[0027] At least two mechanical valves; and

[0028] A valve bracket is provided for connection to the housing assembly. The valve bracket includes a first mounting portion and a second mounting portion connected to each other. Each of the mechanical valves is mounted on the first mounting portion. The second mounting portion has a water pipe and an inlet and a drain port communicating with the water pipe. The outlet of each of the mechanical valves is connected to the inlet through the water circuit assembly.

[0029] In some embodiments, a plurality of spaced-apart limit slots are provided on the same side of the first mounting portion.

[0044] Thirdly, embodiments of this application provide a drinking water device that includes the valve assembly described above.

[0045] The mechanical valve of this embodiment is applied in a drinking water device. The mechanical valve includes a valve body, a first sealing ring, a valve stem, a pressing assembly, and a spring. In actual operation, the user operates the pressing assembly to drive the valve stem to move axially between the inlet and outlet chambers of the valve body, thereby controlling the flow of water between the inlet and outlet chambers. Specifically, when the pressing assembly is first pressed and in the first state, it drives the valve stem to move axially. During this process, the spring is moderately compressed, and a certain distance is maintained between the sealing surface on the valve stem and the first sealing ring, ensuring smooth flow between the inlet and outlet chambers and allowing water to flow freely. When the pressing assembly is pressed again, entering the second state, the spring uses its restoring force to push the valve stem in the opposite direction. At this time, the sealing surface tightly abuts against the first sealing ring, effectively isolating the inlet and outlet chambers and achieving complete water flow cutoff.

[0046] This mechanical valve design is not only simple in structure and low in manufacturing cost, but also greatly simplifies the valve's structure and improves operational convenience while achieving effective water flow control. Furthermore, during the valve stem's movement, the first sealing ring remains stably located at its mounting point, ensuring positional stability and thus guaranteeing a tight seal. Simultaneously, because the water flow direction from the inlet to the outlet chamber is consistent with the axial movement direction of the valve stem, and the elastic thrust provided by the spring is also in the same direction, this design effectively reduces the impact of water pressure on the mechanical valve's movement, thereby significantly improving its pressure-bearing capacity.

[0059] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0061] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0062] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0064] The first aspect of this application discloses a drinking water device, which can be a water purifier or a water dispenser, etc., whose core function is to provide clean drinking water to meet the user's daily drinking water needs. In terms of water supply methods, this drinking water device exhibits high flexibility. It can be connected to bottled water, using bottled water as a water source to supply drinking water to the user. Simultaneously, it can also be directly connected to a tap water pipe, using tap water as a water supply source. The drinking water device includes a housing assembly and a water circuit assembly housed within the housing assembly. The housing assembly, as the main structure of the drinking water device, not only plays a crucial role in supporting and protecting the internal components but also ensures the overall aesthetics and durability of the drinking water device. The water circuit assembly is the core component for realizing the water supply function; it includes various necessary water pipes and other components to ensure smooth and stable water flow. Furthermore, the drinking water device also includes a filtration assembly that can filter the water.

[0065] Please refer to Figures 1 to 3. A second aspect of this application proposes a valve assembly 10, which, in an embodiment of this application, includes at least two mechanical valves 100 and a valve support 200.

[0066] The valve bracket 200 is used to connect to the housing assembly. The valve bracket 200 includes a first mounting portion 201 and a second mounting portion 202 that are connected to each other. It should be noted that, from a structural strength perspective, the first mounting portion 201 and the second mounting portion 202 can be designed as a single unit. This design ensures that the overall structure of the valve bracket 200 is robust and stable, capable of withstanding significant external forces without easily being damaged. However, for maintainability, the first mounting portion 201 and the second mounting portion 202 can also be connected using detachable methods such as screws or clips. This design makes the assembly and disassembly of the valve bracket 200 more convenient, facilitating subsequent replacement and maintenance. When a part malfunctions or needs upgrading, it can be easily disassembled without replacing the entire valve bracket 200, thus reducing maintenance costs. When connecting to the housing assembly, either the first mounting portion 201 or the second mounting portion 202 of the valve bracket 200 is connected to the housing assembly to achieve basic connection and fixation. This design satisfies basic connection requirements while ensuring the stability of the connection. Furthermore, to further enhance connection stability, the first mounting part 201 and the second mounting part 202 can be simultaneously connected to the housing assembly. This dual connection significantly strengthens the connection between the valve assembly 10 and the housing assembly, ensuring stable operation in various complex working environments.

