[0056] The motor 15 is controlled to drive the first gear 16 outside its output shaft to rotate, and the meshing action between the two first gears 16 drives the main shaft 14 to rotate, and then drives the turntable 13 to rotate. The four processing tanks 5 on the top of the turntable 13 revolve around the main shaft 14, wherein the motor 15 is controlled to drive the main shaft 14 and the turntable 13 to pause every quarter turn, and then drives the gas injection pipes 6 on the four processing tanks 5 to rotate in turn to the bottom of the sealing sleeve 10, so as to establish a sealed connection with the intake pipe 8 in turn.

[0057] The gas control mechanism is arranged inside the processing tank 5 and is used for controlling the continuous injection of anesthetic waste gas into the solution. The gas control mechanism includes a partition 17 fixedly connected to the processing tank 5, two control cylinders 18 installed on the top of the partition 17 and a gear ring 19 fixedly connected to the inside of the box body 1; an air guide tube 20 is installed on the outer wall of one side of the processing tank 5, and a third solenoid valve 21 is installed on the air guide tube 20; a liquid guide tube 22 is installed at the bottom of the processing tank 5, and a fourth solenoid valve 23 is installed on the liquid guide tube 22, and pistons 24 are installed inside the two control cylinders 18; a lifting assembly is installed on the top of one of the control cylinders 18; a spring 25 is fixedly connected to the inner wall of the top of the other control cylinder 18, and the bottom end of the spring 25 is fixedly connected to the top of the piston 24; the two control cylinders 18 are connected to the gas injection pipe 6 through a reflux assembly. The lifting assembly includes a driven shaft 26 rotatably connected to the top of the processing tank 5, a reciprocating screw 27 fixedly sleeved on the outside of the driven shaft 26, and a second gear 28 fixedly connected to the top of the driven shaft 26; the second gear 28 is located on the inner side of the gear ring 19 and meshes with the gear ring 19; a lifting block 29 is screwed to the outside of the reciprocating screw 27, and a plurality of lifting rods 30 are fixedly connected to the bottom of the lifting block 29, and the bottom ends of the plurality of lifting rods 30 are all slidably extended to the inside of the control cylinder 18, and the bottom ends of the plurality of lifting rods 30 are fixedly connected to the pusher block 31, and the reflux assembly includes a first reflux pipe 32 installed at the bottom of the control cylinder 18 and a second reflux pipe 33 installed between the first reflux pipe 32 and the gas injection pipe 6; a fifth solenoid valve 34 is installed on the first reflux pipe 32; a sixth solenoid valve 35 is installed on the second reflux pipe 33;

[0058] After the anesthetic waste gas enters the solution, the pressure in the bottom area of ​​the partition 17 increases, and the fifth solenoid valve 34 on the left is controlled to open. The anesthetic waste gas at the bottom of the partition 17 that has been treated by the solution once enters the inside of the control cylinder 18 on the left through the first reflux pipe 32 on the left, thereby driving the piston 24 on the left to move upward along the inner wall of the control cylinder 18 until the top of the piston 24 abuts against the bottom of the push block 31, so that the anesthetic waste gas injected into the processing tank 5 is temporarily stored in the inside of the control cylinder 18 on the left, and the fifth solenoid valve 34 on the left is controlled to be closed, and the sixth solenoid valve 35 on the left is opened. In the process of the turntable 13 rotating a quarter of a turn, the second gear 28 is used to control the anesthetic waste gas injected into the processing tank 5. The meshing effect between the gear ring 19 drives the driven shaft 26 to rotate, and the reciprocating screw 27 rotates accordingly. In this process, the lifting block 29 is driven to move down from the top end of the reciprocating screw 27 to its bottom end, thereby driving the push block 31 to move downward through the lifting rod 30, and then driving the piston 24 on the left to move downward, and the anesthetic waste gas inside the left control cylinder 18 is injected into the gas injection pipe 6 again through the second return pipe 33 on the left, and is injected into the solution again through each shunt pipe 41, so that the anesthetic waste gas is subjected to secondary purification. At this time, the fifth solenoid valve 34 on the right is in an open state, so that the anesthetic waste gas re-injected into the solution enters through the first return pipe 32 on the right The spring 25 is compressed accordingly, and as the turntable 13 continues to rotate a quarter of a turn, the reciprocating screw 27 is driven to continue to rotate, and the lifting block 29 is driven to move from the bottom end of the reciprocating screw 27 to the top end thereof. In this process, the pusher block 31 is driven to move upward. At this time, the fifth solenoid valve 34 on the right and the sixth solenoid valve 35 on the left are in a closed state, and the sixth solenoid valve 35 on the right and the fifth solenoid valve 34 on the left are in an open state. Therefore, when the pusher block 31 is driven to move upward and does not limit the top of the left piston 24, the rebound force of the spring 25 drives the piston 24 on the right to move upward. 4 moves downward, injects the anesthetic waste gas in the right control cylinder 18 into the gas injection pipe 6 again through the second return pipe 33, and injects it into the solution again through the shunt pipes 41, performs three purification treatments on the anesthetic waste gas, and re-injects the anesthetic waste gas into the solution, enters the left control cylinder 18 through the first return pipe 32 on the left, and drives the left piston 24 to move upward again. When the turntable 13 is driven to rotate a quarter of a circle, after the anesthetic waste gas is purified four times, the third solenoid valve 21 is controlled to open, and the fully treated anesthetic waste gas in the processing tank 5 is discharged to the inside of the box body 1 through the air guide pipe 20, and finally discharged through the exhaust pipe 3 and the filter 4;

[0059] When the solution in the processing tank 5 needs to be replaced, the fourth solenoid valve 23 is controlled to open, and the solution in the processing tank 5 is discharged through the liquid guide tube 22 and finally discharged through the liquid discharge tube 40 .

