[0045] Working principle: When the device is needed, the outlet pipe of the ventilator is plugged into the inside of the air inlet 14, and the baffle 4 is first pushed horizontally to clear the position of the air inlet 14. At this time, multiple clamping blocks 38 can clamp the air inlet pipe, and the second limit block 42 is moved closer to the rectangular frame 40 under the tension of the second tension spring 41 to adapt to pipes of different sizes and ensure the stability of the air outlet pipe;

[0046] After the patient's exhaled gas is filtered by the side filter plate 52 and the middle filter plate 59 in turn, the ventilation fan 22 is started, which can help the circulation of the gas. After the gas is adsorbed by the graphene between the side filter plate 52 and the middle filter plate 59, disinfectant is added to the inside of the U-shaped frame 17, and the gas enters the inside of the U-shaped frame 17. After being blocked by the second vertical plate 21, it is disinfected again. After the gas is heated by multiple heating tubes 32;

[0047] After the gas is sterilized at high temperature, the dustproof plate 9 can be pushed to move horizontally, and the dustproof plate 9 drives multiple No. 1 slide bars 24 to move horizontally, and the No. 1 slide bar 24 drives the first limit block 25 to move horizontally, and the first limit block 25 stretches the first tension spring 23, and the dustproof plate 9 drives the filter cartridge 26 to extend, and the gas is filtered by the filter cartridge 26 again, and finally the sterilized gas is discharged;

[0048] When the baffle plate 4 moves, the baffle plate 4 drives the push rod 46 to move horizontally, and the push rod 46 moves out from the inside of the second insertion hole 50. At this time, the third limit block 48 drives the rectangular plug block 36 to move horizontally under the elastic force of the second spring 47, and the rectangular plug block 36 drives the plug rod 51 to move horizontally, and the plug rod 51 moves out from the inside of the slot 57, so that the braking state of the outer plate 3 can be released;

[0049] At this time, the filter assembly can be pulled out as a whole, and the graphene, side filter plates 52, and middle filter plates 59 inside can be replaced. At this time, the outer plate 3 and the inner plate 56 can be pulled out, and the middle plate 54 can be pulled out through the upper inverted T-shaped groove 53. The middle plate 54 drives the middle filter plate 59 to be pulled out from the top, and at the same time, the first positioning rod 64 is moved out from the inside of the first positioning groove 63, and the second positioning rod 66 is moved out from the inside of the second positioning groove 65.

At this time, the operating block 34 is rotated, and the operating block 34 drives the screw 35 to rotate, and the screw 35 drives the circular plate 33 to move horizontally, and the circular plate 33 drives the heating tube 32 to move horizontally, and the heating tube 32 drives the second rectangular sheet 31 and the first rectangular sheet 30 to move horizontally, and the second rectangular sheet 31 moves from the inside of the rectangular shell 1 to the inside of the rectangular groove 28. At this time, the part between the second rectangular sheet 31 and the first rectangular sheet 30 is located inside the lower arc plate 5 and the upper arc plate 7. At this time, the internal air of the lower arc plate 5 and the upper arc plate 7 can be heated through the gap between the rectangular groove 28 and the connecting hole 29, and then the inhaled pipe can be properly heated. By adjusting the number of heating tubes 32, the heating temperature can be adjusted to improve the application range of the device;

[0051] When the incoming pipe is moved out, the operating lever 8 can be rotated, and the operating lever 8 drives the annular plate 39 to rotate. The annular plate 39 can adjust the position of the arc groove 44 while rotating. At this time, the round rod 45 gradually moves, and then the multiple clamping blocks 38 move away from each other. At this time, the braking state of the incoming pipe can be released, and the pipe can be pulled out. The dustproof plate 9 and the baffle 4 can block the two ends of the rectangular shell 1, so as to realize the dustproof function of the device.
