具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本发明的描述中,需要理解的是,术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周 向”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
需要说明的是,在本发明的描述中,术语“第一”、“第二”仅用于方便描述不同的部件,而不能理解为指示或暗示顺序关系、相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。
实施例1:
参照图1,本实施例提供一种风扇,风扇包括:风扇组件以及底座组件2,其中,底座组件2包括支撑杆,风扇组件又可以称为风扇本体1,风扇本体1安装于底座组件2的支撑杆上。由此,底座组件2对风扇组件起到了支撑作用。使用时,该底座组件2可以放置在地面上,也可以放置在桌面或者工作台等平台上。
参照图2,风扇组件具体包括风扇头以及连接臂6,连接臂6的一端与风扇头连接,连接臂6的另一端与支撑杆连接,以将风扇头安装于底座组件2的支撑杆上。
可以理解的是,如图5所示,风扇头包括风扇罩、设置在风扇罩内的扇叶组件11和电机组件10,电机组件10驱动扇叶组件11转动以形成气流,气流从风扇罩吹出,以实现送风。
其中,如图4所示,风扇罩包括由前至后布置的前罩8和后罩7,前罩8和后罩7可拆卸式装配。由此,前罩8和后罩7可以拆开,前罩8可以拆卸下来,进而可以对前罩8单独进行清洗,也便于擦拭扇叶组件11上的灰尘。这里,前指的是朝向气流吹出的方向,后指的是背离气流吹出的方向。
连接臂6与风扇罩,具体是与后罩7可拆卸连接,以使风扇罩可拆卸地安装于底座组件2的支撑杆上。由此,风扇罩可以从连接臂6上拆卸下来,进而可以风扇头进行清洗。
下面参考附图详细的描述连接臂6的结构和功能。
参照图3,本实施例提供的连接臂6包括连接臂本体17,连接臂本体17的两端分别用于与支撑杆和风扇罩连接。其中,连接臂本体17呈板状,板状的连接臂本体17沿竖直方向延伸,其前侧与后罩7连接,前侧或者后侧与支撑杆连接。
并且,连接臂本体17上形成有用于容纳导线(参照下文描述)的线槽20。由此,导线可以集中容置在线槽20内,以避免导线杂乱无章的分布,进而有利于后续的管理或者维护。具体而言,线槽20是由连接臂本体17的边缘向前侧延伸形成的围板和连接臂本体17共同围成的。
应做广义理解的是,导线可以为连接电机组件10和风扇的蓄电池的线缆,蓄电池通过导线为电机组件10提供电能,进而使得电机组件10能够有效工作。这里,蓄电池可以设置在底座组件2上,此时支撑杆可以为空心,导线可以从支撑杆内向上延伸以与电机组件10连接。由此,底座组件2的重量增加,进而使得底座组件2能够稳定的支撑风扇头。
进一步地,继续参照图3,线槽20盖设有电线装饰盖18。如此设置,电线装饰盖18封闭线槽20,以将导线锁闭在线槽20内,进而有利于避免导线暴露在外界环境中而遭到破坏,降低风扇遭到毁坏的风险,同时,有利于避免外露的导线影响风扇的整体视觉效果,风扇更美观。
图3所示的示例中,电线装饰盖18包括盖设在线槽20的盖板和围设在盖板的边缘的侧板,也即电线装饰盖18呈一侧开口的盒状结构,相比于板状结构,盒状结构的电线装饰盖18供导线容置的空间更大。
可选地,电线装饰盖18可以与连接臂本体17卡接配合。具体的,如图3所示,侧板插设在线槽20内且其外壁与连接臂本体17的围板的内壁紧密贴合。
可替代的,电线装饰盖18可以与后罩7螺接配合,此时的电线装饰盖18仅覆盖在线槽20上,而不与连接臂本体17连接。具体的,如图4所示,电线装饰盖18上设有螺纹孔44,后罩7上设有通孔43,通孔43的中心线与螺纹孔44的中心线共线,紧固螺钉穿过通孔43后与螺纹孔44配合,以使电线装饰盖18与后罩7连接。
当然,电线装饰盖18可以同时采用上述两种连接方式进行连接,也即,电线装饰盖18与连接臂本体17卡接的同时,还与后罩7螺接,使得 连接臂本体17也能够通过电线装饰盖18与后罩7连接。由此可知,电线装饰盖18通过可拆卸的方式与连接臂本体17进行连接,所以电线装饰盖18可以从连接臂本体17拆卸下来,线槽20能够打开,从而便于维护导线。
其中,连接臂本体17上还设有贯穿连接臂本体17的过线孔,过线孔与线槽20连通,用于供导线穿过。由此,连接蓄电池与电机组件10的导线可以由底座组件2穿设至支撑杆内,沿支撑杆向上延伸,再由过线孔贯穿到线槽20内,之后再与电机组件10连接。
结合图2和图3,连接臂本体17上设有铰接座,铰接座用于与支撑杆转动连接。由此,与连接臂6连接的风扇罩能够相对于底座组件2的支撑杆转动,则风扇组件(即风扇本体1)可转动地安装在支撑杆上。当铰接座的铰接轴线平行于水平面时,风扇组件可相对于底座组件2翻转一定角度,通过调整风扇组件的角度,风扇产生的气流可以向上、水平或者向下吹出,进而能够适应用户不同的需求。当铰接座的铰接轴线垂直于水平面时,风扇组件可相对于底座组件2在水平面转动一定的角度,从而扩大了送风区域,提高了用户的舒适度。
具体的,铰接座设置在连接臂本体17的底端。由此,与铰接座设置在连接臂本体17的顶端相比,当铰接轴线平行于水平面时,有利于降低风扇组件绕铰接轴线转动时与支撑杆发生干涉的风险。其中,铰接座可以往前方延伸,此时的铰接座设置在风扇头的下方,支撑杆位于连接臂6的前侧以与铰接座连接,具体的,支撑杆与板状的连接臂本体17的前侧连接;铰接座也可以往后方延伸,此时的支撑杆位于连接臂6的后侧以与铰接座连接,与上一示例相比,位于风扇前方的用户无法观察到铰接座,美观性好。
