[0002] Tooth polishing is one of the steps in dental treatment. Usually, when a tooth is damaged, it needs to be extracted and a denture is installed to ensure aesthetics and functionality. The denture is usually polished manually. The materials for dentures are usually resin, metal alloy, pure titanium, and all-ceramic. Because resin dentures are inexpensive, they are often used as temporary dentures or for patients with limited financial resources, so the demand is relatively large. Currently, when polishing existing resin teeth, the polishing is usually done directly at the polishing station. During the polishing process, debris flies everywhere, making the cleaning of the fallen debris tedious and causing great trouble for medical staff after polishing. Summary of the Invention

[0006] Preferably, the cleaning mechanism includes a cleaning rod, a cleaning rod is provided on one side of the filter screen working plate, a first motor is installed at one end of the housing, the output end of the first motor is fixedly connected to a first threaded rod connected to the inside of the housing through a bearing, one end of the cleaning rod is connected to the first threaded rod through a thread, and the other end of the cleaning rod is slidably connected to a guide rod fixedly connected to the inner wall of the housing, which can automatically clean the waste debris on the surface of the filter screen working plate.

[0007] Preferably, the control terminal of the first motor is electrically connected to the control panel, which facilitates user control of the device.

[0008] Preferably, the filtration mechanism includes a filter chamber, with the filter chamber located at the top of the filter box. Limiting rods are symmetrically fixedly connected to the inner wall of the bottom of the filter chamber. A filter box is slidably connected to one side of the filter chamber. Magnetic handles that attract the surface of the filter box are symmetrically fixedly connected to one side of the filter box. A filter element is installed inside the filter box, with the top of the filter element slidably connected to the top of the filter box. Two sets of filter plates are fixedly connected to the middle of the filter element, with the ends of the filter plates close to each other separated from the inner wall of the filter element. A collection box is fixedly connected to the inner wall of one side of the filter chamber. Suction holes are evenly distributed on one side of the filter box. Suction tubes that are slidably connected to the suction holes are evenly connected to one side of the collection box. A suction tube is fixedly connected to one side of the filter box, with the top of the suction tube located at the top of the filter element and the bottom of the suction tube located at the bottom of the box, facilitating the filtration of airborne debris.

[0009] Preferably, the power mechanism includes a suction chamber, which is located at the bottom of the filter box. An air pump is installed inside the suction chamber. The input end of the air pump is connected to a bent pipe connected to the bottom of the collection box. The output end of the air pump is connected to an air collecting hopper. A circulation pipe is fixedly connected to the inner wall of the bottom of the box, with one side of the circulation pipe located inside the suction chamber. Three sets of air vents are provided on the surface of the circulation pipe, with the vents positioned at the surface of the inner wall of the bottom of the box. A connecting pipe connected to the air collecting hopper is located on one side of the circulation pipe. An exhaust pipe is connected to one end of the air collecting hopper, and one end of the exhaust pipe is flush with the outer wall of the filter box. A control block is provided on one side of the air pump. The control block has two sets of sliding grooves inside. The middle parts of the external exhaust pipe and the connecting pipe are respectively connected to the sliding grooves. A sealing block is slidably connected inside the limiting rod. A second motor is installed at one end of the control block. The output end of the second motor is fixedly connected to a second threaded rod. One end of the second threaded rod is connected to the control block through a bearing. The second threaded rod is connected to the sealing block through a thread. Both sets of sealing blocks are located on the same side of the sliding groove. One set of sealing blocks blocks the connecting pipe, while the other set of sealing blocks does not block the track. This provides suction and controls the air pressure inside the box, keeping the box in a negative pressure state and facilitating the collection of waste.

[0010] Preferably, one end of the external discharge pipe is equipped with an electromagnetic three-way valve, and one end of the electromagnetic three-way valve extends through the filter box into the interior of the box. A hook for hanging the air-flushing pipe is fixedly connected to the inner wall of one side of the box. One end of the air-flushing pipe is connected to a blower, which facilitates the user to clean the polishing tools and clean the inner wall of the box.

