Water inlet hose 10 is connected to micro suction pump 9. The inlet of the suction pump 9 is fixedly connected, and the outlet hose 5 is fixedly connected to the outlet of the micro suction pump 9. Several limiting plates 12 are fixedly installed inside the outer shell 2 to provide support for the micro suction pump 9 and the mobile power supply 11, and to guide the inlet hose 10 through the opening. The outlet hose 5 extends out of the outer shell 2 and is fixedly connected to the second glass tube 21. A support frame 17 is fixedly installed on the side of the first limiting frame 13. The outlet hose 5 passes through the support frame 17, and the support frame 17 guides the outlet hose 5. The end of the inlet hose 10 is fixedly connected to the first glass tube 8, and the reagent to be extracted is placed below the first glass tube 8. The micro suction pump 9 is started. The micro suction pump 9 draws the reagent through the water inlet hose 10 and the first glass tube 8, and then pumps it into the extraction bottle placed in the limiting ring 14 through the water outlet hose 5 and the second glass tube 21. Baffles 7 are fixedly installed at both ends of the outer shell 2. Several ventilation grids 3 are opened on the outer shell 2.
