[0011] When the pressing assembly is in the first state, the sealing surface is spaced apart from the first sealing ring, so that the water inlet cavity and the water outlet cavity are in a conductive state; when the pressing assembly is in the second state, the sealing surface is in abutment with the first sealing ring, so that the water inlet cavity and the water outlet cavity are in a blocked state.

[0018] The second sealing ring is sleeved on the periphery of the valve rod, the pressing plate is connected with the annular protruding portion and is in abutment with the second sealing ring to be fixed in the through hole.

[0019] In some embodiments, the surface of the pressing plate facing the annular protruding portion is provided with a clamping groove, and the annular protruding portion is clamped in the clamping groove.

[0020] In some embodiments, the pressing assembly is clamped and fixed with the valve body and is in abutment with the side of the pressing plate away from the annular protruding portion.

[0021] In some embodiments, the valve body comprises a valve shell and an end cover, the valve shell is provided with the water outlet cavity, the valve shell is connected with the end cover and encloses the water inlet cavity, the valve shell is provided with the mounting portion on the side facing the end cover, and the pressing assembly is connected to the end of the valve shell away from the end cover;

In addition, in the movement process of the valve rod, the first sealing ring is always stably located in the mounting portion, and this design ensures the position stability of the first sealing ring, thereby ensuring the sealing effect. At the same time, since the water flow direction from the water inlet cavity to the water outlet cavity is consistent with the axial movement direction of the valve rod, and the elastic thrust provided by the spring is also in the same direction, this design effectively reduces the influence of the water flow pressure on the movement process of the mechanical valve, thereby significantly improving the pressure bearing capacity thereof.

[0036] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the accompanying drawings.

[0037] The following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] In the description of the present application, it is understood that the terms "first", "second" and the like are used only for the purpose of description, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0039] 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 the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more associated listed items.

[0040] The first aspect of the present application proposes a drinking water equipment, which can be a water purifier or a purified drinking machine, etc. The core function of the drinking water equipment is to provide clean drinking water to meet the daily drinking water needs of users. In terms of water supply, the drinking water equipment shows high flexibility. It can be connected with a barrel of water to supply drinking water to users by using the barrel of water as a water source. At the same time, it can also be directly connected with a tap to use tap water as a water source. The drinking water equipment can be connected with a barrel of water or a tap to realize water supply.

[0041] In the related art field, in order to ensure the effective on-off control of water flow, the drinking water equipment usually needs to be equipped with a mechanical valve, which usually adopts a rotary knob structure. However, this rotary knob mechanical valve not only has a relatively complex structure, but also needs to exert a relatively large force when rotating, which leads to an unsmooth operation process and affects the user's experience.

[0042] To solve the above problems, please refer to Figures 1 to 3 The second aspect of the present application proposes a mechanical valve 100. In the embodiments of the present application, the mechanical valve 100 includes a valve body 101, a first sealing ring 102, a valve rod 103, a pressing assembly 104 and a spring 105.

[0043] The valve body 101 has a water inlet cavity 101A and a water outlet cavity 101B, and a communication port 101C that connects the water inlet cavity 101A and the water outlet cavity 101B. The valve body 101 includes a mounting portion 101a located within the water inlet cavity 101A. It can be understood that the water inlet cavity 101A is responsible for receiving input from external fluids, while the water outlet cavity 101B is responsible for outputting fluids to the next link. This design ensures the orderly flow of fluids within the valve body 101. It should be noted that the flow area of the water inlet cavity 101A is designed to be larger than that of the water outlet cavity 101B, so as to achieve throttling and pressure reduction effects. When the 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 can help regulate and control the flow and pressure of the fluid, thereby achieving more precise and stable fluid control. The opening shape of the communication port 101C can be a regular shape such as a circle or a square, to facilitate processing and manufacturing.

[0044] The first sealing ring 102 is connected to the mounting portion 101a and is arranged around the communication port 101C. The first sealing ring 102 can be made of materials such as silicone or rubber, so that the first sealing ring 102 has excellent corrosion resistance, tear resistance, and compression deformation resistance.

