[0002] Maintaining swimming pool water quality is crucial for ensuring a safe and comfortable swimming environment. The synergistic effect of the filtration system and disinfectants is paramount. Traditional pool filters typically combine physical filtration with chemical disinfection, usually incorporating a disinfectant dispensing device (such as a tablet dispenser or slow-release cartridge) inside the filter. The disinfectant tablets react with the water to form a disinfectant solution, which then mixes into the filtered water to achieve water treatment. However, current technologies generally suffer from the inability to adjust the amount of disinfectant released, severely hindering the precision of water quality management.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a dosing box and a pool filter element, which aims to solve the technical problem that the release of disinfectant solution cannot be controlled in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dosing box includes a box body, a core column that moves axially along the box body, and a cover detachably connected to the core column. The box body has a cavity that matches the peripheral wall of the core column. The core column is used to store disinfectant tablets. The peripheral wall of the box body has a first through hole. The peripheral wall of the core column has a plurality of sets of flow holes arranged axially.

Detailed Implementation

[0030] This utility model provides a dosing box and a swimming pool filter element. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," and "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0032] Please see Figures 1 to 5 As shown, this utility model provides a dosing box, including a box body 1, a core column 2 that moves along the axial direction of the box body 1, and a cover 3 that is detachably connected to the core column 2. The box body 1 has a cavity 11 that matches the peripheral wall of the core column 2. The core column 2 is used to store disinfectant tablets. The peripheral wall of the box body 1 has a first through hole 12. The peripheral wall of the core column 2 has a plurality of sets of flow holes 4 arranged along its axial direction. The water flow area of ​​the plurality of sets of flow holes 4 gradually increases along the axial direction of the core column 2. A positioning component 5 is provided between the box body 1 and the core column 2. The positioning component 5 is used to limit the position of any set of flow holes 4 to correspond with the first through hole 12.

[0033] When in use, the water filtered by the pool filter cartridge flows into the box 1. The water passes through the first through hole 12 and any set of flow holes 4 in sequence into the core column 2, and comes into contact with the disinfectant tablets stored in the core column 2. The water dissolves the disinfectant tablets to form a disinfectant solution, which is then discharged out of the box 1 to kill bacteria in the water, thereby achieving the purpose of purifying the water quality.

[0034] During adjustment, the core column 2 is moved along the axial direction of the housing 1 so that the first through hole 12 corresponds to any set of flow holes 4, and the position of the core column 2 is locked by the positioning component 5. Under the synergistic effect of the first through hole 12 and the set of flow holes 4, the water flow area of ​​the core column 2 is changed, thereby realizing the function of adjusting the release amount of disinfectant solution.

[0035] In this embodiment, the core column 2 moves upward along the axial direction of the box body 1. The larger the water flow area of ​​the core column 2, that is, the larger the water flow area of ​​the core column 2, the more disinfectant is released.

[0036] In addition, it can be set that when the core column 2 moves upward along the axial direction of the box body 1, the smaller the water flow area of ​​the core column 2, the less disinfectant is released.

[0037] In the above, the detachable connection between the core 2 and the cover 3 is a threaded connection, which allows for the insertion of disinfectant tablets into the core 2 by screwing the cover 3 in or out.

[0038] There are two implementation methods for controlling the water flow area using several sets of flow holes 4:

[0039] The first implementation method, see [link / reference] Figure 4 Each group of flow holes 4 includes several second through holes 41 with the same area, and the number of second through holes 41 in each group of flow holes 4 gradually increases along the axial direction of the core column 2. When more second through holes 41 correspond to the first through holes 12, the water flow area of ​​the core column 2 is larger, resulting in a larger release of disinfectant solution. It should be noted that the second through holes 41 in the same group are all located within the projection range of the first through holes 12.

[0040] In this embodiment, one first through hole 12 corresponds to three sets of flow holes 4, and the number of second through holes 41 in each set of flow holes 4 is one, two, and three respectively. Through the above setting, the amount of disinfectant solution released can be intuitively known.

