[0029] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] See also Figures 1 to 7 As shown, the embodiment of the present application provides a water purification faucet, including:

[0031] The water inlet mechanism 1 is detachably connected to the faucet, and is provided with a switching mechanism 3 capable of directing tap water to the water purification mechanism 2;

[0032] A water purification mechanism 2 is connected to one side of the water inlet mechanism 1 and is provided with a filter element 20 for purifying tap water;

[0033] A self-cleaning mechanism 4 is movably disposed in the water purification mechanism 2 and is disposed around the filter element 20. The self-cleaning mechanism 4 can rotate along the center line of the filter element 20 to scrape and clean the filter element 20;

[0034] The start-stop mechanism 5 is movably arranged on the water purification mechanism 2 and is used for controlling the start or stop of the self-cleaning mechanism 4.

[0035] By providing a self-cleaning mechanism 4 and a start-stop mechanism 5 on the water purification mechanism 2, when the filter element 20 needs to be cleaned, the start-stop mechanism 5 is turned to start the self-cleaning mechanism 4. Then, driven by the water flow, the self-cleaning mechanism 4 can rotate along the center line of the filter element 20 to scrape and clean the circumference of the filter element 20, thereby removing debris and stains attached to the filter element 20, thereby realizing automatic cleaning of the filter element 20. There is no need to disassemble the filter element 20 separately, thereby greatly improving the cleaning efficiency, which is practical and convenient.

[0036] Furthermore, the self-cleaning mechanism 4 includes a cleaning frame 41 mounted on the filter element 20, a cleaning brush 42 disposed on the cleaning frame 41 and in contact with the peripheral side wall of the filter element 20, and a driving structure 43 capable of driving the cleaning frame 41 to rotate along the center line of the filter element 20 so that the cleaning brush 42 can scrape the peripheral side of the filter element 20.

[0037] Specifically, the driving structure 43 includes an impeller 431 rotatably arranged in the water purification mechanism 2, a plurality of paddle plates 432 arranged on the peripheral side wall of the lower end of the cleaning frame 41, and a plurality of driving rotating rods 433 arranged on the impeller 431 and capable of pressing against the corresponding paddle plates 432, wherein the impeller 431 rotates and drives the paddle plates 432 to rotate along with the driving rotating rods 433, thereby driving the cleaning frame 41 to rotate along the center line of the filter element 20 so that the cleaning brush 42 scrapes the peripheral side of the filter element 20.

[0038] In this embodiment, the working principle of the self-cleaning mechanism 4 is as follows: after the tap water flows out of the faucet and enters the water inlet mechanism 1, it is drained into the water purification mechanism 2 through the switching mechanism 3 and rushes to the impeller 431. The impeller 431 starts to rotate under the drive of the water flow, and drives the toggle plate 432 to rotate by driving the rotating rod 433, thereby driving the cleaning frame 41 to rotate along the center line of the filter element 20 so that the cleaning brush 42 can scrape the side wall of the filter element 20, remove the debris and stains attached to the filter element 20, and realize automatic cleaning of the filter element 20. There is no need to disassemble the filter element 20 separately, so the cleaning efficiency is greatly improved, which is practical and convenient.

[0039] Furthermore, the start-stop mechanism 5 includes a stop assembly 51 disposed in the water purification mechanism 2 and capable of limiting the rotation of the impeller 431 , and a lever assembly 52 capable of driving the stop assembly 51 to move closer to or away from the impeller 431 .

[0040] Specifically, the stop assembly 51 includes a stop rod 511 disposed in the water purification mechanism 2 and capable of engaging with the impeller 431 , a moving part 512 disposed at the lower end of the stop rod 511 and capable of engaging and connecting with the stop rod 511 , and an elastic part 513 disposed on the moving part 512 .

[0041] The lever assembly 52 includes a lever groove 521 opened on the side wall of the water purification mechanism 2, a lever 522 slidably arranged in the lever groove 521, and a start-stop structure 523 arranged in the water purification mechanism 2 and connected to the inner end of the lever 522.

[0042] In this embodiment, the working principle of the start-stop mechanism 5 is as follows:

[0043] When the filter element 20 needs to be cleaned, the lever 522 is pushed in the cleaning start direction (i.e., the start-stop structure 523 is moved toward the direction of the stop assembly 51), so that the start-stop structure 523 presses against one side of the movable member 512, and the movable member 512 is squeezed and rotated and the elastic member 513 is compressed synchronously. The elastic member 513 is compressed and releases the elastic force downward, thereby driving the movable member 512 and the stop rod 511 to move downward, and then releasing the impeller 431. The impeller 431 starts to rotate under the drive of the water flow, and drives the toggle plate 432 to rotate by driving the rotating rod 433, thereby driving the cleaning frame 41 to rotate along the center line of the filter element 20 to allow the cleaning brush 42 to scrape the peripheral side of the filter element 20, remove the debris and stains attached to the filter element 20, and realize automatic cleaning of the filter element 20 without the need to disassemble the filter element 20 separately, thereby greatly improving the cleaning efficiency and being practical and convenient.

