Description

Technical Field

[0001] This application relates to the field of faucet conversion technology, and more particularly to a conversion component for a faucet. Background Technology

[0002] In existing technologies, three-hole fixed valve cores are typically used in conjunction with valve stems and other structures to regulate the temperature and flow rate of pre-stored cold and hot mixed water. However, this structure has significant drawbacks when applied to instant-heating faucets. On the one hand, instant-heating systems have specific requirements for water circuit layout, which traditional three-hole fixed valve cores cannot directly adapt to; establishing a completely new production line for this would lead to a surge in costs. On the other hand, forcibly adapting the system would result in uneven water circuit transitions, affecting water output efficiency and user experience.

[0003] To address the aforementioned issues, simply adding an interface conversion component between the existing valve core and the water circuit would introduce new problems. The introduction of this conversion component would alter the spatial structure and assembly logic of the entire assembly. Improper design could easily lead to complex assembly processes, reduced sealing reliability, and even difficulty in achieving stable installation within a limited space. Therefore, there is room for further improvement in achieving efficient water circuit conversion while ensuring a compact overall structure, convenient assembly, and reliable sealing. Utility Model Content

[0004] This application proposes a conversion component for a water tap, which aims to optimize the compatibility between instant heating taps and traditional valve cores, and improve the assembly complexity and sealing reliability issues caused by water circuit conversion.

[0005] Specifically, this conversion component integrates a traditional fixed valve core into an instant heating system through the cooperation of a conversion element with a specific water channel and the housing. This allows existing valve core production lines to be adapted to the new system without major modifications, and ensures a stable water connection and good sealing, thereby improving production efficiency and product reliability.

[0006] The conversion component for a water tap provided in this application adopts the following technical solution: A conversion component for a water tap, comprising: A converter has a first end and a second end. The first end has a first interface and a second interface, and the second end has a third interface, a fourth interface, and a fifth interface. A first flow channel and a second flow channel are formed inside the converter. The first flow channel connects the first interface and the third interface. The second flow channel extends from the second interface and branches to the fourth interface and the fifth interface. A fixed valve core, wherein three valve core ports are provided on the fixed valve core; The housing contains both the conversion element and the fixed valve core. The second end of the conversion element and the fixed valve core abut against each other and form a sealed fit under the constraint of the housing, so that the three valve core ports are respectively connected to the third interface, the fourth interface and the fifth interface.

[0007] By adopting the above technical solution, during installation, firstly, the adapter is placed inside the housing, with its second end facing the installation direction; then, the fixed valve core is placed inside the housing, aligning it with the second end of the adapter; finally, the adapter and the fixed valve core are axially pressed together by the housing's sealing structure (usually an end cap, but could also be a snap-fit, etc.) until they are tightly abutted and form a seal. The external water pipe is connected to the first and second ports on the first end of the adapter. The three valve ports on the fixed valve core are respectively connected to the third, fourth, and fifth ports on the second end of the adapter. When a user operates the faucet to drive the water flow, the water from different interfaces is mixed and distributed within the faucet before finally flowing out of the faucet outlet. Through the specific flow channel design inside the converter, the water path conversion and distribution are achieved, enabling the standard valve core to adapt to the needs of various water systems. The converter and the valve core are integrated into a stable module through the housing, resulting in a relatively simple overall structure and a reliable sealing solution. This allows existing valve core production lines to adapt to new systems without major modifications, ensuring a stable water connection and good sealing, thereby improving production efficiency and product reliability.

[0008] Preferably, the conversion element is L-shaped, with the axial center lines of its first end and second end perpendicular to each other; the first flow channel is a straight flow channel extending axially along the conversion element; the second flow channel includes a main pipe section, a branch section, and a first branch pipe section and a second branch pipe section connected together, the main pipe section is connected to the second interface, the branch section is used to connect the main pipe section with the first branch pipe section and the second branch pipe section, and the first branch pipe section and the second branch pipe section are respectively connected to the fourth interface and the fifth interface.

[0009] By adopting the above technical solution, a clear water path conversion and distribution function is achieved. Specifically, the external water flow enters from the first interface, is directly transported to the third interface through the first flow channel, and enters the valve core and other components for water flow regulation. Then the water flow enters from the fourth and fifth interfaces, flows through the first and second branch pipe sections respectively, is collected in the branch section, and then flows out from the second interface through the main pipe section to complete a cycle.

