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

[0051] Various types of inkjet printers are widely used to print barcodes, QR codes, etc. on packaging. When replacing the ink cartridge, it is difficult to pull the ink cartridge out of the printer body, which is extremely inconvenient and labor-intensive.

[0052] The present embodiment provides an inkjet printer that can conveniently disassemble and replace ink cartridges and ensures that the ink cartridges can be disassembled with less effort. The inkjet printer of the present embodiment will be described in detail below with reference to 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 an access opening 120 connected to the installation space 110. The ink cartridge cover 300 is movably mounted on the body 100 for opening or blocking the access opening 120. The ink cartridge 400 is detachably mounted in the installation space 110. The linkage mechanism 500 is mounted on the body 100 and is used to lock the ink cartridge cover 300 in a position blocking the access opening 120 or to unlock the ink cartridge cover 300. When the linkage mechanism 500 is unlocked by an external force, the linkage mechanism 500 can also eject the ink cartridge 400 from the access opening 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, 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. The controller and the functional component 200 are both 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 is 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 in a position blocking the access port 120, or separates from the ink cartridge cover 300 to unlock the ink cartridge cover 300. The ejection assembly 530 is movably provided on the body 100 and is 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 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 removing 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 pivotal 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 of opening or covering the access opening 120 by rotation; the rotatable connection of the ink cartridge cover 300 to the body 100 ensures the flexibility of the ink cartridge cover 300 on the one hand, 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 position of opening the 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 a first rotating shaft 321. The third elastic member 320 is a torsion spring, which is sleeved on the first rotating shaft 321. One torsion arm of the torsion spring is connected to the ink cartridge cover 300, and the other torsion arm is connected to the body 100, or both torsion arms of the torsion spring are connected to the body 100. Methods for connecting the torsion arms of the torsion spring to the ink cartridge cover 300 or the body 100 include, but are not limited to, snap-fitting, gluing, and plugging.

[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 merely means that the access opening 120 is no longer blocked, allowing the ink cartridge 400 to enter and exit 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 moves away from the access opening 120, but can still be positioned above the access opening 120 at a distance. The ink cartridge cover 300 blocking the access opening 120 refers to the ink cartridge cover 300 being able to 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 blocking the access opening 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 opening 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] Alternatively, see Figure 3 and Figure 6The body 100 is also provided with an assembly hole 111, which is connected to 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 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 elastically deformed by the pressure of the unlocking member 510. When the unlocking member 510 is no longer pressed, the fourth elastic member returns to its original position under its own elastic force, thereby causing the unlocking member 510 to return to its original position. The fourth elastic member includes, but is not limited to, a spring or a torsion spring.

[0067] Please refer to Figure 2 and Figure 3 In this embodiment, the inkjet printer 010 further includes a detection assembly 310, which is disposed on the body 100. When the ink cartridge cover 300 blocks the access port 120, the detection assembly 310 engages with the ink cartridge cover 300; when the ink cartridge cover 300 opens the access port 120, the detection assembly 310 separates from the ink cartridge cover 300. The provision of the detection assembly 310 allows the user to accurately determine whether the ink cartridge cover 300 is properly closed based on the test results provided by the detection assembly 310, thereby preventing the user from accidentally damaging the inkjet printer 010 by using the ink cartridge cover 300 when it is not properly closed.

[0068] Furthermore, the detection component 310 is arranged near the unlocking member 510, and the end of the ink cartridge cover 300 that cooperates with or separates from the locking member 520 is connected to the detection column 301. When the ink cartridge cover 300 is located in a position that blocks 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 that opens the access port 120, the detection column 301 is separated from the detection component 310, and the detection component 310 no longer generates 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 a push rod 540 and a second rotating shaft 544. The push rod 540 is rotatably connected to the body 100 via the second rotating shaft 544. The push rod 540 has a first end and a second end that are opposite each other. The first end of the push rod 540 is in driving engagement with the unlocking member 510. When the unlocking member 510 is applied with an external force to unlock the ink cartridge cover 300, the unlocking member 510 can also drive the push rod 540 to rotate, so that the ink cartridge 400 is pushed out of the access opening 120 by the second end of the push rod 540. The provision of a rotatable push rod 540 facilitates more labor-saving ejection of the ink cartridge 400 from the access opening 120, thereby improving the user experience.

