By way of arranging the guide slots on both ends of the bottom plate 6 in the length direction, the installation of the bottom housing assembly 2 on the base 1 can be guided from both ends simultaneously when the bottom housing assembly 2 is installed. The guide structure is more stable, so that it may be ensured that the bottom housing assembly 2 is installed in position more quickly and accurately.

[0038] In an exemplary embodiment, the second guide slot 5 is shorter than the first guide slot 4, so that a differentiation design of the guide slots on both ends may be achieved. A more reasonable structural design is adopted according to different structures on both ends. Existing structures on the base 1 are prevented from being intervened while the bottom housing assembly 2 is guided effectively, so that the rationality of inner structural layout is improved.

[0039] A motor seat 11 is further arranged on the second end of the bottom plate 6, and the guide plate 10 is located on a side, close to the vertical plate 7, of the motor seat 11. As the guide plate 10 is fixedly arranged on the bottom plate 6 directly rather than installed on the motor seat 11, structural installation of other parts on the motor seat 11 is not affected, and there is no need to change the structure of the motor seat 11, so that the processing cost is lowered.

[0040] An angular rack 12 and a pressing plate 13 are further separately arranged on both ends of the bottom plate 6 of the base 1. The bottom housing assembly 2 includes a fan blade 14 which is installed in a guided manner by the pressing plate 13. The pressing plate 13 is provided with a guide surface structure which can be matched with the second guide slot 5. In a position where cannot be guided by the second guide slot 5, the bottom housing assembly 2 may be further guided through the guide surface structure of the pressing plate 13, so that it is ensured that the base 1 guides the bottom housing assembly 2 on the second end, and therefore, the bottom housing assembly 2 may be ensured to be installed in position.

[0041] A thread connection hole 15 is arranged on at least one of the angular rack 12 and the pressing plate 13, and the bottom housing assembly 2 is fixedly connected to the thread connection hole 15.
