Description

一种显影盒 技术领域
本发明涉及成像设备技术领域，尤其涉及一种显影盒。
背景技术
成像设备在记录介质上形成图像，成像设备的示例包括电子复印机、电子照相打印机(例如，激光束打印机、LED打印机等)、传真机、文字处理器等。
成像设备具备利用显影剂使感光鼓上的静电潜影显影的显影盒。显影盒具有能够转动地支承于其壳体内的显影辊，通过将收纳在壳体内的调色剂从显影辊供给到感光鼓来进行显影。
成像设备工作过程中，显影辊与感光鼓需要抵紧接触，当成像设备不工作时，显影辊与感光鼓需要分隔开一定距离，避免显影辊与感光鼓长时间接触而导致感光鼓被显影辊上附着的多余显影剂污染或者显影辊变形或者感光鼓磨损等问题。
如图1和图2所示，现有的一种显影盒B1，显影盒B1长度方向的一端为驱动端，另一端为导电端，导电端的分离构件包括摆杆72和弹簧73，其中弹簧73一端与摆杆72抵接，另一端与轴承46抵接。摆杆72与轴承46活动连接，当轴承46固定安装到显影盒B1上后，摆杆72受力可绕固定轴46f转动，并给予弹簧73一个作用力，使其带动显影盒B1一体转动。驱动端的分离构件120包括摆杆70和弹簧71，连接关系与导电端类似.
如图3和图4所示，现有的一种成像设备A1中设有摆动引导件80，其中摆动引导件80上设有滑槽，可与显影盒B1两端的定位柱配合。并且摆动引导件80由侧板90支撑而能够沿着箭头N5的方向和箭头N6的方向旋转。
另外，成像设备A1还设置有驱动端按压件150，按压件由底板(未示出)支撑并能够沿着箭头N7的方向和箭头N8的方向移动，从而使得感光鼓10的表面和显影辊13接触和分离。成像设备还设有导电端按压件151、导电端摆动引导件81。
如图4所示，导电端按压件151的第二接触面151b和摆杆72的第一接触面72a接触，摆杆72抵抗弹簧73的偏压力沿着箭头NH9的方向旋转。摆杆72的第三接触面72c随后压缩弹簧73，受到偏压力FH10，此时摆杆72也受到摆动引导件151的作用力FH11，以使得与力矩MH10平衡的力矩作用在摆杆70上。因此，力FH11的外力作用在显影盒B1上。显影盒受力转动，从而显影辊13与感光鼓10接触。
如图5所示，导电端按压件151沿着箭头NH8的方向移动距离δh7。因此，显影盒B1以摆动引导件81的被支撑突出部81g为中心沿着箭头N5的方向旋转， 显影辊13和感光鼓10相互间隔开距离δ8。
基于图像图像质量、显影辊和感光鼓的寿命考虑，期待一种新的结构在成像设备不工作时使显影辊和感光鼓分离且在成像设备工作时使显影辊和感光鼓接触。

实施例一
如图6和图7所示，本实施例提供一种显影盒200，包括显影框架、显影辊220、搅拌架(未示出)、驱动组件、电极组件240和分离组件。
如图6和图7所示，显影框架包括盒体210、驱动端轴承211、导电端端盖212和驱动端盖213。显影框架长度方向的一端为驱动端，另一端为导电端。盒体210内部具有可容纳显影剂的粉仓，显影剂可以是碳粉。驱动端轴承211设置在盒体210的驱动端的端面上，驱动端盖213设置在驱动端轴承211的外侧，即驱动端盖213相比于驱动端轴承211离盒体210更远。导电端端盖212设置在盒体210的导电端的端面上，即导电端端盖212和驱动端端盖213分别位于盒体210长度方向的两端的外侧。
如图6和图7所示，显影辊220可旋转地支撑于显影框架上，具体的，显影辊220的长度方向与显影框架的长度方向一致，显影辊220的旋转轴线沿显影辊220的长度方向延伸。显影辊220的两端分别支撑于驱动端轴承211和导电端端盖212。
搅拌架可旋转地支撑在显影框架上且位于盒体210的粉仓内，具体的，搅拌架的两端支撑在驱动端轴承211和导电端端盖212上，搅拌架的长度方向与显影框架的长度方向一致，搅拌架能够沿其在长度方向上的轴线周向旋转，搅拌架可以具有一个或多个叶片，通过旋转带动叶片来搅拌粉仓内的显影剂，防止粉仓内的显影剂结块，同时也可以向显影辊220方向输送显影剂，被带电的显影辊220吸附。
如图6和图8所示，驱动组件，设置于驱动端轴承211的外侧(背向盒体210的一侧)，包括动力接收件231和齿轮组。动力接收件231用于接收成像设备A1的驱动力并通过齿轮组将驱动力传递，进而带动显影辊220和搅拌架旋转。 齿轮组包括显影辊齿轮232和搅拌架齿轮233，显影辊齿轮232固定在显影辊220的轴在长度方向上的一端且位于驱动端轴承211外侧，显影辊齿轮232与动力接收件231啮合，从而使显影辊220能够接收驱动力旋转。搅拌架齿轮233固定在搅拌架在长度方向上的一端且位于驱动轴承外侧，搅拌架齿轮233与动力接收件231啮合，使搅拌架能够接收驱动力旋转。显影辊齿轮232和搅拌架齿轮233均可以直接或间接地与动力接收件231啮合。
