Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an integrated dental handpiece cleaning and lubrication machine. Background Technology

[0002] Dental handpieces are a common tool in dental treatment, mainly used for cleaning teeth and grinding decayed teeth. Because dental handpieces come into direct contact with the inside of the patient's mouth, they need to be cleaned and disinfected after use, and then lubricated.

[0003] In current technology, dental handpieces are typically cleaned by first placing them in a mechanical cleaning device, then drying their interior with a pressure air gun, and finally connecting the handpiece to a matching lubrication adapter or connector and inserting it into an automatic lubrication and maintenance machine for lubrication.

[0004] This method of processing requires a lot of machinery and tools, making it impossible to complete cleaning and oiling in one go, and the operation is cumbersome. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies that separate cleaning and lubrication of dental handpieces, which is cumbersome, this invention provides an integrated dental handpiece cleaning and lubrication machine.

[0006] The technical solution is as follows: A dental handpiece integrated cleaning and lubrication machine includes a connector, a support frame, a connecting head, a diverter tube, and a sliding tube. The connecting head is symmetrically fixed to the support frame, and a connector is located on the right side of the support frame. The connecting head has symmetrically arranged lubrication holes and through holes. The connector is used to connect to the tail end of the dental handpiece to facilitate cleaning and lubrication of the handpiece's interior. By holding the support frame and moving the connecting head to the right, it can engage with the adjacent lubrication holes and through holes, allowing water to be injected into them. A sliding tube is engaged inside each connecting head. The contact surface between the inner wall of the connecting head and the sliding tube is beveled to facilitate disengagement of the sliding tube from the connecting head. The outer side of the connecting head is also beveled to allow the sliding tube to engage with the connecting head. A diverter tube slidably connects the two sliding tubes. Water injected into the diverter tube can then enter through the sliding tube and the connecting head. The dental handpiece is cleaned and cleaned by a notched turntable, a return spring, an oil injection tube, a sliding mechanism, and a rotating mechanism. The notched turntable is rotatably mounted on a support frame. A diverter tube is fixedly connected to the notched turntable. An oil injection tube is slidably mounted below the notched turntable. The oil injection tube can be engaged with a rear connector by rotation, facilitating oil injection into the dental handpiece through the rear connector. Return springs connect both sliding tubes and the oil injection tube to the notched turntable. A sliding mechanism is provided on the connector, which moves the support frame, allowing for the cleaning and oiling of multiple dental handpieces one by one, making the operation simpler and more orderly. The rotating mechanism on the notched turntable, after cleaning, rotates the oil injection tube to engage with the rear connector, facilitating oil injection into the dental handpiece, thus completing the cleaning and oiling process in one step.

[0007] Furthermore, the sliding mechanism includes an electric slide rail, a mover, a controller, and an electric push rod. The connector is snapped onto the electric slide rail, and three connectors can be evenly snapped onto the electric slide rail to facilitate cleaning and lubricating three dental handpieces in one go. The electric slide rail is symmetrically equipped with movers that slide vertically. Both movers are slidably connected to the support frame. The controller is installed on the top of the upper mover, and the electric push rod is installed at the bottom of the upper mover. The telescopic rod of the electric push rod is connected to the support frame. Both the electric slide rail and the electric push rod are electrically connected to the controller.

[0008] Furthermore, the rotating mechanism includes a connecting pipe, a one-way shaft, a push rod, a push frame, and a tension spring. A connecting pipe is connected to the diverter pipe, and the connecting pipe is rotatably connected to the notched turntable. A one-way shaft is installed on the right side of the connecting pipe, and a threaded groove is opened on the one-way shaft. A push rod is slidably installed inside the connecting pipe, and a push frame is connected to the push rod. The push frame is slidably connected to the support frame, and two tension springs are connected between the push frame and the support frame. The push frame is located outside the one-way shaft. When the push frame moves to the right, it can be threadedly connected to the threaded groove on the one-way shaft, so that the one-way shaft and the connecting pipe can rotate the diverter pipe and the sliding pipe, causing the sliding pipe to disengage from the connecting head.

