[0054] The utility model provides a mounting seat 1, an inkjet print head 100 and an inkjet printer. The mounting seat 1 is used to install an ink cartridge, which can make it more convenient for a user to disassemble and install the ink cartridge 2 and avoid ink contamination.

[0055] Please refer to Figures 1 to 5 In some embodiments of the present application, an inkjet print head 100 includes a mounting seat 1 and an ink cartridge 2, the mounting seat 1 is provided with a shell 10, the shell includes an outer shell 11, a mounting cavity 111 is formed in the outer shell 11, and the outer shell 11 has a bottom opening 113 and a side opening 112 connected to the mounting cavity 111; wherein the ink cartridge 2 can enter and exit the mounting cavity 111 from the side opening 112, and the nozzle 210 of the ink cartridge 2 is exposed through the bottom opening 113.

[0056] Specifically, in the embodiment of the present application, the inkjet print head 100 is defined to have a height direction, and the nozzle 210 of the ink cartridge 2 in the inkjet print head 100 is usually arranged downward to eject ink downward for printing. In the inkjet print head 100 proposed in the embodiment of the present application, the mounting seat 1 includes a housing 10, and the housing 10 is a cavity-type structure, and its structural outline is roughly a rectangular parallelepiped or cube-like multi-prism structure, and of course it can also be other regular or irregular structures. The shell 10 includes an outer shell 11 and a side cover 13. An installation cavity 111 is formed in the outer shell 11. A bottom opening 113 connected to the installation cavity 111 is provided on the bottom surface of the outer shell 11, wherein the bottom opening 113 is provided in a partial area of ​​the bottom surface of the mounting seat 1, and can be used to expose the nozzle 210 of the ink cartridge 2, and can be slightly larger than the nozzle 210 of the ink cartridge 2; at the same time, a side opening 112 connected to the installation cavity 111 is provided on the side of the mounting seat 1, and the side opening 112 can be covered and closed by the side cover 13; the side cover 13 can be detachably connected to the outer shell 11, or can be rotatably connected or slidably connected to the outer shell 11, so that the side wall opening is exposed by removing the side cover 13, flipping the side cover 13 or sliding the side cover 13.

[0057] The ink cartridge 2 is the main structure of the inkjet print head 100, which is used to store ink and receive control signals to gradually eject the ink from the nozzle 210; the inkjet form of the ink cartridge 2 can be piezoelectric inkjet technology or thermal inkjet technology. In actual application, the ink cartridge 2 enters the installation cavity 111 from the side opening 112 of the shell 11, and aligns the nozzle 210 with the bottom opening 113; the shell 11 supports the ink cartridge 2 in a manner that a support surface is provided so that the area on the bottom surface of the ink cartridge 2 where the nozzle 210 is not provided is supported on the support surface, or a slot is provided on the side wall of the installation cavity 111, and a plug-in structure is provided on the side wall of the ink cartridge 2, so that the plug-in structure is inserted in the slot, and the shell 111 can also support the ink cartridge 2. After the ink cartridge 2 enters the installation cavity 111, the side cover 13 is covered on the side opening 112 to prevent the ink cartridge 2 from falling out of the installation cavity 111 or being displaced; it can also prevent foreign objects from entering the installation cavity 111. In the embodiment of the present application, only the side cover 13 can be used to cover the side opening 112 to limit and fix the ink cartridge 2. A connecting structure can also be set between the ink cartridge 2 and the mounting seat 1, such as a snap connection, a magnetic connection, a card strip limiting connection, an adhesive or other connecting structure, to improve the connection strength between the ink cartridge 2 and the mounting seat 1 and improve the position stability of the ink cartridge 2.

[0058] In some embodiments, the housing 10 further includes a side cover 13, which can be opened and closed at the side opening 112. When the ink cartridge 2 needs to be replaced or the nozzle 210 and other structures need to be cleaned or maintained, the side cover 13 is opened to expose the side opening 112, and the user grabs the side of the ink cartridge 2 from the side opening 112 to remove the ink cartridge 2 from the installation cavity 111 or install it into the installation cavity 111; in this way, the user will not touch the nozzle 210 at the bottom of the ink cartridge 2, thereby avoiding ink staining on the hands. The side cover 13 can be slidably connected to the housing 11 to open and close the side opening 112 by sliding the side cover 13; or the side cover 13 can be rotatably connected to the housing 11 to open and close the side opening 112 by rotating the side cover 13.

