Description

Technical Field

[0001] The utility model relates to a full-automatic sample injector, belonging to the technical field of sample injecting devices. Background Art

[0002] The fully automatic sampling device generally includes a sample tube, a special sampling needle, a shifting mechanism, etc. The shifting mechanism is used to move the sampling needle to the top of the sample tube and drive the sampling needle to move up and down so that the sampling needle can be inserted into the sample tube. The software of the detector controls the automatic sampling and testing of the sample. With the improvement of the management level of the testing laboratory, more and more attention is paid to the health protection of the testing personnel. Many laboratories place the testing equipment, automatic sampler and control computer in two different rooms or keep a long distance from the computer to minimize the direct contact between the testing personnel and the reagents or samples. In this case, it is more troublesome to use the traditional wired control method.

[0003] There are still some problems in the use of existing fully automatic samplers. The sampling needle is not positioned correctly and is inserted crookedly. At the same time, the sample cannot be automatically moved to the sampling position during sampling, resulting in low work efficiency and unsafe conditions. Utility Model Content
