[0053] When applying the medicine liquid, the lifting seat 9 moves upward to drive the protrusion 901 to push the long dial block 805 upward, that is, to drive the sliding cover 8 to move upward to open the entrance, and drive the limit block 802 to abut against the inner top of the medicine storage box 6. At this time, the medicine liquid will enter the guide cavity 904 in the lifting seat 9 through the guide rubber sheet 402, and be evenly immersed on the cotton wool 503 through the guide hole 905. After the medicine application is completed, the lifting seat 9 immediately drives the protrusion 901 upward to pass over the long dial block 805, and the fourth spring 804 drives the limit block 802 to reset, and the sliding cover 8 to reset and close the medicine inlet 401.

[0054] After applying the medicine, the lifting seat 9 moves upward until it reaches the ascending tooth plate 305, and continues to move upward to drive the ascending tooth plate 305 to move upward, and drives the descending tooth plate 408 to move down to a suitable position through the gear 304, that is, drives the smear barrel 4 to move down to a suitable position, which is convenient for more stable contact with the affected area and convenient for smearing. Subsequently, the screw rod 103 rotates to drive the smear barrel 4 to move a certain amount, so that the cotton wool 503 can be applied to the affected area. After the application of the medicine is completed, the lifting seat 9 pushes the cotton wool 503 downward to enlarge the space between the opening and closing plates 403, thereby facilitating the discharge of the cotton wool 503 and the disposable use of the cotton wool 503, effectively avoiding the occurrence of cross infection. It is hygienic and convenient to use, and flexible and convenient to operate.
