Description

Technical Field

[0001] The present invention relates to the technical field of oral mirrors, and in particular to an oral mirror used in stomatology. Background Art

[0002] A dental mirror is a commonly used inspection tool in the dental field, mainly used to help dentists or dental hygienists better observe the inside of a patient's mouth. This mirror usually has a reflective function, which can help dentists see angles that are difficult to observe directly, such as the back of the teeth or deep in the mouth.

[0003] The existing dental mirror mainly consists of a mirror and a handle, and its function is relatively simple. Therefore, it is found during use that the liquid in the mouth and the debris produced by grinding teeth can easily contaminate the mirror, causing the field of view on the mirror to become blurred, which will affect the medical staff's observation and treatment of the oral cavity and indirectly increase the risk during the treatment process. Summary of the invention

[0006] In order to make the circular mirror rotate continuously, preferably, the driving part includes a driving motor fixedly installed on the bottom of the circular groove, and a horizontal axis and a vertical axis are rotatably connected in the circular groove, wherein the lower end of the circular mirror is connected to the upper end of the vertical axis, the horizontal axis and the vertical axis are connected by two meshing first gears, and the output shaft of the driving motor is connected to the horizontal axis by two mutually meshing second gears.

[0007] In order to make the circular mirror shake back and forth, further, a circular ring is rotatably connected to the bottom of the circular mirror, a spring is installed between the circular ring and the inner bottom of the circular groove, and a reciprocating part for indirectly lifting the circular ring is provided in the circular groove.

[0008] In order to make the circular mirror shake back and forth, the reciprocating part further includes a cam fixedly mounted on the outer wall of the horizontal axis, and the outer wall of the cam is fitted to the lower end of the circular ring, wherein the lower end of the circular mirror is fixedly connected with a sleeve, and the vertical axis is fixedly connected with a sliding column inserted in the sleeve.

[0009] In order to facilitate the use of the entire device, preferably, the input end of the nozzle is rotatably connected to a rotating tube, the inner wall of the rotating tube is fixedly mounted with fan blades, the rotating tube is connected to the horizontal axis through a chain drive, and the end of the rotating tube is rotatably connected to a connecting tube extending into the liquid storage cavity of the handle.

[0010] In order to facilitate the recovery of the cleaning liquid generated during cleaning, further, a recovery cover is fixedly connected to the edge of the disc, the opening of the recovery cover faces the output end of the nozzle, and the recovery cover and the nozzle are symmetrically arranged on both sides of the disc, wherein an end cover is installed at the upper end of the handle, and a recovery pipe extending into the end cover is fixedly connected to the recovery cover, and a filter element is installed in the end cover.

[0011] In order to facilitate drying the cleaned round mirror, preferably, a nozzle close to the nozzle is fixedly mounted on the disc, and the end of the nozzle faces the surface of the round mirror and the recovery cover, and an air storage bag is fixedly mounted in the circular groove, the air storage bag is connected to the nozzle through a connecting pipe, and a valve is installed on the nozzle.

[0012] In order to facilitate the inflation of the air storage airbag, preferably, an elastic airbag is fixedly installed in the circular groove and pressed against the lower end surface of the circular mirror, and an intake pipe and an exhaust pipe connected thereto are fixedly connected to the elastic airbag, wherein a one-way valve is fixedly installed in both the intake pipe and the exhaust pipe, and the end of the exhaust pipe extends into the air storage airbag.

[0013] In order to facilitate brushing the round mirror, the upper end of the disc is further fixedly connected to a support, a rotating rod is rotatably mounted on the support, an arc rod is fixedly connected to the rotating rod and is attached to the inner wall of the circular groove, a brush is provided at the lower end of the arc rod facing the upper end surface of the round mirror, and a swinging part is provided on the round mirror to drive the rotating rod to rotate.

[0015] Compared with the prior art, the present invention provides a dental mirror for oral medicine, which has the following beneficial effects: 1. The oral mirror used in stomatology drives the internal fan blades to rotate through the rotating tube. The rotating tube absorbs the cleaning liquid in the handle through the internal fan blades and sprays it to the surface of the round mirror through the nozzle, thereby automatically completing the flushing of the round mirror. The rotating round mirror can be fully flushed, which makes it more convenient for medical staff to use the round mirror, reduces the impact on treatment, and indirectly reduces the risk during treatment.

