Description

Technical Field

[0001] This utility model belongs to the technical field of washing machine accessories, specifically relating to an ink cartridge device with a breathable function. Background Technology

[0002] Laundry detergent dispensers typically include an automatic dispensing device, which comprises a dispenser box. The dispenser box often contains several detachable cartridge units connected to a pump. When the pump operates, it draws detergent from the cartridge units onto the water circuit board. Existing patent CN216338554U discloses an identifiable automatic dispensing device, including a water tank containing a dispenser box movably connected to it. The dispenser box contains at least two detergent cartridges that engage with it. Each detergent cartridge includes a cartridge cover for mounting a sensor module. The existing automatic dispensing device has a relatively complex detergent cartridge structure. The open end of the detergent cartridge has a cartridge cover, and the top of the cartridge has a separate vent valve for ventilation. The existing structure's vent valve and cartridge cover are separate, resulting in higher manufacturing costs and more cumbersome assembly. Furthermore, the sealing requirements between the vent valve and the detergent cartridge are higher, increasing the risk of detergent leakage. Therefore, a cartridge unit with venting functionality is needed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an ink cartridge device with a breathable function. This invention sets up an air intake channel in the liquid extraction adapter assembly of the ink cartridge body, and with the help of a sealing structure, it can automatically control the opening and closing state of the air intake channel. The structure is simple and reliable and has a good liquid extraction effect.

[0004] The purpose of this invention is achieved through the following technical solution: an ink cartridge device with a breathable function, including an ink cartridge body, an ink extraction adapter assembly at the open end of the ink cartridge body, an air inlet channel and an ink extraction channel inside the ink extraction adapter assembly, a sealing structure that can deform with pressure between the air inlet channel and the chamber of the ink cartridge body; and a one-way valve inside the ink extraction adapter assembly.

[0005] Preferably, the liquid extraction adapter assembly includes a sealing cap body and an adapter body, with a one-way valve between the sealing cap body and the adapter body, and a first sealing ring installed on the one-way valve; the adapter body has a liquid extraction port, and the sealing cap body has a liquid extraction channel communicating with the liquid extraction port, with a liquid extraction plug detachably connected to the liquid extraction channel; the air inlet channel has an air inlet hole.

[0006] Preferably, the sealing cap body and the adapter body are welded together; the sealing cap body and the adapter body are welded to form an annular square groove, and a first irregularly shaped sealing element is provided in the annular square groove; the outer contour of the first irregularly shaped sealing element is adapted to the outer contour of the annular square groove, and the first irregularly shaped sealing element is disposed between the inner wall of the sealing cap body and the ink cartridge body; a first spring for resetting is provided between the one-way valve and the inner wall of the adapter body, one end of the first spring is sleeved on the one-way valve, and the other end of the first spring is disposed in the groove of the adapter body; in the default state, the one-way valve is located close to the sealing cap body, and the first sealing ring on the one-way valve abuts against the inner wall of the liquid extraction channel.

[0007] Preferably, the liquid extraction plug is provided with a plurality of second irregular-shaped sealing elements, and when the liquid extraction plug is installed on the sealing cover body, the second irregular-shaped sealing elements are disposed between the liquid extraction plug and the inner wall of the liquid extraction channel.

[0008] Preferably, the end of the sealing cap body is welded to the inner wall of the adapter body, and the outer wall of the sealing cap body is welded to the inner wall of the adapter body; a second sealing ring for sealing the two is also provided between the sealing cap body and the adapter body.

[0009] The sealing cap and adapter body are welded together, resulting in a better seal. After welding, the liquid extraction port on the adapter body and the liquid extraction channel on the cartridge body have a better seal, preventing the end of the air intake channel from communicating with the liquid extraction channel. During liquid extraction, gas can only enter the cartridge body through the air intake channel, improving air leakage prevention and increasing extraction accuracy. Simultaneously, the outer wall of the sealing cap body and the inner wall of the adapter body have a better seal, preventing detergent from leaking out of the liquid extraction adapter assembly under external pressure. A second sealing ring is also provided between the sealing cap body and the adapter body to further enhance the seal, ensuring that the air intake channel and the liquid extraction channel are independently isolated. By default, the one-way valve is closed, and the first sealing ring on the one-way valve blocks the liquid extraction channel. When the cartridge body and dispenser box are installed in the water tank inside the washing machine, the liquid extraction plug inside the washing machine inserts into the sealing cover of the cartridge body. The dispenser box and water tank are common components in existing washing machines and are not shown in the accompanying diagram. When the liquid extraction plug is inserted into the sealing cover, it pushes the one-way valve, causing it to move relative to the liquid extraction channel, thus opening the channel and allowing the piston pump inside the washing machine to extract detergent normally. By using a first and second irregularly shaped seal, the cartridge body achieves better sealing, preventing detergent spillage.