[0060] The main shaft 14 is also connected to a feeding mechanism. The main shaft 14 is a hollow structure. The feeding mechanism includes a plurality of liquid adding pipes 36 installed on the outer wall of the main shaft 14, a rotary sealing joint 37 rotatably connected to the top of the main shaft 14, and a liquid injection pipe 38 installed on the top of the rotary sealing joint 37. The rotary sealing joint 37 is set so that when the main shaft 14 rotates, the liquid injection pipe 38 does not rotate therewith; the plurality of liquid adding pipes 36 are respectively connected to the plurality of processing tanks 5, and a seventh solenoid valve 39 is installed on the liquid adding pipe 36; a liquid discharge pipe 40 is installed at the bottom of the box body 1;

[0061] After the solution in the processing tank 5 is discharged, the seventh solenoid valve 39 is opened, and the solution is added to the spindle 14 through the injection pipe 38, and the solution is added to the processing tank 5 through each filling pipe 36. After the solution is replaced, the seventh solenoid valve 39 is controlled to be closed.

[0062] Working principle: When in use, when one of the gas injection pipes 6 rotates to the position directly below the sealing sleeve 10, the cylinder 9 is controlled to extend, driving the connecting block 12 and the sealing sleeve 10 to move downward, so that the sealing sleeve 10 is sleeved on the outside of the top of the gas injection pipe 6, thereby establishing a connection between the air intake pipe 8 and the gas injection pipe 6. By opening the second solenoid valve 11 and the first solenoid valve 7, the anesthetic waste gas is dispersedly injected into the solution through the air intake pipe 8, the gas injection pipe 6 and the shunt pipes 41 through the exhaust structure 2, so that the anesthetic waste gas contacts the solution and removes harmful substances in the anesthetic waste gas. This is a primary purification treatment of the anesthetic waste gas. After the anesthetic waste gas enters the solution, the pressure in the bottom area of ​​the partition 17 increases, and the fifth solenoid valve 34 on the left is controlled to open, and the bottom of the partition 17 is treated once by the solution The anesthetic waste gas enters the control cylinder 18 on the left through the first reflux pipe 32 on the left, thereby driving the piston 24 on the left to move upward along the inner wall of the control cylinder 18 until the top of the piston 24 abuts against the bottom of the pusher block 31, so that the anesthetic waste gas injected into the processing tank 5 is temporarily stored in the control cylinder 18 on the left, controlling the fifth solenoid valve 34 on the left to close and the sixth solenoid valve 35 on the left to open, and then driving the turntable 13 to rotate a quarter of a turn and then stop. In this process, the driven shaft 26 is driven to rotate through the meshing effect between the second gear 28 and the ring gear 19, and the reciprocating screw 27 rotates accordingly. In this process, the lifting block 29 is driven to move down from the top of the reciprocating screw 27 to its bottom end, thereby driving the pusher block 31 through the lifting rod 30. The material block 31 moves downward, thereby driving the piston 24 on the left to move downward, and injecting the anesthetic waste gas inside the left control cylinder 18 into the gas injection pipe 6 again through the second return pipe 33 on the left, and injecting it into the solution again through the shunt pipes 41, so as to perform secondary purification on the anesthetic waste gas. At this time, the fifth solenoid valve 34 on the right is in an open state, so that the anesthetic waste gas re-injected into the solution enters the right control cylinder 18 through the first return pipe 32 on the right, thereby driving the piston 24 on the right to move upward, and the spring 25 is compressed accordingly. As the turntable 13 continues to rotate a quarter of a turn, the reciprocating screw 27 continues to rotate, and the lifting block 29 moves from the bottom end of the reciprocating screw 27 to its top end. In this process, the pushing block 31 is driven The fifth solenoid valve 34 on the right and the sixth solenoid valve 35 on the left are in the closed state, and the sixth solenoid valve 35 on the right and the fifth solenoid valve 34 on the left are in the open state. Thus, when the pusher block 31 is driven to move upward and does not limit the top of the left piston 24, the right piston 24 is driven to move downward by the rebound force of the spring 25, and the anesthetic waste gas inside the right control cylinder 18 is injected into the gas injection pipe 6 again through the second reflux pipe 33, and is injected into the solution again through the shunt pipes 41, and the anesthetic waste gas is purified three times, and the anesthetic waste gas injected into the solution is re-injected into the left control cylinder 18 through the first reflux pipe 32 on the left, and the left piston 24 is driven to move upward again, and the above operation is repeated.When the turntable 13 is driven to rotate a quarter of a turn, after the anesthetic waste gas is purified four times, the third solenoid valve 21 is controlled to open, and the anesthetic waste gas fully treated in the processing tank 5 is discharged to the inside of the box 1 through the air guide pipe 20, and finally discharged through the exhaust pipe 3 and the filter 4.
