And the third fan blade part 30. Wherein, the diameter of the second fan blade part 20 is between the first fan blade part 10 and the third fan blade part 30. For example, the size relationship of the diameter of each blade part is: the first blade part 10>the second blade part 20>the third blade part 30, or the third blade part 30>the second blade part 20>the first blade part. A fan blade part 10. In this way, by adjusting the second fan blade portion 20 to be close to and sleeved relative to the first fan blade portion 10, and the third fan blade portion 30 to be close to and sleeved relative to the second fan blade portion 20, the length of the cross flow fan can be further shortened.

In this way, a cross-flow fan with a longer length can be assembled to expand the air supply range of the cross-flow fan.
可选地,第一扇叶部10直径>第二扇叶部20直径>第三扇叶部30直径,第一扇叶部10、第二扇叶部20和第三扇叶部30均为两个,从左至右依次同轴套接第三扇叶部30、第二扇叶部20、第一扇叶部10、第一扇叶部10、第二扇叶部20和第三扇叶部30。这样,形成的贯流风扇从中间到两端直径逐渐减小,实现送风中间强两端弱的效果,提升用户体验。可选地,第三扇叶部30的长度长于第一扇叶部10和第二扇叶部20。这样也是一种贯流风扇的组合方式,能够扩大弱风范围。Optionally, the diameter of the first blade portion 10>the diameter of the second blade portion 20>the diameter of the third blade portion 30, and the first blade portion 10, the second blade portion 20, and the third blade portion 30 are all Two, coaxially sleeve the third fan blade part 30, the second fan blade part 20, the first fan blade part 10, the first fan blade part 10, the second fan blade part 20 and the third fan in order from left to right Leaf 30.

Optionally, the length of the third fan blade part 30 is longer than the first fan blade part 10 and the second fan blade part 20. This is also a combination of cross-flow fans, which can expand the range of weak winds.
在一些实施例中,结合图7所示,第一扇叶部10包括围成筒状的多个第一叶片101,第一扇叶部10的直径大于第二扇叶部20的直径。这样,在调节贯流风扇长度时,第二扇叶部20的一端可缩入第一扇叶部10。可选地,第一叶片101的数量多于第二叶片201。当第二扇叶部20的直径小于第一扇叶部10时,第二叶片201的数量少于第一叶片101,一方面能够避免因直径减小而导致的叶片间距减小,进而影响进风,另一方面可以减少叶片的用量。第二叶片201数量减少,在第一扇叶部10和第二扇叶部20部分交叠时,可以降低对进入第一扇叶部10的气流的流动影响。第二叶片201数量的减少可以使连接圈11上的过孔12数量减少或者面积减少,从而减少对连接圈11机械强度的影响,使连接圈11保持牢固稳定。第二叶片201数量减少也能够使固定部212相对叶片的径向延伸长度更长,这是因为第二叶片201数量减少相应地相邻固定部212之间的距离增大,固定部212可以径向延伸更长,这样,固定部212更能避免第二叶片201从过孔12中脱出。由于第一扇叶部10的直径大于第二扇叶部20,在贯流风扇转动时,第一扇叶部10的送风量大于第二扇叶部20的送风量,能够使贯流风扇在空调外部产生强送风区域和弱送风区域。In some embodiments, as shown in FIG. 7, the first fan blade portion 10 includes a plurality of first blades 101 surrounded in a cylindrical shape, and the diameter of the first fan blade portion 10 is larger than the diameter of the second fan blade portion 20. In this way, when the length of the cross-flow fan is adjusted, one end of the second fan blade portion 20 can be retracted into the first fan blade portion 10. Optionally, the number of the first blades 101 is more than that of the second blades 201. When the diameter of the second blade portion 20 is smaller than that of the first blade portion 10, the number of the second blades 201 is less than that of the first blades 101. On the one hand, it can avoid the reduction of the blade pitch caused by the diameter reduction, which will affect the progress. Wind, on the other hand, can reduce the amount of blades. The number of the second blades 201 is reduced, and when the first fan blade portion 10 and the second fan blade portion 20 partially overlap, the influence on the flow of the airflow entering the first fan blade portion 10 can be reduced. The reduction in the number of the second blades 201 can reduce the number or area of the vias 12 on the connecting ring 11, thereby reducing the impact on the mechanical strength of the connecting ring 11, and keeping the connecting ring 11 firm and stable. The reduction in the number of the second blades 201 can also make the fixed portion 212 have a longer radial extension relative to the blades. This is because the reduction in the number of the second blades 201 correspondingly increases the distance between the adjacent fixed portions 212, and the fixed portion 212 can have a larger diameter. It extends longer in the direction, so that the fixing portion 212 can better prevent the second blade 201 from falling out of the via hole 12. Since the diameter of the first blade portion 10 is larger than that of the second blade portion 20, when the cross flow fan rotates, the air volume of the first blade portion 10 is greater than the air volume of the second blade portion 20, which can make the cross flow The fan creates a strong air supply area and a weak air supply area outside the air conditioner.

It can be used in applications with low rotation speed and has a large diameter.
在一些实施例中,第二叶片201的宽度大于第一叶片101的宽度。在第二叶片201数量减少的基础上,第二叶片201的宽度大于第一叶片101宽度,这样能够增强第二扇叶部20的结构强度,使第二叶片201更加牢固稳定,降低第二扇叶部20旋转时产生的振动噪音。第二扇叶部20由于减少了叶片数量,机械强度低于第一扇叶部10,增大第二叶片201的宽度。并且,第二叶片201的宽度增大,能够适当增加送风量,避免第二扇叶部20的送风量下降过多。可选地,第二叶片201的厚度大于第一叶片101的厚度。厚度增加能够增强第二叶片201的机械强度,使其在连同第一扇叶部10共同旋转时更加坚固不易弯曲变形。In some embodiments, the width of the second blade 201 is greater than the width of the first blade 101. On the basis of the reduction in the number of second blades 201, the width of the second blade 201 is greater than the width of the first blade 101, which can enhance the structural strength of the second blade portion 20, make the second blade 201 more stable and stable, and reduce the second blade. Vibration noise generated when the blade 20 rotates. Due to the reduction of the number of blades in the second fan blade portion 20, the mechanical strength is lower than that of the first fan blade portion 10, and the width of the second blade 201 is increased. In addition, the width of the second blade 201 is increased, and the air blowing volume can be appropriately increased, and the air blowing volume of the second blade portion 20 can be prevented from excessively decreasing. Optionally, the thickness of the second blade 201 is greater than the thickness of the first blade 101. The increase in thickness can enhance the mechanical strength of the second blade 201 and make it stronger and less susceptible to bending and deformation when rotating together with the first blade portion 10.

The main body is in the shape of a belt; the contraction part is arranged on the main body and has a width smaller than the width of the main body. The width of the constricted part is smaller than the width of the main body. When the airflow passes through the constricted part of the blade, the wind pressure of the airflow can be enhanced, thereby increasing the air outlet pressure of the cross-flow fan. Optionally, the constriction is provided at the middle or end of the main body. In this way, the supercharging effect on the airflow can be achieved.
