Description

Technical Field

[0001] The present invention relates to the technical field of oral cleaning, and more particularly to a tooth repairing polisher. Background Art

[0002] A tooth repair grinder is a tool used in oral medicine, mainly used for repairing, grinding and trimming teeth. A tooth repair grinder is usually driven by an electric motor and contacts and processes the tooth surface through a high-speed rotating grinding head. It can effectively remove stains, tartar, carious tissue, etc. on the tooth surface without causing excessive damage to healthy tooth tissue.

[0003] Due to the characteristics of the tooth arrangement structure and the relatively limited space inside the oral cavity, when using a grinder to grind the tooth surface, especially the inner teeth, the grinder uses a linear feed and direct processing grinding method, which limits the flexibility of operation when operating on the inner teeth of the oral cavity. In this case, the grinder is difficult to effectively adapt to the complex and compact space inside the oral cavity, resulting in a significant increase in the difficulty of operation and inconvenience in the operation process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) In this solution, due to the support of the flexible push block, the third rotating shaft can maintain a tilted posture, and through the cooperation of the spherical part and the connecting seat, it is ensured that the third rotating shaft maintains a tilted state while maintaining flexible rotation ability, so that the tilted grinding head can smoothly reach and effectively grind the inner area of ​​the tooth, thereby improving the overall flexibility and accuracy of the tooth grinding operation.

[0018] (2) In the tooth grinding operation, the push button is manually pushed down to drive the push rod to push the ball downward, thereby realizing the transmission of thrust and causing the push seat to squeeze the roller, thereby causing multiple flexible push blocks to expand radially outward, increasing the deflection angle of the grinding head, thereby allowing for greater flexibility in adjustment of the advancement amplitude of the push button during the tooth grinding process, significantly enhancing the adaptability and accuracy of the grinding operation, and further improving the flexibility and efficiency of tooth grinding.

[0019] (3) In the process of pushing the push button upward, the present invention no longer applies pressure to the ball.

By adjusting the pushing amplitude of the push button, the deflection angle of the connecting seat and the grinding head it carries can be dynamically and immediately reduced, thereby further ensuring the flexibility and accuracy of the operation.

[0020] (4) In this solution, during the movement of the push button, the resistance generated by the close contact between the block and the wave plate can effectively control the position of the push button. When the user is grinding at a specific angle, there is no need to continuously apply external force to maintain the specific position of the push button, thereby maintaining the required deflection angle of the grinding head.

[0021] (5) The present solution can effectively shield and block the debris generated during the grinding operation through the folding plate, preventing it from entering the interior of the outer shell, especially preventing the debris from accumulating in the joint area between the spherical member and the connecting seat, so as to ensure the flexibility of the grinding head during the deflection and rotation process. In addition, the folding plate adapts to the deflection action of the third rotating shaft, and can automatically fold and compress when the third rotating shaft is deflected, thereby ensuring that there is no obstruction to the deflection operation of the third rotating shaft, and maintaining the smoothness and accuracy of the operation.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 6 A tooth repairing grinder comprises a grinder body 1 and a grinding head 2, a bending mechanism, wherein the bending mechanism is arranged at the bottom end of the grinder body 1, the bending mechanism comprises a fourth rotating shaft 310 rotatably connected to the bottom end of the grinder body 1, the lower end of the fourth rotating shaft 310 is fixedly connected to a first transmission gear 302, the left side of the arc surface at the lower end of the grinder body 1 is rotatably connected to a second rotating shaft 308, the bottom end of the second rotating shaft 308 is fixedly connected to a rotating seat 312, the middle section of the outer surface of the second rotating shaft 308 is fixedly connected to a second transmission gear 307, the rotating seat 312 A connecting rod 313 is inserted into the arc surface, and the number of the connecting rods 313 is multiple and they form a group of two. A flexible push block 311 is fixedly connected between the ends of the two adjacent connecting rods 313 away from the rotating seat 312. When the circle formed by the multiple flexible push blocks 311 rotates, the connecting seat 306 will be driven to rotate. Since the surface of the flexible push blocks 311 has a certain deformability, when the multiple flexible push blocks 311 expand or gather, the side walls of the flexible push blocks 311 can fit together to reduce the gap between the flexible push blocks 311, thereby reducing the vibration generated when the connecting seat 306 is driven to rotate.

