Technical Field

[0001] The present application relates to the technical field of printers, and particularly relates to a print head mounting assembly and a printer. Background Art

[0002] A printer is one of the output devices of a computer, used to print the processing results of the computer on relevant media. A print head is a printer component that performs coloring and transfer on the relevant media.

[0003] Currently, installing a print head requires exposing the internal movement components of the printer, and the installation process is complex. Summary of the Invention

[0004] The present application provides a print head mounting assembly and a printer.

[0005] Specifically, the present application is implemented through the following technical solutions:

[0006] One aspect of the present application provides a print head mounting assembly for mounting a print head on a printer. The print head mounting assembly includes:

[0007] A bracket;

[0008] A base provided with a mounting groove for mounting the print head. The base includes a rotating end and a free end. The rotating end is rotatably connected to the bracket, and the free end is provided with a mounting opening communicating with the mounting groove;

[0009] The base has a closed state and an open state; in the open state, the base is inclined relative to the bracket, and the free end is away from the bracket; in the closed state, the base is arranged side by side with the bracket.

[0010] Further, the print head mounting assembly further includes a rotating device. The rotating device includes a rotating shaft and an elastic member. The rotating shaft is arranged on the bracket and passes through the rotating end. The elastic member is mounted on the rotating shaft, and the elastic member is rotatably connected to the rotating shaft and the bracket. The elastic member is used to provide an elastic force for the base to rotate relative to the bracket.

[0011] The cooperation of the rotating shaft and the elastic member provides a force for the base to rotate relative to the bracket, enabling the base to be lifted, which is convenient for the user to install the print head.

[0012] Further, the base is provided with a limiting tongue;

[0013] The elastic member is used to provide an elastic force for the base to rotate in a direction away from the bracket, and the limiting tongue is used to keep the base in the closed state; or

[0014] The elastic member is used to provide an elastic force for the base to rotate in the direction close to the bracket, and the limiting tongue is used to hold the base in the open state.

[0015] Different settings of the elastic member make the base tend to move in different rotational directions relative to the bracket, and the limiting tongue holds the base in a stable state, preventing the base from being unable to switch states due to the elastic force of the elastic member.

[0016] Further, when the elastic member is used to provide an elastic force for the base to rotate away from the bracket, and the limiting tongue is used to hold the base in the closed state, the print head mounting assembly further includes a locking member located on one side close to the free end and connected to the bracket, and the locking member is provided with a clamping portion that is in limiting cooperation with the limiting tongue.

[0017] Through the limiting cooperation between the clamping portion on the locking member and the limiting tongue, the base is held in the closed state, and after the locking member disengages from the limiting tongue, the base has a tendency to move away from the bracket, and the base can switch from the closed state to the open state.

[0018] Further, the locking member is provided with a pushing portion, and when the base is in the closed state, the pushing portion is located between the bracket and the base and abuts against the base; and / or

[0019] The locking member is provided with a limiting projection, and the base is provided with a limiting groove that cooperates with the limiting projection; and / or

[0020] One side of the locking member away from the base is provided with an abutting plane, and the abutting plane is inclined relative to the locking member.

[0021] The pushing portion pushes the base away from the bracket during the process of the base switching from the closed state to the open state, making the state switching of the base faster and more convenient. The cooperation between the limiting projection on the locking member and the limiting groove on the base can not only limit the base, but also push the base to move when the locking member disengages from the base. The abutting plane can limit the rotation range of the locking member and prevent the locking member from colliding and rubbing against the printer.

[0022] Further, the print head mounting assembly further includes a rotating device, the rotating device includes a pin shaft and a reset member, the pin shaft is arranged on the bracket and passes through the locking member, the reset member is mounted on the pin shaft, and the reset member is used to provide an elastic force for the locking member to rotate away from the bracket.

[0023] The cooperation between the pin shaft and the reset member provides a force for the locking member to rotate relative to the bracket, so that the locking member disengages from or connects to the base to switch the state of the base.

[0024] Further, a guide rail is provided on the inner wall of the installation groove; and / or

[0025] The installation groove is provided with a partition member for partitioning the installation groove into a plurality of installation stations.

[0026] By providing the guide rail, it is convenient for the print head to slide into from the installation opening, improving the convenience of installing the print head. The partition member divides the installation groove into a plurality of installation stations to adapt to printers with different numbers of print heads.

