请一并参阅图1及图6，现对本发明提供的传动装置进行说明。作为本发明的第一具体实施，上述传动装置，包括：输出轴10；与上述输出轴10连接的用于带动上述输出轴10作旋转运动或者回旋振动的输出机构20；第一驱动机构30；与上述第一驱动机构30连接的用于将上述第一驱动机构30输出的动能转变成旋转运动传动至输出机构20的旋转传动机构40；与上述第一驱动机构30连接的用于将上述第一驱动机构30输出的动能转变成回旋振动传动至输出机构20的回旋传动机构50；以及，用于切换上述输出机构20与上述旋转传动机构40连接，且上述输出机构20与上述回旋传动机构50分离；或者，上述输出机构20与上述回旋传动机构50连接，且上述输出机构20与上述旋转传动机构40分离的第二驱动机构60。其中，在本实施例中，当上述输出机构20上升时，上述输出机构20与上述回旋传动机构50连接且上述输出机构20与上述旋转传动机构40分离；当上述输出机构20下降时，上述输出机构20与上述旋转传动机构40连接且上述输出机构20与上述回旋传动机构50分离。
本发明提供的传动装置，与现有技术相比，通过旋转传动机构40将上述第一驱动机构30输出的动能转变成旋转运动传动至输出机构20，通过回旋传动机构50将上述第一驱动机构30输出的动能转变成回旋振动传动至输出机构20，且第二驱动机构60可以在上述输出机构20与上述旋转传动机构40连接，且上述输出机构20与上述回旋传动机构50分离；或者，上述输出机构20与上述回旋传动机构50连接，且上述输出机构20与上述旋转传动机构40分离之间自由切换。当上述输出机构20与上述旋转传动机构40连接且上述输出机构20与上述回旋传动机构50分离时，上述旋转传动机构40通过上述输出机构20带动上述输出轴10作旋转运动；当上述输出机构20与上述回旋传动机构50连接且上述输出机构20与上述旋转传动机构40分离时，上述回旋传动机构50通过上述输出机构20带动上述输出轴10作回旋振动，从而实现了同一个洁面刷可以根据实际需要在旋转运动和回旋振动之间自由切换，有效解决了现有技术中的洁面仪在没有更换洁面刷的情况下无法同时实现旋转与回旋振动功能的技术问题，且结构简单，使用方便快捷。
进一步地，如图3所示，上述输出轴10上设有第一齿轮11，上述输出机构20包括第一轴21、用于连接上述旋转传动机构40的第二齿轮22以及用于与上述回旋传动机构50连接以带动上述第二齿轮22转动的第三齿轮23，上述第二齿轮22和上述第三齿轮23均套于上述第一轴21上，上述第一齿轮11与上述第二齿轮22相互啮合。上述第二驱动机构60包括推动上述第二齿轮22及上述第三齿轮23沿上述第一齿轮11的轴向往复移动，以使上述第三齿轮23与上述回旋传动机构50连接并使上述第二齿轮22与上述旋转传动机构40分离，或者使上述第三齿轮23与上述回旋传动机构50分离并使上述第二齿轮22与上述旋转传动机构40相连的切换组件。当上述输出机构20上升时，第三齿轮23与上述回旋传动机构50连接且第二齿轮22与上述旋转传动机构40分离，第二齿轮22始终保持与第一齿轮11啮合，从而使得回旋传动机构50将上述第一驱动机构30输出的动能转变成回旋振动传动至输出轴10。当上述输出机构20下降时，第三齿轮23与上述回旋传动机构50分离且第二齿轮22与上述旋转传动机构40连接，从而使得旋转传动机构40将上述第一驱动机构30输出的动能转变成旋转运动传动至输出轴10。