[0036] The first suspension bracket 303 is fixedly connected to the right side of the arc surface at the lower end of the grinder body 1, and the first rotating shaft 304 is fixedly connected to the bottom end of the first suspension bracket 303. The bottom end of the first rotating shaft 304 is fixedly connected to a spherical member 305. The outer surface of the spherical member 305 is sleeved with a connecting seat 306. The bottom end of the connecting seat 306 is fixedly connected to a third rotating shaft 309. The third rotating shaft 309 can be flexibly rotated without affecting its deflection through the cooperation of the spherical member 305 and the connecting seat 306. The grinding head 2 and the third rotating shaft 309 The bottom end of the grinder body 1 is fixedly connected, so that the inner side of the tooth can be polished by the inclined grinding head 2. The first transmission gear 302 is meshed with the second transmission gear 307. The lower end of the grinder body 1 is fixedly connected with an outer shell 301. The outer shell 301 can reduce the exposure of components, improve the aesthetics and safety during use. A strip hole 610 is provided at the bottom of the outer shell 301, so that the third rotating shaft 309 can only rotate in one direction but cannot rotate to both sides. The third rotating shaft 309 is inserted into the strip hole 610.

[0037] Among them, the second suspension frame 315 is rotatably connected to the right side of the bottom end of the first suspension frame 303, and the bottom end of the second suspension frame 315 is fixedly connected to a connecting frame 319, and a roller 316 is rotatably connected between the two lateral arm ends of the connecting frame 319. The roller 316 can reduce the friction resistance encountered by the connecting seat 306 during rotation, and a suspension plate 318 is fixedly connected to the middle part of the bottom end of the first suspension frame 303, and a second spring 317 is fixedly connected between the suspension plate 318 and the second suspension frame 315. The rotating seat 312 can be supported by the second spring 317 to avoid swinging of the connecting seat 306 during rotation and affecting the stability of use, and when the connecting seat 306 is not supported, the connecting seat 306 can be pushed back to the center.

[0038] By adopting the above technical solution, the fourth rotating shaft 310 is connected to the electric motor inside the grinder body 1. The lithium battery inside the grinder body 1 provides energy for the electric motor. The electric motor provides power to drive the fourth rotating shaft 310 to rotate, thereby driving the first transmission gear 302 and the second transmission gear 307 to rotate. During the rotation of the second transmission gear 307, the second rotating shaft 308 and the rotating seat 312 will be driven to rotate, thereby driving the circular rotation composed of the multiple flexible push blocks 311, and the flexible push blocks 311 are in contact with the surface of the connecting seat 306. Therefore, when the circle formed by the multiple flexible push blocks 311 rotates, the connecting seat 306 will be driven to rotate, thereby driving the third rotating shaft 309 and the grinding head 2 to rotate, so that the teeth can be polished through the grinding head 2, and because of the support of the flexible push block 311, the third rotating shaft 309 can be in a deflected state, and through the cooperation of the spherical part 305 and the connecting seat 306, the third rotating shaft 309 can be flexibly rotated without affecting its deflection, and the deflected grinding head 2 can be used to grind the inner side of the tooth, thereby improving the flexibility of the tooth grinding process.

[0039] like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, a control mechanism is arranged inside and at the bottom of the grinder body 1, and the control mechanism includes a conveying tube 404 fixedly inserted inside the grinder body 1, and a ball 402 is arranged inside the conveying tube 404, and the number of the balls 402 is multiple, and force transmission can be achieved by pushing multiple balls 402, and the inner arc surface of the outer shell 301 is fixedly connected to the third suspension bracket 403, and the surface of the third suspension bracket 403 is movably sleeved with a pushing seat 401, and the roller 406 is squeezed by the pushing seat 401, so that the multiple flexible push blocks 311 can be moved in a direction away from each other, that is, the flexible push blocks 311 can be controlled to push the connecting seat 306 and the grinding head 2 to increase the deflection angle, and the lower end of the conveying tube 404 and the top inner wall of the pushing seat 401 are inserted through.

