when the staff needs to clean the screw thread collecting bottle 423, the staff only needs to rotate the screw thread collecting bottle 423 downwards, the contact area of the screw thread collecting bottle 423 and the adjusting plate 432 continuously moves downwards in the process of moving the screw thread collecting bottle 423 downwards, the resistance to the adjusting plate 432 is reduced, the resistance to the second spring 437 is reduced along with the resistance, the second spring 437 pushes back the blocking sealing plate 431 fast through the fourth mounting groove 436, when the discharging frame 421 and the screw thread collecting bottle 423 are completely separated, the blocking sealing plate 431 just blocks the discharging frame 421 to seal the discharging frame 421, and the staff can clean solid impurities normally until the screw thread collecting bottle 423 and the external screw thread pipe 422 are completely separated, so that the staff is not required to pause the whole quantitative pumping system and clean the whole quantitative pumping system, and the whole working efficiency of the quantitative pumping system is guaranteed.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
