Description

Technical Field

[0001] This utility model relates to the field of filtration and purification equipment, specifically to a filter element installation assembly and a filter element. Background Technology

[0002] In the field of water treatment, using filter cartridges to filter impurities and purify water is a common method. The ease of installation and replacement of filter cartridges directly affects the operating efficiency and maintenance costs of water treatment equipment. Current filter cartridge installation methods require installing the cartridge onto a compatible filtration device. The installation and disassembly process is cumbersome and requires professional operation. For example, specific installation structures are used for fixing, followed by tools for installation and disassembly. Alternatively, a screw-on snap-fit ​​structure is used, where the cartridge is aligned with the designated position by rotating it. However, these installation methods are inconvenient in practice, time-consuming, and require a high level of operator skill. Improper operation can lead to insecure installation or damage to the filter cartridge, affecting the normal operation and lifespan of the entire water treatment equipment. Furthermore, these installation and disassembly processes increase equipment maintenance costs and downtime, as well as labor and time costs.

[0003] To address the aforementioned problems in the existing technology, there is a need to provide a filter element installation assembly that is simpler in structure and easier to install and disassemble. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a filter element installation assembly and a filter element, which can effectively solve the problem of low efficiency in the filter element disassembly and installation methods in the aforementioned existing technologies.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The first aspect of this utility model provides a filter element mounting assembly, comprising:

[0007] Guide bracket;

[0008] A slider, which is retractably disposed in the guide bracket, and a portion of the slider can extend out of the outside of the guide bracket;

[0009] A button linkage is slidably disposed in the guide bracket, and the button linkage abuts against the slider; wherein the button linkage can be confined in the guide bracket to lock the slider.

[0010] When the button linkage is pressed for the first time, the slider retracts or extends along the guide bracket; when the button linkage is pressed for the second time, the slider returns to its original position.

[0011] In some implementations, it also includes:

[0012] A rotating ring, which is rotatably disposed in the button linkage,

[0013] A button push plate, which is connected to the button connecting rod;

[0014] The button push plate is subjected to force, which drives the button connecting rod to press and move, and the button push plate pushes the rotating ring to rotate, so that the button connecting rod can be engaged or disengaged from the rotating ring.

[0015] In some embodiments, the rotating ring is provided with a first retaining tooth, and the button push plate is provided with a push plate retaining tooth. When the button push plate is pressed, it drives the push plate retaining tooth, and the push plate retaining tooth abuts against and pushes the first retaining tooth, causing the rotating ring to rotate.

[0016] In some embodiments, the rotating ring is provided with a second locking tooth, and the button linkage is provided with a connecting rod locking tooth. The connecting rod locking tooth engages with the second locking tooth to lock the pressing position of the button linkage.

[0017] In some embodiments, one end of the guide bracket has a spring bracket, the spring bracket is sleeved with a first elastic element, the first elastic element abuts against the button push plate, and the button push plate is reset by the elastic force of the first elastic element.

[0018] In some embodiments, a second elastic element is also included that abuts against the button link. The button link extends and retracts through the elastic force of the second elastic element to drive the link teeth to abut against and push the second teeth, thereby causing the rotating ring to rotate.

[0019] In some embodiments, the spring support is fitted with a third elastic element, which abuts against the slider, and the slider is reset by the elastic force of the third elastic element.

[0020] In some embodiments, a filter cartridge seat is also included, the guide bracket is connected to the filter cartridge seat, and a portion of the slider extends outward from the outer side of the filter cartridge seat via the guide bracket.

[0021] In some embodiments, the filter cartridge seat is connected to a filter cartridge cover, the filter cartridge cover rotatably supports the rotating ring, and the button linkage and the button push plate are telescopically mounted on the filter cartridge cover.

[0022] On the other hand, the present invention provides a filter element, including the filter element mounting assembly described in the first aspect, and also includes a filter bottle, wherein the filter bottle has filter media, and the filter bottle is connected to the filter cartridge seat.