[0027] One aspect of the present application provides a printer, including a housing and the print head mounting assembly described in any one of the above.

[0028] Further, the printer is provided with a receiving bin for receiving the print head mounting assembly, and the housing is provided with an opening part communicating with the receiving bin at a position corresponding to the print head mounting assembly;

Users do not need to open the paper output tray, the paper jam clearing door or the entire scanning assembly of the printer, avoiding excessive exposure of the internal movement components of the printer and causing accidental damage, and improving the aesthetic degree of the print head mounting assembly. The bin door can protect the print head mounting assembly inside the receiving bin and the internal movement and parts of the printer to a certain extent.

[0031] Further, at least one limiting part for limiting and cooperating with the print head mounting assembly is provided in the receiving bin.

[0032] The position where the locking part and / or the base are opened is restricted by the limiting part to prevent the locking part and / or the base from colliding with other internal components of the printer and causing damage after being opened.

[0047] The printer of the embodiments of this application includes a housing and a printhead mounting assembly.

[0048] The printhead mounting assembly and the printer of this application will be described in detail below with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0049] Figure 1The figure shows a schematic cross-sectional view of an embodiment of the printer 1 of the present application. The print head mounting assembly 10 is used to mount the print head 20 on the printer 1. The printer 1 includes, but is not limited to, an inkjet printer. The print head 20, also known as a print head nozzle, is a component of the printer 1 that colors and transfers the results of computer processing onto a relevant medium. It is generally installed inside the printer 1 and can move within a certain range. The print head 20 performs printing work on the medium through nozzles. Depending on the model of the printer 1, the number of print heads 20 is not limited and is at least one. The printer 1 of the embodiment of the present application includes a print head mounting assembly 10 and a housing 11. The housing 11 includes the overall housing of the printer 1 and a support structure extending into the printer 1. The print head mounting assembly 10 is installed inside the housing 11.

[0050] In some embodiments, the printer 1 is provided with a receiving chamber 12 for accommodating the print head mounting assembly 10. In the related art, when a user installs a print head, they need to open the paper output tray and the paper jam clearing door of the printer or the entire scanning assembly. At this time, the internal movement components of the printer may be exposed, making the appearance messy and unaesthetic. The receiving chamber 12 of the embodiment of the present application allows the user to install or remove the print head 20 without opening the paper output tray and the paper jam clearing door of the printer 1 or the entire scanning assembly. The print head 20 can be installed through the receiving chamber 12, avoiding excessive exposure of the internal movement components of the printer 1 and causing accidental damage, and improving the aesthetic degree of the print head mounting assembly 10.

[0051] In some embodiments, the receiving chamber 12 is a space with a certain volume surrounded by the housing 11. In other embodiments, the receiving chamber 12 is a reserved space inside the printer 1. Preferably, the receiving chamber 12 is provided on one side of the printer 1 close to the edge. During the period when the printer 1 is not in use, the print head mounting assembly 10 is housed on one side of the printer 1, making the arrangement of the internal parts of the printer 1 neat and aesthetic.

[0052] In some embodiments, the housing 11 is provided with an opening 13 communicating with the receiving chamber 12 at a position corresponding to the print head mounting assembly 10, facilitating the user to install the print head 20 or replace and repair the damaged print head mounting assembly 10 through the opening 13. The size and shape of the opening 13 can be reasonably adjusted according to the size of the print head 20 and the print head mounting assembly, so that the print head 20 or the print head mounting assembly does not collide with the opening 13 during the process of installing the print head 20 or replacing and repairing the damaged print head mounting assembly 10. In some embodiments, the opening 13 is provided on the side wall surface of the printer 1 to save the user operation space on the front of the printer 1. In other embodiments, the opening 13 is provided on the upper wall surface of the printer 1 to adapt to the user's operation habits and improve the visibility of the user operation.

[0053] Continue to refer toFigure 1 , in some embodiments, the printer 1 further includes a door 14 disposed at the opening 13, which can protect the print head mounting assembly 10 inside the receiving chamber 12 and the internal movement parts of the printer 1 to a certain extent. In some embodiments, the door 14 is movably disposed at the opening 13. When the door 14 is closed, the door 14 completely covers the opening 13; when the door 14 is open, at least a part of the opening 13 is exposed so that the user can perform operations. In some embodiments, one side of the door 14 is rotatably connected to the housing 11 on one side of the opening 13. Further, the door 14 is provided with a buckle, and correspondingly, the housing 11 is provided with a buckle position that cooperates with the buckle, so as to prevent the door 14 from accidentally opening without external force when the door 14 is closed and covers the housing 11. In some embodiments, the door 14 can perform telescopic movement in the length direction or the width direction of the opening 13, and the user can push or pull one end of the door 14 to open or close the door 14. Further, the door 14 is provided with a spring, and the spring provides an elastic force for the door 14 to move relative to the housing 11. In some embodiments, the door 14 is designed to be transparent to improve the visibility of the user.