以铰接座往后方延伸为例进行说明,铰接座可以包括自连接臂本体17往后延伸的铰接壳体,铰接壳体形成有用于与支撑杆转动连接的铰接轴,风扇组件绕铰接轴转动。值得说明的是,铰接轴沿其轴线的方向上设有过线通道,过线孔设置在连接臂本体17与铰接壳体相对应的位置。由此,线槽20、过线孔、过线通道以及支撑杆的内部依次连通,形成供导线穿设的走线通道,进而使得导线隐藏在走线通道内,风扇的整体美观。
图2和图3所示的示例中,铰接壳体包括平行设置的第一铰接壳体和 第二铰接壳体,第一铰接壳体和第二铰接壳体形成有相对的第一铰接轴和第二铰接轴。由此,与只设置有一个铰接轴相比,铰接壳体与支撑杆的连接关系更稳定。在该示例中,第一铰接壳体和第二铰接壳体之间具有安装空间,支撑杆位于该安装空间内,其两侧分别与第一铰接轴和第二铰接轴铰接。
图2至图4中,对连接臂6和后罩7的具体连接关系进行详细说明。
首先,对连接臂6与后罩7通过卡接的方式进行连接的具体结构进行介绍。具体如图2和图3所示,连接臂本体17设有往前方延伸的插接头19,插接头19用于与设置在后罩7上的插槽16插接。由此,连接方式简单。其中,插接头19可以设置在连接臂本体17的底端和/或顶端,相应的,后罩7的下部和/或上部上设有插槽16,设置在连接臂本体17底端的插接头19与后罩7下部的插槽16插接,设置在连接臂本体17顶端的插接头19与后罩7上部的插槽16插接。当连接臂本体17的底端和顶端均设有插接头19时,由连接臂本体17和插接头19组成的连接臂6可以至少包围后罩7的一部分。
本实施例进一步的实现方式中,插接头19上还设置有防脱台21,防脱台21用于与插槽16的内侧壁连接。由此,有利于防止插接头19从插槽16内脱离出去,进一步有利于避免连接臂6与后罩7分离,使得连接臂6与后罩7稳定连接。另外,防脱台21的前侧壁形成为倾斜面,从而在连接臂6与后罩7装配时,便于将防脱台21卡入到插槽16内,安装方便。
其次,对连接臂6通过其他中间件与后罩7进行连接的具体结构进行介绍。如图3所示,连接臂本体17设有用于与风扇罩连接的安装台12,也即风扇罩安装在安装台12上。由此,实现了连接臂6与风扇罩相连。
当连接臂本体17只与后罩7的下部的部分连接时,安装台12可以设置在连接臂本体17的顶端;当连接臂本体17只与后罩7的上部的部分连接时,安装台12可以设置在连接臂本体17的底端;当由连接臂本体17和插接头19组成的连接臂6至少包围后罩7的一部分,此时的连接臂本体17横跨后罩7的上部分和下部分时,安装台12可以设置在连接臂本体17的中部。通过上述设置,使得安装台12尽可能的与后罩7的中间部分 连接,以尽可能的增大连接面积,连接关系可靠。
和插接头19与后罩7的连接方式类似,安装台12与后罩7也可以通过套接或者卡接的方式连接。一种可选的示例中,安装台12的前端面上设有卡槽,后罩7的背面上设有与卡槽卡合的卡块。另一种可选的示例中,如图2和图3所示,安装台12形成为圆形并且包括往前方凸出的侧壁,后罩7上形成有圆形安装孔,侧壁的至少一部分伸入圆形安装孔内并与后罩套接或者卡接,也即后罩7套装在安装台12的侧壁上。当然,可以理解的是,安装台12也可以替换为方形、三角形、矩形等规则形状,相应的,后罩7上形成的安装孔可以为方形、三角形、矩形等形状。
为了对后罩7进一步辅助固定,风扇罩内还设有锁定组件9,锁定组件9用于锁止后罩7,以阻止后罩7沿其轴线向前移动,进而使得后罩7稳定的安装在安装台12上。
一种示例中,如图9所示,锁定组件9包括设置在风扇罩内的锁定环14,锁定环14与安装台12可拆卸连接,锁定环14的外径大于圆形安装孔的内径。由此,锁定环14可以阻挡后罩7从前方脱离安装台12,同时,位于后罩7后方的连接臂本体17可以阻挡后罩从后方脱离安装台12,进而使得后罩7能够稳定的与连接臂6连接。需要清理后罩7时,将锁定环14从安装台12上拆卸下来,再向远离前罩8的一侧推动连接臂6,使得安装台12脱离后罩7的同时,防脱台21与插槽16的内壁脱离,从而可以分离风扇罩与连接臂6。
举例来说,安装台12的侧壁上可以形成有第一外螺纹13,锁定环14的内壁上形成有与第一外螺纹13配合的第一内螺纹,使得安装台12与锁定环14螺接,装卸时旋拧锁定环14即可。为了装卸时旋拧方便,锁定环14的外表面上还设有防滑部,有利于避免旋拧时出现打滑现象。其中,防滑部可以为网格纹,或者,如图9所示,防滑部为设置在锁定环14的外表面上的凸齿状结构或者条纹状结构。
另一种示例中,锁定组件9包括设置在风扇罩内的卡接环,安装台12上设有卡扣部,卡接环与卡扣部卡接配合,且卡接环的外径大于圆形安装孔的内径。由此,卡接环可以阻挡后罩7从前方脱离安装台12。具体的,卡扣部可以为设置在安装台12的侧壁的弹性凸起,相应的,卡接环的内 壁上设有与弹性凸起相配合的凹陷;或者,卡扣部为设置在安装台12侧壁的凹陷,相应的,卡接环的内壁上设有与凹陷相配合的弹性凸起。
为了进一步提高后罩7的稳定性,锁定组件9可以为多个,也即锁定环14或者卡接环可以为多个,多个锁定环14或者多个卡接环由前向后依次与安装台12连接。当然,在一些示例中,锁定环14和卡接环也可以组合使用,此时,至少有一个锁定环14与安装台12螺接,并且至少有一个卡接环与安装台12卡接。
