Description

inkjet printing device Technical Field

[0001] This invention relates to the field of printing equipment technology, and in particular to an inkjet printing device. Background Technology

[0002] In related technologies, inkjet printing devices are mostly equipped with ink cartridge components to store ink and use the ink cartridge components to supply ink to the print head, ensuring stable inkjet printing operations on printing materials such as fabrics and films.

[0003] However, most current inkjet printers use ink cartridge assemblies located outside the casing. The ink supply lines connecting the ink cartridge assembly and the printhead need to pass through the casing, resulting in a rather scattered arrangement of the ink supply lines within the inkjet printer. This can easily lead to tangling and knotting of the lines, affecting the stable ink supply to the printing device. Summary of the Invention

[0013] In one embodiment, the inkjet printing apparatus further includes a waste ink cartridge disposed within the receiving space and adjacent to the ink stack assembly. The waste ink cartridge is located on one side of the printing stage in the direction of movement of the printing assembly. The inkjet printing apparatus further includes a drain pipe connecting the ink stack assembly and the waste ink cartridge, and connecting the ink extraction assembly to the waste ink cartridge, so as to extract waste liquid from the ink stack assembly to the waste ink cartridge.

[0014] In one embodiment, the housing has a first operating port on one side of the printing assembly in the direction of movement. The first operating port is disposed opposite to the ink stack assembly and the waste ink cartridge.

[0016] In one embodiment, the housing has a second operating port on the side adjacent to the reflective component. The inkjet printing device also includes a second door, which is movably mounted on the housing to open or close the second operating port. The inkjet printing device also includes a second opening / closing detection component, which is located on the housing and can cooperate with the second door to detect the opening / closing status of the second door.

[0017] In one embodiment, the inkjet printing device further includes a support, the printing assembly is movably disposed on the support, the ink cartridge assembly includes a support frame and an ink cartridge, the support frame is disposed within the receiving space and located on the upper side of the support, and the ink cartridge is disposed on the support frame.

[0018] In one embodiment, the support frame has a mounting groove extending in a direction parallel to the moving direction of the printing component, and there are several ink cartridges arranged sequentially in the mounting groove along a direction parallel to the moving direction.

[0019] In one embodiment, a wire-passing groove is also formed on the support frame. The wire-passing groove is located on one side of the mounting groove and communicates with the mounting groove. The wire-passing groove penetrates the side wall of the support frame, and the ink supply pipeline passes through the wire-passing groove.

[0020] In one embodiment, the top of the housing has a loading / unloading port communicating with the receiving space, the loading / unloading port being located above the ink cartridge assembly.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0043] In related technologies, inkjet printing devices include, but are not limited to, DTF printers ("Direct to Film") and DTG printers ("Direct to Garment"). Most inkjet printing devices are equipped with ink cartridge assemblies to store ink. Ink supply lines connect the ink cartridge assembly and the printhead, ensuring a stable supply of ink from the cartridge to the printhead. This guarantees the printhead continuously ejects ink onto fabrics, films, and other printing materials, accurately forming the desired image or text, thus enabling inkjet printing. However, to facilitate ink refilling and monitoring of remaining ink, most current printing devices mount the ink cartridge assembly on the outside of the casing. This separates the ink cartridge assembly from other components, affecting the overall integrity of the printing device and making factory packaging and daily storage inconvenient. Understandably, during printing, the ink cartridge assembly continuously supplies ink to the print head, allowing the print head to spray ink onto the printing material according to a pre-programmed path. Users can visually see the remaining ink level in the cartridge assembly, located on the outside of the casing, and easily refill the cartridges. However, the exposed cartridge assembly requires more space for packaging the printing device, resulting in significant excess space inside the packaging. Furthermore, the ink supply lines connecting the cartridge assembly and the print head need to run through the casing, leading to a more scattered arrangement of the ink supply lines within the inkjet printer, making them prone to tangling and knots, which can affect the stable ink supply to the printing device.

[0044] To address the aforementioned problems, this invention proposes an inkjet printing device 100. It should be noted that the inkjet printing device 100 proposed in this application can be a DTF printer, a DTG printer, a piezoelectric inkjet printer, or a thermal inkjet printer, etc., as long as it is a device used for jetting ink for printing operations. The printing material processed by the printing device in this application can be paper, film, or even fabric, etc. This application does not limit the material and shape of the printing material, as long as it is a material that can be printed in the inkjet printing device.

[0045] Please refer to Figures 1 to 9. In one embodiment of the present invention, the inkjet printing device 100 includes a housing 10, a print stage 33, a printing assembly 30, an ink cartridge assembly 50, and an ink supply line 40. A receiving space 10a is formed inside the housing 10. The print stage 33 is disposed within the receiving space 10a. The printing assembly 30 is movably disposed within the receiving space 10a and is located above the print stage 33. The ink cartridge assembly 50 is disposed within the receiving space 10a and is located behind the printing assembly 30. The ink supply line 40 is disposed within the receiving space 10a and connects the ink cartridge assembly 50 and the printing assembly 30, so that the ink cartridge assembly 50 supplies ink to the printing assembly through the ink supply line 40. At least a portion of the ink supply line 40 is located behind the printing assembly 30 and extends along the moving direction of the printing assembly 30.

[0046] In this application, the housing 10 provides a certain degree of protection. The housing 10 encloses and forms a receiving space 10a, which protects components such as the print station 33, print assembly 30, and ink cartridge assembly 50 located within it. Furthermore, a support structure can be installed within the housing 10 to support and carry each component, ensuring stable installation and stable printing operations of the inkjet printer 100. The housing 10 can be a regular-shaped box structure, such as a square or cylindrical box, or it can be an irregular-shaped box structure. The housing 10 can be formed by splicing steel structures or by assembling injection-molded materials; this application does not limit the shape or material of the housing 10.

[0047] The printing table 33 can be a planar table structure set in the receiving space 10a. The printing table 33 can be used to support the printing material to be processed, so that the printing material can be stably laid on the printing table 33 to perform printing operations, thereby realizing the precise printing operation of the inkjet printing device 100.

[0048] The printing assembly 30 may include a print head and a drive device. The drive device drives the print head to move above the print table 33, so that the printing assembly 30 can move on the print table 33 according to a set program. The print head sprays ink onto the printing material, so that the ink forms the desired image or text on the printing material, thus realizing the printing operation of the inkjet printing device 100.

[0049] The ink cartridge assembly 50 can store a certain amount of ink. By providing an ink supply line 40 within the receiving space 10a to connect the ink cartridge assembly 50 and the printing assembly 30, ink can be delivered to the printing assembly 30 via the ink supply line 40 according to the operational needs of the inkjet printing device 100, thereby enabling inkjet printing by the inkjet printing device 100. The ink cartridge assembly 50 can be a bottle-shaped or box-shaped storage container, or it can be an irregularly shaped storage container. This application does not limit the shape and material of the ink cartridge assembly 50.

