The gear 11 is meshingly connected with the gear ring 10. A micro motor 12 is fixedly installed inside the storage tube 1, and the output end of the micro motor 12 is fixedly connected to the right side of the gear 11. By setting the gear ring 10 and the gear 11, the micro motor 12 is started to drive the gear 11 to rotate, and the gear ring 10 is rotated through the meshing connection between the gear 11 and the gear ring 10. The fixed connection between the gear ring 10 and the spline sleeve 8 provides a driving force for the rotation of the spline sleeve 8;

[0050] Reference Figure 1-9 The interior of the accommodating chamber 401 is fixedly installed with a limit rod 13, and the interior of the accommodating chamber 401 is rotatably installed with a bidirectional screw rod 14. The telescopic ring 403 is slidably sleeved on the surface of the limit rod 13. The telescopic ring 403 and the bidirectional screw rod 14 are threadedly connected. By setting the limit rod 13 and the bidirectional screw rod 14, the bidirectional screw rod 14 is rotated. Since the telescopic ring 403 is sleeved on the surfaces of the bidirectional screw rod 14 and the limit rod 13, and the threaded connection between the telescopic rod 301 and the bidirectional screw rod 14 makes the telescopic ring 403 move to the left, thereby driving the telescopic rod 301 to move to the left through the telescopic ring 403, so that the telescopic ring 403 drives the first fixing ring 302 and the second fixing ring 305 to extend from the inner cavity of the storage tube 1;

[0051] Reference Figure 1-9The left side of the handle 2 is open, and a first spring 15 is fixedly installed on the right side of the inner wall of the handle 2. A telescopic plate 16 is fixedly installed on the left side of the first spring 15. A driving bar 17 is fixedly installed on the top of the telescopic plate 16. The shape of the driving bar 17 is set to be L-shaped. The vertical end of the driving bar 17 is sleeved on the surface of the bidirectional screw rod 14, and the driving bar 17 and the bidirectional screw rod 14 are threadedly connected. By setting the telescopic plate 16, the staff first removes the closing cap 6, holds the handle 2, and holds the telescopic plate 16 at the same time, so that the telescopic plate 16 moves in the direction close to the handle 2, and the telescopic plate 16 is retracted into the inner cavity of the handle 2. The telescopic plate 16 and the driving bar 17 are fixedly connected, so that the telescopic plate 16 drives the driving bar 17 to move rightward. Since the driving bar 17 is sleeved on the surface of the bidirectional screw rod 14 and is threadedly connected to the bidirectional screw rod 14, the driving bar 17 drives the bidirectional screw rod 14 to rotate when it moves rightward, and the driving bar 17 and the telescopic ring 403 are respectively located on the two sides of the thread direction of the bidirectional screw rod 14 in opposite directions, so that the bidirectional screw rod 14 can automatically drive the telescopic ring 403 to move leftward at this time, so that the staff can just hold the telescopic plate 16 when using it, and then drive the telescopic rod 301 to drive the first fixed ring 302 and the second fixed ring 305 to automatically protrude from the inner cavity of the storage tube 1;

[0052] Reference Figure 1-9 The inside of the storage tube 1 is fixedly installed with an anti-rotation rod 18, and the surface of the anti-rotation rod 18 is slidably sleeved with a delivery tube 19. The left side of the delivery tube 19 is opened, and the surface of the delivery tube 19 is provided with a limiting groove 20. The right side wall of the spline shaft 9 is sleeved on the surface of the limiting groove 20. By setting the limiting groove 20, when the spline shaft 9 moves to the left or right, the right side wall of the spline shaft 9 and the limiting groove 20 cooperate to drive the delivery tube 19 to move to the left or right at the same time, and through the cooperation of the anti-rotation rod 18, when the spline shaft 9 rotates, it will not drive the delivery tube 19 to rotate together;

