[0068] Inkjet printers are widely used to print barcodes, QR codes, and other codes on packaging. However, when replacing ink cartridges, conventional inkjet printers are difficult to remove, which is both inconvenient and labor-intensive. Furthermore, conventional inkjet printers often lack functionality extensions.

[0069] This embodiment provides an inkjet printer that can conveniently disassemble and replace ink cartridges and ensures that the ink cartridges are labor-saving to disassemble, and can also expand the functions of the inkjet printer.

[0070] Please refer to Figure 1 and Figure 2 The inkjet printer 010 of this embodiment is a handheld inkjet printer; of course, in other embodiments, the inkjet printer 010 may also refer to other non-handheld inkjet printers, which is not specifically limited here.

[0071] The inkjet printer 010 of this embodiment includes a body 100, and a controller 610, a display 611, a battery 612, a switch module 613, a nozzle logic drive module 614, an inkjet print head module 615, and a positioning module 616 disposed on the body 100; wherein the display 611, the battery 612, the switch module 613, the nozzle logic drive module 614, and the positioning module 616 are all electrically connected to the controller 610; the battery 612 is used to power the entire machine; the display 611 is used to display printing-related information, etc.; the switch module 613 is used to control the power on and off (i.e., turning the printer on and off) of the inkjet printer 010. ; The inkjet print head module 615 is electrically connected to the nozzle logic drive module 614, and the nozzle logic drive module 614 drives the movement of the inkjet print head module 615 under the control of the controller 610, so as to use the inkjet print head module 615 to print out the corresponding pattern; the positioning module 616 can be used to detect the position, displacement and other changes of the inkjet print head module 615, so that when printing, the positioning module 616 sends the detected displacement signal to the controller 610, and then the controller 610 controls the nozzle logic drive module 614 to drive the inkjet print head module 615 to print, thereby achieving accurate printing.

[0072] Optionally, the positioning module 616 may be a magnetoelectric encoder, a photoelectric sensor, etc., which is not specifically limited here.

[0073] Optionally, the body 100 of the inkjet printer 010 is further provided with a print button 617, which is electrically connected to the controller 610. Pressing the print button 617 can trigger a corresponding function, for example: triggering the inkjet print head module 615 to print.

[0074] Please refer to Figure 2 、 Figure 3 and Figure 4The inkjet printer 010 of this embodiment further includes 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 can be movably assembled on the body 100 for opening or blocking the access opening 120; the ink cartridge 400 can be detachably assembled in the installation space 110; the linkage mechanism 500 is assembled on the body 100, and the linkage mechanism 500 is used to lock the ink cartridge cover 300 in a position blocking the access opening 120 or unlock the ink cartridge cover 300; wherein, when the linkage mechanism 500 is unlocked by an external force so that the ink cartridge cover 300 is unlocked, the linkage mechanism 500 can also push the ink cartridge 400 out of 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.

[0075] For further information, please refer to Figure 5 、 Figure 6 and Figure 7 The 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.

[0076] The ink cartridge cover 300 can be assembled to the body 100 in a manner that can be selected as needed; Figure 4 、 Figure 6 and Figure 8In this embodiment, 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 rotating; the ink cartridge cover 300 is rotatably connected to the body 100, on the one hand, ensuring 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.

[0077] 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.

[0078] Optionally, 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.

[0079] Of course, in other embodiments, the third elastic member 320 may also be a tension spring, etc., which is not specifically limited here.

[0080] In other embodiments, the ink cartridge cover 300 may also be slidably connected to the body 100 , which is not specifically limited herein.

[0081] 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.

[0082] Please refer to Figure 4 and Figure 7In 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.

[0083] 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.

[0084] Alternatively, see Figure 4 and Figure 7 The 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.

[0085] 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.

[0086] 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.

[0087] Please refer to Figure 3 and Figure 4In 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.

[0088] 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).

[0089] The detection component 310 can be a micro switch, a laser sensor, a pressure sensor, etc., which is not specifically limited here.

[0090] Alternatively, see Figure 1 The detection component 310 is electrically connected to the controller 610. The detection component 310 can send an electronic signal to the controller 610. After receiving the electronic signal, the controller 610 can control the display 611 to display an indication that the ink cartridge cover 300 is normally closed.

[0091] 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 610. 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 610 indicating that the ink cartridge 400 is assembled in place.

