[0099] In the field of inkjet printing, currently, a tray-type housing paired with an ink bag-type liquid storage device is a relatively common type of large-capacity split ink cartridge solution. During installation, the ink bag needs to be vertically inserted into the housing from top to bottom. There is a protruding portion extending along the installation direction inside the housing to guide the installation of the liquid storage device. The liquid storage device includes a connection component, and a chip is provided on the connection component. The chip is used to contact the electrical connection portion on the printer installation part to achieve electrical connection. After the existing liquid storage device is installed in the housing, there is a relatively large movement space, which is insufficient to ensure the contact stability between the chip on the liquid storage device and the electrical connection portion.

[0100] The following will specifically describe the technical solutions of the present invention and how the technical solutions of the present invention solve the above technical problems with specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0101] For convenience of description, with reference to the accompanying drawings, in this article, the Y-axis direction is defined as the first direction, the X-axis direction is defined as the second direction, and the Z-axis direction is defined as the third direction.

[0102] As Figure 1 shown, the specific structure of the installation part 50 of the inkjet printer includes a fixing frame. The fixing frame is provided with an ink injection tube 51, a printer electrical connection portion 52, columnar positioning portions 53f, 53s, and a locking portion 54. The locking portion 54 is a rod-shaped member that can be reset and swing. The rod-shaped member has a protrusion extending in the -Z direction at the movable end. The protrusion is used to cooperate with the groove at the bottom of the housing 20 to fix the assembly composed of the housing 20 and the liquid storage device 10. The printer electrical connection portion 52 can be electrically connected to the chip thereon when the assembly is installed on the installation part 50. The printer electrical connection portion 52 includes multiple contact pins (not marked in the figure) made of elastic conductive steel sheets. Specifically, the above assembly is installed or removed along the +Y and -Y directions in the figure. This assembly is physically engaged with the installation part through the housing and is electrically connected to the electrical connection portion 52 through the chip located on the liquid storage device.

[0103] Embodiment 1

[0104] As Figure 2 shown, the liquid storage device 10 includes a connection component 11 and a liquid storage body 12 for storing liquid. The connection component 11 is arranged at the front end of the liquid storage body 12 along the first direction, that is, the connection component 11 is located at one end of the liquid storage body 12 in the +Y direction. The connection component 11 is recessed at the end in the +Y direction to form an electrical connection portion 13, and a chip 14 is inclinedly installed on the electrical connection portion 13.

[0105] As Figure 3 and Figure 4As shown, the housing 20 includes a bottom plate 21 and an outer frame 22 provided at the edge of the bottom plate 21.

[0106] The bottom plate 21 is a rectangular plate, and the length of the bottom plate 21 in the Y-axis direction is greater than the length of the bottom plate 21 in the X-axis direction.

[0107] The outer frame 22 includes a front baffle 221, a rear baffle 222, two side baffles 223 and two side edges 224. The front baffle 221 is provided at the +Y-direction end edge of the bottom plate 21, the rear baffle 222 is provided at the -Y-direction end edge of the bottom plate 21, the two side baffles 223 are oppositely arranged at the edges of the bottom plate 21 in the +X and -X directions, the side edges 224 protrude at the junction of the side baffle 223 and the bottom plate 21, the side edges 224 extend in the Y-axis direction, both ends of each side baffle 223 are integrally connected to the front baffle 221 and the rear baffle 222, two protruding portions 23 are vertically provided at the first end of the bottom plate 21. In this embodiment, the protruding portions 23 are columnar members. A first notch 211 is provided at the +Y-direction end edge of the bottom plate 21, the length of the side edge 224 is less than the length of the bottom plate 21 in the Y-axis direction, and the end face of the side edge 224 close to the front baffle 221 is a cut-off surface 227. A wedge-shaped convex portion 213 is provided at the corresponding position of the bottom plate 21 at the +Y-direction end edge and the chip 14, and the included angle between the upper surface of the wedge-shaped convex portion 213 and the inner wall surface of the front baffle 221 is an obtuse angle.