下面参考附图详细的描述风扇头的结构和功能。
如前文所述,参照图5,风扇头包括风扇罩及设置在风扇罩内的扇叶组件11和电机组件10,电机组件10给扇叶组件11提供动力,以驱动扇叶组件11转动。其中,电机组件10包括可分离的电机定子32和电机转子33,电机定子32可拆卸地固定在安装台12上,电机转子33可相对电机定子32转动,电机转子33上设有电机轴,该电机轴与扇叶组件11传动连接,以驱动扇叶组件11转动。可选地,电机组件10可以为内转子电机,也即电机定子32套设在电机转子33外,或者,如图5所示,电机组件10为外转子电机,也即电机转子33套设在电机定子32外。
下面仅以电机组件10为外转子电机为例进行描述。可以理解的是,该电机转子33包括电机罩35和磁环36,电机罩35的内部具有空腔,电机定子32和磁环36均容置在空腔内,并且磁环36位于电机罩35和电机定子32之间。电机组件10通电后,磁环36产生磁场相互作用,使得电机转子33相对于电机定子32转动起来,进而驱动扇叶组件11转动。
如图3和图5所示,相对于风扇罩固定的安装台12设有往前凸出的安装柱31,安装柱31用于安装电机组件10。当电机组件10为内转子电机时,电机定子32可拆卸地固定在安装柱31上,也即安装柱31用于固定电机定子32;当电机组件10为外转子电机时,电机定子32或者电机罩35可拆卸地固定在安装柱31上,也即安装柱31用于固定电机定子32或者电机罩35。由此,设置在连接臂本体17的安装台12与风扇罩一起组成风扇头的一部分,且电机组件10可拆卸的装配在安装台12的安装柱31上,实现了电机组件10的拆装。拆卸时,电机组件10可直接从安装台12上拆卸下来,进而使得整个风扇头能够从底座组件2上拆卸下来,便于对 整个风扇头进行清理。
其中,电机定子31卡套在安装柱31上。示意性地,电机定子31朝向安装台12的一端设有套装槽,安装柱31穿设在套装槽内。较佳地,电机定子32呈环状,环状的电机定子32卡套在安装柱31上。由此,环状的电机定子32为电机转子33与安装柱31的连接提供机会,进而提高了电机组件10与安装台12连接的可靠性。
参照图7,电机转子33上设置有转轴34,安装柱31沿其轴线方向设有用于与转轴34转动装配的安装孔。换句话说,转轴34经环状的电机定子32穿过并插设在安装孔内以与安装柱31可转动的连接。由此,电机转子33与安装柱31连接且可相对于安装柱31转动,进而提高了电机组件10与安装台12连接的可靠性。具体的,转轴34紧固设置在电机罩35的空腔内,并沿磁环36的轴线方向往安装柱31方向延伸,以有效的插装至安装孔内。
本实施例对转轴34与电机罩35的连接方式不做限制,例如,转轴34与电机罩35通过铸造、锻造或者注塑等一体加工工艺形成为一体结构。由此,省去了装配电机罩35与转轴34的工序,提高了组装效率。而且,在不提高成本的前提下,可以提高电机转子33的强度。容易理解的是,除了一体加工成型之外,转轴34与电机罩35还可以通过焊接、粘接或者卡接的方式连接。
如图3和图7所示,安装孔内还安装有环套,环套套设在转轴34上,转轴34可相对于环套转动。由此,环套支承转轴34转动,有利于降低转轴34转动时与安装孔的孔壁之间产生的摩擦。进一步地,转轴34的第一端(也即图7中的前端)设有卡环38,环套位于卡环38和转轴34的第二端(也即图7中的后端)之间,卡环38的外径大于环套的内径。由此,卡环38可以阻止转轴34脱离环套,使得环套能够始终套设在转轴34上起到支承转动的作用。具体的,环套的材质不限于金属材质,例如环套为铜套37、铝合金环套,环套的材质还可以为陶瓷或者为塑料。
较佳的,安装柱31设置在安装台12的中心。这样设置,与安装柱31可拆卸连接的电机组件10相对固定在安装台12的中心位置,以避免电机组件10偏离安装台12的中心设置。
可选的,安装台12的中心可以与风扇罩的中心位于同一高度。由此,安装台12的中心以及与安装台12连接的电机组件10的中心均与风扇罩的中心平齐,则设置在风扇罩内的电机组件10不会沿上下方向偏离风扇罩的中心。
可选的,安装台12的中心位于驱动扇叶组件11转动的电机轴的轴线的延伸线上。也就是说,电机组件10的电机轴位于安装台12的中心,则与电机轴传动连接的扇叶组件11的中心也位于安装台12的中心,使得安装台12、电机组件10以及扇叶组件11的中心和风扇罩的中心在竖直平面上的投影均重合,也即各部件的中心重合而不偏离中心设置,进一步提高了风扇的美观性。
下面参考附图详细的描述扇叶组件11的结构和功能。
扇叶组件11设置在风扇罩内并与电机转子33传动连接,电机转子33驱动扇叶组件11旋转,使得空气形成气流,驱动气流从风扇罩内吹出,以降低周围空气温度。具体的,如图5所示,扇叶组件11包括若干扇叶22和设置在扇叶22中部的安装头24,若干个扇叶22呈放射状设置在安装头24的周向,安装头24与电机转子33可拆装的连接,使得扇叶组件11可拆装的固定在电机转子33上。由于前罩8和后罩7可拆卸的连接在一起,前罩8被拆离后,扇叶组件11能够从电机组件10上拆卸下来并能够从风扇罩内取出,进而便于清理扇叶22上的灰尘,有利于避免扇叶22上的灰尘被气流吹出而导致外界的环境受影响。