如图7和图9所示，电极组件240，设置于显影框架的导电端，位于导电端端盖212的内侧，导电端端盖212上设有开口，电极组件240的至少一部分能从开口中暴露，从而与成像设备A1电连接，电极组件240还与显影辊220在长度方向的另一端电连接，从而使显影辊220带电，能够吸附显影剂。
如图9和图10所示，分离组件，能够接收成像设备A1的作用力，带动显影盒200向靠近或远离感光鼓的方向移动，使显影辊220与感光鼓接触或分离。分离组件可以设置于显影框架的驱动端，也可以设置于显影框架的导电端，还可以同时设置在显影框架的驱动端和导电端。
本实施例中，分离组件包括分离接触件250，分离接触件250设置于显影框架上，能够接收成像设备A1的作用力而在第一位置和第二位置之间发生弹性形变。本实施例中的分离接触件250相当于现有技术中的摆杆72。
具体的，如图9和图10所示，分离接触件250包括依次连接设置的连接部250a、杆部250b和配合部250c，即连接部250a为分离接触件250的一端，配合部250c为分离接触件250的另一端，连接部250a用于将分离接触件250装配于显影框架上，配合部250c用于接收成像设备A1的作用力。
如图9和图10所示，以分离接触件250设置于显影框架的导电端为例，导电端端盖212内侧设有支撑柱2121，支撑柱2121从导电端端盖212的内侧面上突出，分离接触件250可拆卸地连接在支撑柱2121上，具体的，连接部250a上设有通孔，通过通孔套设于支撑柱2121使分离接触件250装配在导电端端盖212上，并且能够以支撑柱2121为中心旋转。杆部250b的长度方向沿与显影框架的长度方向相交的方向延伸，杆部250b的一端延伸至靠近导电端端盖212边缘的位置，配合部250c设置于杆部250b的端部，从而露出于导电端端盖212，便于与成像设备A1的导电端按压件151配合，接收作用力。
在一些其他的实施方式中，连接部250a还可以粘贴、焊接、卡合固定在导电端端盖212上。
进一步的，如图9和图10所示，导电端端盖212内侧还形成有第一突起251，第一突起251靠近支撑柱2121设置且位于支撑柱2121的下方，第一突起251的数量为两个，两个第一突起251夹持于分离接触件250的两侧。
进一步的，如图9和图10所示，分离接触件250采用弹性材料制成，可产 生弹性形变，导电端端盖212的内侧还设有限制部2122，限制部2122位于分离接触件250远离显影辊220的一侧，能够对分离接触件250形成阻挡，限制分离接触件250在远离显影辊220的方向的运动，在没有受到外力的作用下，分离接触件250位于与限制部2122接触的位置，分离接触件250未发生形变，此时分离接触件250所处的位置为第一位置，第二位置位于相比于第一位置更靠近显影辊220(或靠近感光鼓)的位置。
当分离接触件250处于第一位置时，显影盒200位于远离感光鼓的位置，显影辊220与感光鼓分离，当分离接触件250从第一位置运动到第二位置时，显影辊220与感光鼓相接触。
如图4、图9和图10所示，当成像设备A1工作时(打印任务进行时)，成像设备A1中的导电端按压件151沿NH7方向移动，与分离接触件250的配合部250c相抵接，对分离接触件250施加作用力FH11(推压力)，分离接触件250在第一突起251以下的部分发生形变，从第一位置形变至第二位置，同时，导电端按压件151的作用力FH11也作用在显影盒200上，显影盒200受力转动，向靠近感光鼓的方向转动，从而使显影辊220与感光鼓接触。分离接触件250形变对导电端按压件151产生偏压力，导电端按压件151也产生与偏压力方向相反的反作用力，反作用力作用于显影盒200，能使显影辊220进一步贴紧感光鼓。分离接触件250形变产生的偏压力也能起到缓冲作用，使显影辊220和感光鼓更好的接触，保证显影质量。
如图5、图9和图10所示，当成像设备A1结束打印后，成像设备A1中的导电端按压件151沿NH8方向移动，导电端按压件151与分离接触件250的配合部250c抵接，对其施加作用力，使整个显影盒200沿远离感光鼓的方向转动(如图5中的N5方向)，使显影辊220和感光鼓相互间隔开距离δ8，同时分离接触件250弹性形变恢复，从第二位置形变至第一位置，与限制部2122接触后不再向远离显影辊220的方向形变。
需要说明的是，上述分离组件不限于设置在导电端，也可以设置在驱动端，还可以设置于驱动端和导电端。当设置于驱动端时，分离接触件250设置于驱动端轴承211的外侧，驱动端轴承211的外侧设置支撑柱2121、第一突起251、限制部2122等结构，连接方式与分离组件设于导电端的一致，在此不再赘述。
