Description

Technical Field

[0001] The invention belongs to the technical field of oral care, in particular to a dental floss stick for cleaning teeth. Background Art

[0002] A dental floss stick usually consists of a U-shaped dental floss holder and a handle. The tail of the handle is designed as a toothpick, and the two ends of the dental floss on the dental floss stick are fixedly connected to the two ends of the U-shaped opening of the dental floss holder. The function of the dental floss stick is to remove food residues in the gaps between teeth and to remove dental plaque and soft deposits on the tooth surfaces on both sides of the gaps. The dental floss on the dental floss holder is commonly designed in three forms: single dental floss, double parallel dental floss and double "X" shaped cross dental floss. However, no matter what design arrangement the dental floss is on the dental floss stick, the dental floss can only be pressed into the gap between teeth in a sawing manner until the gums begin to be cleaned. When using it, the dental floss is horizontally in the gap between teeth. The dental floss is placed close to the teeth on one side of the gap, and the dental floss is repeatedly pulled toward the top of the gap (the vertical direction of the horizontal dental floss) to form a scraping surface on the tooth surface. Food residues, dental plaque and soft deposits on the tooth surface are removed from the top of the gap between teeth as the dental floss is pulled upward. If the dental floss is pulled along the inner and outer gaps of the teeth in the direction of the horizontal dental floss, the pulling force on the food residues, dental plaque and soft deposits is linear sliding friction, which is extremely small and has no cleaning effect. Therefore, the dental floss stick is not used for horizontal pulling in the gaps between teeth to clean food residues, dental plaque and soft deposits. This kind of dental floss stick that can only be pulled upward but not horizontally for cleaning has the following two disadvantages: Disadvantage 1: When encountering larger food residues that are close to the teeth, especially when the teeth are filled with food residues, the dental floss cannot be pressed into the gums laterally. The dental floss can only slide on the surface of the food residues and cannot form a scraping surface on the tooth surface, so the food residue cannot be cleaned. If forceful pressure is applied in an attempt to press the dental floss into the food residues, the food residues will be further squeezed, and the food residues will be more tightly attached to the teeth gaps, making it more difficult to clean the food residues out of the top gaps between the teeth. At the same time, the dental floss cannot be pressed into the gums laterally, and there is no way to clean the plaque and soft deposits on the tooth surface. The "X"-shaped cross design of the double dental floss has the intersection point located at the center point of the two dental flosses. The resistance to pressing the dental floss into the food residues is greater, making it more difficult to clean the food residues out of the teeth gaps.

[0003] The second disadvantage is that the characteristics of the gaps between teeth are that the gaps on the inside and outside sides of the lower teeth are wide, and the gaps between the top teeth are narrow. It is difficult to clean out the larger food residues that fill the gaps between teeth through the narrow gaps between the top teeth. The best way should be to use the wide gaps on both sides of the lower part of the teeth to clean them out from the lower part of the gaps between the inner and outer sides of the teeth. However, the characteristic of the dental floss stick that the dental floss is always horizontal in the gaps between teeth determines that the dental floss stick does not have the function of pulling horizontally along the inner and outer gaps between teeth to clean food residues.

[0004] Due to the above two shortcomings, when encountering large food residues that are close to the teeth, especially when the teeth are filled with food residues, the dental floss stick cannot be used directly. Usually, a toothpick must be used to remove the larger part of the food residue as much as possible to loosen the remaining food residues, and then the dental floss can be pressed horizontally into the teeth until it reaches the gums, thereby cleaning the remaining food residues and cleaning dental plaque and soft scale. This is why the tail of the dental floss stick handle is usually designed to be used as a toothpick for removing food residues first. Using a toothpick is very harmful to the gums. Since the dental floss stick must be pressed horizontally into the gums to clean food residues, dental plaque and soft scale, long-term use will also cause great damage to the gums, and it is a dental floss stick that damages the gums. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a dental floss stick that can form a net bag-like covering for food residues while retaining the existing upward pulling and cleaning function, so that the dental floss stick has the function of clamping and pulling food residues horizontally along the inner and outer interdental gaps of the teeth, and cleaning the food residues through the wide gaps on both sides of the lower part of the interdental gaps, thereby solving the problem that the prior art is difficult to clean large, tightly attached and filled food residues; by clamping and pulling food residues horizontally along the inner and outer interdental gaps of the teeth to clean, the dental floss can complete the cleaning without almost touching the gums, and does not damage the gums.

[0006] (II) Technical solution To achieve the above object, the present invention is implemented in the following ways: 1. A dental floss stick, comprising a dental floss rack, two end rods of the dental floss rack opening, and dental floss, wherein the dental floss is a dental floss bundle consisting of two or more dental flosses, the two ends of the dental floss bundle are correspondingly fixedly connected to the two end rods of the dental floss rack opening, and the distance X between the center points of the cross sections of two adjacent dental flosses at the fixed connection points of the two end rods of the dental floss rack opening is less than the sum D of the radii of the two adjacent dental flosses.

