That is, as shown in fig. 2, the air grille 2 is in a horizontal state, in which the air grille 2 is mounted, and in a vertical state, in which the air grille 2 is opened. If the grille 2 needs to be removed for cleaning, the first connector 3 needs to be further disconnected from the housing 1.

In this embodiment, the casing 1 is made of a metal plate, so that when the second side of the air inlet grille 2 equipped with the magnetic component is close to the casing 1, the air inlet grille 2 can be attracted with the casing 1 under the action of the magnetic component, thereby realizing the fixed connection between the second side of the air inlet grille 2 and the casing 1.

Obviously, the third reinforcing rib and the fourth reinforcing rib may not be connected to the first reinforcing rib and the second reinforcing rib, and the embodiment is not limited.

With the above arrangement, the first connecting member 3 is pivotally connected to the air intake grille 2 by the first pin 311 and the second pin 312 disposed on the vertical portion 31, and the first connecting member 3 is fixedly connected to the housing 1 by the first docking structure 3211, the second docking structure 317 and the third docking structure 318 disposed on the lateral portion 32, so that the air intake grille 2 can be pivotally disposed on the housing 1 by the first connecting member 3.
