Description of the invention: [Technical field to which the invention pertains] In particular, the use of air pressure flats is a continuous ink supply system for a continuous ink supply system. [Prior Art] With the development of computer multimedia technology, the printing output device is not only for: text output 'but becomes a device that can simultaneously output the text for text or digital photo output, among which inkjet printer The machine has the advantages of low price, easy operation, and can be printed on a variety of inkjet media such as paper, photo paper, etc. It can be said to be an economical and effective color printing output device. + However, the ink E price of the inkjet printer is still high, the price of the general black ^ with color ink E is almost the purchase - Taiwan printer: the price, and the ink capacity of the ink cartridge is limited, about ten Even less, if: a large number of print output, in order to reduce the cost of use, while avoiding the exhaustion of ink and the need to replace the ink S caused by the discontinuity of the printing "color difference and other issues" continuous ink supply system . The conventional continuous ink supply system can use the pump or siphon to guide the ink from the outer ink cartridge to the ink cartridge installed in the printer by using the ink supply tube. The main principle is to print on the ink of the printer. While the medium-to-head inkjet head continuously supplies ink, the ink cartridge also draws the same amount of ink from the outer ink cartridge to replenish the balance, that is, how much ink is delivered to the inkjet head, and how much ink is immediately replenished. The continuous ink supply system using the pump method mainly sucks the ink from the outer ink cartridge into the ink cartridge by means of the pump pressurization, and although the effect of the ink guide can be achieved, the price of the pump is expensive. It must be combined with other devices to control the operation of the pump, which will increase the manufacturing cost, and must be driven by electricity to drive the pump. Therefore, the cost of control is relatively increased, and it is difficult to use the pump. The corner of the ink cartridge, so the outer ink cartridge is prone to residual ink, which indirectly causes waste of ink. In addition, due to the complexity of the pump structure, it is necessary to regularly clean, repair and maintain. Moreover, once the pump fails, it is time-consuming to repair, which will make the continuous ink supply system unable to supply ink during the maintenance period, thus affecting the operation of the inkjet printer and its printing quality. In view of this, how to develop a continuous ink supply system that can improve the balance of the above-mentioned conventional techniques using air pressure balance is an urgent problem to be solved.

In addition, in order to further prevent the ink supply f 13 from being blocked by the gravity after the long-term use, the second opening 142 of the hollow sleeve 14 is blocked to block the ink supply passage, the hollow sleeve 14 may be provided with a projection 143. And is connected to the inner wall of the hollow sleeve 14. In the embodiment, the protrusion 143 is adjacent to the second opening 142' of the hollow sleeve 是以 is the wall of the second nozzle 132 of the ink supply tube 13. The protrusion 143 of the hollow sleeve 14 can be abutted against the second opening 142 of the hollow sleeve 14 and the second opening 142 of the hollow sleeve 14 can be prevented from falling. The height difference h between the nozzle 132 and the bottom of the ink reservoir 122 controls the minimum ink discharge amount of the ink supply container η. Of course, the protruding portion 143 of the hollow sleeve 14 is not limited to being disposed adjacent to the second opening 142, and the position is set between the first opening 141 and the second opening 142 by using the ink of the ink cartridge 21351351. Appropriate adjustments. In addition, the projections 143 also have a plurality of embodiments, such as flanges or bumps, but not limited thereto, and any of the second openings 142 of the hollow sleeve 14 can be prevented from being slid by the gravity of the ink supply tube 13 due to gravity. The device or design can be used in this case. Please refer to the third figure, which is a partial schematic view of the first preferred embodiment of the present invention. As shown, the ink supply tube 13 is sleeved in the hollow sleeve 14 from the first opening 141 at the top of the hollow sleeve 14, and the second opening 142 of the hollow sleeve 14 is substantially adjacent to the bottom of the hollow sleeve 14. The outer wall allows ink from the ink supply container 11 to flow through the second opening 142 of the hollow sleeve 14 into the ink reservoir 122 of the ink cartridge 12 (as shown in the second figure). Referring to the second figure and in conjunction with the third figure, since the hollow sleeve 14 has a projection 143 that can abut against the ink supply tube 13, the second nozzle 132 of the ink supply tube 13 and the ink cartridge 12 can be stored. The bottom of the ink tank 122 has a height difference h, which can prevent the second nozzle 132 of the ink supply tube 13 from coming into contact with the bottom of the ink storage tank 122, so that the ink supply container 11 cannot be discharged, and the ink φ can be hollowed out. The second opening 142 of the sleeve 14 smoothly flows into the ink reservoir 122 of the ink cartridge 12. Please refer to the fourth figure, which is a schematic view showing the state of use of the continuous ink supply system of the first preferred embodiment of the present invention. As shown, during use, when the level of ink absorbed by the foam 123 disposed in the ink reservoir 122 (as shown in the second figure) is higher than the second nozzle 132 of the ink supply tube 13, due to The internal and external pressures are balanced, so that the ink in the ink supply container 11 does not flow from the ink supply tube 13 to the ink storage tank 122, at which time the continuous ink supply system 1 is in a state in which the ink supply is stopped. On the contrary, when the ink cartridge 12 is continuously used, the ink level absorbed by the bubble 11 1351351 in the ink