Description

Technical Field

[0001] This invention relates to the field of dental plaque removal technology, and in particular to a dental caries plaque removal device. Background Technology

[0002] Dental plaque, also known as dental caries plaque, is the core culprit behind tooth decay. Dental plaque refers to a thin film-like substance formed by the mixture of bacteria, food debris, and salivary mucoproteins in the oral cavity. It is especially common for patients who are bedridden for extended periods to accumulate more dental plaque on their teeth. To clean dental plaque, first apply a plaque disclosing agent to the teeth, then rinse off any excess agent with water. Next, use a water flosser to rinse the plaque. Finally, apply a fluoride gel to the teeth to prevent tooth decay and strengthen them. The water flosser is a dental plaque cleaner.

[0003] Common dental plaque cleaners use water jets to rinse away plaque, but relying solely on the impact of the water jets is insufficient to effectively clean plaque between teeth, and the thoroughness of plaque removal needs to be improved. Therefore, this application provides a dental plaque cleaner to meet this need. Summary of the Invention

[0004] This invention provides a dental plaque cleaning device to address the problem that the thoroughness of dental plaque removal needs to be improved.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A dental plaque cleaner includes a handle and a nozzle mounted on top of the handle, and further includes: The cleaning mechanism includes a connector sleeved on the water outlet end of the nozzle, a bent pipe fixed to the end of the connector, a round head threaded to the end of the bent pipe, a water outlet at the end of the round head, a dental floss rotatably connected to the end of the round head, a hook fixed to the end of the dental floss, a ring fixed to the outer wall of the nozzle, a retaining strip fixed to the outer wall of the ring, and the hook hanging on the retaining strip. When cleaning between teeth, the floss cuts into the gaps, and water sprays out simultaneously from the nozzle.

[0006] Preferably, the top and bottom of the ring are each fixed with a plurality of ribs, which are fixed to the outer wall of the nozzle.

[0007] Preferably, the top and bottom of the ring are each fixed with a plurality of ribs, the ribs are fixed to the outer wall of the nozzle, and the ribs are located between two adjacent ribs.

[0008] Preferably, the length of the reinforcing bar is less than the length of the rib.

[0009] Preferably, a round seat is fixed to the end of the round head, and a turntable is fixed to the end of the dental floss away from the hook, with the turntable rotatably connected inside the round seat.

[0010] Preferably, the hook is provided with a shielding component, which is used to block the water flow along the dental floss.

[0011] Preferably, the shielding assembly includes a shield fixed on the hook, the shield having a through hole corresponding to the dental floss, the dental floss passing through the through hole and through the shield and then fixedly connected to the end of the hook, and water outlet holes being provided on opposite sides of the shield.

[0012] Preferably, the connection between the cover and the hook has an integrally formed curved portion.

[0013] Preferably, the hook is fixed with a reinforcing rib, which is fixed to the outer wall of the cover.

[0014] Preferably, a gathering cover is fixed to the inner wall of the baffle corresponding to the through hole, the dental floss is located inside the gathering cover, and the gathering cover is trumpet-shaped.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up dental floss, after the water jet from the nozzle has rinsed the tooth surface, the dental floss is then inserted into the gaps between the teeth, and the floss is moved to clean the plaque in the gaps. At the same time, water jets are sprayed from the nozzle to rinse, thereby improving the thoroughness of plaque removal.

[0016] By setting up a hook and a turntable, the hook is hung on the clip, and then the round head is tightened to the end of the bend to install dental floss. During the tightening of the round head, in order to prevent the dental floss from rotating with the round head, the turntable at the end of the dental floss is rotated and connected inside the round seat. The rotational connection not only connects the dental floss to the round head, but also prevents the dental floss from rotating with the round head, thereby preventing the dental floss from getting knotted, tangled, or broken.

