When a conventional ink replenishing bottle is used to fill a consumable ink cartridge with ink, an outlet valve unit is generally provided in an ink outlet portion of the ink replenishing bottle. The outlet valve unit is composed of an outlet sealing member, a movable sealing member, and a spring member attached to the tubular flow path portion. When the ink replenishing bottle is not used, the movable sealing part is jacked up to the top end by the spring part, and one end of the movable sealing part is abutted against the opening of the outlet sealing part, so that sealing is completed; when ink needs to be replenished, the movable sealing member is pushed by the ink inlet flow path member and moves toward the container body side, and at this time, the sealing state of the movable sealing member and the outlet sealing member is disengaged, however, as the number of times and time of use increase, the elasticity of the spring member of the outlet valve unit gradually decreases, and further, the opening of the ink bottle cannot be effectively closed in an unused state, and the sealing performance decreases, thereby causing ink dripping and ink leakage.

As shown in fig. 1 to 7, the present embodiment provides an ink bottle 1 for connecting with an insertion needle 3 of an ink tank 2 of a printer, the ink bottle 1 including: the container body 10, the connecting member 20, and the lid body 30; the container body 10 is a hollow structure having a first inner cavity 11, an opening 12 communicating with the first inner cavity 11 is formed at the upper end of the container body 10, the upper end of the container body 10 is connected with a connecting member 20, the connecting member 20 has a second inner cavity 21 communicating with the opening 12, and the cover 30 is connected with the connecting member 20.

Specifically, the container body 10 is a hollow shell having a first inner cavity 11 and is used for containing ink, an opening 12 is formed in the upper end of the container body 10, the opening 12 is communicated with the first inner cavity 11 so as to facilitate the outflow and inflow of the ink, one end (namely, the upper end) of the opening 12 of the container body 10 is connected with a connecting member 20, the connecting member 20 is a hollow connecting member having a second inner cavity 21, a cover body 30 is covered on the outer side of the upper portion of the connecting member 20, and the cover body 30 can be movably connected with the connecting member 20.

It should be noted that, the upper end of the container body 10 is connected to the connecting member 20, and in order to facilitate adding ink, the upper end of the container body 10 and the connecting member 20 may be movably connected, for example, the upper end of the container body 10 and the connecting member 20 are screwed together, that is, the upper end of the container body 10 and the connecting member 20 may be in threaded connection, or the upper end of the container body 10 and the connecting member 20 are in snap-fit connection, and the movable connection between the upper end of the container body 10 and the connecting member 20 may be completed, which is not limited in this embodiment.

The connecting piece 20 has a second inner cavity 21 communicated with the first inner cavity 11, an outflow port 22 is opened at an end of the second inner cavity 21, the outflow port 22 is disposed corresponding to the opening 12, and the outflow port 22 is used for inserting the insertion needle 3. When the ink bottle 1 is connected to the insertion needle 3 of the ink tank 2, the insertion needle 3 is inserted into the second chamber 21 through the outflow port 22, and the ink in the first chamber 11 flows out into the insertion needle 3 through the outflow port 22 of the second chamber 21. When the ink bottle 1 is connected to the insertion needle 3 of the ink tank 2, it is generally necessary to connect the ink bottle 1 upside down to the insertion needle 3 so that the ink flows out under the effect of gravity. In order to avoid ink from the ink bottle 1 from flowing out when the ink bottle 1 is inverted before being connected to the insertion needle 3, an outlet valve with a spring is usually provided at the outflow port. In normal state, the outlet valve is pushed up by the spring and is pressed against the opening, and the ink cannot flow out when the ink bottle is inverted. When the ink bottle is connected to the insertion needle, the insertion needle pushes up the outlet valve toward the inside of the ink bottle, so that the ink can flow out into the insertion needle from the pushed-up periphery of the outlet valve. However, as the number of times and time of use increase, the elasticity of the spring member of the outlet valve unit gradually decreases, and thus the ink bottle cannot effectively close the opening, resulting in the phenomena of ink dripping and ink leakage.

In the present embodiment, a porous member 23 is provided in the second lumen 21 at a position corresponding to the outflow port 22, the porous member 23 can block the liquid in the first lumen 11, and when the insertion needle 3 is connected to the outflow port 22, the porous member 23 is in an open state.

Specifically, the porous member 23 is provided at the outflow port 22, and the porous member 23 is penetrated by the insertion needle 3. When the porous member 23 is not connected to the insertion needle 3, the porous member 23 is in a closed state. That is, when the ink bottle 1 is horizontally placed after the cap 30 of the ink bottle 1 is removed, the porous member 23 allows the inside of the container body 10 to communicate with the outside air, so that the air pressure inside the container body 10 is maintained to be the same as the outside air pressure, and thus, when the ink bottle 1 is inverted, ink ejection due to instantaneous release of excessive air pressure inside the ink bottle 10 is not caused. Further, the porous member 23 is closed before the ink bottle 1 is connected to the insertion needle 3 after being inverted, so that the ink flowing out from the container body 10 can be blocked and the ink does not leak in a short time. After the ink is filled and the ink bottle 1 is taken out, the porous member 23 can function as a valve unit, and when the ink bottle 1 is disconnected from the insertion needle 3, the porous member 23 returns to the closed state again and blocks the ink replenishment path, preventing the ink from flowing out from the outflow port 22.

