Description

一种碳粉盒 技术领域
本实用新型涉及一种碳粉盒。 背景技术
图像形成装置利用碳粉在打印纸上形成图像。碳粉装在可拆卸于图像形成装置的碳 粉盒中。 当碳粉耗尽的时候, 旧的碳粉盒被新的碳粉盒更换掉。
参见图 1, 图像形成装置 180及碳粉盒 100可拆卸地安装于激光打印机中, 通常, 先安装图像形成装置 180, 然后再安装碳粉盒 100, 且碳粉盒 100也可拆卸地安装在图 像形成装置上。当碳粉盒安装在图像形成装置上后,碳粉盒上的碳粉出口 152与图像形 成装置上的碳粉入口 188对齐配合, 碳粉可从碳粉出口 152流入碳粉入口 188.图 1中 的箭头方向为碳粉盒 100向图像形成装置 180安装的方向 (也是 X的方向)。
参见图 2A和图 2B, 碳粉盒 100的碳粉出口 152会置有开关件 170, 用来打开或关 闭碳粉出口 152。 开关件 170通过旋转轴 402与碳粉盒 100连接, 开关件 170可绕旋转 轴 402旋转, 旋转轴 402上安装有扭簧 (未示出), 扭簧的一个自由端与开关件 170抵 接,另一个自由端与碳粉盒 100的前壁 114抵接,使开关件 170在正常状态下处于关闭 位置 (图 2A)。 在开关件 170的前端上, 还设置有受力部 406, 受力部 406整体向下弯 曲, 受力部 406与图像形成装置 180的碳粉入口 188的棱边 189接触, 以实现开关件 170的打开。 在碳粉盒 100向图像形成装置 180中插入时, 在开关件 170的受力部 406 未与棱边 189接触时, 开关件 170处于关闭位置, 如图 2A所示。 当开关件 170的受力 部 406与棱边 189接触时,开关件 170克服旋转轴 402上的扭簧的扭力向下旋转,开关 件 170处于打开位置, 如图 2B所示, 碳粉出口 152与图像形成装置中的碳粉入口 188 接通, 碳粉从碳粉盒 100中进入到图像形成装置 180中, 参与图像的显影过程。
在开关件 170打开碳粉盒的碳粉出口 152的过程中,如果出现漏粉, 由于开关件旋 转打开时会与碳粉出口成一定的角度,这样碳粉会从碳粉出口 152沿着倾斜的开关件滑 落到图像形成装置中与碳粉出口不相对应的位置而污染图像形成装置中与碳粉出口不 相对应的位置, 另外, 在开关件 170打开碳粉盒的碳粉出口 152的过程中, 在碳粉出口 152与图像形成装置的碳粉入口 188对齐之前就开始打开,碳粉会从碳粉出口 152泄露 到图像形成装置中而污染图像形成装置, 导致打印缺陷, 另一方面会造成碳粉的浪费。 导致打印缺陷。 实用新型内容 本实用新型提供一种碳粉盒,以解决现有碳粉盒开关件旋转打开时会污染图像形成 装置中与碳粉出口不相对应的位置而导致打印缺陷的技术问题。 为了解决以上技术问题, 本实用新型采取的技术方案是:

所述开关件主体上还设置有中间开口。
所述开关件主体在不受外力作用下处于关闭位置时所述中间开口与所述碳粉出口 靠得最近的侧边之间还间隔一定的距离 L。
所述开关件主体的一侧为弹性臂,所述弹性臂的端部外侧面上延伸有突起,所述弹 性臂与主体之间有空隙, 所述开关件主体在与所述弹性臂相对应的另一侧设置有导轨, 所述开关件安装部上设置有第一侧壁和第二侧壁,所述第一侧壁的端部设置有向第二侧 壁方向延伸的延伸部,所述延伸部与开关件安装部之间形成与所述导轨相匹配的的导向 槽, 所述第二侧壁上设置有与所述突起相匹配的滑槽。
所述开关件主体与所述壳体外表面靠近的一面设置有一端开口而另一端封闭容纳 槽,所述壳体外表面与所述容纳槽的侧面开口相对应的位置处设置有阻挡部,所述弹性 元件位于所述容纳槽内,所述弹性元件一端与所述容纳槽的封闭端抵接,另一端与所述 阻挡部抵接。

在采用了上述技术方案后, 由于述开关件在所述安装部平面上滑动,在所述碳粉盒 的安装方向上,所述开关件先于所述碳粉出口与所述碳粉入口保持不动后,所述碳粉出 口再与所述碳粉入口逐渐接通。即通过开关件的平动实现碳粉出口的打开,在打开过程 中漏出的碳粉只会落到图像形成装置中与碳粉出口相对应的位置上,不会出现碳粉从碳 粉出口沿着倾斜的开关件滑落到图像形成装置中与碳粉出口不相对应的位置而污染图 像形成装置中与碳粉出口不相对应的位置,解决了现有碳粉盒开关件旋转打开时会污染 图像形成装置中与碳粉出口不相对应的位置而导致打印缺陷的技术问题,另外, 由于主 体在不受外力作用下处于关闭位置时中间开口与碳粉出口靠得最近的侧边之间还间隔 一定的距离 L 或者主体在不受外力作用下处于关闭位置时主体打开时靠近与碳粉出口 的侧边与碳粉出口靠得最近的侧边之间还间隔一定的距离^ 因此, 在所述碳粉盒装入 图像形成装置中与图像形成装置接触时需要滑动距离 L后碳粉出口才开始被打开,延迟 了碳粉出口被打开的时间, 大大减少了碳粉的泄露。