[0108] A guiding groove 214 (not marked in the figure, reference can be made to Figures 1 to 3 and Figure 11 and Figure 19 to understand this structure) for cooperating with the locking portion 54 is provided at the bottom of the bottom plate 21. The liquid containing device 10 is installed in the installation portion 50 by means of the housing 20. The housing 20 includes positioning holes 24 for cooperating with the positioning portions 53f, 53s, and the guiding groove 214 and the wedge-shaped convex portion 213 at least partially overlap in the X direction.

[0109] The connecting member 11 is located above the +Y-direction end of the bottom plate 21. In the X-axis direction, the connecting member 11 is at least partially between the two protruding portions 23. The bottom of the connecting member 11 at least partially fits with the bottom plate 21. A first through notch 225 is provided at the upper edge of the front baffle 221 in the +Z direction. A liquid outlet portion 111 for cooperating with the first through notch 225 is provided on the +Y-direction side of the connecting member 11. The outer end of the liquid outlet portion 111 protrudes from the outer wall of the front baffle 221, that is, the liquid outlet portion 111 passes through the front baffle 221 through the first through notch 225. It can be understood that the liquid outlet portion 111 is communicated with the liquid containing body 12.

[0110] Refer to Figure 3As shown, the liquid containing device 10 further includes a first limiting member 151. The first limiting member 151 is provided on the connecting member 11. When the liquid containing device 10 is placed in the housing 20, the first limiting member 151 cooperates with the front baffle 221 to limit the liquid containing device. Thereby, the stability of the connection between the liquid containing device and the housing is improved, and further the contact stability between the chip on the liquid containing device and the electrical connection part of the printer is improved.

[0111] Moreover, since the connecting member 11 provided with the chip 14 is located at the front end of the liquid containing body 12 in the first direction, and the first limiting member 151 cooperates with the front baffle 221 to limit the liquid containing device, this makes the position of the limiting cooperation closer to the chip 14, thereby further improving the contact stability between the chip and the electrical connection part of the printer.

[0112] Continue to refer to Figures 2 to 4 As shown, the first limiting member 1 includes a first limiting portion provided at the front end of the connecting member 11 in the first direction. When the liquid containing device is placed in the housing 20, the first limiting portion cooperates with the front baffle 221 to at least limit the movement of the liquid containing device 10 in the first direction.

[0113] Refer to Figure 2 and Figure 3 As shown, the first limiting portion is provided at one end of the liquid outlet portion 111 protruding from the front baffle 221 and abuts against the front baffle 221.

[0114] Wherein, a clamping gap for the front baffle 221 to enter is formed between the first limiting portion and the front end of the connecting member 11, thereby realizing the limitation of the liquid containing device.

[0115] Refer to Figure 2 and Figure 3 As shown, the first limiting portion specifically includes a first limiting plate 151a.

[0116] In other implementation manners, the first limiting portion can also be provided at a position outside the liquid outlet portion 111 at the front end of the connecting member 11, and can also limit the liquid containing device in the Y-axis direction.

[0117] Continue to refer to Figure 2 and Figure 3 As shown, the first limiting member 151 further includes a second limiting portion. The second limiting portion includes a second limiting plate 151b. The second limiting portion is provided at the front end of the connecting member 11 in the first direction. The second limiting portion cooperates with the front baffle 221 to at least limit the movement of the liquid containing device in the second direction (X-axis). That is to say, the liquid containing device is limited in the X-axis direction and the Y-axis direction through the second limiting portion and the first limiting portion, further improving the stability of the liquid containing device.

[0118] The front baffle 221 is further provided with a second through notch 226 communicating with the first through notch 225 at the upper edge. In the X-axis direction, the two ends of the second through notch 226 are respectively located on both sides of the first through notch 225. In the Z-axis direction, the length of the second through notch 226 is less than the length of the first through notch 225. The second limiting portion is in limiting cooperation with the second through notch 226.