[0009] Furthermore, it also includes a reset mechanism, which includes an arc-shaped rack, a connecting block, a locking shaft, a one-way gear, a torsion spring, and a locking block. An arc-shaped rack is fixed to the front side of the notch turntable, and a connecting block is fixed to the front side of the support frame. A locking shaft is rotatably mounted on the connecting block. A one-way gear is installed on the left side of the locking shaft. The one-way gear meshes with the arc-shaped rack. A torsion spring connects the one-way gear and the connecting block. The torsion spring is sleeved on the locking shaft. After the dental handpiece is filled with oil, the one-way gear and the torsion spring can drive the notch turntable, the sliding tube, and the oil filling tube to automatically reverse and reset. A locking block is fixed on the lower moving part. The locking shaft can move to the right and engage with the locking block to limit the locking shaft and prevent the one-way gear from rotating.

[0010] Furthermore, it also includes a warning rod and a compression spring. The warning rod is slidably installed inside the oil injection pipe, and a compression spring is connected between the warning rod and the inside of the oil injection pipe. The upper rear side of the support frame is cut with a bevel. The warning rod can engage with the bevel on the support frame as the notch turntable rotates, so as to prompt the operator to engage the oil injection pipe with the connecting head on the rear side.

[0011] Furthermore, it also includes an air injection tube and an air injection pump. The air injection tube is connected between the two connectors, and the air injection pump is installed on the air injection tube. Air is injected into the dental handpiece by the air injection pump to remove excess moisture inside, which facilitates the subsequent oil injection.

[0012] Furthermore, it also includes a photosensitive sensor and an indicator light. An indicator light is installed on the top right side of the upper mover, and a photosensitive sensor is installed on the left side of the support frame. Both the photosensitive sensor and the indicator light are electrically connected to the controller. The notch turntable rotates with the oil filling pipe, which blocks the beam of light emitted by the photosensitive sensor, causing the photosensitive sensor to control the indicator light to light up through the controller, so as to prompt the staff to carry out the oil filling work.

[0013] Furthermore, it also includes sealing rings. Both connecting heads have sealing rings on their right sides. After the connecting heads are engaged with the corresponding oil filling holes and through holes, the sealing between them can be guaranteed, preventing water leakage during the water filling process.

[0014] This invention provides an integrated dental handpiece cleaning and lubrication machine, which has the following advantages: 1. By connecting the two connectors to the oil filling hole and the through hole respectively, the inside of the dental handpiece can be rinsed. After rinsing, the rotating mechanism can rotate the oil filling tube to engage with the connector on the rear side, so as to facilitate the oil filling of the dental handpiece. In this way, cleaning and oil filling can be carried out in one step without the need for other machines to assist in the process. 2. Under the action of the sliding mechanism, multiple dental handpieces can be cleaned and lubricated in sequence, improving work efficiency and making the cleaning and lubrication work proceed in an orderly manner; 3. After cleaning and lubricating a dental handpiece, the reset mechanism can automatically reverse and reset the notch turntable, connecting head, sliding tube and lubrication tube, without manual operation, which is more labor-saving. 4. Under the action of the warning lever, after the oil filling tube is connected to the connecting head on the rear side, it will automatically spring to the right, thus no longer blocking the oil filling tube, so as to remind the staff to fill the dental handpiece with oil. 5. Injecting air into the dental handpiece using an air pump dries the interior, making it easier to apply lubricant later. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings. Example

[0029] A dental handpiece integrated cleaning and lubrication machine, such as Figures 1-3 As shown, the device includes a connector 1, a support frame 4, a connecting head 5, a notched turntable 6, a diverter tube 7, a sliding tube 8, a return spring 9, an oil injection tube 10, a sliding mechanism 11, and a rotating mechanism 12. The support frame 4 has a rotating notched turntable 6. The connecting heads 5 are symmetrically connected to the support frame 4. The connector 1 is located on the right side of the support frame 4. The connector 1 has symmetrically arranged oil injection holes 2 and through holes 3. The connector 1 is used to connect to the tail end of a dental handpiece to facilitate cleaning and oiling the inside of the dental handpiece. By holding the support frame 4 and moving the connecting head 5 to the right, it can engage with the nearby oil injection holes 2 and through holes 3, allowing water to be injected into the oil injection holes 2 and through holes 3 through the connecting head 5. Sliding tubes 8 are engaged inside each connecting head 5. A diverter tube 7 is slidably connected between the two sliding tubes 8. The diverter tube 7 is fixedly connected to the notched turntable 6. The inner wall of the connecting head 5 is connected to the sliding tube 8. The contact surface of the sliding tube 8 is beveled to facilitate the disengagement of the sliding tube 8 from the connecting head 5. The outer side of the connecting head 5 is also beveled to allow the sliding tube 8 to engage with it. A sliding oil injection tube 10 is provided at the lower part of the notched turntable 6. The oil injection tube 10 can engage with the rear connecting head 5 by rotation, allowing oil to be injected into the dental handpiece through the rear connecting head 5. Both sliding tubes 8 and the oil injection tube 10 are connected to the notched turntable 6 by a return spring 9. A sliding mechanism 11 is provided on the connecting head 1. The sliding mechanism 11 moves the support frame 4, enabling cleaning and oiling of multiple dental handpieces one by one, making the operation simpler and more orderly. A rotating mechanism 12 is provided on the notched turntable 6. After cleaning the dental handpiece, the rotating mechanism 12 rotates the oil injection tube 10 to engage with the rear connecting head 5, facilitating oiling of the dental handpiece and integrating cleaning and oiling into one process.

