具体实施方式
为了便于本领域技术人员的理解，下面结合实施例及附图对本发明作进一步的说明，实施方式提及的内容并非对本发明的限定。
请参阅图1至图7所示，本发明的一种带有导风套的充气机，包括机壳1、装设在机壳1内的机芯2及驱动电机3，驱动电机3用于驱动机芯2对外界的物件(如气胎或气球等)进行充气，机壳1上设有进气孔(图中未示出)及与进气孔连通的出气孔(图中未示出)；还包括导风套7及散热风扇6，导风套7上设置有贯穿导风套7的导风孔11，机芯2、驱动电机3位于进气孔与出气孔之间，优选地，机芯2、驱动电机3位于进气孔与出气孔之间的连线上，驱动电机3包括本体4及转动设置在本体4中的轴体5，轴体5的两端分别突伸出本体4的左右两端，轴体5的一端突伸出本体4的一端以用于驱动机芯2运动，轴体5的另一端突伸出本体4的另一端并用于连接散热风扇6，导风套7设置有定位壳8及与定位壳8连接的导风圈9，定位壳8与导风圈9为一体式构造，定位壳8用于装设在机壳1上或/和驱动电机3上，导风圈9套设在散热风扇6 的外侧，导风圈9环绕散热风扇6设置。
在充气机的使用过程中，机芯2及驱动电机3为主要的发热单元，本发明的充气机经由增设导风套7，利用导风套7的定位壳8实现相对机壳1或/和驱动电机3的准确定位，如此，即可确保散热风扇6准确地位于导风套7的导风圈9中，使得转动的散热风扇6抽取机壳1的空气经由导风套7的导风孔11流动，提高流经机芯2及驱动电机3的风压及风速，增强充气机的散热性能；利用导风圈9防护散热风扇6，防止散热风扇6受到碰撞而损坏，延长散热风扇6的使用寿命。
所述定位壳8的横截面为矩形，导风圈9的横截面为圆形，定位壳8的孔径大于导风圈9的孔径，利用定位壳8的孔径与导风圈9的孔径的差值实现流动空气的流速差，实现流动空气风压的变化及风速的变化，提升散热风扇6对驱动电机3及机芯2的散热效果；定位壳8的外表面抵触在机壳1上，利用定位壳8的平板外表面抵触机壳1，使得定位壳8与机壳1稳固地贴合在一起，防止定位壳8相对机壳1转动。本实施例中，定位壳8的拐角处均设置有导脚斜板(图中未标号)，导脚斜板的数量为四个，四个导脚斜板围绕导风孔11的中心轴线呈环形阵列，经由增设导脚斜板，增强定位壳8的强度，防止定位壳8因受到机壳1的挤压而轻易变形，提升导风套7的使用性能。
所述定位壳8上设置有突伸入导风孔11内的多个限位臂12，多个限位臂12围绕导风套7的中心轴线设置，多个限位臂12位于散热风扇6的同一侧，限位臂12远离散热风扇6的一侧用于抵触在本体4上。在充气机的组装过程中，先将导风套7组合到驱动电机3的本体4上，直至本体4的一端抵触在限位臂12的一侧上，实现对本体4与导风套7之间组装位置准确限定，而后再将散热风扇6装入导风圈9内。
所述限位臂12上设置有挡突13，挡突13自限位臂12的自由端朝导风套7的中心轴线突设而成，多个限位臂12围绕本体4设置，多个限位臂12的挡突13围绕导风孔11的中线轴线设置，限位臂12的自由端用于抵触在本体4的外 表面上，防止驱动电机3沿导风套7的径向方向相对导风套7发生移动，挡突13用于抵触在本体4一端的端面上，实现对本体4与导风套7之间组装位置准确限定。优选地，导风套7设置有连接多个限位臂12的过渡臂(图中未示出)，利用过渡臂将多个限位臂连接在一起，相较于单个限位臂12的强度，避免因单个限位臂12因强度较低发生变形而影响导风套7与驱动电机3之间定位的准确性。
所述限位臂12上设置有定位槽14，定位槽14自限位臂12远离散热风扇6的一侧凹设而成，机壳1上设置有突伸入定位槽14内的定位部(图中未示出)。利用定位槽14的侧壁抵触定位部，有效避免机壳1与定位壳8之间发生相对移动。
