[0025] To illustrate the technical solutions provided by the present disclosure, detailed descriptions are provided below in conjunction with specific figures and embodiments.

[0026] An embodiment of the present disclosure provides a dental floss device that includes a case 20, a floss supply box 10, and a driver 30. The floss supply box 10 and the driver 30 are both attached to the case 20.

[0027] As shown in Figs. 1 to 5, the case 20 has a storage chamber 23. The floss supply box 10 includes a box body 11, a floss supply assembly 12, and a dental floss holder 13. The box body 11 is provided in the storage chamber 23, and the floss supply assembly 12 is attached to the box body 11. The floss supply assembly 12 can collect used dental floss 123 and release unused dental floss 123 by driving the driving device 30. The dental floss holder 13 has one end connected to the floss supply assembly 12 and the other end extending outside the case 20. The dental floss holder 13 spreads the floss 123 released from the floss supply assembly 12, thereby spreading the floss 123 at the other end of the dental floss holder 13. The driving device 30 drives the floss supply assembly 12 to cause the floss supply assembly 12 to collect and release the dental floss 123.

[0028] In actual use, the driving device 30 first drives the floss supplying assembly 12 to release the first dental floss 123, and the first dental floss 123 is spread by the dental floss holder 13 so that the dental floss 123 can be used to clean the teeth. After the cleaning is completed, the driving device 30 drives the floss supplying assembly 12 to collect the used dental floss 123 and release new dental floss 123. Thus, when the floss 123 of the floss supplying assembly 12 is used up, the entire floss supplying box 10 can be removed from the case 20 and a new floss supplying box 10 can be replaced.

[0029] In addition, the box body 11, floss supply assembly 12, and dental floss holder 13 in the floss supply box 10 of the present disclosure may all be manufactured from degradable or recycled materials, i.e., they do not pollute the environment even when the floss supply box 10 is removed and replaced.

[0030] The dental floss device of the present disclosure can be used multiple times in succession by installing the floss supply assembly 12. In addition, after the floss supply box 10 is used up, it can be replaced with a new floss supply box 10 and used continuously, which not only reduces costs but also avoids the problem of environmental pollution caused by the disposal of the dental floss device. In addition, the box 11, the floss supply assembly 12, and the dental floss holder 13 are all made of degradable or recycled materials, and the environment is not polluted even when the floss supply box 10 is removed and replaced, so that the dental floss device of the present disclosure is an environmentally friendly product. In addition, the box 11 integrates the floss supply assembly 12 and the dental floss holder 13 as a whole, so that the floss supply assembly 12 and the dental floss holder 13 can be assembled as a whole, and can be replaced as a whole when necessary. In addition, the distance from the floss supply assembly 12 to the dental floss holder 13 is reduced, and there is no need to install a connecting dental floss holder between the floss supply assembly 12 and the dental floss holder 13 to pass the dental floss 123 through, making the structure of the entire dental floss device simpler and more convenient to assemble. Furthermore, when performing subsequent maintenance or replacement, it is only necessary to replace the entire floss supply box 10, making it easier to use repeatedly.

[0031] In one embodiment, the housing 11 has an attachment chamber 113, and when the floss supplying assembly 12 is removably mounted in the attachment chamber 113, the floss supplying assembly 12 can be replaced by removing the floss supplying assembly 12 from the attachment chamber 113. It should be noted that in other embodiments of the present disclosure, the housing 11 may not have the attachment chamber 113, and the housing 11 and the floss supplying assembly 12 may be connected together, that is, the floss supplying assembly 12 may be installed in a disposable structure, and after use, the floss supplying assembly 12 may be replaced together with the housing 11, and this is not particularly limited here.