作为实施例一的一个变形例，如图11所示，分离组件还可与导电端端盖212一体成型，并且取消了第一突起251，可选的，整个分离组件和导电端端盖212可采用POM材料制成，具体的，分离组件为分离接触件250，分离接触件250包括依次连接设置的连接部250a、杆部250b和配合部250c，即连接部250a为分离接触件250的一端，配合部250c为分离接触件250的另一端，连接部250a用于将分离接触件250装配于显影框架上，配合部250c用于接收成像设备A1 的作用力。其工作过程与上述分离组件一致，当成像设备A1工作时，分离接触件250受到成像设备A1的的导电端按压件151的作用力后，自身会发生弹性形变，使得显影盒200受力转动，向靠近感光鼓的方向转动，从而使显影辊220与感光鼓接触。当成像设备A1结束打印后，分离接触件受250到导电端按压件151的作用力，使得显影辊220和感光鼓间隔开一定距离，实现显影辊220与感光鼓的分离。
本实施例的分离组件结构简单，通过取消如现有技术中的弹簧结构，分离组件同样能够达到相同的分离效果，从而简化了结构并且安装简单，节约成本。
实施例二
本实施例提供另一种显影盒200，与实施例一相比，不同之处在于分离组件的结构不同。
本实施例中，如图12所示，分离组件包括分离接触件250和第一挡板253，取消实施例一的第一突起251结构，本实施例的分离接触件250不采用弹性材料制成，其自身不能弹性形变，分离接触件250的其他结构与实施例一相同。
如图12和图13所示，分离接触件250转动设置于导电端端盖212，能够接收成像设备A1的作用力而在第一位置和第二位置之间运动，即分离接触件250能够以支撑柱2121为中心转动。分离接触件250上设有第二突起250d，第二突起250d设置于分离接触件250的杆部250b位置，且位于分离接触件250朝向显影辊220的一侧。
如图12和图13所示，第一挡板253，设置于导电端端盖212的内侧面上，第一挡板253位于分离接触件250朝向显影辊220的一侧，第一挡板253的至少一部分为弹性材料制成，第一挡板253的该部分受力时能够弹性形变；也可以是整个第一挡板253均为弹性材料，例如第一挡板253是弹性硅胶板。
当分离接触件250位于第一位置时，第二突起250d与第一挡板253可以是未接触的状态，也可以是接触但不具有相互作用力的状态。
当分离接触件250接收成像设备A1的导电端按压件151的作用力从第一位置转动至第二位置的过程中，导电端按压件151的作用力也作用在显影盒200上，显影盒200受力转动，向靠近感光鼓的方向转动，从而使显影辊220与感光鼓接触；同时，在分离接触件250转动的过程中，第二突起250d抵压第一挡板253，第一挡板253发生形变，对分离接触件250产生沿着将分离接触件250从第二位置移动到第一位置的方向的偏压力，分离接触件250也产生与偏压力方向相反的反作用力，反作用力作用于显影盒200，能使显影辊220进一步贴近感光鼓。第一挡板253形变产生的偏压力也能起到缓冲作用，使显影辊220和感光鼓更好的接触，保证显影质量。
需要说明的是，上述分离组件不限于设置在导电端，也可以设置在驱动端，还可以设置于驱动端和导电端。
在一些实施方式中，导电端和驱动端的分离组件的结构可以相同，也可以不同，例如在导电端设置如实施例二中的分离组件，驱动端设置如实施例一中的分离组件，也可以是相反的设置，在此不作限制。
作为实施例二的一个变形例，如图14所示，第一挡板253的数量可以为两块，两块第一挡板253之间的间隔沿着第一位置朝向第二位置的方向逐渐变小，即两块第一挡板253呈“八”字形，在第一位置时，分离接触件250的第二突起250d插入到两块第一挡板253之间，可以与第一挡板253接触，也可以未接触，在分离接触件250接收导电端按压件151的作用力从第一位置转动到第二位置的过程中，第二突起250d挤压第一挡板253，使第一挡板253产生弹性形变，对分离接触件250产生沿着将分离接触件250从第二位置移动到第一位置的方向的偏压力。
显影盒200的其他结构与实施例一相似，在此不再赘述。
实施例三
本实施例提供一种显影盒200，与实施例一和实施例二相比，不同之处是分离接触件250为固定结构，可以省略支撑柱2121。
本实施例中，如图15所示，分离接触件250固定设置于导电端端盖212的内侧，分离接触件250的结构与实施例一和实施例二的相同，分离接触件250可以与导电端端盖212为一体成型结构，也可以是分体结构，通过粘贴、焊接、卡合或其他固定方式固定在导电端端盖212内侧。
分离接触件250通过配合部250c与成像设备A1的导电端按压件151接触，从而接收成像设备A1的作用力带动显影盒200在显影辊220与感光鼓接触的位置和显影辊220与感光鼓分离的位置之间运动。
本实施例的固定设置的分离接触件250结构简单，无需设置其他结构。
本实施例的分离接触件250可以设置于显影框架的一端或两端。
显影盒200的其他结构与实施例一相似，在此不再赘述。
实施例四
本实施例提供一种显影盒200，与实施例三相比，不同之处是，分离组件包括分离接触件250和弹性件254a。
