Description of the invention: [Technical field to which the invention pertains] The present invention relates to an ink guiding device, and more particularly to an ink guiding device suitable for a continuous ink supply system. [Prior Art] • In general, inkjet printers are popular among consumers because of their ease of operation and printability on inkjet media, but inkjet printers will be used for a period of time. Since the ink of the ink cartridge is exhausted, the ink needs to be replaced, and the ink cartridge carrying the ink cartridge is not properly sealed by the ejector structure on the carrier. It is easy to have gas entering the thimble structure and blocking the flow path of the ink = seriously affecting the ink supply, and even worse, the bubble entering the ink jet port will be bad n port 'to make the ink jet printer unable to perform the chest. In order to avoid repetitively dissolving the ink g from the ink holder to refill the ink and cause the bubble to enter the thimble structure, the continuous ink supply system that reuses the same ink g is used to generate D ^. The existing continuous ink supply system is external. The continuous ink supply system is provided with an ink supply container and an ink supply container, and the ink supply is connected by a pipeline: the ink g inside the solid ink printer, and the ink and the ink container are introduced by the principle of vacuum ink guiding. In the ink g, the ink supply container is visually observed for 7 hair conditions and the ink is replenished to the ink supply container in a timely manner, so that the ink supply of the ink 6 200808563 is continuously provided for uninterrupted ink supply. However, the above continuous ink supply system has many limitations and inconveniences in its use. First, the height of the ink supply container must be on the same plane as the inkjet printer, and the ink level of the ink supply container must be slightly lower than that of the inkjet printer to prevent the ink cartridge from being oversized from the ink supply container. The hydraulic pressure causes the ink to overflow from the ink outlet. However, after standing for a period of time, the ink ray often returns to the ink supply container due to the high liquid level of the ink, which not only seriously affects the state of the ink supply, but also wastes a certain amount of ink when re-using, so that the ink can be pressurized. Restore balance and smooth ink supply. Secondly, because the position of the ink supply container is concealed, the user is prone to make up the ink. When the ink of the ink supply container is used, the ink cartridge may not be properly supplied with ink, and even the ink may be blocked due to lack of ink drying. Ink mouth. Furthermore, the assembly of the ink cartridge, the ink supply container and the pipeline is complicated. If the pipeline is improperly installed, the movement of the ink cartridge carrier will be affected to reduce the printing quality, and if the pipeline is loose, the ink will leak, and the entangled pipeline is also Will affect the external appearance of the inkjet printer. However, if the ink is removed from the ink cartridge holder to refill the ink, the current ink cartridge and the ink cartridge carrier have no proper ink-breaking mechanism, so that ink leakage is easily caused to contaminate the interior of the inkjet printer. In view of this, how to develop an ink guiding device suitable for the ink cartridge holder of the continuous ink supply system, so that the ink cartridge can be taken out of the ink or replaced without leakage of ink and avoid the above-mentioned conventional defects in the ink supply by the pipeline. It is an urgent problem that needs to be solved. 7 200808563 SUMMARY OF THE INVENTION The main object of the present invention is to provide an ink guiding device for an ink cartridge bearing seat of a continuous ink supply system, which is configured to receive a column that is placed in the receiving space of the first base by using an elastic member.

The minimum cut-off area, in addition to the plunger 112, there is a connection end 1121, which is used to connect the projectile 113 to the ellipse 1131. Please refer to the first figure (b) and cooperate with the first figure (6 Ganshan 么 楚 楚 Ulc), The first picture (4) is a schematic cross-sectional view of the assembly of the brother (a). The cup is replaced by the 〜 cup 〜η. If the assembly is completed, the connection end of the column base 112 is 1121. It is fixedly connected with the elastic body ^ 110 ～ 1131, and the column base m is placed in the accommodating space of the needle holder U1 and the middle needle seat (1) is sequentially connected by the hole 131 of the connecting seat 13 and the body of the water bearing seat i After the thimble setting hole 1G on the 15 is passed through, the core portion is fixed to the ink cartridge holder r body 15 by the heart-shaped portion (1) w, and the top end nn of the needle holder π is placed inside the ink bearing holder κ and toward the ink s. In the present embodiment, the spring seat (1), the fixing portion 1113 of the needle holder 111, and the body 15 of the ink cartridge holder - 1 are fixed by a solid reading and locking. For example, it is screw-locked, 11 200808563. Any fixing method, such as direct threading or clamping, can be used in this case to fix the thimble structure u to the ink cartridge holder 1. Please read it again. In the first figure (c), when the ejector structure u is fixed to the body 15 of the ink cartridge holder 1, the plunger 112 is subjected to the elastic force of the spring 1131 and abuts against the tip of the needle holder 1 in the direction of the