Description

Technical Field

[0001] This invention relates to the field of oral hygiene technology, and in particular to a dental floss replacement system for electric dental floss picks. Background Technology

[0002] Physical dental floss mainly includes dental floss, manual floss picks, and electric floss picks. Dental floss requires a higher level of skill and is inconvenient for ordinary users; manual floss picks are mostly disposable, leading to significant resource waste; electric floss picks offer advantages such as high efficiency, ease of use, and reusability. Currently, most electric floss picks on the market use sonic vibrations. These products transmit motor vibrations to the flosser body and cause strong vibrations to the entire floss tip in the mouth. This can cause the floss tip to hit teeth or gums during use, potentially causing oral damage. The high-frequency sonic vibrations transmitted to the lips also negatively impact the oral cleaning experience. Furthermore, existing electric floss picks also have major drawbacks, including the inconvenience of changing floss and perceived lack of hygiene. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a dental floss replacement system for electric dental floss picks, which can simplify the dental floss replacement process after each flossing session by means of the elastic restoring force of the curved arm body, reduce the cost of each flossing session, and improve the user's oral hygiene experience.

[0004] To solve the above-mentioned technical problems, the present invention provides a dental floss replacement system for electric dental floss picks, characterized in that it includes:

[0005] fuselage casing;

[0006] The floss storage box is located inside the housing to supply dental floss;

[0007] The wire pull arm includes a bendable arm body that can be reset and bent. The two ends of the bendable arm body along its own extension direction are a fixed end and a cantilever end, respectively. The fixed end is located on the body housing, and the cantilever end is provided with a wire pulling module for clamping or releasing the dental wire drawn out from the wire storage box.

[0008] The wire clamping module is located in the housing of the machine body. The wire clamping module is located between the wire pulling module and the wire storage box to clamp the dental wire in a taut state.

[0009] The wire breaking mechanism is located on the main body of the bending arm and near the wire drawing module.

[0010] Preferably, the bending arm body includes a fixed arm disposed on the fuselage housing, a swing arm disposed on the fixed arm with a limiting swing, and a swing reset member disposed between the fixed arm and the swing arm.

[0011] Preferably, the swinging reset component is a reset torsion spring, which includes a torsion spring body and a first torsion spring support leg and a second torsion spring support leg extending from the torsion spring body. The fixed arm is provided with a first groove for the first torsion spring support leg to be engaged, and the swing arm is provided with a second groove for the second torsion spring support leg to be engaged.

[0012] Preferably, the cantilever end is provided with a threading hole, and the threading module includes a dental floss control component. The dental floss control component is provided with a thread-passing hole. When an external force is applied to the dental floss control component, the thread-passing hole and the threading hole form a mutually switching misaligned clamping relationship and an aligned thread-laying relationship.

[0013] Preferably, the dental floss control component includes a plate portion made of elastic material and a button portion disposed on the plate portion, and the floss passage is disposed on the plate portion; the bending arm body is provided with a movable cavity that allows the plate portion to elastically deform and a clearance opening that allows the button portion to protrude from the bending arm body.

[0014] Preferably, a portion of the curved arm body is composed of a split-opening main body shell and a cover, the main body shell and the cover together defining the movable cavity.

[0015] Preferably, the wire drawing module further includes a switch reset component, which is disposed between the dental floss control component and the bending arm body.

[0016] Preferably, the dental floss control component is provided with a blind mounting hole; the flossing module further includes a limiting pin disposed on the bending arm body and aligned with the blind mounting hole, and one end of the switch reset component along its own compression direction is disposed in the blind mounting hole and the other end is disposed in the limiting pin.

[0017] Preferably, the wire cutting mechanism includes a wire cutter located at the cantilever end, with the blade of the wire cutter only protruding from the wire hole.

[0018] Preferably, the housing has a stepped structure on one side along its length. The stepped structure includes a first right-angled wall and a second right-angled wall that are vertically connected. The first right-angled wall has a cable outlet hole aligned with the cable storage box, and the second right-angled wall has a through hole that allows the cable clamping module to extend.

