Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, and in particular to a one-way valve assembly and a water purifier structure having the same. Background Technology

[0002] As a key component for controlling the unidirectional flow of fluid, the check valve is widely used in many fields such as hydraulic systems, pneumatic systems, medical devices, water supply and drainage equipment, and daily chemical products. Its core function is to ensure that the fluid can only flow in a preset direction, while preventing the fluid from flowing back in the opposite direction, thereby ensuring the normal operation logic and working stability of the entire system.

[0003] In existing technologies, to achieve good sealing and low opening pressure, some check valves use flexible materials for their valve bodies. These flexible materials utilize their deformation properties to open or close the valve port under fluid pressure. However, flexible materials themselves have low structural strength. Under large fluid pressure fluctuations or during long-term use, the valve body sidewalls are prone to irregular deformation or even collapse, leading to poor valve opening, unstable flow, and in severe cases, reverse leakage. This significantly affects the reliability and service life of the check valve. Furthermore, in many applications, the fluid may contain impurities, particles, and other foreign matter. If these foreign objects enter the check valve, they can not only clog the valve port and cause failure, but also damage downstream system components through wear and scratches, increasing equipment maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a one-way valve assembly and a water purifier structure having the same, aiming to solve at least one of the technical problems existing in the prior art.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a one-way valve assembly and a water purifier structure having the same, comprising:

[0007] A support structure, made of rigid material, is installed inside the one-way valve body. The support structure includes a support portion, the surface of which is uniformly provided with a plurality of filter holes for filtering liquid flowing from the open end to the slit end. The support portion is disposed inside the open end and is capable of supporting the inner wall of the one-way valve body.

[0008] Furthermore, the outer contour shape of the support portion is adapted to the inner cavity wall shape of the one-way valve body; or

[0011] Furthermore, the support structure also includes a flange structure, and the flange structure extends radially outward along the support portion. The opening end of the one-way valve is provided with a sealing skirt, which covers or presses against the flange structure.

[0012] Furthermore, the inner surface of the sealing skirt is recessed outward in a radial direction to form an assembly groove, which is correspondingly provided with the flange structure so that when the support structure is installed in the one-way valve body, the flange structure can be at least partially embedded in the assembly groove.

[0013] Furthermore, it also includes: a first housing and a second housing, the first housing and the second housing being used to clamp the flange structure, thereby limiting the axial displacement of the support structure and the one-way valve body;

[0014] The outer diameter of the flange structure is larger than the inner diameter of the first housing, and the outer diameter of the flange structure is larger than the inner diameter of the second housing, so that the first housing and the second housing can clamp the flange structure and the sealing skirt together to prevent the flange structure from shifting under water pressure.

[0015] Furthermore, the first housing and the second housing are slidably connected relative to each other, and an extrusion groove structure is formed between the first housing and the second housing. The extrusion groove structure is used to cooperate with the sealing skirt and the flange structure, so that the length of the extrusion groove can be contracted or extended by the relative sliding of the first housing and the second housing, so as to extrude or release the sealing skirt and the flange structure.

[0016] Furthermore, the first housing and the second housing are slidably connected relative to each other, and an extrusion groove structure is formed between the first housing and the second housing. The extrusion groove structure is used to cooperate with the sealing skirt and the flange structure, so that the length of the extrusion groove can be contracted or extended by the relative sliding of the first housing and the second housing, so as to extrude or release the sealing skirt and the flange structure.

[0020] The outer wall of the support portion protrudes towards the slit end, so that the outer wall of the support portion fits against the inner wall of the one-way valve body to support the one-way valve body, so as to avoid the water pressure at the slit end being greater than the water pressure at the opening end, which would cause the slit end to deform and thus affect the closure and sealing effect of the slit end.

[0021] According to the first aspect and the third aspect, the technical solution of this utility model provides a one-way valve assembly and a water purifier structure having the same, comprising:

[0022] A one-way valve body, the one-way valve body being made of a flexible material, the one-way valve body having an open end and a slit end, the sidewall of the one-way valve body converging from the open end to the slit end;

The support portion supports the inner wall of the one-way valve body, and the flanged structure extends radially outward from the support portion. Liquid flowing into the open end can pass through the support structure and flow out from the slit end.

[0024] A first housing and a second housing are used to clamp the flange structure, thereby limiting the axial displacement of the support structure and the one-way valve body.

[0025] The one-way valve has a sealing skirt at its open end. The sealing skirt covers or presses against the flanged structure. The outer diameter of the flanged structure is larger than the inner diameter of the first housing and the outer diameter of the second housing, so that the first housing and the second housing can clamp the flanged structure and the sealing skirt together to prevent the flanged structure from shifting under water pressure.