[0092] Please refer to Figure 9 The ejection assembly 530 of this embodiment includes a push rod 540, which is rotatably connected to the body 100. The push rod 540 has a first end and a second end that oppose 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 unlocked by an external force, the unlocking member 510 also drives 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 rotatable push rod 540 facilitates more labor-saving ejection of the ink cartridge 400 from the access opening 120, thereby improving the user experience.

[0093] Please refer to Figure 3 、 Figure 4 and Figure 9 Furthermore, the ejector rod 540 is rotatably mounted within the installation space 110. The ink cartridge 400 has a first end proximal to the functional assembly 200 mounted on the body 100 and a second end distal to the functional assembly 200. The rotation axis of the ejector rod 540 is spaced apart from the second end of the ink cartridge 400, and the rotation axis of the ejector rod 540 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 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 the rotating ejector rod 540.

[0094] Please refer to Figure 7 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.

[0095] 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.

[0096] 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.

[0097] Alternatively, see Figure 9 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.

[0098] 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.

[0099] Alternatively, see Figure 9 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.

[0100] 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.

[0101] Please refer to Figure 3 and Figure 4 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.

[0102] Alternatively, see Figure 7 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.

[0103] Please refer to Figure 9 and Figure 10Furthermore, the second elastic member 543 is a torsion spring, and the push rod 540 is rotatably connected to the body 100 through the second rotating shaft 544. The body 100 is provided with a first card slot 112, and the first card slot 112 is located in the installation space 110, and the push rod 540 is provided with a second card slot 545; the torsion spring is sleeved on the second rotating shaft 544, one torsion arm of the torsion spring is clamped in the second card slot 545, and the other torsion arm is clamped in the first card 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 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 to the first clamping slot 112 or the second clamping slot 545, and the other can also be connected to the slot wall of the limiting slot 130, which is not specifically limited here.

[0104] Please refer to Figure 2 The inkjet printer 010 of this embodiment further includes a functional component 200 , which is disposed on the body 100 and electrically connected to the controller 610 .

[0105] In order to achieve functional expansion of the inkjet printer 010 , the functional component 200 is configured to be detachably assembled on the body 100 ; in this way, the functional components 200 with different functions can be disassembled and assembled as needed to expand the functions of the inkjet printer 010 .

[0106] It should be noted that the number of functional components 200 configured for an inkjet printer 010 can be selected as needed. Different numbers of functional components 200 can bring different numbers of functional expansions to the inkjet printer 010. Figure 1 and Figure 11For example, a printer 010 can be equipped with four functional components 200, which can be detachably assembled on the body 100. The four functional components 200 are respectively a code scanning component, a built-in electric eye component, a red light roller component and a color mark sensor; wherein, 1. After the code scanning component is installed on the body 100, pressing the print button 617 twice in succession or long pressing the print button 617 for a set time (for example, 5s, 8s, etc.) can trigger the code scanning function of the code scanning component. At the same time, the display 611 will show the picture taken by the camera of the code scanning component. After that, the scanning terminal of the code scanning component can be used to aim at the barcode or QR code. 1. After the recognition is successful, the code scanning component will be automatically closed, and the scanned string information will be displayed on the print editing interface of the display 611 through the controller 610. Then, the print button 617 will be pressed to use the inkjet print head module 615 to smoothly move and print the pattern on the printing medium or object; 2. After the built-in electric eye component is installed on the body 100, the content to be printed can be edited in the print editing interface on the display 611. After pressing the print button on the user interface (UI) on the display 611, the built-in electric eye component can be used to directly trigger the inkjet print head module 615 to print, without having to press the print button 617 separately; 3. After the red light roller assembly is installed on the body 100, the content to be printed can be input in the print editing interface displayed on the display 611, and then the print button on the user interface (UI) on the display 611 is pressed. At this time, the controller 610 performs data rendering, data matching, and sends the print data, and at the same time sends a red light opening instruction to the red light roller assembly. Then press the print button 617 to use the inkjet print head module 615 to smoothly move and print the image on the printing medium or object. During the printing process, the red light roller assembly emits at least two red lights spaced apart according to the size designed by the controller 610, so as to use the red light emitted by the red light roller assembly to print the area. Domain guidance plays a role in guiding and assisting printing; 4. After the color mark sensor is installed on the body 100, the color mark sensor can be used to sense the color that needs to trigger printing, and the corresponding information can be sent to the controller 610, so that the controller 610 can send the corresponding control information to the positioning module 616. At the same time, the content to be printed can be input in the print editing interface displayed on the display 611, and the print button on the user interface (UI) on the display 611 can be pressed. The controller 610 renders the data, matches the data, and sends the print data. When the positioning module 616 senses the color sensed and entered by the color mark sensor, printing will be triggered.