[0030] like Figure 1 and Figure 4 As shown, the sliding mechanism 11 includes an electric slide rail 111, a mover 112, a controller 113, and an electric push rod 114. The connector 1 is snapped onto the electric slide rail 111, and three connectors 1 can be evenly snapped onto the electric slide rail 111 to facilitate cleaning and lubricating three dental handpieces in one go. The electric slide rail 111 is symmetrically equipped with movers 112, and both movers 112 are slidably connected to the support frame 4. The controller 113 is installed on the top of the upper mover 112, and the electric push rod 114 is installed on the bottom of the upper mover 112. The telescopic rod of the electric push rod 114 is connected to the support frame 4. The electric slide rail 111 and the electric push rod 114 are both electrically connected to the controller 113.

[0031] like Figure 5 , Figure 6 and Figure 7 As shown, the rotating mechanism 12 includes a connecting pipe 121, a one-way shaft 122, a push rod 123, a push frame 124, and a tension spring 125. The connecting pipe 121 is connected to the diverter pipe 7 and is rotatably connected to the notched turntable 6. The one-way shaft 122 is installed on the right side of the connecting pipe 121 and has a threaded groove. The push rod 123 is slidably provided inside the connecting pipe 121 and the push frame 124 is connected to the push rod 123. The push frame 124 is slidably connected to the support frame 4 and two tension springs 125 are connected between the push frame 124 and the support frame 4. The push frame 124 is located outside the one-way shaft 122. The push frame 124 can move to the right and be threadedly connected to the threaded groove on the one-way shaft 122, so that the one-way shaft 122 and the connecting pipe 121 can rotate the diverter pipe 7 and the sliding pipe 8, causing the sliding pipe 8 to disengage from the connecting head 5.