[0059] In some embodiments, a gap connected to the side opening 112 can be opened on the side wall of the mounting base 1 adjacent to the side opening 112, so that when the side cover 13 is opened, part of the side wall of the ink cartridge 2 on both sides of the side opening 112 can be exposed for the user to grab the ink cartridge 2.

[0060] Therefore, it can be understood that in the technical solution of the present application, the inkjet print head 100 detachably mounts the ink cartridge 2 in the mounting cavity 111 of the mounting seat 1, and the nozzle 210 of the ink cartridge 2 can be exposed from the bottom opening 113 of the mounting seat 1 to spray ink outward. By providing a side opening 112 on the side of the housing 11, the ink cartridge 2 can be removed from the side opening 112 or installed into the mounting cavity 111, so that the user is prevented from contacting the nozzle 210 at the bottom of the ink cartridge 2 when removing and installing the ink cartridge 2, thereby preventing the ink from getting on the user's hands.

[0061] When there is no need to disassemble the ink cartridge 2, the side cover 13 can be sealed on the side opening 112 to improve the overall structural stability when the ink cartridge 2 is installed on the mounting seat 1, prevent the ink cartridge 2 from falling out or shifting, and prevent foreign matter from entering the mounting cavity 111 through the side opening 112, thereby reducing the risk of damage to the ink cartridge 2.

[0062] Please refer to Figure 5 In some embodiments of the present application, the mounting base 10 further includes a locking structure 14, which is disposed on the outer shell 11, and one end of the side cover 13 is detachably connected to the outer shell 11 through the locking structure 14, and the other end of the side cover 13 is rotatably connected to the outer shell 11.

[0063] In the present embodiment, one side of the side cover 13 is detachably connected to the outer shell 11. Taking the rotational connection between the side cover 13 and the mounting base 1 as an example, the side of the side cover 13 that is rotationally connected to the mounting base 1 is defined as the rotational side. The side of the side cover 13 adjacent to the rotational side can be detachably connected to the mounting base 1, or the side of the side cover 13 opposite to the rotational side can be detachably connected to the mounting base 1. The detachable connection method between the side cover 13 and the mounting base 1 can be at least one of magnetic connection, snap connection, bonding, bolt connection or binding with binding parts. With such a configuration, the side cover 13 can be stably covered on the side opening 112 without opening the side opening 112.

[0064] In this embodiment, the side cover 13 can be rotatably connected to the mounting seat 1 at the top side or bottom side in the height direction of the inkjet print head 100, and at this time, the side cover 13 can be flipped up and down relative to the mounting seat 1 to open or close the side opening 112; or any side of the side cover 13 used to connect the top side and the bottom side can be rotatably connected to the mounting seat 1, so that the side cover 13 can be horizontally flipped relative to the mounting seat 1 to open or close the side opening 112; of course, the side cover 13 can also be a double-door structure, including two flip covers that are rotatably connected to the mounting seat 1. In this way, when the side opening 112 needs to be opened, there is no need to remove the side cover 13 as a whole, which improves the convenience of use and reduces the risk of losing the side cover 13. It can be understood that the lock release structure 14 can be used to connect any side of the side cover 13 except the rotationally connected side to the housing 11. When the side cover 13 needs to be opened, it is only necessary to release the lock of the lock release structure 14.

[0065] Please refer to Figures 9 to 11 In some embodiments of the present application, the mounting base 1 further includes a rotating shaft 15 and a torsion spring 16. The side cover 13 is rotatably connected to the housing 11 via the rotating shaft 15. The torsion spring 16 is sleeved on the rotating shaft 15. The two force arms of the torsion spring 16 are respectively in contact with the side cover 13 and the housing 11. With such a configuration, when the mounting cavity 111 needs to be opened, it is only necessary to release the lock of the side cover 13 by the lock release structure 14. At this time, the torsion spring 16 will automatically drive the side cover 13 to flip over and open the side opening 112. It is convenient to use, and the user does not need to flip over the side cover 13, thereby improving the convenience of use.

[0076] Please refer to Figure 7 In some embodiments of the present application, at least part of the driving member 142 is slidably disposed in the installation cavity 111 and has a fixed position and a release position. During the process of the driving member 142 sliding from the fixed position to the release position, the first clamping member 141 is pushed to move from the locked position to the unlocked position.

