Abstract

The utility model provides a printer ink box, comprising an ink storage chamber, a pressure adjusting mechanism, a sealing ring and a sealing ball; the pressure adjusting mechanism is arranged in the ink storage chamber, and a valve membrane is arranged between the front valve body and the rear valve body of the pressure adjusting mechanism; the mechanism is wholly arranged on the surface cover of the ink storage chamber, and is provided with a vent hole communicated with a blowhole on the surface cover and with the atmosphere. Owning to the function of the pressure adjusting mechanism, the printer ink box can lead the whole ink storage chamber in a negative pressure state, ensuring that ink can continuously and uniformly flow to a printing head to a greater extent when printing, meanwhile, solves the problem of the overflow of ink whenever the ink box is moved away from the printer.

Description

打印机墨盒 Printer Cartridges

技术领域 FIELD

本实用新型涉及一种打印机墨盒。 The present invention relates to a printer cartridge.

储墨腔的出墨口处设置有密封圈,密封圈的内圈处放置有一密封球,该密封球由一弹簧将其顶在密封圈的内圈处。 An ink outlet of the ink chamber is provided with a sealing ring, the inner ring is placed at a sealing ball, the ball by a spring to seal the top of the seal ring at the inner ring. 本实用新型具有以下优点:1、整个储墨腔处于负压状态;2、位于储墨腔内压力调整机构的阀膜平面面积较大,在压强恒定时,压力变大,可以更加稳定地控制负压,在更大程度上保障打印时墨水能够持续均匀地流向打印头;3、不需要多孔体的毛细吸力保证出墨,从而既增加了储墨腔的储墨量,又避免因多孔体的吸墨作用造成的墨水的浪费;4、除了出墨口的负压作用外,还新增了一种机械机构,能将密封圈内的圆孔封死,从根本上解决了在墨盒移离打印机后墨水外流的问题。 The present invention has the following advantages: 1, the whole of the ink reservoir chamber in a negative pressure state; 2, the ink reservoir is located in the larger chamber of the pressure adjusting mechanism diaphragm plane area, at a constant pressure, the pressure is increased, can be controlled more stably a negative pressure, the ink can continue to flow uniformly printed to protect the print head to a greater extent; 3, capillary attraction of the porous body is not required to ensure the ink, thereby not only increasing the ink storage amount of the ink reservoir, but also to avoid the porous body waste ink absorption due to ink; 4, except that the negative pressure of the ink outlet, but also added a mechanical mechanism, the circular seal ring sealed can solve the fundamental shift from cartridge after questions from the printer ink outflow.

附图说明 BRIEF DESCRIPTION

:图1是本实用新型的结构剖视图;图2是本实用新型的压力调整机构剖视图;图3是本实用新型结构示意图。 : FIG. 1 is a cross-sectional view of the structure of the invention; FIG. 2 is a cross-sectional view of the present invention the pressure adjustment mechanism; FIG. 3 is a schematic view of the present invention a novel structure.

1密封圈、2密封球、3弹簧、4储墨腔、5前阀体、7阀膜、8后阀体、9面盖、10出墨口、11通气孔、12空气槽、13气孔、 14凹孔、 15阀膜小圆孔储墨腔4的出墨口10处设置有密封圈1,密封圈1的内圈处放置有一密封球2,该密封球2由一弹簧3将其顶在密封圈1的内圈处。 A sealing ring, the sealing ball 2, a spring 3, the ink reservoir 4, 5 before the valve body, the valve membrane 7, after the valve body 8, the top cover 9, the ink supply port 10, vent hole 11, air slot 12, air holes 13, recesses 14, the valve membrane with a small hole 15 to the ink outlet of the ink reservoir chamber 4 is provided with a sealing ring 10 at 1, the inner ring 1 is placed at a sealing ball 2, the ball seal 2 by a spring to its top 3 in the inner ring at the 1.

当墨盒放入打印机时,打印头上的圆柱从出墨口10插入密封圈1中的圆孔内,将密封球2顶起,这时墨水可从密封圈1中间的圆孔流入打印头。 When the ink cartridge into the printer, the print cylinder head from the ink port 10 is inserted in the circular ring 1, the ball 2 will act as a seal, when the printhead ink may flow from the intermediate circular ring. 在墨水流入打印头的过程中,储墨腔4因墨水的流出会使压力降低,当压力降低到一定程度(-0.5KPA至-1.5KPA)时,与后阀体8密合在一起的阀膜7被压力差所产生的力拉向前阀体5,同时压力调整机构中的弹簧3被压缩,阀膜7中间的小圆孔15被拉离后阀体8,处于通气状态,空气从面盖9上的通气孔11经由后阀体8上的气孔13、空气槽12和阀膜7中间的小圆孔15流入储墨腔4内,从而使整个储墨腔4的压力升高,当升高到一定程度后,阀膜7被压缩的弹簧3本身所具有的弹力又推向后阀体8,使阀膜7中间的小圆孔15重新被弹簧3顶在后阀体8上的凹孔14内,重新处于密封状态。 During ink flows into the printhead, the ink chamber 4 due to the reduced pressure of the ink will flow out when the pressure is reduced to a certain extent (, -1.5 kPa to -0.5 kPa), the valve body 8 and the valve together adhesion 7 after the membrane 15 is pulled away from the valve differential pressure generated force pulled forward valve body 5, while the pressure adjusting mechanism is compressed spring 3, the intermediate valve film 7 small hole 8, in the ventilation state, air from after the surface of the cap 9 via the vent hole 11 on the valve body 813, the valve membrane 12 and the groove 7 in the middle of the air flow into the small hole 15 of the ink reservoir 4, so that the entire pressure of the ink storage chamber 4 is increased, when raised to a certain extent after the valve membrane 7 compressed spring 3 itself has an elastic force toward valve body 8 and the diaphragm 7 in the middle of the small hole 15 is spring 3 again after the valve body 8 in the recesses 14, again in a sealed state. 在继续打印的过程中,储墨腔4内的压力又重新降低,从而使后阀体8与阀膜7之间的间隙再次产生,空气又流入储墨腔4内。 In the printing process continues, the pressure in ink chamber 4 is lowered again, so that the gap between the valve body 8 and the diaphragm 7 is generated again, and the air flows into the ink chamber 4. 在整个打印过程中,该过程周而复始,直到打印状态结束。 In the entire printing process, this process again and again until the end of the print status.

当墨盒移离打印机时,密封球2在弹簧3弹力的作用下将密封圈1的圆孔堵上,该作用力与出墨口内的负压作用力一起,保证墨水无法流出墨盒外。 When the ink cartridge is moved away from the printer, the sealing ball 2 by the spring force of the seal ring 3 is a circular hole plug, the biasing force of the negative pressure force in the opening with the ink, the ink can not flow out of the ink cartridge to ensure.