[0017] By incorporating ribs and stiffeners, the retaining strip is connected to the outer wall of the nozzle via a ring. To distribute the force at the connection between the ring and the outer wall of the nozzle, multiple stiffeners are fixed at the top and bottom of the ring. These stiffeners increase the contact area between the ring and the nozzle, thereby dispersing the force at the connection and preventing localized deformation of the nozzle. Furthermore, to enhance the overall structural strength of the nozzle, ribs are also fixed to the outer wall of the nozzle, further improving its resistance to deformation under stress.

[0018] By setting up a baffle that is fixed to the hook, when the dental floss is removed from the gap between the teeth, in order to prevent the water from spraying out of the outlet from flowing randomly, the water from the outlet can flow into the baffle along the dental floss and flow out from the outlet hole of the baffle, thus preventing the water from splashing randomly.

[0019] By setting up a water-gathering hood, the water flow along the floss is gathered, allowing the water to flow smoothly into the baffle. At the same time, the water-gathering hood can reduce the size of the opening at the through hole, effectively preventing water droplets that splash into the baffle after entering it from splashing out of the baffle, thereby improving the baffle's ability to collect water.

[0020] By incorporating a curved section, the water flow entering the baffle can be gathered, allowing the water to flow smoothly out of the outlet and preventing water from accumulating inside the baffle. Attached Figure Description

[0023] As shown in the figure, specific structures and devices are labeled in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0024] The dental plaque cleaner provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1-8 As shown, an embodiment of the present invention provides a dental plaque cleaner, including a handle 1 and a nozzle 2 mounted on the top of the handle 1, and further comprising: The cleaning mechanism 3 includes a connector 5 sleeved on the water outlet end of the nozzle 2. A bend 6 is fixed to the end of the connector 5. A round head 7 is threaded to the end of the bend 6. A water outlet 20 is opened at the end of the round head 7. A dental floss 4 is rotatably connected to the end of the round head 7. A hook 8 is fixed to the end of the dental floss 4. A ring 9 is fixed to the outer wall of the nozzle 2. A retaining strip 10 is fixed to the outer wall of the ring 9. The hook 8 is hung on the retaining strip 10. When cleaning between teeth, the dental floss 4 is inserted into the gaps between teeth, and water is sprayed out simultaneously from the outlet 20. The handle 1 allows for easy adjustment of the spray angle and position of the nozzle 2. The spray from the nozzle 2 rinses the tooth surface, achieving initial removal of plaque. The connector 5 is tightly fitted onto the water outlet of the nozzle 2, and the inner wall of the connector 5 has a sealing ring to seal the connection between the connector 5 and the water outlet of the nozzle 2, effectively preventing water leakage from the connection point. The water flow is altered by the angle design of the bend 6. The direction allows the outlet 20 of the round head 7 to be aligned with the interdental area. The round head 7 is threadedly connected to the curved tube 6, making it easy to install and remove, and facilitating the replacement of dental floss 4. The outlet 20 at the end of the round head 7 can spray a fine stream, which, together with the dental floss 4, forms a dual cleaning of scraping and rinsing. The dental floss 4 can penetrate deep into the interdental spaces to scrape away plaque. The hook 8 and the clip 10 work together to enable quick installation and fixation of the dental floss 4. The ring 9 provides a stable installation base for the clip 10, ensuring that the dental floss 4 does not loosen when under force.

[0026] like Figure 3 As shown in this embodiment, multiple ribs 11 are fixed at the top and bottom of the ring 9. The ribs 11 are fixed to the outer wall of the nozzle 2 and are distributed longitudinally along the outer wall of the nozzle 2, forming an integrated support structure with the nozzle 2. This can significantly enhance the overall structural strength and deformation resistance of the nozzle 2. When the dental floss 4 cuts into the gap between teeth and moves, the force will be transmitted to the nozzle 2 through the retaining strip 10 and the ring 9. The ribs 11 can effectively disperse this stress, prevent the nozzle 2 from deforming due to localized stress concentration, extend the service life of the nozzle 2, and at the same time ensure the stability of the water flow output, preventing the water flow from shifting due to the deformation of the nozzle 2 and affecting the cleaning effect.