[0019] As described above, the floss replacement system of the electric floss pick of the present invention has the following beneficial effects: the floss pull arm includes a bendable body that can be returned to its original shape when the user applies external force, and returns to its original shape when the user removes the external force. When it is necessary to replace the floss, in the first step, the cantilever end of the bendable body can be bent toward the supply side of the floss storage box, and then the pull module can release the old floss; or the cantilever end of the bendable body can be bent toward the supply side of the floss storage box, and at the same time the pull module can release the old floss. For example, when the user presses the pull module, the pull module can release the old floss, and the bendable body deforms due to the indirect force. In the second step, after ensuring that the pull module can hold the new floss, the user removes the force applied to the pull module, the pull module immediately holds the new floss, and at the same time, the bendable body returns to its original shape, so that the floss in the floss storage box is pulled out by the elastic force of the bendable body. Thirdly, since the floss between the floss-holding module and the floss storage box is taut at this point, the user clamps the taut floss with the floss-holding module. Because the floss-cutting mechanism is located on the curved arm body near the floss-holding module, the user cuts and discards the floss released from the floss-holding module using the floss-cutting mechanism. Therefore, the floss replacement system of this invention simplifies the floss replacement process after each flossing session by utilizing the elastic restoring force of the curved arm body, reducing the cost of each flossing session and improving the user's oral hygiene experience.

[0065] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0066] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance.

[0067] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, the present invention provides a dental floss replacement system for electric dental floss picks, characterized in that it includes:

[0068] fuselage housing 1;

[0069] The cable storage box 2 is located inside the housing 1 to supply dental floss 3;

[0070] The wire drawing arm 4 includes a bendable arm body 41 that can be reset and bent. The two ends of the bendable arm body 41 along its own extension direction are a fixed end 411 and a cantilever end 412, respectively. The fixed end 411 is located on the housing 1, and the cantilever end 412 is provided with a wire pulling module 42 for clamping or releasing the dental floss 3 led out from the wire storage box 2.

[0071] The wire clamping module 5 is located on the housing 1 and is positioned between the wire pulling module 42 and the wire storage box 2 to clamp the tensioned dental wire 3.

[0072] The wire breaking mechanism 6 is located on the bending arm body 41 and near the wire drawing module 42.

[0073] In this invention, the draw arm 4 includes a returnable bending arm body 41. The bending arm body 41 bends when the user applies external force and returns to its original shape when the user removes the external force. When it is necessary to replace the dental floss 3, the first step is to bend the cantilever end 412 of the bending arm body 41 toward the supply side of the floss storage box 2, and then release the old dental floss 3 using the drawer module 42; or the cantilever end 412 of the bending arm body 41 bends toward the supply side of the floss storage box 2, while the drawer module 42 releases the old dental floss 3. For example, when the user presses the drawer module 42, the drawer module 42 can release the old dental floss 3, and the bending arm body 41 deforms due to the indirect force. The second step involves the user releasing the force applied to the thread-holding module 42 after ensuring that the thread-holding module 42 can hold the new dental floss 3. The thread-holding module 42 immediately holds the new dental floss 3, and at the same time, the bending arm body 41 returns to its original shape. Thus, the dental floss 3 in the storage box 2 is extracted by the elastic force of the bending arm body 41. The third step involves the user using the clamping module 5 to hold the taut dental floss 3, since the dental floss 3 between the thread-holding module 42 and the storage box 2 is taut at this time. The user then uses the cutting mechanism 6 to cut and discard the dental floss 3 released by the thread-holding module 42, as the cutting mechanism 6 is located on the bending arm body 41 and near the thread-holding module 42.

[0074] Therefore, the floss replacement system of the electric floss pick of the present invention can simplify the floss replacement process after each flossing session by utilizing the elastic restoring force of the curved arm body 41, reducing the cost of each flossing session and improving the user's oral hygiene experience. The curved arm body 41 can be integrally formed (not shown) or assembled from multiple parts. As one embodiment of the curved arm body 41: Figure 3 As shown, to facilitate the installation of the lead-wire module 42 on the bending arm body 41 and to change the elastic restoring force of the bending arm body 41, the bending arm body 41 includes a fixed arm 413 disposed on the fuselage housing 1, a swing arm 414 disposed on the fixed arm 413 with a limiting swing, and a swing reset member disposed between the fixed arm 413 and the swing arm 414. The elastic coefficient of the swing reset member can be selected and replaced according to requirements.

