In one embodiment, as shown in fig. 1 and 6, the housing 200 is multiple, and the housings 200 are sequentially arranged along the circumferential direction of the air duct member 100. Through the assembly of a plurality of casings 200 with wind channel 100 respectively, can be convenient for casing 200 to install and remove with wind channel 100 through the mode that relative wind channel 100 is close to or keeps away from, can be better avoid wind channel 100 and the junction of other structures simultaneously, and every part all has corresponding joint structure to carry out the joint and fixes, and is difficult for the pine to take off more.

Specifically, the two housings 200 are butted to form an annular housing disposed around the air duct member 100.

The two housings 200 may have the same or different structures, for example, the first clamping portion 110 and the second clamping portion 210 have the same clamping manner as the third clamping portion 140 and the fourth clamping portion 220, but the sizes and shapes of the first clamping portion 110, the third clamping portion 140, the second clamping portion 210 and the fourth clamping portion 220 may be adjusted according to actual situations.

An embodiment discloses a fan, which comprises a matching installation structure according to any one of the embodiments.

In the fan, after the first clamping portion 110 is clamped with the second clamping portion 210, the assembly of the housing 200 and the air duct piece 100 is completed, the housing 200 can be prevented from being separated from the air duct piece 100, the first cover 300 is then connected with the air duct piece 100, the first limiting portion 310 is located on one side of the second clamping portion 210 away from the first clamping portion 110, the second clamping portion 210 can be limited by the arrangement of the first limiting portion 310 and the first clamping portion 110, when the second clamping portion 210 has a tendency of moving in a direction close to the first limiting portion 310 and separating from the first clamping portion 110, the first limiting portion 310 will abut against the second clamping portion 210, so that the second clamping portion 210 cannot be separated from the first clamping portion 110, only after the first cover 300 is detached from the air duct piece 100, the first clamping portion 110 can be separated from the second clamping portion 210, and after the air duct piece 100, the housing 200 and the first cover 300 are assembled, the assembly and fixation of the air duct piece 100 and the housing 200 can be good, is not easy to loosen.

Alternatively, the fan may be a vaned fan, bladeless fan, or other device capable of creating an airflow.
