Description

Technical Field

[0001] The utility model relates to the technical field of printing consumables, in particular to a consumable cartridge. Background Art

[0002] With the progress of science and technology, the application of printing devices is becoming more and more extensive. Among them, a consumable cartridge, such as an ink cartridge, is used to store printing ink for the printing device to consume the ink to complete the printing work.

[0003] In the ink cartridge in the related art, an air cavity communicating with the printer is formed between the deformation film and the face cover of the cartridge body. However, this structure has high process requirements and requires the connection between the deformation film and the face cover to be completely sealed. When the welding between the deformation film and the face cover is not tight, air leakage will occur in the air cavity, affecting the use of the ink cartridge. In addition, when the air pressure in the air cavity of the ink cartridge decreases to a certain extent, it may cause the elastic member in the liquid cavity to balance with the air pressure in the air cavity, resulting in the ink cartridge stopping ink output and affecting the stable use of the ink cartridge.

[0004] Therefore, it is urgent to solve the technical problems of high process requirements for the consumable cartridge and the easy occurrence of abnormal ink flow. Summary of the Invention

[0005] The utility model provides a consumable cartridge to solve the technical problems of high process requirements for the consumable cartridge and the easy occurrence of abnormal ink flow.

[0006] To achieve the above object, the utility model provides a consumable cartridge, including:

[0007] A cartridge body, the cartridge body includes a shell main body and a cover plate arranged on the shell main body, and the outer wall of the shell main body is provided with an air filling port and an ink outlet;

[0008] An internal component, the internal component is arranged between the shell main body and the cover plate, a liquid cavity is formed between the internal component and the shell main body, the liquid cavity is communicated with the ink outlet, a gas cavity is arranged inside the internal component, the gas cavity is communicated with the air filling port, and the internal component includes a deformation film, and the deformation film and the cover plate are in a non-sealed state.

[0009] An ink cartridge provided by the present utility model realizes ink output by arranging an internal component with a gas chamber inside. The gas chamber is communicated with an inflation port. By inflating the gas chamber through the inflation port, the volume of the gas chamber expands, causing the internal component to squeeze the liquid in the liquid chamber, thereby squeezing out the liquid in the liquid chamber. When the gas chamber expands, it will squeeze the elastic member, causing the elastic member to be compressed. When the elastic force of the elastic member increases to a certain extent, the elastic member squeezes the internal component, causing the volume of the gas chamber to shrink. At the same time, since the internal component and the cover plate are in a non-sealed state, the internal component can deform according to the air pressure inside and outside the cartridge to balance the air pressure inside the cartridge. This process cycles in turn until the ink is exhausted.

[0010] In a possible implementation manner, the internal component includes a gas bag, the deformation film is a first deformation film, the first deformation film deforms according to the air pressure inside and outside the cartridge, the gas bag is located in the liquid chamber, and the inside of the gas bag is configured as the gas chamber.

[0011] In a possible implementation manner, the housing body has an open end, the first deformation film is sealed at the edge of the open end of the housing body, and the cover plate covers one side of the first deformation film relative to the housing body.

[0012] In a possible implementation manner, the internal component includes an auxiliary film, the deformation film is a second deformation film, the second deformation film deforms according to the air pressure inside and outside the cartridge, the auxiliary film is connected to the second deformation film, and the gas chamber is formed between the second deformation film and the auxiliary film.

[0013] In a possible implementation manner, the auxiliary film includes a recessed portion and a sealing portion connected to the edge of the recessed portion. The sealing portion is connected to the surface of the second deformation film facing the liquid chamber, and the recessed portion recesses away from the second deformation film.

[0014] In a possible implementation manner, the housing body has an open end, the second deformation film and the sealing portion are stacked at the edge of the open end of the housing body, and the cover plate is arranged at the open end and covers one side of the second deformation film relative to the housing body.

[0015] In a possible implementation manner, the ink cartridge further includes an elastic member. The elastic member is arranged in the liquid chamber. The housing body has a first inner wall surface facing the cover plate, and the elastic member is fixed on the first inner wall surface.

[0016] In a possible implementation manner, a positioning portion is provided on the first inner wall surface. The elastic member includes a deformation portion and a support portion. The deformation portion is disposed on the first inner wall surface and abuts against the positioning portion. The support portion is connected to the central position of the deformation portion. There is a deformation space between the support portion and the first inner wall surface, and the support portion abuts against the built-in component.