[0011] Preferably, the control terminals of the electromagnetic three-way valve, the second motor, and the suction pump are all electrically connected to the control panel, which facilitates user control of the device. The air collecting hopper is funnel-shaped to increase the airflow pressure.

[0012] The operating method of this device is as follows: Step 1: The user places the resin dentures and polishing tools on the surface of the filter screen work plate; Step 2: Turn on the suction. One end of the suction pump generates suction. At this time, the air inside the chamber enters the filter through the suction tube. It is partially blocked by the filter plate baffle inside the filter and finally filtered through the lower part of the filter. The filtered air is then sucked away by the suction pump through the suction tube, the collection box and the bend. Step 3: Adjust the negative pressure of the chamber. The output end of the second motor causes the sealing block to slide inside the sliding groove through the second threaded rod. The sliding groove blocks the area of ​​the connecting pipe and the external exhaust pipe, controlling the amount of air blown out by the suction pump into the chamber through the connecting pipe and the circulation pipe. It can also control the amount of air blown out by the suction pump through the external exhaust pipe. The user can control the opening degree of the connecting pipe and the external exhaust pipe according to their needs and set the negative pressure intensity inside the chamber. Step 4: Grinding. The user inserts their arm through the negative pressure perforation into the inside of the chamber and grinds the dentures with tools. The debris falling through the filter screen and working plate can be blown away by the air vent. The air vent can also blow the debris that falls on the inner wall at the bottom of the chamber towards the bottom of the suction tube. Step 5: Clean dentures and tools. The user controls the second motor and solenoid three-way valve through the control panel to allow air to enter the air inlet pipe. The air inside the air inlet pipe is finally blown out through the air gun. The user can use the air gun to clean the polished dentures and polishing tools. At the same time, the output end of the first motor drives the first threaded rod to rotate, and the cleaning rod cleans all the debris on the surface of the filter screen working plate. Step Six: Final Cleaning. Finally, fully open the connecting pipe to allow the air inside the chamber to circulate completely, thereby cleaning out the debris inside the chamber. By pulling the magnetic handle, you can remove the filter box and filter element. Pull the filter element upwards out of the filter box and pour out the debris inside the filter element.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The user controls the device via the control panel. The user places the resin dentures and polishing tools on the surface of the filter plate and controls the suction pump via the control panel. The suction pump generates suction, drawing air from inside the chamber into the filter element through the suction pipe. The air is partially blocked by the filter plate baffles inside the filter element and finally filtered through the lower part of the filter element. The filtered air is then drawn away by the suction pump through the suction pipe, collection box, and bend. The suction pump generates a blowing force, expelling the filtered air. The airflow is amplified by the air collection duct. The expelled air is then discharged from the device through the exhaust pipe, with no recirculated air entering the chamber. At this point, the negative pressure inside the chamber is maximized. The user then controls the... The two motors operate, controlling the negative pressure inside the chamber. The output of the second motor, via a second threaded rod, causes the sealing block to slide within the sliding groove. This sliding groove blocks the area of ​​the connecting pipe and the external exhaust pipe, controlling the amount of air blown by the suction pump into the chamber through the connecting and circulation pipes, and also controlling the amount of air expelled through the external exhaust pipe. Users can control the two sets of sealing blocks to partially block the connecting and external exhaust pipes respectively. In this state, half of the air inside the chamber circulates internally, and the other half is expelled externally, maintaining a negative pressure within the chamber. Outside air flows into the chamber through the negative pressure perforations, preventing debris from flying out and ensuring that debris remains within the chamber, facilitating cleaning. The air inside the circulation pipe... Air is blown out through the vents. During grinding, debris that falls through the filter screen and onto the work plate is blown away by the vents. The vents also blow debris that falls onto the inner wall of the bottom of the housing towards the bottom of the suction pipe, facilitating debris collection. After grinding, the user controls the second motor via the control panel, causing a set of sealing blocks to block most of the connecting pipe. At this point, most of the air enters the exhaust pipe. The user then controls the solenoid three-way valve to activate the air flushing pipe, preventing further exhaust. The air inside the flushing pipe is finally blown out through the air gun. The user can use the air gun to clean the ground teeth and grinding tools. Simultaneously, the output of the first motor drives the first threaded rod to rotate, which is guided by the guide rod, allowing the cleaning process to proceed smoothly. The cleaning rod removes all debris from the surface of the filter screen working plate. Finally, the connecting pipe is fully opened to allow the air inside the chamber to circulate completely, thus cleaning the debris inside the chamber. If there is still debris inside the chamber, the user can open the tilted cover, remove the filter screen working plate, and finally clean the inner wall at the bottom of the chamber. The user can remove the filter box and filter element by pulling the magnetic handle. The user can then pull the filter element upwards out of the filter box and empty the debris inside the filter element. This device allows the dental grinding to be carried out in a specific negative pressure automatic cleaning environment, eliminating concerns about the debris generated during grinding flying everywhere, thus reducing the user's workload by eliminating the need for lengthy cleaning.

