Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing technology, in particular to an ink container. BACKGROUND

[0002] A printing device can eject ink on a printing medium to form an image on the printing medium. The printing device includes an ink supply unit and a print head, and the ink supply unit supplies ink to the print head. An ink inlet is arranged on the ink supply unit, and when a user finds that the ink in the ink supply unit is insufficient, the ink supply unit can be supplemented with ink through the docking of the ink container and the ink inlet.

[0003] After supplying a part of the ink, the ink container is prone to form a negative pressure inside, which causes the ink to flow out slowly. In addition, the bottle structure of the ink container containing different colors of ink is consistent, and the user cannot distinguish the ink container containing different colors of ink. Generally, the above technical problems can be solved by arranging multiple outflow pipelines and identification parts of different shapes. However, when the ink container is provided with multiple outflow pipelines and identification parts at the same time, the ink outlet of the ink container and the ink inlet of the printing device are relatively large in size, which is not conducive to the miniaturization trend of the printing device. CONTENT OF THE UTILITY MODEL

[0004] The present application provides an ink container to solve the problem of large size when multiple outflow pipelines and identification parts are arranged in the existing ink container at the same time.

[0005] The ink container provided by the embodiment of the present application is used to supplement ink for a printing device, the printing device has an ink inlet, the ink inlet has an identified part and multiple supply needles, and the ink container includes:

[0006] A container body, the container body has a containing cavity for storing ink and an opening communicating with the containing cavity;

[0007] An ink outlet forming part, the ink outlet forming part is arranged at the opening, and the ink outlet forming part has an ink outlet, and the ink in the container body can flow out from the ink outlet;

[0008] The ink outlet is provided with an identification part and multiple supply pipelines, and when the ink container is installed on the printing device, the identification part is used to cooperate with the identified part to distinguish different types of ink containers, and the supply pipeline is used to cooperate with the supply needle.

[0009] In a possible design, the identification part is formed on the ink outlet by removing part of the ink outlet.

[0010] In one possible design, the identification part is an identification pipe, and the identified part is an identification needle. The identification pipes of ink containers with different color inks are different in shape or position.

[0011] In one possible design, the identification pipe extends from the ink outlet part to the inside of the ink container, and the identification pipe is a hollow structure.

[0012] In one possible design, the identification part includes a first positioning surface, and the first positioning surfaces of ink containers with different color inks are different in shape or position.

[0013] In one possible design, the identification part includes an identification groove, and the outer peripheral surface of the supply pipe is partially recessed to form the identification groove. The identification grooves of ink containers with different color inks are different in shape or position.

[0014] In one possible design, the supply pipe includes an ink supply pipe and an air supply pipe, and the supply needle includes an ink supply needle and an air supply needle. The ink supply pipe is configured to cooperate with the ink supply needle, and the air supply pipe is configured to cooperate with the air supply needle.

[0015] In one possible design, the ink container further includes an air guide pipe. The air guide pipe is in communication with the air supply pipe, and the air guide pipe extends into the accommodation cavity when the ink outlet forming part is connected to the opening.

[0016] In one possible design, the supply pipe is provided with positioning columns and support ribs. The supply needle is capable of abutting against the positioning columns, and the support ribs are connected between the positioning columns and the inner wall of the supply pipe.

[0018] In the present application, when the ink container is installed on the ink inlet part of the printing device, the identification part cooperates with the identified part, which means that the ink stored in the ink container is suitable for supplementing the ink supply unit of the printing device. At this time, the supply pipe is capable of engaging with the supply needle. Since the identification part is arranged on the ink outlet part and the identification part is formed on the ink outlet part by removing part of the ink outlet part, the volume of the ink outlet part is not increased, which is beneficial to the miniaturization of the printing device.

[0019] It should be understood that the foregoing general description and the following detailed description are only exemplary and are not limiting to the present application. BRIEF DESCRIPTION OF DRAWINGS

[0069] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0070] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0071] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0072] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0073] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0074] As Figure 1 and Figure 2As shown, the ink container according to the embodiments of the present application is used to supply ink to a printing device. The printing device has an ink inlet portion 7, and the ink inlet portion 7 has an identified portion and a supply needle. Wherein, Figure 1 The X direction shown in the figure is the height direction of the ink container.

