DETAILED DESCRIPTION

[0020] 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.

[0022] In order to ensure the collection effect of the first purification device 2, the first purification device 2 adopts an annular pipeline 22 formed by coaxially connecting two sleeves 21, and the contact time of air in the first purification device 2 is prolonged as much as possible under the premise of maintaining a small volume. Both ends of the annular pipeline 22 are closed, and a first air inlet 23 is provided on the sleeve 21 located outside, and a first exhaust port 24 is provided on the sleeve 21 located inside. The first exhaust port 24 is provided with a one-way valve 25. One end of the first purification device 2 is connected to the air inducer 5, and air is extracted from the first exhaust port 24 through the air inducer 5, so that air can continuously enter the first purification device 2 from the first air inlet 23.

[0023] A water collecting tank 4 sealed and connected to the annular pipeline 22 is provided at the lower end of the first purification device 2. Condensate water diversion grooves 212 cooperating with the water collecting tank 4 are provided on both sides of the annular pipeline 22. The condensation plate 211 is inclined toward the condensate water diversion groove 212 on the corresponding side, so that the condensed water enters the water collecting tank 4 through the condensate water diversion groove 212 for collection.

[0024] A plurality of slots 26 are circumferentially arranged on the inner side of the first purification device 2, and semiconductor cooling sheets 27 are arranged in the slots 26. The cold ends of the semiconductor cooling sheets 27 are bonded to the inner sleeve 21 through heat-conductive materials, so as to better cool the first purification device 2. The hot ends of the semiconductor cooling sheets 27 extend out of the slots 26 and are connected to heat sinks 28.

[0025] Preferably, the middle part of the annular pipeline 22 is divided into a left cooling channel 29 and a right cooling channel 210 by a partition, and the left cooling channel 29 and the right cooling channel 210 are respectively connected to the first air inlet 23 through a switch valve, and the left cooling channel 29 and the right cooling channel 210 correspond to independent semiconductor cooling sheets 27. The left cooling channel 29 and the right cooling channel 210 can work alternately to avoid the semiconductor cooling sheet 27 from malfunctioning due to long-term operation.

The condensation plates 211 are kept at a relatively low temperature through the semiconductor cooling sheets 27, so as to facilitate the liquefaction of water vapor.

[0026] 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 disposed on the passage between the second air inlet 33 and the second air outlet 34. The activated carbon is used to adsorb the anesthetic gas in the air.

[0027] In order to facilitate the installation and replacement of activated carbon, the adsorption chamber 32 includes an adsorption frame 36 and an activated carbon plate frame 37 movably inserted in the adsorption frame 36. A socket for inserting the activated carbon plate 35 is provided in the middle of the activated carbon plate frame 37. A plurality of air holes 38 are provided at both the upper and lower ends of the activated carbon plate frame 37. Air enters the activated carbon plate frame 37 through the air holes 38, and is discharged after being filtered and adsorbed by the activated carbon plate 35.

When there is a gap between the offset plates 310 and the activated carbon board frame 37, air can enter the activated carbon board 35 through the air holes 38 and the offset holes 311. When the offset plates 310 and the activated carbon board frame 37 are attached, the air holes 38 and the offset holes 311 are blocked, so that the gas in the activated carbon board 35 cannot escape.

[0029] In order to facilitate the control of the position of the offset plate 310, parallelogram connecting rod structures 39 are hinged at both ends of the activated carbon plate frame 37, and the ends of the two parallelogram connecting rod structures 39 away from the activated carbon plate frame 37 are slidably connected to the offset plate 310, and the adsorption frame 36 is provided with a guide groove 312 for vertically guiding the offset plate 310. When the parallelogram connecting rod structure 39 rotates, the parallelogram connecting rod structure 39 pushes the offset plate 310 to move upward or downward, thereby moving away from or close to the activated carbon plate frame 37.

[0030] 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, and a horizontal slot 63 is provided on the adsorption frame 36, and the second link 62 is slidably inserted in the horizontal slot 63; When the activated carbon plate frame 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 frame 37 to seal the activated carbon plate 35 in the activated carbon plate frame 37 .

[0031] When the activated carbon plate rack 37 needs to be installed, the offset plate 310 is first fitted to the activated carbon plate rack 37 to facilitate its overall insertion into the adsorption rack 36, and then the second connecting rod 62 is pushed inward to make the offset plate 310 leave the activated carbon plate rack 37 to facilitate 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 plug rod slidably inserted on the activated carbon plate rack 37, and a socket 65 cooperating with the plug rod is provided on the second connecting rod 62. When the second connecting rod 62 is fully inserted, the position of the second connecting rod 62 is locked by inserting the plug rod into the socket 65.

[0032] 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 .

[0033] 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 performance is ensured by the sealing rubber sheet 314 .

[0034] The induced draft device 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 arranged 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.

[0035] 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 .

[0036] The guide wheel frame 57 is provided with a second guide roller 511 at both ends, and preferably, the second guide roller 511 is rotatably connected to the guide wheel 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, and both ends of the rubber sleeve 512 are closed by a ductile rubber material 513, a first variable volume cavity 51 is formed between the closed sleeve 55 and the rubber sleeve 512, and a second variable volume cavity 52 is formed inside the rubber sleeve 512.

[0037] Preferably, in order to reduce the influence of deformation of rubber material 513 on the volumetric efficiency of rubber sleeve 512, the outer side of rubber material 513 contacts the side wall of closed sleeve 55, and the inner side of rubber material 513 is supported by multiple support rods. In order to adapt to the shape change of both ends of rubber sleeve 512, the support rods are adaptive telescopic rods.

[0038] When the guide wheel frame 57 rotates, the second guide roller 511 applies force to the rubber sleeve 512, so that the volume of the first variable volume chamber 52 changes continuously; at the same time, the volume of the first variable volume chamber 51 changes with the volume of the first variable volume chamber 52.

[0039] The first variable volume chamber 51 and the second variable volume chamber 52 are both provided with an air inlet 53 and an air outlet 54, and the air inlet 53 and the air outlet 54 are both one-way flow ports, and the one-way flow port can be realized by setting a one-way valve. The air inlet 53 of the first variable volume chamber 5 can be set arbitrarily, and the air outlet 54 of the first variable volume chamber 5 is located at one end of the heat dissipation channel, which is convenient for heat dissipation of the heat sink 28 of the semiconductor refrigeration 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, which is used to connect the first purification device 2 and the second purification device 3 and drive air flow.

[0040] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