容易理解的是,安装头24可以通过设置在电机转子33的前端面的中间件与电机转子33可拆卸的连接。较佳地,参照图5和图8,安装头24套接在电机转子33的外侧以与电机转子33可拆卸的连接。具体来说,安装头24朝向后罩7的一侧设有第二安装槽25,电机罩35容置在第二安装槽25内。由此,相较于安装头24安装在电机转子33的前端面而言,整个电机转子33对扇叶组件11提供了支承,连接关系可靠。并且,由于电机罩35容置在第二安装槽25内,所以有利于避免电机组件10在风扇罩内占据过大的容置空间(参照下文描述)。
较佳的,电机转子33与扇叶组件11通过安装组件23螺纹配合。由此,连接关系可靠,且连接方式简单。当然,除了螺接之外,电机转子33 与扇叶组件11还可以通过卡接等方式连接,此处对电机转子33与扇叶组件11的其他连接方式不再赘述。
本实施例描述了扇叶组件11与电机转子33的一种螺纹配合的示例,在本示例中,安装组件23包括设置在电机转子33的卡接台27和设置在扇叶组件11的安装部26,其中,卡接台27为设置在电机转子33上以与扇叶组件11螺纹配合的弧形齿条,弧形齿条的齿宽沿着电机转子33的旋转轴线方向延伸;相应的,安装部26为设置在安装头24的第二安装槽25的槽壁上以与电机转子33螺纹配合的齿形部,齿形部的齿宽也沿着电机转子33的旋转轴线方向延伸,齿形部与弧形齿条配合以实现扇叶组件11与电机转子33螺纹配合。这里,第二安装槽25的槽壁可以理解为侧壁、也可以理解为槽底。
例如,弧形齿条可以设置在电机转子33的电机罩35的外侧面上,此时的齿形部设置在第二安装槽25的侧壁上,以与弧形齿条螺纹配合。
再例如,参照图5、图6和图8,弧形齿条可以设置在电机转子33的电机罩35的前表面上,此时的齿形部设置在第二安装槽25的槽底上,以与弧形齿条螺纹配合。
值得说明的是,齿形部可以由凸出设置在第二安装槽25的槽壁上的内齿轮的齿构成,该内齿轮与弧形齿条相配合,也可以由凹陷设置在第二安装槽25的槽壁的齿轮槽的齿构成,该齿轮槽与弧形齿条相配合。
通过设置弧形齿条和与之配合的齿形部,从而实现了电机组件10与扇叶组件11的螺纹配合,使得扇叶组件11能够随电机转子33的转动而同步旋转。
进一步地,弧形齿条可以为多个。通过设置多个弧形齿条,加强了电机转子33与电机组件10之间的连接可靠性。图6所示的示例中,电机转子33的旋转轴线两侧设有关于旋转轴线对称的两个弧形齿条。
需要指出的是,电机转子33与扇叶组件11的螺纹配合被配置成在电机转子33带动扇叶组件11转动时,电机转子33与扇叶组件11往旋紧的方向转动。由此,电机转子33运行时,扇叶组件11不仅能够随之转动,而且两者逐渐旋紧,以避免扇叶组件11往旋松的方向转动而导致两者松脱。
在上述实施例的基础上,继续参照图6和图8,电机转子33上设有插接柱28,第二安装槽25的槽底设有与插接柱28插接的插接座,使得电机转子33与扇叶组件11在螺纹配合的基础上还通过插接的方式进行连接,以使扇叶组件11能够固定安装在电机组件10上。需要指出的是,插接过程中,弧形齿条与齿形部可以以任意角度插接配合在一起,有利于避免扇叶22装配时刻意寻找安装角度或者安装位置而导致装卸不便的问题,提升了扇叶22与电机组件之间装配的便捷性。
具体的,插接柱28设置在电机转子33的前表面上并往电机转子33的前方延伸,插接座上设有插接孔30,插接孔30与插接柱28对准,使得插接柱28插接在插接孔30内。
本实施例优选的示例为,插接柱28设置在电机转子33的前表面的中心位置,相应的,插接座设置在第二安装槽25的槽底的中心位置。如此设置,扇叶组件11不会偏离电机转子33的中心设置,使得美观性较好的同时,有利于避免运行时偏心导致的震动。进一步地,插接柱28上设有环槽,插接柱28上套设有阻尼圈29,阻尼圈29位于环槽内。由此,阻尼圈29与插接孔30的内壁抵接,以防止插接柱28从插接孔30内脱离,进而有利于避免电机转子33与扇叶组件11分离。
另外,弧形齿条、插接柱28以及电机罩35可以通过铸造、锻造或者塑造等一体加工工艺形成为一体结构。由此,省去了装配电机罩35与弧形齿条及插接柱28的工序,提高了组装效率。而且,在不提高成本的前提下,可以提高电机转子33的强度。当然,弧形齿条和插接柱28也可以通过焊接或者粘接等方式连接在电机罩35上。
参照图5,本实施例提供的风扇的一种示例性的拆卸过程为:
先分离前罩8和后罩7,使得前罩8从后罩7上拆下来;
向远离后罩7的一侧移动扇叶组件11,使得插接座从插接柱28上脱出,此时的阻尼圈29也从插接孔30内脱出,从而将扇叶组件11从电机组件10上拆卸下来;
再旋拧锁定环14,使得锁定环14的第一内螺纹与安装台12的侧壁的第一外螺纹13脱离配合,则锁定环14脱离安装台12;
向后侧也即远离前罩8的一侧推动连接臂6,电机组件10的电机定子 32脱离与安装柱31的卡合,则电机组件10从安装台12上拆卸下来并向前移动电机组件10,与此同时,防脱台21与插槽16的内壁脱离,插接头19从插槽16内脱出,继而成功将后罩7、电机组件10和连接臂6分离,从而完成了风扇头的拆卸。
基于上述,前罩8、后罩7、扇叶组件11和电机组件10均可以单独拆卸下来,因此这些部件均能够单独进行清理,清理方便。
实施例2:
结合图9,与实施例1不同的是,实施例2描述了扇叶组件11与电机组件10的另一种螺纹配合的示例。在本示例中,安装组件23包括设置在电机转子33的卡接台27和设置在扇叶组件11的安装部26,其中,卡接台27为设置在电机转子33上以与扇叶组件11螺纹配合的弧形齿条,弧形齿条的齿宽沿着电机转子33的旋转轴线方向延伸;相应的,安装头24的槽底设有安装缺口,安装缺口为通孔,安装部26为设置在安装缺口的侧壁上以与电机转子33螺纹配合的齿形部,齿形部的齿宽也沿着电机转子33的旋转轴线方向延伸,也即安装缺口呈齿形状,齿形状的安装缺口与弧形齿条配合以实现扇叶组件11与电机转子33螺纹配合。
