[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but it is easy for those skilled in the art to understand that the present invention can also be implemented in other ways different from those described herein. Therefore, other possible implementation methods that can be known by those skilled in the art based on the embodiments described in this application all belong to the protection scope of this application.

[0057] The liquid holding container of the present invention is basically the same in structure and working principle as the liquid holding body disclosed in Patent No. CN109153267B, and the identical parts will not be described in detail. The following only focuses on the main differences between the present invention and the liquid holding body disclosed in Patent No. CN109153267B.

[0058] The liquid holding container involved in the utility model can be installed on a liquid injection device. The liquid holding container is provided with an ink outlet for conveying the liquid printing material inside the liquid injection device, and provides the liquid injection device with liquid printing material when the liquid holding container is installed on the liquid injection device.

[0059] The terminal connection structure involved in the utility model is used to be arranged on a liquid holding container. When the liquid holding container is installed on a liquid injection device, the terminal connection structure establishes an electrical connection with the device-side terminal portion 770 on the liquid injection device, and transmits and receives signals between the liquid injection device and the liquid holding container, so that the liquid injection device can obtain information about the liquid holding container, such as whether the liquid holding container is installed, the specifications of the liquid holding container, and other information.

[0060] like Figure 2The liquid ejection device includes a liquid supply unit 50 for mounting a liquid container, and the liquid supply unit 50 includes a device-side terminal unit 770 and an ink receiving port 51. When the liquid container is mounted on the liquid supply unit 50, the device-side terminal unit 770 is electrically connected to the container-side terminal, and the ink receiving port 51 is connected to the ink outlet. Further, the liquid supply unit 50 also includes a positioned portion 53S located on the +X direction side, and the positioned portion 53S is used to cooperate with the liquid container so that the liquid container is positioned.

[0061] For ease of description, the liquid holding container is first defined as follows: the liquid holding container uses three mutually orthogonal spatial axes as the X-axis, Y-axis, and Z-axis, and uses the directions along the X-axis, Y-axis, and Z-axis as the X-axis direction, Y-axis direction, and Z-axis direction, respectively; the positive directions along the X-axis, Y-axis, and Z-axis are respectively the +X-axis direction, +Y-axis direction, and +Z-axis direction, and the negative directions along the X-axis, Y-axis, and Z-axis are respectively the -X-axis direction, -Y-axis direction, and -Z-axis direction; when the liquid holding container is installed to the liquid injection device, the liquid holding container is installed to the liquid supply portion 50 from the +Y direction side to the -Y direction side, facing the front wall of the liquid supply portion 50 on the -Y direction side.

[0062] The device-side terminal portion 770 includes a terminal mounting portion 771, a device-side terminal group and a positioning portion disposed on the terminal mounting portion 771. The terminal mounting portion 771 has a storage space for accommodating the device-side terminal group, the storage space is open toward the angle between the -Y direction side and the -Z direction side, and the device-side terminal group is disposed in the storage space; the device-side terminal group is configured to face obliquely downward in a manner such that the normal vector of its surface has a vector component on the +Y direction side and a vector component on the -Z direction side, the device-side terminal group includes a plurality of contacts 772a disposed at intervals and a contact portion 772b disposed on the contact 772a, the contact portion 772b is used to electrically connect to the container-side terminal, and the contact portion 772b extends from the contact 772a in a direction away from the terminal mounting portion 771, and the device-side terminal portion 770 also includes a plurality of partition plates (not shown), the plurality of contacts 772a are spaced apart along the X-axis direction, there is a gap between the plurality of contacts 772a, and each two adjacent contacts 772a are separated by a partition plate.

[0063] Among them, the device side terminal group forms a process groove 776 at one end close to the +Y direction side and the inner wall of the +Z direction side of the accommodating space; and a positioning portion, the positioning portion includes a first positioning portion 773a and a second positioning portion 773b, and the first positioning portion 773a and the second positioning portion 773b are respectively arranged on the side wall on the +X direction side and the side wall on the -X direction side of the opening of the terminal mounting portion 771.