[0010] Preferably, an air intake channel extending into the ink cartridge body is provided between the sealing cover body and the adapter body, and an air intake hole is provided in the air intake channel; an annular groove is provided on the outer wall of the adapter body, and a sealing structure is provided in the annular groove, the sealing structure being a third sealing ring; the outer contour of the third sealing ring is adapted to the outer contour of the annular groove, and a plurality of evenly distributed first vent holes are provided in the annular groove, the first vent holes connecting the air intake channel and the cavity of the ink cartridge body.

[0011] When the ink cartridge is not in the liquid extraction state, the internal pressure of the ink cartridge is the same as the external pressure. At this time, the third sealing ring is installed in the annular groove, which blocks the first vent hole, and the one-way valve is also closed, preventing detergent from overflowing. When liquid extraction is performed, a certain vacuum is formed in the chamber of the ink cartridge, and the external pressure of the ink cartridge is greater than the internal pressure. In this way, air diffuses from the air inlet to the first vent hole along the air intake channel, and the air compresses the third sealing ring on the outer layer of the first vent hole. Then the first vent hole is opened, and air continuously enters the ink cartridge. Since the ink cartridge is pumped with detergent by a piston pump like a washing machine, the ink cartridge balances the pressure through the air intake channel and the first vent hole, so the ink cartridge will not be deformed by air compression, resulting in higher extraction accuracy.

[0012] Preferably, an air intake channel extending into the ink cartridge body is provided between the sealing cap body and the adapter body, and an air intake hole is provided in the air intake channel; a sealing structure is provided at the end of the air intake channel facing the ink cartridge body, and the sealing structure is an umbrella-shaped sealing diaphragm; a second vent is provided on the adapter body to connect the ink cartridge body and the air intake channel; the umbrella-shaped sealing diaphragm includes a sealing diaphragm body, and an annular sealing part is integrally formed thereon on the sealing diaphragm body; the sealing diaphragm body is disposed between the sealing cap body and the adapter body, and in the default state, the annular sealing part abuts against the end of the air intake channel.

[0013] The sealing diaphragm is positioned between the sealing cap and the adapter body, ensuring a better seal between them. When the cartridge is not in the liquid extraction state, the internal pressure is the same as the external pressure. At this time, the annular seal rests against the air intake channel, which is closed, and the one-way valve is also closed, preventing detergent leakage. During liquid extraction, a vacuum is created within the cartridge chamber, and the external pressure is greater than the internal pressure. This causes air to compress the annular seal, moving it away from the end of the air intake channel. Air then diffuses along the air intake channel from the air inlet to the second vent, which is connected to the air intake channel, allowing continuous airflow into the cartridge. Since the cartridge uses a piston pump similar to those in washing machines to extract detergent, the pressure is balanced by the air intake channel and the second vent, preventing deformation from air compression and improving extraction accuracy. The umbrella-shaped sealing diaphragm further enhances the sealing effect of the liquid extraction adapter assembly. When the ink cartridge body is subjected to external pressure, the detergent inside the ink cartridge body will squeeze the umbrella-shaped sealing diaphragm, thus blocking the air intake channel and preventing detergent from overflowing.

[0014] Preferably, an air intake channel extending into the ink cartridge body is provided between the sealing cover body and the adapter body, and an air intake hole is provided in the air intake channel; a sealing structure, namely a fourth sealing ring, is provided at the end of the air intake hole facing the ink cartridge body; a third vent hole is provided on the adapter body to connect the ink cartridge body and the air intake channel, and the fourth sealing ring is disposed between the adapter body and the sealing cover body; an annular groove is provided at the end of the sealing cover body facing away from the air intake hole, and the fourth sealing ring is disposed in the annular groove; the outer contour of the fourth sealing ring is adapted to the outer contour of the annular groove, and the air intake hole is disposed through the annular groove; a semi-annular limiting rib is provided at the end of the adapter body facing the sealing cover body, and the semi-annular limiting rib abuts against the fourth sealing ring.

