Abstract

The invention relates to a liquid sampling device, which comprises a rocker arm 1, a needle fixing base 2, a return spring 3, a guide rod 4, an ultrasonic vibrator 5, a vibrator mounting sleeve 6 and a sampling needle 7, wherein the needle fixing base 2 is fixed with the rocker arm 1 by passing through the rocker arm 1; the needle fixing base 2 is provided with first and second through holes; the second through hole comprises upper and lower through holes which are coaxial; the diameter of the lower through hole is more than the diameter of the upper through hole; the sampling needle 7 is connected to the needle fixing base 2 by passing through the first through hole; the ultrasonic vibrator 5 is placed inside the vibrator mounting sleeve 6; the vibrator mounting sleeve 6 is fixedly connected to the sampling needle 7; one end of the guide rod 4 is connected to the mounting sleeve 6 while the other end of the guide rod 4 is inserted into the lower through hole and contacts with one end of the return spring 3 in the lower through hole; the diameter of the return spring 3 is more than the diameter of the upper through hole; the guide rod 4 is a hollow barrel with upper and lower parts opened; the power line of the ultrasonic vibrator 5 is extended out of a channel formed by the guide rod 4, the return spring 3 and the upper through hole; and the upper end of the sampling needle 7 is connected to an injection pump. The liquid sampling device has a stirring function, is convenient to portable and operate, and has small cleaning work load.

Description

technical field [0001] The invention relates to the field of sample sampling, in particular to a liquid sampling device. Background technique [0002] In the process of scientific and technological research and development, it is usually necessary to sample and stir samples and reagents. At present, an independent sampling device is usually used to sample the samples and reagents, and another independent stirring device is used to stir the sampled samples and reagents to ensure the uniformity of the solution and the accuracy of the test results. [0003] In practice, it is found that the sampling device and the stirring device are independent of each other, which is inconvenient to carry and operate; in addition, after the sampling and stirring are completed, the value-taking device and the stirring device must be cleaned separately, and the cleaning workload is heavy. Contents of the invention [0004] The invention provides a liquid sampling device with a stirring funct...
