Technical Field
[0001] This application relates to the field of dental grinding equipment technology, specifically a dental grinding instrument. Background Technology
[0002] A dental polisher is a grinding device used to polish dentures. It can be used to repair wear on the surface of dentures. After polishing the worn areas, the worn parts are repaired to make the denture surface more aesthetically pleasing and allow the denture to be used normally.
[0003] A prior patent (publication number: CN222345198U) discloses a dental grinding instrument, belonging to the field of dental grinding technology. It includes a grinding instrument body with a grinding mechanism for grinding dentures mounted on its top. A hand support assembly for supporting the arm is mounted on the outer side of the grinding instrument body. The hand support assembly includes two support plates fixed to both sides of the grinding instrument body, a lifting plate fixed to the top of the support plates, a fixing block fixed to the top front of the lifting plate, a rotating rod rotatably connected to the top of the fixing block via a bearing, a hand screw threaded to one side of the fixing block, a rotating block fixed to the top of the rotating rod, an adjustment groove formed on the top of the rotating block, and an adjustment rod rotatably connected to the inner side of the adjustment groove via a bearing. This dental grinding instrument can support the operator's arm at different angles, allowing most operators to perform denture grinding work in a relatively comfortable posture.
[0004] The aforementioned grinding machine cannot collect the grinding debris during use, which causes the debris to affect the grinding environment. At the same time, the grinding debris will be scattered in the air and inhaled by the workers, affecting their health. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a dental grinding instrument that can collect the debris generated during grinding, preventing the debris from affecting the grinding environment and preventing the debris from being scattered in the air and inhaled by workers. This solves the problem that grinding instruments cannot collect the debris generated during use, which causes the debris to affect the grinding environment and to be scattered in the air and inhaled by workers, affecting their health.
[0006] To achieve the aforementioned purpose of absorbing the debris generated during grinding, preventing the debris from affecting the grinding environment, and preventing the debris from being scattered in the air and inhaled by workers, this application provides the following technical solution: a dental grinding instrument, including a base, a guide arm provided on the top of the base, a grinding assembly installed at one end of the guide arm, the grinding assembly including a grinding machine, a dust suction hood provided on the outer surface of the end of the grinding machine near the grinding head, the dust suction hood surrounding the outside of the grinding head at one end of the grinding machine, a dust suction branch pipe provided on the top of the dust suction hood, one end of the dust suction branch pipe being located at the bottom of a manifold box, the outer surface of the middle part of the manifold box being provided on the top of a protective sleeve via a support frame, a main dust suction pipe connected to the top of the manifold box via a quick-connect assembly, one end of the main dust suction pipe being located on the top of a dust suction mechanism, the dust suction mechanism being located on the top of the base, an electromagnetic base being provided on the top of the base, and a clamp being installed on the top of the electromagnetic base.
[0007] The above solution utilizes a dust collection mechanism to generate suction power in the main dust collection pipe, which in turn causes the manifold box to work with the dust collection branch pipe to generate suction power in the dust collection hood. This allows the dust collection hood to pick up the debris generated during grinding, thus preventing the debris from affecting the grinding environment and preventing it from being scattered in the air and inhaled by workers.
[0008] Furthermore, the end of the dust hood furthest from the dust suction branch pipe is designed to extend outwards.
[0009] The above solution expands the dust collection range by extending one end of the dust hood, making it easier for the dust generated during grinding to be sucked into the dust hood, improving dust collection efficiency and reducing the possibility of dust escaping into the surrounding environment.
[0010] Furthermore, the top of the dust hood is provided with multiple dust suction branches, which are arranged in a ring array on the top of the dust hood. The ends of the multiple dust suction branches away from the dust hood are arranged in a ring array at the bottom of the manifold box, and the multiple dust suction branches surround the outside of the grinder.
[0011] The above scheme, with its ring array design of multiple suction pipes, ensures that the suction power is evenly distributed in all areas of the dust hood, preventing debris from accumulating or escaping due to insufficient local suction power, and further improving the comprehensiveness and stability of debris collection.
[0012] Furthermore, a protective sleeve is provided on the outer surface of the middle part of the grinder, and the protective sleeve wraps around multiple dust suction pipes.
[0013] The above solution provides a high degree of integrity to the outer surface of the grinding component, making it easy to hold. The sleeve also protects the suction pipe and makes its installation more secure.
[0014] Furthermore, a non-slip leather sleeve is provided on the outer surface of the middle part of the sheath.
[0015] The above solution increases the friction when the operator holds the grinder, improving the stability and safety of the operation. It is especially suitable for long-term grinding operations, reducing operational errors caused by hand slippage.
[0016] Furthermore, the main suction pipe is a deformable flexible hose.
[0017] The above solution allows the flexible hose to bend or adjust its angle according to the movement of the grinding components.
[0018] Furthermore, a lighting lamp is mounted on the outer side of the clamp via a connecting assembly.