本实施例中，如图16所示，分离接触件250固定设置于导电端端盖212的内侧，弹性件254a设置在分离接触件250远离感光鼓的一侧；具体的，弹性件254a设置于分离接触件250的配合部250c远离感光鼓的一侧，即弹性件254a 也露出于导电端端盖212之外。弹性件254a可以是硅胶块。
成像设备A1工作时，成像设备A1的导电端按压件151与弹性件254a的一端抵接，对弹性件254a施加作用力，该作用力也作用于分离接触件250及整个显影盒200，带动显影盒200从显影辊220与感光鼓分离的位置运动至显影辊220与感光鼓接触的位置；同时，弹性件254a被挤压变形，对分离接触件250产生挤压力，能起到缓冲作用，使显影辊220和感光鼓更好地接触。
作为实施例四的一个变形例，如图17所示，弹性件可以是弹片254d，弹片254d的一端可以与分离接触件250连接，另一端延伸至配合部250c远离感光鼓的一侧，并且弹片254d的另一端与配合部250c不接触，即弹片254d与分离接触件250的配合部250c之间有空隙部分。
成像设备A1工作时，导电端按压件151与弹片254d的另一端抵接，对弹片254d施加作用力，该作用力也作用于分离接触件250及整个显影盒200，带动显影盒200从向靠近感光鼓的方向运动，显影辊220与感光鼓接触；同时，弹片254d受力时发生形变，其另一端向靠近配合部250c的方向形变，两者之间的空隙部分变小或者完全接触，能对分离接触件250产生挤压力，也能起到缓冲作用，使显影辊220和感光鼓更好地接触。弹片254d与分离接触件250可以是一体注塑成型。
本实施例中的分离接触件250可以只有露出于导电端端盖212外的配合部250c。
本实施例的分离组件可以设置于显影框架的一端或两端。
显影盒200的其他结构与实施例一相似，在此不再赘述。
实施例五
本实施例提供一种显影盒200，与实施例一至实施例四不同的是，分离组件包括分离接触件250和弹性件254b。
本实施例中，如图18所示，分离接触件250转动设置于导电端端盖212，能够接收成像设备A1的作用力而在第一位置和第二位置之间运动；即分离接触件250能够以支撑柱2121为中心转动，分离接触件250上设有第一连接块250e，第一连接块250e设置于分离接触件250的连接部250a的一端上，即第一连接块250e和配合部250c分别位于分离接触件250的不同端。
如图18所示，弹性件254b，连接分离接触件250和显影框架，具体的，导电端端盖212内侧设有第二连接块2124，弹性件254b的一端连接分离接触件250上的第一连接块250e，另一端连接第二连接块2124。本实施例中，弹性件254b为拉簧，受力时拉伸形变。当分离接触件250处于第一位置时，显影盒200位于远离感光鼓的位置，显影辊220与感光鼓分离，弹性件254b未被拉伸，当 分离接触件250从第一位置运动到第二位置时，显影辊220与感光鼓相接触，弹性件254b被拉伸形变。
当成像设备A1工作时(打印任务进行时)，成像设备A1中的导电端按压件151沿NH7方向移动，与分离接触件250的配合部250c相抵接，对分离接触件250施加作用力使其从第一位置转动至第二位置的过程中，导电端按压件151的作用力也作用在显影盒200上，显影盒200受力转动，向靠近感光鼓的方向转动，从而使显影辊220与感光鼓接触；同时，在分离接触件250转动的过程中，分离接触件250的配合部250c的一端朝向靠近显影辊220的方向转动，分离接触件250另一端上设置的第一连接块250e则向远离显影辊220的方向转动，使连接与第一连接块250e上的弹性件254b被拉伸。弹性件254b拉伸形变后对分离接触件250产生沿着将分离接触件250从第二位置移动到第一位置的方向的偏压力，偏压力也作用于导电端按压件151，使导电端按压件151也产生与偏压力方向相反的反作用力，反作用力作用于分离接触件250和整个显影盒200，使显影辊220能进一步贴紧感光鼓，也能起到缓冲作用，使显影辊220和感光鼓更好的接触，保证显影质量。
需要说明的是，上述分离组件不限于设置在导电端，也可以设置在驱动端，还可以设置于驱动端和导电端。如图19所示，当设置于驱动端时，分离接触件250设置于驱动端轴承211的外侧，驱动端轴承211的外侧设置第二连接块2124，弹性件254b连接分离接触件250和驱动端轴承211，连接方式与分离组件设于导电端的一致，在此不再赘述。
进一步的，如图18至图20所示，显影框架上还可以设置用于遮挡弹性件254b的肋板2123，分离组件设置于导电端时，导电端端盖212内侧面上设置有肋板2123，肋板2123位于弹性件254b的下方侧，从整个显影盒200外观观察，弹性件254b完全被肋板2123和/或导电端端盖212遮挡(不能被观察到)，如图20所示。肋板2123的设置可以起到保护作用，避免外部件从缝隙进入，对弹性件254b和/或分离接触件250的工作造成干扰。同样的，驱动端轴承211外侧也设置肋板2123。
