Embodiment Construction

[0032] Such as Figure 1 to Figure 5 As shown, in view of existing defects, the subject of protection of this patent is as follows:

[0033] The sampler housing 1 is made of plastic, metal or glass. The sampler housing 1 is a cylindrical housing with two interfaces at the front end and an open opening at the rear end, and is provided with a convenient finger hook. The retaining hand 11 that lives, the retaining hand extends up and down two directions. And a screw thread is arranged at the position close to the opening.

[0034] Adjustment cylinder 2, the adjustment cylinder includes a cylindrical part 21 and a hexagonal operating part 22, wherein a thread 23 is provided on the outer surface of the cylindrical part, and cooperates with the threaded part on the sampler housing to form a threaded connection, through the hexagonal The operating part 22 can be operated to adjust the screw-in length of the cartridge in the sampler housing.

[0035] The inner column 3 of the sampl...

Abstract

The invention discloses a liquid sample sampling device and method used for detection of a quick-detection sample and provides an all-in-one machine. The liquid sample sampling device comprises a sampling device shell, an adjusting barrel, a sampling device inner column and one-way check valves, wherein the adjusting barrel is mounted at an opening end of the sampling device shell through thread connection; the middle part of the sampling device inner column penetrates through the adjusting barrel and can slide along the axial direction; a spring is fixedly connected between the sampling device inner column and the adjusting barrel; one connector in two connectors of the sampling device shell is connected with a tee joint; residual two pipe openings of the tee joint are connected with a first one-way check valve and a ball valve respectively; and the second connector on the sampling device shell is connected with a second one-way check valve. According to the liquid sample sampling device and method, disclosed by the invention, previous three sampling devices, a standard solution container and a detection liquid sampling device are integrated into an organic whole body, so that the utilization efficiency is improved, sampling, mixing and detection can be finished by the device in one step, and the sampling detection efficiency is improved.

Description

technical field [0001] The invention relates to a sampling and testing tool, in particular to a liquid sample sampling device for quick sample testing. Background technique [0002] At present, in the detection process, the sample is first sampled with a sampler, for example: "Take 100 ml of the original sample, and then add the sample taken into a standard solution device, which has a pre-prepared standard solution, the sample solution is mixed with the standard solution, and then the mixed solution is sampled for cultivation and analysis”, [0003] In this process, three steps need to be completed, one is to have a quantitative sampler to extract the original sample, the other is to have the preparation solution of the standard solution device to carry out the miscibility of the sample, and the third is to carry out the miscible liquid Quantitative sampling for rapid detection. [0004] In the process of these three steps, three instruments and equipment are needed, one ...
