Description

Technical Field

[0001] This utility model relates to the technical field of dental floss picks, and more particularly to a dental floss pick. Background Technology

[0002] Dental floss picks are a common oral hygiene tool used to remove plaque and food debris from the interproximal surfaces of teeth and the gum line. Traditional dental floss picks typically consist of a handle and a straight floss holder, with the floss fixed at both ends of the holder. However, existing dental floss picks have the following drawbacks: (1) Insufficient floss tension: Traditional straight or simple curved floss holders are prone to deformation under stress, leading to floss loosening and reduced cleaning effectiveness; moreover, the floss fixing method is limited, making it easy for the floss to shift or fall off during use; (2) Low structural strength and easy breakage: The connection between the floss holder and the handle or the floss fixing point is prone to breakage due to stress concentration, affecting the service life; the lack of a transition structure leads to fatigue damage of the floss holder after repeated stress. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The technical problem this invention aims to solve is to provide a dental floss pick that, through the cooperation of a straight section and two curved sections, forms a stable triangular support structure, enhancing floss tension and improving cleaning efficiency. The transition section avoids stress concentration, reduces the risk of floss holder breakage, and extends service life. The curved sections bend outward from both ends of the axis, expanding the floss coverage area and facilitating cleaning of hard-to-reach areas such as molars. This solves the problems of traditional dental floss picks, such as easy floss loosening, easy breakage, and inconvenient operation, thereby improving cleaning effect and service life.

[0005] (II) Technical Solution

[0006] The solution adopted by this utility model to solve the above-mentioned technical problem is a dental floss pick, which includes...

[0007] The handle is for the user to hold.

[0008] A dental floss holder is located at one end of the handle portion; the dental floss holder is Y-shaped and includes a straight portion and two curved portions, one end of each of the two curved portions being joined to the same end of the straight portion to form a Y-shaped dental floss holder; wherein, the two curved portions extend and bend from the joining point toward both ends of the axis of the straight portion, and a transition portion is provided between the straight portion and the two curved portions;

[0009] Dental floss is a floss that connects two curved sections at the ends away from the straight section.

[0010] The above solution forms a stable triangular support structure through the combination of the straight section and the two curved sections, which enhances the tension of the dental floss and improves cleaning efficiency. The transition section avoids stress concentration, reduces the risk of dental floss holder breakage, and extends service life. The curved section bends outward from both ends of the axis, expanding the coverage area of ​​the dental floss and making it easier to clean hard-to-reach areas such as molars.

[0011] In some embodiments, two curved portions and two transition portions are formed by bending downward along the axis of the handle portion and forming a continuous curved surface at the lower end. The curved surface is a three-dimensional curved surface with curvature in a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0012] Specifically, the first direction, the second direction, and the third direction are the X-axis, Y-axis, and Z-axis directions of a spatial rectangular coordinate system; the surface exhibits arc-shaped changes in the X-axis, Y-axis, and Z-axis directions of the spatial rectangular coordinate system; the projection of the surface onto the XY plane is arc-shaped, the projection onto the XZ plane is arc-shaped, and the projection onto the YZ plane is also arc-shaped, forming a three-dimensional surface with continuous curvature changes in three orthogonal directions.

[0013] In some embodiments, two curved portions meet at the confluence of their straight portions in a direction toward each other to form a connection; and the connection and the two curved portions form a U-shaped opening for receiving and tensioning dental floss.

[0014] The above solution forms a U-shaped opening through the connecting part and the curved part, which is used to fix the dental floss and prevent it from loosening or shifting during use. It can also automatically maintain the tension of the dental floss and improve the cleaning effect.

[0015] In some embodiments, the connecting portion and the two curved portions extend inwardly from the inner wall of the U-shaped opening to form an extension wall, the extension wall being U-shaped.

[0016] Using the above method, the U-shaped extension wall is thinner than other parts during injection molding, and it is cooled and fixed first during cooling to form a floss holder, allowing the U-shaped opening to contract along the outer sides at both ends, thereby tightening the floss.

[0017] In some embodiments, the wall thickness of the extended wall is less than the wall thickness of the connecting portion and the two curved portions.

[0018] By adopting the above scheme, the thickness of the extension wall is less than the thickness of its outer wall, which can effectively control the shrinkage and deformation of the dental floss holder and tighten the dental floss.

[0019] In some embodiments, the width of the straight portion gradually increases toward the curved portion, such that the two side walls of the straight portion form arc-shaped walls that respectively connect with the two transition portions.

[0020] The above solution allows for a smooth transition between the gradually changing width of the straight sections and the transition sections, improving structural continuity and reducing the risk of food residue buildup during cleaning. Furthermore, widening the area near the curved sections enhances the bending resistance at the joints.

[0021] In some embodiments, the end of the handle near the dental floss holder is provided with a hand grip for the user to hold. The hand grip is flat, which improves grip comfort and controllability, and is especially suitable for long-term use.

[0022] In some embodiments, the grip portion extends from the axial direction of the handle portion towards both the upper and lower ends; and the upper and lower ends of the grip portion are arc-shaped structures to form an upper curved surface and a lower curved surface; the grip portion is formed between the upper curved surface and the lower curved surface.

[0023] The above design, with its curved upper and lower surfaces, conforms to the natural curvature of the fingers, reducing grip fatigue.