具体的,扇叶组件11的安装头24还包括安装头本体以及固定盖40,安装缺口设置在安装头本体的前端,固定盖40盖设在安装缺口处、并与安装头本体围成第二安装槽,安装缺口的侧壁设有与弧形齿条螺纹配合的齿形。
另外,需要说明的是,弧形齿条的数量、与电机罩35的安装方式以及与齿形部配合的方向等均与实施例1类似,在此不再一一进行赘述。
继续参照图9,电机转子33上设有螺纹柱39,固定盖40与螺纹柱39螺纹连接。由此,使得电机转子33与扇叶组件11在螺纹配合的基础上还通过螺纹柱39与固定盖40的配合进行连接,以使扇叶组件11能够固定安装在电机组件10上。具体的,螺纹柱39设置在电机转子33的前表面上,固定盖40设置在安装头24外,固定盖40朝向电机组件10的一侧设有第三安装槽,螺纹柱39的外表面上设有第三外螺纹,第三安装槽的侧壁设有与第三外螺纹配合的第三内螺纹。
较佳地,第三外螺纹与第三内螺纹的螺纹配合被配置成在电机转子33带动扇叶组件11转动时,电机转子33与扇叶组件11往旋紧的方向转动。由此,电机转子33转动进而带动扇叶组件11转动的同时会带动扇叶组件11旋拧,使得电机转子33与扇叶组件11逐渐旋紧,以避免扇叶组件11往旋松的方向转动而导致两者松脱。
固定盖40还可以与安装头24连接,以进一步提高固定盖40的安装稳定性。示意性地,固定盖40可以通过焊接、卡接或者螺接的方式与安装头24连接,以封堵安装缺口。
本实施例优选的示例为,螺纹柱39设置在电机转子33的前表面的中心位置,相应的,第三安装槽设置在第二安装槽25的槽底的中心位置。如此设置,扇叶组件11不会偏离电机转子33的中心设置,使得美观性较好的同时,有利于避免运行时偏心导致的震动。当然,作为可替换的实现方式,螺纹柱39也可以替换为卡接柱,卡接柱与固定盖40卡接连接,从而实现扇叶组件11的固定装配。
参照图9,本实施例提供的风扇的另一种示例性的拆卸过程为:
先分离前罩8和后罩7,使得前罩8从后罩7上拆下来;
将扇叶组件11往旋松的方向旋拧,使得扇叶组件11的固定盖40与电机转子33的螺纹柱39分离,从而将扇叶组件11从电机组件上拆卸下来;
再旋拧锁定环14,使得锁定环14的第一内螺纹与安装台12的侧壁的第一外螺纹脱离配合,则锁定环14脱离安装台12;
向后侧也即远离前罩8的一侧推动连接臂6,电机组件10的电机定子32脱离与安装柱31的卡合,则电机组件10从安装台12上拆卸下来并向前移动电机组件10,与此同时,防脱台21与插槽16的内壁脱离,插接头19从插槽16内脱出,继而成功将后罩7、电机组件10和连接臂6分离,从而完成了风扇头的拆卸。
实施例3:
参照图10,与实施例1和实施例2不同的是,实施例3描述了扇叶组件11与电机组件10的再一种螺纹配合的示例。在本示例中,扇叶组件11 包括安装头24和设置在扇叶22的周向的若干扇叶22,安装头24朝向后罩7的一侧设有第二安装槽25,安装组件23包括设置在第二安装槽25的内壁的第二内螺纹41和设置在电机罩35的外壁的第二外螺纹42,第二内螺纹41与第二外螺纹42相配合,以使扇叶组件11与电机转子33实现螺纹配合。
较佳地,第二外螺纹42与第二内螺纹41的螺纹配合被配置成在电机转子33带动扇叶组件11转动时,电机转子33与扇叶组件11往旋紧的方向转动。由此,电机转子33转动进而带动扇叶组件11转动的同时会带动扇叶组件11旋拧,使得电机转子33与扇叶组件11逐渐旋紧,以避免扇叶组件11往旋松的方向转动而导致两者松脱。
参照图10,本实施例提供的风扇的再一种示例性的拆卸过程为:
先分离前罩8和后罩7,使得前罩8从后罩7上拆下来;
将扇叶组件11往旋松的方向旋拧,使得扇叶组件11的第二内螺纹41与电机转子33的第二外螺纹42分离,从而将扇叶组件11从电机组件10上拆卸下来;
再旋拧锁定环14,使得锁定环14的第一内螺纹与安装台12的侧壁的第一外螺纹脱离配合,则锁定环14脱离安装台12;
向后侧也即远离前罩8的一侧推动连接臂6,电机组件10的电机定子32脱离与安装柱31的卡合,则电机组件10从安装台12上拆卸下来并向前移动电机组件10,与此同时,防脱台21与插槽16的内壁脱离,插接头19从插槽16内脱出,继而成功将后罩7、电机组件10和连接臂6分离,从而完成了风扇头的拆卸。
实施例4:
继续参照图4、图5、图9和图10,在前述任一实施例的基础上,风扇罩包括前罩8和后罩7,前罩8和后罩7相连以共同围成容置空间,容置空间用于供电机组件10和扇叶组件11安装,从而避免扇叶组件11暴露在外以致于用户误触扇叶22而受伤。
前罩8和后罩7的形状不限于圆柱状,前罩8和后罩7沿其轴线方向的横截面也可以为矩形、方形、椭圆形、菱形等其他规则或不规则的形 状,本实施例对此不做限制。较佳的,如图5所示,前罩8和后罩7均呈圆柱状,美观性较好,符合人们的审美习惯,也利于收纳和运输。
举例而言,当前罩8和后罩7扣合形成的圆柱体与圆柱体形状的底盘5具有基本相同的直径时,可以进一步提高存储和运输的便捷性。当然,在具体实现的过程中,风扇罩可以叠置在底盘5上。由此,在风扇罩与底盘的直径相同的基础上,叠置在一起的风扇本体1能够占用更少的空间,便于运输。具体的,后罩7的后表面和底盘5的顶面可以设置相互配合的台阶面,以便使风扇主体1收纳叠置在底盘5上时,提高二者的贴合度,避免视觉上出现凹凸不平的感觉。
