粉筒
本申请要求于2020年03月03日提交中国专利局、申请号为202020245447.6、申请名称为“一种粉筒”；2020年03月20日提交中国专利局、申请号为202020359423.3、申请名称为“一种粉筒”的中国专利申请的优先权，其全部内容通过交叉引用结合在本申请中。
技术领域
本申请涉及图像形成技术领域，具体涉及一种粉筒。
背景技术
电子成像装置是通过电照相成像处理技术在记录材料上形成图像的设备，例如：电子照相复印件、激光打印机、电子照相打印机、传真机、文字处理机等。其内部能够可拆卸地安装用于供应显影剂(如碳粉)的粉筒，随着显影剂不断地参与电子成像，当粉筒中的显影剂消耗殆尽，需要用户及时替换粉筒或者向粉筒中注入新的显影剂，这使得粉筒成为电子成像中更换频繁的易耗件之一。
现有技术中，粉筒在电子成像装置内用于接收显影剂的显影剂补充装置中安装和拆卸。而粉筒在该显影剂补充装置的每一次安装和拆卸操作都涉及到粉筒出粉口与显影剂补充装置受粉口的联通和断开。
图1为现有技术所公开的一种能够可拆卸地安装在显影剂补充装置上的粉筒的爆炸视图。粉筒1包括：用于容纳显影剂的粉筒筒体2，位于粉筒筒体2长度方向上第一端21处的出粉结构3、相对于出粉结构3滑动的滑板4，其中，出粉结构3包括上凸缘部分3a、下凸缘部分3b，以及在出粉结构3内还包括搅拌架、混粉部、出粉口等用于将粉筒筒体2中的碳粉排出的结构，根据不同排出原理可设计不同的结构。图2a～图2c中，图2a为显影剂补充装置及的结构示意图；图2b为显影剂补充装置的局部放大的截面图；图2c为显影剂接收部的透视图。显影剂补充装置8中至少包括显影剂接收部11、第一、第二滑板卡接部8a和8b，显影剂接收部11包括接收口11a、用于开启和关闭接收口11a的结合部11b、密封件13，其中，位于接收口11a中的挡块15用于密封接收口11a，通过结合部11b带动显影剂接收部11的上升和下降使接收口11a与挡块15处于间隔和接触状态，从而开启和关闭接收口11a，此外还可设置弹性件12以使结合部11b克服弹性件12的弹力上升和在弹性件12的弹力作用下下降。图3a～图3c中，示出了出粉结构3的下凸缘部分3b上的导轨结构，以及该导轨结构用于提升显影剂补充装置中的结合部11b，以打开显影剂补充装置的接收口11a的过程。其中，导轨结构含有一上升的第一部分3b2和第二部分3b4，随着粉筒1沿箭头A方向的安装，由第一部分3b2引导结合部11b上升使接收口11a开启，并在第二部分3b4上继续移动至粉筒中的出粉口(未示出)完全打开的位置，以使粉筒中的出粉口与接收口11a形成一贯通的显影剂排放通道。在粉筒的拆卸过程中，同理，当粉筒1沿安装方向A的反方向B运动，使粉筒中的出粉口及接收口11a分别关闭。然而，在依靠导轨的第二部分3b4引导结合部11b的移动过程中，由于接收口11a已经完全开启，且已上升至足够高度，并会先后分别贴合出粉结构3、 滑板4底部的相应部位并随着粉筒的安装/拆卸动作继续沿A/B方向移动，即使做到密封和位置的对准，仍不可避免地发生相对位移，由于显影剂为极轻的微粒粉末，很容易在相对位移发生因摩擦震动时因各密封件的弹性变形而受到弹力造成显影剂飞散。

实施例一
本实施例提供了一种粉筒，可拆卸地安装在电子成像设备中。本申请的粉筒与现有技术的粉筒安装方式相似，也是安装在位于电子成像设备中的显影剂补充装置8 上，如图2a～图2c。
参照图4～图6所示，粉筒100包括外壳110、粉筒筒体120和出粉结构130。粉筒筒体120在本实施例中大体为长圆柱结构，在粉筒筒体120长度的延伸方向上，粉筒筒体120的两端分别为第一端121和第二端122，第一端121为出粉端，并且粉筒筒体120内部具有容纳腔，用于存储显影剂。当粉筒100被安装于电子成像设备时，该粉筒筒体120在电子成像设备中能够被驱动绕其旋转轴L旋转工作。出粉结构130连接于第一端121，用于将粉筒筒体120中的显影剂排出至电子成像设备中参与显影。外壳110包覆于出粉结构130。
进一步地，在粉筒筒体120上设置有齿圈123。齿圈123可以与电子成像设备啮合，以从电子成像设备获取旋转驱动力，从而带动粉筒筒体120绕其旋转轴L并相对于出粉结构130旋转。