所述定位壳8上设置有卡持槽15，卡持槽15自定位壳8远离导风圈9的一端凹设而成，机壳1上设置有突伸入卡持槽15内的卡持块(图中未示出)。本实施例中，机壳1经由上壳(图中未标号)与下壳(图中未标号)组合而成，当充气机组装完成后，卡持块突伸入卡持槽15内，利用卡持块辅助增强定位壳8的强度，当上壳与下壳抵触在定位壳8的外表面上之后，防止定位壳8自身的强度过度而被挤压变形。
所述带有导风套的充气机还包括固定圈16，固定圈16套设在驱动电机3的外侧，固定圈16固定在机壳1上，驱动电机3的外表面与机壳1的内表面之间具有过气间隙，散热风扇6驱动的流动空气流经驱动电机3与机壳1之间的过气间隙，进而带走机芯2与驱动电机3的热量，提升充气机的散热效果。
所述固定圈16上设置有两个凸耳17，两个凸耳17分别自固定圈16彼此远离的两侧朝彼此远离的方向突设而成，两个凸耳17分别固定在机壳1上，减少固定圈16与机壳1的接触面积；优选地，两个凸耳17上均设置有卡持盲槽18，固定圈16采用塑料制成，通过增设卡持盲槽18，相较于凸耳17采用实芯制成，减少凸耳17的厚度，避免凸耳17厚度较大因塑料缩水率而导致凸耳17制造不良；根据实际需要，机壳1上还可以设置有两个卡块(图中未示出)，两 个卡块用于分别突伸入两个卡持盲槽18内。
当固定圈16安装在机壳1上之后，机壳1的卡块突伸入卡持盲槽18内，利用卡持盲槽18的侧壁挡止卡块，实现机壳1对固定圈16的限位，当充气机组装完成后，有效防止固定圈16相对机壳1发生移动。
其中一个所述凸耳17上设置有限位凸块19，机壳1上设置有用于容设限位凸块19的限位凹槽(图中未示出)。在固定圈16与机壳1安装的过程中，先将限位凸块19对准限位凹槽，然后组装机壳1及固定圈16，使得限位凸块19插入限位凹槽内，实现固定圈16与机壳1的准确对位，防止固定圈16因安装位置错误而导致充气机组装不良。
所述驱动电机3上设置有环形盲槽21，环形盲槽21自驱动电机3的外表面凹设而成，固定圈16容设在环形盲槽21内，利用环形盲槽21的侧壁挡止固定圈16，防止固定圈16相对驱动电机3发生相对移动，固定圈16的主体部分未突伸出驱动电机3的外表面，即固定圈16除了两个凸耳17之外其余的部位完全没入环形盲槽21内，避免固定圈16阻挡流经驱动电机3与机壳1之间的过气间隙内的流动空气，确保散热风扇6所驱动的空气流动时的平稳性，辅助提升散热效果。
所述驱动电机3上设置有与环形盲槽21连通的防转槽22，防转槽22自环形盲槽21的侧壁凹设而成，固定圈16上设置有防转片23，当固定圈16套设在驱动电机3上之后，防转片23突伸入防转槽22内，利用防转槽22的侧壁抵触防转片23，防止固定圈16与驱动电机3发生相对转动。本实施例中，凸耳17同时与固定圈16及防转片23连接，延长凸耳17的长度，辅助延长卡持盲槽18的长度，提升卡块与凸耳17之间的卡持效果。
本实施例中，所述固定圈16采用软胶制成，例如，固定圈16采用硅胶制成，利用软胶更好地吸收驱动电机3运转时对机壳1造成的冲击。
所述机壳1设有抓柄24，抓柄24的两端分别连接至机壳1，抓柄24与机壳1之间形成有让位孔25(图中未标号)，实际使用时，使用者将手插入让位 孔25内，然后用手握持住抓柄24，机壳1方便地移动充气机，提升客户的体验度。优选地，抓柄24上还设置有用于抵触使用者的手的摩擦凸起26，增大手与握柄24之间的摩擦力，摩擦凸起26的数量为多个，多个摩擦凸起26共线设置，多个摩擦凸起26沿握柄24的长度方向设置而成。
以上内容仅为本发明的较佳实施例，对于本领域的普通技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本发明的限制。
