Description

Technical Field

[0001] This invention relates to dental cleaning appliances, particularly to a device for removing residue from between teeth using replaceable dental floss, and more specifically, to a dental floss support device. Background Technology

[0002] Food particles trapped between teeth are difficult to remove effectively by brushing or rinsing. These particles easily breed bacteria, which can lead to dental problems such as gingivitis, periodontitis, and cavities. Current research has confirmed a close relationship between periodontitis and neurological diseases such as diabetes and Alzheimer's, as well as digestive and cardiovascular diseases. Effectively removing food particles from between teeth can reduce the occurrence of cavities and periodontitis, improve oral hygiene, and promote overall health. After meals, people usually use toothpicks, dental floss, or floss picks to remove food particles from between their teeth. Dental floss, also known as dental floss, is generally in the form of a strip. Floss picks are generally divided into single-line floss picks and parallel double-line floss picks.

[0003] In realizing the concept of this invention, the inventors discovered at least the following problems with related technologies: Using toothpicks to remove food particles from between teeth may accidentally injure the gums, and the hardness of toothpicks can widen the gaps between teeth, making it easier for food particles to remain, damaging periodontal tissues, and causing more serious periodontal disease. Using dental floss to remove food particles from between teeth requires wrapping a sufficiently long piece of floss around the middle fingers of both hands, pulling the floss taut with the middle fingers, and then using the index fingers to remove the food particles. This is difficult to operate, requires a high level of skill from the user, and the floss wrapped around the middle fingers cannot be used, resulting in waste. Single-line dental floss picks have a circular cross-section, making it difficult for the floss to enter small gaps between teeth. Forcing it in can still widen the gaps, damage the gums and other periodontal tissues, causing local bleeding or even inflammation. Parallel double-line dental floss picks are more expensive and difficult to widely promote. Furthermore, as disposable items, the floss picks themselves can pollute the environment. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a dental floss support device, which solves the problems of difficulty in operation and waste of dental floss when directly using dental floss to remove residue between teeth in related technologies.

[0005] To address the aforementioned technical problems, a specific embodiment of the present invention provides a dental floss support device, comprising: a handle section and a support section, wherein a first support rod and a second support rod are disposed on the support section, and the first support rod and the second support rod are movable relative to each other along the support section. The second support rod is located away from the handle section, the end of the first support rod away from the support section has a first clamping portion for clamping dental floss, and the end of the second support rod away from the support section has a second clamping portion for clamping dental floss.

[0006] Specifically, the support section includes a groove, wherein the second support rod is slidably disposed within the groove.

[0007] Specifically, the second support rod has a square cross-section at one end near the slide groove, and the outer side wall of the second support rod near the slide groove is provided with a first protruding ridge and a second protruding ridge, wherein the first protruding ridge and the second protruding ridge are arranged opposite to each other, and the top of the slide groove side wall wraps inward around the first protruding ridge and the second protruding ridge.

[0008] Specifically, the second support rod has a cavity at one end near the slide groove, a first elastic element is provided in the cavity, and a protrusion is provided at the outlet of the cavity. The protrusion abuts against the bottom of the slide groove under the elastic force of the first elastic element and applies elastic force to the bottom of the slide groove.

[0009] Specifically, a through hole is provided at one end of the slide groove away from the handle section. The through hole is adapted to the protrusion. When the bottom end of the second support rod moves to the through hole, the protrusion is locked in the through hole under the action of the elastic force of the first elastic element, and the second support rod cannot move in the slide groove.

[0010] Specifically, the device also includes a seesaw. The first support rod includes a guide pin, a stop, and a second elastic element, the elastic force of which is less than that of the first elastic element. The seesaw is rotatably positioned on the side of the support section away from the first and second support rods. Under the action of the elastic force of the second elastic element, the stop is engaged within the clamping jaws of the first clamping part, preventing the jaws of the first clamping part from closing. When the protrusion is engaged within the through hole, pressing one end of the seesaw causes it to rotate. The other end of the seesaw presses against the guide pin, which overcomes the elastic force of the second elastic element, disengaging the stop from the clamping jaws of the first clamping part. The first clamping part then clamps the dental floss.

[0011] Specifically, the stop portion is wedge-shaped, and the stop portion includes a first opposing wedge-shaped surface near the clamping opening of the first clamping portion and a second opposing wedge-shaped surface away from the clamping opening of the first clamping portion. The included angle of the first opposing wedge-shaped surface is greater than the included angle of the second opposing wedge-shaped surface.