[0067] Each mechanical valve 100 is installed in the first mounting section 201. The second mounting section 202 has a water pipe 2023 and an inlet 2021 and an outlet 2022 connected to the water pipe 2023. The outlet 101d of each mechanical valve 100 is connected to the inlet 2021 through a water circuit assembly. It is understood that the water pipe 2023 can be a single, straight pipe to meet simple and direct water flow requirements, or it can be multiple segments arranged at an angle to adapt to more complex and varied spatial layouts and water flow paths. The direct application of the outlet 2022 as the water inlet / outlet of the drinking water equipment further enhances the practicality and convenience of this design. Users can directly obtain drinking water after passing through the mechanical valves 100 through the outlet 2022 without additional conversion equipment or pipes.

[0068] The valve assembly 10 of this application embodiment is applied in a drinking water device. The valve assembly 10 includes at least two mechanical valves 100 and a valve bracket 200. The valve bracket 200 includes a first mounting part 201 and a second mounting part 202. Each mechanical valve 100 is mounted on the first mounting part 201, thus realizing the integrated setting of multiple mechanical valves 100. This integrated design not only facilitates subsequent modular assembly, but also significantly improves space utilization and assembly efficiency, making the internal structure of the drinking water device more neat and orderly. At the same time, the second mounting part 202 also has a water pipe 2023, and is also provided with an inlet 2021 and a drain 2022 connected to the water pipe 2023, that is, a water circuit is formed on the valve bracket 200, thereby reducing the need for subsequent assembly of additional water circuit components, reducing installation difficulty, and making the overall valve assembly 10 structure more compact and easier to install, and the subsequent maintenance process also becomes more efficient and convenient.

[0069] Referring to Figures 2 to 4, in some structural configurations, the first mounting portion 201 has multiple spaced-apart limiting slots 201B on the same side. The mechanical valve 100 includes a valve body 101 and a first protrusion 108 connected to the outer wall of the valve body 101, with the first protrusion 108 embedded in the limiting slot 201B. The multiple limiting slots 201B enable independent and stable fixing of multiple mechanical valves 100. Each limiting slot 201B forms a tight fit with the first protrusion 108 of the mechanical valve 100. This tight fit not only ensures the accurate positioning of each mechanical valve 100 after installation but also effectively prevents potential shaking or misalignment during operation, thus greatly reducing the risk of functional failure caused by these factors. This design not only improves the stability and reliability of the entire system but also demonstrates significant advantages in actual operation. The snap-fit ​​method is simpler and faster than traditional fixing methods, greatly improving assembly efficiency. At the same time, when mechanical valve 100 needs to be repaired or replaced, this snap-fit ​​method makes the operation more convenient, thereby further improving the efficiency of maintenance.

[0070] In related technical fields, drinking water equipment typically needs to be equipped with a mechanical valve to ensure effective control of water flow. This mechanical valve usually takes the form of a knob. However, this type of knob-type mechanical valve is not only relatively complex in structure, but also requires a large amount of force to turn, which makes the operation less smooth and affects the user experience.