[0050] By placing the ink cartridge assembly 50 within the receiving space 10a of the housing 10, the various components of the inkjet printer 100 can be stably housed within the housing 10, achieving an integrated design for the inkjet printer 100. This effectively avoids the external design of the ink cartridge assembly 50 on the housing 10, reduces the space occupied by the inkjet printer 100 during packaging and storage, and enables more convenient factory packing and storage of the inkjet printer 100, effectively improving the practicality and structural reliability of the inkjet printer 100. Meanwhile, the built-in ink cartridge assembly 50 allows the ink supply line 40 to be stably arranged within the receiving space 10a, better preventing the ink supply line 40 from passing through the housing 10. This also prevents the ink supply line 40 from being suspended outside the housing 10 and connected to the ink cartridge assembly 50, reducing the impact of the external environment on the ink supply line 40 and its loose placement outside the housing 10. This further reduces the risk of damage or leakage to the ink supply line 40, resulting in a more stable and reliable overall structural design for the inkjet printer 100. The ink cartridge assembly 50 can arrange multiple ink cartridges 51 horizontally or vertically within the receiving space 10a. Alternatively, the multiple ink cartridges 51 can be staggered within the receiving space 10a. This application does not limit the assembly method of the ink cartridge assembly 50 within the receiving space 10a.

[0051] The ink cartridge assembly 50 can be located at the rear of the printing assembly 30, and at least part of the ink supply line 40 can be located at the rear of the printing assembly 30. This facilitates the easier accommodation of the ink cartridge assembly 50 and the ink supply line 40 in the rear space of the printing assembly 30, reduces the operational interference between the printing assembly 30 and the ink cartridge assembly 50 in the accommodation space 10a, and ensures stable printing operation of the printing assembly 30 in the housing 10. By extending the ink supply line 40 located behind the printing component 30 along the moving direction of the printing component 30, the ink supply line 40 can be arranged in a U-shaped or S-shaped manner in the moving direction of the printing component 30. This allows the ink supply line 40 to retract or expand as the printing component 30 moves, maintaining the flow of ink within the ink supply line 40. This effectively prevents the ink supply line 40 from tangling or knotting, reduces blockage or ink condensation, ensures the stable installation of the ink supply line 40 within the housing space, and improves the structural stability and reliability of the inkjet printing device 100.

[0052] Meanwhile, by utilizing the ink cartridge assembly 50 and the ink supply line 40 located on the rear side of the printing assembly 30, the rear space of the printing assembly 30 can be developed and utilized. This allows for the installation of the controller of the inkjet printing device 100 and the storage of the internal transmission wires of the inkjet printing device 100. This enables the inkjet printing device 100 to achieve a more compact overall structural design, better improves the integrated performance of the inkjet printing device 100, effectively avoids the external placement of components of the inkjet printing device 100, and further reduces the space occupied by the inkjet printing device 100 during packaging and storage. This facilitates more convenient factory packaging and storage of the inkjet printing device 100, effectively improving the practicality and structural reliability of the inkjet printing device 100.

[0053] The technical solution of the present invention arranges the ink cartridge assembly 50 and the ink supply line 40 within the receiving space 10a of the housing 10 to better achieve the overall integrated design of the inkjet printing device 100. This eliminates the need for a loose layout of the ink supply line 40 connecting the ink cartridge assembly 50 and the printing assembly to cooperate with the external ink cartridge assembly 50, allowing the ink supply line 40 to be more neatly and securely arranged within the receiving space 10a, thus better reducing the risk of ink leakage from the ink supply line 40. By extending the ink supply line 40 located behind the printing component 30 along the direction of movement of the printing component 30, this part of the ink supply line 40 can retract or expand as the printing component 30 moves, thus reducing the pulling effect of the ink supply line 40 on the printing component 30 during operation. This effectively prevents the ink supply line 40 from getting tangled or knotted in the receiving space 10a, reducing the possibility of pipe blockage. As a result, the ink can be stably delivered to the printing component 30, ensuring the stable operation of the inkjet printing device 100 and effectively improving the integrity and structural reliability of the inkjet printing device 100.

[0054] Referring to Figures 2 and 3, in one embodiment of the present invention, the inkjet printing apparatus 100 further includes a filter assembly 70, which is disposed within the receiving space 10a and located on one side of the printing assembly 30 and the ink cartridge assembly 50 in the direction of movement; the ink supply line 40 includes a first line 41 and a second line 43, the first line 41 connecting the ink cartridge assembly 50 and the filter assembly 70, and the second line 43 connecting the filter assembly 70 and the printing assembly 30, and the second line 43 is at least partially disposed on the rear side of the printing assembly 30.

[0055] In this embodiment, the inkjet printing device 100 may further include a filter assembly 70, which can filter and remove impurities from the flowing ink, allowing the inkjet printing device 100 to supply relatively pure ink to the printing assembly 30 for printing. This results in clearer and more accurate printing, further improving the practicality and reliability of the inkjet printing device 100. The filter assembly 70 may include, but is not limited to, a metal mesh filter, a disc filter, or a capsule filter. This application does not limit the form and shape of the filter assembly 70.

[0056] The filter assembly 70 can be positioned on one side of the printing assembly 30 and the ink cartridge assembly 50 along the direction of movement, allowing for a more compact structural layout of the filter assembly 70, ink cartridge assembly 50, and printing assembly 30 within the receiving space. This facilitates avoidance of other components of the inkjet printing device 100, further improving the structural stability and reliability of the inkjet printing device 100. The ink supply line 40 can be configured such that, depending on the installation position of the filter assembly 70, a first line 41 connects the ink outlet of the ink cartridge assembly 50 to the ink inlet of the filter assembly 70 within the receiving space 10a, and a second line 43 connects the ink outlet of the filter assembly 70 to the ink inlet of the printing assembly 30 within the receiving space 10a, ensuring stable ink supply from the ink supply line 40. At this time, a certain limiting structure can be used in the receiving space 10a to limit the first pipe 41, so as to better prevent the first pipe 41 from loosening and ensure the stable delivery of ink; while the second pipe 43 can be set on the rear side of the printing component 30 with the side connected to the printing component 30 through the moving direction, and this part of the pipe can be extended along the moving direction of the printing component 30, so that the second pipe 43 can be better retracted or extended with the movement of the printing component 30, avoiding the second pipe 43 from tangling and knotting, reducing the blockage of the ink supply pipe 40 or the ink condensation, better ensuring the stable delivery of ink, and further improving the practicality and structural reliability of the inkjet printing device 100.

[0057] Referring to Figures 1 to 3, the inkjet printing device 100 can have a bracket 181 installed inside the housing 10. Part of the bracket 181 can be mounted above the print table 33. The printing assembly 30 can be installed on the bracket 181, allowing it to move on the bracket 181 and perform printing operations on the print table 33. Using the printing assembly 30 mounted on the bracket 181 improves the stability and reliability of the printing assembly 30 within the housing 10, ensuring stable operation of the inkjet printing device 100. In this case, the inkjet printing device 100 can form a gap between the bracket 181 and the print table 33 to allow printing material to be transferred to the print table 33 for printing operations. Alternatively, the bracket 181 can be connected to the print table 33, allowing printing material to be transported from the side of the print table 33 onto the print table. This application does not limit the installation method of the bracket 181 and the print table 33.