[0119] The second limiting portion includes two second limiting plates 151b abutting against the side edges of the second through notch 226. That is, the two second limiting plates 151b are respectively arranged on the opposite sides of the liquid outlet portion 111 in the second direction, and the two second limiting plates 151b respectively abut against the two side edges of the second through notch 226.

[0120] The liquid outlet portion 111 includes two fitting sides 112 abutting against both sides of the first through notch 225. By making the two fitting sides 112 abut against both sides of the first through notch 225, the liquid containing device is limited at least in the second direction, further improving the connection stability between the liquid containing device and the housing.

[0121] Continue to refer to Figure 2 and Figure 3 As shown, the number of the first limiting plates 151a is two, and the two first limiting plates 151a are respectively arranged on the two fitting sides 112. By setting the first limiting plates 151a to two, the liquid containing device can be limited from multiple positions, further improving the limiting effect, and further improving the contact stability between the chip 14 and the electrical connection portion.

[0122] The outer ends of the second limiting plates 151b are located outside the front baffle 221, and the lower edges of the second limiting plates 151b abut against the lower edge of the second through notch 226. Such a setting enables the lower edge of the second through notch 226 to support and limit the second limiting plates 151b, that is, to limit the Z-axis to a certain extent, further improving the overall limiting effect on the liquid containing device. Specifically, in implementation, the upper edge of the side baffle 223 can be flush with the upper edge of the front baffle 221.

[0123] Continue to refer to Figure 2 and Figure 3 As shown, the first limiting member 151 further includes a third limiting portion connected to the second limiting portion. The third limiting portion is located outside the front baffle 221 and abuts against the front baffle 221. That is to say, through the abutting cooperation between the third limiting portion and the front baffle 221, the liquid containing device can be prevented from moving along the -Y axis to a certain extent, thereby further improving the stability of the liquid containing device, and further improving the contact stability between the chip 14 and the electrical connection portion.

[0124] Refer to Figure 3As shown, the third limiting part is connected to the side of the outer end of the second limiting part facing away from the liquid outlet part 111. The third limiting part includes a third limiting plate 151c. For example, a third limiting plate 151c that abuts against the front baffle 221 is provided on the side of the outer end of the second limiting plate 151b facing away from the liquid outlet part 111.

[0125] By connecting the third limiting part and the second limiting part, the structural strength of the whole of the second limiting part and the third limiting part can be improved, thereby further ensuring the limiting effect on the liquid containing device.

[0126] Among them, the upper edge of the third limiting part can be flush with the upper edge of the front baffle 221, and the upper edge of the second limiting part can be flush with the upper edge of the front baffle 221. In this way, the setting of the third limiting part and / or the second limiting part will not interfere with other components, and the appearance flatness of the whole device is improved.

[0127] In the X-axis direction, the chip 14 is located between the liquid outlet part 111 and a third limiting plate 151c. Such a setting makes the limiting position closer to the chip 14, thereby further improving the contact stability between the chip 14 and the electrical connection part.

[0128] Avoidance notches 16 that cooperate with the convex parts 23 are provided at both ends in the X-axis direction on the side of the connecting part 11 away from the front baffle 221.

[0129] The connecting part 11 is engaged with the front baffle 221 through the liquid outlet part 111 and the first limiting plate 151a at the first through notch 225, and is engaged with the front baffle 221 through the second limiting plate 151b and the third limiting plate 151c at the second through notch 226. It can ensure the limiting of the liquid containing device 10 in the length and width directions of the housing 20, and the connection point between the liquid containing device 10 and the housing 20 is closer to the chip 14, which can improve the contact stability between the chip 14 and the printer electrical connection part 52.