[0017] In a possible implementation manner, both the inflation port and the ink outlet are provided on the same side wall surface of the housing body.

[0018] In a possible implementation manner, a flow-through hole is formed in the first inner wall surface, and a sealing film covering the flow-through hole is provided on the outer wall of the housing body. The liquid chamber and the ink outlet are communicated through the flow-through hole.

[0019] For the consumable cartridge provided by the present utility model, since the built-in component is separately provided, the production process can be simplified, the airtightness of the gas chamber can be ensured, thereby ensuring the stability of ink output.

[0064] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0065] A consumable cartridge, such as an ink cartridge, is detachably disposed in a printing device, and the consumable cartridge supplies ink for the printing operation of the printing device.

[0066] The printing device at least includes a print head, a gas supply mechanism, a controller, a driver, and an ink supply mechanism. After the ink cartridge is installed in the printing device, the ink supply mechanism can suck out the ink stored in the ink cartridge and transfer the ink to the print head. The print head sprays the ink on a printing medium, such as paper, to generate a printed image or text. The gas supply mechanism can supply gas, such as air, into the ink cartridge. When the gas enters the ink cartridge, the pressure inside the ink cartridge increases. Under the action of the air pressure inside the ink cartridge, the ink is extruded. The driver can control the displacement of the print head and / or the platform for storing the printing medium. The controller can be used to control the working state of any of the aforementioned units.

[0067] In the related art, the cartridge body of the ink cartridge includes a shell main body and a cover plate. A deformation film is provided between the shell main body and the cover plate. The deformation film and the cover plate are sealed, which increases the difficulty of setting the deformation film. It is difficult to ensure the sealing performance between the deformation film and the cover plate, and air leakage is likely to occur. In addition, since the deformation film cannot be infinitely extended and deformed, the deformation film cannot cover all the space inside the shell main body, and a part of the space inside the shell main body cannot be squeezed, resulting in a relatively large amount of ink residue and affecting the use effect.

[0068] For better description of the consumable cartridge assembly, refer to Figure 1 As shown, a coordinate system is established: the length direction of the consumable cartridge is the X-axis direction, the thickness direction of the consumable cartridge is the Y-axis direction, and the height direction of the consumable cartridge is the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0069] In the related art, the gas channel of the ink cartridge is provided at the bottom of the ink cartridge, that is, the lower end face along the -Z direction. In this case, since the gas channel is small, it is easy to cause the gas channel to be blocked when foreign objects are accidentally brought in. In addition, labels need to be added to cover the channel to avoid affecting the product appearance, and an additional air control valve needs to be set, resulting in a complex structure. Moreover, with such a structure, air is likely to enter the ink storage cavity, easily causing the ink to oxidize and affecting the printing effect.

[0070] In view of this, a consumable cartridge provided by the present utility model includes a built-in component. The built-in component has a gas cavity inside, and the gas cavity is communicated with an inflation port. By inflating the gas cavity through the inflation port, the volume of the gas cavity expands, so that the built-in component squeezes the liquid in the liquid cavity, thereby extruding the liquid in the liquid cavity to achieve ink output. Since the built-in component includes a deformation film, the deformation film and the cover plate are in a non-sealed state, and the deformation film can deform according to the air pressure inside and outside the cartridge body to balance the air pressure inside the cartridge body, which helps to deplete the ink and reduce the ink residue.

[0071] In addition, a consumable cartridge provided by the present utility model has an air inlet and an ink outlet both disposed on the front end face of the housing body along the X-axis direction. The size of the gas passage can be increased, and the gas passage is not easily blocked, eliminating the need to provide an air control valve, resulting in a simple structure.

[0072] Embodiment 1

[0073] Reference Figure 1 、 Figure 2 and Figure 3 As shown in

[0074] The consumable cartridge provided by the present utility model includes a housing body 10 and an internal component 20. The housing body 10 includes a shell main body 11 and a cover plate 12 disposed on the shell main body 11. The outer wall of the shell main body 11 has an air inlet 13 and an ink outlet 14. The internal component 20 is disposed between the shell main body 11 and the cover plate 12. A liquid chamber 15 is formed between the internal component 20 and the shell main body 11. The liquid chamber 15 communicates with the ink outlet 14. The internal component 20 has a gas chamber 25 inside, and the gas chamber 25 communicates with the air inlet 13. The internal component 20 includes a deformable membrane, and there is a non-sealed state between the deformable membrane and the cover plate 12.

