Description

Technical Field

[0001] This utility model relates to the field of water dispenser filter cartridges, and in particular to a filter assembly and a quick-installation structure for the filter cartridge. Background Technology

[0002] The filter cartridge is one of the core components of a filtration system. Existing water dispensers, especially commercial ones, typically have a snap-fit ​​mounting position and inlet for the filter cartridge on their side wall. This inlet uses a traditional screw-on connection. However, during actual installation, it was found that the existing snap-fit ​​position, located directly below the inlet (ensuring the filter cartridge body is fully engaged after tightening), interferes with the rotation of the filter cartridge during tightening. Since filter cartridges are consumables in water dispensers and need frequent replacement to ensure filtration effectiveness, this interference with rotation during tightening makes filter cartridge replacement difficult. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a filter component and a quick-installation structure.

A top sealing ring is provided in the top sealing ring groove, and a bottom sealing ring is provided in the bottom sealing ring groove. The bottom sealing ring is placed on the side wall below the water outlet. When the filter cap is inserted into the base, a water inlet gap is formed between the top of the filter cap and the bottom of the insertion hole, which is connected to the water inlet channel. The top sealing ring is used below the water inlet gap to block the passage between the water inlet gap and the water outlet. When the filter cap is inserted into the base, the bottom sealing ring seals the water outlet channel below the filter cap and is placed between the side wall of the insertion hole and the filter cap to seal the gap between the side wall of the insertion hole and the filter cap.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0012] Reference Figure 1-6 A quick-installation filter element structure includes a locking and rotating assembly. The rotating assembly is located on the outer wall of the filter element locking assembly, and the filter element locking assembly rotates around the rotating assembly. In use, the rotating assembly is actually installed on the side wall of the water dispenser, allowing the filter element locking assembly to move closer to or further away from the side wall. When the filter element needs to be removed, it can be rotated to a direction perpendicular to the side wall of the water dispenser for easy removal and replacement. After replacement, rotating the filter element again will allow it to fit snugly against the side wall of the water dispenser without affecting its use. Simultaneously, rotating it to a direction perpendicular to the side wall of the water dispenser provides more operating space, making removal and replacement more convenient. In this embodiment, the filter element locking assembly includes a base 1 and a filter element cap 2, with the rotating assembly located on the outer wall of the base 1. Specifically, the rotating assembly can be installed by perforating the side wall of the base 1, with a hollow rotating shaft 13 inserted through the hole; that is, the rotating shaft serves as the rotating assembly. The hollow rotating shaft 13 has a pipe connected to the inlet channel 9 and the outlet channel 10. When the rotating shaft is connected to the side wall of the water dispenser, the base 1 can rotate, up to a position perpendicular to the side wall of the water dispenser. This provides a wider operating range for disassembling and replacing the filter element, making disassembly and replacement more convenient.

[0013] In this embodiment, the filter cap 2 is fitted and fixed onto the filter body 14. The base 1 has an insertion hole for inserting the filter cap 2. A positioning ring groove 3 and a locking ring groove 4 are formed on the side wall of the insertion hole. A limiting ridge 6 protrudes outward from the outer wall of the filter cap 2 corresponding to the position of the positioning ring groove 3. A locking boss 5 is provided on the outer wall of the filter cap 2 corresponding to the position of the locking ring groove 4. The surface of the locking boss 5 can be curved, allowing the filter body 14 to tighten as it rotates, eventually pressing against the base 1. Specifically, a locking ring groove 4, adapted to the locking boss 5, is formed on the side wall of the insertion hole. The locking ring groove 4 is an inverted L-shape. When the filter cap 2 is inserted into the insertion hole, the locking boss 5 is inserted through the vertical portion of the locking ring groove 4. When the filter cap 2 rotates within the locking ring groove 4, the locking boss 5 moves through the horizontal portion of the locking ring groove 4. With rotation, the filter body 14 becomes increasingly tight, resulting in better sealing performance in addition to good contact.

[0014] A water inlet hole 7 is provided at the center of the top of the filter cap 2, which communicates with the filter body 14. A water outlet hole 8 is provided on the side wall of the filter cap 2. The water outlet hole 8 is annular. A water inlet channel 9 and a water outlet channel 10 are provided on the side wall of the base 1. When the filter cap 2 is inserted into the base 1, the water inlet channel 9 communicates with the water inlet hole 7, and the water outlet channel 10 communicates with the water outlet hole 8. The water inlet channel 9, the water outlet channel 10 and the rotation axis of the base 1 are coaxial. Specifically, a bottom sealing ring groove and a top sealing ring groove are provided on the outer wall of the filter cap 2. The bottom sealing ring groove is parallel to the top sealing ring groove. A top sealing ring 11 is provided in the top sealing ring groove, and a bottom sealing ring 12 is provided in the bottom sealing ring groove. The bottom sealing ring 12 is placed on the side wall below the water outlet hole 8. When the filter body 14 is installed, as it is screwed, the top sealing ring 11 and the bottom sealing ring 12 are pressed against the base 1, which achieves a sealing effect.

[0015] In this embodiment, when the filter cap 2 is inserted into the base 1, a water inlet gap is formed between the top of the filter cap 2 and the bottom of the insertion hole, which is connected to the water inlet channel 9. The top sealing ring 11 is located below the water inlet gap to block the passage between the water inlet gap and the water outlet hole 8. When the filter cap 2 is inserted into the base 1, the bottom sealing ring 12 is located below the water outlet channel 10 and is placed between the side wall of the insertion hole and the filter cap 2 to block the gap between the side wall of the insertion hole and the filter cap 2. When the water flows out from the water outlet hole 8, it flows into the water outlet channel 10 through the gap between the top sealing ring 11 and the bottom sealing ring 12.

[0016] In practical use, a filtration assembly typically consists of three sets of filter cartridges. Specifically, in this embodiment, the filtration assembly is composed of multiple quick-connect filter cartridges connected in series. The inlet channel 9 of the quick-connect filter cartridge assembly is interconnected with the outlet channel 10 of the adjacent quick-connect filter cartridge assembly via a pipe. When tap water flows in, it passes through the three sets of filter cartridges in sequence for filtration and purification to obtain clean water. When replacing the filter cartridges, they can be rotated to a direction perpendicular to the side wall of the water dispenser for easy removal and replacement. After replacement, rotating the filter cartridges again allows them to fit snugly against the side wall of the water dispenser without affecting operation. Furthermore, rotating the filter cartridges to a direction perpendicular to the side wall of the water dispenser provides greater operating space, making removal and replacement more convenient.

[0017] Compared to existing technologies, the rotating component of this invention is actually installed on the side wall of the water dispenser, allowing the filter cartridge engaging component to be closer to or further away from the side wall of the water dispenser. When the filter cartridge needs to be disassembled or installed, it can be rotated to a direction perpendicular to the side wall of the water dispenser to obtain more operating space, which facilitates the disassembly and replacement of the filter cartridge. After replacement, the filter cartridge can be rotated again to make it fit against the side wall of the water dispenser without affecting its use.

[0018] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