[0075] As shown, Figure 3 and Figure 4 The ink container includes: a container body 1 and an ink outlet forming portion 2, the container body 1 has a containing cavity 11 for storing ink and an opening 12 communicating with the containing cavity 11; the ink outlet forming portion 2 is arranged at the opening 12, and the ink outlet forming portion 2 has an ink outlet portion, and the ink in the container body 1 can flow out from the ink outlet portion.

[0076] The ink outlet portion is provided with an identified portion and a plurality of supply channels, and when the ink container is mounted on the ink inlet portion 7 of the printing device, the identified portion is used to cooperate with the identified portion to distinguish different kinds of ink containers, and the supply channel is used to cooperate with the supply needle.

[0077] When the ink container is mounted on the ink inlet portion 7 of the printing device, the identified portion cooperates with the identified portion, which means that the ink stored in the ink container is suitable for supplementing the ink supply unit of the printing device, and at this time the supply channel can be engaged with the supply needle. At this time, the identified portion can be engaged with the identified portion. Since the identified portion is arranged on the ink outlet portion, and the identified portion is formed on the ink outlet portion by removing part of the ink outlet portion, the volume of the ink outlet portion will not be increased, which is beneficial to the miniaturization of the printing device.

[0078] Specifically, the supply channel includes an ink supply channel 21 and an air supply channel 22, and the supply needle includes an ink supply needle 71 and an air supply needle 72, the ink supply channel 21 is used to cooperate with the ink supply needle 71, and the air supply channel 22 is used to cooperate with the air supply needle 72.

[0079] In this embodiment, the number of ink supply channels 21 and air supply channels 22 is one, and in other possible cases, the ink container can also have a plurality of ink supply channels 21 and a plurality of air supply channels 22, and the corresponding ink inlet portion 7 can have a plurality of ink supply needles 71 and a plurality of air supply needles 72, and the shape and position of the ink supply channel 21 correspond to the shape and position of the ink supply needle 71. It can be understood that the shapes of the plurality of ink supply channels 21 can be the same or different.

[0080] The ink supply channel 21 can cooperate with the ink supply needle 71, and the air supply channel 22 can cooperate with the air supply needle 72, so that the ink in the ink container can flow to the ink supply unit through the ink supply channel 21, realizing the ink supply to the printing device; when the ink is supplied through the ink supply channel 21, the air supply channel 22 can supplement the air in the containing cavity 11, preventing the negative pressure in the containing cavity 11 from being formed with the loss of ink, hindering the outflow of ink, and further ensuring that the ink can flow out at a stable and faster speed when the ink container supplies ink.

[0081] As shown in Figure 4 , the container body 1 is provided with an external thread structure at one end where the opening 12 is arranged, and the ink outlet forming part 2 is provided with an internal thread structure at one end for connecting with the container body 1, so that the container body 1 and the ink outlet forming part 2 can be stably connected through the thread structure. In other possible cases, the container body 1 and the ink outlet forming part 2 can also be integrally formed.

[0082] As shown in Figure 5 , the ink container further comprises a sealing valve 5, which is arranged in the supply pipeline, i.e. the sealing valve 5 is arranged in the ink supply pipeline 21 and the air supply pipeline 22. The sealing valve 5 has a self-closing notch thereon, which is closed when the ink container is not matched with the ink inlet part 7, so as to prevent the ink in the containing cavity 11 from leaking through the self-closing notch; when the ink container is matched with the ink inlet part 7, the ink supply needle 71 can extend into the ink supply pipeline 21 through the self-closing notch, and the air supply needle 72 can extend into the air supply pipeline 22 through the self-closing notch. Optionally, the self-closing notch is in the shape of a straight line, a cross or a rice grain. In other possible cases, the sealing valve 5 can also be a movable poppet valve.

[0083] More specifically, as shown in Figure 5 , a sealing gasket 4 is arranged between the container body 1 and the ink outlet forming part 2, and the sealing gasket 4 abuts against the end face of the container body 1 where the opening 12 is arranged, so as to prevent the ink in the container body 1 from flowing out from between the container body 1 and the ink outlet forming part 2 after the ink outlet forming part 2 is connected to the container body 1, and polluting the container body 1 and the ink outlet forming part 2.