[0130] Embodiment 2

[0131] This application provides a liquid containing device. The housing 20 in this embodiment is the same as that in Embodiment 1, and the specific structure can be referred to Figure 4 . The main difference between the liquid container 12 involved in this embodiment and that in Embodiment 1 lies in the limiting member 152. As Figures 5 - 9 shown, the liquid containing device provided in this embodiment is detachably installed in the housing 20; the housing 20 includes a bottom plate 21, the liquid containing device is located on the bottom plate 21, and a first notch 211 is provided at the edge of the first end of the bottom plate 21.

[0132] The liquid containing device includes a liquid container 12 and a connecting component 11. The connecting component 11 is fixed to one end of the liquid container 12 near the first notch 211, and a chip 14 is provided at the first end edge of the connecting component 11 close to the bottom plate 21. The connecting component 11 includes a body and a limiting member 152, and the limiting member 152 is located on the side of the body close to the bottom plate 21. The limiting member 152 in this embodiment includes a penetrating portion 152a and a clamping portion 152b. The top end of the penetrating portion 152a is fixedly connected to the body. The bottom end of the penetrating portion 152a extends from the first notch 211 to the lower side of the bottom plate 21. The clamping portion 152b is provided at the bottom end of the penetrating portion 152a, and at least part of the projection of the clamping portion 152b on the bottom plate 21 falls outside the first notch 211.

[0133] It should be noted that in this embodiment, the limiting member 152 is provided in the area corresponding to the first notch 211 at the bottom of the connecting component 11. The limiting member 152 is hooked to the bottom plate 21 at the first notch 211. Specifically, the limiting member 152 includes a penetrating portion 152a and a clamping portion 152b. The lower end of the penetrating portion 152a is located below the bottom plate 21. The clamping portion 152b protrudes from the -Y direction side of the lower end of the penetrating portion 152a, and the clamping portion 152b abuts against the side of the bottom plate 21 facing away from the liquid container 12. That is, the liquid container 12 in this embodiment can achieve the limit in the X and Z directions with the housing 20 through the limiting member 152 hooked to the bottom of the bottom plate 21. Since the clamping portion 152b abuts against the lower side of the bottom plate 21, the moving space in the Y direction is extremely small, which can ensure the stable assembly of the liquid container 12. There is no need to provide other connection structures on the liquid container 12 that cooperate with the housing 20, nor is it necessary to provide connection structures that cooperate with the printer installation part, which helps to reduce the manufacturing cost of related consumables. And since the limiting member 152 is relatively close to the chip 14, the contact stability between the chip 14 and the printer electrical connection part can be improved.

[0134] In an alternative embodiment, as Figure 4 shown, the first notch 211 extends along the length direction of the bottom plate 21, and the extension length of the limiting member 152 along the width direction of the bottom plate 21 matches the opening width of the first notch 211.

[0135] The extension length of the above-mentioned limiting member 152 along the width direction of the housing 20 matches the opening width of the first notch 211 along the width direction of the housing 20. This setting method can make the two ends of the limiting member 152 abut against the two side end faces of the first notch 211, so as to achieve a more stable limiting effect in the X direction.

[0136] Possibly, in combination with Figure 4 and Figure 7, the contour of the first notch 211 is U-shaped, and the first notch 211 has an arc-shaped end wall surface 212. The side of the passing-through portion 152a facing the end wall surface 212 is an arc surface, and the radian of the arc surface matches the radian of the end wall surface 212.

[0137] It should be noted that the passing-through portion 152a matches the end wall surface 212 of the first notch 211, which can enable the arc surface of the passing-through portion 152a to achieve better abutment with the end wall surface 212 of the first notch 211, so as to achieve a more stable limiting effect in the Y direction.

[0138] Exemplarily, as Figure 8 shown, the passing-through portion 152a is arranged as an arc-shaped rib plate. The top end of the arc-shaped rib plate is fixedly connected to the main body, and the bottom end of the arc-shaped rib plate extends out of the bottom plate 21 from the first notch 211; the engaging portion is arranged as an arc-shaped protrusion, and the arc-shaped protrusion is arranged on the side surface of the bottom end of the arc-shaped rib plate, and the arc-shaped protrusion abuts against the bottom surface of the bottom plate 21 on the side opposite to the liquid container.

