Description

Technical Field

[0001] The present invention relates to the field of dental floss picks, and more particularly to a rotatable slot-type dental floss bow. Background Art

[0002] There are two main types of dental floss picks on the market: Conventional dental floss stick (type a): with a hook at the tail and a structure where the dental floss is fixed by injection molding and sintering at the head. Figure 1 As shown, the floss is naturally loose. When cleaning the back molar area, the limited angle of the floss and the difficulty in applying force often require users to contort their face dramatically to complete the cleaning, resulting in a poor cleaning experience. Furthermore, due to the looseness of the floss, the cleaning effect is limited, and many users simply use it as a toothpick, failing to fully utilize the floss to remove plaque and interdental debris.

[0003] Removable dental floss stick (type b): With a handle-tightening design, the dental floss can be replaced independently, which increases the tightness of the dental floss and improves the cleaning effect. Figure 2 However, when cleaning the front teeth area, users often give up cleaning this area due to the inconvenience of applying force with the elbow, resulting in an incomplete user experience.

[0004] In summary, existing dental floss picks all have significant drawbacks: Type A has a simple structure but rudimentary functionality, resulting in poor cleaning effectiveness; while Type B improves tension, it sacrifices convenience for cleaning front teeth. Therefore, a dental floss pick solution is urgently needed that can provide stable tension, adapt to varying interdental angles, and achieve comfortable full-mouth cleaning. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a rotatable slot-type dental floss bow.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Example 1 See also Figure 3 The rotatable slot-type dental floss bow comprises a dental floss bow 1 and a handle 5. The handle 5 is rotatably connected to a connector 6, on which a rotating shaft 2 is mounted. The rotating shaft 2 is provided with a slot structure 3, to which the dental floss bow 1 is detachably attached. The handle 5 has a built-in drive motor, which is connected to the slot structure 3 via the rotating shaft 2 to drive the dental floss bow 1 to rotate.

[0022] In this embodiment, the rotating shaft 5 and other components are integrally rotatably mounted on the driving motor of the handle 5 through the connecting member 6, so that the rotating shaft 2, the slot structure 3 and the dental floss bow 1 can be rotated as a whole, thereby realizing multi-angle adjustment of the dental floss bow 1. The user does not need to significantly turn his wrist or deform his face exaggeratedly to adapt the dental floss to different tooth gap angles, thereby solving the problem of facial distortion or difficulty in applying force with the hand caused by the limited angle of traditional dental floss sticks.

[0023] It should be noted that there are various styles of handle 5, including telescopic electric handle, swing arm electric handle or manual handle, and the actual application is selected according to needs.

[0024] Example 2 See also Figure 4 、 5 7. This embodiment is a further improvement made on the basis of Example 1. Compared with Example 1, the slot structure 3 includes an arc-shaped clamping portion 31. A first extension portion 32 and a second extension portion 33 are respectively provided on both sides of the arc-shaped clamping portion 31. The first extension portion 32, the arc-shaped clamping portion 31 and the second extension portion 33 form a U-shaped clamping portion. The dental floss bow 1 is clamped in the U-shaped clamping portion. A horizontal turning portion 34 is provided on the second extension portion 33. A mounting hole 35 is opened on the horizontal turning portion 34. The slot structure 3 is mounted on the rotating shaft 2 through the mounting hole 35.

[0025] An arcuate recess 11 adapted to the arcuate clamping portion 31 is provided on the inner side of the dental floss bow 1 . When the dental floss bow 1 is installed, the dental floss bow 1 is clamped in the U-groove of the U-shaped clamping portion and the arcuate clamping portion 31 is located in the arcuate recess 11 .

[0026] The arc-shaped clamping portion 31 , the first extending portion 32 , the second extending portion 33 and the horizontal turning portion 34 are integrally formed, and the first extending portion 32 and the second extending portion 33 are respectively located at the middle of both sides of the arc-shaped clamping portion 31 .