[0064] Specifically, see Figure 1A and Figure 1B , and also includes a connecting mechanism 774 for installing the device-side terminal portion 770 on the liquid injection device, and the device-side terminal portion 770 is installed to be able to move slightly in the X-axis and Z-axis directions relative to the liquid supply portion 50. More specifically, a T-shaped groove with an opening toward the -Z direction side is formed on the connecting mechanism 774, and the terminal mounting portion 771 is provided with a first guide protrusion 775a and a second guide protrusion 775b at one end close to the +Z direction side, and the first guide protrusion 775a and the second guide protrusion 775b are respectively arranged on the side wall of the terminal mounting portion 771 on the +X direction side and the side wall on the -X direction side; wherein, when the device-side terminal portion 770 is mounted on the connecting mechanism 774, the lengths of the first guide protrusion 775a and the second guide protrusion 775b in the X-axis direction and the Z-axis direction are both smaller than the lengths of the T-shaped groove in the X-axis direction and the Z-axis direction, that is, the terminal mounting portion 771 and the connecting mechanism 774 have a small gap in the X-axis direction and the Z-axis direction, so that the device-side terminal portion 770 is installed to be able to move slightly in the X-axis and Z-axis directions relative to the liquid supply portion 50.

[0065] [Example 1]

[0066] like Figure 1A , Figure 1B , Figure 2-5B This embodiment provides a terminal connection structure and a liquid holding container having the terminal connection structure. The terminal connection structure can be arranged in a liquid holding container for holding liquid printing materials, and can be installed together with the liquid holding container to a liquid ejecting device. When the terminal connection structure is installed on the liquid ejecting device, the device-side terminal portion 770 can move in a direction intersecting with the installation direction in which the liquid holding container is installed. For ease of description, the liquid holding container having the terminal connection structure is described below.

[0067] The liquid storage container includes the above-mentioned terminal connection structure, and the liquid storage container includes a liquid storage portion 710 for storing liquid, a supply component 720 (such as Fig. 12CAs shown) and an adapter 730, the supply component 720 is connected to the liquid receiving portion 710, and has a supply channel 723 for supplying the liquid in the liquid receiving portion 710 to the liquid injection device side, and the supply channel 723 can be connected to the ink receiving port 51 on the liquid supply portion 50; the terminal connection structure is arranged on the adapter 730, the adapter 730 is connected to the liquid receiving portion 710, and the adapter 730 is provided with an ink outlet 731 corresponding to the supply channel 723. When the liquid holding container is installed on the liquid injection device, the liquid in the liquid receiving portion 710 enters the liquid injection device through the supply channel 723 and the ink outlet 731 in sequence. Among them, the adapter 730 and the liquid receiving portion 710 can be integrally or separately formed; in this embodiment, the adapter 730 and the liquid receiving portion 710 are separately formed, and the liquid receiving portion 710 is a flexible bag; in some embodiments, the terminal connection structure can also be applied to liquid receiving containers whose liquid receiving portions are rigid structures, such as ink cartridges.

[0068] The terminal connection structure includes a container-side terminal 101 that can be electrically connected to the device-side terminal portion 770, a restriction portion 102 for restricting the movement of the positioning portion in the cross direction, and a recess 103 for inserting the device-side terminal portion 770 when the device is installed in the liquid ejecting device. Specifically, the container-side terminal 101 is arranged so as to face obliquely upward in a manner such that the normal vector of the surface thereof has a vector component in the -Y direction and a vector component in the +Z direction.

[0069] Specifically, Figure 5A As shown, the recess 103 includes an opening provided along a plane orthogonal to the Y axis and an opening provided along a plane orthogonal to the Z axis. In addition, the inner wall of the recess 103 is generally composed of a pair of side walls (902t, 902w), a bottom wall 901, and a rear wall 903. The space formed in the recess 103 by the side walls 902, the bottom wall 901, and the rear wall 903 is used for inserting the device-side terminal portion 770. The recess 103 is a roughly hexahedron composed of the opening 911, the opening 912, the pair of side walls 902t, 902w, the bottom wall 901, and the rear wall 903 as main surfaces.

[0070] When the device side terminal portion 770 enters the recess 103, the first positioning portion 773a or the terminal mounting portion 771 is used to set the side wall of the first positioning portion 773a to abut against the side wall 902w, and / or the second positioning portion 773b or the terminal mounting portion 771 is used to set the side wall of the second positioning portion 773b to abut against the side wall 902t.

[0071] Among them, Figure 5A and 5BThe container-side terminal 101 is arranged in an area outside the recess 103; the limiting portion 102 is arranged in the recess 103 or above the recess 103, and the limiting portion 102 has a limiting end portion 102a that can be inserted into the process groove 776; when the terminal connection structure is installed in the liquid supply portion 50, the limiting end portion 102a is inserted into and abuts against the process groove 776 to limit the movement of the device-side terminal portion 770 in the cross direction.

[0072] Specifically, the recess 103 is arranged on the +Y direction side of the container side terminal 101, and the recess 103 is on the +Z direction side of the container side terminal 101; in the present embodiment, the limiting portion 102 is formed by extending from the rear wall 903 to the -Y direction side, the plane in which the limiting portion 102 is located is orthogonal to the Z axis, and the length direction of the limiting portion 102 is parallel to the X axis direction.

