DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

[0030] See also Figure 1-Figure 8 In one embodiment of the present application, a dental suction machine with a detachable suction port structure includes a base 1, a control box 2, a mounting frame 3, a water tank 4, a frame 11 and a plurality of air pumps 12, wherein the control box 2, the mounting frame 3 and the frame 11 are all arranged on the base 1, the water tank 4 is arranged on the mounting frame 3, a plurality of the air pumps 12 are arranged on the frame 11, a fixing seat 34 connected to the air pump 12 is arranged on the frame 11, the air pump 12 is connected to the water tank 4 through an input pipe 35, a water level monitoring pipe 6 is arranged on the water tank 4, the dental suction machine also includes a suction head assembly, a bellows 8 connecting the suction head assembly and the air pump 12 is arranged on the base 1, and the suction head assembly is used to receive oral excrement;

[0031] The suction head assembly includes a mounting head 13, a matching joint 14, a suction tube 17 and a conical receiving module. The mounting head 13 is connected to the bellows 8. The matching joint 14 is provided with an external thread on its outer wall. The mounting head 13 is provided with an internal thread matching with the matching joint 14 on its inner wall. The suction tube 17 is provided on the matching joint 14. The conical receiving module is provided on the suction tube 17 to adjust the receiving range of the suction tube 17 for oral excrement.

[0032] In this exemplary embodiment, a placement rack 5 is provided on the base 1 , and a placement groove matching with the mounting head 13 is provided on the placement rack 5 .

[0033] When oral treatment is required for the patient, the suction head assembly is taken out from the display rack 5, and the suction head assembly is fixed on one side of the patient's mouth. When dental surgery is performed on the patient's mouth, the receiving range of the conical receiving module is adjusted according to the size of the patient's mouth, so as to fully absorb the oral excrement. The control box 2 controls one of the air pumps 12 to work. When the air pump 12 works, the excrement in the patient's mouth can be discharged into the bellows 8 along the conical receiving module, and finally the oral excrement is discharged into the water tank 4 along the input pipe 35. The water level in the water level monitoring pipe 6 can be observed to feedback the water storage amount in the water tank 4.

[0034] See also Figure 1-Figure 7 As another preferred embodiment of the present application, the conical receiving module includes a conical structure, a driving structure and an adjusting structure. The conical structure is a deformable structure. The conical structure includes at least a large diameter end and a small diameter end. The small diameter end of the conical structure is connected to the suction tube 17. The driving structure is arranged in the fitting 14 and connected to the conical structure. The adjusting structure is arranged on the mounting head 13 and connected to the driving structure. When the adjusting structure is working, it controls the operation of the driving structure and adjusts the diameter of the large diameter end of the conical structure.

[0035] In a specific case of this embodiment, the conical structure includes a plurality of embedded balls 20, a plurality of split strips 15 and an elastic rubber skin 16. A plurality of embedded grooves 23 are arranged around the side of the suction tube 17 away from the fitting 14. The embedded balls 20 and the embedded grooves 23 are adapted and slidably embedded in the embedded grooves 23. Each of the embedded balls 20 is provided with a split strip 15. The split strip 15 and the suction tube 17 are elastically connected. A mounting groove 33 is formed in the split strip 15. The elastic rubber skin 16 is provided with a plurality of embedded balls 20. The rubber skin 16 is conical and passes through the mounting groove 33 of each split strip 15. The split strip 15 is provided with a notch 21 for the small diameter end of the elastic rubber skin 16 to pass through the mounting groove 33. The small diameter end of the elastic rubber skin 16 is sleeved on the outer wall of the suction tube 17. A locking sleeve 18 is provided on the outer wall of the suction tube 17. The elastic rubber skin 16 is clamped between the locking sleeve 18 and the suction tube 17. The driving structure adjusts the angle between the split strip 15 and the suction tube 17 when working.

[0036] In another specific case of the present embodiment, the driving structure includes an adjusting ring 22, a connecting shaft 24, a movable ring 25 and a connecting head 27. The adjusting ring 22 is movably arranged on the inner side of the elastic rubber skin 16. The adjusting ring 22 and the split strip 15 are slidably matched. The connecting shaft 24 is movably arranged on the inner side of the matching joint 14 and one end is connected to the adjusting ring 22. The movable ring 25 is movably arranged on the inner side of the mounting head 13 and is connected to the other end of the connecting shaft 24. The connecting head 27 is arranged on the movable ring 25. The connecting shaft 24 and the matching joint 14 are elastically connected. The connecting head 27 is connected to the adjusting structure. The adjusting structure adjusts the position of the connecting head 27 when working.

[0037] When it comes to patients with different oral sizes, the adjustment structure is controlled to work, thereby driving the connector 27 to move relative to the matching connector 14. When the connector 27 moves, the connecting shaft 24 can be used to drive the adjustment ring 22 and the movable ring 25 to move. Under the interference between the adjustment ring 22 and the split strip 15, the embedded ball 20 rotates in the embedded groove 23, thereby adjusting the angle between the split strip 15 and the suction tube 17. Since the elastic rubber skin 16 is an elastically stretchable structure, the angle between the split strip 15 and the suction tube 17 is changed. When the elastic rubber skin 16 changes, the elastic rubber skin 16 is deformed, thereby changing the diameter of the large diameter end formed by the split strip 15 and the elastic rubber skin 16, thereby facilitating dental treatment for patients with oral cavity of different sizes, ensuring that oral excrement is fully absorbed by the suction tube 17, and when the suction tube 17 needs to be cleaned later, by disengaging the connecting head 27 from the adjustment structure and rotating the fitting 14, the threaded cooperation between the fitting 14 and the mounting head 13 facilitates the disassembly of the fitting 14 and the suction tube 17 for cleaning.