[0016] 2. The oral mirror used in stomatology drives the cam to rotate through the horizontal axis, and the cam will intermittently press the round mirror. The continuously rotating cam will make the round mirror vibrate back and forth in the circular groove, thereby improving the flushing effect of the round mirror. When the round mirror vibrates back and forth, the round mirror will drive the sleeve to slide back and forth on the sliding column.

[0017] 3. The oral mirror used in stomatology absorbs the cleaning liquid in the recovery cover through the recovery tube. The cleaning liquid is filtered by the filter element and flows back to the liquid storage cavity of the handle, thereby completing the recovery of the cleaning liquid. In this way, the handle can be used continuously without an external liquid inlet tube. The overall structure will be more compact and flexible, which is convenient for medical staff to operate and use.

[0018] 4. The oral mirror used in stomatology can quickly dry the round mirror by opening the valve in the nozzle, so as to reduce the influence of water stains on the clarity of the round mirror, thereby facilitating the operation of medical staff and significantly reducing safety hazards. The reciprocating shaking round mirror can also quickly dry the water stains on its surface.

[0019] 5. The oral mirror used in stomatology drives the annular boss to approach the surface of the rotating rod through the round mirror. The rotating round mirror drives the rotating rod to rotate through the annular boss, and the rotating rod drives the arc rod to rotate. The arc rod drives the brush to sweep on the surface of the round mirror, thereby improving the cleaning effect of the round mirror.

[0020] 6. The oral mirror used in stomatology drives the rotating rod to reverse through the torsion spring, and the arc rod drives the brush to reset again and fit on the inner wall of the circular groove, so that the arc rod can avoid blocking the round mirror and ensure the use of the round mirror.

The rotating tube 11 is connected to the horizontal axis 7 via a chain drive 12, and the end of the rotating tube 11 is rotatably connected to a connecting tube 13 extending into the liquid storage cavity of the handle 1.

[0039] Specifically, when the vertical shaft 6 rotates, the vertical shaft 6 will also drive the rotating tube 11 to rotate through the chain drive 12, and the rotating tube 11 will drive the internal fan blades to rotate. The rotating tube 11 will absorb the cleaning liquid in the handle 1 through the internal fan blades, and spray it to the surface of the round mirror 4 through the nozzle 5, thereby automatically completing the flushing of the round mirror 4.

[0041] Specifically, during the flushing process, most of the sprayed cleaning liquid will flow into the recovery cover 14, and negative pressure will be generated in the liquid storage chamber of the handle 1, and the cleaning liquid in the recovery cover 14 will be absorbed through the recovery pipe 15. The cleaning liquid is filtered by the filter element 17 and flows back into the liquid storage chamber of the handle 1, thus completing the recovery of the cleaning liquid. In this way, the handle 1 does not need to be connected to an external liquid inlet pipe and can be used continuously. The overall structure will be more compact and flexible, which is convenient for medical staff to operate and use.

[0042] Example 3: Reference Figure 3 as well as Figure 5-Figure 7 , which is basically the same as the second embodiment, and further, a specific implementation scheme for shaking the circular mirror 4 is specifically added.

[0043] The bottom of the circular mirror 4 is rotatably connected to a circular ring 21, a spring 22 is installed between the circular ring 21 and the inner bottom of the circular groove 3, and a reciprocating portion for indirectly lifting the circular ring 21 is provided in the circular groove 3; the reciprocating portion includes a cam 20 fixedly installed on the outer wall of the horizontal axis 7, and the outer wall of the cam 20 is fitted to the lower end of the circular ring 21, wherein the lower end of the circular mirror 4 is fixedly connected to a sleeve 18, and the vertical axis 6 is fixedly connected to a sliding column 19 inserted in the sleeve 18.

