[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0051] Various types of inkjet printers are widely used to print barcodes, two-dimensional codes, etc. on packages. When replacing ink cartridges, it is difficult to pull out the ink cartridges from the printer body of the inkjet printer provided by the related art, which is extremely inconvenient and labor-intensive.

[0052] The present embodiment provides an inkjet printer, which can conveniently disassemble and replace ink cartridges and ensures labor-saving disassembly of the ink cartridges. The inkjet printer of the present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3The inkjet printer 010 of this embodiment is a handheld inkjet printer; of course, in other embodiments, the inkjet printer 010 may also refer to a non-handheld inkjet printer, which is not specifically limited here. The inkjet printer 010 of this embodiment includes a body 100, an ink cartridge cover 300, an ink cartridge 400 and a linkage mechanism 500. The body 100 is provided with an installation space 110 and a take-in and put-out port 120 connected to the installation space 110; the ink cartridge cover 300 is movably mounted on the body 100 for opening or blocking the take-in and put-out port 120; the ink cartridge 400 is detachably mounted in the installation space 110; the linkage mechanism 500 is mounted on the body 100, and the linkage mechanism 500 is used to lock the ink cartridge cover 300 at a position blocking the take-in and put-out port 120 or to unlock the ink cartridge cover 300; wherein, when the linkage mechanism 500 is unlocked by an external force, the linkage mechanism 500 can also push the ink cartridge 400 out of the take-in and put-out port 120. When it is necessary to remove or replace the ink cartridge 400 in the installation space 110, it is only necessary to apply force to the linkage mechanism 500 to unlock the ink cartridge cover 300 and eject the ink cartridge 400, so that the user can take out the ink cartridge 400 ejected from the access port 120, thereby ensuring the convenience and effort-saving of removing the ink cartridge 400 and improving the user experience.

[0054] It should be noted that the inkjet printer 010 also includes a controller (not shown) and a functional component 200. Both the controller and the functional component 200 are arranged on the body 100, and the functional component 200 is electrically connected to the controller; the functional component 200 includes but is not limited to a code scanning component, a built-in electric eye component, a red light roller component and a color mark sensor, etc. The way in which the functional component 200 is assembled on the body 100 includes but is not limited to a fixed connection and a detachable connection.

[0055] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6The linkage mechanism 500 includes an unlocking member 510, a locking member 520 and an ejection assembly 530. The unlocking member 510 can be movably assembled on the body 100. The unlocking member 510 and the locking member 520 are in transmission cooperation. The locking member 520 cooperates with the ink cartridge cover 300 to lock the ink cartridge cover 300 at a position covering the access port 120, or separates from the ink cartridge cover 300 to unlock the ink cartridge cover 300. The ejection assembly 530 can be movably arranged on the body 100 and in transmission cooperation with the unlocking member 510. When the unlocking member 510 drives the locking member 520 to separate from the ink cartridge cover 300 under the action of external force, the unlocking member 510 can also drive the ejection assembly 530 to eject the ink cartridge 400 from the access port 120. When it is necessary to remove or replace the ink cartridge 400 in the installation space 110, it is only necessary to apply force to the unlocking member 510 to unlock the ink cartridge cover 300 through the locking member 520, so that the access port 120 can be opened. At the same time, the unlocking member 510 can also be used to link the ejection assembly 530 to eject the ink cartridge 400 from the access port 120. In this way, it is convenient for the user to remove the ink cartridge 400 ejected from the access port 120, ensuring the convenience and effort-saving of disassembling the ink cartridge 400 and improving the user experience.

[0056] The ink cartridge cover 300 can be assembled to the body 100 in a manner that can be selected as needed; Figure 3 , Figure 5 and Figure 7 In this embodiment, the pivot end of the ink cartridge cover 300 is rotatably connected to the body 100, so that the unlocked ink cartridge cover 300 can be moved to a position to open or cover the access opening 120 by rotating; the ink cartridge cover 300 is rotatably connected to the body 100, on the one hand, to ensure the flexibility of the ink cartridge cover 300, and on the other hand, the ink cartridge cover 300 does not need to be completely separated from the body 100 when the access opening 120 is opened, and thus no additional storage for the ink cartridge cover 300 is required, thereby ensuring convenience.

