Technical Field
[0001] This utility model relates to the technical field of tap water treatment, and in particular to a scale inhibitor device for tap water. Background Technology
[0002] Scale in tap water is mainly formed by the precipitation of minerals such as calcium and magnesium, and is especially common in water heaters and pipes. To effectively inhibit scale formation, various scale inhibitors and filters have appeared on the market. Among them, filters are commonly used, and most filters rely on physical or chemical processes to remove impurities from the water.
[0003] In existing technologies, filters inevitably become clogged during water purification. Therefore, in order to ensure the normal use of tap water, it is necessary to replace the filter cartridge regularly to maintain the scale inhibition device. Even if the water valve is turned off in advance when replacing the filter cartridge, there will still be a small amount of residual liquid in the water pipe, which will inevitably cause water leakage when maintaining the scale inhibition device, thus increasing the difficulty of cleaning the scale inhibition device after maintenance. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tap water scale inhibitor device in order to solve the technical problems mentioned in the background art.

[0007] A filter cartridge kit, which is installed inside the filter cartridge chamber, is used to filter tap water;
[0008] There are two connecting female seats, which are respectively located at both ends of the housing. Each connecting female seat includes a sleeve, a limiting ring, and a piston. The sleeve is inserted into the end of the housing. The end of the sleeve away from the housing is machined with an internal thread for connecting to a water pipe. Two limiting rings are spaced apart inside the sleeve. The piston is connected between the two limiting rings by an elastic element.
[0009] There are two male connectors, which are inserted into both ends of the filter element kit. The male connector is mainly composed of a connecting cover and an insertion tube. The connecting cover is inserted into the filter element kit, and the end of the connecting cover away from the filter element kit is fixedly connected to the insertion tube for inserting the piston, so that the filter element kit is connected to the female connector.
[0010] Furthermore, the connecting cover has a round hole on the side near the filter element, the bottom end of the round hole extends into the insertion tube, and the outer wall of the insertion tube has a water inlet groove communicating with the round hole.
[0011] Furthermore, a connecting groove is provided on the side of the piston near the insertion tube, and a water inlet groove 2 communicating with the connecting groove is provided on the outer wall of the piston.
[0012] Furthermore, the inner wall of the connecting groove protrudes to form a limiting block, and the outer wall of the insertion tube is provided with a foolproof groove for accommodating the limiting block.
[0013] Furthermore, the outer diameter of the piston is equal to the inner diameter of the limiting ring, and a sealing ring that contacts the piston is connected to the inner wall of one of the limiting rings near the filter element assembly.
[0014] Furthermore, the elastic element includes a spring, a slide rail, and a slider. A slide rail is fixedly connected between the two limiting rings, and a slider is slidably connected to the outer wall of the slide rail.

[0018] B+C > A > B.
[0019] In summary, this utility model has at least one of the following beneficial technical effects:
[0020] 1. This tap water scale inhibitor device, through the provided male and female connectors, allows for quick installation of filter cartridges via plug-in connection, significantly reducing the difficulty of subsequent maintenance and improving the practicality of the tap water scale inhibitor device. Furthermore, the female connector is equipped with a limit ring, elastic element, and piston, which allows the piston to block the limit ring when the male connector is removed from the female connector, effectively preventing leakage of residual liquid from the water pipe during filter cartridge replacement and making cleaning after filter cartridge replacement simpler and more convenient.
[0021] 2.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] Example:
[0030] Reference Figure 1 - Figure 4 The present invention discloses a tap water scale inhibitor device, which includes a housing 1, a filter element cavity 5 inside the housing 1, a groove 6 communicating with the filter element cavity 5 on the outer wall of the housing 1, and a cover plate 7 hinged in the groove 6.
[0031] Filter cartridge kit 2, which is installed inside filter cartridge chamber 5, is used to filter tap water;
[0032] There are two connecting female seats 3, which are respectively located at both ends of the housing 1. Each connecting female seat 3 includes a sleeve 31, a limiting ring 32, and a piston 33. The sleeve 31 is inserted into the end of the housing 1. The end of the sleeve 31 away from the housing 1 is machined with an internal thread for connecting to a water pipe. Two limiting rings 32 are spaced apart inside the sleeve 31. The piston 33 is connected between the two limiting rings 32 by an elastic element 8.
[0033] There are two male connectors 4, which are inserted into the two ends of the filter element kit 2 respectively. The male connector 4 is mainly composed of a connecting cover 41 and an insertion tube 42. The connecting cover 41 is inserted into the filter element kit 2. The end of the connecting cover 41 away from the filter element kit 2 is fixedly connected to the insertion tube 42 for inserting the piston 33, so that the filter element kit 2 is connected to the female connector 3.
