[0034] By rotating the second bolt 10 and separating it from the mounting plate 11, when the second bolt 10 no longer squeezes the moving block 25, the rebound force of the spring three 24 and the second telescopic rod 23 drives the clamping block 22 to move, separate from the clamping slot 20, and slide into the slide slot 26, so that it can filter impurities or harmful substances through the filter plate 21 and disassemble the filter plate 21; by rotating the turntable 4, the regulating plate 12 is driven to rotate through the valve stem 3 to adjust the water flow rate. When the valve stem 3 is broken, the valve stem 3 is rotated and adjusted through the fixing ring 2.

[0035] Reference Figure 1 and Figure 3The right side of the valve body 1 is fixedly connected with a mounting pipe 5, the interior of the mounting pipe 5 is slidably connected with a connecting pipe 6, the outside of the mounting pipe 5 is fixedly connected with a fixing tube 8, the upper side of the interior of the fixing tube 8 is threadedly connected with a first bolt 7, the outside of the first bolt 7 is provided with a spring 13, one side of the first bolt 7 is externally threadedly connected with a moving plate 14, and the corresponding side of the moving plate 14 is provided with a fixing fastener 15 on the left and right, one end of the spring 13 is fixedly connected to one side of the inner wall of the fixing tube 8, the other end of the spring 13 is fixedly connected to one side of the moving plate 14, the corresponding side of the fixing fastener 15 is fixedly connected with a first telescopic rod 16, the corresponding side of the first telescopic rod 16 is fixedly connected with a fixing block 17, one side of the fixing block 17 is fixedly connected to the corresponding side of the moving plate 14, the outside of the first telescopic rod 16 is provided with a spring 2 18, one end of the spring 2 18 is fixedly connected to one side of the fixing block 17, and the other end of the spring 2 18 is fixedly connected to the corresponding side of the fixing fastener 15.

[0036] The first bolt 7 is rotated to drive the movable plate 14 to move, and the spring 13 is pulled. At the same time, the first telescopic rod 16 is driven by the fixing block 17 to move the fixing fastener 15. When the fixing fastener 15 moves out of the through groove 19, the first telescopic rod 16 and the spring 2 18 lose their extrusion, and the generated rebound force drives the fixing fastener 15 to move and buckle the connecting pipe 6, so that it can be installed on the installation pipe 5 and the connecting pipe 6.

[0037] Reference Figure 3-Figure 5 Through grooves 19 are provided around the inside of the installation pipe 5 and the connecting pipe 6, and the movable plate 14 and the fixing fastener 15 are slidably connected inside the through groove 19; the filter plate 21 is slidably connected inside the filter tube 9; a slide groove 26 is provided inside the installation plate 11, and the block 22 is slidably connected inside the slide groove 26; the corresponding side of the inside of the filter tube 9 is provided with evenly distributed card grooves 20, and the card block 22 is slidably connected inside the card groove 20.

[0038] By moving the movable plate 14 and the fixing fastener 15 in the slide groove 26, the fixing fastener 15 is removed to install the connecting pipe 6; the liquid flowing in the filter tube 9 is filtered by the filter plate 21; and the clamping block 22 is moved in the slide groove 26, so that the mounting plate 11 can be installed and disassembled.

[0039] Working principle: when the device needs to be used, the first bolt 7 is rotated to drive the movable plate 14 to move, and the fixed fastener 15 is driven to move through the fixed block 17. When the fixed fastener 15 moves out of the through slot 19, the first telescopic rod 16 and the rebound force of the second spring 18 make the fixed fastener 15 move and fit the connecting pipe 6 to buckle it, thereby realizing the installation of the installation pipe 5 and the connecting pipe 6, which is fast and convenient and improves the installation efficiency. When the liquid enters the filter tube 9, the impurities or harmful substances inside it are filtered through the filter plate 21, and the second bolt 10 is rotated and moved out to separate it from the mounting plate 11. The second bolt 10 no longer squeezes the movable block 25, so that the rebound force of the spring three 24 and the second telescopic rod 23 drives the block 22 to move, separate from the card slot 20 and move to the inside of the slide slot 26, thereby realizing the filtration of the liquid, preventing impurities or harmful substances from damaging the regulating valve, and disassembling and cleaning the filter assembly to prevent impurities from blocking the filter screen and affecting the filtration.
