Specific embodiments

[0019] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] As Figures 1 - 6 shown, a disinfection device for a dental handpiece used in oral medical devices includes a fixing plate 1. A support block 11 is fixedly connected to the left part of the top of the fixing plate 1. A collection tank 12 is fixedly connected to the right part of the top of the fixing plate 1. A disinfection box 13 is fixedly connected to the middle part of the top of the fixing plate 1. A magnetic attraction ring 14 is fixedly connected to the top of the disinfection box 13. A sealing cover 15 is inserted into the outer wall of the magnetic attraction ring 14. The bottom end of the sealing cover 15 abuts against the top of the disinfection box 13. A liquid outlet pipe 16 is fixedly connected to the bottom of the disinfection box 13. A valve is fixedly connected to the outer wall of the liquid outlet pipe 16. The right part of the liquid outlet pipe 16 is fixedly connected to the bottom of the collection tank 12. A drying mechanism 2 is fixedly connected to the top of the support block 11. A rotating mechanism 3 is fixedly connected to the top end of the inner cavity of the sealing cover 15. A fixing mechanism 4 is fixedly connected to the bottom end of the rotating mechanism 3. The drying mechanism 2 includes a blower 21. The bottom end of the blower 21 is fixedly connected to the top of the support block 11. The rotating mechanism 3 includes a fixed disk 31 and a first rotating rod 34. A fixed block 32 is fixedly connected to the top of the fixed disk 31. The top of the fixed block 32 is fixedly connected to the top end of the inner cavity of the sealing cover 15. The top of the first rotating rod 34 is slidably connected to the top of the fixed disk 31. The fixing mechanism 4 includes a fixing frame 41. The top of the fixing frame 41 is fixedly connected to the bottom end of the first rotating rod 34.

[0021] The dental handpiece 5 is fixed by the fixing mechanism 4. Subsequently, the sealing cover 15 is placed on the disinfection box 13. Then, the motor 17 can be started to drive the rotation mechanism 3 to rotate, and the rotation mechanism 3 drives the fixing mechanism 4 to rotate, thereby disinfecting the dental handpiece 5. After disinfection, the disinfected handpiece is dried by the drying mechanism 2.

[0022] As Figure 2 shown, a motor 17 is fixedly connected to the bottom end of the inner cavity of the disinfection box 13. The output end of the motor 17 is fixedly connected to a rotating shaft 18. The outer wall of the rotating shaft 18 is rotationally connected to the inner wall of the disinfection box 13. The top end of the rotating shaft 18 is fixedly connected to a clamping block 19, and the shape of the clamping block 19 is rectangular.

[0023] By picking up the sealing cover 15 and driving the fixed dental handpiece 5, the dental handpiece 5 is completely placed into the inner cavity of the disinfection box 13. At the same time, the inner wall of the positioning frame 36 is inserted into the outer wall of the clamping block 19, the outer wall of the fixed disk 31 is inserted into the top of the inner cavity of the disinfection box 13, and the outer wall of the sealing cover 15 is inserted into the inner wall of the magnetic attraction ring 14. The magnetic attraction ring 14 magnetically fixes the sealing cover 15, thereby covering the sealing cover 15 on the top of the disinfection box 13 to seal the inner cavity of the disinfection box 13. Then, the disinfection process can be started. By starting the motor 17, the rotating shaft 18 is driven to rotate, the rotating shaft 18 drives the clamping block 19 to rotate, and the clamping block 19 drives the turntable 35 to rotate synchronously.

[0024] As Figure 2 、 Figure 3 shown, the output end of the blower 21 is fixedly connected to a connecting pipe 22. The top of the connecting pipe 22 is fixedly connected to an annular pipe 23. The inner wall of the annular pipe 23 is fixedly connected with air outlet pipes 24 in a circular array. The outer wall of the air outlet pipes 24 is fixedly connected to the top of the disinfection box 13. The outer wall of the air outlet pipes 24 is fixedly connected with electromagnetic valves 25.

