Description

一种用于喷墨打印机的墨盒
技术领域
本发明涉及打印机装置， 尤其是一种用于喷墨打印机的墨盒。 背景技术
目前， 现有用于喷墨打印机的墨盒一般包括盒体和设在盒体内的储墨腔， 盒体底部设有出墨口， 盒体顶部设有进气孔和注墨口， 出墨口、 进气孔和注 墨口分别与储墨腔连通， 储墨腔注满墨水后利用贴膜密封。 墨盒使用过程中， 会有空气进入储墨腔并形成气泡， 气泡可能会阻碍墨水从出墨口正常流出， 从而影响打印效果； 另一方面， 储墨腔注满墨水时， 出墨口的墨水压力较大， 出墨量较多， 使得打印出的图文过浓， 并且降低了墨盒的使用寿命。
发明内容
针对以上现有喷墨打印机墨盒的不足， 本发明的目的是提供一种出墨更 加均匀、 使用寿命更长， 打印效果更好的用于喷墨打印机的墨盒。
本发明的目的是通过采用以下技术方案来实现的：
一种用于喷墨打印机的墨盒， 包括盒体和设在盒体内的储墨腔， 盒体底 部设有出墨口， 盒体顶部设有进气孔和注墨口， 所述出墨口、 进气孔和注墨 口分别与储墨腔连通， 所述储墨腔内设有滤芯腔， 滤芯腔通过滤芯孔与设在 储墨腔另一侧盒体上的引流槽连通， 引流槽的另一端连通出墨口。
作为本发明的优选技术方案， 所述引流槽横向设在盒体上， 引流槽与出 墨口连通的一端设有气泡腔， 所述气泡腔的宽度大于引流槽的宽度。
作为本发明的优选技术方案， 所述滤芯孔的直径大于引流槽的宽度。 作为本发明的优选技术方案， 所述滤芯腔内设有滤芯。
作为本发明的优选技术方案， 所述储墨腔内设有相互连接的纵向隔板和 横向隔板， 所述纵向隔板或横向隔板上设有凹槽。
作为本发明的优选技术方案， 所述横向隔板设有一折边， 横向隔板及其 折边与储墨腔底边构成减压腔， 所述减压腔与滤芯腔连通。
作为本发明的优选技术方案， 所述储墨腔内设有相互交叉的纵向隔板和 横向隔板， 所述纵向隔板或横向隔板上设有凹槽。
作为本发明的优选技术方案， 所述盒体上设有单向阀， 盒体的进气孔通 过单向阀与储墨腔连通。
本发明的有益效果是： 相对于现有技术， 墨盒使用过程中形成的气泡可 以储存于盒体上的气泡腔内， 避免阻碍墨水从出墨口正常流出； 另一方面， 储墨腔注满墨水时， 纵向隔板、 横向隔板、 减压腔和滤芯孔可以有效降低液 压， 从而使出墨口的墨水压力基本保持一致， 使出墨更加均勾， 延长了墨盒 的使用寿命， 并且打印更均匀、 效果更好。