[0058] Referring to Figures 2 and 3, in one embodiment of the present invention, the inkjet printing device 100 includes a support frame 11 and an ink cartridge. The support frame 11 is disposed in the receiving space 10a and located on the upper side of the bracket 181, and the ink cartridge assembly 50 is disposed on the support frame 11.

[0059] In this embodiment, the inkjet printing device 100 may have a support frame 11 installed inside the housing 10. This support frame 11 can be a support plate, bracket, or other structure connected and fixed to the inner wall of the housing 10, or it can be a tray installed in the receiving space 10a using a column. This application does not limit the structural form of the support frame 11, as long as it can support the ink cartridge assembly 50. Furthermore, the support frame 11 can be correspondingly installed on the upper side of the bracket 181, so that the ink cartridge assembly 50 can be stably assembled on the support frame 11. Using the support frame 11 to support and carry the ink cartridge assembly 50 allows the ink cartridge assembly 50 to be more neatly arranged in the receiving space 10a, reducing the random stacking of the ink cartridge assembly 50 and facilitating better arrangement and installation of the various components within the inkjet printing device 100, further improving the practicality and structural reliability of the inkjet printing device 100. By positioning the support frame 11 above the bracket 181, the ink cartridge assembly 50 can be positioned above the printing assembly 30. This allows the ink cartridge assembly 50 to use gravity to deliver ink to the printing assembly 30 through the ink supply line 40, enabling more convenient ink output from the ink cartridge assembly 50. This simplifies the structural design of the inkjet printing device 100 and further improves its practicality and structural reliability.

[0060] In this embodiment, the ink cartridge assembly 50 can be arranged in a multiple ink cartridge 51 structure and placed on the support frame 11. Alternatively, the ink cartridge assembly 50 and the support frame 11 can be connected by a structure such as a snap-fit ​​or hook to ensure the stable placement of the ink cartridge assembly 50 on the support frame 11. Of course, in other embodiments, the ink cartridge assembly 50 can also be assembled and placed on the support frame 11 in other ways, as long as it can achieve stable assembly of the ink cartridge assembly 50 on the support frame 11. This application does not limit this.

[0061] Referring to Figures 2 and 6, in one embodiment of the present invention, a mounting groove 111 extending in a direction parallel to the moving direction of the printing assembly 30 is formed on the support frame 11. The ink cartridge assembly 50 includes a plurality of ink cartridges 51, which are arranged sequentially in the mounting groove 111 in a direction parallel to the moving direction.

[0062] Understandably, the ink cartridge assembly 50 can be equipped with several ink cartridges 51, using different ink cartridges 51 to store ink of different colors, so that the ink cartridge assembly 50 can supply ink of multiple colors to the print head of the print assembly 30, achieving the multi-color printing effect of the inkjet printing device 100. At this time, the support frame 11 can be provided with a mounting groove 111 extending in a direction parallel to the moving direction of the print assembly 30, so that several ink cartridges 51 can be arranged sequentially in the mounting groove 111 in a direction parallel to the moving direction, so that the space occupied by the ink cartridge assembly 50 and the space required by the print assembly 30 are arranged in parallel, better avoiding the messy assembly of the ink cartridge assembly 50 and the print assembly 30 in the housing space 10a, so that the inkjet printing device 100 can achieve a better overall compact design, and thus better facilitate the miniaturization design of the inkjet printing device 100. The ink cartridge assembly 50 allows several ink cartridges 51 to abut and limit each other, so that the ink cartridge assembly 50 can be more stably placed on the support frame 11. At the same time, by placing several ink cartridges 51 in a certain order, the ink color contained in each ink cartridge 51 can be more intuitively distinguished, and the ink cartridge assembly 50 can be disassembled and refilled with ink, further improving the operation convenience and practicality of the inkjet printing device 100.

[0063] Referring to Figures 6 and 7, in one embodiment of the present invention, a wire groove 113 is also formed on the support frame 11. The wire groove 113 is located on one side of the mounting groove 111 and communicates with the mounting groove 111. The wire groove passes through the side wall of the support frame 11, and the ink supply line 40 passes through the wire groove 113.

[0064] In this embodiment, the support frame 11 can be provided with a cable guide 113 on one side of the mounting groove 111. The cable guide 113 can be located near the ink supply port of the ink cartridge 51. By connecting the cable guide 113 with the mounting groove 111, the ink supply lines 40 connecting each ink cartridge 51 and the printing assembly 30 can be accommodated in the cable guide 113 for routing. This helps to reduce the disordered arrangement of the ink supply lines 40 in the receiving space 10a under the receiving effect of the cable guide 113, realize the limited arrangement of the ink supply lines 40 in the receiving space 10a, and reduce the interference of the ink supply lines 40 with other components. This allows the various components of the inkjet printing device 100 to achieve a more regular installation arrangement, further improving the structural stability and reliability of the inkjet printing device 100.

[0065] In this arrangement, several ink cartridges 51 are arranged sequentially along the extension direction of the mounting groove 111. At this time, the ink supply pipeline 40 may include several first pipelines 41 that are respectively connected to several ink cartridges 51. One first pipeline 41 can be connected to one ink cartridge 51, and the ink supply pipelines 40 can be stacked sequentially in the wiring groove. This facilitates the corresponding disassembly and assembly of each ink cartridge 51, prevents misconnection of pipelines between ink cartridges 51, ensures stable ink supply from the ink cartridge assembly 50 to the printing assembly 30, and further improves the structural stability and reliability of the inkjet printing device 100.

[0066] When the inkjet printing device 100 is equipped with a filter assembly 70 to filter the ink output from the ink cartridge assembly 50, the filter assembly 70 is located on one side of the ink cartridge assembly 50 and the printing assembly 30 along the moving direction. It can be installed by using a cable tray 113 to pass through the side wall of the support frame 11, so that the first pipe 41 of the ink supply line 40 connecting the ink cartridge assembly 50 and the filter assembly 70 can pass horizontally out of the support frame 11 and connect to the filter assembly 70 within the cable tray 113. This better reduces the bending of the ink supply line 40, so that the ink supply line 40 can better maintain a straight pipe state within the receiving space 10a, further improving the structural stability and reliability of the inkjet printing device 100.

[0067] Referring to Figures 2 and 3, in one embodiment of the present invention, a first partition 131 is provided inside the housing 10, and the filter assembly 70 and the ink cartridge assembly 50 are respectively disposed on opposite sides of the first partition 131, with the filter assembly 70 installed on the first partition 131.

[0068] It is understood that the housing 10 may have a first partition 131 on one side of the printing assembly 30 and the ink cartridge assembly 50 along the direction of movement. This partition 131 can separate the printing area for the printing assembly 30 to perform printing operations and the storage area for other components such as the filter assembly 70 within the receiving space 10a. The printing area and the storage area are arranged sequentially in the left-right direction, allowing the inkjet printing device 100 to achieve a cleaner and more organized layout. In this case, the inkjet printing device 100 can install the filter assembly 70 on the side of the first partition 131 opposite to the ink cartridge assembly 50 and the printing assembly 30, allowing the first partition 131 to separate the ink cartridge assembly 50 from the filter assembly 70. The first conduit 41 connecting the ink cartridge assembly 50 and the filter assembly 70 can pass through the first partition 131, ensuring a stable ink supply from the ink cartridge assembly 50 to the printing assembly 30. The inkjet printer 100 can be connected and installed on the first partition 131 by fasteners such as bolts and screws, so that the filter assembly 70 can be set more stably and reliably inside the housing 10; or, a clamp can be set on a partition to hold and fix the filter assembly 70, preventing the filter assembly 70 from falling off, and making it easier to assemble and disassemble the filter assembly 70 on the first partition 131. Of course, there are many ways to assemble the filter assembly 70, and this application does not limit this one, as long as the filter assembly 70 can be stably installed inside the housing 10.