[0084] In addition, one of the container body 1 and the ink outlet forming part 2 is provided with a clamping block 13, and the other is provided with a clamping groove 20, and the clamping block 13 is clamped in the clamping groove 20, so that the connection between the ink outlet forming part 2 and the container body 1 is more stable. The clamping groove 20 comprises a part extending along the circumference of the ink outlet forming part 2 and a part extending along the height direction X of the ink outlet forming part 2, and the clamping block 13 can enter the clamping groove 20 from the part extending along the height direction X of the ink outlet forming part 2 of the clamping groove 20, and then move to the end of the clamping groove 20 along the part extending along the circumference of the ink outlet forming part 2 of the clamping groove 20, so as to realize clamping of the two, and prevent the ink outlet forming part 2 from being separated from the container body 1.

[0085] In a possible implementation, as shown in Figures 1-7As shown, the ink supply pipe 21 and the air supply pipe 22 are both located inside the ink outlet section, and the diameter of the ink supply pipe 21 is larger than the diameter of the air supply pipe 22. When the ink container is inverted and just connected to the ink inlet section, the ink flows slowly in the air supply pipe 22 and flows quickly in the ink supply pipe 21. Therefore, under the combined action of hydraulic and air pressure, the ink flows out of the receiving cavity 11 from the ink supply pipe 21, and the gas flows into the receiving cavity 11 from the air supply pipe 22, realizing gas-liquid separation.

[0086] Optional, such as Figure 4 and Figure 5 As shown, the ink container also includes an air guide tube 3, which is connected to the air supply pipe 22. When the ink outlet forming part 2 is connected to the opening 12, the air guide tube 3 extends into the receiving cavity 11. When the ink container supplies ink to the ink supply unit, outside air can enter the receiving cavity 11 through the air supply pipe 22 and the air guide tube 3. Since the air guide tube 3 extends to the bottom of the receiving cavity 11, the air entering the receiving cavity 11 will not agitate the ink in the receiving cavity 11, allowing the ink container to supply ink stably. At the same time, the fact that the air guide tube 3 extends to the bottom of the receiving cavity 11 also reduces the probability of ink leakage in the receiving cavity 11 through the air guide tube 3 and the air supply pipe 22.

[0087] like Figure 7 As shown, the gas supply pipe 22 has a tubular extension section, the outer diameter of which is close to the inner diameter of the gas guide pipe 3, so that the end of the gas guide pipe 3 can be fitted onto the tubular extension section of the gas supply pipe 22.

[0088] In another possible implementation, such as Figures 8-17 As shown, the ink supply pipe 21 and the air supply pipe 22 have the same structure, consisting of two adjacent cylinders. The ink supply pipe 21 and the air supply pipe 22 form the ink outlet. The ink container can automatically select one pipe as the ink supply pipe 21 and the other as the air supply pipe 22 to maintain the gas-liquid balance inside the ink container. Understandably, due to the different heights of the ink supply needle 71 and the air supply needle 72, under atmospheric pressure, the taller one will generally be preferentially selected as the air supply needle 72, and the shorter one as the ink supply needle 71.

[0089] Specifically, such as Figure 12 and Figures 15-17 As shown, a positioning post 27 and a support rib 28 may also be provided inside the supply pipe. The supply needle can abut against the positioning post 27, and the support rib 28 connects the positioning post 27 to the inner wall of the supply pipe. A positioning post 27 is provided inside the ink supply pipe 21 and / or the air supply pipe 22, and the ink supply needle 71 and / or the air supply needle 72 can abut against the positioning post 27, thereby providing support for the ink container. By placing the positioning post 27 inside the ink container, ink leaking from the ink supply pipe 21 can be prevented from adhering to the printing device through the area where the ink container contacts the ink inlet 7.

[0090] Specifically, as shown in Figure 15 The support rib 28 is connected between the positioning column 27 and the inner wall of the ink supply pipe 21 or the gas supply pipe 22. The support rib 28 is connected to the end of the positioning column 27 close to the accommodation cavity 11, and provides support for the positioning column 27, so that the positioning column 27 can stably abut against the ink supply needle 71 or the gas supply needle 72 and does not shake when abutting against the ink supply needle 71 or the gas supply needle 72.