[0012] Specifically, the dental floss support device further includes a first pinch plate and a second pinch plate, and the two side walls of the groove are hollowed out. Below the first protrusion, the second support rod has a first plate extending beyond the side wall of the groove through the hollowed-out portion of the groove side wall, and the first plate is perpendicular to the side wall of the second support rod. Above the top of the groove side wall, the second support rod has a second plate extending beyond the groove side wall, and the second plate is perpendicular to the side wall of the second support rod. One end of the first pinch plate is connected to the first plate, and the other end of the first pinch plate is connected to the second plate. Below the second protrusion, the second support rod has a third plate extending beyond the groove side wall through the hollowed-out portion of the groove side wall, and the third plate is perpendicular to the side wall of the second support rod. Above the top of the groove side wall, the second support rod has a fourth plate extending beyond the groove side wall, and the fourth plate is perpendicular to the side wall of the second support rod. One end of the second pinch plate is connected to the third plate, and the other end of the second pinch plate is connected to the fourth plate.

[0013] Specifically, the support section includes a groove, wherein the first support rod is slidably disposed within the groove.

[0014] Specifically, the first clamping part and the second clamping part clamp the dental floss from the left and right sides.

[0015] Specifically, the first support rod has a guide section at the end away from the support segment, and the guide section is a U-shaped gap parallel to the first support rod.

[0016] Specifically, dental floss support devices also include a floss cutter for quickly cutting dental floss.

[0017] According to the above embodiments of the present invention, dental floss is installed on a dental floss support device. The user holds the dental floss support device to remove residue between teeth. When using it next time, the dental floss on the dental floss support device can be directly replaced. This can at least partially solve the problems of difficulty in operation and waste of dental floss when directly using dental floss to remove residue between teeth in related technologies. Therefore, it can achieve the technical effect of convenient operation and saving dental floss.

[0062] This invention provides a dental floss support device. Dental floss is installed on the device, allowing the user to hold it and remove food residue between teeth. The floss can be reused after being replaced. This effectively removes food particles from between teeth without damaging gums or widening gaps. It saves floss, is easy to use, reduces user costs, and avoids the environmental pollution associated with floss picks, facilitating widespread adoption. Experiments show that the dental floss support device provided by this invention requires only 3-6 cm of floss (F) to effectively remove food particles from between teeth. If the floss (F) is wrapped around the middle fingers of both hands, and the index fingers and thumbs are used to control the floss, approximately 25 cm of floss (F) is needed for one wrap on each finger, and approximately 35 cm (F) is needed for two wraps on each finger. Therefore, the dental floss support device provided by this invention significantly saves on dental floss.

[0063] Figure 1 This is a schematic diagram of a dental floss support device provided in a specific embodiment of the present invention.

[0064] like Figure 1As shown, the dental floss support device may include a handle section 1 and a support section 2. The support section 2 is provided with a first support rod 21 and a second support rod 22. The first support rod 21 and the second support rod 22 are movable relative to each other along the support section 2, that is, at least one of the first support rod 21 and the second support rod 22 is movable relative to each other along the support section 2.

[0065] Specifically, the second support rod 22 is away from the handle section 1, the first support rod 21 has a first clamping part 211 for clamping dental floss F at one end away from the support section 2, and the second support rod 22 has a second clamping part 221 for clamping dental floss F at one end away from the support section 2.

[0066] In embodiments of the present invention, the first clamping part 211 and the second clamping part 221 can be clamps, and the handle section 1 and the support section 2 can be integrally formed or be two independent parts. The handle section 1 and / or the support section 2 can be made of plastic, metal, ceramic, glass, polymer, composite material, etc. The handle section 1 and the support section 2 may not be on a straight line. As shown in the figure, the included angle between the handle section 1 and the support section 2 is an obtuse angle, so that the first support rod 21 and the second support rod 22 are in a protruding position, making it convenient for the user to pinch or hold the handle section 1, and use the dental floss F held by the first clamping part 211 and the second clamping part 221 to remove residue between teeth.

