Description

一种调色剂盒及调色剂接收组件 技术领域
本申请涉及成像装置技术领域，尤其涉及一种调色剂盒及调色剂接收组件。
背景技术
激光打印机、复印机等电子成像装置在打印物质消耗完之后，需要直接更换调色剂盒(如具有显影辊等部件的处理盒、显影盒或者容纳墨水的墨盒、墨罐等)，这样旧的调色剂盒都将直接报废，无法再次使用，造成了资源浪费。
如图1和图2所示，目前有一种可以针对电子成像装置1(激光打印机)内的处理盒2进行补充碳粉的外置加粉盒9，在电子成像装置1内的处理盒2的碳粉使用完之后，其可以将碳粉直接通过调色剂接收组件10的输入口向安装在电子成像装置1中的处理盒2注入碳粉，增加处理盒2的使用寿命。其具体使用方式是将处理盒2安装至电子成像装置1中，当处理盒2内的碳粉消耗至低碳粉量时，电子成像装置1提示添加碳粉，此时使用者可以通过加粉盒9添加碳粉，碳粉从调色剂接收组件10进入到处理盒2的粉仓21中。
现有的处理盒，在快速填充碳粉时，由于处理盒内部的气压急剧增加，容易导致碳粉从显影辊22与盒体之间的间隙泄露。

实施例一
参考图1‐图2所示，处理盒2(调色剂盒的一种)可拆卸地安装至电子成像装置1中，加粉盒9可通过与处理盒2连接的调色剂接收组件10向处理盒2添加碳粉、墨水等打印物质(也称为调色剂)。
如图1和图2所示，处理盒2包括粉仓21、显影仓23、废粉仓24和调色剂接收组件，其中显影仓23设置有显影辊22，废粉仓24设置有与显影辊22接触的感光鼓25；粉仓21用于容纳调色剂，粉仓21位于废粉仓24上方并与显影仓23连通，以能够向显影仓23提供调色剂。
如图3和图4所示，本实施例提供一种调色剂接收组件A10，调色剂接收组件A10与粉仓21连通，调色剂接收组件A10可以设置于粉仓21沿显影辊22长度方向的一端。调色剂接收组件A10包括静止基座51、旋转座52和盖部53， 其中静止基座51上设置有输入口511、连通口512(参考图10)以及连接输入口511和连通口512的通道513(参考图10)，其中输入口511用于接收碳粉(调色剂的一种)，连通口512连通处理盒的粉仓21，以允许碳粉传输至处理盒的粉仓21，连通口512可以形成在通道513的侧壁，也可以是通道513的底部。
旋转座52设置在静止基座51上，可相对静止基座51旋转。旋转座52还包括用于打开或关闭输入口511的开闭件521，本实施例的开闭件521能够随着旋转座52的旋转而旋转，如图4所示，开闭件521随着旋转座52旋转了预设的角度，开闭件521可以是板状构件。盖部53覆盖在旋转座52的外部，以保护旋转座52等部件。
如图5‐图7所示，本实施例提供了一种容纳碳粉的加粉盒4作为调色剂填充装置的一个示例，本实施例的加粉盒4包括用于容纳碳粉的主体41和用于推送碳粉的推送构件42，主体41的下方设置有输出口611，推送构件42包括插入主体41内部的活塞杆421，活塞杆421能够上下移动，以将碳粉从输出输出口611推到主体41外部。
如图5‐图7所示，加粉盒4的下端设置有输出组件6，输出组件6包括活动件61、遮板62以及存储介质端子63，其中活动件61与主体41连接，能随主体41一起旋转，活动件61设有偏离输出组件6旋转中心线的输出口611和偏离输出组件6旋转中心线的凹口612，输出口611能够连通主体41的内部，输出口611可以是椭圆形、圆形、方形或其他各种几何形状的通孔；凹口612向活动件61的外边缘延伸，凹口612设于活动件61远离活塞杆421的一侧，凹口612可以是弧形的凹槽结构。遮板62位于活动件61的下侧，遮板62安装于主体41下端，遮板62与主体41可以是过盈配合，遮板62能够相对活动件61的旋转保持在静止位置，遮板62设置有啮合结构621，啮合结构621偏离输出组件6的旋转中线，能够在加粉盒4插入调色剂接收组件A10时与静止基座51的输入口511的外缘部分511a啮合，啮合结构621可以是形成于遮板62上的一个弧形的缺口部。