[0071] To address the aforementioned issues, referring to Figures 5 to 7, the mechanical valve 100 further includes a first sealing ring 102, a valve stem 103, a pressing assembly 104, and a spring 105. The valve body 101 has an inlet chamber 101A and an outlet chamber 101B, and a connecting port 101C linking the inlet chamber 101A and the outlet chamber 101B. The valve body 101 includes a mounting portion 101a located within the inlet chamber 101A. It is understood that the inlet chamber 101A receives the fluid input from the outside, while the outlet chamber 101B outputs the fluid to the next stage. This design ensures orderly fluid flow within the valve body 101. It should be noted that the flow area of ​​the inlet chamber 101A is designed to be larger than that of the outlet chamber 101B, thus achieving throttling and pressure reduction. When fluid passes through the valve body 101, the flow rate and pressure change accordingly due to the change in flow area. This change helps to regulate and control the flow rate and pressure of the fluid, thereby achieving more precise and stable fluid control. The opening shape of the connector 101C can be a regular shape such as a circle or a square to facilitate processing and manufacturing.

[0072] The first sealing ring 102 is connected to the mounting part 101a and surrounds the communication port 101C. The first sealing ring 102 can be made of silicone or rubber, etc., so that the first sealing ring 102 has excellent resistance to corrosion, tearing and compression deformation. The valve stem 103 is movably disposed in the valve body 101 and is at least partially located in the inlet chamber 101A and the outlet chamber 101B. The portion of the valve stem 103 located in the inlet chamber 101A has a sealing surface 103A facing the first sealing ring 102. The specific movement of the valve stem 103 is sliding along the setting direction of the inlet chamber 101A and the outlet chamber 101B. This sliding movement allows the valve stem 103 to accurately control the flow and achieve precise flow regulation. At the same time, the sliding design of the valve stem 103 also facilitates the maintenance and operation of the valve. In terms of material selection, the valve stem 103 can be made of plastic. Plastic material has the advantages of being lightweight, corrosion-resistant and easy to process, which can meet the usage requirements of the mechanical valve 100 in different working environments. Furthermore, the plastic valve stem 103 possesses excellent wear resistance and anti-aging properties, extending the service life of the mechanical valve 100. A pressing assembly 104 is connected to the valve body 101 and to the valve stem 103. One end of the pressing assembly 104 has a mounting hole, into which one end of the valve stem 103 is inserted. Thus, the pressing assembly 104 drives the valve stem 103 to move axially and switch between the first and second states. It should be noted that the structure of the pressing assembly 104 is inspired by similar designs in existing ballpoint pens. These designs typically include self-locking mechanisms such as ratchet mechanisms to ensure the stability and reliability of the pressing action. In ballpoint pens, this pressing assembly 104 is installed at the end. When the user presses the end, the ratchet mechanism drives the pen tip downwards and locks it in place, placing the pen tip in a writeable state. When the user presses the end again, the ratchet mechanism moves in the opposite direction, causing the pen tip to retract into the pen barrel, placing it in a non-writeable state. Applying this existing pressing component 104 structure to a mechanical water valve can achieve similar functionality. The user only needs to gently press the pressing component 104 to drive the valve stem 103, thereby changing the state of the mechanical valve 100. This design not only improves the ease of operation of the mechanical valve 100 but also ensures its stability and reliability. A spring 105 is located within the inlet chamber 101A, with both ends of the spring 105 abutting against the valve stem 103 and the cavity wall of the inlet chamber 101A, respectively, providing a thrust acting on the valve stem 103 and along its axial direction towards the pressing component 104. Specifically, when the pressing component 104 is in its first state, the sealing surface 103A is spaced apart from the first sealing ring 102, allowing the inlet chamber 101A and the outlet chamber 101B to be in a conductive state. When the pressing component 104 is in its second state, the sealing surface 103A abuts against the first sealing ring 102, thus isolating the inlet chamber 101A and the outlet chamber 101B.