[0073] Furthermore, in this embodiment, the ink outlet 731 is arranged at the middle position of the front side of the adapter 730 close to the liquid supply part 50, and the terminal connection structure is arranged on the -X direction side of the ink outlet 731; further, there is a gap between the side wall 902w and the rear wall 903.

[0074] [Example 2]

[0075] like Figure 6 As shown, this embodiment provides a terminal connection structure and a liquid holding container having the terminal connection structure, which differs from Embodiment 1 in that an opening is provided between the rear wall 903 and the side wall 902t of the recess 203, and a reinforcing rib 204 is provided between the limiting portion 202 and the bottom wall 901. At this time, the rear wall 903 is the side surface of the reinforcing rib 204 on the -Y direction side.

[0076] [Example 3]

[0077] like Figure 7 As shown, this embodiment provides a terminal connection structure and a liquid storage container having the terminal connection structure, which is different from the first embodiment in that the structure of the recess is different.

[0078] The recess 303 also includes a side opening facing the -X axis direction, and the side opening is located on the -X direction side of the recess 303. Therefore, the recess 303 has only one side wall 902w; the adapter 730 is provided with an ink outlet side wall on the +X direction side of the recess 330, and the ink outlet side wall is integrally formed with the side wall 902w; the limiting portion 302 is arranged at one end of the rear wall 903 close to the -X axis side. When the device side terminal portion 770 is inserted into the recess 303, the end of the limiting portion 302 on the -X axis side abuts against the end of the process groove 776 on the -X axis side, and at the same time, the first positioning portion 773a abuts against the ink outlet side wall. Furthermore, it can also be arranged that the side wall of the device side terminal portion 770 on the +X direction side abuts against the side wall 902t of the recess 303.

[0079] [Example 4]

[0080] like Fig. 8A and Figure 8B This embodiment provides a terminal connection structure and a liquid holding container having the terminal connection structure, which is different from Embodiment 3 in that the limiting portion 402 further includes a limiting protrusion 402b.

[0081] The limiting end 402a is also provided with at least one limiting protrusion 402b on the -Z direction side, and the limiting protrusion 402b is set corresponding to the gap between the contacts 772a of the device side terminal portion 770, and the width of the limiting protrusion 402b in the X-axis direction matches the width of the gap between the contacts 772a; when the device side terminal portion 770 is inserted into the recess 403, the limiting end 402a is inserted into the process groove 776, and the limiting protrusion 402b is inserted into the gap between the contacts 772a.

[0082] Furthermore, more than two limiting protrusions 402b may be provided. In this embodiment, Figure 1A As shown, the device side terminal group includes 9 contacts 772a, and the contacts 772a are staggered on a surface inclined in a direction including a +Y-axis direction component and the -Z-axis direction component. When observed in a direction orthogonal to the inclined surface, 4 of the contacts 772a are located on the +Z direction side of the other 5 contacts 772a.

[0083] It should be noted that the gap may also be a gap formed between the contact 772 a and the inner wall of the terminal mounting portion 771 on the +X direction side and the inner wall on the −X direction side.

[0084] It should be noted that when the number of limiting protrusions 402b is more than two, the limiting protrusions 402b can be inserted into adjacent or non-adjacent gaps between the contacts 772a, and the spacing distance between the limiting protrusions 402b is not limited, as long as the limiting protrusions 402b can be inserted into the gap. In this embodiment, the number of limiting protrusions 402b is set to 3, and the limiting protrusions 402b are all located at the same position on the Z axis.

[0085] In some embodiments, when the number of the limiting protrusions 402 b is more than two, the limiting protrusions 402 b may have different positions on the Z-axis.

[0086] [Example 5]

[0087] like Figures 9A-9C This embodiment provides a terminal connection structure and a liquid storage container having the terminal connection structure, which differs from Embodiment 1 in terms of the structure of the limiting portion and the position of the limiting portion relative to the recessed portion.

[0088] The container side terminal 501 is arranged in an area outside the recess 503; the limiting portion 502 is arranged in an area outside the recess 503, and the limiting portion 502 is inclined relative to the installation direction, and the surface of the limiting portion 502 gradually approaches the +Z direction side from the -Y direction side to the +Y direction side.