[0041] For the second implementation method, please refer to... Figure 5 Each group of flow holes 4 includes a second through hole 41, and the area of ​​the second through hole 41 in each group of flow holes 4 gradually increases along the axial direction of the core column 2. When a larger area of ​​the second through hole 41 corresponds to the first through hole 12, the water flow area of ​​the core column 2 is larger, and the amount of disinfectant released is greater. It should be noted that the second through hole 41 should be located within the projection range of the first through hole 12.

[0042] Since the area of ​​the first through hole 12 is limited, by setting multiple first through holes 12 and multiple corresponding sets of flow holes 4, the total release of disinfectant solution in a single application can be increased.

[0043] In one embodiment, there are multiple first through holes 12, all of which are arranged in a circular array around the axis of the housing 1; several sets of flow holes 4 are used in conjunction with one first through hole 12. The circular array of multiple first through holes 12 can improve the uniformity of disinfectant release.

[0044] In another embodiment, there are several first through holes 12, and all the first through holes 12 are arranged along the axial direction of the box body 1; several sets of flow holes 4 are used in conjunction with one first through hole 12 to increase the total release of disinfectant solution in a single application.

[0045] In another implementation, see Figure 4The first through hole 12 is a plurality of them, and the plurality of first through holes 12 are arranged in an array along two directions. One direction is arranged along the axial direction of the box body 1, and the other direction is arranged in a circular array along the center line of the box body 1, which further increases the total release of disinfectant liquid in a single application and makes the disinfectant liquid evenly released around the core column 2.

[0046] In a preferred embodiment, see [reference] Figure 1 , 2 The positioning components 5 are in two sets, and the two sets of positioning components 5 are symmetrically arranged to improve the stability of the core column 2 installation.

[0047] Specifically, see Figure 3 The positioning component 5 includes a positioning plate 51 and a locking block 52. The peripheral wall of the housing 1 has mounting holes 14. One side of the positioning plate 51 is fixedly connected to one side of the mounting hole 14. The side of the positioning plate 51 near the core post 2 has several positioning grooves 53 arranged axially along the housing 1. The locking block 52 can be engaged in any of the positioning grooves 53. One side of the positioning plate 51 is fixedly connected to one side of the mounting hole 14, meaning the remaining sides of the positioning plate 51 have gaps with the sidewall of the mounting hole 14, allowing the positioning plate 51 to deform and the locking block 52 to engage in any positioning groove 53. When the locking block 52 engages in any positioning groove 53, it locks the position of the core post 2 on the housing 1, ensuring that throughout the entire operation, the first through hole 12 corresponds to the second through hole 41 within any set of flow holes 4.

[0048] Further, see Figure 3 The positioning plate 51 has a groove 54 on the side near the core column 2, and several positioning slots 53 are located at the bottom of the groove 54. A guide surface 55 is provided between the bottom of the groove 54 and the side wall of the positioning slot 53. The locking block 52 moves within the groove 54, and the groove 54 limits the range of movement of the locking block 52, preventing the locking block 52 from dislodging from the groove 54, thereby preventing the core column 2 from dislodging from the cavity 11. In addition, the guide surface 55 facilitates the sliding of the locking block 52 into or out of the groove 54, thereby making it easier to adjust the release amount of disinfectant solution.

[0049] In a preferred embodiment, see [reference] Figure 1 The outer wall of the box body 1 is provided with an arc surface 13, which is recessed towards the inside of the box body 1. When the tablet is inserted or the amount of disinfectant solution is adjusted, the user's hand grips the box body 1, and the arc surface 13 fits the hand, thereby improving the comfort of gripping the box body 1.

[0050] See Figure 6-11This utility model also provides a swimming pool filter element, including a filter element 6, an end cap 7, and a dosing box. The top of the filter element 6 is screwed to the end cap 7. The dosing box is located inside the filter element 6, and there is a gap between the outer wall of the dosing box and the inner wall of the filter element 6. The end cap 7 includes an annular boss 71. The peripheral wall of the annular boss 71 has an inverted L-shaped groove 72. The vertical section of the L-shaped groove 72 extends to the bottom of the annular boss 71. The cover body 3 is provided with a first protrusion 31 that can slide into the L-shaped groove 72.

