[0002] With economic development and improved living standards, consumers are paying more and more attention to healthy water and drinking water, and their requirements for water use are also getting higher and higher. As a device that can filter and purify raw water such as tap water, especially faucet water purifiers that can be fixed at water pipes or faucets and directly filter impurities in the water as it flows out, water purifiers are gaining increasing recognition and favor from consumers.

[0003] There are many types of faucet water purifiers available, but most commonly used faucet water purifiers consist of a casing and a filter cartridge housed inside the casing. Over time, filtration in faucet water purifiers can lead to a buildup of filtered dirt on the outside of the filter cartridge, reducing its filtration efficiency and effectiveness. To address this issue, a scraping mechanism is typically installed on the outside of the filter cartridge for rotating and cleaning. This scraping mechanism uses brushes to clean the outer surface of the filter cartridge during rotation. However, most faucet water purifiers with scraping mechanisms require manual rotation, which is inconvenient, inefficient, and yields poor cleaning results. Utility Model Content

[0044] Combination Figures 1-10 As shown, this utility model provides a water-driven scraping type water purifier faucet, including a housing 1, a base 2, a filter element assembly 3, and a water-driven scraping assembly 4. The upper end of the housing 1 has a water inlet 101, and the lower end of the housing 1 is detachably fitted with the base 2. The detachable base 2 facilitates the installation and removal of the filter element assembly 3. The base 2 has a water outlet 201, and the water inlet 101, the water-driven scraping assembly 4, the filter element assembly 3, and the water outlet 201 are arranged coaxially. This structure, with its detachable base design, facilitates cleaning of dirt generated by the water-driven scraping assembly, and the filter element assembly is inserted into the base, making it easy to install, remove, and replace.

[0045] See Figures 3 to 6 The filter element assembly 3 is placed inside the housing 1, and its lower end is detachably inserted into the base 2 and communicates with the water outlet 201. The water-driven scraping assembly 4 is coaxially arranged with the water inlet 101 and is used to perform rotary scraping of the filter element assembly 3. The water-driven scraping assembly 4 includes a water-driving component 41 arranged near the water inlet 101 and a rotating impeller 42 supported on the upper end of the filter element assembly 3 and capable of rotation. The water-driving component 41 changes the direction of water flow to create a swirling effect, allowing the water flow to drive the rotating impeller 42 to rotate. Multiple spiral water-driving channels 411 are arranged annularly on the water-driving component 41, allowing water to drive the rotating impeller 42 to rotate after passing through the spiral water-driving channels 411. At least one cleaning brush 43 is connected to the lower side of the rotating impeller 42, and the cleaning brush 43 is used to scrape the outer circumferential wall of the filter element assembly 3. During water-driven scraping, water enters from the inlet 101, then drives the rotating impeller 42 to rotate through the spiral water-driving channel 411. The rotating impeller 42 drives the cleaning brush 43 to rotate, and the cleaning brush 43 rotates around the filter element assembly 3 and scrapes the outer circumferential wall of the filter element assembly 3. Finally, the water flows out from the outlet hole 201 after being filtered by the filter element assembly 3.

[0046] This structure adds a water-driven scraping component. Through the cooperation of the water-driving component, the rotating impeller and the cleaning brush, water can drive the rotating impeller to rotate after passing through the spiral water-driving channel. The rotating impeller drives the cleaning brush to scrape the outer circumferential wall of the filter element assembly, so that the filter element assembly can be automatically scraped continuously without manual operation. It is convenient to use and has a good cleaning effect.

[0047] In some embodiments, such as Figure 2 , Figure 9 and Figure 10 As shown, a flushing insertion groove 202 is recessed in the base 2. When the filter element assembly 3 becomes dirty after a period of use, the base 2 can be removed, the rotating impeller 42 can be taken out, and the filter element assembly 3 can be pulled out from the base 2, thus removing the filter element assembly 3. After the filter element assembly 3 is removed, the insertion end of the filter element assembly 3 can be inserted into the flushing insertion groove 202 and communicate with the water outlet 201. At this time, water enters from the water inlet 101 and flows out from the water outlet 201, thereby achieving backwashing of the filter element assembly 3. The insertion end of the filter element assembly 3 is the end that is inserted into the base 2. In this structure, the filter element adopts a detachable design and a flushing insertion groove is added. When the filter element assembly is removed, the insertion end of the filter element assembly can be inserted into the flushing insertion groove, thereby achieving backwashing of the filter element assembly, further improving the cleaning effect, which is conducive to extending the service life of the filter element assembly and reducing the operating cost.

[0048] In some embodiments, such as Figure 3 , Figure 4 and Figure 10As shown, an annular connecting part 203 protrudes from the inner wall of the base 2, and the annular connecting part 203 and the base 2 are an integral structure.

