Description

具有外包围保护的扇叶及使用该扇叶的风扇
技术领域
本发明涉及一种具有外包围保护的扇叶及使用该扇叶的风扇。
背景技术
眼角膜的成分是胶原纤维，胶原纤维为粘弹性体，有明显的滞后应力松弛特性，很小的应变就会引起很高的应力，刚性很强。在拉伸试验中，胶原纤维与开始时稍有伸长，但随着载荷增加，其强度迅速增大直至到达屈服点，其后就会发生非弹性变形。正常情况下，胶原纤维的变形范围为6%～8%，破坏时的最大应变也只有10%～15%。纤维电镜测量直径为20～100nm，胶原纤维的抗拉力值在100～1000N。
部分风扇为提高便携性能而采用无护罩、轻质扇叶的设计理念，但是相应地，其产生的风力较小，故需要尽量的接近人体才能让用户享受风扇带来的清风。由于没有防护，可能会刮到人的皮肤或眼球。根据牛顿第二运动定律F=M*A，即力量等于质量乘以速度。速度V=S/T，即路程除以时间。另外现有的小风扇每分钟转速为300转以上，只要测出风扇的直径和重量即能算出扇叶刮擦或碰撞人体时的力量。轻质扇叶通常采用塑料薄片制成，假如与人体发生冲击，其受力面积较小，导致扇叶对人体的很高的压强，使得人体容易受伤。
传统的吊扇是设置在房顶的铁质吊扇，随着电动机的小型化以及人们的需要，出现了外壳和扇叶本体由塑料制成的小型吊扇。这样的小吊扇风力较小，故需要尽量的接近人体，以让人们能享受吊扇带来的清风。由于没有防护，同时扇叶本体的厚度较薄，故一些较高的人接近电扇时，扇叶本体的外沿会刮到人的皮肤或眼球。较薄扇叶本体对人体冲击时，人体的受力面积较小，导致扇叶本体对人体的很高的压强，使得人体容易受伤。特别是现在很多家长会在婴儿床上安装此类吊扇，对新生婴儿存在很大的安全隐患，而一些座式风扇存在同样的问题。
发明内容
本发明要解决的技术问题是：提供具有外包围保护的扇叶及使用该扇叶的风扇,它可以避免扇叶本体外沿对人体的伤害。
本发明解决其技术问题的解决方案是：
具有外包围保护的扇叶，包括具有轴心的塑料扇风体，所述扇风体包括若干个扇叶本体，所有的扇叶本体以轴心为基点圆形阵列设置，扇风体还包括包围圈，所有扇叶本体均设置在包围圈内，至少有两个扇叶本体与包围圈连接，所述包围圈的硬度为90D以下。
作为上述方案的进一步改进，扇叶本体与包围圈非一体成型。
作为上述方案的进一步改进，所有的扇叶本体均与包围圈连接。
作为上述方案的进一步改进，包围圈的厚度为H，H>1mm，包围圈的直径为B，B＞200mm.
一种吊扇，包括上述的具有外包围保护的风扇。
一种吊扇，包括上述的具有外包围保护的风扇，包围圈有孔。
一种座扇，包括上述的具有外包围保护的扇叶，还包括与扇风体连接的风扇座。
本发明的有益效果是：具有外包围保护的扇叶，包括具有轴心的塑料扇风体，所述扇风体包括若干个扇叶本体，所有的扇叶本体以轴心为基点圆形阵列设置，扇风体还包括包围圈，所有扇叶本体均设置在包围圈内，至少有两个扇叶本体与包围圈连接，所述包围圈的硬度为90D以下。由于有包围圈的保护，可防止扇叶本体的外沿伤害用户，能起到很好的保护作用，通过大量的计算和实验，包围圈的硬度为90D的扇叶本体配合包围圈可有效防止皮肤和眼部的损伤。本发明还提供一种使用上述具有外包围保护的扇叶的吊扇和座扇。本发明用于风扇。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单说明。显然，所描述的附图只是本发明的一部分实施例，而不是全部实施例，本领域的技术人员在不付出创造性劳动的前提下，还可以根据这些附图获得其他设计方案和附图。
图1是本发明扇叶实施例的俯视示意图；
图2是本发明扇叶实施例的主视示意图。
具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。另外，文中所提到的所有联接/连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少联接辅件，来组成更优的联接结构。本发明中的各个技术特征，在不互相矛盾冲突的前提下可以交互组合。
参照图1和图2，这是本发明的扇叶实施例，具体地：
具有外包围保护的扇叶，包括具有轴心的塑料扇风体，扇风体裸露在外，所述扇风体包括若干个扇叶本体1，所有的扇叶本体1以轴心为基点圆形阵列设置，由于风扇体裸露在外所以扇叶本体1在高速转动下会对人体造成损伤，扇风体还包括包围圈2，扇叶本体1和包围圈2均作为独立构件两者非一体成形，所有扇叶本体1均设置在包围圈2内，至少有两个扇叶本体1与包围圈2连接，所述包围圈2的硬度为邵氏硬度90D以下。由于有包围圈的保护，可防止扇叶本体的外沿伤害用户，能起到很好的保护作用，通过大量的计算和实验，包围圈的硬度为90D的扇叶本体配合包围圈可有效防止皮肤和眼部的损伤。
为了减轻重量以及增大进气量，包围圈2上设有多个孔21。
