It can be understood that, in the ink cartridge structure 100, by providing the buffer chamber 14 with an elongated shape, the buffer chamber 14 communicates with the ink storage chamber 11 through the ink through hole 141, the ink supply chamber 12 communicates with the buffer chamber 14 through the communication hole 111, so that the ink storage chamber 11 is separated from the ink supply chamber 12 through the buffer chamber 14, and when the printer is in operation, under the action of suction force and ink gravity, the ink in the ink supply chamber 12 is taken from the buffer chamber 14, so that the ink in the buffer chamber 14 and the ink supply chamber 12 can be relatively kept in a saturated state; it can be understood that, the buffer chamber 14 and the ink supply chamber 12 relatively kept in a saturated state can avoid the influence of the liquid level shaking in the buffer chamber 14 or the ink storage chamber 11 on the ink supply chamber 12, so as to ensure that the printer nozzle can continuously and stably take ink from the ink supply chamber 12, and avoid the phenomenon of printing disconnection.
In other words, the buffer chamber 14 buffers the ink from the ink storage chamber 11, and when the printing operation is performed, the consumed ink in the ink supply chamber 12 can be replenished through the ink storage chamber 11 or the buffer chamber 14 in time, so that the buffer chamber 14 and/or the ink supply chamber 12 are basically in a relatively saturated state, the liquid level at the ink outlet 13 of the ink cartridge 10 under high-speed reciprocating motion is prevented from shaking, the ink outlet 13 is exposed in the air or mixed with bubbles, that is, the influence of the liquid level shaking on the printing is eliminated, the continuous and stable ink taking of the nozzle of the printer is ensured, and the phenomenon of printing line breakage is avoided.
Preferably, referring to FIG. 1, the ink cartridge 10 is generally rectangular. Of course, in other embodiments, the shape of the ink cartridge 10 may be set according to actual installation requirements. The ink cartridge 10 may be injection molded so as to form an ink storage chamber 11, an ink supply chamber 12, a buffer chamber 14, and the like inside thereof.
The ink storage chamber 11 has a shape matching the shape of the entire ink cartridge 10. Under the condition that other structural conditions are met, the volume of the ink storage cavity 11 approximately occupies 2/3-7/8 of the volume of the ink box 10, so that the ink box 10 can store ink to the maximum extent, the frequency of replacing the ink box by a user is reduced, the user experience is improved, and the printing efficiency is improved.
Further, the ink supply chamber 12 is rectangular, however, in other embodiments, the shape of the ink supply chamber 12 may be set according to actual installation requirements, for example, it may be set to be oval, cylindrical, etc.
The height of the ink supply chamber 12 is at least 1.5 times its width or length.
Further, as shown in fig. 2, the communication hole 111 is located in the buffer chamber 14, and the aperture of the communication hole 111 is smaller than the inner diameter of the ink supply chamber 12, i.e., a throat is formed between the ink supply chamber 12 and the buffer chamber 14 at the communication hole 111, so that a barrier step is formed at one end of the ink supply chamber 12 having the communication hole 111.
It can be understood that the necking has the function of partially isolating the ink supply cavity 12 from the buffer cavity 14 and the ink storage cavity 11, so that the influence of liquid level shaking inside the ink storage cavity 11 or the buffer cavity 14 on the ink supply cavity 12 can be reduced, and the continuity and stability of ink taking during the operation of the printer are effectively ensured.
Further, as shown in fig. 2 and 3, a guiding unit 15 is disposed in the ink cartridge 10, and the guiding unit 15 is configured to guide the bubbles at the ink passing hole 141 to move to an end of the buffer chamber 14 away from the communication hole.
It can be understood that the guiding unit 15 guides the ink to prevent the air bubble or air entering the buffer chamber 14 from the ink through hole 141 from entering the ink supply chamber 12, relative to the movement path (flow direction) of the air bubble/air, even if the air bubble or air is far away from the communication hole 111, so as to avoid the contact of the nozzle of the printer with the air bubble or air during printing, and further ensure the continuity and stability of ink drawing of the printer.
