本发明的优点在于降低了噪音， 提高了产品使用的舒适度。 附图说明
图 1A、 图 IB是本发明第一实施例示意图；
图 2A是图 1B的 A- A线剖视图；
图 2B是马达安装座的结构示意图。
图 3是本发明第一实施例的复数个凸起筋与马达安装座相互卡合的示 意图；
图 4A、 图 4B是本发明第二实施例的复数个四角秤锤的示意图。 具体实施方式
图 1A、 图 1B是本发明第一实施例示意图。 如图所示， 干手机 100， 设有机座 110和外壳 120， 还包括： 马达（图中未示)和扇页（图中未示）组 成的风扇马达 130， 在该风扇马达 130的吸风口（图中未示）侧设有马达安 装座 140， 该马达安装座 140向机座 110突出相连接， 形成向吸风口（图中 未示）指定方向的吸气风路，在上述吸风口和机座之间设有顺着气流方向 的复数个凸起筋 112。
机座 110正对着吸风口（图中未示）， 机座 110和吸风口（图中未示）间 设有空气流经的空间。 马达（图中未示）发出的噪音其中的很大部分在此空 间发散， 并传到机体外。 因此， 通过在吸风口（图中未示)和机座 110之间 的空间像上述那样设置复数个凸起筋 112的降噪音结构， 可以防止噪音的 发散， 降低噪音是有必要的。 而且， 通过加强机座 110和马达安装座 140 之间的密封性也可以降低噪音。
图 2A是图 1B的 A-A线剖视图， 图 2B是马达安装座的结构示意图。 如图 2A所示， 马达安装座 140具有向机座 110延设并与由马达 131和扇 页 132组成的风扇马达 130的吸风口 133为同心圆的第 1壁 141以及向机 座 110延设并与第 1壁 141的外侧为同心圆的第 2壁 142。 如图 2B所示， 在第 1壁 141的圆周的一处设有切口部 143,切口部 143的一侧设有与第 2 壁 142相结合的遮挡壁 144。 而且， 使马达安装座 140向机座 110突出相 连接，由第 1壁 141和第 2壁 142以及机座 110所包围的空间形成略呈 C 形状的通风路 145。
另外， 再如图 2A所示，机座 110上设有向马达安装座 140突出并与其 相连接的卡合突起 111。该卡合突 111为与上述第 1壁 141和遮挡壁 144 的形状相配合，从机座 110向马达安装座侧 140突出。而且，所说的使马达 安装座 140向机座 110突出并与其相连接，是指卡合突起 111与马达安装 座 140的端部 146相重叠卡合。
并且， 如图 2A和 2B所示，马达安装座 140下方设有吸入口 121， 从该 吸入口 121吸入的空气穿过由通风路 145，从由遮挡壁 144而隔离的上述切 口部 143的位置被引导至风扇马达 130中心部的吸风口 133。 SP,从吸入口 121吸入的空气，穿过由第 1壁 141和第 2壁 142所围成的 C形状的通风路 145到达切口部 143,相对风扇马达 130的吸风口 133， 其从横方向 （水平 方向） 被吸入。
通过上述通风路 145结构， 为使从吸入口 121被吸入的水滴不侵入到 风扇马达 130内， 确保其风路的长度是非常重要的， 同时， 使马达安装座 140和机座 110相互紧密相连也是很重要的。 因此， 马达安装座 140和机 座 110使设置在机座 110上的卡合突起 111和马达安装座 140的端部 146 相重叠卡合， 提高吸风口 133部分的密封性和防止水滴从吸入口 121进入 到马达内的同时,可以大大降低噪音。
图 3是本发明第一实施例的复数个凸起筋与马达安装座相互卡合的示 意图。如图所示，机座 110上的卡合突起 111和马达安装座 140的端部 146 相重叠卡合， 再通过固定螺丝 102将马达安装座 140固定于机座 110上。 机座 110上平行设置复数凸起筋 112， 而且， 这些复数突起筋 112设置于 被马达安装座 140的第 1壁 141所包围的部分的内侧。 而且， 吸风口（图 中未示）面向被该第 1壁 141所包围的部分设置。 像这样通过在机座 110 上设置凸起筋 112， 吸风口（图中未示）产生的噪音与凸起筋 112反复发生 碰撞而扩散。 此时， 能量逐渐减弱， 声压降低。 而且， 凸起筋 112的排列 方向为从上述切口部 143向吸风口（图中未示）设置， 并且复数凸起筋 112 平行设置， 是顺着空气流动的方向， 干手机吸入的空气向吸风口（图中未 示）方向被整流， 很顺畅地被风扇马达（图中未示）吸入。 因此， 吸风口（图 中未示)和机座 110之间设置凸起筋 112也不会对干手机 100的风量和风 速等性能产生影响。 也就是说，可以大大降低噪音。
图 4A、 图 4B是本发明第二实施例的复数个四角秤锤的示意图。 本发 明第二实施例是用复数个四角秤锤 113取代了第一实施例的复数个凸起筋 112 , 其余结构是相同的。 如图 4A所示， 在干手机 100的机座 110上设有 复数个面向吸风口（图中未示）的四角秤锤 113， 将面向吸风口（图中未示） 的机座 110的表面分割为多个互相交错分布的平面。 马达（图中未示)发出 的噪音的声波传到机座 110上时， 在多个面上产生多次反复反射， 此时， 声波的能量逐渐减弱， 从而噪音降低。
再如图 4B 所示，在本实施例中， 吸风口 133 和机座 110 的间隔为
HJ3- 16讓之间， 四角秤锤 113的高度 为 4-7讓之间， 其四角秤锤 113 顶部和吸风口 133间有一定的间隔， 不接触吸风口 133。 因此， 不会对干 手机 100的风量和风速等性能产生影响， 不会阻碍吸入的气流。