One end of the cleaning rod 8 is connected to the first threaded rod 10 through a thread. The other end of the cleaning rod 8 is slidably connected to a guide rod 9 fixedly connected to the inner wall of the housing 1. The output end of the first motor 11 drives the first threaded rod 10 to rotate and is guided by the guide rod 9. At this time, the cleaning rod 8 can clean all the waste on the surface of the filter screen working plate 6, and can automatically clean the waste on the surface of the filter screen working plate 6. Please see Figure 5 and Figure 6In this embodiment, the filtration mechanism includes a filter chamber 12. A filter chamber 12 is formed at the top of the filter box 2. Limiting rods 24 are symmetrically fixedly connected to the inner wall of the bottom of the filter chamber 12. A filter box 15 is slidably connected to one side of the filter chamber 12. Magnetic handles 16 that attract the surface of the filter box 2 are symmetrically fixedly connected to one side of the filter box 15. A filter element 17 is disposed inside the filter box 15, and the top of the filter element 17 is slidably connected to the top of the filter box 15. Two sets of filter plate baffles 18 are fixedly connected to the middle of the filter element 17, and the ends of the filter plate baffles 18 that are close to each other are separated from the inner wall of the filter element 17. A collection box 20 is fixedly connected to one inner wall of the filter chamber 12. Suction holes 21 are evenly formed on one side of the filter box 15. Suction tubes 22 that are slidably connected to the suction holes 21 are evenly connected to one side of the collection box 20. A suction tube 19 is fixedly connected to one side of the filter box 2. The top of the suction pipe 19 is located at the top of the filter element 17, which facilitates the intake of air and waste into the filter element 17. The bottom of the suction pipe 19 is located at the bottom of the box 1, which facilitates the intake of air and waste inside the box 1 through the suction pipe 19. One end of the suction pump 14 generates suction. At this time, the air inside the box 1 enters the filter element 17 through the suction pipe 19. It is partially blocked by the filter plate baffle 18 inside the filter element 17. Then the air will flow according to the setting of the filter plate baffle 18, thereby increasing the filtration time. Finally, it is filtered through the lower part of the filter element 17. The filtered air enters the collection box 20 through the suction pipe 22, and then enters the bend pipe 23 through the collection box 20. Finally, it is sucked away by the suction pump 14 through the bend pipe 23. At this time, one end of the suction pump 14 generates blowing force to blow out the filtered air, which facilitates the filtration of the air in the box 1. Please see Figures 5-8In this embodiment, the power mechanism includes a suction chamber 13. The bottom of the filter box 2 has a suction chamber 13. An air pump 14 is installed inside the suction chamber 13. The input end of the air pump 14 is connected to a bent pipe 23 connected to the bottom of the collection box 20. The output end of the air pump 14 is connected to a collecting hopper 25. A circulation pipe 26 is fixedly connected to the inner wall of the bottom of the box 1, and one side of the circulation pipe 26 is located inside the suction chamber 13. Three sets of air vents 40 are opened on the surface of the circulation pipe 26, and the height of the air vents 40 is located on the surface of the inner wall of the bottom of the box 1. One side of the circulation pipe 26 is connected to a connecting pipe 27 connected to the collecting hopper 25. One end of the collecting hopper 25 is connected to an external exhaust pipe 28, and one end of the external exhaust pipe 