[0032] In one embodiment, the floss supplying assembly 12 and the dental floss holder 13 are movably mounted in the case 11, and the driving device 30 further drives the floss supplying assembly 12 and the dental floss holder 13 to perform a reciprocating linear motion in the case 11, so as to move the other end of the dental floss holder 13 out of the case 11 and back into the storage chamber 23. When not in use, the floss supplying assembly 12 and the dental floss holder 13 are both stored in the storage chamber 23. In use, the driving device 30 moves the dental floss holder 13 and the floss supplying assembly 12 as a whole in the box 11, and after the other end of the dental floss holder 13 extends to the outside of the case 20 by a predetermined length, the dental floss 123 is used to clean the teeth, and after use is completed, the driving device 30 retrieves the floss supplying assembly 12 and the dental floss holder 13 to protect the dental floss holder 13 and its dental floss 123 and prevent the dental floss 123 from being contaminated or damaged. In addition, in other embodiments of the present disclosure, the box 11 may be movably mounted in the receiving chamber 23 according to actual design conditions and specific requirements, and the driving device 30 drives the box 11, the floss supplying assembly 12 and the dental floss holder 13 to perform reciprocating linear motion in the receiving chamber 23 to move the other end of the dental floss holder 13 out of the box 11 or retract it into the receiving chamber 23. In some other embodiments, the box body 11 may be removably attached to the storage chamber 23, in which case the other end of the dental floss holder 13 always extends outside the case 20 to spread the dental floss 123, and this is not limited thereto.

[0033] In one embodiment, as shown in FIG. 2, the driving device 30 includes a slide switch 31 and a transmission mechanism 32. The slide switch 31 is slidably mounted on the case 20 and can be slid back and forth by the user to output a reciprocating linear motion. The transmission mechanism 32 is connected between the slide switch 31 and the floss supplying assembly 12, and the transmission mechanism 32 converts the reciprocating linear motion of the slide switch 31 into the reciprocating linear motion of the floss supplying assembly 12 and the unidirectional rotational motion of the floss supplying assembly 12. That is, in this embodiment, by sliding the slide switch 31, the floss supplying assembly 12 can retrieve or release the floss, and the other end of the dental floss holder 13 can extend or retract from the receiving chamber 23 through the transmission mechanism 32, which is simple to operate, and the user only needs to slide the slide switch 31 on the case 20. The simple structure of the driving device 30 simplifies the structure of the entire dental flossing device and reduces the space occupied by the device.

[0034] As shown in FIG. 2 and FIG. 7, the transmission mechanism 32 includes a first transmission member 321, a second transmission member 322, and a position restriction structure 323.

[0035] The first transmission member 321 is a rotating member, that is, the first transmission member 321 can be rotationally driven. The first transmission member 321 is rotatably connected to the output shaft of the slide switch 31. The first transmission member 321 is further connected to the floss supplying assembly 12, and can perform reciprocating linear motion by the slide switch 31. In addition, due to the characteristic that the first transmission member 321 and the output shaft are rotationally connected, when the first transmission member 321 is rotationally driven by an external force, the first transmission member 321 can rotate around the output shaft.

[0036] The second transmission member 322 is fixedly installed. The second transmission member 322 is a linear member. The second transmission member 322 extends in the direction of the reciprocating linear motion of the first transmission member 321 .

[0037] Here, the position control structure 323 abuts against the moving first transmission member 321 to control its position, thereby changing the position or posture of the first transmission member 321 so as to form a transmission connection with the second transmission member 322, thereby rotating the first transmission member 321 in one direction along the longitudinal direction of the second transmission member 322 on the second transmission member 322.

[0038] In addition, the change in the position or posture of the first transmission member 321 may be caused by the first transmission member 321 rotating on the spot to change its posture, or the first transmission member 321 moving in the axial direction to change its position. For example, there is no transmission connection between the first transmission member 321 and the second transmission member 322 before contacting the position restriction structure 323. When the first transmission member 321 is rotationally connected to the output shaft of the slide switch 31 and the linear motion of the first transmission member 321 is prevented, this corresponds to an external force being applied to the first transmission member 321, which causes the first transmission member 321 to rotate around the output shaft on the spot, changes the position of the first transmission member 321, and the first transmission member 321 and the second transmission member 322 are transmission-connected to each other, so that the first transmission member 321 can rotate in one direction in the second transmission member 322 along the longitudinal direction of the second transmission member 322.