[0032] When cleaning and lubricating a dental handpiece, first thread connector 1 onto the end of the dental handpiece, then snap connector 1 onto the electric slide rail 111. Three connectors 1 can be snapped onto one electric slide rail 111 for easy cleaning of the three dental handpieces. The controller 113 controls the retraction of the electric push rod 114, causing the electric push rod 114, along with the support frame 4, connecting head 5, notched turntable 6, diverter tube 7, sliding tube 8, and lubrication tube 10, to move to the right. The rotating mechanism 12 will also move accordingly. After the connecting head 5 is snapped into the lubrication hole 2 and through hole 3, the electric push rod 114 can be closed. Then, connect an external water pipe to the diverter tube 7 and inject water into it. The water will flow through the diverter tube 7 and sliding tube 8 to the connecting head. Water flows into the dental handpiece through the connector 5 and then into the connector 1 and the dental handpiece, rinsing the inside of the dental handpiece. Simultaneously, water in the diverter pipe 7 flows into the connecting pipe 121, pushing the push rod 123 and the push bracket 124 to the right, stretching the tension spring 125. The push bracket 124 then connects with the threaded groove on the one-way shaft 122, causing the one-way shaft 122 to rotate freely. Excess water inside the dental handpiece is discharged through the other end. After cleaning the inside of the dental handpiece, water injection stops, and no more water pushes the push rod 123. The push bracket 124, under the reset action of the tension spring 125, moves the push rod 123 to the left. The push bracket 124 then drives the one-way shaft 122 and the connecting pipe 121 to rotate, causing the diverter pipe 121 to rotate freely. When the flow pipe 7, notch turntable 6, sliding pipe 8, and oil injection pipe 10 rotate, the sliding pipe 8 will be squeezed to the left due to the inclined inner wall of the connecting head 5. The corresponding return spring 9 will also be compressed, causing the sliding pipe 8 to disengage from the connecting head 5. After the sliding pipe 8 disengages from the connecting head 5, it will rebound to the right due to the return spring 9. When the oil injection pipe 10 contacts the inclined outer wall of the rear connecting head 5, it will be squeezed to the left, compressing the corresponding return spring 9. After the oil injection pipe 10 aligns with the rear connecting head 5, it will rebound and lock into the rear connecting head 5 due to the return spring 9. After the oil injection pipe 10 locks into the rear connecting head 5, the push frame 124 will also disengage from the one-way shaft 122. The turntable 6 stops rotating, and oil can then be injected into the oil filling tube 10. The oil enters the oil filling hole 2 through the connecting head 5 on the rear side, and then enters the dental handpiece through the connector 1 to lubricate and maintain the internal structure of the dental handpiece. After the oil filling is completed, the electric push rod 114 is extended, causing it to move to the left and reset along with the support frame 4, connecting head 5, notched turntable 6, diverter tube 7, sliding tube 8, and oil filling tube 10. The rotating mechanism 12 will also move to the left and reset, so that the connecting head 5 is no longer stuck with the oil filling hole 2 and the through hole 3. This completes the cleaning and oiling of the dental handpiece. The notched turntable 6 can be manually reversed and reset, causing it to move to the left and reset along with the diverter tube 7, oil filling tube 10, and sliding tube 8, so that the oil filling tube 10 is disengaged from the connecting head 5 on the rear side.The two sliding tubes 8 are respectively engaged with the corresponding connecting heads 5. The controller 113 controls the electric slide rail 111, causing it to move forward with the mover 112, which in turn moves the support frame 4 and the electric push rod 114 forward. The components on the support frame 4 will move accordingly, aligning the connecting head 5 with the oil filling hole 2 and through hole 3 on the next connecting head 1. The electric slide rail 111 can then be closed. This process can be repeated to clean and lubricate the second dental handpiece. When using the electric slide rail 111, it can be programmed via computer to ensure that the distance the mover 112 moves is consistent each time, thus determining the distance the support frame 4 moves. This facilitates the cleaning and lubrication of each dental handpiece on the electric slide rail 111. After cleaning and lubrication, the connecting head 1 is removed from the electric slide rail 111, and the dental handpiece is disconnected from the connecting head 1. The dental handpiece is then ready for normal use. Example

[0033] Based on Example 1, such as Figure 1 and Figure 8 As shown, it also includes a reset mechanism 13, which includes an arc-shaped rack 131, a connecting block 132, a retaining shaft 133, a one-way gear 134, a torsion spring 135, and a retaining block 136. The arc-shaped rack 131 is welded to the front side of the notched turntable 6, and the connecting block 132 is fixed to the front side of the support frame 4. The retaining shaft 133 is rotatably mounted on the connecting block 132. The one-way gear 134 is mounted on the left side of the retaining shaft 133. The one-way gear 134 meshes with the arc-shaped rack 131. A torsion spring 135 is connected between the one-way gear 134 and the connecting block 132. The torsion spring 135 is sleeved on the retaining shaft 133. The retaining block 136 is connected to the lower moving part 112. The retaining shaft 133 can move to the right to engage with the retaining block 136 to restrict the retaining shaft 133 and prevent the one-way gear 134 from rotating.

[0034] During cleaning inside the dental handpiece, the support frame 4 moves to the right, causing the two connecting heads 5 to engage with the oil filling hole 2 and the through hole 3 respectively. The notched turntable 6 moves to the right along with the arc-shaped rack 131. At the same time, the support frame 4 moves to the right along with the connecting block 132, the retaining shaft 133, and the one-way gear 134, causing the retaining shaft 133 to engage with the retaining block 136, thus preventing the torsion spring 135 from resetting. After cleaning inside the dental handpiece is completed, the rotating mechanism 12 causes the notched turntable 6 to rotate along with the diverter tube 7, the sliding tube 8, and the oil filling tube 10, causing the two sliding tubes 8 to disengage from the connecting heads 5, while the oil filling tube 10 engages with the connecting head 5 on the rear side. When the notched turntable 6 rotates, it also drives the arc-shaped rack 131 to rotate. The arc-shaped rack 131 drives the one-way gear 134 to rotate freely, and the torsion spring 135 will deform, allowing the dental handpiece to be filled with oil. After the oil filling is completed, the electric push rod 114 moves the support frame 4 to the left to reset, and then moves all the components on the support frame 4, so that the locking shaft 133 is no longer locked with the locking block 136. The one-way gear 134 will then reverse and reset under the reset action of the torsion spring 135, thereby driving the locking shaft 133 to reverse. The one-way gear 134 simultaneously drives the arc-shaped rack 131 and the notched turntable 6 to reverse, so that the notched turntable 6, along with the sliding tube 8 and the oil filling tube 10, reverses and resets. The sliding tube 8 then locks with the connecting head 5, while the oil filling tube 10 disengages from the connecting head 5 on the rear side.

