Abstract
Description
Technical Field
[0001] This utility model relates to the field of printer accessories technology, specifically a printer maintenance box that is easy to disassemble and assemble. Background Technology
[0002] The printer maintenance compartment, also known as the waste ink tank, is a "waste ink collection station" used during printer printhead cleaning. Waste ink is generated every time the printhead is cleaned, the ink cartridge is replaced, or the printer automatically cleans itself after a long period of standby. This waste ink is absorbed by the maintenance compartment.
[0003] Once the maintenance box is full or the chip recognition fails, the printer will report an error. This can result in anything from being unable to print to the printhead becoming clogged or even the motherboard being damaged. Therefore, once the maintenance box has stored a certain amount of waste ink, it needs to be removed for maintenance.
[0004] However, the existing maintenance box disassembly and assembly structure usually uses snap-fit connections. Traditional plastic snap-fits have a "fatigue" problem and are prone to wear and breakage after repeated disassembly and assembly. Once the snap-fit breaks, it will directly affect normal use. Utility Model Content
[0005] The purpose of this invention is to provide a printer maintenance box that is easy to disassemble and assemble, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a printer maintenance box that is easy to assemble and disassemble, comprising a maintenance box body and a maintenance box mounting slot for mounting the maintenance box body. A positioning tenon is fixed to the side of the maintenance box body, and a sliding track that mates with the positioning tenon is opened on the side of the maintenance box mounting slot. The positioning tenon is inserted into the sliding track, and a first magnetic block is fixed to the end of the positioning tenon. A second magnetic block that attracts the first magnetic block is fixed to the end of the sliding track. A cover plate is provided on top of the maintenance box body. The positioning tenon provides a positioning effect during installation, ensuring that the maintenance box body is accurately aligned when pushed into the maintenance box mounting slot, preventing it from wobbling back and forth or left and right, and allowing it to withstand a certain weight. The first and second magnetic blocks attract each other after being pushed to the bottom, producing a crisp "click" sound and a slight suction force, indicating successful magnetic engagement. This prevents the module box from sliding out due to vibration during transport. The maintenance box mounting slot is integrated with the printer, providing a convenient mounting position for the printer maintenance box.
[0007] In a preferred embodiment of this invention, a recessed groove is provided on the top of the maintenance box body, and several slots are provided on the side of the recessed groove. A cover plate is disposed inside the recessed groove, and a locking block that mates with the slot is fixed on the side of the cover plate. The locking block is engaged in the slot. This allows the cover plate to be detached and installed. By using a tool to pry the cover plate, the locking block can be disengaged from the slot.
[0008] In a preferred embodiment of this invention, a detachment opening is provided between the plurality of slots. The detachment opening provides a prying point for a removal tool.
[0009] As a preferred embodiment of this invention, an external protruding pull block is fixed to the outer side of the maintenance box body. The external protruding pull block is mainly for the convenience of pulling out the maintenance box body.
[0010] As a preferred embodiment of this invention, the cover plate is provided with an observation grid. The observation grid facilitates a direct view of the internal condition of the maintenance box body.
[0011] As a preferred embodiment of this invention, the maintenance box body is provided with several sponges inside. The sponges are used to absorb waste ink.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention ensures installation alignment accuracy through the cooperation of positioning clips and sliding tracks, preventing the maintenance box from shaking; the magnetic block adsorption and fixation form a double guarantee, not only confirming the installation is in place through "audio-visual feedback", but also effectively resisting vibration during handling or equipment operation, preventing the maintenance box from sliding out on its own, and improving the safety of equipment operation.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a printer maintenance box that is easy to disassemble and assemble, including a maintenance box body 1 and a maintenance box mounting groove 2 for installing the maintenance box body 1. A positioning tenon 101 is fixed on the side of the maintenance box body 1. A sliding track 201 that cooperates with the positioning tenon 101 is opened on the side of the maintenance box mounting groove 2. The positioning tenon 101 is inserted into the sliding track 201. A first magnetic block 1011 is fixed at the end of the positioning tenon 101. A second magnetic block 2011 that attracts the first magnetic block 1011 is fixed at the end of the sliding track 201. A cover plate 3 is provided on the top of the maintenance box body 1. The positioning latch 101 is used to achieve a positioning effect during installation, ensuring that the maintenance box body 1 is accurately aligned when pushed into the maintenance box mounting slot 2, without wobbling back and forth or left and right, and can withstand a certain weight. Furthermore, by setting the first magnetic block 1011 and the second magnetic block 2011, after being pushed to the bottom, the first magnetic block 1011 and the second magnetic block 2011 attract each other, and a crisp "click" sound will be heard and a slight attraction will be felt. This is the feedback of successful magnetic engagement, preventing the module box from sliding out on its own due to vibration during transportation. The maintenance box mounting slot 2 is integrated with the printer, which is the installation position of the printer's maintenance box.
[0019] Furthermore, a recessed groove 102 is provided on the top of the maintenance box body 1, and several slots 103 are provided on the side of the recessed groove 102. The cover plate 3 is disposed inside the recessed groove 102, and a locking block 301 that cooperates with the slot 103 is fixed on the side of the cover plate 3. The locking block 301 is locked in the slot 103. This enables the cover plate 3 to be detached and installed. By using a tool to pry the cover plate 3, the locking block 301 can be disengaged from the slot 103.
[0020] Furthermore, a disassembly opening 104 is provided between the plurality of slots 103. The disassembly opening 104 is provided to provide a pry point for disassembly tools.
[0021] Furthermore, an outwardly protruding pull block 105 is fixed to the outer side of the maintenance box body 1. The outwardly protruding pull block 105 is mainly for facilitating the pulling out of the maintenance box body 1.
[0022] Furthermore, the cover plate 3 is provided with an observation grid 302. The observation grid 302 is provided to facilitate a direct view of the internal condition of the maintenance box body 1.
[0023] Furthermore, the maintenance box body 1 is equipped with several sponges 4 inside. The sponges 4 are used to absorb waste ink.
[0024] In summary, the positioning tenon 101 on the side of the maintenance box body 1 and the sliding track 201 of the maintenance box mounting groove 2 form a sliding fit. During installation, the positioning tenon 101 is pushed in along the sliding track 201, forcibly constraining the front-back and left-right displacement of the maintenance box body 1 to ensure precise alignment of the installation path. When the positioning tenon 101 is pushed to the end of the sliding track 201, the first magnetic block 1011 at the end of the tenon and the second magnetic block 2011 at the end of the track attract each other due to magnetic attraction, forming a fixed lock. At the same time, the "click" sound and slight suction feedback indicate that the installation is in place, preventing the maintenance box from sliding out on its own due to vibration. A recessed groove 102 is provided on the top of the maintenance box body 1. The cover plate 3 is embedded in the recessed groove 102. The locking block 301 on the side of the cover plate 3 and the locking groove 103 on the side of the recessed groove 102 form a locking structure to achieve the initial fixation of the cover plate 3. When it is necessary to remove the cover plate 3, the "removal opening 104" reserved on the recessed groove 102 is used as a pry point. The cover plate 3 can be pried open with a tool to disengage the locking block 301 from the locking groove 103, thus completing the removal of the cover plate 3. An "outer protruding pull block 105" is fixed on the outside of the maintenance box body 1. This pull block provides the operator with a clear point of force application. Without the need for additional tools, the maintenance box body 1 can be pulled out of the mounting groove by directly pulling the outer protruding pull block 105, simplifying the disassembly operation process.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