[0057] In order to enable the unlocked ink cartridge cover 300 to switch to the position of opening the access port 120 more efficiently, the inkjet printer 010 also includes a third elastic member 320, which is configured to elastically cooperate with the ink cartridge cover 300; when the ink cartridge cover 300 blocks the access port 120, the third elastic member 320 undergoes elastic deformation; when the ink cartridge cover 300 is unlocked, the third elastic member 320 resets under its own elastic action, and the ink cartridge cover 300 rotates to the open access port 120 under the elastic action of the third elastic member 320.

[0058] Optionally, the pivot end of the ink cartridge cover 300 is rotatably connected to the body 100 via the first rotating shaft 321, the third elastic member 320 is a torsion spring, the torsion spring is sleeved on the first rotating shaft 321, one torsion arm of the torsion spring is connected to the ink cartridge cover 300, the other torsion arm is connected to the body 100, or both torsion arms of the torsion spring are connected to the body 100. The connection method of the torsion arm of the torsion spring with the ink cartridge cover 300 or the body 100 includes but is not limited to snap connection, bonding, and plug connection.

[0059] Of course, in other embodiments, the third elastic member 320 may also be a tension spring, etc., which is not specifically limited here.

[0060] In other embodiments, the ink cartridge cover 300 may also be slidably connected to the body 100, which is not specifically limited herein.

[0061] It should be noted that the ink cartridge cover 300 opening the access opening 120 only means that the access opening 120 is no longer blocked, so that the ink cartridge 400 can enter and exit through the access opening 120, rather than the ink cartridge cover 300 being completely separated from the access opening 120, that is, when the ink cartridge cover 300 opens the access opening 120, the ink cartridge cover 300 leaves the access opening 120, but can still be located above the access opening 120 at a distance. The ink cartridge cover 300 blocking the access opening 120 means that the ink cartridge cover 300 can block the ink cartridge 400 from entering and exiting the access opening 120 at the access opening 120, rather than the ink cartridge cover 300 completely closing the access opening 120; of course, in other embodiments, the ink cartridge cover 300 blocking the access opening 120 may also mean that the ink cartridge cover 300 completely closes the access opening 120.

[0062] Please refer to Figure 3 and Figure 6 In this embodiment, the locking member 520 is a second buckle, and the unlocking member 510 is engaged with or separated from the hook 302 connected to the end of the ink cartridge cover 300 through the second buckle. When the unlocking member 510 is engaged with the ink cartridge cover 300 through the second buckle, the ink cartridge cover 300 is locked in a position that blocks the access port 120; when the unlocking member 510 is separated from the ink cartridge cover 300 through the second buckle, the ink cartridge cover 300 is unlocked and can be rotated to a position that opens the access port 120.

[0063] Of course, in other embodiments, the locking member 520 may also be a plug-in member, and the unlocking member 510 may also be connected to or separated from the ink cartridge cover 300 through the plug-in member, which is not specifically limited here.

[0064] Optionally, see Figure 3 and Figure 6The body 100 is also provided with an assembly hole 111, which is communicated with the installation space 110, and the unlocking member 510 can be slidably inserted into the assembly hole 111; when the unlocking member 510 is pressed by an external force, the unlocking member 510 can extend from the assembly hole 111 into the installation space 110, and drive the locking member 520 to separate from the ink cartridge cover 300; when the unlocking member 510 is retracted from the assembly hole 111, the locking member 520 can cooperate with the ink cartridge cover 300.

[0065] Of course, in other embodiments, the unlocking member 510 can also be a toggle member. When the unlocking member 510 is toggled in a direction away from the ink cartridge cover 300 under the action of an external force, it can also be separated from the ink cartridge cover 300, so that the ink cartridge cover 300 is unlocked and the ejection assembly 530 is driven to eject the ink cartridge 400 from the access port 120.

[0066] Optionally, in some embodiments, the inkjet printer 010 further includes a fourth elastic member (not shown), which is connected between the unlocking member 510 and the body 100, or between the unlocking member 510 and the ejection assembly 530; when the unlocking member 510 is pressed by an external force and separated from the ink cartridge cover 300, the fourth elastic member is pressed by the unlocking member 510 and elastically deformed, and when the unlocking member 510 is not pressed, the fourth elastic member is reset under its own elastic action and drives the unlocking member 510 to reset. The fourth elastic member includes but is not limited to a spring and a torsion spring.