[0139] It can be understood that specifically, the passing-through portion 152a is an arc-shaped rib plate whose side surface fits the end wall surface 212, and the engaging portion 152b is the arc-shaped protrusion on the side surface of the arc-shaped rib plate of the passing-through portion 152a. The upper surface of the arc-shaped protrusion serving as the engaging portion 152b abuts against the lower surface of the bottom plate 21 at the edge of the end wall surface 212. Using a rib plate as the passing-through portion 152a can ensure the strength of the limiting member 152 and reduce the risk of damage caused during the abutment process of the limiting member 152 with the bottom plate 21.

[0140] In one implementation, as Figure 4 shown, the above-mentioned housing 20 includes a plurality of baffles surrounding the four peripheral edges of the bottom plate 21. The housing 20 further includes a first through-notch 225 provided on the baffle. The plurality of baffles include a front baffle 221 and side baffles 223 located at both ends of the front baffle 221, and the first through-notch 225 is provided on the front baffle 221.

[0141] As Figure 6 and Figure 9 shown, the connecting component 11 includes a liquid outlet portion 111. The liquid outlet portion 111 is arranged at a position on the side surface of the main body corresponding to the above-mentioned first through-notch 225, and the end of the liquid outlet portion 111 facing away from the main body passes through the first through-notch 225 and protrudes outside the front baffle 221.

[0142] In this implementation, when viewed from the outside of the front baffle 221, the liquid outlet portion 111 is a protrusion surrounding the edge of the first through-notch 225. The ink from the protruding liquid outlet portion 111 can play a guiding role during the installation of the liquid container 12.

[0143] It should be noted that the first through-notch 225 and the first notch 211 may be connected or not, and can be set according to the specific structure of the connecting component.

[0144] Regarding the specific connection manner between the liquid container 12 and the connecting component 11, as Figure 6 shown, optionally, the body of the connecting component 11 has a receiving cavity (not shown in the figure). One end of the liquid container 12 close to the body is provided with a fixed joint 15, and the fixed joint 15 is snap-fitted into the receiving cavity. That is, the liquid container 12 is connected to the body of the connecting component 11 by snap-fitting, and then indirectly connected to the housing 20 through the body of the connecting component 11, thereby realizing the connection and fixation with the printer.

[0145] In order to facilitate the taking and placing of the liquid containing device, a gap can be provided between the body of the connecting component 11 and the front baffle 221.

[0146] In addition, as Figure 4 shown, the first end of the bottom plate 21 has two protruding portions 23, and at least part of the connecting component 11 is located between the two protruding portions 23.

[0147] It should be noted that these two protruding portions 23 are structures existing on the bottom plate 21 itself, and the two protruding portions 23 are provided at both ends of the bottom plate 21 in the X direction. In this application, the liquid container 12 is directly fixed to the bottom plate 21 of the housing 20 through a simple hook connection structure, which simplifies the connection structure. Therefore, when setting the connecting component 11 of this application, the connecting component 11 does not need to be connected to the housing 20 by means of the two protruding portions 23, and the local structure can make an avoidance for the two protruding portions 23.

[0148] Possibly, the distance between the end wall surface 212 of the first notch 211 and the front baffle 221 is less than the distance from the protruding portion 23 to the front baffle 221, that is, the end wall surface 212 of the first notch 211 is closer to the front baffle 221 than the protruding portion 23. With such a setting, the restricting member 152 is closer to the chip 14 than the protruding portion 23, which can improve the contact stability between the chip 14 and the printer electrical connection portion 52.

