Thus, not only the structure of the air intake grille 12 and the constricted portion 1111 can be simplified, but also the reliability of the connection between the air intake grille 12 and the constricted portion 1111 can be increased. For example, in the example shown in fig. 21, four grille fastening slots 1113 are uniformly spaced along the circumferential direction of the necking portion 1111, four grille fastening protrusions 1211 are uniformly spaced along the circumferential direction of the air inlet inner ring 121 of the air inlet grille 12, and the four grille fastening slots 1113 and the four grille fastening protrusions 1211 are in one-to-one correspondence and are mutually matched.