[0077] In this embodiment, the driving member 142 is connected or abutted with the first clamping member 141, and the driving member 142 is set to a slidable structure, wherein the sliding direction of the driving member 142 can be consistent with the moving direction of the first clamping member 141, or the sliding direction of the driving member 142 can be different from the moving direction of the first clamping member 141, for example, in the following embodiment, the matching structure of the inclined first driving arm 1413 is used, and the specific structure is referred to the following embodiment. In some embodiments, in order to facilitate operation, a sliding hole 115 can be opened in the side wall of the housing 11, and an operating part 1422 can be set on the driving member 142. The operating part 1422 can be a handle or a slider. The operating part 1422 is penetrated through the sliding hole 115 and extends out of the side wall of the housing 11 for user operation, so that the user can drive the driving member 142 to slide by controlling the operating part 1422.

[0078] Please refer to Figure 7 and Fig. 9 In some embodiments of the present application, the first clamping member 141 is provided with a first driving arm 1413 and a clamping arm 1414 connected to each other. The first driving arm 1413 is connected to one end of the clamping arm 1414 away from the side opening 112 and is inclined relative to the sliding direction of the driving member 142. The clamping arm 1414 is clamped with the side cover 13; the driving member 142 includes a pushing portion 1421 located in the installation cavity 111, and the pushing portion 1421 supports the first driving arm 1413 to drive the first driving arm 1413 to move when the driving member 142 slides from the fixed position to the released position, so that the clamping arm 1414 moves from the locked position to the unlocked position.

[0079] Specifically, when the driving member 142 slides from the fixed position to the release position, the pushing portion 1421 of the driving member 142 supports the first driving arm 1413, so that the first driving arm 1413 drives the clamping arm 1414 to tilt in the direction away from the driving member 142, so that the clamping arm 1414 moves to the unlocking position. When the driving member 142 slides from the release position to the fixed position, the first driving arm 1413 and the clamping arm 1414 return to their original positions under the action of the elastic force. In this way, the driving member 142 and the first clamping member 141 have different moving directions, and the moving directions of the first driving arm 1413 and the clamping arm 1414 on the first clamping member 141 are moving in the direction close to or away from the driving member 142. In this way, it is not necessary to make the sliding direction of the driving member 142 the same as the moving direction of the driving member 142, and the structures of the driving member 142 and the first clamping member 141 can be set using spaces in different directions, thereby improving the design flexibility and reducing the occupied space in the moving direction of the first clamping member 141.

[0080] Combined with reference Figure 7 and Fig.13 In some embodiments of the present application, the first clamping member 141 includes a fixing portion 1411 and a clamping portion 1412, the fixing portion 1411 is connected to the mounting seat 1, the clamping portion 1412 extends from the fixing portion 1411 to the side opening 112, and is provided with a first driving arm 1413 and a clamping arm 1414. In this configuration, the fixing portion 1411 is used to improve the connection strength between the first clamping member 141 and the mounting seat 1, and only the fixing portion 1411 of the first clamping member 141 is connected to the mounting seat 1, which will not affect the bending and deformation activities of the clamping portion 1412.

[0081] Please refer to Figure 7 and Fig.13 In some embodiments of the present application, the clamping arm 1414 is provided with a clamping interface 1416, the second clamping member 131 is provided with a hook 1311, and the first clamping member 141 also includes a second driving arm 1415, the second driving arm 1415 is connected to one end of the clamping arm 1414 close to the side opening 112, and is inclined along the direction of the driving member, and the inclination direction is opposite to the inclination direction of the first driving wall 1413; when the side cover 13 is closed on the side opening 112, the hook 1311 supports the second driving arm 1415 to make the first clamping member 141 gradually tilt up, until the hook 1311 moves to extend into the clamping interface 1416, and the first clamping member 141 is reset to the locked position so that the hook 1311 is clamped in the clamping interface 1416.

[0082] With such arrangement, when the side cover 13 is closed on the side opening 112, the second clamping member 131 will support the second driving arm 1415 so that the second driving arm 1415 drives the clamping arm 1414 to move to the unlocking position, so that the first clamping member 141 avoids the second clamping member 131 to avoid interference with the closing process of the side cover 13, so that the hook 1311 of the second clamping member 131 can move to the position of the clamping arm 1414 of the first clamping member 141; when the hook 1311 moves to the clamping arm 1414 and is arranged opposite to the clamping interface 1416, the first clamping member 141 is reset to the locking position so that the hook 1311 is clamped in the clamping interface 1416, thereby improving the convenience of closing the side cover 13.

