一种墨盒用压力控制器及包含该压力控制器的墨盒 An ink cartridge comprising an ink cartridge with a pressure controller and the pressure controller

技术领域 FIELD

[0001] 本实用新型涉及一种墨盒用压力控制器及包含该压力控制器的墨盒。 [0001] The present invention relates to an ink cartridge comprising an ink cartridge with a pressure controller and the pressure controller. 背景技术 Background technique

[0002] 喷墨打印机,其打印方式通常是由用于容纳墨水的墨盒提供墨源,经由相应的墨水流动通道将墨水输送至记录头中,并在打印信号的驱动下将墨水从记录头上设置的喷嘴喷射至纸张等记录介质上,来完成字符或图形的记载。 [0002] The inkjet printer used in the printing method is usually to provide an ink cartridge accommodating the ink source, the ink supply to the recording head via the respective ink flow passage, and the signal driving the printing ink from the recording head, jet nozzles provided to a recording medium such as paper, to complete characters or graphics is described.

[0003] 早期,作为供应记录头墨水的墨盒,主要是通过在储墨腔中放置海绵体以控制墨盒内部的负压,但是由于海绵体的体积较大,占据储墨腔中较大的容积,使得储墨容积变小,且海绵体自身毛细力作用下也会造成墨盒内部残墨较多。 [0003] Early on, as the recording head an ink supply cartridge, primarily by placing the sponge in the ink reservoir to control the negative pressure inside the cartridge, but due to the larger volume of the sponge, the ink storage chamber occupies a larger volume , so that the volume of the ink tank becomes small, and the capillary force of the sponge by its own will cause more residual ink inside the ink cartridge.

[0004] 鉴于此,越来越多厂家都是通过在墨盒中设有单向阀机构来维持墨盒储墨腔内的负压状态,如此,既可降低残墨量,也能增加墨盒的储墨容积。 [0004] In view of this, manufacturers are more and more by the check valve mechanism is provided to maintain the negative pressure in the ink cartridge storage state of the ink cartridge chamber, thus, can reduce the amount of residual ink, the ink tank cartridge can be increased ink volume. 其中,又以采用薄膜阀的方式较多,即阀机构设有一阀座及阀膜(即阀芯),且阀座上设有数个阀孔,阀膜覆盖在阀孔上方并可根据其两侧的压力差而靠近或离开阀孔,从而关闭或打开其中的墨水流路,如此即可稳定地控制墨盒内部的负压,稳定地供给墨水至出墨口。 Wherein the thin film valve again more ways, i.e., the valve mechanism is provided with a valve seat and a valve membrane (i.e. the valve body), and is provided with a plurality of holes on the valve seat, the valve membrane covering the valve hole at the top thereof and in accordance with two difference in the pressure side towards or away from the valve hole, thereby closing or opening the ink flow path therein, so can stably control the negative pressure inside the ink cartridge, ink is stably supplied to the ink outlet. 显然,在墨盒未进行打印时或阀膜两侧压差未达到预定值时,阀膜均与阀座上除阀孔外的壁面紧密配合。 Obviously, when a print cartridge is not performed or the pressure difference across the diaphragm does not reach the predetermined value, the diaphragm and the wall are a tight fit on the valve seat in addition to the valve bore.

[0005] 但是,由于制造误差,容易造成阀膜的平面不平整,在安装到阀机构后,与阀座的壁面之间容易形成缝隙,则当墨盒灌注墨水后,阀机构一侧的墨水容易泄漏到其另一侧,即阀两侧之间是连通的,则在两侧之间难以形成压力差,即无法控制墨盒内部的负压。 [0005] However, due to manufacturing error, likely to cause unevenness valve film plane, after installing the valve mechanism, a valve seat between the wall surface of the slit and is easily formed, when the ink cartridge after the ink filling, the ink side of the valve mechanism is easy leaking to the other side thereof, i.e. between the two sides of the valve is in communication, between the two sides is difficult to form a pressure difference, i.e. negative pressure inside the ink cartridge can not control.