[0073] In actual operation, the user drives the valve stem 103 to move axially between the inlet chamber 101A and the outlet chamber 101B of the valve body 101 by manipulating the pressing component 104, thereby controlling the opening and closing of the inlet chamber 101A and the outlet chamber 101B. Specifically, when the pressing component 104 is pressed for the first time and is in the first state, it drives the valve stem 103 to move axially. During this process, the spring 105 is moderately compressed, and at the same time, a certain distance is maintained between the sealing surface 103A on the valve stem 103 and the first sealing ring 102, thereby ensuring smooth conduction between the inlet chamber 101A and the outlet chamber 101B, allowing water to flow freely. When the pressing component 104 is pressed again, causing it to enter the second state, the spring 105 uses its restoring force to push the valve stem 103 to move in the opposite direction. At this time, the sealing surface 103A tightly abuts against the first sealing ring 102, effectively isolating the inlet chamber 101A and the outlet chamber 101B, achieving complete water flow cutoff. This mechanical valve 100 design is not only simple in structure and low in manufacturing cost, but also greatly simplifies the structure of the mechanical valve 100 while achieving effective water flow control, improving operational convenience. Furthermore, during the movement of the valve stem 103, the first sealing ring 102 remains stably located at its mounting portion 101a. This design ensures the positional stability of the first sealing ring 102, thereby guaranteeing the sealing effect. Meanwhile, since the water flow direction from the inlet chamber 101A to the outlet chamber 101B is consistent with the axial movement direction of the valve stem 103, and the elastic thrust provided by the spring 105 is also in the same direction, this design effectively reduces the influence of water flow pressure on the movement process of the mechanical valve 100, thereby significantly improving its pressure-bearing capacity.

[0074] Referring to Figure 9, in some structural configurations, the mounting portion 101a includes a cavity wall surface of the inlet chamber 101A. This cavity wall surface is positioned opposite to the sealing surface 103A and recessed to form a limiting groove 101b. The first sealing ring 102 is embedded within the limiting groove 101b and at least partially protrudes from it. This limiting groove 101b provides a stable support and positioning point for the first sealing ring 102, ensuring the stability and accuracy of the sealing ring after installation. When the valve stem 103 moves under the drive of the pressing assembly 104, the contact between the sealing surface 103A and the first sealing ring 102 becomes tighter and more reliable. The presence of the limiting groove 101b not only prevents deformation or displacement of the sealing ring under high pressure but also enhances the pressure-bearing capacity of the sealing surface 103A through its recessed structure. This design not only improves the sealing performance of the water valve but also extends the service life of the sealing ring, thereby reducing maintenance costs and replacement frequency. Of course, in other embodiments, the mounting part 101a can also be a sleeve structure directly disposed on the cavity wall of the water inlet chamber 101A. This design allows the first sealing ring 102 to be directly fitted onto the outer wall of the sleeve structure for fixation. This sleeve structure not only simplifies the installation process but also improves the stability and durability of the first sealing ring 102, further reducing maintenance costs and replacement frequency.

[0075] Optionally, the sealing surface 103A is planar. This planar sealing surface 103A provides a more uniform and stable contact area. When the valve stem 103 moves under the drive of the pressing assembly 104, causing the sealing surface 103A to contact the first sealing ring 102, the planar shape ensures a uniform distribution of contact pressure between the two, effectively preventing fluid leakage around the sealing surface 103A. Secondly, the processing and manufacturing of the planar sealing surface 103A is relatively simple, which helps reduce production costs and improve production efficiency. The planar shape is easy to precisely manufacture through machining or die forming, ensuring the consistency and reliability of the sealing surface 103A for each water valve.

[0076] In some structural forms, the push rod includes a rod body 1031 and a sealing part 1032 surrounding the circumference of the rod body 1031. The circumferential wall of the rod body 1031 is spaced apart from the cavity walls of the water inlet chamber 101A and the water outlet chamber 101B. The rod body 1031 is connected to the pressing assembly 104. The sealing part 1032 is located in the water inlet chamber 101A and abuts against the spring 105. The surface of the sealing part 1032 facing away from the spring 105 is the sealing surface 103A.

