TECHNICAL FIELD

[0001] The utility model relates to sampling technical field, specifically point to a kind of cosmetic inspection extraction device. BACKGROUND

[0002] Cosmetics are various in type, and different types of cosmetics have different textures, some have good fluidity, and some have poor fluidity, i.e., different viscosity.

[0003] For cosmetics with low viscosity, a conventional extraction sampler can be directly used for sampling. For cosmetics with high viscosity, it is difficult to extract and sample, and backflow is easy to occur. Therefore, a digging method is used, i.e., a medicine spoon or a small spoon is used to dig the sample.

[0004] The cosmetic inspection extraction device provided by the present application integrates the digging structure and the extraction structure through structural design, so that the sampling means of the sampling device can select a sampling mode according to the texture of the cosmetics.
