The present invention relates to the technical field of interdental cleaning, and in particular, can effectively solve the problem of having debris stuck between the teeth and can remove dental plaque.
Common interdental cleaning tools currently available on the market include: boxed dental floss, floss sticks and composite-material floss holders. The recommended flossing technique by manufacturers of boxed dental floss is to wind the floss around the fingers to clean in-between the teeth, the drawback of which is the difficulty in cleaning between the molar teeth at the back. The floss sticks have the following problems: 1. floss sticks are generally made of plastic, and the U-shaped arches thereof made of plastic have insufficient rigidity, such that the dental floss is relatively slack during use, leading to a poor cleaning effect; 2. floss sticks have an F-shaped overall structure, making it very difficult to clean in-between the molar teeth at the back; and 3. floss sticks are products for one time use and is disposed of after use, resulting in resource waste and generation of a lot of hard-to-degrade domestic waste. The composite-material floss holders are too complicated in structure, leaving spaces where impurities or germs may accumulate during long-term use and render the structure difficult to clean and disinfect.
The present invention provides an interdental cleaning tool considering the above state of the art.
The technical scheme adopted by the present invention is an interdental cleaning tool including a floss holder and dental floss. The floss holder is made of a stainless steel wire and composed of a U-shaped arch and a handle: the angles between the two arms of the U-shaped arch and the arch bottom, and between the arch bottom and the handle, are both 90 degrees with a rounded transition; each end of the U-shaped arch is provided with a ring groove; and a gap is provided at the distal end of the handle between the two segments of the steel wire of which the handle is made, and the two segments of the steel wire of the remaining part of the handle should be tightly attached together. The dental floss is wound at the ring grooves of the two ends of the U-shaped arch, the winding method including: pressing one end of the dental floss with a thumb at the ring groove of either end of the U-shaped arch, around which winding the dental floss clockwise in 15 turns; tightening the dental floss at the ring groove of the other end of the arch, then winding the dental floss clockwise in 10 turns first; hooking the free end of the dental floss to the dental floss between the two ends of the U-shaped arch; tightening the floss counterclockwise, and then winding it counterclockwise in five or six turns; and after the winding is finished, clamping the end of the dental floss in the gap in the middle of the handle for fixation.
The effect of the present invention is that the interdental cleaning tool of the present invention can be used with various types of dental floss. The floss holder body is made of a stainless steel wire and can be used repeatedly. The interdental cleaning tool has a smooth surface and a high hardness, is simple in structure and easy to clean after use, and can be disinfected at a high temperature. The floss holder is generally Y-shaped with a simple and compact structure, allowing flexible operations at different angles, such that each gap between the teeth can be conveniently cleaned. The U-shaped arch part of the floss holder is made of a stainless steel wire, thereby having a high rigidity, which together with the winding method described herein ensures sufficient tension of the dental floss, such that even food fibers which are wedged tightly between teeth can be easily removed.
The interdental cleaning tool provided in the present invention is further described herein with reference to the drawings. Referring to