tip, and 112 The minimum cross-sectional area of the vertical axis is larger than the vertical axis of the housing space 1112 The most sinuous cross-sectional area, so when the spring 1131 pushes the plunger 112 such that the minimum cross-sectional area of the vertical axis of the plunger 112 is equal to any cross-sectional area of the vertical axis in the accommodating space 1112, the plunger 112 cannot continue to face. The direction of the top mi is =, and since the shape of the main plug 112 and the accommodating space 1112 are substantially substantially matched, the plunger 112 will be in close contact with the accommodating space ιι 12f at a large area near the tip end mi. The accommodating space 1112 of the sealing needle holder 111 is adjacent to one side of the top end 1U1, and in this embodiment, the taper surfaces of the two sides are matched with each other, so that the top of the plunger 112 and the column lining base 112 and a large area of contact with the closed air 1111, the thimble structure 11 can be sealed to break the ink. On the second day of the second reading (4), it is the first diagram (4) of the case. As shown in the figure, when the ink is on the body 15 of the carrier (4) carrier i to form the #ink structure, part of the female (1) of the thimble structure u is combined with the flow of the ink E 2 ' and the thimble structure u The plunger will provide a force outside the water E 2 , for example, the rigid material of the top column ^ : two and the elastic force of the spring 1131 of the structure Λ 1 , when the plunger 112 and the δ · push the elastic material of the magazine 1131 The plunger m 12 200808563 is compressed inwardly to cause the plunger ι12 to create a gap 12 in the accommodating space iii2 with the wall surface of the hub U1, that is, to form an ink guiding passage, and due to the valley portion of the magazine seat 113 The 1132 is in communication with the accommodating space m2 of the hub 111 and the sleeve end 1133 of the cymbal 113, so that the ink in the ink chamber of the ink cartridge 2 can enter the gap of the thimble structure 11 via the flow channel 22 of the ink g2. 12, flowing into the ink cartridge carrier 1 end, and then guiding the ink to the ink jet port of the ink φ 匣 carrier 1 via the receiving portion 1132 of the elastic seat 113 and the ink supply tube connected to the sleeve end 1133 (not shown) ) to complete the ink guiding action. Since the volume of the ink chamber 20 of the ink cartridge 2 is limited, after printing for a period of time, when the warning message of the low ink content of the ink g 2 appears, the user needs to be away from the thimble on the body 15 of the ink g carrier i. The ink cartridge 2 is taken out in the direction of the structure 11 to perform ink replenishment. Please refer to the first figure (4) as shown in the figure 'When the ink g carrier! The thimble structure u and the ink: when the g 2 is separated, the ink of the top of the top of the column 21 is opposite to the ejector structure u: the force of the plug 112 is gradually weakened as the ink g 2 exits the body ❿ 15 of the ink escaping workman' At this time, the plunger 112 of the thimble structure 11 is combined due to the bomb! The elastic force acts toward the top of the needle seat m! Outward direction abuts: Then ^ also 'When the spring simply pushes the plunger 112 to make the column * 112 vertical axis =, wear = equal to the needle seat (1) accommodates the empty _ inner vertical axis of the plunger 112 can not continue The yoke (1) protects the shape substantially = and because the shape of the plunger 112 and the surface of the accommodating space 1112, for example, in the present embodiment, the two are tapered to each other - so that the thimble structure u' can be tightly blocked The thimble structure 13 200808563 11 can block ink leakage. And the closing process is a thimble structure which is gradually sealed with the withdrawal of the ink cartridge 2, in other words, when the ink cartridge 2 is completely separated from the thimble structure 11, the thimble structure 11 is immediately closed. In summary, the ink guiding device of the ink cartridge bearing seat of the present invention uses an ink cartridge to provide an external force to compress the plunger of the thimble structure, so that the plunger creates a gap in the accommodating space and the wall surface of the needle seat. Thus, the ink can be inked into the ink cartridge carrier through the gaps in the ejector structure. When the ink guiding device wants to break the ink, that is, when the ink cartridge is to be taken out for ink replenishment, as the ink cartridge exits the body of the ink cartridge carrier, the external force provided by the ink cartridge abuts against the plunger in the thimble structure needle holder. The force is also weakened, so the plunger can close the receiving space of the needle seat close to the end of the top by the elastic force of the spring, so as to form the broken ink, so that the ink leakage phenomenon does not occur at the thimble structure. In this case, the value of this project is extremely industrial, and the application is filed according to law. The present invention has been described in detail by the above-described embodiments, and may be modified by those skilled in the art without departing from the scope of the appended claims. 14 200808563 [Simplified description of the drawing j: Load: the ink of the first embodiment of the present invention - the light frame of the R-type carrier = one figure (e): the system is the first - Figure _ completed schematic section - Figure (4) : This is the diagram of the force of the first part of the case - Figure (6).