[0007] 2. A dental floss stick, comprising a dental floss rack, two end rods at the end of the dental floss rack opening, and dental floss, wherein the dental floss is a dental floss bundle consisting of two or more dental flosses, the two ends of the dental floss bundle are correspondingly fixedly connected to the two end rods at the end of the dental floss rack opening, and the distance X between the center points of the cross-sections of two adjacent dental flosses at the fixed connection points of the two end rods at the end of the dental floss rack opening is greater than or equal to the sum of the radii D of the two adjacent dental flosses and is less than D plus 0.8 mm.

[0008] 3. A dental floss stick, comprising a dental floss rack, two end rods of the dental floss rack opening, and dental floss, wherein the dental floss is a dental floss bundle consisting of 2 to 4 dental flosses, the two ends of the dental floss bundle are correspondingly fixedly connected to the two end rods of the dental floss rack opening, and the distance X between the center points of the cross sections of two adjacent dental flosses at the fixed connection points of the two end rods of the dental floss rack opening is less than the sum D of the radii of the two adjacent dental flosses.

[0009] 4. A dental floss stick, comprising a dental floss rack, two end rods at the opening of the dental floss rack, and dental floss, wherein the dental floss is a dental floss bundle consisting of 2 to 4 dental flosses, the two ends of the dental floss bundle are correspondingly fixedly connected to the two end rods at the opening of the dental floss rack, and the distance X between the center points of the cross-sections of two adjacent dental flosses at the fixed connection points of the two end rods at the opening of the dental floss rack is greater than or equal to the sum of the radii D of the two adjacent dental flosses and is less than D plus 0.8 mm.

[0010] The dental floss of the present invention has two ends, and the ends on the same side of each dental floss are gathered together to form a dental floss bundle end, which is fixedly connected to the rods at the two ends of the dental floss rack opening. The other parts of the dental floss are parallel to each other without connection or entanglement. When the dental floss bundle is pressed horizontally into the tooth gap and contacts the food residue, it only needs to be lightly pressed on the surface of the food residue and moved back and forth. The elastic characteristics of the dental floss make the dental floss in the middle section of the dental floss bundle elastically separate due to the food residue, thereby forming a net bag-like covering for the food residue with the two bundle ends gathered in the middle. At this time, it is pulled horizontally along the inner and outer tooth gaps of the teeth in a sawing manner, and the two bundle ends of the gathered dental floss bundle will exert a large pulling force on the food residue. Compared with the linear sliding friction between the dental floss and the teeth in the existing dental floss stick, the pulling force will be sufficiently improved, and is large enough to loosen the food residue stuck in the tooth gap, tear the surface layer of the food residue, clamp and drag it out of the tooth gap, and it is a horizontal pulling, and will not compact the food residue. The web-like covering formed by the dental floss bundle only contacts the food residues and hardly touches the gums, causing no damage to the gums. After the food residues are cleaned, the dental floss is then used to clean dental plaque and soft scale. The method of pulling the dental floss stick upward can also be used to clean dental plaque and soft scale. The difference is that the dental floss bundle is composed of multiple parallel overlapping dental floss. When the same pressure is applied to touch the gums, the pressure on the gums will be greatly reduced compared with that of a single dental floss pressed into the gums, and the damage to the gums will also be greatly reduced. When the dental floss bundle is pulled upward to clean dental plaque and soft scale, multiple dental flosses clean the tooth scraping surface at the same time. Compared with cleaning with a single dental floss, the cleaning efficiency and effect are doubled. The dental floss bundle of the present invention has the best effect when 2 to 4 dental flosses are formed into a net bag-like covering. The number of dental flosses in the dental floss bundle should not be too many, and should not exceed 6 at most. Otherwise, it is difficult to press them into the teeth, and too many dental flosses will easily become entangled with each other and difficult to separate to form a net bag-like covering.The effect of the net-bag-like coverage formed by the dental floss bundle also depends on the length of the distance X between the center points of the cross-sections of adjacent dental floss ends at the connection points of the dental floss bundle ends and the rods at the two ends of the dental floss rack opening. When X is greater than the sum of the radii of two adjacent dental floss D plus 0.8 mm, the dental floss in the dental floss stick is arranged in parallel and completely isolated from each other, and a net-bag-like coverage cannot be formed. When X is less than or equal to the sum of the radii of two adjacent dental floss D plus 0.8 mm, an effective net-bag-like coverage can be formed. When the dental floss bundle is pulled horizontally, the two bundle ends can exert a certain pulling force on the food residue. In particular, when X is less than D, the dental floss ends at the bundle ends of the dental floss bundle fixedly connected to the rods at the two ends of the dental floss rack opening will partially or completely overlap together. At this time, the rest of the dental floss that makes up the dental floss bundle is in a parallel overlapping state. After the net-bag-like coverage is formed, the pulling force generated by pulling the food residue horizontally is the largest, and the effect of cleaning the food residue is the best.

