Two connecting seats 21 are fixedly mounted on the limiting frame 20, a plurality of support rods 22 are fixedly mounted on each connecting seat 21, and the support rods 22 form a horn-shaped support cover around the water inlet pipe 11; the limiting frame 20 forms a frame with a sun-shaped cross-section, the water inlet pipe 11 and the water outlet pipe 12 extend through the limiting frame 20 to one side, the connecting seat 21 is annular, the end of the connecting seat 21 is fixedly connected with the side wall of the limiting frame 20, the other end face of the connecting seat 21 is equidistantly provided with a plurality of support rods 22 distributed in an annular array, the support rods 22 form arc-shaped rod bodies, the support rods 22 completely extend from the end face of the connecting seat 21, and the water inlet pipe 11 passes through the center position of the support cover; In this solution, by arranging the ports of the water inlet pipe 11 and the water outlet pipe 12 between the limiting frame 20 and the sealed housing 10, the ports of the water inlet pipe 11 and the water outlet pipe 12 are clamped and limited by the limiting frame 20 abutting against the side wall of the sealed housing 10, which can reduce the probability of dust, impurities and insects entering the sealed housing 10 from the ports of the water inlet pipe 11 or the water outlet pipe 12 during storage, has the effect of protecting internal components, and can ensure the cleanliness of the cleaned water inlet pipe 11 and water outlet pipe 12, facilitating next use. When the limiting frame 20 is far away from the sealed housing 10, a deformable support cover is formed by the plurality of support rods 22 at the end of the connecting seat 21, which can support the water inlet pipe 11 or the water outlet pipe 12, avoid sampling obstruction caused by right-angle bending of the water inlet pipe 11 or the water outlet pipe 12 during sampling, and ensure sampling stability.

[0020] As Figure 3 , Figure 4 and Figure 5 shown, the limiting structure is disposed between the sealed housing 10 and the limiting frame 20 and is used for limiting and fixing the position of the limiting frame 20; The limiting structure comprises a guide rod 23, a pull rod 24 and a sliding channel 25.