28 is flush with the outer wall of the filter box 2. The air pump 14... A control block 33 is provided on one side of the 4. The control block 33 has two sets of sliding grooves 34 inside. The middle parts of the external exhaust pipe 28 and the connecting pipe 27 are respectively connected to the sliding grooves 34. A sealing block 36 is slidably connected inside the limit rod 24. A second motor 35 is installed at one end of the control block 33. A second threaded rod 37 is fixedly connected to the output end of the second motor 35, and one end of the second threaded rod 37 is connected to the control block 33 via a bearing. The second threaded rod 37 is connected to the sealing block 36 via threads. Both sets of sealing blocks 36 are located on the same side of the sliding grooves 34. One set of sealing blocks 36 blocks the connecting pipe 27, while the other set of sealing blocks 36 does not block the track 38. The airflow from the suction pump 14 can be increased through the air collecting hopper 25. The exhaust air is discharged from the device through the external exhaust pipe 28. No recirculated air enters the housing 1, and the negative pressure generated in the housing 1 is maximized. The user can control the negative pressure state inside the housing 1 by controlling the operation of the second motor 35. After the second motor 35 starts working, the output end of the second motor 35 drives the second threaded rod 37 to rotate. The rotation of the second threaded rod 37 allows the sealing block 36 to slide inside the sliding groove 34. At this time, the sliding groove 34 blocks the area of ​​the connecting pipe 27 and the external exhaust pipe 28, which can control the amount of air blown out by the suction pump 14 into the housing 1 through the connecting pipe 27 and the circulation pipe 26, and can also control the amount of air blown out by the suction pump 14 and discharged through the external exhaust pipe 28. The user can control the two sets of sealing blocks 36 to respectively block the connecting pipe 27 and the external exhaust pipe 28. With the external exhaust pipe 28 partially blocked, half of the air inside the housing 1 is internally circulated while the other half is exhausted externally. Housing 1 is also under negative pressure. Outside air flows into housing 1 through the negative pressure perforation 4, ensuring consistent air pressure inside and outside housing 1. This prevents debris from flying out and ensures that debris remains inside housing 1, facilitating cleaning. Air inside the circulation pipe 26 is blown out through the vents 40. Users can adjust the negative pressure intensity according to their needs. During grinding, debris falling through the filter screen 6 is effectively blown away because the circulation pipe 26 has three vents 40 on its inner side, and the vents 40 are slightly higher than the inner wall of the bottom of housing 1. Furthermore, the two ends of the inner wall of the bottom of housing 1 are sloped.The air vent 40 can also blow debris that falls onto the inner wall of the bottom of the housing 1 towards the bottom of the suction pipe 19, facilitating the collection of debris. This debris then enters the internal air circulation, filtering it and providing suction. Simultaneously, it controls the air pressure inside the housing 1, keeping it in a negative pressure state, which also facilitates the collection of debris. It should be noted that the lower middle part of the inclined cover 3 has symmetrical negative pressure perforations 4, which facilitates the user's hand to reach into the box 1. The control terminal of the control panel 5 is electrically connected to an external power source, which facilitates the user to control the operation of this device. A track 38 is fixedly connected to the inner wall of the top of the box 