参考图1至图7，新的加粉盒4插入到调色剂接收组件A10中，此时开闭件521处于关闭输入口511的位置，活动件61的凹口612卡合在开闭件521的外缘处，遮板62的啮合结构621与静止基座51的输入口511的外缘部分511a啮合且不与开闭件521干涉，使用者沿顺时针方向(也可以设置为逆时针方向)旋转加粉盒4，活动件61带动开闭件521相对遮板62旋转，由于遮板62的啮合结构621与静止基座51的输入口511的外缘啮合，遮板62保持静止状态，随着活动件61旋转，输出口611与静止基座51的输入口511重叠；此时使用者按压活塞杆421完成碳粉填充，此时加粉盒4中的空气和碳粉会一起进入处理盒的粉仓21中。
如图8和图9所示，本实施例的处理盒还设置有通气孔71以及设置在通气孔71上的过滤装置72，通气孔71以及过滤装置72优选设置在调色剂接收组件A10和/或连通口512附近；在本实施例中，通气孔71以及过滤装置72设置在调色剂接收组件A10上，通气孔71可以开设在调色剂接收组件A10的侧壁上。
在一些实施方式中，通气孔71设置在粉仓21上，沿着显影辊22的长度方向，通气孔71设置在粉仓21靠近调色剂接收组件A10的一端，使得通气孔71能够靠近连通口512，将通气孔71开设在连通口512附近能更快地将从加粉盒4压入的空气排出。
在一些实施方式中，调色剂接收组件A10和粉仓21上均设置通气孔71，且通气孔71上均设置过滤装置72。
具体的，通气孔71与粉仓21和连通口512连通，可以包括多个小孔，小孔的数量可以根据需要进行设置；过滤装置72的作用在于将调色剂(如碳粉)阻挡在处理盒内部，同时允许空气从过滤装置72通过，过滤装置B72可以是海绵或毛毡。
过滤装置72的数量可以根据需要进行设置，例如在通气孔71的内侧设置一个过滤装置72，可选择的，可以在通气孔71的外侧设置一个过滤装置72，还可以在通气孔71的内侧和外侧分别设置一个过滤装置。
通气孔71以及过滤装置72优选设置在调色剂接收组件A10和/或连通口的附近，其能够更好更快地将从加粉盒4压入的空气排出，避免处理盒内部压力过大，造成碳粉从显影辊22与盒体或感光鼓25之间的间隙泄露。
优选的，还可以设置一紧固件，该紧固件压在过滤装置72的外侧，进一步加固过滤装置72，避免过滤装置脱落。优选的，紧固件压迫在过滤装置的外缘。
作为一种变形例，如图10所示，在通气孔71和连通口512附近设置一送粉构件73，以将通气孔71和连通口512附近的碳粉传送至粉仓21内，避免堵塞。
在本实施例中，送粉构件73可旋转地支撑在处理盒的盒体上并位于粉仓21内，其旋转轴线与显影辊22的旋转轴线平行。具体的，送粉构件73包括螺杆部731和叶片部732，螺杆部731的一端延伸至通气孔71的附近，优选地，螺杆部731位于连通孔512的下方侧，螺杆部731旋转时能够将碳粉沿轴线方向传输，从而将通气孔71和连通口512附近的碳粉传输至粉仓21内。叶片部732设置有多片叶片，也可以设置为一片叶片，叶片部732位于粉仓21内，叶片部732可以与螺杆部731相连接，与螺杆部731同步旋转，叶片部732旋转时能够将粉仓21内的碳粉往显影仓23的方向传输。
当加粉盒4往调色剂接收组件A10填充碳粉时，堆积在通气孔71和/或连通孔512附近的碳粉可经螺杆部731沿着旋转轴线方向传输至叶片部732，再由 叶片部732往显影仓23方向推送，避免了碳粉堵塞通气孔71和连通口512。
在一些实施例中，送粉构件73可以仅设置螺杆部731。