显影盒200的其他结构与实施例一相似，在此不再赘述。
实施例六
本实施例提供一种显影盒200，与上述实施例相比，分离组件包括分离接触件250和弹性件254c。

如图21和图22所示，弹性件254c，与分离接触件250同轴设于驱动端轴 承211，其一端抵接驱动端轴承211，另一端抵接分离接触件250；具体的，弹性件254c为扭簧，扭簧的圈部套设于驱动端轴承211上的支撑柱2121，且相比于分离接触件250更靠近盒体210。驱动端轴承211上设有固定块2111，扭簧的一端抵接在固定块2111与驱动端轴承211的内侧面之间，扭簧的另一端抵接在分离接触件250上。
当成像设备A1工作时(打印任务进行时)，成像设备A1中的导电端按压件151沿NH7方向移动，与分离接触件250的配合部250c相抵接，对分离接触件250施加作用力使其从第一位置转动至第二位置的过程中，导电端按压件151的作用力也作用在显影盒200上，显影盒200受力转动，向靠近感光鼓的方向转动，从而使显影辊220与感光鼓接触；同时，在分离接触件250转动的过程中，弹性件254c的另一端始终抵在分离接触件250上，并且对分离接触件250产生沿着将分离接触件250从第二位置移动到第一位置的方向的偏压力，偏压力也作用于导电端按压件151，使导电端按压件151也产生与偏压力方向相反的反作用力，反作用力作用于分离接触件250和整个显影盒200，使显影辊220能进一步贴紧感光鼓，也能起到缓冲作用，使显影辊220和感光鼓更好的接触，保证显影质量。
本实施例中，如图22和图23所示，动力接收件231包括联轴器231a、第二弹性件231b和齿轮部231c，齿轮部231c中部设有空腔，联轴器231a设于该空腔内，第二弹性件231b设于空腔内，且第二弹性件231b的两端分别抵接联轴器231a和空腔的底壁。联轴器231a用于与成像设备A1的驱动头啮合，接收驱动力，带动齿轮部231c旋转，齿轮部231c用于与显影辊齿轮、搅拌架齿轮233啮合传递驱动力，从而带动显影辊220和搅拌架工作。第二弹性件231b在联轴器231a与驱动头啮合时能起到缓冲作用，避免联轴器231a和驱动头碰撞损坏。
如图23所示，沿着垂直于显影辊220的旋转轴线的方向观察，第二弹性件231b与弹性件254c不在同一平面上，即第二弹性件231b与弹性件254c在显影辊220的旋转轴线的方向上无重叠部分。弹性件254c相比于第二弹性件231b更靠近盒体210。
需要说明的是，上述分离组件不限于设置在驱动端，也可以设置在导电端，还可以设置于驱动端和导电端。当设置于导电端时，分离接触件250设置于导电端端盖212的内侧，连接方式与分离组件设于驱动端的一致，在此不再赘述。

本实施例中，分离组件包括转动设置于显影框架的分离接触件250和与分离接触件250活动连接的力传递件255。
本实施例中，分离组件设置于显影框架的驱动端，即分离接触件可转动地设置于驱动端轴承211的外侧(远离盒体210的一侧)，分离接触件250能够接收成像设备A1的作用力而在第一位置和第二位置之间运动，分离接触件250的结构与实施例五相同，在此不再赘述。
如图24至图28所示，显影框架上设有导滑槽2112，具体的，导滑槽2112设置于驱动端轴承211的外侧面上，导滑槽2112内设有突起部21121，突起部21121大致位于导滑槽2112的中部位置，将导滑槽2112分为相互连通的第一部分21122和第二部分21123，第一部分21122相较于第二部分21123距离显影辊220更远。
如图24至图28所示，力传递件255为杆状构件，其一端与分离接触件250铰接，另一端与导滑槽2112滑动连接，力传递件255被分离接触件250带动运动时，其另一端沿导滑槽2112滑动。具体的，力传递件255的一端设置有转动部255a，分离接触件250设置有与转动部255a相配合的转动固定部250f，转动部255a可以是开设与力传递件255一端的通孔，转动固定部250f可以是设置于分离接触件250的杆部250b上的支轴，通过支轴与通孔配合以将力传递件255转动设置于分离接触件250上；可选择的，也可以是转动部255a设置为支轴，转动固定部250f设置为通孔，支轴可以是分体或一体设置。力传递件255的另一端设置有滑动部255b，滑动部255b与导滑槽2112滑动连接，滑动部255b可以是柱状件或块状件，其从力传递件255的表面朝向盒体210的方向延伸/突出，装配时，力传递件255朝向盒体210的表面与导滑槽2112背向盒体210的表面抵接，滑动部255b插入到导滑槽2112内，导滑槽2112的第二部分21123靠近显影辊220的一端封闭或部分封闭，第一部分21122远离显影辊220的一端封闭或部分封闭，从而防止滑动部255b沿着导滑槽2112滑动时从导滑槽2112脱出。
