A method of using a monitoring device, comprising: the motor (5) is powered on, the motor (5) can drive the rotating shaft (6) to rotate, the rotating shaft (6) drives the base (7) and the gas cylinder (8) to rotate together, and the upper end of the gas cylinder (8) can rotate in the circular ring (12) when the gas cylinder (8) rotates due to the fact that the circular ring (12) is rotatably connected with the upper end of the gas cylinder (8), so that the gas cylinder (8) can rotate more stably;
the air pump (13) above the cover plate (22) is powered on, the air pump (13) can pump external air into the air pipe (14), and the air can be conveyed into the air bottle (8) through the air pipe (14).
8. A method of using a monitoring device according to claim 7, wherein: because the air pipe (14) is positioned above the filter screen (10), air exhausted from the air pipe (14) can slowly pass through the filter screen (10), the filter screen (10) can filter dust in the air, the air can be slowly diffused to the lower part inside the air bottle (8) along with gradual exhausting of the air into the air bottle (8), the process can pass through the drying screen plate (11), a drying agent is arranged in the drying screen plate (11), and the drying agent can absorb moisture in the air and dry the air.
