[0043] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0044] See also Figure 1-Figure 5 , shows an ink cartridge protection device according to a preferred embodiment of the present invention, comprising:

[0045] The main housing 1 has a housing chamber 11, a mounting opening 12, and a sealing portion 31. The housing chamber 11 is used to accommodate the ink cartridge. The mounting opening 12 communicates with the housing chamber 11 and is used for allowing the ink cartridge to enter and exit the housing chamber 11. The sealing portion 31 is located in the housing chamber 11 and is used to abut against the inkjet head and surround the inkjet head's nozzle to seal the inkjet head's nozzle.

[0046] The cover 2 is openably and closably mounted on the main housing 1 . The cover 2 covers the mounting opening 12 , and is used to abut against the ink cartridge to maintain contact between the inkjet head and the sealing portion 31 .

[0047] When the printer is turned off, shut down, or not used for an extended period at low temperatures, the ink cartridge is removed and placed in the accommodating chamber 11, ensuring that the inkjet head abuts the sealing portion 31. The cover 2 is then closed, and the cover 2 abuts against the ink cartridge, preventing the cartridge from leaving the accommodating chamber 11. At the same time, the inkjet head maintains contact with the sealing portion 31, reliably sealing the inkjet head's nozzle and isolating it from the outside air. This prevents the ink at the nozzle from evaporating and hardening, thus protecting the inkjet head. The protective device also incorporates a built-in heating system, preventing the ink in the cartridge from solidifying or freezing during transportation or storage in low-temperature environments. The device features a simple, practical structure, low cost, and convenient operation.

[0048] See also Figure 4In one embodiment, a protective box 3 is provided in the accommodating chamber 11. The protective box 3 has a protective groove 32 and a sealing portion 31 located in the protective groove 32. The protective groove 32 is configured to be arranged around the inkjet head, and the sealing portion 31 is configured to be arranged around the nozzle of the inkjet head. In this way, the accommodating chamber 11 can be used to accommodate the main box body of the ink cartridge, and the protective groove 32 can be used to accommodate the inkjet head of the ink cartridge, which can provide better protection for the main box body and the inkjet head of the ink cartridge. At the same time, an avoidance space can be enclosed between the inkjet head and the protective groove 32 to facilitate the installation of the humidification structure 4 described below.

[0049] In one embodiment, the protection box 3 is a structure made of rubber material, and the protection box 3 and the sealing part 31 are arranged in one piece, that is, the protection box 3 and the sealing part 31 are an integrally formed structure made of rubber material, so that the sealing part 31 can reliably seal the spray hole, and the protection box 3 and the sealing part 31 can be connected without a connection structure, which can simplify the structure and be more convenient to install.

[0050] Of course, in other embodiments, the protection box 3 and the sealing part 31 are separately provided, that is, the protection box 3 and the sealing part 31 are independent structures, and the sealing part 31 is made of rubber material. In this way, the nozzle hole can also be well sealed.

[0051] See also Figure 5 In one embodiment, the ink cartridge protection device further comprises:

[0052] The humidifying structure 4 is provided in the main shell 1 and is located on a side close to the protective groove 32. The humidifying structure 4 is used to humidify the ambient air of the protective groove 32 so that the ambient air at the sealing part maintains an appropriate humidity, thereby maintaining an appropriate humidity at the nozzle hole and preventing the ink at the nozzle hole from hardening due to excessive drying.

[0053] In one embodiment, the humidifying structure 4 includes:

[0054] A water tank 41 is provided in the main housing 1;

[0055] a water pump (not shown), the water inlet of the water pump being connected to the water outlet of the water tank 41;

[0056] The nozzle 42 is provided on the main housing 1 and extends to the protection tank 32. The nozzle 42 is connected to the water outlet of the water pump and is used to spray water into the space within the protection tank 32.

[0057] A humidity sensor 43 is provided in the main housing 1 and is used to detect the ambient humidity in the protective groove 32; and

[0058] The controller 5 is disposed within the main housing 1 and is electrically connected to the water pump and the humidity sensor 43. The controller 5 is configured to control the water pump on and off based on feedback from the humidity sensor 43. Thus, the humidity sensor 43 monitors the ambient air humidity within the protective tank 32 in real time. When the ambient air humidity within the protective tank 32 falls below a set value, the controller 5 receives feedback from the humidity sensor 43 and, based on this feedback, controls the water pump to turn on. The water pump then pumps water from the water tank 41 to the nozzle 42, causing the nozzle 42 to spray water toward the protective tank 32. This maintains an appropriate humidity within the protective tank 32, preventing the ink from hardening at the nozzle orifice. After the spraying is complete, the controller 5 controls the water pump to turn off.

[0059] Of course, in other embodiments, the humidifying structure 4 may further include:

[0060] The sponge is arranged in the protective groove 32. Before placing the ink cartridge in the accommodating cavity 11, the sponge is first soaked, and then the ink cartridge is placed in the accommodating cavity 11. The soaked sponge contains water, which can keep the ambient air in the protective groove 32 at an appropriate humidity. It can also prevent the ink at the nozzle from hardening due to excessive drying. The structure is simple, practical and low-cost.

[0061] In one embodiment, the ink cartridge protection device further comprises:

[0062] The heater 6 is provided in the main housing 1 and is used to heat the ambient air in the main housing 1;

[0063] The temperature sensor 7 is provided in the main housing 1 and is used to detect the ambient temperature in the main housing 1;

[0064] The controller 5 is disposed in the main housing 1 and is electrically connected to the heater 6 and the temperature sensor 7. The controller 5 is also used to control the heater 6 to turn on and off according to the feedback information from the temperature sensor 7. In this way, the ambient temperature inside the main housing 1 is monitored in real time by the temperature sensor 7. When the ambient temperature inside the main housing 1 is lower than a set value, the controller 5 receives the feedback information from the temperature sensor 7 and controls the heater 6 to turn on according to the feedback information, so that the heater 6 heats the ambient air inside the main housing 1. After the ambient air inside the main housing 1 reaches the set temperature, the controller 5 turns off the heater 6 according to the feedback information from the temperature sensor 7. This can effectively prevent the ink from solidifying or freezing due to the low temperature environment, and can provide good protection for the inkjet head.

