A spring 12 is provided on the outer wall, an L-plate 19 is slidably connected to the inner wall of the filter element fixing block 3, a pressure block 14 is fixedly installed on the outer wall of the L-plate 19, a limiting rod 15 and a fixing rod 17 are respectively fixedly installed on the inner wall of the filter element fixing block 3, a spring 2 16 is provided on the outer wall of the fixing rod 17, and a filter element main body 18 is slidably connected to the inner wall of the filter element fixing block 3. In the above structure, a square block is provided on the outer wall of the sample storage tank 8, and a square groove is provided on the inner wall of the box body 1. When installing the sample storage tank 8, the square block on the outer wall of the sample storage tank 8 is aligned with the square groove on the inner wall of the box body 1 and installed inwardly, so that the water outlet of the sample storage tank 8 will not be separated from the groove on the outer wall of the fixing shell 7.

[0024] In a preferred embodiment, there are two pull rods 13, and the two pull rods 13 are stacked and distributed on the inner wall of the box body 1. Two circular grooves are opened at the bottom of the sample storage tank 8, and the diameter of the circular groove is the same as the diameter of one end of the pull rod 13 close to the sample storage tank 8. In the above structure, the two pull rods 13 are inserted into the square grooves at the bottom of the sample storage tank 8, so that the two pull rods 13 fix the sample storage tank 8, thereby preventing the sample storage tank 8 from detaching from the interior of the box body 1.

[0025] In a preferred embodiment, the inner wall of the fixed shell 7 is adapted to the shape of the outer wall of the sample storage tank 8 on one side close to the fixed shell 7, and the sample storage tank 8 is fitted with the fixed shell 7. In the above structure, by placing the fixed shell 7 into the interior of the sample storage tank 8 and moving it upward, the water inlet at the top of the sample storage tank 8 enters the circular notch at the top of the fixed shell 7, so that the suction pump 6 can suck the liquid and discharge it into the interior of the sample storage tank 8 through the fixed shell 7.

[0026] In a preferred embodiment, the fixed shell 7 is connected to the detection device 9 through a water pipe, and a circular groove is provided on the outer wall of the fixed shell 7 near the water pipe, and a water-blocking ring is provided on the inner wall of the circular groove.

The two limit rods 15 limit the two sides of the L plate 19 so that the L plate 19 will not have different moving distances on both sides due to the change of the pressing center position.

[0028] In a preferred embodiment, a rectangular groove is provided on the outer wall of the main fixing block 2, and the size of the rectangular groove is adapted to the outer wall of the L-plate 19 close to the main fixing block 2. In the above structure, the L-plate 19 is inserted into the rectangular groove provided on the outer wall of the main fixing block 2, so that the L-plate 19 is fixed in the rectangular groove of the outer wall of the main fixing block 2, so that the filter element fixing block 3 is fixed.

[0029] Working principle: when in use, place the suction head 5 above the sample to be tested, start the suction pump 6 so that the suction pump 6 sucks the liquid through the hose 4. When the liquid passes through the filter element main body 18, most of the impurities in the liquid are adsorbed by the filter element main body 18. After the suction pump 6 sucks the liquid, it is discharged into the sample storage tank 8 through the fixed shell 7. The sample storage tank 8 stores the sample. At this time, start the detection device 9, the detection device 9 sucks the liquid and detects the liquid. The tested liquid is discharged from the drain port 10. When the detection is completed, pull out the pull handle 11, so that the pull handle 11 drives the pull rod 13 to move, so that the pull rod 13 is separated from the fixed shell 7, and then the spring 12 contracts. At this time, pull the sample storage tank 8 downward, so that the sample storage tank 8 is taken out from the inside of the fixed shell 7. At this time, the sample storage tank 8 is After cleaning the sample storage tank 8, pull out the pulling handle 11 to move the pull rod 13 and put the sample storage tank 8 back into the fixed shell 7. Release the pulling handle 11, and the spring 12 rebounds to push the pull rod 13 into the fixed shell 7 to fix the fixed shell 7. When the filter element main body 18 needs to be replaced, press the two pressing blocks 14 so that the two pressing blocks 14 drive the L plate 19 to move toward the inside of the filter element fixing block 3. When the two L plates 19 move to both sides of the outer wall extension piece of the limit rod 15, the two L plates 19 are separated from the main fixing block 2. At this time, pull the filter element fixing block 3 upward to take the filter element fixing block 3 out of the main fixing block 2, and then replace the filter element main body 18 in the inner wall of the filter element fixing block 3. After the replacement is completed, reset the filter element fixing block 3 to complete the replacement of the filter element main body 18.