[0027] like Figure 3As shown in this embodiment, multiple ribs 12 are fixed at the top and bottom of the ring 9. The ribs 12 are fixed to the outer wall of the nozzle 2 and are located between two adjacent ribs 11. The ribs 12 are vertically distributed at the connection between the ring 9 and the nozzle 2, further expanding the contact area between the ring 9 and the nozzle 2, so that the stress can be distributed more evenly, rather than concentrated at the connection edge between the ring 9 and the nozzle 2, effectively preventing the nozzle 2 from being dented or deformed due to excessive local stress.

[0028] like Figure 3 As shown in this embodiment, the length of the rib 12 is less than the length of the rib 11. The shorter rib 12 mainly acts on the connection area between the ring 9 and the nozzle 2, accurately dispersing the local stress in this key part and avoiding the increase in the overall volume of the nozzle 2 and the inconvenience of operation due to excessive length. The longer rib 11 improves the overall structural rigidity and deformation resistance of the nozzle 2. The combination of the two lengths and their complementary functions achieve the dual effect of local reinforcement and overall support while minimizing the increase in volume and weight. This ensures structural stability while also taking into account the flexibility and comfort during use.

[0029] like Figure 5 As shown in this embodiment, a round base 19 is fixed to the end of the round head 7, and a turntable 21 is fixed to the end of the dental floss 4 away from the hook 8. The turntable 21 is rotatably connected inside the round base 19, and the round base 19 provides stable rotational support for the turntable 21. The turntable 21 is fixedly connected to the dental floss 4. When the rotating round head 7 is threadedly connected to the bent tube 6, the round base 19 rotates on the turntable 21, preventing the dental floss 4 from rotating synchronously with the round head 7. This effectively prevents the dental floss 4 from getting tangled, tangled, or broken, ensuring the installation efficiency of the dental floss 4. At the same time, the rotational design of the turntable 21 does not affect the tension adjustment of the dental floss 4, so that the dental floss 4 can always maintain a suitable tightness, ensuring the effectiveness and comfort when scraping plaque.

[0030] like Figure 2 As shown in this embodiment, the hook 8 is provided with a shielding component 13. The shielding component 13 is used to block the water flow along the dental floss 4. When the water flow from the outlet 20 flows along the dental floss 4, it is easy to splash onto the area around the mouth or clothing. The shielding component 13 can effectively block this water flow and keep the environment clean. At the same time, the shielding component 13 can guide the water flow to drain in an orderly manner.

[0031] like Figure 6As shown in this embodiment, the shielding component 13 includes a shield 14 fixed on the hook 8. The shield 14 has a through hole 17 corresponding to the dental floss 4. The dental floss 4 passes through the through hole 17 and through the shield 14 and is fixedly connected to the end of the hook 8. Water outlet holes 16 are provided on opposite sides of the shield 14. The shield 14 can collect the water flowing along the dental floss 4 and prevent the water from splashing in all directions. The design of the dental floss 4 passing through the shield 14 allows the water to completely enter the interior of the shield 14 and then be quickly discharged through the water outlet holes 16 on the opposite side, preventing the water from accumulating inside the shield 14 and forming water accumulation, ensuring the continuous and effective operation of the shielding component 13. At the same time, the distribution design of the water outlet holes 16 can guide the water to be discharged in a designated direction, preventing disorderly water discharge from interfering with the cleaning of dental plaque.

[0032] like Figure 6 As shown in this embodiment, the connection between the baffle 14 and the hook 8 is integrally formed with a curved part 18. The curved part 18 adopts an arc-shaped transition design, which can guide the water flow inside the baffle 14 to converge towards the water outlet 16, avoid water flow from stagnating at the connection between the baffle 14 and the hook 8, improve the smoothness of drainage, and at the same time, the arc-shaped structure has no sharp edges, so it will not scratch the skin around the mouth during use, thus improving the safety and comfort of use.

