One end of the liquid absorbing strip is connected to the overflow patch, and the other end penetrates the outer sheath and is connected to the overflow patch. Extending into the inner disinfection core, under normal conditions, the overflow sleeve is in a convergent shape. At the same time, the leak-proof ball will seal the convergence hole, thereby protecting the alcohol disinfectant from escaping to the outside too quickly, and the outer sealing layer After being squeezed, on the one hand, the inner disinfection core will be squeezed to release the alcohol disinfectant, and on the other hand, the internal air will be squeezed to cause the convergence film to expand and expand outward. At this time, the overflow patch will also unfold accordingly, and it will expand from the outside. The alcohol disinfectant absorbed on the suction strip will escape into the hollow overflow layer to disinfect the air. At the same time, the heat absorbed during its evaporation can also be used to cool down.