[0043] 此外,如图5所示,上述阀机构中,为了防止储墨腔侧与出墨口侧的压力过大而使圆盘部851发生较大的变形而带动杆状部852最终脱离通孔842,优选地,在本实施例中,在杆状部852上设有一环状的限制部853,且该限制部853的直径大于通孔842的直径,因此, 在杆状部852受到压力差作用而向上移动一定距离后,限制部853表面与通孔842周围的壁面抵接,限制杆状部852继续向上运动,此时,圆盘部851已偏离阀孔841,墨水流动通道已打开。 [0043] Further, as shown in FIG. 5, the valve mechanism in order to prevent the pressure in the ink storage chamber side and the port side of the ink is too large so that a large deformation occurs disc portion 851 to drive the rod out of the final portion 852 through holes 842, preferably, in the present embodiment, it is provided with an annular limiting portion 853 on the rod portion 852, and the restriction diameter 853 is larger than the diameter of the through hole 842, and therefore, the rod portion 852 by after the pressure difference moves upward a certain distance, limiting wall surface portion 853 surrounding the through hole 842 abuts to restrict further upward movement of the rod portion 852, at this time, the disc portion 851 has deviated from the valve hole 841, the ink flow passage has turn on. 限制部853与圆盘部851之间的距离可根据两侧的压力差等不同条件进行限定, 不在本实用新型的讨论范围内。 The distance between the restriction portion 853 and the disk portion 851 may be defined according to different conditions and poor pressure on both sides, it is beyond the scope of the invention discussed.

[0044] 此外,在墨水入口82与阀腔83之间的墨水流动通道上还设有一滤网,用于过滤进入腔室部件8的墨水的杂质与气泡,防止杂质或气泡经由墨水而输送至打印机的打印头中而造成喷嘴堵塞或打印断线。 [0044] Further, the ink in the ink flow path between the inlet 82 and the valve chamber 83 is also provided with a filter for filtering impurities into the chamber of the bubble member 8 of the ink, to prevent air bubbles or impurities via the ink is transported to the printhead in the printer and print disconnection or nozzle clogging.

[0045] 图6a及图6b为上述墨盒用压力控制器的墨水流动状态示意图,即阀机构的储墨腔侧与出墨口侧之间墨水流动状态示意图。 [0045] Figures 6a and 6b is a schematic view of a flow state of the ink cartridge with a pressure controller, i.e., a schematic flow of ink between the ink reservoir side of the ink outlet side of the valve mechanism state. 如图6a所示,当墨盒1未开始使用时,阀机构8的储墨腔侧与出墨口侧之间的压力平衡,圆盘部851会覆盖在上述数个阀孔841上,封闭两侧之间的墨水流动通道。 , When the ink cartridge 1 is not started, the pressure difference between the ink chamber side of the ink outlet side of the valve mechanism 8 is balanced, disk portion 851 will be covered on the number of valve bore 841 to close both Figure 6a an ink flow path between the side. 如图6b所示,墨盒1开始进行打印动作时,导气孔6上方的导气膜被撕开,即导气孔6与外部大气连通,与此同时,出墨口5附近的墨水被消耗,则储墨腔侧与出墨口侧之间存在一定的压差,随着墨水的消耗,压差越来越大,直至其增加到预定值时,上述阀芯85的圆盘部851发生弹性形变而偏离阀孔841,即使得储墨腔侧与出墨口侧之间的流动通道连通,墨水从储墨腔侧经由阀孔842而流动至出墨口侧,并从出墨口侧经由墨水出口82而补充至出墨口5处并继续供应至打印头,而且,此时外部大气会补充至储墨腔4中,以保持储墨腔4中的压力维持在恒定的范围内。 When shown in Figure 6b, the ink cartridge 1 to start the printing operation, the air guide film above the guide hole 6 is torn, i.e., the guide holes 6 communicates with the outside atmosphere, at the same time, the vicinity of the ink supply port 5 of the ink is consumed, It exists between the ink chamber side of the ink outlet side of a pressure differential, as the ink consumption, increasing pressure, until it is increased to a predetermined value, the valve element 85 and the disk 851 is elastically deformed It deviates from the valve hole 841, even if the flow path between the ink reservoir chamber side have the ink outlet side communicates with the ink from the ink storage chamber flows through the valve hole side to the ink outlet side 842, and through the ink from the ink outlet side supplementary outlet 82 to the ink outlet 5, and continue to supply to the print head, and, at this time will be added to the external atmosphere ink chamber 4 to maintain the pressure in the ink chamber 4 is maintained within a constant range. 此动作反复进行,直到储墨腔4中墨水消耗完毕为止。 This operation is repeated until the consumption of the ink in the ink storage chamber 4 is completed so far. 显然,采用上述墨盒用压力控制器,尤其是其中的阀机构,可以控制稳定的墨水补充量,使储墨腔4中的压力处于比较恒定的状态,在很大程度上保证打印时墨水能够持续、稳定地流向打印头。 Clearly, the ink cartridge with a pressure controller, in particular the valve mechanism can be stably controlled replenishment amount of ink, so that the pressure in the ink chamber 4 at a relatively constant state, to a large extent upon printing ink can continue to ensure that and stable flow of the print head.

