Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] See also Figures 1 to 7 Now, the teeth cleaning device provided in the embodiment of the present application is described. The teeth cleaning device is used to clean human teeth, and the teeth cleaning device can be reused many times, thereby reducing costs and reducing environmental pollution.

[0046] The tooth cleaning device includes a housing 10 , a wire retracting and releasing structure 20 and a dental floss rack 30 , wherein the wire retracting and releasing structure 20 and the dental floss rack 30 are both installed on the housing 10 .

[0047] Specifically, the retractable wire structure 20 is detachably mounted on the shell 10, and the retractable wire structure 20 is used to release new dental floss 231 and recycle the used dental floss 231 after each use of the dental floss 231, and the dental floss rack 30 is used to stretch the dental floss 231 released by the retractable wire structure 20, that is, the dental floss 231 is placed on the dental floss rack 30 to reach a tensioned state, thereby achieving the purpose of cleaning teeth. During actual use, a new retractable wire structure 20 is first installed on the shell 10, and the original dental floss 231 is provided on the outside of the retractable wire structure 20. The dental floss 231 is then stretched out by the dental floss holder 30, and then the teeth are cleaned with the dental floss 231. After cleaning, the used dental floss 231 is recovered by the retractable wire structure 20, and a new dental floss 231 is released at the same time. This is repeated in sequence until the dental floss 231 of the entire retractable wire structure 20 is used up. Then the entire retractable wire structure 20 is removed from the shell 10 and replaced with a new retractable wire structure 20.

[0048] Specifically, the retractable wire structure 20 is made of environmentally friendly materials, that is, the retractable wire structure 20 will not pollute the environment and can even be recycled to reduce waste.

[0049] The teeth cleaning device of the present application can be reused and can even be used continuously for several weeks through the setting of the above-mentioned retractable wire structure 20, and can continue to be used after replacing the retractable wire structure 20, which not only saves costs but also avoids environmental pollution problems caused by discarding the teeth cleaning device.

[0050] See also Fig.10 The wire-reeling and retracting structure 20 includes a cylinder 21, a rotating shaft 22, a dental floss roll 23 and a tensioning member 241, and a driving structure 40 is also provided on the housing 10. The cylinder 21 has a storage cavity, and a wire-releasing hole 214 and a wire-retracting hole 215 are provided on the surface of the cylinder 21, and the wire-releasing hole 214 and the wire-retracting hole 215 are respectively connected to the storage cavity. The rotating shaft 22 axially penetrates the cylinder 21, and the rotating shaft 22 is connected to the driving structure 40 and can be driven by the driving structure 40 to rotate. The dental floss roll 23 is arranged in the storage cavity and sleeved on the rotating shaft 22, and the tensioning member 241 is arranged outside the cylinder 21. The dental floss 231 on the dental floss roll 23 comes out of the wire-releasing hole 214 and is wound on the tensioning member 241, and enters the storage cavity from the wire-retracting hole 215 to be wound on the rotating shaft 22. In actual work, in the initial state, one end of the dental floss 231 on the dental floss roll 23 comes out from the storage chamber through the wire release hole 214 and is wound on the tensioning member 241, and enters the storage chamber through the wire take-up hole 215, and is finally wound around the rotating shaft 22 at the lower part of the storage chamber; after the dental floss 231 is used up, the rotating shaft 22 is driven to rotate by the driving structure 40, and the rotation of the rotating shaft 22 drives the dental floss roll 23 to release a new dental floss 231 and wind it around the tensioning member 241, and the used dental floss 231 enters the storage chamber from the wire take-up hole 215 driven by the rotating shaft 22 and is wound on the lower part of the rotating shaft 22, and this is carried out in sequence until the dental floss roll 23 is completely used up, and then a new wire take-up and release structure 20 is replaced.