[0015] When the ink cartridge is not in the liquid extraction state, the internal pressure of the ink cartridge is the same as the external pressure. At this time, the fourth sealing ring abuts against the air inlet, the air intake channel is closed, and the one-way valve is also closed, preventing detergent from overflowing. When liquid extraction is performed, a certain vacuum is formed in the chamber of the ink cartridge, and the external pressure of the ink cartridge is greater than the internal pressure. Air then diffuses along the air intake channel from the air inlet to the third vent, which is connected to the air intake channel, allowing air to continuously enter the ink cartridge. Here, the fourth sealing ring is partially compressed by a semi-circular limiting rib, with the end of the fourth sealing ring near the air inlet not being limited. When the internal pressure of the ink cartridge is lower than the external pressure, the end of the fourth sealing ring near the third vent is pushed open by the air, thus opening the air inlet and allowing air to continuously enter the ink cartridge. Since the ink cartridge is pumped by a piston pump similar to that in a washing machine, the ink cartridge balances the pressure through the air intake channel and the third vent, preventing the ink cartridge from being deformed by air compression and resulting in higher extraction accuracy.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The sealing cover body and the adapter body of the present invention are welded together, resulting in better sealing and easier installation; 2. An air intake channel is provided in the liquid extraction adapter cover assembly. During the liquid extraction process, the pressure inside the ink cartridge body can be balanced through the air intake channel, preventing deformation of the ink cartridge body as a whole, making liquid extraction smoother and more accurate; 3. The sealing structure is made of rubber. When air compresses the sealing structure, the sealing structure can automatically control the opening and closing of the air intake channel, making the structure simple and reliable.

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Example 1 like Figures 1 to 6 As shown, this embodiment discloses an ink cartridge device with a breathable function, including an ink cartridge body 1. The open end of the ink cartridge body 1 is provided with a liquid extraction adapter cover assembly 2. The liquid extraction adapter cover assembly 2 includes a sealing cover body 201 and an adapter body 202. The sealing cover body 201 and the adapter body 202 are welded together. The liquid extraction adapter cover assembly 2 is provided with an air inlet channel 3. A sealing structure that can deform with pressure is provided between the air inlet channel 3 and the chamber of the ink cartridge body 1. The air inlet channel 3 is provided with an air inlet hole 4. The liquid extraction adapter cover assembly 2 is provided with a one-way valve 5.

[0019] The sealing cap body 201 and the adapter body 202 are welded together to form an annular square groove 7. A first irregularly shaped sealing element 8 is provided in the annular square groove 7. The outer contour of the first irregularly shaped sealing element 8 is adapted to the outer contour of the annular square groove 7. The first irregularly shaped sealing element 8 is disposed between the sealing cap body 201 and the inner wall of the ink cartridge body 1. A one-way valve 5 is provided between the sealing cap body 201 and the adapter body 202. A first sealing ring 9 is installed on the one-way valve 5. The adapter body 202 is provided with a liquid extraction port 10. The sealing cap body 201 is provided with a liquid extraction channel 11 that is connected to the liquid extraction port 10. A liquid extraction plug 6 that is detachably connected to the liquid extraction channel 11 is provided in the liquid extraction channel 11. A first spring 12 for resetting is provided between the one-way valve 5 and the inner wall of the adapter body 202. One end of the first spring 12 is sleeved on the one-way valve 5, and the other end is located in the groove of the adapter body 202. In the default state, the one-way valve 5 is located close to the sealing cap body 201, and the first sealing ring 9 on the one-way valve 5 abuts against the inner wall of the liquid extraction channel 11. The liquid extraction plug 6 is provided with several second irregularly shaped sealing elements 13. When the liquid extraction plug 6 is installed on the sealing cap body 201, the second irregularly shaped sealing elements 13 are located between the liquid extraction plug 6 and the inner wall of the liquid extraction channel 11. The end of the sealing cap body 201 is welded to the inner wall of the adapter body 202, and the outer wall of the sealing cap body 201 is welded to the inner wall of the adapter body 202. A second sealing ring 14 for sealing the sealing cap body 201 and the adapter body 202 is also provided between them. An air intake channel 3 extending into the ink cartridge body 1 is provided between the sealing cover body 201 and the adapter body 202. An air intake hole 4 is provided in the air intake channel 3. An annular groove 15 is provided on the outer wall of the adapter body 202. A sealing structure is provided in the annular groove 15. The sealing structure is a third sealing ring 16. The outer contour of the third sealing ring 16 is adapted to the outer contour of the annular groove 15. A plurality of evenly distributed first vent holes 17 are provided in the annular groove 15. The first vent holes 17 connect the air intake channel 3 and the cavity of the ink cartridge body 1.