[0075] like Figure 3 and Figure 5As shown, in order to improve the overall aesthetics of the curved arm body 41 and to prevent the swinging reset component from scratching the user's mouth or hands, the swinging reset component is a reset torsion spring 415. The reset torsion spring 415 includes a torsion spring body 415a and a first torsion spring support leg 415b and a second torsion spring support leg 415c extending from the torsion spring body 415a. The fixed arm 413 is provided with a first groove 413a for the first torsion spring support leg 415b to be inserted, and the swing arm 414 is provided with a second groove 414a for the second torsion spring support leg 415c to be inserted.

[0076] To simplify the structure of the aforementioned lead-in module 42, as follows: Figure 4 , Figure 6 , Figure 7 as well as Figure 8 As shown, the cantilever end 412 is provided with a threading hole 416, and the floss control module 42 includes a floss control component 421. The floss control component 421 is provided with a thread guide hole 422. When an external force is applied to the floss control component 421, the thread guide hole 422 and the threading hole 416 form a mutually switching misaligned clamping relationship and an aligned releasing relationship. That is, when the thread guide hole 422 and the threading hole 416 are misaligned, the floss control module 42 can clamp the floss 3; when the thread guide hole 422 and the threading hole 416 are aligned, the floss control module 42 can release the floss 3, so that the user can easily pull out the old floss 3.

[0077] To facilitate switching from the aligned threading relationship to the misaligned thread clamping relationship, the dental floss control component 421 includes a plate portion 421a made of elastic material and a button portion 421b disposed on the plate portion 421a. The thread guide hole 422 is disposed on the plate portion 421a. The curved arm body 41 has a movable cavity 417 that allows the plate portion 421a to elastically deform and a clearance opening 418 that allows the button portion 421b to protrude from the curved arm body 41. When the user presses or moves the button portion 421b, the plate portion 421a undergoes elastic deformation, at which time the thread guide hole 422 and the thread hole 416 are aligned with each other. When the user removes the force, the plate portion 421a returns to its original shape, at which time the thread guide hole 422 and the thread hole 416 are misaligned with each other.

[0078] To facilitate the assembly of the aforementioned lead-wire module 42 into the curved arm body 41, a portion of the curved arm body 41 is composed of a semi-open main shell 414b and a cover 414c, which together define the aforementioned movable cavity 417. Specifically, the swing arm 414 of the curved arm body 41 is composed of a semi-open main shell 414b and a cover 414c.

[0079] To ensure that the dental floss control component 421 is reset, the floss module 42 also includes a switch reset component 425, which is located between the dental floss control component 421 and the bending arm body 41.

[0080] Furthermore, to prevent the switch reset member 425 from shifting, the dental floss control member 421 is provided with a mounting blind hole 423; the lead-in module 42 also includes a limiting pin 424 disposed on the bending arm body 41 and aligned with the mounting blind hole 423, with one end of the switch reset member 425 along its own compression direction disposed in the mounting blind hole 423 and the other end disposed in the limiting pin 424. For example, the switch reset member 425 can be a compression spring.

[0081] like Figure 7 As shown, to simplify the structure of the wire cutting mechanism 6, the wire cutting mechanism 6 includes a wire cutter 61 located at the cantilever end 412, with the blade of the wire cutter 61 only protruding from the wire hole 416. Furthermore, the fact that the blade of the wire cutter 61 only protrudes from the wire hole 416 protects the user.

[0082] To improve the structural compactness of the dental floss replacement system, the housing 1 has a stepped structure 11 on one side along its length. The stepped structure 11 includes a first right-angled wall 111 and a second right-angled wall 112 connected vertically. The first right-angled wall 111 has a wire outlet hole 12 aligned with the wire storage box 2, and the second right-angled wall 112 has a through hole 13 that allows the wire clamping module 5 to extend.

[0083] In summary, the floss replacement system of the electric floss pick of this invention simplifies the floss replacement process after each flossing session by utilizing the elastic restoring force of the curved arm, reducing the cost of each flossing session and improving the user's oral hygiene experience. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0084] 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.
