The appearance of dental floss in the market makes the masses of people profit from it. Compared with toothpicks, the dental floss can effectively remove residual substances in tooth gaps and dental plaques on adjacent surfaces of teeth, thereby keeping periodontal health. There are three main known methods of using dental floss, one is the use of an F-shaped floss pick, the other is the use of direct hand-wound floss, and the third is the use of an automatic type floss pick. For the F-shaped dental floss rod, the manufacturing cost is high, and the plastic frame is manufactured and can be lost when being used, so that the F-shaped dental floss rod is not environment-friendly; secondly, cleaning one time of teeth usually uses a plurality of F-shaped dental floss sticks, which causes great waste. In the case of a wound floss, each time it is used, it is wasted because it requires a portion of floss to be wound around the fingers in addition to the portion of floss required to clean the teeth; and the inconvenience is caused by the need of moving the hand in the oral cavity when in use. Aiming at the automatic dental floss device, the structure is complex, the number of parts is large, the price is high, and the number of users is small.
Although the existing floss device with replaceable floss is environment-friendly, the floss is fixed by winding the floss at two ends, so the winding process is too troublesome; the dental floss has poor fixing effect, and is often loosened after force is applied to the dental floss in use, so that the dental floss is not thoroughly cleaned.
