[0047] Water purifiers and other drinking water equipment have become indispensable household items in daily life and workplaces, such as homes and offices. These devices, connected to direct drinking water sources like tap water, provide users with convenient and quick drinking water services, significantly improving the comfort and convenience of life.

[0048] In the relevant technical field, drinking water equipment is equipped with filter cartridges to remove impurities, residual chlorine, heavy metals, bacteria, and other harmful substances from the water, ensuring the purity and safety of the output water. However, in actual operation, the installation location of the filter cartridge is usually concealed and space is limited, making it difficult for users to install and remove it, especially without sufficient guidance or with unclear instructions. This not only increases the difficulty of operation for users but may also affect the filtration effect of the filter cartridge due to improper installation, and even lead to safety hazards such as equipment leakage.

[0049] To address the aforementioned issues, please refer to Figures 1 to 3. This application proposes a drinking water device 1, which can be a water purifier or a water dispenser, etc. Its 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 1 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. In the embodiments of this application, the drinking water device 1 includes a housing assembly 20, a water circuit assembly 30, and a filter element 40.

[0050] The housing assembly 20 has a mounting cavity 221 extending in the vertical direction, and the top wall of the housing assembly 20 has a mounting port 211 communicating with the mounting cavity 221. The water channel assembly 30 is disposed in the housing assembly 20 and is at least partially located in the mounting cavity 221.

[0051] The housing assembly 20, as the main structure of the drinking water device 1, not only plays a vital role in supporting and protecting the internal components but also ensures the overall aesthetics and durability of the device. The water circuit assembly 30, on the other hand, is the core component for realizing the water supply function. It includes various necessary water pipes and connectors to ensure smooth and stable water flow. It should be noted that the opening of the mounting port 211 can be a regular shape such as round or square for ease of processing.

[0052] The filter element 40 is installed in the mounting cavity 221 through the mounting port 211 and communicates with the portion of the water circuit assembly 30 located in the mounting cavity 221. The filter element 40 includes a PAC filter element 40, an activated carbon filter element 40, a nanofiltration membrane filter element 40, and a post-filter element 40 connected in series along the water flow direction. This allows for multiple filtration of the water flow, thereby improving the quality of the effluent. Furthermore, a handle 43 can be provided at the top of the filter element 40 for easy gripping by the user, facilitating subsequent replacement.

[0053] In the drinking water device 1 of this application embodiment, an installation port 211 is provided on the top wall of the housing, connecting to the installation cavity 221 extending vertically. This design allows the filter element 40 to directly pass through the installation port 211 from the top and enter the installation cavity 221, thus communicating with the portion of the water circuit assembly 30 located within the installation cavity 221. This improvement greatly simplifies the installation process of the filter element 40. Users no longer need to operate with difficulty in a narrow space; instead, they can easily install and remove the filter element 40 through the top installation port 211. This not only improves the convenience of installation and reduces the difficulty of operation for users, but also ensures that the filter element 40 can be correctly and firmly installed in place, thereby fully exerting its filtration function and ensuring the purity and safety of the output water. At the same time, the simplified installation process also reduces safety hazards such as equipment leakage caused by improper installation, improving the overall performance of the drinking water device 1.

[0054] Referring to Figures 1 to 3, in some embodiments, the housing assembly 20 includes an outer shell 21 and a mounting bracket 22. The water channel assembly 30 is disposed inside the outer shell 21. The top wall of the outer shell 21 has a mounting opening 211. The mounting bracket 22 is fixed inside the outer shell 21 and located below the mounting opening 211, forming a mounting cavity 221. The outer shell 21 may include a chassis 216, a middle shell 214, a front panel 213, and a rear panel 215. The middle shell 214, front panel 213, and rear panel 215 are all connected to the chassis 216. The front panel 213 and rear panel 215 are respectively connected to the two ends of the middle shell 214 in the front-rear direction, thereby enclosing and forming the outer contour of the entire machine. The top wall of the middle shell 214 has a mounting opening 211. The mounting bracket 22 can be fixed to the chassis 216 by screws or clips. The water circuit assembly 30 includes a connecting base 31 connected to the bottom of the mounting bracket 22. The connecting base 31 has a fixing groove 311 communicating with the bottom of the mounting cavity 221. The end of the filter element 40 is accommodated in the fixing groove 311 and communicates with the connecting base 31. The connecting base 31 is tightly connected to the bottom of the mounting cavity 221, so that after the filter element 40 extends into the mounting cavity 221 through the mounting port 211, under the action of gravity, the end of the filter element 40 will fall directly into the fixing groove 311 of the connecting base 31 and communicate with the connecting base 31. This design not only greatly improves the installation stability of the filter element 40 and avoids shaking and displacement of the filter element 40 during use, but also ensures that the water flow remains smooth and efficient when passing through the filter element 40. The tight fit between the fixing groove 311 and the end of the filter element 40 prevents water leakage and ensures that the filter element 40 can fully exert its filtration function, providing users with purer and healthier drinking water. It should be noted that the connecting base 31 can be fixed to the mounting bracket 22 by the connecting kit 70. The connecting kit 70 is sleeved and fixed to the outer peripheral wall of the connecting base 31, and then the connecting kit 70 can be fixed to the mounting bracket 22 by screws or buckles.

