The top of the upper shell 2 is penetrated with an air inlet pipe 3, the side surface is communicated with an L-shaped air outlet pipe 19, the opening of the L-shaped air outlet pipe 19 faces downwards, so that the air which is discharged out is effectively prevented from entering the sampling device through the air inlet pipe 3 again, and meanwhile, the air which flows out from the L-shaped air outlet pipe is prevented from interfering the air flow above the sampling device. The air inlet pipe 3 extends into the bottom of the upper shell 2.
The top of the air inlet pipe 3 is communicated with a cube air inlet box 4; the magic tape female face 5 is fixed on the edges of the six faces of the cube air inlet box 4, the air inlet holes 6 are formed in the six faces of the cube air inlet box 4, the wind shielding sheets 7 cover the six faces of the cube air inlet box 4, and the magic tape face 8 is fixed on the edges of the wind shielding sheets 7; an air pump is installed on the air inlet pipe 3.
Like this the utility model discloses during the use, if need all inhale the air of periphery, then all tear windshield 7 and can make the air of periphery respectively through the entering sampling device of the six faces of square inlet box 4. When air in one direction needs to be sucked, the wind-blocking sheet 7 in the corresponding direction is torn. This allows the direction of the inhaled air to be selected as desired.
A flow meter 13 is installed in the intake pipe 3 to control the amount of air sucked, and the air pump is turned off when a preset amount is reached.
The tail end of the L-shaped air outlet pipe 19 is fixed with a bell mouth 14, and a porous air homogenizing plate 15 is arranged at the bell mouth 14, so that the air at the air outlet position is prevented from flowing fast to cause great disturbance to the surrounding air.