[0051] More specifically, a partition 211 is provided in the axial middle position of the storage chamber, and the partition 211 divides the storage chamber into a wire-release chamber 212 and a wire-receiving chamber 213; the dental floss roll 23 is provided in the wire-release chamber 212, the rotating shaft 22 passes through the wire-release chamber 212 and the wire-receiving chamber 213, the wire-release hole 214 is connected to the wire-release chamber 212, and the wire-receiving hole 215 is connected to the wire-receiving chamber 213. The present application separates the wire-release chamber 212 and the wire-receiving chamber 213 by the partition 211 to prevent bacteria from spreading in the storage chamber, that is, to separate unused dental floss from used dental floss, so that the used dental floss will not contaminate the unused dental floss, thereby making the tooth cleaning device clean and hygienic to use.

[0052] In this embodiment, the dental floss 231 is made of silk, which is environmentally friendly and recyclable. At the same time, the cylinder 21 is made of degradable plastic or metal, so when the retractable wire structure 20 needs to be replaced, the retractable wire structure 20 will not cause pollution to the environment even if it is discarded, and the retractable wire structure 20 can also be recycled.

[0053] See also Figures 7 to 10 The retractable wire structure 20 further includes a bottom plate 24, which is in the shape of a thin plate and is installed on the bottom side of the cylinder 21. The bottom plate 24 extends from the bottom side of the cylinder 21 along the extension direction of the dental floss rod 31. The tensioning member 241 is a vertical block erected on one end of the bottom plate 24 away from the cylinder 21. A groove 2411 is provided on the side of the vertical block away from the cylinder 21. The height of the groove 2411 is the same as the height of the upper surface of the cylinder 21. The dental floss 231 outside the cylinder 21 is hung on the groove 2411, thereby forming a V-shape parallel to the upper surface of the cylinder 21. The tensioning member 241 is fixed to the outside of the cylinder 21 through the bottom plate 24, so that the dental floss 231 extending outside the cylinder 21 can be stretched by the tensioning member 241.

[0054] The driving structure 40 is used to drive the rotating shaft 22 to rotate. The driving structure 40 can be driven to rotate by a manual knob or by a slide button 41. The present application is driven by the slide button 41, and its specific driving method will be described later.

[0055] See also Figure 7 The housing 10 has an installation cavity 13 and a wire outlet 14 . The installation cavity 13 is formed inside the housing 10 . The wire outlet 14 is formed on the surface of the housing 10 . The wire outlet 14 and the installation cavity 13 are connected to each other.

[0056] The driving structure 40 is also connected to the dental floss holder 30, and the driving structure 40 is used to drive the dental floss holder 30 so that the dental floss holder 30 at least partially extends from the installation cavity 13 to the wire outlet 14 or retracts from the wire outlet 14 into the installation cavity 13. The tooth cleaning device includes an expansion and retraction structure 50, which is arranged in the installation cavity 13 and is used to expand the dental floss holder 30 when the dental floss holder 30 extends out of the housing 10, and to retract the dental floss holder 30 when the dental floss holder 30 retracts into the installation cavity 13.

[0057] It should be noted that when using the dental floss holder 30, only one end of the dental floss 231 needs to be extended from the outlet 14. In other embodiments, when the dental floss holder 30 is relatively small, the dental floss holder 30 can be extended from the outlet 14 as a whole and retracted as a whole after use, which is not limited here.

[0058] In the teeth cleaning device of the present application, the dental floss holder 30 and the dental floss 231 are both stored in the mounting cavity 13 in the initial state. When the dental floss 231 needs to be used, the dental floss holder 30 and the dental floss 231 are first transported from the mounting cavity 13 to the wire outlet 14 by the driving structure 40, and at the same time, the dental floss holder 30 is opened by the expansion and retraction structure 50, so that the dental floss 231 begins to be in a tensioned state. When the dental floss holder 30 and the dental floss 231 are both extended to the appropriate position, the driving structure 40 is stopped, and the user can directly use the dental floss 231; after use, the dental floss holder 30 and the dental floss 231 are driven by the driving structure 40 from the wire outlet 14 into the mounting cavity 13, and before entering the mounting cavity 13, the dental floss holder 30 is retracted by the expansion and retraction structure 50, so as to reduce the volume of the dental floss holder 30 and the dental floss 231 and store them in the storage cavity. By setting the expansion and retraction structure 50, the dental floss holder 30 can be unfolded and the dental floss 231 can be stretched out when in use, and can be folded when stored in the shell 10, thereby preventing the dental floss 231 and the dental floss holder 30 from contacting the outside world, always maintaining a hygienic and sterile state, and making the dental floss holder 30 occupy a small space, so the size of the shell 10 can also be appropriately reduced, thereby making the entire tooth cleaning device occupy a small space, with a compact structure and easy to carry.