[0089] During the process of inserting the device side terminal portion 770 into the recess 503 from the -Y direction side to the +Y direction side, the positioning portion generates a displacement on the +Z direction side under the guiding action of the limiting portion 502. When the device side terminal portion 770 is inserted into the recess 503 and the device side terminal portion 770 is electrically connected to the container side terminal 501, the device side terminal portion 770 is at the maximum movement limit position on the +Z direction side, that is, the surface of the terminal mounting portion 771 on the +Z direction side abuts against the inner wall of the connecting mechanism 774 on the -Z direction side. At this time, the limiting portion 502 presses the positioning portion so that the device side terminal portion 770 is pressed on the connecting mechanism 774, and the device side terminal portion 770 cannot move in the cross direction.

[0090] In some embodiments, both left and right sides of the container-side terminal 501 are provided with restriction portions.

[0091] [Example 6]

[0092] like Fig. 10A and 10B This embodiment provides a terminal connection structure and a liquid holding container having the terminal connection structure, which is different from Embodiment 5 in that the limiting portion 602 is disposed in the recess 603 .

[0093] When the device-side terminal portion 770 is inserted into the recess 603 , a portion of the contact 772 a and / or a portion of the partition plate abuts against the limiting portion 602 .

[0094] In this embodiment, the recess 603 does not have a bottom wall and a rear wall; the limiting portion 602 is an inclined surface formed in the recess 603 for abutting against the contact 772a and / or the partition plate. When the liquid holding container is installed on the liquid injection device, the inclined surface is used to push the device side terminal portion to move in the +Z direction to reduce the free displacement stroke of the device side terminal portion 770 in the Z-axis direction, or to make the device side terminal portion 770 be pressed in the Z-axis direction and be in an immovable state. That is to say, when the liquid holding container is installed on the liquid injection device, the device side terminal portion 770 can have a free displacement stroke in the Z-axis direction without affecting the electrical connection with the container side terminal 601, or it can be abutted by the inclined surface and be in an immovable state; in this way, the stability of the electrical connection between the device side terminal portion 770 and the container side terminal 601 is ensured.

[0095] [Example 7]

[0096] like Figure 11-Figure 14 The present embodiment provides a liquid holding container, which can be installed on a liquid injection device. The liquid holding container includes: a liquid receiving portion 710, which is used to receive liquid, and the liquid is a liquid printing material; a supply component 720, which is connected to the liquid receiving portion 710 and has a supply channel 723 for supplying the liquid printing material in the liquid receiving portion 710 to the liquid injection device side; an adapter 730, which is installed on the supply component 720 and is used to connect the supply channel 723 with the liquid injection device; the adapter 730 and the supply component 720 are installed by snapping.

[0097] Specifically, the supply component 720 includes a connecting seat 721, a supply member 722 and a supply tube 7221 connected to the connecting seat 721, the supply member 722 is arranged on the connecting seat 721, and in the Y-axis direction, the supply member 722 is opposite to the supply tube 7221, and the supply member 722 is arranged in the liquid receiving portion 710, and can be used to support the liquid receiving portion 710 to prevent the inner walls of the liquid receiving portion 710 from fitting together and affecting the supply of ink; the supply channel 723 is arranged on the supply member 722, and the supply tube 7221 has a supply outlet 724; the adapter 730 has an adapter space 734 for accommodating the supply tube 7221; when the supply component 720 is installed toward the adapter 730, the supply outlet 724 of the supply tube 7221 is inserted into the adapter space 734 along the -Y direction until the buckle connects the supply component 720 with the adapter 730, and at this time the supply outlet 724 is located in the ink outlet 731.

[0098] Further, in the present embodiment, the buckle comprises a first engaging portion 761 provided on the outer wall of the supply component 720 and a second engaging portion 762 provided on the adapter 730.

[0099] During the process of installing the supply component 720 to the adapter 730, a side surface of the first engaging portion 761 close to the -Y direction side abuts against the inclined surface 762a and causes the second engaging portion 762 to undergo elastic deformation. Subsequently, the first engaging portion 761 as a whole passes over the second engaging portion 762, and the second engaging portion 762 approaches toward the supply tube 7221 under the action of its own elastic force. Finally, the vertical surface 762b can abut against the surface of the first engaging portion 761 close to the +Y direction side. At this time, the supply component 720 is in a state of being installed to the adapter 730.

[0100] Furthermore, the liquid container further includes a handle 750, which is mounted on the supply member 720. Furthermore, the handle 750 is mounted on the supply member 720 via a third engaging portion 755 and a fourth engaging portion 756 that can cooperate with each other.

