Specifically, the clamping part 240 includes a first connection hole 207 and a second connection hole 231. The separation wall 220 is provided with a first connection buckle, and the first connection hole 207 is matched and connected with the first connection buckle to realize the detachable connection between the separation member 200 and the separation wall 220. The connecting tube 210 is provided with a second connection buckle, and the second connection hole 231 is matched and connected with the second connection buckle to realize the detachable connection between the separation member 200 and the connecting tube 210. The connecting tube 210 and the separation wall 220 are both formed on the box body 100, and finally the detachable connection between the separation member 200 and the box body 100 can be formed.

The first connecting hole 207 is located at the first separating edge 221 of the separating wall 220, and correspondingly, the first connecting hole 207 is located at the first side surface 2051 of the separating member 200. The second connecting hole 231 is located near the outlet of the connecting pipe 210, and correspondingly, the second connecting hole 231 is located on the periphery of the guide member 230 on the separating member 200.