[0049] The annular connecting part 203 is provided with a filter insertion groove 204 adapted to the insertion end of the filter element assembly 3; wherein, the annular connecting part 203, the filter insertion groove 204, and the rinsing insertion groove 202 are arranged coaxially. The insertion end of the filter element assembly 3 is fitted with a first sealing ring 5; the use of the first sealing ring 5 ensures the sealing of the connection between the filter element assembly 3 and the filter insertion groove 204 or the rinsing insertion groove 202, and the elasticity of the first sealing ring 5 allows for plug-in and pull-out connection between the filter element assembly 3 and the inner wall of the filter insertion groove 204 or the rinsing insertion groove 202, resulting in a simple structure and stable function. The base 2 is threadedly connected to the housing 1 for easy assembly and disassembly; a second sealing ring 6 is installed between the housing 1 and the base 2 to ensure the sealing of the connection between the housing 1 and the base 2.

[0050] In some embodiments, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the support end of the filter element assembly 3 is provided with an annular flange 301, and a shaft hole 302 is formed in the center of the annular flange 301; wherein, the support end of the filter element assembly 3 is the end that supports the rotating impeller 42. The rotating impeller 42 is provided with an annular groove 421 adapted to the annular flange 301 and a support shaft 422 adapted to the shaft hole 302. The annular flange 301 is placed in the annular groove 421, and the support shaft 422 is placed in the shaft hole 302; with this structure, the support end of the filter element assembly 3 can stably support the rotating impeller 42, so that it can rotate stably within the housing 1.

[0051] In some embodiments, such as Figure 1 as well as Figures 3 to 5 As shown, the water-driving component 41 has multiple buckles 411 arranged in a ring at equal intervals. The buckles 411 and the water-driving component 41 are integrally designed plastic parts, giving the buckles 411 a certain degree of elasticity. The water inlet 101 has multiple slots 102 that can engage with the buckles 411. The buckles 411 can be inserted into the slots 102, thus achieving a secure connection between the water-driving component 41 and the housing 1. The water inlet 101 has a threaded portion 103, which is an internal thread within the water inlet 101. This threaded portion 103 can be threaded to an external water pipe or faucet for easy assembly and disassembly.

[0052] In some embodiments, such as Figure 3 , Figure 6 and Figure 7As shown, a brush holder 44 is connected to the lower side of the rotating impeller 42, and the cleaning brush 43 is installed on the brush holder 44 by a snap-fit ​​method. When the rotating impeller 42 rotates, the rotating impeller 42 drives the brush holder 44 to rotate, and the brush holder 44 drives the cleaning brush 43 to rotate. A water-blocking ring 423 is provided at the upper center of the rotating impeller 42. Multiple blades are arranged in a ring at intervals on the outer circumferential wall of the water-blocking ring 423. The water-blocking ring 423 has the effect of blocking and collecting water, so that the rotating impeller 42 can rotate better.

[0053] To simplify the structure, the brush holder 44 and the rotating impeller 42 are integrated. The brush holder 44 includes symmetrically arranged mounting plates 441. One end of each mounting plate 441 is integrally connected to the rotating impeller 42, and the other ends are connected via connecting rings 442. The connecting rings 442 limit the movement of the brush holder 44 and the rotating impeller 42, ensuring they are centered and coaxial with the filter element assembly 3, thus guaranteeing effective cleaning. Specifically, there are two cleaning brushes 43 mounted on corresponding mounting plates 441. The bristles on the cleaning brushes 43 are arranged at an angle, with the bristle axis tangent to the outer circumferential wall of the filter element assembly 3, resulting in better cleaning.

[0054] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the filter element assembly 3 includes a filter element frame 31 and a composite filter element 32 inserted into the filter element frame 31. The filter element frame 31 has a hollow grid structure, and a filter screen 33 is installed on the outer circumferential wall of the filter element frame 31. The filter screen 33 is in contact with the cleaning brush 43. The upper end of the filter element frame 31 supports the rotating impeller 42, and the lower end of the filter element frame 31 is inserted into the base 2.

[0055] In some embodiments, such as Figure 3 , Figure 4 and Figure 8 As shown, the composite filter element 32 includes a filter element body 321 and a filter element upper cover 322 and a filter element lower cover 323 respectively fixed on the upper and lower sides of the filter element body 321. The filter element body 321 is a composite filter element (PP + carbon fiber). The filter element body 321, the filter element upper cover 322, and the filter element lower cover 323 are fixed together by adhesive. The filter element lower cover 323 is provided with a sealing lip 324 that matches the water outlet 201, and a third sealing ring 325 is installed on the filter element lower cover 323 to ensure the sealing of the connection.

[0056] In some embodiments, the housing 1 is made of a transparent material, allowing observation of the dirt and grime inside the housing 1, enabling timely rinsing or replacement of the filter element to ensure optimal performance.

[0057] In this specification, the same or similar parts between the various embodiments can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the descriptions of the embodiments described later are relatively simple, and relevant parts can be referred to the descriptions of the foregoing embodiments.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