[0023] Compared with the prior art, the filter element mounting assembly and filter element of this utility model have the following advantages:

[0024] This application features a retractable slider housed within a guide bracket, and a slidable button linkage also housed within the guide bracket. When the button linkage is pressed for the first time, it causes the slider to retract into the guide bracket. A second press causes the slider to reset. Thus, the extension and retraction of the slider section can be achieved through two presses of the button linkage. The slider's structure allows for engagement with external filtration equipment; one press unlocks the slider, and two presses reset it. The process is simple and convenient, requiring no specialized tools or complex screw-on engagement mechanisms from professionals. This effectively improves the efficiency of filter element installation and removal, reduces the skill requirements for operators, and avoids problems such as insecure or damaged filter elements due to improper operation. Furthermore, the simple structure of this filter element installation component reduces equipment maintenance costs and downtime, lowering labor and time costs. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] See Figures 1 to 16 The present invention discloses a filter element mounting assembly 1 and a filter element. The filter element mounting assembly 1 includes a filter cartridge seat 11, a filter cartridge cover 12, a guide bracket 13, a slider 14, a button connecting rod 15, a rotating ring 16, a button push plate 17, and a spring bracket 18.

[0047] like Figure 3 and Figure 5 As shown, the filter cartridge seat 11 and filter cartridge cover 12 are cylindrical in shape. The filter cartridge seat 11 and filter cartridge cover 12 are detachably connected to form a hollow structure that can accommodate other components. The guide bracket 13, slider 14, button connecting rod 15, rotating ring 16, button push plate 17 and spring bracket 18 are surrounded inside. It should be noted that in this embodiment, part of the structure of the slider 14 can extend out of the filter cartridge seat 11 and filter cartridge cover 12. The filter cartridge seat 11 and filter cartridge cover 12 can be reserved with a notch for the slider 14 to extend out, so that it can be detachably connected to external filtration equipment (e.g., snap-fit). The external filtration equipment can provide a slot structure that is compatible with the slider 14 for snap-fit. After the filter cartridge seat 11 and filter cartridge cover 12 are assembled, they can be installed into the filtration equipment.

[0048] like Figure 4 , Figure 5 and Figure 6 As shown, the guide bracket 13 is used to guide and support other components. It is an overall circular disc shape and is installed inside the filter cartridge seat 11. The guide bracket 13 can be connected to the filter cartridge seat 11 by screws or bolts. The center of the guide bracket 13 has a hollow design to provide suitable space for the movement of the button linkage 15. The guide bracket 13 has a first guide port 131, a second guide port 132, and a third guide port 133 on both sides. These three guide ports are arranged in pairs. The first guide port 131 is closer to the center of the guide bracket 13 than the second guide port 132. The first and third guide ports 131 and 133 abut against and guide the button linkage 15, causing it to move in a specific direction. The third guide port 133 is spaced apart from the first guide port 131. The second guide port 132 allows the slider 14 to slide and extend, thus limiting the direction of movement of the slider 14. Preferably, the first guide port 131 and the second guide port 132 are located in the same radial direction of the guide bracket 13.

[0049] like Figure 4 , Figure 5 and Figure 7 As shown, the button linkage 15 is slidably disposed in the guide bracket 13, and the button linkage 15 can be confined in the guide bracket 13 by a snap-fit ​​structure. The button linkage 15 can slide along the axial direction of the guide bracket 13 (or filter cover 12), which is also the direction in which the button linkage 15 is pressed. The button linkage 15 has a linkage abutment 151, a linkage protrusion 152, and a linkage mounting part 153. The linkage abutment 151 and the linkage protrusion 152 are disposed opposite to each other. The linkage abutment 151 is a structure that extends along the guide bracket 13. The inner side of the linkage abutment 151 has an arc or bevel structure that can abut against the slider 14. The number of linkage abutment 151 corresponds to the number of sliders 14. The linkage abutment 151 abuts against the first guide opening 131 and can slide along the first guide opening 131. The connecting rod protrusion 152 is positioned opposite to the connecting rod abutment 151, and the direction of the protrusion is opposite to that of the connecting rod abutment 151. Multiple connecting rod protrusions 152 can be provided, primarily for insertion into the button push plate 17 to increase the connection strength. The connecting rod mounting part 153 is located on the same side as the connecting rod abutment 151 and overlaps with it. The connecting rod mounting part 153 is inserted into the guide bracket 13 through the third guide port 133. The connecting rod mounting part 153 is used to sleeve or abut against the second elastic element 1b, which is specifically a spring. The other end of the second elastic element 1b abuts against the bottom surface of the filter cartridge seat 11, giving the button connecting rod 15 a restoring elastic force.

