Description

Technical Field

[0001] This application relates to the field of inkjet printing technology, and in particular to a cleaning device and an inkjet printer including the cleaning device. Background Technology

[0002] Inkjet printers work by spraying colored liquid ink, atomized into fine particles, onto printing paper through nozzles. After printing, some liquid ink remains on the nozzles. If not cleaned promptly, this ink can solidify and clog the nozzle orifices. Therefore, a cleaning device is needed to remove the residual ink and clean the nozzles. However, with traditional cleaning devices, some ink drips outside the device during cleaning and cannot be effectively recovered, or ink easily overflows and cannot be effectively collected. This unrecoverable ink can corrode and contaminate the inkjet printer, compromising the safety of the cleaning device. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the safety of using cleaning devices.

[0004] A cleaning device for cleaning the nozzles of an inkjet printer, the cleaning device comprising:

[0005] Mounting base; and

[0006] The recycling mechanism includes a first recycling component, a second recycling component, and a boss. The first recycling component is movably connected to the mounting base to move away from or towards the nozzle. The first recycling component has a first recycling chamber with an open opening facing the nozzle. There are multiple bosses, which protrude from the bottom wall of the first recycling chamber and are used to clean the nozzle. The second recycling component is connected to the outer side of the first recycling component and has a second recycling chamber with an open opening facing the nozzle.

[0007] In one embodiment, the volume of the second recovery chamber is less than or equal to the volume of the first recovery chamber.

[0008] In one embodiment, there are two second recycling components, which are respectively disposed on two outer surfaces extending along the length direction of the first recycling component.

[0009] In one embodiment, the height of the upper surface of the second recycling component is lower than the height of the upper surface of the first recycling component.

[0010] In one embodiment, the bottom wall of the first recovery chamber includes a first inclined surface and a first horizontal surface connected at their ends. The first horizontal surface is perpendicular to the dripping direction of the liquid on the nozzle, and the first inclined surface and the first horizontal surface intersect at an obtuse angle.

[0011] In one embodiment, the bottom wall of the second recovery chamber includes two second inclined surfaces that are connected at one end and set at an angle to each other. The second inclined surfaces are set at an acute angle to the dripping direction of the liquid on the nozzle, and the other ends of the two second inclined surfaces are respectively set close to the two ends of the first recovery component.

[0012] In one embodiment, the angle between the other end of the two second inclined surfaces and the direction of liquid dripping from the nozzle is 85° to 89°.

[0013] In one embodiment, a collection mechanism is further included, comprising a first collection component and a first vacuum pump connected to each other, and a second collection component and a second vacuum pump connected to each other. The protrusion has an adsorption hole corresponding to the nozzle. The first collection component has a first collection cavity communicating with the adsorption hole. The first vacuum pump generates a vacuum in the first collection cavity and the adsorption hole to recover the liquid on the nozzle. The second collection component has a second collection cavity communicating with the first recovery cavity. The second vacuum pump generates a vacuum in the second collection cavity and the first recovery cavity to recover the liquid in the first recovery cavity.

[0014] In one embodiment, the second recovery chamber is in communication with the second collection chamber.

[0015] An inkjet printer includes a frame, nozzles, and a cleaning device as described above, wherein both the nozzles and the mounting base are disposed on the frame.

[0016] One technical advantage of one embodiment of this application is that, given the inclusion of the second recovery component, on the one hand, ink overflowing from the first recovery chamber can be received by the second recovery chamber, preventing the ink overflowing from the first recovery chamber from contaminating and corroding other components of the inkjet printer, thereby improving the safety of the cleaning device. On the other hand, it can increase the overall coverage of the recovery mechanism, allowing ink dripping outside the first recovery chamber to be effectively received by the second recovery chamber, also preventing ink that cannot be received by the first recovery chamber from contaminating and corroding other components of the inkjet printer. This further improves the safety of the cleaning device. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] See Figure 1 , Figure 2 and Figure 3 In one embodiment of this application, the inkjet printer 10 includes a cleaning device 11, a frame 12, a nozzle 13, and a mounting assembly 14. The mounting assembly 14 and the cleaning device 11 are both mounted on the frame 12. The nozzle 13 is mounted on the mounting assembly 14 and is used to spray liquid ink for printing. The cleaning device 11 can remove residual ink on the nozzle 13 to prevent the ink from solidifying and clogging the nozzle 13, thereby achieving the purpose of cleaning the nozzle 13.

