Under the structure, after the front panel 110 rotates to expose the volute tongue mechanism 200 in the casing 100, the front volute tongue 210 is disassembled, so that the interior of the volute tongue mechanism 200 and the cross-flow fan blade 300 can be cleaned and maintained, and the operation is simple and convenient. After cleaning, the volute tongue mechanism 200 is installed, the front panel 110 rotates to the closed position, and is fixed to the front volute tongue 210 by the first fastening structure 130, so as to position the front panel 110. When an external force is applied to rotate the front panel 110 away from the closed position, the first snap structure 130 may be forcibly disengaged. Therefore, the front panel 110 of the embodiment of the present application can be conveniently opened or closed, and the volute tongue mechanism 200 and the cross-flow fan blade 300 can be efficiently cleaned and maintained by combining the detachable connection mode of the front volute tongue 210 and the rear volute tongue 220.

Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present disclosure, and it is intended that the scope of the present disclosure be defined by the appended claims.
