Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a printing device and its ink cartridge that is easy to lock and securely unlock. Background Technology

[0002] In printing equipment, ink cartridges are detachably installed in the recording unit to store and deliver ink. Some existing ink cartridges have complex locking mechanisms that are space-consuming, costly, and have low locking accuracy, making them prone to ink leakage. Other cartridges use a locking channel, unlocking channel, and locking block. When locking, the locking mechanism of the recording unit is pushed in along the locking channel, and then the return of an internal elastic element engages the locking mechanism with the locking block. When unlocking, pressing the cartridge engages the internal structure, causing the locking mechanism to enter the unlocking channel, and then the return of the elastic element ejects the cartridge along the unlocking channel. This type of cartridge facilitates quick locking and unlocking, improves locking accuracy, and prevents ink leakage. However, during unlocking, the elastic element can cause excessive force when ejecting the cartridge, potentially damaging the cartridge or causing injury, posing a safety hazard. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an ink cartridge that is easy to lock and securely unlock, which can realize the quick locking and unlocking of the ink cartridge and avoid damage to the ink cartridge or injury caused by excessive force when the ink cartridge is ejected, thereby improving the security of ink cartridge unlocking.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: an ink cartridge that is easy to lock and securely unlock, comprising an ink cartridge body, the bottom of the ink cartridge body having a locking channel and an unlocking channel, the end of the locking channel having a first guide groove, the beginning of the unlocking channel having a second guide groove, a locking block being provided between the locking channel and the unlocking channel, the side of the locking block near the first guide groove and the second guide groove having a locking recess, the ink cartridge body also having an elastic stop, which can deform under the unlocking force to expand the unlocking channel, allowing the locking structure of the recording device to slide out along the unlocking channel.

[0005] Compared to existing technologies, the advantages of this invention are as follows: When the ink cartridge is locked, the locking structure in the recording device slides into the first guide groove along the locking channel, and then springs back to the locking recess of the locking block for locking, achieving rapid and reliable locking of the ink cartridge and preventing ink leakage. When unlocking, the locking structure first enters the second guide groove, and then pops out along the unlocking channel. The elastic stop within the unlocking channel provides a stop and buffer for the ink cartridge's ejection, preventing damage or injury due to excessive ejection force, thus achieving safe unlocking and improving the security of ink cartridge unlocking. Furthermore, when the ink cartridge ejects, it provides unlocking force to the elastic stop, causing it to deform and expand the unlocking channel, ultimately allowing the locking structure to slide smoothly out along the unlocking channel, achieving rapid unlocking of the ink cartridge.

[0006] The aforementioned ink cartridge, which is easy to lock and securely unlock, has an inlet and outlet at the bottom of the cartridge body that communicates with the locking channel. When the elastic stop is subjected to an unlocking force, the unlocking channel expands, and the unlocking channel communicates with the inlet and outlet.

[0007] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a first guide slope on the sidewall of the inlet and outlet, which slopes away from the locking channel from the beginning to the end of the unlocking channel.

[0008] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a stop at the end of the unlocking channel. The side of the stop away from the second guide groove has a second guide slope. The second guide slope slopes away from the locking channel from the beginning to the end of the unlocking channel, and the second guide slope is connected to the first guide slope.

[0009] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a third guide slope on the side of the stop near the second guide groove, the third guide slope being inclined from the beginning to the end of the unlocking channel toward the locking channel.

[0010] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a fourth guide slope on the side of the elastic stop closer to the unlocking channel and a fifth guide slope on the side of the elastic stop away from the unlocking channel. Both the fourth and fifth guide slopes are inclined away from the locking channel from the beginning to the end of the unlocking channel. When not subjected to unlocking force, the fourth guide slope is in contact with the second guide slope, and the fifth guide slope overlaps the first guide slope.

[0011] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a sixth guide slope on the top wall of the inlet and outlet. The sixth guide slope slopes downward or upward from the beginning to the end of the locking channel toward the end of the inlet and outlet.

[0012] The aforementioned ink cartridge, which facilitates locking and secure unlocking, has a seventh guide slope on the side of the locking block near the locking channel, the seventh guide slope being inclined away from the unlocking channel from the beginning to the end of the locking channel.

[0013] The aforementioned ink cartridge, which is easy to lock and securely unlock, has a welded protrusion at the bottom of the cartridge body. The locking block is fixedly connected to the welded protrusion. The elastic stop includes an elastic extension and a stop. The first end of the elastic extension is integrally formed on the locking block, and the stop is integrally formed on the second end of the elastic extension.