[0032] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the cleaning device 11 includes a mounting base 100 and a retrieval mechanism 200. The mounting base 100 can be fixed to the frame 12, and the retrieval mechanism 200 is movably connected to the mounting base 100, thereby allowing the mounting base 100 to move closer to or further away from the nozzle 13. The retrieval mechanism 200 includes a first retrieval member 210, a second retrieval member 220, and a boss 230. The first retrieval member 210 is movably connected to the mounting base 100 to move closer to or further away from the nozzle 13. The first retrieval member 210 has a first retrieval cavity 211, which can be formed by a recess of a predetermined depth on the surface of the first retrieval member 210 facing the nozzle 13, such that the opening of the first retrieval cavity 211 faces the nozzle 13. There are multiple bosses 230, which protrude from the bottom wall surface of the first retrieval cavity 211 and are used to clean the nozzle 13. The second recovery component 220 is connected to the outer side of the first recovery component 210. The second recovery component 220 has a second recovery cavity 221. The first recovery cavity 211 can be formed by a surface recess of the second recovery component 220 facing the nozzle 13 with a set depth. The opening of the second recovery cavity 221 is also facing the nozzle 13.

[0033] During the cleaning process of the nozzle 13 by the boss 230, the ink on the nozzle 13 may splash onto the mounting assembly 14, where ink may also be present. Therefore, by providing the first recovery chamber 211, when the suction hole 231 removes ink from the nozzle 13, the ink on the mounting assembly 14 can also drip into the first recovery chamber 211. This allows the first recovery chamber 211 to buffer the ink dripping from the mounting assembly 14, preventing it from contaminating or corroding other components of the inkjet printer 10, thus improving the safety of the cleaning device 11. Simultaneously, by providing the second recovery component 220, the total coverage of the recovery mechanism 200 can be increased, allowing ink dripping from the mounting assembly 14 into areas outside the first recovery chamber 211 to be effectively received by the second recovery chamber 221. This also prevents ink that cannot be received by the first recovery chamber 211 from contaminating or corroding other components of the inkjet printer 10. This further improves the safety of the cleaning device 11.

[0034] Given that the first recycling component 210 is movably connected to the mounting base 100, the recycling mechanism 200 has a clean position and a clearance position, see [reference]. Figure 6 and Figure 7 When the recycling mechanism 200 moves to the cleaning position, it can clean the ink. (See also...) Figure 1 and Figure 2 When the recycling mechanism 200 moves to the avoidance position, it effectively prevents interference with the nozzle 13, ensuring that the nozzle 13 can complete normal printing. (See also...) Figure 6 and Figure 7 When the inkjet printer 10 stops printing, the recycling mechanism 200 can also move to a clean position, making the entire inkjet printer 10 more compact in structure, thus facilitating the handling and storage of the inkjet printer 10. Obviously, when the inkjet printer 10 needs to print, the recycling mechanism 200 can move away from the nozzle 13 to a clearance position, avoiding interference with the normal operation of the nozzle 13.

[0035] See Figure 5 In some embodiments, the volume of the second recovery chamber 221 is less than or equal to the volume of the first recovery chamber 211. Since the ink dripping from the mounting assembly 14 will primarily be received by the first recovery chamber 211, while a small amount will be received by the second recovery chamber 221, the volume of the second recovery chamber 221 can be made less than or equal to the volume of the first recovery chamber 211. This allows for a reasonable reduction in the size and space occupied by the second recovery component 220, thereby achieving a compact design for the entire recovery mechanism 200.

[0036] See Figure 5In some embodiments, there are two second recycling elements 220, which are respectively disposed on two outer surfaces extending along the length of the first recycling element 210. Therefore, by disposing of second recycling elements 220 on both outer surfaces extending along the length of the first recycling element 210, the first recycling element 210 and the two second recycling elements 220 have a sufficiently large coverage area, thereby further increasing the total coverage of the entire recycling mechanism 200. This allows the ink to be effectively received by the first recycling element 210 and the two second recycling elements 220, effectively preventing ink from contaminating and corroding other components of the inkjet printer 10 due to the ink not being received by the recycling mechanism 200, and further improving the safety of the cleaning device 11.

[0037] See Figure 5 In some embodiments, the height of the upper surface of the second recycling member 220 is lower than the height of the upper surface of the first recycling member 210. This ensures that ink overflowing from the first recycling chamber 211 along the outer surface of the first recycling member 210 is received by the second recycling chamber 221, preventing the overflowing ink from contaminating or corroding other components of the inkjet printer 10 and improving the safety of the cleaning device 11. Simultaneously, the distance between the second recycling member 220 and the mounting assembly 14 or nozzle 13 can be reasonably increased to prevent collisions between the second recycling member 220 and the mounting assembly 14 or nozzle 13 during operation, thus avoiding damage to the mounting assembly 14 or nozzle 13 and further improving the safety of the cleaning device 11.