[0091] Further, the supply pipe has positioning protrusions 272 between which are recesses through which the ink flows. When the positioning protrusions 272 abut against the supply needle, the supply substance can flow through the recess, i.e., the ink in the accommodation cavity 11 can flow from the recess to the ink supply needle 71, and the gas in the gas supply needle 72 can flow into the accommodation cavity 11. Figure 16 and Figure 16 The positioning column 27 has a plurality of positioning pieces 271, and the positioning protrusions 272 are located on the side of the positioning pieces 271 away from the container body 1.

[0092] Optionally, the positioning column 27 can include three evenly distributed positioning pieces 271, and the end of each of the three positioning pieces 271 is provided with a positioning protrusion 272. Optionally, the positioning column 27 includes only one positioning piece 271, and the end of the positioning piece 271 has a plurality of spaced-apart positioning protrusions 272. Optionally, the positioning column 27 includes only one positioning piece 271, and the end of the positioning piece 271 is provided with only one annular positioning protrusion 272. The positioning piece 271 has a communication hole capable of communicating with the ink supply needle 71 or the gas supply needle 72, and the ink or air can flow through the communication hole.

[0093] As shown in Figure 16 The support rib 28 includes a first support portion 281 extending in the radial direction of the ink supply pipe 21 or the gas supply pipe 22 and a second support portion 282 extending in the axial direction of the ink supply pipe 21 or the gas supply pipe 22. The second support portion 282 is arranged on the inner wall of the ink supply pipe 21 or the gas supply pipe 22, one end of the first support portion 281 is connected to the second support portion 282, and the other end is connected to the positioning column 27.

[0094] The second supporting part 282 extending along the axial direction of the ink supply channel 21 or the gas supply channel 22 can increase the strength of the ink supply channel 21 or the gas supply channel 22, and reduce the probability of damage to the ink outlet. It can be understood that the number of the supporting ribs 28 can be consistent with the number of the positioning pieces 271, or can not be consistent. Optionally, the supporting ribs 28 can not have gaps therebetween, and in this case, a communication hole needs to be arranged in the middle of the positioning column 27 to communicate the accommodating cavity 11 and the ink supply needle 71 and the gas supply needle 72.

[0095] As shown in Figure 18 , the ink supply channel 21 and / or the gas supply channel 22 is provided with a mounting protrusion 29, the mounting protrusion 29 is located on the side of the second supporting part 282 away from the container main body 1, and the sealing valve 5 is mounted between the mounting protrusion 29 and the second supporting part 282. The mounting protrusion 29 and the second supporting part 282 can limit the sealing valve 5, so that the sealing valve 5 is stably mounted at the end of the ink supply channel 21 and / or the gas supply channel 22, and prevent the sealing valve 5 from falling off or moving towards the container main body 1. Preferably, a plurality of mounting protrusions 29 are arranged at intervals along the circumferential direction of the ink supply channel 21 or the circumferential direction of the gas supply channel 22, and the mounting protrusions 29 have guide surfaces arranged at intervals in the axial direction of the ink supply channel 21 or the gas supply channel 22, so as to facilitate the mounting and dismounting of the sealing valve 5.

[0096] Further, the top end of the positioning column 27 can serve as a second positioning surface to position the relative positions of the ink container and the ink inlet 7. Specifically, the height of the gas supply needle 72 is higher than the height of the ink supply needle 71, the positioning column 27 in the gas supply channel 22 abuts against the gas supply needle 72, and the positioning column 27 in the ink supply channel 21 does not contact the ink supply needle 71, i.e., the second positioning surface is located in the gas supply channel 22, thereby preventing ink from remaining on the area where the printing device contacts the ink container after the ink container finishes replenishing ink for the printing device.

[0097] Optionally, the height of the ink supply needle 71 is higher than the height of the gas supply needle 72, the positioning column 27 in the ink supply channel 21 abuts against the ink supply needle 71, and the positioning column 27 in the gas supply channel 22 does not contact the gas supply needle 72, i.e., the second positioning surface is located in the ink supply channel 21.

[0098] Optionally, the upper surface of the positioning protrusion 272 is perpendicular to the axis of the ink supply channel 21 or the gas supply channel 22, i.e., when the ink container is mounted on the ink inlet 7 of the printing device, the upper surface of the positioning protrusion 272 can serve as a second positioning surface.