[0044] When cleaning is completed and normal use is desired, the lever 522 is pushed in the direction of stopping cleaning (i.e., the start-stop structure 523 is moved away from the stop assembly 51), so that the start-stop structure 523 no longer presses against the movable part 512, and the elastic part 513 returns to its original state, thereby driving the movable part 512 and the stop rod 511 to move upward, and the stop rod 511 is extended under the impeller 431 to engage with it, thereby limiting the rotation of the impeller 431, and further stopping the self-cleaning mechanism 4, thereby achieving the effect of stopping cleaning, which is practical and convenient.

[0045] Furthermore, the water purification mechanism 2 includes a water purification shell 21 connected to one end of the water inlet mechanism 1, a water outlet seat 22 arranged at the lower end of the water purification shell 21, and a purified water discharge structure 23 and a sewage discharge structure 24 respectively arranged on the water outlet seat 22.

[0046] Specifically, the purified water discharge structure 23 includes a bubbler 231 disposed on the water outlet seat 22 , and a purified water outlet 232 opened on the water outlet seat 22 and connected to the bubbler 231 .

[0047] The sewage discharge structure 24 includes a sewage drainage cover 241 arranged at the lower end of the water outlet seat 22, a plurality of sewage discharge holes 242 opened at the lower end of the sewage drainage cover 241, and a sewage outflow port 243 opened on the water outlet seat 22 and connected to the sewage drainage cover 241. The sewage drainage cover 241 is also provided with a accommodating cavity 244 that can accommodate the bubbler 231.

[0048] In this embodiment, the start-stop structure 523 is also provided with a first outflow hole 71 and a second outflow hole 72 which can be connected to the clean water outlet 232 and the sewage outlet 243 respectively. When the filter element 20 is cleaned, the second outflow hole 72 is aligned and connected with the sewage outlet 243, while the clean water outlet 232 is staggered and blocked with the first outflow hole 71, so that the sewage in the cleaning process flows from the second outflow hole 72 and the sewage outlet 243 into the sewage drainage cover 241 and is discharged from the sewage discharge hole 242; when the water purifying faucet is purifying water normally, the first outflow hole 71 is aligned and connected with the clean water outlet 232, while the sewage outlet 243 and the second outflow hole 72 are staggered and blocked, so that the clean water flows from the first outflow hole 71 and the clean water outlet 232 into the bubbler 231 and is discharged from the water purifying mechanism 2, which is practical and convenient.

[0049] Furthermore, the water inlet mechanism 1 includes a water inlet outer shell 11 connected to the faucet, a water inlet inner shell 12 arranged in the water inlet outer shell 11, and a partition structure 13 arranged in the water inlet inner shell 12. The switching mechanism 3 is movably arranged in the partition structure 13. A water inlet chamber 14 and a water outlet chamber 15 are respectively formed in the water inlet inner shell 12 at the upper and lower ends of the partition structure 13. The lower end of the water inlet outer shell 11 is also provided with a water outlet hole 110 that can be connected to the water outlet chamber 15.

[0050] Specifically, a first connecting hole 131 and a second connecting hole 132 are also provided on the partition structure 13, wherein when the switching member 31 rotates to the drainage position, the switching member 31 connects the water inlet chamber 14 with the water purification mechanism 2 through the first connecting hole 131; when the switching member 31 rotates to the straight-out position, the switching member 31 connects the water inlet chamber 14 with the water outlet chamber 15 through the second connecting hole 132.

[0051] Furthermore, the switching mechanism 3 includes a switching member 31 rotatably disposed in the partition structure 13 , a switching rod 32 capable of driving the switching member 31 to rotate, and a switching handle 33 disposed outside the water inlet housing 11 and connected to the switching rod 32 .

[0052] The water inlet inner shell 12 is also provided with a water spraying member 6 which can extend into the water purification mechanism 2 .

[0053] In this embodiment, the working principle of the switching mechanism 3 is as follows: when it is necessary to divert the water flow into the water purification mechanism, rotate the switching handle 33 to drive the switching component 31 to rotate to the diversion position, so that the water inlet chamber 14 is connected with the water spray component 6, thereby allowing the water flow to flow from the water spray component 6 into the water purification mechanism 2; when it is not necessary to divert the water flow into the water purification mechanism, rotate the switching handle 33 in the opposite direction to drive the switching component 31 to rotate to the straight-out position, so that the water inlet chamber 14 is connected with the water outlet chamber 15, thereby allowing the water flow to flow out from the water outlet hole 110, which is practical and convenient.

[0054] In this embodiment, the working principle of the switching mechanism 3 is the prior art commonly used in the art and will not be described in detail here.

[0055] To sum up, in the embodiment of the present application, a self-cleaning mechanism 4 and a start-stop mechanism 5 are provided on the water purification mechanism 2. When the filter element 20 needs to be cleaned, the start-stop mechanism 5 is turned to start the self-cleaning mechanism 4. Then, the self-cleaning mechanism 4, driven by the water flow, can rotate along the center line of the filter element 20 to scrape and clean the circumference of the filter element 20, thereby removing debris and stains attached to the filter element 20, thereby realizing automatic cleaning of the filter element 20. There is no need to disassemble the filter element 20 separately, thereby greatly improving the cleaning efficiency, and being practical and convenient.