[0067] Please refer to Figure 2 and Figure 3 In this embodiment, the inkjet printer 010 further includes a detection component 310, which is disposed on the body 100; when the ink cartridge cover 300 blocks the access opening 120, the detection component 310 cooperates with the ink cartridge cover 300; when the ink cartridge cover 300 opens the access opening 120, the detection component 310 separates from the ink cartridge cover 300. The setting of the detection component 310 facilitates the user to accurately determine whether the ink cartridge cover 300 is normally closed based on the detection result fed back by the detection component 310, thereby avoiding the problem that the user uses the inkjet printer 010 when the ink cartridge cover 300 is not normally closed, thereby accidentally damaging the inkjet printer 010.

[0068] Furthermore, the detection component 310 is arranged near the unlocking piece 510, and the end of the ink cartridge cover 300 that cooperates with or separates from the locking piece 520 is connected to the detection column 301. When the ink cartridge cover 300 is located in a position to block the access port 120, the detection column 301 can cooperate with the detection component 310 to enable the detection component 310 to form an electronic signal; when the ink cartridge cover 300 is located in a position to open the access port 120, the detection column 301 is separated from the detection component 310, and the detection component 310 no longer forms an electronic signal (that is, the electronic signal disappears).

[0069] The detection component 310 can be a micro switch, a laser sensor, a pressure sensor, etc., which is not specifically limited here.

[0070] Optionally, the inkjet printer 010 also includes a display 611 arranged on the body 100. The display 611 and the detection component 310 are electrically connected to the controller. The detection component 310 can send an electronic signal to the controller. After receiving the electronic signal, the controller can control the display 611 to display an indication that the ink cartridge cover 300 is normally closed.

[0071] Optionally, the ink cartridge 400 is provided with a detection chip, and the body 100 is also provided with a detection component, which is electrically connected to the controller. The detection component is used to identify the detection chip, and when the detection component identifies the detection chip, the detection component sends a signal to the controller indicating that the ink cartridge 400 is assembled in place.

[0072] Please refer to Figure 8 The ejection assembly 530 of this embodiment includes an ejector rod 540 and a second rotating shaft 544. The ejector rod 540 is rotatably connected to the body 100 through the second rotating shaft 544. The ejector rod 540 has a first end and a second end opposite to each other. The first end of the ejector rod 540 is in transmission cooperation with the unlocking member 510. When the unlocking member 510 is unlocked by an external force, the unlocking member 510 can also drive the ejector rod 540 to rotate, so that the ink cartridge 400 is pushed out of the access port 120 by the second end of the ejector rod 540. The setting of the rotatable ejector rod 540 is conducive to ejecting the ink cartridge 400 from the access port 120 with more effort, thereby improving the user experience.

[0073] Please refer to Figure 2 , Figure 3 and Figure 8 , further, the push rod 540 is rotatably mounted in the installation space 110; the ink cartridge 400 has a first end close to the pivot end of the ink cartridge cover 300 and a second end away from the pivot end of the ink cartridge cover 300, the rotation axis of the push rod 540 is spaced apart from the second end of the ink cartridge 400, and the rotation axis of the push rod 540 is located below the detection component 310 and above the bottom of the ink cartridge 400, specifically, the second rotation axis 544 is spaced apart from the second end of the ink cartridge 400, and the second rotation axis 544 is located below the detection component 310 and above the bottom of the ink cartridge 400. Such a configuration, on the one hand, can utilize the limited installation space 110 of the fuselage 100 to assemble the push rod 540, ensure the compactness of the structure, and facilitate the miniaturization design of the inkjet printer 010, and on the other hand, it is more conducive to the effortless ejection of the ink cartridge 400 from the access port 120 by rotating the push rod 540.

[0074] Optionally, the functional component 200 is disposed close to the pivot end of the ink cartridge cover 300 , that is, the functional component 200 is disposed close to the first end of the ink cartridge 400 .

[0075] Please refer to Figure 6 In this embodiment, the locking member 520 is connected to the first end of the push rod 540 and is integrally formed with the push rod 540 to reduce the assembly process of the inkjet printer 010.

[0076] Of course, in other embodiments, the locking member 520 may also be connected to the first end of the push rod 540 by bonding, threaded connection, etc., which is not specifically limited here.

[0077] In other embodiments, the locking member 520 may also be connected to the unlocking member 510; or the locking member 520 may also be movably connected to the body 100 and located between the unlocking member 510 and the first end of the push rod 540, but the locking member 520 is not connected to either the unlocking member 510 or the push rod 540, and is not specifically limited here.

