如图 6至 18所示， 本实用新型所述的鼓风机， 包括蜗牛座 6、 蜗牛盖 4、 风叶 7及电机 3 , 蜗牛座 6及蜗牛盖 4组成压缩排风风道， 压缩排风风道的出口处设有风网 5， 所述风叶 7 水平设于压缩排风风道内， 该风叶上部的蜗牛盖 4设有一体成型的电机安装腔 41， 该电机安 装腔 41内设有至少 4个电机安装脚 42 (如图 11所示）。 上述电机安装腔 41上部设有电机罩 1， 电机安装腔 41及电机罩 1组成进风风道， 所述电机 3垂直设于进风风道内并与其下部风 叶 7连接，即电机 3安装在电机安装腔 41与电机罩 1组成的空间内并通过电机轴与其下面的 风叶 7连接， 进而为风叶 7提供动力。

如图 6所示， 上述蜗牛盖 4上设有密封的电容接线盒 8， 上述电容接线盒 8由电容接线 腔 82和电容接线盖 81密封接合组成。 如图 11、 12和 13所示， 电容接线腔壁的上缘为密封 骨 821， 而电容接线盖 81对应的位置上设有密封槽 811， 密封骨 821和密封槽 811密封接合， 从而使电容接线腔 82和电容接线盖 81密封接合。如图 6所示，上述电容接线盖 81上设有开 关 9， 开关 9上面设有开关防护罩 86。如图 6和 10所示， 上述开关 9安装在开关压板 10上， 且开关 9与开关压板 10及电容接线盖 81之间设有防水密封开关护套 85， 电容接线盖 81在 安装防水密封开关护套对应的位置上设有开关护套密封骨 812。 进一步， 如图 10所示， 上述 电容接线盒 8内设有电容 83 ;上述电容接线腔 82—侧壁上设有电源线槽 822 (如图 11所示）； 上述电容接线盖 81上设有电机引线通孔 813， 且电源接线通孔 813上设有电源线护线套 84 (如图 6、 10和 12所示）， 为了加强防水， 其安装后采用密封胶密封。
进一步具体， 如图 6和 16所示， 上述蜗牛座 6底部设有至少三个脚支撑 61， 脚支撑 11 上设有至少一个地钉安装孔 611， 用以在放置草地时可通过地钉安装孔 611扎入地钉固定， 脚支撑 61设置令鼓风机运行更稳定， 同时又能防止地面积水水淹带来的危害。
进一步， 如图 16所示， 上述蜗牛座 6上设有止口槽 62， 而上述蜗牛盖 4上设有止口骨
44， 蜗牛座 6和蜗牛盖 4安装时， 止口槽 62和止口骨 44配合， 然后再采用螺栓通过螺栓安 装孔进行固定。 上述蜗牛座 6和蜗牛盖 4组成的压缩排风风道出口处设有椭圆形风网安装槽 500用于安装风网 5。进一步， 如图 17所示， 上述风网 5为塑钢风网， 其包括不锈钢网 51及 风网护套 52， 其采用不锈钢网 51的折边插入风网护套 52的固定槽里， 然后再注入环氧树脂 凝固固定为一整体， 该风网的特点主要是防锈及无毛剌， 可避免安装时刮伤手等。
再进一步， 为了携带方便， 如图 6所示， 上述电机罩 1上设有手提把 12。 而为了进一步 节约空间， 如图 18所示， 上述手提把 12为可折叠的手提把， 其通过铰接轴安装于电机罩 1 的安装座上。
本实用新型工作原理为： 当电机 4通电后驱动风叶 3时气流从外界通过电机罩 1上的条 状进风口 11吸入进风风道内再分别从电机的侧面及 （电机的后端盖 32通过电机内部从前端 盖 31排出）吸入至压缩排风风道内，最后通过风叶 7产生的离心力把气体从压缩排风风道甩 出。
本实用新型结构科学简洁， 风叶水平设置， 使整机重心均衡， 不易翻倒， 使用安全； 且 电机垂直设置在风叶的上部， 由电机罩进风口吸入的空气可以对电机起到风冷作用， 有效降 低电机的温升， 提高了电机的效率， 节能环保， 延长电机寿命。 电机置于风叶上部， 有效保 证距地面的距离， 解决了电机被水淹的问题， 加上电容接线盒盒的密封设计与电机两端的防 水保护， 提供良好的防水保护。 此实用新型发明是一种重心均衡， 节能环保， 防水优良的特 别适合室外使用的新型鼓风机。
