[0053] The embodiments of the present application will be described below in conjunction with Figures 1 to 13 .

[0057] As shown in Figure 2 , in one embodiment, the air inlet 11 and the air outlet 12 are arranged in a staggered manner along the extension length direction perpendicular to the shell 1. By arranging the air inlet 11 and the air outlet 12 in a staggered manner, the powder in the sampling channel 21 can be prevented from being discharged from the air inlet 11, causing dust explosion. As a transformable implementation, the air inlet 11 and the air outlet 12 can also be arranged opposite to each other.
