Description

墨盒 Cartridge

技术领域 FIELD

本发明涉及喷墨打印机用的墨盒,特别是墨腔与打印头之间可分离的墨盒。 The present invention relates to an ink jet printer cartridge, in particular between separable ink chamber of the printhead cartridge.

背景技术 Background technique

现有一种打印机使用的墨盒有如CN1107103A所公开的结构形式,参见图21和图22,图21是其外型图,图22是图21的结构剖视图。 A printer cartridge prior to use of the structure like CN1107103A disclosed, see FIG. 21 and FIG. 22, FIG. 21 is the exterior view of FIG 21 FIG 22 is a structural cross-sectional view. 为说明问题,图中给出的是一个单色墨盒(多色墨盒的结构及工作原理基本类似),它有一个墨腔内置有充满墨的海棉体49的盒体50,盒体50的底面有一个供墨口51,供墨口51内有用于导墨的导墨件52。 For illustration, the figure shows a monochrome cartridge (structure and working principle is substantially similar to multi-color ink container), which has a built-in ink chamber filled with ink sponge body case 49, 50, cassette 50 a bottom surface of the ink supply port 51, ink supply guide member 52 for guiding the ink within the ink outlet 51. 其盒盖46的结构比较复杂,下层盖47的下表面设有向下挤压海棉49的筋条48,还有一个沟通墨腔和迷宫式气道的入口(不在本图中),上层盖44与下层盖47焊接,形成曲回的迷宫式气道45,在上层盖44上有一个迷宫式气道的出口43,从而一方面保证供墨过程中墨腔内的负压平衡,另一方面当墨盒倒置时墨不会从气道中迅速流出造成污染。 The structure of the cover 46 is more complex, the lower surface of the lower cover 47 is provided with a rib 49 presses down the sponge 48, as well as an inlet (not in the figure) and an ink chamber communicating labyrinth airways, the upper cover 44 and the lower cover 47 welded meander labyrinth airway 45 is formed with a labyrinth airway outlet 43 on the upper cover 44, so that on the one hand to ensure the balance of the negative pressure of the ink chamber during the ink supply, and the other on the one hand when the ink does not flow rapidly from the airway when the ink cartridge upside down pollution.

这种墨盒的不足之处有二,其一是墨腔被海棉占据了较大的体积,因而含墨量受到限制,对用户来说,使用成本高,同时,由于海棉的存在,残墨量较大,给环境造成污染;其二是盒盖的结构复杂,造成墨盒的工艺要求高,成本也高。 Disadvantage of this cartridge are two, one is an ink chamber is sponge occupy a larger volume, and thus the amount of ink containing limited to the user, high cost, at the same time, due to the presence of the sponge, residual large amount of ink, causing pollution to the environment; second cover structure is complicated, resulting in high process requirements of the ink cartridge, the cost is high.

发明内容 SUMMARY

本发明的目的是针对这款打印机的墨盒设计一种新结构,取消墨腔内的海棉,使墨盒的容墨空间相对增大,从而降低墨盒的使用成本。 Object of the present invention is directed to a printer of this cartridge design a new structure, to cancel sponge ink chamber, so that the ink containing space of the ink is relatively increased, thereby reducing the cost of the ink cartridge.

本发明的另一目的是简化盒盖的结构,降低装配工艺要求。 Another object of the present invention is to simplify the structure of the lid, to reduce the assembly process requirements.

本发明的再一个目的是在设计结构时,充分考虑减少残墨,保护环境。 A further object of the present invention is in the design of the structure, sufficiently consider reducing the residual ink, to protect the environment.

为实现上述目的,本发明所提供的墨盒包括内有墨腔的盒体及位于墨腔顶的盒盖,盒盖上有连通墨腔与外界的气孔,盒体底面有内置导墨件的供墨口,盒盖下表面设计成一个包围气孔的上凹腔,气孔在墨腔内的孔口位于该凹腔的下部,并在气孔内置有导气阻液塞,用完的墨盒倒置时,墨腔内少量的残墨将位于凹腔内,此时气孔在墨腔内的孔口高于残墨液面,同时,气孔内还有导气阻液塞,因此,在该部结构简化了的同时,同样起到了防残墨流出造成污染的目的。 To achieve the above object, the present invention provides an ink cartridge including an ink chamber within the cassette body and the lid located at the top of the ink chamber, an ink chamber communicating with the outside of the hole on the cover, the cassette body bottom surface by the built ink-inducing element the ink supply port, the lower surface of the cover designed as a cavity surrounded by the hole, the hole in the lower cavity in the aperture of the ink chamber, and the air resistance hole guide built liquid slug, depleted container when inverted, a small amount of residual ink of the ink chamber will be located within the cavity, then opening pores in the ink chamber is higher than the level of residual ink, while the guide hole as well as gas barrier liquid slug, thus simplifying the structure at the same time, also played object of preventing the ink outlet polluting residues. 盒盖上有一排斜面定位筋,用于装入打印机时在盒仓内挤紧定位,可以防止墨盒相对盒仓在水平面内及垂直方向发生晃动,提高供墨质量。 A row of ribs on the cover bevel position for squeezing into the printer when the cartridge is positioned in the cartridge, shake the toner cartridge can be prevented from occurring relative to the cassette holder in the horizontal and vertical directions, to improve the quality of the ink supply. 可见,盒盖结构相对简化,使该部件的制造及墨盒的装配工艺得以简化,降低了产品的次品率。 Be seen, the lid structure is relatively simplified, so that manufacturing and assembly process of the cartridge member can be simplified, reducing the rate of defective products. 盒体侧面设有单向阀,单向阀入口与墨腔底部连通,出口通向供墨口。 Cassette side provided with a check valve, the check valve inlet in communication with the bottom of the ink chamber, an outlet leading to the ink supply port. 供墨口在导墨件的外侧还置有一个密封圈,供墨口有着由圆向椭圆过渡的外张喇叭孔,便于墨盒装入护罩及打印机盒仓时的顺利就位。 The ink supply port outside the ink-inducing element is also equipped with a seal, the ink supply port has a flared transition to the elliptical horn aperture by a circle, to facilitate the smooth shield in place when the cartridge into the printer and the cassette holder. 由于单向阀的入口与墨腔的底部连通,在非长期搁置断断续续工作的情况下,基本可使腔内的墨用尽,残墨量明显低于海棉墨盒。 Since the bottom of the case communicates with the ink chamber of the inlet check valve, resting in a non-permanent off work, the ink chamber can substantially exhausted, significantly lower than the amount of residual ink cartridge sponge.