1. A slider hook 39 is evenly slidably connected to one end of the track 38, which facilitates the user to hang grinding tools. The two sides of the bottom of the box 1 are sloped, which facilitates the centralized processing of waste chips. The control terminal of the first motor 11 is electrically connected to the control panel 5, which facilitates the user to control the operation of this device. The external exhaust pipe 28 is equipped with an electromagnetic three-way valve 29 at one end, and one end of the electromagnetic three-way valve 29 extends through the filter box 2 into the interior of the box 1. A hook 31 for hanging the air-purifying pipe 30 is fixedly connected to the inner wall of one side of the box 1. One end of the air-purifying pipe 30 is connected to a blower 32, which makes it convenient for users to clean the polishing tools and clean the inner wall of the box 1. The control terminals of the electromagnetic three-way valve 29, the second motor 35 and the air pump 14 are all electrically connected to the control panel 5, which makes it convenient for users to control the operation of this device. The air collecting hopper 25 is trumpet-shaped to increase the air pressure. The device operates as follows: Step 1: The user places the resin dentures and polishing tools on the surface of the filter screen working plate 6; Step 2: Turn on the suction. One end of the suction pump 14 generates suction. At this time, the air inside the box 1 enters the filter element 17 through the suction pipe 19. It is partially blocked by the filter plate baffle 18 inside the filter element 17 and finally filtered through the lower part of the filter element 17. The filtered air is sucked away by the suction pump 14 through the suction pipe 22, the collection box 20 and the bend pipe 23. Step 3: Adjust the negative pressure of the box 1. The output end of the second motor 35 causes the sealing block 36 to slide inside the sliding groove 34 through the second threaded rod 37. The sliding groove 34 blocks the area of ​​the connecting pipe 27 and the external exhaust pipe 28, controlling the amount of air blown out by the suction pump 14 into the box 1 through the connecting pipe 27 and the circulation pipe 26. It can also control the amount of air blown out by the suction pump 14 through the external exhaust pipe 28. The user can control the opening degree of the connecting pipe 27 and the external exhaust pipe 28 according to the needs and set the negative pressure intensity inside the box 1. Step 4: Grinding. The user inserts their arm through the negative pressure perforation 4 into the inside of the housing 1 and grinds the dentures with tools. The debris falling through the filter screen working plate 6 can be blown away by the air vent 40. The air vent 40 can also blow the debris that falls on the bottom inner wall of the housing 1 towards the bottom of the suction pipe 19. Step 5: Clean dentures and tools. The user controls the second motor 35 and the solenoid three-way valve 29 through the control panel 5 to allow air to enter the air inlet pipe 30. The air inside the air inlet pipe 30 is finally blown out through the blow gun 32. The user can use the blow gun 32 to clean the polished teeth and polishing tools. At the same time, the output end of the first motor 11 drives the first threaded rod 10 to rotate, and the cleaning rod 8 cleans all the debris on the surface of the filter screen working plate 6. Step Six: Final Cleaning. Finally, fully open the connecting pipe 27 to allow the air inside the housing 1 to circulate completely, thereby cleaning the debris inside the housing 1. By pulling the magnetic handle 16, the filter box 15 and filter element 17 can be removed. Pull the filter element 17 upwards out of the filter box 15 and pour out the debris inside the filter element 17.