出粉结构130包括连接部160和固定出粉板180，连接部160连接于粉筒筒体120的第一端121，并且连接部160开设有出粉口140(参照图7所示)。固定出粉板180连接于连接部160，且固定出粉板180具有一开口181。在第一方向(图6中的Z方向)上，出粉口140的投影与开口181的投影至少部分重叠，在本实施例中，出粉口140在第一方向上的投影完全落入开口181在第一方向上的投影内。出粉结构130内部的机械结构，可以为现有技术中的根据不同送粉原理所设置的结构，在此不做赘述。
在本实施例中，固定出粉板180和出粉口140均位于出粉结构130的底部，具体地，出粉口140可开设在连接部160底部并相对于固定出粉板180更靠近旋转轴L。开口181开设于固定出粉板180底部，开口181的形状尺寸大于出粉口140，在第一方向上，出粉口140位于开口181的上方，即，出粉口140与旋转轴L之间的距离小于开口181与旋转轴L之间的距离，使得粉筒筒体120内部存储的显影剂可通过出粉口140及开口181排向粉筒的外部。
出粉结构130还包括活动出粉板190，在第一方向上，活动出粉板190设于连接部160和固定出粉板180之间。在活动出粉板190上设置有出粉孔(未示出)，当粉筒安装进电子成像设备中的显影剂补充装置时，第一滑板卡接部8a、第二滑板卡接部8a能够卡接活动出粉板190的两侧凸块(未示出)，使活动出粉板190与显影剂补充装置8相接合保持固定状态，固定出粉板180则随着粉筒100沿第二方向(图6中的+X方向)继续进行安装动作，使活动出粉板190与固定出粉板180发生相对移动，当固定出粉板180上的开口181经活动出粉板190上的出粉孔与出粉口140逐渐相重合时，形成排出通道，粉筒筒体120内部存储的显影剂可通过出粉口140、活动出粉板190上的出粉孔及开口181排向粉筒的外部。
在粉筒安装至电子成像设备时，为了方便对显影剂接收部的移动进行引导，出粉结构130还包括引导部131，通过引导部131对显影剂补充装置8中显影剂接收部11的结合部11b进行引导，以简单的结构和行程开启接收口11a。具体地，参照图6所示，固定出粉板180具有远离粉筒筒体120的第一端体182，以及靠近粉筒筒体120的第二端体183，在旋转轴L方向上，固定出粉板180的两侧镜像设置有具有向 上折弯的侧壁，引导部131为分别自固定出粉板180的两侧的侧壁上延伸出的突出结构。
具体的，引导部131连接于固定出粉板180的侧壁上，且引导部131在自第一端体182向第二端体183的方向上呈直线倾斜设置，或呈曲线倾斜设置，且引导部131具有第一端部131a和第二端部131b，第二端部131b相对于第一端部131a更靠近旋转轴L，即，在第一方向上，第二端部131b位于第一端部131a的上方，且，第二端部131b位于出粉口140的上方。在本实施例中，在第二端部131b处，引导部131所倾斜的斜率不为0，换句话说，在第二端部131b附近的引导部131与轴L不平行。当粉筒安装至电子成像设备时，显影剂接收部沿引导部131由第一端部131a移动至第二端部131b，使粉筒筒体120内的显影剂能够经出粉口140、显影剂接收部流入电子成像设备中。
同时参照图8a、图8b所示，以粉筒的安装操作为例，随着粉筒100沿第二方向(图8a中的+X方向)安装在显影剂补充装置8上，在图8a中，粉筒位于待开启接收口11a的第一位置处。用于开启和关闭接收口11a的结合部11b位于引导部131的第一端部131a处，随着粉筒沿着第二方向进一步移动，引导部131导引结合部11b逐渐攀升至第二端部131b处，此时，结合部11b的向上运动逐渐打开接收口11a，并且随着上述第一滑板卡接部8a、第二滑板卡接部8b对活动出粉板190的卡接使活动出粉板190上的出粉孔、出粉口140及开口181逐渐形成显影剂排出通道，最终在第二端部131b处完成接收口11a与排出通道的吻合对接，此时，该排出通道位于经过第二端部131b且垂直于旋转轴L的平面处，可允许粉筒筒体120内的显影剂流入电子成像设备中。即，在图8b中，粉筒位于形成排出通道并开启接收口11a的第二位置处，在该第二端部131b处使粉筒中的显影剂得以顺利流至显影剂补充装置中。在此之前的移动过程中，接收口11a则处于未完全开启的状态。由此，在引导部131的作用下使接收口11a在粉筒安装过程中不会过早地抵接到固定出粉板180或活动出粉板190，不会出现粉筒在安装移动中使显影剂因摩擦震动等原因造成的显影剂飞散。