[0059] In the specific embodiment, please see Figures 5 to 9 The dental floss rack 30 includes two dental floss rods 31 spaced apart from each other. One end of the two dental floss rods 31 is mounted on the driving structure 40, and the other ends of the two dental floss rods 31 are suspended. The dental floss rack 30 is arranged on the other ends of the two dental floss rods 31, and the expansion and retraction structure 50 can stretch the other ends of the two dental floss rods 31 away from each other or close them together. By fixing one end of the two dental floss rods 31 at an interval and suspending the other end, the other ends of the two dental floss rods 31 are made elastic, and the distance between them can be adjusted by the expansion and retraction structure 50.

[0060] In the specific embodiment, please see Figures 7 to 9 The retracting structure 50 includes two guide rails 51, which are arranged at intervals, and the distance between the two guide rails 51 gradually increases along the extension direction of the dental floss rod 31. The two dental floss rods 31 are provided with guide posts 313, and the two guide posts 313 are respectively slidably arranged on the two guide rails 51. The present application guides the other ends of the two dental floss rods 31 through the two guide rails 51, so as to adjust the distance between the other ends of the two dental floss rods 31, and the structure is simple and occupies a small space. It can be understood that in other embodiments of the present application, according to the actual design situation, it is also possible not to set two guide rails 51, but to directly set two guide grooves arranged at intervals on the inner side of the housing 10, and then slide the two guide posts 313 into the two guide grooves respectively, which is not limited here.

[0061] Specifically, the two guide rails 51 are respectively arranged on the two inner side walls of the housing 10 along the width direction, wherein the extension direction of the dental floss rod 31 is set as the length direction of the housing 10, the spacing distribution direction of the two dental floss rods 31 is set as the width direction of the housing 10, and the height direction of the housing 10 is perpendicular to the length direction and the width direction of the housing 10. When the two guide rails 51 are respectively installed on the two inner side walls of the housing 10 along the width direction, the distance between the two guide rails 51 can be maximized within the existing space, that is, the maximum distance between the two guide rails 51 is larger, so that the distance between the other ends of the two dental floss rods 31 is larger, that is, the distance between the other ends of the two dental floss rods 31 after extending out of the housing 10 can be maximized within the limited space of the housing 10, thereby making the housing 10 compact and easy to carry. It can be understood that in other embodiments of the present application, according to actual design conditions, the above-mentioned guide rails 51 can also be installed at other positions of the housing 10, which is not limited here.

[0062] See also Figure 7 The two guide rails 51 are arranged in an eight-shaped shape, so that the distance between the other ends of the two dental floss rods 31 can be increased slowly or not increased at all when inside the housing 10, and can be increased quickly after extending out of the housing 10. It can be understood that in other embodiments of the present application, the two dental floss rods 31 can also extend straight along the extension direction of the dental floss rods 31, so that the distance between the other ends of the two dental floss rods 31 increases proportionally, which is not limited here.

[0063] The lower sides of the two guide rails 51 are provided with guide rail grooves, and the two guide posts 313 are respectively provided on the upper sides of the two dental floss rods 31, and the two guide posts 313 are respectively slidably provided in the two guide rail grooves. It can be understood that in other embodiments of the present application, the guide posts 313 can also be provided on the guide rails 51, and the guide rail grooves can be provided on the dental floss rods 31, which is not limited here.