[0149] In a specific embodiment, as Figure 4 shown, the first notch 211 can be provided in the middle of the first end edge of the bottom plate 21, and the first through-notch 225 is correspondingly provided in the middle of the front baffle 221. In order to correspond to the position of the fixed joint 15 on the liquid container 12, setting the first notch 211 and the first through-notch 225 in the middle position can directly correspond to the fixed joint 15, reduce the complexity of the process, and facilitate the derivation of the ink in the liquid container 12.

[0150] On the other hand, refer to Figure 1, the present application also provides a printer, which includes an installation part 50 and an assembly. The assembly includes a housing 20 and the above-mentioned liquid containing device. The liquid containing device is connected to the housing 20, and the housing 20 is connected to the installation part 50; the installation part 50 includes an electrical connection part 52, and the liquid containing device is provided with a chip 14. When the housing 20 is connected to the installation part 50, the chip 14 is electrically connected to the electrical connection part 52. It should be emphasized that when the above-mentioned assembly is installed in the printer, the housing 20 is directly connected to the installation part 50 of the printer, and the liquid containing device is installed on the installation part 50 of the printer by being directly connected to the housing 20, and the liquid containing device itself is not connected to the installation part 50 of the printer.

[0151] This embodiment provides a liquid containing device 10, which is detachably installed in the housing 20; the housing 20 includes a bottom plate 21, the liquid containing device 10 is located on the bottom plate 21, the first end edge of the bottom plate 21 has a first notch 211, the liquid containing device includes a liquid containing body 12 and a connecting component 11, the connecting component 11 is fixed to one end of the liquid containing body 12 close to the first notch 211, and the connecting component 11 is provided with a chip 14 near the first end edge of the bottom plate 21; the connecting component 11 includes a body and a limiting member 152, and the limiting member 152 is located on the side of the body close to the bottom plate 21; the limiting member 152 includes a penetrating part 152a and a clamping part 152b, the top end of the penetrating part 152a is fixedly connected to the body, the bottom end of the penetrating part 152a extends from the first notch 211 to the lower side of the bottom plate 21, and the clamping part 152b is arranged at the bottom end of the penetrating part 152a, and the projection of the clamping part 152b on the bottom plate 21 at least partially falls outside the first notch 211. The liquid containing device 10 provided by the present application has a simple structure and can ensure relative fixation with the installation part of the printer, thereby reducing the structural complexity of the liquid containing device.

[0152] Embodiment III

[0153] Embodiment III provided by the present application is a further improvement of the above-mentioned Embodiment II, and their overall structures are relatively similar. The differences from Embodiment II will be introduced in detail below.

[0154] As Figure 10As shown, the projection of the connecting member 11 on the bottom plate 21 can be set as a trapezoid with the bottom side parallel to the front baffle 221, that is, the length of the connecting member 11 on the side facing the front baffle 221 is greater than the length of the connecting member 11 on the side facing away from the front baffle 221. The side of the connecting member 11 facing away from the front baffle 221 is the side close to the liquid container 12. Specifically, the side of the connecting member 11 close to the front baffle 221 is wider and can be set in size to abut against the side baffle 223, thereby ensuring the installation stability, and its two sides do not contact the convex portion 23, and there will be no interference with the convex portion 23 during the installation process, which can improve the convenience of the installation process. In addition, the width of the part of the connecting member 11 far from the front baffle 221 is significantly narrowed, and its two sides can serve as the acting points for the user to grasp and place the liquid container 12, and the liquid container 12 can be exempted from being provided with a handle member.

[0155] In addition, as shown in Figures 11 - 12 a guiding groove 214 cooperating with the locking portion 54 is provided at the bottom of the bottom plate 21. A guiding inclined surface 115 is provided on the bottom of the connecting member 11 on the side close to the front baffle 221 (the guiding inclined surface 115 is also provided in the second embodiment, and the local contour of the corresponding part of the connecting member can be referred to Figure 8 for understanding). There is a gap between the connecting member 11 and the wedge-shaped convex portion 213 at the guiding inclined surface 115. In this embodiment, a plurality of ribs are densely arranged at the bottom of the connecting member 11. The bottom surfaces of the ribs on the side of the bottom of the connecting member 11 close to the front baffle 221 are inclined and flush, so the guiding inclined surface 115 is actually the bottom surfaces of these ribs and can be understood as a set of discontinuous narrow surfaces. Figures 13 - 14 shows the specific structure of the limiting member 152 and the specific connection relationship between the passing-out portion and the engaging portion in this embodiment.