It is to be noted that, in the present embodiment, the open and closed states of the porous member 23 are achieved by insertion and extraction of the insertion needle 3, the porous member 23 is opened when the insertion needle 3 is inserted into the porous member 23, and the porous member 23 is closed after the insertion needle 3 is extracted. The porous member 23 is provided with a slit 231 into which the insertion needle 3 is inserted. It is understood that the porous member 23 may be made of a material having a certain elasticity, and in the normal state, the cut 231 is in the closed state due to the elasticity; the insertion needle 3 is inserted into the second lumen 21 from the slit 231 with the porous member 23 in the open state; after the insertion needle 3 is pulled out, the incision 231 is restored to be closed.

In addition, the porous member 23 needs to ensure communication between the inside and the outside atmosphere in a normal state, and at the same time, needs to provide a sealing effect on the ink inside in a short time when the ink bottle 1 is inverted, and the porous member 23 should be made of one or more porous materials such as sponge, filter screen, porous silica gel, gauze, and porous wooden plug. For example, when the porous member 23 is made of a sponge material, while ensuring air permeability, the porous member may provide a certain sealing effect when the ink bottle 1 is inverted, and has a certain elasticity, so as to facilitate the insertion of the insertion needle 3, which is not limited in this embodiment.

In use, the cover 30 covers the connector 20 and provides a seal. After the cover 30 is opened, the sealing state of the ink bottle 1 is released, the porous member 23 is in a closed state at this time, and the porous member 23 can allow air to enter and exit the first inner chamber 11, so that the air pressure in the first inner chamber 11 is ensured to be the same as the external atmospheric pressure, and thus when the ink bottle 1 is inverted, ink cannot be ejected due to the instant release of the overlarge air pressure in the ink bottle 10. When the ink bottle 10 is turned upside down when it is necessary to connect with the ink tank 2, the porous member 23 can block the ink flowing out from the container body 10, and does not cause ink leakage in a short time, providing a buffering time for connecting the ink bottle 1 and the ink tank 2. When the ink bottle 1 and the ink tank 2 are connected, the ink bottle 1 is connected to the insertion needle 3 through the outflow port 22. The insertion needle 3 is inserted into the second chamber 21 through the slit 231 of the porous member 23 in the outflow port 22, and the porous member 23 is in an open state, so that ink can flow out from the first chamber 11 into the ink tank 2. After the ink is filled and the ink bottle 1 is taken out, the porous member 23 can function as a valve unit, and when the ink bottle 1 is disconnected from the insertion needle 3, the porous member 23 returns to the closed state again and blocks the ink replenishment path, preventing the ink from flowing out from the outflow port 22.

The present embodiment provides an ink bottle 1 including a container body 10, a connector 20, and a lid 30, and a porous member 23 is provided at an outflow port 22 on the connector 20. The porous part 23 is in a closed state in a normal state, so that the internal and external atmospheric pressures of the ink bottle 1 are the same while the ink flow path is ensured to be blocked to a certain extent, and the ink can flow out more slowly when the ink bottle 1 is inverted; meanwhile, after the ink bottle 1 is connected with the insertion needle 3, the porous component 23 is in an open state, ink can flow out of the first inner cavity 11 into the ink tank, and after the insertion needle 3 is pulled out, the porous component 23 returns to a closed state again and cuts off an ink replenishing path. Through the setting of porous part 23, can effectual control ink's outflow state, cancelled and used the spring valve body to realize the flow path break-make of ink among the prior art, solved when the elasticity of the spring part of outlet valve unit reduces gradually, the ink bottle can not seal the opening effectively under the state of not supplying to lead to dripping the china ink, the problem of leaking the china ink.

Various possible implementations of the ink bottle 1 are described below.

When the porous member 23 is disposed within the second lumen 21, the insertion needle 3 pushes the porous member 23 to move toward the inside of the second lumen 21 during the insertion of the insertion needle 3. In order to avoid that the porous member 23 cannot move freely and ensure the stability of the insertion needle 3 when being connected with the connecting member 20, optionally, the inner wall periphery of the second inner cavity 21 is provided with a limit boss 24 extending towards the center of the second inner cavity 21, the limit boss 24 abuts against the bottom of the porous member 23, and a gap is formed between the limit boss 24 and the outer wall surface of the insertion needle 3.