[0073] Please refer to Figure 2 、 Figure 3 and Figure 8 Furthermore, the ejector rod 540 is rotatably mounted within the installation space 110. The ink cartridge 400 has a first end proximal to the pivotal end of the ink cartridge cover 300 and a second end distal to the pivotal end of the ink cartridge cover 300. The rotation axis of the ejector rod 540 is spaced apart from the second end of the ink cartridge 400 and is located below the detection assembly 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 is located below the detection assembly 310 and above the bottom of the ink cartridge 400. This arrangement not only allows the ejector rod 540 to be mounted within the limited installation space 110 of the printer body 100, ensuring a compact structure and facilitating the miniaturization of the inkjet printer 010, but also facilitates the effortless ejection of the ink cartridge 400 from the access opening 120 by rotating the ejector 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, threading, 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] Alternatively, 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 in a 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 opening 120. The provision of the ejection protrusion 541 makes it easier to reduce the rotation range (rotation angle) of the ejector rod 540 when the rotating ejector rod 540 is needed to eject the ink cartridge 400 from the access opening 120, thereby facilitating the ejection of the ink cartridge 400 in a narrow installation space 110 and 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] Alternatively, 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. 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 ejected from the access port 120 more stably and reliably.

[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 ejector pin 540, the ejector protrusion 541, and the ejector bump 542 are integrally formed. Of course, in other embodiments, the ejector pin 540, the ejector protrusion 541, and the ejector bump 542 can also be connected by bonding or threading.

[0082] Please refer to Figure 9 In this embodiment, the unlocking member 510 is provided with a first mating inclined surface 511, and the first end of the ejector 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 abut against each other, 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 ejector rod 540 to rotate smoothly, thereby ensuring that the ink cartridge 400 can be smoothly ejected from the access port 120 by the ejector rod 540.

[0083] Please refer to Figure 2 and Figure 3 In this embodiment, the housing 100 is provided with a limit slot 130, and the ejector 540 is movably disposed within the limit slot 130. The ejector 540 can abut against or separate from the wall of the limit slot 130. Specifically, when the ejector 540 is driven by the unlocking member 510 to eject the ink cartridge 400 from the access opening 120, the ejector 540 abuts against the wall of the limit slot 130. This allows the wall of the limit slot 130 to limit the rotation range of the ejector 540, thereby alleviating the problem of excessive rotation of the ejector 540.

[0084] Alternatively, see Figure 6 The ejection assembly 530 further includes a second elastic member 543, which is configured to elastically cooperate with the ejector pin 540. When the unlocking member 510 drives the ejector pin 540 to rotate under the action of an external force, the second elastic member 543 elastically deforms. When the unlocking member 510 is no longer under the action of an external force, the second elastic member 543 returns to its original position under its own elastic action, driving the ejector pin 540 to return to its original position. The ejector pin 540 then returns the locking member 520 and the unlocking member 510 to their original position. This arrangement facilitates utilizing the second elastic member 543 to improve the efficiency and stability of the return of the ejector pin 540, the locking member 520, and the unlocking member 510. This facilitates reinstallation of the ink cartridge 400 without being hindered by the ejector pin 540, thereby improving the efficiency of the ink cartridge 400 installation and ensuring that the ink cartridge cover 300 can be securely locked in a position that blocks the access port 120.

[0085] Please refer to Figure 8 and Figure 10Furthermore, the second elastic member 543 is a torsion spring. The body 100 is provided with a first engaging slot 112, and the first engaging slot 112 is located within the installation space 110. The push rod 540 is provided with a second engaging slot 545. The torsion spring is sleeved on the second rotating shaft 544. One torsion arm of the torsion spring is engaged with the second engaging slot 545, and the other torsion arm is engaged with the first engaging 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. When the unlocking member 510 is no longer subjected to external force, the torsion spring returns to its original position under its own elastic action, causing the push rod 540 to return to its original position, and driving the locking member 520 and the unlocking member 510 to return to their original position. Of course, in other embodiments, one of the two torsion arms of the torsion spring is engaged with the first engaging slot 112 or the second engaging slot 545, and the other can also be connected to the slot wall of the limiting slot 130. This 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 either end of the push rod 540 to the second rotation axis 544 refers to the distance from either end of the push rod 540 to the rotation center of the second rotation axis 544. Of course, in other embodiments, the distance from either end of the push rod 540 to the second rotation axis 544 refers to the shortest distance from either end of the push rod 540 to the outer peripheral wall of the second rotation axis 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 Figure 11 In order to further improve the effort-saving effect of pressing the unlocking member 510 to drive the ejector rod 540 to eject the ink cartridge 400 from the access port 120, the distance L1 from the first end of the ejector rod 540 to the second rotating shaft 544 is configured to be greater than the distance L2 from the second end of the ejector rod 540 to the second rotating shaft 544, that is, the distance L2 from the second end of the ejector rod 540 to the second rotating shaft 544 is less than 1 times the distance L1 from the first end of the ejector 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 rotation of the second end of the push rod 540, thereby ensuring that the second end of the push rod 540 can rotate smoothly to push the ink cartridge 400 out of the loading and unloading port 120.

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

[0094] When the inkjet printer 010 of this embodiment is in use, the ink cartridge cover 300 can be 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 unlocking member 510 is used to separate the locking member 520 from the ink cartridge cover 300, and the unlocking member 510 is used to drive the ejection assembly 530 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 effort when disassembling the ink cartridge 400, and provides a good user experience.

[0096] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
