本申请要求在2021年09月13日提交中国专利局、申请号为202111070829.5、申请名称为“一种墨粉盒及激光打印机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及打印机技术领域，尤其涉及到一种墨粉盒及激光打印机。
背景技术
激光打印机是将激光扫描技术和电子照相技术相结合的打印输出设备，具有打印速度快、成像质量高等优点。激光打印机中使用的硒鼓与墨粉盒一般为一体式设计或者分离式设计，对于采用一体式设计的硒鼓与墨粉盒，用户在更换墨粉盒时需要连同硒鼓一起整体更换，更换成本较高，且用户在更换过程中，会触碰打印机内部结构，导致操作体验较差。而对于采用分离式设计的硒鼓与墨粉盒，尽管硒鼓与墨粉盒可相对独立，但是在更换墨粉盒时往往也需要将硒鼓与墨粉盒的整体组装结构从打印机内取出，然后将墨粉用尽的墨粉盒从硒鼓上拆下后装上新的墨粉盒，再将硒鼓与墨粉盒的整体组装结构装入打印机内，更换过程较为繁琐，操作性较差。
发明内容
本申请提供了一种墨粉盒及激光打印机，用以提高墨粉盒的使用可靠性，以及降低激光打印机更换墨粉盒的成本。
第一方面，本申请提供了一种墨粉盒，该墨粉盒可包括盒体、粉仓、第一搅拌辊、第一仓门、第一卡勾以及手柄。其中，盒体可包括位置相对的第一侧和第二侧，盒体的第一侧可设置有开孔，盒体的第二侧可设置有窗口。粉仓可设置于盒体内，用于容置墨粉，粉仓朝向窗口的位置设置有可暴露于窗口内的补给口。第一搅拌辊可设置于粉仓内，用于将粉仓内的墨粉输送到补给口的位置。第一仓门可滑动装配在粉仓朝向窗口的一侧，第一仓门上可设置有卡槽，第一仓门可在滑动时将补给口打开或者关闭。第一卡勾可设置于盒体的第二侧，第一卡勾可用于在第一仓门将补给口关闭时与卡槽卡接。手柄可滑动设置在粉仓背向窗口的一侧，手柄可穿过开孔暴露在盒体的外侧，且手柄可与第一仓门固定连接。
上述方案中，墨粉盒的粉仓补给口可通过第一仓门锁定，从而可避免粉仓内的墨粉泄露，提高墨粉盒的使用可靠性。另外，由于墨粉盒内未设置感光鼓与显影辊等部件，因此对于激光打印机来说更换墨粉盒的成本较小。
在一些可能的实施方案中，第一卡勾可设置在第一仓门朝向粉仓的一侧，这样，第一卡勾在受到外力作用时可缩回至盒体内侧将第一仓门解锁，从而将补给口打开。
在一些可能的实施方案中，第一搅拌棍包括转轴以及固定于转轴上的多个叶片，多个叶片可呈螺旋状沿转轴的轴向设置，当转轴转动时，叶片能够带动粉仓内的墨粉产生螺旋 运动，将墨粉向补给口处输送。
示例性地，叶片可以为弓形结构，叶片的圆弧段靠近粉仓的内壁设置，从而与粉仓的内壁形状能够更好地匹配，进而实现对墨粉的充分搅拌。
在一些可能的实施方案中，相邻的两个叶片之间的夹角可以在75°～90°之间。
在一些可能的实施方案中，叶片上可设置有第一刮片，第一刮片为柔性材质，第一刮片的端部超出叶片背离转轴的一侧并与粉仓的内壁接触。当转轴转动时，第一刮片的端部可以与粉仓的内壁接触摩擦，从而可以保证墨粉能够被充分搅拌，另外由于第一刮片为柔性材质，因此还可以减小第一刮片与粉仓的内壁的摩擦力，进而减小第一搅拌辊的扭矩，降低墨粉盒向硒鼓组件输送墨粉的负载。
在一些可能的实施方案中，转轴对应补给口的位置还可以设置有第二刮片，第二刮片的端部可与粉仓的内壁接触。在转轴转动时，第二刮片可以将粉仓内补给口处的墨粉传送至粉仓的外部，从而提高墨粉的输送效率。
示例性地，第二刮片也可以为柔性材质，这样第二刮片的端部也可以与粉仓的内壁接触摩擦，从而使得补给口处的墨粉能够被充分搅拌。
具体设置时，第二刮片的数量可以为两个，两个第二刮片可相对转轴呈中心对称设置，从而进一步提高墨粉的输送效率。
在一些可能的实施方案中，手柄可包括第一滑轨、手柄本体和连接臂，其中，第一滑轨可设置在粉仓背离窗口的一侧，手柄本体滑动装配在第一滑轨上，连接臂可穿过粉仓与盒体的内壁之间的缝隙与第一仓门固定连接，从而当用户滑动手柄本体时能够带动第一仓门同步滑动，将补给口打开或关闭。
在一些可能的实施方案中，粉仓朝向窗口的一侧可设置有第二滑轨，第一仓门可滑动装配在第二滑轨上。沿盒体的第一侧指向其第二侧的方向，连接臂和第一仓门的连接位置与第二滑轨之间的距离可不大于2mm。连接臂和第一仓门的连接位置与第二滑轨之间的距离即为第一仓门的受力点与第二滑轨之间的距离，该距离越小，第一仓门所受到的偏转力矩也就越小，第一仓门在第二滑轨上也就可以更加平稳地滑动。
