[0034] In this embodiment, a rotating shaft 21 is rotatably mounted on the other end of the square sliding column 18, an air intake pipe 4 is arranged on the outer surface of the negative pressure filter 2 near the rotating shaft 21, a fixing plate 19 is fixedly mounted on the inner wall of the air intake pipe 4, one end of the rotating shaft 21 passes through the outer surface of the fixing plate 19 and a driving fan blade 20 is fixedly mounted thereon, a truncated cone 29 is fixedly mounted on the circumferential outer surface of the rotating shaft 21, the outer surface of the truncated cone 29 is provided with an oblique angle, a chamfer 30 matching the oblique angle is provided on the outer surface of the fixing plate 19 near the truncated cone 29, the rotating shaft 21 and the fixing plate 19 are slidably mounted, a fixing ring 27 is fixedly mounted on the circumferential outer surface of the rotating shaft 21 near the truncated cone 29, an annular groove is provided on the circumferential outer surface of the fixing ring 27, a plurality of knocking rods 28 are rotatably mounted on the inner wall of the annular groove at equal intervals, a knocking cylinder 31 is fixedly mounted on the outer surface of the fixing plate 19 near the fixing ring 27, and the end of the knocking rod 28 is against the inner wall of the knocking cylinder 31.

[0035] The cone 29 leaves the chamfer 30, and the position of the rotating shaft 21 is released from the restriction. The air flow is driven by the negative pressure filter 2, which will drive the driving blades 20 to rotate. The driving blades 20 drive the fixing ring 27 to rotate through the rotating shaft 21. The fixing ring 27 drives the knocking rod 28 to collide with the inside of the knocking cylinder 31. Through this device, the negative pressure filter 2 can knock the knocking cylinder 31 to make a sound when filtering the leaked chlorine, which is used to remind external personnel that there is a gas leakage inside the dangerous goods container body 1.

[0036] In this embodiment, a stopper 25 is fixedly installed on the outer surface of the square slide column 18 near the other end, and a tension spring 23 is sleeved on the outer surface of the square slide column 18.

Through the sliding of the piston plate 16, when the piston plate 16 and the pressure sensor When the pressure sensor 15 is pressed against the negative pressure filter 2, the pressure sensor 15 receives an electrical signal, so that the negative pressure filter 2 increases the filtering efficiency to prevent chlorine leakage; when the annular groove 1601 on the piston plate 16 slides to the position of the square slide post 18, one end of the square slide post 18 slides into the inside of the annular groove 1601 under the force of the tension spring 23, and the position of the piston plate 16 is restricted by this device to prevent the rotating hook 8 from being unlocked. At this time, the round table 29 leaves the chamfer 30, and the position of the rotating shaft 21 is released. The air flow is driven by the negative pressure filter 2, which will drive the driving blades 20 to rotate. The driving blades 20 drive the fixing ring 27 to rotate through the rotating shaft 21, and the fixing ring 27 drives the knocking rod 28 and the knocking cylinder 31. The negative pressure filter 2 can knock on the knocking cylinder 31 to make a sound when filtering the leaked chlorine, so as to remind the outside personnel that there is a gas leakage inside the dangerous goods container body 1; when the outside personnel use the detection instrument to detect the internal gas filtration of the dangerous goods container body 1, the lever 22 is manually moved to drive the square slide column 18 to reset through the guide column 26 and the guide groove 24.