[0039] As shown in Fig. 7 and Fig. 8, the first transmission member 321 includes a rotor 3211 and a connector 3214, the rotor 3211 is rotatably connected to the output shaft of the slide switch 31, and the connector 3214 is connected to the floss supplying assembly 12. The rotor 3211 has first teeth 3212 distributed along the circumferential direction on its outer circumferential surface. The rotor 3211 has a straight surface 3213 formed by removing material from the outer circumferential surface of the rotor 3211 at a position where the first teeth 3212 are not present. The second transmission member 322 includes a straight body 3221 and second teeth 3222, and the second teeth 3222 are linearly distributed on the straight body 3221. The rotor 3211 is stopped by the position regulating structure 323 during movement, and rotates on the spot, so that the first teeth 3212 and the straight surface 3213 are alternately arranged corresponding to the second teeth 3222. When the first tooth 3212 is installed corresponding to the second tooth 3222, the first tooth 3212 and the second tooth 3222 are connected, and when the straight surface 3213 is installed corresponding to the second tooth 3222, the first transmission member 321 maintains linear motion. In the present disclosure, the first tooth 3212 and the straight surface 3213 are distributed on the outer periphery of the rotating body 3211, and the first tooth 3212 and the straight surface 3213 are alternately installed corresponding to the second tooth 3222, thereby realizing an intermittent transmission connection between the first transmission member 321 and the second transmission member 322, that is, in the present disclosure, by changing the portion of the first transmission member 321 corresponding to the second transmission member 322, the intermittent transmission connection between the first transmission member 321 and the second transmission member 322 can be realized, and the structure is simple, and there is no need to provide an external support structure to drive the first transmission member 321 and the second transmission member 322 to realize the connection. In addition, in other embodiments of the present disclosure, according to actual design conditions, the first teeth 3212 and the straight surface 3213 may be distributed along the axial direction, and the first teeth 3212 and the straight surface 3213 may be alternately arranged corresponding to the second teeth 3222 by changing the position of the first transmission member 321 or the second transmission member 322 in the axial direction. For example, by installing an elastic member between the rotating body 3211 and the slide switch 31, when the rotating body 3211 moves to the position restriction structure 323, the position restriction structure 323 abuts against the rotating body 3211 along the axial direction, so that the axial position of the rotating body 3211 is changed, and further the positions of the first teeth 3212 and the straight surface 3213 in the axial direction are changed.

[0040] 7, the position restriction structure 323 includes a stopper 3232 and a protruding post 3231. The stopper 3232 is provided in the case 20, the stopper 3232 and the rotor 3211 are offset from each other along the axial direction of the rotor 3211, and the protruding post 3231 is provided on the rotor 3211 and protrudes from an end face of the rotor 3211 along the axial direction, i.e., the protruding post 3231 and the rotor 3211 are offset from each other along the axial direction, and the stopper 3232 and the protruding post 3231 are correspondingly provided along the axial direction of the rotor 3211. In this case, when the rotor 3211 moves to the position of the stopper 3232, the protruding post 3231 and the stopper 3232 come into contact with each other to rotate the rotor 3211. In this embodiment, there is no need to add a driving structure to change the position of the first transmission member 321 or the second transmission member 322. The rotor 3211 can be rotated only by the abutment of the stopper 3232 with the protruding post 3231 and the driving of the driving device 30, thereby converting the state between the first transmission member 321 and the second transmission member 322 from a non-connected state to a transmission connected state, which results in a simple structure, simple assembly, and simple manufacturing process.

[0041] As shown in FIG. 2 and FIG. 8, the slide switch 31 includes a first slide button 311 and a connection member 312. The first slide button 311 is slidably provided on the surface of the case 20. The connection member 312 includes a connection portion 3121 and a rotating shaft portion 3122 that are connected to each other. The connection portion 3121 is connected to the first slide button 311. The rotating body 3211 is rotatably provided around the rotating shaft portion 3122. When the first slide button 311 is slid on the surface of the case 20, the connection portion 3121 and the rotating shaft portion 3122 cause the first transmission member 321 to perform a reciprocating linear motion, and the second transmission member 322 and the position restriction structure 323 cooperate to finally output the reciprocating linear motion of the floss supplying assembly 12 and the unidirectional rotational motion of the first transmission member 321.

[0042] 2, in one embodiment, the connection part 3121 is integrally connected to the first sliding button 311, i.e., the connection member 312 is integrally connected to the first sliding button 311, and by installing in this manner, the connection member 312 and the first sliding button 311 can be processed and molded together, which simplifies the manufacturing process and assembly process of the connection member 312 and the first sliding button 311. Note that, in other embodiments of the present disclosure, the connection part 3121 and the first sliding button 311 may be connected separately, i.e., the connection member 312 and the first sliding button 311 may be manufactured separately and then fixed, and there is no particular limitation here.

