Description

Technical Field

[0001] This utility model relates to the field of scale inhibitor technology, and in particular to a scale inhibitor structure. Background Technology

[0002] Scale is closely related to people's production and daily life. Under high temperature conditions, salts such as calcium and magnesium, which are slightly soluble in water, will precipitate and condense on the surface of metal, which can easily waste electricity, reduce the heating efficiency of electrical appliances, and cause metal materials to burn due to local overheating, resulting in accidents and hindering the long-term use of household appliances.

[0003] In homes and some commercial establishments, pre-scale inhibitors are often installed to remove limescale. Chinese patent CN103787513B discloses a water purification and scale prevention device installed on a pipeline. Key features include: a scale-preventing tube, a filter screen, a scale inhibitor, and end caps. The scale-preventing tube is a cylindrical body open at both ends. The filter screen is installed at both ends. The scale inhibitor is placed in the cavity formed by the filter screen and the scale-preventing tube. End caps are connected to both ends of the scale-preventing tube. The scale inhibitor is made of a copper-based catalyst alloy with scale-preventing properties, which effectively prevents limescale formation.

[0004] However, in actual use, the installation and positioning structure of the filter screen is relatively complicated, and because the filter screen is located inside the device, it is difficult for users to disassemble or install the filter screen. At the same time, the water flow rate of the filter screen is small, and the amount of purified water cannot meet the user's needs. Utility Model Content

[0005] The purpose of this utility model is to provide a scale inhibitor structure, which aims to solve the problem that the filter screen installation structure of the existing scale inhibitor structure is complicated and inconvenient for users to disassemble and install.

[0006] To achieve the above objectives, the present invention provides a scale inhibitor structure, the key features of which include:

[0007] A cylindrical body having an inlet and an outlet, the inner cavity of the cylindrical body being used to place a scale inhibitor, a first filter screen structure being provided at the inlet, and a second filter screen structure being provided at the outlet;

[0008] The first filter structure and / or the second filter structure are cylindrical filter structures, with one end of the cylindrical filter structure being open. The open end of the cylindrical filter structure is provided with multiple elastic grooves spaced apart circumferentially, so as to divide the open end of the cylindrical filter structure into multiple elastic petals circumferentially through the multiple elastic grooves. The elastic force of the multiple elastic petals opening outward makes the elastic petals fit tightly against the inner wall of the water inlet or the water outlet, thereby enabling the detachable installation of the cylindrical filter structure.

[0009] Furthermore, the inlet and / or the outlet protrudes outward to form an annular protrusion, so that the opening of the inlet or the outlet is formed at the end of the annular protrusion; and / or

[0010] The opening of the cylindrical filter structure protrudes outward in the circumferential direction to form an annular folded edge, which abuts against the opening of the water inlet or the water outlet for positioning.

[0011] Furthermore, it also includes a fixing joint, which is threadedly connected to the annular protrusion. The fixing joint is arranged vertically to further limit and install the cylindrical filter structure at the inlet or the outlet.

[0012] Furthermore, the inner circumferential surface of the fixed joint extends inward to form a step for abutting, so that by twisting the fixed joint, the step for abutting is moved toward the opening of the inlet or the outlet, so that the annular folded edge is positioned between the step for abutting and the opening of the inlet or the outlet.

[0013] Furthermore, an elastic seal is provided between the fixed joint and the annular protrusion.

[0014] Furthermore, the outer periphery of the top of the annular protrusion extends downward to form an annular groove, and the elastic seal is installed in the annular groove so that one end of the elastic seal abuts against the abutting step, and the outer side of the elastic seal abuts against the inner peripheral surface of the fixed joint.

[0015] Furthermore, multiple flexible channels are respectively opened vertically on the cylindrical filter structure.

[0016] Furthermore, the cylindrical filter structure has multiple filter holes, and the diameter of each filter hole is smaller than the minimum particle size of the scale inhibitor.

[0017] And / or, the plurality of filter holes are distributed circumferentially at intervals, and the plurality of filter holes are also spaced apart along the length direction of the cylindrical filter structure.

[0018] Furthermore, the number of elastic lobes is two, three, four or more, the multiple elastic lobes have approximately the same shape and are distributed circumferentially, and an elastic through groove is formed between two adjacent elastic lobes.

[0019] Furthermore, the water inlet and the water outlet are respectively located at opposite ends of the cylindrical body along the axial direction.