[0069] Furthermore, by using the first partition 131 to separate the ink cartridge assembly 50 and the filter assembly 70, the ink cartridge assembly 50 and the filter assembly 70 can be better partitioned within the housing space 10a. This facilitates the independent disassembly and maintenance of multiple components of the inkjet printing device 100, reduces the stacking and assembly of various components of the inkjet printing device 100, makes the overall structure of the inkjet printing device 100 more organized, facilitates maintenance, and further improves the practicality and reliability of the inkjet printing device 100.

[0070] Referring to Figures 2 and 3, in one embodiment of the present invention, the ink cartridge assembly 50 includes a plurality of ink cartridges 51, which are arranged in a direction parallel to the moving direction; the filter assembly 70 includes a plurality of filters 71; and the ink supply line 40 includes a plurality of first lines 41, with each first line 41 connected to an ink cartridge 51 and a filter 71.

[0071] In this embodiment, the filter assembly 70 can be configured with a corresponding number of filters 71 to correspond to the number of ink cartridges 51 in the ink cartridge assembly 50. That is, the filter assembly 70 can be configured with several filters 71 connected one-to-one with several ink cartridges 51 in the ink cartridge assembly 50. At this time, one first pipe 41 of the ink supply pipe 40 can be connected to one filter 71 and one ink cartridge 51, ensuring independent filtration of each ink cartridge 51 in the ink cartridge assembly 50, reducing ink mixing, so that the inkjet printing device 100 can achieve a more accurate and reliable printing effect, further improving the practicality and reliability of the inkjet printing device 100, and ensuring the stable operation of the inkjet printing device 100.

[0072] The filters 71 can be arranged sequentially on the first partition 131 in a certain order, which facilitates a more intuitive and convenient connection of each filter 71, avoids the ink supply lines 40 from being tangled or misconnected within the housing 10, ensures stable ink supply from the ink cartridge assembly 50 to the printing assembly 30, and further improves the structural stability and reliability of the inkjet printing device 100. The filters 71 can be arranged sequentially on the first partition 131 in a front-to-back direction; or, they can be arranged sequentially on the first partition 131 in a vertical direction. If the number of filters 71 is too large, they can be arranged in multiple straight lines, or multiple filters 71 can be arranged in a staggered manner in a certain direction. This application does not limit the arrangement of the filters 71 in the filter assembly 70, as long as the filter assembly 70 can be neatly installed within the housing space 10a.

[0073] Referring to Figures 2 and 3, in one embodiment of the present invention, the inkjet printing device 100 further includes a cable chain 15, which is disposed on the rear side of the printing component 30 and below the ink cartridge component 50. One end of the cable chain 15 is connected to the printing component 30, and the other end of the cable chain is fixed. A wiring space is provided inside the cable chain 15, and a second conduit 43 passes through the wiring space.

[0074] In this embodiment, the cable chain 15 can be connected and mounted on the printing assembly 30 at one end, and fixedly connected to the housing 10 at the other end. By extending the cable chain 15 along the moving direction of the printing assembly 30, the cable chain 15 can swing to a certain extent as the printing assembly 30 moves back and forth to perform printing operations. By placing the cable chain 15 on the rear side of the printing assembly 30 and below the ink cartridge assembly 50, the second pipeline 43 connecting the filter assembly 70 and the printing assembly 30 can pass through the wiring space of the cable chain 15. This allows the cable chain 15 to play a certain role in restraining the pipeline, preventing the pipeline from colliding and interfering with other components within the receiving space 10a as the printing assembly 30 moves. At the same time, the cable chain can limit the second pipeline 43 to retract or expand together with the movement of the printing assembly 30, which can better ensure the stable operation of the inkjet printing device 100, making the various components within the inkjet printing device 100 more neatly and compactly arranged, and further improving the practicality and structural reliability of the inkjet printing device 100.

[0075] In addition, the cable carrier 15 provides a space for the transmission wires of the printing component 30 to run through, which also allows the cable carrier 15 to restrain and protect the wires inside the inkjet printing device 100. This effectively prevents the ink supply lines 40 and wires from being misaligned, reduces interference and entanglement between the ink supply lines 40 and wires and other components, ensures the stable operation of the inkjet printing device 100, and further improves the structural stability and reliability of the inkjet printing device 100.

[0076] Referring to Figures 3 to 5, in one embodiment of the present invention, the inkjet printing device 100 further includes two pressure blocks 17, which are respectively disposed near the two ends of the drag chain 15 and press and limit the second pipeline 43 and the wire.

[0077] In this embodiment, the inkjet printing device 100 can also be provided with pressure blocks 17 at both ends near the cable chain 15. The pressure blocks 17 can be used to press and limit the second pipe 43 and wire entering and exiting the wiring space, which helps to reduce the vibration of the second pipe 43 and wire in the wiring space, prevent the cable chain 15 from being dragged by the second pipe 43 and wire, ensure that the second pipe 43 and wire are arranged more stably in the receiving space 10a, and further improve the structural stability and reliability of the inkjet printing device 100.

[0078] One of the pressure blocks 17 can be connected to the printing assembly 30, allowing the pressure block 17 to press the second conduit 43 and wires that pass through the cable chain 15 and connect to the printing assembly. When a second partition 133 is provided inside the housing 10 below the cable chain, one end of the cable chain 15 can be connected to the second partition 133. In this case, another pressure block 17 can be connected to the second partition 133, and the pressure block 17 is provided with a wire hole for the second conduit 43 and wires to pass through. This allows the pressure block 17 to better press the second conduit 43 and wires, achieving stable limiting of the second conduit 43 and wires passing through the wiring space, better reducing the impact of the cable chain swinging on the second conduit 43 and wires, and achieving more stable and reliable operation of the inkjet printing device 100, further improving the structural stability and reliability of the inkjet printing device 100.

[0079] Referring to Figures 2, 10, and 13, in one embodiment of the present invention, the printing apparatus further includes an ink stack assembly 61, which is disposed within the receiving space 10a and on one side of the printing table 33 in the direction of movement. The printing assembly 30 is movable to and cooperates with the ink stack assembly 61. The ink stack assembly 61 is used to maintain the printing assembly 30, including cleaning and / or moisturizing.

[0080] In this embodiment, the ink stack assembly 61 can be used to clean and / or moisturize the printing assembly 30, which helps to prevent ink from condensing and clogging the printhead, thus ensuring the stable operation of the printing assembly 30. The ink stack assembly 61 can clean the printing assembly in various ways, such as scraping to remove condensed ink from the printing assembly 30, or using a cleaning agent to clean the printing assembly 30. Of course, combinations of cleaning methods are also possible, such as scraping followed by cleaning. This application does not limit the cleaning method of the ink stack assembly 61, as long as it can effectively clean the printing assembly 30.