[0064] See also Figure 7 , the two guide posts 313 are both arranged near one end of the two dental floss rods 31, so that the distance from the guide posts 313 to the other end of the dental floss rods 31 is long enough, and after the shapes and positions of the two guide rails 51 have been determined, the distance between the other ends of the two dental floss rods 31 can be made larger, thereby reducing the distance between the two guide rails 51, thereby reducing the size of the housing 10, and making the entire dental cleaning device compact. It can be understood that in other embodiments of the present application, according to actual design conditions, the guide posts 313 can also be arranged at other positions in the length direction of the dental floss rods 31, which is not limited here.

[0065] See also Figure 7The dental floss rod 31 includes a thick section 311 and a thin section 312. The thick section 311 extends from one end of the dental floss rod 31 to a guide post 313, and the thin section 312 extends from the guide post 313 to the other end of the dental floss rod 31. The cross-sectional dimension of the thin section 312 is smaller than that of the thick section 311, and the guide post 313 is disposed on the thick section 311. The present application designs the cross-sectional dimension of the thin section 312 to be smaller, so that the thin section 312 has better elasticity and is convenient for the thin section 312 to be opened and closed.

[0066] For details, please refer to Fig.10 The wire-releasing hole 214 and the wire-receiving hole 215 both extend to the upper surface of the cylinder 21. Specifically, the wire-releasing hole 214 extends vertically upward from the wire-releasing cavity 212 to the upper surface of the cylinder 21, and the wire-receiving hole 215 extends vertically upward from the wire-receiving cavity 213 to the upper surface of the cylinder 21. The tensioning member 241 is disposed in front of the cylinder 21 along the extending direction of the dental floss rod 31, so that the dental floss 231 extending from the wire-releasing hole 214 is parallel to the upper surface of the cylinder 21 and is wound around the tensioning member 241 in a V-shape. The two dental floss rods 31 are spaced apart on the upper surface of the cylinder 21 in the initial state, and a wire clamping groove 3140 is provided at the bottom side of the other end of the dental floss rod 31. The two parts of the dental floss 231 located on both sides of the tensioning member 241 are respectively clamped in the wire clamping grooves 3140 of the two dental floss rods 31. In this way, when the two dental floss rods 31 are driven to extend outward by the driving structure 40, the wire clamping grooves 3140 of the two dental floss rods 31 can drive the dental floss 231 to detach from the tensioning member 241, and then the other ends of the two dental floss rods 31 are slowly opened to drive the lower dental floss 231. 1, and the other ends of the two dental flosses 231 stop moving after extending out of the housing 10 to a proper distance. At this time, the dental floss 231 is in the most taut state, which is also the most suitable state for cleaning teeth. After the teeth are cleaned, the driving structure 40 drives the two dental floss rods 31 to be retracted into the installation cavity 13, and the wire clamping groove 3140 drives the dental floss 231 to be retracted until the other ends of the two dental floss rods 31 pass through the tensioning member 241 and are located between the tensioning member 241 and the cylinder 21, and the dental floss 231 is just hung on the tensioning member 241.

[0067] See also Figure 8 and Fig.12, a clamping line 314 is provided at the bottom side of the other end of the dental floss rod 31, and the clamping line 314 is overlapped with the other end of the dental floss rod 31, and a clamping line 3140 is provided on the opposite sides of the two clamping line grooves 3140, and the clamping line grooves 3140 penetrate the clamping line 314 along the length direction of the clamping line 314, and the dental floss 231 parts located on both sides of the tensioning member 241 are clamped on the two clamping line grooves 3140 respectively, and the two clamping line grooves 3140 are opposite to each other and are arranged at intervals, so that the dental floss 231 can be stretched. Specifically, a guide hole 3142 is provided at one end of the clamping line groove 3140 close to the cylinder 21, and the guide hole 3142 includes an eight-shaped guide section and a circular limiting section, and the guide section and the limiting section are connected to each other, and the dental floss 231 is clamped into the limiting section from the guide section and is clamped and limited with the limiting section.

