如图1至图3所示,本申请的一些实施例中,一种轴流风扇的导风结构1,所述导风结构1包括第一内圈101、外圈102以及多个第一栅条103;所述第一内圈101与所述外圈102均为环形,所述外圈102环绕设于所述第一内圈101的外围,各所述第一栅条103均在所述第一内圈101的周向上均匀间隔分布,并且一端与所述第一内圈101连接,另一端与所述外圈102连接;各所述第一栅条103均呈螺线延伸的扭曲片状。上述设计减小了空气在流经所述导风结构1时遇到的阻力和摩擦,进而减小由气流与所述导风结构1摩擦时产生的噪音。
本申请的一些实施例中,所述第一内圈101的直径是所述外圈102的直径的0.1-0.3倍,上述涉及可以减小空气在流经所述导风结构1时受到的阻力和摩擦,从而减小气流与所述导风结构1摩擦产生的噪音。可以理解的是,在其他参数不变的情况下,当所述第一内圈101的直径越小,则所述第一栅条103的延伸方向上的尺寸越大,越有利于汇聚风力、增大所述导风结构1的送风量以及扩大送风范围。
如图2所示,本申请的一些实施例中,所述第一内圈101的径向的所在平面与所述外圈102的径向的所在平面不在一个平面内且相平行。可以理解的是,所述第一内圈101、外圈102以及第一栅条103围合形成一碗状空间,该空间可以部分或完全容纳风扇或风扇灯的扇叶,可以提供空间利用率,减小了风扇或风扇灯的整机体积。
具体的,本申请的一些实施例中,所述第一内圈101的径向的所在平面与所述外圈102的径向的所在平面之间的垂直距离小于或等于所述外圈102的直径的5-10%。示例性地,该垂直距离可以小于或等于所述外圈102的直径的6%、7%、8%或者9.5%中的任意一个。当然,在本申请的另一些实施例中,该垂直距离也可以有其他取值范围,具体可根据实际需求加以选择和调整。
如图3所示,本申请的一些实施例中,所述第一栅条103包括第一端1031和第二端1032,所述第一栅条103的第一端1031与所述第一内圈101连接,所述第一栅条103的第二端1032与所述外圈102连接;所述第一栅条103的第一端1031的中点与所述第一内圈101的中心的连线在所述外圈102的径向的所在平面上的投影为第一连线1061,所述第一栅条103的第二端1032的中点与所述第一内圈101的中心的连线在所述外圈102的径向的所在平面上的投影为第二连线1062,所述第一连线1061与所述第二连线1062相交形成第一夹角106,所述第一夹角106的取值范围为小于或等于75°,并且大于50°。该设计使得所述导风结构1对于通过它的气流表现出更小的阻力和摩擦,使气流经过时产生的噪音更小,并且对于流经所述导风结构1的气流具有倒流效果,因此能够扩大所述导风结构1的导风影响半径,扩大了所述导风结构1的送风范围。
可以理解的是,所述第一栅条103的第一端1031的中点,指的是所述第一栅条103的第一端1031的宽度方向上的中点;所述第一栅条103的第二端1032的中点,指的是所述第一栅条103的第二端1032的宽度方向上的中点。
本申请的一些实施例中,所述第一栅条103的延伸方向上的各处位置在其宽度方向上的尺寸可以不相同,可以是沿着自所述第一栅条103与所述外圈102的连接处指向所述第一栅条103与所述第一内圈101的方向而逐渐减小或逐渐增大。
示例性地,所述第一夹角106的数值大小可以是55°、60°、65°以及70°中的任意一个,具体取值可根据实际需求加以选择和调整。
如图1所示,本申请的一些实施例中,所述导风结构1还包括第二内圈104和第二栅条105;所述第二内圈104为环形,并且围设于所述第一内圈101的内周;所述第二栅条105的两端分别与所述第一内圈101和第二内圈104相连接。可以理解的是,所述第二栅条105的形状及尺寸均可根据实际需求进行选择和调整。
如图2和图3所示,本申请的一些实施例中,各所述第一栅条103在其厚度方向上均具有一迎风表面1033,各所述第一栅条103的迎风表面1033均面向所述外圈102的径向的所在平面;各所述第一栅条103的迎风表面1033与所述外圈102的径向的所在平面之间具有第二夹角107,所述第二夹角107的取值范围为大于或等于50°,并且小于90°;各所述第一栅条103的所述迎风表面1033上的各处位置的所述第二夹角107的数值大小和方向具有连续关系。该设计使得所述导风结构1对于通过它的气流具有较小的阻力和摩擦,使得气流经过时产生的噪音更小,并且对于流经导风结构1的气流具有倒流效果,因此能够扩大所述导风结构1的导风影响半径,扩大了所述导风结构1的送风范围。
