Description

Technical Field

[0001] This utility model relates to the field of bathroom structure technology, specifically to a valve core with a pull-out hole and a water outlet device. Background Technology

[0002] Traditional valve core structures have several shortcomings: First, conventional valve cores require an additional valve core seat to install the inlet and outlet pipes, which not only increases the number of parts and production costs but also makes the overall structure more complex. Second, in kitchen faucets with pull-out functions, to avoid interference with the pull-out pipe, the valve core is usually positioned off-center from the pull-out path. This design increases the width of the faucet body, making the overall size of the water outlet device too large, affecting aesthetics and taking up space. Although existing technologies such as CN217177514U disclose valve core structures with through channels, the problem of direct pipe installation is still not solved, and pipe connections still rely on valve core seats. These structural defects lead to cumbersome installation procedures, difficult maintenance, and make it difficult to achieve a compact design. Utility Model Content

[0003] This utility model discloses a valve core with a pull-out hole, which aims to solve the problems mentioned above.

[0004] The present invention adopts the following solution: A valve core with a pull-out hole includes: a control body with a pull-out channel, a housing sleeved on the outside of the control body, and a mounting base connected to the lower part of the housing. The mounting base is located below the control body and has an inlet mounting column and an outlet mounting column communicating with the water inlet channel and the water outlet channel of the control body. The inlet mounting column is adapted to directly install an inlet pipe; the outlet mounting column is adapted to directly install one end of an outlet pipe; and the other end of the outlet pipe is adapted to pass through the pull-out channel for free pull-out.

[0005] Furthermore, the mounting base is detachably mounted on the underside of the housing.

[0006] Furthermore, the mounting base is provided with a plurality of snap-fit ​​grooves on its periphery, and snap-fit ​​protrusions are provided in the snap-fit ​​grooves; a connecting block matching the snap-fit ​​grooves is provided on the lower part of the housing, and the connecting block is provided with snap-fit ​​holes to match the snap-fit ​​protrusions.

[0007] Furthermore, the inlet and outlet mounting columns are provided with internal threads to facilitate connection with the external threads of the inlet and outlet pipes.

[0008] Furthermore, the inlet and outlet mounting columns are provided with metal mounting rings having internal threads, and the metal mounting rings and the mounting base body are formed by a secondary injection molding process.

[0009] Furthermore, the outer side of the metal mounting ring is provided with several annular grooves to improve the connection strength with the mounting base body.

[0010] Furthermore, the control body includes an operating component, a movable piece connected to the operating component, and a fixed piece disposed below the movable piece. The fixed piece has an inlet channel and an outlet channel that connect the inlet mounting column and the outlet mounting column. The movable piece has a connecting groove on the side facing the fixed piece to control the opening and closing of the inlet channel and the outlet channel.

[0011] Furthermore, the fixed plate, moving plate, operating member, and mounting base are formed with through holes to form the pull-out channel in the axial direction.

[0012] Furthermore, there are two water inlet mounting columns, and the water outlet mounting column is located on the symmetrical line of the two water inlet mounting columns and on the other side of the pull-out channel.

[0013] The present invention also provides a water outlet device, including the valve core with a pull-out hole.

[0014] Beneficial effects: This solution directly connects the inlet and outlet pipes via a mounting base and utilizes a pull-out channel to allow the outlet pipe to be freely pulled out. This solves the problem of complex structure caused by the traditional valve core relying on the valve core seat. It has the advantages of compact structure, convenient installation, and the ability to allow the outlet pipe to be freely pulled out. At the same time, the outlet pipe can be directly led out of the pull-out channel, making the structure even more compact. Attached Figure Description

[0016] Combination Figures 1 to 4As shown, this embodiment provides a water outlet device, including a valve core with a pull-out hole. The valve core with the pull-out hole includes: a control body 1 with a pull-out channel 4, a housing 2 sleeved on the outside of the control body 1, and a mounting base 3 connected to the lower part of the housing 2. The mounting base 3 is located below the control body 1 and has an inlet mounting column 31 and an outlet mounting column 32 connecting the inlet channel and the outlet channel of the control body 1. The inlet mounting column 31 is suitable for directly installing an inlet pipe; the outlet mounting column 32 is suitable for directly installing one end of an outlet pipe; the other end of the outlet pipe is suitable for passing through the pull-out channel 4 for free pulling. It should be noted that the outlet pipe can be a single piece or assembled from two flexible hoses.