在一些可能的实施方案中，第一仓门上可设置有第一开口，当第一仓门滑动至第一开口与补给口位置相对时，第一仓门可将补给口打开，当第一仓门滑动至第一开口与补给口位置相错时，第一仓门可将补给口关闭。
第二方面本申请还提供了一种激光打印机，该激光打印机可包括壳体、硒鼓组件以及前述任一可能的实施方案中的墨粉盒。其中，壳体的侧面设置有安装孔，硒鼓组件设置于壳体内，硒鼓组件可包括仓体，仓体的一侧对应安装孔的位置设置有容置槽，该容置槽的底部设置有与仓体内部连通的进粉口。墨粉盒可通过安装孔装配进容置槽内，墨粉盒的补给口与进粉口位置相对，从而可以在补给口打开时将墨粉输送到硒鼓组件。
上述方案中，墨粉盒与硒鼓组件相互独立设置，使得激光打印机可以实现单独更换墨粉盒，更换步骤较为简单，墨粉盒与硒鼓组件沿激光打印机的横向方向排布，相比于现有技术中墨粉盒与硒鼓组件竖直叠置的方式，有助于缩小激光打印机的高度尺寸。在更换墨粉盒时，只需在激光打印机侧面的安装孔内取出及安装墨粉盒，无需打开激光打印机上盖，用户操作时不会看到除硒鼓组件之外的打印机内部零部件，因此有助于提升用户的使用体验。
在一些可能的实施方案中，硒鼓组件还可以包括第二仓门，第二仓门滑动设置在容置 槽的底部，且第二仓门可在滑动时将进粉口打开或者关闭。第二仓门朝向墨粉盒的一侧设置有凸筋，该凸筋可在墨粉盒安装于容置槽内时插入第一仓门的卡槽内，这时第一卡勾在受到凸筋的挤压后变形并回退到盒体的内侧，从而接触对第一仓门的锁定。当第一仓门在手柄的带动下滑动时，基于凸筋与卡槽的卡接配合，第二仓门也会随同第一仓门同步滑动，从而在第一仓门将补给口打开时，第二仓门也能够将进粉口打开，使墨粉盒与硒鼓组件内部之间的通路连通。
在一些可能的实施方案中，第二仓门可设置有第二开口，当第二仓门滑动至第二开口与进粉口位置相对时，第二仓门可将进粉口打开，当第二仓门滑动至第二开口与进粉口位置相错时，第二仓门可将进粉口关闭。
在一些可能的实施方案中，容置槽的底壁可设置有第二卡勾，该第二卡勾可包括弹性臂以及卡勾本体和凸起部，卡勾本体和凸起部均可设置于弹性臂朝向墨粉盒的一侧，卡勾本体可用于在第二仓门将进粉口关闭时与第二开口卡接。当墨粉盒安装于容置槽内时，盒体的第二侧的外壁可挤压凸起部，使弹性臂朝向远离墨粉盒的一侧弯曲，从而带动卡勾本体也同方向弯曲，进而可以解除第二卡勾对第二仓门的锁定，使第二仓门可以随同第一仓门同步滑动。
在一些可能的实施方案中，容置槽的底部可设置有限位臂，该限位臂与容置槽的底部之间具有间隙。当第一仓门朝向将补给口打开的方向滑动时，第一仓门可插接在限位臂与容置槽的底部之间的间隙内，从而利用限位臂在墨粉盒与容置槽的插接方向对墨粉盒进行限位，避免墨粉盒在激光打印机工作过程中松动或者掉落。
在一些可能的实施方案中，容置槽的侧壁可设置有导向滑槽以及扭簧，其中，导向滑槽可沿容置槽的深度方向延伸，扭簧的一端可与仓体固定连接，另一端具有弯曲部，该弯曲部可与导向滑槽的底部之间形成限位空间。盒体的端部设置有与导向滑槽配合的限位轴，在将墨粉盒安装进容置槽内时，限位轴可被弯曲部限定在限位空间内。采用这种设计，一方面可以使用户较为容易地辨认墨粉盒是否安装到位，另一方面弯曲部也可以施加给限位轴一定的抵接力，使墨粉盒可以更稳定地固定在容置槽内。
在一些可能的实施方案中，第一搅拌辊的转轴的一端可设置有第一齿轮，硒鼓组件还可以包括驱动电机和齿轮组，驱动电机可通过齿轮组与第一齿轮传动连接，从而将驱动力通过齿轮组传递给第一齿轮。
示例性地，第一齿轮可设置于粉仓的端部与盒体的内部之间。硒鼓组件还可以包括齿轮轴，齿轮轴的一端位于仓体的内部，另一端可由容置槽的端部伸入容置槽内。齿轮轴位于容置槽内的一端设置有第二齿轮，当墨粉盒安装到位后，第二齿轮可自动与第二齿轮啮合。齿轮轴位于仓体内的一端设置有第三齿轮，第三齿轮与齿轮组传动连接，从而使得驱动电机输出的驱动能够依次通过齿轮组和齿轮轴传递给第一搅拌辊。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