[0081] The ink stack assembly 61 can be set on one side of the print station 33 along the moving direction of the print assembly 30, so that the print assembly 30 can be moved from the print station 33 to the ink stack assembly 61 for cleaning or standby, which is conducive to a more compact structural design of the inkjet printing device 100.

[0082] In one embodiment of the present invention, the ink cartridge assembly 50 includes a water supply tank, and the ink supply pipeline 40 further includes a water delivery pipeline, which connects the water supply tank and the ink stack assembly 61.

[0083] In this embodiment, the ink cartridge assembly 50 can also integrate a water supply tank for storing clean water or cleaning fluid, so that the water supply tank and several ink cartridges 51 are arranged as a whole, achieving a better compact layout of the various components of the inkjet printing device 100. At this time, the ink supply pipeline 40 can be integrated with the water supply pipeline, and the water supply pipeline can be used to connect the water supply tank and the ink stack assembly 61, so that the ink stack assembly 61 can receive a stable supply of clean water or cleaning fluid. This allows the ink stack assembly 61 to better use clean water or cleaning fluid to clean and maintain the printing assembly 30, achieving better maintenance of the ink stack assembly 61 and further improving the practicality and structural reliability of the inkjet printing device 100.

[0084] Referring to Figure 2, in one embodiment of the present invention, the inkjet printing device 100 further includes an ink extraction assembly 90, which is disposed on the rear side of the printing assembly 30 and located below the ink cartridge assembly 50; the inkjet printing device 100 also includes a suction line, which connects the ink extraction assembly and the ink stack assembly 61, so that the ink stack assembly 61 forms a negative pressure, and the ink in the ink cartridge assembly 50 flows into the printing assembly 30 through the ink supply line 40.

[0085] In this embodiment, the ink extraction component 90 can be connected to the ink stack component 61 via a suction pipe. The ink extraction component 90 generates a suction force, creating a negative pressure environment in the ink stack component 61. When the printing component 30 rests on the ink stack component 61, the negative pressure drives ink from the ink cartridge component 50 through the ink supply pipe 40 to the printing component 30. During this flow, the ink displaces air within the ink supply pipe 40, allowing for smoother ink delivery from the ink cartridge component 50 to the printing component 30, ensuring a stable ink supply to the inkjet printing device 100. The ink extraction component 90 effectively ensures a stable ink supply during the printing process of the printing component 30, resulting in a simpler structural design for the inkjet printing device 100. Simultaneously, the ink stack component 61 effectively cleans condensed ink clumps from the printing component 30, leading to a more stable and reliable printing effect and further improving the practicality and structural reliability of the inkjet printing device 100.

[0086] By positioning the ink extraction component 90 below the ink cartridge component 50, the ink extraction component 90 can be located behind the print stage 33, making it closer to the ink stack component 61. This allows for better arrangement of the suction lines below the print stage 33, reducing interference and collisions between the suction lines and other components. This results in a more reliable and compact layout design for the inkjet printing device 100, further improving its practicality and structural reliability.

[0087] Referring to Figures 2 and 3, in one embodiment of the present invention, a second partition 133 is provided inside the housing 10, and the ink cartridge assembly 50 and the ink extraction assembly 90 are respectively disposed on opposite sides of the second partition 133.

[0088] In this embodiment, the inkjet printing device 100 may have a second partition 133 installed inside the housing 10. This second partition may be located on the rear side of the printing assembly 30, and can be used to divide a portion of the rear area of ​​the printing assembly 30 vertically. This facilitates separating the ink extraction assembly 90 and the ink cartridge assembly 50 on opposite sides of the second partition 133, making the overall design of the inkjet printing device 100 more neat and aesthetically pleasing, and achieving a more compact overall design. When a drag chain 15 is installed on the rear side of the printing assembly 30 to limit the second conduit 43, the drag chain 15 and the ink extraction assembly 90 can be located on opposite sides of the second partition 113, with one end of the drag chain 15 connected to the second partition 113. This allows the various components of the inkjet printing device 100 to be more securely installed and arranged within the housing space 10a, enabling more stable operation of each component and ensuring stable printing operations of the inkjet printing device 100.

[0089] Referring to Figures 2 and 3, in one embodiment of the present invention, the ink extraction assembly 90 includes a plurality of pumps 91, which are arranged sequentially along the moving direction of the printing assembly 30.

[0090] In this embodiment, the ink extraction assembly 90 can be equipped with several pumps 91, so that the ink extraction assembly 90 can use multiple pumps to respectively achieve the functions of creating negative pressure in the ink stack assembly 61 and sucking up the waste ink generated by the ink stack assembly 61, ensuring the stable operation of the ink extraction assembly 90 and further improving the practicality and structural reliability of the inkjet printing device 100.

[0091] At this time, by arranging several pumps 91 sequentially along the moving direction of the printing assembly 30, the ink extraction assembly 90 and the printing assembly 30 can be arranged in parallel within the receiving space 10a, so that the various components of the inkjet printing device 100 can be installed and arranged more regularly and compactly within the receiving space 10a, which facilitates the miniaturization design of the inkjet printing device 100 and further improves the practicality and structural reliability of the inkjet printing device 100.

[0092] Referring to Figures 2, 10, and 13, in one embodiment of the present invention, the inkjet printing apparatus 100 further includes a waste ink cartridge 63, which is disposed within the receiving space 10a and adjacent to the ink stack assembly 61. The waste ink cartridge 63 is located on one side of the print stage 33 in the direction of movement of the printing assembly 30. The inkjet printing apparatus 100 also includes a drain pipe that connects the ink stack assembly 61 and the waste ink cartridge 63, and connects the ink extraction assembly 90 to the waste ink cartridge 63, so as to extract waste liquid from the ink stack assembly 61 to the waste ink cartridge 63.

[0093] In this embodiment, the inkjet printing device 100 can also be equipped with a waste ink box 63 in the receiving space 10a. The ink extraction assembly 90 and the ink stack assembly 61 are connected by a drain pipe, and the drain pipe is connected to the ink extraction assembly 90 and the waste ink box 63. This allows the waste ink generated by the ink stack assembly 61 to be extracted and discharged into the waste ink box 63 for collection under the action of the ink extraction assembly 90, so as to ensure the stable operation of the ink stack assembly 61, prevent the waste liquid in the ink stack assembly 61 from accumulating and overflowing, and further improve the practicality and structural reliability of the inkjet printing device 100. By placing the waste ink cartridge 63 on one side of the printing assembly 30 in the direction of movement and adjacent to the ink stack assembly 61, the various components of the inkjet printing device 100 can be made closer and more compact. This allows the ink extraction assembly 90, the ink stack assembly 61, and the waste ink cartridge 63 to be better arranged in the lower region of the receiving space 10a, reducing interference between the suction pipe, the drain pipe, and the ink supply pipe 40. This results in a more reasonable and compact component layout for the inkjet printing device 100, facilitating the miniaturization design of the inkjet printing device 100 and further improving its practicality and structural reliability.