滑动部255b能够在成像设备的作用力(具体是驱动端按压件150对分离接触件250的作用力传递至力传递件255使滑动部255b移动)下滑动越过突起部21121，突起部21121能够起到限位作用，使滑动部255b在第一部分21122或第二部分21123内保持稳定。突起部21121可以是弹性的或刚性的。
如图28所示，当成像设备工作时(打印任务进行时)，成像设备中的驱动端按压件150沿NH7方向移动，与分离接触件250的配合部250c远离显影辊220的一侧相抵接，并对分离接触件250施加作用力(推压力)，分离接触件250绕着支撑柱2121逆时针旋转从第一位置运动至第二位置，同时，分离接触件250带动与其活动连接的力传递件255运动，使力传递件255的滑动部255b从导滑 槽2112的第一部分21122越过突起部21121到达第二部分21123，滑动部255b移动至与导滑槽2112靠近显影辊220的一端相抵接，使分离接触件250接收的推压力，通过力传递件255作用于整个显影盒，使得显影盒受力运动，沿着靠近感光鼓的方向运动，从而使显影辊220与感光鼓接触。
如图28所示，当成像设备结束打印后，成像设备中的驱动端按压件150沿NH8方向移动，与分离接触件250的配合部250c靠近显影辊220的一侧相抵接，并对分离接触件250施加作用力(推压力)，分离接触件250沿顺时针旋转从第二位置运动至第一位置，同时，分离接触件250驱动力传递件255运动，使力传递件255的滑动部255b从导滑槽2112的第二部分21123越过突起部21121到达第一部分21122，滑动部255b移动至与导滑槽2112远离显影辊220的一端相抵接，使分离接触件250接收的推压力，通过力传递件255作用于整个显影盒，使得显影盒受力后朝向远离感光鼓的方向运动，从而使显影辊220与感光鼓分离。
需要说明的是，上述分离组件不限于设置在驱动端，也可以设置在导电端，还可以同时设置于驱动端和导电端。当设置于导电端时，分离接触件250和力传递件255设置于导电端端盖212的内侧或者盒体210在导电端的端面上，导电端端盖212内侧或盒体210在导电端的端面上设置支撑柱2121、导滑槽2112等结构，连接方式与分离组件设于驱动端的一致，在此不再赘述。
实施例八
本实施例提供另一种显影盒，与上述实施例相比，不同之处在于分离组件的结构不同。
如图29所示，本实施例中，分离组件包括分离接触件250、第一限制部2113和第二限制部2114，分离接触件250的结构与实施例一相同，均设置于驱动端轴承211上，分离接触件250的连接部250a上设有一突出的凸块250g，用于与第一限制部2113相抵接，第一限制部2113设置于驱动端轴承211的外表面，且位于支撑柱2121的上方侧，第一限制部2113包括沿远离盒体210的方向突出设置的柱部和设置于柱部远离盒体210的一端的圈部，连接部250a上设置向上突出的凸块250g，能够到达与第一限制部2113的圈部相抵的位置，且凸块250g抵接与圈部靠近显影辊220的一侧，圈部受到一定的外力时，能够产生较小程度的形变。第二限制部2114为驱动端轴承211的一部分，第二限制部2114位于分离接触件250远离显影辊220的一侧，且与分离接触件250相抵接。即第一限制部2113和第二限制部2114分别抵接于分离接触件250的不同侧，使得分离接触件250的转动被限制。
当成像设备工作时(打印任务进行时)，成像设备中的驱动端按压件150沿 NH7方向移动，与分离接触件250的配合部250c远离显影辊220的一侧相抵接，并对分离接触件250施加作用力(推压力)，使得分离接触件250具有逆时针旋转的趋势，但由于分离接触件250的凸块250g与第一限制部2113的圈部抵接，使得分离接触件250不能旋转，分离接触件250接收的推压力作用于整个显影盒，使得显影盒受力运动，沿着靠近感光鼓的方向运动，从而使显影辊220与感光鼓接触。此外，分离接触件250对第一限制部2113的推压力，能使第一限制部2113的圈部发生轻微形变，圈部形变的产生的作用力也能反作用于显影盒，能使显影辊220进一步贴近感光鼓，也能起到缓冲作用，使显影辊220和感光鼓更好的接触，保证显影质量。
当成像设备结束打印后，成像设备中的驱动端按压件150沿NH8方向移动，与分离接触件250的配合部250c靠近显影辊220的一侧相抵接，并对分离接触件250施加作用力(推压力)，使得分离接触件250具有顺时针旋转的趋势，但由于分离接触件250与第二限制部2114相抵，使得分离接触件250不能旋转，分离接触件250接收的推压力作用于整个显影盒，使得显影盒受力后朝向远离感光鼓的方向运动，从而使显影辊220与感光鼓分离。