When the engaging member 756a is engaged with the engaging groove 755b, the engaging plate 755a is located between the connecting portion 752 and the engaging protrusion 756b. The width of the engaging member 756a in the Z-axis direction matches the width of the engaging groove 755b in the Z-axis direction, and the width of the engaging protrusion 756b in the Z-axis direction is greater than the width of the engaging groove 755b in the Z-axis direction. The engaging protrusion 756b limits the engaging member 756a from being detached from the engaging groove 755b through the engaging protrusion 756b, so that the handle 750 can be easily installed when the liquid holding container is assembled.

[0104] Furthermore, if Fig.13 and Fig.14 The liquid holding container is installed in a shell 740 on the liquid injection device in a detachable manner.

That is, in this embodiment, the container-side terminal support seat 704 is clamped with the adapter 730 from the inside of the adapter 730.

[0126] Furthermore, when it is necessary to remove the container side terminal assembly 700, the first blocking protrusion 70441 and the second blocking protrusion 70451 can be pressed simultaneously to bring the two closer to each other, thereby causing the first blocking protrusion 70441 to disengage from the abutment with the fifth plate 730d1, and the second blocking protrusion 70451 to disengage from the abutment with the sixth plate 7385, and then the container side terminal assembly 700 can be removed by moving to the -Z direction along the guide portion 7046.

[0127] like Fig.17The +Y direction side of the container side terminal assembly 700 is provided with a limiting portion 702 for abutting against the device side terminal, and the limiting portion 702 is arranged in the recess 703.

In the process of installing the liquid holding container to the shell 740, the rear positioning piece 735a is used to abut against the inner wall of the shell to play a guiding role, and at the same time, it can ensure that the adapter 730 will not shake when installed in the shell 740. Furthermore, the rear positioning piece 735a or the adapter 730 will not contact the two columnar bodies 744 (such as Fig.14 It should be noted that, in the above embodiment, the device-side terminal is pushed to the maximum movement limit position in the Z-axis direction by the limiting portion (such as 602), but in fact, the device-side terminal can also be pushed along the +Z direction by the inclined surface. Even if the device-side terminal can still shake, it is sufficient to ensure the electrical connection between the container-side terminal assembly 700 and the device-side terminal, and it is not necessary to move to the maximum movement limit position in the Z direction.

[0128] Further, the rear positioning member 735a includes an upper side 735a1 and a lower side 735a2 connected to each other, and a groove 735a3 is provided between the upper side 735a1 and the lower side 735a2 for the liquid receiving portion 710 to pass through. The upper side 735a1 and the lower side 735a2 are connected to each other to ensure structural strength. Further, the -Y direction side of the adapter 730 is provided with a front positioning member 735b. Further, in the X-axis direction, the front positioning member 735b is located at the end of the adapter 730. In this embodiment, only the +X side of the adapter 730 is provided with the front positioning member 735b. In other embodiments, the front positioning member 735b can also be provided on the +X direction side and the -X direction side of the adapter 730, respectively. The front positioning member 735b is used to abut against the bottom plate 741 so that the adapter 730 is supported by the bottom plate 741.

[0129] Furthermore, in the prior art, a sealing plug with a through hole is generally provided in the supply outlet 724. When the supply outlet 724 and the ink receiving port 51 are accurately connected, the inner wall of the through hole fits with the outer wall of the ink receiving port 51, thereby ensuring the sealing performance. When the supply outlet 724 and the ink receiving port 51 are not accurately connected, a gap will be generated between the inner wall of the through hole and the outer wall of the ink receiving port 51, thereby causing ink leakage. Compared with the prior art, in this embodiment, the front positioning member 735b can also be used to cooperate with the positioned portion 53S, and the positioned portion 53S can prevent the adapter 730 from moving in the Z-axis direction and the +X direction; at the same time, the cooperation between the supply outlet 724 and the ink receiving port 51 can also play a positioning role. In this way, two relatively balanced positioning structures are formed between the adapter 730 and the liquid injection device, so that the connection between the liquid holding container and the liquid injection device is stable, thereby avoiding ink leakage caused by gaps due to inaccurate connection between the ink receiving port 51 and the supply outlet 724.

[0130] Furthermore, when the liquid holding container is in the installed state, the container side terminal 701 located on the -X direction side of the adapter 730 is subjected to the abutment force of the device side terminal portion 770, and the front positioning piece 735b located on the +X direction side of the adapter 730 can balance the abutment force of the device side terminal portion 770, thereby making the adapter 730 more stable.