Specifically, the guiding unit 15 includes a guiding baffle 151, the guiding baffle 151 is located in the buffer chamber 14 and formed on a bottom surface of the ink storage chamber 11 near one end of the ink supply chamber 12, the guiding baffle 151 is arranged around the circumference of the communication hole 111, and along an axial direction of the communication hole 111, a height of the guiding baffle 151 is greater than an inner diameter of the ink through hole 141, that is, one end of the guiding baffle 151 far away from the bottom surface of the ink storage chamber 11 is higher than a position of the ink through hole 141 on a sidewall of the buffer chamber 14, so that a guiding bubble/air flow channel 152 is formed between the guiding baffle 151 and an inner wall of the buffer chamber 14.
It is understood that when air bubbles or air enter the buffer chamber 14 from the ink through hole 141, the air bubbles or air will move along the channel 152; when the air bubble or air flows out of the passage 152, it automatically moves to the end away from the communication hole 111, i.e., to the top of the buffer chamber.
Preferably, a filter unit 151a is disposed on the guiding rib 151, and the filter unit 151a is used for filtering the ink flowing from the buffer chamber 14 to the ink supply chamber 12. It can be understood that the filter unit 151a can not only filter the impurities in the ink, but also block the bubbles from entering the ink supply chamber 12 or eliminate the bubbles, thereby preventing the bubbles from entering the printer head and causing the printing disconnection.
Specifically, the filtering unit 151a may be a filter screen or other components having a filtering function.
As shown in fig. 2, the ink supply chamber 12 is disposed near one end of the ink cartridge 10 connected to the ink cartridge, the ink supply chamber 12 is substantially rectangular, and the height of the ink supply chamber 12 is greater than the width and length of the ink supply chamber, respectively, so that the ink supply chamber 12 is rectangular and long in the height (vertical) direction. It is understood that the ink supply chamber 12 is provided in a long stripe shape, and even if the liquid surface in the ink supply chamber 12 is fluctuated, the influence thereof on the ink outlet 13 can be avoided as much as possible.
Preferably, the height of the ink supply chamber 12 is 1.5 or more of its width and length.
Further, an inclined surface 121 for guiding the flow of bubbles is disposed at one end of the inner wall of the ink supply chamber 12 close to the communication hole 111, that is, a step surface for blocking the step is an inclined surface, the inclined surface 121 is inclined from the ink outlet 13 to the communication hole 111, a high position of the inclined surface is disposed close to the communication hole 111, and a low position of the inclined surface is disposed close to the ink outlet 13.
It should be explained that the upper position of the inclined plane and the lower position of the inclined plane are opposite, which is compared with the ink outlet 13 as a reference, and the upper position is farthest from the ink outlet 13 along the direction of the communication axis, and vice versa.
It can be understood that, an inclined plane 121 is provided at one end of the inner wall of the ink supply chamber 12 close to the communication hole 111, and under the guidance of the surface tension of the liquid and the inclined plane 121, the bubbles in the ink supply chamber 12 move up to the communication hole 111 along the chamber wall or enter the buffer chamber 14 or the ink storage chamber 11 through the communication hole 111, so that the bubbles in the ink supply chamber 12 are far away from the printer nozzle, and the bubble overstock in the ink supply chamber 12 is avoided, and the nozzle is contacted with the bubbles when taking ink.
With continued reference to fig. 2, the buffer chamber 14 is elongated. Preferably, in the present embodiment, the buffer chamber 14 is a rectangular parallelepiped. Of course, in other embodiments, the shape of the buffer chamber 14 may be set according to actual installation requirements. The height of the buffer cavity 14 is at least 1.5 times of the width or length of the buffer cavity 14, so that the buffer cavity 14 is arranged in a long strip shape along the vertical (height of the buffer cavity).
It can be understood that the buffer chamber 14 is arranged in a long strip shape, that is, the buffer chamber 14 is deeper in the vertical direction, and even if the liquid level is severely shaken, the ink supply chamber 12 is not exposed to the air, so that the stability and continuity of ink supply during printing are further improved.
Preferably, the internal diameter of the ink through hole 141 ranges from 1mm to 5mm in the vertical (height) direction, and only one of gas or liquid is allowed to enter/exit the buffer chamber 14 at one time. It can be understood that, when the ink cartridge is filled (filling), the ink passes through the ink supply port 14, the ink supply chamber 12, the communication hole 111, the buffer chamber 14 and the ink passing hole 141 in sequence under the action of positive and negative pressure and self gravity, and finally enters the ink storage chamber 11, the ink flows through the ink supply port 12 and the buffer chamber 14 in sequence to be preferentially in a saturated state, the thin ink passing hole avoids gas-liquid exchange between the air of the ink storage chamber 11 and the ink of the buffer chamber 14, the ink of the ink supply chamber 12 and the ink of the buffer chamber 14 is always in a saturated state, and the shaking condition is avoided.