优选的，在本实施例中，上述第二齿轮22与上述第三齿轮23为独立设置的两个，且上述第二齿轮22的直径大于上述第三齿轮23的直径。应当说明的是，上述第二齿轮22与上述第三齿轮23的设置方式并不局限于此，例如，在本发明的其他较佳实施例中，上述第二齿轮22与上述第三齿轮23还可以为同一齿轮的轴向的两段，即上述第二齿轮22与上述第三齿轮23为一体成型设置。
进一步地，如图3、图4所示，上述旋转传动机构40包括安装于上述第一驱动机构30上的主动齿轮41以及用于连接上述第二齿轮的从动齿轮组42，上述主动齿轮41与从动齿轮组42啮合。上述第一驱动机构30驱动上述主动齿轮41旋转，从而带动上述从动齿轮组42旋转。在本实施例中，上述从动齿轮组42的数量为多个，每个从动齿轮组42均包括同轴设置的第一从动齿轮421与第二从动齿轮422，应当说明的是，上述从动齿轮组42的数量也可根据实际需要设置，例如可以设置成三组、四组或者多组。上述同轴设置的第一从动齿轮421与第二从动齿轮422的直径可以相同也可以不同，数量也可以可根据实际需要设置，在此不做任何限制。上述第一驱动机构30可以为能够产生转动的电机、液压马达或者其他驱动机构，或者上述第一驱动机构30也可以为能够产生直线运动的推杆、气缸等驱动机构，再通过将直线运动转为旋转运动，例如通过齿轮齿条等将直线运动转为旋转运动。
进一步地，如图3所示，上述切换组件为电磁切换组件，上述电磁切换组件包括用于带动上述第二齿轮22和上述第三齿轮23移动的电磁芯以及用于驱动上述电磁芯移动的电磁线圈61，上述电磁芯与上述第二齿轮22相连。在本实施例中，上述电磁芯与上述第一轴21是由同种材质一体成型，即上述第一轴采用与上述电磁芯同种材质制成，从而使得上述第一轴21具有电磁芯的功能。当然，也可以通过将上述电磁芯设于上述第一轴21上，同样能够带动上述第二齿轮22和上述第三齿轮23往复运动。当通电时，上述电磁线圈61产生磁力，使得上述第一轴21上升，当断电时，上述电磁线圈61的磁力消失，上述第一轴21恢复到初始位置。
进一步地，如图3、图4、图5及图6所示，上述回旋传动机构50包括第二轴52、可绕着上述第二轴52摆动的回旋连杆53以及用于带动上述回旋连杆53绕上述第二轴52摆动的偏心件51，上述回旋连杆53上开设有固定孔531，上述第二轴52固定于上述固定孔531中，上述回旋连杆53上设有活动槽532，上述偏心件51位于上述活动槽532内，上述偏心件51与上述第一驱动机构30相连，上述回旋连杆53上具有用于连接上述第三齿轮23的齿牙。进一步地，在本实施例中，上述齿牙位于上述回旋连杆53上远离上述活动槽532的一端。应当说明的是，上述齿牙的设置位置并不局限于此，在本发明的其他较佳实施例中，上述齿牙还可以根据实际需要设置于其他位置上。上述第一驱动机构30带动上述偏心件51转动以实现上述偏心件51与上述回旋连杆53碰撞，由于回旋连杆53在偏心件51的带动下会产生周期性的回旋运动，且由于偏心件51与回旋连杆53的高频率碰撞会产生振动效果，因此最终能够实现回旋振动的效果。
进一步地，上述第二轴52通过轴承与上述回旋连杆53连接，从而使得上述回旋连杆53可以绕着上述第二轴52作回旋振动。优选的，在本实施例中，上述回旋连杆53的形状为长条形。上述活动槽设于上述回旋连杆的一端，上述活动槽设于上述回旋连杆的另一端。应当说明的是，上述回旋连杆53的形状并不局限于此，在本发明的其他较佳实施例中，上述回旋连杆53还可以是其他形状。