[0025] By opening the electromagnetic valve 25 and then starting the blower 21, the blower 21 conveys cold air or hot air through the connecting pipe 22. The conveyed air enters the annular pipe 23, and then the annular pipe 23 conveys the air into the air outlet pipes 24 respectively. The air is blown out by the air outlet pipes 24 to dry the dental handpiece 5, achieving the drying effect.

[0026] As Figure 2 、 Figure 4 shown, the teeth on the inner wall of the fixed disk 31 are engaged with a gear 33. The center of the gear 33 is fixedly connected to the top of a first rotating rod 34. The bottom of the outer wall of the first rotating rod 34 is rotationally connected to a turntable 35. The bottom end of the turntable 35 is fixedly connected to a positioning frame 36. The inner wall of the positioning frame 36 is inserted into the outer wall of the clamping block 19.

[0027] When the turntable 35 rotates, it drives the first rotating rod 34 to rotate. The first rotating rod 34 drives the gear 33 to rotate, causing the outer wall of the gear 33 to mesh with the teeth on the inner wall of the fixed disk 31, thereby enabling the gear 33 to rotate on its own axis. The gear 33 drives the first rotating rod 34 to rotate synchronously on its own axis. At the same time, the first rotating rod 34 drives the fixed frame 41 to rotate, and the fixed frame 41 drives the dental handpiece 5 to rotate. In this way, the dental handpiece 5 rotates around the center of the rotating shaft 18 while rotating on its own axis, enabling the dental handpiece 5 to better contact the disinfectant, accelerating the disinfection efficiency, and achieving the effect of accelerating the angular efficiency.

[0028] As Figure 2 , Figure 4 and Figure 5 shown, four guide wheels 37 are fixedly connected to the outer wall of the turntable 35 in a circular array. The outer wall of the guide wheel 37 is slidably connected to the inner wall of the fixed disk 31.

[0029] When the turntable 35 rotates, it drives the guide wheels 37 to slide synchronously on the inner wall of the fixed disk 31. The guide wheels 37 guide the turntable 35, making the rotation of the turntable 35 more stable.

[0030] As Figure 2 , Figure 6 shown, a second rotating rod 42 is rotatably connected to the inner wall of the fixed frame 41. A worm 43 is fixedly connected to the outer wall of the second rotating rod 42. A worm gear 44 meshes with the outer wall of the worm 43. Limiting rings 45 are fixedly connected to both the upper and lower ends of the worm gear 44. The outer wall of the limiting ring 45 is slidably connected to the inner wall of the fixed frame 41. Three convex blocks 46 are fixedly connected to the inner wall of the worm gear 44 in a circular array. The shape of the convex block 46 is arc-shaped.

[0031] By inserting the top of the dental handpiece 5 into the inner wall of the fixed frame 41, then rotating the second rotating rod 42 to drive the worm 43 to rotate, causing the worm 43 to mesh with the worm gear 44, thereby driving the worm gear 44 to rotate. The worm gear 44 drives the limiting ring 45 to rotate on the inner wall of the fixed frame 41. The limiting ring 45 limits the worm gear 44, making the rotation of the worm gear 44 more stable. At the same time, the worm gear 44 drives the convex blocks 46 to rotate.

[0032] As Figure 2 , Figure 6 shown, a pulley 47 is lapped on the outer wall of the convex block 46. The outer wall of the pulley 47 is rotatably connected to a mounting plate 48. A connecting rod 481 is fixedly connected to the outer wall of the mounting plate 48. The outer wall of the connecting rod 481 is slidably connected to the inner wall of the fixed frame 41. One end of the connecting rod 481 is fixedly connected to a clamping block 49. The outer wall of the clamping block 49 is lapped on the dental handpiece 5. The shape of the clamping block 49 is arc-shaped.

[0033] When the convex block 46 rotates, the outer wall of the convex block 46 contacts the pulley 47, so that the pulley 47 drives the mounting plate 48 to move. The mounting plate 48 drives the connecting rod 481 to slide on the inner wall of the fixed frame 41. The connecting rod 481 drives the clamping block 49 to move synchronously, so that the clamping block 49 tightly contacts the outer wall of the top of the dental handpiece 5, thereby fixing the dental handpiece 5 and preventing the dental handpiece 5 from falling off, achieving a fixing effect.