[0065] The heater 6 may include a heating plate or a heating tube, as long as it can heat the ambient air in the main shell 1 .

[0066] In one embodiment, the ink cartridge protection device further comprises:

[0067] an ejector rod 8 movably disposed on the main housing 1 and located in the accommodating chamber 11 , the ejector rod 8 having a retracted state for being abutted by the ink cartridge and an extended state for ejecting at least a portion of the ink cartridge out of the accommodating chamber 11 ; and

[0068] The first elastic member 9 is disposed between the main housing 1 and the ejection rod 8. The first elastic member 9 is used to provide a driving force for the ejection rod 8 to maintain its extended state. Thus, when the ink cartridge is placed in the accommodating chamber 11, the ink cartridge abuts against the ejection rod 8, causing the ejection rod 8 to switch to a retracted state. When the cover 2 is opened, the first elastic member 9 returns to its original position, pushing the ejection rod 8 upward, causing the ejection rod 8 to switch to an extended state, thereby pushing at least a portion of the ink cartridge out of the accommodating chamber 11, making it easier for the user to remove the ink cartridge and significantly reducing the difficulty of removing the ink cartridge.

[0069] In one embodiment, the main shell 1 has a guide hole, which extends along the moving direction of the ejector rod 8. The guide hole is connected to the accommodating cavity 11. The ejector rod 8 is movably inserted into the guide hole. The first elastic member 9 is located in the guide hole. In this way, the ejector rod 8 and the first elastic member 9 can be moved in the direction of movement, so that the ejector rod 8 and the first elastic member 9 can move more smoothly and stably.

[0070] In one embodiment, the first elastic member 9 may be a spring, which is sleeved on the ejection rod 8 , with the lower end of the spring abutting against the bottom wall of the guide hole, and the upper end of the spring abutting against the ejection rod 8 .

[0071] Of course, in other embodiments, the first elastic member 9 may also be a spring, as long as it can provide driving force for the ejection rod 8 .

[0072] In one embodiment, a shock-absorbing pad 10 is provided in the accommodating chamber 11. The shock-absorbing pad 10 is used to abut against the ink cartridge to limit the ink cartridge from shaking in the accommodating chamber 11, ensuring that the inkjet head and the sealing portion 31 are reliably abutted. At the same time, it can also prevent the ink cartridge from shaking randomly and being damaged.

[0073] In one embodiment, one of the two opposite sides of the cover body 2 is rotatably connected to the main housing 1 and the other side has a latch hole 21;

[0074] The cartridge protector also includes:

[0075] The buckle body 20 is movably mounted on the main housing 1 and has a buckle portion 201. The buckle portion 201 has a locked state connected to the latch hole 21 and an unlocked state disconnected from the latch hole 21. The buckle portion 201 switches between the locked state and the unlocked state as the buckle body 20 moves.

[0076] The second elastic member 30 is disposed between the main housing 1 and the buckle body 20. The second elastic member 30 is used to provide a driving force to the buckle body 20, which keeps the latch portion 201 in a locked state. Thus, when the cover 2 is closed, the latch portion 201 engages with the latch hole 21, allowing the cover 2 to reliably seal the mounting opening 12. When the cover 2 is opened, the buckle body 20 is manipulated to move, thereby driving the latch portion 201 from the locked state to the unlocked state. This provides a highly reliable structure and convenient operation.

[0077] In one embodiment, the outer wall of the main shell 1 has an avoidance hole, and the buckle body 20 is provided with a pressing portion 202, and the pressing portion 202 is movably provided with the avoidance hole. In this way, the buckle body 20 can be pushed to move by applying pressure to the pressing portion 202, thereby switching the buckle portion 201 from a locked state to an unlocked state, and the unlocking operation is convenient.

[0078] In one embodiment, the lower end of the buckle body 20 is hinged to the main shell 1, so that the buckle body 20 can swing back and forth relative to the main shell 1, so that the buckle portion 201 can switch between a locked state and an unlocked state. The second elastic member 30 is a torsion spring, which is sleeved on the hinge axis of the buckle body 20, and the first connecting arm of the torsion spring is against the main shell 1, and the second connecting arm of the torsion spring is against the buckle body 20.

[0079] In one embodiment, the ink cartridge protection device further comprises:

[0080] The third elastic member 40 is provided between the main shell 1 and the cover body 2. The third elastic member 40 is used to provide a driving force to the cover body 2 to maintain it in an open state, thereby providing an opening force to the cover body 2 when opening the cover body 2, making the opening of the cover body 2 more convenient. At the same time, the cover body 2 can be maintained in an open state, making it easier to place and remove the ink cartridge.

[0081] In one embodiment, the third elastic member 40 is a torsion spring, which is sleeved on the hinge axis of the cover body 2 , with the first connecting arm of the torsion spring abutting against the main shell 1 , and the second connecting arm of the torsion spring abutting against the cover body 2 .

[0082] In one embodiment, the main housing 1 comprises:

[0083] a housing 13 having a mounting cavity; and

[0084] The bracket 14 is disposed in the installation cavity and forms a receiving cavity 11 with the housing 13 . The bracket 14 supports the ink cartridge so that the ink cartridge is securely placed in the receiving cavity 11 .