reservoir 122 drops below the height of the second nozzle 132 of the ink supply tube 13 'because the internal and external pressures are uneven, That is, the pressure inside the ink cartridge 12 is lower than the pressure inside the ink supply container 11, so that the ink in the ink supply container U will flow downward due to gravity, that is, the ink outlet 111 from the ink supply container u passes through the ink supply tube 13. The first nozzle 131 enters the ink supply tube 13 and then flows into the ink reservoir 122 of the ink cartridge 12 through the second opening 142 of the hollow sleeve 14 to perform the ink filling operation while utilizing the venting opening 112 of the ink supply container n. Breathing to maintain the air pressure balance until the liquid level of the ink absorbed by the ink reservoir 122 in the ink cartridge 12 rises to be flush with the second nozzle 132 of the ink supply tube 13, since the internal and external pressures are again balanced, The ink in the ink container u cannot continue to flow into the ink storage tank 122, that is, the ink supply is stopped (as shown in the fifth drawing). Similarly, when the user continues to use the ink g 12 for printing such that the ink level in the ink reservoir 122 is lower than the height of the second nozzle 132 of the ink supply tube 13, due to the ink supply container 11 and the ink maker 12 The pressure difference is again generated, and the ink in the ink supply container 11 flows from the ink supply tube 13 to the ink storage tank 122 due to the difference in gravity and the home force, until the ink level absorbed by the foam (2) of the ink storage tank 122 is absorbed. Once again, it is flush with the second nozzle 132 of the ink supply tube 13 so that it can be known that the present invention can utilize gravity to control the flow direction of the ink and utilize the principle of air-dust balance to perform continuous ink supply and capillary action of the ink supply #13. Repeatedly, the ink level of the ink reservoir 122 of the ink reservoir 12 is maintained at the same height as the second nozzle 132 of the ink supply tube 13 at any time to prevent the ink in the ink reservoir 122 from being exhausted and causing printing. Continuous or color private differences. 12 丄丄 In addition, 'because the ink supply tube 13 is separated from the hollow sleeve 14', the manufacturer can call the position of the st 13 inside the hollow sleeve 14 by means of the method (4), that is, adjust the second position of the ink supply tube 13 The position of the nozzle 132 between the first opening (4) and the projection 143 of the hollow sleeve is adjusted to match the amount of ink used to adjust the amount of ink discharged from the ink supply container u. For example, when the second nozzle 132 of the ink supply tube 13 is closer to the first opening 141 8 of the hollow sleeve, the height difference between the second tube 132 and the bottom of the ink reservoir/ink 122 of the ink cartridge 12 is h. Larger, and the ink level absorbed by the bubble 123 in the ink reservoir 122 has the characteristic of continuously maintaining the flatness of the second nozzle 132 of the ink supply tube 13, so that the ink reservoir 122 of the ink g 12 will be in a The ink level is high. On the other hand, if the second nozzle 132 of the ink supply member 13 is closer to the projection 143 of the hollow sleeve, the height difference h between the second nozzle 132 and the bottom of the ink reservoir 122 is small, and the ink reservoir is small. The liquid level absorbed by the foam 123 in 122 has a characteristic of continuously maintaining flush with the second nozzle 132 of the ink supply tube 13, so that the ink reservoir 122 of the ink 12 is in a state of low ink level. When the ink E 12 is used at a low frequency or is not used for a long time, the height of the bottom portion of the first ink port 432 of the ink sleeve 12 and the ink reservoir 122 of the ink cartridge 12 may be utilized. The difference h is used to control the minimum ink level of the ink storage tank 122, that is, to control the ink supply container 11 to have a minimum ink discharge amount, so that the ink storage tank 122 maintains a certain amount of ink, thereby preventing the ink cartridge 12 from being dried due to ink drying. The ink jet head (not shown) of the ink cartridge 12 blocks the state in which the ink cartridge 12 cannot be used any more. Therefore, the amount of ink of the ink cartridge 12 can be adjusted by the user to adjust the position of the ink supply tube 13 between the first opening 141 and the second opening 142 of the hollow sleeve 14 of the 13 1351351 to adjust the continuous ink supply system 1 The amount of ink discharged from the ink supply container 11. In summary, the present invention utilizes the principle of gravity to position the ink supply container relatively above the ink cartridge, which facilitates the user to observe the remaining amount of ink in the ink supply container, so as to facilitate the replenishment of the ink in the ink supply container at any time, and The ink can be actively flowed from the ink supply container to the ink storage tank of the ink cartridge to replace the conventional ink supply system for supplying ink to the pump, thereby reducing the cost of manufacturing and controlling the continuous ink supply system; Using the principle of air pressure balance, the ink level absorbed by the foam in the ink reservoir of the continuous ink supply system can be maintained at the same level as the second nozzle of the ink supply tube, and with the ink The use of the amount of continuous and dynamic ink replenishment, so that the ink does not have the lack of ink, can reduce the inconvenience of the conventional continuous ink supply system using the pump; in addition, the case can also be seen by the user The requirement of the amount of ink is adjusted by adjusting the position of the second nozzle of the ink supply tube between the first opening and the protruding portion of the hollow sleeve, and adjusting the ink supply of the ink supply container by using the principle of air pressure balance The function of the CISS better by complete, so this case valuable industry, the Yuan to apply the 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.