[0034] In this embodiment, observation Figure 1 It can be seen that by providing a filter element cavity 5 inside the housing 1, and a slot 6 communicating with the filter element cavity 5 on the outer wall of the housing 1, and a cover plate 7 hinged inside the slot 6, the filter element kit 2 can be placed inside the filter element cavity 5 through the slot 6, and then the cover plate 7 is closed to protect the filter element kit 2. This allows the tap water entering the housing 1 to pass through the filter element kit 2, and the scale and impurities in the tap water to be filtered out by the filter element kit 2, thus achieving the scale inhibition effect.
[0035] And combined Figure 1 and Figure 2 It can be seen that connecting females 3 are connected to both ends of the housing 1, which allows the two ends of the housing 1 to be connected to the water pipe, facilitating the installation of the tap water scale inhibitor. Connecting males 4 are connected to both ends of the filter cartridge kit 2, so that when the filter cartridge kit 2 is installed into the filter cartridge cavity 5, the filter cartridge kit 2 is connected to the water pipe by inserting the connecting males 4 and the connecting females 3, making the installation of the filter cartridge kit 2 simpler and more convenient.
[0036] Even if the water valve is turned off before replacing the filter element, there will still be a small amount of residual liquid in the water pipe, which will inevitably cause water leakage when maintaining the scale inhibition device, making the subsequent cleaning of the scale inhibition device more difficult.
[0037] Therefore, observe Figure 2 It can be observed that the connecting female seat 3 includes a sleeve 31, a limiting ring 32, and a piston 33. The sleeve 31 is inserted into the end of the housing 1. The end of the sleeve 31 away from the housing 1 is machined with an internal thread for connecting to a water pipe. Two limiting rings 32 are spaced apart inside the sleeve 31, and the piston 33 is connected between the two limiting rings 32 by a spring member 8. Further observation is then conducted. Figure 3 It can be observed that the connecting male socket 4 mainly consists of a connecting cover 41 and an insertion tube 42. The connecting cover 41 is inserted into the filter element kit 2, and the end of the connecting cover 41 away from the filter element kit 2 is fixedly connected to the insertion tube 42 for inserting the piston 33, so that the filter element kit 2 can be inserted as follows: Figure 2 The status indicates that it is connected to connector 3.
[0038] When the male connector 4 is pulled out of the female connector 3, the piston 33 will be pushed into the limiting ring 32 under the push of the spring element 8, thereby blocking the female connector 3 and achieving the effect of cutting off water supply, avoiding leakage of residual liquid in the water pipe, and thus effectively reducing the difficulty of cleaning the filter element kit 2 after replacement.
[0039] Since the filter element kit 2 is connected to the connecting female seat 3 via the connecting male seat 4, in order to ensure the connection stability of the filter element kit 2, we assume that the end distance of the connecting male seats 4 at both ends of the filter element kit 2 is A; the distance between the two connecting female seats 3 is B; and the distance between the two limiting rings 32 within the same connecting female seat 3 is C.
[0040] At this point, to ensure the connection stability of filter cartridge 2, the length of A needs to be greater than the length of B. This allows the male connectors 4 at both ends of filter cartridge 2 to be stably inserted into the female connectors 3. Since filter cartridge 2 is a consumable part that needs to be replaced, to ensure that filter cartridge 2 can be easily disassembled and replaced, the length of A needs to be less than the length of B+C. Therefore, when filter cartridge 2 needs to be replaced, only a lateral force needs to be applied to filter cartridge 2, causing the insertion tube 42 of the male connector 4 on that side to be fully inserted into the corresponding female connector 3, and the male connector 4 on the other end to be completely disengaged from the female connector 3. Then, the male connector 4 is pulled off filter cartridge 2, and the force applied to filter cartridge 2 is released. Because filter cartridge 2 has lost one male connector 4, its length is now less than B, making filter cartridge 2 easy to remove for replacement. This makes replacing filter cartridge 2 very simple, effectively improving the practicality of the tap water scale inhibitor device.
[0041] Among them, the filter kit 2 mentioned above is a commercially available product, such as Haier scale-inhibiting pre-filter T5, Everpure4FC-LS, etc., which will not be elaborated on here.