在一些实施例中，调色剂接收组件A10不设置旋转座52，也即无需旋转动作直接通过插入加粉盒4进行加粉；调色剂接收组件A10还可以有多种形式结构，此处不再赘述。
实施例二
本实施例提供另一种调色剂接收组件以及处理盒，本实施例的调色剂接收组件以及处理盒的结构与实施例一基本相同，其相同之处不再赘述，与实施例一相比，本实施例的调色剂接收组件还包括单向阀结构A6。
该单向阀结构A6设置在通道513中，单向阀结构A6允许碳粉从输入口511向连通口512方向流动，阻挡碳粉从连通口512向输入口511方向流动；也即，当碳粉从输入口511向连通口512流动时，单向阀结构A6打开，当碳粉从连通口512向输入口511方向流动时，单向阀结构A6能够闭合。优选的，单向阀结构A6设置在靠近输入口511的位置，其有利于碳粉更好地通过单向阀结构A6。
图11和图12示出了其中一种单向阀结构A6，如图所示，单向阀结构A6包括阀座A61和与阀座A61配合的阀芯。
阀座A61，可为环体结构，其外环面密封设置于通道513，在本实施例中输入口511形成与阀座A61的中部(环体结构的中心孔)；可选择的，输入口511与阀座A61可以分开设置，例如阀座A61可以设置在输入口511和连通口512之间，阀座可以设置多个流通口，阀座和设置在在阀座上的流通口的结构、数目和位置关系可根据实际情况进行变动，在此不做具体限定。
如图11和图12所示，本实施例的阀芯为具有弹性的阀片A62，设于阀座A61的朝向连通口512的一侧，阀片A62的朝向阀座A61的一侧形成有密封面A621；如图11所示，当阀片A62处于第一姿态时，密封面A621于阀座A61上的投影覆盖过输入口511(或流通口)，即密封面A621的形状和尺寸大于输入口511(或流通口)，能够完全遮蔽输入口511(或流通口)。密封面A621紧贴阀座A61，具体是紧贴在阀座A61的下端面(朝向连通口512的端面)，以封闭输入口511(或流通口)；如图12所示，当阀片A62处于第二姿态时，密封面A621与阀座A61之间形成通过间隙A63，碳粉经由输入口511(或流通口)和通过间隙A63后流向粉仓21。
阀片A62可采用橡胶之类的弹性材料，其一端(连接端)固定于阀座A61上，另一端(自由端)延伸过输入口511，如图11和图12所示，在阀片A62处于第一姿态时，也就是自然状态下，阀片A62的密封面A621与阀座A61的下端面自然贴合，密封输入口511(或流通口)。而当碳粉从外部进入时，阀片A62 可在外力(例如气压压力、作用部件的抵压力)的作用下弹性变形，阀片A62的自由端朝向连通口512的方向弯折，阀片A62处于第二姿态，阀片A62的自由端与阀座A61之间形成通过间隙A63，碳粉经由输入口511(或流通口)依次经过通道513、连通口512，最终进入粉仓21内。而当碳粉由于自身重力或由于粉仓21内部气压压力过大从连通口512向输入口511方向流动时，阀片A62在自身弹性恢复力作用下，阀片A62的自由端朝输入口511方向运动，将阀片A62的密封面A621推向与阀座A61的下端面贴合，密封输入口511(或流通口)，碳粉无法溢出。
可选择的，阀片A62还可以设置为非弹性结构，例如可相对于阀座A61枢转的板件，其和复位弹簧配合，复位弹簧可以设置在通道513内，在自然状态下，通过复位弹簧的弹力，顶住阀片A62朝向连通口512的一面，使阀片A62与阀座A61的下端面贴合，将输入口511(或流通口)封闭，而在补充添加碳粉时，阀片A62可在外力克服复位弹簧的阻力，将阀片A62顶开，碳粉顺利进入通道513；加粉结束以后，阀片A62在复位弹簧的作用下回到自然状态。
此种结构设计，单向阀结构A6能够阻止碳粉从单向阀结构A6靠近连通口512的一侧移动到单向阀结构A6远离连通口512的一侧，即能够阻挡碳粉从阀片A62朝向连通口512的一侧移动到阀片A62朝向输入口511的一侧，使得在处理盒运输过程中碳粉不会从输入口511泄露。
