[0075] The implementation principle of a hand-washing mirror with a bacteria reminder function in the embodiment of the present application is as follows:

[0076] After the child washes his hands, he wipes his hands dry on the paper towel 22. When the child wipes his hands on the paper towel 22, the paper towel 22 is pulled so that the paper towel 22 moves from the outlet 212 to the inlet 211. The movement direction of the paper towel 22 from the outlet 212 to the inlet 211 is a trigger signal. The photoelectric sensor 8 sends the trigger signal to the control system. After receiving the trigger signal and waiting for a suitable time, the control system controls the first winding motor 521 and the second winding motor to start and run synchronously. After the first winding motor 521 and the second winding motor are turned on and run continuously for 3 seconds, the first winding motor 521 and the second winding motor suspends operation for 5s. When the first winding motor 521 is just paused, the control system immediately controls the purple light source 231 to turn on. After the purple light source 231 is turned on for 1s, the control system controls the camera 232 to shoot. When the control system receives the image sent by the camera 232, the control system controls the purple light source 231 to turn off. Then, the first winding motor 521 and the second winding motor continue to run for 5s. The control system controls the drive motor 64 to turn on and run, so that the cutting shear 56 cuts the hand towel 22. The cut hand towel 22 enters the waste paper bin 7 through the outlet 212 to avoid polluting the hand washing environment.

[0077] After the control system receives the image sent by the camera 232, the control system determines whether the hands have just been washed based on whether there are fluorescent spots on the image;

[0078] When the control system determines that the hands are clean, the control system controls the display 13 to display a "smiley face" animation and plays a voice message "Little friend, your hands are washed very clean, you are great!" to praise the child;

[0079] If the control system determines that the hands are not clean, it controls the display 13 to display a "crying face" animation and play a voice message saying, "Little friend, your hands are not clean. Please wash them carefully again!" This provides a fun reminder for the child, encouraging them to wash their hands carefully again. This helps the child know whether they have washed their hands cleanly and realize the importance of hand hygiene in a relaxed and happy atmosphere.

[0080] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