[0054] The print head mounting assembly 10 of the embodiment of the present application includes a bracket 100 and a base 200 for mounting the print head 20, and the base 200 is disposed on the bracket 100. In some embodiments, the bracket 100 can move inside the printer 1. Further, the printer 1 is provided with a track (not shown in the figure) that cooperates with the bracket 100. The track is parallel to the length direction of the printer 1 in space and perpendicular to the paper feeding direction, and the track is disposed above the paper. During the movement of the bracket 100 on the track, the base 200 and the print head 20 are driven to move so that the nozzles at the bottom of the print head 20 face the paper to spray ink.

[0055] In some embodiments, the base 200 includes a rotating end 210 and a free end 220. The rotating end 210 is rotatably connected to the bracket 100, so that the base 200 can rotate relative to the bracket 100 within a certain angle range. When the user installs the print head 20, the included angle between the base 200 and the bracket 100 can be changed, increasing the viewing range of the user for the print head mounting assembly 10 and improving the convenience of installing the print head 20. In the related art, the base is fixed to the bracket. After the user opens the cover plate on the base and then installs the print head, the visibility of the user is low, the operation difficulty is high, the success rate of the operation is low, which affects the user experience. Compared with the fixed base solution, the base 200 of the embodiment of the present application can rotate relative to the bracket 100, the visibility of the user is higher, the operation difficulty is reduced, the success rate of the operation is improved, bringing a better use experience to the user. In some embodiments, the rotating end 210 and the free end 220 are oppositely arranged.

[0056] The base 200 includes a closed state and an open state. In some embodiments, the switching between the closed state and the open state requires manual operation by the user, which improves the accuracy of operation and avoids misjudgment of automatic control. In other embodiments, the switching between the closed state and the open state can be automatically switched by the sensing device and the controller provided in the printer 1 for the state of the base 200 or by other means, without the need for manual operation by the user, thus enhancing the user experience. Further, the sensing device is disposed at the opening 13 to sense the opening and closing of the chamber door 14.

[0057] Continuing to refer to Figure 1 , in the closed state, the base 200 is arranged side by side with the bracket 100, and the free end 220 of the base 200 is close to the bracket 100. In some embodiments, when the base 200 is in the closed state, the included angle between the base 200 and the bracket 100 is 0 degrees. After the print head 20 is installed, when the base 200 switches from the open state to the closed state and the print head 20 moves with the bracket 100, the print head 20 is perpendicular to the paper to ensure the printing effect. In some embodiments, the base 200 has a limiting structure that cooperates with the bracket 100 and / or the housing 11, and the user can open the base 200 by an external force to prevent the base 200 from shifting during the closed state or even during the printing process, which may affect the printing effect.

[0058] Figure 2 As shown in Figure 1 Figure 11 is a side cross-sectional view of the printer 1 shown in Figure 10 with the base 200 of the print head mounting assembly 10 in the closed state. Figure 3 As shown in Figure 1 Figure 15 is a side cross-sectional view of the printer 1 shown in Figure 14 with the base 200 of the print head mounting assembly 10 in the open state. Referring to Figure 3 , in the open state, the base 200 is inclined relative to the bracket 100, and the free end 220 of the base 200 is away from the bracket 100. In some embodiments, the base 200 and / or the housing 11 are provided with a limiting structure such that the included angle between the base 200 and the bracket 100 in the open state is a certain fixed angle and cannot be adjusted by the user. Preferably, the included angle between the base 200 and the bracket 100 is 50 degrees to achieve the best user experience and visibility. In other embodiments, the base 200 is provided with an angle adjustment structure, and the user can adjust the included angle between the base 200 and the bracket 100 within a certain angle range. The user can reasonably adjust the opening angle according to the distance, standing position, height, and viewing angle relative to the printer 1 to achieve personalized adaptation of the lifting angle of the base 200 for different users. Preferably, the angle adjustment structure is a stepless adjustment structure, and the user can arbitrarily adjust the included angle between the base 200 and the bracket 100 within a certain angle range. In some embodiments, the stepless adjustment structure is a gear adjustment assembly and / or a screw adjustment assembly.