[0055] Referring to Figures 4 and 5, further, the bottom surface of the fixing groove 311 is provided with a first connecting part (not shown), and the end face of the filter element 40 is provided with a first fixing part 41 corresponding to the first connecting part. The first fixing part 41 and the first connecting part are engaged. This engagement method is not only simple and easy to implement, but also ensures the stability and firmness of the filter element 40 after installation. Specifically, the first connecting part and the first fixing part 41 can adopt a combination of a plug and a slot. The plug, as the specific form of the first connecting part, has a shape and size that closely matches the slot (i.e., the first fixing part 41). When the filter element 40 is inserted into the mounting opening 211 and falls into the fixing groove 311, the plug will accurately insert into the slot, and the tight fit between the two achieves radial positioning of the filter element 40. This plug-and-slot engagement method not only improves the installation efficiency of the filter element 40, but also greatly enhances the connection strength between the filter element 40 and the connecting base 31. During equipment operation, even if the water flow exerts a certain impact force on the filter element 40, the filter element 40 remains firmly fixed within the fixing groove 311 without loosening or displacement. Furthermore, the fit between the insert and the slot provides excellent sealing performance. When the insert is fully inserted into the slot, a tight sealing surface 103A is formed between them, effectively preventing water leakage and the intrusion of external impurities. This not only ensures the normal operation of the equipment but also extends the service life of the filter element 40, providing users with purer and healthier drinking water.

[0056] Optionally, the sidewall of the fixing groove 311 is provided with a second connecting part (not shown), and the sidewall of the filter element 40 is provided with a second fixing part 42 corresponding to the second connecting part. The second fixing part 42 and the second connecting part are engaged in a snap-fit ​​connection. The presence of these two parts allows the filter element 40 to achieve a more stable connection during installation through a snap-fit ​​connection. Specifically, the engagement between the second fixing part 42 and the second connecting part is not a simple insertion or push-pull, but a more ingenious rotational engagement. This engagement method requires the filter element 40 to be rotated in a specific direction during installation so that the second fixing part 42 can be accurately aligned with the second connecting part and snapped in. Once the engagement is successful, the filter element 40 can achieve stable positioning in the axial direction, avoiding shaking and displacement caused by water flow impact or external forces. The rotational engagement method not only improves the installation stability of the filter element 40, but also makes the disassembly process of the filter element 40 easier. When the user needs to replace the filter element 40, simply rotate the filter element 40 in the opposite direction to easily disengage the second fixing part 42 from the second connecting part, thus achieving quick replacement of the filter element 40. Furthermore, the rotational engagement mechanism also has a self-locking function. When the filter element 40 is rotated to the correct position and successfully engaged, the second fixing part 42 and the second connecting part will form an interlocking state, which effectively prevents the filter element 40 from accidentally falling off or loosening during use.

[0057] In summary, the first connecting part, the second connecting part, the first fixing part 41, and the second fixing part 42 can be provided simultaneously to achieve axial and radial fixation of the filter element 40 after installation, and also enhance the safety and reliability of the filter element 40 during use.

