The through pipe 15 is connected to the compressed air device 14, the air pressure gauge 13, the adjusting valve 12, and the conveyor 11, thereby allowing the fresh air delivered by the compressed air device 14 to be delivered to the conveyor 11 through the through pipe 15. The conveyor 11 is actually a pump body. When fresh air enters the inside of the conveyor 11, the conveyor 11 can provide power to deliver fresh air to the inside of the connecting pipe 10, and then to the inside of the connecting hose 8, and finally to the inside of the sealed helmet 3 through the connecting hose 8, for the staff to breathe. When the compressed air device 14 delivers fresh air into the through pipe 15, the fresh air can flow through the air pressure gauge 13. The air pressure of the fresh air can be checked through the air pressure gauge 13. When the air pressure is still too high, the adjusting valve 12 can be opened to further reduce the pressure of the fresh air for the staff to use.

[0028] Referring to Figure 1 As shown, the connecting part of the connecting hose 8 and the sealing helmet 3 is provided with an air control valve 7.

[0029] Specifically, the opening size between the connecting hose 8 and the sealing helmet 3 can be adjusted through the air control valve 7, and thus the air size flowing into the sealing helmet 3 can be adjusted.

[0031] Specifically, the exhalation valve 6 is opened when the staff exhales, for discharging the air exhaled by the staff, and the helmet shunt valve 16 can prevent a large amount of compressed air from rushing into the helmet in a short time when the air control valve 7 is disabled, so as to prevent the eardrum and the weak areas such as the eyes of the staff from being damaged, and to ensure the safety during use.

[0032] Referring to Figure 3 As shown, the inner side of the tightening part 2 is provided with an inflatable rubber ring 19, the outer side of the tightening part 2 is provided with an air inlet 17, one end of the air inlet 17 is communicated with the inflatable rubber ring 19, and the outer side of the air inlet 17 is provided with a sealing valve 18.

[0033] Specifically, when the staff wears the sealing helmet 3, air can be blown into the inside of the air inlet 17, so as to fill the inflatable rubber ring 19, and when the inflatable rubber ring 19 is filled, it will further closely adhere to the skin of the staff, and thus the sealing performance of the sealing helmet 3 can be further ensured, and the air inlet 17 can be sealed through the sealing valve 18, and thus the gas in the inflatable rubber ring 19 can be prevented from running out.

[0034] Referring to Figure 3 and Figure 4 As shown, the outer side of the mounting frame 4 is provided with two moving grooves 20, the inner sides of the two moving grooves 20 are respectively provided with sliding rods 21, the two sliding rods 21 are provided with sliding blocks 23, the two sliding blocks 23 are fixedly connected with a pull plate 24, one side of the pull plate 24 is provided with a cleaning pad 25, the outer sides of the two sliding rods 21 are sleeved with telescopic springs 22, one side of the pull plate 24 is provided with two bolts 26, and one side of the pull plate 24 is fixedly connected with a pull block 27.

[0035] Specifically, in the combustion experiment, the combustion substance will generate particles with strong adhesion, which can be attached to the surface of the perspective lens 5, at this time the pull plate 24 can be pulled, and the cleaning pad 25 is moved on the surface of the perspective lens 5, in use, the glass water can be soaked on the surface of the cleaning pad 25, and when the cleaning pad 25 moves on the surface of the perspective lens 5, the adhered objects on the surface of the perspective lens 5 can be cleaned, thereby preventing the adhered objects from affecting the field of view of the worker, and increasing the convenience of the device in use. By removing the bolt 26, the cleaning pad 25 can be removed from the pull plate 24, so as to replace different cleaning pads 25 for subsequent use.

[0036] Working principle: when using the device, the worker can wear the jacket 1 and wear the sealed helmet 3, and inflate the inside of the air inlet 17 to fill the inflatable rubber ring 19, thereby ensuring the sealing of the sealed helmet 3, and closing the sealing valve 18 to prevent the air in the inflatable rubber ring 19 from escaping, when the combustion experiment is carried out, the compressed air equipment 14 can be opened, the compressed air equipment 14 can compress and store fresh air outside, and discharge to the inside of the pipe 15 through the internal pressure reducing valve, and then transmitted to the inside of the conveyor 11 through the pipe 15, the conveyor 11 provides power to transmit fresh air to the connecting pipe 10, and then transmitted to the connecting hose 8 through the connecting pipe 10, and then transmitted to the inside of the sealed helmet 3 through the connecting hose 8, so as to facilitate the worker to breathe, when small particles generated by the combustion experiment are attached to the surface of the perspective lens 5, the pull block 27 can be pulled, the pull block 27 drives the pull plate 24 to move, the pull plate 24 drives the cleaning pad 25 to move on the surface of the perspective lens 5 to wipe, so as to clean the perspective lens 5, and the pull plate 24 can be loosened by pulling once, at this time the extension spring 22 can push the sliding block 23 to reset through the reverse force, so as to push the pull plate 24 to reset, and then the cleaning pad 25 can move back and forth, the device ensures the breathing environment of the worker when in use, and also enhances the practicability when in use.