[0156] When the liquid container 12 is installed, the end of the connecting member 11 provided with the liquid outlet portion 111 can be first abutted against the front baffle 221 and abutted against the front baffle 221 at the guiding inclined surface 115. The liquid container 12 can then slide into the interior of the housing 20 along the guiding inclined surface and be clamped with the bottom plate 21. The guiding inclined surface can ensure that the sliding and assembling process of the liquid container 12 is smooth without jamming.

[0157] In addition, the housing 20 corresponding to this embodiment is also different in structure from the second embodiment. Specifically, the two convex portions 23 on its bottom plate 21 are provided at both ends of the bottom plate 21 in the X direction, and the outer sides of the convex portions 23 are fused with the side baffle 223.

[0158] Embodiment Four

[0159] See Figure 4 and Figures 15 - 16, the housing 20 adopted in this embodiment is exactly the same as that in the first embodiment. The main difference between the liquid containing device 10 involved and the first embodiment lies in the restricting member. The restricting member in this embodiment is represented by the second restricting member 153.

[0160] Referring to Figure 4 and Figure 16 As shown, when the liquid containing device is placed in the housing 20, along the second direction (X-axis), the second restricting member 153 abuts against the housing 20 to limit the liquid containing device, thereby improving the connection stability between the liquid containing device and the housing 20, and further improving the contact stability between the chip on the liquid containing device and the electrical connection part of the printer.

[0161] Among them, both ends of the second restricting member 153 in the second direction abut against the corresponding side baffle 223, so as to limit the liquid containing device at least in the second direction, and the limiting is convenient and stable.

[0162] Continuing to refer to Figure 15 and Figure 16 As shown, the second restricting member 153 can be arranged on the connecting member 11. Since the chip is arranged on the connecting member 11, by also arranging the second restricting member 153 on the connecting member 11, the stability of the connecting member 11 is directly improved, and further the contact stability between the chip 14 and the electrical connection part is improved.

[0163] Specifically, the second restricting member 153 can be arranged at the rear end of the connecting member 11 in the first direction, that is, on the side of the connecting member 11 close to the rear baffle 222. Such an arrangement is convenient for assembly.

[0164] Referring to Figure 4 and Figure 16 As shown, there is a cut-off surface 227 on the inner wall of the housing. The rear end of the second restricting member in the first direction abuts against the cut-off surface 227, so as to at least prevent the liquid containing device from moving in the -Y direction to a certain extent, and further improve the connection stability between the liquid containing device and the housing 20.

[0165] Specifically, the front end of the side edge 224 can form the cut-off surface 227. In this way, the side edge 224 not only plays a role in strengthening the structural strength of the housing, but also plays a role in limiting the liquid containing device at the same time. Of course, a positioning protrusion or other structures can also be arranged in the housing, and the end face of the positioning protrusion facing the connecting member 11 forms the above-mentioned cut-off surface.

[0166] Combined with Figure 4 and Figure 16 As shown, in the X-axis direction, on the side of each end of the second restricting member 153 away from the connecting member 11, it abuts against a side edge 224 at the cut-off surface 227. This can further improve the stability and balance of the liquid containing device.

[0167] Among them, the distance from the cut-off surface 227 to the front baffle 221 is greater than the distance from the convex part 23 to the front baffle 221. Such a setting makes the assembly more convenient.