[0038] See Figure 4 In some embodiments, the bottom wall of the first recovery chamber 211 includes a first inclined surface 2111 and a first horizontal surface 2112. The first horizontal surface 2112 is perpendicular to the dripping direction of the liquid on the nozzle 13, that is, the first horizontal surface 2112 is perpendicular to the vertically extending straight line. The first inclined surface 2111 and the first horizontal surface 2112 intersect at an obtuse angle, so that the first inclined surface 2111 is set at an acute angle to the vertically extending straight line. Therefore, by setting the first inclined surface 2111, the first inclined surface 2111 can play a good guiding role for the ink, ensuring that the ink flows quickly into the first horizontal surface 2112, thereby ensuring that the ink enters the first recovery chamber 211 quickly.

[0039] See Figure 5In some embodiments, the bottom wall of the second recovery chamber 221 includes two second inclined surfaces 2211. One end of the two second inclined surfaces 2211 is connected to each other, and the two second inclined surfaces 2211 are arranged at an included angle, for example, the included angle can be an obtuse angle. The other ends of the two second inclined surfaces 2211 are respectively located near the two ends of the first recovery member 210. Therefore, by providing two second inclined surfaces 2211, the second inclined surfaces 2211 can play a good guiding role for ink, so that the ink overflowing from the two outer surfaces extending from the length direction of the first recovery member 210 in the first recovery chamber 211 can be quickly received by the second recovery chamber 221.

[0040] See Figure 5 In some embodiments, the angle between the other ends of the two second inclined surfaces 2211 and the dripping direction of the liquid on the nozzle 13 is 85° to 89°. This can be understood as the other ends of the second inclined surfaces 2211 approaching a plane perpendicular to the dripping direction of the liquid on the nozzle 13. This can reasonably reduce the stress concentration generated by the second recovery component 220, avoid damage to the second recovery component 220 under external impact, and thus improve the safety of the cleaning device 11. At the same time, it can also reduce the manufacturing difficulty of the second recovery component 220 to a certain extent, thereby reducing the manufacturing cost of the second recovery component 220 and the entire cleaning device 11.

[0041] See Figure 3 In some embodiments, there are multiple protrusions 230, which can protrude from the first horizontal surface 2112. These protrusions 230 are spaced apart, and their number can be equal to and correspond one-to-one with the number of nozzles 13. Adsorption holes 231 are formed on the protrusions 230. Obviously, the adsorption holes 231 correspond to the nozzles 13, and the adsorption holes 231 remove ink from the nozzles 13 through vacuum adsorption. When the cleaning device 11 is working, the recovery mechanism 200 can move relative to the mounting base 100. The recovery mechanism 200 moves closer to the nozzles 13, causing the protrusions 230 and adsorption holes 231 to move below the nozzles 13. Of course, the protrusions 230 and nozzles 13 can maintain a relatively small distance. Then, a vacuum is generated within the adsorption holes 231. Under the action of vacuum adsorption, the ink remaining in the nozzles 13 is adsorbed into the adsorption holes 231, thus achieving the cleaning of ink by the protrusions 230.

[0042] If the recycling mechanism 200 cleans the ink on the nozzle 13 by scraping, it will cause the recycling mechanism 200 to come into direct contact with the nozzle 13, generating a large scraping force that could damage the nozzle 13 and affect the safety of the cleaning device 11. Furthermore, the scraping method has limited ink removal capacity, leaving a certain amount of ink on the nozzle 13, thus affecting the cleaning effect of the cleaning device 11. Additionally, the recycling mechanism 200 would need to repeatedly scrape the nozzle 13, consuming a significant amount of time and thus reducing the efficiency of the cleaning device 11.

[0043] Regarding the cleaning device 11 in the above embodiments, since the suction hole 231 removes ink from the nozzle 13 through vacuum suction, this effectively avoids the scraping force generated by the contact and relative movement between the recovery mechanism 200 and the nozzle 13, thereby preventing damage to the nozzle 13 by the recovery mechanism 200 and improving the safety of the cleaning device 11. Furthermore, the vacuum suction can completely remove ink from the nozzle 13, preventing any residual ink from remaining on the nozzle 13, thus improving the cleaning effect of the cleaning device 11. Moreover, the vacuum suction can remove all residual ink from the nozzle 13 in a short time, thereby reducing the ink removal time and improving the working efficiency of the cleaning device 11.

[0044] In some embodiments, the cleaning device 11 further includes a collection mechanism 300, which includes a first collection component 310 and a first vacuum pump. The first collection component 310 and the first vacuum pump are interconnected. The first collection component 310 has a first collection cavity, which is connected to the adsorption hole 231. When the first vacuum pump generates a vacuum in the first collection cavity, a vacuum is generated in the adsorption hole 231 to adsorb ink, thereby achieving the cleaning of ink by the boss 230. Under the action of vacuum adsorption force, the ink remaining in the nozzle 13 will be adsorbed into the adsorption hole 231, and the ink entering the adsorption hole 231 will flow into the first collection cavity, so that the first collection cavity can store the ink.