[0010] Preferably, the conversion component is cylindrical, with its first end and second end located on the same axis; the first flow channel is a straight flow channel extending axially along the conversion component; the second flow channel includes a main pipe section, a first branch pipe section and a second branch pipe section connected together, one end of the main pipe section is connected to the second interface, and the other end is connected to the first branch pipe section and the second branch pipe section, and the first branch pipe section and the second branch pipe section are respectively connected to the fourth interface and the fifth interface.

[0011] By adopting the above technical solution, a clear water path conversion and distribution function is achieved. Specifically, the external water flow enters from the first interface, is directly transported to the third interface through the first flow channel, and enters the valve core and other components for water flow regulation. Then the water flow enters from the fourth and fifth interfaces, flows through the first and second branch pipe sections respectively, and then flows out from the second interface through the main pipe section, completing one cycle.

[0012] Preferably, a sealing groove is provided at one end of the valve core near the conversion element, the sealing groove is arranged around the valve core opening, and a sealing element is provided on the sealing groove.

[0013] By adopting the above technical solution, when the outer shell presses the fixed valve core and the conversion component together, the sealing component in the sealing groove is compressed, thereby forming a tight seal between the two, ensuring the independence of each water path at the mating surface of the fixed valve core and the conversion component, effectively preventing water leakage between different water paths, avoiding cross-contamination, and ensuring the accuracy of water flow control.

[0014] Preferably, the outer casing has a stepped through hole; the end of the conversion component near the fixed valve core has a shaft protrusion, which is inserted into the stepped through hole of the outer casing.

[0015] By adopting the above technical solution, when installing the conversion component, the axle at its end is aligned and inserted into the stepped through hole on the housing. The cooperation between the axle and the stepped through hole provides precise radial positioning for the conversion component and also ensures that the position of the conversion component is fixed inside the housing. This allows the third, fourth, and fifth interfaces on the conversion component to automatically and accurately align with the three valve core ports on the valve core, improving the accuracy and efficiency of assembly and avoiding leakage or functional failure caused by misalignment.

[0016] Preferably, it also includes a valve core shell, the fixed valve core is located inside the valve core shell, the fixed valve core is provided with a positioning protrusion, and the valve core shell is provided with a positioning groove, the positioning protrusion and the positioning groove are inserted to realize the cooperation between the fixed valve core and the valve core shell.

[0017] By adopting the above technical solution, when assembling the fixed valve core and the valve core shell, the positioning protrusion on the fixed valve core is aligned with the positioning groove on the valve core shell, and pressure is applied along the axial direction until the protrusion is inserted into the groove. This not only ensures the stability of the installation position between the fixed valve core and the valve core shell, but also enables the fixed valve core to be installed quickly and without tools. The installation speed is fast, which helps to improve production efficiency, and the connection is firm and reliable.

[0018] Preferably, it further includes a valve core housing, a valve assembly, and a gear housing. The fixed valve core is located at one end inside the valve core housing, the other end of the valve core housing is connected to the valve assembly, the other end of the valve assembly is connected to the gear housing, and the outer diameter of the valve assembly is larger than the outer diameter of the valve core housing, so that the valve assembly is also inserted into the stepped through hole.

[0019] By adopting the above technical solution, the insertion of the valve kit into the stepped through hole provides a second important radial support point for the entire valve core module, so that the valve kit and the axle of the conversion component together form a stable two-point support, which greatly enhances the rigidity and stability of the entire component inside the faucet.

[0020] Preferably, the housing is provided with a mounting post, and the valve assembly is fixedly connected to the mounting post.

[0021] By adopting the above technical solution, the valve assembly is fixed to the mounting post on the inner wall of the housing using screws or a snap-fit ​​structure. This connection provides the final axial and radial fastening of the valve assembly, preventing loosening of the valve assembly and its related connection structure in any direction, ensuring the absolute stability of the product under long-term use and various operating conditions, and improving the product's durability and reliability.

[0022] Preferably, the inner wall of the outer casing is uniformly provided with mounting posts, and the outer wall of the conversion component is provided with mounting grooves for avoiding the mounting posts.