[0046] 由上述描述可知,在墨盒1制造完成而未使用时,整个墨盒1都是充满墨水,则阀腔83中自然也充满墨水;在墨盒1使用时,由于墨水出口82是设置在重力方向上阀腔的最高点处,即墨水出口82此时是高于阀芯85最高点而设置,则不管墨水怎么向外流动,总能保证阀腔83中充满墨水;即不管是在墨盒1使用时或是在未使用时,墨水总是会充满阀腔83,直到墨水被消耗完。 [0046] From the above description, when manufacturing is completed without the use of the ink cartridge 1, the entire cartridge 1 is filled with ink, the valve chamber 83 is also filled with ink NATURAL; when used ink cartridge 1, since the ink outlet 82 is disposed in a gravity at the highest point in the direction of the valve chamber, i.e. the ink outlet 82 at this time is higher than the highest point of the valve body 85 is provided, regardless of how ink flows out, always ensure that the valve chamber 83 filled with ink; i.e., whether the ink cartridge 1 or when not in use, will be full of ink when the valve chamber 83 is used until the ink is consumed. 因此,在圆盘部851由于制造公差无法与阀座84的周围壁面紧密贴合而使得圆盘部851与阀座84壁面之间存在缝隙,从而造成储墨腔侧与出墨口侧之间彼此连通,无法通过压力差而控制阀机构的开/关时,采用上述结构,即可利用上述阀腔84中的墨水的表面张力作用而将上述缝隙密封,使得储墨腔侧与出墨口侧之间相互分隔,只有两者之间的压力差达到预定值时,才会彼此连通而使墨水流动。 Thus, the disc portion 851 due to manufacturing tolerances can not be in close contact with the valve seat 84 of the peripheral wall such that a gap exists between the disc portion 851 and the wall surface of the valve seat 84, thereby causing the side between the ink chamber and the ink outlet side when communicating with each other, the valve mechanism can not be controlled on / off by a pressure difference, the above-described structure, the sealing of the slit to the valve action of the surface tension of the ink chamber 84, so that the ink storage chamber and the ink outlet side between the side separated from each other, only the pressure difference therebetween reaches a predetermined value, the ink will flow communication with each other. 显然,将墨水出口82设置在重力方向上阀腔的最高点处的位置上,才能保证墨水总是充满整个阀机构,从而保证阀的正常动作,稳定地供应墨水至打印头。 Obviously, the ink outlet 82 is provided at a position at the highest point in the direction of gravity on the valve chamber, in order to ensure that the ink always fills the entire valve mechanism, thus ensuring the normal operation of the valve, the ink is stably supplied to the print head.

