Description

Technical Field

[0001] The present invention relates to dental and oral cleaning equipment, and more particularly, to a dental flosser with a rotating device. Background Art

[0002] The spaces between teeth and tooth surfaces can be cleaned by a variety of methods, including brushing, mechanically driven water jets, toothpicks, etc., and by using dental floss, dental tape, or similar fine wires. Dental floss is a thin fiber rope that is commonly used to remove food particles and plaque from teeth.

[0003] The main cause of caries (cavities) and periodontal (gum and tooth root) disease is bacterial plaque that forms on the tooth surface. Once bacterial plaque is removed, it can re-form in less than 24 hours. Therefore, to maintain optimal dental hygiene and health, floss at least once a day.

[0004] Most people do not floss their teeth because traditional flossing is inconvenient and cumbersome. The use of a handheld flosser (also called a floss holder or floss pick) makes flossing more convenient and easier. A flosser usually consists of two arms extending from a thin plastic body (or handle) with the floss attached to the two arms. Traditional flossers are usually made of hard plastic material and the floss is held at a fixed tension between the two arms.

[0005] Therefore, a major disadvantage of conventional dental flossers is that the tension of the dental floss is fixed and cannot be adjusted as needed. Therefore, it is necessary to provide an improved handheld dental flosser, which has a device for adjusting the tension of the dental floss and can more effectively clean the contour area of ​​the tooth surface (including the front surface, the back surface and the interdental surface of the tooth).

[0006] Therefore, an object of the present invention is to provide an improved handheld dental flosser having a device for adjusting the tension of the dental floss and more effectively cleaning the contoured areas of the tooth surfaces (including the front surface, the back surface and the interdental surface of the teeth). Summary of the invention

[0007] In view of the deficiencies in the prior art, the object of the present invention is to provide a dental flosser that solves the above technical problems.

[0008] To achieve the above object, the present invention provides the following technical solutions: A dental flosser with a rotating device comprises a U-shaped portion, a handle portion, a receiving portion, a rotating device and dental floss, wherein the U-shaped portion comprises a first arm and a second arm spaced apart from each other, the second arm comprises a channel passing therethrough, the handle portion is connected to the U-shaped portion, the receiving portion is placed on the handle portion, the rotating device is detachably connected to the receiving portion, one end of the dental floss is connected to the first arm and the other end is connected to the rotating device, a portion of the dental floss extends between the first arm and the second arm, and the dental floss passes through the channel, the tension of the dental floss is increased / decreased by rotating the rotating device, the rotating device is fixed by the receiving portion, and the tension of the dental floss is maintained.

[0009] Furthermore, the rotating device includes a rotating disk, a reel, a limiting convex ring and a shaft, the shaft can be rotatably connected to the receiving part, the dental floss can be wound and stored on the reel, and the limiting convex ring can limit the dental floss between the reel and the rotating disk.

[0010] Furthermore, the receiving part includes a receiving seat and a rotating opening, the rotating opening is opened in the middle of the receiving seat, and the shaft cooperates with the rotating opening.

[0011] Furthermore, a limiting protrusion is provided on the limiting convex ring, and a plurality of limiting grooves arranged around the rotating opening are provided on the receiving seat, and the limiting protrusion cooperates with the limiting grooves.

[0012] Furthermore, the receiving seat is provided with at least one notch communicating with the rotating opening, so that the receiving seat can be bent by an external force.

[0013] Furthermore, a stopper is provided on the end of the shaft, the diameter of the stopper is larger than the rotating opening, and a stopper groove cooperating with the stopper is provided on the bottom of the receiving seat.

[0014] Furthermore, at least one groove is formed on the shaft, so that the shaft can be deformed when passing through the rotating opening.

[0015] Furthermore, the limiting protrusion and the limiting groove are both hemispherical, and two limiting protrusions are provided and are symmetrical about the axis.

[0016] Furthermore, the receiving portion and the handle portion are integrally formed.

[0017] Furthermore, a plurality of anti-skid protrusions are provided on the edge of the rotating disk.

[0018] By adopting the above technical solution, the beneficial effects of the present invention are: 1. Traditional dental flossers often have a fixed floss tension and cannot be adjusted according to the specific needs of the user and the size of the tooth gap. The present invention introduces a rotating device, which allows users to easily adjust the tension of the dental floss. By turning the rotating device, the user can increase or decrease the length of the dental floss, thereby adjusting its tension to make it more suitable for different tooth gaps and contours, thereby cleaning teeth more effectively.

[0019] 2. Since the tension of the dental floss can be adjusted, the present invention can more deeply clean the gaps between teeth and the hard-to-reach areas on the tooth surface. Whether it is the front surface, back surface or interdental surface of the teeth, the present invention can provide a better cleaning effect, helping users to thoroughly remove food residues and dental plaque, and reduce the risk of caries and periodontal diseases.

[0020] 3. The design of the rotating device of the present invention makes the use of dental floss more convenient and comfortable. Users no longer need to manually adjust the position and tension of the dental floss, but only need to simply rotate the rotating device. In addition, the design of the receiving part also makes it easy for users to fix and disassemble the rotating device, further improving the user experience.

