[0035] The filter membrane 4 is fixedly connected in the two insertion grooves 14 .

[0036] In a specific embodiment of the present utility model, the inner pipes of the lower prevention and control pipe 1 and the upper prevention and control pipe 2 are connected for conveying tap water, the upper prevention and control pipe 2 can slide in the lower prevention and control pipe 1, the insertion grooves 14 are respectively provided on the inner walls of the lower prevention and control pipe 1 and the upper prevention and control pipe 2, both sides of the filter membrane 4 are inserted in the insertion grooves 14, the filter membrane 4 is provided with tap water filtering micropores to filter some impurities in the tap water to achieve the effect of prevention and control, the filter membrane 4 is respectively connected to the lower prevention and control pipe 1 and the upper prevention and control pipe 2, when it is necessary to filter the tap water, the fixing component fixes the lower prevention and control pipe 1 and the upper prevention and control pipe 2, so that the upper prevention and control pipe 2 will not slide in the lower prevention and control pipe 1, and then the position of the filter membrane 4 is fixed, so that the filter membrane 4 can filter the impurities in the conveying pipeline. Impurities in the incoming water are filtered. When the filtration time is long and too many impurities are retained on the filter membrane 4 and affect the filtration efficiency, clean water can be introduced into the pipe, and the fixation between the lower prevention and control pipe 1 and the upper prevention and control pipe 2 can be released, so that the upper prevention and control pipe 2 can slide in the lower prevention and control pipe 1. The operator repeatedly moves the upper prevention and control pipe 2 externally, and the relative position change of the two insertion grooves 14 causes the filter membrane 4 and the micropores on the filter membrane 4 to repeatedly expand and contract. The impurities retained on the filter membrane 4 are separated from the filter membrane 4 during the repeated expansion and contraction, and are washed out of the pipe by the clean water, completing the cleaning of the filter membrane 4. When the device cleans the filter membrane 4, there is no need to open the pipeline, and the cleaning can be completed by only expanding and contracting the upper prevention and control pipe 2 to shake off the impurities on the filter membrane 4.

[0037] For details, please refer to Figure 1-Figure 4 A fixing component is provided in the lower prevention and control tube 1, and the fixing component includes a block groove 5, a fixed groove 6, a bead 7, an expansion groove 8, a spring groove 9 and a reset spring 10. There are multiple block grooves 5 and multiple bead 7. Multiple block grooves 5 are all opened on the circumferential inner wall of the lower prevention and control tube 1, and the fixed groove 6 is opened on the circumferential surface of the upper prevention and control tube 2. Multiple beads 7 are slidably connected in the block groove 5 and the fixed groove 6 respectively. The expansion groove 8 is opened on the circumferential inner wall of the movable sleeve 3, and the spring groove 9 is opened at the upper end of the lower prevention and control tube 1. The reset spring 10 is fixedly connected to the lower inner wall of the spring groove 9 and the lower end of the movable sleeve 3.

[0038] In this embodiment, the bead 7 can slide in the block slot 5, the fixed slot 6 and the expansion slot 8. In the normal state, the spring slot 9 abuts against the movable sleeve 3, so that the expansion slot 8 is arranged at the upper end of the bead 7 and is not connected with the block slot 5. The bead 7 is abutted by the inner wall of the movable sleeve 3 so that the bead 7 is stuck in the block slot 5 and the fixed slot 6. The fixed slot 6 is stuck by the bead 7 so that the upper prevention and control tube 2 cannot be pulled out of the lower prevention and control tube 1, and then the upper prevention and control tube 2 is fixed, so that the filter membrane 4 cannot be extended and retracted, and then the tap water is filtered. When the filter membrane 4 needs to be cleaned, the movable sleeve is pulled downward. Tube 3 is moved to contract the return spring 10, and the expansion groove 8 slides down to be connected with the card block groove 5. At this time, the upper prevention and control tube 2 is pulled, and the upper prevention and control tube 2 will push the card bead 7 into the expansion groove 8, and the card bead 7 will not fix the fixed card groove 6. At this time, the upper prevention and control tube 2 can slide freely, thereby driving the filter membrane 4 to expand and contract. When the cleaning is completed, the lower prevention and control tube 1 and the upper prevention and control tube 2 are closed and the movable sleeve 3 is released. The return spring 10 that was squeezed and contracted before rebounds, and the inclined surface on the lower side of the expansion groove 8 pushes the card bead 7 to be re-engaged in the fixed card groove 6 to complete the fixation of the upper prevention and control tube 2.