示例性地,所述第二夹角107的数值大小可以是55°、60°、65°、70°、75°、80°、85°中的任意一个,具体取值可以根据实际需求加以选取和调整。
如图2和图3所示,本申请的一些实施例中,所述第一栅条103的迎风表面1033上各处位置的所述第二夹角107沿着自所述第一栅条103与所述外圈102的连接处指向所述第一栅条103与所述第一内圈101的连接处的方向连续减小;所述第一栅条103与所述外圈102的连接处的迎风表面1033的所述第二夹角107和所述第一栅条103与所述第一内圈101的连接处的迎风表面1033的所述第二夹角107之间的差值小于或等于5°;上述设计可以在有效汇聚风力、提高送风量的同时减小风阻和风噪。示例性地,上述差值的具体大小可以设定为3°、7°或10°,具体取值可根据实际需求加以选择和调整。
实施例2
如图4和图5所示,本申请的一些实施例中,一种风扇灯,包括光源2、扇叶3、电机4、支架5以及如实施例1中所述的导风结构1;所述电机4与所述导风结构1均与所述支架5固定连接,所述扇叶3与所述电机4连接,并位于所述导风结构1和支架5之间;所述光源2固设于所述导风结构1的外圈102的外围,和/或,所述导风结构1的第一内圈101内;各所述第一栅条103在其厚度方向上均具有一迎风表面1033,各所述第一栅条103的迎风表面1033均面向所述导风结构1的径向的所在平面;所述扇叶3的旋转平面与所述导风结构1的径向的所在平面相平行,所述扇叶3的出风方向垂直于所述扇叶3的旋转平面,所述迎风表面1033朝向所述扇叶3的出风方向。上述的风扇灯具有出风影响范围大且风噪小的优点。
如图4和图5所示,本申请的一些实施例中,所述扇叶3的形状和旋转方向均与所述导风结构1中的第一栅条103的延伸方向相适应。上述设计可使所述扇叶3产生的气流在吹向所述迎风表面1033时遭遇到的阻力更小,并由此减小了由风阻产生的噪音。
如图4和图5所示,本申请的一些实施例中,各所述第一栅条103的迎风表面1033均面向所述外圈102的径向的所在平面;所述第一栅条103的迎风表面1033上各处位置的所述第二夹角107沿着自所述第一栅条103与所述外圈102的连接处指向所述第一栅条103与所述第一内圈101的连接处的方向连续减小;所述第一栅条103与所述外圈102的连接处的迎风表面1033的所述第二夹角107和所述第一栅条103与所述第一内圈101的连接处的迎风表面1033的所述第二夹角107之间的差值小于或等于5°;上述形状的第一栅条103可减小风阻降低风噪。
可以理解的是,位于所述迎风表面1033上的各处位置的所述第二夹角107的数值大小和方向均具有连续关系,即假设所述迎风表面1033上某一点的所述第二夹角107的大小为75°,那么该点附近范围内各邻近点的所述第二夹角107的大小是以75°为基准上下浮动且连续的,这是由所述迎风表面1033是一个以螺线状延伸的弧面的本质决定的。本申请的一些实施例中,位于所述迎风表面1033上的各处位置的所述第二夹角107在数值大小上的最大波动范围不超过10°,该允许的最大波动范围也可根据实际需求进行选择和调整;可以理解的是,所述第二夹角107的波动最大值一般是出现在所述迎风表面1033与所述第一内圈101的连接处,所述第二夹角107的波动最小值一般是出现在所述迎风表面1033与所述外圈102的连接处。本申请的一些实施例中这两个位置的所述第二夹角107在数值大小上的差值不超过5°。
本申请的一些实施例中,所述第二夹角107大于或等于50°,并且小于或等于90°。上述设计可使气流在吹向所述迎风表面1033时遭遇到的阻力更小,并由此减小了由风阻产生的噪音,并且对于流经所述导风结构1 的气流具有倒流效果,因此能够扩大所述导风结构1的导风影响半径,扩大了所述导风结构1的送风范围。示例性地,所述第二夹角107的取值可以是55°、60°、65°、70°、75°、80°、85°中的任意一个,具体取值可根据实际需求加以选择和调整。
本申请的一些实施例中,所述光源2包括灯盘、灯罩以及灯珠;所述灯珠设于所述灯盘上,所述灯罩覆盖设置于所述灯盘上进而包合所述灯珠;所述灯珠的数量以及在所述灯盘上的分布均可根据实际需求进行设计和选择。
本申请的一些实施例中,所述风扇灯还包括一螺母,所述螺母设于所述导风结构1和扇叶3之间,通过拧紧锁定的方式将所述导风结构1和扇叶3固定。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。此外,说明书中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请的方法及其核心思想,本说明书内容不应理解为对本申请的限制。