[0045] See Figure 3 and Figure 5In some embodiments, the flow collection mechanism 300 further includes a second flow collection component 320 and a second vacuum pump. The second flow collection component 320 and the second vacuum pump are interconnected. The second flow collection component 320 has a second flow collection chamber, which is connected to the first recovery chamber 211. When the second vacuum pump generates a vacuum in the second flow collection chamber, it will also generate a vacuum in the first recovery chamber 211. This allows the ink on the mounting component 14 to enter the first recovery chamber 211 through vacuum adsorption. Therefore, when the second vacuum pump is working, it can generate a vacuum in the second flow collection chamber and the first recovery chamber 211, thereby allowing the ink in the first recovery chamber 211 to flow into the second flow collection chamber, enabling the second flow collection chamber to store the ink.

[0046] In some embodiments, the second recovery chamber 221 is connected to the second collection chamber, that is, the second recovery chamber 221 and the first recovery chamber 211 are both connected to the second collection chamber. Therefore, when the second vacuum pump is working, it can generate a vacuum in the second collection chamber and the second recovery chamber 221, so that the ink in the second recovery chamber 221 will flow into the second collection chamber, so that the second collection chamber can play a storage role for the ink.

[0047] In some embodiments, the first current collection component 310 can be disposed on the first recycling component 210, so that the first current collection component 310 can move with the first recycling component 210, while the second current collection component 320 is disposed on the mounting base 100. In this way, the first current collection component 310 and the second current collection component 320 can be reasonably arranged in space to ensure the effective operation of the various functions of the current collection mechanism 300.

[0048] In some embodiments, the vacuum degree of the first recovery chamber 211 is less than or equal to the vacuum degree of the adsorption orifice 231. For example, the vacuum degree of the first recovery chamber 211 can be less than the vacuum degree of the adsorption orifice 231. This results in a relatively high vacuum degree of the adsorption orifice 231 and a relatively low vacuum degree of the first recovery chamber 211. Because there is a large adsorption force between the ink remaining on the nozzle 13 and the nozzle 13, the vacuum degree of the adsorption orifice 231 is relatively high, thereby improving the removal effect of ink on the nozzle 13 and ultimately improving the cleaning effect of the cleaning device 11. On the other hand, there is a relatively small adsorption force between the ink remaining on the mounting assembly 14 and the mounting assembly 14, so the first recovery chamber 211 can recover the ink on the mounting assembly 14 with a small vacuum adsorption force, thereby achieving the effect of saving energy.

[0049] See Figure 1 and Figure 3In some embodiments, the cleaning device 11 further includes a rotary table 410 and a driver 420, which can be a servo motor or a stepper motor, etc. The driver 420 is mounted on the mounting base 100, and the rotary table 410 is rotatably connected to the mounting base 100, so that the rotary table 410 can rotate about a rotating axis extending along the dripping direction of ink on the nozzle 13. In fact, the dripping of ink on the nozzle 13 is in a vertical direction, so the rotary table 410 rotates about the vertically extending rotating axis. The driver 420 is used to drive the mounting base 100 to rotate relative to the rotary table 410. The recycling mechanism 200 can be fixedly mounted on the rotary table 410, so the recycling mechanism 200 can rotate synchronously with the rotary table 410, so that the recycling mechanism 200 moves between a cleaning position and a avoidance position. Along the rotation direction of the recycling mechanism 200, the cleaning position and the avoidance position can be spaced at a certain angle, for example, the cleaning position and the avoidance position can be spaced at about 95°.

[0050] See Figure 1 In some embodiments, the cleaning device 11 may further include a storage container 500, which may be fixed on the frame 12 of the inkjet printer 10. The first and second flow collectors are both connected to the storage chamber of the storage container 500, so that the ink buffered in the first and second flow collectors can flow into the storage container 500. The ink stored in the storage container 500 can be recycled.

[0051] See Figure 3 , Figure 4 and Figure 5 In some embodiments, a plurality of connecting holes 212 are recessed on the first horizontal surface 2112 of the first recovery chamber 211. These connecting holes 212 are spaced apart, and a boss 230 may be provided between two adjacent connecting holes 212. The connecting holes 212 communicate with the first recovery chamber 211 and the second collection chamber. That is, the ink on the first recovery chamber 211 enters the second collection chamber through the connecting holes 212. By providing multiple connecting holes 212, when the second vacuum pump is working, the ink in the first recovery chamber 211 can quickly enter the second collection chamber.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
