[0002] Faucet filters are used to filter impurities in water. However, over time, impurities and microorganisms in the water can adhere to the filter, causing odors and bacterial growth, which can affect the user's health. Although the filter is hidden inside the faucet, which maintains the faucet's aesthetics, it makes disassembly and replacement difficult. Because it is hidden inside the faucet, special tools are required to remove it. After prolonged water flow, the metal parts of the filter structure are prone to corrosion. Even with special tools, this creates significant resistance for the user's disassembly and replacement work, prolonging the disassembly time and reducing the efficiency of filter replacement.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] A faucet for easy filter replacement includes a flow guide 1. A support ring 2 is threaded onto one side of the bottom of the flow guide 1. A filter screen placement ring 3 is placed inside the support ring 2. A filter screen placement ring 4 is inserted into the top of the filter screen placement ring 3. A filter screen 5 is disposed at the bottom of the inner cavity of the filter screen placement ring 3. A filter screen 6 is disposed at the top of the inner cavity of the filter screen placement ring 4. A retaining spring 12 located above the filter screen 6 is engaged in the inner cavity of the filter screen placement ring 4. A retaining spring 10 located at the bottom of the filter screen 5 is engaged in the inner cavity of the filter screen placement ring 3. A retaining spring groove 11 adapted to the retaining spring 12 is formed on the inner wall of the filter screen placement ring 4. A retaining spring groove 9 adapted to the retaining spring 10 is formed on the inner wall of the filter screen placement ring 3.

[0029] The specific usage process is as follows: When an odor is detected in the faucet, the internal filter needs to be replaced. The user can directly use a wrench, such as an adjustable wrench or an open-end wrench, to remove the retainer ring 2 from the guide section 1. It should be noted that both sides of the retainer ring 2 have flat notches, providing a leverage point for the wrench and preventing slippage, thus assisting the user in disassembly. Wrenches are common and easy to use. The user holds the wrench on the retainer ring 2 and rotates it counterclockwise to loosen it. Threaded connections are generally loosened counterclockwise, except in special cases. In special circumstances, the user can try different operating directions until the retainer ring 2 can be removed. It should be noted that even if the retainer ring... If rust appears, generally, increasing the tightening force will resolve the issue. After removing the retainer ring 2, the filter element housed within it can be disassembled. Since the filter element is entirely contained within the retainer ring 2, traditional filter element structures require specialized tools for disassembly. Furthermore, once the metal components of the filter element rust, rust spots and rust blocks will alter the original structure. Due to the extremely narrow space within the retainer ring 2, even specialized tools lack leverage points, making filter element disassembly difficult. This solution replaces the external structure of the filter element with a non-metallic material, such as plastic. This prevents the filter element from being fixed within the retainer ring 2. Alternatively, the retainer ring 2 can be flipped over to pour it out, or a rod-shaped hard object can be used to pry the filter element structure out from within the retainer ring 2. These methods allow for easy removal of the entire filter element structure. The filter element consists of two layers with different pore sizes. This design separates the two filter layers, allowing for individual replacement. For example, severely corroded or damaged filters can be replaced individually, while unusable filters do not need to be replaced. For instance, if filter 6 is severely damaged, it can be replaced alone, while filter 5 can continue to be used without replacement, reducing maintenance costs. When replacing filter 6 or filter 5, squeeze out snap ring 10 or snap ring 22 from filter ring 3 or filter ring 4. Since snap ring 10 and snap ring 22 have the same installation method, only snap ring 22 will be explained below. When disassembling snap ring 22, squeeze the two protrusions on snap ring 22 to deform and shrink it. The small size allows the retaining ring 12 to be moved out of the retaining ring slot 11. Even if it is partially moved out, the retaining ring 12 can then be pried out of the filter screen placement ring 4 without the need for special tools; pliers are sufficient. It should be noted that retaining ring 12 and retaining ring 10 are made of metal. After removing retaining ring 12, filter screen 6 can be removed from the filter screen placement ring 4. The disassembly method for filter screen 5 is the same. It should be noted that filter screen 6 is installed on protrusion 7, and filter screen 5 is installed on protrusion 18. Filter screen placement ring 4 and filter screen placement ring 3 are interlocked using an interference fit. During installation, filter screen placement ring 4 and filter screen placement ring 3 are aligned.The snap-fit ​​angle 17 engages with the slot 8, generating friction between itself and the interior of the slot 8. This prevents the snap-fit ​​angle 17 from easily slipping out of the slot 8, ensuring a tight connection between the filter screen placement ring 2 4 and the filter screen placement ring 1 3. This provides convenience for the user. During assembly of the filter screen placement ring 1 3 and the filter screen placement ring 2 4, the snap-fit ​​angle 17 engages with the corresponding slot 8, restricting free movement of the filter screen placement ring 2 4 and the filter screen placement ring 1 3, ensuring a secure assembly and thus guaranteeing the stability of the filter element installation. To provide convenience for users and facilitate filter cartridge insertion and maintenance, protrusion 7 protrudes from the inner wall of filter screen placement ring 4. During installation, filter screen 6 is placed on protrusion 7, which supports and lifts it. Combined with retaining spring 12, this prevents filter screen 6 from moving freely under the impact of water flow. Protrusion 18, like protrusion 7, protrudes from the inner wall of filter screen placement ring 3. Filter screen 5 rests against the bottom of protrusion 18, and with retaining spring 10, it prevents filter screen 5 from sliding down under the impact of water flow. For user convenience, the external thread 13 is provided on the outer surface of the support ring 2. The outlet of the guide section 1, which is adapted to the support ring 2, is also provided with an internal thread adapted to the external thread. This allows the support ring 2 to be securely and stably installed onto the guide section 1 via a threaded connection, while also facilitating removal and providing user convenience. A portion of the bottom of the limiting ring 14 is inserted into the support ring 2 and abuts against the filter screen placement ring 4, thus confining the entire filter element within the support ring 2 and protecting it, further enhancing user convenience. The inlet pipe 15 is connected to the water supply... On the water pipe, water flows into the inlet pipe 15, passes through the guide section 1, and then flows out from the support ring 2 for use. The handle 16 is used to control the opening and closing of the faucet valve, allowing users to control the water flow on and off, providing convenience. This is existing technology. The filter screen placement ring 2 4 and filter screen placement ring 1 3 are made of non-metallic materials, ensuring that the filter screen will not easily corrode during long-term use. The filter element can be easily removed from the faucet, greatly facilitating subsequent disassembly and replacement, and providing convenience for users' work.