参见图 7-8, 在通道 242的封闭部分 242b的底部设置有一开关件安装部 270, 开关 件安装部 270为从碳粉盒 200的前壁 214向后壁 216的方向上延伸的一水平平面,开关 件安装部 270与开关件 254的内表面 254b相匹配。在碳粉盒 200的纵向延伸方向上 (" z " 方向), 开关件安装部 270的两端上设置有与开关件安装部 270垂直的开关件安装部第 一侧壁 272和开关件安装部第二侧壁 274,开关件安装部第一侧壁 272和开关件安装部 第二侧壁 274沿碳粉盒 200的前壁 214向后壁 216的方向延伸(在 " x "方向上)。 开关 件安装部第一侧壁 272的端部设置有向开关件安装部第二侧壁 274方向延伸的延伸部 272a, 延伸部 272a与开关件安装部之间形成开关件 270的导向槽 276, 开关件 254的 导轨 258在导向槽 276中滑动。 延伸部 272a扣住开关件 254的导轨 258, 实现开关件 254在开关件安装部 270上的上下 (" y "方向)定位。 靠近碳粉盒 200的前壁 214的一 侧, 开关件安装部第二侧壁 274上设置有滑槽 274a, 开关件 250的弹性臂 256上的突 起 256a卡入到滑槽 274a中,形成开关件 254在开关件安装部 270上的前后(" x "方向) 定位。 滑槽 274a的长度为开关件 250在开关件安装部 270上可运动的距离。 碳粉出口 252是开关件安装部 270向通道 242的封闭部分 242b的内部挖空。 靠近碳粉盒 200的 前壁 214的一侧, 开关件安装部 270上设置有一对阻挡部 278, 阻挡部 278与压簧 251 位于压簧容纳槽 262的端部开口 262a—侧的一端相抵接; 阻挡部 278的截面尺寸小于 压簧 251的容纳槽 262的截面尺寸,保证阻挡部 278可以在压簧 251的容纳槽 262中滑 动。 阻挡部 278位于碳粉出口 252的两侧, 并靠近碳粉盒 200的前壁 214。
结合图 6-9, 具体描述开关件的安装过程。 首先, 使开关件 250的内表面 254b朝 上, 将压簧 251通过容纳槽 262的端部开口 262a插入到容纳槽 262中, 压簧 251的一 端与压簧容纳槽 262封闭端 262b抵接,另一端伸出容纳槽 262的端部开口 262a。然后, 将安装有压簧 251的开关件 250反过来, 使开关件 250的内表面 254b面向开关件安装 部 270, 按压开关件 250的弹性臂 256, 弹性臂 256向开关件 250的内侧弯曲, 使导轨 258可进入到导向槽 276中, 此时, 弹性臂 256上的突起 256a与开关件安装部第二侧 壁 274的侧面抵接。最后,推动开关件 250,导轨 258在导向槽 276中滑动,弹性臂 256 上的突起 256a与开关件安装部第二侧壁 274的侧面上滑动, 直到弹性臂 256上的突起 256a卡入到滑槽 274a中, 此时, 弹性臂 256上的压力释放, 弹性臂 256回弹到自由状 态; 压簧 251伸出容纳槽 262的端部开口 262a的一端与阻挡部 278抵接, 压簧 251在 容纳槽 262中被压缩。 在开关件 250的关闭位置, 在压簧 251 的作用下, 开关件 250 的前端伸出开关件安装部 270, 此时, 开关件 250上的中间开口 260与碳粉盒的出粉口 252相对错开, 碳粉被阻挡, 在碳粉盒的安装方向上 (" X "方向), 开关件 250上的中 间开口 260位于碳粉盒的出粉口 252的下游。 在开关件 250的打开位置, 开关件 250 受力缩回,开关件 250上的中间开口 260与碳粉盒的出粉口 252对接, 出粉口 252被打 开, 碳粉可从出粉口 252和中间开口 260中流出。
