After the connector 400 is locked, the motor base 100 and the draft hood 200 are detachably connected; in another example, In one embodiment, as shown in FIG. 2 , the connector 400 is plugged into the inner wall of the first housing 110 and the inner wall of the first cover 210 . After the connector 400 is locked, the connection between the motor base 100 and the draft hood 200 is realized. Removable connection. Therefore, in the present invention, the connecting part 400 is inserted into the connecting part 230 by utilizing the thickness and mutual contact relationship between the connecting part 230 and the guide vane 130, or the wall thickness and mutual abutting relationship between the first cover 210 and the first housing 110. into the guide vane 130, or after the connector 400 is inserted into the first cover body 210 and the inner wall of the first housing 110, the motor base 100 and the draft hood 200 are detachably connected, which facilitates the later disassembly and maintenance of the motor, and the motor The connection strength between the base 100 and the draft hood 200 is high, which increases the service life of the motor.
需要说明的是，连接件400可以选择螺纹紧固件，第一罩体210与第一壳体110内或者 导叶130与连接部230内设置有安装孔231，安装孔231的孔壁设有与螺纹紧固件配合的内螺纹，锁紧螺纹紧固件，即可使引风罩200与电机座100稳固连接，引风罩200与电机座100的装配工艺简单，连接稳定性高。It should be noted that the connecting member 400 can select a threaded fastener, and the first cover 210 and the first shell 110 may be connected with each other or A mounting hole 231 is provided in the guide vane 130 and the connecting portion 230. The hole wall of the mounting hole 231 is provided with an internal thread that matches the threaded fastener. By locking the threaded fastener, the draft hood 200 can be connected to the motor base 100. Stable connection, the assembly process of the draft hood 200 and the motor base 100 is simple, and the connection stability is high.
对于连接件400插接于连接部230与导叶130内的连接方式，如图6所示，导叶130位于第一风道140内，导叶130在第二壳体120周向上的厚度沿朝向引风罩200的方向逐渐增大，并且连接部230的最小厚度不小于导叶130的最大厚度，使导叶130与连接部230的抵接的一端具有足够的厚度能够与连接件400连接，提高了导叶130的结构强度以及连接件400与连接部230、导叶130的连接强度。Regarding the connection method in which the connector 400 is inserted into the connecting part 230 and the guide vane 130, as shown in FIG. 6, the guide vane 130 is located in the first air duct 140, and the thickness of the guide vane 130 in the circumferential direction of the second housing 120 It gradually increases toward the direction of the draft hood 200 , and the minimum thickness of the connecting portion 230 is not less than the maximum thickness of the guide vane 130 , so that the end of the guide vane 130 that abuts the connecting portion 230 has sufficient thickness to be connected to the connecting piece 400 , improving the structural strength of the guide vane 130 and the connection strength between the connecting piece 400 and the connecting portion 230 and the guide vane 130 .
第一风道140背向引风罩200的一端形成进风口141，朝向引风罩200的一端形成出风口142，外部气流从进风口141进入第一风道140内，并经过导叶130的导向进入第二风道240。在一个实施例中，连接部230在引风罩200的轴向上等厚，导叶130朝向引风罩200的端面与连接部230朝向电机座100的端面重合，以减小气流从第一风道140流动至第二风道240的风阻，连接部230对气流具有轴向导流作用，能够保证气流吹出后的轴向性、风压及风速。An air inlet 141 is formed at one end of the first air duct 140 away from the draft hood 200 , and an air outlet 142 is formed at one end toward the draft hood 200 . The external airflow enters the first air duct 140 from the air inlet 141 and passes through the guide vanes 130 It is guided into the second air duct 240. In one embodiment, the connecting portion 230 is equally thick in the axial direction of the air hood 200 , and the end surface of the guide vane 130 facing the air hood 200 coincides with the end surface of the connecting portion 230 facing the motor base 100 to reduce the airflow from the first The wind resistance from the air duct 140 to the second air duct 240 and the connecting part 230 have an axial guiding effect on the air flow, which can ensure the axial directionality, wind pressure and wind speed after the air flow is blown out.