It should be explained that, setting the inner diameter range of the ink passing hole 141 at 1mm-5mm can ensure that the ink supply amount of the ink passing hole 141 can be normally matched with the consumption of ink during printing, and avoid the situation that the ink supply chamber 12 is not supplied with ink in time; secondly, under the condition that the pressure in the ink storage cavity 11 is atmospheric pressure or is at a certain pressure, the ink in the buffer storage cavity 14 can be prevented from being guided to the ink storage cavity, that is, the ink in the buffer storage cavity 14 can be ensured to be in a saturated state.
Of course, in other embodiments, a valve may be further disposed at the ink through hole 141, and the size of the ink through hole 141 in this embodiment may not be required; therefore, the function and function of the valve at this time are replaced or equivalent to the function and function of setting the inner diameter range of the ink through hole 141 to 1mm-5 mm.
As shown in fig. 2, the ink cartridge 10 further has an air-guide chamber 16 therein, one end of the ink cartridge 10, which is opened with the ink outlet 13, is also opened with an air-guide hole 17 communicated with the atmosphere, and the ink storage chamber 11 is communicated with the air-guide hole 17 through the air-guide chamber 16, so that the ink storage chamber 11 is communicated with the atmosphere.
It can be understood that, by providing the air vent 17 and the air vent chamber 16, the ink storage chamber 11 is in a state of being communicated with the atmosphere, so that the ink in the ink storage chamber 11 is continuously conveyed to the buffer chamber 14 and the ink supply chamber 12 during the printing process under the action of the air pressure difference and the printing suction force.
As shown in fig. 2, the air guide chamber 16 and the ink storage chamber 11 may be communicated through a pipeline or directly through an air vent 161 (i.e. a side wall of the ink storage chamber 11) opened on a side wall of the air guide chamber 16, and the air guide chamber 16 and the ink storage chamber 11 are communicated through the air vent 161.
Further, a backstop 171 is installed at the communication position of the air guide cavity 16 and the ink storage cavity 11, namely the air vent 161, and the backstop 171 is used for preventing the ink in the ink storage cavity 11 from flowing out through the air guide cavity 16 and preventing the air in the air guide cavity 16 from directly flowing into the ink storage cavity 11. In other words, the backstop 171 is used to prevent the gas in the air conducting cavity 16 from directly entering the ink storage cavity 11 through the communication part (the vent 161) in the forward direction and prevent the ink in the ink storage cavity 11 from entering the air conducting cavity 16 through the communication part in the reverse direction, so as to provide a certain back pressure for the ink storage cavity 11 and the ink supply cavity 12, effectively maintain the problem of the air pressure in the ink storage cavity 11, and ensure that the ink does not drip and mix when the ink is supplied by the ink cartridge structure 100.
Preferably, the check member 171 may be a check valve, a sponge, or other functional members having the above-described functions.
Preferably, in the present embodiment, the ratchets 171 are sponges.
Further, as shown in fig. 4, the air guide cavity 16 includes a communication cavity 162 and a non-return cavity 163, the communication cavity 162 is communicated with the air guide hole 17, and one end of the non-return cavity 163, which is far away from the air guide hole 17, is communicated with the communication cavity 162, so that the communication between the communication cavity 162 and the atmosphere is realized. The air vent 161 is opened on the sidewall of the ink storage chamber 11 near the bottom of the ink supply chamber, the check chamber 163 is communicated with the air vent 171, and the check member 171 is disposed at the air vent 161.
It will be appreciated that during transport, a small portion of the ink in the ink reservoir 11 flows out through the vent 161 to the non-return chamber 163, but is absorbed by the sponge. The soaked sponge will block the vent hole 161, so that the ink in the ink storage chamber 11 cannot flow out; meanwhile, the communication chamber 162 and the non-return chamber 163 are partitioned, so that the ink can be prevented from flowing into the communication chamber 162 as well. During printing, the suction force during printing causes atmospheric air to enter the ink storage chamber 11 through the sponge.
Preferably, a partition 164 is provided in the air guide chamber 16, and the partition 164 partitions the air guide chamber 16 into a communicating chamber 162 and a non-return chamber 163.
