The air inlet shell 11 can be extended indefinitely as needed, and the air supply fan 12 has a built-in drive motor, which is a prior art and is not explained here.

[0026] See also Figure 3The water delivery pipe 13 includes a water delivery pipe 131, which can be extended indefinitely as needed. The water delivery pipe 131 is fixedly connected to the upper part of the air inlet housing 11, and a plurality of water storage pipes 132 are evenly and fixedly connected to the bottom side of the water delivery pipe 131. A one-way valve is connected between the water storage pipe 132 and the water delivery pipe 131. Water can be delivered to each water storage pipe 132 through the water delivery pipe 131. The one-way valve prevents water from flowing back. When the water storage pipe 132 is full, it will flow to the next water storage pipe 132. The end of the water storage pipe 132 away from the water delivery pipe 131 is fixedly connected to a pressure pipe 133, and the side of the pressure pipe 133 close to the air supply fan 12 is fixedly connected to an atomizing nozzle 135.

The rotating column 242 can ensure that the air monitoring needle 243 is always vertically downward under gravity, and will not move and rotate with the transport chain 22 during transportation.

[0033] The air monitoring needle 243 detects the air through the built-in battery to drive the internal components and transmits the data to the terminal through signals. This is existing technology and will not be explained here.
