[0016] Preferably, the floss rotation system of the electric floss pick further includes a transmission gear assembly, which includes a driving gear and a driven gear that mesh with each other. The driving gear is located on the rotating transmission shaft, and the driven gear is rotatably mounted on the housing and meshes with the torsion wheel assembly.

[0017] Preferably, the rotary drive shaft has a polygonal cross-section, and the drive gear has a mounting through hole that allows the rotary drive shaft to pass through, the mounting through hole having a polygonal cross-section.

[0054] like Figure 1 and Figure 4 As shown, the present invention provides a dental floss rotation system for an electric dental floss pick, comprising:

[0055] fuselage housing 1;

[0056] Movement module 2, movement module 2 is disposed on the body housing 1;

[0057] Rotary drive shaft 3 is rotatably mounted on the housing 1 and is connected to the core module 2.

[0058] Torsion wheel assembly 4 is rotatably mounted on the machine body housing 1 and is connected to the rotary transmission shaft 3.

[0059] Dental floss module 5 includes dental floss segment 51. The two ends of dental floss segment 51 are respectively disposed on different parts of the torsion wheel assembly 4, or one end of dental floss segment 51 is disposed on the torsion wheel assembly 4 and the other end is disposed on the body housing 1. Dental floss segment 51 is in a taut state.

[0060] The aforementioned dental wire segment 51 achieves fixed-axis rotation and / or fixed-axis twisting under the drive of the torsion wheel assembly 4.

[0061] In this invention, the movement module 2 is disposed on the body housing 1, and the rotary drive shaft 3 is rotatably disposed on the body housing 1. The rotary drive shaft 3 is drive-connected to the movement module 2, so that the movement module 2 can provide kinetic energy to the rotary drive shaft 3. The torsion wheel assembly 4 is drive-connected to the rotary drive shaft 3, so that the torsion wheel assembly 4 rotates under the drive of the rotary drive shaft 3. More importantly, the two ends of the floss segment 51 of the floss module 5 are respectively located on different parts of the torsion wheel assembly 4, or one end of the floss segment 51 is located on the torsion wheel assembly 4 and the other end is located on the body housing 1, and the floss segment 51 is in a taut state. In this way, when the core module 2 is running, the floss segment 51 is driven by the torsion wheel assembly 4 to achieve fixed-axis rotation and / or fixed-axis twisting, so that the floss segment 51 can more easily slide into the gaps between teeth and wipe the sidewalls of the teeth in the form of fixed-axis rotation and / or fixed-axis twisting motion, improving the degree of cleaning, avoiding vibration of the entire body housing 1 of the electric floss pick, and not impacting the teeth or gums. Only the floss module 5 needs to be replaced, greatly reducing the amount of material consumed each time you pick your teeth.

[0062] Therefore, the floss rotation system of the electric floss pick of the present invention enables the floss segment 51 to enter the interdental space in a motion of fixed-axis rotation and / or fixed-axis twisting, wipe the sidewalls of the teeth, improve the degree of cleaning, avoid discomfort in the oral cavity caused by vibration of the entire body shell 1 of the electric floss pick, and greatly reduce the amount of material consumed each time.

[0063] Various embodiments of the connection method of the above-mentioned dental floss segment 51 are as follows:

[0064] First embodiment (not shown): One end of the dental floss segment 51 is disposed on the torsion wheel assembly 4 and the other end is disposed on the housing 1. The dental floss segment 51 achieves fixed-axis rotation under the drive of the torsion wheel assembly 4.

[0065] Second embodiment (see details) Figure 4 and Figure 5 The two ends of the dental floss segment 51 are respectively located on different parts of the torsion wheel assembly 4, and all parts of the torsion wheel assembly 4 rotate synchronously in the same direction of rotation. The dental floss segment 51 achieves fixed-axis rotation under the drive of the torsion wheel assembly 4.

[0066] Third embodiment (not shown): The two ends of the toothed wire segment 51 are respectively disposed on different parts of the torsion wheel assembly 4. All parts of the torsion wheel assembly 4 rotate in the same direction of rotation, and the different parts of the torsion wheel assembly 4 have different rotation speeds. The toothed wire segment 51 achieves both fixed-axis twisting and fixed-axis rotation under the drive of the torsion wheel assembly 4.

[0067] Fourth embodiment (not shown): The two ends of the dental floss segment 51 are respectively disposed on different parts of the torsion wheel assembly 4. The different parts of the torsion wheel assembly 4 rotate in different rotation directions, and the dental floss segment 51 achieves fixed-axis rotation under the drive of the torsion wheel assembly 4.

