Description

Technical Field

[0001] This utility model belongs to the field of printing device technology, and particularly relates to an ink cartridge and an ink cartridge mounting assembly consisting of the ink cartridge and an ink cartridge mounting part. Background Technology

[0002] Existing patent CN104118216A discloses an ink cartridge having a locking track and a locking fixing part that engage with a movable locking latch in a printer ink cartridge mounting part. The ink cartridge mounting part also has an elastic member acting on the ink cartridge. During ink cartridge installation, the ink cartridge compresses forward against the elastic member, the locking track guides the locking latch to a predetermined position, and then the elastic member rebounds, causing the locking latch to engage with the locking fixing part, thereby securing the ink cartridge in the ink cartridge mounting part and achieving connection.

[0003] However, in the above connection methods, there may be cases where the locking track fails to guide the locking mechanism to the predetermined position. As a result, when the ink cartridge is subjected to the rebound force of the elastic component, the locking mechanism fails to engage with the locking fixing part, ultimately leading to ink cartridge installation failure and a poor user experience.

[0004] Specifically, in combination Figures 1 to 3 As shown, the prior art discloses a printer cartridge mounting part 2 and a compatible cartridge 3. The cartridge mounting part 2 includes a movable latch 21 and an elastic member 22. The cartridge 3 includes a latch track 31 and a latch fixing part 32 that cooperate with the movable latch 21 in the cartridge mounting part 2. During cartridge installation, the user operates the cartridge 3 to push it forward and compress the elastic member 22. The latch track 31 guides the latch 21 to a predetermined position 33. Then, through the rebound of the elastic member 22, the latch 21 engages with the latch fixing part 32, thereby fixing the cartridge 3 in the cartridge mounting part 2 and achieving connection.

[0005] However, in the above connection method, there may be situations where the locking track 31 fails to successfully guide the locking buckle 21 to the predetermined position 33. For example, when the user pushes the ink cartridge 3, when the locking buckle 21 is guided to the corner position 34, the locking buckle 21 will encounter resistance at a certain point of the corner position 34, causing the user to mistakenly believe that it has reached the designated position 33 and release it. After releasing, since the locking buckle has not yet reached the predetermined position 33, the ink cartridge 3 is subjected to the rebound force of the elastic component 22, which will cause the locking buckle 21 to retract from the locking track 31 along the original path and fail to engage with the locking fixing part 32, ultimately resulting in the failure of ink cartridge 3 installation. The user needs to repeatedly push the ink cartridge to try to install it until the locking buckle 21 engages with the locking fixing part 32 successfully. This method will result in a poor user experience. Utility Model Content

[0025] To better understand the technical solution of this utility model, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] The terminology used in the embodiments of this utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0027] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this utility model are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model.

[0028] See Figure 5 This utility model provides an ink cartridge 1, which includes an ink cartridge body 11. The ink cartridge body 11 includes a front wall 111, a rear wall 112, a top wall 113, a bottom wall 114, a left wall (not shown in the figure), and a right wall (not shown in the figure). The front wall 111, rear wall 112, top wall 113, bottom wall 114, left wall, and right wall together form a receiving cavity 117. The ink cartridge body 11 is provided with a mounting structure. The ink cartridge 1 is used to mount such as Figure 1 , Figure 3 and Figure 4 The printer shown has an ink cartridge mounting section 2, which includes a movable latch 21, an elastic member 22, and an abutment portion 23 located on the lower wall of the inner cavity of the ink cartridge mounting section 2. During installation, the front wall 111 enters the ink cartridge mounting section 2 first.

[0029] Figure 4 As can be seen, the ink cartridge mounting section 2 also includes: a gas channel connection section 26 for connecting the ink cartridge gas channel and supplying gas to the inside of the ink cartridge; an ink outlet connection section 27 for connecting the ink cartridge ink outlet; an ink cartridge mounting slot 28; a latch 21; and a rib 24, etc. These components are all part of the original printer configuration, and the ink cartridge in this embodiment is used to adapt to this type of printer.

[0030] Regarding the receiving cavity 117: In one embodiment, the receiving cavity 117 can be used to directly store ink; in another embodiment, the receiving cavity 117 can be used to accommodate an ink bag containing ink.