[0050] like Figure 6 and Figure 9 As shown, the slider 14 is slidably and telescopically disposed in the guide bracket 13. The slider 14 is specifically inserted into the second guide port 132. In this embodiment, two sliders 14 are provided; in other embodiments, multiple sliders can be used, depending on actual needs. The slider 14 has a sliding abutment portion 141 and a sliding protrusion 142, which are disposed opposite to each other. The sliding abutment portion 141 is located inside the guide bracket 13 and has an arc or bevel structure, enabling it to abut against the connecting rod abutment portion 151. A notch is provided between the sliding abutment portion 141 and the sliding protrusion 142, providing sufficient space for the connecting rod abutment portion 151 when it pushes the sliding abutment portion 141. Figure 10 As shown, the sliding protrusion 142 can slide and extend along the second guide port 132. The sliding protrusion 142 can extend out of the outer side of the filter cartridge seat 11 (and the guide bracket 13). The end of the sliding protrusion 142 also has a guide slope structure, which can be quickly snapped into the slot (not used) of the external filter device.

[0051] like Figure 5 , Figure 7 and Figure 9 As shown, the rotating ring 16 is rotatably mounted in the button linkage 15. Specifically, the button linkage 15 has a hollow circular hole at its center, and the rotating ring 16 is mounted in the central circular hole of the button linkage 15. The rotating ring 16 is cylindrical in shape, with a hollow internal structure and through-holes at both ends. Part of the filter cartridge cover 12 extends into the inner wall of the rotating ring 16, providing positioning and support for the rotating ring 16. One side of the rotating ring 16 abuts against the guide bracket 13, allowing the rotating ring 16 to rotate on one side of the guide bracket 13. The rotating ring 16 has a first locking tooth 161 and a second locking tooth 162, which are arranged opposite each other in the axial direction of the rotating ring 16. The first locking tooth 161 is designed around the rotating ring 16 to form a continuous tooth structure, and the first locking tooth 161 is a protruding tooth structure with a beveled surface. The second locking tooth 162 is integrally formed with the first locking tooth 161. The second locking tooth 162 forms a structure with a groove through the inclined teeth. There is a gap between adjacent second locking teeth 162, so that a limiting opening 163 is formed between adjacent second locking teeth 162.

[0052] Among them, such as Figure 7As shown, the button link 15 is provided with a link retaining tooth 154. The link retaining tooth 154 is located on the side wall of the central circular hole of the button link 15 and is evenly distributed in a circular pattern. The link retaining tooth 154 has an inclined surface, which is located on the side of the link protrusion 152. The width of the limiting opening 163 is adapted to the width of the link retaining tooth 154, so that the link retaining tooth 154 can slide along the limiting opening 163. When the rotating ring 16 rotates, the link retaining tooth 154 can abut against the second retaining tooth 162, and the inclined surface structure allows the link retaining tooth 154 to push the second retaining tooth 162, thereby causing the rotating ring 16 to rotate further, so that the link retaining tooth 154 can engage with the groove of the second retaining tooth 162, thereby completing the temporary locking of the button link 15. Therefore, the button link 15 (link abutting part 151) can be temporarily limited in the guide bracket 13 and held in a specific position to lock the sliding position of the slider 14.

