The inner wall of the collecting barrel 5 is cleaned by rotating the cleaning component 7, and the sewage is discharged through the collecting component 9. There is no need to take out the collecting barrel 5 for cleaning, which reduces the threat to human health and is easy to use.

[0024] Combined with Figure 3 The rotating cleaning assembly 7 includes a motor 10 installed at the center of the bottom wall of the collecting barrel 5. The upper output end of the motor 10 is connected to a rotating shaft 11 that passes through the bottom wall of the collecting barrel 5. A plurality of sleeves 12 are sleeved and fixed on the rotating shaft 11. A pair of connecting rods 13 are symmetrically provided on the outer side of the sleeves 12. The ends of the pair of connecting rods 13 on the same side are fixed with scrapers 14 that contact the inner wall of the collecting barrel 5.

[0025] In combination with the above structure, when the rotary cleaning assembly 7 is used, the motor 10 drives the rotating shaft 11 to rotate, so that the sleeve 12 drives the connecting rod 13 to rotate, so that the scraper 14 rotates and scrapes off the chromatograph leakage attached to the inner wall of the collection barrel 5, thereby cleaning the collection barrel 5.