实施例二
本实施例在实施例一的基础上，出粉结构130还包括保持部132。
参照图9～图10b所示，其中，图10a和图10b分别为粉筒处于待开启接收口11a的第一位置和形成排出通道并开启接收口11a的第二位置。出粉结构130还包括保持部132，在粉筒安装于电子成像设备时，保持部132用于对结合部进行限位。优选地，在固定出粉板180的两侧侧壁上镜像设置有一对保持部132。保持部132可以为自固定出粉板180的侧壁向外伸出的突起，可以设置在引导部131以外，也可设置在引导部131上。当保持部132设置在引导部131以外时，保持部132可以是与引导部131的第二端部131b相间隔一段距离的独立部分，即，保持部132与引导部131的第二端部131b间隔设置，以使移动至第二端部131b处的结合部11b能够卡接在保持部132与引导部131之间的间隙处，如图10b所示，以保持接收口11a的开启状态。
此外，对保持部132可做其它结构的变形，例如可以是如图11所示的薄片结构133，或者如图12所示的圆柱结构134，亦或者横断面为三角形、锥形、规则或不规则的多边形等结构，在粉筒位于形成排出通道并开启接收口11a的位置时，利用保持部132与引导部131之间的间隙使结合部11b保持在开启接收口11a的位置。以及，当保持部132设置在引导部131上时，保持部132还可以是位于第二端部131b的具有高摩擦系数的表面，或者如图13所示的凹槽135，直接利用摩擦力或者凹槽卡位使结合部11b保持在保持部上，以保持开启接收口11a的位置。
优选地，还可在引导部131的第二端部131b、保持部132的与结合部11b相卡接的接触部分(即位于间隔处的部分)设置倒角结构，使粉筒在拆卸过程中更加容易脱离该卡接结构。
实施例三
本实施例提供了一种新的粉筒方案。在本实施例中没有明确指出的部分与现有技术及实施例一种保持相同，本实施例主要介绍用于引导电子成像设备的结合部11b的结构。
参照图14ˉ图16所示，图14为本实施例中出粉结构的示意图，图15为本实施例中出粉结构的爆炸图，图16为固定出粉板的局部放大图。出粉结构230包括连接部260、固定出粉板280和引导部231(导向件)。连接部260连接于粉筒筒体120的第一端，固定出粉板280连接于连接部260，引导部231可移动地设置于固定出粉板280的侧壁上。
参照图17ˉ图19所示，图17为引导部远离固定出粉板一侧的面的示意图，图18为引导部靠近固定出粉板一侧的面的示意图，图19为引导部的立体示意图。如图14及图17至19所示，引导部231包括引导轨231c，该引导轨231c具有第一端部231a和第二端部231b。当粉筒安装时，电子成像设备的结合部11b沿引导轨231c由第一端部231a运动到第二端部231b。
在本实施例中，出粉结构230还包括第一受力块234，第一受力块234连接于引导部231并位于第二端部231b的上部，该第一受力块234用于和结合部11b配合，在粉筒沿第二方向安装在电子成像设备的过程中，使得结合部11b和第一受力块234能够抵接并随着粉筒的安装及结合部的运动，推动整个引导部231运动，即，推动引导部231沿与第二方向相反的方向移动，即由远离连接部260的方向向靠近连接部260的方向(图14中的-X方向)移动。
进一步地，固定出粉板280包括轨道284、抵接块285、防脱块286和平衡块287。优选地，在抵接块285靠近防脱块286的一端还设置有倒角285a。引导部231还包括辅助导轨231e，辅助导轨231e与引导部231的引导轨231c位于同一侧并相互配合，用于辅助结合部11b更加流畅的在引导部231的引导轨231c上运动。引导部231还包括配合件231g、第一辅助块231f和第二辅助块231g，配合件231g、第一辅助块231f和第二辅助块231g均设于引导部231背对辅助导轨231e、引导轨231c的一侧。配合件231g呈“工”字型结构，其用于安装在轨道284中，第一辅助块231f用于安装于抵接块285竖直方向的上部，第二辅助块231g用于安装于平衡块287上 方，通过第一辅助块231f、第二辅助块231g以及“工”字配合件231g共同作用，保证引导部231尽可能平稳的移动，减少晃动。
