Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 7 , the present utility model provides a technical solution: a handheld carbon monoxide monitoring device, including a protective shell 1 and a folding component 2. The folding component 2 is arranged at the bottom of the protective shell 1. The folding component 2 includes a fixing plate 201, and the fixing plate 201 is fixedly connected to the bottom of the protective shell 1. A rotating shaft 202 is fixedly connected to the middle of the fixing plate 201. A connecting block 203 is rotatably connected to the outside of the rotating shaft 202. An engaging block 204 is fixedly connected to the top of the connecting block 203. An engaging groove 205 is opened at the bottom of the protective shell 1. A binding frame 206 is arranged on one side of the fixing plate 201. A limiting component 3 is arranged on one side of the connecting block 203.

[0024] In this embodiment, as Figure 1 , Figure 3 and Figure 5 shown, the limiting component 3 includes a first limiting hole 301 which is opened on one side of the connecting block 203. A limiting block 302 is movably connected to the inner cavity of the first limiting hole 301. A limiting spring 303 is fixedly connected to the other side of the limiting block 302. A second limiting hole 304 is opened on one side of the connecting block 203. A first handle 305 is fixedly connected to the other side of the limiting spring 303. A protection component 4 is arranged on the top of the protective shell 1. Then, the staff presses the limiting block 302, and the limiting block 302 squeezes the limiting spring 303 inward. The contraction of the limiting spring 303 causes the limiting block 302 to enter the inside of the connecting block 203. At this time, the first handle 305 is pushed upward, so that the limiting block 302 pops out from the inside of the second limiting hole 304, and the first handle 305 is put away.

[0025] In this embodiment, as Figure 1 , Figure 3 and Figure 6 shown, the protection component 4 includes a connecting plate 401 which is fixedly connected to the top of the protective shell 1. Limiting grooves 402 are opened on both sides of the connecting plate 401. A limiting plate 403 is movably connected to the inner side of the limiting grooves 402. A protective cover 404 is fixedly connected to the middle of the limiting plate 403. A pull rod 405 is movably connected to the inside of the protective cover 404. A protection spring 406 is sleeved on the outside of the pull rod 405. A second handle 407 is fixedly connected to the top of the pull rod 405. A sealing cover 408 is fixedly connected to the bottom of the pull rod 405. An air intake component 5 is arranged inside the protective shell 1. When using the device, the staff uses the second handle 407 to pull the pull rod 405 in a direction away from the intake pipe 504. The pull rod 405 drives the sealing cover 408 to move away from the intake pipe 504, so that the sealing cover 408 no longer covers the intake pipe 504. Then, the pull rod 405 is slid to one side. While the pull rod 405 is sliding, the limiting plate 403 is controlled to be pulled out from the inside of the limiting grooves 402, and the protective cover 404 is removed, so that the intake pipe 504 is completely exposed.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7As shown in the figure, the intake assembly 5 includes an air storage chamber 501. The air storage chamber 501 is arranged inside the protective housing 1. A connecting pipe 502 is fixedly communicated with the top of the air storage chamber 501. A suction pump 503 is fixedly communicated with the top of the connecting pipe 502. An intake pipe 504 is fixedly communicated with the top of the suction pump 503. A filter screen 505 is fixedly connected inside the intake pipe 504. L-shaped plates 506 are fixedly connected to both sides of the intake pipe 504. A leakage prevention assembly 6 is arranged inside the air storage chamber 501. Further, the staff uses the L-shaped plates 506 to stretch the intake pipe 504. And the intake pipe 504 is a PVC telescopic pipe. The intake pipe 504 is stretched to a certain height, and then the suction pump 503 is turned on for suction. The gas enters the inside of the intake pipe 504, and the filter screen 505 will filter the dust and impurities in the gas. The gas enters the air storage chamber 501 through the suction pump 503.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 7 shown, the leakage prevention assembly 6 includes a breathable plate 601. The breathable plate 601 is fixedly connected inside the air storage chamber 501. A mounting plate 602 is fixedly connected to the middle of the breathable plate 601. A pressing spring 603 is fixedly connected to the top of the mounting plate 602. A pressing plate 604 is fixedly connected to the top of the pressing spring 603. A blocking plate 605 is fixedly connected to the top of the pressing plate 604. A carbon monoxide sensor 7 is fixedly connected to the bottom inside the air storage chamber 501. The impact force of the gas will push the blocking plate 605, and the blocking plate 605 conducts the force downward, so that the pressing plate 604 presses the pressing spring 603. When the suction pump 503 is turned off, the pressing spring 603 drives the blocking plate 605 to reset to block the air inlet of the air storage chamber 501 and prevent gas leakage.

[0028] In this embodiment, as Figure 1 and Figure 2 shown, air outlet pipes 8 are fixedly communicated with both sides of the air storage chamber 501. A plug 9 is movably connected to the inner side of the air outlet pipes 8. A display screen 10 is fixedly connected to one side of the protective housing 1. Control buttons 11 are arranged below the display screen 10.

[0029] The usage method and advantages of the present utility model: For this handheld carbon monoxide monitoring device, during use, the working process is as follows:

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when using this device, the staff member pulls the pull rod 405 away from the intake pipe 504 using the second handle 407. The pull rod 405 drives the sealing cover 408 away from the intake pipe 504, so that the sealing cover 408 no longer covers the intake pipe 504. Then, the pull rod 405 is slid to one side. While the pull rod 405 slides, the limiting plate 403 is controlled to be withdrawn from the inside of the limiting groove 402, and the protective cover 404 is removed, so that the intake pipe 504 is completely exposed. Further, the staff member uses the L-shaped plate 506 to elongate the intake pipe 504. And the intake pipe 504 is a PVC telescopic pipe. The intake pipe 504 is elongated to a certain height, and then the suction pump 503 is turned on for suction. The gas enters the inside of the intake pipe 504, and the filter screen 505 filters the dust and impurities in the gas. The gas enters the storage chamber 501 through the suction pump 503. The impact force of the gas will push the plug plate 605, and the plug plate 605 conducts the force downward, so that the extrusion plate 604 squeezes and presses against the spring 603. When the suction pump 503 is turned off, the pressing spring 603 drives the plug plate 605 to reset to block the air inlet of the storage chamber 501 and prevent gas leakage. The carbon monoxide sensor 7 monitors the carbon monoxide concentration in the gas, and the concentration data will be displayed through the display screen 10, which is convenient for the staff to read the data. After the monitoring is completed, the staff takes the device to an open place, pulls out the plug 9 to discharge the gas from the outlet pipe 8. Immediately afterwards, the staff presses the limiting block 302, and the limiting block 302 squeezes the limiting spring 303 inward. The limiting spring 303 contracts so that the limiting block 302 enters the inside of the connecting block 203. At this time, the first handle 305 is pushed upward, so that the limiting block 302 pops out from the inside of the second limiting hole 304, and the first handle 305 is put away. Finally, the connecting block 203 is rotated on the rotating shaft 202, the engaging block 204 is moved out of the engaging groove 205, and then the connecting block 203 is rotated into the restraint frame 206, and the connecting block 203 is folded at the bottom of the protective shell 1, which is convenient for the staff to carry the device and reduces the occupied space of the device.