激光打印机是将激光扫描技术和电子照相技术相结合的打印输出设备，具有打印速度快、成像质量高等优点。激光打印机的基本工作原理是接收由计算机传来的二进制数据信息，通过视频控制器转换成视频信号，再由视频接口或者控制系统把视频信号转换为激光驱动信号，然后由激光扫描系统产生载有字符信息的激光束，最后由电子照相系统使激光束成像并转印到纸上。
在激光打印机中，70％的成像部件集中在硒鼓中，打印质量的好坏在很大程度上是由硒鼓决定的。硒鼓通常包括感光鼓、显影辊和墨粉盒几部分，其中，墨粉盒是用于向激光打印机提供墨粉的结构，属于激光打印机中的耗材产品，当墨粉盒内的墨粉用尽时，就需要及时更换，以保证激光打印机的打印效果。
当前，激光打印机中使用的硒鼓与墨粉盒一般采用鼓粉一体式设计或者鼓粉分离式设计，其中，鼓粉一体式设计的打印机是将硒鼓和墨粉盒集成在同一装置上，用户在更换墨粉盒时需要连同硒鼓一起整体更换，更换成本较高，且用户在更换过程中，会触碰打印机内部结构，导致操作体验较差。而采用鼓粉分离式设计的打印机，用户在更换墨粉盒时通 常也需要将硒鼓整体从打印机内取出，然后将墨粉用尽的墨粉盒从硒鼓上拆下后装上新的墨粉盒，再将硒鼓整体装入打印机内，更换过程较为繁琐，操作性较差。
有鉴于此，本申请实施例提供了一种墨粉盒以及包括该墨粉盒的激光打印机，以实现在无需取出硒鼓的前提下对墨粉盒进行单独更换，并简化更换过程，降低更换成本。
图1为本申请实施例提供的激光打印机的局部结构示意图，图2为图1中所示的激光打印机的内部部分结构示意图。一并参考图1和图2所示，本申请实施例所提供的激光打印机1可包括壳体100、硒鼓组件200和墨粉盒300，硒鼓组件200和墨粉盒300设置于壳体100内，且两者之间可拆卸连接。具体实施时，硒鼓组件200可设置有容置槽211，壳体100的侧面对应容置槽211的位置设置有安装孔110，用户可将墨粉盒300可由安装孔110装配进容置槽211内，以使墨粉盒300向硒鼓组件200内部输送墨粉。由于安装孔110只与硒鼓组件200的容置槽211连通，因此用户在安装墨粉盒300的过程中不会看到硒鼓组件200以外的激光打印机1内部零部件，整体操作体验性较好。壳体100的侧面可设置有盖板120，盖板120可通过铰链等结构铰接在壳体100上，当用户更换墨粉盒300时，可将盖板120打开，以暴露出安装孔110，在更换完毕后再将盖板120合上，以将安装孔110及墨粉盒300遮蔽，从而有助于提升激光打印机1的外观质量。另外，尽管图中未示出，激光打印机1还可以包括激光器、声光调制器、高频驱动、扫描器、同步器及光偏转器等装置，这些装置为激光打印机1中公知且常规的功能部件，在此其具体结构设置形式不予赘述。
图3为本申请实施例提供的墨粉盒的分解结构示意图。参考图3所示，本申请实施例所提供的墨粉盒300可以包括盒体310、手柄320、粉仓330、第一搅拌棍340以及第一仓门350。其中，盒体310可以包括具有容纳腔的前壳311以及盖体312，盖体312与前壳311可拆卸连接，以将上述容纳腔封闭。粉仓330收纳于盒体310的容纳腔内，可用于容置墨粉。第一搅拌棍340则设置于粉仓330内，第一搅拌辊340可用于搅拌墨粉，并将墨粉输送至粉仓330内的特定位置。
图4为本申请实施例提供的墨粉盒的局部平面结构示意图。一并参考图3和图4所示，粉仓330朝向盖体312的一侧可设置有补给口331，补给口331可将粉仓330的内部与外部连通。具体设置时，补给口331可靠近粉仓330沿其长度方向的其中一端设置，例如靠近粉仓330的第一端332设置。补给口331的截面形状不限，例如可以为图4中所示的矩形形状。当然，在其它实施方式中，补给口331的截面形状还可以为圆形、椭圆形或者其它规则或不规则的形状，此处不过多赘述。相应地，盖体312上对应该补给口331的位置可设置有窗口3121，窗口3121的截面形状也可以为矩形、圆形等等，本申请对此同样不做限制。窗口3121的横截面积可大于补给口331的横截面积，以将补给口331完全暴露，这时，粉仓330内的墨粉就可通过补给口331和窗口3121被输送至硒鼓组件。可以理解的，墨粉盒300向硒鼓组件输送墨粉的速度与补给口331的面积相关，本实施例中，补给口331的面积可不小于55mm 2，以保证激光打印机工作时的墨粉供应量。