参见图 10-11, 具体描述开关件 250在打开碳粉出口 252和关闭碳粉出口 252的过 程。因为本发明中采用的密封件 266是粘贴在开关件 250上,跟随开关件 250—起运动, 为简化描述, 以下省略对密封件 266的状态描述, 开关件 250的运动过程, 就相当于密 封件 266的运动过程。碳粉盒 200在未安装到打印机中之前,开关件 250处于关闭位置, 即开关件 250上的中间开口 260与碳粉盒的出粉口 252相对错开,当沿如图中的箭头方 向向图像形成装置中插入时, 开关件 250上的中间开口 260位于碳粉盒的碳粉口 252 的下游。随着碳粉盒 200的插入,开关件 250的导引面 254al导引开关件 250的外表面 254a与图像形成装置 180的碳粉入口 188 (图 1 ) 的上表面接触。 因为开关件 250的中 间开口 260在碳粉盒 200的安装方向的下游,所以开关件的中间开口 260先与图像形成 装置 180的碳粉入口 188 (图 1 ) 对齐, 与此同时, 开关件 250的受力部 264与图像形 成装置 180的碳粉入口 188的棱边 189 (图 1 ) 抵接 (开关件 250的受力部 264若设置 在开关件的前端,受力部 264与图像形成装置 180的碳粉入口 188的棱边 189的对面位 置的图像形成装置 180的相应部分抵接), 使得开关件 250相对于图像形成装置 180的 碳粉入口 188 (图 1 ) 不动, 此时, 碳粉盒 200的碳粉出口 252仍处于关闭状态, 如图 9所示状态。当进一步将碳粉盒 200向打印机中插入,碳粉盒的出粉口 252向开关件 250 上的中间开口 260及图像形成装置 180的碳粉入口 188 (图 1 ) 靠近, 开关件 254的导 轨 258在导向槽 276中、开关件 250的弹性臂 256上的突起 256a在滑槽 274a中、阻挡 部 278在压簧 251的容纳槽 262中滑动,压簧 251被压缩。当碳粉盒 200安装到极限位 置, 即碳粉盒 200的第二端盖 220上的限位凹槽 221与图像形成装置上的限位突起 187 抵接, 碳粉盒 200相对于图像形成装置 180静止, 碳粉盒的出粉口 252与开关件 250 上的中间开口 260及图像形成装置 180的碳粉入口 188 (图 1 ) 对齐, 开关件 250打开 碳粉盒的碳粉出口 252, 碳粉可从碳粉盒 200供应到图像形成装置 180中。
因为开关件 250上的中间开口 260位于碳粉盒的碳粉出口 252的下游,实现开关件 250上的中间开口 260先与图像形成装置 180的碳粉入口 188对齐,再到碳粉盒的碳粉 出口 252、中间开口 260和图像形成装置 180的碳粉入口 188对齐的分段式打开碳粉盒 的出粉口的结构,可以有效地改善碳粉盒在出粉口打开的过程中碳粉泄露的问题。如果 出现漏粉, 由于开关件包括中间位置设置有中间开口的主体,主体在碳粉出口位置处与 壳体外表面滑动连接,主体与壳体之间设置有压簧。即通过开关件的平动实现碳粉出口 的打开, 在打开过程中漏出的碳粉只会落到图像形成装置中与碳粉出口相对应的位置 上,出现在不会出现碳粉从碳粉出口沿着倾斜的开关件滑落到图像形成装置中与碳粉出 口不相对应的位置而污染图像形成装置中与碳粉出口不相对应的位置,解决了现有碳粉 盒开关件旋转打开时会污染图像形成装置中与碳粉出口不相对应的位置而导致打印缺 陷的技术问题。
参见图 6, 在碳粉盒 200的主体的前壁 214的底面 217上设置有沿前壁 214向后壁 216方向(" X "方向上)延伸的第一支撑部 217a、第二支撑部 217b和第三支撑部 217c。 第一支撑部 217a、第二支撑部 217b位于前壁 214的底面 217的两侧上,并靠近主体 208 包括第一侧壁 210和第二侧壁 212; 第三支撑部 217c位于前壁 214的底面 217的中间 位置。在碳粉盒 200向打印机中安装的方向上(" X "方向), 第三支撑部 217c位于第一 支撑部 217a、 第二支撑部 217b的下游, 形成三角结构, 使碳粉盒 200在图像形成装置 中 "站立" 的更稳。
