[0002] A pre-filter is the first coarse filter for water in a house, filtering out silt, rust, and large particles from the tap water. It's typically installed after the water meter on the inlet pipe to prevent any harmful precipitation from the pipe network. It also protects concealed pipes, faucets, and electrical appliances.

[0003] Most pre-filters on the market have the following disadvantages when used:

[0004] First, although the flushing flow rate of the pre-filter is large, for large particles of dirt, simply flushing the filter surface with water flow cannot remove some stubborn dirt attached to the filter, which indirectly reduces the filtering effect of the filter.

[0050] For example: In some embodiments, the filter bottle 13 can be made of martensitic stainless steel. It should be emphasized that martensitic stainless steel has good load-bearing capacity and antioxidant capacity. These characteristics make the service life of the device significantly longer than that of devices made of other metals in actual use.

[0051] like Figure 1 As shown, in the embodiment provided in the present application, a detachable water divider 8 is installed on the top of the inner skeleton 10, wherein a plurality of oblique spoiler blades 803 are provided on the circumference of the water divider 8, the top end of the outer end of the inner skeleton 10 is slidably connected to the impeller 9, and a detachable switching part 7 is installed inside the inner skeleton 10.

[0052] It should be emphasized that the bottom end of the switching member 7 is rotatably screwed with a piston 15 , the piston 15 is arranged at the bottom end inside the inner frame 10 , and the top of the switching member 7 is clamped with the backwash frame 5 .

[0058] It should be further explained that in the embodiment provided in the present application, a sealing ring 6 is installed in the gap between the inner skeleton 10, the valve head 4 and the backwash skeleton 5. A spraying part 19 is rotatably connected to the skeleton of the inner skeleton 10. The spraying part 19 is a cylindrical structure. The inner wall of the cylinder and the outer wall of the skeleton are rotatably connected. A plurality of water spray holes are opened on the outside of the spraying part 19.

[0059] It should be noted that in the embodiment provided in the present application, a stainless steel filter screen 11 is installed on the outside of the backwash skeleton 5, and the two ends of the stainless steel filter screen 11 are fixed to the two ends inside the filter bottle 13. The bottom of the outside of the spraying part 19 is fixedly connected with a cleaning flap. There are multiple cleaning flaps, which are evenly distributed at equal distances on the outside of the spraying part 19. The spraying part 19 is in contact with the stainless steel filter screen 11 through the cleaning flap.

[0060] like Figure 5 As shown, in the embodiment provided in the present application, the bottom end of the backwash frame 5 is fixedly connected with a convex rib, the switching member 7 includes an assembly seat 702, the top end of the assembly seat 702 is fixedly connected with a concave rib 701, and the switching member 7 is connected to the backwash frame 5 through the concave rib 701 and the convex rib;

[0061] A groove 703 is formed at the bottom end of the assembly seat 702 , and the sealing ring 6 is installed on the assembly seat 702 through the groove 703 .

[0062] It should also be noted that in the embodiment provided in the present application, a spraying member 19 is rotatably connected to the switching member 7, and the spraying member 19 is a cylindrical structure. The inner wall of the cylinder and the outer wall of the frame are rotatably connected, and the spraying member 19 is provided with two rows of multiple staggered oblique water spray holes 1901, and a plurality of oblique blades 1902 are also provided on the outside of the upper end of the spraying member 19.

[0063] like Figure 3 As shown, in the embodiment provided in the present application, a groove 703 is provided at the bottom end of the assembly seat 702 , and the assembly seat 702 is used to install the sealing ring 6 through the groove 703 .

[0064] like Figure 5As shown, in the embodiment provided in the present application, siphon holes 1501 are respectively opened at both ends of the piston 15, and a silicone pad 16 is installed between the piston 15 and the inner wall of the outer frame 12;

[0065] It should be noted that a washer 20 is fixed to one end of the inner frame 10, the upper end of the washer 20 contacts and supports the spraying member 19, a backwash spring 14 is installed between the washer 20 and the bottom end of the inner frame 10, and a snap-fit ​​groove 1001 and a positioning groove 1002 are opened on the outer portion of the upper end of the inner frame 10;

[0066] The inner ring outside the water divider 8 is provided with a snap buckle 801 and a positioning rib 802 . The water divider 8 is fixed to the inner frame 10 through the snap groove 1001 and the snap buckle 801 , and is positioned through the positioning groove 1002 and the positioning rib 802 .

[0067] like Figure 7 As shown, in the embodiment provided in the present application, when the device is in the filtering state, the water pressure at various locations inside the filter bottle 13 is basically the same. At this time, the elastic force of the backwash spring 14 acts on the plane of the gasket 20 and the inner skeleton 10 to support the gasket 20. Since the gasket 20 moves synchronously with the switching member 7 and the piston 15, it is supported by the backwash spring 14 together. It should be emphasized that the groove 703 is used to install the O-ring, which is used to seal the gap between the switching member 7 and the inner skeleton 10 to prevent water from flowing through the gap between the two. It also has different functions in actual use.

[0068] When the device is in the filtering stage, it can prevent unfiltered water from directly entering the water purification area without being filtered by the stainless steel filter 11, thereby improving the filtering effect.

[0069] When the device is in the flushing stage, it can prevent water from flowing through the gap between the two, reduce the backwash water pressure and affect the backwash effect.

[0070] In addition, when the device is actually filtering, a vortex is formed after the water flows through the blades on the impeller 9, generating centrifugal force to separate impurities so that the impurities will not stick to the filter screen or filter bottle, thereby enhancing the backwash effect. At the same time, when the water flow hits the side of the oblique spoiler, the water flow will drive the impeller 9 to rotate.

[0071] like Figure 6As shown, when the device is in the sewage discharge state, the sewage discharge ball valve 17 is manually opened to flush and discharge. After the sewage discharge ball valve 17 is opened, water flows out of the two siphon holes 1501 on the piston 15, and the piston 15 moves downward under the action of water pressure. Because the internal thread on the piston 15 is screwed with the external thread on the switching member 7, the switching member 7, the piston 15 and the gasket 20 are connected, so that the piston 15 drives the switching member 7 and the gasket 20 to move downward together until the 702 surface on the switching member 7 contacts the outside of the inner skeleton 10, the switching member 7, the gasket 20 and the piston 15 stop moving downward. At this time, the sealing ring 6 installed on the switching member 7 is also driven downward together. The water flows from the gap between the sealing ring 6 and the main cavity 2 to the inside of the backwash skeleton 5, and then passes through the inside of the switching member 7, and the spraying member 19 sprays water outward to flush the stainless steel filter screen 11.

[0072] It should be noted that, at this time, the spray holes on the spray member 19 direct the water flow into the side walls of the spray holes when discharging water, thereby causing the spray member 19 to rotate, thereby achieving simple flushing of the stainless steel filter screen 11.

[0073] It should also be noted that, in the embodiment provided in the present application, the main cavity 2 and the water inlet and outlet connecting pipes 3 are both made of non-metallic environmentally friendly materials.

[0074] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