[0059] Figure 4 The figure shows a perspective structural view of a base 200 of a printer installation component 10 according to the present application. In some embodiments, the base 200 is provided with an installation groove 230 for installing a print head 20. In some embodiments, the number of the installation grooves 230 is one. In some embodiments, the installation groove 230 is provided with a partition member 233, and the partition member 233 divides the installation groove 230 into a plurality of installation stations 234. Preferably, the number of the installation stations 234 is two, and they are arranged side by side, and are respectively used for installing a black-and-white print head and a color print head.

[0060] In some embodiments, the free end 220 is provided with an installation opening 231 communicating with the installation groove 230. The installation opening 231 is an opening of the installation groove 230, and the print head 20 enters the installation groove 230 from the installation opening 231. In some embodiments, the installation opening 231 is of an open design. When the base 200 is in an open state, the installation opening 231 is not covered by a cover plate, and the user can directly install the print head 20 into the installation groove 230 from the installation opening 231, which improves the convenience of user operation. In other embodiments, the installation opening 231 is provided with a movable cover plate to further improve the stability of the installation of the print head 20. It can be understood that, in combination with Figure 2 and Figure 3 As shown, when the base 200 is in a closed state and the door 14 is opened, the print head is shielded and hidden inside by the base 200, which has better aesthetics. When the base 200 is in an open state, the base 200 is inclined relative to the bracket 100, and the free end 220 of the base 200 is away from the bracket 100, so that the installation opening 231 is away from the bracket 100, which is convenient for the user to install the print head 20.

[0061] In some embodiments, the upper wall surface of the base 200 is provided with a groove 270 to facilitate the user to take the print head 20 installed in the installation groove 230. The number of the grooves 270 can be adjusted according to the number of the print heads 20.

[0062] Figure 5 As shown in Figure 3 a schematic cross-sectional view of the disassembled base 200 of the printer 1 and the print head 20 shown. Refer to Figure 4 and Figure 5, in some embodiments, a guide rail 232 is provided on the inner wall of the mounting groove 230, enabling the print head 20 to slide from the mounting opening 231 to the mounting groove 230 via the guide rail 232, thereby improving the convenience of the user during the installation process. Generally, a protrusion 21 is provided on the outside of the print head 20, and the protrusions 21 are symmetrically arranged on both sides of the print head 20 facing the guide rail 232. Through the cooperation of the guide rail 232 and the protrusion 21, when the base 200 is in the open state, the print head 20 can slide into the mounting groove 230 under the action of gravity with relatively small resistance. In some embodiments, a stop structure is provided at a position of the guide rail 232 close to the rotation end 210, so that the print head 20 stops sliding when it slides to the stop structure, and the print head 20 is then installed at the designated position.

[0063] Figure 6 The side view of an embodiment of the printer mounting assembly 10 of the present application is shown. In some embodiments, the print head mounting assembly 10 further includes a rotating device 300 for connecting the bracket 100 and the base 200. The rotating device 300 is provided at the rotation end 210 of the base 200, enabling the base 200 to rotate relative to the bracket 100 and enabling the base 200 to have an open state and a closed state. In some embodiments, the rotating device 300 includes a rotating shaft 310 and an elastic member 320. Further, at least a part of the rotating shaft 310 protrudes from the base 200. In some embodiments, the rotating shaft 310 is provided on the bracket 100 and passes through the rotation end 210 of the base 200, and the rotating shaft 310 can be provided on opposite sides of the bracket 100 facing the base 200. In some embodiments, the rotating shaft 310 is provided at the rotation end 210 of the base 200 and passes through the bracket 100, and the rotating shaft 310 can be provided on opposite sides of the base 200 facing the bracket 100. In other embodiments, the rotating shaft 310 passes through the bracket 100 and the base 200. Preferably, the number of both the rotating shaft 310 and the elastic member 320 is two.

