[0041] like Figure 1 As shown, this embodiment provides an automatic cleaning and filtering device, including: a flushing water path 1, which is connected to the water tank 31 of the toilet 3 and supplies water to the toilet bowl 32 of the toilet 3; the flushing water path 1 is equipped with a filter device 100; and a cleaning water path 2, which includes a valve body 300, the valve body 300 having a water outlet for cleaning the filter device 100, the water outlet being connected to or facing the filter device 100. It can be understood that the water in the water tank 31 is filtered by the filter device 100 and then guided by the flushing water path 1 to other components of the toilet 3, such as the pump and the switching valve 200. The filter device 100 removes dirt or sand particles from the water source, preventing wear on the toilet 3 components and improving the service life of the equipment. In this embodiment, a cleaning water path 2 is provided. By controlling the opening and closing of the valve 300 on the cleaning water path 2, cleaning water or cleaning liquid is allowed to flow through the outlet of the cleaning water path 2 to flush the filter device 100, dispersing and discharging the dirt or sand particles accumulated on the filter device 100, keeping the filter device 100 unobstructed, and ensuring the water flow and flushing effect from the flushing water path 1 to the brush ring channel 210 and the main flushing channel 220. The process of cleaning the filter device 100 is simple and quick, reducing equipment maintenance costs and greatly improving the user experience.

[0042] In some embodiments, such as Figures 2-5 As shown, the filtration device 100 includes a filter screen 110 arranged intersecting the water flow direction, and the filter screen 110 can be one or more layers. In this embodiment, the filtration function of the filtration device 100 is mainly achieved through the filter screen 110. In some other embodiments, the filter screen 110 can also be replaced by other structures with filtration functions such as filter cartridges and filter columns. Specifically, the main body 120 of the filtration device is a cuboid cage structure. The filter screen 110 includes a first layer of filter screen 111 and a second layer of filter screen 112. The first layer of filter screen 111 and the second layer of filter screen 112 are respectively arranged on the inner and outer sides of the side wall of the main body 120 of the filtration device. After the water flows through the first layer of filter screen 111 and the second layer of filter screen 112, it enters the main body 120 of the filtration device and flows into the flushing water channel 1 from the outlet 121 provided at the top of the main body 120 of the filtration device.

[0043] In some embodiments, such as Figures 2-5 As shown, the cleaning water path 2 also includes a filter screen cleaning device 400, which is connected to the outlet end of the valve body 300. The filter screen cleaning device 400 includes at least a first-layer filter screen cleaning channel 420, which has at least one spray nozzle 410 facing the filter screen 110. In this embodiment, the filter screen cleaning device 400 and the spray nozzle 410 are used to divert and adjust the rinsing position of the cleaning water or cleaning liquid in the cleaning water path 2, so that the cleaning water path 2 can rinse the filter device 100 more thoroughly and comprehensively.

[0044] In some embodiments, such as Figures 2-5 As shown, the filter cleaning device 400 includes a first-layer filter cleaning channel 420 and a second-layer filter cleaning channel 430; the spray nozzle 410 includes a first spray nozzle 421 and a second spray nozzle 431. The first-layer filter cleaning channel 420 is provided with multiple first spray nozzles 421, and the second-layer filter cleaning channel 430 is provided with multiple second spray nozzles 431. In this embodiment, the cleaning water path 2 is split through the first-layer filter cleaning channel 420 and the second-layer filter cleaning channel 430. A portion of the cleaning water or cleaning liquid flows through the first-layer filter cleaning channel 420 and flows out from the first spray nozzle 421 to rinse the first-layer filter 111. At the same time, another portion of the cleaning water or cleaning liquid flows through the second-layer filter cleaning channel 430 and flows out from the second spray nozzle 431 to rinse the second-layer filter 112. It should be noted that the number of filter cleaning channels and spray nozzles can be set as needed and is not limited here.

[0045] In some embodiments, such as Figures 2-5 As shown, the first-layer filter cleaning channel 420 and the second-layer filter cleaning channel 430 are configured in series or in parallel. It is understandable that the series-connected first-layer filter cleaning channel 420 and second-layer filter cleaning channel 430 have a simpler structure, and the cleaning channel closer to the water inlet has a greater water impact force and higher rinsing intensity, making it more effective for rinsing areas prone to dirt accumulation. The parallel-connected first-layer filter cleaning channel 420 and second-layer filter cleaning channel 430 ensure uniform water output from each cleaning channel, avoiding rinsing dead zones due to insufficient water pressure.