[0020] As can be seen from the above technical solution, the scale inhibitor structure of this utility model, by setting an inlet and an outlet on a cylindrical body, and placing the scale inhibitor in the inner cavity of the cylindrical body, filters the raw water flowing in from the inlet through the scale inhibitor, and discharges the filtered water from the outlet. The first filter screen structure can prevent the scale inhibitor from leaking from the inlet, and the second filter screen structure can prevent the scale inhibitor from leaking from the outlet; wherein, the first filter screen structure and / or the second filter screen structure is a cylindrical filter screen structure, one end of the cylindrical filter screen structure is open, and the open end of the cylindrical filter screen structure is provided with multiple elastic grooves spaced apart along the circumference to hold the cylindrical filter screen structure The opening end of the structure is divided into multiple elastic petals along the circumference. Each elastic petal can contract radially inward, and the elastic force of the multiple elastic petals opening outward makes the elastic petals fit tightly against the inner wall of the inlet or outlet, thus allowing for detachable installation of the cylindrical filter structure. With this design, the entire cylindrical filter structure can be installed at the inlet or outlet through the elastic action of the elastic petals themselves. This cylindrical filter structure does not require a complicated installation structure, and users can easily install the cylindrical filter structure in the correct position. Installation and disassembly are simple and quick, saving time and effort. Moreover, the structure is simple and compact, and the manufacturing cost is low.

[0032] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] It is worth noting that, in this application, the appendix is ​​attached. Figure 1 Based on this, the scale inhibitor structure is placed vertically.

[0034] Please refer to the following: Figures 1 to 6 This embodiment provides a scale inhibitor structure, the key features of which include a cylindrical body 100, having an inlet 110 and an outlet 120. The inner cavity of the cylindrical body 100 is used to place filter media or scale inhibitor. A first filter screen structure is provided at the inlet 110, and a second filter screen structure is provided at the outlet 120. The first filter screen structure and / or the second filter screen structure is a cylindrical filter screen structure 500, with one end of the cylindrical filter screen structure 500 being open 510. The cylindrical filter structure 500 is configured with multiple elastic grooves 530 spaced circumferentially at the opening 510 end, so that the opening 510 end of the cylindrical filter structure 500 is divided into multiple elastic petals 540 circumferentially by the multiple elastic grooves 530. The elastic force of the multiple elastic petals 540 opening outward makes the elastic petals 540 fit tightly against the inner wall of the inlet 110 or outlet 120, thereby enabling the detachable installation of the cylindrical filter structure 500.

[0035] As can be seen, the scale inhibitor structure of this utility model, by setting an inlet 110 and an outlet 120 on a cylindrical body 100, and placing the scale inhibitor in the inner cavity of the cylindrical body 100, filters the raw water flowing in from the inlet 110 through the scale inhibitor, and discharges the filtered water from the outlet 120. The first filter screen structure can prevent the scale inhibitor from leaking from the inlet 110, and the second filter screen structure can prevent the scale inhibitor from leaking from the outlet 120. The first filter screen structure and / or the second filter screen structure is a cylindrical filter screen structure 500, with one end of the cylindrical filter screen structure 500 having an opening 510. Multiple elastic grooves 530 are spaced circumferentially at the opening 510 end of the cylindrical filter screen structure 500 to divide the opening 510 end of the cylindrical filter screen structure 500 circumferentially. Multiple elastic flaps 540, each capable of radially contracting inwards, and through the outward elastic force of the flaps 540, tightly adhere to the inner wall of the inlet 110 or outlet 120, thus enabling detachable installation of the cylindrical filter structure 500. This design allows the entire cylindrical filter structure 500 to be installed at the inlet 110 or outlet 120 via the elasticity of the flaps 540 themselves. This configuration eliminates the need for complex positioning and limiting structures, allowing users to easily install the cylindrical filter structure 500 in the correct position. Installation and disassembly are time-saving and labor-saving. Furthermore, the cylindrical filter structure 500 is a three-dimensional structure with a large filtration area and high water flow rate, resulting in a superior user experience.

[0036] In this embodiment, the scale inhibitor can be KDF material, activated carbon particles, quartz sand particles, or strong acid cation exchange resin particles, etc.

[0037] In this embodiment, the inlet 110 and / or outlet 120 extend outward to form an annular protrusion 140, so that the opening of the inlet 110 or outlet 120 is formed at the end of the annular protrusion 140. During installation, the cylindrical filter structure 500 can be installed by inserting the closed end of the cylindrical filter structure 500 into the inlet 110 or outlet 120 and making the annular folded edge 520 abut against the opening of the inlet 110 or the opening of the outlet 120. With the help of the elastic flap 540, the snap-fit ​​fixation can be completed quickly without additional complicated tools, thus improving assembly efficiency.