[0064] In some embodiments, the elastic member 320 is mounted on the rotating shaft 310, and the elastic member 320 is rotatably connected between the rotating shaft 310 and the bracket 100. The elastic member 320 is used to provide an elastic force for the base 200 to rotate relative to the bracket 100. The elastic member 320 is an element that deforms under an external force and returns to its original state after the external force is removed, including but not limited to a torsion spring. In some embodiments, the elastic member 320 includes a body portion 321 and a first torsion arm 322 and a second torsion arm 323 respectively provided on both sides of the body portion 321. The body portion 321 is mounted on the rotating shaft 310, the first torsion arm 322 abuts against the base 200, and the second torsion arm 323 abuts against the bracket 100.

[0065] In some embodiments, the elastic member 320 is configured to provide an elastic force for the base 200 to rotate in the direction approaching the bracket 100. That is to say, the elastic member 320 has an elastic force that causes the free end 220 of the base 200 to approach the bracket 100. In the case where no external force is applied to the base 200, the base 200 is in a closed state; only after an external force is applied to the base 200, the elastic member 320 is compressed and deformed, and the base 200 switches from the closed state to the open state. At this time, the user needs to manually lift the base 200 upward by a certain angle. After installing the print head 20, release the base 200, and the base 200 returns to the closed state under the action of the restoring force generated by the deformation of the elastic member 320. Further, the base 200 is provided with a limiting tongue 240, and the printer 1 is provided with a limiting element that is in limiting cooperation with the limiting tongue 240 to stably hold the base 200 in the open state and prevent the base 200 from continuing to move in the direction approaching the bracket 100, facilitating the user to install the print head 20.

[0066] In other embodiments, the elastic member 320 is configured to provide an elastic force for the base 200 to rotate in the direction away from the bracket 100. That is to say, the elastic member 320 has an elastic force that causes the free end 220 of the base 200 to move away from the bracket 100. In the case where no external force is applied to the base 200, the base 200 is in an open state; only after an external force is applied to the base 200, the elastic member 320 is compressed and deformed, and the base 200 switches from the open state to the closed state. Further, the base 200 is provided with a limiting tongue 240, and the printer 1 is provided with a limiting element that is in limiting cooperation with the limiting tongue 240 to stably hold the base 200 in the closed state and prevent the base 200 from always being in the open state and unable to perform printing work.

[0067] Reference Figure 4 , based on the above embodiments, the limiting tongue 240 is disposed in the installation groove 230. In some embodiments, the limiting tongue 240 is disposed between the partition member 233 and the base 200. In some embodiments, the limiting tongue 240 protrudes from the edge of the base 200. Further, the limiting tongue 240 protrudes upward by a certain distance and is inclined toward the base 200 at the end. Preferably, the limiting tongue 240 is made of a material with a certain elasticity to prevent it from breaking.

[0068] Reference Figure 5, in some embodiments, the printhead mounting assembly 10 further includes a locking member 400, and the locking member 400 is located on a side close to the free end 220 of the base 200. One end of the locking member 400 is connected to the bracket 100, and the other end is in limit fit with the base 200 to limit the state of the base 200. In some embodiments, the locking member 400 is made of a material with certain elasticity, one end of which is fixedly connected to the bracket 100, and the other end is in limit fit with the base 200. In some embodiments, the locking member 400 sequentially includes a clamping portion 410, a pushing portion 420, and a rotation limiting portion 430 from top to bottom. Among them, the clamping portion 410 is in limit fit with the limit tongue 240 to stably hold the base 200 in the closed state. Further, a clamping protrusion 411 is provided at the end of the clamping portion 410, and the clamping protrusion 411 protrudes outward, and the protruding direction of the clamping protrusion 411 is opposite to the protruding direction of the limit tongue 240 to achieve a better limit fit effect, so that the base 200 is in a stable state, and to a certain extent, reduce the possibility of accidental opening of the base 200. In some embodiments, anti-slip patterns are provided at the end of the clamping portion 410 to facilitate the user to manually operate the locking member 400.