采用的单向阀为一组件,由底套、压盖及周边挤压固定在两者之间的皮碗构成,底套中心有一阀出口,在出口所在的端面上成形有四个凸块及围绕出口的一个凸环,凸环与凸块同高且有四道槽口,从而可与安装穴内壁或封膜一同构成墨道的一部分。 A check valve assembly is used, the pressing by the bottom sleeve, and the gland is fixed to the periphery of the cup configuration therebetween, said bottom end cap has an outlet valve, formed with four projections located at the outlet end face and around the outlet of a convex ring, collar, and the bump has the same height as four slots, whereby mounting hole may constitute a part of the inner wall or the sealing film ink channels together. 压盖中心为一阀面,边缘有阀入口,皮碗中心有阀孔,常闭状态是依靠皮碗自身的弹性使阀孔紧密地压在阀面上,阀的导通状态是阀孔在外力作用下离开阀面,这样,单向阀与气孔、供墨口之间的配合可使墨腔内保持压力平衡,从而取代了海棉,虽然,单向阀占有墨腔一定空间,但相对海棉体来说,所占据的空间就小得多了,提高了容墨量。 A valve gland face center, edge valve inlet, a valve cup central aperture, a normally closed cup relying own elasticity tightly press the valve hole in the valve face, the conduction state of the valve is a valve hole valve away from the lower surface of the external force, so that the check valve with the hole, the engagement between the ink supply port allows ink to maintain the pressure balance chamber, thereby replacing the sponge, although the one-way valve occupies a certain space of the ink chamber, but the relative sponge body, the space occupied by a much smaller, the amount of ink to improve the capacity.

本发明的结构可用于单色墨盒,也可用于多色墨盒,即盒体内有三个或三个以上相互独立的墨腔时也同样适用,只要在每个墨腔均设置一个位于盒盖上且相互独立的气孔、上凹腔及导气阻液塞,每个墨腔均设置各自相互独立的供墨口、单向阀及三者之间的连通通道。 Structure of the present invention may be used in monochrome cartridge, also be used for multi-color ink cartridge, i.e., the cartridge body has also applicable when three or more mutually independent ink chambers, each ink chamber is provided as long as each is located on a cover and independent pores, the fluid cavity and the gas barrier plug guide, each passage communicating the ink chamber are disposed between the respective independent ink supply port, and the three-way valve.

墨腔、单向阀及供墨口之间墨道部分由盒体壁围成,部分由成形于盒体外壁上的凹槽与封膜围成,这样的设计可使基于本发明的墨盒使单向阀出入通道内的毛细作用加强,防止断墨,同时,制造中便于成形,工艺性更加合理。 Between the ink chamber, the check valve and the ink supply port of the ink channel portion surrounded by a body wall, formed in part by the groove and the wall of the sealing film cassette enclosed in vitro, this design allows the present invention so that the ink container the check valve and out the capillary channel enhanced to prevent breaking of the ink, while easy to manufacture the forming process of the more reasonable.

本发明还可包括一个至少与墨盒顶面和底面弹性紧压接触的护罩,护罩的上部有一扳手位,用于墨盒与护罩间的装配或分离,与墨盒顶面的结合部设有与气孔位置对应的孔封,与墨盒底面的结合部设有与供墨口位置对应的口封,这使墨盒从出厂、仓储、运输直到使用前的时间内将墨与空气有效隔绝,保证墨的品质,同时,防止墨的外流。 The present invention further includes a shroud at least a press-contact with the ink elastic top and bottom surfaces, an upper portion of the shroud has a wrench bits for fitting or separation between the ink container and the shroud is provided in connection with the top surface of the ink container portion stomatal aperture closure position corresponding to the bottom surface of the ink cartridge and the engaging portion is provided with a position corresponding to the ink supply port seal opening, which makes the ink container from the factory, warehouse, transportation time until the ink prior to use effectively isolated from the air, to ensure that the ink quality, while preventing the outflow of ink.
