In the production and manufacturing process of cosmetics, it is necessary to strictly control the microbial content inside the cosmetics, and the microbial content inside the cosmetics must be detected and analyzed. During the detection and analysis, the microorganisms need to be extracted and filtered. Therefore, a filter device for cosmetics detection is needed. However, the current filter device for cosmetics detection still has the following shortcomings:

[0003] For example, the patent document with application number 202021490907.8 discloses a filtering device for cosmetic microbial detection. The filtering device for cosmetic microbial detection can filter larger impurities in the cosmetic solution by setting a filter net to prevent the larger impurities from affecting the extraction of microorganisms, thereby ensuring the accuracy of microbial measurement data. However, it is inconvenient to remove the extracted microorganisms, and the interior is difficult to clean. Impurities can easily mix into the solution after long-term use, resulting in the detection results being affected.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4 A movable liquid collecting box 4 is arranged inside the lower end of the filter box 1, and a liquid leakage hole 5 is provided on the lower surface of the filter box 1, an observation window 7 is arranged on the front surface of the filter box 1, and a fixing frame 8 is installed on the upper ends of the two side surfaces of the filter box 1, a clamping hole 9 is provided on the surface of the fixing frame 8, and the inner side of the clamping hole 9 is clamped and connected with the surface of the clamping column 306, a take-up plate 10 is arranged at the lower end of the filter box 1, and a placement frame 11 is arranged on the upper surface of the take-up plate 10, a filter membrane 12 is arranged on the upper end of the inner side of the placement frame 11, and a reverse osmosis membrane 13 is arranged on the lower end of the inner side of the placement frame 11;

At the same time, the filter tank 604 rotates at a high speed to throw out the cosmetic solution, and some impurities are trapped inside the filter tank 604. When the cosmetic solution passes through the filter membrane 12, the tiny impurities inside it will be intercepted and filtered, and the reverse osmosis membrane 13 will stop the microorganisms on its surface.