[0069] Figure 7 is shown as Figure 6 a schematic cross-sectional view of the printhead mounting assembly 10 shown in. Refer to Figure 6 and Figure 7, the pushing portion 420 extends in the direction towards the base 200. During the process of the base 200 switching from the closed state to the open state, the pushing portion 420 pushes the base 200 in the direction away from the bracket 100, and during the process of the base 200 switching from the open state to the closed state, the base 200 pushes the pushing portion 420 in the direction towards the bracket 100, making the state switching of the base 200 and the locking member 400 faster and more convenient. In addition, during the process of the base 200 switching from the open state to the closed state, the pushing portion 420 has a limiting effect on the base 200, preventing the base 200 from continuing to rotate in the same direction after the included angle between it and the bracket 100 reaches 0 degrees, and ensuring the correct installation position of the print head 20. In some embodiments, the base 200 includes an abutting portion 260 located at the lower end of the base 200 for abutting and cooperating with the pushing portion 420. When the pushing portion 420 moves upward, the pushing portion 420 pushes the abutting portion 260 upward, and limits the rotation angle of the abutting portion 260 when the abutting portion 260 rotates downward. During the process of the base 200 moving towards the bracket 100, the abutting portion 260 abuts against the pushing portion 420 and pushes the pushing portion 420 downward, driving the locking member 400 to rotate, so that the locking member 400 is in limit cooperation with the base 200. In some embodiments, the pushing portion 420 includes a plurality of push rods. Further, when the number of print heads 20 is two, there is a push rod between the print heads 20, which can further limit the two print heads 20 at the specified installation positions, preventing the two print heads 20 from shifting due to the shaking of the printer 1 or other reasons and affecting the printing effect.

[0070] The rotation limiting portion 430 is rotatably connected to the bracket 100. In some embodiments, the print head mounting assembly 10 further includes a rotating device 500 provided on the rotation limiting portion 430, enabling the locking member 400 to rotate relative to the bracket 100 and enabling the locking member 400 to have a locked state and an unlocked state. When the locking member 400 is in the locked state, the locking member 400 is connected to the base 200, and the base 200 switches from the open state to the closed state. When the locking member 400 is in the unlocked state, the locking member 400 is disengaged from the base 200, and the base 200 switches from the closed state to the open state. In some embodiments, the rotating device 500 includes a pin shaft 510 and a reset member 520. In some embodiments, the pin shaft 510 is provided on the bracket 100 and passes through the locking member 400. In some embodiments, the pin shaft 510 is provided on the locking member 400 and passes through the bracket 100. In other embodiments, the pin shaft 510 passes through the bracket 100 and the locking member 400.

[0071] Reference Figure 6, in some embodiments, the reset member 520 is installed on the pin shaft 510, and the reset member 520 is used to provide an elastic force for the locking member 400 to rotate away from the bracket 100. The reset member 520 is a component that deforms under an external force and returns to its original state after the external force is removed, including but not limited to a torsion spring. In some embodiments, the reset member 520 is used to provide an elastic force for the locking member 400 to rotate towards the base 200. That is to say, the reset member 520 has an elastic force to make the engaging portion 410 approach the base 200. When no external force is applied to the locking member 400, the locking member 400 is in a locked state; only when an external force is applied to the locking member 400, the reset member 520 compresses and deforms, and the locking member 400 switches from the locked state to the unlocked state. In some other embodiments, the reset member 520 is used to provide an elastic force for the locking member 400 to rotate away from the base 200. That is to say, the reset member 520 has an elastic force to make the engaging portion 410 away from the base 200. When no external force is applied to the locking member 400, the locking member 400 is in a locked and unlocked state, and the base 200 is in a closed state; only when an external force is applied to the locking member 400, the reset member 520 compresses and deforms, and the locking member 400 switches from the unlocked state to the locked state, and the base 200 switches to the open state.

[0072] In some embodiments, the locking member 400 is provided with a limiting protrusion 412, and the base 200 is provided with a limiting groove 250 that cooperates with the limiting protrusion 412. When the locking member 400 is in the locked state, the limiting protrusion 412 is located in the limiting groove 250 to limit the rotation or displacement in other directions of the base 200; when the locking member 400 is in the unlocked state, the limiting protrusion 412 abuts against the inner wall of the limiting groove 250 and moves in a direction away from the limiting groove 250. When the limiting protrusion 412 moves to the arc-shaped edge at the opening of the limiting groove 250, the limiting protrusion 412 continues to move and pushes the limiting groove 250 upwards to push the base 200 in a direction away from the locking member 400, making the rotation of the base 200 smoother and faster.