[0077] The rod body 1031 serves as the main structure of the push rod, with its peripheral wall maintaining a certain distance from the walls of the inlet chamber 101A and the outlet chamber 101B. This design not only avoids direct friction between the rod body 1031 and the chamber walls, reducing wear and energy consumption, but also provides a smooth channel for fluid flow between the inlet chamber 101A and the outlet chamber 101B. The sealing part 1032, a key component of the push rod, is located inside the inlet chamber 101A and abuts against the spring 105. It should be noted that the side of the sealing part 1032 facing away from the sealing surface 103A forms a stepped surface. This stepped surface not only provides a stable support point for the spring 105 but also makes the spring 105 more securely and reliably fixed. The surface of the sealing part 1032 facing away from the spring 105 is designed as a sealing surface 103A. When this surface contacts the first sealing ring 102, and the sealing surface 103A covers the communication port 101C, it can generate sufficient sealing pressure to ensure that fluid does not leak from the sealing surface 103A. In addition, the annular structure of the sealing part 1032 not only enhances the overall stability of the push rod, but also allows the sealing surface 103A to be evenly distributed around the periphery of the rod body 1031, thereby improving the reliability and durability of the seal. When the valve stem 103 moves under the drive of the pressing assembly 104, the contact area and contact pressure between the sealing surface 103A and the sealing element can be evenly distributed, further enhancing the sealing effect.

[0078] Furthermore, along the axial direction of the stem portion 1031, the projection of the sealing portion 1032 covers the first sealing ring 102. Firstly, this covering design ensures maximum contact area between the sealing portion 1032 and the first sealing ring 102. When the valve stem 103 moves under the drive of the pressing assembly 104, the sealing portion 1032 can fit tightly against the first sealing ring 102, and due to the complete coverage of the projection, the contact area between the two is fully guaranteed. This not only enhances the reliability of the seal but also improves the pressure-bearing capacity of the sealing surface 103A, enabling the mechanical valve 100 to maintain a stable sealing effect even under high-pressure environments. Secondly, this design helps reduce the risk of fluid leakage. Since the projection of the sealing portion 1032 completely covers the first sealing ring 102, even under adverse conditions such as prolonged operation of the mechanical valve 100 or external impact, fluid leakage from the tiny gap between the sealing surface 103A and the first sealing ring 102 can be effectively prevented. This not only improves the sealing performance of the mechanical valve 100, but also extends its service life and reduces maintenance costs and downtime caused by leakage.

[0079] Referring to Figure 8, in some structural configurations, the first sealing ring 102 has an annular rib 1021 on the side near the sealing surface 103A, and the annular rib 1021 surrounds the connecting port 101C. This arrangement allows the annular rib 1021 to act as a barrier, effectively preventing fluid leakage when the first sealing ring 102 contacts the sealing surface 103A. The presence of the annular rib 1021 effectively transforms the traditional surface seal into a more efficient line seal. Compared to surface seals, line seals offer the advantage of providing more concentrated sealing pressure. Since the annular rib 1021 is arranged around the connecting port 101C, when the first sealing ring 102 is under pressure, the annular rib 1021 will tightly adhere to the sealing surface 103A, forming a continuous and tight sealing line. This sealing method not only improves the reliability of the seal but also reduces the risk of leakage due to unevenness or wear of the sealing surface 103A. Furthermore, the design of the annular rib 1021 enhances the durability of the first sealing ring 102. Even if the sealing surface 103A experiences some wear during long-term use, the annular rib 1021 maintains its structural integrity and continues to provide an effective seal. This design not only extends the service life of the first sealing ring 102 but also reduces maintenance costs due to seal failure.