[0094] In this way, the inkjet printing device 100 can connect the ink cartridge assembly 50 and the printing assembly 30 through the ink supply pipeline 40 for ink supply. At the same time, under the action of the suction pipeline, the ink extraction assembly 90 can create negative pressure on the ink stack assembly 61 to draw ink from the ink cartridge assembly 50 and stably deliver it to the printing assembly 30 through the ink supply pipeline 40. Furthermore, the water supply pipeline can connect the water tank of the ink cartridge assembly 50 and the ink stack assembly 61 for water supply to ensure the cleanliness of the printing assembly 30 by the ink stack assembly 61. Additionally, the waste ink of the ink stack assembly 61 can be discharged by connecting the ink stack assembly 61, the ink extraction assembly 90, and the waste ink cartridge 63 through the drain pipeline. Thus, the inkjet printing device 100 can form a relatively complete pipeline system within the housing space 10a. The position setting of each component can make the response pipeline more regular and reliable, reduce mutual interference between pipelines, and further improve the structural stability and reliability of the inkjet printing device 100.

[0095] Referring to Figure 10, in one embodiment of the present invention, the housing 10 is provided with a first operation port 12 on one side of the printing assembly 30 in the direction of movement. The first operation port 12 is disposed opposite to the ink stack assembly 61 and the waste ink cartridge 63. The inkjet printing device 100 also includes a first door 121, which is movably installed on the housing to open or close the first operation port 12. The inkjet printing device 100 also includes a first opening and closing detection component (not shown), which is disposed on the housing 10 and can cooperate with the first door 121 to detect the opening and closing state of the first door 121.

[0096] In this embodiment, by providing a first operation port 12 on one side of the housing 10, the ink stack assembly 61 and the waste ink cartridge 63 can be operated through the first operation port 12, facilitating the installation and removal of the waste ink cartridge 63 from the housing, and making it easier to inspect and maintain the ink stack assembly 61, thereby further improving the operational convenience and practicality of the inkjet printing device 100. The first operation port 12 can be of a regular shape, such as a rectangle or a circle, or it can be of an irregular shape. This application does not limit the shape of the first operation port 12.

[0097] By installing a first door 121 on the housing 10 to cover or open the first operating port 12, the integrity and aesthetics of the housing 10 can be better guaranteed, so that the ink stack assembly 61 and waste ink cartridge 63 can be better protected from the influence of the external environment when the inkjet printing device 100 is in operation or transported. The first door 121 can be connected to the housing 10. For example, the first door 121 can be slidably connected to the housing 10 to open or close the first operation port 12, or the first door 121 can be rotatably connected to the housing 10 to open or close the first operation port 12. Of course, the first door 121 can also not be connected to the housing 10, that is, the first door 121 and the housing 10 are separate. When it is necessary to close the first operation port 12, the first door 121 can be placed on the housing 10, and when it is necessary to open the first operation port 12, the first door 121 can be detached from the housing 10. There are many ways to connect the first door 121 and the housing 10, and this application does not limit this. In addition, when the inkjet printing device 100 also includes a filter assembly 70, the filter assembly 70 can be correspondingly provided at the first operation port 12, so that the ink stack assembly 61, waste ink cartridge 63 and filter assembly 70 can be inspected and maintained by opening the first door 121 on the housing 10, thereby realizing a more compact overall structure design and more convenient operation of the inkjet printing device 100, and further improving the practicality of the inkjet printing device 100.

[0098] By setting a first opening and closing detection component, the first opening and closing detection component can be triggered during the opening and closing of the first door 121, so that the first opening and closing detection component can detect and provide feedback in a timely manner whether the first door 121 is in an open or closed state. When the inkjet printing device 100 suddenly opens the first door 121 during operation, the first opening and closing detection component can send an opening signal of the first door 121 to the controller, so that the inkjet printing device 100 can temporarily stop the printing operation of the printing component 300 to avoid interference with the printing operation, so that the inkjet printing device 100 can achieve a more stable and accurate printing operation, and further improve the practicality and reliability of the inkjet printing device 100. The first opening and closing detection component can be a Hall sensor, with a corresponding magnetic component on the first door 121. The magnetic component is triggered by proximity to the Hall sensor to detect the opening and closing of the first door 121. Alternatively, the first opening and closing detection component can be an infrared detection device. When the first door 121 closes the first operating port 12, it blocks the infrared detection light, and when the first door 121 opens the first operating port 12, it avoids the infrared detection light, thus enabling the first opening and closing detection component to detect the opening and closing of the first door 121. Of course, there are many other structural forms of the first opening and closing detection component, and this application does not limit them.

[0099] Referring to Figures 11 and 13, in one embodiment of the present invention, the inkjet printing apparatus 100 further includes a reflector 183, which is disposed in the receiving space 10a and located on one side of the printing stage 33 in the direction of movement of the printing assembly 30. The inkjet printing assembly 100 can be moved above the reflector 183, and the reflector 183 can be opposite to the bottom of the printing assembly 30.

[0100] In this embodiment, by placing the reflective component 183 on one side of the printing table in the direction of movement of the printing component 30, the printing component 30 can be moved above the reflective component 183. The reflective component 183 may include, but is not limited to, metal parts, glass, reflective films, mirrors, etc. with a certain reflective effect. Information such as the dirt status of the print head at the bottom of the printing component 30 can be observed by the reflection of the reflective component 183. In this way, the operating status of the printing component 30 can be understood and it can be determined whether the printing component 30 needs to be maintained. This ensures that the inkjet printing device 100 can better achieve stable and reliable printing operations, and further improves the practicality and structural reliability of the inkjet printing device 100.

[0101] Referring to Figure 11, in one embodiment of the present invention, a second operating port 14 is provided on the side of the housing 10 adjacent to the reflective assembly 183. The inkjet printing device 100 also includes a second door 141, which is movably mounted on the housing 10 to open or close the second operating port 14. The inkjet printing device 100 also includes a second opening / closing detection component (not shown), which is disposed on the housing 10 and can cooperate with the second door 141 to detect the opening / closing state of the second door 141.

[0102] In this embodiment, by providing a second operating port 14 on one side of the housing 10, the reflective component 183 can be better observed through the second operating port 14. This allows the housing 10 to be stably observed and used while being supported by a better bracket structure 181, further improving the practicality and structural reliability of the inkjet printing device 100. The second operating port 14 can be of a regular shape, such as a rectangle or a circle, or it can be of an irregular shape. This application does not limit the shape of the second operating port 14.

[0103] By installing a second door 141 on the housing 10 to cover or open the second operating port 14, the integrity and aesthetics of the housing 10 can be better guaranteed, thus better preventing the reflective component 183 from being affected by the external environment during the operation or transportation of the inkjet printing device 100. The second door 141 can be connected to the housing 10, for example, by sliding the second door 141 onto the housing 10 to open or close the second operating port 14, or by rotating the second door 141 onto the housing 10 to open or close the second operating port 14. Alternatively, the second door 141 can be separate from the housing 10, meaning it can be placed on the housing 10 to close the second operating port 14 and detached from the housing 10 to open the second operating port 14. There are many ways to connect the second door 141 to the housing 10, and this application does not limit this.