[0067] In embodiments of the present invention, the support segment 2 is movably disposed on the handle segment 1 (for example, the support segment 2 is movably disposed on the handle segment 1 via a ball hinge), that is, the support segment 2 can be deflected left or right relative to the handle segment 1. For example, the support segment 2 can turn left or right relative to the handle segment 1. After the support segment 2 turns left relative to the handle segment 1, the dental floss support device is used to remove residue between the lower left or upper right teeth. After the support segment 2 turns right relative to the handle segment 1, the dental floss support device is used to remove residue between the lower right or upper left teeth. When the support segment 2 and the handle segment 1 are in the same plane, the dental floss support device is used to remove residue between the upper and lower incisors, making it convenient for the user to remove residue between the teeth.

[0068] The dental floss support device provided in the embodiments of the present invention can effectively remove food particles remaining between teeth, without damaging the gums or widening the gaps between teeth when flossing, and it saves dental floss, is easy to operate, reduces the cost of flossing for users, and avoids the environmental pollution caused by dental floss picks, making it easy to promote and use widely.

[0069] Figure 2 This is a schematic diagram of a second support rod sliding in a groove, provided as a specific embodiment of the present invention.

[0070] like Figure 2As shown, the support section 2 may include a groove 23, wherein the second support rod 22 is slidably disposed within the groove 23.

[0071] In an embodiment of the present invention, the second support rod 22 can slide within the groove 23 to move closer to or further away from the first support rod 21. When the second support rod 22 slides away from the first support rod 21 within the groove 23, the second clamping portion 221 on the second support rod 22 stretches the dental floss F, and the dental floss F clamped between the first clamping portion 211 and the second clamping portion 221 can ultimately be used to remove food particles remaining between teeth.

[0072] In embodiments of the present invention, such as Figure 8 As shown, a ball bearing H can be provided at the bottom of the second support rod 22 to reduce the friction between the bottom of the second support rod 22 and the slide groove 23, so as to facilitate the sliding of the second support rod 22 in the slide groove 23.

[0073] Figure 3 This is a schematic diagram of the structure of a second support rod provided in a specific embodiment of the present invention.

[0074] like Figure 3 As shown, the cross-section of the second support rod 22 near the slide groove 23 is square, and the outer side wall of the second support rod 22 near the slide groove 23 is provided with a first protrusion 222 and a second protrusion 223, wherein the first protrusion 222 and the second protrusion 223 are arranged opposite to each other, and the top of the side wall of the slide groove 23 wraps inward around the first protrusion 222 and the second protrusion 223.

[0075] In embodiments of the present invention, the first protruding ridge 222 and the second protruding ridge 223 can be integrally formed with the second support rod 22 or can be formed separately. The top of the side wall of the slide groove 23 wraps inward around the first protruding ridge 222 and the second protruding ridge 223, ensuring that the second support rod 22 can slide freely within the slide groove 23 without coming out of the slide groove 23.

[0076] Figure 4 This is another structural schematic diagram of a second support rod provided for a specific embodiment of the present invention.

[0077] like Figure 4 As shown, the second support rod 22 has a cavity 24 at one end near the slide groove 23. A first elastic element 25 is provided in the cavity 24, and a protrusion 26 is provided at the outlet of the cavity 24. The protrusion 26 abuts against the bottom of the slide groove 23 under the elastic force of the first elastic element 25 and applies elastic force to the bottom of the slide groove 23.

[0078] In embodiments of the present invention, the first elastic element 25 may be a spring or a sheet. The first elastic element 25 applies elastic force to the protrusion 26, which abuts against the bottom of the groove 23, so that the first convex ridge 222 and the second convex ridge 223 are always in contact with the top of the side wall of the groove 23, thereby maintaining the second support rod 22 in a stable sliding position within the groove 23.

[0079] Figure 5 This is a schematic diagram of a slide groove provided for a specific embodiment of the present invention.

[0080] like Figure 5 As shown, a through hole 231 is provided at one end of the slide groove 23 away from the handle section 1. The through hole 231 is adapted to the protrusion 26. When the bottom end of the second support rod 22 moves to the through hole 231, the protrusion 26 is locked in the through hole 231 under the action of the elastic force of the first elastic member 25, and the second support rod 22 cannot move in the slide groove 23.