[0053] like Figure 8 As shown, the button push plate 17 is used to receive external force to push the button linkage 15 to move. The button push plate 17 has a disc-shaped shape and a push plate slot 171 for the linkage protrusion 152 to be inserted. After the linkage protrusion 152 is inserted into the push plate slot 171, the button push plate 17 can be inserted into the button linkage 15. The button push plate 17 also has a cylindrical structure for being inserted into the filter cover, which can play a positioning role for the button push plate 17, so that the linkage protrusion 152 and the push plate slot 171 can be accurately inserted. The button push plate 17 has push plate teeth 172 on its inner side opposite to the push plate slot 171. The structure of the push plate teeth 172 corresponds to the structure of the first teeth 161. The push plate teeth 172 also have protruding teeth with an inclined surface, facing the first teeth 161. When the button push plate 17 is subjected to force, it drives the button connecting rod 15 to press and move, causing the push plate teeth 172 to abut against the first teeth 161. The inclined surface structure causes the push plate teeth 172 to push the first teeth 161, thereby causing the rotating ring 16 to rotate. Therefore, the button push plate 17 is mainly used to receive external force and drive the rotating ring 16 to rotate. The button push plate 17 also has a push plate protrusion 173 at its center. The push plate protrusion 173 extends along the direction of the rotating ring 16 and can be inserted into the central annular hole of the rotating ring 16. In addition, a button cover 19 is fitted onto the end of the button push plate 17, which is compatible with the shape of the filter cartridge cover 12, making the housing of the entire mounting assembly more complete.

[0054] like Figure 9As shown, the spring bracket 18 is detachably mounted on the filter cartridge seat 11 and located at the center of the guide bracket 13. It is used to mount the first elastic element 1a and the third elastic element 1c. The first elastic element 1a and the third elastic element 1c are specifically springs. The first elastic element 1a is sleeved on one end of the spring bracket 18 and abuts against the push plate protrusion 173, so that the button push plate 17 has a restoring elastic force. The extension and retraction direction of the first elastic element 1a is the same as the pressing direction of the button push plate 17 (the extension and retraction direction of the second elastic element 1b). There are two third elastic elements 1c, which are arranged opposite each other and act on the slider 14. One end of the third elastic element 1c is sleeved on the side of the spring bracket 18, and the other end abuts against the slider 14, specifically against the opposite side of the sliding abutment part 141. The extension and retraction direction of the third elastic element 1c is orthogonal to the extension and retraction direction of the first elastic element 1a. It can be seen that when the button linkage 15 is pressed, it drives the linkage abutment part 151 to push the sliding abutment part 141 to move, so that the sliding abutment part 141 compresses the third elastic element 1c, providing the slider 14 with the elastic force to reset.

[0055] This utility model also provides a filter element, which includes the aforementioned filter element mounting assembly 1 and filter bottle 21. The end of the filter bottle 21 can be connected to the filter cartridge base 11. Filter media 22 is installed inside the filter bottle 21, and a top cover 24 and a bottom cover 23 are installed at both ends of the filter media 22. After assembly of the aforementioned components, a complete filter element is formed and can be installed in a filtration device. When the filter element is installed in the filtration device, such as... Figure 9 As shown, the sliding protrusion 142 of the slider 14 is in a state of extending outward from the filter cartridge cover 12 under the action of the third elastic element 1c. When the entire filter element is installed, the sliding protrusion 142 can be engaged with the slot of the filter equipment by the elastic force of the third elastic element 1c. When the button push plate 17 is pressed, the button push plate 17 and the button connecting rod 15 are pressed and moved for the first time, as shown. Figure 10 As shown, under the action of the rotating ring 16 and the button push plate 17, the button connecting rod 15 can be confined in the guide bracket 13 to lock the slider 14, so that the sliding protrusion 142 retracts into the guide bracket 13 and the filter element can be removed; when the button push plate 17 and the button connecting rod 15 are pressed and moved for the second time, the button connecting rod 15 is unlocked, and the slider 14 extends to the filter cartridge cover 12 under the action of the third elastic element 1c, thus completing the disassembly and installation of the filter element in sequence.

[0056] Of course, in other embodiments, the limiting effect of the button linkage 15 is not limited to the rotating ring 16 and the button push plate 17. It can also be achieved by setting a pressing and rotating snap-fit ​​structure in the guide bracket 13, and cooperating with the linkage abutment part 151 to temporarily limit and lock the slider 14.