[0026] According to the first aspect and the fourth aspect, the technical solution of this utility model provides a one-way valve assembly and a water purifier structure having the same, comprising:

[0027] A one-way valve body, the one-way valve body being made of a flexible material, the one-way valve body having an open end and a slit end, the sidewall of the one-way valve body converging from the open end to the slit end;

[0028] A support structure, made of a rigid material, is installed within the one-way valve body. The support structure includes a support portion disposed within the open end, capable of supporting the inner wall of the one-way valve body.

[0029] The outer contour shape of the support portion is adapted to the shape of the inner cavity wall of the one-way valve body; or the inner sidewall of the support portion is concave in an arc shape from the edge to the center, and the outer sidewall of the support portion is convex in an arc shape from the edge to the center, so that the support portion has a hemispherical structure; or the outer sidewall of the support portion extends protruding towards the slit end, so as to support the inner cavity wall of the one-way valve body through the outer sidewall of the support portion, and the inner sidewall of the support portion extends concave towards the slit end to form a receiving cavity, so as to contain liquid through the receiving cavity of the support portion.

[0032] A one-way valve assembly is installed at the water inlet, and the one-way valve assembly is any one-way valve assembly in the above-described scheme.

[0033] As can be seen from the above technical solution, the one-way valve assembly of this utility model, with its flexible valve body and sidewall structure that converges from the open end to the slit end, not only reduces the valve opening pressure by utilizing the material deformation characteristics, but also allows for rapid closure due to elasticity when there is no positive fluid pressure, ensuring the accuracy of one-way flow and the reliability of reverse sealing. The support part of the rigid support structure not only effectively supports the inner wall of the flexible valve body, preventing it from deforming or collapsing during fluid pressure fluctuations or long-term use, thus improving the structural stability and service life of the assembly, but also integrates the filtration function through uniformly arranged filter holes on the surface, eliminating the need for additional filtration devices, simplifying the system structure, reducing manufacturing costs and leakage risks, and adapting to the application needs of multiple fields.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Example 1:

[0053] Please refer to the following: Figures 1 to 4 This embodiment provides a one-way valve assembly, including: a one-way valve body 100 and a support structure 200. The one-way valve body 100 is made of a flexible material and has an open end 110 and a slit end 120. The sidewall of the one-way valve body 100 converges from the open end 110 to the slit end 120. The support structure 200 is made of a rigid material and is installed inside the one-way valve body 100. The support structure 200 includes a support portion 210, and a plurality of filter holes 230 are uniformly arranged on the surface of the support portion 210 to filter the liquid flowing from the open end 110 to the slit end 120. The support portion 210 is disposed inside the open end 110 and can support the inner wall of the one-way valve body 100. The one-way valve body 100 is made of rubber material, and the support structure 200 is made of steel material. The direction from the opening end 110 to the slit end 120 is under positive pressure, and the direction from the slit end 120 to the opening end 110 is under negative pressure. In this embodiment, the slit end 120 is a duckbill-shaped structure. In other possible implementations, such as... Figure 9 As shown, the slit end 120 can be cross-shaped or other irregular structures.

[0054] As can be seen, the one-way valve assembly and the water purifier structure with it in this embodiment, with the flexible valve body and the side wall structure that converges from the open end 110 to the slit end 120, not only reduces the valve opening pressure by utilizing the material deformation characteristics, but also can close quickly by relying on elasticity when there is no positive fluid pressure, ensuring the accuracy of one-way flow and the reliability of reverse sealing; the support part 210 of the rigid support structure 200 can not only effectively support the inner cavity wall of the flexible valve body, preventing it from deforming or collapsing during fluid pressure fluctuations or long-term use, thus improving the structural stability and service life of the assembly, but also integrates the filtration function through the filter holes 230 uniformly arranged on the surface, eliminating the need for additional filtration devices, simplifying the system structure, reducing manufacturing costs and leakage risks, and adapting to the application needs of multiple fields.

[0055] Optionally, the outer contour shape of the support portion 210 is adapted to the inner cavity wall shape of the one-way valve body 100. This arrangement enables the support portion 210 to form a full and close support contact with the inner cavity wall of the one-way valve body 100, so that the one-way valve body 100 can be rigidly supported by the support portion 210 under back pressure, thereby preventing the flexible one-way valve body 100 from undergoing plastic deformation such as inward turning or sagging under high back pressure.

