In addition, the maximum width of the first wind blocking structure 51 and the second wind blocking structure 52 can be substantially the same as the width of the first water conveying pipeline 341 and the second water conveying pipeline 342, so as to achieve a better wind balance effect.

[0061] It can be understood that the first wind blocking structure 51 and the second wind blocking structure 52 can also surround the air outlet fence 242 on both sides to form the air outlet hole 2420.

[0062] Further, the fan housing 21 can further include a decorative cover 27 connected to the side of the air outlet cover 24 away from the fan blade assembly 22. The decorative cover 27 can be a decorative ring, and the decorative ring and the air outlet cover 24 can be connected through the fixing hole and the fixing column.

[0063] It can be understood that in the embodiment, the decorative cover 36 can be a metal material, and the outer surface of the decorative cover 36 can form a plurality of convex ribs 360 arranged around the outer surface of the decorative cover 36, for improving the water accumulation phenomenon of the spray S on the outer surface of the decorative cover 36 and improving the product reliability.

[0064] Further, in the embodiment, the air outlet side of the fan blade assembly 22 is sequentially provided with an inner cover 25 and an air outlet cover 24. The air outlet cover 24 has an air outlet fence 242 connected between an air outlet part 241 and an outer frame 243, and the inner cover 25 includes an inner frame 253 corresponding to the outer frame 243, a plurality of inner fences 252 corresponding to the plurality of air outlet fences 242, and an inner plate part 251 corresponding to the air outlet part 241. The plurality of inner fences 252 are connected between the inner plate part 251 and the inner frame 253.

[0067] The plurality of inner louvers 252 are substantially uniformly distributed along the circumferential direction of the inner cover body 25, and each inner louver 252 deviates from the radial direction R2 (the radial direction R2 is the same as the extension direction R1) of the center of the annular structure of the inner cover body 25, that is, the straight line where the extension direction R3 of each inner louver 252 is located deviates from the center of the annular structure of the inner cover body 25, so as to be different from the extension direction R1 of each corresponding air outlet louver 242. In other words, the extension direction R3 of each inner louver 252 is different from the extension direction R1 of each corresponding air outlet louver 242, and the outer end (the end away from the center of the annular structure) of the extension direction R3 of each inner louver 252 deviates from the extension direction R1 toward the rotating direction R4 of the fan blade assembly 22.

[0068] The extension direction R3 of each inner louver 252 is different from the extension direction R1 of each corresponding air outlet louver 242, so that the inner cover body 25 and the air outlet cover 24 form two air gathering structures in sequence with respect to the fan blade assembly 22, that is, the plurality of inner louvers 252 and the plurality of air outlet louvers 24 sequentially compress the air outlet airflow of the fan blade assembly 22, so that the compressed air outlet airflow is more gathered and concentrated to blow out, effectively increasing the air outlet wind power to bring a more cooling experience to the user.

[0069] In particular, the outer end (the end away from the center of the annular structure) of the extension direction R3 of each inner louver 252 deviates from the extension direction R1 toward the rotating direction R4 of the fan blade assembly 22, which can further improve the compression effect of the air outlet airflow, thereby increasing the air outlet wind power.
