[0013] By adopting the above technical solution, air enters the air inlet chamber and the first positioning plate through the air inlet hole.

[0014] As a further embodiment of this utility model: the side of the second sealing plate is provided with an annular groove, and the side of the second positioning plate facing the second sealing plate is integrally connected with an annular plate that is inserted into the annular groove.

[0015] By adopting the above technical solution, the ring plate of the second positioning plate will be inserted into the annular groove, increasing the stability of the second sealing plate.

[0016] Preferably, the air outlet is provided with multiple outlets.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Move the second positioning plate toward the first positioning plate until the two are engaged. The engagement process is that the first protrusion on the second positioning plate engages into the first slot, and at the same time the locking block engages into the second slot, thus achieving engagement. The blower blows towards the air outlet, and a negative pressure is formed at the back of the blower, thus forming a circulation.