[0021] 3. The design of the limiting convex ring, limiting groove and stopper enhances the stability of the rotating device, ensuring that it will not loosen or fall off during use, thereby improving the durability of the product.

[0022] 4. By providing a more effective cleaning method, the present invention helps users develop good oral hygiene habits. Regular use of the dental flosser of the present invention for teeth cleaning can significantly reduce the number of bacteria and the formation of dental plaque in the oral cavity, thereby maintaining the health and beauty of the oral cavity.

[0023] In summary, the dental flosser with a rotating device of the present invention exhibits significant advantages and beneficial effects in adjusting the tension of the dental floss, improving the cleaning effect, enhancing the user experience, enhancing durability and stability, and promoting oral health.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] Figure 1-4 This is a dental flosser 160 according to an embodiment of the present invention.

[0031] The dental flosser 160 includes a U-shaped portion 112 , a handle portion 114 , a rotating device 128 , a receiving portion 152 and dental floss 126 .

[0032] The U-shaped portion 112 includes a base 120, a first arm 122, and a second arm 124, which extend from both ends of the base 120. One end of a dental floss bundle 126 is fixedly connected to the end of the first arm 122 of the U-shaped portion 112, and the position of the dental floss bundle 126 relative to the first arm 122 of the U-shaped portion 112 remains unchanged. The other end of the dental floss bundle 126 is connected to a rotating device 128.

[0033] like Figure 2 As shown, the rotating device 128 can be separated from the handle portion 114, but can also be connected to the receiving portion 152 of the handle portion 114. The user can operate the rotating device 128 to achieve the retraction and release of the dental floss 126 to increase, reduce or maintain the tension of the dental floss.

[0034] The middle portion of the dental floss 126 is slidably mounted on the second arm 124 of the U-shaped portion 112 so that the middle portion of the dental floss 126 can slide relative to the second arm 124 of the U-shaped portion 112, that is, the middle portion of the dental floss bundle 126 can slide through the channel 129 in the second arm 124.

[0035] The rotating device 128 includes a rotating disk 154, a shaft 156, a stop ring 158 and a reel 168. The other end of the dental floss 126 is connected to the rotating device 128, preferably the reel 168. The receiving portion 152 includes a receiving seat 164, which surrounds a rotating opening 162, and the rotating opening is in the handle portion 114. The rotating opening 162 can also be in the base 120, and the base 120 can be a part of the handle portion. For example, the entire dental flosser can be U-shaped, and the base 120 can be held by the user, and the base 120 is the handle portion.

[0036] In use, the user can rotate the rotating device 128 in one direction (e.g., counterclockwise) to increase the tension of the dental floss 126. The user can also rotate the rotating device 128 in another direction (e.g., clockwise) to reduce the tension of the dental floss 126. If necessary, the user can also disconnect the rotating device 128 from the receiving portion 152 handle portion 114.

[0037] The rotating device 128 can be fixed to the handle portion 114 or the receiving portion 152, and the shaft 156 is pushed into the rotating opening 162. The shaft 156 may include one or more grooves 170 to allow the shaft to bend or clamp to fit the rotating opening 162 when passing through the rotating opening 162. The receiving portion 152 may also include one or more notches 172 that communicate with the rotating opening 162 to allow the shaft 156 to bend when pushed in. The end of the shaft 156 may include a stopper 174 having a diameter larger than the rotating opening 162 to keep the rotating device 128 rotatably fixed to the handle portion 114. The stopper 174 can be installed in a stopper groove 182 in the handle portion 114.

[0038] like Figure 4 As shown, the arc-shaped or circular stop ring 158 includes one or more hemispherical stop protrusions 176, which can be embedded in a hemispherical stop groove 178 complementary thereto in the receiving seat 164. Preferably, the rotating device 128 includes two protrusions 176 spaced 180° apart (for example, as Figure 3 3 o'clock and 9 o'clock positions on the clock shown in the figure), located on the surface of the limiting protrusion 158 opposite to the receiving seat 164. Preferably, the limiting groove 178 surrounds the rotating opening 162 and is arranged in a circle, such as Figure 2 shown.

[0039] The receiving seat 164 is preferably located in a rotation groove 180 in the handle portion 114. The rotating device 128 can be rotated on the receiving seat 164 to increase the tension of the dental floss. When the rotating device 128 is rotated, the stop protrusions 176 move upward and outward from the stop grooves 178 in which they are currently located, and then enter the adjacent stop grooves 178 in the rotation direction. The circular arrangement of the stop grooves 178 and the two opposing stop protrusions 176 allow the protrusions to rotate in either direction.

[0040] Due to the distance between the limiting protrusion 158 and the stopper 174 and the thickness of the handle portion 114, the limiting protrusion 176 is retained in the limiting groove 178. However, due to the flexibility of the limiting protrusion 158 material (e.g., plastic) and the shapes of the limiting protrusion and the limiting groove, when the rotating device rotates, the limiting protrusion 176 slides or rises to the outside of the limiting groove 178 and is then pressed into the adjacent limiting groove 178 in the rotation direction.

[0041] The edge 154 of the rotating disk is provided with a plurality of anti-skid protrusions 158, so that the user can rotate the rotating disk more conveniently and without slipping.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
