Water Drop Toothbrush / Dental equipment

Water Drop Toothbrush
Water Drop Toothbrush

Water Drop Toothbrush is a set of dental appliances that help children develop good brushing habits. When brushing teeth, only the kinetic energy that generated by the action of brushing up and down can be converted into electric energy. It means that the brushing time is already 3 minutes, when all three lights are on. The handle of the toothbrush transfers energy through contacting with the slot, so that the light disappears after the toothbrush is placed in the cylinder,and with at least 6 minutes can the cylinder maintain the gums as a night light for 3 hours of soft lighting.