[0038] In this embodiment, a fixed connector 600 is threadedly connected to the annular protrusion 140. The fixed connector 600 is vertically continuous, allowing the cylindrical filter structure 500 to be further positioned and installed at the inlet 110 or outlet 120. The fixed connector 600 is threaded to the annular protrusion 140. When the fixed connector 600 is screwed, its internal abutment step 610 moves towards the opening near the inlet 110 or outlet 120, clamping the annular folded edge 520 of the cylindrical filter structure 500 between the abutment step 610 and the annular protrusion 140, thus forming an axial limit and improving the overall structural stability. The threaded connection method is simple to operate, requiring no special tools for installation or disassembly, facilitating on-site construction and subsequent maintenance, and significantly reducing labor costs.

[0039] In this embodiment, an elastic seal 700 is provided between the fixed joint 600 and the annular protrusion 140. When the fixed joint 600 is screwed in, the step 610 presses the end face of the elastic seal 700, and the inner circumferential surface of the fixed joint 600 radially presses the outer surface of the elastic seal 700, forming a bidirectional stress constraint. The axial force fills the gap between the annular protrusion 140 and the step 610, and the radial force fills the annular gap between the annular protrusion 140 and the inner circumferential surface. The bidirectional compressive stress achieves high sealing strength under high pressure and can adapt to various complex situations.

[0040] In this embodiment, multiple elastic channels 530 are respectively vertically opened on the cylindrical filter structure 500. The vertical elastic channels 530 cause the elastic flaps 540 to bend and contract inward when subjected to radial compression, reducing the outer diameter of the cylindrical filter structure 500, thereby allowing it to pass smoothly through the inlet 110 or outlet 120. After passing through, the elastic flaps 540 return to their original position due to their own elasticity, locking onto the inner wall of the inlet 110 or outlet 120, thus achieving elastic locking.

[0041] Preferably, the cylindrical filter structure 500 is configured such that the outer diameter of the open end 510 gradually decreases from the outer diameter of the closed end.

[0042] In this embodiment, the cylindrical filter structure 500 has a plurality of filter holes 550, the diameter of each filter hole 550 is smaller than the minimum particle size of the filter material, and the plurality of filter holes 550 are distributed at intervals along the circumference and are also spaced at intervals along the length of the cylindrical filter structure 500.

[0043] It is worth noting that in other embodiments, the filter holes 550 may be of other shapes, which are configured to prevent scale inhibitors from passing through, and the number of filter holes 550 should not be a limitation of this invention.

[0044] Preferably, the number of elastic lobes 540 is two, three, four or more, the multiple elastic lobes 540 are roughly the same in shape and are distributed circumferentially, and an elastic through groove 530 is formed between two adjacent elastic lobes 540. The cylindrical filter structure 500 is made of elastic metal, preferably stainless steel.

[0045] In this embodiment, the inlet and outlet 120 are respectively located at opposite ends of the cylindrical body 100 along the axial direction, so that the water flow passes through the scale inhibitor chamber 130 in a straight line along the axial direction, so that the water flow maximizes the contact with the scale inhibitor and improves the scale inhibition efficiency.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] By providing an inlet 110 and an outlet 120 on a cylindrical body 100, and placing a scale inhibitor inside the inner cavity of the cylindrical body 100, the raw water flowing in from the inlet 110 is filtered through the scale inhibitor, and the filtered water is discharged from the outlet 120. A first filter screen structure prevents the scale inhibitor from leaking from the inlet 110, and a second filter screen structure prevents the scale inhibitor from leaking from the outlet 120. The first and / or second filter screen structures are cylindrical filter screen structures 500, with one end of the cylindrical filter screen structure 500 having an opening 510. Multiple elastic grooves 530 are spaced circumferentially at the opening 510 end of the cylindrical filter screen structure 500, dividing the opening 510 end of the cylindrical filter screen structure 500 into multiple elastic lobes 530. 40. Multiple elastic flaps 540 can all contract radially inward, so that the elastic force of the multiple elastic flaps 540 opening outward can make the elastic flaps 540 fit tightly against the inner wall of the inlet 110 or outlet 120, thereby enabling the detachable installation of the cylindrical filter structure 500. With this configuration, the elasticity of the elastic flaps 540 themselves can be used to install the entire cylindrical filter structure 500 at the inlet 110 or outlet 120. The cylindrical filter structure 500 with this configuration does not require complex positioning and limiting structures. Users can easily install the cylindrical filter structure 500 in the correct position. Installation and disassembly are time-saving and labor-saving. Moreover, the cylindrical filter structure 500 has a large filtration area and a high water flow rate, resulting in a better user experience.