[0023] By adopting the above technical solution, when installing the conversion component, the mounting groove on its outer wall must be aligned with and avoid the mounting post on the inner wall of the housing in order to install it smoothly. This ensures that the conversion component can only be installed into the housing at the only correct angle, thereby ensuring that the first and second interfaces at its first end can be correctly connected to the external water pipe. This eliminates water leakage or functional abnormalities caused by assembly errors, and improves the production yield and maintenance efficiency.

[0024] Preferably, the housing includes a housing and an end cap detachably connected to the housing; the conversion element is housed within the housing, the fixed valve core is constrained between the conversion element and the end cap, and the fixed valve core and the conversion element are pressed together by tightening the end cap.

[0025] By adopting the above technical solution, the conversion component is placed into the housing in sequence, followed by the fixed valve core (and its components), and finally the end cap is tightened. The screwing in of the end cap applies axial pressure to the fixed valve core and presses it against the conversion component. The structure is simple, and assembly and subsequent maintenance are very convenient. By controlling the tightening torque of the end cap, the clamping force on the sealing surface can be precisely controlled, optimizing the sealing effect while avoiding crushing the sealing component.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When the user operates the faucet to drive the water flow, the water from different interfaces is mixed and distributed within the faucet and finally flows out from the faucet outlet. Through the specific flow channel design inside the conversion component, the water circuit conversion and distribution are realized, enabling the standard valve core to adapt to the needs of various water circuit systems. The conversion component and the valve core are integrated into a stable module through the housing. The overall structure is relatively simple and provides a reliable sealing solution. As a result, the original valve core production line can be adapted to the new system through the conversion component without major modifications, and the water circuit connection is stable and well sealed, thereby improving production efficiency and product reliability. 2. The insertion of the valve kit into the stepped through hole provides a second important radial support point for the entire valve core module, enabling the valve kit and the axle of the conversion component to form a stable two-point support, which greatly enhances the rigidity and stability of the entire component inside the faucet. 3. When installing the adapter, the mounting groove on its outer wall must be aligned with and avoid the mounting post on the inner wall of the housing to ensure successful installation. This ensures that the adapter can only be installed into the housing at the correct angle, thereby ensuring that the first and second interfaces at its first end can be correctly connected to the external water pipe. This eliminates water leakage or functional abnormalities caused by assembly errors, and improves production yield and maintenance efficiency. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0030] Example 1 This application discloses a conversion component for a water tap.

[0031] Reference Figures 1 to 6 The conversion assembly includes a conversion component 1, a fixed valve core 2, and a housing 3. The conversion component 1 has a first end and a second end. The first end has a first interface 11 and a second interface 12, and the second end has a third interface 13, a fourth interface 14, and a fifth interface 15. The conversion component 1 has a first flow channel 16 and a second flow channel 17. The first flow channel 16 connects the first interface 11 and the third interface 13. The second flow channel 17 extends from the second interface 12 and branches to the fourth interface 14 and the fifth interface 15. The fixed valve core 2 has three valve core ports 21. The conversion component 1 and the fixed valve core 2 are both housed in the housing 3. The second end of the conversion component 1 and the fixed valve core 2 abut against each other under the constraint of the housing 3 and form a sealed fit, so that the three valve core ports 21 are respectively connected to the third interface 13, the fourth interface 14, and the fifth interface 15.

[0032] The converter 1 is L-shaped, with the axial centerlines of its first and second ends perpendicular to each other. The first flow channel 16 is a straight flow channel extending axially along the converter 1; the second flow channel 17 includes a main pipe section 171, a branch section 172, and a first branch pipe section 173 and a second branch pipe section 174 connected together. The main pipe section 171 is connected to the second interface 12, and the branch section 172 is used to connect the main pipe section 171 with the first branch pipe section 173 and the second branch pipe section 174. The first branch pipe section 173 and the second branch pipe section 174 are respectively connected to the fourth interface 14 and the fifth interface 15. This design achieves a clear water path conversion and distribution function. Specifically, external water enters from the first port 11, flows directly through the first flow channel 16 to the third port 13, enters the valve core 2 and other components for water flow regulation; then the water enters from the fourth port 14 and the fifth port 15, flows through the first branch pipe section 173 and the second branch pipe section 174 respectively, converges in the branch section 172, and then flows out from the second port 12 through the main pipe section 171, completing one cycle.