继续参照图4、图5、图9和图10,前罩8的后端与后罩7的前端具有相同的形状,使得前罩8和后罩7能够相互连接。可以理解的是,前罩8和后罩7相互连接应当作广义理解,也即可以理解为以下情形:
一种情形为前罩8与后罩7对接,前罩8的后端面与后罩7的前端面相抵,且整个前罩8完全位于后罩7外,整个后罩7也完全位于前罩8外。在该示例中,前罩8的后端面可以为平面,相应的,后罩7的前端面也为平面;或者,前罩8的后端面也可以为曲面(例如:台阶面),相应的,后罩7的前端面为与前罩8的后端面相配合的曲面(例如:台阶面)。
当前罩8的后端面与后罩7的前端面为曲面时,前罩8和后罩7的接合处平滑过渡。由此,前罩8和后罩7的加工方便,且接合处能够紧密连接在一起,以确保前罩8和后罩7连接的可靠性。
另一种情形中,参照图1、图9和图10,前罩8的后端面容纳于后罩7的前端开口内,此时的前罩8的侧壁的外表面与后罩7的侧壁的内表面接触。与上一情形相比,本实施的前罩8的至少部分隐藏在后罩7内,前罩8和后罩7的连接处也隐藏在后罩7的内部,美观性较好。
再一种情形中,后罩7的前端面容纳于前罩8的后端开口内,此时的前罩8的侧壁的内表面与后罩7的侧壁的外表面接触。与第一种情形相比,本实施的后罩7的至少部分隐藏在前罩8内,前罩8和后罩7的连接处也隐藏在前罩8的内部,美观性较好。
在上述实施例的基础上,为了便于拆装,前罩8和后罩7可拆卸式装配。由此,前罩8和后罩7能够分离,前罩8可以从后罩7拆卸下来,以 便于清理前罩8上的灰尘,有利于避免前罩8上的灰尘被气流吹出而导致外界的环境受影响。结合前述内容可知,后罩7可以与电机组件10及连接臂6分离,也即后罩7也可以单独拆卸下来,以便于清理后罩7上的灰尘,清洗方便。
实现前罩8和后罩7可拆卸连接的方式可以为螺接连接,也可以为卡接连接。本实施例较佳的方式为前罩8和后罩7卡接配合,这样,前罩8和后罩7无需通过螺栓、螺钉等部件进行连接,继而有利于避免螺栓或螺钉等部件外露而影响风扇整体的视觉效果。
示意性地,参照图5、图9和图10,当前罩8和后罩7通过另一种情形中的安装方式相连,也即前罩8的后端面容纳于后罩7的前端开口内时,前罩8的侧壁的外表面上可以设有卡接凹槽81,后罩7的侧壁的内表面上设有与卡接凹槽81配合的卡接凸块71。
可选的,卡接凹槽81可以包括相连通的过槽和卡止槽,过槽靠近前罩8的后端面的一侧具有相连通的缺口,缺口和过槽被配置成能够容纳卡接凸块71,则卡接凸块71能够通过缺口容置到过槽内;卡止槽沿前罩8的周向延伸,且与卡接凸块71卡接配合。换句话说,卡接凹槽81大体上呈“L”形,“L”形的卡接凹槽81的短边上的槽边位于前罩8的后端面的边缘。
如图11和图12所示,过槽还可以倾斜于卡止槽设置,卡止槽仍沿前罩8的周向延伸,也即过槽的中轴线与卡止槽的中轴线不相互垂直,由此,卡接凸块71容易沿过槽倾斜的槽壁滑入至卡止槽内。进一步地,如图13和图14所示,过槽与卡止槽的交界位置还可以设置为圆弧段,从而进一步提高了卡接凸块71由过槽滑入卡止槽的顺畅性。
可以理解的是,当前罩8和后罩7通过再一种情形中的安装方式相连,也即后罩7的前端面容纳于前罩8的后端开口内时,后罩7的侧壁的外表面上设有卡接凹槽,前罩8的侧壁的外表面上设有与卡接凹槽配合的卡接凸块。
参照图5,本实施例提供的风扇罩的一种示例性的安装过程为:
先将前罩8的卡接凹槽81的缺口对准卡接凸块71,也即将“L”形的卡接凹槽81的短边上的槽边与卡接凸块71对齐;
向后方移动前罩8,使得卡接凸块71通过缺口并容置到过槽内;
再转动前罩8,使得卡接凸块71由过槽滑入到卡止槽内并与卡止槽卡紧,从而实现前罩8与后罩7的装配。
可以理解的是,风扇罩的拆卸过程与安装过程相逆,在此不再进行赘述。
实施例5:
在前述任一实施例的基础上,为了实现送风,构成风扇罩的前罩8和后罩7上均设有栅格,位于风扇罩内的扇叶组件11转动以形成气流,气流通过栅格吹至用户身上,使用户感到凉爽。
前罩8上具有出风栅格,气流在扇叶22的驱动作用下从出风栅格流出。其中,前罩8的中心位置设有固定板,出风栅格连接于固定板并呈放射状布置,也就是说,出风栅格的一端与固定板连接,另一端与前罩8的外边缘连接。示例性地,参照图1和图4,出风栅格可以呈直线放射状;或者,参照图15,出风栅格也可以呈弧线放射状;当然,出风栅格还可以呈曲线放射状。
下面参考附图详细的描述后罩7的结构。
继续参照图2,后罩7的背面包括栅格部分,栅格部分用于供气流流通。由此,外界环境中的空气在扇叶22的驱动作用下形成气流,气流能够从后罩7的栅格部分进入到风扇罩内,以被扇叶22吹送出去。
作为一种可选的方式,如图2所示,栅格部分可以呈放射状布置,具体的是指栅格部分的一端与后罩7的圆形安装孔的孔壁连接,另一端与后罩7的外边缘连接。和前罩8的出风栅格类似的,栅格部分可以呈直线放射状、弧线放射状或者曲线放射状。
作为一种可替换的方式,如图16所示,栅格部分包括若干横向进风栅格部分以及若干纵向进风栅格部分,如此,可以优化流经风扇的气流的分布,从而提高风扇的制冷效果,与放射状的栅格相比,风力能够提高。
