Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a cleaning quality test monitoring device special for a dental handpiece comprises a cleaning machine 1. The middle part of the cleaning machine 1 is provided with a water storage tank 2. The water storage tanks 2 are used for storing cleaning water (liquid) after cleaning the dental handpiece respectively. The two sides of the water storage tank 2 are provided with a plurality of mounting frames 3 in a sliding manner. A plurality of communicating pipes 4 are connected between the plurality of mounting brackets 3. The mounting racks 3 may be connected to a water pump by means of hoses for delivering the washing liquid to one of the mounting racks 3 and to the respective mounting rack 3 via the communication pipes 4. Each mounting rack 3 is provided with a water outlet pipe 5 (the water outlet pipe 5 is also made of rubber with softer material). The cleaning liquid fully cleans the dental handpiece arranged above the water outlet pipe 5 through the water outlet pipe 5.
And a conveying frame 6 is arranged above the water outlet pipe 5. The conveying frame 6 is provided with a mounting hole 7 corresponding to the water outlet pipe 5 and positioned on the same vertical surface with the water outlet pipe 5. The mounting hole 7 is used for mounting the disassembled dental handpiece, so that the bottom of the dental handpiece penetrates into the mounting hole 7, and the dental handpiece is cleaned through the water outlet pipe 5.
The central positions of the mounting frames 3 are fixedly provided with lifting plates 8. The lifting plate 8 is connected with a chain 9 for driving the lifting plate 8 to move up and down. The chain 9 is provided with a sprocket 10. One end of the chain 9 is fixedly connected with the chain wheel 10. When the chain wheel 10 rotates, the chain 9 can be retracted, so that the chain 9 can drive the lifting plate 8 to move up and down. When the lifting plate 8 moves upwards, the water outlet pipe 5 is communicated with the mounting hole 7 in a matching mode, so that cleaning liquid flows out through the water outlet pipe 5, and then enters the dental handpiece through the mounting hole 7 to clean the dental handpiece.
Wherein the respective carriages 6 are connected together with a fixing plate 11. The fixing plate 11 is used to connect the respective carriers 6 to each other. In the present application, 16 transfer frames 6 are exemplified by being divided into four rows and four columns. Two rows of the conveying frames 6 are used for placing the transparent dental handpiece model, and the other two rows of the conveying frames 6 are used for placing the dental handpiece to be cleaned. In cleaning, the cleaning degree of the dental handpiece to be cleaned is determined by injecting artificial blood into the transparent dental handpiece model and then observing the cleaning condition of the transparent dental handpiece model by naked eyes.
As shown in fig. 5, 6, 7, and 8, a drive case 12 is provided on the fixed plate 11 side. A drive assembly 13 is disposed within the drive housing 12. The driving assembly 13 includes a first sliding rod 14 fixedly connected to the fixed plate 11. The first sliding rod 14 is meshed with a first gear 15, the first gear 15 is meshed with a second gear 16, and the second gear 16 is meshed with a third gear 17. The third gear 17 is meshed with a second sliding rod 18. The second gear 16 is connected with a driving motor 19. When the second gear 16 rotates, the first gear 15 and the third gear 17 are rotated, so that the third gear 17 and the first gear 15 rotate in the same direction. The first sliding rod 14 and the second sliding rod 18 which are respectively meshed with the first gear 15 and the third gear 17 move simultaneously in the same direction.
Preferably, the tooth spacing on the first sliding rod 14 is twice the tooth spacing of the blocks on the third sliding rod 27. When the slide bar I14 moves by the gear I15, the distance is half of the distance moved by the slide bar III 27.
The second sliding rod 18 penetrates through the fixed plate 11 and is fixedly connected with a sliding plate 20. As shown in fig. 3 and 4, a plurality of reagents or test strips 21 for detecting whether or not blood components are contained in the wash solution, such as a blood detector or a luminol-containing test strip 21, are provided on one side of the slide plate 20. Correspondingly, a collecting groove 22 is correspondingly arranged on one side of each conveying frame 6. The collecting tank 22 is communicated with an expansion pipe 23. The bottom of the pressure expansion pipe 23 is provided with a liquid outlet slit 24. The sliding plate 20 is fixedly provided with a squeezing plate 25 corresponding to one side of the pressure expansion pipe 23. When the pressure expansion pipe 23 is pressed by the outside of the pressing plate 25, the liquid outlet gap 24 is opened, and when the pressure expansion pipe is not pressed by the outside of the pressing plate 25, the liquid outlet gap 24 is closed.
In addition, when the water outlet pipe 5 injects cleaning liquid into the mounting hole 7, the cleaning liquid is collected in the collecting groove 22, meanwhile, the collecting groove 22 is communicated with the mounting hole 7 again, when the water outlet pipe 5 is communicated with the mounting hole 7, the communication position of the collecting groove 22 and the mounting hole 7 is sealed, and when the water outlet pipe 5 is used for cleaning the dental handpiece, the cleaning liquid overflows the collecting groove 22 and flows into the water storage tank 2 along the conveying frame 6.
As shown in fig. 5, 6, 7 and 8, a connecting plate 26 is fixedly connected to one side of the second sliding rod 18. The other side of the connecting plate 26 is fixedly connected with a third sliding rod 27 with the same structure as the second sliding rod 18. The third slide bar 27 is engaged with a driving wheel 28. A fixed block 29 is fixedly arranged at the peripheral edge position of the driving wheel 28. The fixed block 29 is matched with a swing rod 30. The swing link 30 is provided with a sliding groove 31 for the fixed block 29 to slide. One side of the swing rod 30 is engaged with a driving rod 32. The driving rod 32 is designed as a double-sided toothed block, and the bottom of the driving rod 32 is engaged with a connecting gear 33. A rotating shaft 34 is arranged in the middle of the connecting gear 33. The other end of the rotating shaft 34 is connected with a first bevel gear 35. Bevel gear 35 is engaged with bevel gear 36 (shown as a gear, actually a bevel gear). A rotating rod 37 is arranged in the middle of the second bevel gear 36 in a penetrating way. One end of the rotating rod 37 is fixedly connected with the chain wheel 10.