[0075] The consumable cartridge further includes an elastic member 30 disposed in the liquid chamber 15. When the gas chamber 25 expands, it will squeeze the elastic member 30, causing the elastic member 30 to be compressed. When the elastic force of the elastic member 30 increases to a certain extent, the elastic member 30 will squeeze the internal component 20, causing the volume of the gas chamber 25 to shrink. There is a non-sealed state between the deformable membrane and the cover plate 12. The deformable membrane can deform according to the air pressure inside and outside the housing body 10 to balance the air pressure inside the housing body 10. This process cycles in sequence until the ink is exhausted.

[0076] In the consumable cartridge provided by the present utility model, since the internal component 20 is separately provided, the production process can be simplified, the sealing performance of the gas chamber 25 can be ensured, thereby ensuring the stability of ink output. There is no need for a seal between the deformable membrane and the cover plate 12, which can reduce the production process requirements and improve the stability of the consumable cartridge during use.

[0077] The liquid chamber 15 is used to store liquid, namely ink. After the consumable cartridge is installed in the printing device, the ink supply mechanism can be inserted into the ink outlet 14, and the air supply mechanism is connected to the air inlet 13.

[0078] The consumable cartridge provided by the present utility model includes a housing body 10, and the housing body 10 can be generally cube-shaped.

[0079] In a possible implementation manner, the built-in component 20 includes a gas bag 22, the deformation film is the first deformation film 21, and the first deformation film 21 deforms according to the air pressure inside and outside the box body 10. The gas bag 22 is located in the liquid chamber 15, and the inside of the gas bag 22 is configured as a gas chamber 25. In this example, by providing the gas bag 22 and configuring the inside of the gas bag 22 as the gas chamber 25, the gas bag 22 can be produced separately, which can improve the sealing performance and simplify the production process, making it less likely that the outer wall of the gas chamber 25 is damaged and affects the sealing performance.

[0080] In a possible implementation manner, the first deformation film 21 can be closely attached to the cover plate 12.

[0081] In another possible implementation manner, the first deformation film 21 is not in contact with the cover plate 12, and a first chamber can be formed between the first deformation film 21 and the cover plate 12. Since the first deformation film 21 and the cover plate 12 are in a non-sealed state, the air pressure between the first deformation film 21 and the cover plate 12 is consistent with the external atmospheric pressure. The first deformation film 21 deforms according to the air pressure inside and outside the box body 10, that is, the first deformation film 21 deforms according to the external atmospheric pressure of the box body 10 and the pressure in the liquid chamber 15.

[0082] In a possible implementation manner, referring to Figure 3 and Figure 4 as shown, the first deformation film 21 and the cover plate 12 are in a non-sealed state, and air leakage holes can be provided at least on one side edge of the first chamber, so that the air outside the box body 10 can enter the first chamber through the air leakage holes, making the air pressure in the first chamber consistent with the atmospheric pressure.

[0083] In a possible implementation manner, referring to Figure 2 and Figure 3 as shown, the gas bag 22 includes a first film layer 221 and a second film layer 222. The edges of the first film layer 221 and the second film layer 222 are connected, and the gas chamber 25 is located between the first film layer 221 and the second film layer 222. The gas bag 22 has an air inlet communicating with the inflation port 13, and the air inlet can be oriented towards the inflation port 13, facilitating the air supply mechanism to inflate the gas chamber 25 through the inflation port 13, causing the gas bag 22 to expand.

[0084] In a possible implementation manner, the first film layer 221 and the second film layer 222 are elastic film layers.

[0085] In a possible implementation manner, referring to Figure 4 and Figure 5 as shown, the shell main body 11 has an open end, the first deformation film 21 is sealed at the edge of the open end of the shell main body 11, and the cover plate 12 covers the side of the first deformation film 21 relative to the shell main body 11.

[0086] The first deformable film 21 is sealed at the edge of the open end of the housing body 11, so that the air entering the first cavity cannot enter the liquid cavity 15, preventing the problem of ink leakage.

[0087] In a possible implementation manner, the first deformable film 21 can be welded to the edge of the open end of the housing body 11. The cover plate 12 serves to protect the first deformable film 21 and can prevent the problem that the first deformable film 21 is punctured.

[0088] The cover plate 12 can be connected to the open end of the housing body 11 by means such as welding, pasting, plug-in fit, and screw connection.