[0056] Optionally, the inner wall of the support portion 210 is concave in an arc shape from the edge to the center, and the outer wall of the support portion 210 is convex in an arc shape from the edge to the center, so that the support portion 210 has a hemispherical structure. With this configuration, the outer wall of the support portion 210 can form a closer contact with the converging inner wall of the one-way valve body 100, increasing the support contact area, making the support force distribution more uniform, avoiding local stress concentration that could damage the one-way valve body 100. At the same time, the excellent mechanical properties of the hemispherical structure enhance the impact resistance of the support portion 210 itself, further enhancing the structural stability of the one-way valve assembly.

[0057] Optionally, the outer sidewall of the support portion 210 protrudes towards the slit end 120 to support the inner wall of the one-way valve body 100. The inner sidewall of the support portion 210 is recessed towards the slit end 120 to form a receiving cavity, so that the receiving cavity of the support portion 210 can hold liquid and facilitate filtration through multiple filter holes 230. With this configuration, the receiving cavity can temporarily store the liquid flowing in from the opening end 110 in advance, so that the liquid forms a buffer in the receiving cavity and then passes evenly through the filter holes 230. This reduces the direct impact of the fluid on the filter holes 230, reduces the probability of filter hole clogging, ensures filtration efficiency and stability, and improves the smoothness of liquid flow, further optimizing the overall working performance of the one-way valve assembly.

[0058] In this embodiment, as Figures 1 to 4 As shown, the support structure 200 also includes a flange structure 220, which extends radially outward along the support portion 210. The opening end 110 of the one-way valve is provided with a sealing skirt 130, which covers or presses against the flange structure 220. The sealing skirt 130 and the flange structure 220 can form a double limit on the support structure 200 in both the axial and radial directions, restricting the support structure 200 from shifting or falling off under fluid impact, and ensuring that the support portion 210 provides stable and reliable support for the valve body and the filtration effect of the filter hole 230.

[0059] Optionally, the inner surface of the sealing skirt 130 is recessed outward in a radial direction to form an assembly groove 131, which is correspondingly provided with the flange structure 220 so that when the support structure 200 is installed in the one-way valve body 100, the flange structure 220 can be at least partially embedded in the assembly groove 131.

[0060] By providing an assembly groove 131 corresponding to the flange structure 220 on the inner surface of the sealing skirt 130, the flange structure 220 is at least partially embedded in the groove during installation, forming a mechanical interlocking positioning, which restricts the radial movement and circumferential rotation between the support structure 200 and the one-way valve body 100, greatly improving the connection stability after assembly and avoiding relative displacement under long-term use or fluid impact.

[0061] Optionally, the first housing 300 and the second housing 400 are used to clamp the flange structure 220, thereby limiting the axial displacement of the support structure 200 and the one-way valve body 100. The outer diameter of the flange structure 220 is larger than the inner diameter of the first housing 300 and the outer diameter of the flange structure 220 is larger than the inner diameter of the second housing 400, so that the first housing 300 and the second housing 400 can clamp the flange structure 220 and the sealing skirt 130 together to prevent the flange structure 220 from shifting under water pressure.

[0062] Preferably, the first housing 300 and the second housing 400 are connected by threads, allowing them to slide relative to each other. A compression groove structure is formed between the first housing 300 and the second housing 400. This compression groove structure engages with the sealing skirt 130 and the flange structure 220, allowing the compression groove to contract or extend by sliding the first housing 300 and the second housing 400 relative to each other, thereby compressing or releasing the sealing skirt 130 and the flange structure 220. A first abutment surface 510 is formed on the first housing 300, and a second abutment surface 520 is formed on the second housing 400. Sliding the first housing 300 and the second housing 400 allows the first abutment surface 510 and the second abutment surface 520 to move closer together or further apart. The first abutment surface 510 and the second abutment surface 520 respectively compress and clamp the two ends of the sealing skirt 130 and the flange structure 220.

[0063] In this embodiment, the filter holes 230 are arranged in a honeycomb or array pattern, and the diameter of the filter holes 230 is smaller than the critical size at which the slit end 120 undergoes extrusion deformation under water pressure.

[0064] The multiple honeycomb or array-shaped filter holes 230 ensure both filtration area and fluid flow efficiency while uniformly intercepting impurities in the fluid, preventing localized filtration blockage from affecting the normal operation of the valve assembly. Furthermore, the design of the filter hole diameter 230 being smaller than the critical size for water pressure extrusion deformation of the one-way valve body 100 allows the rigid edges of the filter holes 230 to form multi-point support for the inner wall of the flexible one-way valve body 100, further extending the service life of the one-way valve body 100 and balancing filtration effect, flow efficiency, and deformation resistance.

