It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0020] See also Figure 1 , Figure 2 , Figure 3 This is a schematic diagram of the structure of the patent, a filterable water supply and drainage pipeline, including a water supply and drainage pipeline 1 and a filter cartridge 2, there are two water supply and drainage pipelines 1, a filter cartridge 2 is installed between the two water supply and drainage pipelines 1 through a flange, and the filter cartridge 2 is connected to the two water supply and drainage pipelines 1;

[0021] After entering the filter cartridge 2, the water in the water supply and drainage pipeline 1 will be filtered through the filter cotton block 6 inside it, filtering out impurities in the water flow, thereby avoiding excessive impurities in the water that affect domestic water use;

[0022] The water filtered by the filter cartridge 2 can be used for washing, washing vegetables, flushing toilets, etc.;

[0023] The inner wall of the filter cartridge 2 is installed with a partition 3, which divides the filter cartridge 2 into an upper chamber 4 and a lower chamber 5. Filter cotton blocks 6 are inserted and installed inside the upper chamber 4 and the lower chamber 5. The two filter cotton blocks 6 are respectively attached to the inner walls of the upper chamber 4 and the lower chamber 5.

[0024] The filter cartridge 2 is divided into two chambers by the partition plate 3, and is used in conjunction with the ball valve 12, so that in normal use, both chambers are in an open state, and the water flow is filtered through the filter cotton blocks 6 in the two chambers. When the filter cotton blocks 6 need to be replaced, the upper chamber 4 and the lower chamber 5 can be closed in turn through the ball valve 12, so that the filter cotton blocks 6 in the closed chambers can be replaced without affecting water use;

[0025] Through holes 7 are provided on both the upper and lower sides of the filter cartridge 2. The two through holes 7 are connected to the upper chamber 4 and the lower chamber 5 respectively. Covers 8 are rotatably installed on the outer sides of the two through holes 7.

[0026] When the filter cotton block 6 needs to be replaced, the corresponding ball valve 12 needs to be closed first, and then the sealing cover 8 is screwed down, and then the filter cotton block 6 can be pulled out through the connecting rope 10 for replacement, which is very convenient to operate.

[0027] The side walls of the two filter cotton blocks 6 are both inserted with one end of the fixing rod 9, the other end of the fixing rod 9 is installed with a connecting rope 10, and the side wall of the end of the fixing rod 9 inserted into the filter cotton block 6 is installed with an insertion rod 11, and the insertion rod 11 is inserted into the filter cotton block 6;

[0028] The filter cotton block 6 can be fixed by the insertion rod 11 to prevent the filter cotton block 6 from being separated from the fixing rod 9.

[0029] Ball valves 12 and fixed cylinders 13 are installed on the upper and lower sides of the partition 3. The two ball valves 12 respectively block the upper chamber 4 and the lower chamber 5. The two fixed cylinders 13 are respectively inserted into the upper chamber 4 and the lower chamber 5. The filter cotton block 6 is located between the ball valve 12 and the fixed cylinder 13, and the filter cotton block 6 is in contact with the side wall of the fixed cylinder 13.

[0030] The ball valve 12 includes a valve body 121, a ball 122, a water flow channel 123, a threaded hole 124 and an adjusting screw 125. The valve body 121 is installed on the side wall of the partition 3. The valve body 121 fits the inner wall of the filter cartridge 2. The ball 122 is rotatably installed inside the valve body 121. The side wall of the ball 122 is provided with a water flow channel 123. The upper wall of the valve body 121 penetrates the side wall of the filter cartridge 2 and is provided with a threaded hole 124. The adjusting screw 125 is screwed into the threaded hole 124 and connected to the upper wall of the ball 122.

[0031] When the adjusting screw 125 is rotated to connect the water flow channel 123 in the ball 122 with the through groove of the valve body 121, the ball valve 12 is in an open state, and water can enter the chamber corresponding to the ball valve 12 and be filtered by the filter cotton block 6 in the chamber;

[0032] In this article, the connection between the ball valve 12 and the filter cartridge 2 is provided with a sealing gasket and other structures to ensure that there will be no water leakage at the connection between the two. The connection between the water supply and drainage pipeline 1 and the filter cartridge 2 is also provided with a sealing gasket to avoid water leakage.

[0033] A fixing ring 14 is installed in the inner cavity of the fixing cylinder 13, a baffle 15 is rotatably installed on the side wall of the fixing ring 14, one end of a spring 16 is installed on the side wall of the baffle 15, and the other end of the spring 16 is installed on the inner side wall of the fixing ring 14;

[0034] By providing the baffle 15 , the fixing ring 14 and the spring 16 , the fixing cylinder 13 forms a simple one-way valve to prevent the filtered water from flowing back into the filter cylinder 2 .

[0035] The inner wall of the fixed cylinder 13 is provided with a retaining net 17, and the filter cotton block 6 is fitted with the side wall of the retaining net 17;

[0036] The blocking net 17 can block the filter cotton block 6 to prevent the filter cotton block 6 from being washed into the fixed cylinder 13 by the water flow.

[0037] When the patent is working, it is necessary to ensure that the two ball valves 12 are in the open state. At this time, the water flow in the water supply and drainage pipeline 1 is filtered by the filter cotton block 6 in the two chambers, and then discharged. The filter cotton block 6 filters out the impurities in the water flow, thereby avoiding excessive impurities in the water and affecting domestic water use;

[0038] When the filter cotton block 6 needs to be replaced, the upper chamber 4 and the lower chamber 5 can be closed in turn through the ball valve 12, and then the cover 8 can be unscrewed, and the filter cotton block 6 can be pulled out and replaced through the connecting rope 10, so that the filter cotton block 6 in the closed chamber can be replaced without affecting the water use.
