下面根据本申请实施例提供的图像形成装置的结构，对其具体实施例进行说明。
请参阅图1至图9，本申请提供一种图像形成装置100，其包括处理盒1、封膜滑块3及本体2，处理盒1上设置有用于容纳碳粉的粉仓10，粉仓10设置有出粉口11，粉仓10设置出粉口11的壁上活动设置有密封膜12，密封膜12上设置有出粉孔121。封膜滑块3滑动设置于处理盒1上，封膜滑块3与密封膜12连接。本体2设置有用于收容处理盒1的收容槽21及设置于收容槽21开口处的挡块22。密封膜12至少具有密封状态及连通状态，当密封膜12处于密封状态时，出粉孔121与出粉口11不重叠，密封膜12将出粉口11密封；当密封膜12处于连通状态时，出粉孔121与出粉口11连通；在多个处理盒1插入收容槽21的过程中，挡块22依次与每个处理盒1上的封膜滑块3接触并带动封膜滑块3运动，以 使封膜滑块3带动密封膜12从密封状态切换至连通状态。
图像形成装置100可以是激光打印机、复印机、复合机等具备打印功能的产品。
处理盒1包括显影单元和感光鼓单元，显影单元又包括显影仓和粉仓10。粉仓10用于容纳碳粉(也叫显影剂)，其上设置有出粉口11，粉仓10内的碳粉通过出粉口11到达显影仓，从而被传送到位于显影仓的显影辊上。
密封膜12可以是条带状结构，其至少部分贴合于粉仓10的出粉口11上以将其密封，密封膜12活动设置于粉仓10的底壁上，具体地，密封膜12可以滑动设置于粉仓10的底壁也可以转动设置于粉仓10的底壁上，只要使得密封膜12能相对粉仓10上的出粉口11做相对运动即可。密封膜12上还设置有出粉孔121，出粉孔121的形状、大小及数量可以与出粉口11相匹配。密封膜12至少具有密封状态及连通状态，当处理盒1未塞入本体2时，密封膜12处于密封状态，此时出粉孔121与出粉口11不重叠，密封膜12的主体部分将出粉口11密封。在多个处理盒1塞入本体2的过程中，挡块22依次与每个处理盒1上的封膜滑块3接触并带动封膜滑块3运动，进而带动与之连接的密封膜12运动，以使密封膜12相对粉仓10上的出粉口11运动，直至出粉孔121与出粉口11连通，此时粉仓10内的碳粉即可沿出粉口11进入显影仓。。
封膜滑块3滑动设置于粉仓10上，粉仓10上可以设置常见的滑槽结构来限制封膜滑块3的运动轨迹，在某些实施例中，封膜滑块3可以在滑槽的限制下沿粉仓10的长度方向运动。
本体2上设置有收容槽21，处理盒1能沿收容槽21的开口方向塞入收容槽21内，以处理盒1塞入收容槽21时运动的方向为第一方向41，则封膜滑块3沿与第一方向41交叉的第二方向42滑动设置于处理盒1上，在某些实施例中，第一方向41与第二方向42垂直。请参阅图2，收容槽21的开口处设置有挡块22，挡块22上设置有与第一方向41交叉的斜面，在多个处理盒1沿第一方向41运动的过程中，挡块22上的斜面与封膜滑块3接触，并提供一推动封膜滑块3沿第二方向42运动的力，以使封膜滑块3运动并带动密封膜12从密封状态切换至连通状态。
在其中一个实施例中，粉仓10的底壁上设置有多个出粉口11，密封膜12上设置有多个出粉孔121，出粉口11与出粉孔121一一对应设置，每一出粉口11和与之对应的出粉孔121的形状、大小可以相同，也可以不同。
请参阅图3、图4及图5，当设置多个出粉口11与出粉孔121时，各个出粉口11可以成排设置，各个出粉孔121同样成排设置，且出粉孔121的形状、大小与对应的出粉口11相同，相邻出粉口11之间的间距和相邻出粉孔121之间的间距也相同，如此，在密封膜12从密封状态切换至连通状态时，密封膜12上的出粉孔121能一一对应于出粉口11上，以使粉仓10内的碳粉能快速、大量地排出，提高了供粉效率及均匀性。
