See also Fig. 4, it is the user mode schematic diagram of the continuous ink-supply system of the present invention's first preferred embodiment.As shown in the figure, in use, when the continuous 123 ink absorbed liquid levels of the bubble in being arranged at ink duct 122 (as shown in Figure 2) are higher than second mouth of pipe 132 of ink supply pipe 13, because internal and external pressure balance, therefore the ink in the ink-feeding container 11 just can not flow in the ink duct 122 from ink supply pipe 13, and this moment, continuous ink-supply system 1 just was in the state that stops ink supply.Otherwise, when ink cartridges 12 continues to use the continuous 123 ink absorbed liquid levels decline of the bubble that causes ink duct 122 in and when being lower than the height of second mouth of pipe 132 of ink supply pipe 13, because external and internal pressure inequality, that is the pressure of ink cartridges 12 inside is lower than the pressure of ink-feeding container 11 inside, therefore the ink in the ink-feeding container 11 just can be taken advantage of a situation toward dirty because of gravity, promptly enter ink supply pipe 13 via first mouth of pipe 131 of ink supply pipe 13 from the ink outlet port 111 of ink-feeding container 11, second opening 142 by hollow sleeve 14 flows in the ink duct 122 of ink cartridges 12 again, to mend the action of China ink, utilize the air-vent 112 of ink-feeding container 11 ventilative simultaneously to keep air pressure balance, until the continuous 123 ink absorbed liquid levels of bubble rise to when flushing with second mouth of pipe 132 of ink supply pipe 13 in the ink duct 122 of ink cartridges 12, because external and internal pressure is balance once again, and the ink in the ink-feeding container 11 just can't continue to flow in the ink duct 122, promptly stops ink supply (as shown in Figure 5).
In like manner, when the user continues to use ink cartridges 12 to print the ink level that causes in the ink duct 122 to be lower than the height of second mouth of pipe 132 of ink supply pipe 13, owing to produce pressure differential once again between ink-feeding container 11 and the ink cartridges 12, ink in the ink-feeding container 11 just can flow to ink duct 122 from ink supply pipe 13 because of gravity and pressure differential, continuous 123 ink levels that absorbed of bubble in ink duct 122 are once more with till second mouth of pipe 132 of ink supply pipe 13 flushes, hence one can see that, the present invention can utilize the flow direction of GRAVITY CONTROL ink, and the principle of utilizing air pressure balance is carried out the pressure drop that the capillarity of the ink supply of continous way and ink supply pipe 13 causes, it is contour that the ink level of the ink duct 122 of ink cartridges 12 is kept at any time with second mouth of pipe 132 of ink supply pipe 13, exhausts and cause problems such as printing discontinuous or heterochromia with the ink in the ink duct 122 of avoiding ink cartridges 12.
In addition, because ink supply pipe 13 is to separate setting with hollow sleeve 14, therefore the user can adjust the position of ink supply pipe 13 in hollow sleeve 14 inside in the mode of pull voluntarily, that is second mouth of pipe 132 of adjusting ink supply pipe 13 is regulated the China ink that of ink-feeding container 11 and is measured in first opening 141 of hollow sleeve 14 and the position between the protuberance 143 with the demand that cooperates the ink consumption.For example, when second mouth of pipe 132 of ink supply pipe 13 is adjacent to first opening 141 of hollow sleeve 14, because second mouth of pipe 132 is bigger with the difference in height h of ink duct 122 bottoms of ink cartridges 12, and continuous 123 the ink absorbed liquid levels of bubble have and continue to keep the characteristic that flushes with second mouth of pipe 132 of ink supply pipe 13 in the ink duct 122, so the ink duct 122 of ink cartridges 12 can be in the higher state of an ink level.
Otherwise, when if second mouth of pipe 132 of ink supply pipe 13 is adjacent to the protuberance 143 of hollow sleeve 14, because second mouth of pipe 132 is less with the difference in height h of ink duct 122 bottoms, and continuous 123 the ink absorbed liquid levels of bubble have and continue to keep the characteristic that flushes with second mouth of pipe 132 of ink supply pipe 13 in the ink duct 122, therefore the ink duct 122 of ink cartridges 12 can be in the lower state of an ink level, lower or when not using for a long time when the frequency of utilization of ink cartridges 12, second mouth of pipe 432 that the present invention also can utilize the protuberance 143 that is resisted against hollow sleeve 14 and the difference in height h of ink duct 122 bottoms of ink cartridges 12 control the minimum ink level of ink duct 122, that is control ink-feeding container 11 has minimum and goes out China ink amount, make ink duct 122 keep a certain amount of ink, can avoid ink cartridges 12 to cause the ink gun (not shown) of ink cartridges 12 to block the situation that makes ink cartridges 12 continue to use because of ink is dry.But thus it, the ink consumption of user's visible ink casket 12 is adjusted the position of ink supply pipe 13 in 142 of first opening 141 of hollow sleeve 14 and second openings voluntarily, goes out the China ink amount with the ink-feeding container 11 of regulating continuous ink-supply system 1.
In sum, the present invention utilizes the principle of gravity, ink-feeding container is relatively arranged on the ink cartridges, can be convenient to the user and observe ink remaining amount in the ink-feeding container, in order to the ink that replenishes at any time in the ink-feeding container, and make ink be able to initiatively down flow in the ink duct of ink cartridges, to replace existing continuous ink-supply system, so can reduce the cost of making and controlling continuous ink-supply system with group's Pu ink supply from ink-feeding container; In addition, the present invention utilizes the principle of air pressure balance, the continuous institute of bubble ink absorbed liquid level in the ink duct of continuous ink-supply system ink inside casket can be kept at any time flush height with second mouth of pipe of ink supply pipe, and continue dynamically to replenish ink with the use amount of ink, make ink cartridges be unlikely to have the anxiety of ink scarcity, can reduce the existing not convenient property of utilizing the continuous ink-supply system of group's Pu start; Moreover, the also visual user of the present invention is to the demand of the ink consumption of ink cartridges, second mouth of pipe by adjusting the ink supply pipe is in first opening of hollow sleeve and the position between the protuberance, and the principle of utilizing air pressure balance is regulated the black amount of going out of ink-feeding container, it is complete that the function of continuous ink-supply system is more attained, so the present invention has the value of industry.
