallel arrangement of the guide channels 220 not only ensures a uniform distribution among the channels, avoiding drainage problems caused by unreasonable layout, but also makes the entire guide section more compact and orderly, improving its overall aesthetics and practicality.

[0043] In some specific embodiments, a through groove 230 is provided on the side wall of the first connector 200, and the through groove 230 is connected to the guide groove 220 to facilitate further guidance and discharge of the accumulated liquid.

[0044] In some specific embodiments, the first connector 200 has a snap-fit ​​groove 240 on its end face near the second connector 300, and the second connector 300 has a snap-fit ​​protrusion 320 corresponding to the snap-fit ​​groove 240 on its end face near the first connector 200. The snap-fit ​​protrusion 320 matches the snap-fit ​​groove 240 in shape, size, and position, so that they can be smoothly inserted into and snapped into the corresponding snap-fit ​​groove 240. The snap-fit ​​groove 240 is used to form the first snap-fit ​​part, and the snap-fit ​​protrusion 320 is used to form the second snap-fit ​​part. When the first connector 200 and the second connector 300 are assembled, the snap-fit ​​protrusion 320 can be accurately inserted into the corresponding snap-fit ​​groove 240. This snap-fit ​​connection not only makes the connection between the first connector 200 and the second connector 300 more secure and stable, but also significantly improves their torsional resistance. When the valve core 110 of the water valve is rotated and adjusted using the handle 120, it can effectively resist torsion, ensuring the normal operation and long-term use of the water valve.

[0045] In some specific embodiments, at least two snap-fit ​​slots 240 are provided; when the snap-fit ​​protrusions 320 on the second connector 300 cooperate with these snap-fit ​​slots 240, they will work together on the connection interface to form a tighter and more stable connection structure.

[0046] Furthermore, the design of the multi-slot groove 240 helps to distribute stress on the connection interface. When subjected to external forces, these slots 240 can share the stress, avoiding connection failure caused by excessive stress at a single point. Therefore, this design not only improves the strength of the connection but also enhances its reliability and durability.

[0047] In some specific embodiments, the plurality of snap-fit ​​slots 240 are arranged in parallel to each other. This parallel layout not only simplifies the processing of the snap-fit ​​slots 240 and reduces manufacturing costs, but also greatly facilitates the installation and engagement of the first connector 200 and the second connector 300.

[0048] Specifically, the parallel snap-fit ​​slots 240 ensure that the spacing, depth, and shape of each snap-fit ​​slot 240 are consistent. This allows the snap-fit ​​protrusions 320 on the second connector 300 to easily align with and insert into each snap-fit ​​slot 240 during assembly, without the need for complex adjustments and positioning. This design significantly improves assembly efficiency and accuracy, while also reducing the risk of connection failure due to improper installation.

[0049] In some specific embodiments, the snap-fit ​​groove 240 extends through the side wall of the first connector 200. This through-hole design facilitates the drainage of any accumulated liquid within the snap-fit ​​groove 240. During actual use, due to various reasons (such as ambient humidity, improper operation, etc.), some liquid may accumulate in the snap-fit ​​groove 240. If this accumulated liquid cannot be drained in time, it may affect the fit between the snap-fit ​​groove 240 and the snap-fit ​​boss 320, or even lead to connection failure. The through-hole design of the snap-fit ​​groove 240 ensures that the accumulated liquid can be smoothly drained through the opening on the side wall, thus avoiding this problem.

[0050] In some specific embodiments, the mating boss 310 has a rectangular cross-section. This rectangular cross-section design provides a more defined positioning reference for the mating boss 310. When the second connector 300 is assembled with the first connector 200, the mating boss 310 can be precisely inserted into the corresponding mating groove in the first connector 200, thereby effectively limiting the relative position between the first connector 200 and the second connector 300. This limitation not only ensures the accuracy of their position after assembly but also greatly improves the stability of the connection.

[0051] Furthermore, the rectangular cross-sectional design helps to increase the contact area between the mating boss 310 and the mating groove. Compared to other shapes, a rectangle provides a more uniform and wider contact surface, thereby increasing the friction and shear resistance of the connection. This means that when subjected to external forces, the mating boss 310 is less likely to dislodge from the mating groove, further improving the reliability and durability of the connection.

[0052] More importantly, the rectangular cross-section design facilitates machining and manufacturing. During production, standard rectangular cutting tools or molds can be used to machine the mating boss 310 and the mating groove, thereby reducing manufacturing costs and improving production efficiency.

[0053] In some specific embodiments, the snap-fit ​​groove 240 and the guide groove 220 are arranged parallel to each other. Firstly, from the perspective of processing difficulty, the parallel arrangement of the snap-fit ​​groove 240 and the guide groove 220 greatly simplifies the production process. During manufacturing, the same processing tools and equipment can be used to process the snap-fit ​​groove 240 and the guide groove 220 along the same direction, thereby avoiding additional operations and adjustments caused by changes in angle. This not only reduces processing difficulty but also improves production efficiency, making the entire production process smoother and more efficient.

[0054] Secondly, the parallel arrangement of the snap-fit ​​groove 240 and the flow guide groove 220 also helps to improve the overall performance of the product. The snap-fit ​​groove 240, as a fixing structure between the connectors, is crucial for stability and reliability. The flow guide groove 220, on the other hand, guides the flow of fluid between the connectors, ensuring smooth and efficient fluid flow. When both are arranged in parallel, they work together on the connector, ensuring both the stability of the connection and the smooth flow of fluid, thereby improving the overall performance and reliability of the product.

[0055] like Figure 1 As shown, in some specific embodiments, the valve core 110 and the valve core connecting assembly are provided with a housing 130 to provide protection for the valve core 110 and the valve core connecting assembly.