[0045] The valve stem 103 is movably arranged in the valve body 101 and at least partially located in the water inlet cavity 101A and the water outlet cavity 101B. The portion of the valve stem 103 located in the water inlet cavity 101A has a sealing surface 103A facing the first sealing ring 102. The specific movement of the valve stem 103 is sliding along the arrangement direction of the water inlet cavity 101A and the water outlet cavity 101B. This sliding movement enables the valve stem 103 to accurately control the on-off of the fluid 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 material. Plastic material has the advantages of light weight, corrosion resistance, easy processing, etc., and can meet the use requirements of the mechanical valve 100 in different working environments. In addition, the plastic material valve stem 103 also has good wear resistance and anti-aging performance, which can prolong the service life of the mechanical valve 100.

[0046] The pressing assembly 104 is connected to the valve body 101 and the valve stem 103, wherein one end of the pressing assembly 104 is provided with a mounting hole, and one end of the valve stem 103 is inserted into the mounting hole, so that the pressing assembly 104 drives the valve stem 103 to move along the axial direction of itself and switch to the first state or the second state. It should be noted that the structure of the pressing assembly 104 is borrowed from the existing technology of the pressing type ballpoint pen and similar designs. These designs usually include a mechanism of self-locking structure such as a ratchet to ensure the stability and reliability of the pressing action. In the ballpoint pen, the tail of the pen is provided with such a pressing assembly 104, when the user presses the tail of the pen, the ratchet structure drives the ink cartridge to move downward and self-lock, so that the ink cartridge is in the state of extending and writing. When the user presses the tail of the pen again, the ratchet structure moves in the opposite direction, so that the ink cartridge is withdrawn into the pen barrel and is in the state of not writing. The structure of the pressing assembly 104 of the existing technology is applied to the mechanical water valve, which can realize similar functions. The user only needs to press the pressing assembly 104 gently, which drives the valve stem 103 to move, so as to change the state of the mechanical valve 100. This design not only improves the operation convenience of the mechanical valve 100, but also ensures the stability and reliability thereof.

[0047] The spring 105 is arranged in the water inlet cavity 101A, and the two ends of the spring 105 respectively abut against the valve stem 103 and the cavity wall of the water inlet cavity 101A, and provide a pushing force acting on the valve stem 103 and along the axial direction of the valve stem 103 towards the pressing assembly 104. Wherein, when the pressing assembly 104 is in the first state, the sealing surface 103A is arranged in a spaced manner with the first sealing ring 102, so as to make the water inlet cavity 101A and the water outlet cavity 101B in a conductive state, and when the pressing assembly 104 is in the second state, the sealing surface 103A is arranged in abutment with the first sealing ring 102, so as to make the water inlet cavity 101A and the water outlet cavity 101B in a blocked state.

[0048] The mechanical valve 100 of the embodiment of the present application is applied to a water drinking device, and comprises a valve body 101, a first sealing ring 102, a valve rod 103, a pressing assembly 104 and a spring 105. In actual operation, a user drives the valve rod 103 to move along the axial direction between a water inlet cavity 101A and a water outlet cavity 101B of the valve body 101 by operating the pressing assembly 104, so as to realize the on-off control of the water inlet cavity 101A and the water outlet cavity 101B. Specifically, when the pressing assembly 104 is pressed for the first time and is in a first state, it drives the valve rod 103 to move along the axial direction, in this process, the spring 105 is moderately compressed, and at the same time, a sealing surface 103A on the valve rod 103 keeps a certain interval with the first sealing ring 102, so as to ensure the smooth conduction between the water inlet cavity 101A and the water outlet cavity 101B, and allow the water flow to pass freely. When the pressing assembly 104 is pressed again, so that the pressing assembly 104 enters a second state, at this time, the spring 105 pushes the valve rod 103 to move reversely by using the reset thrust, at this time, the sealing surface 103A tightly abuts on the first sealing ring 102, effectively cutting off the water inlet cavity 101A and the water outlet cavity 101B, and realizing the complete cut-off of the water flow.