[0043] 5 and 6, the floss supply assembly 12 includes a first floss shaft 121, a second floss shaft 122, and a dental floss 123. The first floss shaft 121 is rotatably mounted on the housing 11, the second floss shaft 122 is rotatably mounted on the housing 11, and the dental floss 123 passes through the dental floss holder 13. One end of the dental floss 123 is wound around the first floss shaft 121, and the other end is wound around the second floss shaft 122. When mounting, the first floss shaft 121 is connected to the connector 3214, the unused dental floss 123 is wound around the first floss shaft 121, and the used dental floss 123 is wound around the second floss shaft 122. After the dental floss 123 is used, the first slide button 311 is slid to rotate the first floss shaft 121 via the connecting member 312, the rotating body 3211, and the connecting body 3214, thereby releasing the unused dental floss 123. In the present disclosure, the design of the first floss shaft 121 and the second floss shaft 122 can sufficiently separate the unused dental floss 123 from the used dental floss 123, preventing the used dental floss 123 from contaminating the unused dental floss 123. It should be noted that in other embodiments of the present disclosure, the floss supply assembly 12 may include only one floss shaft according to the actual design requirements. In this case, the unused dental floss 123 and the used dental floss 123 are wound around the opposite ends of the floss shaft, respectively, and the unused dental floss 123 is separated from the used dental floss 123 by a partition plate, which is not particularly limited here.

[0044] In one embodiment, as shown in Figures 5 and 6, the first floss shaft 121 and the second floss shaft 122 are installed coaxially, and the dental floss 123 on the first floss shaft 121 and the dental floss 123 on the second floss shaft 122 are installed at a distance along the axial direction of the first floss shaft 121. The dental floss holder 13 is located on the same side as the first floss shaft 121 and the second floss shaft 122 in the axial direction perpendicular to the first floss shaft 121, so that the dental floss 123 on the first floss shaft 121 can be easily inserted into the dental floss holder 13, and the dental floss 123 on the dental floss holder 13 can be easily wound around the second floss shaft 122. In addition, the overall structure of the first floss shaft 121, the second floss shaft 122, and the dental floss holder 13 can be made compact, and the space occupied by the dental floss holder 13 can be reduced. Furthermore, the overall space occupied by the floss supply box 10 is reduced, making the structure of the dental floss device compact and easy to carry.

[0045] As shown in Fig. 8, the first floss shaft 121 has a mounting hole 1211 at its center, and a plurality of first position restriction ribs 1212 are provided on the inner wall of the mounting hole 1211 and distributed along the circumferential direction. The first position restriction ribs 1212 extend along the axial direction of the mounting hole 1211, and a slot 1213 is formed between two adjacent first position restriction ribs 1212. A plurality of second position restriction ribs 3215 are provided on the outer wall of the connecting body 3214, and the plurality of second position restriction ribs 3215 are inserted into different slots 1213, and when the connecting body 3214 is inserted into the mounting hole 1211, the second position restriction ribs 3215 are inserted and fitted into the slots 1213, thereby realizing the circumferential position restriction of the first floss shaft 121 and the connecting body 3214. In this case, when the connecting body 3214 rotates, the first floss shaft 121 is rotated, and the dental floss is released and collected. It should be noted that in other embodiments of the present disclosure, the first floss shaft 121 may be connected to the connector 3214 by a key connection, an interference fit connection, or a screw lock connection, which are not particularly limited herein.

[0046] When the number of the slots 1213 is greater than the number of the second position restricting ribs 3215, the second position restricting ribs 3215 can be inserted into different slots 1213 for ease of assembly.

[0047] In one embodiment, as shown in FIG. 2 and FIG. 4, the case 20 includes a base 21 and a top cover 22, and the base 21 and the top cover 22 surround and form a storage chamber 23, in which the box 11, the floss supply assembly 12, and the dental floss holder 13 are all stored. A guide holder 24 is provided on the inside of the top cover 22, and a first slide button 311 is slidably provided on the guide holder 24. A through groove is provided on the top cover 22 at a position corresponding to the first slide button 311. The first slide button 311 is exposed to the outside through the through groove so that it can be slid by a user. In the present disclosure, the guide holder 24 is provided to guide and regulate the position of the first slide button 311 with respect to sliding.