[0107] The detachable connection method between the functional component 200 and the body 100 can be selected as needed. In this embodiment, the functional component 200 is snap-fitted to the body 100. This ensures the ease of assembly and disassembly of the functional component 200 from the body 100 and the stability of the assembly of the functional component 200 to the body 100.

[0108] Of course, in other embodiments, the functional component 200 may also be detachably connected to the fuselage 100 via fasteners such as bolts.

[0109] For further information, please refer to Figure 2 、 Figure 8 、 Figure 12 and Figure 13 The functional component 200 has a first end and a second end that are relatively distributed. The first end of the functional component 200 is plugged into the body 100, and the second end of the functional component 200 is provided with a snap-fit ​​assembly 210. The snap-fit ​​assembly 210 includes a first snap 211, which is elastically assembled to the second end of the functional component 200 and snapped into or out of the body 100. The two ends of the functional component 200 are respectively configured to be plugged into and snapped into the body 100. On the one hand, this ensures the easy assembly and disassembly of the functional component 200. During assembly, the first end of the functional component 200 can be first plugged into the body 100, and then the second end of the functional component 200 can be snapped into the body 100. During disassembly, the second end of the functional component 200 can be first separated from the body 100, and then the first end of the functional component 200 can be separated from the body 100. On the other hand, this ensures the stability of the functional component 200 assembled to the body 100.

[0110] Of course, in other embodiments, the first buckle 211 may also be elastically assembled on the body 100 and be connected to or separated from the second end of the functional component 200 .

[0111] In other embodiments, the first end of the functional component 200 may also be snap-connected to the body 100 .

[0112] In this embodiment, please refer to Figure 13 The snap-fit ​​assembly 210 further includes a first elastic member 212, through which the first snap 211 is assembled to the second end of the functional assembly 200. When the first snap 211 is separated from the body 100 under the action of an external force, the first elastic member 212 undergoes elastic deformation. When the first snap 211 is no longer affected by the external force, the first elastic member 212 returns to its original position under its own elastic action, thereby driving the first snap 211 to return to its original position. The provision of the first elastic member 212 improves the stability of the snap-fit ​​connection between the functional assembly 200 and the body 100, and also ensures ease of operation when separating the first snap 211 from the body 100.

[0113] For further information, please refer to Figure 12 The functional component 200 includes a shell 220 and a functional module (not shown in the figure). The functional module is assembled on the shell 220, and the first buckle 211 is set on the shell 220 through the first elastic member 212. With such a setting, when the functional component 200 is disassembled and assembled, it will not cause adverse effects on the functional module, thereby ensuring the reliability of the function of the functional module.

[0114] Alternatively, see Figure 12 The outer shell 220 includes a first shell 221 and a second shell 222 that are buckled and connected to each other. The ends of the first shell 221 and the second shell 222 are spliced ​​to form a first avoidance hole 223. The first clip 211 is assembled on the first shell 221 through the first elastic member 212, and part of the first clip 211 extends from the first avoidance hole 223; when the functional component 200 needs to be removed from the fuselage 100, the first clip 211 can be pressed with force at the part of the first clip 211 extending from the first avoidance hole 223 to separate it from the fuselage 100, and the functional component 200 can be removed, ensuring the ease of disassembly of the functional component 200.

[0115] It should be noted that the functional module can be assembled between the first shell 221 and the second shell 222, or assembled in the first shell 221 or the second shell 222, which is not specifically limited here.

[0116] The connection method between the first shell 221 and the second shell 222 includes, but is not limited to, snap connection and connection through fasteners such as bolts.

[0117] Alternatively, see Figure 14 and Figure 15 One of the first shell 221 and the first buckle 211 is provided with a guide groove 224, and the other of the two is provided with a guide rib 225. The guide rib 225 and the guide groove 224 can be slidably plugged into each other. When the functional component 200 needs to be disassembled, an external force is applied to press the first buckle 211. Through the sliding cooperation between the guide rib 225 and the guide groove 224, the stability of the moving path of the first buckle 211 can be ensured, so as to ensure that the first buckle 211 is smoothly separated from the fuselage 100, and when the external force applied to the first buckle 211 is removed, the first buckle 211 can be smoothly reset under the action of the first elastic member 212 without being easily deviated, thereby ensuring the stability of the first buckle 211 when it is reset to the clamping connection with the fuselage 100, thereby ensuring the stability of the functional component 200 assembled on the fuselage 100.