当横向进风栅格部分和纵向进风栅格部分均为一个时,横向进风栅格部分和纵向进风栅格部分可以沿后罩7的中心对称设置。当横向进风栅格部分和纵向进风栅格部分为两个及以上时,可选的,横向进风栅格部分和 纵向进风栅格部分可以交替设置。这样设置,与呈放射状的栅格部分相比,与纵向进风栅格部分相邻的横向进风栅格部分对该纵向进风栅格部分在一定程度上能够起到支撑作用,与横向进风栅格部分相邻的纵向进风栅格部分对该横向进风栅格部分在一定程度上能够起到支撑作用,使得后罩7具有较高的结构稳定性。
继续参照图16,当横向进风栅格部分和纵向进风栅格部分均为两个时,进一步地,两个横向进风栅格部分布置在矩形的一条对角线上,两个纵向进风栅格部分布置在同一个矩形的另一条对角线上。
结合实施例1中描述的连接臂6的相关结构,继续参照图2,在本公开的一些实施例中,除了栅格部分,后罩7的背面还可以设有第一安装槽15,第一安装槽15用于供连接臂6的一部分安装。由此,连接臂6的至少部分容置在第一安装槽15内,以减少连接臂6外露的部分,美观性较好。
其中,第一安装槽15可以由后罩7向前方形成的凹陷构成,换句话说,第一安装槽15相对于栅格部分往前方凹陷;第一安装槽15也可以由向后方凸出设置在后罩7上的凸起和后罩7共同围成,换句话说,第一安装槽15相对于栅格部分往后方凹陷。本实施例较佳的实现方式为第一安装槽15相对于栅格部分往前方凹陷,这样设置,有利于避免连接臂6凸出于后罩7,提高了美观性。
本实施例对第一安装槽15的深度不做限制,较佳的,第一安装槽15的深度被配置成使得容置在其内部的连接臂本体17的后壁与后罩7的背面平齐,则连接臂本体17可以看成是风扇罩的一部分,风扇罩的整体视觉效果好,美观性好。
具体的,由前述内容可知,连接臂6包括连接臂本体17,连接臂本体17用于连接风扇头和底座组件2,也就是说,第一安装槽15可以用于容纳连接臂本体17。可理解的是,第一安装槽15的形状与连接臂本体17的形状相适配。
当连接臂本体17设有线槽20时,第一安装槽15的前表面被封闭,即线槽20被封闭,以遮蔽穿设在线槽20内的导线。由此,有利于避免容置在线槽20内的导线伸入至风扇罩内而导致缠绕在扇叶22或者电机组件 10上。具体的,后罩7上形成有板体,板体与与后罩7的背面共同围成第一安装槽15。
进一步地,当线槽20盖设有电线装饰盖18时,电线装饰盖18也容纳在第一安装槽15内。需要说明的是,当电线装饰盖18与后罩7螺接时,电线装饰盖18上设有螺纹孔44,后罩7上尤其是第一安装槽15的槽底壁上设有通孔43,通孔43的中心线与螺纹孔44的中心线共线,使得紧固螺钉穿过通孔43后与螺纹孔44配合。
示意性地,第一安装槽15可以设置在后罩7的上部和/或下部上。当后罩7的上部和下部均设有第一安装槽15时,连接臂本体17同时容置在上部和下部的第一安装槽15内,此时的连接臂本体17横跨后罩7的上部分和下部分。图2所示的示例中,第一安装槽15仅位于后罩7的下半部分内,则连接臂本体17对后罩7的下半部分进行支撑。
继续参照图2,第一安装槽15的顶端延伸至后罩7的中心,则容置在第一安装槽15内的连接臂本体17能够对后罩7的中心起到支撑作用,支撑更稳定。需要说明的是,该配置尤其适用于风扇头的中心与后罩7的中心在竖直平面上的投影重合的情形,此时的连接臂6对风扇头的支撑稳定。还需指出的是,当连接臂本体17通过安装台12与后罩7连接时,第一安装槽15的顶端延伸至后罩7的中心,并与后罩7上用于固定安装台12的圆形安装孔连通。而第一安装槽15的底端延伸至后罩7的底部边缘,这样,给连接臂本体17的底端延伸至后罩7外以对后罩7的侧壁进行支撑提供了机会。
在实施例1描述的一实施例中,连接臂本体17设有往前方延伸的插接头19,插接头19用于与设置在后罩7上的插槽16插接。相应的,在本实施例中,第一安装槽15的槽壁上设有用于供插接头19插接的插槽16,以在连接臂本体17容置在第一安装槽15内的同时,与连接臂本体17连接的插接头19插设在插槽16内。
可选的,插槽16可以设置在后罩7的边缘位置。由此,与插槽16设置在后罩7的中部位置相比,插入到该插槽16内的插接头19位于后罩7内,且也位于后罩7的边缘,进而有利于避免插入后罩7的插接头19与安装在风扇罩内的其他部件发生干涉。
可选的,如图2所示,当第一安装槽15的底端延伸至后罩7的底部边缘时,插槽16也可以设置在后罩7的侧壁上,此时的插接头19插设在后罩7的侧壁上,则插接头19与后罩7的侧壁可以组成后罩7的一部分。进一步地,插槽16的后侧壁与后罩7的背面之间具有间距。
实施例6:
在前述实施例中,支撑杆的底端与底座组件2连接,支撑杆的顶端与风扇组件可转动连接,支撑杆对风扇组件起到了支撑作用,并且,风扇组件能够相对于底座组件2的支撑杆转动,通过转动风扇组件来调整送风角度或者扩大送风区域。实施例1中给出了一种示例,连接臂本体17上设有铰接座,铰接座与支撑杆转动连接。相应的,支撑杆的顶端设有安装云台3,安装云台3与铰接座铰接。
底座组件2包括底盘5,底盘5的底面为平面,底盘5用于放置在地面、工作台等平面上。底盘5不限于为圆柱状,底盘5的横截面也可以为矩形、方形、椭圆形、菱形等其他规则或不规则的形状,本实施例对此不做限制。
参照图1,本实施例中,支撑杆为伸缩杆4。使用时,通过驱动伸缩杆4移动,可以改变伸缩杆4的长度,进而可以改变安装在支撑杆上的风扇组件的高度,从而可以改变吹出的风的高度,以满足用户不同的需求,实用性高。示例性地,伸缩杆4包括第一套管和套设在第一套管外的第二套管,第一套管可以沿第二套管的内部滑动。其中,第一套管伸出至第二套管外的一端与连接臂6连接,第二套杆远离第一套管的一端与底座组件2连接。
