[0075] In this embodiment, the included angles between the first hundred blades 1532 and the second hundred blades 1533 and the first direction are both α, where the value range of α is 40° ≤ α ≤ 60°. It can be understood that the value range of α can be any one of 40° ≤ α ≤ 60°, 45° ≤ α ≤ 60°, 50° ≤ α ≤ 60°, and 55° ≤ α ≤ 60°.

[0076] It should be noted that by controlling the included angles between the first hundred blades 1532 and the second hundred blades 1533 and the first direction, the first hundred blades 1532 and the second hundred blades 1533 provide a guiding effect on the gas flowing through the air inlet, so that the gas can flow through the first hundred blades 1532 and the second hundred blades 1533 in the direction of the air inlet end of the fan 200, ensuring the stability of the gas flow rate flowing through the air inlet end of the fan 200.