[0048] In one embodiment, as shown in Figs. 2 and 4, one end of the top cover 22 is rotatably mounted on one end of the base 21, and an elastic member 25 is in contact between one end of the top cover 22 and one end of the base 21. The other end of the top cover 22 can be separated from the other end of the base 21 after one end of the top cover 22 is pressed. Specifically, the elastic member 25 is a compression spring mounted in the receiving chamber 23, and the bottom end is fixedly connected to the inner wall of one end of the base 21, and the top end is fixedly connected to the inner wall of one end of the top cover 22. When the top cover 22 and the base 21 cover each other, the elastic member 25 is in a natural state, and when one end of the top cover 22 is pressed, the top cover 22 rotates around its one end until the other end of the top cover 22 is separated from the other end of the base 21, making it easy to take out the floss supply box 10. In addition, the elastic member 25 is in a compressed state at this time and accumulates elasticity. When the external force on one end of the top cover 22 is removed, the one end of the top cover 22 moves upward due to the elasticity of the elastic member 25, causing the top cover 22 to rotate in the reverse direction until it is covered by the base 21. Due to the above-mentioned structural design, the case 20 of this embodiment allows the user to quickly and easily open the top cover 22 and take out the floss supply box 10.

[0049] 2, the base 21 is provided with two rotating shafts 211 that are coaxial and extend in opposite directions, and the inner wall of the top cover 22 is provided with shaft holes distributed in accordance with the positions of the two rotating shafts 211. When mounting, the two rotating shafts 211 are inserted into the two shaft holes, respectively, to realize a rotational connection of the top cover 22 to the base 21.

[0050] In one embodiment, as shown in Fig. 5, the dental floss holder 13 includes two floss tubes 131 and a mounting member 132, the two floss tubes 131 are spaced apart from each other, and the floss tubes 131 have floss holes 1311. The floss holes 1311 pass through both ends of the floss tube 131 along the longitudinal direction and are used to pass the dental floss 123 through. The mounting member 132 is connected between one ends of the two floss tubes 131, and both one ends of the two floss tubes 131 and the mounting member 132 are housed in the box 11, and the other ends of the two floss tubes 131 extend outside the box 11. The mounting member 132 is provided with a mounting structure, which is used for removably connecting to the floss supply assembly 12. In the present disclosure, one end of two floss tubes 131 is fixedly connected to each other by the mounting member 132, and a mounting structure is provided on the mounting member 132, so that the mounting member 132 and the floss supplying assembly 12 can be detachably connected, which makes it easy to attach and detach the dental floss holder 13, and facilitates subsequent maintenance and replacement. In addition, by arranging the floss holes 1311 to penetrate both opposing ends of the floss tube 131, the dental floss 123 is entirely protected by the floss holes 1311 except for the part for cleaning the teeth, so that the dental floss 123 is clean, sanitary, and less susceptible to dust before use, and damage before use is suppressed to ensure the function of the dental floss 123. Note that in other embodiments of the present disclosure, the mounting member 132 may be integrally connected to the floss supplying assembly 12. Specifically, the floss supplying assembly 12 further includes a mounting base 14, and the first floss shaft 121 and the second floss shaft 122 are both mounted in the inner chamber of the mounting base 14. The mounting member 132 is integrally connected to the mounting base 14 to make the connection between the floss supplying assembly 12 and the dental floss holder 13 stronger.

[0051] As shown in FIG. 5, the box body 11 includes a box base 111 and a box lid 112. The edge of the box base 111 and the edge of the box lid 112 engage with each other to form an attachment chamber 113 therearound.

[0052] In some other embodiments of the present disclosure, the driving device 30 may include a second slide button and a driving motor. The second slide button is connected to the dental floss holder 13. The second slide button slides to cause the floss supplying assembly 12 and the dental floss holder 13 to perform a reciprocating linear motion within the receiving chamber 23. The driving motor is connected to the floss supplying assembly 12 and drives the floss supplying assembly 12 to rotate in one direction to retrieve or release the floss. That is, the two driving structures of the second slide button and the driving motor drive the reciprocating linear motion of the dental floss holder 13 and the retrieval or release of the floss by the floss supplying assembly 12, respectively.

[0053] The above is merely an embodiment of the present disclosure, and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure can be modified and changed in various ways. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure should be included within the scope of the claims of the present disclosure.