[0065] Example 2:

[0066] This embodiment provides a one-way valve assembly, including: a one-way valve body 100 and a support structure 200. The one-way valve body 100 is made of a flexible material and has an open end 110 and a slit end 120. The sidewall of the one-way valve body 100 converges from the open end 110 to the slit end 120. The support structure 200 is made of a rigid material and is installed inside the one-way valve body 100. The support structure 200 includes a support portion 210. The support portion 210 is disposed within the opening end 110 and can support the inner cavity wall of the one-way valve body 100. The outer wall of the support portion 210 protrudes towards the slit end 120, so that the outer wall of the support portion 210 fits against the inner cavity wall of the one-way valve body 100, thereby supporting the one-way valve body 100 to prevent the water pressure at the slit end 120 from being greater than that at the opening end 110, which would cause deformation of the slit end 120 and affect its sealing effect. The one-way valve body 100 is made of rubber material, and the support structure 200 is made of steel material. The direction from the opening end 110 to the slit end 120 is positive pressure, and the direction from the slit end 120 to the opening end 110 is negative pressure. In this embodiment, the slit end 120 is a straight, duckbill-shaped structure. In other possible implementations, such as Figure 9 As shown, the slit end 120 can be cross-shaped or other irregular structures.

[0067] The one-way valve body 100, made of rubber material, has an open end 110 and a duckbill-shaped slit end 120, with the sidewalls converging from the open end 110 to the slit end 120. Combined with a built-in rigid steel support structure 200, the design of the outer wall of the support part 210 protruding towards the slit end 120 and tightly fitting against the inner wall of the one-way valve body 100 provides stable support. This effectively prevents deformation of the one-way valve body 100 when the water pressure at the slit end 120 is greater than that at the open end 110 under back pressure conditions, ensuring the sealing effect of the slit end 120. Furthermore, the slit end 120 can be flexibly configured into a cross shape or other irregular shapes, improving the applicability and operational reliability of the one-way valve assembly.

[0068] Example 3:

[0069] This embodiment provides a one-way valve assembly, such as Figures 1 to 4 As shown, the system includes: a one-way valve body 100, a support structure 200, a first housing 300, and a second housing 400. The one-way valve body 100 is made of a flexible material and has an open end 110 and a slit end 120. The sidewall of the one-way valve body 100 converges from the open end 110 to the slit end 120. The support structure 200 is made of a rigid material and is installed inside the one-way valve body 100. The support structure 200 includes a support portion 210 and a flange structure 220. The support portion 210 can support the inner wall of the one-way valve body 100, and the flange structure 220 extends radially outward along the support portion 210. The flow-in flow-through from the open end 110... Liquid can flow through the support structure 200 and out from the slit end 120. The first housing 300 and the second housing 400 are used to clamp the flange structure 220, thereby limiting the axial displacement of the support structure 200 and the one-way valve body 100. The opening end 110 of the one-way valve is provided with a sealing skirt 130, which covers or presses against the flange structure 220. The outer diameter of the flange structure 220 is larger than the inner diameter of the first housing 300, and the outer diameter of the flange structure 220 is larger than the inner diameter of the second housing 400, so that the first housing 300 and the second housing 400 can clamp the flange structure 220 and the sealing skirt 130 together to prevent the flange structure 220 from shifting under water pressure. The one-way valve body 100 is made of rubber material, and the support structure 200 is made of steel material. The direction from the opening end 110 to the slit end 120 is positive pressure, and the direction from the slit end 120 to the opening end 110 is back pressure. In this embodiment, the slit end 120 is a duckbill-shaped structure. In other possible implementations, such as... Figure 9 As shown, the slit end 120 can be cross-shaped or other irregular structures.

[0070] By using rubber material to fabricate a one-way valve body 100 with an open end 110, a duckbill-shaped slit end 120, and sidewalls converging from the open end 110 to the slit end 120, and in conjunction with a built-in rigid steel support structure 200, the support part 210 supports the inner wall of the one-way valve body 100, effectively preventing deformation of the one-way valve body 100 when the water pressure at the slit end 120 is greater than that at the open end 110 under back pressure conditions, thus ensuring the sealing effect of the slit end 120; at the same time, with the help of the support... The flange structure 220 of structure 200 cooperates with the sealing skirt 130 of the opening end 110 of the one-way valve body 100. The clamping and fixing of the two by the first housing 300 and the second housing 400 can limit the axial displacement of the support structure 200 and the one-way valve body 100, prevent the flange structure 220 from shifting under water pressure, improve the structural stability and assembly reliability of the component, and the slit end 120 can also be flexibly set as a cross-shaped or other irregular structure, further expanding the application scenarios of the one-way valve component.

