The first vacuum pump 7 cooperates with the connecting channel 8 and the first one-way valve 9 to extract the air inside the sealed can 2, and then the air pressure inside the sealed can 2 can be reduced. Since the sample is extracted from the standard atmospheric pressure, the air pressure inside the sample is also consistent with the air pressure outside. Put it into the container 6. When the first vacuum pump 7 extracts the air inside the sealed can 2, the air pressure inside the sealed can 2 is reduced. The pressure inside the sample is lowered, and the pressure inside the sample is greater than the air pressure inside the sealed can 2, so that a pressure difference can be formed between the inside and outside of the sample, so that the water contained in the sample can automatically flow out and mix with the detection liquid, and then the knob 16 is manually turned, so that the movable plate 14 can be driven to rotate by the cooperation of the card slot 17 and the card column 18, and at the same time, the spiral limit groove 11 is adapted to the movable plate 14, so that the movable plate 14 can drive the sealing plug 15 to move upward after overcoming the elastic force of the first spring 19, so that the external air can flow into the sealed can 2 through the through hole 12 and the vent groove 13 to achieve pressure relief, so that the cover plate 4 can be opened without The electric power and driving device can be rotated by hand only, which is more reliable when used. After the cover plate 4 is opened, the high-speed adjustment of the mounting frame 21 can be achieved under the drive of the telescopic rod inside the base 20, so that the suction tube 27 can be inserted into the liquid of the container 6. The second vacuum pump 22 can extract the air inside the sample tube 23, so that the piston 24 moves upward, so that the sample can be directly drawn into the sample tube 23 through the connecting tube 25 and the suction tube 27. The sample can be prevented from flowing out through the second one-way valve 26. The sample can be collected and stored only through the sample tube 23. When collecting different samples, only the sample needs to be checked. By replacing the tube 23 and the suction tube 27, the sample can be prevented from being contaminated. A separate disposable collection tube is no longer needed, which is more economical. The movable groove 30, the connecting column 31 and the second spring 33 are adapted to enable the clamping plate 32 to move up and down, and then the sample tube 23 can be clamped by the clamping plate 32 that can be raised and lowered. At the same time, the sample tube 23 can be more convenient to load and take out. The air extraction hole at the top of the sample tube 23 can be connected to the second air extraction pump 22 through the connecting head 29 to make it better sealed and have a better effect when used.