[0019] With the above solution, the lighting can provide sufficient light to the grinding area, ensuring that the operator can clearly observe the grinding details. It is especially suitable for precision grinding or processing of complex structures, improving the accuracy and efficiency of the operation. At the same time, the lighting is installed on the outside of the fixture through the connecting component, so that the lighting can move with the movement and angle change of the fixture. When the angle of the denture is adjusted by the fixture, the lighting can always provide illumination to the grinding area of the denture.
[0020] Furthermore, the connecting assembly includes a connecting ring, the inner side of which is disposed on the outer surface of the middle part of the clamp via a fixing rod, a connecting sleeve is slidably disposed on the outer surface of the middle part of the connecting ring, and a lighting lamp is disposed on the top of the connecting sleeve via a support frame. The side of the connecting sleeve near the clamp is semi-open, and the semi-open position of the connecting sleeve is adapted to the position of the fixing rod between the connecting ring and the clamp.
[0021] The above solution allows the sliding design of the connecting sleeve to freely adjust the position of the lighting lamp along the connecting ring, preventing the lighting lamp from moving between the clamp and the operator and affecting the operator's observation of the denture on the clamp when the angle of the clamp is adjusted. The semi-opening on one side of the connecting sleeve can prevent the movement of the connecting sleeve from being affected by the fixing rod between the connecting ring and the clamp.
[0022] Furthermore, the connecting ring has a quadrilateral cross-section, and the shape of the outer surface of the connecting ring is adapted to the shape of the inner wall of the connecting sleeve. A locking screw is threaded into the top threaded hole of the connecting sleeve, and the threaded hole at the top of the connecting sleeve penetrates through the top of the connecting sleeve.
[0023] The above solution allows the quadrilateral cross-section of the connecting ring to fix the angle of the connecting sleeve on the connecting ring, thereby fixing the angle of the lighting lamp and ensuring the stable direction of the lighting lamp. By rotating the locking screw, one end of the locking screw abuts against the top of the connecting ring through the threaded hole at the top of the connecting sleeve, which can fix the position of the connecting sleeve on the connecting ring and improve the stability of the lighting lamp when adjusting the angle of the clamp.
[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0025] This dental polishing instrument uses a dust extraction mechanism to generate suction force in the main suction pipe, which in turn causes the manifold box to work with the side suction pipe to generate suction force in the dust extraction hood. This allows the dust extraction hood to pick up the debris generated during polishing, thus preventing the debris from affecting the polishing environment and preventing the debris from being scattered in the air and inhaled by the staff.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0034] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a dental polishing device includes a base 1, a guide arm 2 on the top of the base 1, a polishing assembly 3 on one end of the guide arm 2, the polishing assembly 3 including a polisher 301, a dust suction hood 4 on the outer surface of the end of the polisher 301 near the polishing head, the dust suction hood 4 surrounding the outside of the polishing head at one end of the polisher 301, a dust suction branch pipe 5 on the top of the dust suction hood 4, one end of the dust suction branch pipe 5 being located at the bottom of a manifold 6, the outer surface of the middle part of the manifold 6 being located on the top of a protective sleeve 302 via a support frame, a main dust suction pipe 8 being connected to the top of the manifold 6 via a quick-connect assembly 7, one end of the main dust suction pipe 8 being located on the top of a dust suction mechanism 9, the dust suction mechanism 9 being located on the top of the base 1, an electromagnetic base 11 being located on the top of the base 1, and a clamp 12 being installed on the top of the electromagnetic base 11.
[0035] Please see Figure 1 , Figure 2 and Figure 4 The end of the dust hood 4 furthest from the dust suction branch pipe 5 is designed to expand outward. This expansion of the dust hood 4 can increase the range of debris collection, making it easier for debris generated during the grinding process to be sucked into the dust hood 4, improving debris collection efficiency and reducing the possibility of debris escaping into the surrounding environment.
[0036] Please see Figure 1 , Figure 2 and Figure 4 The top of the dust hood 4 is provided with multiple suction pipes 5, which are arranged in a ring array on the top of the dust hood 4. The ends of the multiple suction pipes 5 away from the dust hood 4 are arranged in a ring array at the bottom of the manifold box 6. The multiple suction pipes 5 surround the outside of the grinder 301. The ring array design of the multiple suction pipes 5 can ensure that the suction force in each area of the dust hood 4 is evenly distributed, avoiding the accumulation or escape of debris due to insufficient local suction force, and further improving the comprehensiveness and stability of debris collection.
[0037] Please see Figure 1 , Figure 3 and Figure 4 The outer surface of the middle part of the grinder 301 is provided with a protective sleeve 302. The protective sleeve 302 wraps around multiple suction pipes 5. The protective sleeve 302 makes the outer surface of the grinding component 3 more integrated, making it easier to hold the grinding component 3. At the same time, the protective sleeve 302 can protect the suction pipes 5 and make the installation of the suction pipes 5 more stable.
[0038] Please see Figure 1 , Figure 2 and Figure 4The outer surface of the middle part of the protective sleeve 302 is provided with an anti-slip leather sleeve 10. The anti-slip leather sleeve 10 can increase the friction when the operator holds the grinder 301, improve the stability and safety of operation, and is especially suitable for long-term grinding operations, reducing operational errors caused by hand slippage.