图5为本申请实施例提供的第一搅拌棍的结构示意图。一并参考图4和图5所示，第一搅拌棍340可包括转轴341以及设置于转轴341上的叶片342。在一些实施例中，转轴341上可间隔设置有多个叶片342，沿转轴341的轴向，多个叶片342可大致呈螺旋状排布，从而当转轴341旋转时，叶片342能够带动粉仓330内的墨粉产生螺旋运动，将粉仓330内的墨粉由其一端向另一端输送。可以理解的，粉仓330内墨粉的输送方向可由转轴 341的旋转方向决定，以图4中所示的第一搅拌辊340为例，当转轴341顺时针方向转动时，由粉仓330的第二端333指向其第一端332的方向，叶片342的排布呈螺旋上升的趋势，从而可以将墨粉由粉仓330的第二端333向第一端332输送，进而将墨粉运载至第一端332的补给口331处。
叶片342的材质不限，例如可以为塑胶。另外，叶片342可以采用弓形结构，这时，叶片342的直线段可与转轴341固定连接，叶片342的圆弧段靠近粉仓330的内壁设置，从而与粉仓330的内壁形状能够更好地匹配，进而实现对墨粉的充分搅拌。示例性地，叶片342具体可以为半圆形结构。
图6为本申请实施例提供的墨粉盒的局部结构侧视图。一并参考图5和图6所示，在一些实施例中，转轴341可以包括第一固定板3411和第二固定板3412，第一固定板3411和第二固定板3412分别沿转轴341的轴向方向延伸，两者可垂直交叉设置，这时，转轴341的横截面形状大致为十字形结构。多个叶片342均可设置于第一固定板3411上，具体实施时，叶片342的直线段部分可设置有缺口，叶片342可通过该缺口卡接固定在第一固定板3411上。此外，相邻设置的两个叶片342中，其中一个叶片342可设置于第二固定板3412的一侧，另一个叶片342则设置于第二固定板3412的另一侧，从而多个叶片342依次排列即可构成类似螺旋状的结构。在本实施例中，相邻的两个叶片342之间的夹角α可以在75°～90°之间，示例性地，相邻的两个叶片342之间的夹角α具体可以为75°，80°，83°，90°，等等。
另外，在本申请实施例中，叶片342上还可以设置有第一刮片343，第一刮片343可大致为矩形结构，第一刮片343的端部可延伸出叶片342背离转轴341的一侧，也即第一刮片343的端部可超出叶片342的圆弧段设置。第一刮片343可以采用柔性材质，例如可以为聚对苯二甲酸乙二醇酯(polyethylene glycol terephthalate，PET)。在将第一刮片343与叶片342连接时，第一刮片343具体可通过粘贴结合热熔的方式固定在叶片342上。第一刮片343的材质相较于塑胶的叶片342来说相对偏软，当转轴341转动时，第一刮片343的端部可以与粉仓330的内壁接触摩擦，从而可以保证墨粉能够被充分搅拌，避免由于叶片342的端部与粉仓330的内壁挤压或者接触不到内壁而造成墨粉的输送效率过低，另外还可以减小第一搅拌辊340的扭矩，进而降低墨粉盒向硒鼓组件输送墨粉的负载。
请继续参考图5和图6，转轴341上还可以设置有第二刮片344，第二刮片344也可以大致为矩形结构。具体实施时，第二刮片344可以设置于转轴341上与补给口相对应的位置，以在转轴341转动时，第二刮片344可以将粉仓330内补给口处的墨粉传送至粉仓330的外部，从而提高墨粉的输送效率。示例性地，第二刮片344的材质也可以为PET，这样第二刮片344的端部也可以与粉仓330的内壁接触摩擦，从而使得补给口处的墨粉能够被充分搅拌。另外，第二刮片344的数量可以为两个，两个第二刮片344可相对转轴341呈中心对称设置，示例性地，两个第二刮片344可固定在第一固定板3411上，且分别位于第二固定板3412的两侧；或者，两个第二刮片344也可固定在第二固定板3412上，且分别位于第一固定板3411的两侧。
应当理解的是，在另外一些实施例中，叶片342也可以为一体式螺旋结构，此时，叶片342可直接环绕设置在转轴341的外壁，这种设计同样可以实现对墨粉的输送，具体此处不再过多赘述。
