Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE This application relates to the field of flossing, and more particularly, to a breakaway dental floss holder. [Background technology]

[0002] Floss is a commonly used interdental cleaning tool and is widely recommended by dentists in and outside China. Commercially available floss can be divided into two categories according to the usage: "wrapped" and "holder" floss. Wrapped floss is a bundle of floss wrapped around a floss roll, and a part of it needs to be removed for use. Holder-type floss, also known as dental floss holder, is a product with floss pre-attached and does not require the user to fix the floss by themselves when using it. Although holder-type floss is easy to use, it is difficult to clean back teeth and is disposable, which is not environmentally friendly.

[0003] There are various types of self-fixing dental floss holders on the market, but the basic structure is the same. Both types include a handle and a holder. The handle and holder are fixed together to form a Y-shape overall. Due to the structure, the Y-shaped holder has obvious defects in terms of ease of use and effectiveness. First, this holder is held with one hand. The space in the oral cavity is narrow, and it is difficult to control the force when operating with one hand, making it difficult for the floss to enter and exit between the teeth or slide up and down between the teeth. If the gap between the teeth is very narrow, excessive force may be applied, which may damage the gums. Second, it is necessary to directly tighten and tension the floss when using it. Because the floss is thin, slippery, and elastic, it is troublesome to tighten it directly and it is easy to loosen. Third, the floss is almost flat. In a fixed-structure holder, the angle between the plane of the flat floss and the axis of the handle is fixed, making it difficult to find the appropriate angle and posture to clean the gap between the teeth. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present application is to provide a detachable dental floss holder which, by winding floss around two dental floss holder bodies, allows operation with both hands, enables cleaning between teeth throughout the entire mouth, makes it easy to control the force used when cleaning, prevents damage to the gums, and allows the tension of the floss to be freely controlled with both hands, preventing loosening, and further provides a wide range of cleaning means and enhances practicality. [Means for solving the problem]

[0005] In order to achieve the above object, the present application is achieved by the following technical solutions. A separable dental floss holder including two dental floss holder bodies, Each dental floss holder body includes a handle portion and a floss winding head, and the floss winding head has a horizontal thread groove and a vertical thread groove from top to bottom, the horizontal thread groove opening upward and the vertical thread groove opening to the side, the side of the vertical thread groove away from the opening is a vertical convex portion, and the portion between the horizontal thread groove and the vertical thread groove is a horizontal convex portion.

[0006] Furthermore, the cross section of the floss winding head is a flattened rectangle, and the cross sections of the longitudinal and lateral protrusions are rectangular.

[0007] Additionally, at the opening of the longitudinal thread groove there is a fillet transition portion which guides the floss to slide into the groove.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, two dental floss holder bodies are used to realize two-handed operation, making the interdental cleaning action rich and diverse. The floss coming out of the horizontal groove is used to clean the entire back teeth and the anterior teeth of the lower jaw, and the floss coming out of the vertical groove is used to clean the anterior teeth of the upper jaw. In addition, the force during cleaning is easy to control, which allows the floss to enter between the teeth stably and slowly to clean, preventing damage to the gums, and the distance between the dental floss holders can also be freely controlled with both hands. By shortening the distance between the dental floss holders, the floss can be in more contact with the teeth, and a wider range of the teeth and gum margins can be cleaned. In addition, the tension of the dental floss holder can be freely controlled by the distance between the hands. Compared with the structure of the conventional dental floss holder with a fixed mounting holder, the present invention can avoid the phenomenon of the floss loosening after tensioning, making it more flexible and practical.

[0013] Working Example As shown in Figs. 1 to 5, a separable dental floss holder is provided according to an embodiment of the present application. The separable dental floss holder includes two dental floss holder bodies 1, each of which includes a handle 2 and a floss winding head 3. The floss winding head 3 is provided with a transverse thread groove 4 and a longitudinal thread groove 5 from top to bottom, respectively, to guide and restrict the floss. The transverse thread groove 4 opens upward, and the longitudinal thread groove 5 opens to the side, so that the transverse thread groove 4 and the longitudinal thread groove 5 open perpendicularly to each other. The side away from the opening of the longitudinal thread groove 5 is a longitudinal protrusion 6, and the portion between the transverse thread groove 4 and the longitudinal thread groove 5 is a transverse protrusion 7. The openings of the longitudinal thread groove 5 of the two dental floss holder bodies 1 face each other.

[0014] When using, the dental floss holder body 1 is held with both hands so that the opening directions of the vertical thread grooves 5 of the dental floss holder body 1 held in the left and right hands face each other. Take about 12 cm of floss and wind it on the left dental floss holder, that is, press one end of the floss against the end of the dental floss holder body 1 with the thumb of the left hand, wind the floss around the horizontal thread groove 4 with the right hand and place it on the horizontal protrusion 7, then wind it around the vertical thread groove 5 and wind it around the vertical protrusion 6 2 to 3 times, then wind it around the horizontal thread groove 4 and place it on the horizontal protrusion 7, and wind the floss around the left dental floss holder. Then, wind the floss on the right dental floss holder. That is, as in the case of the left hand, first, press the end of the floss with the thumb of the right hand, wind the floss around the horizontal thread groove 4, place it on the horizontal protrusion 7, then wind it around the vertical thread groove 5, wind it around the vertical protrusion 6 2-3 times, then wind it around the horizontal thread groove 4, and place it on the horizontal protrusion 7, completing the floss winding on the right dental floss holder. After winding the floss, if you maintain the appropriate tension with both hands, the floss will not loosen. This method of attaching the floss is simple and convenient, sturdy and reliable, and can save floss. In the case of flat floss, care must be taken not to twist the dental floss when winding the floss. By always keeping the surface of the flat floss that comes into contact with the dental floss holder body in contact with the dental floss holder body 1, twisting of the flat floss can be avoided.

[0015] Alternatively, the floss may be made longer and all of the excess floss may be wound around one of the vertical projections 6 of the dental floss holder body 1. In this way, floss that becomes dirty or damaged during use can be replaced. The method is to first pull out the floss from the vertical thread groove 5, then rotate the left dental floss holder to unwind the thread, and synchronously wind the thread from the right dental floss holder, thus winding up the used floss and winding up new floss, and renewing the floss.

[0016] The floss may be simultaneously drawn out from the horizontal grooves 4 of the two dental floss holder bodies 1, and may be simultaneously drawn out from the vertical grooves 5. With these two drawing methods, the plane of the flat floss is parallel or perpendicular to the axial direction of the dental floss holder body 1. The conversion of the floss between the horizontal grooves 4 and the vertical grooves 5 is also easy enough, and can be achieved by simply flipping the dental floss holder body 1 with both hands at the same time. The floss coming out of the horizontal grooves 4 is used to clean the entire back teeth and the anterior teeth of the lower jaw, and the floss coming out of the vertical grooves 5 is used to clean the anterior teeth of the upper jaw.

[0017] The present invention realizes two-handed operation, provides rich and diverse interdental cleaning actions, and makes it easy to control the force during cleaning. It allows the floss to enter between the teeth stably and slowly to clean, and prevents damage to the gums. In addition, the distance between the dental floss holders can be freely controlled with both hands. By shortening the distance between the dental floss holders, the floss can come into contact with the teeth more, and a wider range of the teeth and gum margins can be cleaned. In addition, the tension of the floss can be freely controlled by the distance between the hands, and loosening can be avoided.

[0018] The above description is merely a preferred embodiment of the present application, and does not limit the present application. Those skilled in the art can make various modifications and variations to the present application. Any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and principles of the present application shall be included in the scope of protection of the present application.