当然, 上述主体 254上也可以不设置中间开口 260, 参见图 14-15, 直接用主体 254 在碳粉出口 252上滑动实现开关, 在没有外力的作用下, 主体 254的关闭用侧边 254c 超过碳粉出口关闭碳粉出口, 当主体 254在外力作用下滑动到关闭用侧边 254c到碳粉 出口 252位置时,碳粉出口开始被打开,主体 254在不受外力作用下处于关闭位置时主 体打开时主体的关闭用侧边 254c与碳粉出口 252靠得最近的侧边之间还间隔一定的距 离 L以使碳粉盒装入图像形成装置中与图像形成装置接触时需要滑动距离 L后碳粉出口 252才开始被打开, 延迟了碳粉出口 252被打开的时间, 大大减少了碳粉的泄露。
本实施例中的压簧还可以换成拉簧,如图 16所示,一对拉簧 351设置于开关件 250 的两侧, 拉簧 351的一端与开关件 250连接, 另一端与碳粉盒的壳体连接。 实施例二
图 17为实施例二所采用的开关件及对应的碳粉盒上开关件安装部的结构结构示意 图, 除特殊说明外, 碳粉盒其余部分的结构均和实施例一中的碳粉盒的结构相同。
开关件 450包括开关件主体 455.开关件主体 455与开关件安装部 470通过连接件 460连接, 开关件主体 455可在安装部 470平面上绕着连接件 460自由旋转。 扭簧 480 安装在连接件 460上,一端与开关件主体 455上的阻挡部 451抵接,另一端与碳粉盒的 壳体抵接。 开关件主体 455上设置有导引槽 452, 开关件安装部 470上设置有与开关件 上的导引槽 452匹配的导引柱 472,引槽 452与导引柱 472位于扭簧 480向开关件主体 455施加弹性力的方向上。 开关件主体 455上还设置有受力部 454和中间开口 453. 在开关件 450处于关闭碳粉出口 471的位置, 扭簧 480通过阻挡部 451 向开关件 450施加使中间开口 453远离碳粉出口 471的力,使中间开口 453与碳粉出口 471保持 错开, 实现开关件 450 对碳粉出口的遮挡, 此时碳粉被封闭在碳粉盒中。 导引柱 472 与引槽 452的封闭端抵接,对开关件 450起到限位作用。当碳粉盒向激光打印机中安装 过程中, 开关件 450上的受力部 454与图像形成装置上的棱边 189抵接, 使开关件 450 先相对于碳粉入口 188保持不动,开关件 450上的中间开口 453先与图像形成装置 180 上的碳粉入口 188对齐; 当进一步插碳粉盒,使碳粉出口 471向中间开口 453及碳粉入 口 188滑动, 实现三口 (碳粉出口 471、 中间开口 453和碳粉入口 188 ) 对齐, 此时碳 粉可通过碳粉出口 471、 中间开口 453流入碳粉入口 188中。
本实施例的开关件也可以取消所述中间开口, 相应地减小开关件主体的面积。 当 开关件关闭碳粉出口时,开关件的两侧边分别位置碳粉出口的两侧; 当碳粉出口处于打 开位置时, 开关件的两侧边均处于碳粉出口的同一侧。
本实施例中的扭簧同样也可以换成拉簧, 即拉簧的一端与开关件连接, 另一端与碳 粉盒主体连接。
本实用新型中, 假设开关件完全遮挡碳粉出口时的遮挡量为 " 1 ", 没有遮挡碳粉出 口时的遮挡量为 " 0 "; 碳粉出口与碳粉入口完全对齐时的接通量为" 1 ", 没有对齐时的 接通量为" 0 "。碳粉盒向图像形成装置安装的过程中, 开关件对碳粉出口的遮挡量和碳 粉出口与碳粉入口的接通量的变化如下:
第一阶段, 在开关件未与图像形成装置接触前, 开关件完全遮挡住碳粉出口, 此时 开关件对碳粉出口的遮挡量为 " 1 ", 碳粉出口与碳粉入口的接通量为 "0 "。
第二阶段, 开关件与图像形成装置接触、 但碳粉盒未完全安装到位前, 开关件对碳 粉出口的遮挡量从 " 1 " 向 "0 "变化, 碳粉出口与碳粉入口的接通量从 "0 " 向 " 1 "变 化。
第三阶段, 碳粉盒安装到位, 开关件对碳粉出口的遮挡量变为 " 0 ", 碳粉出口与碳 粉入口的接通量变为 " 1 "。
在碳粉盒从图像形成装置上拆卸过程中,开关件对碳粉出口的遮挡量和碳粉出口与 碳粉入口的接通量的变化与上述步骤相反, 不再赘述。
在所述碳粉出口向所述碳粉入口接近过程中,开关件先于碳粉出口与碳粉入口保持 静止,然后碳粉出口再相对于开关件滑动或转动到碳粉入口接通,大大减少了碳粉盒出 粉口的开关件打开时碳粉泄露的技术问题。
