Description

Technical Field

[0001] This utility model relates to the field of printing device technology, and in particular to an ink cartridge with a swingable structure. Background Technology

[0002] In existing technologies, such as the ink cartridge disclosed in Chinese patent CN109715407B, the ink cartridge includes an ink supply port located near the front end and a locking part located at the rear end that cooperates with the printer. The ink cartridge is installed by rotating the rear end of the cartridge upwards around the ink supply port at the front end, causing the locking part at the rear end to contact the cooperating part of the printer, thereby securing the ink cartridge in the ink cartridge mounting part. When the ink cartridge needs to be removed, simply rotating it in the opposite direction will unlock it.

[0003] However, during ink cartridge installation, in order for the ink supply port to accurately align with the ink supply tube in the ink cartridge installation section, the front end of the ink cartridge is usually guided and limited by the installation cavity inside the ink cartridge installation section. When the front end of the ink cartridge is limited, it will affect the overall rotation of the ink cartridge, resulting in the locking part located at the rear end of the ink cartridge not being able to cooperate with the printer. This will cause the ink cartridge to fail to be fixed in the ink cartridge installation section, resulting in ink cartridge installation failure and affecting the user experience.

[0025] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5The illustrated ink cartridge features a swingable structure, comprising a cartridge body 1 and a cover 2. This structure specifically addresses the problem of existing ink cartridges being difficult to engage with the locking mechanism of the mounting portion due to restricted rotation, thus improving assembly convenience and reliability. The cover 2 is fitted onto the side of the cartridge body 1 near the ink cartridge mounting portion (not shown), forming a preliminary assembly relationship between the cartridge body 1 and the cover 2. The top wall of the cover 2 has a first engaging portion 21 integrally formed, and the bottom wall has a second engaging portion 22 integrally formed; correspondingly, the top wall of the cartridge body 1 has a first mating portion 11, and the bottom wall has a second mating portion 12. Through the snap-fit ​​engagement of the first engaging portion 21 with the first mating portion 11, and the snap-fit ​​engagement of the second engaging portion 22 with the second mating portion 12, the separation of the cartridge body 1 from the cover 2 along the ink cartridge mounting direction can be effectively prevented, ensuring the stability of the connection between the two. The height of the inner hole 23 of the cover is greater than the height of the side of the cartridge 1 closest to the ink cartridge mounting part. This dimensional difference provides the cartridge 1 with room to move, allowing the cartridge 1 to swing up and down relative to the cover 2 about the axis along the ink cartridge mounting direction. During installation, the cartridge 1 can swing up and down relative to the cover 2 about the axis along the ink cartridge mounting direction, so that the cartridge 1 can be smoothly installed into the ink cartridge mounting part, avoiding damage to components caused by forced installation.

[0027] In some possible embodiments, refer to Figure 3 and Figure 5 As shown, the bottom wall of the inner hole 23 of the cover is inclined. When the cartridge 1 approaches the cover 2 along the ink cartridge installation direction, the outer wall of the cartridge 1 on the side close to the cover 2 will press against the inclined bottom wall of the inner hole 23 of the cover. The static friction generated by the pressing will fix the cartridge 1 and the cover 2 relatively, which can prevent the cartridge 1 / cover 2 from moving in the installation part after installation, thus preventing the problem of unstable installation caused by the movement of the cartridge 1 / cover 2 in the installation part.

[0028] In some possible embodiments, refer to Figure 2 and Figure 4 As shown, the first mating part 11 is a first protrusion integrally formed on the top wall of the cartridge body 1, and the first joining part 21 is a first through hole opened on the top wall of the cover body 2. The first protrusion can be inserted into the first through hole to achieve a snap-fit. Among them, the first mating part 11 has a first inclined surface 11a on the side near the ink cartridge mounting part. The first inclined surface 11a plays a guiding role when the cartridge body 1 and the cover body 2 are assembled: during assembly, the first protrusion can smoothly slide into the first through hole along the first inclined surface 11a, and the snap-fit ​​can be completed without precise alignment, which significantly reduces the assembly difficulty and improves the assembly efficiency.

[0029] In some possible embodiments, refer to Figure 2 and Figure 5As shown, the second mating part 12 is a second protrusion integrally formed on the bottom wall of the cartridge body 1, and the second joining part 22 is a second through hole opened on the bottom wall of the cover body 2. The second protrusion is embedded in the second through hole, and the mating with the first protrusion and the first through hole forms a "double-point snap-fit" structure, which further strengthens the restriction on the separation of the cartridge body 1 along the installation direction. In addition, a second inclined surface 12a is formed on the side of the second mating part 12 near the ink cartridge mounting part. The second inclined surface 12a has the same function as the first inclined surface 11a, which can guide the second protrusion to slide quickly into the second through hole, optimizing the assembly process of the cartridge body 1 and the cover body 2.

[0030] In some possible embodiments, refer to Figure 4 and Figure 5 As shown, the length of the first protrusion is smaller than the length of the first through hole, and the length of the second protrusion is smaller than the length of the second through hole. This dimension design allows for movement space for the protrusions within the through holes: when the box 1 swings up and down relative to the cover 2 around the installation direction axis, the first protrusion can move slightly along its length within the first through hole, and the second protrusion can move synchronously within the second through hole, preventing the protrusions from being stuck by the inner wall of the through hole and ensuring smooth swinging motion.

[0031] In some possible embodiments, refer to Figure 1 and Figure 2 As shown, a limiting groove 13 is formed on the top wall of the cartridge 1, away from the cover 2. A limiting element (not shown) adapted to the limiting groove 13 is provided inside the ink cartridge mounting section of the printer. When the ink cartridge is pushed into the mounting section to a preset position, the cartridge 1 can move slightly relative to the cover 2 along the installation direction until the limiting groove 13 engages and is fixed with the limiting element, ultimately securing the ink cartridge within the mounting section. This structure prevents the ink cartridge from shifting due to equipment vibration, ink flow, or other factors during use, improving structural stability after installation.

[0032] In some possible embodiments, refer to Figures 1 to 4 As shown, a chip 24 is also fixedly mounted on the top wall of the cover 2. This chip 24 is electrically connected to the detection module of the printing device to realize real-time interaction of ink cartridge information. The first mating part 11 and the first connecting part 21 are positioned lower than the chip 24 to avoid interference from protrusions or through-hole structures during the installation and removal of the chip 24. This ensures that the electrical connection between the chip 24 and the detection module is not affected, and that the chip is not blocked by the snap-fit ​​structure when replacing the chip, thus ensuring the normal functioning of the chip 24.

[0033] In some possible embodiments, refer to Figures 1 to 3As shown, an ink supply section 14 is provided at the lower end of the cartridge body 1. The ink supply section 14 extends along the ink cartridge installation direction and is used to connect with the ink suction assembly of the printing device after the ink cartridge is installed, so as to achieve stable ink delivery. The second mating part 12 and the second connecting part 22 are both positioned higher than the position of the ink supply section 14, which can avoid spatial interference between the snap-fit ​​structure and the ink supply section 14 and the ink suction assembly, ensuring that the ink supply channel is unobstructed and does not affect the normal supply of ink, thereby ensuring print quality.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