[0083] Please refer to Figure 7 In some embodiments of the present application, the mounting base 1 further includes a reset member 143, the two ends of which are respectively connected to the housing 11 and the driving member 142, and the reset member 143 is used to make the driving member 142 have a tendency to remain in a fixed position. With such a configuration, when the side cover 13 needs to be closed on the mounting base 1, the driving member 142 is moved from the fixed position to the unlocked position under the control of the user, and then the side cover 13 is closed on the side opening 112 of the mounting base 1. At this time, it is only necessary to release the driving member 142, so that the driving member 142 can be automatically moved to the fixed position under the action of the reset member 143, so that the first clamping member 141 is reset to the locked position and is mutually clamped with the second clamping member 131 of the side cover 13, and the user no longer needs to push the driving member 142 to move to the fixed position, thereby improving the convenience of use. And by setting the reset member 143, the driving member 142 can be stably located in the fixed position, so as to ensure that the driving member 142 will not return to the release position when the first clamping member 141 and the second clamping member 131 are clamped and fixed, and avoid the first clamping member 141 and the second clamping member 131 from being separated, thereby improving the stability of the closing of the side cover 13. Among them, the reset member 143 can be a magnetic attraction structure, which can make the driving member 142 have a tendency to move and remain in a fixed position through magnetic attraction or magnetic repulsion, and the reset member 143 can also be an elastic member such as a spring to provide elastic force to the driving member 142 so that the driving member 142 has a tendency to move and remain in a fixed position.

In addition, the reset member 143 is arranged between the hole wall at one end of the bar hole 1423 and the side wall of the connecting column 114. For example, the reset member 143 is an elastic member such as a spring, and the two ends of the spring can be respectively abutted against the hole wall of the bar hole 1423 and the side wall of the connecting column 114; if the reset member 143 is a magnetic attraction structure, a magnet 61 can be arranged on one of the hole wall at one end of the bar hole 1423 and the side wall of the connecting column 114, and a magnet 61 or a magnetic conductive member can be arranged on the other of the hole wall of the bar hole 1423 and the side wall of the connecting column 114, so as to generate a magnetic attraction force between the hole wall of the bar hole 1423 and the side wall of the connecting column 114.

[0086] In addition, in some embodiments, a limiting hole may be provided in the first clamping member 141, and the connecting column 114 may be inserted into the limiting hole so that the first clamping member 141 is fixedly connected to the base, and only a part of the first clamping member 141 may be movably provided.

[0087] Please refer to Fig.15 and Fig.16 In some embodiments of the present application, the first clamping member 141 is provided with a clamping arm 1414 extending from the inside of the installation cavity 111 to the side opening 112, the clamping arm 1414 is clamped with the side cover 13, the driving member 142 is movably arranged on the side wall of the housing 11, and abuts against the clamping arm 1414, and the driving member 142 pushes the clamping arm 1414 from the locked position to the unlocked position when it moves toward the side of the installation cavity 111. In this embodiment, when the clamping arm 1414 is clamped with the second clamping member 131, the second clamping member 131 is located on the side of the clamping arm 1414 facing the driving member 142; the driving member 142 is configured as a pressing structure, and the clamping arm 1414 can be moved to the unlocked position in the direction away from the second clamping member 131 by pressing the driving member 142, thereby separating from the second clamping member 131, releasing the locking of the housing 11 on the side cover 13, and allowing the side cover 13 to be opened.

[0088] Optionally, two clamping arms 1414 are provided in the housing 11, respectively corresponding to the two second clamping members 131 provided on the side cover 13, and two driving members 142 for cooperating with the two clamping arms 1414 are respectively provided on the side walls on both sides of the side opening 112; the housing 11 and the side cover 13 are connected by two sets of clamping arms 1414 and the second clamping members 131, so that the connection strength and stability can be improved.

[0089] Please refer to Figure 7 In some embodiments of the present application, the mounting seat 1 includes a support plate 17, which is separated from the mounting cavity 111 and offset from the bottom opening 113. When the ink cartridge 2 is installed in the mounting cavity 111, the support plate 17 is used to support the ink cartridge 2; the first clamping member 141 is disposed between the support plate 17 and the bottom wall of the mounting cavity 111.