[0118] Alternatively, see Figure 13 and Figure 14 The first shell 221 is also provided with a positioning groove 226, and the first elastic member 212 is inserted into the positioning groove 226; in this way, when the first elastic member 212 is compressed or restored, the deformation of the first elastic member 212 can be improved, which causes the elastic action of the first elastic member 212 to be difficult to stably act on the first buckle 211 and the problem of stable reset of the first buckle 211.

[0119] The number of first elastic members 212 and the number of positioning slots 226 can be selected as needed. For example, the first housing 221 is provided with two positioning slots 226, each of which is provided with a first elastic member 212, and both first elastic members 212 are elastically engaged with the first buckle 211. Of course, in other embodiments, the number of positioning slots 226 and first elastic members 212 can be one, three, etc., and are not specifically limited here.

[0120] The first elastic member 212 may be an elastic rubber column, a spring, a torsion spring, etc., which is not specifically limited here.

[0121] It should be understood that in other embodiments, the snap-fit ​​assembly 210 may also include only the first snap 211. The first snap 211 may be made of a material that is elastic itself so that it can be directly elastically assembled on the functional component 200. The above-mentioned elastic material may refer to elastic metal, plastic, etc., and the first snap 211 may be a spring with a snap-fit ​​structure, etc.

[0122] In other embodiments, the first end of the functional component 200 can also be snapped to the body 100 through the snap-on component 210, or other positions between the first end and the second end of the functional component 200 can also be snapped to the body 100, etc., which are not specifically limited here.

[0123] In order to ensure that the functional component 200 is assembled on the body 100, the electrical connection between the functional component 200 and the controller 610 can be achieved quickly, efficiently and conveniently; Figure 16 and Figure 17 In this embodiment, the functional component 200 is provided with a first conductive member 201, and the body 100 is provided with a second conductive member 101. The first conductive member 201 is electrically connected to the functional module, and the second conductive member 101 is electrically connected to the controller 610. The first conductive member 201 and the second conductive member 101 are connected or separated, that is, when the functional component 200 is assembled on the body 100, the first conductive member 201 and the second conductive member 101 can be directly aligned to achieve electrical connection, so that the functional module of the functional component 200 can be electrically connected to the controller 610.

[0124] Optionally, the first conductive member 201 is a metal contact electrically connected to the functional module, and the metal contact is exposed from the second avoidance hole 227 set in the second shell 222; the second conductive member 101 is a PIN needle electrically connected to the controller 610, and the PIN needle is exposed to the body 100; when the functional component 200 is assembled on the body 100, the PIN needle contacts the metal contact to achieve electrical connection.

[0125] Of course, in other embodiments, the first conductive member 201 may be a PIN pin, and the second conductive member 101 may be a metal contact.

[0126] When using the inkjet printer 010 of this embodiment, 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; then the functional component 200 to be used can be selected and assembled on the body 100.

[0127] Use the switch module 613 to turn on the device (for example, the switch module 613 includes a switch button. Press and hold the switch button for 3 seconds to turn on the device. If you press and hold the switch button for 3 seconds in the power-on state, the display 611 will pop up a window to prompt whether to turn off the device, so that you can manually confirm the shutdown. Alternatively, press and hold the switch button for 5 seconds in the power-on state to directly turn off the device).

[0128] It should be noted that the ink cartridge 400 and the functional component 200 can be assembled before or after the power is turned on.

[0129] Before inkjet printing, you can add and edit the content to be printed (for example: text, pictures, QR codes, barcodes, numbers, time, databases, etc.) in the print editing area of ​​the display 611. After editing the content, press the print button on the user interface (UI); then, the controller 610 starts to render the print content, match the print parameters, generate print data and send it to the nozzle logic drive module 614, waiting for the nozzle logic drive module 614 to control the inkjet print head module 615 to print (for example: wait for the user to press the print button 617 on the body 100 before starting printing).

[0130] To sum up, 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; moreover, the functions of the inkjet printer 010 can be expanded by disassembling and assembling different functional components 200 in a convenient manner.

[0131] 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.