[0053] Reference Figure 1-9Two infusion bottles 21 are threadedly installed on the top of the storage tube 1. The two infusion bottles 21 are respectively located above the two fixed boxes 501. The bottle mouths of the infusion bottles 21 penetrate into the interior of the fixed box 501. A return plate 22 is fixedly sleeved on the surface of the puncture needle 503. A second spring 23 is fixedly installed on the bottom of the return plate 22. The other end of the second spring 23 is fixedly connected to the top of the fixed frame 502. An infusion port 24 is provided on the top of the delivery tube 19. Two movable cavities 25 are provided on the top of the delivery tube 19. A third spring 26 is fixedly installed on the bottom of the inner wall of the movable cavity 25. An extrusion buckle 27 is fixedly installed on the other end of the third spring 26. By setting the second spring 23, the infusion bottles 21 The infusion bottle 21 can be fixed on the top of the storage tube 1 by threaded connection. When the infusion bottle 21 is fixed, the bottom of the infusion bottle 21 penetrates into the interior of the fixing box 501, and at this time, the puncture needle 503 is located just below the bottle mouth of the infusion bottle 21. When the staff holds the handle 2, the telescopic plate 16 is squeezed to make the telescopic rod 301 protrude from the inner cavity of the storage tube 1, and at the same time, the delivery tube 19 is driven to move to the left. The squeezing buckle 27 on the delivery tube 19 is squeezed by the bottom of the fixing box 501 and retracts into the interior of the moving cavity 25. Since the bottom of the fixing box 501 is open, when the squeezing buckle 27 is located below the opening, it pops out by the rebound force of the third spring 26. Since the elastic force of the third spring 26 is greater than the elastic force of the second spring 23, the puncture needle 5 03 is squeezed by the squeezing buckle 27 and moves upward. The liquid inside the infusion bottle 21 on the left is a cleaning liquid specially used for cleaning the patient's mouth, and the liquid inside the infusion bottle 21 on the right is a cleaning liquid specially used for cleaning the nursing institution, so that the two puncture needles 503 pierce the plastic films at the bottle mouths of the two infusion bottles 21 at the same time. After the liquid flows into the interior of the fixed box 501, due to the good sealing between the fixed box 501 and the delivery tube 19, the liquid will not leak until the telescopic rod 301 moves to the left to the preset position, the first fixing ring 302 and the second fixing ring 305 are completely extended, and at this time the infusion port 24 moves to the bottom of the left fixed box 501, and the cleaning liquid in the left fixed box 501 enters the interior of the delivery tube 19 through the infusion port 24, and passes through The cleaning fluid is sprayed out from the cleaning tank 7 by the rotation of the telescopic rod 301. When the patient's oral cleaning is completed and the cleaning mechanism needs to be cleaned, the staff releases the telescopic plate 16 at this time, and the telescopic plate 16 returns to its original position through the resilience of the first spring 15. On the contrary, the telescopic ring 403 drives the telescopic rod 301 and the delivery tube 19 back to their original positions, so that the infusion port 24 is located below the right fixed box 501, so that the cleaning fluid inside the right fixed box 501 enters the inside of the delivery tube 19, and the closing cap 6 is installed on the left side of the receiving tube 1 to put the receiving tube 1 in a closed state. Similarly, the staff can start the micro motor 12 to make the telescopic rod 301 drive the first fixed ring 302 and the second fixed ring 305 to rotate. At this time, since the inner cavity of the receiving tube 1 is closed,The nursing mechanism is made to perform self-cleaning. After completion, the sealing cap 6 is removed and the cleaning liquid is poured out.