进一步地，上述偏心件51的转动轴线与上述第一驱动机构30的转动轴线相隔，即上述偏心件51的转动轴线与上述第一驱动机构30的转动轴线不在同一直线上，在本实施例中，上述偏心件51呈柱状，上述偏心件51设置于上述第一驱动机构30的输出轴上。优选的，上述偏心件51上套设有可更换的耐磨套511，可以有效延长偏心件51的使用寿命。
进一步地，如图1、图2所示，上述传动装置包括有壳体70，上述壳体70内具有容置腔701，上述输出轴10的一端露出上述壳体70外，上述输出机构20、上述第一驱动机构30、上述旋转传动机构40、上述回旋传动机构50、上述第二驱动机构60固定于上述容置腔701内。优选的，上述壳体70包括上壳体71以及与上述上壳体70连接的下壳体72，上述上壳体71与下壳体72对接并围合形成上述容置腔701，上述上壳体70与上述下壳体70通过螺钉连接固定，当然，上述上壳体70与上述下壳体70的连接固定方式并不局限于此，在本发明的其他较佳实施例中，上述上壳体70与上述下壳体70还可以通过卡扣或者其他连接方式固定。
本实施例的工作过程如下所示：
当输出轴10需要实现回旋振动时，首先，将电磁线圈61通电，上述电磁线圈61产生磁力，使得上述第一轴21上升，上述第三齿轮23与上述回旋传动机构50连接且上述第二齿轮22与上述旋转传动机构40分离，第二齿轮22始终保持与第一齿轮11啮合，从而使得回旋传动机构50将上述第一驱动机构30输出的动能转变成回旋振动传动至输出轴10。
当输出轴10需要实现旋转运动时，首先，将电磁线圈61断电，上述电磁线圈61的磁力消失，上述第一轴21下降到初始位置，第三齿轮23与上述回旋传动机构50分离且第二齿轮22与上述旋转传动机构40连接，从而使得旋转传动机构40将上述第一驱动机构30输出的动能转变成旋转运动传动至输出轴10。
请一并参阅图7及图13，作为本发明的第二具体实施例，该第二具体实施例提供的传动装置的结构与第一具体实施例提供的传动装置的结构基本相同，其所不同的是：

进一步地，上述第二驱动机构60还包括用于推动上述第二齿轮22与上述第三齿轮23复位的第一复位弹性件64，上述第一复位弹性件64套设于上述第一轴21上，上述第一复位弹性件64的一端与上述第一轴21固定相连，上述第一复位弹性件64的另一端抵持上述第三齿轮23。优选的，上述第三齿轮23具有凹腔24，上述第一复位弹性件64套设于上述第一轴21上且上述第一复位弹性件64的另一端位于上述凹腔24内。当通电时，上述导杆63向上活动，上述第一复位弹性件64处于压缩状态；当断电时，上述导杆63在第一复位弹性件64的作用下向下活动。优选的，上述第一复位弹性件64为弹簧。
进一步地，上述第二驱动机构60还包括用于推动上述导杆63复位的第二复位弹性件65，上述第二复位弹性件65套于上述导杆63远离上述第二齿轮22的一端，且上述第二复位弹性件65的一端与上述导杆63固定相连，上述第二复位弹性件65的另一端抵持上述盒体62。上述第二复位弹性件65为弹簧。
进一步地，如图11所示，上述回旋连杆53的形状为L形。上述回旋连杆53包括活动部54以及与上述活动部54连接的连接部55，上述活动部54与上述连接部55的连接处一体向下延伸出延伸部56，上述延伸部56具有通孔，上述活动槽532设于上述活动部54上，上述固定孔531设于上述活动部54与上述连接部55的连接处，且上述固定孔531的中心轴线与上述通孔的中心轴线一致。上述回旋连杆53上的齿牙设于上述连接部55上，从而使得回旋振动过程中更加平稳。
进一步地，如图7、图8所示，上述传动装置还包括外盖80，上述外盖80套设于上述壳体70外。上述输出轴10的一端伸出上述外盖80外。
