Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0025] Combination Figure 2 As shown, a prior art printer includes, for example... Figure 2 The ink cartridge mounting part 2 shown allows for the detachable installation of ink cartridges. The ink cartridge mounting part 2 has multiple mounting cavities 21, each used to mount ink cartridges of different colors. In this embodiment, the ink cartridge mounting part 2 includes four mounting cavities 21 for mounting ink cartridges containing magenta, yellow, cyan, and black inks. Each mounting cavity 21 of the ink cartridge mounting part 2 includes a contact pin 22, an air guide 23, a rib 24, and an ink supply needle 25. These components are sequentially arranged within the mounting cavity 21 in the direction of gravity. Each mounting cavity 21 contains two opposing ribs 24 in a horizontal direction perpendicular to the direction of gravity.
[0026] This utility model provides a structure for a printer ink cartridge with stable connection, as shown in the following example. Figure 1 As shown, the ink cartridge includes an ink cartridge body 1. The ink cartridge body 1 includes a limiting part 107, a front wall 101 facing the ink cartridge mounting direction, a rear wall 102 opposite to the front wall, a first side wall 103 and a second side wall 104 disposed between the front wall 101 and the rear wall 102, and a top wall 105 and a bottom wall 106 disposed between the front wall 101 and the rear wall 102. The ink cartridge body 1 also includes a chip 108, which is disposed on the top wall 105 near the front wall 101. The chip 108 is used to connect with the contact pin 22 of the ink cartridge mounting part 2. The chip 108 can store information related to the ink cartridge, such as batch number, manufacturing date, ink color, etc.
[0027] Furthermore, in this embodiment, the ink cartridge body 1 also includes an ink supply section 109, which is disposed on the side of the bottom wall 106 near the front wall 101. The ink supply section 109 communicates with the ink cartridge body 1 and is combined with... Figure 4 As shown, the ink supply unit 109 includes an ink supply port 1091 and a spring valve 1092. When the ink cartridge is not installed, the spring valve 1092 seals the ink supply port 1091 of the ink supply unit 109, so the ink in the ink cartridge will not leak when not in use. When the ink cartridge is installed into the ink cartridge mounting unit 2, the ink supply needle 25 of the ink cartridge mounting unit 2 is inserted into the ink supply unit 109, so that the spring valve 1092 is opened to deliver the ink in the ink cartridge for printing to the printing device.
[0028] Furthermore, in this embodiment, a limiting part 107 is provided on the first sidewall 103 and / or the second sidewall 104. The limiting part 107 is used to cooperate with the protruding rib 24, so that the position of the ink cartridge in the height direction parallel to the direction of gravity can be determined during the installation of the ink cartridge to the ink cartridge mounting part 2. In one embodiment, combined with Figure 3As shown, a first limiting part 1071 is provided on the first sidewall 103, and a second limiting part 1072 is provided on the second sidewall 104. The first limiting part 1071 and the second limiting part 1072 are protrusions. In the horizontal direction perpendicular to the direction of gravity, the projection of the first limiting part 1071 is misaligned with the projection of the second limiting part 1072. That is, the first limiting part 1071 and the second limiting part 1072 are not at the same height in the height direction. In the height direction, the distance between the first limiting part 1071 and the second limiting part 1072 is the length of the protruding rib 24 in the height direction. During the ink cartridge installation process, the first limiting part 1071 mates with the upper surface of the protruding rib 24, and the second limiting part 1072 mates with the lower surface of the protruding rib 24, so that the position of the ink cartridge in the height direction can be determined. Through this design, multiple sets of limiting parts are not required in the height direction of one sidewall, saving manufacturing costs and reducing process difficulty. In another embodiment, a first limiting part 1071 and a second limiting part 1072 may be provided on the first sidewall 103, or the first limiting part 1071 and the second limiting part 1072 may be provided on the second sidewall 104. During the ink cartridge installation process, the first limiting part 1071 cooperates with the upper surface of the protruding rib 24, and the second limiting part 1072 cooperates with the lower surface of the protruding rib 24, so that the position of the ink cartridge in the height direction can be determined.