[0073] Reference Figure 3 and Figure 6, in some embodiments, an abutting plane 431 is provided on a side of the locking member 400 away from the base 200. During the process of the locking member 400 switching from the self-locking state to the unlocking state, when the locking member 400 rotates to a position where the abutting plane 431 abuts against the housing 11 or the bottom surface of the printer 1, the locking member 400 cannot continue to rotate in the same direction, thereby restricting the rotation range of the locking member 400, preventing the locking member 400 from rotating infinitely away from the bracket 100 and out of the user's field of view, and avoiding damage caused by the collision between the locking member 400 and the housing 11 or the bottom surface of the printer 1. In some embodiments, the abutting plane 431 is inclined with respect to the locking member 400. Preferably, the angle between the abutting plane 431 and the locking member 400 is greater than 0 degrees and less than 90 degrees. Further, the abutting plane 431 and the locking member 400 are connected by an arc transition to prevent abrasion caused by friction between the connection portion of the abutting plane 431 and the locking member 400 and the printer 1 during rotation, and to improve the service life of the locking member 400.

[0074] Reference Figure 3 and Figure 5 , in some embodiments, a limiting portion for limiting and cooperating with the print head mounting assembly 10 is provided in the receiving bin 12, and the number of the limiting portions is at least one. In some embodiments, the limiting portion includes a first limiting portion 15, which is in limiting cooperation with the base 200. When the base 200 is in the open state and has a tendency to move away from the bracket 100 under the elastic force generated by the elastic member 320, the base 200 may collide with the housing 11 or the door 14 of the printer 1, causing damage; at the same time, the angle of the base 200 cannot be maintained within a range with a better user experience, affecting the user's operation view and use experience. Further, the first limiting portion 15 is located below the opening 13 and protrudes downward, and can limit the continuous rotation of the base 200. Preferably, a buffer member, such as a rubber pad, can be provided at the portion where the first limiting portion 15 abuts against the base 200, so as to prevent the base 200 from being lifted and colliding with the first limiting portion 15, causing damage to the base 200 and / or the first limiting portion 15, and to extend the service life of the base 200. Preferably, the first limiting portion 15 keeps the angle between the base 200 and the bracket 100 at 50 degrees when the base 200 is in the open state.

[0075] In some embodiments, the limiting portion includes a second limiting portion 16 and a third limiting portion 17, both of which are in limiting cooperation with the locking member 400. When the locking member 400 is in the unlocked state and has a tendency to move away from the bracket 100 under the action of the elastic force generated by the reset member 520, the locking member 400 may collide with the housing 11 of the printer 1, causing damage. At the same time, if the locking member 400 rotates without limitation, it will abut against the bottom surface inside the printer 1. When the user needs to manually switch it from the unlocked state to the locked state, the locking member 400 may not be within the user's field of vision, resulting in a blind spot in the user's operation. Therefore, by setting the second limiting portion 16 and the third limiting portion 17, the rotation range of the locking member 400 can be restricted to ensure that it is located inside the receiving bin 12, improving the convenience of user operation. Further, the second limiting portion 16 and the third limiting portion 17 are located on the housing 11 inside the receiving bin 12. Both the second limiting portion 16 and the third limiting portion 17 are in limiting cooperation with the engaging portion 410. The second limiting portion 16 is located above the third limiting portion 17, and the third limiting portion 17 extends a certain distance in the direction of the locking member 400. Preferably, buffer members, such as rubber pads, can be provided at the portions where the second limiting portion 16 abuts against the locking member 400 and the portions where the third limiting portion 17 abuts against the locking member 400, so as to prevent the locking member 400 from rotating and colliding with the first limiting portion 15, causing damage to one or several of the locking member 400, the second limiting portion 16, and the third limiting portion 17, and prolonging the service life of the locking member 400.

[0076] The usage process of the print head mounting assembly 10 according to an embodiment of the present application is as follows: As Figure 1 shown, the bin door 14 is closed, and the base 200 is in the closed state. When it is necessary to install or replace the print head 20, first open the bin door 14, as Figure 2 shown. At this time, the base 200 is still in the closed state. Then operate the locking member 400 to make the base 200 rotate and turn outwards, as Figure 3 shown. At this time, the base 200 switches to the open state. The user can remove the original print head 20 and install a new print head 20 or directly install the print head 20. After the print head 20 is installed in the installation slot 230, operate the locking member 400 or the base 200 to make the base 200 become the closed state, as Figure 2 shown. Finally, close the bin door 14, as Figure 1 shown, to complete the installation of the print head 20. The entire installation process of the print head 20 is simple, fast, highly operable, and the interaction between the user and the printer 1 is friendly, providing a good user experience.

[0077] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the scope of protection of the present application.