[0040] Among them, a push rod 412 is inserted into the inner top end of the conveying tube 404, and the cross-sectional shape of the push rod 412 is "L"-shaped. The lateral arm end of the push rod 412 is fixedly connected with a push button 411, and the outer surface of the lower end of the conveying tube 404 is fixedly sleeved with a fixed ring 409. The inner top end of the push seat 401 is fixedly connected with a fourth suspension bracket 410, and the bottom end of the fourth suspension bracket 410 is fixedly connected with a support plate 407, and a third spring 408 is fixedly connected between the support plate 407 and the fixed ring 409. When no pressure is applied to the ball 402, the third spring 408 will drive the ball 402 to move upward, so that the ball 402 at the uppermost end is always in contact with the bottom end of the push rod 412, so as to facilitate the next push of the push button 411.

[0041] Among them, the surface of the connecting rod 313 located at the top is fixedly connected to the vertical rod 405, and the top of the vertical rod 405 is rotatably connected to the roller 406. The roller 406 can reduce the friction resistance and avoid excessive wear when the push seat 401 rotates. The first spring 314 is fixedly connected between the flexible push block 311 and the rotating seat 312. When no pressure is applied to the ball 402, the first spring 314 can pull multiple flexible push blocks 311 to move in a direction close to each other, thereby reducing the connection seat 306 and the grinding head. 2, the lower surface of the horizontal arm end of the push rod 412 is fixedly connected with a wave plate 501, and the interior of the grinder body 1 is fixedly connected with an elastic plate 502, and the elastic plate 502 can make the block 503 fit the wave plate 501. There are two elastic plates 502 and they are respectively located on both sides of the wave plate 501. The bottom end of the elastic plate 502 is fixedly connected with a block 503 adapted to the wave plate 501. The resistance generated when the block 503 fits the wave plate 501 can limit the movement of the push button 411.

[0042] By adopting the above technical solution, during the process of grinding the teeth, the push button 411 is pushed downward to insert the push rod 412 into the delivery tube 404. During this process, the multiple balls 402 can be pushed to move downward along the path of the delivery tube 404, so as to realize the transmission of force. During the downward movement of the balls 402, the support plate 407 and the fourth suspension bracket 410 will be pushed downward synchronously, thereby driving the pushing seat 401 to move downward, and the roller 406 is squeezed by the pushing seat 401, so that the multiple rollers 406 drive the multiple flexible push blocks 311 to move away from each other, so that the flexible push blocks 311 can be controlled to push the connecting seat 306 and the grinding head 2 to increase the deflection angle, thereby improving the flexibility in the process of grinding the teeth.

[0043] Since the first spring 314 is always in a stretched state, when the push button 411 is pushed upward, the pressure applied to the ball 402 is released, and the first spring 314 can pull the multiple flexible push blocks 311 to move toward each other, thereby reducing the deflection angle of the connecting seat 306 and the grinding head 2. Similarly, the third spring 408 at this time will also drive the support plate 407 to be lifted, and during the lifting process of the support plate 407, the ball 402 can be pushed to move upward, so that the ball 402 at the uppermost end is always in contact with the bottom end of the push rod 412, so as to facilitate the next push of the push button 411, and avoid the situation in which the vibration ball 402 collides with the conveying tube 404 during grinding and affects the grinding operation. Since the block 503 fits the wave plate 501 and the elastic plate 502 is elastic, the resistance generated when the block 503 fits the wave plate 501 during the process of pushing the push button 411 can limit the movement of the push button 411. When the user performs grinding at a specific angle, there is no need to keep pushing the push button 411 to maintain the deflection angle of the grinding head 2, thereby increasing the selectivity and operational portability during use.