需要说明的是，在本实施例中，墨粉盒300还可以包括第一齿轮360，第一齿轮360 可设置于粉仓330的端部与盒体的内壁之间，例如图6中以第一齿轮360设置于粉仓330的第一端332为例进行说明。此时，粉仓330的第一端332可设置有穿过孔，转轴341的端部可通过穿过孔伸出至粉仓330的外部与第一齿轮360固定连接。在将墨粉盒300安装于硒鼓组件上之后，可通过硒鼓组件的驱动电机驱动第一齿轮360转动，进而带动第一搅拌辊340同步转动。
图7为本申请实施例提供的墨粉盒的局部结构示意图。一并参考图2和图7所示，在一些实施例中，手柄320可设置于盒体310的第一侧，也即前壳311背离盖体312的一侧。具体实施时，手柄320可包括第一滑轨321和手柄本体322，第一滑轨321可固定设置在粉仓330背离盖体312的一侧，且第一滑轨321可沿粉仓330的长度方向(x方向)设置，手柄本体322滑动装配在第一滑轨321上。盒体310的第一侧可设置有开孔313，开孔313可沿x方向延伸，手柄本体322可穿过开孔313暴露于盒体310的外侧，以便于用户操作。另外，手柄320还可以包括连接臂323，连接臂323的一端与手柄本体322连接，另一端可穿过粉仓330与盒体310的内壁之间的缝隙，延伸至盒体310的第二侧，也即盖体312所在的一侧。
第一仓门350可设置于盒体310的第二侧。这时，粉仓330的外壁可设置有第二滑轨334，第二滑轨334也可沿x方向设置，第一仓门350可滑动装配在第二滑轨334上。需要说明的是，盒体310的第二侧所开设的窗口3121的尺寸可大于第一仓门350的尺寸，此时，在盒体310的第二侧，第一仓门350具体可滑动设置于窗口3121内。第一仓门350上设置有第一开口351，第一开口351的形状可与补给口331的形状相一致。另外，粉仓330朝向第一仓门350的一侧可设置有第一泡棉335，第一泡棉335可被挤压在第一仓门350与粉仓330的外壁之间，从而可以提高第一仓门350对补给口331的密封效果。应当理解的是，第一泡棉335上对应粉仓330的补给口331的位置设置有与补给口331的形状相匹配的通孔，以避免在第一仓门350将补给口331打开时对补给口331造成遮挡，保证粉仓330内的墨粉能够顺利输送到硒鼓组件。
第一仓门350与连接臂323之间固定连接，具体设置时，连接臂323远离手柄本体322的一端可设置有凹槽3231，第一仓门350可设置有朝向盒体310的第一侧设置的延伸部352，该延伸部352可嵌设于凹槽3231内，从而利用凹槽3231的内壁对延伸部352在x方向进行限位，进而实现第一仓门350与连接臂323的卡接固定。当用户操作手柄本体322沿第一滑轨321滑动时，第一仓门350就可在连接臂323的带动下沿第二滑轨334产生同方向的移动。
需要说明的是，为了提高手柄本体322与第一仓门350之间的连接可靠性以及第一仓门350的运动平稳性，在本申请实施例中，连接臂323的数量具体可以为两个，两个连接臂323相对设置，可分别穿过粉仓330上方和粉仓330下方与盒体310之间的缝隙与第一仓门350连接。需要说明的是，本申请实施例的墨粉盒300所采用“上”“下”等方位用词主要依据墨粉盒300于图3中的展示方位进行阐述，并不形成对墨粉盒300于实际应用场景中的方位的限定。
另外，请参考图7所示，在本实施例中，连接臂323的端部可尽量靠近第二滑轨334设置，也即使连接臂323与第一仓门350的卡接位置尽量靠近第二滑轨334设置，这样可以减小第一仓门350的受力点与第二滑轨334之间的距离，进而可以减小连接臂323所施加给第一仓门350的偏转力矩，使第一仓门350可以顺畅地在第二滑轨334上滑动，提高 第一仓门350的运动平稳性。示例性地，连接臂323与第一仓门350的卡接位置与第二滑轨334之间的距离可不大于2mm。