[0044] Specifically, when in use, start the driving motor 9, the driving motor 9 will drive the horizontal axis 7 to rotate through two mutually meshing second gears 10, and the horizontal axis 7 will drive the vertical axis 6 to rotate through two mutually meshing first gears 8, and the vertical axis 6 will drive the round mirror 4 to rotate, so that the round mirror 4 can be fully rinsed, and when the horizontal axis 7 rotates, the horizontal axis 7 will also drive the cam 20 to rotate, and the cam 20 will intermittently press the round mirror 4. When the round mirror 4 is pressed, it will slide toward the upper port direction of the circular groove 3. When the round mirror 4 is not pressed, the spring 22 will pull the round mirror 4 to reset through the circular ring 21, so that the continuously rotating cam 20 will cause the round mirror 4 to shake back and forth in the circular groove 3, thereby improving the flushing effect of the round mirror 4, and when the round mirror 4 shakes back and forth, the round mirror 4 will drive the sleeve 18 to slide back and forth on the sliding column 19.

[0045] Example 4: Reference Figure 1 as well as Figure 4-Figure 6 , which is basically the same as the third embodiment, and further, a specific implementation scheme for drying the circular mirror 4 is specifically added.

[0046] A nozzle 24 is fixedly mounted on the disc 2 and is in close contact with the nozzle 5, and the end of the nozzle 24 faces the surface of the circular mirror 4 and the inside of the recovery cover 14. An air storage bag 23 is fixedly mounted in the circular groove 3. The air storage bag 23 is connected to the nozzle 24 through a connecting pipe 25, and a valve is installed on the nozzle 24.

[0047] Specifically, during use, when the round mirror 4 is contaminated, the cleaning liquid can be sprayed onto the surface of the round mirror 4 through the nozzle 5, thereby automatically completing the flushing of the round mirror 4, and the driving part can drive the round mirror 4 to rotate, and the rotating round mirror 4 can be fully flushed, so that medical staff can use the round mirror 4 more conveniently, reduce the impact on treatment, and indirectly reduce the risk during treatment. After cleaning, open the valve in the nozzle 24, so that the compressed air in the air storage bag 23 will be delivered to the nozzle 24 through the connecting pipe 25, and the nozzle 24 will blow the air toward the rotating round mirror 4, so as to complete the rapid drying of the round mirror 4, so as to reduce the impact of water stains on the clarity of the round mirror 4, thereby facilitating the operation of medical staff, significantly reducing safety hazards, and the reciprocating shaking round mirror 4 will also quickly dry the water stains on its surface.

[0048] An elastic airbag 26 is fixedly installed in the circular groove 3 and pressed against the lower end surface of the circular mirror 4. An air intake pipe 28 and an exhaust pipe 27 which are connected to the elastic airbag 26 are fixedly connected. A one-way valve is fixedly installed in the air intake pipe 28 and the exhaust pipe 27, and the end of the exhaust pipe 27 extends into the air storage bag 23.

[0049] Specifically, when the round mirror 4 moves up and down, the round mirror 4 will indirectly squeeze the elastic airbag 26. When the elastic airbag 26 is squeezed, the air storage airbag 23 will be inflated through the exhaust pipe 27, so that there is no need to manually inflate the air storage airbag 23, which is more convenient to use. When the elastic airbag 26 is not squeezed, the elastic airbag 26 will elastically reset and inhale the outside air through the intake pipe 28.

[0050] Example 5: Reference Figure 4 as well as Fig. 9 , which is basically the same as the fourth embodiment, and further, a specific implementation scheme for improving the flushing effect of the circular mirror 4 is specifically added.

[0051] The upper end of the above-mentioned disc 2 is fixedly connected to a support 29, and a rotating rod 30 is rotatably installed on the support 29. An arc rod 32 that is in contact with the inner wall of the circular groove 3 is fixedly connected to the rotating rod 30. The lower end of the arc rod 32 is provided with a brush 33 facing the upper end surface of the circular mirror 4. The circular mirror 4 is provided with a swinging part that drives the rotating rod 30 to rotate; the swinging part includes an annular boss 31 fixedly connected to the upper end edge of the circular mirror 4, and a torsion spring is installed between the rotating rod 30 and the support 29. When the circular mirror 4 moves upward, the inner wall of the annular boss 31 will fit with the outer wall of the rotating rod 30.