[0039] Please see Figure 1 , Figure 2 and Figure 3 The main suction tube 8 is a deformable hose, and the design of the deformable hose makes it easy for the main suction tube 8 to bend or adjust its angle according to the movement of the grinding component 3.
[0040] Please see Figure 1 , Figure 2 and Figure 3 An illumination lamp 14 is mounted on the outside of the clamp 12 via a connecting assembly 13. The illumination lamp 14 provides sufficient light to the grinding area, ensuring that the operator can clearly observe the grinding details. It is especially suitable for precision grinding or processing of complex structures, improving the accuracy and efficiency of the operation. At the same time, the illumination lamp 14 is mounted on the outside of the clamp 12 via the connecting assembly 13, so that the illumination lamp 14 can move with the movement and angle change of the clamp 12. When the angle of the denture is adjusted by the clamp 12, the illumination lamp 14 can always provide illumination to the grinding area of the denture.
[0041] Please see Figure 1 , Figure 2 and Figure 5 The connecting component 13 includes a connecting ring 1301. The inner side of the connecting ring 1301 is fixed to the outer surface of the middle part of the clamp 12 via a fixing rod. A connecting sleeve 1302 is slidably disposed on the outer surface of the middle part of the connecting ring 1301. A lighting lamp 14 is disposed on the top of the connecting sleeve 1302 via a support frame. The side of the connecting sleeve 1302 near the clamp 12 is semi-open. The semi-open position of the connecting sleeve 1302 is adapted to the position of the fixing rod between the connecting ring 1301 and the clamp 12. The sliding design of the connecting sleeve 1302 allows the position of the lighting lamp 14 to be freely adjusted along the connecting ring 1301, preventing the lighting lamp 14 from moving between the clamp 12 and the operator due to the adjustment of the angle of the clamp 12, thus affecting the operator's observation of the denture on the clamp 12. The semi-open position of the connecting sleeve 1302 can prevent the movement of the connecting sleeve 1302 from being affected by the fixing rod between the connecting ring 1301 and the clamp 12.
[0042] Please see Figure 1 , Figure 2 and Figure 5The connecting ring 1301 has a quadrilateral cross-section. The shape of the outer surface of the connecting ring 1301 matches the shape of the inner wall of the connecting sleeve 1302. A locking screw 15 is threaded into the threaded hole at the top of the connecting sleeve 1302. The threaded hole at the top of the connecting sleeve 1302 passes through the top of the connecting sleeve 1302. The quadrilateral cross-section of the connecting ring 1301 can fix the angle of the connecting sleeve 1302 on the connecting ring 1301, thereby fixing the angle of the lighting lamp 14 and ensuring the stable pointing of the lighting lamp 14. By rotating the locking screw 15, one end of the locking screw 15 abuts against the top of the connecting ring 1301 through the threaded hole at the top of the connecting sleeve 1302, which can fix the position of the connecting sleeve 1302 on the connecting ring 1301 and improve the stability of the lighting lamp 14 when adjusting the angle of the clamp 12.
[0043] In this embodiment, a dental polishing instrument operates by means of a dust collection mechanism 9, which causes the main dust collection pipe 8 to generate suction force. This, in turn, causes the manifold box 6 to work with the dust collection branch pipe 5 to generate suction force in the dust collection hood 4. The dust collection hood 4 then picks up the debris generated during polishing, thus achieving the effect of picking up the debris generated during polishing, preventing the debris from affecting the polishing environment, and preventing the debris from being scattered in the air and inhaled by the staff.
[0044] The working principle of the above embodiment is as follows: The denture to be ground is fixed on the fixture 12, and the lighting lamp 14 is turned on to illuminate the denture fixed on the fixture 12, providing sufficient light for the grinding work. The denture fixed on the fixture 12 is ground by the grinding machine 301. During the grinding process, the dust collection mechanism 9 is turned on, so that the main dust collection pipe 8 generates suction force. The main dust collection pipe 8 generates suction force in the manifold box 6, and the manifold box 6 generates suction force in multiple dust collection branch pipes 5. The multiple dust collection branch pipes 5 generate a relatively uniform suction force in the dust collection hood 4. The dust collection hood 4, which is set with one end extending outward, generates suction force when grinding the grinding head at one end of the grinding machine 301. Debris is sucked up and drawn into the vacuuming mechanism 9 through the suction branch pipe 5 and the manifold box 6 in conjunction with the suction main pipe 8. When the position of the light 14 needs to be adjusted, the locking screw 15 is rotated to release one end of the locking screw 15 from the top of the connecting ring 1301. The connecting sleeve 1302 slides on the outer surface of the middle part of the connecting ring 1301 to adjust the position of the light 14. After the adjustment is completed, the locking screw 15 is rotated again to make one end of the locking screw 15 abut against the top of the connecting ring 1301, fixing the position of the connecting sleeve 1302 on the connecting ring 1301 and fixing the position of the light 14.