Specifically, the limit projection 24 is provided on the inner wall peripheral side of the second inner cavity 21, and the limit projection 24 is used for limiting the position of the porous member 23. It will be appreciated that in order to avoid the insertion needle 3 pushing the porous member 23 to move towards the inside of the second lumen 21 during insertion, the stop boss 24 abuts against the underside of the porous member 23, and the stop boss 24 may limit the porous member 23 from moving towards the inside of the second lumen 21 during insertion of the insertion needle 3 into the porous member 23. It should be noted that the limiting boss 24 may be a single or multiple protrusions, preferably multiple protrusions, disposed on the inner wall of the second inner cavity 21; the stopper boss 24 may be an annular projection provided on the inner wall of the second inner chamber 21, and the entire bottom surface peripheral side of the stopper boss 24 may be defined by abutment. In addition, in order to facilitate the insertion needle 3 to smoothly enter the second inner cavity 21 through the porous member 23, a gap is formed between the limiting boss 24 and the outer wall surface of the insertion needle 3, and the gap can also play a role of containing ink, thereby effectively preventing the ink adsorbed on the porous member 23 from leaking out of the bottle.

During the insertion of the insertion needle 3, since the cavity of the second inner cavity 21 is larger than the diameter of the insertion needle 3 so as to facilitate the insertion of the insertion needle 3, after the insertion needle 3 is inserted into the second inner cavity 21, the needle portion of the insertion needle 3 is directly communicated with the ink in the first cavity 11. In order to provide a certain flow restriction effect for the ink and facilitate the fixation of the insertion needle 3 after being inserted into the second cavity 21, the ink container further comprises a fixing portion 25, the fixing portion 25 is disposed in the second cavity 21 and abuts against the inner wall of the second cavity 21, one end of the fixing portion 25 facing the container body 10 is engaged with the second cavity 21, and the top end of the fixing portion 25 abuts against the insertion needle 3.

The end of the fixing portion 25 facing the container body 10 (i.e. the lower end of the fixing portion 25) is engaged with the second cavity 21, and it can be understood that a bayonet for limiting the fixing portion 25 is provided at the joint of the bottom of the second cavity 21 and the fixing portion 25, so as to limit and fix the end of the fixing portion 25. For example, the diameter of the connection portion between the bottom of the second inner cavity 21 and the first inner cavity 11 is smaller than the diameter of the fixing portion 25, and the bottom end of the fixing portion 25 abuts against the connection portion and cannot move toward the first inner cavity 11, which is not limited in this embodiment. When the insertion needle 3 is inserted into the second lumen 21, one end of the insertion needle 3 abuts against the top surface of the fixing portion 25, thereby restricting and fixing the position of the insertion needle 3.

In addition, in order to secure the relative position between the ink bottle 1 and the ink tank 2 when the insertion needle 3 abuts against the fixing portion 25, the fixing portion 25 may have a protrusion 251 that is matched with the insertion needle 3 on the side facing the outlet port 22, the height of the protrusion 251 does not exceed the height of the stopper boss 24, and the protrusion 251 is used to engage with the end of the insertion needle 3.

Wherein, the effect of arch 251 is with the tip block of inserting needle 3, be provided with the dodging groove with arch 251 assorted in the ink inlet opening department of inserting needle 3 usually, and arch 251 can set up to be can with dodge the groove and block solid spline etc. each other, exemplarily, arch 251 can set up to the crisscross spline for the tip, insert when needle 3 inserts second inner chamber 21 and arch 251 offsets, the spline card is in dodging the groove, ink bottle 1 can not rotate at will this moment, can accomplish between ink bottle 1 and the ink tank 2 can not relative movement, this embodiment does not restrict this.

It should be noted that, when the end surface of the fixing portion 25 abuts against the insertion needle 3, in order to facilitate smooth introduction of the ink in the container body 10 into the insertion needle 3, a flow passage 252 communicating the first inner chamber 11 and the outflow port 22 is optionally formed in the fixing portion 25, one end of the flow passage 252 communicates with the end surface of the projection 251, and the other end of the flow passage 252 communicates with the first inner chamber 11. That is, the flow path 252 is opened inside the fixing portion 25 and communicates with both ends of the fixing portion 25, wherein one end of the flow path 252 is disposed on the end surface of the projection 251 of the fixing portion 25, that is, when the fixing portion 25 abuts against the insertion needle 3, one end of the flow path 252 communicates with the needle hole of the insertion needle 3, so that the ink can directly enter the insertion needle 3 from the flow path 252.

Further, in order to ensure the whole sealing performance of the ink bottle 1, the ink bottle further comprises a sealing assembly, the sealing assembly comprises a sealing ring 31, the sealing ring 31 is arranged on the periphery of the outflow port 22, the bottom surface of the sealing ring 31 abuts against the top surface of the porous component 23, and a through hole for the insertion needle 3 to pass through is formed in the sealing ring 31.