[0014] This utility model also provides a printing device, including the aforementioned ink cartridge that is easy to lock and securely unlock, which has at least all the beneficial effects that the aforementioned ink cartridge that is easy to lock and securely unlock can bring.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below.

[0021] Reference Figures 1 to 3 This utility model provides a printing device and its ink cartridge for easy locking and secure unlocking. The printing device includes a device body and a recording device 100 disposed within the device body. (See reference...) Figure 2 The locking structure 200 of the recording device 100 has a rotating connection portion 210 and a locking portion 220. The locking structure 200 is assembled into the recording device 100 as a separate component via the rotating connection portion 210. (See reference...) Figure 3 When the ink cartridge is assembled with the recording device 100, the locking structure 200 can slide into the corresponding structure at the bottom of the ink cartridge to lock it. When unlocking, the locking structure 200 can slide out from the corresponding structure at the bottom of the ink cartridge.

[0022] Reference Figure 1 This utility model also provides an ink cartridge that is easy to lock and securely unlock, including an ink cartridge body 300. The bottom of the ink cartridge body 300 has a locking channel 310 and an unlocking channel 320, which are located on opposite sides of the bottom of the ink cartridge body 300. The locking channel 310 has a first guide sidewall 311 and a first guide groove 312 at its end. The first guide sidewall 311 slopes towards the first guide groove 312 from the beginning to the end of the locking channel 310. When locking, the locking part 220 of the lock structure 200 first slides into the locking channel 310 and then enters the first guide groove 312 via the first guide sidewall 311. The direction from the beginning to the end of the locking channel 310 is the direction in which the ink cartridge is locked.

[0023] Furthermore, a locking block 330 is provided between the locking channel 310 and the unlocking channel 320. The locking block 330 has a locking recess 331 on the side closest to the first guide groove 312 and the second guide groove 321. The sidewall of the locking recess 331 has a second guide sidewall 332. The first guide groove 312 extends along the Y direction, and the second guide sidewall 332 corresponds to the first guide groove 312 in the Y direction. After the locking part 220 of the locking structure 200 enters the first guide groove 312, it rebounds under the action of the internal elastic member of the recording device 100. Since the second guide sidewall 332 corresponds to the first guide groove 312 in the Y direction, the locking structure 200 will rebound to the second guide sidewall 332 and then enter the locking recess 331 along the second guide sidewall 332. Under the action of the internal elastic member, it is locked in the locking recess 331, thereby achieving cartridge locking.

[0024] Furthermore, the unlocking channel 320 has a second guide groove 321 at its beginning, and a third guide sidewall 340 is located between the first guide groove 312 and the second guide groove 321. The third guide sidewall 340 is inclined from the locking channel 310 to the unlocking channel 320 toward the second guide groove 321, and the third guide sidewall 340 corresponds to the locking recess 331 in the Y direction. The direction from the beginning to the end of the unlocking channel 320 is the same as the direction in which the ink cartridge unlocks; therefore, the direction from the beginning to the end of the unlocking channel 320 is opposite to the direction from the beginning to the end of the locking channel 310. During unlocking, the locking part 220 moves to the third guide sidewall 340 and enters the second guide groove 321 along the third guide sidewall 340. Therefore, the locking part 220 will slide out along the unlocking channel 320 under the action of the elastic element inside the recording device 100. This ink cartridge can achieve fast locking and unlocking, and the trajectory is less likely to deviate during locking and unlocking, resulting in higher locking accuracy and effectively preventing ink leakage.

[0025] Furthermore, the ink cartridge body 300 is also provided with a spring-loaded stop 350, which is closer to the unlocking channel 320. When subjected to unlocking force, the spring-loaded stop 350 can deform to expand the unlocking channel 320, allowing the locking structure 200 of the recording device 100 to slide out along the unlocking channel 320. The spring-loaded stop 350 in the unlocking channel 320 provides a stop and buffer for the ejection of the ink cartridge, preventing damage to the ink cartridge or injury due to excessive ejection force, thus achieving safe unlocking of the ink cartridge and improving the security of ink cartridge unlocking. When the ink cartridge is ejected, it can provide unlocking force to the spring-loaded stop 350, causing the spring-loaded stop 350 to deform and expand the unlocking channel 320, ultimately allowing the locking structure 200 to slide out smoothly along the unlocking channel 320, achieving rapid unlocking of the ink cartridge.

[0026] Specifically, when the elastic stop 350 is subjected to an unlocking force, it can either undergo elastic deformation of the entire structure to make way, or only a portion of the structure can undergo elastic deformation to make way. When not subjected to an unlocking force, the elastic stop 350 can either completely seal the end of the unlocking channel 320, or it can partially block the end of the unlocking channel 320, as long as the stop lock structure 200 can be achieved to prevent the ink cartridge from popping out instantly.

