Description of the Invention: [Technical Field] The present invention relates to an ink jet printing head capable of preventing oblique ink ejection droplets, and more particularly to uniformly dispersing ink slag in a spray-off _ anti-slanting nozzle (four) ink Print the head. [Prior Art] "With the increasing popularity of personal and home (4) brains and the increasing demand for personal image output, inkjet printing devices attract consumers to buy because of their reasonable price and excellent (four) printing quality. It has become the most commonly used personal or home user, computer output printing equipment. However, if you want to have high-order output printing quality, how to effectively maintain the technology of spraying the lion's fine (four) scales. The ink-shaped device includes an ink-jet member that can store ink-jet-to-print documents along a predetermined track, and the ink-jet member includes at least a print head for controlling the ink and controlling the ink. The common inkjet printing device is based on the principle of actuation. 'It can be divided into many types' such as: pressing material (ρ_如(四), thermal bubble ennalBubble), etc. No matter what kind of inkjet printing device, it is necessary to pass the ink droplets. Extrusion of the nozzle hole is sprayed onto the printing (4). For example, please refer to the paragraph! 1 is the structure of the cross section of the printing head of the conventional thermal bubble inkjet printing device. Fine, water 1 "1,6,1〇8, heating unit 110 , 112 and - the orifice sheet is called. The ink is covered by the outer casing 1 (8), 1 〇 2', which is used to store the printing ink, the ink control chip SM06 and the inkjet control wafer (10) are formed with an ink flow path. 1285592 118, used to transfer the ink 116 stored in the ink reservoir 104 into the ink chambers (Ink Chamber) 120, 122. The inkjet control wafers 1〇6, 1〇8 can control the heating units 110, 112, when After the heating unit 11〇, 112 is heated, a small amount of ink droplets in the ink chambers 12〇, 122 can be vaporized instantaneously, and the rapid expansion after evaporation of the ink droplets causes a small amount of ink to pass through the nozzle holes 124 and 126 on the orifice sheet 114 to be printed to That is to say, the printing head 10 uses the method of thermal energy to heat a small amount of ink in the ink chambers 120 and 122 to cause bubbles to be boiled, and then pushes the ink out through the pressure of the bubbles. The advantage is that the printing speed is faster, but the disadvantage is that the ink is ejected only by pushing, the force is less concentrated, the ink is affected by the law of inertia, and the orifice sheet 114 is pulled, resulting in uneven or ink. When there is ink collapse on the orifice sheet 114, a pulling force is generated with the ink droplets ejected. The accuracy of the oblique spray is affected. The month of the month refers to Figure 2'. Figure 2 is a schematic diagram of the conventional inkjet printing device when the inkjet is correctly inked. For the sake of simplicity, Figure 2 shows a spray nozzle. The hole 2〇2 ejects the ink droplet 204 onto the document 206 to be printed. Under normal circumstances, when the ink is pushed and ejected by the ejection hole 202, the ink droplet 2G4 can be advanced in the direction and correctly sprayed to the document to be printed 2G6. However, when there is ink residue remaining in the orifice sheet, it will affect the inkjet direction of the ink droplets. Please refer to Figure 3, and Figure 3 is the inkjet printing device oblique inkjet of Figure 2. In the third figure, the ink film 3 remains on the orifice sheet 114, and when the ink droplet 2〇4 is ejected from the nozzle hole 2〇2, it is affected by the pulling force of the ink residue 3〇〇. Therefore, the traveling direction of the ink droplets is changed from the direction to the direction 302, so that the phenomenon of shooting is generated, and the document code is uniform or blurred. 1285592 In short, ^, in the conventional inkjet printing device, the ink is ejected only by pushing, and the Lili car is not bad, the ink droplet is easily affected by the law of inertia and the orifice is pulled, and the ink and money are generated. stay. Further, the recording on the orifice sheet will cause a pulling force with the ejected ink droplets, causing a oblique spray, so that the fineness of the ink jet printing device is affected, and the printing quality is reduced. SUMMARY OF THE INVENTION The main object of the present invention is to provide an ink jet print head capable of preventing oblique ink jetting. An ink jet print head capable of preventing oblique ink droplets, comprising: a water storage tank in which an ink for printing is stored; an ink flow path connected to the ink:: ' For conveying ink stored in the ink reservoir; an ink chamber connected to the ink flow path for receiving ink from the ink flow path; - a button, disposed on the side of the ink, a plurality of An orifice is formed on the orifice sheet for ejecting ink; and a plurality of first-ink-absorbing members, each of which is symmetrically formed around an orifice. [Embodiment] FIG. 4 is a bottom view of a printing head 4 of an ink jet printing apparatus according to a preferred embodiment of the present invention. In Fig. 4, a orifice piece is provided with a plurality of perforations and a plurality of ink absorbing members 4〇4. Each orifice ejects ink to print to the document to be printed. In this example, each of the ink absorbing members 4〇4胄 is a groove structure, and each ring 1285592 is wound around the corresponding spray hole 402' for adsorbing and uniformly dispersing excess ink slag sprayed from the spray hole 402 to the corresponding spray. Around the hole 4〇2. For the operation of the print head 4〇, please continue to refer to Figures 5, 6, and 7. Figure 5 is a cross-sectional view of the orifice sheet in the print head 4 of Figure 4, and Figure 6 is the print head 40. ..., ink, schematic diagram of inkjet when inspected, 帛7 is a schematic diagram of inkjet when printing head ink. In Fig. 6, the ink droplets 4〇6 are ejected from the ejecting holes 4G2 and are scattered in the direction to the document to be printed. In the seventh figure, if the law of the ink is more flexible, and the orifice sheet 400 is pulled to generate money, the invention can use the ink absorbing member 4〇4 to uniformly adsorb the excess ink in the nozzle hole 4〇2. Around, the pulling force between the ink collapse and the ink droplets can be uniformly canceled without affecting the traveling direction of the ink droplets 406. Therefore, as is apparent from Figs. 6 and 7, the present invention can prevent the print head 40 from being obliquely sprayed by the ink absorbing member (groove), thereby maintaining the accuracy of the ink jet. In contrast, in the prior art, in the prior art, the ink on the orifice sheet generates a pulling force on the ink droplets ejected from the orifices, so that the traveling path of the ink droplets is affected, and the phenomenon of oblique spraying is caused to cause the printing materials to be printed. Evenly and paste. In the thief's ground, the hair _ is formed around the nozzle hole to form (4) ink absorbing parts, so that the wrong money can be creased in the nozzle hole. In this way, the horizontal pulling force of the ink droplets ejected from the orifice can be canceled, so that the printing head can be prevented from producing a diagonal nozzle, thereby maintaining the accuracy of the ink jet. It is particularly noted that in the present invention, in order to make M+T T4, the tensor of the ink absorbing member can be offset against the ink droplets. The ink absorbing member must be symmetrically formed around a mouth, and 8 1285592 The edge of the ink absorbing member and the edge of the corresponding nozzle are also fixed to prevent uneven tension. Therefore, the ink absorbing member may also include a plurality of grooves each symmetrically formed around an orifice. Of course, the present invention may also be provided with at least one turn of the ink absorbing member in addition to the ink absorbing member to enhance the ink absorbing effect. In addition, in the ink absorbing member, a material having an ink absorbing effect may be added or used to achieve a better ink absorbing effect. Therefore, with the arrangement of the ink absorbing member of the present invention, the ink slag on the orifice sheet can be evenly distributed around a nozzle hole to prevent uneven tension between the ink slag and the ink droplet, thereby preventing oblique spray to maintain The accuracy of inkjet. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should fall within the scope of the present invention.
