Description

一种负压式墨盒
技术领域
本实用新型涉及到喷墨打印机所用的墨盒技术领域。
背景技术
传统的墨盒参照图１和图２中所示，一般将进气孔3a和出墨口4a分别设在第一墨水仓1a（又称供墨腔）的仓顶部和仓底部，第一墨水仓1a与第二墨水仓2a之间的隔板5a底部穿孔51a相连。传统的这种墨盒在装机时，先拔掉底盖，撕掉黄色标签，打印开始后，空气从第一墨水仓1a的仓顶部进入，先打印第一墨水仓1a的部分墨水，令海绵6a吸墨不饱满，从而再开始吸其第二墨水仓2a的墨水，这时第一墨水仓1a与第二墨水仓2a间需要空气同墨水交换，空气就从第一墨水仓1a同第二墨水仓2a相连的隔板底部穿孔51a进入，直到把第二墨水仓2a的墨水打完为止。传统的这种墨盒在打印过程中，第一墨水仓1a内的墨水首先减少，在当第一墨水仓1a的墨水减少后，从进气孔3a中向第一墨水仓1a的顶部空间中会及时地补充空气，在第一墨水仓1a中几乎不会产生负压，在待机过程中，就容易出现滴墨现象，从而浪费墨水，污染打印机；再者，在第一墨水仓1a与第二墨水仓2a空气同墨水交换过程中，容易出现交换不及时，从而导致出墨口断墨现象，影响打印质量。(拔掉底盖装机时,海绵在吸墨饱满时会从出墨口漏墨出来)
发明内容
综上所述，本实用新型的目的是为了解决现有墨盒的第一墨水仓缺乏负压，待机滴墨现象，以及第二墨水仓墨水排出不流畅，容易出现断墨的技术缺陷，而提出的一种负压式墨盒。
为解决本实用新型所提出的技术问题，采用的技术方案为：一种负压式墨盒，包括有第一墨水仓和第二墨水仓，在第一墨水仓的底部设有出墨口，其特征是：所述的第二墨水仓的顶部设有进气孔，在第一墨水仓与第二墨水仓之间设有输墨通道，所述输墨通道的进墨端设于第二墨水仓的仓底部，出墨端设于第一墨水仓的仓顶部。
作为对本实用新型作进一步改进的技术方案包括有：
所述的墨盒为内置墨盒。
当为内置墨盒时，所述的第一墨水仓内可能设有纤维棉(也可以没有纤维棉)。
当为内置墨盒时，所述的出墨口中可能设有木棉芯(也可以没有木棉芯)。
当为内置墨盒时，所述的第二墨水仓的仓顶部还设有填充孔，在填充孔中设有密封胶塞。
所述的墨盒为外置墨盒。
当为外置墨盒时，所述的第一墨水仓和第二墨水仓均各设有一个填充孔，在填充孔中设有密封胶塞。
当为外置墨盒时，所述的进气孔上设有进入孔胶塞。
所述的输墨通道为设有第一墨水仓和第二墨水仓侧壁上的凹槽及PP膜构成。
本实用新型的有益效果为：本实用新型将进气孔设在第二墨水仓的顶部，由于第一墨水仓顶部除输墨通道的出墨端之外，为一个完全密封的结构，第一墨水仓内的墨水排出后，无法及时补充空气，在大气压强的作用下，第二墨水仓内的墨水从其底部经输墨通道输送到第一墨水仓顶部，从而补充到第一墨水仓中，当第二墨水仓内的墨水完全打完之后，从进气孔进入的空气才会经输墨通道到达第一墨水仓的顶部，本实用新型打印过程中首先减少的是第二墨水仓内的墨水，第二墨水仓内的墨水减少后，第二墨水仓的墨水液面同第一墨水仓的进墨口形成一个高度差，在第一墨水仓中形成负压，第二墨水仓的墨水液面越低，负压越大，在第二墨水仓内的墨水完全排出后，第一墨水仓的墨水才开始减少，保证了墨水能够稳定的供出，解决了待机滴墨的问题。