[0080] Referring to Figures 6, 9, and 10, in some structural configurations, the mechanical valve 100 further includes a second sealing ring 106 and a pressure plate 107. The valve body 101 has an annular protrusion 101e on the side near the pressing assembly 104. The annular protrusion 101e has a through hole 107B communicating with the water outlet chamber 101B. The valve stem 103 at least partially passes through the through hole 107B and is connected to the pressing assembly 104. The second sealing ring 106 is sleeved on the periphery of the valve stem 103. The pressure plate 107 is connected to the annular protrusion 101e and abuts against the second sealing ring 106, fixed within the through hole 107B.

[0081] The annular protrusion 101e not only enhances the overall strength of the valve body 101, but the through hole 107B on the annular protrusion 101e also ensures that the valve stem 103 can smoothly pass through it and achieve a stable connection with the pressing assembly 104. The second sealing ring 106 is sleeved around the circumference of the valve stem 103. This design allows the second sealing ring 106 to fit tightly against the gap between the valve stem 103 and the through hole 107B, effectively preventing fluid leakage from the through hole 107B to the pressing assembly 104. The high elasticity and wear resistance of the second sealing ring 106 enable it to maintain stable sealing performance during long-term use, providing strong support for the reliable operation of the mechanical valve 100. The pressure plate 107 is firmly connected to the annular protrusion 101e and tightly abuts against the second sealing ring 106. This design not only ensures that the second sealing ring 106 is securely fixed within the through hole 107B, preventing displacement or detachment under high pressure, but also further enhances the sealing effect between the second sealing ring 106 and the valve stem 103 and valve body 101 through the pressing action of the pressure plate 107. The introduction of the pressure plate 107 not only improves the sealing performance of the mechanical valve 100, but also provides a strong guarantee for its long-term stable operation.

[0082] Furthermore, the surface of the pressure plate 107 facing the annular protrusion 101e is provided with a groove 107A, and the annular protrusion 101e is engaged within the groove 107A. The introduction of the groove 107A makes the connection between the pressure plate 107 and the annular protrusion 101e more secure. When the pressure plate 107 is installed on the valve body 101, the annular protrusion 101e will naturally engage with the groove 107A, forming a tight and non-loose connection. This connection method not only simplifies the installation process and reduces the installation difficulty, but also improves the reliability and durability of the connection. At the same time, the design of the groove 107A also enhances the sealing performance of the mechanical valve 100. Since the annular protrusion 101e is firmly engaged within the groove 107A, the gap between it and the pressure plate 107 is effectively reduced, thereby reducing the possibility of fluid leakage from this gap. This design detail not only improves the sealing effect of the mechanical valve 100, but also provides strong protection for its stable operation in various harsh environments such as high pressure and high temperature.

[0083] Optionally, the pressing assembly 104 is snap-fitted into the valve body 101 and abuts against the side of the pressure plate 107 opposite to the annular protrusion 101e. This snap-fit ​​fixation makes the connection between the pressing assembly 104 and the valve body 101 more secure and reliable, forming a tight and non-loose connection. This connection method not only simplifies the assembly process and reduces assembly difficulty but also improves the overall strength and durability of the mechanical valve 100. Simultaneously, the pressing assembly 104 abutting against the side of the pressure plate 107 opposite to the annular protrusion 101e further enhances the sealing performance of the mechanical valve 100. Because a tight contact is formed between the pressing assembly 104 and the pressure plate 107, the gap between them is effectively reduced, thereby reducing the possibility of fluid leakage from this gap. This design detail not only improves the sealing effect of the mechanical valve 100 but also provides strong assurance for its stable operation in various harsh environments such as high pressure and high temperature.

[0084] Referring to Figures 6 and 7, in some embodiments, the valve body 101 includes a valve housing 1011 and an end cap 1012. The valve housing 1011 has a water outlet chamber 101B. The valve housing 1011 is connected to the end cap 1012 and forms a water inlet chamber 101A. The valve housing 1011 has a mounting portion 101a on the side facing the end cap 1012. A pressing assembly 104 is connected to the end of the valve housing 1011 away from the end cap 1012. The valve housing 1011 has a water outlet hole 101d communicating with the water outlet chamber 101B and a water inlet hole 101c communicating with the water inlet chamber 101A. The water outlet hole 101d and the water inlet hole 101c are located on the same side of the valve housing 1011.

