In this example, the cleaning effect of the second cleaning member 82 on the fan blade 20 can be further improved by increasing the number of the second water jet holes 820.

Further, the second cleaning member 82 can be detached from the second arm 53, so that the second cleaning member 82 can be replaced in time when damaged. In addition, in some cases, the second cleaning member 82 can be detached from the second arm 53, and water is directly sprayed to the second side of the fan blade 20 through the second water spraying hole 820, so that the second side of the fan blade 20 can be cleaned.

In order to achieve the technical effect that the second cleaning member 82 can be detached from the second arm 53, the present invention further provides the following technical solutions: as shown in fig. 3, one side of the second cleaning member 82 has a third burring 821.

Further, as shown in fig. 2, the positioning member 61 may have a block shape, and the outer dimension thereof is gradually reduced in a direction away from the rotating member 6. Preferably, the positioning member 61 is tapered in shape. Therefore, when the positioning piece 61 is gradually inserted into the interval between two adjacent fan blades 20, the positioning piece 61 can conveniently position the fan blades 20.