需要说明的是，上述分离组件不限于设置在驱动端，也可以设置在导电端，还可以设置于驱动端和导电端。
本实施例的显影盒的其他结构与实施例一相似，在此不再赘述。
实施例九
本实施例提供又一种显影盒，与上述实施例相比，不同之处是还包括用于保护分离接触件250的护板结构。
如图30所示，为了便于分离接触件250的配合部250c与驱动端按压件150配合，配合部250c突出于盒体210设置，因此，在运输的过程中，分离接触件250的配合部250c容易收到冲击、碰撞损坏，甚至使整个分离接触件250都受损，影响分离组件的功能，因此，设置护板结构保护分离接触件250防止在运输过程中力承受部件破损，影响显影盒质量。
具体的，如图30所示，护板结构包括分别位于分离接触件250的两侧的第一护板261和第二护板262，第一护板261和第二护板262可以是长方形板状件，第一护板261可以设置与驱动端盖213的下边缘，第二护板262可以设置于驱动端轴承211的下边缘，第一护板261和第二护板262在盒体210的长度方向上相对设置，力接收件的配合部250c位于第一护板261和第二护板262之间，且在高度方向上，分离接触件250不突出于护板结构，分离接触件250完全被第一护板261和第二护板262遮盖，从而得到保护作用，防止分离接触件250在运输过程中受损。使用时，驱动端按压件150从第一护板261和第二护板262 之间与配合部250c接触，且驱动端按压件150的移动方向以及力接收件的运动方向均垂直于盒体210的长度方向，护板结构不会产生阻碍，分离组件能够正常实现其功能。
需要说明的是，当分离组件设置在导电端时，可以在导电端端盖212和盒体210上相对设置护板结构，当分离组件设置于驱动端和导电端时，护板结构同时设置于驱动端和导电端。
实施例十
当显影盒装机到成像设备上准备显影工作的过程中，通常需要通过成像设备与显影盒之间的配合进行装机检测，保证显影盒安装至正确位置以使成像设备正常进行显影工作，有的成像设备则是通过装机检测来识别显影盒的相关信息(例如容量大小、颜色、型号等)，因此，若装机检测装置不稳定则会导致显影盒无法正常使用。
如图31和图32所示，本实施例提供一种显影盒，与上述实施例相比，还包括被检测组件，用于与成像设备配合以完成显影盒的装机检测。成像设备(未示出)还设有装机检测装置(未示出)，其中装机检测装置包括摆动引导件(未示出)，摆动引导件通过连接杆安装在成像设备内，且摆动引导件能够以连接杆为中心在成像设备内进行摆动，在显影盒安装在成像设备时，显影盒与摆动引导件配合，带动摆动引导件摆动并与成像设备的其他结构配合，共同完成显影盒的装机检测。
如图31至图34所示，被检测组件包括被检测件270和旋转件260，旋转件260能够在驱动组件的驱动下旋转；被检测件270直接或间接地被所述旋转件260驱动从而触发成像设备内的摆动引导件。
如图31和图32所示，本实施例中，驱动组件设置于盒体210外侧与驱动端盖213之间，驱动组件包括动力接收件231、显影辊齿轮、第一传动齿轮234和第二传动齿轮235。动力接收件231用于接收成像设备A1的驱动力将驱动力传递，进而带动显影辊220和搅拌架旋转并能够驱动被检测组件运行。显影辊齿轮固定在显影辊220的轴在长度方向上的一端，显影辊齿轮与动力接收件231的齿轮部啮合，从而使显影辊220能够接收驱动力旋转。第一传动齿轮234可旋转地支撑在盒体210的驱动端，第一传动齿轮234为二阶同轴齿轮，包括同轴设置的大齿轮部和小齿轮部，大齿轮部相较于小齿轮部离盒体210更远，大齿轮部与动力接收件231的齿轮部相啮合，小齿轮部与第二欢动齿轮相啮合，即动力接收件231接收成像设备的驱动力旋转时，带动第一传动齿轮234旋转，第一传动齿轮234旋转再带动第二传动齿轮235旋转。第二传动齿轮235连接在搅拌架在长度方向上的一端，即第二传动齿轮235旋转时，能带动搅拌架同 步旋转，即第二传动齿轮235也被称为搅拌架齿轮。
如图31、图32和图38所示，旋转件260为可旋转地支撑在盒体210驱动端外侧的齿轮构件，旋转件260包括齿牙部261、缺齿部262和突出部263，齿牙部261设置在旋转件260的外圆周表面上，齿牙部261能与第二传动齿轮235啮合，使旋转件260能够被第二传动齿轮235驱动。齿牙部261并未完整覆盖旋转件260的外圆周表面，旋转件260的外圆周表面上设有无齿牙部261分，即为缺齿部262，当旋转件260旋转至缺齿部262与第二传动齿轮235相对时，齿牙部261与第二传动齿轮235脱离啮合，旋转件260不能再被第二传动齿轮235驱动。
如图32和图38所示，突出部263设置在旋转件260背向盒体210的端面上，突出部263的数量为至少一个，本实施例中，突出部263设置为三个，且三个突出部263在旋转件260的端面上呈环形阵列排布。突出部263在旋转件260旋转时能够触碰并驱动被检测件270运动。