[0131] like Fig. 15B , Fig. 16C , Fig.17 and Fig.18 The supply component 720 and the adapter 730 are fixed by a fixing portion T arranged in the liquid holding container. Specifically, the adapter 730 is provided with a first hole 736, and the supply component 720 is provided with a second hole 7211. Preferably, the first hole 736 is a through hole extending in the Z-axis direction, and the second hole 7211 can be a through hole extending in the Z-axis direction or a blind hole extending in the Z-axis direction. The fixing portion T cooperates with the first hole 736 and the second hole 7211 at the same time to fix the supply component 720 and the adapter 730, wherein the fixing portion T can be a pin, a rivet, etc., and the fixing portion T can also be a connecting portion formed by melting the supply component 720 and the adapter 730.

[0132] [Example 9]

[0133] In some embodiments, the shell 740 also includes a reinforcement 746 arranged at the intersection of the main side plate 742b and the bottom plate 741. Preferably, along the X-axis direction, the two reinforcements 746 are arranged opposite to each other, each reinforcement 746 extends along the Y-axis direction, and each reinforcement 746 has a second top surface 7461 facing the +Z axis direction. Along the Z-axis direction, the first top surface 7421 is farther away from the bottom plate 741 than the second top surface 7461.

[0134] In some embodiments, each reinforcement member 746 further has a front end surface 7462 facing the -Y axis direction. When the adapter 730 abuts against the front end surface 7462, the adapter 730 can be positioned in the +Y axis direction.

[0135] In some embodiments, the column 744 protrudes from the base plate 741 toward the +Z axis direction. Along the X axis direction, the two columns 744 are spaced apart. Depending on the different types of liquid holding containers, the spacing between the two columns 744 can be set differently. Along the Y axis direction, the column 744 is at least partially located between the two reinforcement members 746.

[0136] like Fig.23A As shown, the adapter 730 includes an adapter body 7302 and a limiting portion 733, the ink outlet 731 and the limiting portion 733 are both arranged on the adapter body 7302, and the limiting portion 733 is used to cooperate with the front side plate 742a to position the liquid holding container in the Y-axis direction; further, the adapter 730 also has an adaptation space 734 (such as Fig.25B As shown), a portion of the supply component 720 can enter the adaptation space 734, so that the supply component 720 and the adapter 730 are combined.

[0137] The liquid container further includes a handle 750 , which can be mounted on any one of the supply component 720 and the adapter 730 . The user can use the handle 750 to mount and dismount the liquid container.

[0138] Furthermore, the liquid holding container involved in this embodiment further includes an auxiliary positioning member 780, which is used to assist the positioning of the liquid holding container as a whole in the housing 740, and the auxiliary positioning member 780 is used to connect with at least one of the liquid receiving portion 710 and the adapter 730, such as Fig.23A As shown, the auxiliary positioning member 780 includes a first portion 781 and a second portion 782 connected to each other, wherein the first portion 781 is used to connect to at least one of the liquid receiving portion 710 and the adapter 730, and the second portion 782 is used to abut against the main side plate 742b.

[0139] In one embodiment, the first portion 781 is connected to the liquid receiving portion 710, and the second portion 782 is in contact with the inner side surface 7422, so that the liquid holding container can be positioned in the X-axis direction. Finally, the liquid holding container is stably positioned in the storage space.

[0140] In this embodiment, the adapter 730 does not have to cooperate with the columnar body 744. Therefore, for the shell 740 suitable for liquid holding containers of different models, even if the distance between the two columns 744 is different, it does not affect the installation of the adapter 730. In other words, after the auxiliary positioning member 780 is provided, the same adapter 730 can be used for liquid holding containers of different models. The manufacturer or user of the liquid holding container only needs to replace the corresponding auxiliary positioning member 780 according to the liquid holding container model suitable for the shell 740. For the liquid holding container manufacturer, there is no need to produce a variety of adapters 730, which is conducive to reducing production costs.

[0141] In one embodiment, the auxiliary positioning member 780 may also be connected to the adapter member 730 , which can also achieve universal use of the adapter member 730 .

[0142] In one embodiment, the auxiliary positioning member 780 includes two second parts 782, and along the X-axis direction, the two second parts 782 are respectively extended from the first part 781, or in other words, the two second parts 782 are respectively protruded from the first part 781. When the auxiliary positioning member 780 is installed to the installed object (at least one of the liquid storage portion 710 and the adapter 730), at least the second part 782 protrudes from the installed object. Preferably, at least a part of the second part 782 protrudes from the X-axis direction of the installed object; the first part 781 and the second part 782 can be formed integrally or separately. Preferably, the first part 781 and the second part 782 are formed integrally. More preferably, the first part 781 has a shape adapted to the installed object, which not only allows the auxiliary positioning member 780 to be installed more stably, but also reduces the size of the liquid holding container after the auxiliary positioning member 780 is installed.