[0049] The design of the mechanical valve 100 not only has simple structure and low manufacturing cost, but also greatly simplifies the structure of the mechanical valve 100 while realizing the effective control of the water flow, and improves the operation convenience. In addition, in the movement process of the valve rod 103, the first sealing ring 102 is always stably located in the installation part 101a, and this design ensures the position stability of the first sealing ring 102, so as to ensure the sealing effect. At the same time, since the water flow direction of the water inlet cavity 101A to the water outlet cavity 101B is consistent with the axial movement direction of the valve rod 103, and the elastic thrust provided by the spring 105 is also in the same direction, this design effectively reduces the influence of the water flow pressure on the movement process of the mechanical valve 100, so as to significantly improve the pressure bearing capacity.

[0050] Reference Figures 2 to 4In some structural forms, the mounting portion 101a includes a cavity wall surface of the water inlet cavity 101A, which is oppositely arranged with the sealing surface 103A and recessed to form a limiting groove 101b, and the first sealing ring 102 is embedded in the limiting groove 101b and at least partially protrudes out of the limiting groove 101b. In this way, by forming the limiting groove 101b, a stable support and positioning point is provided for the first sealing ring 102, and the stability and accuracy of the sealing ring after installation are also ensured. When the valve rod 103 moves under the drive of the pressing assembly 104, the contact between the sealing surface 103A and the first sealing ring 102 becomes more close and reliable. The presence of the limiting groove 101b not only prevents the 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 prolongs the service life of the sealing ring, thereby reducing maintenance costs and replacement frequency. Of course, in other embodiments, the mounting portion 101a can also be a sleeve structure arranged directly on the cavity wall of the water inlet cavity 101A. This design enables the first sealing ring 102 to be directly sleeved on 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.

[0051] Optionally, the sealing surface 103A is arranged in a plane. In this way, the planar sealing surface 103A can provide a more uniform and stable contact area. When the valve rod 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 can ensure that the contact pressure between the two is evenly distributed, thereby effectively preventing fluid from leaking around the sealing surface 103A. Secondly, the planar sealing surface 103A is relatively simple to process and manufacture, which helps to reduce production costs and improve production efficiency. The planar shape is easy to accurately manufacture through mechanical processing or mold forming, etc., thereby ensuring that the sealing surface 103A of each water valve is consistent and reliable.

[0052] Referring to Figure 3 In some structural forms, the valve rod 103 includes a rod body portion 1031 and a sealing portion 1032 arranged around the rod body portion 1031, the peripheral wall of the rod body portion 1031 is arranged spaced apart from the cavity wall of the water inlet cavity 101A and the water outlet cavity 101B, the rod body portion 1031 is connected with the pressing assembly 104, the sealing portion 1032 is located in the water inlet cavity 101A, the sealing portion 1032 abuts against the spring 105, and the surface of the sealing portion 1032 facing away from the spring 105 is the sealing surface 103A.

[0053] The rod body part 1031 serves as the main structure of the valve rod 103, and its peripheral wall is kept at a certain interval from the cavity wall of the water inlet cavity 101A and the water outlet cavity 101B. This design not only avoids direct friction between the rod body part 1031 and the cavity wall, reducing wear and energy consumption, but also provides a smooth channel for fluid flow between the water inlet cavity 101A and the water outlet cavity 101B.