[0020] The specific operation process of this embodiment is as follows: the sealing cap body 201 and the adapter body 202 are welded together, thus achieving better sealing. After welding, the liquid extraction port 10 on the adapter body 202 and the liquid extraction channel 11 on the cartridge body 1 have better sealing, preventing the end of the air intake channel 3 from communicating with the liquid extraction channel 11. During the liquid extraction process, gas can only enter the cartridge body 1 through the air intake channel 3, resulting in better air leakage prevention and higher liquid extraction accuracy. Simultaneously, there is better sealing between the outer wall of the sealing cap body 201 and the inner wall of the adapter body 202, preventing detergent in the cartridge body 1 from leaking out of the gaps in the liquid extraction adapter cap assembly 2 under external pressure. A second sealing ring 14 is also provided between the sealing cap body 201 and the adapter body 202 to further enhance the sealing effect, thereby ensuring that the air intake channel 3 and the liquid extraction channel 11 are independently separated. By default, the one-way valve 5 is closed, and the first sealing ring 9 on the one-way valve 5 blocks the liquid extraction channel 11. When the cartridge body 1 and the dispenser box are installed in the water tank inside the washing machine, the liquid extraction plug 6 inside the washing machine will insert into the sealing cover body 201 of the cartridge body 1. The dispenser box and the water tank are common accessories in existing washing machines and are not shown in the attached drawings of the instruction manual. When the liquid extraction plug 6 is inserted into the sealing cover body 201, it can push the one-way valve 5, so that the one-way valve 5 will move relative to the liquid extraction channel 11, thereby opening the liquid extraction channel 11. When the piston pump inside the washing machine is working, it can draw detergent normally. By setting the first irregular seal 8 and the second irregular seal 13, the cartridge body 1 can have better sealing performance and prevent detergent from overflowing.

[0021] When the ink cartridge body 1 is not in the liquid extraction state, the internal pressure of the ink cartridge body 1 is the same as the external pressure. At this time, the third sealing ring 16 is fitted into the annular groove 15, and the third sealing ring 16 will block the first vent hole 17. The one-way valve 5 is also in the closed state, and the detergent will not overflow. When liquid extraction is performed, a certain vacuum is formed in the cavity of the ink cartridge body 1, and the external pressure of the ink cartridge body 1 is greater than the internal pressure of the ink cartridge body 1. In this way, air will diffuse from the air inlet 4 to the first vent hole 17 along the air inlet channel 3. The air will squeeze the third sealing ring 16 on the outer layer of the first vent hole 17. Then the first vent hole 17 will be in the open state, and air will continuously enter the interior of the ink cartridge body 1. Since the ink cartridge body 1 extracts detergent through the piston pump on the washing machine, the ink cartridge body 1 balances the pressure through the air inlet channel 3 and the first vent hole 17. In this way, the ink cartridge body 1 will not be deformed by air compression, and the extraction accuracy is higher.

[0022] Example 2 like Figures 7 to 8As shown, the sealing structure in this embodiment differs from that in Embodiment 1, while other structures are the same as in Embodiment 1. In this embodiment, an air intake channel 3 extending into the ink cartridge body 1 is provided between the sealing cover body 201 and the adapter body 202. An air intake hole 4 is provided within the air intake channel 3. A sealing structure, specifically an umbrella-shaped sealing diaphragm 18, is provided at the end of the air intake channel 3 facing the ink cartridge body 1. The adapter body 202 has a second vent 19 that connects the ink cartridge body 1 and the air intake channel 3. The umbrella-shaped sealing diaphragm 18 includes a sealing diaphragm body 181, on which an annular sealing portion 182 is integrally formed. The sealing diaphragm body 181 is disposed between the sealing cover body 201 and the adapter body 202. In the default state, the annular sealing portion 182 abuts against the end of the air intake channel 3.