[0104] By setting a second opening and closing detection component, it can be triggered during the opening and closing of the second door 141, so that the second opening and closing detection component can detect and provide feedback on whether the second door 141 is open or closed in a timely manner. When the second door 141 is suddenly opened during the operation of the inkjet printer 100, the second opening and closing detection component can send an open signal to the controller, so that the inkjet printer 100 can temporarily stop the printing operation of the printing component to avoid interference with the printing operation. This allows the inkjet printer 100 to achieve more stable and accurate printing operations, further improving the practicality and reliability of the inkjet printer 100. The second opening and closing detection component can employ a Hall sensor and have a corresponding magnetic component on the second door 141. The magnetic component is triggered by proximity to the Hall sensor to detect the opening and closing of the second door 141. Alternatively, the second opening and closing detection component can employ an infrared detection device. When the second door 141 closes the second operating port 14, it blocks the infrared detection light, and when the second door 141 opens the second operating port 14, it avoids the infrared detection light, thus enabling the second opening and closing detection component to detect the opening and closing of the two doors. Of course, there are many other structural forms of the second opening and closing detection component, and this application does not limit them.

[0105] Referring to Figure 12, in one embodiment of the present invention, the housing 10 is provided with a third operating port 161 communicating with the receiving space. The third operating port 161 is located above the printing table. The inkjet printing device 100 also includes a third door 161 and a third opening and closing detection component. The third door 161 is movably disposed on the housing 10 to open or close the third operating port 161. The third opening and closing detection component is disposed on the housing 10 and can cooperate with the third door 161 to detect the opening and closing state of the third door 161.

[0106] In this embodiment, by providing a third operation port 161 above the printing table on the housing 10, the printing effect of the printing material on the printing table 33 can be better observed through the third operation port 161, facilitating intervention in the printing process and enabling timely adjustment of the component configuration of the inkjet printing device 100, thus reducing printing waste. Simultaneously, the third operation port 161 allows for better maintenance of the printing assembly 30, reducing the need for disassembly of the inkjet printing device 100 and further improving its practicality and ease of operation. The third operation port 161 can be of a regular shape, such as a rectangle or circle, or of an irregular shape; this application does not limit the shape of the third operation port 161.

[0107] By installing a third door 161 on the housing 10 to cover or open the third operating port 161, the integrity and aesthetics of the housing 10 can be better guaranteed, so that the printing table 33 and printing components 30 can be better protected from the influence of the external environment when the inkjet printing device 100 is in operation or transported. The third door 161 can be connected to the housing 10. For example, the third door 161 can be slidably connected to the housing 10 to open or close the third operation port 161, or the third door 161 can be rotatably connected to the housing 10 to open or close the third operation port 161. Of course, the third door 161 can also not be connected to the housing 10, that is, the third door 161 and the housing 10 are separate. When it is necessary to close the third operation port 161, the third door 161 can be placed on the housing 10, and when it is necessary to open the third operation port 161, the third door 161 can be detached from the housing 10. There are many ways to connect the third door 161 and the housing 10, and this application does not limit this.

[0108] By setting a third opening and closing detection component, it can be triggered during the opening and closing of the third door 161, so that the third opening and closing detection component can detect and provide feedback on whether the third door 161 is open or closed in a timely manner. When the third door 161 is suddenly opened during the operation of the inkjet printer 100, the third opening and closing detection component can send an open signal to the controller, so that the inkjet printer 100 can temporarily stop the printing operation of the printing component to avoid interference with the printing operation. This allows the inkjet printer 100 to achieve more stable and accurate printing operations, further improving the practicality and reliability of the inkjet printer 100. The third opening and closing detection component can employ a Hall sensor and have a corresponding magnetic component on the third door 161. The magnetic component is triggered by proximity to the Hall sensor to achieve the opening and closing detection of the third door 161. Alternatively, the third opening and closing detection component can employ an infrared detection device. When the third door 161 closes the third operating port 161, it blocks the infrared detection light, and when the third door 161 opens the third operating port 161, it avoids the infrared detection light, thereby achieving the opening and closing detection of the three doors. Of course, there are many other structural forms of the third opening and closing detection component, and this application does not limit them.

[0109] Referring to Figure 1, in one embodiment of the present invention, the top surface of the housing 10 is provided with a pick-up and drop-out port 10b that communicates with the receiving space 10a, and the pick-up and drop-out port 10b is located above the ink cartridge assembly 50; the inkjet printing device 100 also includes a pick-up and drop-out cover plate 19, which can open or close the pick-up and drop-out port 10b.

[0110] In this embodiment, by providing a pick-up and drop-out port 10b that connects to the receiving space 10a on the top surface of the housing 10 and positioning the pick-up and drop-out port 10b above the ink cartridge assembly 50, the ink cartridge assembly 50 can be better extracted or installed through the pick-up and drop-out port 10b, facilitating the removal, ink filling, and replacement of the ink cartridge assembly 50 on the housing 10, and further improving the operational convenience and practicality of the inkjet printing device 100.

[0111] At this time, the inkjet printing device 100 can be equipped with a pick-up and drop cover 19 corresponding to the pick-up and drop port 10b. The pick-up and drop cover 19 can be used to close or open the pick-up and drop port 10b, so that the ink cartridge assembly 50 can be better protected by the pick-up and drop cover 19, preventing the ink cartridge assembly 50 from detaching from the housing 10 during transportation or use. At the same time, the ink cartridge assembly 50 can be extracted by removing the pick-up and drop cover 19 to expose it, ensuring that the ink cartridge assembly 50 can be easily disassembled and installed in the housing 10, ensuring the overall integrity of the inkjet printing device 100, and further improving the structural stability and reliability of the inkjet printing device 100.

[0112] The pick-and-place cover 19 can be connected to the housing 10 via a hinge or pivot, and the pick-and-place opening 10b can be opened or closed by rotating the pick-and-place cover 19; alternatively, a slide rail slider assembly can be provided between the pick-and-place cover 19 and the housing 10, so that the pick-and-place cover 19 can slide on the housing 10 to open or close the pick-and-place opening 10b; or alternatively, the pick-and-place cover 19 and the housing 10 can be set in a separate structure, and the pick-and-place opening 10b can be closed by placing the pick-and-place cover 19 on the housing 10, and the pick-and-place opening 10b can be opened by removing the pick-and-place cover 19 from the housing 10. There are many ways to connect the pick-and-place cover 19 and the housing 10, and this application does not limit this one.

[0113] Furthermore, in one embodiment of the present invention, the housing 10 is provided with a first magnetic element, and the pick-up and put-away cover 19 is provided with a second magnetic element, and the first magnetic element and the second magnetic element can be magnetically attracted together.

[0114] In this embodiment, the first magnetic component can be a magnet, and the second magnetic component can be a magnet with the opposite magnetism to the first magnetic component or a magnetically attractable metal; or, the first magnetic component can be a magnetically attractable metal, and the second magnetic component can be a magnet. Furthermore, by setting the first magnetic component at the position corresponding to the placement of the pick-up and put-down cover 19 on the housing 10, and setting the second magnetic component on the side of the pick-up and put-down cover 19 facing the housing 10, the magnetic attraction between the first magnetic component and the second magnetic component can be used to achieve convenient disassembly and assembly of the pick-up and put-down cover 19 and the housing 10, further improving the operational convenience and practicality of the inkjet printing device 100.