[0054] The sealing part 1032, as a key component of the valve rod 103, is located in the water inlet cavity 101A and abuts against the spring 105. It should be noted that the side of the sealing part 1032 away from the sealing surface 103A forms a stepped surface, which not only provides a stable support point for the spring 105, but also makes the fixation of the spring 105 more secure and reliable. The surface of the sealing part 1032 away from the spring 105 is designed as the sealing surface 103A, which, when in contact with the first sealing ring 102 and the sealing surface 103A covers the communication port 101C, can generate sufficient sealing pressure to ensure that fluid does not leak from the sealing surface 103A. In addition, the ring structure of the sealing part 1032 not only enhances the overall stability of the valve rod 103, but also allows the sealing surface 103A to be evenly distributed around the peripheral side of the rod body part 1031, thereby improving the reliability and durability of the seal. When the valve rod 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.

[0055] Further, along the axial direction of the rod body part 1031, the projection of the sealing part 1032 covers the first sealing ring 102. First, this covering design ensures that the contact area between the sealing part 1032 and the first sealing ring 102 is maximized. When the valve rod 103 moves under the drive of the pressing assembly 104, the sealing part 1032 can tightly adhere to 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, so that the mechanical valve 100 can maintain stable sealing effect in high-pressure environment. Second, this design helps to reduce the risk of fluid leakage. Since the projection of the sealing part 1032 completely covers the first sealing ring 102, even under adverse conditions such as long-term operation of the mechanical valve 100 or external impact, it can effectively prevent fluid from leaking from the small gap between the sealing surface 103A and the first sealing ring 102. This not only improves the sealing performance of the mechanical valve 100, but also prolongs its service life, reduces maintenance costs and downtime due to leakage.

[0056] In combination with reference Figure 5In some structural forms, the first sealing ring 102 is provided with an annular protrusion 1021 on the side close to the sealing surface 103A, and the annular protrusion 1021 is arranged around the communication port 101C. In this way, when the first sealing ring 102 is in contact with the sealing surface 103A, the annular protrusion 1021 can effectively block the leakage of fluid like a barrier. The presence of the annular protrusion 1021 actually converts the traditional face seal into a more efficient line seal. Compared with face seal, line seal can provide more concentrated sealing pressure. Since the annular protrusion 1021 is arranged around the communication port 101C, when the first sealing ring 102 is under pressure, the annular protrusion 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 caused by uneven or worn sealing surface 103A. In addition, the design of the annular protrusion 1021 also enhances the durability of the first sealing ring 102. In the long-term use process, even if the sealing surface 103A is worn to a certain extent, the annular protrusion 1021 can still maintain its structural integrity and continue to provide effective sealing. This design not only prolongs the service life of the first sealing ring 102, but also reduces the maintenance cost caused by seal failure.

[0057] In combination with reference to Figure 2 , Figure 3 and Figure 6 In some structural forms, the mechanical valve 100 further comprises a second sealing ring 106 and a pressing plate 107. The valve body 101 is provided with an annular protrusion 101e on the side close to the pressing assembly 104, and the annular protrusion 101e is provided with a through hole 107B communicating with the water outlet cavity 101B. The valve rod 103 is at least partially arranged through the through hole 107B and connected with the pressing assembly 104. The second sealing ring 106 is sleeved on the peripheral side of the valve rod 103, the pressing plate 107 is connected with the annular protrusion 101e and abuts against the second sealing ring 106 to be fixed in the through hole 107B.

[0058] The structure of the annular protrusion 101e not only enhances the overall strength of the valve body 101, but also the through hole 107B opened on the annular protrusion 101e to ensure that the valve rod 103 can be smoothly threaded therein and stably connected with the pressing assembly 104. The second sealing ring 106 is sleeved on the peripheral side of the valve rod 103, which makes the second sealing ring 106 closely fit on the gap between the valve rod 103 and the through hole 107B, thereby effectively preventing the fluid from leaking 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 pressing plate 107 is firmly connected with the annular protrusion 101e and closely abuts against the second sealing ring 106. This design not only ensures that the second sealing ring 106 can be stably fixed in the through hole 107B to prevent it from being displaced or falling off under high pressure, but also further enhances the sealing effect between the second sealing ring 106 and the valve rod 103 and the valve body 101 through the pressing action of the pressing plate 107. The introduction of the pressing plate 107 not only improves the sealing performance of the mechanical valve 100, but also provides strong guarantee for its long-term stable operation.