[0081] In this embodiment of the invention, the protrusion 26 is engaged within the through hole 231, preventing the second support rod 22 from moving within the groove 23. The distance between the first support rod 21 and the second support rod 22 is fixed. At this time, the dental floss F held between the first clamping part 211 and the second clamping part 221 can be used to remove food particles remaining between teeth. By pressing the protrusion 26 from the outside of the groove 23 (i.e., the bottom surface of the groove 23) with a pointed object, the bottom end of the second support rod 22 can be removed from the through hole 231, meaning the protrusion 26 is no longer engaged within the through hole 231.

[0082] In an embodiment of the present invention, a second through hole can be formed near the through hole 231 of the groove 23. The second through hole is adapted to the protrusion 26. When the bottom end of the second support rod 22 moves to the second through hole, under the action of the elastic force of the first elastic member 25, the protrusion 26 is locked in the second through hole, and the second support rod 22 cannot move within the groove 23. By pressing the protrusion 26 from the outside of the groove 23 (i.e., the bottom surface of the groove 23) with a pointed object, the bottom end of the second support rod 22 can be removed from the second through hole, that is, the protrusion 26 is no longer locked in the second through hole. The user can lock the protrusion 26 in the through hole 231 or the second through hole as needed, that is, to achieve the pulling of different lengths of dental floss F between the first clamping part 211 and the second clamping part 221. For example, for adults with larger teeth, the protrusion 26 can be locked in the through hole 231, in which case the dental floss F is longer; for minors with smaller teeth, the protrusion 26 can be locked in the second through hole, in which case the dental floss F is shorter.

[0083] Figure 6 This is another structural schematic diagram of a dental floss support device provided for a specific embodiment of the present invention.

[0084] like Figure 6 As shown, the dental floss support device may further include a seesaw 3. The first support rod 21 includes a guide needle 212, a stop part 213, and a second elastic element 214. The elastic force of the second elastic element 214 is less than the elastic force of the first elastic element 25. The seesaw 3 is rotatably disposed on the side of the support section 2 away from the first support rod 21 and the second support rod 22. Under the action of the elastic force of the second elastic element 214, the stop part 213 is engaged within the clamping jaws of the first clamping part 211, preventing the clamping jaws of the first clamping part 211 from closing. At this time, the first clamping part 211 does not clamp the dental floss F, and the dental floss F can freely pass through the clamping jaws of the first clamping part 211.

[0085] Specifically, the second elastic element 214 can be a spring, a sheet, etc. One end of the second elastic element 214 is fixed to the top of the stop part 213, and the other end of the second elastic element 214 is fixed to the first support rod 21. The guide needle 212 can be a circular or square cylinder. One end of the guide needle 212 contacts the bottom end of the stop part 213, and the other end of the guide needle 212 contacts the seesaw 3. When the protrusion 26 is engaged in the through hole 231, pressing one end of the seesaw 3 causes the seesaw 3 to rotate. The other end of the seesaw 3 presses the guide needle 212, and the guide needle 212 overcomes the elastic force of the second elastic element 214 to pull the stop part 213 out of the clamp of the first clamping part 211. The first clamping part 211 clamps the dental floss F. The dental floss F fixed between the first clamping part 211 and the second clamping part 221 can remove residue between teeth.

[0086] In an embodiment of the present invention, the user presses the end of the seesaw 3 near the through hole 231 with his hand, overcoming the elastic force of the first elastic member 25, and the protrusion 26 exits from the through hole 231. The second support rod 22 can move in the slide groove 23. At this time, the stop part 213 is stuck in the clamping mouth of the first clamping part 211 under the action of the elastic force of the second elastic member 214, preventing the clamping mouth of the first clamping part 211 from closing again, and the dental floss F can freely pass through the clamping mouth of the first clamping part 211.

[0087] Figure 7 This is a schematic diagram of a stop portion provided in a specific embodiment of the present invention.

[0088] like Figure 7 As shown, the stop portion 213 is wedge-shaped, and the stop portion 213 includes a first opposing wedge-shaped surface 2131 near the clamping opening of the first clamping portion 211 and a second opposing wedge-shaped surface 2132 away from the clamping opening of the first clamping portion 211. The included angle of the first opposing wedge-shaped surface 2131 is greater than the included angle of the second opposing wedge-shaped surface 2132.

[0089] In the embodiments of the present invention, since the clamping opening of the first clamping part 211 does not need to be opened particularly large, the included angle of the first relative wedge surface 2131 is greater than the included angle of the second relative wedge surface 2132, which facilitates the stop part 213 to open the clamping opening of the first clamping part 211 under the action of the elastic force of the second elastic member 214, and the included angle of the clamping opening of the first clamping part 211 is not particularly large, so that the dental floss F can pass freely in the clamping opening of the first clamping part 211.

