In some embodiments, the water inlet is arranged at the top of the filter chamber, and the sewage outlet is arranged at the lower end of the filter chamber.

[0036] The guide tube 4 is located inside the filter chamber, one end of the guide tube 4 is fixedly connected to the shell 1 and communicated with the water inlet; the sealing cover 5 is detachably connected to the sewage outlet, and a sewage outlet pipe 6 is fixedly arranged on the sealing cover 5; the filter cartridge 7 is fixedly connected to the filter chamber through the guide tube 4 and the sealing cover 5, and the sewage in the water inlet pipe 2 enters the filter cartridge 7 after passing through the water inlet through the filter cartridge 7, and the filtered water enters the filter chamber through the 2 holes of the filter net 7, although the water pressure in the filter chamber increases, the filtered water is discharged into the drain pipe.

[0037] The connecting surface between the water inlet pipe 2 and the shell 1 and the connecting surface between the shell 1 and the guide pipe 4 are both inclined surfaces, and the water inlet pipe 2, the shell 1 and the guide pipe 4 are arranged perpendicular to each other, so that the water inlet pipe 2, the shell 1, the guide pipe 4 and the water outlet pipe 3 are connected to facilitate the sewage to enter the filter cartridge 7 and the filtered water to enter the filter chamber.

[0038] In some implementations, the water inlet pipe 2, the housing 1, the flow guide pipe 4 and the water outlet pipe 3 are integrally arranged.

[0039] A plurality of circumferentially distributed positioning rods 8 are fixedly provided on the side wall of the flow guide tube 4. A positioning groove 9 is provided on the side of the positioning rod 8 opposite to the filter cartridge 7 for inserting the end of the filter cartridge 7 into the flow guide tube 4. In some implementations, the inner diameter of the filter cartridge 7 is larger than the outer diameter of the flow guide tube 4. Through the positioning rods 8 and the positioning grooves 9, after the positioning cartridge is inserted into the filter cavity, it is convenient to position the filter cartridge 7 so that the filter cartridge 7 is located in the middle of the filter cavity and is arranged along the axial length direction of the filter cavity.

[0040] A plurality of circumferentially distributed positioning plates 10 are fixedly provided on one side of the guide tube 4 opposite to the filter cartridge 7. The outer walls of the positioning plates 10 are adapted to the outer wall of the filter cartridge 7. In some implementations, the outer diameter formed by the plurality of positioning plates 10 cooperating with each other is smaller than the inner diameter of the filter cartridge 7. The positioning plates 10 are used to facilitate supporting and limiting the positioning cartridge.

[0041] The filter cartridge 7 comprises a filter frame 71 , a filter screen 72 is fixedly provided on the outer side of the filter frame 71 , a chuck 73 is fixedly provided on one end of the filter frame 71 away from the flow guide tube 4 , and a flow guide tube 74 is fixedly provided on the chuck 73 .

[0042] The sealing cover 5 is threadedly connected to the shell body 1, and a clamping ring 11 is fixedly provided on the side of the sealing cover 5 opposite to the chuck 73, which is used to insert the chuck 73 into the inside of the clamping ring 11. Through the sealing cover 5, after the filter cartridge 7 is installed in the filter chamber, the filter cartridge 7 can be fixed in the filter chamber, and after fixation, the chuck 73 is located inside the clamping ring 11, which further increases the stability and sealing of the filter cartridge 7 in the filter chamber.

[0043] The outer wall of the sealing cover 5 is also provided with anti-skid patterns, which facilitate the staff to perform forward / reverse rotation of the sealing cover 5 .

[0044] The working principle of this embodiment is as follows: sewage enters the guide pipe 4 through the water inlet pipe 2, and the sewage in the guide pipe 4 directly enters the filter cartridge 7. At this time, the water in the filter cartridge 7 is discharged into the filter cavity through the mesh on the filter screen 72. As the amount of water in the filter cavity increases, the filtered water will be discharged from the housing 1 through the water outlet pipe 3.

[0045] When the filter cartridge 7 needs to be cleaned, the water inlet pipe 2 is closed to allow the cleaning water to enter the filter chamber through the water outlet pipe 3. At the same time, the sewage pipe 6 is opened. When the cleaning water is discharged from the sewage pipe 6, the impurities attached to the inner wall of the filter cartridge 7 can be brought out of the filter cartridge 7, so that the filter cartridge 7 can be backflushed to complete the cleaning of the filter cartridge 7.

[0046] Example 2

[0047] See also Figure 5-7 , and also includes a limiting component 12 arranged in the filter cavity, which is used to limit the movement direction of the filter frame 71. The limiting component 12 is arranged between two adjacent positioning rods 8. Through the limiting component 12, the staff can limit the filter cartridge 7 when installing it, so as to avoid the filter cartridge 7 not being well installed in the preset position due to the limited installation environment, resulting in the sealing cover 5 not being able to completely seal the filter cavity, and also causing the filter cartridge 7 to be unable to filter the sewage well.

[0048] In some embodiments, two limit assemblies 12 are provided, and the two limit assemblies 12 are symmetrically distributed inside the filter cavity with respect to the axis of the filter cavity. The limit assemblies 12 include a first pad 121 fixedly provided on the inner wall of the filter cavity, a guide rail 122 fixedly provided on the first pad 121, a second pad 123 fixedly provided on the filter frame 71, and a slider 124 fixedly provided on the second pad 123.
