A liquid storage tank 8 is fixedly connected to the top of the top plate 3, and a liquid pump 9 is fixedly connected to the top of the top plate 3. The input end of the liquid pump 9 is fixedly connected to the liquid storage tank 8, and the output end of the liquid pump 9 is fixedly connected to the connecting pipe 707.

[0024] The effect achieved by the entire embodiment 1 is that when the sanitary napkin is subjected to reverse osmosis detection, the sanitary napkin is laid flat in the placement box 4, and then the detection liquid stored in the liquid storage tank 8 is extracted by the liquid extraction pump 9, and the liquid is transported to the position of the connecting block 704 through the connection between the connecting pipe 707 and the bellows 706, and the detection liquid is sprayed on the surface of the sanitary napkin from the position of the nozzle 705.