[0089] In a possible implementation manner, refer to Figure 3 、 Figure 6 and Figure 7 As shown, the housing body 11 has a first inner wall surface 111 facing the cover plate 12, and the elastic member 30 is fixed on the first inner wall surface 111. Such a structure is to prevent the elastic member 30 from moving around in the liquid cavity 15 and to prevent the elastic member 30 from squeezing the first deformable film 21, resulting in the first deformable film 21 losing its function of balancing air pressure.

[0090] In a possible implementation manner, the first inner wall surface 111 is provided with a positioning portion 112. The elastic member 30 includes a deformation portion 31 and a support portion 32. The deformation portion 31 is disposed on the first inner wall surface 111 and abuts against the positioning portion 112. The support portion 32 is connected to the central position of the deformation portion 31. There is a deformation space between the support portion 32 and the first inner wall surface 111, and the support portion 32 abuts against the built-in component 20. The positioning portion 112 provides positioning for the fixing and installation of the elastic member 30 and can prevent the elastic member 30 from shifting during deformation, ensuring the stability of the use of the elastic member 30.

[0091] In a possible implementation manner, the elastic member 30 can be an elastic film or a spring.

[0092] In a possible implementation manner, the support portion 32 can be plate-shaped. The deformation portion 31 applies a force to the support portion 32 to push the support portion 32 toward the built-in component 20, so as to form a negative pressure in the liquid cavity 15.

[0093] In a possible implementation manner, the materials of the deformation portion 31 and the support portion 32 can be metal, such as copper.

[0094] In a possible implementation, the deformation part 31 includes a first connecting part 311, a first connecting part 312, and an arc part 313. The arc part 313 is connected between the first connecting part 311 and the first connecting part 312. Among them, the first connecting part 311 and the first connecting part 312 are respectively connected to the first inner wall surface 111 of the liquid cavity 15. The arc part 313 is arched, and the arc part 313 protrudes towards the support part 32 and is connected to the support part 32.

[0095] The positioning part 112 can be an ear hanging protruding from the first inner wall surface 111 of the liquid cavity 15. The first connecting part 311 and the first connecting part 312 are respectively hung on the corresponding ears, so as to prevent the first connecting part 311 and the first connecting part 312 from moving closer to each other.

[0096] In a possible implementation, the number of the positioning parts 112 can be 2, 4, etc.

[0097] In the natural state, the maximum distance between the arc part 313 and the first inner wall surface 111 of the liquid cavity 15 is less than the distance between the first deformation film 21 and the first inner wall surface 111 of the liquid cavity 15.

[0098] In this embodiment, along the thickness direction of the consumable cartridge, that is, the Y-axis direction, the gas cavity 25 is located in the middle position between the first deformation film 21 and the liquid cavity 15. The elastic part 30 does not contact the first deformation film 21. The elastic part 30 mainly presses the gas cavity 25, and the elastic part 30 does not press the first deformation film 21, ensuring that the first deformation film 21 can deform according to the air pressure inside and outside the cartridge body 10, and avoiding the elastic deformation of the elastic part 30 from affecting the normal operation of the first deformation film 21.

[0099] When the air supply mechanism inflates the inflation port 13, the gas cavity 25 expands. Under the action of air pressure, the gas bag 22 drives the support part 32 to move towards the first inner wall surface 111 of the liquid cavity 15, thereby compressing the arc part 313; when the air supply mechanism stops inflating the inflation port 13, the arc part 313 can release greater elastic potential energy, which is beneficial to the gas in the gas cavity 25 to be discharged from the inflation port 13, and is beneficial to maintaining a certain negative pressure in the liquid cavity 15.

[0100] In a possible implementation, the support part 32 can be connected to the arc part 313 by welding, adhesion, integral molding, screw fitting, plug-in fitting, etc., which is not limited herein.

[0101] In a possible implementation, the inside of the arc part 313 can be provided with a hollow hole 314, which helps to increase the elasticity of the elastic part 30.

[0102] In a possible implementation, refer to Figure 1 and Figure 8As shown, the inflation port 13 and the ink outlet 14 are both provided on the same side wall surface of the housing main body 11. Among them, the inflation port 13 and the ink outlet 14 can be provided on any side wall surface of the housing main body 11. In this example, the inflation port 13 and the ink outlet 14 are both provided on the front end surface of the housing main body 11 along the X-axis direction, and the inflation port 13 and the ink outlet 14 are arranged at intervals from each other.

[0103] In other possible implementation manners, the inflation port 13 and the ink outlet 14 can also be provided on different side wall surfaces of the housing main body 11.

