The guide vane 600 is located in the air duct 510, and the opposite sides of the guide vane 600 are connected to the housing 500 and the motor respectively. The base 100 and the guide vanes 600 are used to guide the airflow entering the air duct 510 so that the airflow is blown out along the axial direction of the motor base 100 .

It should be noted that the casing 500 is provided with a stator 700 and a rotating shaft 800 . The stator 700 is ring-mounted outside the rotating shaft 800 . The end of the rotating shaft 800 can be connected to an impeller. The impeller rotates following the rotating shaft 800 and generates airflow. The airflow passes through the air inlet 520 . Entering the air duct 510, the air is discharged from the air outlet 530 through the guide vane 600. The vibration generated when the rotating shaft 800 rotates and the vibration generated by the air flow in the air duct 510 can be transmitted outward through the motor base 100; through the motor base 100 The first damping member 300 and the second damping member 400 are arranged at intervals between the mounting cover 200 and the mounting cover 200 to reduce vibration transmission from the motor base 100 to the mounting cover 200 .

When the motor is working, high-speed airflow will be generated in the air duct 510. Since the air duct 510 is located around the outside of the casing 500, driven by the high-speed air flow, the area of the casing 500 facing away from the air duct 510 is prone to generate a negative pressure area. There is turbulence in the negative pressure area, which affects the air at outlet 530. Based on this, by setting the first air guide part 420 in a flared shape, the first air guide part 420 guides the diffusion of the air flow discharged from the air outlet 530 to facilitate the air outlet and keep the air flow away from the casing 500 The central area can reduce the negative pressure area and the impact of the negative pressure area on the air flow.

Furthermore, the first air guide part 420 is in contact with the end surface of the motor base 100, and the inner edges of the two joints overlap, so that the inner wall of the motor base 100 and the inner wall of the first air guide part 420 smoothly transition, so that the air outlet from the air outlet The airflow blown out by 530 is directly guided by the first air guide part 420 and diffused, thereby reducing the collision of the airflow with the first air guide part 420 when transitioning to the first air guide part 420 and reducing noise.

It should be noted that the first air guide portion 420 is in contact with the end surface of the motor base 100 in the direction toward the air inlet 520 , and the end surface of the second shock absorber 400 is in contact with the limiting protrusion in the direction toward the air inlet 520 . At step 230, the second shock absorbing member 400 is stably installed between the motor base 100 and the mounting cover 200, and provides a flow guiding effect.

Inclined toward the motor base 100 , the second air guide part 540 is in a flared shape, and the wall thickness of the second air guide part 540 gradually decreases in the direction away from the air inlet 520 , so the airflow in the air duct 510 can gradually move away from the load. The pressure zone is separated from the negative pressure zone, which can reduce the interference of the negative pressure zone to the air flow.

In one embodiment, when the second limiting portion 410 is configured in a protruding form, the second limiting portion 410 protrudes toward the motor base 100 relative to the inner wall of the second shock absorbing member 400 , and the guide vane 600 faces a side of the motor base 100 . A mounting slot 610 is provided on the side, and the second limiting portion 410 is embedded in the mounting slot 610 to limit the position of the second shock absorbing member 400 . It should be noted that the first limiting part 110 is configured as a hole that penetrates the motor base 100 in the radial direction, and the hole is connected with the mounting groove 610. The second limiting part 410 is inserted into the mounting hole and the mounting groove 610 at the same time, so as to The second shock absorbing component 400 is fixed between the mounting cover 200 and the motor base 100 .

In this embodiment, the second limiting part 410 is inserted into the first limiting part 110 and the guide vane 600 at the same time, which increases the insertion depth of the second limiting part 410 and improves the limiting strength of the second limiting part 410. high; and the thickness of the guide vane 600 in the circumferential direction of the motor base 100 is utilized so that the guide vane 600 cooperates with the motor base 100 to limit the position of the second shock absorbing member 400 .

Slots for installation of guide vanes 600. In addition, the thickness of the guide vane 600 in the circumferential direction gradually increases along the direction extending from the air inlet 520 to the air outlet 530. On the one hand, the guide vane 600 has sufficient thickness to provide the mounting groove 610 for the second limiting portion 410 to be inserted. On the other hand, since the leeward side of the guide vane 600 will generate a negative pressure area and interfere with the air flow, by increasing the thickness of the guide vane 600, the inclination of the leeward side of the guide vane 600 is reduced, which is beneficial to reducing the negative pressure area and Effect of negative pressure zone on airflow.