[0058] Referring to Figures 2 and 3, in some embodiments, the length extension direction of the mounting cavity 221 is perpendicular to the horizontal direction. From a space utilization perspective, the vertically arranged mounting cavity 221 can make more efficient use of vertical space, especially in space-constrained installation environments. This design can significantly save floor space, allowing the equipment to adapt more flexibly to various installation scenarios. Simultaneously, the vertical layout also makes the filter element 40 more intuitively visible to the operator during installation and replacement, facilitating related operations and maintenance. Furthermore, the vertically arranged mounting cavity 221 also helps improve the overall stability of the equipment. Since the filter element 40 is installed vertically, its gravity direction is consistent with the extension direction of the mounting cavity 221, which allows the filter element 40 to be more firmly fixed in the fixing groove 311 after installation, avoiding shaking or displacement caused by inconsistent gravity directions. This stability not only ensures the normal operation of the equipment but also extends the service life of the filter element 40.

[0059] Referring to Figures 1 to 3, optionally, the housing assembly 20 also includes a top cover 23, which is detachably connected to the top of the housing 21 and covers the mounting port 211. The presence of the top cover 23 provides an extra layer of protection for the device. It effectively blocks the mounting port 211, preventing external factors such as dust, debris, or moisture from entering the water supply device 1 and damaging critical components such as the water circuit assembly 30 and the filter element 40. Secondly, the detachable connection of the top cover 23 also considers ease of use. When the user needs to install or replace the filter element 40, they can easily access the mounting port 211 by simply opening the top cover 23. This design not only simplifies the operation process but also makes it easier for users to maintain and care for the device. Furthermore, the top cover 23 is tightly connected to the top of the housing 21, forming an integrated appearance.

[0060] Referring to Figures 1 to 3, optionally, a viewing window 212 is provided on the front side of the housing 21, and a transparent area 222 is provided on the side of the mounting bracket 22 near the viewing window 212, opposite to the viewing window 212. The transparent area 222 is used to display the filter element 40. The viewing window 212 can be made of a light-transmitting material such as glass. The presence of the transparent area 222 of the mounting bracket 22 allows the user to clearly observe the status of the filter element 40 through the viewing window 212 of the housing 21. This design meets the user's need for real-time monitoring of the status of the filter element 40. During daily use, the user can intuitively see the cleanliness and remaining service life of the filter element 40 without disassembling the housing 21 or the top cover 23. This visual management method not only allows the user to have a clear understanding of the status of the filter element 40, but also promptly reminds the user to replace the filter element 40, thereby ensuring that the device always maintains the best filtration effect.

[0061] Referring to Figure 2, in some embodiments, the drinking water device 1 further includes an ice tank 50 and a valve assembly 10. The valve assembly 10 and the ice tank 50 are disposed within the housing assembly 20. The valve assembly 10 is connected to both the ice tank 50 and the filter element 40 via a water passage assembly 30. The ice tank 50 is used to cool the water. The ice tank 50 and the valve assembly 10 are carefully positioned inside the housing assembly 20, and they are efficiently connected via a precision water passage assembly 30. The valve assembly 10 is tightly connected to the filter element 40, ensuring that the water purified by the filter element 40 flows smoothly through the valve assembly 10, is cooled by the ice tank 50, and then discharged for the user to drink. The presence of the ice tank 50 allows the device to not only provide purified water but also to provide refreshing cold water according to the user's needs, greatly enhancing the user experience.

[0062] In addition, the water dispenser 1 is equipped with a control component 60, which makes the device more intelligent. The control component 60 is electrically connected to the ice tank 50, allowing users to precisely control the cooling efficiency of the ice tank 50. This means users can adjust the temperature of the cold water at any time according to their preferences and needs, thus obtaining the best drinking experience. Simultaneously, the control component 60 can monitor the working status of the ice tank 50 in real time, ensuring that it maintains a stable cooling effect while operating efficiently. This highly integrated design not only greatly enhances the functionality of the device but also makes its overall structure more compact and rational. The ingenious combination of the ice tank 50, valve assembly 10, control component 60, and housing assembly 20 forms a highly efficient, stable, and intelligent water dispenser system. Users can enjoy the convenient integrated purification and cooling service simply by operating the control component 60, thus meeting various daily drinking and cooling needs.