[0033] like Figure 6 As shown in this embodiment, a reinforcing rib is fixed on the hook 8. The reinforcing rib is fixed to the outer wall of the baffle 14 and distributed on the outer wall of the baffle 14. This can significantly improve the connection stability between the baffle 14 and the hook 8, and prevent the baffle 14 from falling off due to long-term water flow impact, external force when removing and installing dental floss 4, or slight collisions during normal use. At the same time, the reinforcing rib can enhance the structural strength of the baffle 14 itself, prevent the baffle 14 from deforming due to force, ensure the accurate position of the through hole 17 and the water outlet 16, and ensure the stable performance of the shielding and drainage functions.

[0034] like Figure 7 and Figure 8 As shown in this embodiment, a gathering cover 15 is fixed on the inner wall of the baffle 14 corresponding to the through hole 17. The dental floss 4 is located inside the gathering cover 15, and the gathering cover 15 is funnel-shaped. The large end of the funnel-shaped gathering cover 15 faces the direction of the water flow from the dental floss 4, which can efficiently gather the dispersed water flow along the dental floss 4 and guide the water flow into the interior of the baffle 14, preventing the water flow from flowing out from around the through hole 17. Its small end reduces the entrance area of ​​the water flow into the baffle 14, which can block the water droplets splashing when the water flow hits the inner wall of the baffle 14, further improving the water flow collection effect.

[0035] Working principle: Hold the handle 1 and adjust the spray angle of the nozzle 2 so that the water outlet sprays water to rinse the tooth surface, achieving the initial cleaning of dental plaque. Then, the cleaning mechanism 3 can be used to treat the dental plaque in the gaps between the teeth. Next, install dental floss 4 to clean plaque between teeth. During installation, hook 8 is hung on clip 10, and round head 7 is threaded to the end of bend 6. A turntable 21 is fixed to the end of dental floss 4 away from hook 8. Turntable 21 is rotatably connected to round seat 19 of round head 7. During the process of rotating round head 7 to tighten it, dental floss 4 can be effectively prevented from rotating with round head 7, thus preventing dental floss 4 from knotting, tangling or breaking, thus ensuring normal use of dental floss 4. After dental floss 4 is installed, hold handle 1 and move nozzle 2 to insert dental floss 4 into the gap between teeth. Then move dental floss 4 to scrape away plaque between teeth. At the same time, water is still sprayed from nozzle 2. The water flows through connector 5 and bend 6 and then into round head 7, and then sprays out from outlet 20 at the end of round head 7. The water flow and dental floss 4 work together to flush and clean the plaque in the gap between teeth, improving the thoroughness of plaque cleaning. When dental floss 4 is inserted into or moved within the gaps between teeth, the connection between the nozzle 2 and the ring 9 will be subjected to force. In order to distribute the force at the connection between the ring 9 and the outer wall of the nozzle 2, multiple ribs 11 at the top and bottom of the ring 9 are fixed to the outer wall of the nozzle 2 to enhance the overall resistance to deformation of the nozzle 2. Multiple ribs 12 at the top and bottom of the ring 9 increase the contact area between the ring 9 and the nozzle 2, distribute the force at the connection, avoid local deformation of the nozzle 2, and thus improve the durability of the nozzle 2. When dental floss 4 is removed from one gap and inserted into another, the water flow from the outlet 20 will flow along dental floss 4. The baffle 14 on the hook 8 acts as a shield. The water flow passes through the through hole 17 of the baffle 14 and enters the interior of the baffle 14. The funnel-shaped gathering cover 15 at the through hole 17 can gather the water flow and reduce the splashing of water droplets when the water flow hits the inner wall of the baffle 14. The curved part 18 at the connection between the baffle 14 and the hook 8 further guides the water flow, so that the water flow can be smoothly discharged from the outlet hole 16 on the opposite side of the baffle 14 to avoid accumulation. The reinforcing rib on the hook 8 is fixed to the outer wall of the baffle 14 to improve the connection stability between the baffle 14 and the hook 8. After use, unscrew the round head 7 from the end of the curved tube 6, and then remove the hook 8 from the clip 10 to complete the disassembly of the dental floss 4. After disassembly, simply discard it.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