[0047] 通常,墨盒用压力控制器通过第一定位机构和第二定位机构而装配在墨盒中,其中,如图3所示,第一定位机构设置在墨盒用压力控制器的插入方向上,以将墨盒用压力控制器在其插入方向上固定。 [0047] Generally, the pressure controller with the cartridge assembled by first positioning means and second positioning means in the ink cartridge, wherein, as shown, the first positioning means disposed in the insertion direction of the ink cartridge with a pressure controller 3, in the ink cartridge in the insertion direction is fixed by a pressure controller. 在本实施例中,优选地,第一定位机构为设置在腔室部件8的侧壁上的楔形块86,当墨盒用压力控制器插入墨盒1时,上述楔形块86与设置在储墨腔4的筋条上的卡槽41相配合,使墨盒用压力控制器在其插入方向上被固定。 In the present embodiment, preferably, the first positioning means is disposed on a side wall of the chamber member 8 of the wedge block 86, when the ink cartridge is inserted into the ink cartridge 1 with the pressure controller, the wedge block 86 provided above the ink chamber the slot 41 of the rib cooperates with the ink cartridge so that the pressure controller is fixed to the insertion direction thereof. 第二定位机构设置在与墨盒用压力控制器的插入方向相垂直的方向上,以将墨盒用压力控制器在上述垂直方向上固定。 Second positioning means disposed in the cartridge insertion direction by the pressure controller in a direction perpendicular to the ink container by the pressure controller is fixed to the vertical direction. 在本实施例中,优选地,第二定位机构为设置在腔室部件8的底壁上向外突出的中空圆柱87,且上述中空圆柱87中间设有一柱状部88,该中空圆柱87及柱状部88与设置在出墨口5上方的突起51配合以固定墨盒1,其中,柱状部88的外径与突起51的内径相当,突起51的外径与圆柱86的内径相当,则当墨盒用压力控制器插入墨盒1时,突起51被夹持在圆柱87与柱状部88之间,从而稳定地将墨盒用压力控制器在其垂直方向上被固定。 In the present embodiment, preferably, the second positioning means is provided on the bottom wall of the chamber member 8 outwardly projecting hollow cylinder 87, and the hollow cylinder 87 is provided with an intermediate cylindrical portion 88, the hollow cylinder 87 and a columnar portion 88 is provided with a projection 51 above the ink outlet 5 fixed with the ink cartridge 1, wherein the outer diameter of the cylindrical portion 88 to the inner diameter of the protrusion 51 relatively, the outer diameter of the inner diameter of the cylindrical projection 51 of 86 equivalent, when the ink cartridge 1:00 pressure controller inserted into the ink cartridge, the projection 51 is sandwiched between the cylinder 87 and the columnar portion 88, whereby the ink cartridge is stably secured in its vertical direction by a pressure controller. 此外,中空圆柱87的内侧面设有一定的锥度,用于引导上述突起51与其配合,并且具有一误差吸收的作用,即即使上述突起51存在制造公差,其同样可被引导装入。 Further, the inner surface of the hollow cylinder 87 is provided with a certain taper, for guiding the protrusion 51 cooperating therewith, and has a function of absorbing an error, i.e., even if the manufacturing tolerances of the projection 51, which likewise can be guided loaded.

[0048] 明显地,从三维空间而言,墨盒用压力控制器的插入方向相当于Z轴,而垂直方向则相当于XY平面,由上述描述可知,墨盒用压力控制器在Z轴和XY平面都得到固定,表示其在X、Y、Z三个方向都不会发生移动,因此,不管盒体2与面盖3采用何种焊接方式,如振动焊接等,所带来的振动都不会使墨盒用压力控制器发生偏移或位移,保证其与墨盒1之间的良好连接方式。 [0048] Obviously, from the three-dimensional space, the pressure controller with the cartridge inserting direction corresponds to the Z-axis, while the vertical direction corresponds to the XY plane, can be seen from the above description, the ink cartridge with a pressure controller in the XY plane and the Z axis have been fixed, it will not be moved expressed in X, Y, Z three directions, therefore, regardless of the case body 2 and cover 3 which face welding, vibration welding or the like employed, the vibration will not be brought the ink container is offset or displaced by pressure controller, to ensure a good connection between the ink container 1 with.

[0049] 如图如所示,腔室部件8的流动出口14设置在上述柱状部88上,即从墨盒用压力控制器流出的墨水经由流动出口14即可输送至出墨口5中,如此设置可简化墨盒1结构。 [0049] As shown in FIG, 14 the outlet flow chamber member 8 provided on the columnar portion 88, i.e., flows from the ink cartridge via an ink flow outlet pressure controller 14 can be delivered to the ink outlet 5, so 1 is provided to simplify the structure of the ink cartridge.

[0050] 显然,从上述描述可知,墨盒用压力控制器与墨盒1是分开制件,即墨盒用压力控制器是独立制件,其可制成一通用标准件,可拆卸地装配在不同型号的墨盒上,图7所示为将墨盒用压力控制器用于另一型号墨盒的结构示意图,显然,采用上述分体式的墨盒用压力控制器,可减少生产制造成本,并且在进行墨盒回收时,即使墨盒的外部受到损坏,其也可拆卸后进行回收,有利于环境保护。 [0050] Obviously, from the above description that, with the ink cartridge 1 with the pressure controller is separate parts, i.e., the pressure controller with the ink container are independent parts, which parts can be made of a common standard, removably fitted in different models on the ink cartridge, the structure shown in FIG. 7 is a schematic view of another type of cartridge for an ink cartridge with a pressure controller, obviously, the above-described split-type ink cartridge with a pressure controller, can reduce manufacturing costs, and recovery is performed when the ink cartridge, even outside the ink container damaged, which is also removable after recovery, are environmentally friendly.