图8为本申请实施例中的墨粉盒在一种工作状态下的结构示意图，图9为本申请实施例中的墨粉盒在另一种工作状态下的结构示意图。一并参考图7、图8和图9所示，盒体310上可设置有第一卡勾314，第一卡勾314可暴露于盒体310的窗口3121内，例如可以暴露于窗口3121靠近粉仓330的第一端332的一侧。第一仓门350上可设置有卡槽353，当第一仓门350滑动至窗口3121靠近粉仓330的第一端332的一侧时，卡槽353可与第一卡勾314配合卡接，以将第一仓门350锁定在该位置，此时，第一仓门350的第一开口351与粉仓330的补给口错位设置，第一仓门350可将粉仓330的补给口封闭，从而避免粉仓330内的墨粉泄露。当第一卡勾314在外力作用下与卡槽353解除卡接时，第一仓门350可在手柄320的带动下在窗口3121内滑动，当第一仓门350滑动至第一开口351与补给口的位置相对时，粉仓330内的墨粉可依次通过补给口、第一开口351以及窗口3121输送至墨粉盒300的外部。可以理解的是，第一仓门350被第一卡勾314锁定时，手柄320也会被锁定在某一位置，此时用户无法通过滑动手柄320解锁第一仓门350，从而可以防止由于误操作而导致墨粉泄露的问题。
值得一提的是，第一滑轨321远离粉仓330的第一端332的一侧可设置有限位结构，该限位结构可用于在第一仓门350将补给口打开时对手柄本体322进行阻挡，以避免手柄本体322继续滑动而导致第一仓门350再次将补给口遮挡，保证能够顺利向硒鼓组件输送墨粉。当然，在其它一些实施例中，第二滑轨334远离粉仓330的第一端332的一侧也可设置类似的限位结构，以在第一仓门350将补给口打开时对第一仓门350进行阻挡，具体此处不再过多赘述。
在一些实施例中，第一卡勾314的数量可以为两个，两个第一卡勾314可上下排列，也即沿墨粉盒300的高度方向并列设置。相应地，卡槽353的数量也可以为两个，两个卡槽353与两个第一卡勾314可一一对应卡接，从而提高对第一仓门350的锁定可靠性。
图10为本申请实施例中的硒鼓组件的局部分解示意图，图11为本申请实施例中的硒鼓组件在一种工作状态下的结构示意图，图12为本申请实施例中的硒鼓组件在另一种工作状态下的结构示意图。一并参考图10至图12所示，硒鼓组件200包括仓体210和第二仓门220，上述用于容置墨粉盒的容置槽211即设置于该仓体210的一侧，容置槽211的底部设置有进粉口212，进粉口212可将仓体210的内部与容置槽211连通，也即与仓体210的外部连通。在将墨粉盒安装于容置槽211内之后，进粉口212可与粉仓的补给口位置相对。另外，容置槽211的第一端2111可设置有第二齿轮213，第二齿轮213可与硒鼓组件200的驱动电机传动连接，墨粉盒安装到位之后，第二齿轮213可自动与墨粉盒的第一齿轮啮合，从而将驱动电机的驱动力传递给第一齿轮，带动墨粉盒的第一搅拌棍转动。
容置槽211的底部设置有第三滑轨214，第三滑轨214可沿x方向延伸，第二仓门220可滑动装配在第三滑轨214上。第二仓门220上设置有第二开口221，第二开口221的形状可与进粉口212的形状相一致。当第二仓门220位于第三滑轨214靠近容置槽211的第一端2111的一侧时，第二开口221与进粉口212位置相错，此时第二仓门220可将进粉口212封闭。当第二仓门220向远离容置槽211的第一端2111的方向滑动至第二开口221与进粉口212位置相对时，进粉口212被打开，墨粉盒内的墨粉可依次通过第二开口221和进粉口212进入仓体210的内部。
另外，容置槽211的底部可设置有第二卡勾215，示例性地，第二卡勾215可靠近容置槽211的第一端2111设置。第二卡勾215可包括弹性臂2151以及设置于弹性臂2151背向仓体210内部的一侧的卡勾本体2152和凸起部2153，其中，卡勾本体2152位于弹性臂2151远离容置槽211的第一端2111的端部，凸起部2153位于卡勾本体2152靠近容置槽211的第一端2111的一侧。当第二仓门220位于第三滑轨214上靠近容置槽211的第一端2111的一侧时，卡勾本体2152可与第二仓门220的第二开口221卡接，凸起部2153则位于第二开口221的外部，此时第二卡勾215可将第二仓门220锁定在该位置，避免仓体210内部的墨粉泄露。当凸起部2153受到朝向仓体210内部一侧的外力作用时，弹性臂2151超向仓体210内部的一侧弯曲，从而带动卡勾本体2152也朝向仓体210内部的一侧移动，进而可以解除对第二仓门220的锁定，使第二仓门220可以沿第三滑轨214滑动。