[0143] In one embodiment, the auxiliary positioning member 780 is installed in the +Z axis direction of the object to be installed. When the liquid holding container is installed in the storage space, the X-axis end of the second part 782 abuts against the inner side surface 7422; the supply component 720 is arranged in the object to be installed, and is used to supply the liquid contained in the object to be installed to the liquid injection device.

[0144] In one embodiment, when the liquid holding container is installed in the storage space, the second portion 782 also contacts the second top surface 7461 , so that the liquid holding container is also positioned in the Z-axis direction.

[0145] In this embodiment, it should be noted that when the liquid storage portion 710 is a flexible bag body, it generally includes two flexible sheets arranged in the Z-axis direction, one of which is located in the +Z-axis direction of the other flexible sheet. When the auxiliary positioning member 780 is installed in the +Z-axis direction of the liquid storage portion 710, the auxiliary positioning member 780 will be connected to the flexible sheet located in the +Z-axis direction. In this way, through the abutment between the second part 782 and the second top surface 7461, the flexible sheet located in the +Z-axis direction can be maintained by the auxiliary positioning member 780. Even if the liquid in the liquid storage portion 710 is gradually consumed, the flexible sheet in the +Z-axis direction will not approach the flexible sheet in the -Z-axis direction. In this way, a certain amount of space will always be maintained in the liquid storage portion 710, and the liquid can be smoothly supplied to the liquid injection device by the supply component 720.

[0146] In one embodiment, if Fig.24 As shown, the auxiliary positioning member 780 can also be set in the -Z axis direction of the installed object. When the liquid holding container is installed in the storage space, the X axis direction end of the second part 782 also abuts against the inner side surface 7422; compared with the auxiliary positioning member 780 being located in the +Z axis direction of the installed object, the auxiliary positioning member 780 in this embodiment is less likely to fall off; the reason is that during the installation process of the liquid holding container, the liquid holding container may not be aligned with the corresponding position of the storage space. At this time, the installed object has entered the storage space, but the auxiliary positioning member 780 abuts against the first top surface 7421 and interferes, which may cause the auxiliary positioning member 780 to fall off from the installed object. In this embodiment, when the liquid holding container may not be aligned with the corresponding position of the storage space, the auxiliary positioning member 780 will abut against the first top surface 7421 before the installed object. At this time, the auxiliary positioning member 780 and the installed object will be more tightly combined, and the auxiliary positioning member 780 will not fall off.

[0147] In some embodiments, the liquid holding container also includes a container-side terminal assembly 700 disposed on the adapter body 7302. When the liquid holding container is installed to the liquid injection device along with the shell, the container-side terminal assembly is used to electrically connect to the device-side terminal portion in the liquid injection device, thereby enabling the liquid injection device and the liquid holding container to transmit and receive signals.

[0148] Preferably, the auxiliary positioning member 780 is detachably connected to the object to be installed.

[0149] It is feasible that the auxiliary positioning member 780 and the object to be installed can be connected by bonding, welding, snapping, magnetic connection, etc., and the present invention does not impose any limitation on this.

[0150] [Example 10]

[0151] Different from the ninth embodiment, this embodiment provides another structure for positioning the liquid holding container along the X-axis direction.

[0152] like Fig.25A and Fig.25B As shown, the handle 750 includes a gripping portion 751, a connecting portion 752 and a fourth snap-fit ​​portion 756. The gripping portion 751 is used for a user to grip to operate the liquid holding container. The connecting portion 752 is connected to the gripping portion 751. The fourth snap-fit ​​portion 756 is arranged at one end of the connecting portion 752 away from the gripping portion 751. Through the fourth snap-fit ​​portion 756, the handle 750 can be connected to the supply component 720 or the adapter 730.

[0153] Furthermore, the holding portion 751, the connecting portion 752 and the fourth snap-fitting portion 756 form a handle body, and the handle 750 also includes an extension portion 759 for abutting against the columnar body 744. The extension portion 759 can be extended from at least one of the holding portion 751, the connecting portion 752 and the fourth snap-fitting portion 756, and thus, the extension portion 759 can be regarded as extending from the handle body.

[0154] In one embodiment, at least a portion of the abutting surface of the extension portion 759 for abutting against the columnar body 744 is a curved surface, so that the extension portion 759 and the columnar body 744 can abut more tightly.

[0155] In one embodiment, the cross-section of the column 744 (along a plane perpendicular to the Z direction) is non-circular, for example, the cross-section is D-shaped. In this case, the cross-section is formed by an arc and straight lines connecting the two ends of the arc. In this embodiment, the abutment surface includes an arc surface and a plane connected to each other, which can make the adapter 730 and the column 744 abut more stably.

