Description

Technical Field

[0001] This utility model relates to the field of dental polishing equipment technology, specifically a dental grinding and polishing device. Background Technology

[0002] Brushing your teeth every day can keep them clean to some extent, but tartar, plaque, and stains can still accumulate on the surface of your teeth. The conventional way to remove these deposits is through professional teeth cleaning with a dental polisher.

[0003] Some traditional dental polishing devices use bolts or screws to secure the polishing head to the device. Replacing the polishing head requires unscrewing multiple sets of bolts or screws, which is time-consuming and can lead to stripped screws after prolonged use, making disassembly difficult. While some polishing heads use magnetic connections, which are easier to remove, these connections require high-quality materials. If the magnetism is too weak, the polishing head may accidentally fall off during use; if the magnetism is too strong, it requires excessive force for disassembly, potentially causing inconvenience to the user. Therefore, appropriate technical solutions are needed to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a tooth polishing device to solve the problems mentioned in the background art.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments. Example

[0019] Please see Figure 1-4A dental polishing device includes a housing 1, a power element disposed within the housing 1, a first bevel gear 2, a second bevel gear 3, a first rotating shaft 4, and a second rotating shaft 5. The first rotating shaft 4 is vertically rotatable within the housing 1 via the power element, and the first bevel gear 2 is mounted at its top end. The second rotating shaft 5 is horizontally rotatable within the housing 1, and the second bevel gear 3, meshing with the first bevel gear 2, is mounted on the second rotating shaft 5. A polishing head 6 is detachably mounted at the end of the second rotating shaft 5 via a plug-in mechanism, the plug-in mechanism including a fixing plate. 7. A fixed post 9, a fixing element 10, a movable element 11, and a limiting cylinder 12 are provided. The fixed disk 7 is fixedly installed at the end of the second rotating shaft 5, and multiple protruding posts 8 are fixedly arranged in an array on the fixed disk 7. A fixed post 9 is also fixedly installed at the center of the fixed disk 7. A fixing element 10 is fixedly installed at the end of the fixed post 9. The fixing element 10 has an umbrella-shaped structure. A movable element 11 is movably installed on the rod between the fixing element 10 and the fixed disk 7. The movable element 11 is composed of two conical truncated cones. The limiting cylinder 12 is fixedly installed on the side of the polishing head 6. The end face of the limiting cylinder 12 has multiple grooves 13 that engage with the protruding post 8. A first spring 14 is installed in each groove 13. A movable rod 15 is also movably installed on the side wall of the limiting cylinder 12 via a second spring 16. A limiting block 17 is installed at the end of the movable rod 15 inside the limiting cylinder 12. The end face of the limiting block 17 has a wedge-shaped structure. By setting up the fixing plate 7, fixing post 9, fixing member 10, movable member 11 and limiting cylinder 12, when the limiting cylinder 12 installed on the side of the polishing head 6 is inserted into the fixing post 9 at the end of the second rotating shaft 5, multiple braking mechanisms inside the limiting cylinder 12 are activated. The wedge-shaped structure at the end of the block cooperates with the fixing member 10. With the action of the second spring 16 and the movable rod 15, the brake block can be locked between the movable member 11 and the fixing member 10. With the cooperation of multiple protrusions 8 at the end of the limiting cylinder 12 and multiple grooves 13 on the fixing plate 7, the limiting cylinder 12 can be fixed on the fixing plate 7, thereby realizing the quick installation of the polishing head 6. Conversely, when it is necessary to disassemble the polishing head 6, it is only necessary to press the polishing head 6 twice to release the fixing of the limiting cylinder 12 on the fixing plate 7 and realize the quick disassembly of the polishing head 6. It has the advantage of convenient disassembly and assembly.

[0020] Among them, a flange 18 is installed on the end face of the limiting cylinder 12 away from the fixed plate 7. The flange 18 is detachably installed on the polishing head 6 by screws. The setting of the flange 18 makes it convenient to disassemble the limiting cylinder 12 on the side of the polishing head 6, thereby realizing the recycling and reuse of the limiting cylinder 12.

[0021] Specifically, the outer casing 1 includes a polishing part 20, a connecting part 21, and a handle part 22 connected sequentially from top to bottom. The polishing head 6 is rotatably mounted on the polishing part 20. The polishing part 20 is located below the polishing head 6 and is also provided with an illumination lamp 23. The illumination lamp 23 is provided to facilitate observation of dirt on the teeth and to facilitate polishing the teeth.

[0022] In addition, a control board 24 is provided on the handle 22. The control board 24 is provided with a first switch 25 and a second switch 26. Specifically, the first switch 25 is used to control the opening and closing of the power element to control the rotation or stopping of the polishing head 6, and the second switch 26 is used to control the opening or closing of the lighting lamp 23. Example

[0023] This embodiment is an improvement on embodiment 1, specifically as follows:

[0024] Please see Figure 4 The fixing post 9 is located on the rod between the movable part 11 and the fixed part 10 and is also fitted with a third spring 19. The third spring 19 is provided so that after the movable part 11 is driven to move towards the fixed part 10, it can drive the movable part 11 to separate from the fixed part 10. On the secondary insertion limiting cylinder 12, it ensures that the brake block can be locked between the fixed part 10 and the movable part 11, which further facilitates the installation of the polishing head 6.

[0025] Specifically: When installing the polishing head 6, first align the limiting cylinder 12 on the side of the polishing head 6 with the fixing plate 7, ensuring that the multiple protrusions 8 on the fixing plate 7 correspond one-to-one with the grooves 13 at the end of the limiting cylinder 12. Then press the polishing head 6. When the polishing head 6 pushes the limiting cylinder 12 towards the limiting plate, the wedge-shaped structure at the ends of the multiple brake blocks inside the limiting cylinder 12 engages with the fixing member 10. Combined with the action of the second spring 16 and the movable rod 15, the brake blocks can be locked between the movable member 11 and the fixing member 10, cooperating with the multiple protrusions 8 at the end of the limiting cylinder 12 and the grooves 13 on the fixing plate 7. The multiple grooves 13 allow the limiting cylinder 12 to be fixed on the fixed plate 7, thereby enabling the quick installation of the polishing head 6. Conversely, when it is necessary to disassemble the polishing head 6, simply press the polishing head 6 twice, causing the polishing head 6 to move the brake block inside the limiting cylinder 12 to below the movable part 11. During the process of the limiting cylinder 12 being pushed up in the opposite direction by multiple second springs 16, the brake block first pushes up the movable part 11, making the movable part 11 fit with the fixed part 10, and then slides out along the inclined surface of the movable part 11, thereby releasing the fixed installation of the limiting cylinder 12 and the fixed plate 7, and quickly disassembling the polishing head 6.