[0090] Figure 8 This is a schematic diagram of the structure of a kneading board provided in a specific embodiment of the present invention.

[0091] like Figure 8 As shown, the dental floss support device may also include a first pinch plate 4 and a second pinch plate 5. The two side walls of the slide groove 23 are hollowed out, that is, the two side walls of the slide groove 23 are provided with penetrating gaps, and the gaps extend along the length of the slide groove 23.

[0092] On the lower side of the first protruding ridge 222, the second support rod 22 is provided with a first plate 224. The first plate 224 extends through the cutout in the side wall of the slide groove 23 to the outside of the side wall of the slide groove 23, and the first plate 224 is arranged perpendicular to the side wall of the second support rod 22. On the upper side of the top of the side wall of the slide groove 23, the second support rod 22 is provided with a second plate 225. The second plate 225 extends to the outside of the side wall of the slide groove 23, and the second plate 225 is arranged perpendicular to the side wall of the second support rod 22.

[0093] One end of the first pinch plate 4 is connected to the first plate body, and the other end of the first pinch plate 4 is connected to the second plate body.

[0094] On the lower side of the second protruding ridge 223, the second support rod 22 is provided with a third plate 226. The third plate 226 extends through the cutout in the side wall of the slide groove 23 and beyond the side wall of the slide groove 23, and is arranged perpendicular to the side wall of the second support rod 22. On the upper side of the top of the side wall of the slide groove 23, the second support rod 22 is provided with a fourth plate 227. The fourth plate 227 extends beyond the side wall of the slide groove 23 and is arranged perpendicular to the side wall of the second support rod 22.

[0095] One end of the second pinch plate 5 is connected to the third plate 226, and the other end of the second pinch plate 5 is connected to the fourth plate 227.

[0096] In an embodiment of the present invention, the user uses their index finger and thumb to pinch the first pinch plate 4 and the second pinch plate 5 to facilitate the movement of the second support rod 22 within the slide groove 23. For example, the dental floss F is clamped by the second clamping part 221 on the second support rod 22; by pinching the first pinch plate 4 and the second pinch plate 5 with the index finger and thumb, the second support rod 22 is moved away from the handle section 1, and the second clamping part 221 on the second support rod 22 stretches the dental floss F; when the bottom end of the second support rod 22 moves to the through hole 231, under the action of the elastic force of the first elastic member 25, the protrusion 26 is engaged in the through hole 231, and the second support rod 22 cannot move within the slide groove. When the protrusion 26 is engaged in the through hole 231, the protrusion 26 presses one end of the seesaw 3, causing the seesaw 3 to rotate. The other end of the seesaw 3 presses the guide needle 212, which overcomes the elastic force of the second elastic member 214 and pulls the stop part 213 out of the clamping jaw of the first clamping part 211. The first clamping part 211 clamps the dental floss F. The dental floss F, which is fixed between the first clamping part 211 and the second clamping part 221, can remove residue between the teeth.

[0097] In embodiments of the present invention, the dental floss F is generally in the form of a strip, hence it is also called a dental strip. The first clamping part 211 and the second clamping part 221 clamp the dental floss F from the left and right. If the plane containing the first support rod 21 and the second support rod 22 is a first plane, and the plane containing the dental floss F is a second plane, the first clamping part 211 and the second clamping part 221 clamp the dental floss F from the left and right, making the first plane and the second plane parallel to each other. When using the dental floss F clamped in this way to remove residue between teeth, the dental floss F can cut into the gaps between teeth without widening them, and the dental floss F lies flat against the sidewalls of the teeth, effectively removing plaque.

[0098] Figure 9 This is a schematic diagram of a first support rod sliding in a groove, provided as a specific embodiment of the present invention.

[0099] like Figure 9 As shown, the support section 2 may include a groove 23, wherein the first support rod 21 is slidably disposed within the groove 23.

[0100] In an embodiment of the present invention, the first support rod 21 is slidably disposed within the slide groove 23 to move closer to or further away from the second support rod 22. That is, the first support rod 21 and the second support rod 22 can be interchanged.

[0101] Figure 10 This is a schematic diagram of the structure of a thread guide and a thread cutter provided for a specific embodiment of the present invention.