[0052] Specifically, when the horizontal shaft 7 rotates, the horizontal shaft 7 will also drive the cam 20 to rotate, and the cam 20 will intermittently press the round mirror 4. When the round mirror 4 is pressed, it will slide toward the upper end of the circular groove 3. When the round mirror 4 is not pressed, the spring 22 will pull the round mirror 4 to reset through the circular ring 21. Then, the continuously rotating cam 20 will cause the round mirror 4 to shake back and forth in the circular groove 3, thereby improving the flushing effect of the round mirror 4. When the round mirror 4 shakes back and forth, the round mirror 4 will drive the sleeve 18 to slide back and forth on the sliding column 19. When the round mirror 4 moves toward the opening direction of the circular groove 3, the round mirror 4 will drive the annular boss 31 to approach the rotating rod 30. The rotating round mirror 4 will drive the rotating rod 30 to rotate through the annular boss 31, and the rotating rod 30 will drive the arc rod 32 to rotate, and the arc rod 32 will drive the brush 33 to sweep on the surface of the round mirror 4, thereby improving the cleaning effect of the round mirror 4. When the round mirror 4 slides in the opposite direction to reset, the annular boss 31 will move away from the rotating rod 30. At this time, the torsion spring will drive the rotating rod 30 to reverse, and the arc rod 32 will drive the brush 33 to reset again and fit against the inner wall of the circular groove 3. When the horizontal axis 7 stops rotating, the torsion spring will also drive the arc rod 32 to reset, so as to avoid the arc rod 32 from blocking the round mirror 4 and ensure the use of the round mirror 4.

[0053] The oral mirror used in stomatology, when in use, when the round mirror 4 is contaminated, the valve in the nozzle 5 and the driving motor 9 are opened, the driving motor 9 will drive the horizontal axis 7 to rotate through two mutually meshing second gears 10, the horizontal axis 7 will drive the vertical axis 6 to rotate through two mutually meshing first gears 8, the vertical axis 6 will drive the round mirror 4 to rotate, and the vertical axis 6 will also drive the rotating tube 11 to rotate through the chain drive 12, the rotating tube 11 will drive the internal fan blades to rotate, the rotating tube 11 will absorb the cleaning liquid in the handle 1 through the internal fan blades, and spray it to the surface of the round mirror 4 through the nozzle 5, thereby automatically completing the flushing work of the round mirror 4, and the rotating round mirror 4 can be fully flushed, so that medical staff can use the round mirror 4 more conveniently and reduce the impact on treatment.

[0054] When the horizontal shaft 7 rotates, the horizontal shaft 7 will also drive the cam 20 to rotate, and the cam 20 will intermittently press the round mirror 4. When the round mirror 4 is pressed, it will slide toward the upper end of the circular groove 3. When the round mirror 4 is not pressed, the spring 22 will pull the round mirror 4 to reset through the circular ring 21. Then the continuously rotating cam 20 will cause the round mirror 4 to shake back and forth in the circular groove 3, thereby improving the flushing effect of the round mirror 4. When the round mirror 4 shakes back and forth, the round mirror 4 will drive the sleeve 18 to slide back and forth on the sliding column 19.

[0055] During the flushing process, most of the sprayed cleaning liquid will flow into the recovery cover 14, and negative pressure will be generated in the liquid storage chamber of the handle 1, and the cleaning liquid in the recovery cover 14 will be absorbed through the recovery pipe 15. The cleaning liquid will be filtered by the filter element 17 and flow back into the liquid storage chamber of the handle 1, thus completing the recovery of the cleaning liquid. In this way, the handle 1 does not need to be connected to an external liquid inlet pipe and can be used continuously. The overall structure will be more compact and flexible, which is convenient for medical staff to operate and use.

[0056] After cleaning, the valve in the nozzle 24 is opened, and the compressed air in the air storage bag 23 will be delivered to the nozzle 24 through the connecting pipe 25, and the nozzle 24 will blow the air toward the rotating round mirror 4, so as to complete the quick drying of the round mirror 4, so as to reduce the influence of water stains on the clarity of the round mirror 4, thereby facilitating the operation of medical staff and significantly reducing safety hazards. The reciprocating shaking of the round mirror 4 will also quickly dry the water stains on its surface.

[0057] When the round mirror 4 moves up and down, the round mirror 4 will indirectly squeeze the elastic airbag 26. When the elastic airbag 26 is squeezed, the air storage airbag 23 will be inflated through the exhaust pipe 27, so there is no need to manually inflate the air storage airbag 23, which is more convenient to use. When the elastic airbag 26 is not squeezed, the elastic airbag 26 will elastically reset and inhale the outside air through the intake pipe 28.

[0058] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