[0054] Specifically, the working process or working principle of the oral care device is as follows: when in use, the two infusion bottles 21 are respectively installed on the top of the two storage tubes 1, the staff removes the closing cap 6, holds the handle 2, and holds the telescopic plate 16 at the same time, so that the telescopic plate 16 moves in the direction close to the handle 2, and the telescopic plate 16 is retracted into the inner cavity of the handle 2. Due to the fixed connection between the telescopic plate 16 and the driving bar 17, the telescopic plate 16 drives the driving bar 17 to move right. Since the driving bar 17 is sleeved on the surface of the bidirectional screw rod 14 and is threadedly connected to the bidirectional screw rod 14, the driving bar 17 drives the bidirectional screw rod 14 to rotate when it moves to the right, and the driving bar 17 and the telescopic ring 403 are respectively located on the two sides of the bidirectional screw rod 14 with opposite thread directions, so that at this time the bidirectional screw rod 14 can automatically drive the telescopic ring 403 to move leftward. Through the cooperation of the telescopic ring 403 and the telescopic groove 402, the telescopic rod 301 moves leftward, and at the same time drives the delivery tube 19 to move leftward. The squeezing buckle 27 on the delivery tube 19 is squeezed by the bottom of the fixed box 501 and retracts into the inside of the moving cavity 25. Since the bottom of the fixed box 501 is set as an opening, when the squeezing buckle 27 is located below the opening, it pops out by the rebound force of the third spring 26. Since the elastic force of the third spring 26 is greater than the elastic force of the second spring 23, the puncture needle 503 is squeezed by the squeezing buckle 27 and moves upward. The liquid inside the infusion bottle 21 on the left is a cleaning liquid specially used for cleaning the patient's mouth, and the liquid inside the infusion bottle 21 on the right is a cleaning liquid specially used for cleaning the nursing institution. The two puncture needles 503 pierce the plastic films at the mouths of the two infusion bottles 21 at the same time. After the liquid flows into the interior of the fixed box 501, the liquid will not leak due to the good sealing between the fixed box 501 and the delivery tube 19, until the telescopic rod 301 moves to the left to the preset position, the first fixed ring 302 and the second fixed ring 305 are completely extended, and the infusion port 24 moves to the bottom of the left fixed box 501. The cleaning liquid in the left fixed box 501 enters the interior of the delivery tube 19 through the infusion port 24, and the micro motor 12 is started to drive the gear 11 to rotate. The meshing connection between the gear 11 and the ring gear 10 makes the ring gear 10 rotate, and the fixed connection between the ring gear 10 and the spline sleeve 8 provides a drive for the rotation of the spline sleeve 8. Force, due to the sliding arrangement between the spline shaft 9 and the spline sleeve 8, and the cooperation of the healthy teeth between the spline shaft 9 and the spline sleeve 8, the spline sleeve 8 can drive the telescopic rod 301 to rotate through the spline shaft 9, and the rotation of the telescopic rod 301 drives the first fixed ring 302 and the second fixed ring 305 to rotate, so that the first bristles 303, the second bristles 304, the third bristles 306 and the fourth bristles 307 rotate. The staff manually controls the angle to clean the patient's oral cavity in all directions, and at the same time, the cleaning liquid used for oral cleaning is sprayed from the cleaning tank 7 through the centrifugal force of the rotation. When the patient's oral cavity is cleaned and the cleaning mechanism needs to be cleaned, the staff releases the telescopic plate 16 at this time, and the resilience of the first spring 15 makes the telescopic plate 16 return to its original position.On the contrary, at this time, the telescopic ring 403 drives the telescopic rod 301 and the delivery tube 19 back to the original position, so that the infusion port 24 is located below the right fixed box 501, so that the cleaning liquid inside the right fixed box 501 enters the inside of the delivery tube 19, and the closing cap 6 is installed on the left side of the storage tube 1 to make the storage tube 1 in a closed state. Similarly, the staff can start the micro motor 12 to make the telescopic rod 301 drive the first fixed ring 302 and the second fixed ring 305 to rotate. At this time, since the inner cavity of the storage tube 1 is closed, the nursing mechanism performs self-cleaning. After completion, the closing cap 6 is removed and the cleaning liquid is poured out.