[0033] The conversion component 1 adopts an L-shaped structure with a bend, and the axial center lines of its first and second ends are perpendicular to each other. This structural design allows the conversion component to better adapt to the spatial layout requirements inside the faucet, providing greater flexibility for faucet design. Before the second flow channel 17 branches and connects to the fourth interface 14 and the fifth interface 15, a guide surface 7 is formed inside to guide and stabilize the water flow. This design can effectively reduce turbulence, eddies and energy loss caused by abrupt changes in flow direction, thereby significantly reducing water flow noise and vibration, and improving the smoothness of water flow and user experience.

[0034] The housing 3 includes a housing 31 and an end cap 32 detachably connected to the housing 31. The conversion element 1 is housed within the housing 31, and the fixed valve core 2 is confined between the conversion element 1 and the end cap 32. During installation, the conversion element 1 is first placed into the housing 3 with its second end facing the installation direction. Then, the fixed valve core 2 is placed into the housing 3, aligning it with the second end of the conversion element 1. Finally, the fixed valve core 2 and the conversion element 1 are axially pressed together by tightening the end cap 32 until a reliable seal is formed. This assembly process is simple and efficient. By controlling the tightening torque of the end cap 32, the pressure of the sealing surface can be precisely controlled, which optimizes the sealing effect and avoids excessive compression that could damage the sealing element 23.

[0035] To ensure reliable sealing, a sealing groove 22 is provided at one end of the valve core 2 near the switching element 1, which is annularly arranged around the valve core opening 21. A sealing element 23 is provided on the sealing groove 22. When the outer shell 3 presses the valve core 2 and the switching element 1 together, the sealing element 23 in the sealing groove 22 is compressed, thereby forming a tight seal between the two. This ensures the independence of each water path at the mating surface of the valve core 2 and the switching element 1, effectively prevents water leakage between different water paths, avoids cross-contamination, and ensures the accuracy of water flow control.

[0036] To improve assembly accuracy, a stepped through hole 311 is provided on the housing 3. A shaft protrusion 18 is provided at the end of the conversion component 1 near the fixed valve core 2. The shaft protrusion 18 is inserted into the stepped through hole 311 of the housing 3. This design provides precise radial positioning for the conversion component 1, ensuring that the position of the conversion component 1 is fixed in the housing 3. This allows the third, fourth, and fifth interfaces on the conversion component 1 to automatically and accurately align with the three valve core ports 21 on the fixed valve core 2, improving the accuracy and efficiency of assembly and avoiding leakage or functional failure caused by misalignment.

[0037] The conversion assembly also includes a valve core housing 4, a valve assembly 5, and a gear housing 6. The fixed valve core 2 is located inside the valve core housing 4. The fixed valve core 2 is provided with a positioning protrusion 24, and the valve core housing 4 is provided with a positioning groove 41. The positioning protrusion 24 can be inserted into the positioning groove 41 to achieve the cooperation between the fixed valve core 2 and the valve core housing 4. This quick-installation structure allows the fixed valve core 2 and the valve core housing 4 to be assembled by simply aligning the positioning protrusion 24 on the fixed valve core 2 with the positioning groove 41 on the valve core housing 4 and applying axial pressure until the protrusion is inserted into the groove, thereby achieving stable fixation of the installation position. This not only achieves quick and tool-free installation of the fixed valve core 2, improving production efficiency, but also ensures a firm and reliable connection.

[0038] The other end of the valve core housing 4 is connected to the valve assembly 5, and the other end of the valve assembly 5 is connected to the gear housing 6. The outer diameter of the valve assembly 5 is larger than the outer diameter of the valve core housing 4, so that the valve assembly 5 is also inserted into the stepped through hole 311. This design provides a second important radial support point for the entire valve core module, so that the valve assembly 5 and the shaft protrusion 18 of the conversion part 1 form a stable two-point support, which greatly enhances the rigidity and stability of the entire component inside the faucet.

[0039] The other structures of the faucet in this embodiment (including other components inside the housing) are the same as those in the prior art, so they will not be described in detail here.

[0040] Furthermore, the axial length of the valve assembly 5 is less than or equal to half the axial length of the valve core shell 4. This compact design saves materials and reduces manufacturing costs while meeting the functions of valve assembly 5 such as support and connection. At the same time, it optimizes the internal structural layout of the faucet, making the product design more compact.