[0029] This application provides a limiting part 107 on the first side wall 103 and / or the second side wall 104 of the ink cartridge body 1, which cooperates with the protruding rib 24 of the ink cartridge mounting part 2. This allows the position of the ink cartridge in the height direction to be determined during installation, avoiding the possibility of deviation in the position and height of the ink cartridge installed in the ink cartridge mounting part 2 each time by the user, and improving the connection stability between the ink cartridge chip and the contact pin.
[0030] Furthermore, in this embodiment, the ink cartridge body 1 also includes a gas exchange section 110, which is disposed on the ink cartridge body 1 and extends from the front wall 101 to the rear wall 102 of the ink cartridge body 1. During ink cartridge installation, the gas exchange section 110 is connected to the air guide section 23 in the ink cartridge mounting section to introduce external air to replenish the space reduced due to ink consumption, thereby maintaining the pressure balance inside the ink cartridge body 1 and ensuring that the ink can flow out smoothly for printing.
[0031] Furthermore, in this embodiment, along the direction facing the first sidewall 103, the end of the first limiting portion 1071 is located at the outermost edge of the ink cartridge surface contour; along the direction facing the second sidewall 104, the end of the second limiting portion 1072 is located at the outermost edge of the ink cartridge surface contour. For example... Figure 3The ink cartridge is shown in the following posture, which is the ink cartridge installation posture, i.e., the ink cartridge is installed into the ink cartridge mounting part 2 in this posture. However, once the user becomes accustomed to installing the ink cartridge in this posture, the user is also likely to place the ink cartridge in this posture when the ink cartridge is not in use, such as temporarily placing the ink cartridge on a table. Since the bottom wall 106 of the ink cartridge is relatively narrow, if the ink cartridge is placed in this posture, the ink cartridge is likely to tip over towards the first side wall 103 or the second side wall 104. By providing the end of the first limiting part 1071 along the direction facing the first side wall 103, The outermost part of the ink cartridge surface contour; along the direction facing the second side wall 104, the end of the second limiting part 1072 is located at the outermost part of the ink cartridge surface contour; when the ink cartridge is tilted towards the first side wall 103 or the second side wall 104, the first limiting part 1071 or the second limiting part 1072 will first contact the table or ground where the ink cartridge is placed, thus effectively dispersing the stress caused by the tilt, and preventing the gas exchange part 110 or chip 108 and other components from being damaged due to vibration after the ink cartridge is tilted, which would cause the ink cartridge to be unusable.
[0032] Furthermore, in the embodiments of this application, combined with Figure 4 As shown, the ink cartridge also includes a locking mechanism, which consists of a locking part 111 and an unlocking part 112. The locking mechanism is located on the side of the bottom wall 106 of the ink cartridge near the rear wall 102. When the user applies a pushing force to install the ink cartridge into the ink cartridge mounting part 2, the ink supply needle 25 of the ink cartridge mounting part 2 is connected to the ink supply part 109 of the ink cartridge, and the air guide part 23 is connected to the gas exchange part 110 of the ink cartridge. The ink cartridge is guided and fixed in the mounting cavity 21 of the ink cartridge mounting part 2. When the ink supply needle 25 of the ink cartridge mounting part 2 is inserted into the ink supply part 109, the spring valve 1092 in the ink supply part 109 is compressed. Therefore, the spring valve 1092 exerts a force on the ink cartridge in the opposite direction of the ink cartridge mounting direction. When the user stops applying the pushing force, the ink cartridge will be ejected. By incorporating a locking mechanism consisting of a locking part 111 and an unlocking part 112, the locking part 111 includes a locking surface 1111, and the unlocking part 112 includes an unlocking operating surface 1121. When the ink cartridge is installed in place, the locking surface 1111 engages with the bottom wall of the ink cartridge mounting part 2, allowing the ink cartridge to resist the force of the spring valve 1092 and be stably held in the mounting cavity 21. When it is necessary to remove the ink cartridge, the operator presses the unlocking operating surface 1121 of the unlocking part 112 to separate the locking surface 1111 from the bottom wall of the ink cartridge mounting part 2, allowing the ink cartridge to be removed in the opposite direction of the ink cartridge installation.
[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
