The input end of the dust concentration sensor 12 passes through the cap body 1 and is electrically connected to the PLC controller 14 in the circuit board 13. The PLC controller 14 is electrically connected to the alarm 15. The dustproof earplug 3 includes a first rotating plate 301, which is rotatably connected to the outer surface of the cap body 1. The lower end face of the first rotating plate 301 is fixedly connected to a connecting steel bar 302, and the lower end face of the connecting steel bar 302 is fixedly connected to a telescopic seat 303. A telescopic plate 304 is fixedly connected to the inside of the telescopic seat 303. The telescopic plate 304 extends out of the telescopic seat 303 and is fixedly connected to the earmuff 305.

[0036] When the staff wears the dust warning device, when pulling the telescopic plate 304 up and down, the telescopic plate 304 will drive the earmuffs 305 to rise or fall. When the earmuffs 305 fit the ears of the staff, the dustproof earplugs 3 can protect the ears from dust, thereby preventing the staff from causing damage to the ears due to dust.

[0037] Implementation Case 2

[0038] Please refer to Figure 1As shown, the dustproof mirror 4 includes a connecting member 401, which is fixedly connected to the outer surface of the brim 2, and a dustproof frame 402 is fixedly connected to the lower side of the connecting member 401. The inside of the dustproof frame 402 is fixedly connected to a lens 403, and the number of the lenses 403 is two.

[0039] When the worker wears the dust warning device, the connector 401 can protect the eyes through the lens 403 in the dustproof frame 402 to prevent the eyes from being affected by dust, thereby affecting work efficiency.

[0040] Implementation Case 3

[0041] Please refer to Figure 5-6 As shown, the vibration alarm mechanism 5 includes a servo motor 501, which is mounted on one side of a fixed plate 511, and an output end of the servo motor 501 is fixedly connected to a shaft rod 502, which passes through the fixed plate 511 and is fixedly connected to the outer surface of a second rotating plate 503, and a connecting plate 504 is abutted on the outer surface of the second rotating plate 503, and a slider 505 is fixedly connected to the inner side of the connecting plate 504, and the slider 505 is slidably connected to the inside of a slide groove 506 opened on the outer surface of the fixed plate 511, and an impact rod 507 is fixedly connected to the end face of the connecting plate 504 away from the second rotating plate 503, and the impact rod 507 is slidably connected to the inside of a through groove 510 opened in a fixed block 509, and springs 508 are also provided on the upper and lower sides of the impact rod 507, and one end of the spring 508 on both sides is fixedly connected to the outer surface of the connecting plate 504, and the other end is fixedly connected to the inner side of the fixed plate 511, and the fixed block 509 is fixedly connected to the outer surface of the fixed plate 511.

[0042] When the dust concentration sensor 12 detects that the dust concentration exceeds the standard, the set instruction is transmitted to the alarm 15 through the PLC controller 14 on the circuit board 13. The alarm will then warn the staff to move away as soon as possible through sound. However, in a noisy environment, the staff may not be able to accurately judge whether the alarm is ringing. At the same time, the PLC controller 14 will also transmit the signal to the vibration alarm mechanism 5, and the vibration alarm mechanism 5 obtains energy through the lithium battery 10. At this time, the servo motor 501 will drive the second rotating plate 503 to rotate through the shaft 502. The second rotating plate 503 resists the connecting plate 504 and slides in the slide groove 506 through the slider 505. When the connecting plate 504 moves to the right, it drives the impact rod 507 and the spring 508 to move to the right. The impact rod 507 passes through the slide groove 506 opened by the fixed block 509 and hits the cap body 1. After the collision, under the elastic force of the spring 508, the connecting plate 504 slides to the left again. Under the repeated collision, the staff is warned to move away as soon as possible.

[0043] Implementation Case 4

[0044] Please refer to Figure 1-6 As shown, the hat hoop 9 includes a fixing rod 901, and the fixing rod 901 is fixedly connected to the lower end face of the brim 2. The lower end face of the fixing rod 901 is rotatably connected to a knob 902, and the inside of the knob 902 is rotatably connected to a connecting ring strip 903, and the outer side of the connecting ring strip 903 is fixedly connected to a tightening belt 904.

[0045] After the staff has adjusted the dustproof earplugs 3 and the dustproof mirrors 4, they turn the knob 902, and the connecting ring strip 903 is rotated inside the knob 902 to shrink the connecting ring strip 903, thereby tightening the fastening belt 904. When the staff turns the knob 902 to adapt to the dust warning device, it stops turning.

[0046] Implementation Case 5

[0047] Please refer to Figure 1-6 As shown, the servo motor 501 , the fan 6 , the lighting lamp 7 , the light alarm 8 , the dust concentration sensor 12 , the circuit board 13 , the PLC controller 14 and the alarm 15 are all electrically connected to the lithium battery 10 .

[0048] Since the servo motor 501, fan 6, lighting lamp 7, light alarm 8, dust concentration sensor 12, circuit board 13, PLC controller 14 and alarm 15 are all electrically connected to the lithium battery 10, the dust warning device is light, small and practical. At the same time, when the dust concentration sensor 12 detects that the dust concentration exceeds the standard, the light alarm 8 can be controlled to flash through the PLC controller 14. The utility model has a triple warning, so it can be used in most places, which improves the safety and reliability of the utility model.

[0049] Working principle and use process of the device: When the staff wears the dust warning device, when the telescopic plate 304 is pulled up and down, the telescopic plate 304 will drive the earmuffs 305 to rise or fall. When the earmuffs 305 fit the ears of the staff, the dustproof earplugs 3 can protect the ears from dust, thereby preventing the staff from causing damage to the ears due to dust. When the staff wears the dust warning device, the connecting piece 401 can protect the eyes through the lens 403 in the dustproof frame 402 to prevent the eyes from being affected by dust, thereby affecting work efficiency. When the dust concentration sensor 12 detects When the dust concentration exceeds the standard, the set command is transmitted to the alarm 15 through the PLC controller 14 on the circuit board 13. The alarm will warn the staff to leave as soon as possible through sound. However, in a noisy environment, the staff may not be able to accurately judge whether the alarm is ringing. At the same time, the PLC controller 14 will also transmit the signal to the vibration alarm mechanism 5, and the vibration alarm mechanism 5 obtains energy through the lithium battery 10. At this time, the servo motor 501 will drive the second rotating plate 503 to rotate through the shaft 502, and the second rotating plate 503 will press against the connecting plate 504 through the slider 50 5 slides in the slide groove 506, and when the connecting plate 504 moves to the right, it drives the impact rod 507 and the spring 508 to move to the right. The impact rod 507 passes through the slide groove 506 opened by the fixing block 509 and hits the cap body 1. After the collision, the elastic force of the spring 508 makes the connecting plate 504 slide to the left again. Under the repeated collision, the staff is warned to stay away as soon as possible. After the staff adjusts the dustproof earplug 3 and the dustproof mirror 4, the knob 902 is turned. The connecting ring strip 903 is rotated inside the knob 902 to shrink the connecting ring strip 903, thereby tightening the fastening belt 904. After the operator turns the knob 902 to adapt to the dust warning device, it stops rotating. Since the servo motor 501, fan 6, lighting lamp 7, light alarm 8, dust concentration sensor 12, circuit board 13, PLC controller 14 and alarm 15 are all electrically connected to the lithium battery 10, the dust warning device is light, small and practical. At the same time, when the dust concentration sensor 12 detects that the dust concentration exceeds the standard, the light alarm 8 can also be controlled by the PLC controller 14 to flash. The utility model has a triple warning, so it can be used in most places, which improves the safety and reliability of the utility model.
