[0038] The limiting member is connected with the corresponding positioning hole, and the limiting member abuts against the outer wall of the shell, thereby limiting the movement of the shell in the lower box body.

[0039] like Figure 1-4 As shown, in order to facilitate dust collection, the utility model adopts the air guide cover 7 which is a hollow structure that shrinks from top to bottom;

[0040] The air guide cover has a hollow structure that tapers from top to bottom, which can facilitate dust collection.

[0041] like Figure 1-2 As shown, in order to ensure the sealing of the upper box body and the lower box body after they are covered, the utility model adopts a sealing strip 13 provided at the bottom of the upper box body 2; and a sealing groove 14 matched with the sealing strip 13 is provided at the top of the lower box body 1;

[0042] The upper box body and the lower box body are covered, and the sealing strip and the sealing groove cooperate to ensure the sealing of the box body and the lower box body.

[0043] It should also be noted that when the shell is placed on the lower box body, and the upper box body is connected to the air guide part for flipping, interference between the shell and the air guide part should be avoided to ensure smooth flipping of the upper box body.

[0044] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