[0071] Example 4:

[0072] This embodiment provides a one-way valve assembly, such as Figures 1 to 4 As shown, the system includes a one-way valve body 100 and a support structure 200. The one-way valve body 100 is made of a flexible material and has an open end 110 and a slit end 120. The sidewalls of the one-way valve body 100 converge from the open end 110 to the slit end 120. The support structure 200 is made of a rigid material and is installed inside the one-way valve body 100. The support structure 200 includes a support portion 210, which is disposed inside the open end 110 and can support the inner wall of the one-way valve body 100. The outer surface of the support portion 210... The contour shape is adapted to the shape of the inner cavity wall of the one-way valve body 100; or the inner sidewall of the support portion 210 is concave in an arc shape from the edge to the center, and the outer sidewall of the support portion 210 is convex in an arc shape from the edge to the center, so that the support portion 210 has a hemispherical structure; or the outer sidewall of the support portion 210 extends protruding towards the slit end 120 to support the inner cavity wall of the one-way valve body 100 through the outer sidewall of the support portion 210, and the inner sidewall of the support portion 210 extends concave towards the slit end 120 to form a receiving cavity to contain liquid through the receiving cavity of the support portion 210. The one-way valve body 100 is made of rubber material, and the support structure 200 is made of steel material. The direction from the opening end 110 to the slit end 120 is positive pressure, and the direction from the slit end 120 to the opening end 110 is back pressure. In this embodiment, the slit end 120 is a duckbill-shaped structure. In other possible implementations, such as Figure 9 As shown, the slit end 120 can be cross-shaped or other irregular structures.

[0073] The one-way valve body 100, made of rubber material, has an open end 110, a duckbill-shaped slit end 120, and sidewalls that converge from the open end 110 to the slit end 120. It is combined with a built-in rigid steel support structure 200. The support part 210 can be designed in three ways: its outer contour can be adapted to the inner wall of the one-way valve body 100, it can be a hemispherical structure, or its outer sidewall can protrude towards the slit end 120 and its inner sidewall can form a receiving cavity. This design can provide stable support for the one-way valve body 100, effectively prevent the slit end 120 from deforming due to the water pressure being greater than that of the open end 110 under back pressure conditions, and ensure the closing and sealing effect of the slit end 120. It can also achieve smooth flow of liquid through the receiving cavity. At the same time, the slit end 120 can be flexibly set as a cross-shaped or other irregular structure.

[0074] Example 5:

[0075] This embodiment provides a water purifier, such as... Figures 1 to 8 As shown, it includes: a water purifier body and a one-way valve assembly. The water purifier body includes an inlet and an outlet. The one-way valve assembly is installed at the inlet. The one-way valve assembly is any one-way valve assembly in the above embodiments.

[0076] The beneficial effects of this water purifier design are that the one-way flow characteristic of the one-way valve assembly effectively prevents backflow of water inside the purifier body, avoiding the mixing of purified water and unfiltered water that would affect the quality of the output water. Furthermore, the synergistic design of the rigid support structure 200 of the one-way valve assembly and the flexible valve body ensures the stability and smoothness of the water inlet process. At the same time, the filtration function integrated into the one-way valve assembly can also perform pre-filtration of the incoming water, intercepting impurities in the water to protect the internal filter element of the water purifier, reducing the probability of filter element clogging, extending the service life of the filter element, and reducing the later maintenance costs of the water purifier. Overall, this improves the reliability and economic efficiency of the water purifier.

[0077] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0078] The flexible valve body, combined with the sidewall structure that converges from the open end 110 to the slit end 120, reduces the valve opening pressure by utilizing the material deformation characteristics and can close quickly and elastically when there is no positive fluid pressure, ensuring the accuracy of unidirectional flow and the reliability of reverse sealing. The support part 210 of the rigid support structure 200 not only effectively supports the inner wall of the flexible valve body, preventing it from deforming or collapsing during fluid pressure fluctuations or long-term use, thus improving the structural stability and service life of the component, but also integrates the filtration function through the uniformly arranged filter holes 230 on the surface, eliminating the need for additional filtration devices, simplifying the system structure, reducing manufacturing costs and leakage risks, and adapting to the application needs of multiple fields.