在一些实施例中，容置槽211的底部可设置有第二泡棉216，第二泡棉216可被挤压在第二仓门220与容置槽211的底部之间，从而提高第二仓门220对进粉口212的密封效果。另外，第二仓门220背向仓体210内部的一侧还可设置有第三泡棉222，在将墨粉盒安装于容置槽211内之后，第三泡棉222可被挤压在第二仓门220与第一仓门之间，从而减小墨粉在墨粉盒与硒鼓组件200之间泄露的风险。类似地，第二泡棉216上对应进粉口212的位置设置有与进粉口212形状相匹配的通孔，第三泡棉222上对应第二仓门220的第二开口221的位置设置有与第二开口221形状相匹配的通孔，以避免在第二仓门220将进粉口212打开时对进粉口212造成遮挡。
请一并参考图8、图9、图11和图12所示，第二仓门220背向仓体210内部的一侧设置有凸筋223，凸筋223的尺寸可大致等于卡槽353的尺寸，当墨粉盒300安装于容置槽211内之后，凸筋223可插入第一仓门350的卡槽353内，第一卡勾314受到凸筋223的挤压后变形并回缩到盒体310内侧，解除对第一仓门350的锁定。与此同时，盒体310的外壁会与第二卡勾215的凸起部2153抵接，从而对凸起部2153施加朝向仓体210内部的外力，使第二卡勾215解除对第二仓门220的锁定。这时，基于凸筋223与卡槽353的相互配合，第一仓门350与第二仓门220在x方向相互锁定。在墨粉盒300安装到位后，当用户操作手柄带动第一仓门350滑动时，第二仓门220也会同步滑动，这样，在第一仓门350滑动至将补给口打开时，第二仓门220也同步滑动至将进粉口212打开，从而将墨粉盒300与硒鼓组件200内部之间的通路连通，使墨粉盒300内的墨粉能够顺利地输送到硒鼓组件200内部。
图13为进粉口打开时第一仓门在硒鼓组件侧的状态示意图。一并参考图12和图13所示，在本申请实施例中，容置槽211的底部可设置有限位臂217，限位臂217位于第三滑轨214远离容置槽211的第一端2111的一侧，且限位臂217与容置槽211的底部之间可具有一定的间隙。在将墨粉盒300安装进容置槽211内后，用户操作手柄带动第一仓门350和第二仓门220同步滑动，当补给口和进粉口212分别打开时，第一仓门350可滑动至限位臂217与容置槽211的底部之间的间隙内，这时，第一仓门350朝向粉仓330的一侧可与限位臂217抵接，从而在墨粉盒300与容置槽211的插接方向对墨粉盒300进行限位，避免墨粉盒300在激光打印机工作过程中松动或者掉落，保证激光打印机的工作可靠性。
图14为本硒鼓组件与墨粉盒组装之后的结构示意图，图15为图14中所示的组装结构在A-A处的局部截面结构示意图。一并参考图13至图15所示，在本实施例中，沿墨粉盒300的长度方向，盒体310的端部可设置限位轴315，容置槽211的侧壁设置有导向滑 槽2112，在将墨粉盒300安装进容置槽211内时，限位轴315可对应装配在导向滑槽2112内，从而利用限位轴315与导向滑槽2112的配合对墨粉盒300的插接过程进行限位。另外，容置槽211内还可设置有扭簧218，扭簧218的一端与仓体210固定连接，另一端具有弯曲部2181，弯曲2181部可位于导向滑槽2112的上方，且弯曲部2181具体可朝向背离导向滑槽2112的一侧弯曲，这时，弯曲部2181与导向滑槽2112的底部之间可形成一限位空间2113。当限位轴315沿导向滑槽2112向靠近容置槽211底部的方向滑动，在经过弯曲部2181时，弯曲部2181在限位轴315的抵接作用下产生弹性变形，使得限位轴315能够经过弯曲部2181的下方进入到后侧的限位空间2113内，之后弯曲部2181在弹性作用下恢复到初始位置，将限位轴315限定在限位空间2113内。采用这种设计，一方面可以使用户较为容易地辨认墨粉盒300是否安装到位，另一方面弯曲部2181也可以施加给限位轴315一定的抵接力，使墨粉盒300可以更稳定地固定在容置槽211内。