参考图1至图7、图11和图12，新的加粉盒4插入到调色剂接收组件A10中，此时开闭件521处于关闭输入口511的位置，活动件61的凹口612卡合在开闭件521的外缘处，遮板62的啮合结构621与静止基座51的输入口511的外缘部分511a啮合且不与开闭件521干涉，使用者沿顺时针方向旋转(也可以设置为逆时针方向旋转)加粉盒4，活动件61带动开闭件521相对遮板62旋转，由于遮板62的啮合结构621与静止基座51的输入口511的外缘啮合，遮板62保持静止状态，随着活动件61旋转，输出口611与静止基座51的输入口511重叠；此时使用者按压活塞杆421完成碳粉填充，由于在活塞杆421移动过程中，加粉盒4通过输出口611向阀片A62施加较大的空气压力，此时阀片A62从第一姿态变换至第二姿态，碳粉能够顺利补充至粉仓21内；当加粉完成时，由于加粉盒4向阀片A62施加的空气压力不足以使阀片A62形变时，阀片A62在自身的弹性恢复力作用下返回到第一姿态。
在这种状态下，使用者拔出加粉盒4时，由于加粉盒4处于第一姿态，输入口511(或流通口)处于被关闭的状态，因此即使加粉后粉仓21内部空气压力大于外界的情况下，碳粉也不会从输入口511溢出到外界。
在一些实施例中，调色剂接收组件不设置旋转座52，也即无需旋转动作直接通过插入加粉盒4进行加粉。
在一些实施例中，调色剂接收组件可以不设置开闭件，其结构简单，制造成本低。
实施例三
本实施例提供又一种结构的调色剂接收组件及处理盒，本实施例的调色剂接收组件以及处理盒的结构与实施例一和实施例二基本相同，其相同之处不再赘述，与实施例二相比，本实施例的调色剂接收组件A10的单向阀结构不同。
如图13所示，本实施例提供另一种结构的单向阀结构B6，单向阀结构B6包括：
阀座B61，可为具有凹入部B612的环体结构，其外环面密封设置于通道513，在本实施例中输入口511形成于阀座B61的中部(环体结构的中心孔)；可选择的，输入口511与阀座B61可以分开设置，阀座B61可以设置多个流通口，阀座B61和流通口的结构、数目和位置关系可根据实际情况进行变动，在此不做具体限定。凹入部B612设于阀座B61朝向连通口的一侧。
与阀座B61配合的阀芯，本实施例的阀芯为球体B62，其能够部分嵌入凹入部B612中，并能够关闭输入口511(或流通口)，球体B62能够在第一位置和第二位置之间移动，在第一位置时，球体B62关闭输入口511(或流通口)，在第二位置时，球体B62打开输入口511(或流通口)。
单向阀结构B6还包括弹性部件B63，该弹性部件B63用于使球体B62位于第一位置，具体的在本实施例中弹性部件B63为压缩弹簧，当然也可以是弹性海绵、弹性臂等。弹性部件B63一端设置在弹性安装部B611，弹性安装部B611可以是设置于通道513底部的槽，另一端与球体B62连接，以迫使球体B62位于第一位置。
当推压插入到调色剂接收组件的加粉盒4的活塞杆421时，由于输入口511处的空气压力较大，球体B62克服弹性部件B63的弹性力从第一位置移动至第二位置，输入口511(或流通口)打开，碳粉能够顺利进入。当活塞杆421移动至底部，也即加粉完成时，由于输入口511处的空气压力减小，球体B62在弹性部件B63的弹性恢复力作用下恢复至第一位置，关闭输入口511(或流通口)，阻挡粉仓21碳粉溢出。
在一些实施例中，球体B62还可以替换成其他形状结构，例如椭圆、半球体、正方体等，只要在第一位置能够关闭输入口511或流通口即可。
以上所述的仅是本申请的一些实施方式。对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。