[0099] In the above embodiments, as shown in Figure 4As shown, the ink container further comprises a bottle cap 6, which can cover the ink outlet forming portion 2 to protect the ink outlet forming portion 2. The bottle cap 6 is provided with an internal thread, and the outer periphery of the ink outlet forming portion 2 is provided with an external thread. The internal thread cooperates with the external thread to enable the bottle cap 6 to be stably connected with the ink outlet forming portion 2. Preferably, the bottle cap 6 is provided with a recessed gripping portion 61, and the user can insert a finger into the gripping portion 61 to increase the friction between the finger and the bottle cap 6, thereby enabling the bottle cap 6 to be more conveniently and labor-savingly removed from the ink outlet forming portion 2.

[0100] Further, as shown in Figure 12 、 Figure 18 and Figure 2 , the container body 1 is reduced in diameter near the opening 12, so that when the bottle cap 6 covers the ink outlet forming portion 2, the ink container as a whole has a cylindrical shape.

[0101] In the above embodiments, the identification portion is located at the ink outlet portion, and the identification portion is formed in the ink outlet portion in a manner of removing part of the ink outlet portion, so that the setting of the identification portion does not increase the volume of the ink outlet portion, which is beneficial to the miniaturization of the printing device.

[0102] Regarding the specific structure of the identification portion, the present application provides the following embodiments.

[0103] Embodiment One

[0104] As shown in Figure 6 and Figure 3 , the identification portion is an identification pipe 23, and the identified portion is an identification needle 73. The identification pipe 23 extends from the surface of the ink outlet portion away from the container body 1 to the inside of the ink container, as shown in Figure 6 , the identification pipe 23 extends downward from the upper end surface of the ink container. The identification pipe 23 has a hollow structure, and the identification needle 73 can be inserted into the identification pipe 23. The shapes or positions of the identification pipes of ink containers containing different color inks are different.

[0105] The colors of the inks stored in different ink containers can be different, and each color of ink corresponds to an identification pipe 23 of a certain shape, so that by setting identification needles 73 of different shapes at the ink supply unit, the ink supply unit is only correctly engaged with the ink container storing the ink of the required color. Optionally, the cross section of the identification pipe 23 is circular, triangular, square, rectangular, pentagonal, etc. The ink colors can be black, red, yellow, cyan.

[0106] In a possible case, the height of the identification needle can be higher than that of the supply needle, and the identification needle 73 can abut against the bottom wall of the identification pipe 23 to support the ink container.

[0107] In the present embodiment, by arranging the identification pipe 23 inside the ink outlet, the presence of the identification pipe 23 does not increase the external volume of the ink outlet, and the volume of the ink inlet of the printer is also reduced.

[0108] Embodiment Two

[0109] Embodiment Two is a modification of Embodiment One.

[0110] In the present embodiment, as shown in Figure 13 , the identification part includes a first positioning surface 24, and the first positioning surface 24 of the ink container with different color inks has different shapes or positions.

[0111] The first positioning surface 24 is used to cooperate with the ink inlet 7. The ink inlet 7 can have a groove that can be fitted with the ink outlet, and by cooperation of the first positioning surface 24 with the groove, when the ink container is provided with multiple supply needles, the ink container can only be fitted with the ink inlet 7 at a specific angle, at this time, the position of the first positioning surface 24 needs to correspond to the position of the groove, and by arranging the first positioning surface 24, the difficulty of cooperation between the identification pipe 23 and the identification needle 73 is reduced, the difficulty of cooperation between the ink supply pipe 21 and the ink supply needle 71 is reduced, and the difficulty of cooperation between the gas supply pipe 22 and the gas supply needle 72 is reduced.

[0112] Optionally, the ink outlet is cylindrical, and the first positioning surface 24 is a flat surface formed on the ink outlet by cutting part of the ink outlet. It can be understood that the first positioning surface 24 can also be a flat surface or an inclined surface protruding on the ink outlet.

[0113] In other possible cases, the ink container can also have multiple positioning surfaces, and the positioning surfaces are arranged continuously, that is, a V-shaped identification structure is formed on the outer circumferential surface of the ink outlet by cutting at different angles, and the ink inlet 7 has a groove with a corresponding shape and position.