[0063] Referring to Figures 6 to 9, in some embodiments, the valve assembly 10 includes at least two mechanical valves 100 and a valve bracket 200. The valve bracket 200 is used to connect to the housing assembly 20, and the valve bracket 200 includes a first mounting portion 201 and a second mounting portion 202 connected to each other. It should be noted that, from the perspective of structural strength, the first mounting portion 201 and the second mounting portion 202 can be designed as an integral structure. This design ensures that the overall structure of the valve bracket 200 is robust and stable, and can withstand greater external forces without easily being damaged. However, for maintainability, the first mounting portion 201 and the second mounting portion 202 can also be connected by 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 fails or needs to be upgraded, it can be easily disassembled without replacing the entire valve bracket 200, thereby reducing maintenance costs. When connecting to the housing assembly 20, either the first mounting portion 201 or the second mounting portion 202 of the valve bracket 200 is connected to the housing assembly 20 to achieve basic connection and fixation. This design satisfies basic connection requirements while ensuring connection stability. Furthermore, to further improve connection stability, both the first mounting portion 201 and the second mounting portion 202 can be connected to the housing assembly 20 simultaneously. This dual connection significantly enhances the connection strength between the valve assembly 10 and the housing assembly 20, ensuring stable operation in various complex working environments.

[0064] 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 the water circuit assembly 30. 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 device 1 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.

[0065] By including at least two mechanical valves 100 and a valve bracket 200 in the valve assembly 10, with the valve bracket 200 comprising a first mounting portion 201 and a second mounting portion 202, and each mechanical valve 100 mounted on the first mounting portion 201, multiple mechanical valves 100 are integrated. This integrated design not only facilitates subsequent modular assembly but also significantly improves space utilization and assembly efficiency, resulting in a neater and more orderly internal structure for the drinking water equipment 1. Simultaneously, the second mounting portion 202 includes a water pipe 2023 and is equipped with an inlet 2021 and an outlet 2022 connected to the water pipe 2023, forming a water passage on the valve bracket 200. This reduces the need for additional water passage components, lowers installation difficulty, and makes the overall valve assembly 10 more compact and easier to install, while also making subsequent maintenance more efficient and convenient.

[0066] Referring to Figures 6 and 9, 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 practical 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.

[0067] Furthermore, referring to Figures 10 to 12, in some embodiments, 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 connecting 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 is responsible for receiving the input fluid from the outside, while the outlet chamber 101B is responsible for outputting the fluid to the next stage. This design ensures the orderly flow of fluid within the valve body 101. It should be noted that the flow area of ​​the inlet chamber 101A is designed to be larger than the flow area of ​​the outlet chamber 101B, thus achieving the effects of throttling and pressure reduction. When fluid passes through the valve body 101, the flow rate and pressure of the fluid will 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.

[0068] 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.

[0069] 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.

[0070] In some structural configurations, referring to Figure 14, 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 beyond it. This limiting groove 101b provides a stable support and positioning point for the first sealing ring 102, ensuring its stability and accuracy 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.

[0071] 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.

[0072] Referring to Figure 12, in some structural forms, the push rod includes a rod body 1031 and a sealing part 1032 arranged around the periphery of the rod body 1031. The periphery 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.

[0073] The rod body 1031 serves as the main structure of the push rod, and its peripheral wall maintains 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.

[0074] The sealing part 1032, as a key component of the push rod, is located within the water 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 the sealing surface 103A. When this surface contacts the first sealing ring 102, and the sealing surface 103A covers the connecting port 101C, it can generate sufficient sealing pressure to ensure that fluid does not leak from the sealing surface 103A. Furthermore, the circumferential 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.

[0075] 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.

[0076] Referring to Figure 13, 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.

[0077] Referring to Figures 11, 12, and 15, 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Referring to Figures 11 and 12, 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.

[0082] 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.

[0083] Referring to Figure 9, 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.

[0084] 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.

[0085] Referring to Figure 9, 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.

[0086] Furthermore, the support block 2013 has a second through hole 201a, 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 201a. The valve assembly 10 also includes a second fastener, which passes through the second connecting hole 1091 and the second through hole 201a 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 has a second connecting hole 1091 that matches the second through hole 201a in the support block 2013; this corresponding design ensures precise docking between the two. To securely connect the second protrusion 109 to the connecting portion 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, effectively and tightly fixing the second protrusion 109 to the connecting portion through a fastening action, 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, which is a screw, and the second through hole 201a and the second connecting hole 1091 are similarly screw holes.

[0087] Referring to Figure 9, 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.

[0088] Referring to Figure 9, in some embodiments, the inlet ports 101c and outlet ports 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 30, reduces installation difficulty, and also reduces the potential leakage risk caused by the intricate water circuit components 30. 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 ports 101c and outlet ports 101d on the same side facilitate inspection and maintenance by personnel, improving overall maintainability.

[0089] 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.
