The bottom surface of the gas barrier 14 is provided with a circular truncated hole, and the side of the circular truncated hole with a smaller diameter is upward , The inner wall of the air barrier 14 is fixedly connected with a spring A16, the top of the spring A16 is fixedly connected with a round plate 15 which is attached to the inner wall of the air barrier 14, and the bottom surfaces of the two air barriers 14 are fixedly connected with a circle Cylinder 13, the cylinder 13 is a hollow cylinder and is connected with two gas barriers 14. The two sides of the bottom surface of the cylinder 13 are also fixedly connected and communicated with the gas barriers 14, and the inner wall of the cylinder 13 is sleeved with a piston A17, the piston A17 is made of metal, the middle outer wall of the cylinder 13 is sleeved with a slip ring 18, the slip ring 18 is made of a strong magnet, and the piston A17 is attracted by the slip ring 18.
[0046] A rotating motor 22 is fixedly installed under the table board 1, and the rotating motor 22 is electrically connected to the control panel 8. The drive shaft of the rotating motor 22 is fixedly connected with a turntable 23. The outer edge of the front of the turntable 23 is fixedly connected with a round rod 24. A connecting rod 25 is sleeved on the outer wall of 24. The connecting rod 25 is rectangular and has an elliptical hole on the front. The top surface of the connecting rod 25 is fixedly connected with a splint 19, which is a C-shaped body, and the inner wall of the splint 19 is The ring 18 is sleeved, and when the air barrier 14 is in an upright state, the rotating motor 22 is controlled by the control panel 8 to start, and the drive shaft of the rotating motor 22 drives the turntable 23 to rotate. The turntable 23 passes through the sleeve of the round rod 24 and the connecting rod 25. The connection drives the splint 19 to rotate. The splint 19 keeps the inner wall upward through the sleeve connection with the slip ring 18 and drives the slip ring 18 to slide left and right. When the slip ring 18 slides left and right, the magnetic force drives the piston A17 to slide left and right, and the piston A17 will squeeze when sliding left and right. Press the air in the cylinder 13 on one side and generate negative pressure in the cylinder 13 on the other side. The compressed air pushes the upper circular plate 15 to close the air barrier 14 and pushes the lower circular plate 15 to expand the air barrier 14. Thereby the air in the cylinder 13 is discharged, the negative pressure pushes the lower round plate 15 to close the air barrier 14 and pulls the upper round plate 15 to expand the air barrier 14, and then the negative pressure draws the baffle through the connecting pipe 12 and the sleeve 3. 4, and then the baffle 4 draws outside air through the loudspeaker tube 9. Through the setting of the cylinder 13, the outside air is drawn through the loudspeaker tube 9 after the rotating motor 22 is started, and the air corresponding to the patient side is drawn in. Prevent saliva and other infectious sources from floating in the air, further reducing the risk of disease transmission, and through the effect of multiple sets of loudspeakers 9, increase the range of air inhalation, and further prevent saliva and other infectious sources from floating in the air through the cylinder The setting of 13 uses the left and right shaking of the piston A17 to achieve a state of uninterrupted air extraction, ensuring the effect of extracting infectious sources such as patient saliva, so as to maximize the risk of virus floating in the air. Through the setting of cylinder 13, Utilizing the air extraction effect to accelerate the circulation of air near the loudspeaker tube 9 has the effect of generating wind current near the patient, reducing the patient's body temperature raised due to tension, and using wind current to blow the patient’s cheeks to encourage the patient to calm down, which is beneficial to improve the patient’s health Comfort.
[0047] The bottom surface of the baffle 4 is fixedly connected to the bottom plate 10, and the top surface of the bottom plate 10 is laid with holes. The bottom plate 10 is provided to fill the hollow of the bottom surface when the baffle 4 is contained in the sleeve 3, ensuring that the baffle 4 and the sleeve When the barrel 3 is ventilated, the problem of sundries falling into the baffle 4 is avoided, and the normal use of the table 1 after the baffle 4 is contained in the sleeve 3 is ensured.
[0048] The inner walls of the two air barriers 14 located below are provided with threaded grooves and are threadedly connected with a filter barrel 20. The inner wall of the filter barrel 20 is fixedly connected with three sets of filter plates 21. The front of the filter barrel 20 is provided with holes under the filter plate 21. The user can communicate with the hole on the front of the filter barrel 20 through a pipe, and then connect the pipe to an air purification device. The air discharged from the cylinder 13 will be filtered by the filter plate 21 to filter out impurities and saliva in the air. The filtered air is discharged through the filter bucket 20. Through the setting of the filter bucket 20, the air near the patient discharged from the cylinder 13 is filtered, and the filtered air is discharged in a concentrated manner to prevent the air from floating with virus-containing saliva when the cylinder 13 discharges the air. After use, the doctor removes the filter barrel 20 and then takes out the filter plate 21 to detect the impurities and saliva filtered by the filter plate 21 to detect whether the patient carries the virus.
[0049] A movable cylinder 26 is fixedly connected to the back side of the sleeve 3, and the movable cylinder 26 is a rectangular body with a hollow top surface and a front surface, and the movable cylinder 26 communicates with the inside of the sleeve 3, and the front inner wall of the movable cylinder 26 is fixedly connected with a cylinder plate 27 , The front of the cylinder plate 27 is flush with the inner wall of the back side of the sleeve 3, the bottom end of the movable cylinder 26 is provided with a hole and a rotating rod A28 is sleeved in the hole, and the end of the rotating rod A28 located in the movable cylinder 26 is fixedly connected with the rotating Column 29, the outer wall of the rotating column 29 is fixedly connected with twenty fan blades 30 at equal intervals, and the bottom end of the back side of the cylinder plate 27 is fixedly connected with an air duct 31, which is a hollow J-shaped body and is connected to the sleeve 3. The air duct 31 is located inside the movable cylinder 26. The end of the air duct 31 away from the cylinder plate 27 corresponds to the fan blade 30. The back side of the movable cylinder 26 is provided with a hole above the back side of the rotating column 29, and the bottom surface of the table 1 corresponds to the movable cylinder. There is a slot at the position 26 and the rotating rod B34 is located in the slot. The left end of the rotating rod B34 and the right side of the rotating column 29 are fixedly connected with a pulley 32. The two pulleys 32 are connected by a belt 33, and the baffle 4 is housed in the sleeve. When the cylinder 3 is inside, the rotating motor 22 is activated to make the cylinder 13 pump air. The cylinder 13 is pumped from the gap between the baffle 4 and the sleeve 3 through the air duct 31. The air duct 31 corresponds to the setting of the fan blade 30. 31. The air flow generated by the suction will be driven by the fan blade 30 to rotate the rotating column 29. After the rotating column 29 rotates, the pulley 32 and the belt 33 drive the rotating rod B34 to rotate, thereby driving the baffle 4 to rotate at a certain angle until the cylinder 13 passes the baffle 4 For air extraction, through the setting of the movable cylinder 26, the air extraction effect of the cylinder 13 drives the baffle 4 to turn over a certain angle from the sleeve 3, thereby assisting the doctor to stand up the baffle 4, and press the baffle 4 with one hand and raise it with the other hand The operation steps of the baffle 4 are simplified as directly lifting the baffle 4, which is beneficial to improve the operating efficiency. Moreover, turning the baffle 4 at a certain angle is convenient for doctors to apply force. Compared with lifting the baffle 4 from the inner diameter of the sleeve 3 In this way, the doctor’s physical exertion can be reduced.
