Description

Technical Field

[0001] This utility model belongs to the field of faucets, and relates to a faucet, and more particularly to a quick-install structure for a faucet filter cartridge. Background Technology

[0002] Currently, most faucets with filter cartridges on the market connect the cartridges to the faucet body via threads. While this connection method is simple, it has obvious shortcomings. The threads are prone to wear after repeated disassembly and assembly, leading to loose connections and leaks. In addition, tightening the threads requires a certain amount of operating space and force, making the cartridge replacement process inconvenient.

[0003] Chinese patent CN218221424U discloses a convenient filter faucet for easy filter replacement, comprising a faucet body, a water outlet pipe, a filter element, a first disassembly / reassembly mechanism, a second disassembly / reassembly mechanism, and a third disassembly / reassembly mechanism. The water outlet pipe is fixedly connected to the lower end of the faucet body, and the filter element is movably installed inside the water outlet pipe. The first disassembly / reassembly mechanism is located inside the water outlet pipe, the second disassembly / reassembly mechanism is located at the outer end of the water outlet pipe, and the third disassembly / reassembly mechanism is located between the filter element and the second disassembly / reassembly mechanism. The first disassembly / reassembly mechanism includes a threaded groove, a threaded sleeve, and a connecting ring. This type of faucet has many components and a complex structure, resulting in high production costs and low assembly efficiency. The filter replacement process requires multiple steps and is cumbersome.

[0004] Therefore, there is an urgent need for a water filter faucet that is simple in structure, reliable in connection, and extremely convenient in replacing the filter cartridge. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a quick-installation structure for faucet filter cartridges, which effectively solves the problems of complex structure and inconvenient operation of existing faucets.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a quick-install structure for a faucet filter cartridge, including a main body and a water outlet pipe. The water outlet pipe is fixedly connected to the lower end of the main body, and a quick-install structure is movably installed on the water outlet pipe. The quick-install structure includes a filter cartridge and a connecting sleeve. The bottom of the water outlet pipe has an embedded part that mates with the quick-install structure. The top of the filter cartridge has a limiting ring for abutting against the water outlet pipe, and a first limiting block is provided on the limiting ring. The connecting sleeve is fitted over the filter cartridge, and its outer edge has a protrusion that mates with the embedded part. The end face of the connecting sleeve that contacts the limiting ring has a first limiting part that engages with the first limiting block. Second limiting parts that are recessed inward are provided on both sides of the protrusion. Second limiting blocks that engage with the second limiting parts are provided on both sides of the bottom end of the water outlet pipe. When the filter cartridge and the connecting sleeve are installed on the water outlet pipe, by rotating the connecting sleeve, the first limiting block and the first limiting part engage with each other, and at the same time, the second limiting block and the second limiting part engage with each other, thereby achieving axial limiting and circumferential locking of the filter cartridge on the water outlet pipe.

[0007] In the above-mentioned quick-installation structure for a faucet filter cartridge, the first limiting block is an L-shaped block, and the first limiting part is an L-shaped slot adapted to the structure of the first limiting block. This L-shaped locking structure provides a reliable circumferential anti-rotation function.

[0008] In the above-mentioned quick-release structure for a faucet filter cartridge, the second limiting part is an L-shaped slot, the second limiting block is provided with a first magnetic suction element, and the bottom of the slot of the second limiting part is provided with a second magnetic suction element that attracts the first magnetic suction element. With the help of magnetic attraction to lock, the connecting sleeve can be effectively prevented from loosening due to water flow vibration or accidental contact, thus enhancing the stability of the connection and providing a clear unlocking feel when disassembling.

[0009] In the aforementioned quick-install structure for a faucet filter cartridge, the lower end of the connecting sleeve is provided with multiple water outlet holes distributed around its circumference.

[0010] In the above-mentioned quick-install structure for a faucet filter cartridge, the first limiting part is symmetrically distributed at the four corners, and the first limiting block is symmetrically distributed at the four corners to achieve balanced force and a more reliable locking effect.

[0011] In the above-mentioned quick-install structure for a faucet filter cartridge, the second limiting part and the second limiting block are symmetrically distributed, making the structure more uniformly stressed and the limiting more reliable.

[0012] In the aforementioned quick-install structure for a faucet filter cartridge, a sealing ring is provided at the bottom end of the water outlet pipe near the inner ring of the filter cartridge.

[0013] Compared with existing technologies, the quick-installation structure for faucet filter cartridges provided by this utility model has the following advantages: through the cooperation of the limiting ring, the first limiting part and the second limiting part, the filter cartridge can be quickly installed and removed without tools; the structural cooperation between the protrusion and the embedded part ensures that the filter cartridge is installed in an accurate and unbiased position; the cooperation between the magnetic block and the magnetic part enhances the stability of the structure and prevents the filter cartridge from loosening due to water pressure fluctuations; the entire quick-installation structure is composed of multiple functionally defined parts, which are simple to process and have low cost.

Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical solution of the present invention will be further described, but the described embodiments are only some embodiments of the present invention.

[0016] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] like Figures 1 to 3 As shown, the quick-install structure 3 of the faucet filter element 31 provided by this utility model mainly consists of a body 1 and a water outlet pipe 2. The water outlet pipe 2 is connected to the lower end of the body 1, as shown in the figure. Figure 4 As shown, an annular insert 21 is formed on the inner bottom side of the water outlet pipe 2. The insert 21 is a concave annular groove, and its main function is to cooperate with the protrusion on the connecting sleeve 32 to provide initial guidance and alignment for the installation of the entire filter element 31 assembly, ensuring that the installation position is accurate and without deviation.

[0018] Multiple first limiting blocks 22 are symmetrically fixedly arranged on the outer edge of the bottom end of the water outlet pipe 2. Each first limiting block 22 is embedded with a first magnetic suction element 221. A sealing ring 4 is provided at the bottom end of the water outlet pipe 2 near the inner ring of the filter element 31. The filter element 31 is a conventional filter element with a radially outward extending limiting ring 311 at its top. The limiting ring 311 is usually made of relatively hard plastic. When the filter element 31 is installed in place, the upper surface of its upper limiting ring 311 is in close contact with the bottom end face of the water outlet pipe 2. This not only plays a preliminary axial limiting role, but also achieves a reliable static seal by setting the sealing ring 4 on the contact surface, preventing unfiltered water from flowing out from the gap. Multiple second limiting blocks 312 are evenly distributed along its circumference on the upper end face of the limiting ring 311. In this embodiment, the second limiting block 312 is preferably an L-shaped structure, including a guide section and a locking section.

[0019] like Figure 5 and Figure 6 As shown, the connecting sleeve 32 is a key component. The connecting sleeve 32 is fitted onto the outside of the filter element 31, and its inner diameter is adapted to the outer diameter of the filter element 31. It can rotate relative to the filter element 31 without being too loose. The outer edge of the connecting sleeve 32 protrudes to form a protrusion 322. The shape and size of the protrusion 322 match the embedding part 21 at the bottom of the water outlet pipe 2, so that the protrusion 322 can be smoothly inserted into the embedding part 21. The upper end face of the connecting sleeve 32 is provided with a plurality of first limiting parts 323 that correspond one-to-one with the first limiting blocks 22 on the filter element 31 and are adapted in shape. The first limiting part 323 is also an L-shaped groove. On both sides of the first limiting part 323, there are inwardly recessed second limiting parts 325. The second limiting part 325 is also an L-shaped groove structure with its entrance facing downward, so as to facilitate the entry of the second limiting block 312, so as to achieve balanced force and a more reliable locking effect.

[0020] A second magnetic element 324 is embedded in the bottom of the groove of the second limiting part 325. The magnetic attraction helps to lock the connection sleeve 32, which can effectively prevent the connection sleeve 32 from loosening due to water flow vibration or accidental contact, thus enhancing the stability of the connection and providing a clear unlocking feel when disassembling.

[0021] In addition, the lower end of the connecting sleeve 32 is provided with multiple water outlet holes. Water purified by the filter element 31 will flow out evenly and dispersedly through these water outlet holes, forming a gentle water flow.

[0022] The working principle of this utility model is as follows: The filter element 31 is placed into the connecting sleeve 32, and the first limiting block 22 on the top of the filter element 31 is aligned with the first limiting part 323 on the connecting sleeve 32 and pushed in. At this time, the filter element 31 and the connecting sleeve 32 are combined into an independent quick-installation structure 3 assembly. This quick-installation structure 3 assembly is pushed upward into the outlet 321, so that the protrusion of the connecting sleeve 32 is aligned with the embedded part 21 of the outlet pipe 2 and abuts against it. Then, the connecting sleeve 32 is rotated, and two locking actions are completed simultaneously: the first limiting block 22 on the filter element 31 slides into the bottom of the first limiting part 323 of the connecting sleeve 32 to achieve internal locking, and the second limiting block 312 on the outlet pipe 2 slides into the bottom of the second limiting part 325 of the connecting sleeve 32. At the same time, the first magnetic suction member 221 and the second magnetic suction member 324 are attracted to achieve external locking and anti-loosening. When disassembling, it is only necessary to rotate the connecting sleeve 32 in the opposite direction to overcome the magnetic force and then remove the entire quick-installation structure 3 assembly. The filter element replacement process is quick and labor-saving.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
