The pressure plate 362 is arranged at the side of the flow limiting plate 33 and is also arranged in the range where the flow limiting plate 33 can deflect and collide, wherein the pressure plate 362 is slidably connected inside the flower-shaped plate 361, so that the pressure plate 362 drives the second filter screen 3653 fixed at the bottom of the pressure plate 362 to move rightwards, the second filter screen 3653 is connected with the first filter screen 3651 through the tension bar 3652, the tension bar 3652 is elastic, and the first filter screen 3651 is elastic, so that the filtering holes of the first filter screen 3651 are enlarged along with the rightward pulling of the tension bar 3652 on the first filter screen 3651, impurities in water flow can be circulated into a space surrounded by the first filter screen 3651 and the second filter screen 3653, the shape of the second filter screen 3653 is unchanged, and impurities in the water flow can be filtered and limited, and accordingly the impurities in the water flow are filtered.
The tensile length of the tension bar 3652 does not exceed the length of the second filter 3653 extending from the interior of the flower-shaped plate 361, and in addition, when water flow no longer enters the interior of the filter tube 31, all the moving components in the filter assembly 36 are restored to the original positions, and because the outlet plate 3603 and the moving components are magnetic, the moving components are repulsive to the outlet plate 3603, the second filter 3653 moves towards the first filter 3651 again, and the first filter 3651 is not pulled by the tension bar 3652, so that the holes of the first filter 3651 become smaller, and the impurities accumulated in the first filter 3651 and the second filter 3653 are prevented from running out again.
Wherein the force of water flowing into the inside of the filter tube 31 and striking the moving member is greater than the repulsive force of the discharge plate 3603 to the moving member, and the sampling device is not always immersed in water, so that the amount of corrosion of the magnetic material is negligible.

The former plays a role of blocking external impurities or dust when no water flows.
Because the tee 367 is also connected at one end to the center block 368, the center block 368 will move to the right along the center of the flower-shaped plate 361, wherein the pulling cone 369 fixed to the other end of the center block 368 will act to pull the water flow to the first filter 3651 and the second filter 3653, wherein the range of movement of the center block 368 to the right will not extend completely from the flower-shaped plate 361; when the water flow entering the filter tube 31 is excessive or the water flow entering the filter tube 31 is far greater than the water flow discharged from the first filter screen 3651 and the second filter screen 3653, the water flow is accumulated on the left side of the center block 368, the outside of the center block 368 is slidably connected with the drain plate 3601, and the drain plate 3601 is limited by the elastic strips 3602, wherein the connection part of the drain plate 3601 and the elastic strips 3602 has a filtering function, but when a large amount of water flow is accumulated, the elastic strips 3602 are stretched outwards, so that the water flow impacts the drain plate 3601 and moves rightwards, and the water flow accumulated on the left side of the center block 368 flows out from the notch 360 formed in the surface of the center block, so that the pressure of the accumulated water flow is relieved.
The above-mentioned drain plate 3601 originally blocks the opening 360, but the opening 360 is opened along with the high pressure impact of the water flow.