[0104] In one possible implementation manner, a flow-through hole 113 is formed on the first inner wall surface 111, and a sealing film 16 covering the flow-through hole 113 is provided on the outer wall of the housing main body 11. The liquid chamber 15 and the ink outlet 14 are communicated through the flow-through hole 113.

[0105] The sealing film 16 can be welded to the outer wall of the housing main body 11. The sealing film 16 blocks the outside of the flow-through hole 113 to prevent the ink stored in the liquid chamber 15 from leaking out through the flow-through hole 113.

[0106] Reference Figure 7 As shown, a consumable cartridge provided by the present utility model further includes: a chip 40. The chip 40 is provided on the outer wall surface of the cartridge body 10. The chip 40 is used to store information such as the production factory information of the consumable cartridge, the ink volume information, the consumable cartridge type information, the ink color, etc., as well as relevant processing programs and communication programs. The printing device has a contact pin electrically connected to the terminal on the chip to read the information stored in the chip 40.

[0107] Reference Figure 2 And Figure 3 As shown, after the consumable cartridge is loaded into the printing device and enters the printing state, the ink supply mechanism of the printing device extracts ink from the ink outlet 14. The ink in the liquid chamber 15 is continuously consumed, and a negative pressure gradually forms in the liquid chamber 15. To prevent the negative pressure in the liquid chamber 15 from being too large and causing the ink supply mechanism of the printing device to be unable to smoothly suck ink from the ink outlet 14, the air supply mechanism of the printing device inflates the gas chamber 25 through the inflation port 13. As the inflation volume accumulates, the volume of the gas chamber 25 continuously increases, causing the gas bag 22 forming the gas chamber 25 to deform to squeeze the ink stored in the liquid chamber 15, and squeezing out the ink stored in the liquid chamber 15.

[0108] At this time, the volume of the gas chamber 25 continuously increases, causing the elastic member 30 to be compressed. As the compression amount of the elastic member 30 increases, when the elastic force of the elastic member 30 increases to a certain extent, the supporting portion 32 of the elastic member 30 squeezes the gas bag 22, and then the air supply mechanism stops inflating. The gas in the gas chamber 25 will flow out from the inflation port 13, causing the volume of the gas chamber 25 to shrink. At the same time, since the cover plate 12 and the housing main body 11 are not completely sealed, the second deformation film 23 can deform according to the air pressure changes inside and outside the cartridge 10, and the second deformation film 23 bends to balance the air pressure inside the cartridge 10. This process cycles in sequence until the ink stored in the liquid chamber 15 is exhausted.

[0109] Considering that if the first chamber formed between the cover plate 12 and the first deformation film 21 is a completely sealed cavity, the first deformation film 21 cannot rely on the pressure inside the cartridge 10 to balance the air pressure inside the cartridge 10. Only relying on the gas chamber 25 to balance the air pressure inside the cartridge 10, the deformation amount of the gas bag 22 is limited and cannot deform to fill the entire liquid chamber 15, which will cause some ink not to be extruded, resulting in a decrease in the ink output rate and waste. Therefore, in this application, by making the built-in component 20 and the cover plate 12 in a non-sealed state, the first deformation film 21 can be used to balance the air pressure inside the cartridge 10, which helps to increase the deformation amount of the gas bag 22, improve the ink output rate, and reduce the residual amount of ink in the liquid chamber 15.

[0110] In the consumable cartridge provided by this application, the liquid chamber 15 is not connected to the outside air. During the use of the consumable cartridge, the ink will not be oxidized by the outside air and form lumps, thus avoiding the problem of blockage of the print head of the printing device.

[0111] Embodiment 2

[0112] The difference between this Embodiment 2 and Embodiment 1 is as follows: referring to Figure 9 、 Figure 10 and Figure 11 as shown, the built-in component 20 includes an auxiliary film 24, the deformation film is the second deformation film 23, the second deformation film 23 deforms according to the air pressure inside and outside the cartridge 10, the auxiliary film 24 is connected to the second deformation film 23, and a gas chamber 25 is formed between the second deformation film 23 and the auxiliary film 24.

[0113] In the consumable cartridge provided by this embodiment, the gas chamber 25 is surrounded by the second deformation film 23 and the auxiliary film 24, and there is no need to set up the gas bag 22, which can save materials.