如图31、图33至图37所示，被检测件270活动设置于驱动端盖213上，被检测件270为滑块，驱动端盖213上设有滑槽2131，滑槽2131为贯穿驱动端盖213内外侧的通槽，被检测件270至少部分嵌入到滑槽2131中，使被检测件270能够在滑槽2131内滑移，且被检测件270至少部分突出且暴露在驱动端盖213的外侧面之外，便于被检测件270运动时触发成像设备内的摆动引导件。滑槽2131大致为弧形槽，即被检测件270滑动的轨迹也为弧形。滑槽2131的延伸方向大致沿盒体210的宽度方向。
进一步的，如图35至图37所示，驱动端盖213的外侧面上还设有限位槽2132，被检测件270上设有与限位柱271，被检测件270安装在滑槽2131内时，限位柱271至少部分嵌入到限位槽2132内，被检测件270在滑槽2131内滑移时，限位柱271也在限位槽2132内滑移，设置限位柱271与限位槽2132的配合，能够对被检测件270进行限位，使被检测件270滑移时更加稳定。
如图34、图36至图38所示，被检测件270朝向旋转件260的一侧设有抵接部272，用于与旋转件260上的突出部263相配合，使得旋转件260旋转时，突出部263能够抵接在抵接部272上，并对抵接部272施加推力，进而使被检测件270被带动沿滑槽2131滑移以触碰摆动引导件。旋转件260上的每个突出部263均能带动被检测件270滑移一次，本实施例中，突出部263设置为三个，即可以驱动被检测件270滑移三次。
如图34所示，被检测件270每次被突出部263带动滑移后，均需要复位至初始位置，便于下一个突出部263能够触碰到抵接部272。被检测组件还包括用于使被检测件270复位的复位件280，复位件280连接在被检测件270和驱动端盖213之间，被检测件270被突出部263驱动滑移时，复位件280弹性形变， 存储弹性势能。当突出部263旋转越过抵接部272后，突出部263对抵接部272的推力消失，复位件280形变恢复释放弹性势能，带动被检测件270沿相反的方向滑移复位至初始位置，等待下一个突出部263旋转到位后再次被驱动。具体的，复位件280为拉伸弹簧，驱动端盖213上设有第一弹性挂钩部2133，被检测件270上设有第二弹性挂钩部273，复位件280的一端连接在第一弹性挂钩部2133上，另一端连接在第二弹性挂钩部273上。可选择的，复位件280还可以是压缩弹簧、弹性橡胶、弹性海绵、弹簧片等能够提供弹性恢复力的部件，还可以是其他采用非弹性力的结构。
如图31至图38所示，显影盒安装到成像设备后，显影盒部分进行装机检测的工作过程如下：
显影盒安装至成像设备中，成像设备中的驱动头与动力接收件231接合，驱动头旋转带动动力接收件231旋转，并将驱动力传递至第一传动齿轮234、第二传动齿轮235及旋转件260，旋转件260旋转的过程中，突出部263与被检测件270上的抵接部272抵接，并对其施加推力，推动被检测件270在滑槽2131内滑动，被检测件270滑动时触碰成像设备内的摆动引导件并使之摆动；被检测件270滑动的同时，带动复位件280使之产生形变，随着旋转件260继续旋转，突出部263转过与抵接部272抵接的位置，对被检测件270的推力消失，被检测件270在复位件280的弹性恢复力作用下复位至初始位置；旋转件260旋转至下一个突出部263与抵接部272抵接时，重复上述过程。由于本实施例中旋转件260上的突出部263设置为三个，因此，突出部263将推动被检测件270三次，成像设备的摆动引导件也被触发三次，成像设备识别到三次摆动引导件运动时产生的信号即判断为装机检测完成。
旋转件260被第二传动齿轮235带动旋转过齿牙部261的行程后，到达缺齿部262与第二传动齿轮235相对的位置，齿牙部261与第二传动齿轮235脱离啮合，此后，第二传动齿轮235旋转无法再驱动旋转件260旋转。
本实施例的显影盒设置被检测组件，可以直接或间接地接收成像设备的驱动力运行，旋转件260在手驱动的过程中带动被检测件270运动，以配合成像设备的装机检测装置(包括摆动引导件)完成装机检测，结构简单、使用稳定，能更好地进行显影盒装机检测。
在一些其他实施方式中，旋转件260上的突出部263的数量可以设置得更多或更少，还可以改变突出部263之间的间距、弧长等，进而改变被动引导件被触发的次数、触碰间隔、触碰时长等，从而使成像设备可以识别不同型号、容量、寿命的显影盒。
在一些其他的实施方式中，被检测组件也可以设置于显影盒的导电端，还可以同时设置于显影盒的驱动端和导电端。
以上所述的仅是本发明的一些实施方式。对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
