Description

Technical Field

[0001] The utility model belongs to the technical field of sample extraction, and in particular relates to a nail polish sample extraction device. Background Art

[0002] In the production process of nail polish, it is necessary to extract samples of the nail polish in the production process to ensure the quality of the nail polish product. However, in the manual sampling process, nail polish is volatile, nail polish products are easy to catch fire, and nail polish has certain toxicity. The safety of the manual sampling process is not high. Among them, the "A sampling device for methyl methacrylate samples" disclosed in the application number "CN202020426371.7" is also an increasingly mature technology. By providing a sealed box and a vacuum pump, when sampling methyl methacrylate samples, methyl methacrylate is placed in a sealed box. At the same time, the inside of the sealed box is evacuated by a vacuum pump to reduce the probability of methyl methacrylate contacting the air during sampling, thereby improving the safety of the sampling device. However, the device also has the following defects: the equipment cannot directly extract samples in production, there are certain limitations when used on site, and the sample extraction amount cannot be accurately controlled. During use, it cannot adapt to different sample test tubes, it is not convenient to install and disassemble the sample test tubes, and the test tubes are sealed after the samples are extracted from the sample test tubes, which is easy to cause sample leakage.