[0156] In one embodiment, the -Z direction surface of the extension portion 759 is set as an inclined surface, so that when the liquid holding container is installed toward the housing 740, the liquid holding container can be installed more smoothly under the guidance of the inclined surface.

[0157] The adapter 730 also includes a rear positioning member 735a. In one embodiment, during the process of installing the liquid holding container to the shell 740, the rear positioning member 735a is used to abut against the inner wall of the shell to guide the liquid holding container, while ensuring that the adapter 730 does not shake in the shell 740; the rear positioning member 735a is connected to the adapter body 7302. Preferably, the rear positioning member 735a is formed integrally with the adapter body 7302.

[0158] like Fig.25BAs shown, the rear positioning member 735a is provided with a first matching portion 735a3, and the adapter body 7302 is provided with a second matching portion 7303. The extension portion 759 is matched with at least one of the first matching portion 735a3 and the second matching portion 7303. Through at least one of the first matching portion 735a3 and the second matching portion 7303, the extension portion 759 can abut against the columnar body 744, so that the liquid holding container can be positioned in the X-axis direction.

[0159] In one embodiment, at least the second matching portion 7303 penetrates in the X-axis direction, and at least a portion of the first matching portion 735a3 extends along the X-axis direction, so that the extension portion 759 can smoothly enter the first matching portion 735a3. Preferably, the first matching portion 735a3 is also configured to penetrate in a direction intersecting the Z-axis direction. More preferably, the first matching portion 735a3 and the second matching portion 7303 are connected, so that the extension portion 759 can smoothly reach the second matching portion 7303 from the first matching portion 735a3; along the X-axis direction, at least a portion of the second matching portion 7303 is opposite to the columnar body 744.

[0160] As described above, the liquid holding container involved in this embodiment realizes the positioning of the liquid holding container in the X-axis direction by abutting the extension part 759 with the columnar body 744. Preferably, the extension part 759 is arranged on the handle 750, and the handle 750 is detachably connected to the adapter 730. In this way, the liquid holding container manufacturer only needs to produce handles 750 with different sizes or shapes, and the adapter 730 only needs to be produced in one type. The user can use the extension part 759 with different sizes or shapes according to different types of liquid holding containers, so that the adapter 730 can use a universal one.

[0161] Accordingly, the extension portion 759 in this embodiment can also be regarded as an auxiliary positioning member, and the installed object also includes a handle 759, and the extension portion 759 and the handle body can be formed in one piece or can be separately arranged.

[0162]

Other instructions

[0163] As described above, when the liquid container of the present invention is mounted on the housing 740, both sides of the liquid container in the X-axis direction can be positioned by the auxiliary positioning member 780. The auxiliary positioning member 780 has the following embodiments.

[0164] like Fig.11 , Fig.13 and Fig.14As shown, the auxiliary positioning member 780 is a guide portion 732 arranged on the adapter 730, and the guide portion 732 is used to abut against the shell 740, so that the liquid holding container can be positioned on both sides of the X-axis direction. Specifically, the guide portion 732 enters the avoidance opening 743 and abuts against the front side plates 742a on both sides of the avoidance opening 743 in the X-axis direction. More specifically, the front side plates 742a are formed into two spaced apart along the X-axis direction, and the avoidance opening 743 is located between the two front side plates 742a. ​​The two front side plates 742a are arranged opposite to each other in the X-axis direction and have a relative surface 742a1 facing the X-axis direction, and the guide portion 732 is used to abut against the relative surface 742a1.

[0165] As another embodiment of the auxiliary positioning member 780, the auxiliary positioning member 780 is a protrusion 7301 (such as Fig. 15C As shown), the protrusion 7301 is used to cooperate with the avoidance groove 745, so that the adapter 730 is positioned.

[0166] As another embodiment of the auxiliary positioning member 780, Fig.23A and Fig.24 As shown, the housing 740 further includes a guide protrusion 747 (such as Fig.23A , Fig.24 As shown, it is equivalent to the convex portion 210 of Chinese patent CN112009108B, and the adapter 730 is provided with a side surface 7303 (such as Fig.21 As shown), the auxiliary positioning member 780 is a component provided with the side end surface 7303.

[0167] The guide protrusion 747 has a slope 7471 for guiding the liquid holding container. When the liquid holding container enters the storage space, the liquid holding container is guided by the slope 7471 and smoothly reaches the installation position. Preferably, along the Y-axis direction, one of the front side plates 742a overlaps with at least a portion of the guide protrusion 747, so that the adapter 730 can be more stably positioned in the installation position.