[0030] Therefore, a snap-fit ​​structure design is adopted, in which the filter element is directly inserted into the faucet by snapping. Since the filter element kit is made of non-metallic materials, the filter element will not rust inside the faucet. Even in a very small space, the filter element can be easily removed by disassembling the snap. Compared with the traditional filter element structure with metal parts, it is easier to remove, thereby improving the speed and efficiency of replacing the faucet filter element.

[0031] The bottom of the filter placement ring 2 4 is fixedly connected with multiple snap-fit ​​corners 17, and the surface of the filter placement ring 1 3 is provided with a slot 8 that matches the snap-fit ​​corners 17.

[0032] Specifically, the buckle angle 17 and the slot 8 are designed so that when the filter screen placement ring 1 3 and the filter screen placement ring 2 4 are assembled, the buckle angle 17 will snap into the corresponding slot 8. This not only restricts the free movement of the filter screen placement ring 2 4 and the filter screen placement ring 1 3, but also ensures the firmness of the assembly of the filter screen placement ring 1 3 and the filter screen placement ring 2 4, thereby ensuring the stability of the filter element installation, providing convenience for users, and also making it convenient for users to insert and maintain the filter element.

[0033] The inner cavity of the filter placement ring 4 is provided with a protrusion 7 of the filter 6, and the inner cavity of the filter placement ring 3 is provided with a protrusion 18 of the filter 5.

[0034] Specifically, the filter screen 2 (6), protruding platform 1 (7), filter screen 1 (5), and protruding platform 2 (18) are designed such that protruding platform 1 (7) protrudes from the inner wall of filter screen placement ring 2 (4). During installation, filter screen 2 (6) is placed on protruding platform 1 (7), which provides support and lift for filter screen 2 (6). Combined with retaining spring 2 (12), this prevents filter screen 2 (6) from moving freely under the impact of water flow. Protruding platform 2 (18), like protruding platform 1 (7), protrudes from the inner wall of filter screen placement ring 3. Filter screen 1 (5) rests against the bottom of protruding platform 2 (18). Combined with retaining spring 1 (10), this prevents filter screen 1 (5) from sliding down under the impact of water flow, providing convenience for users.

[0035] The top of the surface of the support ring 2 is provided with an external thread 13, and the inner wall of the outlet on one side of the bottom of the guide part 1 is provided with an internal thread that matches the external thread 13.

[0036] Specifically, the external thread 13 is set on the outer surface of the support ring 2. The outlet of the guide part 1 that is adapted to the support ring 2 is also provided with an internal thread that is adapted to the external thread. In this way, the support ring 2 can be firmly and stably installed on the guide part 1 through the threaded connection, and it is also easy to remove, providing convenience for users.

[0037] The top of the support ring 2 is provided with a limiting ring 14, which is located inside the flow guide 1.

[0038] Specifically, the bottom of the limiting ring 14 is designed to be inserted into the support ring 2 and abut against the filter screen placement ring 4. This design can confine the entire filter element within the support ring 2 and also protect the filter element, providing convenience for users.

[0039] One end of the flow guide 1 is connected to a water inlet pipe 15, and a handle 16 is movably installed on the top of the water inlet pipe 15.

[0040] Specifically, regarding the design of the water inlet pipe 15 and the handle 16, the water inlet pipe 15 is connected to the water supply pipe. Water flows into the water inlet pipe 15, passes through the guide section 1, and then flows out from the support ring 2 for use. The handle 16 is used to control the opening and closing of the faucet valve. In this way, the user can control the water flow by controlling the handle 16, which provides convenience for the user. This is the prior art.

[0041] Both the filter placement ring 3 and the filter placement ring 4 are made of non-metallic material, which can be PVC plastic.

[0042] Specifically, filter screen placement ring 2 (4) and filter screen placement ring 1 (3) are made of non-metallic materials, so that the filter screen will not easily rust during long-term use of the faucet. The filter element can be easily removed from the faucet, which greatly facilitates the subsequent disassembly and replacement of the filter element and provides convenience for users' work.

[0043] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
