Therefore, the first air duct 140 is located on the air inlet side of the motor, and the second air duct 240 is located on the outlet side of the motor. On the wind side, the airflow generated by the rotation of the impeller 600 first enters the first air duct 140 from the end of the casing 100 facing away from the air outlet hood 200 , and the airflow is guided by the guide vanes 130 It enters the second air duct 240 from the first air duct 140 and then is discharged. As shown in Figure 3, the guide vanes 130 close to the air inlet side are curved, and the guide vanes 130 close to the air outlet side are straight, so that the air flow generated by the wind wheel is blown out in the axial direction through the guidance of the guide vanes 130; usually, There is an air pressure area on the leeward side of the guide vane 130 close to the air outlet side. The air flow spirals in the air pressure area and generates turbulence, which affects the axial direction of the air flow and the wind pressure. Based on this, in this embodiment, the guide vane 130 faces away from the air pressure area. The thickness of one end of the air outlet hood 200 in the circumferential direction of the casing 100 is smaller than the thickness of the end of the guide vane 130 close to the air outlet hood 200 in the circumferential direction of the casing 100. Since the thickness of the air outlet side of the guide vane 130 becomes larger, the guide vane 130 is The curvature of the inlet side when extending toward the outlet side is reduced, and the airflow can flow smoothly along the guide vane 130, reducing or even eliminating the air pressure zone on the leeward side of the guide vane 130, thereby improving the axial direction of the airflow after it is blown out. and wind pressure.
进一步，由于导叶130的厚度在朝向引风罩200的方向上具有加大的趋势，因此导叶130与导风翅片230均具有足够的厚度设置引线槽231，引线槽231可以设置在导叶130或者导风翅片230上，并且引线槽231在出风罩200的径向上贯穿，定子300连接的引出线穿设于引线槽231内，并通过引线槽231穿出机壳100外部。由此，电机内的引出线从其侧部引出，便于出风罩200与转轴400的配合安装，引出线对电机出风侧气流的影响较小，可保证出风侧的风压与风速。图2中示出了导叶130与导风翅片230均设置引线槽231的情形。Furthermore, since the thickness of the guide vanes 130 tends to increase in the direction toward the air inducing cover 200, the guide vanes 130 and the air guide fins 230 both have sufficient thickness to provide the lead grooves 231, and the lead grooves 231 can be provided in the guide. On the blade 130 or the air guide fin 230 , and the lead slot 231 penetrates in the radial direction of the air outlet cover 200 , the lead wire connected to the stator 300 is passed through the lead slot 231 , and passes out of the casing 100 through the lead slot 231 . Therefore, the lead wire in the motor is led out from its side, which facilitates the matching installation of the air outlet cover 200 and the rotating shaft 400. The lead wire has less influence on the air flow on the wind outlet side of the motor, and the wind pressure and wind speed on the wind outlet side can be ensured. FIG. 2 shows the situation where the guide vanes 130 and the air guide fins 230 are both provided with lead grooves 231 .
需要说明的是，每一导叶130朝向出风罩200的一端与相应的导风翅片230在机壳100周向上的投影重合，从而，导叶130与导风翅片230在转轴400周向上相对的两侧侧面齐平，以减小第一风道140与第二风道240连通处的风阻，保证气流吹出后的轴向性、风压及风速。It should be noted that one end of each guide vane 130 facing the air outlet hood 200 coincides with the projection of the corresponding air guide fin 230 in the circumferential direction of the casing 100 . Therefore, the guide vanes 130 and the air guide fins 230 are aligned around the rotating shaft 400 . The upper and opposite sides are flush to reduce the wind resistance at the connection between the first air duct 140 and the second air duct 240 and ensure the axial direction, wind pressure and wind speed after the air flow is blown out.
如图2所示，机壳100还包括导向部150，导向部150连接于内壳体110背向出风罩200的一端，转轴400靠近进风侧的一端穿设于导向部150，转轴400靠近出风侧的一端穿设于出风罩200。电机还包括轴承500，转轴400与导向部150之间以及转轴400与出风罩200之间均设有轴承500，轴承500与转轴400转动连接，并对转轴400进行支撑，由于转轴400的两端均受到轴承500的支撑，转轴400的轴向性及垂直度较高，转轴400安装时不易变形；可以理解的，转轴400与导向部150之间以及转轴400与出风罩200之间均可设置多个轴承500，多个轴承500组合使用，可以提升对转轴400的支撑作用，并能对转轴400进行轴向限位。As shown in Figure 2, the casing 100 also includes a guide part 150. The guide part 150 is connected to an end of the inner shell 110 facing away from the air outlet hood 200.

The rotating shaft 400 One end close to the air outlet side is inserted into the air outlet hood 200 . The motor also includes a bearing 500, which is disposed between the rotating shaft 400 and the guide part 150 and between the rotating shaft 400 and the air outlet cover 200. The bearing 500 is rotationally connected to the rotating shaft 400 and supports the rotating shaft 400. Since the two sides of the rotating shaft 400 Both ends are supported by the bearings 500. The axial direction and verticality of the rotating shaft 400 are relatively high, and the rotating shaft 400 is not easily deformed during installation. It can be understood that there is a gap between the rotating shaft 400 and the guide part 150 and between the rotating shaft 400 and the air outlet cover 200. Multiple bearings 500 can be provided. When multiple bearings 500 are used in combination, the supporting effect of the rotating shaft 400 can be improved, and the rotating shaft 400 can be axially limited.
需要说明的是，由于本发明中引出线从出风罩200的径向上引出，出风罩200背向机壳100的一端具有较大的空间可供轴承500进行安装，使轴承500与出风罩200的装配更为便捷。It should be noted that in the present invention, since the lead wire is led out from the radial direction of the air outlet hood 200, the end of the air outlet hood 200 facing away from the casing 100 has a larger space for the bearing 500 to be installed, so that the bearing 500 is in contact with the air outlet. The assembly of the cover 200 is more convenient.

The winding 320 is installed inside the iron core 310 and is arranged around the outer circumference of the rotating shaft 400. The end of the iron core 310 close to the air inlet side is in contact with the guide part 150. The iron core 310 One end close to the air outlet side is in contact with the air outlet hood 200 so that the stator 300 is fixed in the axial direction between the guide portion 150 and the air outlet hood 200 . further Referring to Figures 4 and 5, a plurality of limiting protrusions 311 are protruding from one end of the core 310 facing away from the casing 100. The limiting protrusions 311 are arranged at intervals along the circumference of the air outlet cover 200, two of which are The limiting protrusion 311 defines a lead gap 312. When the lead slot 231 is arranged on the air guide fin 230, the lead gap 312 is connected with the lead slot 231, and the lead wire from the winding 320 is passed through the lead gap 312 and the lead slot 231.

The support protrusion 211 abuts the limiting protrusion 311 in the axial direction. There are multiple support protrusions 211 arranged along the The inner cover 210 is arranged at intervals in the circumferential direction; the gaps between adjacent support protrusions 211 are connected to the lead gaps 312, thereby increasing the threading space for the lead wires and facilitating the extraction of the lead wires.

Specifically, the impeller 600 includes an inner hub 610, an outer hub 620, a first blade 630 and a second blade 640. The inner hub 610 is connected to the rotating shaft 400 and rotates with the rotating shaft 400. The outer hub 620 is arranged around the outside of the inner hub 610.