[0038] See also Figure 1-Figure 7As another preferred embodiment of the present application, the adjustment structure includes a locking rod 28, a movable sleeve 19 and an adjusting sleeve 29. The locking rod 28 is movable and passes through the mounting head 13. The movable sleeve 19 is movably mounted on the outer wall of the mounting head 13. The locking rod 28 and the movable sleeve 19 are detachably connected. The adjusting sleeve 29 is movably mounted on the outer wall of the mounting head 13. The adjusting sleeve 29 and the movable sleeve 19 are movably connected. The connecting head 27 is provided with a connecting hole 26 for the locking rod 28 to pass through.

[0039] In this exemplary embodiment, a guide groove is formed on the movable sleeve 19 , and movable bars are symmetrically and movably arranged in the guide groove. The movable bar is L-shaped and one end away from the guide groove is connected to the adjustment sleeve 29 .

[0040] It should be noted that the present embodiment is not limited to the above-mentioned adjustment structure to adjust the position of the movable ring 25, and a linear motor, an electric cylinder or a pneumatic cylinder may also be directly used instead, which are not listed here one by one.

[0041] When encountering different oral sizes of patients, by rotating the adjusting sleeve 29, the adjusting sleeve 29 can be driven to move along the mounting head 13 under the action of the threaded cooperation between the adjusting sleeve 29 and the mounting head 13, so that the movable sleeve 19 and the locking rod 28 can be pushed to move synchronously by the movable bar, thereby driving the connecting head 27 and the adjusting ring 22 to move. Under the action of the resistance between the adjusting ring 22 and the split strip 15 and the elastic restoring force between the split strip 15 and the suction tube 17, the angle between the adjusting ring 22 and the suction tube 17 can be changed to achieve the diameter size of the large diameter end of the elastic rubber skin 16.

[0042] See also Figure 1 as well as Figure 8 As another preferred embodiment of the present application, an impurity box 10 is provided in the water tank 4, and the dental suction machine also includes a solid-liquid separation component, which is arranged on the base 1 and connects the air pump 12, the water tank 4 and the impurity box 10, and is used to discharge solid impurities and liquid impurities into the impurity box 10 and the water tank 4 respectively.

[0043] In a specific case of the present embodiment, the solid-liquid separation component includes a separation box 7, a discharge pipe 9 and a separator. The number of the separation boxes 7 is the same as the number of the air pumps 12 and they are arranged on the base 1. The separation box 7 is connected to the air pump 12 through the input pipe 35. The separation box 7 is provided with an output port No. 1 and an output port No. 2. The output port No. 1 is connected to the impurity box 10, and the output port No. 2 is connected to the water tank 4 through the discharge pipe 9. The separator is arranged in the separation box 7 and connects the output port No. 1 to the input pipe 35, so as to separate solid impurities and liquid impurities in the oral excrement passing through.

[0044] In another specific case of this embodiment, the separation element includes a spiral tube 30, a spiral groove 31 and a gauze 32. The spiral tube 30 is arranged in the separation box 7. The spiral groove 31 and the spiral tube 30 are adapted in shape and are arranged on the spiral tube 30. The gauze 32 is arranged in the spiral groove 31. The spiral tube 30 connects the input pipe 35 and the first output port.

[0045] When the air pump 12 is used to work and the excrement in the oral cavity is sucked into the suction tube 17, the excrement can be discharged into the spiral tube 30 along the input tube 35. Since the spiral tube 30 is spiral-shaped, the excrement will generate centrifugal force when the spiral motion in the spiral tube 30 along with the airflow causes the excrement to move toward the inner wall of the spiral tube 30. By arranging a spiral groove 31 and a gauze 32 on the spiral tube 30, liquid impurities can be discharged from the spiral tube 30 along the gauze 32 and enter the separation box 7. Finally, solid impurities can follow the airflow along the spiral tube 30 and the No. 1 output port into the impurity box 10, and liquid impurities can fall into the separation box 7 and be discharged into the water tank 4 along the discharge pipe 9.

[0046] How this application works:

[0047] When oral treatment is required for the patient, the suction head assembly is taken out from the display rack 5 and fixed on one side of the patient's mouth. When dental surgery is performed on the patient's mouth, when encountering different oral sizes of patients, the adjusting sleeve 29 is rotated. Under the action of the threaded cooperation between the adjusting sleeve 29 and the mounting head 13, the adjusting sleeve 29 can be driven to move along the mounting head 13, so that the movable bar is used to push the movable sleeve 19 and the locking rod 28 to move synchronously, thereby driving the connecting head 27 and the adjusting ring 22 to move. Under the action of the resistance between the adjusting ring 22 and the split strip 15 and the elastic restoring force between the split strip 15 and the suction tube 17, the angle between the adjusting ring 22 and the suction tube 17 can be changed to achieve the diameter size of the large diameter end of the elastic rubber skin 16. In this way, oral excrement can be fully absorbed. One of the air pumps 12 is controlled to work through the control box 2. When the air pump 12 is used to work and the excrement in the oral cavity is sucked into the suction tube 17, the excrement can be discharged into the spiral tube 30 along the input tube 35. Since the spiral tube 30 is spiral-shaped, the excrement will generate centrifugal force when the airflow spirals in the spiral tube 30, causing the excrement to move toward the inner wall of the spiral tube 30. By arranging a spiral groove 31 and a gauze 32 on the spiral tube 30, liquid impurities can be discharged from the spiral tube 30 along the gauze 32 and enter the separation box 7. Finally, solid impurities can follow the airflow along the spiral tube 30 and the No. 1 output port into the impurity box 10, and liquid impurities can fall into the separation box 7 and be discharged into the water tank 4 along the discharge pipe 9.

Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
