DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0041] Example:

[0042] like Figures 1 to 10As shown, an anesthetic gas purification device for clinical anesthesia includes a bracket 1, a first purification device 2 is fixedly connected to the upper end of the bracket 1, a second purification device 3 connected to the first purification device 2 is provided inside the first purification device 2, and a heat dissipation channel is formed between the first purification device 2 and the second purification device 3; the first purification device 2 is used to condense water vapor in the air so that water-soluble anesthetic components are collected along with the water vapor, and the second purification device 3 adsorbs the anesthetic gas not collected by the first purification device 2 through activated carbon.

[0043] To ensure the collection efficiency of the first purification device 2, the first purification device 2 utilizes an annular pipeline 22 formed by coaxially connecting two sleeves 21. This maximizes the air's contact time within the first purification device 2 while maintaining a relatively small volume. Both ends of the annular pipeline 22 are sealed. The outer sleeve 21 is provided with a first air inlet 23, and the inner sleeve 21 is provided with a first exhaust port 24, which is equipped with a one-way valve 25. A draft eliminator 5 is connected to one end of the first purification device 2. Air is extracted from the first exhaust port 24 by the draft eliminator 5, allowing air to continuously enter the first purification device 2 from the first air inlet 23.

[0044] A water collecting tank 4 is provided at the lower end of the first purification device 2 and is sealed and connected to the annular pipeline 22. Condensate water diversion grooves 212 that cooperate with the water collecting tank 4 are provided on both sides of the annular pipeline 22. The condensation plate 211 is inclined toward the condensation water diversion groove 212 on the corresponding side, so that the condensed water enters the water collecting tank 4 through the condensation water diversion groove 212 for collection.

[0045] A plurality of slots 26 are circumferentially arranged on the inner side of the first purification device 2 , and semiconductor cooling fins 27 are arranged in the slots 26 . The cold end of the semiconductor cooling fin 27 is bonded to the inner sleeve 21 through a heat-conducting material, which can better cool the first purification device 2 . The hot end of the semiconductor cooling fin 27 extends out of the slots 26 and is connected to a heat sink 28 .

[0046] Preferably, the middle portion of the annular pipeline 22 is divided into a left cooling channel 29 and a right cooling channel 210 by a partition. The left cooling channel 29 and the right cooling channel 210 are each connected to the first air inlet 23 via an on-off valve. The left cooling channel 29 and the right cooling channel 210 each correspond to an independent semiconductor cooling plate 27. This allows the left cooling channel 29 and the right cooling channel 210 to operate alternately, preventing the semiconductor cooling plate 27 from malfunctioning due to prolonged operation. Condensation plates 211 are alternately arranged in the left cooling channel 29 and the right cooling channel 210. The condensation plates 211 are connected to the outer surface of the inner sleeve 21. The semiconductor cooling plates 27 maintain a low temperature for the condensation plates 211, facilitating the liquefaction of water vapor.

[0047] The second purification device 3 includes a mounting frame 31 and an adsorption chamber 32 disposed on the mounting frame 31. The adsorption chamber 32 is provided with a second air inlet 33 and a second air outlet 34. An activated carbon plate 35 is provided in the passage between the second air inlet 33 and the second air outlet 34. The activated carbon adsorbs anesthetic gases in the air.

[0048] To facilitate installation and replacement of activated carbon, adsorption chamber 32 includes an adsorption rack 36 and an activated carbon plate rack 37 movably inserted into adsorption rack 36. A socket is provided in the middle of activated carbon plate rack 37 for inserting activated carbon plate 35. Multiple air holes 38 are provided at the top and bottom of activated carbon plate rack 37. Air enters activated carbon plate rack 37 through air holes 38, is filtered and adsorbed by activated carbon plate 35, and then is discharged.

[0049] To prevent anesthetic gas from escaping from the old activated carbon plate 35 when the activated carbon is replaced, offset plates 310 are installed at the top and bottom of the activated carbon plate frame 37. These offset plates 310 are provided with offset holes 311 that are staggered with the air holes 38. When there is a gap between the offset plates 310 and the activated carbon plate frame 37, air can enter the activated carbon plate 35 through the air holes 38 and the offset holes 311. When the offset plates 310 and the activated carbon plate frame 37 are in contact, the air holes 38 and the offset holes 311 are blocked, preventing gas from escaping.

[0050] To facilitate control of the position of the offset plates 310, parallelogram linkage structures 39 are hinged at both ends of the activated carbon plate frame 37. The ends of the two parallelogram linkage structures 39, facing away from the activated carbon plate frame 37, are slidably connected to the offset plates 310. The adsorption frame 36 is provided with guide grooves 312 for vertically guiding the offset plates 310. When the parallelogram linkage structures 39 rotate, they push the offset plates 310 upward or downward, thereby moving them away from or closer to the activated carbon plate frame 37.