[0115] Referring to Figures 6 and 8, in one embodiment of the present invention, the ink cartridge assembly 50 includes a plurality of ink cartridges 51, and the ink cartridge assembly 50 further includes an ink level detection device 53, which is used to detect the ink level in the ink cartridges 51.

[0116] In this embodiment, the ink cartridge assembly 50 may also be equipped with an ink level detection device 53. This device can detect the remaining ink level in each ink cartridge 51 in a timely manner, allowing for timely refilling of ink cartridges 51 when the remaining ink level is low. This ensures adequate ink replenishment for each ink cartridge 51 and further improves the practicality and reliability of the ink cartridge assembly 50. When the ink level detection device 53 detects low ink levels in an ink cartridge 51, ink can be directly injected into the refill port of the ink cartridge 51 on the support frame 11. Alternatively, the ink cartridge 51 can be removed from the support frame 11, refilled with ink, and then reinstalled onto the support frame 11. This application does not limit the ink refilling method for the ink cartridge 51, as long as stable ink refilling is achieved.

[0117] Further, referring to Figures 8 and 9, in one embodiment of the present invention, the ink volume detection device 53 includes a sensing float 531 and a signal transmitter 533. The sensing float 531 is disposed inside the ink cartridge 51, and the signal transmitter 533 is disposed on the support frame 11 and is configured to correspond to the lifting path of the sensing float 531 inside the ink cartridge 51.

[0118] In this embodiment, the ink level detection device 53 may include a sensing float 531 and a signal transmitter 533. The signal transmitter 533 may be mounted on the support frame 11 and positioned near the bottom of the side wall of the ink cartridge 51, so that the signal transmitter 533 can be positioned to correspond to the lifting path of the sensing float 531. The sensing float 531 may be located inside the ink cartridge 51 and can move up and down with changes in the ink level inside the ink cartridge 51. Therefore, when there is a large amount of ink inside the ink cartridge 51, the sensing float 531 may be located at the top of the ink cartridge 51, thus... The sensor float 531 and the signal transmitter 533 are far apart. At this time, the signal transmitter 533 is not triggered by the sensor float 531. However, when the sensor float 531 drops to a position close to the bottom wall of the ink cartridge 51 as the ink level in the ink cartridge 51 decreases, the sensor float 531 and the signal transmitter 533 are triggered accordingly. This allows the signal transmitter 533 to send a signal that the ink level in the ink cartridge 51 is low, reminding the ink cartridge 51 to be refilled with ink. This ensures a stable ink supply from the ink cartridge assembly 50 to the inkjet printer 100, further improving the structural stability and reliability of the ink cartridge assembly 50.

[0119] Referring to Figures 8 and 9, in one embodiment of the present invention, a limiting baffle 511 is connected to the inner side wall of the ink cartridge 51. The limiting baffle 511 and the inner side wall of the ink cartridge 51 enclose a limiting guide rail 513. A sensing float 531 is vertically and flexibly disposed on the limiting guide rail 513. A signal transmitter 533 is disposed corresponding to the position of the limiting guide rail 513.

[0120] In this embodiment, by providing a limiting baffle 511 on the inner sidewall of the ink cartridge 51, the limiting baffle 511 can extend along the direction from the inner top wall to the inner bottom wall of the ink cartridge 51. The limiting baffle 511 and the inner sidewall of the ink cartridge 51 can be used to form a limiting guide rail 513 extending in the vertical direction. The limiting guide rail 513 is connected to the inner cavity of the ink cartridge 51 so that the liquid level in the ink cartridge 51 is consistent with the liquid level in the limiting guide rail 513. This allows the sensor float 531 to be installed within the limiting guide rail 513. The inner wall of the ink cartridge 51 and the limiting baffle 511 limit the sensor float 531, enabling it to move stably up and down along the limiting guide rail 513 within the ink cartridge 51. This helps prevent the sensor float 531 from shifting, ensuring stable triggering of the sensor float 531 and the signal transmitter 533, achieving stable and reliable detection of the ink level in the ink cartridge 51, and further improving the overall structural stability and reliability of the ink cartridge assembly 50.

[0121] Additionally, referring to Figure 9, in some embodiments, the sensing float 531 is provided with a magnetic element 5311, and the signal transmitter 533 is a Hall sensor.

[0122] In this embodiment, the sensing float 531 can be equipped with a structure that can emit a certain magnetic field, such as a magnet or electromagnet. In this case, the signal transmitter 533 can be a Hall sensor, so that when the sensing float 531 descends to a certain liquid level, the signal transmitter 533 can be triggered to send a corresponding control signal, ensuring stable detection of the ink level inside the ink cartridge 51. Alternatively, the signal transmitter 533 can be an infrared detection device, so that when the sensing float 531 descends to a certain position, it blocks the infrared light emitted by the signal transmitter 533, thereby causing the signal transmitter 533 to send a corresponding sensing signal. Of course, the ink level detection device 53 can also use other detection mechanisms; this application does not limit this, as long as it can achieve stable detection of the ink level inside the ink cartridge 51.

[0123] Referring to Figures 14 and 15, in one embodiment of the present invention, the inkjet printing device 100 further includes a button 80. The button 80 includes a frame 81, a key body 83, and a cantilever 85. The housing is provided with a button hole. The frame 81 is connected to the housing 10. The two ends of the cantilever 85 are respectively connected to the inner wall of the frame 81 and the outer wall of the key body 83. The cantilever 85 is elastic so that the key body 83 has a rebound force after being pressed. The key body 83 is spaced apart from the frame 81 and exposed through the button hole.

[0124] In this embodiment, by providing a button 80 at the mounting hole of the housing 10, the start and stop control of the inkjet printing device 100 can be realized by pressing the button 80, thereby achieving better control of the inkjet printing device 100. Below the button 80, a control switch for the inkjet printing device 100 can be correspondingly installed. The button body 83 can be raised and lowered within the frame 81 to trigger the opening and closing of the control switch. When the button body 83 is pressed down within the frame 81 by the elastic connection of the cantilever 85, it pulls the cantilever 85 to undergo elastic deformation, allowing the cantilever 85 to support the button body 83 as it presses down to trigger the control switch, thus starting the inkjet printing device. When the button body 83 is pressed down again, the rebound force of the cantilever 85 lifts the button body 83, separating it from the control switch and stopping the inkjet printing device 100. This achieves start / stop control of the inkjet printing device 100, further improving its practicality and structural reliability.

[0125] In addition, the key body 83 can be made of a light-transmitting material, such as acrylic or glass. In this case, an indicator light can be provided at the control switch so that the light of the indicator light can be displayed through the key body 83. This allows the user to better understand the operation of the inkjet printer 100 based on the light color or flashing characteristics of the indicator light, thereby further improving the practicality and ease of operation of the inkjet printer 100.

[0126] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