[0085] It is understood that the valve housing 1011 has an open structure at both ends, and the button assembly and end cap 1012 connect to the valve body 101 and cover the open ends respectively. The end cap 1012 and the valve housing 1011 can be connected by a detachable method such as snaps or screws. The end cap 1012 and the valve housing 1011 together form the water inlet chamber 101A. In this way, during the assembly process, the first sealing ring 102 and spring 105 can be placed in the predetermined positions of the valve housing 1011 or the end cap 1012, and then the valve housing 1011 and the end cap 1012 can be tightly joined together. In this way, the first sealing ring 102 and spring 105 can be firmly fixed in the valve body 101, ensuring that they will not shift or fall off during operation, thereby ensuring the sealing performance and stability of the mechanical valve 100. When it is necessary to repair or replace components such as the first sealing ring 102 and the spring 105, the valve body 1011 can be separated from the end cover 1012, and then the components that need to be replaced can be easily removed for replacement or repair. In addition, the groove designed on the side of the end cover 1012 facing the valve body 101 is specifically designed to accommodate the spring 105. This attention to detail not only improves the utilization of the internal space of the valve body 101, but also further enhances the overall performance of the valve body 101. The outlet hole 101d and the inlet hole 101c are both located on the same side of the valve body 1011. This design makes it easier to connect the valve body 101 to the water circuit and reduces the difficulty of installation.

[0086] Referring to Figure 4, in some embodiments, the first mounting part 201 includes a frame 2011 and a connecting block 2012 connected to each other. The frame 2011 is connected to the second mounting part 202. The connecting block 2012 is provided with multiple snap-fit ​​ribs 201A, which together form a limiting groove 201B. The frame 2011, as the foundation of the entire first mounting part 201, bears the crucial responsibility of connecting to the second mounting part 202, ensuring a tight connection between the mounting part 101a and other parts of the system. The method of forming the limiting groove 201B through the snap-fit ​​ribs 201A of the connecting block 2012 is relatively simple and direct. This concise form not only reduces manufacturing costs but also allows the entire first mounting part 201 to maintain high strength while possessing a lighter appearance. The straight or curved shape of the snap-fit ​​ribs 201A is carefully selected according to actual needs, satisfying both structural strength requirements and facilitating processing and installation.

[0087] Furthermore, the connecting block 2012 has a first through hole 201C, and the first protrusion 108 has a first connecting hole 1081 corresponding to the first through hole 201C. The valve assembly 10 also includes a first fastener that passes through the first connecting hole 1081 and the first through hole 201C in sequence to fix the first protrusion 108 to the connecting block 2012. The first connecting hole 1081 and the first through hole 201C can be threaded holes, and the first fastener can be a screw. Using screws to further fix the first protrusion 108 to the connecting block 2012 not only further improves the stability of the mechanical valve 100 installation, but also simplifies the installation operation and facilitates disassembly for subsequent maintenance.

[0088] Referring to Figure 4, optionally, the first mounting part 201 further includes a support block 2013. The support block 2013 is connected to the frame 2011 and is located on the same side of the frame 2011 as the connecting block 2012. The support block 2013 abuts against a portion of the bottom surface of the valve body 101 of each mechanical valve 100. It should be noted that the support block 2013 can be an integral structure with the frame 2011 to ensure the structural strength of the support block 2013. The fact that the support block 2013 and the connecting block 2012 are located on the same side of the frame 2011 not only maintains the compactness of the structure but also ensures that the support block 2013 can fully exert its supporting function. Through the contact between the support block 2013 and the bottom surface of the valve body 101, the mechanical valve 100 receives additional support during installation. This support not only shares the pressure of the valve body 101 on the connecting block 2012 but also enhances the stability of the entire mounting structure. When the mechanical valve 100 is in operation, the presence of the support block 2013 can effectively prevent the valve body 101 from deforming or shifting due to uneven force, thereby ensuring the stability and reliability of the mechanical valve 100.

