[0027] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1 to 5 As shown in the figure, this application embodiment provides a water purifier faucet with automatic filter cleaning, characterized in that it includes:

[0029] The water purification housing 1 has a water inlet 10 at one end;

[0030] Filter element 2 is disposed inside the water purification housing 1;

[0031] The cleaning rack 3 is movably disposed inside the water purification housing 1 and surrounds the filter element 2. It is provided with a plurality of cleaning brushes 30 that can scrape and wash the side walls of the filter element 2.

[0032] The impeller 4 is rotatably disposed inside the water purification housing 1 and is connected to the cleaning frame 3. Water flows into the water purification housing 1 from the water inlet 10 and drives the impeller 4 to rotate, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape and wash the peripheral side wall of the filter element 2.

[0033] By cooperating with the cleaning frame 3 and the drive impeller 4, when water flows into the water purification housing 1 from the inlet 10, it drives the drive impeller 4 to rotate, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape and wash the side wall of the filter element 2, removing the debris and stains attached to the filter element 2, realizing automatic cleaning of the filter element 2 without having to disassemble the filter element 2 separately, greatly improving cleaning efficiency and making it practical and convenient.

[0034] Furthermore, a plurality of actuating plates 31 are arranged around the lower end of the cleaning frame 3, and a plurality of driving rods 40 are provided on the driving impeller 4 that can press against the corresponding actuating plates 31. The driving impeller 4 rotates and drives the actuating plates 31 to rotate through the driving rods 40, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape the peripheral sidewall of the filter element 2.

[0035] In this embodiment, the working principle of filter element 2 cleaning is as follows: water flows into the water purification housing 1 from the water inlet 10 and rushes towards the drive impeller 4. Driven by the water flow, the drive impeller 4 starts to rotate, and through the drive rod 40, it drives the actuating plate 31 to rotate, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape the side wall of the filter element 2, removing the debris and stains attached to the filter element 2, realizing automatic cleaning of the filter element 2. There is no need to disassemble the filter element 2 separately, greatly improving the cleaning efficiency and making it practical and convenient.

[0036] Furthermore, the water purification housing 1 is also provided with a stop structure 5 that can restrict the rotation of the drive impeller 4, and a lever structure 6 that can drive the stop structure 5 to move closer to or further away from the drive impeller 4.

[0037] Specifically, the stop structure 5 includes a stop rod 51 disposed inside the water purification housing 1 and capable of engaging with the drive impeller 4, a movable member 52 disposed at the lower end of the stop rod 51 and capable of engaging with the stop rod 51, and an elastic member 53 disposed on the movable member 52.

[0038] The lever structure 6 includes a lever groove 61 formed on the side wall of the water purification housing 1, a lever 62 slidably disposed in the lever groove 61, and an opening and closing assembly 63 disposed in the water purification housing 1 and connected to the inner end of the lever 62.

[0039] In this embodiment, when the filter element 2 needs to be cleaned, the lever 62 is moved in the cleaning start direction (i.e., the start / stop component 63 moves closer to the stop structure 5), so that the start / stop component 63 presses against one side of the moving part 52. The moving part 52 is squeezed and rotates, and simultaneously compresses the elastic part 53. The elastic part 53 is compressed and releases elastic force downward, thereby driving the moving part 52 and the stop rod 51 to move downward, thereby releasing the drive impeller 4. The drive impeller 4 starts to rotate under the drive of the water flow, and drives the lever 40 to drive the actuating plate 31 to rotate, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape the periphery of the filter element 2, removing the debris and stains attached to the filter element 2, realizing the automatic cleaning of the filter element 2 without having to disassemble the filter element 2 separately, greatly improving the cleaning efficiency and making it practical and convenient.

[0040] When cleaning is complete and normal use is complete, move lever 62 in the direction of stopping cleaning (i.e., move start / stop component 63 away from stop structure 5), so that start / stop component 63 no longer presses against moving part 52, elastic part 53 returns to its original state, thereby driving moving part 52 and stop rod 51 to move upward, and causing stop rod 51 to extend into the underside of drive impeller 4 and engage with it, restricting the rotation of drive impeller 4, thereby stopping the rotation of cleaning frame 3, achieving the effect of stopping cleaning, which is practical and convenient.

[0041] Specifically, the water purification housing 1 includes a water inlet housing 11, and an upper protective housing 12 and a lower protective housing 13 respectively connected to the upper and lower ends of the water inlet housing 11.

[0042] Furthermore, a water outlet seat 14 is provided between the water inlet shell 11 and the lower protective shell 13, and a clean water discharge structure 7 and a sewage discharge structure 8 are respectively provided on the water outlet seat 14.

[0043] Specifically, the purified water discharge structure 7 includes an aerator 71 disposed on the water outlet seat 14 and a purified water outlet 72 disposed on the water outlet seat 14 and connected to the aerator 71.

[0044] The sewage discharge structure 8 includes a sewage drain cover 81 located at the lower end of the water outlet seat 14, a plurality of sewage discharge holes 82 opened at the lower end of the sewage drain cover 81, and a sewage outlet 83 opened on the water outlet seat 14 and connected to the sewage drain cover 81.

[0045] The sewage drain cover 81 is also provided with a receiving cavity 84 that can accommodate the aerator 71.

[0046] In this embodiment, the start / stop component 63 is also provided with a first outlet hole 91 and a second outlet hole 92 that can be connected to the clean water outlet 72 and the sewage outlet 83 respectively. When the filter element 2 is cleaned, the second outlet hole 92 is aligned with the sewage outlet 83 and connected, while the clean water outlet 72 is offset from the first outlet hole 91 and blocked, so that the sewage during the cleaning process flows from the second outlet hole 92 and the sewage outlet 83 into the sewage drain cover 81 and is discharged from the sewage discharge hole 82; when the water purifier is purifying water normally, the first outlet hole 91 is aligned with the clean water outlet 72 and connected, while the sewage outlet 83 and the second outlet hole 92 are offset from the second outlet hole 92 and blocked, so that the clean water flows from the first outlet hole 91 and the clean water outlet 72 into the aerator 71 and is discharged out of the lower protective shell (13), which is practical and convenient.

[0047] In summary, the embodiments of this application, through the cooperative arrangement of the cleaning frame 3 and the drive impeller 4, when water flows into the water purification housing 1 from the inlet 10, drives the drive impeller 4 to rotate, thereby driving the cleaning frame 3 to rotate along the center line of the filter element 2 so that the cleaning brush 30 can scrape and wash the side walls of the filter element 2, removing the debris and stains attached to the filter element 2, realizing automatic cleaning of the filter element 2 without the need to disassemble the filter element 2 separately, greatly improving cleaning efficiency, and being practical and convenient.