[0031] Regarding the installation structure, the details are as follows:

[0032] The front wall 111 of the ink cartridge body 11 is provided with a groove serving as a clearance part 12, which is used to accommodate the elastic member 22 in the ink cartridge mounting part 2. During the installation and pushing of the ink cartridge 1, since the clearance part 12 can accommodate the elastic member 22, the elastic member 22 is not compressed. After the user releases his / her hand, the ink cartridge 1 will not be ejected due to the rebound force of the elastic member 22.

[0033] The front wall 111 of the ink cartridge body 11 is also provided with an ink outlet channel 14 that connects to the receiving cavity 117. The ink outlet channel 14 is located below the clearance part 12 and is used to output the ink in the receiving cavity 117 to the printing device.

[0034] The bottom wall 114 and the right wall of the ink cartridge body 11 are provided with an outward and downward protruding abutment 13 at the edge where they meet. During the ink cartridge installation process, the abutment 13 cooperates with the abutted part 23 in the ink cartridge installation part 2.

[0035] Furthermore, continue to combine Figure 4As shown, the ink cartridge 1 also includes a gas channel 15, which is located inside the clearance portion 12 and connects the inside and outside of the receiving cavity 117. During ink cartridge operation, air is supplied to the receiving cavity 117 through the gas channel 15 to ensure constant pressure inside the ink cartridge. An abutment member 13 is disposed on the bottom wall 114 of the ink cartridge body 11 for an interference fit with the abutted portion 23. The gas channel 15 is configured not to obstruct the resilient member 22 from being received by the clearance portion 12. Conventionally, the outer diameter of the gas channel 15 can be set smaller than the inner diameter of the resilient member 22, allowing the resilient member 22 to be fitted between the clearance portion 12 and the gas channel 15.

[0036] Combination Figure 6 As shown, the abutment 13 includes an installation ramp 131 and a disassembly ramp 132 disposed opposite to each other. The installation ramp 131 is closer to the front wall 111, while the disassembly ramp 132 is farther from the front wall 111. During ink cartridge installation, the abutment 13 is guided into the ink cartridge mounting part 2 by the installation ramp 131. During this process, the abutment 13 will have a proper interference fit with the abutted part 23. After the abutment 13 passes the abutted part 23, the disassembly ramp 132 engages with the abutted part 23, thereby fixing the ink cartridge 1 in the ink cartridge mounting part 2 and achieving a stable connection with the ink cartridge mounting part 2. When it is necessary to remove the ink cartridge 1, the user only needs to pull the ink cartridge 1 out in the opposite direction of the installation direction. During the pulling process, under the pull of the user, the disassembly ramp 132 guides the abutment 13 to disengage from the abutted part 23. During this process, the abutment 13 will also have a proper interference fit with the abutted part 23.

[0037] In some embodiments, the abutment is disposed on the top wall 113 of the ink cartridge body 11, and correspondingly, the abutted portion 23 is located on the upper wall of the inner cavity of the ink cartridge mounting portion 2. In other embodiments, the abutment is disposed on both the top wall 113 and the bottom wall 114 of the ink cartridge body 11. The dimensions of the abutment 13 are designed to allow for an interference fit with the abutted portion 23. In this invention, the ink cartridge mounting portion 2 is a conventional printer structure and does not require modification. The abutted portion 23 does not require additional provision; it is actually the position on the upper and / or lower wall of the conventional inner cavity corresponding to the abutment 13.

[0038] In one embodiment of this utility model, the abutment 13 may be made of an elastic material. In another embodiment of this utility model, the abutment 13 may be integrally formed with the ink cartridge body 11, or may be detachably connected to the ink cartridge body 11; this utility model does not impose any limitations on this.

[0039] Furthermore, the ink cartridge 1 also includes a limiting member 16, which is located on the top wall 113. During the ink cartridge installation process, the limiting member 16 is used to cooperate with the rib 24 in the ink cartridge installation part 2 to prevent the ink cartridge 1 from being pushed too far by the user, which would cause the abutting member 13 to fail to cooperate with the abutting part 23.

[0040] Furthermore, the ink cartridge 1 also includes a chip mounting portion (not shown in the figure), which is located above the clearance portion 12 and is detachably connected to the ink cartridge body 11. In another embodiment, the chip mounting portion can also be integrally formed with the ink cartridge body 1. The chip mounting portion 17 includes a chip mounting bracket and a chip. The chip is used to communicate with the printer to provide the printer with relevant information about the ink cartridge, such as ink color, number of ink cartridge uses, or remaining ink level.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