[0051] In use, first remove the screw-on connection between the end cap 7 and the top of the filter element 6 to separate the end cap 7 from the filter element 6. At this time, the dosing box can be pulled out. When it is necessary to add disinfectant tablets, unscrew the cap 3 from the core column 2. At this time, new disinfectant tablets can be added to the core column 2. When it is necessary to adjust the release volume of disinfectant solution, grasp the box body 1 and move the end cap 7 along the axial direction of the box body 1. The end cap 7 drives the core column 2 to move axially, so that the first through hole 12 corresponds to its set of flow holes 4.

[0052] See Figure 8 , 9 Based on the purification requirements of the filter water, the dosing box can be directly replaced to avoid using the same dosing box for different drugs, which would affect the efficacy of the drugs. When replacing, rotate the cover 3 to allow the locking block 52 to slide into or out of the L-shaped groove 72. When the locking block 52 is located in the horizontal section of the L-shaped groove 72, the cover 3 and the end cover 7 are stably connected.

[0053] The horizontal section of the L-shaped groove 72 is provided with a protrusion 73 for locking the position of the first protrusion 31. The protrusion 73 is located near the end of the horizontal section, and the end of the horizontal section cooperates with the protrusion 73 to lock the position of the first protrusion 31, further improving the connection stability between the cover 3 and the end cap 7.

[0054] Specifically, the first protrusion 31 is provided with a first inclined surface 311 near the end of the horizontal segment, which facilitates the first protrusion 31 to cross the protrusion 73 and reach the end of the horizontal segment.

[0055] Preferably, there are two first protrusions 31, which are distributed diagonally at 180° on the cover 3. Correspondingly, there are two L-shaped grooves 72, with one first protrusion 31 corresponding to one L-shaped groove 72.

[0056] Preferably, see Figure 6 The end cap 7 is provided with a handle 75 on its top to facilitate operation of the end cap 7.

[0057] In a preferred embodiment, see [reference] Figure 10 , 11The annular boss 71 has two symmetrically arranged second protrusions 74 on its peripheral wall. The filter element 6 has a top cover 8, and the top cover 8 has a shaft hole 81 in the middle. The peripheral wall of the shaft hole 81 has two steps 82 distributed diagonally at 180°. A channel 83 is provided between the beginning and end of the two steps 82 for the second protrusions 74 to pass through. The bottom of the steps 82 has an abutment surface 84 for locking the second protrusions 74. During installation, the two second protrusions 74 are inserted into the two channels 83 respectively and rotated at an angle so that the second protrusions 74 abut against the abutment surface 84. Conversely, during disassembly, the end cover 7 is rotated in the opposite direction so that the second protrusions 74 move away from the abutment surface 84 and into the channel 83, thus separating the end cover 7 from the top cover 8.

[0058] Specifically, the contact surface 84 includes a second inclined surface 841 and a plane 842 connected in sequence. The second inclined surface 841 slopes downward in the direction away from the channel 83, that is, the thickness of the step 82 gradually increases in the direction away from the channel 83. When the second protrusion 74 moves to the plane 842, the second protrusion 74 abuts against the plane 842. At this time, the connection stability between the end cover 7 and the upper cover 8 is the highest.

[0059] Further, see Figure 10 , 11 The end cap 7 has two symmetrically arranged third protrusions 76 at its bottom and two symmetrically arranged sliding grooves 85 at its top. The third protrusions 76 move within the sliding grooves 85, and the sliding grooves 85 limit the range of movement of the third protrusions 76, that is, limit the rotation angle of the end cap 7, so that the second protrusion 74 can move along the second inclined surface 841 to the plane 842, or move along the second inclined surface 841 to the channel 83.