[0018] Working Principle: The user controls the device via control panel 5. The user places the resin dentures and polishing tools on the surface of the filter plate 6. Controlling the air pump 14 via control panel 5 generates suction. Air from inside the housing 1 enters the filter element 17 through suction pipe 19. The air is partially blocked by the filter plate baffle 18 inside the filter element 17, causing the air to flow according to the baffle 18's design, thus increasing the filtration time. Finally, the air is filtered through the lower part of the filter element 17. The filtered air then enters the collection box 20 through suction pipe 22, then through the collection box 20 into the bend pipe 23, and finally is drawn away by the air pump 14 through the bend pipe 23. At this time, one end of the air pump 14 generates blowing force. The filtered air is blown out, and the airflow from the suction pump 14 is amplified by the air collecting hopper 25. The blown air is then discharged from the device through the exhaust pipe 28, with no recirculated air entering the housing 1. The negative pressure in the housing 1 is maximized. The user can control the negative pressure inside the housing 1 by controlling the second motor 35. After the second motor 35 starts working, its output drives the second threaded rod 37 to rotate. The rotating threaded rod 37 causes the sealing block 36 to slide inside the sliding groove 34. The sliding groove 34 blocks the area of ​​the connecting pipe 27 and the exhaust pipe 28, thus controlling the amount of air blown out by the suction pump 14 that enters the housing 1 through the connecting pipe 27 and the circulation pipe 26. This also controls the amount of air blown out by the suction pump 14. The amount of air discharged through the exhaust pipe 28 can be controlled by the user to partially block the connecting pipe 27 and the exhaust pipe 28 with two sets of sealing blocks 36 respectively. At this time, half of the air inside the box 1 is internally circulated and the other half is discharged outwards. The box 1 is also in a negative pressure state. Outside air flows into the box 1 through the negative pressure perforation 4 to ensure the consistency of air pressure inside and outside the box 1, thereby preventing waste from flying outwards and ensuring that the waste remains inside the box 1, which is convenient for the user's cleaning work. The air inside the circulation pipe 26 is blown out through the air outlet 40. The user can set the intensity of the negative pressure state according to the usage requirements. The user can put their arm through the negative pressure perforation 4 and insert it into the inside of the box 1 to carry out the grinding work. When the user grinds, the waste falling through the filter screen working plate 6 is due to Three sets of air vents 40 are provided on the inner side of the circulation pipe 26. The height of the air vents 40 is slightly higher than the inner wall of the bottom end of the box 1, and the two ends of the inner wall of the bottom end of the box 1 are sloped, so that the waste debris can be blown away more effectively. The air vents 40 can also blow the waste debris that falls on the inner wall of the bottom end of the box 1 towards the bottom end of the suction pipe 19, which facilitates the collection of waste debris. Finally, the waste debris enters the internal air circulation, thereby filtering the waste debris. After the user finishes polishing, the user controls the second motor 35 through the control panel 5, so that a set of sealing blocks 36 blocks most of the connecting pipe 27. At this time, most of the air enters the exhaust pipe 28. Then, the user controls the solenoid three-way valve 29 to work, so that the air enters the air flushing pipe 30 and is no longer discharged. The air inside the air flushing pipe 30 is finally blown out by the blower 32.The user can use the air gun 32 to clean the polished teeth and polishing tools by blowing away the debris adhering to their surfaces. Simultaneously, the output of the first motor 11 drives the first threaded rod 10 to rotate, which is guided by the guide rod 9. This allows the cleaning rod 8 to completely clean the debris from the surface of the filter screen working plate 6. Finally, the connecting pipe 27 is fully opened to allow complete internal air circulation within the housing 1, thus cleaning the debris inside the housing 1. If there is still debris inside the housing 1, the user can open the tilting cover 3, remove the filter screen working plate 6, and finally clean the debris on the inner wall at the bottom of the housing 1 to the bottom of the suction pipe 19 to remove it. After cleaning, the user resets the filter screen working plate 6. At this point, the four corners of the bottom of the filter screen working plate 6 engage with the support block 7, thus limiting and supporting the filter screen working plate 6. The user can remove the filter box 15 and filter element 17 by pulling the magnetic handle 16. The user then pulls the filter element 17 upwards out of the filter box 15, inverts it, and shakes it left and right to empty the waste. Finally, the user puts the filter element 17 back into the filter box 15, where its top engages with the top of the filter box 15. The user then places the filter box 15 into the filter chamber 12, where the limiting rod 24 positions it until the suction tube 22 is inserted into the suction hole 21. The magnetic handle 16 at one end of the filter box 15 attracts the outer wall of the filter chamber 2. The installation is now complete. This device creates a specific negative pressure environment for automatic cleaning during dental grinding, eliminating concerns about grinding debris flying everywhere and reducing the user's workload by saving them time and effort.