[0102] like Figure 10As shown, the first support rod 21 has a straight section 215 at the end away from the support section 2, and the straight section 215 is a U-shaped gap parallel to the first support rod 21.

[0103] In an embodiment of the present invention, when the second support rod 22 is moved away from the handle section 1, the second clamping part 221 on the second support rod 22 stretches the dental floss F. The dental floss F passes freely within the clamping jaws of the first clamping part 211. The straight part 215 keeps the plane where the dental floss F is located parallel to the plane where the first support rod 21 and the second support rod 22 are located. When using such dental floss F to remove residue between teeth, the dental floss F can cut into the gaps between teeth without widening the gaps. Moreover, the dental floss F lies flat against the sidewall of the teeth, which can effectively remove dental plaque.

[0104] In embodiments of the present invention, the dental floss support device may further include a floss cutter 6, which may be disposed on the first support rod 21. The floss cutter 6 can quickly cut the dental floss F. The floss cutter 6 may include a first blade and a second blade, which are arranged in a scissor shape (for example, forming an acute angle between the first blade and the second blade), and the first blade and the second blade cannot move relative to each other. When the dental floss F is pulled into the acute angle formed between the first blade and the second blade, the dental floss F is cut off, making it convenient to use.

[0105] In embodiments of the present invention, the dental floss support device may further include a first fixing terminal 216 and a second fixing terminal 228. Both ends of the dental floss F can be fixed to the first fixing terminal 216 and the second fixing terminal 228 respectively, preventing the taut dental floss F from slipping out of the first clamping part 211 or the second clamping part 221 during flossing, thus preventing the dental floss F from becoming loose and affecting its effectiveness in removing food particles remaining between teeth, thereby improving the reliability of the dental floss support device.

[0106] Figure 11A This is a schematic diagram of the structure of a first fixed terminal provided in a specific embodiment of the present invention. Figure 11B This is a schematic diagram of the structure of a second fixed terminal provided in a specific embodiment of the present invention.

[0107] like Figure 11AAs shown, the first fixed terminal 216 may include a first rod 2161, a first spring 2162, a first stop 2163, and a first pressure head 2164. The first rod 2161 movably passes through the first support rod 21 (i.e., the first rod 2161 can move freely along the through hole). The first stop 2163 is located at the end of the first rod 2161 near the second support rod 22. The first pressure head 2164 is located at the end of the first rod 2161 away from the second support rod 22. The first spring 2162 is located between the first stop 2163 and the first support rod 21, and is sleeved on the first rod 2161. The first spring 2162 applies a spring force to the first stop 2163, causing the first stop 2163 to always tend to move away from the first support rod 21. The first stop 2163 applies a force to the first rod 2161, causing the first pressure head 2164 to always abut against the first support rod 21. If dental floss F is wrapped around the first rod 2161, the first pressure head 2164 presses the dental floss F tightly onto the first support rod 21, and the dental floss F will not slip off the first rod 2161.

[0108] like Figure 11B As shown, the second fixed terminal 228 may include a second rod 2281, a second spring 2282, a second stop 2283, and a second pressure head 2284. The second rod 2281 movably passes through the second support rod 22 (i.e., the second rod 2281 can move freely along the through hole). The second stop 2283 is located at the end of the second rod 2281 near the first support rod 21. The second pressure head 2284 is located at the end of the second rod 2281 away from the first support rod 21. The second spring 2282 is located between the second stop 2283 and the second support rod 22, and is sleeved on the second rod 2281. The second spring 2282 applies a spring force to the second stop 2283, causing the second stop 2283 to always tend to move away from the second support rod 22. The second rod 2281 applies a force to the second pressure head 2284, causing the second pressure head 2284 to press tightly against the second support rod 22. If dental floss F is wrapped around the second rod 2281, the second pressure head 2284 will press the dental floss F tightly onto the second support rod 22, and the dental floss F will not slip off the second rod 2281.

[0109] In embodiments of the present invention, if the two ends of the dental floss F are fixed to the first fixing terminal 216 and the second fixing terminal 228 respectively, the taut dental floss F can be effectively prevented from slipping out of the first clamping part 211 or the second clamping part 221 when flossing. The dental floss F is always in a taut state. The dental floss F fixed on the dental floss support device can effectively remove food particles remaining between teeth, further improving the reliability of the dental floss support device.
