The filtering mechanism 7 comprises a filtering channel 71 located between the water supply tank 4 and the water storage tank 6, a foreign matter treatment barrel 72 communicated with the filtering channel 71, a filtering plate 73 for filtering foreign matters, a first baffle 74 arranged between the filtering channel 71 and the water supply tank 4, and a second baffle 76 arranged between the filtering channel 71 and the foreign matter treatment barrel 72. The second baffle 76 blocks the filtering channel 71 and the foreign matter treatment barrel 72, so as to ensure that the water flow in the water storage tank 6 fully flows into the water supply tank 4. The foreign matter treatment barrel 72 is horizontally arranged at the bottom of the tower body 1 and below the water storage tank 6 and the water supply tank 4.

[0040] One end of the filtering channel 71 is fixedly connected with the water outlet of the water storage tank 6 through welding, the other end of the filtering channel 71 is fixedly connected with the water inlet of the water supply tank 4 through welding, the water inlet of the foreign matter treatment barrel 72 is fixedly connected with the filtering channel 71 through welding, and the filtering channel 71 is communicated with the foreign matter treatment barrel 72. The filtering plate 73 is arranged between the filtering channel 71 and the water storage tank 6. When the filtering plate 73 is rotated to the vertical direction, the filtering plate 73 separates the water storage tank 6 and the filtering channel 71. The first baffle 74 is arranged between the filtering channel 71 and the water supply tank 4. When the first baffle 74 is rotated to the vertical direction, the first baffle 74 separates the water supply tank 4 and the filtering channel 71. The second baffle 76 is arranged between the filtering channel 71 and the foreign matter treatment barrel 72. When the second baffle 76 is rotated to the horizontal direction, the second baffle 76 separates the foreign matter treatment barrel 72 and the filtering channel 71.

[0041] The filter channel 71 is provided with a guide plate 711 between the filter channel 71 and the impurity treatment barrel 72, and the guide plate 711 is arranged obliquely downward. One side of the guide plate 711 is fixedly connected with the filter channel 71 by welding, and the other side of the guide plate 711 is fixedly connected with the water inlet of the impurity treatment barrel 72 by welding. By arranging the guide plate 711 between the filter channel 71 and the impurity treatment barrel 72, the guide plate 711 has a certain guiding effect on the water flow, so as to ensure that the impurities on the filter plate 73 are smoothly flowed into the impurity treatment barrel 72 under the driving of the water flow.

[0042] With reference to Figure 5 , the bottom of the water storage tank 6 is provided with a guide surface 61, and the guide surface 61 is arranged obliquely downward from a position away from the filter channel 71 to a position close to the filter channel 71. The guide surface 61 has a certain guiding effect on the movement direction of the impurities in the water storage tank 6, so that the impurities in the water storage tank 6 enter the impurity treatment barrel 72 under the driving of the water flow, and the filtering effect of the filtering mechanism 7 is ensured.

[0043] With reference to Figure 6 , Figure 7 and Figure 8 , the filtering mechanism 7 further comprises a rotating assembly 75 for driving the filter plate 73 and the baffle to rotate, and the rotating assembly 75 comprises a first rotating rod 751 for driving the filter plate 73 to rotate and a third rotating rod 753 for driving the second baffle 76 to rotate. One end of the first rotating rod 751 is fixedly connected with the side wall of the filter plate 73 by welding, and the other end of the first rotating rod 751 is located outside the filter channel 71. A first rotating hole is formed in the filter channel 71 close to the water storage tank 6, and the first rotating rod 751 is sealingly and rotatably connected with the inner side wall of the filter channel 71 through the first rotating hole. One end of the third rotating rod 753 is fixedly connected with the side wall of the second baffle 76 by welding, and the other end of the third rotating rod 753 is located outside the filter channel 71. A third rotating hole is formed in the filter channel 71 close to the impurity treatment barrel 72, and the third rotating rod 753 is sealingly and rotatably connected with the inner side wall of the filter channel 71 through the third rotating hole. By arranging the first rotating rod 751 in the rotating assembly 75, the rotation of the filter plate 73 is realized under the premise of ensuring the sealing of the filter channel 71; by arranging the third rotating rod 753, the rotation of the second baffle 76 is realized under the premise of ensuring the sealing of the filter channel 71.

The first sealing ring 771 is fixedly connected to the sidewall of the filtering plate 73 by adhesion, and the first sealing ring 771 gradually thins from the position close to the filtering plate 73 to the position away from the filtering plate 73. The second sealing ring 772 is fixedly connected to the sidewall of the first baffle 74 by adhesion, and the second sealing ring 772 gradually thins from the position close to the first baffle 74 to the position away from the first baffle 74.

[0045] Since the side of the first sealing ring 771 away from the filtering plate 73 is thinner than the side close to the filtering plate 73, the side of the first sealing ring 771 in contact with the inner wall of the filtering channel 71 has better elastic deformation ability. Similarly, the side of the second sealing ring 772 in contact with the inner wall of the filtering channel 71 has better elastic deformation ability. When the filtering plate 73 rotates in the vertical direction, the shape of the first sealing ring 771 allows the first sealing ring 771 to smoothly contact the filtering channel 71 to achieve sealing. When the first baffle 74 rotates in the vertical direction, the shape of the second sealing ring 772 allows the second sealing ring 772 to smoothly contact the filtering channel 71 to achieve sealing.

[0046] Through the arrangement of the sealing assembly 77, when the water storage tank 6 and the water supply tank 4 are connected, the first sealing ring 771 ensures that the impurity-containing water flow does not flow into the water supply tank 4 through the gap between the filtering plate 73 and the filtering channel 71, so that the water flow passing through the filtering plate 73 is fully filtered. When the water storage tank 6 and the water supply tank 4 are blocked by the second baffle 76, the second sealing ring ensures that the impurity-containing water flow does not flow into the water supply tank 4 through the gap between the second baffle 76 and the filtering channel 71, so that the impurities on the filtering plate 73 fully flow into the impurity treatment barrel 72.

By arranging the second rotating rod 752, the rotation of the first baffle 74 is realized under the premise of ensuring the sealing of the filtering channel 71.

[0049] The power assembly 78 further comprises a second driving motor 782 for driving the second rotating rod 752 to rotate, and the output shaft of the second driving motor 782 is fixedly connected with the end of the second rotating rod 752 away from the filtering plate 73 by welding, so that the rotation of the second rotating rod 752 can be realized by operating the second driving motor 782 by the staff.

[0051] The filtering channel 71 of the filtering mechanism 7 is located between the water storage tank 6 and the water supply tank 4, and is used for connecting the water storage tank 6 and the water supply tank 4, so that when the water in the water storage tank 6 circulates into the water supply tank 4, the impurities are blocked on one side of the filtering plate 73. The second driving motor 782 drives the second rotating rod 752 to rotate, the second rotating rod 752 drives the first baffle 74 to rotate to the vertical direction, the first baffle 74 blocks the connection between the filtering channel 71 and the water supply tank 4; at the same time, the third rotating rod 753 drives the second baffle 76 to rotate, and the second baffle 76 is rotated to the vertical direction; the first driving motor 781 drives the first rotating rod 751 to rotate, the first rotating rod 751 drives the filtering plate 73 to overturn, the impurities blocked on one side of the filtering plate 73 are brought into the filtering channel 71 by the water flow, and the impurities on the filtering plate 73 flow into the impurity treatment barrel 72 under the action of the water flow.