支撑杆的底端与底座组件2也可转动的连接,也即支撑杆可转动的安装在底座组件2的底盘5上,并且风扇上形成有容纳槽,支撑杆转动至水平状态时能够收纳于该容纳槽内,以使风扇罩和底盘5叠置在一起。其中,容纳槽可以形成在底座组件2的底盘5上,也可以形成在后罩7上,或者由底盘5和后罩7共同形成。
通过上述设置,支撑杆可以收纳在容纳槽内,风扇罩和底盘5叠置在一起,使得整个风扇在非使用状态时占据的空间较小,进而便于运输和日 常收纳。而且,可以避免支撑杆暴露在外界,不仅使得非使用状态的风扇的美观性较好,还有利于避免支撑杆受到外界的冲击力而损坏。另外,由于支撑杆位于风扇组件的后方,所以支撑杆收纳在容纳槽后,前罩8朝向风扇的外部。
举例来说,底盘5的顶面形成有第一半槽,后罩7的背面上形成有第二半槽,当风扇罩和底盘5叠置在一起时,第一半槽和第二半槽相连通,以共同构成容纳槽。
再举例,容纳槽位于底盘5上。与上一示例相比,有利于避免在后罩7上开设槽而导致后罩7的强度过低。值得说明的是,在该示例中,容纳槽的两端分别延伸至底盘5相对的两个边缘处。由此,容纳槽的尺寸尽可能的大,以便于容纳支撑杆,使得支撑杆能够顺畅的收纳在容纳槽内。
需要说明的是,当支撑杆为伸缩杆4时,容纳槽可以与伸出至最长的伸缩杆4匹配,则伸出至任意长度的伸缩杆4均可以收纳至容纳槽内,收纳方便;也可以与收缩至最短的伸缩杆4匹配,则容纳槽的尺寸小,进而有利于避免在后罩7和/或底盘5上开设过大的槽而导致其强度降低,当需要收纳风扇时,滑动伸缩杆4使其收缩至最短,然后再转动伸缩杆4,以使得伸缩杆4容置到容纳槽内,风扇罩和底盘5叠置在一起。
支撑杆与底座组件2可转动的连接,支撑杆相对于底座组件2转动并收纳至容纳槽内。具体的,支撑杆可以与容纳槽可转动的连接,也即支撑杆可转动的安装在容纳槽内。由此,支撑杆与容纳槽的转动连接部件位于容纳槽内,则整个支撑杆都能收纳至容纳槽内,美观性好。
支撑杆的底端与容纳槽可以通过转动轴可转动的连接,具体来说,容纳槽相对的两侧壁上均设有连接孔,两个连接孔相对设置,转动轴的一端可转动的安装在一个连接孔内,转动轴的另一端可转动的安装在另一个连接孔内;支撑杆的底端安装有连接套,连接套容置在容纳槽内,并且连接套背离支撑杆的一端套设在转动轴上,则支撑杆可绕转动轴转动。
其中,支撑杆的底端可以位于容纳槽的任一位置,也即支撑杆可以与容纳槽的任一位置转动连接,只要支撑杆能够转动并收纳至容纳槽即可。例如,支撑杆的底端可以位于容纳槽的中部,也可以靠近容纳槽的两个端部。
本实施例优选的实现方式为,支撑杆的底端位于容纳槽的其中一个端部,则转动后支撑杆的顶端可以位于容纳槽的另一个端部,整个支撑杆正好安置在容纳槽内。由此,与支撑杆的底端位于容纳槽的中部相比,本实施例中的支撑杆收纳至容纳槽后能够占满容纳槽,使得容纳槽的空间利用率高。
在上述实施例的基础上,风扇还包括锁紧机构,锁紧机构能够将支撑杆与底座组件2的底盘5锁紧,以使支撑杆不能够相对于底盘5转动。并且,锁紧机构还能够将支撑杆与底盘5解锁,以使支撑杆能够相对于底盘5转动。
当风扇不工作时,支撑杆收纳在容纳槽内;当需要运行风扇以降低外界环境的温度时,解锁锁紧机构,使得支撑杆能够相对于底盘5转动,再驱动支撑杆转动至竖立状态以支撑风扇组件,此时的风扇组件由叠置状态切换为工作状态,以使风扇正常工作;之后,利用锁紧机构锁紧支撑杆,以免风扇在工作状态时支撑杆转动而导致风扇组件运动,从而有利于避免出风受影响。
其中,锁紧机构可以包括套设在支撑杆外的外套筒,外套筒能够锁紧支撑杆以阻止支撑杆转动,且外套筒能够解除对支撑杆的锁定,以使支撑杆能够转动。
具体的,外套筒可以通过相对于伸缩杆4上下移动来锁紧或者解锁支撑杆和底盘5。由此,仅需要上下移动外套筒即可切换支撑杆的锁紧状态,执行锁紧支撑杆和解锁支撑杆的动作简单,方便调节。其中,实现外套筒相对于支撑杆上下移动的具体实现方式可以为外套筒与支撑杆滑动连接,则外套筒可以相对于支撑杆上下滑动,以锁紧或者解锁支撑杆;或者,外套筒与支撑杆螺纹连接,则外套筒可以相对于支撑杆旋转以实现上下移动,进而实现锁紧或者解锁支撑杆。
在这一实施例的基础上,支撑杆还包括与底盘5转动连接的内套筒,内套筒与外套筒螺纹连接。

优选地,如图1-7所示,插接头19上靠近插槽16一侧凸出设置有防脱台21,该防脱台21用于与插槽16的内侧壁抵接,从而有效防止后罩7脱离插接头19。电线装饰盖18通过经过螺钉与连接臂本体17固定装配。防脱台21上靠近前罩8一侧的侧壁为倾斜面,从而方便防脱凸块卡入插槽16内,保证了连接臂6与后罩7之间装配的便捷性。

本实施例的工作原理大致如下述:在拆卸风扇主体时,先通过转动前罩8,使得卡接凸块71脱离卡接凹槽81,并将前罩8从后罩7上拆下;然后,向远离后罩7一侧抽动扇叶22,使得阻尼圈29与插接孔30的侧壁脱离抵接状态,从而将扇叶22从电机组件10上拆下;再转动锁定环14,使得锁紧环14与安装台12脱离,然后向远离前罩8一侧推动连接臂6,使得安装台12脱离后罩7,与此同时,防脱台21与插槽16的内壁脱离,插接头19从插槽16内脱离,从而将风扇后罩7、电机组件10和连接臂6分离,从而完成风扇主体的拆卸,这样设置的风扇主体具有拆卸方便、清洗方便,拆卸后安装方便、安装后稳定性高、牢固性好的优势。
实施例8:
