Description

吹风头无风叶电风扇
技术领域
本发明涉及各种家用电风扇，特别涉及一种吹风头无风叶电风扇。
背景技术
现有的各种电风扇风的来源都是采用风叶直吹式结构，这种风叶直吹式结构电扇在使用过程中都存在着各种安全隐患，特别是在清洗过程中还带来种种不便。
发明内容
为此，本发明所要解决的技术问题是提供一种外形美观、清洗方便、使用安全的吹风头无风叶电风扇。
本发明吹风头无风叶电风扇包括底座、机壳、风机电机、离心风叶、吹风头、摇头电机，吹风头与机壳同体相连，吹风头四圈是空心风道，风机电机与离心风叶同轴连接，电机轴与离心风叶连接头的一端装有安全螺母，安全螺母的作用是防止离心风叶与电机脱离，离心风叶的外面装有风机壳，风机壳的作用是把离心风叶吸入风压力增大，通过风道使吹风头有强风吹出，外壳下面开有进风孔，外壳下端中心处是外壳轴座，底座上面装有中心轴，中心轴上面装轴承，轴承与外壳轴座连接转动，摇头电机安装在底座底部，摇头小齿通过键销安装在摇头电机输出轴的一端，摇头大齿轮与摇头小齿轮啮合转动，摇头大齿轮通过键销与轴连接，轴另一端装有轴承，轴承安装在支座上面，支座与底座相互连接，摇头大齿轮半径中心处装有摆臂，摆臂与机壳底部活动连接。
本发明的工作原理是这样的：当风机电机通电旋转时带动与风机电机轴同轴连接的离心风叶高速转动，离心风叶的高速转动使风机壳内部产生高速高压风流，因风机壳的特殊结构和密封作用，结合离心风叶的特定旋转方向，风机壳内的高速高压风流在离心风叶不断转动作用下，由机壳外的进风孔进入，通过机壳上的风道流向吹风头，使吹风头四圈有风吹出。
当吹风头需要摆动吹风时，接通摇头电机电源，这时摇头电机转动带动与摇头电机轴同轴连接摇头小齿轮转动，同时也使与摇头小齿轮啮合摇头大齿轮转动，因摇头大齿轮半径中心处装有摆臂，摆臂摆动使与摆臂活动连接机壳左右摆动，实现了吹风头左右摆动吹风。
附图说明
图1为本发明实施例结构图；
图2为本发明实施例正视外形图；
具体实施方式