[0051] The parallelogram linkage structure 39 is connected to the control structure 6, which includes a first link 61 and a second link 62 hinged at one end. The other end of the first link 61 is hinged to the parallelogram linkage structure 39. The adsorption frame 36 is provided with a horizontal slot 63, and the second link 62 is slidably inserted into the horizontal slot 63.

[0052] When the activated carbon plate rack 37 needs to be disassembled, the second connecting rod 62 is pulled outward, so that the parallelogram connecting rod structure 39 drives the offset plate 310 to fit the activated carbon plate rack 37 to seal the activated carbon plates 35 in the activated carbon plate rack 37 .

[0053] When the activated carbon plate rack 37 needs to be installed, the offset plate 310 is first placed against the activated carbon plate rack 37 to facilitate its overall insertion into the adsorption rack 36. Then, the second connecting rod 62 is pushed inward to allow the offset plate 310 to separate from the activated carbon plate rack 37, facilitating its operation. A limiting structure 64 is provided between the second connecting rod 62 and the activated carbon plate rack 37. Preferably, the limiting structure 64 includes a rod that is slidably inserted into the activated carbon plate rack 37. The second connecting rod 62 is provided with a socket 65 that cooperates with the rod. When the second connecting rod 62 is fully inserted, the rod is inserted into the socket 65 to lock the position of the second connecting rod 62.

[0054] A sealing cover 313 is provided at one end of the adsorption frame 36 , and the sealing cover 313 cooperates with the offset plate 310 and the activated carbon plate frame 37 in a sealing manner to ensure that the gas passes through the activated carbon plate frame 37 .

[0055] A sealing rubber sheet 314 is provided on one side of the offset plate 310 close to the activated carbon plate frame 37 . The sealing rubber sheet 314 is provided with an opening corresponding to the offset plate 310 , and the sealing rubber sheet 314 ensures sealing.

[0056] The induced draft fan 5 includes a closed sleeve 55 and a driving mechanism arranged in the closed sleeve 55. The closed sleeve 55 is fixedly connected to the first purification device 2. The driving mechanism includes a telescopic frame 56 and a guide wheel frame 57 that are rotatably connected. The middle part of the telescopic frame 56 is fixedly connected to the closed sleeve 55. A rotary drive 58 is provided between the guide wheel frame 57 and the telescopic frame 56, and the guide wheel frame 57 is driven to rotate by the rotary drive 58.

[0057] First guide rollers 59 are rotatably provided on both sides of the telescopic frame 56 , and a spring 510 is provided between the two first guide rollers 59 , so that the two first guide rollers 59 tend to move away from each other through the spring 510 .

[0058] A second guide roller 511 is provided at each end of the guide roller frame 57. Preferably, the second guide roller 511 is rotatably connected to the guide roller frame 57. The outer sides of the first guide roller 59 and the second guide roller 511 are covered with an annular rubber sleeve 512. The ends of the rubber sleeve 512 are sealed with a ductile rubber material 513. A first variable volume cavity 51 is formed between the sealing sleeve 55 and the rubber sleeve 512, and a second variable volume cavity 52 is formed inside the rubber sleeve 512.

[0059] Preferably, to reduce the impact of deformation of the rubber material 513 on the volumetric efficiency of the rubber sleeve 512, the outer side of the rubber material 513 contacts the sidewall of the closed sleeve 55, and the inner side of the rubber material 513 is supported by multiple support rods. To adapt to the shape changes of the two ends of the rubber sleeve 512, the support rods are adaptive telescopic rods.

[0060] When the guide wheel frame 57 rotates, the second guide roller 511 applies force to the rubber sleeve 512, causing the volume of the first variable volume chamber 52 to continuously change; at the same time, the volume of the first variable volume chamber 51 changes with the volume of the first variable volume chamber 52.

[0061] Both the first variable volume chamber 51 and the second variable volume chamber 52 are provided with an air inlet 53 and an air outlet 54. Both the air inlet 53 and the air outlet 54 are one-way flow ports, which can be achieved by installing a one-way valve. The air inlet 53 of the first variable volume chamber 5 can be arbitrarily positioned. The air outlet 54 of the first variable volume chamber 5 is located at one end of the heat dissipation channel, facilitating heat dissipation from the heat sink 28 of the semiconductor cooling plate 27. The air inlet of the second variable volume chamber 52 is connected to the first exhaust port 24, and the air outlet 54 of the second variable volume chamber 52 is connected to the second purification device 3, thereby connecting the first purification device 2 and the second purification device 3 and driving air flow.

[0062] The above only describes in detail the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