[0011] (iii) Beneficial effects, Due to the adoption of the above technical solution, the present invention has the following main features: (1) The dental floss stick has the function of cleaning food residues by pulling it horizontally along the inner and outer interdental spaces, so that the dental floss stick has the ability to clean larger and tighter interdental spaces or even those that are clogged with food residues, thereby solving the problem that food residues that are clogged and difficult to clean by pulling it upward. The dental floss stick has become a dual-function dental floss stick that can be pulled upward and pulled horizontally for cleaning.

[0012] (2) The dental floss stick is used for upward pulling and cleaning. Compared with the existing technology, it causes less damage to the gums and the cleaning efficiency is doubled.

[0013] (3) The dental floss stick cleans food residue horizontally without touching the gums, causing no damage to the gums. It is a non-damaging gum dental floss stick. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 3 This is a schematic diagram of the dental floss bundle of the present invention being divided into a net bag-like covering in the middle when in use. DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: In the attached drawings, 1 is a dental floss rack, 2 is a handle, 3 is a right end rod of the dental floss rack, 4 is a fixed connection point between the right end of the dental floss bundle and the right end rod 3 of the dental floss rack, 5 is a dental floss bundle, 6 is dental floss 1, 7 is dental floss 2, 8 is a left end rod of the dental floss rack, 9 is a fixed connection point between the left end of the dental floss bundle and the left end rod 8 of the dental floss rack, 10 is the center point of the cross section of dental floss 1 6, and 11 is the distance between the center points of the cross sections of dental floss 1 6 and dental floss 2 7 (attached Figure 2 The dotted line (X, 12) is the center point of the cross section of the dental floss 7.

[0018] In this embodiment, two dental flosses (dental floss 1 6 and dental floss 2 7) form a dental floss bundle 5. Usually, dental floss 1 6 and dental floss 2 7 are in a state of being largely parallel and overlapping. On the left and right end rods of the dental floss rack, the dental floss bundle 5 is connected. The left end of the dental floss bundle formed by the dental floss 1 6 and the left end of the dental floss 2 7 is fixedly connected to the connection point 9 of the left end rod of the dental floss rack. The right end of the dental floss bundle formed by the dental floss 1 6 and the right end of the dental floss 2 7 is fixedly connected to the connection point 4 of the right end rod of the dental floss rack. 11 is the distance X between the center point 10 of the cross section of the dental floss 1 6 and the center point 12 of the cross section of the dental floss 2 7 (the dotted line portion in the figure). The shorter X is, the closer the two ends of the dental floss bundle are gathered, and the greater the pulling force on the food residue after forming a net bag-like covering. The sum of the radii of the dental floss 1 6 and the dental floss 2 7 is D, and usually the diameters of the two dental flosses are the same. When X is less than D, the circumferences of dental floss 1 6 and dental floss 2 7 intersect and overlap, and the other parts of dental floss 1 6 and dental floss 2 7 overlap and overlap in parallel, forming a net bag-like covering, which generates the greatest pulling force on food residues, and the effect of cleaning food residues in a bag-like manner is the best. Only the ends of dental floss 1 6 and dental floss 2 7 are fixedly connected together to form a dental floss bundle end, and the other parts of dental floss 1 6 and dental floss 2 7 are parallel to each other and not connected. This allows the dental floss bundle to be pressed into the gap between teeth. No matter which direction it contacts the food residue, as long as it is lightly pressed on the surface of the food residue and moved back and forth, the dental floss in the middle of the dental floss bundle will be elastically separated due to the food residue, thereby forming a net bag-like covering for the food residue with the middle separated and the two ends gathered into a bundle, as shown in the attached Figure 3 As shown in the figure, the dental floss 1 6 and the dental floss 2 7 that make up the dental floss bundle 5 are separated. At this time, the dental floss bundle is repeatedly pulled horizontally along the inner and outer interdental gaps of the teeth in a sawing manner. The two bundled ends of the dental floss bundle will exert a sufficiently large pulling force on the food residue, and the food residue stuck in the interdental gap will loosen. The residue on the surface will be torn apart and clamped and dragged to clean out of the interdental gap. This is repeated until all the food residues are cleaned. After cleaning the food residues, the same method is used to clean dental plaque and soft scale. It can also be used in combination with the existing dental floss stick cleaning method. When the present invention is implemented, the dental floss bundle is pressed into the interdental gap, and the dental floss 1 6 and the dental floss 2 7 will separate from the middle section of the dental floss and enter the interdental gap separately, which is the same as the difficulty of pressing a single dental floss on an existing dental floss stick into the interdental gap.

[0019] In actual application, the present invention may further provide two or more dental floss bundles on the dental floss rack based on the above embodiments to further improve the effect of the invention. However, these designs are not essentially different from the present invention and all fall within the scope of protection of the present invention.