[0024] In some embodiments, the two sides of the grip portion are provided with a plurality of spaced anti-slip protrusions along the axial direction of the handle portion, which can increase friction and prevent slipping, especially suitable for wet hands and improve safety.

[0025] In some embodiments, the dimension L along the axial direction of the dental floss pick is greater than 85mm, ensuring that the entire dental floss pick is long enough to facilitate deep cleaning of the back teeth in the oral cavity, while avoiding being too short and causing inconvenience in operation.

[0046] like Figures 1-3 As shown, this utility model provides a dental floss pick, which includes a handle 100 for a user to hold; a dental floss holder 200 disposed at one end of the handle 100; the dental floss holder 200 is Y-shaped and includes a straight portion 201 and two curved portions 202, one end of each of the two curved portions 202 being joined to the same end of the straight portion 201 to form a Y-shaped dental floss holder 200; wherein, the two curved portions 202 extend and bend from the joining point toward both ends of the axis of the straight portion 201, and a transition portion 203 is provided between the straight portion 201 and the two curved portions 202; and dental floss 300 is connected between the ends of the two curved portions 202 away from the straight portion 201. By employing the above-described scheme, a stable triangular support structure is formed through the cooperation of the straight portion 201 and the two curved portions 202, enhancing the tension of the dental floss 300 and improving cleaning efficiency. The transition portion 203 avoids stress concentration, reduces the risk of floss holder 200 breakage, and extends its service life. The curved portions 202 are formed by bending outwards from both ends of the axis, expanding the coverage area of ​​the dental floss 300 and facilitating the cleaning of hard-to-reach areas such as molars. In some embodiments, the two curved portions 202 and the two transition portions 203 are formed by bending downwards along the axis of the handle portion 100, and a continuous curved surface 207 is formed at the lower end. The curved surface 207 is a three-dimensional curved surface with curvature in a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. Specifically, the first direction, the second direction, and the third direction are the X-axis, Y-axis, and Z-axis directions of the spatial rectangular coordinate system; the curved surface 207 exhibits arc-shaped changes in the X-axis, Y-axis, and Z-axis directions of the spatial rectangular coordinate system; the projection of the curved surface 207 onto the XY plane is arc-shaped, the projection onto the XZ plane is arc-shaped, and the projection onto the YZ plane is also arc-shaped, forming a three-dimensional curved surface with continuous curvature changes in three orthogonal directions.

[0047] In some embodiments, two curved portions 202 meet at the confluence of their straight portions 201, moving towards each other to form a connecting portion 204; and the connecting portion 204 and the two curved portions 202 form a U-shaped opening 205 for receiving and tensioning the dental floss 300. Using the above solution, the connecting portion 204 and the curved portions 202 form a U-shaped opening 205 to fix the dental floss 300, preventing loosening or displacement during use, and automatically maintaining the tension of the dental floss 300, thus improving cleaning effectiveness. In some embodiments, the connecting portion 204 and the two curved portions 202 extend inwardly along the inner wall of the U-shaped opening 205 to form an extension wall 206, which is U-shaped. Using the above solution, the U-shaped extension wall 206, being thinner than other portions during injection molding, is cooled and fixed first during cooling, forming a dental floss holder 200, allowing the U-shaped opening 205 to contract along both outer ends, thereby tensioning the dental floss. In some embodiments, the wall thickness of the extension wall 206 is less than the wall thickness of the connecting portion 204 and the two curved portions 202. With this design, the wall thickness of the extension wall 206 is less than the wall thickness of its outer portion, which effectively controls the shrinkage and deformation of the floss holder 200 and tightens the floss 300. In some embodiments, the width of the straight portion 201 gradually increases towards the curved portion 202, so that the two side walls of the straight portion 201 form arc-shaped walls 2011 that respectively connect with the two transition portions 203. With this design, the gradual width change of the straight portion 201 smoothly connects with the transition portion 203, improving structural continuity and reducing the risk of food residue retention during cleaning; furthermore, widening the area near the curved portion 202 enhances the bending resistance of the connection.

[0048] In some embodiments, the handle portion 100 near the dental floss holder 200 is provided with a grip portion 101 for user use. The grip portion 101 is flat, improving grip comfort and control, and is especially suitable for prolonged use. In some embodiments, the grip portion 101 extends from the axial direction of the handle portion 100 towards both the upper and lower ends; and the upper and lower ends of the grip portion 101 are arc-shaped structures to form an upper curved surface 1011 and a lower curved surface 1012; the grip portion 101 is formed between the upper curved surface 1011 and the lower curved surface 1012. With the above design, the arc-shaped structure of the upper curved surface 1011 and the lower curved surface 1012 conforms to the natural curvature of the fingers, reducing grip fatigue. In some embodiments, both sides of the grip portion 101 are provided with multiple spaced anti-slip protrusions 1013 along the axial direction of the handle portion 100, which can increase friction and prevent slippage, especially suitable for wet hands, improving safety. In some embodiments, the dimension L along the axial direction of the dental floss pick is greater than 85mm, ensuring that the entire dental floss pick is long enough to facilitate deep cleaning of the back teeth in the oral cavity, while avoiding being too short and causing inconvenience in operation.

[0049] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0050] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
