Problems solved by technology

[0002] In the sampling process of liquid samples, manual sampling is commonly used at present. This method is complicated to operate, and there is a risk of direct contact between the operator and the sample. It has high requirements for the quality of the operator, and there are certain safety hazards.
On the other hand, during the sampling process, affected by various factors such as human operation time, sample source pressure, and vacuum degree in the sampling bottle, the sampling volume of the sample is extremely unstable.
In the case where the sample is a high-level liquid or requires a small and precise sampling volume, the manual sampling method is not competent

Abstract

The invention discloses an automatic sampling device used for a liquid sample. The automatic sampling device is characterized in that: a shell is provided with a handle, a sampling nozzle and a sampling bottle, the shell is provided with an air exhaustion channel and a sampling channel therein; the sampling bottle is provided with a sampling opening and an air control opening, an air exhaustion opening of the air exhaustion channel is in sealed communication with the air control opening; and the sampling channel communicates with the sampling nozzle and the sampling opening. The automatic sampling device of the invention has the beneficial effects that: hidden dangers of manual sampling in the prior art can be solved, the shell is provided with the sampling nozzle and the sampling bottle,and is equipped with the air exhaustion channel and the sampling channel, thus operation is simple and convenient, direct contact between an operator and a sample can be avoided during sampling, and asampling volume can be controlled accurately.

Description

technical field [0001] The invention relates to a sampling device, in particular to an automatic sampling device for liquid samples. Background technique [0002] In the sampling process of liquid samples, manual sampling is commonly used at present. This method is complicated to operate, and there is a risk of direct contact between the operator and the sample. It has high requirements for the quality of the operator, and there are certain safety hazards. . On the other hand, during the sampling process, affected by various factors such as human operation time, sample source pressure, and vacuum degree in the sampling bottle, the sampling volume of the sample is extremely unstable. In the occasions where the sample is a high-level liquid or requires a small and precise sampling volume, the manual sampling method is not competent. Therefore, it is very necessary to design an automatic sampling device with simple structure, safe and convenient use, stable sampling volume an...