[0027] Furthermore, the bottom of the cartridge body 300 has an inlet / outlet 360 communicating with the locking channel 310. When locked, the locking structure 200 can enter the locking channel 310 through the inlet / outlet 360. When unlocked, the elastic stop 350 is subjected to an unlocking force, causing the unlocking channel 320 to expand and communicate with the inlet / outlet 360, allowing the locking structure 200 to retract from the unlocking channel 320 to the inlet / outlet 360. Of course, when the elastic stop 350 partially blocks the end of the unlocking channel 320, the unlocking channel 320 can also communicate with the inlet / outlet 360 when not subjected to an unlocking force. Preferably, when not subjected to an unlocking force, the unlocking channel 320 does not communicate with the inlet / outlet 360 to avoid affecting the locking part 220's entry into the locking channel 310.

[0028] Furthermore, in some embodiments, the sidewall of the inlet / outlet 360 has a first guide slope 361. The first guide slope 361 slopes away from the locking channel 310 from the beginning to the end of the unlocking channel 320. When locking, the locking structure 200 does not enter along the straight Y direction, but is guided by the first guide slope 361, making it less prone to deviation and allowing for more accurate entry into the locking channel 310, which is more conducive to the rapid locking of the ink cartridge. Of course, in other embodiments, the locking structure 200 may also enter the locking channel 310 without passing through the first guide slope 361.

[0029] Furthermore, the bottom of the ink cartridge body 300 is provided with a welding protrusion 370, and the locking block 330 is fixedly connected to the welding protrusion 370. The elastic stop 350 includes an elastic extension 351 and a stop 352. The first end of the elastic extension 351 is integrally formed with the locking block 330, and the stop 352 is integrally formed with the second end of the elastic extension 351. The elastic extension 351 is a slender structure, which is more prone to deformation when subjected to unlocking force, deviating towards the unlocking channel 320, thereby expanding the unlocking channel 320.

[0030] Furthermore, a stop 322 is provided at the end of the unlocking channel 320. The side of the stop 322 away from the second guide groove 321 has a second guide slope 3221. The second guide slope 3221 slopes away from the locking channel 310 from the beginning to the end of the unlocking channel 320, and is connected to the first guide slope 361. A third guide slope 3222 is provided on the side of the stop 322 closer to the second guide groove 321. The third guide slope 3222 slopes towards the locking channel 310 from the beginning to the end of the unlocking channel 320. During unlocking, the locking part 220 slides outward along the unlocking channel 320. Through the action of the third guide slope 3222, the elastic stop 350 can be better pushed open, thus smoothly expanding the unlocking channel 320. After the expansion unlocking channel 320 is expanded, the locking part 220 continues to slide outward. It can smoothly slide out of the unlocking channel 320 via the second guide slope 3221, and slide out of the ink cartridge from the inlet / outlet 360 via the first guide slope 361.

[0031] Furthermore, the elastic stop 350 has a fourth guide slope 3521 on the side near the unlocking channel 320 and a fifth guide slope 3522 on the side away from the unlocking channel 320. Both the fourth guide slope 3521 and the fifth guide slope 3522 slope away from the locking channel 310 from the beginning to the end of the unlocking channel 320. When not subjected to unlocking force, the fourth guide slope 3521 fits against the second guide slope 3221 to ensure the stopping effect of the elastic stop 350. In addition, the elastic stop 350 can also separate the locking channel 310 and the unlocking channel 320, so that the locking part 220 can accurately enter the locking channel 310 when locking. Furthermore, when not subjected to unlocking force, the fifth guide slope 3522 overlaps with the first guide slope 361. When the ink cartridge is locked, the locking part 220 can smoothly slide along the first guide slope 361 to the fifth guide slope 3522, and then smoothly enter the locking channel 310 without being affected by the elastic stop 350.

[0032] Furthermore, the top wall of the inlet / outlet 360 has a sixth guide slope 362, which slopes upward or downward from the beginning to the end of the locking channel 310 toward the end of the inlet / outlet 360. Through the guiding cooperation of the first guide slope 361 and the sixth guide slope 362, the locking part 220 can be better prevented from sliding in the Y direction, is less likely to deviate from the track, and slides into the locking channel 310 more smoothly.

[0033] Furthermore, the locking block 330 has a seventh guide slope 333 on the side near the locking channel 310. The seventh guide slope 333 is inclined away from the unlocking channel 320 from the beginning to the end of the locking channel 310, so as to further guide the locking part 220 to slide to the first guide sidewall 311 and smoothly enter the first guide groove 312.