[0059] Further, the surface of the pressing plate 107 facing the annular protrusion 101e is provided with a clamping groove 107A, and the annular protrusion 101e is clamped in the clamping groove 107A. The introduction of the clamping groove 107A makes the connection between the pressing plate 107 and the annular protrusion 101e more firm. When the pressing plate 107 is installed on the valve body 101, the annular protrusion 101e will naturally be clamped into the clamping groove 107A to form a tight and not easy to loosen 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 clamping groove 107A also enhances the sealing performance of the mechanical valve 100. Since the annular protrusion 101e is firmly clamped in the clamping groove 107A, the gap between it and the pressing 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 guarantee for its stable operation in various harsh environments such as high pressure and high temperature.

[0060] Optionally, the pressing assembly 104 is clamped and fixed with the valve body 101, and abuts against the side of the pressing plate 107 away from the annular protrusion 101e. The introduction of clamping and fixing makes the connection between the pressing assembly 104 and the valve body 101 more firm and reliable. A tight and not easy to loosen connection is formed. This connection method not only simplifies the assembly process, reduces the assembly difficulty, but also improves the overall strength and durability of the mechanical valve 100. At the same time, the pressing assembly 104 abuts against the side of the pressing plate 107 away from the annular protrusion 101e, which further enhances the sealing performance of the mechanical valve 100. Since the pressing assembly 104 and the pressing plate 107 form a tight contact, the gap between them is effectively reduced, thereby reducing the possibility of fluid leakage from the gap. This design detail not only improves the sealing effect of the mechanical valve 100, but also provides a strong guarantee for its stable operation in various harsh environments such as high pressure and high temperature.

[0061] With reference to Figure 3 and Figure 4 In some embodiments, the valve body 101 includes a valve shell 1011 and an end cover 1012, the valve shell 1011 is provided with a water outlet cavity 101B, the valve shell 1011 is connected with the end cover 1012 and encloses to form a water inlet cavity 101A, the valve shell 1011 is provided with a mounting portion 101a on the side facing the end cover 1012, and the pressing assembly 104 is connected to the end of the valve shell 1011 away from the end cover 1012. The valve shell 1011 is provided with a water outlet hole 101d communicating with the water outlet cavity 101B and a water inlet hole 101c communicating with the water inlet cavity 101A, and the water outlet hole 101d and the water inlet hole 101c are located on the same side of the valve shell 1011.

[0062] It can be understood that the valve shell 1011 is specifically an open-ended structure, and the button assembly and the end cover 1012 are connected to the valve body 101 and cover the two open ends respectively. The end cover 1012 and the valve shell 1011 can be connected by buckling or screwing or the like, and the end cover 1012 and the valve shell 1011 together form a water inlet cavity 101A. In this way, during assembly, the first sealing ring 102, the spring 105 and the like can be placed in the predetermined position of the valve shell 1011 or the end cover 1012, and then the valve shell 1011 and the end cover 1012 are tightly combined together. In this way, the first sealing ring 102, the spring 105 and the like can be firmly fixed in the valve body 101, so as to ensure that they will not be displaced or fall off during operation, thereby ensuring the sealing performance and stability of the mechanical valve 100. When the first sealing ring 102, the spring 105 and the like need to be repaired or replaced, the valve shell 1011 and the end cover 1012 can be separated, and then the components to be replaced or repaired can be conveniently taken out for replacement or repair. In addition, the groove designed on the side of the end cover 1012 towards the valve body 101 is specially used for accommodating the spring 105. Such a detail processing not only improves the utilization rate of the internal space of the valve body 101, but also further enhances the overall performance of the valve body 101. The water outlet hole 101d and the water inlet hole 101c are located on the same side of the valve shell 1011. This design makes the valve body 101 more convenient to connect with the waterway in the subsequent process, and reduces the installation difficulty.