[0114] A consumable cartridge provided in this embodiment forms a liquid chamber 15 between a housing main body 11 and an auxiliary film 24. The gas chamber 25 is no longer located within the liquid chamber 15. The gas chamber 25 and the liquid chamber 15 are separately arranged in the thickness direction of the consumable cartridge, that is, the gas chamber 25 and the liquid chamber 15 are separately arranged in the Y-axis direction. Among them, the liquid chamber 15 is close to the -Y side, and the gas chamber 25 is close to the +Y side.

[0115] Since the second deformation film 23 and the cover plate 12 are in a non-sealed state, the air pressure between the second deformation film 23 and the cover plate 12 is consistent with the atmospheric pressure. The second deformation film 23 deforms according to the air pressure inside and outside the cartridge body 10, that is, the second deformation film 23 deforms according to the pressure in the first chamber and the liquid chamber 15.

[0116] In a possible implementation manner, the auxiliary film 24 includes a recessed portion 241 and a sealing edge portion 242 connected to the edge of the recessed portion 241. The sealing edge portion 242 is connected to the surface of the second deformation film 23 facing the liquid chamber 15, and the recessed portion 241 recesses away from the second deformation film 23.

[0117] Setting the recessed portion 241 helps to increase the volume of the gas chamber 25. By injecting air into the gas chamber 25, the volume of the gas chamber 25 is increased, thereby squeezing out the ink stored in the liquid chamber 15 to achieve the ink output effect.

[0118] In a possible implementation manner, one end of the auxiliary film 24 close to the air inlet 13 has a gas channel formed by downward recessing. The corresponding position of the second deformation film 23 to the gas channel has an extension piece extending forward, which facilitates the air filled by the air supply mechanism of the printing device through the air inlet 13 to better enter the gas chamber 25 through this gas channel.

[0119] In a possible implementation manner, the housing main body 11 has an open end. The second deformation film 23 and the sealing edge portion 242 are stacked on the edge of the open end of the housing main body 11. The cover plate 12 is arranged at the open end and covers the side of the second deformation film 23 relative to the housing main body 11.

[0120] In a possible implementation manner, the second deformation film 23 and the sealing edge portion 242 can be welded to the edge of the open end of the housing main body 11. Both the second deformation film 23 and the sealing edge portion 242 are sealed with the open end of the housing main body 11, so that the outside air cannot enter the liquid chamber 15 through the open end of the housing main body 11, and the problem of ink leakage can also be prevented.

[0121] In a possible implementation manner, the second deformation film 23 can be welded to the edge of the open end of the housing main body 11. The cover plate 12 plays a role in protecting the second deformation film 23 and can prevent the problem that the second deformation film 23 is punctured.

[0122] ReferenceFigure 12 As shown, the inflation port 13 and the ink outlet 14 are both provided on the same side wall surface of the housing main body 11. In this example, the inflation port 13 and the ink outlet 14 are both provided on the front end surface of the housing main body 11 along the X-axis direction, and the inflation port 13 and the ink outlet 14 are arranged at intervals from each other.

[0123] After the consumable cartridge is loaded into the printing device and enters the printing state, the ink supply mechanism of the printing device extracts ink from the ink outlet 14, and the ink in the liquid chamber 15 is continuously consumed, and a negative pressure gradually forms in the liquid chamber 15. To prevent the negative pressure in the liquid chamber 15 from being too large and causing the ink supply mechanism of the printing device to be unable to smoothly suck ink from the ink outlet 14, the air supply mechanism of the printing device inflates the gas chamber 25 through the inflation port 13. As the inflation volume accumulates, the volume of the gas chamber 25 continuously increases, causing the auxiliary film 24 forming the gas chamber 25 to deform to squeeze the ink stored in the liquid chamber 15, and extruding the ink stored in the liquid chamber 15.

[0124] At this time, the continuous increase in the volume of the gas chamber 25 will cause the elastic member 30 to be compressed. When the elastic force of the elastic member 30 increases to a certain extent, the supporting portion 32 of the elastic member 30 squeezes the auxiliary film 24, causing the volume of the gas chamber 25 to shrink, and the gas in the gas chamber 25 is discharged from the inflation port 13. At the same time, since the cover plate 12 and the housing main body 11 are not completely sealed, the second deformation film 23 can deform according to the air pressure change inside and outside the cartridge body 10, and the second deformation film 23 bends to balance the air pressure inside the cartridge body 10. This process cycles in sequence until the ink stored in the liquid chamber 15 is exhausted.