在其中一个实施例中，粉仓10设置有出粉口11的侧壁上还设置有封膜安装槽101，密封膜12滑动设置于封膜安装槽101内。
请参阅图4及图5，封膜安装槽101可以是沿密封膜12的滑动方向延伸设置的两个滑槽，两个滑槽分别设置于密封膜12的两侧，密封膜12的侧边分别收容于两个滑槽内，如此，提高了密封膜12的滑动稳定性，且限制了密封膜12的滑动轨迹，进而保证密封 膜12从密封状态切换至连通状态时，密封膜12上的出粉孔121能一一对应于出粉口11上。
在其中一个实施例中，粉仓10还包括封膜压板13，请参阅图6，封膜压板13设置于粉仓10的底壁面，封膜压板13与粉仓10的底壁面将密封膜12夹设其间。
封膜压板13可以是平板结构，其大小至少能够覆盖粉仓10上开设有出粉口11部分的全部范围。封膜压板13设置有孔洞结构，在密封膜处于连通状态时，该孔洞结构与密封膜12上的出粉孔以及出粉口11一一对应。粉仓10的底壁面上可以设置定位元件，例如定位柱等，封膜压板13上可以开设相匹配的定位孔。封膜压板13通过定位柱与定位孔之间的配合固定于粉仓10的底壁面，而密封膜12则被封膜压板13与粉仓10的底壁面包夹，如此，进一步限制了密封膜12的活动范围，提高了密封膜12运动的稳定性。
在其中一个实施例中，粉仓10包括底壁14、顶壁15及连接二者的侧壁16，出粉口11设置于底壁14，封膜滑块3设置于顶壁15，密封膜12依次经过底壁14、侧壁16及顶壁15并与封膜滑块3连接。
请参阅图3，底壁14与顶壁15相对设置，侧壁16将二者连接起来，粉仓10大致呈方形体结构，出粉口11设置于底壁14，以便于排粉，封膜滑块3设置于顶壁15，便于观察密封滑销的动作状态。密封膜12贴合于处理盒1上，密封膜12的一端设置于底壁14，粉仓10的一端设置有封膜出口102，密封膜12的剩余部分穿过粉仓10的封膜出口102依次经过侧壁16及顶壁15并与封膜滑块3连接。如此，在推动处理盒1进入收容槽21的过程中，处理盒1的顶壁15可以朝上设置，便于观察密封滑销的动作状态，当密封滑销经过挡块22的推动后，密封膜12处于连通状态，粉仓10内的碳粉经出粉口11进入显影仓。
在其中一个实施例中，所述粉仓1还包括封膜密封塞18，请参阅图7，所述封膜密封塞18设置于所述封膜出口102靠近侧壁16的一侧，且所述封膜密封塞18与所述封膜密封轴靠近所述底壁14的一侧抵接。进而保证密封膜12在拉动过程中不会有碳粉被拉出。
在其中一个实施例中，粉仓1上转动设置有封膜转轴17，封膜转轴17设置于底壁14与侧壁16的连接处，用于引导密封膜12。
请参阅图7，因为粉仓1上侧壁16与底壁14之间存在转角，密封膜12在转角处收到的摩擦力较大，在拉动使容易受力不均导致破损，所以本方案在底壁14与侧壁16的连接处设置了封膜转轴17，封膜转轴17的转动轴向与密封膜12的运动方向垂直，所以绕设于封膜转轴17上的密封膜12能够带动封膜转轴17转动，从而降低密封膜12上的应力。密封膜12的一端穿过粉仓10的封膜出口102，被封膜转轴17支撑绕至顶壁15，与封膜滑块3固定。
在其中一个实施例中，封膜滑块3包括固定轴31及转动连接于固定轴31上的转动部32，固定轴31与密封膜12连接，当挡块22驱动封膜滑块3运动时，转动部在挡块22的驱动下转动。