In the above arrangement, when the second sliding rod 18 moves, the third sliding rod 27 is driven to move, so as to drive the driving wheel 28 to rotate, and the driving wheel 28 rotates to drive the fixed block 29 to move circularly, so as to slide in the sliding slot 31 and drive the oscillating rod 30 to oscillate back and forth. The swing link 30 swings to slide the driving rod 32 back and forth, so that the rotating shaft 34 rotates. The rotating shaft 34 rotates the rotating rod 37, thereby driving the rotating wheel to rotate back and forth at a certain angle under the reciprocating motion.
Preferably, sensors (not shown in the figure) are arranged at the position of the water outlet pipe 5 and on the outer side of the cleaning machine 1. When the water outlet pipe 5 is connected with the mounting hole 7 in an abutting mode and the sensor on the outer side of the cleaning machine 1 does not sense that the conveying frame 6 moves out of the cleaning machine 1, the sensor transmits a water outlet signal to the water pump, so that the water pump inputs cleaning liquid into the mounting frame 3. When the water outlet pipe 5 is not communicated with the mounting hole 7 or the sensor on the outer side of the cleaning machine 1 senses that the conveying frame 6 moves out of the cleaning machine 1, the water pump stops working.
In addition, it should be noted that the first slide bar 14 and the second slide bar 18 are slidably connected to the driving box 12. The remaining rotating rods 37, the rotating shafts 34 and the rotating parts in the middle of the gears are all connected with the driving box 12 through bearings.
Through the process, the whole cleaning and monitoring process can be realized only by the single driving motor 19, meanwhile, the cleaning and monitoring process can be realized without excessively complicated program design, and meanwhile, the invention can realize the cleaning and monitoring process which is repeated repeatedly, improve the cleaning quality and ensure that no blood remains in the dental handpiece.
For the convenience of understanding the above technical solution, the working principle and working effect thereof are explained in detail through the following working process.
The whole working process is as follows:
1. in the initial state, as shown in fig. 1, the dental handpiece and the transparent dental handpiece model to be cleaned are already installed in the installation hole 7; meanwhile, the lifting plate 8 is located at the highest position, so that the mounting hole 7 is communicated with the water outlet pipe 5, and the water pump is used for discharging water to simultaneously clean the dental handpiece to be cleaned and the transparent dental handpiece model.
2. When the transparent dental handpiece model is observed by human eyes to be higher in cleaning degree, the switch of the driving motor 19 is turned on, so that the driving motor 19 works to drive the second gear 16 to rotate. When the second gear 16 rotates, the first gear 15 and the third gear 17 are driven to rotate in the same direction, so that the first sliding rod 14 and the second sliding rod 18 are driven to move to the position of the cleaning machine 1;
4. when the first slide bar 14 moves, the fixed plate 11 is driven to move, and therefore the conveying frames 6 are driven to move in the same direction. At the moment, the outermost side of the conveying frame 6 is moved out of the cleaning machine 1, so that a sensor on the outer side of the cleaning machine 1 senses a signal, the water pump stops working, at the moment, the mounting hole 7 and the water outlet pipe 5 are changed but are not separated, and the second slide rod 18 drives the extrusion plate 25 on the sliding plate 20 to abut against the pressure expansion pipe 23;
5. when the blood collection device continues to move, the mounting hole 7 and the water outlet pipe 5 are separated under the driving of the chain wheel 10, the extrusion plate 25 extrudes the pressure expansion pipe 23, a liquid outlet gap 24 on the pressure expansion pipe 23 is opened, and part of cleaning liquid in the collection tank 22 contacts with the reagent or the test paper 21, so that whether blood is contained or not is detected. Meanwhile, the rest cleaning liquid is separated from the water outlet pipe 5 through the mounting hole 7, so that the cleaning liquid flows into the water storage tank 2 through the mounting hole 7 and the collecting tank 22 to be collected. At this time, the liquid level in the water storage tank 2 gradually rises, and the chain 9 drives the lifting plate 8 to be positioned at the position of the lowest point.
6. When the water outlet pipe 5 continuously moves on the basis of the step 5, the extrusion plate 25 penetrates through the pressure expansion pipe 23 and does not abut against the pressure expansion pipe 23 any more, the liquid outlet seam 24 is closed, meanwhile, the conveying frame 6 completely moves out of the cleaning machine 1, the chain 9 drives the lifting plate 8 to move upwards under the reverse rotation of the chain wheel 10, so that the water outlet pipe 5 is lifted, and the cleaning liquid in the water storage tank 2 is placed to contact with the water outlet pipe 5 to pollute the water outlet pipe 5.
7. An external medical worker can conveniently judge whether the dental handpiece is completely cleaned or not by observing the cleaning state of the transparent dental handpiece model and indicating whether blood components are contained on the reagent or the test paper 21; and if the dental handpiece is completely cleaned, taking out the cleaned dental handpiece for dental medical work, and if the dental handpiece is not completely cleaned, reversing the steps and carrying out secondary cleaning.
8. And if the dental handpiece is completely cleaned, reloading a new dental handpiece to be cleaned and the transparent dental handpiece model injected with the artificial blood into the mounting hole 7, replacing the test paper 21 or the reagent, reversely carrying out the steps 1-6, and when the conveying frame 6 completely returns to the original position, starting the water pump to work and inputting a cleaning liquid to clean the dental handpiece.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