[0017] The mounting base 3 refers to the connecting component located at the bottom of the housing 2 and spatially engaging with the control body 1. It can be manufactured using injection molding, and its internal channel is coaxially aligned with the fluid channel of the control body 1. The inlet mounting column 31 and outlet mounting column 32 are columnar connecting structures mounted on the mounting base 3. They can be designed as cylinders with internal threads for direct screwing into standard-sized inlet pipe connectors. The pull-out channel 4 is a tubular cavity extending axially through the control body 1. It can be formed by creating coaxial through holes in the moving plate 12, the fixed plate 11, and the operating component 13, allowing the outlet pipe to move axially within the channel to form a pull-out tube.

[0018] Mounting base 3 is fixed to the bottom of housing 2 via a bottom connecting structure. Its inlet mounting post 31 and outlet mounting post 32 form a sealed connection with the inlet and outlet channels within the control body 1, respectively. The inlet pipe is directly screwed into the inlet mounting post 31 for connection, while one end of the outlet pipe is fixed to the outlet mounting post 32, and the other end extends upward through the pull-out channel 4. When the user performs a pull-out operation, the outlet pipe can freely extend and retract along the pull-out channel 4. Since sufficient movement space is reserved inside the valve core, no additional clearance structure is required. This integrated design allows the connection between the inlet and outlet pipes to be directly integrated into the valve core body, eliminating the need for a traditional valve core seat structure. This solution reduces the number of parts and assembly steps by integrating mounting base 3 with housing 2. The through-type pull-out channel 4 achieves coaxial arrangement of the pipes and valve core, effectively compressing the lateral dimensions.

[0019] Continue to combine Figures 1 to 4As shown, in this embodiment, the mounting base 3 is detachably mounted below the housing 2. Detachability means that the mounting base 3 and the housing 2 are separably fixed via a connection structure, which can be achieved through snap-fit, threaded connection, or plug-in connection. Specifically, the mounting base 3 has several snap-fit ​​grooves 33 on its periphery, and snap-fit ​​protrusions 34 are provided within the snap-fit ​​grooves 33. A connecting block 21 matching the snap-fit ​​grooves 33 is provided below the housing 2, and the connecting block 21 has snap-fit ​​holes 22 to match the snap-fit ​​protrusions 34. The snap-fit ​​groove 33 refers to a recessed structure formed on the periphery of the mounting base 3, which can be a rectangular groove, used to accommodate the connecting block 21 below the housing 2. The snap-fit ​​protrusion 34 refers to a protruding structure provided inside the snap-fit ​​groove 33, used to engage and fix with the snap-fit ​​holes 22 on the connecting block 21. The mounting base 3 achieves initial positioning with the housing 2 through the matching of the snap-fit ​​groove 33 and the connecting block 21. Then, a pressing action causes the snap-fit ​​protrusion 34 to engage with the snap-fit ​​hole 22, thus completing the detachable connection between the mounting base 3 and the housing 2. The engagement of the snap-fit ​​protrusion 34 and the snap-fit ​​hole 22 forms a mechanical lock, ensuring the mounting base 3 remains stable in both the axial and radial directions. During disassembly, applying a reverse external force causes the snap-fit ​​protrusion 34 to disengage from the snap-fit ​​hole 22, separating the mounting base 3 from the housing 2. This snap-fit ​​structure enables quick installation and disassembly without the need for additional tools, while avoiding problems such as thread wear or welding residue.

[0020] In this embodiment, the inlet mounting post 31 and the outlet mounting post 32 are provided with internal threads to facilitate connection with the external threads of the inlet and outlet pipes. Preferably, the inlet mounting post 31 and the outlet mounting post 32 are provided with metal mounting rings 5 ​​with internal threads, and the metal mounting rings 5 ​​and the main body of the mounting base 3 are formed by a secondary injection molding process. Furthermore, the outer side of the metal mounting rings 5 ​​is provided with several annular grooves to improve the connection strength with the main body of the mounting base 3.

[0021] The metal mounting ring 5 refers to the annular metal component embedded inside the mounting post, which can be made of copper alloy or stainless steel. It is integrated with the main body of the mounting base 3 through a secondary injection molding process to enhance the mechanical strength of the threaded connection. The annular groove refers to the ring-shaped recessed structure on the outer surface of the metal mounting ring 5, used to increase the contact area between the metal mounting ring 5 and the plastic substrate. By using a direct internal thread connection, the valve core seat structure is eliminated while ensuring sealing performance, reducing overall assembly steps and material costs. This allows for direct and rapid installation of the inlet and outlet pipes, eliminating the extra space occupied by traditional valve core seats, resulting in a more compact water outlet device structure. Simultaneously, the cooperation between the metal mounting ring 5 and the annular groove ensures the stability and reliability of the threaded connection during long-term use.