靠近进风口141的导叶130呈弯曲状，靠近出风口142的导叶130呈直线状，以使气流经过导叶130的导向沿轴向吹出；通常，导叶130靠近出风侧的背风面存在空压区，气流在空压区内螺旋并产生紊流，影响气流的轴向性及风压，基于此，本实施例中，导叶130背向靠近出风口142的一端在电机座100周向上的厚度小于导叶130靠近出风口142的一端在电机座100周向上的厚度，由于导叶130出风侧的厚度变大，导叶130由进风侧向出风侧延伸时的弯曲度减小，气流可以顺畅的沿导叶130流动，减小甚至消除了导叶130背风侧的空压区，进而提升了气流吹出后的轴向性和风压。The guide vanes 130 close to the air inlet 141 are curved, and the guide vanes 130 close to the air outlet 142 are straight, so that the airflow is blown out in the axial direction through the guidance of the guide vanes 130; usually, the guide vanes 130 are close to the leeward side of the outlet side. There is an air pressure zone, and the air flow spirals in the air pressure zone and generates turbulence, which affects the axial direction of the air flow and the wind pressure. Based on this, in this embodiment, the end of the guide vane 130 facing away from the air outlet 142 is on the motor base 100 The thickness in the circumferential direction is less than the thickness of the end of the guide vane 130 close to the air outlet 142 in the circumferential direction of the motor base 100. Since the thickness of the guide vane 130 on the air outlet side becomes larger, the guide vane 130 bends when extending from the air inlet side to the air outlet side. The degree is reduced, and the airflow can flow smoothly along the guide vane 130, reducing or even eliminating the air pressure area on the leeward side of the guide vane 130, thus improving the axial direction and wind pressure after the airflow is blown out.
导叶130与第二壳体120可拆卸连接，和/或导叶130与第一壳体110可拆卸连接，电机座100可以通过装配的方式成型，便于电机座100的维护以及导叶130、第一壳体110、第二壳体120的加工。具体的，导叶130与第一壳体110之间，以及导叶130与第二壳体120之间的连接方式可以是，第一壳体110、第二壳体120上设置凹槽，导叶130***该凹槽内，从而导叶130与第一壳体110、第二壳体120在周向上相互限位，并且无需额外增加其他结构，不影响进入第一风道140的风量。The guide vane 130 is detachably connected to the second housing 120, and/or the guide vane 130 is detachably connected to the first housing 110. The motor base 100 can be formed by assembly, which facilitates the maintenance of the motor base 100 and the guide vanes 130, Processing of the first housing 110 and the second housing 120 . Specifically, the connection method between the guide vane 130 and the first casing 110 and between the guide vane 130 and the second casing 120 can be that grooves are provided on the first casing 110 and the second casing 120, and the guide vanes 130 and the second casing 120 are connected by grooves. The blades 130 are inserted into the groove, so that the guide blades 130 and the first casing 110 and the second casing 120 circumferentially limit each other, and there is no need to add other additional structures and does not affect the air volume entering the first air duct 140 .

Close to the first cover body 210, the air inducing portion 221 is expanded. When the motor is working, there is a high-speed airflow in the second air duct 240. Since the second air duct 240 is arranged outside the second cover body 220, at high speed, Driven by the air flow, the area of the second cover body 220 facing away from the second air duct 240 is prone to generate a negative pressure area. The air flow has turbulence in the negative pressure area, which affects the wind pressure and wind speed of the air flow. Based on this, by guiding the air The air inducing portion 221 is configured in a flared shape, and the air inducing portion 221 guides the discharged airflow to diffuse to facilitate the air outlet, and the airflow is away from the central area of the second cover body 220, which can reduce the negative pressure area and the influence of the negative pressure area on the airflow.
进一步的，沿背向电机座100的方向，第一罩体210的内壁逐渐靠近第二罩体220，从而第二风道240出风侧的开口度减小，能够加大气流排出后的风压；并且，第一罩体210内壁的变化趋势与第一安装部111的变化趋势相同，可以同时起到供连接件400插接的作用。Further, along the direction away from the motor base 100, the inner wall of the first cover body 210 gradually approaches the second cover body 220, so that the opening degree of the air outlet side of the second air duct 240 is reduced, which can increase the airflow after the airflow is discharged. Moreover, the changing trend of the inner wall of the first cover body 210 is the same as the changing trend of the first mounting part 111, and can simultaneously play a role for the connector 400 to be inserted.
