具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
请参阅图1和图7所示，本申请揭示了一种风扇灯100，包括外壳2、出风结构1和光源组件，所述外壳2罩设在所述出风结构1的外侧并与所述出风结构1固定连接，所述风扇灯100的底部凹设有光学腔，所述光源组件装配在所述光学腔内。所述光学腔可以设置在所述出风结构1和外壳2的其中之一的底部，可根据实际情况进行调整，对此不作限制。
请结合图6所示，所述外壳2上设有进风口21，所述出风结构1设有出风口10，所述进风口21和所述出风口10相互连通，所述出风结构1运行时，带动外部气流自所述进风口21进入所述风扇灯100内部，并经所述出风口10排出。
当然的，所述出风结构1并不限于安装在风扇灯100内，也可以适用于其他风扇，对此不做限制。
所述出风结构1包括壳体11和风机组件12，所述壳体11内凹设有装配槽110，所述风机组件12装配在所述装配槽110内，并被所述壳体11隐藏，以确保使用安全。
所述风机组件12包括叶轮组件121和电机组件122，所述电机组件122驱动所述叶轮组件121转动，以带动外部气流流入所述出风结构1，并自所述出风口10排出。在正对所述装配槽110的方向，所述叶轮组件121收容在所述装配槽110内并被所述壳体11遮挡，所述电机组件122能被观测到。
具体的，请结合图2和图3所示，所述壳体11顶部设有装配口114，所述装配槽110包括被所述壳体11遮挡的第一装配槽1101以及曝露于所述装配口114的第二装配槽1102，所述第一装配槽1101、所述第二装配槽1102以及所述出风口10相互连通，所述叶轮组件121装配在所述第一装配槽1101内，所述电机组件122装配在所述第二装配槽1102内。
所述壳体11包括基体111和自所述基体111向外延伸的外延部112，所述外延部112设有多个且环设在所述基体111的外周，所述装配槽110凹设在所述基体111内，所述外延部112内设有风腔1120，所述出风口10设置在所述外延部112上，所述风腔1120、所述出风口10和所述装配槽110相互连通，从而所述叶轮组件121运行时能够带动外部气流自所述装配槽110进入，并从所述叶轮组件121的周向流出，经所述风腔1120后从所述出风口10排出。
优选的，所述出风口10环设在所述光学腔的外周，以使得出风方向和出光方向相同。在本实施例中，所述光源组件向下出光，所述出风口10沿所述壳体11的中轴线113方向向下开口，使所述出风结构1向下出风。当然，在其他实施例中，可以根据实际情况对出风方向和光源组件的出光方向做出调整，对此不作限制。
优选的，相邻两个外延部112之间设有镂空区域13，多个镂空区域13和多个外延部112拼合成一完整的圆环，单个所述镂空区域13的面积为单个所述外延部112的面积的1/3至1/2。也就是说，所述外延部112为多个独立的部件，其环设在所述基体111上，可一体成型，也可以拆卸的设置，对此不作限制。
所述壳体11的内部还设有与所述镂空区域13相对应的导流部131，所述导流部131分隔相邻两个风腔1120，并将从所述风机组件12周向流出的气流引入所述风腔1120内部。
在所述壳体11的中轴线113方向上，多个所述出风口10绕所述中轴线113呈圆环状排布，且在所述出风口10的排布方向上，所述出风口10一端的宽度小于另一端的宽度。如此一来，宽度较小的一端的风速大于宽度较大的一端的风速，这样能使得使用者明显感受到风感。
具体的，所述出风口10包括呈同心设置的内缘边101和外缘边102，定义所述中轴线113至所述内缘边101的距离为所述出风口10的内径a，所述中轴线113至所述外缘边102的距离为所述出风口10的外径b，所述内径a与所述外径b的比值为所述出风口10的内外径比，所述出风口10一端的内外径比大于另一端的内外径比。

优选的，所述第二弧段1022位置处对应的内外径比占所述第一弧段1021位置处对应的内外径比的60％-80％，如此设置，能最大程度的保证出风效率。在本实施例中，所述内径a的大小不变，所述外径b大小随所述外缘边102不同的弧段发生变化；当然，在其他实施例中，也可以是外径b的大小不变，通过调整所述内缘边101的弧段，来改变内径a的大小，从而改变内外径比。
优选的，所述第一弧段1021的长度占所述外缘边102长度的2/3至3/4。在本实施例中，所述第一弧段1021到所述中轴线113的距离小于所述第二弧段1022至所述中轴线113的距离，也就是说，所述第一弧段1021对应的出风口10的宽度较窄，而其占据的长度也是较所述第二弧段1022更长。
在所述壳体11的中轴线113方向上，所述外延部112整体呈弧形设置，使得所述出风口10位于所述基体111的下方。所述外延部112包括连接所述基体111和所述外缘边102的上弧面1121，以及连接所述基体111和所述内缘边101的下弧面1122，定义所述上弧面1121具有第一切线，所述下弧面1122具有第二切线，所述第一切线和所述第二切线相互平行。如此，使得所述外延部112整体大小均匀，保证了出风均匀性。
优选的，所述第一切线和所述第二切线与所述中轴线113之间的夹角均位于20°-40°之间。经实验证明，这个结构下的外延部112出风效果最好。
优选的，所述上弧面1121的与所述外缘边102相连的一端具有第一连接面11211和第二连接面11212，所述第一连接面11211朝靠近所述中轴线113的方向延伸，并与所述第一弧段1021相连，所述第二连接面11212与所述第二弧段1022相连。也就是说，通过控制所述第一连接面11211和第二连接面11212在垂直于所述中轴线113方向上的朝向，来控制所述出风口10的开口方向，如此，即控制了所述出风结构1的出风方向。
优选的，所述第二连接面11212的延伸方向与所述中轴线113的方向平行；或者，所述第二连接面11212朝远离所述中轴线113的方向延伸。如此，使得所述第一连接面11211对应的出风口10的出风方向和所述第二连接面11212对应的出风口10的出风方向不同，来扩大出风范围。
当所述第二连接面11212朝向远离所述中轴线113的方向延伸时，能进一步扩大所述出风结构1的出风方向，当然，实际的角度可以根据实际情况进行调整，对此不做限制。
综上所述，本申请的出风结构1及风扇灯100通过在壳体11的基体111的外周设置外延部112，使得所述基体111的装配槽110、所述外延部112的风腔1120以及出风口10相互连通，通过将所述出风口10两端设置成不同的宽度，使得所述出风结构1能够在保证中心风速和最大出风量的同时，控制出风方向。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
