DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may conceive of other obvious variations. Example

[0027] See also Figure 1-6The utility model provides a split filter, comprising a filter housing 1, two fixing rings 2 fixed to the inner cavity of the filter housing 1, a center plate 4 fixed at the middle position of the fixing ring 2, a filter layer 3 fixed between the center plate 4 and the inner circumference of the fixing ring 2, and an anti-blocking mechanism for cleaning and discharging impurities;

[0028] The anti-clogging mechanism includes a scraping component and a discharge component;

[0029] When the filter housing 1 is in use, the filter layers 3 located at the inner circumferences of different fixing rings 2 can filter impurity particles of different sizes, so that impurities of different sizes can be filtered out step by step. During long-term use, a large amount of impurities will adhere to the surface of the filter layer 3. The scraping component can clean the impurities attached to the surface of the filter layer 3 and separate them from the filter layer 3, and the cleaned impurities can be discharged to the outside of the filter housing 1 through the discharge component, so that the user can clean the impurities attached to the surface of the filter layer 3, thereby avoiding the occurrence of clogging of the surface of the filter layer 3 due to a large amount of impurities attached.

[0030] See also Figure 1-6 The scraping assembly includes an inner bin 9 opened at the middle position of the inner cavity of the center plate 4, a rotating shaft 10 that penetrates and rotates connected to the middle position of the center plate 4, two scraping strips 11 fixed on both sides of the outer circumference of the rotating shaft 10, a sealing component acting on the surface of the rotating shaft 10, a movable shaft 5 rotatably connected to the top of the center plate 4, a third bevel gear 12 fixedly sleeved on the outer circumference of the movable shaft 5 and the outer circumference of the rotating shaft 10 at the inner cavity position of the inner bin 9, and a driving component acting on the movable shaft 5. The top of the movable shaft 5 passes through the adjacent center plate 4, the fixing ring 2 and the filter housing 1 and extends to the position at the top of the filter housing 1. The two adjacent third bevel gears 12 are meshed and connected;

[0031] Under the action of the driving component, the two movable shafts 5 can be rotated, so that the third bevel gears 12 at adjacent positions can be rotated under the meshing action between the two third bevel gears 12, so that the third bevel gear 12 can drive the two scraping strips 11 on its outer circumference to rotate, so that the friction force between the scraping strips 11 and the filter layers 3 at adjacent positions can scrape off impurities attached to the surfaces of both sides of the filter layer 3, and the sealing component can prevent moisture from directly seeping from one side of the fixing ring 2 at the inner bin 9 to the other side of the fixing ring 2, thereby ensuring that the water passing through the fixing ring 2 can be fully filtered by the filter layer 3.

[0032] See also Figure 1-6The driving component includes a motor 6 fixed to the top of the outer peripheral surface of the filter housing 1, a rotating rod 23 rotatably connected to the surface of the filter housing 1 at the top position of the motor 6, a first bevel gear 7 fixedly sleeved on the movable shaft 5 and extending out of the filter housing 1 at the output end of the motor 6, and a plurality of second bevel gears 8 fixedly sleeved on the outer peripheral surface of the rotating rod 23, and the first bevel gear 7 is meshedly connected with the second bevel gear 8 at the adjacent position;

[0033] By starting the motor 6, one of the first bevel gears 7 is rotated, so that the rotating rod 23 can be rotated under the meshing action between the first bevel gear 7 and the second bevel gear 8 at the adjacent position, so that the two movable shafts 5 can be rotated synchronously under the meshing action between the other two first bevel gears 7 and the second bevel gear 8.

[0034] See also Figure 1-6 The sealing component includes a sealing ring groove 13 formed in the inner cavity of the center plate 4 and located on both sides of the inner chamber 9, and a sealing ring disk 14 fixedly sleeved on the outer circumference of the rotating shaft 10 and located inside the sealing ring groove 13. The outer circumference of the sealing ring disk 14 is in contact with the inner circumference of the sealing ring groove 13.

[0035] When the rotating shaft 10 rotates, the sealing ring disc 14 can be driven to rotate in the inner cavity of the sealing ring groove 13 at the adjacent position, thereby not affecting the rotation of the rotating shaft 10. In addition, due to the connection between the sealing ring disc 14 and the inner wall of the sealing ring groove 13, a sealing effect can be achieved from both sides of the inner cavity of the inner chamber 9, thereby preventing moisture from directly seeping from one side of the fixing ring 2 in the inner chamber 9 to the other side of the fixing ring 2, thereby ensuring that the water passing through the fixing ring 2 can be fully filtered by the filter layer 3. Example

[0036] Reference Figure 1-6 As shown, the discharge assembly includes a connecting pipe 15 fixedly connected to the bottom of the filter housing 1 and located on both sides of the adjacent fixing ring 2, a discharge pipe 16 fixedly connected to one side of the outer peripheral surface of the connecting pipe 15, a first one-way valve 21 installed at the top of the inner cavity of the connecting pipe 15, a second one-way valve 22 installed on one side of the inner cavity of the discharge pipe 16, a piston disc 20 slidably inserted in the middle position of the inner cavity of the connecting pipe 15, and a movable rod 19 fixed to the bottom of the piston disc 20, which passes through the connecting pipe 15 and extends out of the bottom of the connecting pipe 15;

[0037] When it is necessary to discharge the impurities scraped from the surface of the filter layer 3 to the outside of the filter housing 1, after a certain amount of water is transported to the inner cavity of the filter housing 1, the movable rod 19 can slide in the inner cavity of the connecting pipe 15, so that the air pressure in the inner cavity of the connecting pipe 15 can change. Due to the setting of the first one-way valve 21, the piston disc 20 can slide vertically downward in the inner cavity of the connecting pipe 15. After the air pressure in the inner cavity of the connecting pipe 15 changes, the first one-way valve 21 is opened, so that the water mixed with impurities flows into the interior of the connecting pipe 15, and the piston disc 20 is opened. When the inner cavity of the connecting pipe 15 stops sliding and slides vertically upward, the interior of the first one-way valve 21 is closed, and under the setting action of the second one-way valve 22, when the piston disk 20 slides vertically upward in the inner cavity of the connecting pipe 15, the air pressure in the inner cavity of the connecting pipe 15 changes again, which can open the second one-way valve 22 so that the moisture entering the inner cavity of the connecting pipe 15 and the moisture mixed with impurities can be discharged from the discharge pipe 16 under the change of air pressure, and when the piston disk 20 stops sliding and slides vertically downward in the inner cavity of the connecting pipe 15, the interior of the second one-way valve 22 is closed.

[0038] Reference Figure 1-6 As shown, the discharge assembly further includes a pull plate 18 fixed at the bottom of the two movable rods 19 and a spring telescopic rod 17 fixed at the middle of the two adjacent connecting tubes 15, one end of the spring telescopic rod 17 is fixed to the surface of the pull plate 18 at the adjacent position;

[0039] By pulling the pull plate 18, the two movable rods 19 can be synchronously driven to slide in the inner cavity of the connecting tube 15, so that raising the pull plate 18 can facilitate the synchronous vertical downward movement of the two adjacent movable rods 19, thereby causing the spring telescopic rod 17 to deform, so that the pull plate 18 can automatically move vertically upward under the action of the rebound force of the spring telescopic rod 17, thereby facilitating the user to make the piston disc 20 slide back and forth in the inner cavity of the connecting tube 15.