图16为图14中所示的组装结构在B-B处的局部截面结构示意图。参考图16所示，硒鼓组件200还可以包括设置在仓体210内部的第二搅拌棍230、补给棍240、显影棍250、显影刮刀260、感光鼓270以及充电辊280。其中，第二搅拌棍230、补给棍240、显影棍250和感光鼓270沿远离进粉口212的方向依次排布，且补给棍240的周侧表面与显影棍250的周侧表面相接触，显影棍250的周侧表面与感光鼓270的周侧表面相接触。显影刮刀260设置于显影棍250的一侧，例如可设置于显影棍250的上方，显影刮刀260与显影棍250的周侧表面接触设置，这样在显影棍250转动时，显影刮刀260可与显影棍250的周侧表面产生摩擦。充电辊280设置于感光鼓270的一侧，例如可设置于感光鼓270的上方，且充电辊280的周侧表面与感光鼓270的周侧表面相接触。
当补给口331和进粉口212分别打开后，墨粉盒300内的墨粉在第一搅拌棍340的作用下被输送到仓体210内，在设置于进粉口212处的第二搅拌棍230的作用下继续向仓体210的左侧输送，然后位于第二搅拌棍230左侧的补给棍240在转动时就可在其周侧表面裹上墨粉。其中，第二搅拌棍230的结构可与第一搅拌棍340的结构类似，此处不再过多赘述。
显影辊250的表面材料为带电橡胶，补给棍240上的墨粉可在其与显影棍250相向转动时被挤压涂覆在显影棍250的表面，这时墨粉不显极性。当显影棍250载着墨粉转动并与显影刮刀260相切，显影刮刀260的尖端放电，可以使墨粉带上负电荷。墨粉在显影刮刀260和磁场作用下，在显影棍250表面形成相对较薄且分布均匀的墨粉雾。
感光鼓270是光敏器件，具有受光导通的特性。感光鼓270表面的光导涂层在扫描曝光前，可由充电辊280充上均匀的电荷。当激光打印机内部的激光器以点阵形式将激光束扫描到感光鼓270上时，被扫描的点因曝光而导通，电荷由导电基对地迅速释放，而没有被扫描的点仍然维持原有电荷，这样在感光鼓270表面就形成了一辐电位差潜像，也即静电潜像。当带有静电潜像的感光鼓旋转到与载有墨粉的显影棍250接触时，就可以把显影棍250表面带有相反电荷的墨粉吸附到感光鼓270表面，从而形成墨粉图像。
当载有墨粉图像的感光鼓270继续旋转，到达图形转印装置时，打印纸也同时被送到感光鼓270与图形转印装置之间，此时图像转印装置在打印纸背面释放一个强电压，将感光鼓270上的墨粉像吸引到打印纸上，再将载有墨粉图像的打印纸送入高温定影装置加温、加压热熔，墨粉融化后浸入到打印纸中，最后输出打印完成的文本或图像。
需要说明的是，硒鼓组件200还可以包括齿轮组以及驱动电机，具体设置时，齿轮组 可包括与感光鼓270、显影棍250、补给棍240以及第二搅拌棍230一一对应设置的多个齿轮，这些齿轮之间依次啮合，驱动电机可与感光鼓270处的齿轮传动连接，这样，驱动电机输出的驱动力就可依次传递至感光鼓270、显影棍250、补给棍240以及第二搅拌棍230，从而驱动硒鼓组件200整体运转。另外，第二搅拌棍230的右侧还可设置齿轮轴，齿轮轴的一端位于仓体210的内部并通过第三齿轮与第二搅拌棍230处的齿轮啮合，齿轮轴的另一端可由容置槽的端部伸入容置槽内，前述第二齿轮即设置于齿轮轴的该端。这样，驱动电机传递至第二搅拌棍230的驱动力可继续由齿轮轴向右侧传递，最终传递给墨粉盒300的第一齿轮。
通过以上描述可以看出，本申请实施例中的墨粉盒300与硒鼓组件200独立设置且可实现互锁，使激光打印机可实现单独更换墨粉盒300，更换步骤较为简单，并且由于墨粉盒300内不包含感光鼓270及显影棍250等部件，因此更换成本也较小。另外，墨粉盒300与硒鼓组件200沿激光打印机的横向(例如长度或宽度)方向排布，相比于现有技术中墨粉盒300与硒鼓组件200竖直叠置的方式，有助于缩小激光打印机的高度尺寸。在更换墨粉盒300时，只需在激光打印机侧面的安装孔内取出及安装墨粉盒300，无需打开激光打印机上盖，用户操作时不会看到除硒鼓组件200之外的打印机内部零部件，因此有助于提升用户的使用体验。
以上，仅为本申请的具体实施方式，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以权利要求的保护范围为准。