[0068] Several embodiments of the arrangement of the above-mentioned dental floss segment 51 are as follows:

[0069] First embodiment: Combination Figure 4 and Figure 5 The dental floss axis 511 of the dental floss segment 51 coincides with the rotation center line 41 of the torsion wheel assembly 4.

[0070] Second embodiment: The dental floss axis 511 of the dental floss segment 51 forms an angle with the rotation center line 41 of the torsion wheel assembly 4.

[0071] like Figure 4 and Figure 5 As shown, in order to make the above-mentioned dental floss segment 51 taut, the above-mentioned torsion wheel assembly 4 includes two dental floss torsion wheels 42 that are spaced apart and opposite to each other. The two dental floss torsion wheels 42 are respectively connected to the rotating transmission shaft 3. One end of the above-mentioned dental floss segment 51 is detachably connected to one of the dental floss torsion wheels 42 and the other end is detachably connected to the other dental floss torsion wheel 42.

[0072] like Figure 4 and Figure 6 As shown, in order to facilitate the replacement of the dental floss module 5 each time teeth are flossed, the dental floss segment 51 is provided with a locking piece 52 at both ends. The dental floss torsion wheel 42 includes a torsion wheel body 421 and a locking groove 422 provided on the end face of the torsion wheel body 421. The locking groove 422 is engaged with the locking piece 52.

[0073] In order to make the dental floss segment 51 extend in a straight line, the slot 422 is provided with a notch 423 to avoid the dental floss segment 51.

[0074] To facilitate user assembly and disassembly of the dental floss module 5 and the torsion wheel assembly 4, the slot 422 is open on one side, with the opening of the slot 422 facing the radial outer side of the torsion wheel body 421.

[0075] The aforementioned rotary drive shaft 3 and the torsion wheel assembly 4 can be connected by either a belt drive or a gear drive. Since gear drives are more compact and have higher transmission efficiency, the dental floss rotation system of the electric dental floss pick also includes a transmission gear assembly 6. The transmission gear assembly 6 includes a meshing drive gear 61 and a driven gear 62. The drive gear 61 is located on the rotary drive shaft 3, and the driven gear 62 is rotatably mounted on the housing 1 and meshes with the torsion wheel assembly 4. This arrangement further improves the structural compactness of the electric dental floss pick.

[0076] To ensure that the aforementioned drive gear 61 is circumferentially fixed relative to the rotary transmission shaft 3, the cross-section of the rotary transmission shaft 3 is polygonal, for example, triangular (not shown), or, for example, rectangular with chamfers (see [reference]). Figure 5 The aforementioned drive gear 61 has a mounting through hole that allows the rotating drive shaft 3 to pass through. The cross-section of the mounting through hole is polygonal, for example, triangular (not shown), or, for example, rectangular with chamfers (see [reference]). Figure 5 Furthermore, the rotary drive shaft 3 includes a large-diameter shaft segment 32 and a small-diameter shaft segment 33 connected axially, with the cross-section of the small-diameter shaft segment 33 being polygonal.

[0077] like Figure 4 and Figure 5 As shown, in order to prevent the aforementioned drive gear 6 from moving axially, the aforementioned drive gear 61 includes a drive gear part 611 and a limiting bushing part 612 that is axially connected to the drive gear part 611. The drive gear part 611 meshes with the driven gear 62, and the limiting bushing part 612 is used to constrain the position of the drive gear part 611 on the rotary transmission shaft 3.

[0078] like Figure 2 and Figure 3 As shown, to facilitate the assembly and disassembly of the rotary drive shaft 3 and the mechanism module 2, the mechanism module 2 includes a rotary drive device 21 and a power output head 22 disposed on the rotary drive device 21. One end of the rotary drive shaft 3 is provided with a mounting groove 31 that allows the power output head 22 to be inserted. Furthermore, the mounting groove 31 is formed at the end of the large-diameter shaft section 32.

[0079] Furthermore, the cross-sections of both the power output head 22 and the mounting groove 31 are polygonal. For example, their cross-sections are both chamfered triangles (see...). Figure 2 and Figure 3 For example, the cross-sections are all rectangular (not shown).

[0080] In summary, the floss rotation system of the electric floss pick of this invention enables the floss segment to enter the interdental spaces through a fixed-axis rotation and / or fixed-axis twisting motion, wiping the sidewalls of the teeth, improving the degree of floss cleaning, avoiding discomfort in the oral cavity caused by vibration of the entire body of the electric floss pick, and greatly reducing the amount of floss consumed each time. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0081] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