请参阅图2，本方案在固定轴31上设置转动部32，使得挡块22驱动封膜滑块3运动时转动部32能绕固定轴31转动，如此，减小了挡块22与封膜滑块3之间的摩擦阻力，提高了二者接触后运动过程中的顺滑程度。
在其中一个实施例中，本体2还包括抽屉23，抽屉23沿收容槽21的开口方向滑动设 置于收容槽21内，抽屉23上并排设置有多个处理盒1，在抽屉23收入收容槽21的过程中，每一处理盒1上的封膜滑块3依次被挡块22推动，以使封膜滑块3带动密封膜12从密封状态切换至连通状态。
请参阅图1，抽屉23可在外力作用下沿第一方向41塞入本体2的容纳槽，图像形成装置100的本体2上设置有挡块22，当处理盒1安装在抽屉23内，抽屉23在外力作用下沿第一方向41推入容纳槽的过程中，设置在图像形成装置100本体2上的挡块22依次与多个处理盒1上的封膜滑块3接触，每个处理盒1上的封膜滑块3在挡块22的作用下移动，从而带动密封膜12移动一定的距离，使密封膜12上的出粉孔121与出粉口11重合。因为抽屉23中并排设置有多个处理盒1，且各个处理盒1上的封膜滑块3处于同一连线上，所以在推动抽屉23进入容纳槽的过程中，可以在一次推动操作中拉开多个处理盒1的密封膜12，提高了操作效率。
在其中一个实施例中，挡块22上设置有接触斜面221，在处理盒1向进入收容槽21的方向运动的过程中，接触斜面221能够与封膜滑块3接触并推动其沿垂直于处理盒1运动的方向移动。
请参阅图1，挡块22上的接触斜面221使得挡块22在第一方向41上形成锥形结构，其尖端位于收容槽21靠近外部一侧，其大端位于收容槽21靠近内部一侧，在处理盒1向进入收容槽21的方向运动的过程中，封膜滑块3与尖端一侧接触后继续向靠近收容槽21的方向运动，封膜滑块3在接触斜面221的作用下沿与第一方向41交叉的方向运动，以使密封膜12从密封状态切换至连通状态。
在其中一个实施例中，挡块22转动设置于本体2上，且挡块22能在第一极限位置与第二极限位置之间转动，当挡块22处于第一极限位置时，在处理盒1在进入收容槽21的过程中，挡块22能够与封膜滑块3接触并带动封膜滑块3运动；
当挡块22处于第二极限位置时，在处理盒1从收容槽21抽出的过程中，挡块22与封膜滑块3不接触。
请参阅图8及图9，挡块22转动设置于本体2上，挡块22能在第一极限位置与第二极限位置之间转动，当挡块22处于第一极限位置时，挡块22悬置于收容槽21的开口处。在处理盒1沿第一方向41运动进入收容槽21的过程中，封膜滑块3沿第一方向41运动并与挡块22接触，挡块22保持在第一极限位置不动，封膜滑块3在挡块22的作用下带动密封膜12运动。
在处理盒1从收容槽21内抽出的过程中，封膜滑块3与挡块22靠近收容槽21的一面接触并推动挡块22由第一极限位置转动至第二极限位置，以使挡块22从封膜滑块3的运动路径上避开，从而保证抽屉23能顺利从收容槽21内抽出。
综上，本申请提供的图像形成装置能够利用挡块与封膜滑块之间的配合关系，使得处理盒在插入收容槽的过程中，挡块能与封膜滑块接触并带动封膜滑块运动，以使封膜滑块带动密封膜从密封状态切换至连通状态。使得撕密封膜的操作和安装处理盒的操作合并为一个操作步骤，提高了操作的便利性；而且在处理盒插入收容槽时，挡块同步推动封膜滑块运动以打开密封膜，避免了手工撕密封膜带来的碳粉泄漏及污染环境的问题，提高了用户的使用感受。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