[0089] Furthermore, the support block 2013 has a second through hole 201a107B, and the mechanical valve 100 also includes a second protrusion 109. The second protrusion 109 is connected to the side of the valve body 101 opposite to the first protrusion 108. The second protrusion 109 has a second connecting hole 1091 corresponding to the second through hole 201a107B. The valve assembly 10 also includes a second fastener, which passes through the second connecting hole 1091 and the second through hole 201a107B in sequence to fix the second protrusion 109 to the connecting part. The second protrusion 109, like the first protrusion 108, can be integrally formed with the valve body 101 to ensure structural strength. Simultaneously, the second protrusion 109 is located on the opposite side of the valve body 101 from the first protrusion 108, forming a symmetrical layout to balance the fixing force of the mechanical valve 100. The second protrusion 109 is provided with a second connecting hole 1091 that matches the second through hole 201a 107B in the support block 2013. This corresponding design ensures that the two can be precisely connected. To securely connect the second protrusion 109 to the connecting part of the support block 2013, the valve assembly 10 is also equipped with a second fastener. During assembly, the second fastener is passed sequentially through the second connecting hole 1091 and the second through hole 201a 107B. Through the fastening action, the second protrusion 109 is effectively and tightly fixed to the connecting part, thereby improving the structural strength and stability of the mechanical valve 100. It should be noted that the second fastener can be the same as the first fastener, both being screws, and the second through hole 201a 107B and the second connecting hole 1091 are similarly screw holes.

[0090] Referring to Figure 4, optionally, the first mounting part 201 further includes a reinforcing rib 2014, which is connected to the frame 2011 and the support block 2013. The reinforcing rib 2014 effectively distributes the load borne by the frame 2011, reducing the risk of deformation or damage caused by external forces. Simultaneously, it more tightly connects the frame 2011 and the support block 2013 into a unified whole, improving the overall structural synergy and durability. Therefore, by introducing the reinforcing rib 2014, not only is the load-bearing capacity and deformation resistance of the frame 2011 improved, but the reliability and safety of the entire structure are further ensured.

[0091] Referring to Figure 4, in some embodiments, the inlet port 101c and outlet port 101d of each mechanical valve 100 are located on the same side of the valve support 200. This greatly simplifies the connection of subsequent water circuit components, reduces installation difficulty, and also reduces the potential leakage risk caused by the intricate water circuit components. Furthermore, this layout also improves fluid flow efficiency because the fluid flow path within the valve support 200 is more direct and smooth, reducing unnecessary detours and resistance. Moreover, from a maintenance perspective, the inlet port 101c and outlet port 101d on the same side facilitate inspection and maintenance by personnel, improving overall maintainability.

[0092] Furthermore, the valve assembly 10 also includes an inlet component 300, which includes a connected inlet 301 and at least two outlets 302. The inlet component 300 is connected to each mechanical valve 100, and each outlet 302 is connected to the inlet port 101c of a mechanical valve 100. This design allows the inlet component 300 to act as a central node for fluid distribution, effectively introducing fluid from a single inlet 301 and distributing it to multiple outlets 302. More importantly, a tight connection is established between the inlet component 300 and each mechanical valve 100, ensuring smooth fluid transmission. Specifically, each outlet 302 is directly connected to the inlet port 101c of a mechanical valve 100, thereby achieving precise distribution and transmission of fluid from the inlet component 300 to each mechanical valve 100. This design not only improves the efficiency of fluid transmission, but also ensures that each mechanical valve 100 can obtain the required fluid simultaneously and uniformly, thereby improving the working performance and reliability of the entire valve assembly 10.