[0046] In some embodiments, such as Figures 2-5As shown, the filter cleaning device 400 is mounted on the upper side of the filter device 100. The filter cleaning device 400 is a tubular U-shaped frame 440, which includes two straight sides 441 and a curved portion 442 connecting the two straight sides 441. The spray nozzle 410 is located on the two straight sides 441 and faces the filter screen 110. In this embodiment, the filter device body 120 is a cuboid cage structure. The first side wall of the cage structure forms a first layer of filter screen 111, and the second side wall opposite to the first side wall forms a second layer of filter screen 112. The first layer of filter screen 111 and the second layer of filter screen 112 are respectively located on the inner and outer sides of the side wall of the filter device body 120. The filter device body 120 is provided with a top plate 122, and the top plate 122 is provided with an outlet 121 communicating with the flushing water channel 1. The U-shaped frame 440 of the filter cleaning device 400 is mounted on the top plate 122. Specifically, a mounting plate is provided in the middle of the U-shaped frame 440, and the mounting plate is detachably locked to the top plate 122 by bolts. A connector 443 is provided on one straight side 441 of the U-shaped frame 440 to connect to the outlet of the valve body 300 of the cleaning water circuit 2. Specifically, the outlet is led out through a first connecting pipe 301 and connected to the connector 443. The two straight edges 441 of the U-shaped frame 440 are respectively arranged along the two long sides of the filter device body 120. The two straight edges 441 are respectively mounted on the upper side of the first layer filter screen 111 and the second layer filter screen 112. The two straight edges 441 are respectively provided with a first spray port 421 on the outside of the filter device body and a second spray port 431 on the inside of the filter device body. The first spray port 421 and the second spray port 431 are respectively facing the first layer filter screen 111 and the second layer filter screen 112 and the spray ports are tilted downward, so that the filter screen 110 can be washed from top to bottom during rinsing.

[0047] In some embodiments, such as Figure 1 and Figure 6 As shown, valve body 300 is a water inlet valve 310, which has a first water outlet channel 311 for supplying water to the water tank 31 of the cleaning water path 2 and / or the toilet 3; and / or, the water inlet valve 310 has a second water outlet channel 312 for supplying water to the water seal of the cleaning water path 2 and / or the toilet 3. In this embodiment, both the first water outlet channel 311 and the second water outlet channel 312 are provided. Water entering the water inlet valve 310 first flows to the first water outlet channel 311 and the second water outlet channel 312, and then flows from the second water outlet channel 312 to the filter cleaning channel of the filter cleaning device 400 for cleaning the filter screen, and finally flows into the water tank 31.

[0048] In some embodiments, such as Figure 1 and Figure 6As shown, the flushing water path 1 also includes a pumping device 500, which is used to draw water from the water tank 31 of the toilet 3 to the toilet bowl 32 of the toilet 3. A filter device 100 is provided at the front end of the pumping device 500, which is located outside the water tank 31; or the filter device 100 is located inside the water tank 31. In this embodiment, the filter device 100 is provided at the front end of the pumping device 500, and the rear end is connected to a switching valve 200 provided in the flushing water path 1. Specifically, the pumping device 500 draws filtered water from the water tank 31 from the outlet 121 at the top of the filter device body 120 through a second connecting pipe 501, and then the pumping device 500 pumps the filtered water into the flushing water path 1 for flushing the toilet bowl 32 of the toilet 3.

[0049] In some embodiments, such as Figure 1 and Figure 6 As shown, the flushing water path 1 also includes a switching valve 200, which is connected to the pumping device 500 and used to switch the water supply between the brush ring channel 210 and the main flush channel 220 of the toilet 3.

[0050] like Figures 1 to 7 As shown, in some embodiments, a toilet is also provided, including an automatic cleaning and filtering device as described in any of the above embodiments. In this embodiment, during installation, the filter device 100 and valve body 300 (i.e., the inlet valve 310) of the automatic cleaning and filtering device are located in the water tank 31 of the toilet 3. Water entering the inlet valve 310 flows into the water tank 31 via the first outlet channel 311 and into the filter screen cleaning device 400 via the first connecting pipe 301 of the second outlet channel 312 to rinse the filter device 100. After rinsing, the rinsing water is dispersed in the water tank 31. The filtered water entering the filter device 100 is pumped by the pumping device 500 through the second connecting pipe 501 to the switching valve 200 for flushing the brush ring channel 210 and the main flush channel 220 of the toilet 3.
