Abstract

An ink cartridge includes a case, a lid, and an ink feeding tube; the case contains a chamber and a ink supply flow passage is disposed at a bottom of the chamber; the ink supply passage is disposed with an inlet and an ink outlet connecting through the inlet; the lid is disposed with an opening and a connection tube and an air bulb separation room are formed at where below the opening; the air bulb separation room extends into the interior of the chamber and tightly incorporated with the inlet of the ink supply passage to form a separation cavity in relation to the ink supply passage; the connection tube is connected to one side of the air bulb separation room and provided with a connection port that allows the connection tube and the air bulb separation room to communicate each other; the ink feeding tube disposed on the other side of the air bulb separation room extends into the chamber for the ink in storage to enter into the vacuum sealed air bulb room through siphon to supply ink as needed for printing while air bulb in the chamber is inhibited from entering the air bulb separation room thus for the cartridge to deliver the best print quality.

Description

200909224 IX. Description of the Invention: [Technical Field] The present invention relates to a print inker structure for a continuous ink supply system for printing ink cartridges.尤八系指--Application [Prior Art] Please refer to the first figure, the ink used in the ink is M 9 . At the bottom of the column, there is an ink reservoir at the position of L W. When the external supplement black = sub-extension into the upper section of the ink storage tank 91, and the external ink supply tube of the field ρ replenishing the ink, the black water 诘仏 丄 丄 、 、 93 is interconnected ^.. Tonan ', , α, and the ink is infused into the ink tank 91 by the ink supply tube 80. However, in the ruler: Ink "3 When the ink enters the m 9G, the process of f 1 ^ 'gas, causing bubbles in the E storage ink inside the chamber ^ = 1 person shouted into the air supply for back pressure problem (4) Ink supply and delivery will not only increase the quality of ink printing. Only 9 can produce milk foam, which in turn affects the content of the invention. Now, the features and technical advantages of the present invention can be more clearly presented. DETAILED DESCRIPTION OF THE INVENTION The present invention provides a printing ink cartridge to solve the problem of bubbles generated in the process of water, and the '" The bubble generated in the PCT does not have / (4) m and excludes the printing, such as the printing quality. The printing ink provided by an embodiment of the present invention includes -_, a cover 200909224 body and a Ink tube, Μ: 匣 匣 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内 内Into the port and a column of bubble isolation chamber and connecting tube, 苴中 & square melon and corresponding ink supply "The ##.__$ system is extended to the interior of the 11th room (4), and the material μ is formed by the end of the f, and the Ku, SH B system is connected to one side of the rolling isolation chamber, and The connecting officer and the bubble isolation chamber form a mutual communication port of the second & +, ^, ^ m ^ π dead k, and the ink is introduced to the other side of the bubble isolation chamber and extends into the hiding room due to ; to isolate from the foam isolation room, so the indoor storage 3 is connected by the siphon phenomenon of the connecting pipe into the straight, soil, water! £ 4±L^ π ± , and the seal is sealed in the bubble isolation chamber of Gongshan Seal: two = at the same time, the indoor bubble can be suppressed and "Printing Day" achieves the best ink printing quality. 】 实 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二 二In addition, the intrinsic safety is in the heart; ii = medium f uses the relationship between the reference label and the text, the weight (four) structure.

The ink supply flow path 丨2 has the inlet end π 121 and the printing ink port 122 communicating with each other, and the body 20 has an opening 21 therein and is open at the opening A bubble isolation chamber 22 and a communication tube 23 are formed below the bubble chamber 22, and the bubble isolation chamber 22 extends toward the inside of the chamber 11 and corresponds to the ink supply passage 12 and the inlet end of the ink supply passage 1-2. 121 is further joined to form an isolation chamber, and further, the connecting portion 23 is adjacent to one side of the bubble isolation chamber 22, and the communication tube 23 has a communication port 231 adjacent to the bubble isolation chamber 22, the communication port The position of the 231 is located at an upper portion of the adjacent side wall of the bubble separation chamber 22, and the length is about the length of the communication tube 23, and two thirds of the communication tube 23 and the bubble isolation chamber 22 are connected to each other by the communication port 231. The end portion of the communication tube 23 has a suction port 232. The suction port 232 communicates with the chamber U and is adjacent to the bottom of the chamber. Further, the ink inlet tube 30 is disposed in the bubble isolation chamber 22. The other side has an ink discharge end 301 and an ink inlet end 302 which communicates with the ink discharge end 3〇1. The ink discharge end 301 extends into the lower position of the _u, and has a chamber 11 The spacing d, as shown, the spacing d is, for example, the height of the ink supply passage 12 and the ink inlet 3 0 2 Exposed to the cover 2 °. ° In addition to the above, the ink cartridge of the embodiment further includes a joint seal 40 and a cover 50, wherein the joint seal 4 is disposed on the weeping 12 Between the inlet port 121 and the bubble isolation chamber 22, to completely seal the interface between the bubble separation chamber 22 and the ink supply flow path 12, the ink flowing through the bubble isolation chamber 22 can be avoided, and the ink supply path 12 is self-supply. The inlet port 121 and the bubble isolation chamber 22 are oozing out, or the air bubbles in the chamber 11 are infiltrated from the inlet port 121 of the ink supply passage 12 and the bubble isolation chamber 22. The cover 5 is closed to the opening 21 to prevent foreign matter or air from entering the bubble separation chamber 22. 200909224 As shown in the figure, when the s body 1 needs to be filled with ink, first, the (1) setting 60 is combined with the ink feeding end 3〇2, that is, the ##1 ink is thus introduced into the ink tube 3. Enter (4) Μ, but: this loss, 2: due to the entrainment of air in the ink 'cause the ink storage of the diverticulum 11: angry: the specific gravity of the private bubble is lighter than the ink θ produces the milk bubble, (4) Guan η Gradually drifting to the ink level, and by V, when: the main wide ink, and then the head space of the fun room 11, by: in this example, the chamber n and the bubble isolation chamber two thin communication tubes 23, and Its suction port m is located at =

ί二 Thus, the ink in the E chamber 11 can still use the siphon phenomenon of the connecting tube 2 and the L bubble is scooped up, so the design can be separated from the sealed bubble trap 22/bridging communication tube 23 In the middle of the sign, the second load of the South 22, the communication with the bubble isolation chamber 22 is continuously supplied for the ink containing no bubbles, and the printing H is performed by printing the negative 2 ° to achieve the better printing quality. , soil, = 'in order to be able to _ lion difficult room u in the ink refilling process to complete the extrusion process, the ink g of this embodiment further includes a venting device 70 on the 脰 20, can be a broadcast such as sigh In the structure such as the body, the m chamber is turned into a direction; the membrane or the check valve main 11 is reversed to discharge the inside of the chamber 11 to maintain the normal back pressure in the chamber π.