[0034] Working principle of the present invention: During use, pour the disinfectant into the inner cavity of the disinfection box 13, and then fix the dental handpiece 5 to be disinfected, so that the top of the dental handpiece 5 enters the inner wall of the fixing frame 41. Then rotate the second rotating rod 42 to drive the worm 43 to rotate, so that the worm 43 meshes with the worm wheel 44, thereby driving the worm wheel 44 to rotate. The worm wheel 44 drives the limiting ring 45 to rotate on the inner wall of the fixing frame 41. The limiting ring 45 limits the worm wheel 44, making the rotation of the worm wheel 44 more stable. At the same time, the worm wheel 44 drives the convex block 46 to rotate, so that the outer wall of the convex block 46 contacts the pulley 47. Thus, the pulley 47 drives the mounting plate 48 to move. The mounting plate 48 drives the connecting rod 481 to slide on the inner wall of the fixing frame 41. The connecting rod 481 drives the clamping block 49 to move synchronously, so that the clamping block 49 tightly contacts the outer wall of the top of the dental handpiece 5, thereby fixing the dental handpiece 5 and preventing the dental handpiece 5 from falling off, achieving a fixing effect. After all the dental handpieces 5 to be disinfected are fixed, the sealing cover 15 can be picked up to drive the fixed dental handpieces 5, so that all the dental handpieces 5 enter the inner cavity of the disinfection box 13. At the same time, the inner wall of the positioning frame 36 is inserted into the outer wall of the clamping block 19, the outer wall of the fixed disk 31 is inserted into the top of the inner cavity of the disinfection box 13, and the outer wall of the sealing cover 15 is inserted into the inner wall of the magnetic attraction ring 14. The magnetic attraction ring 14 magnetically fixes the sealing cover 15, thereby covering the sealing cover 15 on the top of the disinfection box 13 to seal the inner cavity of the disinfection box 13. Then the disinfection treatment can be started. By starting the motor 17, the rotating shaft 18 is driven to rotate, so that the rotating shaft 18 drives the clamping block 19 to rotate. The clamping block 19 drives the turntable 35 to rotate synchronously. The turntable 35 drives the guide wheel 37 to slide on the inner wall of the fixed disk 31 synchronously. The guide wheel 37 guides the turntable 35, making the rotation of the turntable 35 more stable. The turntable 35 drives the first rotating rod 34 to rotate. The first rotating rod 34 drives the gear 33 to rotate, so that the outer wall of the gear 33 meshes with the teeth on the inner wall of the fixed disk 31, thereby making the gear 33 rotate self - rotatably. The gear 33 drives the first rotating rod 34 to rotate self - rotatably synchronously. At the same time, the first rotating rod 34 drives the fixing frame 41 to rotate. The fixing frame 41 drives the dental handpiece 5 to rotate, so that the dental handpiece 5 rotates around the center of the rotating shaft 18 while rotating self - rotatably, enabling the dental handpiece 5 to better contact the disinfectant and accelerating the disinfection efficiency, achieving the effect of accelerating the disinfection efficiency. After disinfection, open the valve on the outer wall of the liquid outlet pipe 16, so that the disinfectant in the inner cavity of the disinfection box 13 is discharged into the collection tank 12 through the liquid outlet pipe 16, thereby centrally collecting the used waste liquid for convenient subsequent treatment, achieving the effect of centralized collection. Then the dental handpiece 5 can be dried. Open the solenoid valve 25, and then start the blower 21. The blower 21 conveys cold air or hot air through the connecting pipe 22. The conveyed air enters the annular pipe 23, and then the annular pipe 23 conveys the air into the air outlet pipes 24 respectively. The air outlet pipes 24 blow out the air to dry the dental handpiece 5, achieving the effect of drying. Thus, the use experience is greatly improved.