[0168] The connecting component 11 includes a front part 113 close to the front baffle 221 and a transition part 114 close to the rear baffle 222. The liquid outlet part 111 and the chip 14 are located on the front part 113, and the second limiting part 153 is arranged on one side of the transition part 114 close to the rear baffle 222.

[0169] In the X-axis direction, the transition part 114 is located between the two convex parts 23. In this way, the two convex parts 23 can limit the connecting component 11 in the second direction (X-axis) to a certain extent, and further improve the stability of the liquid containing device.

[0170] The length of the transition part 114 is less than the length of the front part 113, and the length of the second limiting part 153 is greater than the length of the front part 113. By making the sizes of each part different, it can play an effect of assembly guidance to a certain extent and improve the assembly efficiency.

[0171] At least part of the bottom surface of the second limiting part 153 is attached to the upper surface of the bottom plate 21. In this way, the bottom plate 21 can support the second limiting part 153, and at the same time, limit the liquid containing device in the Z direction, further improving the stability of the liquid containing device relative to the housing 20.

[0172] The thickness of the second limiting part 153 is less than the thickness of the connecting component 11. In this way, while achieving a good limiting effect of the second limiting part 153, it can prevent the situation that the second limiting part 153 is too thick and causes the whole liquid containing device to be too thick, which is beneficial to the development of the whole device towards a smaller volume.

[0173] A recessed part 153a for avoiding the liquid containing body 12 is centrally arranged on the second limiting part 153. By means of the recessed part 153a, the interference of the second limiting part 153 on the liquid containing body 12 can be reduced.

[0174] Among them, the thickness of the recessed part 153a is less than or equal to the thickness of the second limiting part 153.

[0175] Among them, the length of the recessed part 153a in the X-axis direction is less than the side length of the transition part 114 on the side close to the rear baffle 222. Such a setting can ensure the self-structural strength of the second limiting part 153.

[0176] In addition, a guiding inclined surface 115 is provided on one side of the bottom of the connecting component 11 close to the front baffle 221. The guiding inclined surface 115 can guide the liquid containing device during the process of installing the liquid containing device into the housing 20, improving the assembly efficiency.

[0177] The introduction of the recess 153a can reduce the interference of the second limiting member 153 with the liquid containing body 12. Exemplarily, the thickness of the recess 153a in the Z-axis direction is equal to the thickness of the second limiting member 153 in the Z-axis direction, and the second limiting member 153 is disconnected at the recess 153a, which can effectively avoid the liquid containing body 12. It should be noted that in this embodiment, the aforementioned lengths all refer to the dimensions along the X-axis direction, and the thickness refers to the dimension along the Z-axis direction.

[0178] The outer end (i.e., the front end along the first direction) of the liquid outlet part 111 and the two ends of the second limiting member 153 form a triangular arrangement, and are all directly connected to the outer frame 22, which can ensure the stable assembly of the whole liquid containing device 10 in the housing 20, and further improve the contact stability between the chip 14 and the printer electrical connection part 52.

[0179] The liquid outlet part 111 can also play a role of guiding and positioning during the installation process.

[0180] Among them, as shown in Figure 2 、 Figure 3 、 Figure 15 and Figure 16 , the liquid outlet part 111 passes through the front baffle 221 through the first through notch 225, and the liquid outlet part 111 abuts against both sides of the first through notch 225, and the two ends of the second limiting member 153 abut against both sides of the housing 20, so that the outer end of the liquid outlet part 111 and the two ends of the second limiting member 153 along the second direction form a stable triangular arrangement. And because the outer end of the liquid outlet part 111 and the two ends of the second limiting member 153 are both in contact with the housing 20, the connection stability between the whole liquid containing device and the housing 20 is further improved, and further the contact stability between the chip 14 and the printer electrical connection part is improved. The force received by the liquid containing device 10 can act on the whole outer frame 22, which can prevent the stress of the housing 20 from being overly concentrated, and effectively inhibit the structural damage and deterioration of the housing 20 at the connection part with the liquid containing device 10.