[0078] Optionally, see Figure 8 The ejection assembly 530 further includes an ejection protrusion 541, which is connected to the second end of the ejector rod 540 and protrudes relative to the ejector rod 540 toward the direction close to the ink cartridge 400. The ejection protrusion 541 can abut against the ink cartridge 400, that is, when the ejector rod 540 rotates under the action of the unlocking member 510, the ejection protrusion 541 can abut against the ink cartridge 400, so that the ink cartridge 400 is ejected from the access port 120. By setting the ejection protrusion 541, when the rotating ejector rod 540 is needed to eject the ink cartridge 400 from the access port 120, the rotation range (rotation angle) of the ejector rod 540 is reduced, which is conducive to ejecting the ink cartridge 400 in a narrow installation space 110, thereby ensuring the compact structure of the inkjet printer 010.

[0079] Optionally, the ejection protrusion 541 is connected to the ejector rod 540 at an angle, and the angle between the two can be selected as needed, for example: 90°, 100°, 120°, 80°, etc., which is not specifically limited here.

[0080] Optionally, see Figure 8 The ejection assembly 530 also includes an ejection protrusion 542, which is connected to the end of the ejection protrusion 541 away from the ejector rod 540, and the ejection protrusion 542 protrudes relative to the ejection protrusion 541 along the extension direction of the set axis, and the set axis is parallel to the rotation axis of the ejector rod 540, and the ejection protrusion 542 can abut against the ink cartridge 400, that is, when the ejector rod 540 rotates under the action of the unlocking member 510, the ejection protrusion 541 and the ejection protrusion 542 can jointly abut against the ink cartridge 400, so that the ink cartridge 400 is ejected from the access port 120; the provision of the ejection protrusion 542 increases the contact area with the ink cartridge 400, so that the ink cartridge 400 can be more stably and reliably ejected from the access port 120.

[0081] The connection method of the ejector pin 540, the ejector protrusion 541 and the ejector bump 542 can be selected as needed; in this embodiment, the connection method of the ejector pin 540, the ejector protrusion 541 and the ejector bump 542 is integrally formed. Of course, in other embodiments, the connection method of the ejector pin 540, the ejector protrusion 541 and the ejector bump 542 can also be bonding or threaded connection.

[0082] Please refer to Fig. 9 In this embodiment, the unlocking member 510 is provided with a first mating inclined surface 511, and the first end of the push rod 540 is provided with a second mating inclined surface 546; when the unlocking member 510 is pressed, the first mating inclined surface 511 and the second mating inclined surface 546 are abutted, and the first mating inclined surface 511 and the second mating inclined surface 546 slide and cooperate with each other; such a setting can ensure that the unlocking member 510 drives the push rod 540 to rotate smoothly, thereby ensuring that the ink cartridge 400 can be smoothly pushed out of the access port 120 by the push rod 540.

[0083] Please refer to Figure 2 and Figure 3 In this embodiment, the body 100 is provided with a limiting groove 130, and the push rod 540 is movably provided in the limiting groove 130, and the push rod 540 can abut against or separate from the groove wall of the limiting groove 130; wherein, when the push rod 540 pushes the ink cartridge 400 out of the access opening 120 under the drive of the unlocking member 510, the push rod 540 can abut against the groove wall of the limiting groove 130. In this way, the groove wall of the limiting groove 130 can be used to limit the rotation range of the push rod 540, so as to improve the problem of excessive rotation of the push rod 540.

[0084] Optionally, see Figure 6 The ejection assembly 530 further includes a second elastic member 543, which is configured to be elastically matched with the ejector rod 540; when the unlocking member 510 drives the ejector rod 540 to rotate under the action of an external force, the second elastic member 543 undergoes elastic deformation; when the unlocking member 510 is not affected by an external force, the second elastic member 543 is reset under its own elastic action, and drives the ejector rod 540 to reset, and the ejector rod 540 resets the locking member 520 and the unlocking member 510. In this way, the second elastic member 543 is conveniently used to improve the reset efficiency and stability of the ejector rod 540, the locking member 520 and the unlocking member 510, so that when the ink cartridge 400 is reinstalled, it is not hindered by the ejector rod 540, the installation efficiency of the ink cartridge 400 is improved, and it is ensured that the ink cartridge cover 300 can be reliably locked at a position that blocks the access port 120.