[0042] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the connecting cover 41 has a round hole 9 on the side near the filter element, the bottom end of the round hole 9 extends into the insertion tube 42, and the outer wall of the insertion tube 42 has a water inlet groove 10 communicating with the round hole 9.
[0043] The piston 33 has a connecting groove 11 on the side near the insertion tube 42, and the outer wall of the piston 33 has a water inlet groove 12 that communicates with the connecting groove 11.
[0044] The inner wall of the connecting groove 11 protrudes to form a limiting block 13, and the outer wall of the insertion tube 42 is provided with a foolproof groove 14 for accommodating the limiting block 13.
[0045] In this embodiment, observation Figure 4It can be observed that by providing a circular hole 9 on the side of the connecting cover 41 near the filter element, with the bottom end of the circular hole 9 extending into the insertion tube 42, and providing a water inlet groove 10 communicating with the circular hole 9 on the outer wall of the insertion tube 42, and providing a connecting groove 11 on the side of the piston 33 near the insertion tube 42, and providing a water inlet groove 2 12 communicating with the connecting groove 11 on the outer wall of the piston 33, when the insertion tube 42 is inserted into the connecting groove 11, the water inlet groove 10 and the water inlet groove 2 12 overlap, so that the water in the water pipe can enter the circular hole 9 through the water inlet groove 2 12 and the water inlet groove 10, and then enter the filter element kit 2 through the circular hole 9, thereby achieving descaling and filtration of tap water.
[0046] Further observation Figure 4 It can be seen that the inner wall of the connecting groove 11 has a protrusion to form a limiting block 13, and the outer wall of the insertion tube 42 has a foolproof groove 14 for accommodating the limiting block 13. This ensures that when the insertion tube 42 is inserted into the connecting groove 11, the water inlet 10 and the water inlet 2 12 are in an overlapping state, thereby ensuring water inlet efficiency.
[0047] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the outer diameter of the piston 33 is equal to the inner diameter of the limiting ring 32, and a sealing ring 15 that contacts the piston 33 is connected to the inner wall of the limiting ring 32 near the filter element kit 2.
[0048] In this embodiment, observation Figure 2 It can be seen that by making the outer diameter of the piston 33 equal to the inner diameter of the limiting ring 32, and connecting the inner wall of one of the limiting rings 32 near the filter element kit 2 to a sealing ring 15 that contacts the piston 33, the piston 33 can be inserted into the limiting ring 32 when pushed by the spring member 8, so that the piston 33 contacts the sealing ring 15 to seal, which can effectively prevent water leakage when replacing the filter element kit 2.
[0049] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the elastic component 8 includes a spring 81, a slide rail 82 and a slider 83. The slide rail 82 is fixedly connected between the two limiting rings 32. The slider 83 is slidably connected to the outer wall of the slide rail 82. The slider 83 is fixedly connected to the side of the piston 33 away from the connecting groove 11. The spring 81 is fixedly connected to the side of the slider 83 away from the piston 33.
[0050] In this embodiment, the elastic element 8 is mainly composed of a spring 81, a slide rail 82, and a slider 83. The slide rail 82 is fixedly connected between the two limiting rings 32, and the slider 83 is slidably connected to the outer wall of the slide rail 82. The slider 83 is fixedly connected to the side of the piston 33 away from the connecting groove 11, and the side of the slider 83 away from the piston 33 is fixedly connected to the spring 81. When the connecting male seat 4 is disengaged from the connecting female seat 3, the spring 81 pushes the slider 83 to slide, causing the piston 33 to insert into the limiting ring 32, so as to effectively ensure that there is no water leakage.
[0051] The implementation principle of the above embodiment is as follows: Open the cover plate 7, and then place one of the connecting male seats 4 as... Figure 3 As shown in the diagram, the filter element kit 2 is installed at one end. Then, the male connector 4 is inserted into the female connector 3, and another male connector 4 is inserted into another female connector 3. Finally, the male connector 4 is inserted into the other end of the filter element kit 2 to complete the installation of the filter element kit 2.
[0052] When the filter cartridge 2 needs to be replaced, simply apply a lateral force to the filter cartridge 2 so that the insertion tube 42 of the male connector 4 on that side is fully inserted into the corresponding female connector 3, and the male connector 4 on the other end is completely detached from the female connector 3. Then, pull the male connector 4 off the filter cartridge 2 and release the force applied to the filter cartridge 2. At this point, since the male connector 4 has been removed, the filter cartridge 2 can be easily removed for replacement, making the replacement of the filter cartridge 2 very simple and effectively improving the practicality of the tap water scale inhibitor.
[0053] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
