技术领域 FIELD

本实用新型涉及喷墨记录设备例如喷墨打印机使用的墨盒之类的供墨装置,特别是通过将带有墨液通孔的供墨针插入墨盒出墨口内,供墨针刺穿在出墨口端沿或内腔设置的密封片或密封膜,使墨液从出墨口流入供墨针中的墨液通孔的方式实现供墨的墨盒。 The present invention relates to an ink jet recording apparatus such as ink jet printer apparatus using the ink cartridge or the like, especially the ink container through the ink supply needle is inserted into the through-holes with an ink within the ink supply port, the ink supply needle pierces the ink a sealing film or sealing sheet or lumen disposed along the inlet end, so that the ink flows from the ink outlet of the ink supply needle of the ink cartridge through hole manner of supplying ink.

背景技术 Background technique

与喷墨打印机配套使用的墨盒,其主要结构包括用于储藏墨水的储墨腔、与外部环境保持气压平衡的气孔、向打印机的打印头供墨的出墨口。 Supporting the cartridges of the inkjet printer, and its main structure includes an ink reservoir for storing ink, the pressure balance hole to maintain the external environment, an ink outlet supplying ink to the print head of the printer. 在打印过程中,为了保持正常的墨液供应以及墨水的密封储存要求,须使墨盒内的墨水处于适当的负压状态,为实现此种状态通常采用两种方式的技术措施,一则于储墨腔中置入多孔类物质,例如海绵体,由毛细效应保持墨水密封;二则利用墨盒的自身的机械结构,辅之以适当的密封件或单向阀。 During the printing process, in order to maintain a normal ink supply, and sealing the ink storage requirements, the ink in the ink cartridge must be in a proper negative pressure state, this state is implemented using a technique measure in two ways, one in the reservoir an ink chamber into porous substances, such as sponge, the ink is held by the capillary effect sealing; two cartridges using the mechanical structure itself, accompanied by a suitable seal or check valve.

在喷墨打印机运行过程中,与其配套的墨盒,尤其是单纯利用墨盒自身机械结构而不使用海绵类多孔类物的墨盒,其常见的油墨供给方式之一,就是通过将带有墨液通孔的供墨针插入墨盒出墨口内,供墨针刺穿在出墨口端沿或内腔设置的密封片或密封膜,使墨液从出墨口流入供墨针中的墨液通孔的方式实现的。 During the operation of the ink jet printer, the ink cartridge instead of supporting, in particular, the use of a simple mechanical structure without using the cartridge itself cartridge-based porous sponge material, one of the common ink supplying way is through the through-holes with ink the ink supply needle is inserted into the ink supply port showing the ink cartridge, the ink supply needle pierces the sealing film or sealing sheet at the liquid exit end disposed in the lumen or the ink flows from the ink outlet of the ink supply needle of the ink through hole the way to achieve. 通常供墨针采用硬度或强度非常大的金属材料制备,墨盒则采用硬度或强度较大的塑料制备。 Ink supply needle is typically prepared hardness or strength metallic materials using very large, greater hardness or strength cartridge prepared plastic is used. 因此,供墨针和墨盒两者均具有较大的刚性,而塑性较差。 Thus, both the ink supply needle and the ink cartridge having a large rigidity, and poor ductility. 这种状态下,要在供墨针和墨盒之间实现墨液的传输,同时还能防止墨液泄漏,还必须在供墨针和墨盒出墨口之间配备必要的密封手段。 In this state, to be achieved between the ink supply needle and ink cartridge transport, while preventing leakage of the ink, must also be equipped with the necessary means to seal between the ink supply needle in the ink supply port and the ink cartridge. 常见的密封手段通常是在供墨口内设置密封圈。 Common seal means is generally provided in the ink supply port seal. 早期的打印机墨盒常使用其中部带有通孔的密封圈。 Early printer cartridges are often used wherein the seal ring portion with a through-hole. 这种密封圈可箍紧供墨针针杆外表面,在针杆与墨盒出墨口之间提供墨液密封功能,使墨盒内的墨液只能从供墨针中的墨液通孔流出。 The sealing ring may be an outer surface of said rod for tightening the ink needle, a needle bar provided between the ink cartridge and the ink inlet sealing function, so that the ink in the ink cartridge only ink flows out from the through-hole of the ink supply needle . 这种墨盒结构方式,由于密封圈本身带有通孔,致使在安装墨盒过程中,除去出墨口密封膜时会产生少量的墨液泄露,而在拆卸墨盒时,墨盒中的残墨也会自密封圈通孔流出,容易形成工作环境污染,玷污纸张等记录介质。 This container structure, since the seal ring itself with through holes, resulting in the installation process cartridge, an ink outlet when the sealing film is removed a small amount of ink may leak, and when the ink cartridge is removed, the residual ink in the ink cartridge will flows from the ring through hole is easily formed environment pollution, contamination recording medium such as paper. 同时由于供墨针在插入或抽出墨盒出墨口内的一瞬间,会在出墨口内形成数值较大的瞬间增压或负压,导致墨水沿墨盒构件之间的缝隙外溢,或者沿墨盒内腔管路回窜入贮墨腔中,或者沿供墨针内部墨路被压入喷嘴,降低打印质量,或损坏打印头。 At the same time as the ink supply needle is inserted into or withdrawn out of the moment in the ink cartridge port formed larger value or instantaneous boost negative pressure in the ink outlet, resulting in a gap between the ink cartridge along the overflow member, or along the cartridge lumen fleeing back line ink-chamber, or is pressed into the inside along the ink supply needle of the ink passage nozzle, poor print quality, or damage to the print head.

实用新型内容本实用新型目的在于提供一种可有效缓解因供墨针插入或退出墨盒出墨口导致出墨口内腔压力急剧增大或减小的喷墨打印机墨盒。 SUMMARY The present invention aims to provide an ink-jet printer cartridges can relieve the ink supply needle because the ink cartridge is inserted into the ink outlet or exit the ink outlet results in a sharp increase or decrease the pressure lumen of.