[0035] like Figure 9 , Figure 10 and Figure 11 As shown, it also includes a warning rod 141 and a compression spring 142. The oil injection pipe 10 is slidably provided with a warning rod 141 for alerting the staff. The warning rod 141 is connected to the inside of the oil injection pipe 10 by a compression spring 142. The upper rear side of the support frame 4 is cut with a bevel. The warning rod 141 can engage with the bevel on the support frame 4 as the notch turntable 6 rotates.

[0036] As the oil filling tube 10 rotates with the notch turntable 6, it simultaneously rotates the warning rod 141. When the oil filling tube 10 contacts the rear connecting head 5, it is squeezed and moved to the left. Since the compression spring 142 is initially in a stretched state, the oil filling tube 10 moves to the left, and the compression spring 142 will return to its original position and shorten. The warning rod 141 will then contact the inclined surface on the support frame 4. As the oil filling tube 10 aligns and engages with the rear connecting head 5, the warning rod 141 will also move to the right and engage with the inclined surface due to the reset spring 9, thus no longer blocking the oil filling tube 10. Oil can then be injected into the dental handpiece, achieving the warning effect and alerting the staff to avoid oil overflow caused by directly injecting oil before the oil filling tube 10 is fully engaged with the rear connecting head 5. After oil injection is completed, the reset mechanism 13 will cause the notch turntable 6 to reverse and reset with the oil filling tube 10, which in turn will cause the warning rod 141 to reverse, causing the warning rod 141 to disengage from the inclined surface and be squeezed and moved to the left, stretching the reset spring 9.

[0037] like Figure 12 As shown, it also includes an air injection tube 151 and an air injection pump 152. The air injection tube 151 is connected between the two connectors 5, and the air injection tube 151 is equipped with an air injection pump 152 for injecting air into the dental handpiece.

[0038] After cleaning the inside of the dental handpiece, it is necessary to drain the water inside the dental handpiece. The air pump 152 can be turned on to inject air into the air tube 151. The air will enter the inside of the dental handpiece through the connector 5, thereby cleaning the excess water inside the dental handpiece and drying the inside of the connector 5. After cleaning, the air pump 152 can be turned off.

[0039] like Figure 3 and Figure 4 As shown, it also includes a photosensitive sensor 161 and an indicator light 162. An indicator light 162 for lighting up to alert workers is installed on the top right side of the upper mover 112. A photosensitive sensor 161 for sensing changes in brightness is installed on the left side of the support frame 4. Both the photosensitive sensor 161 and the indicator light 162 are electrically connected to the controller 113.

[0040] Initially, the light beam shone directly from the photosensitive sensor 161 passes through the notch on the notched turntable 6. As the notched turntable 6 rotates with the two connecting heads 5 and the oil filling tube 10, it blocks the light beam. The photosensitive sensor 161 senses the change in brightness and sends a signal to the controller 113. The controller 113 then controls the indicator light 162 to illuminate, prompting the staff to start oiling the dental handpiece, thus ensuring the cleaning and oiling process proceeds smoothly. After the oiling is completed, the notched turntable 6, with the two connecting heads 5 and the oil filling tube 10, reverses and resets, and the notched turntable 6 no longer blocks the light beam. The controller 113 then controls the indicator light 162 to turn off.

[0041] like Figure 1 As shown, it also includes a sealing ring 17. Both connecting heads 5 are fitted with sealing rings 17 on their right sides. After the connecting head 5 is engaged with the corresponding oil injection hole 2 and through hole 3, it can ensure the sealing between the two and prevent water leakage during the water injection process.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