[0068] See also Fig.11 , a first supporting section 316 is provided at the other end of the dental floss rod 31, and the first supporting sections 316 of the two dental floss rods 31 are relatively flush and spaced apart. Similarly, a second supporting section 3141 is also provided at the end of the wire clamping groove 3140 away from the cylinder 21, and the two second supporting sections 3141 are relatively flush and spaced apart, so that the dental floss 231 can be guided and stretched along the width direction of the shell 10, and the two second supporting sections 3141 can support the dental floss 231 to prevent the dental floss 231 from being cut due to a sharp turn.

[0069] In the specific embodiment, please see Figures 7 to 9 The driving structure 40 includes a sliding button 41 and a connecting member 42. The sliding button 41 is slidably disposed on the surface of the housing 10. The connecting member 42 is disposed in the mounting cavity 13. The connecting member 42 is connected to the sliding button 41. One end of the two dental floss rods 31 are respectively disposed on the connecting member 42. In this way, by sliding the sliding button 41 outside the housing 10, the two dental floss rods 31 can be driven to extend toward the outlet 14 or retract into the mounting cavity 13 through the connecting member 42. The present application can push the sliding button 41 manually to push out the dental floss 231 for use. Even if the entire dental cleaning device has no electricity, the dental cleaning device can be used normally and is easy to use.

[0070] See also Figure 1 , Figures 3 to 7 The upper surface of the housing 10 is provided with a waist-shaped slide groove 15, and the slide button 41 is in the shape of a circular plate and slides along the slide groove 15. A slot is provided at the bottom of the slide button 41, and a hook 421 is provided at the top of the connecting member 42.

[0071] See also Figures 7 to 9 The driving structure 40 also includes a transmission structure 43, which is connected between the connecting member 42 and the rotating shaft 22. The transmission structure 43 can drive the rotating shaft 22 to rotate when the sliding button 41 slides back. In actual operation, when the sliding button 41 slides forward, the dental floss rod 31 can be driven to extend out of the housing 10 through the connecting member 42, but the rotating shaft 22 cannot be driven to rotate; and when the sliding button 41 slides backward, the dental floss rod 31 can be driven to be retracted into the installation cavity 13 through the connecting member 42, and the rotating shaft 22 can also be driven to rotate through the transmission structure 43. The rotation of the rotating shaft 22 causes the dental floss reel 23 to output new dental floss 231 to the wire release hole 214, and the used dental floss 231 to enter the wire take-up cavity 213 from the wire take-up hole 215, and finally be wound on the rotating shaft 22.

[0072] In the specific embodiment, please see Figures 7 to 9 The transmission structure 43 includes a ratchet bar 431 and a ratchet gear 432.

[0073] Specifically, the ratchet bar 431 is provided with a plurality of first ratchet teeth along the extension direction of the dental floss rod 31, and each first ratchet tooth is arranged obliquely toward the retraction direction of the dental floss rod 31. The ratchet gear 432 is provided with second ratchet teeth along the circumferential direction, and each second ratchet tooth is arranged obliquely in the clockwise direction. Figure 8 When the ratchet bar 431 moves along the extension direction of the dental floss rod 31 and passes through the ratchet gear 432, the first ratchet teeth and the second ratchet teeth have the same inclination direction, so the first ratchet teeth cannot cooperate with the second ratchet teeth, thereby failing to drive the ratchet gear 432 to rotate; see Fig. 9 When the ratchet bar 431 moves along the retraction direction of the dental floss rod 31 and passes through the ratchet gear 432, the inclination direction of each first ratchet tooth is opposite to that of the second ratchet tooth, so that each first ratchet tooth can engage with the second ratchet tooth, thereby driving the ratchet gear 432 to rotate, and then driving the rotating shaft 22 to rotate, thereby realizing the retracting and releasing operation of the retracting and releasing structure 20.

[0074] See also Figure 7 The connecting member 42 is a long frame structure and is arranged vertically. The two mounting posts 422 are respectively arranged at the bottom of the connecting member 42 and are arranged at intervals.