[0041] To enhance the stability of the overall structure, a mounting post 312 is provided inside the housing 3. The valve assembly 5 is fixedly connected to the mounting post 312 by screws or snap-fit ​​structure. This connection provides the final axial and radial fastening of the valve assembly 5, preventing the valve assembly 5 and its related connection structure from loosening in any direction, ensuring the absolute stability of the product under long-term use and various working conditions, and improving the durability and reliability of the product.

[0042] Meanwhile, the inner wall of the outer casing 3 is uniformly provided with mounting posts 312, and the outer wall of the conversion component 1 is provided with mounting grooves 19 for avoiding the mounting posts 312. When installing the conversion component 1, the mounting grooves 19 on its outer wall must be aligned with and avoid the mounting posts 312 on the inner wall of the outer casing 3 in order to be successfully installed in place. This error-proof design ensures that the conversion component 1 can only be installed into the outer casing 3 at the only correct angle, thereby ensuring that the first and second interfaces at its first end can be correctly connected to the external water pipe, eliminating water leakage or functional abnormalities caused by assembly errors, and improving the production yield and maintenance efficiency.

[0043] Through the above technical solution, the conversion component of this embodiment realizes the conversion and distribution of water circuits through the specific flow channel design inside the conversion component 1, enabling the standard fixed valve core 2 to adapt to the needs of more complex water circuit systems. At the same time, the conversion component 1 and the fixed valve core 2 are integrated into a stable module through the housing 3, which simplifies the overall structure and provides a reliable sealing solution. As a result, the original valve core production line can be adapted to the new system through the conversion component 1 without major modifications, and the water circuit connection is stable and well sealed, thereby achieving the effect of improving production efficiency and product reliability.

[0044] Furthermore, in this embodiment, Example 2 Reference Figures 7 to 13 This embodiment provides another conversion component for a water tap, whose basic structure and working principle are the same as those of Embodiment 1. The main difference between the two lies in the specific shape of the conversion component 1.

[0045] In this embodiment, the conversion component 1 has a linear structure, that is, its first end and second end are located on the same axis, and the whole is cylindrical. This integrated coaxial layout makes the internal first flow channel 16 and second flow channel 17 paths more direct, the processing technology is relatively simple, and it helps to reduce manufacturing costs.

[0046] The first flow channel 16 is a straight flow channel extending along the axial direction of the conversion component 1; the second flow channel 17 includes a main pipe section 171, a branch section 172, a first branch pipe section 173, and a second branch pipe section 174 that are connected. The main pipe section 171 is connected to the second interface 12. The branch section 172 is used to connect the main pipe section 171 with the first branch pipe section 173 and the second branch pipe section 174. The first branch pipe section 173 and the second branch pipe section 174 are respectively connected to the fourth interface 14 and the fifth interface 15. This design also realizes a clear water path conversion and distribution function. Specifically, external water enters from the first port 11, flows directly through the first flow channel 16 to the third port 13, enters the valve core 2 and other components for water flow regulation; then the water enters from the fourth port 14 and the fifth port 15, flows through the first branch pipe section 173 and the second branch pipe section 174 respectively, converges in the branch section 172, and then flows out from the second port 12 through the main pipe section 171, completing one cycle.

[0047] Since the conversion component 1 is straight, its matching outer shell 3 is also designed to be cylindrical, and the internal space structure is more regular. This structural solution is particularly suitable for faucet products with ample internal space and high requirements for the straightness of the water circuit layout, providing another optimized option for product design.

[0048] Apart from the difference in the shape of the conversion component 1, this embodiment is consistent with embodiment 1 in all other technical features, such as the sealing fit of the fixed valve core 2, the quick-installation structure of the valve core shell 4, the two-point support of the valve assembly 5, and the error-proof design of the mounting column 312. It also achieves all the beneficial effects of reliable water circuit conversion, quick assembly and stable sealing.

[0049] The other structures of the faucet in this embodiment (including other components inside the housing) are the same as those in the prior art, so they will not be described in detail here.

[0050] Furthermore, in this embodiment, the branch section 172 can be removed, so that the first branch section 173 and the second branch section 174 are directly connected to the main section 171.

[0051] By providing two conversion parts, one straight and one L-shaped, this invention can flexibly adapt to faucets of different structural types, meeting diverse market and application needs.

[0052] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