[0027] In this embodiment, when installing the dental floss bow 1, the dental floss bow 1 is clamped into the U-shaped clamping portion composed of the first extension portion 32, the arc-shaped clamping portion 31 and the second extension portion 33, and at the same time, the arc-shaped clamping portion 31 is clamped into the arc-shaped recessed portion 11 of the dental floss bow 1 to form a self-locking structure to prevent the dental floss bow 1 from shaking or falling off when rotating or applying force, thereby maintaining a stable connection. The arc-shaped clamping portion 31 provides tension to the dental floss bow 1 to ensure that the dental floss is always in a taut state, thereby improving the cleaning effect. In addition, the dental floss bow 1 is installed in a snap-on manner, without the need for screws or complicated fixation. The user only needs to align the arc-shaped recessed portion 11 with the U-shaped clamping portion and press to complete the installation. It is quick to replace, suitable for daily use, and in line with the concept of environmental protection (only the dental floss bow 1 is replaced, and the handle 5 is reusable). Example 3 See also Figure 3-9 This embodiment is a further improvement made on the basis of embodiment 1 or embodiment 2. Compared with embodiment 1 or embodiment 2, the rotating shaft 2 includes a rotating connecting shaft 21 and a circular stopper 22. The rotating connecting shaft 21 is provided with a middle hole 23. The rotating connecting shaft 21 is fixedly mounted on the connecting member 6 through the middle hole 23. The connecting member 6 is provided with a slot (such as Figure 10 As shown), insert the rotating connecting shaft 21 into the slot and pass it through the middle hole 23 with fasteners such as screws, and fix the rotating connecting shaft 21 on the connector 6, so that the rotating shaft 2 as a whole can rotate together with the connector 6. In addition, the surface of the rotating connecting shaft 21 is provided with a cut surface to prevent the rotating connecting shaft 21 from rotating in the slot and enhance stability. The slot structure 3 is sleeved on the rotating connecting shaft 21, and the circular limit block 22 is used to axially limit the horizontal turning part 34 of the slot structure 3. The rotating connecting shaft 21 serves as the core transmission component and realizes power connection with the connector 6 through the middle hole 23. The circular limit block 22 is integrated with the rotating connecting shaft 21 to form an axial positioning reference surface.

[0028] A sleeve 4 is provided on the rotating connecting shaft 21 . The sleeve 4 is located between the circular limit block 22 and the horizontal turning portion 34 , and is used to increase the rotation damping to prevent the rotating shaft 2 from being too smooth.

[0029] Specifically, the sleeve 4 includes a cylindrical body 41 and a square stopper 42. The inner diameter of the cylindrical body 41 matches the diameter of the rotary connecting shaft 21, and the outer diameter matches the mounting hole 35. The square stopper 42 has a hole in the middle that communicates with the cylindrical body 41. When the sleeve 4 is installed, the cylindrical body 41 is embedded in the mounting hole 35, and the square stopper 42 is sandwiched between the horizontal turning portion 34 and the circular stopper 22.

[0030] The sleeve 4 adopts a composite structure, and the cylindrical barrel 41 precisely matches the rotating connecting shaft 21 and the mounting hole 35. The cylindrical barrel 41 precisely matches the mounting hole 35 to eliminate radial clearance. The square limit block 42 is non-rotationally symmetrically designed to prevent the sleeve 4 from rotating. The planar contact between the two sides and the horizontal turning part 34 and the circular limit block 22 increases the friction torque.

[0031] Further, such as Figure 9 As shown, the outer side of the cylindrical body 41 is provided with an integrally formed protrusion 411. The inner wall of the mounting hole 35 is provided with a recessed groove 351 that mates with the protrusion 411. The cooperation between the protrusion 411 and the recessed groove 351 eliminates circumferential play of the sleeve 4 within the mounting hole 35, ensuring the coaxiality of the rotating shaft 2. The asymmetric structure locks the relative position of the sleeve 4 and the mounting hole 35, preventing rotation of the sleeve 4 due to insufficient friction.

[0032] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