[0114] In other possible cases, the multiple positioning surfaces can be arranged separately, that is, the positioning surfaces are not continuous.

[0115] In the present embodiment, by cutting the outer circumferential surface of the ink outlet to form the first positioning surface 24, the arrangement of the identification part does not increase the external volume of the ink outlet, and the volume of the ink inlet of the printer is also reduced.

[0116] Embodiment Three

[0117] The present embodiment is a modification of the ink outlet forming part 2 on the ink outlet of Embodiment One.

[0118] In the present embodiment, as shown in Figure 14 and Figure 14As shown, the identification part is an identification groove, the identification groove includes a first identification groove 26, the outer peripheral surface part of the ink outlet part is recessed to form the first identification groove 26, the shapes or positions of the first identification grooves 26 of the ink containers filled with different color inks are different. Among them, the first identification groove 26 does not increase the volume of the ink outlet part, which is beneficial to the miniaturization of the printing device.

[0119] For example, when the number of the ink supply pipeline 21 and the air supply pipeline 22 is one, the ink supply pipeline 21 and the air supply pipeline 22 are arranged in close proximity, the first identification groove 26 is formed at the position adjacent to the ink supply pipeline 21 and the air supply pipeline 22, so that the setting of the first identification groove 26 does not reduce the pipe diameter of the ink supply pipeline 21 and the air supply pipeline 22, and ensures that the ink supply speed of the ink container is faster.

[0120] When the ink color in the ink supply unit is consistent with the ink color in the ink container, the structure of the identified part corresponds to the structure of the first identification groove 26, the first identification groove 26 can cooperate with the identified part, so that the ink supply unit is only correctly engaged with the ink container storing the required color ink, and the ink container can only cooperate with the ink inlet part 7 at a specific angle, thereby reducing the difficulty of cooperation between the ink supply pipeline 21 and the ink needle 71, and reducing the difficulty of cooperation between the air supply pipeline 22 and the air needle 72. When the ink color in the ink supply unit is inconsistent with the ink color in the ink container, the structure of the identified part does not correspond to the structure of the first identification groove 26, the first identification groove 26 cannot cooperate with the identified part, so that the ink container cannot cooperate with the ink inlet part 7, thereby preventing the filling of the wrong color ink into the printing device.

[0121] Further, the identification part also has an identification rib 25, the identification rib 25 is located on the outer periphery of the supply pipeline. On the one hand, the identification rib 25 can cooperate with the first identification groove 26 at the same time, thereby improving the accuracy of cooperation between the identification part and the identified part; on the other hand, the identification rib 25 can play a protective role for the supply pipeline. Optionally, the identification rib 25 is part of the outer peripheral wall of the supply pipeline, and a plurality of identification ribs 25 and a plurality of first identification grooves 26 are staggered.

[0122] As shown in Figure 15 and ​ , the identification groove also includes a second identification groove 251, the identification rib 25 is partially recessed to form the second identification groove 251, so that the setting of the second identification groove 251 also does not increase the external volume of the ink outlet part. The first identification groove 26, the identification rib 25 and the second identification rib 251 can cooperate with each other and cooperate with the identified part, thereby improving the accuracy of cooperation between the identification part and the identified part again.

[0123] Preferably, the volume of the second identification groove 251 is smaller than the volume of the first identification groove 26, so that the second identification groove 251 has less influence on the strength of the identification rib 25. One second identification groove 251 can be provided on each identification rib 25, or a plurality of second identification grooves 251 can be provided at intervals.

[0124] In the present embodiment, the first identification groove 26 is formed by partially recessing the outer circumferential surface of the ink outlet portion, so that the provision of the identification portion does not increase the external volume of the ink outlet portion, and the volume of the ink inlet portion of the printer is also reduced. Meanwhile, the outer circumferential wall of the ink outlet portion serves as the identification rib 25, and the second identification groove 251 is formed by partially recessing the identification rib 25. The first identification groove 26, the identification rib 25, and the second identification groove 251 cooperate with each other and with the identified portion, so that the identification portion and the identified portion cooperate with high accuracy.

[0125] The above merely provides preferred embodiments of the present application, but should not be used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
