以下结合附图实施例对本发明作进一步详细描述。
参见图 1至图 3-2， 一种 360度出风的电风扇， 采用离心式的风扇， 包括由上、 下 两部分对接形成的栅格状壳体 1， 设置在壳体 1下方的底座 2， 以及设置在底座 2下方 的角度调节座 3。
底座 2内设有驱动用的电机 21， 电机 21的输出轴 211从壳体 1下底部中心向上延 伸入壳体 1内。 底座 2的侧壁上设有幵关 22， 在本实施例中， 为按钮开关， 可以通过按 压按钮开关调节电机 21 的转速而调节下述叶轮的转速， 进而调节送风量， 优选的， 开 关 22为一键式按钮开关， 通过按键的次数选择开、 关和不同的档位， 如按键按压次数 为 1， 则电风扇开启并且档位处于高速档， 连接按压按键 2次则将档位换成中速档， 连 接按压按键 3次则将档位换成低速档， 连接按压按键 4次则关闭电风扇。 开关 22的背 面可以设有 LED灯作为背光源， 当电风扇与电源未导通时， LED灯不亮， 而导通时， LED灯点亮， 以便使用者了解电风扇是否通电。
壳体 1 内设有叶轮 11， 包括与电机 21的输出轴 211垂直的圆盘 111， 固定于圆盘 111中心的轴向延伸的中空轴 112， 以及环绕中空轴 1 12设置的叶片 113。 中空轴 112用 于与电机 21的输出轴 211配合， 输出轴 211的端部伸入到中空轴 112内并固定， 由此 当电机 21运行时， 其输出轴 211的旋转可以带动中空轴 112进而带动圆盘 111旋转。
叶片 113沿着中空轴 112的轴向穿过圆盘 111延伸， 在本实施例中， 叶片 113呈半 圆形， 并且平直的一侧与中空轴 112固定并平行， 并且在轴向上位于圆盘 111上方和下 方的两部分对称， 叶片 113至少部分， 如径向外侧的末端， 向叶片 113的旋转方向逐渐 弯曲， 依次使得叶轮 11送风具有更高的效率。 当然， 叶片 113也可以采用其他的形状， 如背景技术中所提及的文献中所述的。
角度调节座 3包括互相配合的第一调节板 31和第二调节板 32，第一调节板 31呈中 间低四周高的内凹状， 在第一调节板 31的下表面设有与第一调节板 31的整体形状弧度 一致的滑动部 311， 滑动部 311的两侧分别设有同样弧度和延伸方向的第一导向杆 312， 第一导向杆 312远离滑动部 311的外侧开设有第一导向槽 313(也可以开设在朝向滑动部 311的内侧)。 第二调节板 32的上表面上设有与滑动部 311配合的滑槽 321， 滑动部 311 可以在滑槽 321内滑动，在本实施例中，滑槽 321由两个平行间隔设置的滑杆 324形成， 滑动部 311位于两个滑杆 324之间， 并且沿着第二调节板 32的上表面滑动。 第二调节 板 32的滑槽 321的两侧分别设有与第一导向杆 312配合的第二导向杆 322，第二导向杆 322朝向滑槽 321的内侧开设有第二导向槽 323(也可以开设在远离滑槽 321的外侧)，将 第一导向杆 312的外侧置于第二导向槽 323内， 而第二导向杆 322的内侧置于第一导向 槽 313内， 由此两个导向杆可以沿着特定的方向 (导向杆的延伸方向)相对滑动， 参见图 4。 第一调节板 31固定在底座 2的下面， 第二调节板 32支撑在台面上， 以稳定的放置 电风扇。
第二调节板 32的下方设有固定板 33，第二调节板 32的下底面具有内凹的部分，固 定板 33位于内凹的部分内， 通过依次穿过固定板 33、 第二调节板 32和第一调节板 31 的固定件 (如螺栓等)可将两个调节板固定。
当需要调节出风平面时， 可抓紧第二调节板 32使其固定不动， 而使得底座 2通过 第一调节板 31在第二调节板 32上滑动到所需的位置， 此时， 底座 2相对水平面不再平 行而形成一定的角度， 即叶片 113和中空轴 112不再与水平面垂直， 由此可以向四周送 出位于不同平面的风， 从而适应不同场合的需要， 扩大了使用的范围。
在上文中， 第一调节板 31和第二调节板 32为中间低四周高的形状， 可替代的， 也 可以采用中间高四周低的形状，具有一定的弧度即可，这种情况下需要再设置限位部件； 或者第一调节板 31和第二调节板 32的表面为水平，此时导向杆、滑动部 311和滑槽 321 呈弧形， 并且此时滑动部 311不与相对调节板的表面接触， 而是在滑槽 321内滑动。 滑 动部 311和滑槽 321的位置可互换。
在上述实施例中，第一调节板 31和第二调节板 32之间通过一对滑动部和滑槽实现 一个方向的滑动。 可替代的， 在不使用导向杆的情况下， 也可以采用一个滑动部和对应 的两个滑槽的方式实现两个方向的滑动， 此时， 两个滑槽可呈垂直分布， 当滑动部沿着 第一个滑槽在一个方向上滑动一定距离到达与第二个滑槽的交叉处时，可改变方向后沿 着第二个滑槽在另一个方向 (与上一个方向垂直)上滑动， 由此使得出风平面更加的多样 化。
