[0046] In one embodiment, as Figures 2 - 4As shown in the figure, the pushing component includes: a connecting push plate 2013 slidably connected inside the support frame 3. The outer wall of the connecting push plate 2013 is L-shaped. The outer wall of the connecting push plate 2013 is in contact with the outer wall of a limit baffle 203. One end of the connecting push plate 2013 is fixedly connected to a connecting slide rod 2012. The connecting slide rod 2012 penetrates to the outside of one end of the support frame 3.

[0049] The above embodiment discloses a water valve that is easy to clean. Among them, when in use, the sewage is discharged into the inner cavity of a water delivery tank through the water delivery pipe 5. At this time, the impurities in the sewage can be filtered by a filter screen cylinder 206, and then the filtered sewage is conveyed to the inner cavity of the valve body 1 to effectively avoid the situation that the impurities in the sewage cause wear to the valve body 1.

[0050] When a large amount of impurities accumulate in the inner cavity of a filter screen cylinder 206, at this time, through the placement opening 205, another filter screen cylinder 206 is inserted into the inner cavity of another water delivery tank. At this time, the limit ring 201 drives the limit baffle 203 to slide along the inner walls of the placement opening 205 and the water delivery tank until the limit ring 201 and the limit baffle 203 are in contact with the inner wall of one end of the switching cylinder 202, so as to facilitate the installation of another filter screen cylinder 206.

[0051] After that, manually rotate the gear 2014. At this time, the toothed ring 204 is driven by the meshing of the gear 2014 to drive the switching cylinder 202 to rotate along the inner wall of the support frame 3. At the same time, the limit baffle 203 is driven by the limit ring 201 to slide along the inner wall of the limit chute under the drive of the switching cylinder 202, so as to facilitate the switching of the two filter screen cylinders 206. During this process, the switching cylinder 202 effectively prevents the unfiltered sewage from being discharged into the inner cavity of the valve body 1.

[0052] During this process, the positioning block 209 moves synchronously under the drive of the switching cylinder 202. At this time, blocked by the inner wall of the positioning slot, the positioning block 209 pushes the connecting carriage 208 to slide along the inner wall of the switching cylinder 202. At the same time, the positioning block 209 contracts by moving and squeezing the first spring 207. Until the positioning block 209 moves to the end of the positioning slot, at this time, the first spring 207 pushes the positioning block 209 to insert into the interior of the positioning slot by rebounding, so as to rotate and position the switching cylinder 202;

[0053] After that, pull the connecting block 2010 away from the outer wall of the support frame 3. At this time, the connecting push plate 2013 slides along the inner wall of the support frame 3 under the drive of the connecting block 2010 through the connecting slide rod 2012, and squeezes the second spring 2011 to contract. At the same time, a limit baffle 203 drives the limit ring 201 to slide along the inner walls of the water delivery groove and the placement port 205 under the push of the connecting push plate 2013 until a limit baffle 203 moves to the outside of one end of the support frame 3, so as to facilitate the convenient disassembly of a filter cartridge 206, and thus the filtered impurities can be conveniently cleaned.

[0054] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