[0044] like Fig.10 As shown, a bar frame 602 is fixedly connected to the lower surface of the outer shell 301, and the bar frame 602 is communicated with the bar hole 610. Arc grooves 603 are opened at the front and back inside the bar frame 602. A connecting piece 609 is slidably connected between the two arc grooves 603. The third rotating shaft 309 is inserted through the inside of the connecting piece 609. The left and right ends of the connecting piece 609 are fixedly connected with folding plates 601. The ends of the two folding plates 601 away from each other are respectively fixedly connected to the left and right sides of the inside of the bar frame 602. The folding plates 601 can block the debris generated during the grinding process to prevent the debris from entering the outer shell 301.

[0045] Among them, a bracket 607 is fixedly connected to the left side of the interior of the bar frame 602, and a fan blade 606 is rotatably connected to the middle part of the bracket 607. The rotating fan blade 606 can be used to discharge water vapor that passes through the folding plate 601 in real time to prevent water vapor from being retained in the outer shell 301 and affecting the sanitary conditions during use. The fan blade 606 is fixedly connected to a fifth rotating shaft 608 on one side away from the bracket 607, and the end of the fifth rotating shaft 608 away from the bracket 607 is fixedly connected to a second bevel gear 605, and the arc surface of the third rotating shaft 309 is fixedly connected to a first bevel gear 604, and the first bevel gear 604 is meshed with the second bevel gear 605.

[0046] By adopting the above technical solution, the folding plate 601 can block the debris generated during the grinding process, preventing the debris from entering the outer shell 301, especially the connection between the spherical member 305 and the connecting seat 306, and affecting the flexibility of the grinding head 2 to deflect and rotate, and the folding plate 601 is folded and compressed during the deflection of the third rotating shaft 309, so as not to affect the deflection operation of the third rotating shaft 309. Since the folding plate 601 cannot block the gas, during the rotation of the third rotating shaft 309, it will drive the first bevel gear 604 to rotate, and then drive the second bevel gear 605 to rotate while causing the fan blade 606 to rotate, so that the water vapor passing through the folding plate 601 can be discharged in real time through the rotating fan blade 606, so as to prevent the water vapor from being retained in the outer shell 301 and affecting the sanitary conditions during use.

[0047] Instructions for use: Use an electric motor to provide power to drive the fourth rotating shaft 310 to rotate, and then drive the first transmission gear 302 and the second transmission gear 307 to rotate. During the rotation of the second transmission gear 307, the second rotating shaft 308 and the rotating seat 312 will be driven to rotate, thereby driving the multiple flexible push blocks 311 to rotate, and driving the connecting seat 306 to rotate, thereby driving the third rotating shaft 309 and the grinding head 2 to rotate, so as to achieve grinding of teeth through the grinding head 2.

[0048] Pushing the push button 411 downward causes the push rod 412 to be inserted into the conveying tube 404, and pushes the multiple balls 402 to move downward along the path of the conveying tube 404. When the balls 402 move downward, they push the support plate 407 and the fourth suspension bracket 410 to move downward synchronously, thereby driving the pushing seat 401 to move downward. The pushing seat 401 squeezes the roller 406, causing the multiple rollers 406 to drive the multiple flexible push blocks 311 to move away from each other, thereby controlling the flexible push blocks 311 to push the connecting seat 306 and the grinding head 2 to increase the deflection angle.

[0049] The push button 411 is pushed upward to release the pressure on the ball 402 . At this time, the first spring 314 can pull the multiple flexible push blocks 311 to move toward each other, thereby reducing the deflection angle of the connecting seat 306 and the grinding head 2 .

[0050] The folding plate 601 can block the debris generated during the grinding process to prevent the debris from entering the outer shell 301, especially the connection between the spherical member 305 and the connecting seat 306. When the third rotating shaft 309 rotates, the first bevel gear 604 is driven to rotate, and then the second bevel gear 605 is driven to rotate, and the fan blade 606 is driven to rotate, so that the water vapor can be discharged in real time through the rotating fan blade 606.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