[0085] Please refer to Figure 8 and Fig.10, further, the second elastic member 543 is a torsion spring, the body 100 is provided with a first slot 112, and the first slot 112 is located in the installation space 110, and the push rod 540 is provided with a second slot 545; the torsion spring is sleeved on the second rotating shaft 544, one of the torsion arms of the torsion spring is clamped in the second slot 545, and the other torsion arm is clamped in the first slot 112; when the push rod 540 pushes the ink cartridge 400 out of the access port 120 under the action of the unlocking member 510, the torsion spring undergoes elastic deformation, and when the unlocking member 510 is no longer subjected to external force, the torsion spring is reset under its own elastic action, and the push rod 540 is reset, and the locking member 520 and the unlocking member 510 are driven to reset. Of course, in other embodiments, one of the two torsion arms of the torsion spring is clamped in the first slot 112 or the second slot 545, and the other can also be connected to the slot wall of the limiting slot 130, which is not specifically limited here.

[0086] In this embodiment, the distance L1 from the first end of the push rod 540 to the second rotating shaft 544 is smaller than the distance L2 from the second end of the push rod 540 to the second rotating shaft 544; in this way, the problem that when the ink cartridge 400 is ejected by the push rod 540, the force applied by the push rod 540 to the ink cartridge 400 is too large, causing the ink cartridge 400 to fly out directly from the loading and unloading port 120 and fall, resulting in damage to the ink cartridge 400 can be improved.

[0087] The distance from any end of the push rod 540 to the second rotating shaft 544 refers to the distance from any end of the push rod 540 to the rotation center of the second rotating shaft 544. Of course, in other embodiments, the distance from any end of the push rod 540 to the second rotating shaft 544 refers to the shortest distance from any end of the push rod 540 to the outer peripheral wall of the second rotating shaft 544.

[0088] Optionally, the distance from the second end of the push rod 540 to the second rotation axis 544 is at least 1.5 times the distance from the first end of the push rod 540 to the second rotation axis 544 .

[0089] In other embodiments, please refer to Fig.11 In order to further improve the effort-saving effect of pressing the unlocking member 510 to drive the push rod 540 to push the ink cartridge 400 out of the loading and unloading port 120, the distance L1 from the first end of the push rod 540 to the second rotating shaft 544 is configured to be larger than the distance L2 from the second end of the push rod 540 to the second rotating shaft 544, that is, the distance L2 from the second end of the push rod 540 to the second rotating shaft 544 is less than 1 times the distance L1 from the first end of the push rod 540 to the second rotating shaft 544; in this way, the purpose of effort saving can be achieved by increasing the length of the force arm of the force-applying end.

[0090] Alternatively, in other embodiments, the distance from the first end of the push rod 540 to the second rotation axis 544 may also be equal to the distance from the second end of the push rod 540 to the second rotation axis 544 .

[0091] In this embodiment, the straight-line distance H1 from the second rotating shaft 544 to the second end of the ink cartridge 400 is greater than the straight-line distance H2 from the second rotating shaft 544 to the detection component 310; such a configuration can ensure that sufficient space is left in the installation space 110 for the second end of the push rod 540 to rotate, thereby ensuring that the second end of the push rod 540 can rotate smoothly to push the ink cartridge 400 out of the access port 120.

[0092] Optionally, the straight-line distance from the second rotating shaft 544 to the second end of the ink cartridge 400 is at least 1.5 times the straight-line distance from the second rotating shaft 544 to the detection assembly 310 .

[0093] In other embodiments, the straight-line distance from the second rotating shaft 544 to the second end of the ink cartridge 400 may also be less than or equal to the straight-line distance from the second rotating shaft 544 to the detection component 310 .

[0094] When the inkjet printer 010 of this embodiment is in use, the ink cartridge cover 300 can be first rotated to open the access port 120, and the ink cartridge 400 can be assembled in the installation space 110 through the access port 120, and then the ink cartridge cover 300 can be rotated to cover the access port 120; when the ink cartridge 400 needs to be replaced, the unlocking member 510 is pressed, and the locking member 520 is separated from the ink cartridge cover 300 by using the unlocking member 510, and the ejection assembly 530 is driven by the unlocking member 510 to eject the ink cartridge 400 from the access port 120, so that the user can take the ink cartridge 400 out of the access port 120.

[0095] In summary, the inkjet printer 010 of the present invention can disassemble and replace the ink cartridge 400 more conveniently, saves more effort when disassembling the ink cartridge 400, and provides a good user experience.

[0096] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