[0057] The following describes the operation process of filter element installation assembly 1. In the initial state, as follows: Figure 11As shown, at this time, under the action of the third elastic element 1c, the sliding protrusion 142 of the slider 14 extends out of the outside of the filter cartridge cover 12 and is in a position that can be engaged with the slot of the external filtration equipment. The filter element is in a state of waiting to be installed or has been stably installed (if it has been engaged in the filtration equipment). The pressing state mainly includes four actions:

[0058] The first action: such as Figure 12 As shown, when the button push plate 17 (or button cover 19) is pressed for the first time, the button push plate 17 is forced to slide the button connecting rod 15 in the axial direction. The connecting rod tooth 154 slides along the limiting port 163 of the rotating ring 16. The push plate tooth 172 abuts against the first tooth 161 of the rotating ring 16. The first tooth 161 is pushed by the inclined structure, causing the rotating ring 16 to rotate. At this time, the first elastic element 1a and the second elastic element 1b are compressed. The connecting rod tooth 154 has disengaged from the limiting port 163, and the second tooth 162 has not yet abutted against the connecting rod tooth 154. At the same time, the connecting rod abutting part 151 of the button connecting rod 15 pushes the sliding abutting part 141 of the slider 14. The slider 14 retracts into the guide bracket 13, and the sliding protrusion 142 also retracts. The third elastic element 1c is gradually compressed.

[0059] The second action: such as Figure 13 As shown, when the button push plate 17 is released, the button push plate 17 and the button connecting rod 15 are no longer under force. Under the elastic force of the first elastic element 1a and the second elastic element 1b, the button push plate 17 and the button connecting rod 15 tend to reset. At this time, the connecting rod retaining tooth 154 abuts against the second retaining tooth 162, and the connecting rod retaining tooth 154 pushes the first retaining tooth 161 through the inclined structure, causing the rotating ring 16 to rotate. The connecting rod retaining tooth 154 finally engages with the groove of the second retaining tooth 162, completing the temporary locking of the button connecting rod 15, keeping the slider 14 retracted into the guide bracket 13, and the third elastic element 1c is still compressed. At this time, the filter element can be removed from the filtration device.

[0060] The third action: such as Figure 14 As shown, when the button push plate 17 (or button cover 19) is pressed for the second time, the button push plate 17 is forced to slide the button connecting rod 15 in the axial direction. The first elastic element 1a, the second elastic element 1b and the third elastic element 1c are still in a compressed state. The connecting rod retaining tooth 154 disengages from the second retaining tooth 162 until the push plate retaining tooth 172 abuts against the first retaining tooth 161. The first retaining tooth 161 is pushed by the inclined structure, causing the rotating ring 16 to rotate. In contrast, the second retaining tooth 162 is displaced relative to the connecting rod retaining tooth 154.

[0061] The fourth action: such as Figure 15 and Figure 16As shown, when the button push plate 17 is released, under the elastic force of the first elastic element 1a and the second elastic element 1b, the button push plate 17 and the button connecting rod 15 move to reset, causing the connecting rod retaining tooth 154 to abut against the second retaining tooth 162. The connecting rod retaining tooth 154 pushes the first retaining tooth 161 through the inclined structure, causing the rotating ring 16 to rotate again. The connecting rod retaining tooth 154 gradually resets and the other limiting port 163 gradually approaches the connecting rod retaining tooth 154 until the connecting rod retaining tooth 154 slides in the limiting port 163. At this time, the button push plate 17 and the button connecting rod 15 reset to their original initial positions, the slider 14 is unlocked, and under the elastic force of the third elastic element 1c, the slider 14 is pushed out by the third elastic element 1c. The sliding protrusion 142 extends to the outside of the filter cover and returns to the initial snap-fit ​​state, thus completing the disassembly and reinstallation preparation of the filter element.

[0062] This utility model has the following advantages: It features a compact and ingenious structure, allowing for easy and quick installation and removal of the filter element through a simple pressing operation. It is multifunctional and highly practical; users can easily remove or reinstall the filter element from the filtration equipment by simply pressing the push plate 17 twice, greatly improving work efficiency. It is highly adaptable and widely applicable; due to the versatility of the filter element installation assembly 1's structural design, the size and shape of each component can be adjusted according to different actual needs. This assembly can be applied to various types of filtration equipment and filter elements, and has broad market application prospects.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