[0023] The specific operation process of this embodiment is as follows: the sealing diaphragm body 181 is set between the sealing cover body 201 and the adapter body 202, so that the sealing cover body 201 and the adapter body 202 have better sealing performance; when the ink cartridge body 1 is not in the liquid extraction state, the internal pressure of the ink cartridge body 1 is the same as the external pressure; at this time, the annular sealing part 182 abuts against the air intake channel 3, the air intake channel 3 is in the closed state, the one-way valve 5 is also in the closed state, and the detergent will not overflow; when liquid extraction is performed, a certain vacuum is formed in the chamber of the ink cartridge body 1, and the ink cartridge body... When the external pressure of the cartridge body 1 is greater than the internal pressure of the cartridge body 1, the air will compress the annular seal 182, moving it away from the end of the air intake channel 3. This allows the air to diffuse along the air intake channel 3 from the air intake hole 4 to the second vent hole 19. The second vent hole 19 is connected to the air intake channel 3, allowing air to continuously enter the cartridge body 1. Since the cartridge body 1 uses a piston pump like in a washing machine to extract detergent, the pressure of the cartridge body 1 is balanced by the air intake channel 3 and the second vent hole 19, preventing the cartridge body 1 from being deformed by air compression and improving extraction accuracy. The umbrella-shaped sealing diaphragm 18 further enhances the sealing effect of the liquid extraction adapter assembly 2. When the cartridge body 1 is subjected to external pressure, the detergent inside the cartridge body 1 will compress the umbrella-shaped sealing diaphragm 18, thus blocking the air intake channel 3 and preventing detergent leakage.

[0024] Example 3 like Figures 9 to 11As shown, the sealing structure in this embodiment differs from that in Embodiment 1, while other structures are the same as in Embodiment 1. In this embodiment, an air intake channel 3 extending into the ink cartridge body 1 is provided between the sealing cover body 201 and the adapter body 202. An air intake hole 4 is provided within the air intake channel 3. A sealing structure, namely a fourth sealing ring 20, is provided at the end of the air intake hole 4 facing the ink cartridge body 1. The sealing structure is a fourth sealing ring 20. A third vent 21, connecting the ink cartridge body 1 and the air intake channel 3, is provided on the adapter body 202. The fourth sealing ring 20... A ring 20 is disposed between the adapter body 202 and the sealing cover body 201; the end of the sealing cover body 201 facing away from the air inlet 4 is provided with an annular groove 22, and a fourth sealing ring 20 is disposed in the annular groove 22; the outer contour of the fourth sealing ring 20 is adapted to the outer contour of the annular groove 22, and the air inlet 4 is disposed through the annular groove 22; the end of the adapter body 202 facing the sealing cover body 201 is provided with a semi-annular limiting rib 23, and the semi-annular limiting rib 23 abuts against the fourth sealing ring 20.

[0025] The specific operation process of this embodiment is as follows: When the ink cartridge body 1 is not in the liquid extraction state, the internal pressure of the ink cartridge body 1 is the same as the external pressure; at this time, the fourth sealing ring 20 abuts against the air inlet 4, the air inlet channel 3 is in the closed state, the one-way valve 5 is also in the closed state, and the detergent will not overflow; when liquid extraction is performed, a certain vacuum is formed in the cavity of the ink cartridge body 1, and the external pressure of the ink cartridge body 1 is greater than the internal pressure of the ink cartridge body 1; in this way, air will diffuse from the air inlet 4 to the third vent 21 along the air inlet channel 3, and the third vent 21 is in the conductive state with the air inlet channel 3, so air will continuously enter the interior of the ink cartridge body 1; here, the fourth sealing ring 20 is partially squeezed by the semi-circular limiting rib 23, and the end of the fourth sealing ring 20 near the air inlet 4 is not limited; when the internal pressure of the ink cartridge body 1 is lower than the external pressure, the end of the fourth sealing ring 20 near the third vent 21 is pushed open by the air, so the air inlet 4 will be in the open state, and air can continuously enter the interior of the ink cartridge body 1. Since the ink cartridge body 1 is pumped with detergent by the piston pump on the washing machine, the ink cartridge body 1 balances the pressure through the air intake channel 3 and the third vent 21, so that the ink cartridge body 1 will not be squeezed and deformed by air, and the extraction accuracy is higher.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