[0090] In this embodiment, the support plate 17 is arranged in the installation cavity 111, so that the support plate 17 can be used to support the ink cartridge 2 to improve the installation stability of the ink cartridge 2, and the support plate 17 can be used to isolate the ink cartridge 2 from the driving member 142 and the first clamping member 141, so as to avoid the driving member 142 and the first clamping member 141 from scratching the ink cartridge 2 or being interfered by the ink cartridge 2 when the driving member 142 and the first clamping member 141 are active, thereby improving the safety of use. Among them, a slot can be arranged in the cavity wall of the installation cavity 111, and the support plate 17 can be inserted into the slot to fix the support plate 17; or in the following embodiment, the support plate 17 can be supported by the connecting column 114, which is not limited here.

[0091] Please refer to Figure 5 In one embodiment of the present application, the side walls of the shell 11 located on both sides of the side opening 112 are provided with a notch on the side adjacent to the side cover 13, and when the ink cartridge 2 is installed in the installation cavity 111 and the mounting seat 1 is in an open state, part of the side wall of the ink cartridge 2 is exposed in the notch.

[0092] With this arrangement, when the ink cartridge 2 needs to be replaced or the nozzle 210 and other structures need to be cleaned or maintained, the side cover 13 can be opened so that part of the side walls of the ink cartridge 2 on both sides of the side opening 112 are exposed, so that the user can grab the ink cartridge 2. The user can grab the side wall of the ink cartridge 2 at the notch to remove the ink cartridge 2 from the installation cavity 111 or install it into the installation cavity 111. With this arrangement, the user will not touch the nozzle 210 at the bottom of the ink cartridge 2, thereby avoiding ink getting on his hands.

[0095] Please refer to Figure 6 In some embodiments of the present application, a first conductive contact 33 is provided on the surface of the conductive structure 30 facing away from the side cover 13. When the ink cartridge 2 is installed in the installation cavity 111, the first conductive contact 33 is used to contact the second conductive contact 23 on the surface of the ink cartridge 2 to electrically connect the conductive structure 30 to the ink cartridge 2.

With such a configuration, when the side cover 13 is closed on the mounting seat 1, the first conductive contact 33 and the second conductive contact 23 can be closely fitted to maintain a stable electrical connection relationship and the stability of the circuit connection.

[0098] In one embodiment of the present application, at least the supporting portion 41 of the supporting member 40 is elastic, for example, the entire supporting member 40 is elastic, or the supporting portion 41 on the supporting member 40 is elastic. In this way, it can be ensured that the first conductive contact 33 and the second conductive contact 23 are closely attached, and the supporting portion 41 is elastically deformed when subjected to the reaction force of the ink cartridge 2, thereby preventing the supporting member 40 from rigidly abutting against the conductive structure 30 and causing the conductive structure 30 to be crushed.

[0105] In some embodiments, the mounting base 1 also includes an inner shell 12, which is arranged on the inner side of the outer shell 11, and the inner shell 12 is separated by the aforementioned partition 121. The inner shell 12 forms a accommodating cavity 122 above the partition 121 to accommodate the control board 20; in addition, an opening is opened on the top of the outer shell 11, and is covered with a detachably connected upper cover 18, and a through hole 181 can be opened in the upper cover 18 to expose the power connection structure 21 set on the control board 20, so as to facilitate the electrical connection of the control board 20 with the external control circuit.

[0106] In one embodiment of the present application, the inkjet printer further includes a bottom cover 60, which is detachably mounted on the bottom of the housing 11 and can be mounted on the bottom outlet.

The water storage medium 72 is contained in the cover shell 71 and is used to store liquid. The cover shell 71 forms a storage cavity with an opening, and the water storage medium 72 is placed in the storage cavity. When the water storage structure 70 is covered at the bottom of the housing 11 with the bottom cover 60, the nozzle 210 of the ink cartridge 2 is located in the storage cavity and can contact the liquid in the storage cavity or the water storage medium 72.

[0113] Please refer to Figure 7 and Fig.14 In some embodiments of the present application, a pressing member 19 is provided on the top wall of the installation cavity 111. When the ink cartridge 2 is installed in the installation cavity 111, the pressing member 19 is used to elastically press the ink cartridge 2. The pressing member 19 may be a spring, a gas spring, a spring sheet, or the like. With such a configuration, the ink cartridge 2 can be clamped between the pressing member 19 and the bottom wall of the installation cavity 111, thereby improving the installation stability of the ink cartridge 2.