[0022] Combination Figures 1 to 2As shown, in this embodiment, the control body 1 includes an operating component 13, a movable piece 12 connected to the operating component 13, and a fixed piece 11 disposed below the movable piece 12. The fixed piece 11 has an inlet channel and an outlet channel that connect the inlet mounting column 31 and the outlet mounting column 32. The movable piece 12 has a connecting groove on the side facing the fixed piece 11 to control the opening and closing of the inlet channel and the outlet channel.

[0023] The operating component 13 is used to drive the rotating plate 12, and can be implemented as a knob or handle. It transmits external force to the rotating plate 12 through a mechanical connection. The rotating plate 12 is a movable component that is linked with the operating component 13 and covers the fixed plate 11. Its rotational movement changes its relative position with the fixed plate 11. The fixed plate 11 is a component fixed on the mounting base 3 and has a fixed flow channel. Its water inlet channel and water outlet channel correspond to the positions of the water inlet mounting column 31 and the water outlet mounting column 32, respectively. The connecting groove is a groove structure formed on the surface of the rotating plate 12. It can be implemented as an arc-shaped groove or a straight groove. When the rotating plate 12 rotates, the connecting groove connects or blocks the water inlet channel and the water outlet channel of the fixed plate 11. When the operating component 13 is subjected to external force, it drives the rotating plate 12 to rotate around its axis. The connecting groove at the bottom of the rotating plate 12 changes its alignment with the water inlet channel and the water outlet channel inside the fixed plate 11 as it rotates. When the connecting groove covers both the inlet and outlet channels, water flows through it, forming a passage. When the moving plate 12 rotates, causing the connecting groove to deviate from the outlet channel, the water flow is blocked. The contact surface between the fixed plate 11 and the moving plate 12 achieves water flow control through a planar seal, eliminating the need for a separate valve body structure. By directly contacting the moving plate 12 and the fixed plate 11 with the connecting groove structure, the water flow control function is integrated into the valve core, reducing the number of parts and assembly complexity. In this embodiment, through holes are formed on the fixed plate 11, the moving plate 12, the operating member 13, and the mounting base 3 to form a pull-out channel 4 in the axial direction. It should be noted that the inlet channel, outlet channel, and connecting groove are all located on the outside of the pull-out channel 4. The central through hole of the fixed plate 11 and the central hole of the moving plate 12 form an aligned guide path, and the central hole of the operating member 13 extends this path to the clearance hole of the mounting base 3, thereby forming a continuous cylindrical channel. When the outlet pipe passes through this channel, its pipe wall maintains a clearance fit with the inner wall of the channel, so that the outlet pipe is not radially constrained by the fixed plate 11, the moving plate 12, and the operating member 13 during the pull-out process. This solution integrates the pull-out channel 4 inside the control mechanism, so that the width of the valve core body only needs to meet the space required for the rotation of the moving plate 12, without reserving a lateral clearance area for the pull-out pipe. At the same time, the mounting base 3 directly integrates the pipe connection structure, eliminating the need for a separate valve core seat component.

[0024] It should be noted that in some embodiments, two inlet mounting columns 31 can be provided for connecting cold water and hot water. The outlet mounting column 32 is positioned on the line of symmetry between the two inlet mounting columns 31 and on the opposite side of the pull-out channel 4. The line of symmetry refers to the perpendicular bisector of the line connecting the center points of the two inlet mounting columns 31. The two inlet mounting columns 31 are respectively arranged at the bottom of the valve core, and the outlet mounting column 32 is located in the extension direction of the line of symmetry, forming a spatial misalignment with the pull-out channel 4. Because the outlet mounting column 32 is located far from the inlet mounting columns 31, the bending path of the outlet pipe will not spatially interfere with the inlet pipe during installation.

[0025] Through the above technical solution, this application achieves direct pipe installation and pull-out function integration of the water outlet device, reducing component costs and assembly difficulty, while also reducing the overall size of the device. The free movement of the water outlet pipe within the pull-out channel 4 can adapt to different usage scenarios, eliminating the need for additional pull-out pipes for connection, which helps reduce material costs.

[0026] It should be understood that the above are only preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