出粉结构230还包括锁定件232和弹性件233，锁定件232活动设置于引导部231，且锁定件232在引导部231上具有解锁位置和锁定位置，在锁定件232随引导部231沿第二方向的反向(图14中的-X方向)移动的过程中，锁定件232能够伸出于引导部231，以对结合部11b进行限位，此时锁定件232到达其锁定位置。弹性件233设于锁定件232和引导部231之间，用于作用于锁定件232，在锁定件232随引导部231沿第二方向移动的过程中，弹性件233作用于锁定件232，使锁定件232缩回，以释放对结合部11b的限位，此时锁定件232到达其解锁位置。进一步地，在第一受力块234相对于安装到位的结合部11b的另一侧还设置有空隙231d，使得锁定件232可以穿过空隙231d穿出。
图20和图21为锁定件不同视角的立体视图。锁定件232包括稳定部232c和第二受力块232a，第二受力块232a连接于稳定部232c，在锁定件232随引导部231沿与第二方向相反的方向移动时，稳定部232c与抵接块285接触干涉，使第二受力块232a从空隙231d中伸出，从而可以和电子成像设备的结合部11b接触受力。
进一步地，在引导部231的背部还设有一个用于固定弹性件233一端的第一固定部231h，优选地，第一固定部231h为不贯穿引导部231的孔。锁定件232还包括一个用于固定弹性件233另一端的第二固定部232b，优选地，第二固定部232b为连接于稳定部232c的凸起柱，弹性件233为压簧。组装时，使弹性件233的一端套设于第二固定部232b，使弹性件233的另一端位于第一固定部231h，进而对弹性件233进行限位，即，使弹性件233设于稳定部232c和引导部231之间。
为了防止锁定件232在随引导部231一起在第二方向上运动时位置发生偏移，稳定部232c可以插入“工”字配合件231g的凹槽中，从而保证锁定件232和引导部231之间尽可能的不发生相对运动。
图22为粉筒装入电子成像设备前出粉结构的示意图，图23为图22移除引导部的内部结构示意图，图24为粉筒在电子成像设备内安装到位时出粉结构的示意图，图25为图24移除引导部的内部结构示意图。参照图22和图23所示，在粉筒安装进电子成像设备前，锁定件232位于防脱块286和抵接块285之间，锁定件232并没有相对于引导部231伸出。在安装过程中，电子成像设备的结合部11b沿引导部231的第一端部231a向第二端部231b运动。之后结合部11b会和第一受力块231c抵接，并带动整个引导部231和锁定件232沿轨道284运动。由于锁定件232和抵接块285接触干涉，第二受力块232a逐渐从空隙231d中伸出，弹性件233变成受压缩状态。当粉筒安装完毕，结合部11b运动到电子成像设备设定好的安装位置时，到达图24和图25所示的状态。此时，同实施例一，在经过导轨第二端部231b且垂直于旋转轴的平面处，可形成排出通道，允许粉筒筒体内的显影剂流入电子成像设备中，粉筒可以正常工作。当粉筒完成工作需求取出时，结合部11b与第二受力块232a抵接并沿轨道284以相反于第二方向(安装方向)的方向运动并带动引导部231和锁定件232一同运动，直到运动到图22和图23的位置时，锁定件232不再和抵 接块285接触干涉，弹性件233由于弹性势能的释放推动第二受力块232a从空隙231d中缩回并不在和结合部11b接触。之后结合部11b沿引导轨231的第二端部231b运动到第一端部231a，从而完成取出粉筒过程中结合部11b的脱离。
以上所述，仅为本申请较佳的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应该以权利要求的保护范围为准。
