Description

Technical Field

[0001] This invention relates to the field of ink cartridge technology, and more particularly to an anti-overflow safety ink cartridge. Background Technology

[0002] Ink cartridges primarily refer to the components in inkjet printers used to store printing ink and ultimately complete the printing process. A patent document with authorization announcement number CN2767168Y discloses a novel printer ink cartridge, including a cartridge body, a cover, a reflective device, and a photosensitive device. The reflective device is a mirror surface. It is located at the bottom of the cartridge body, with an ink passage between it and the bottom plate. The bottom plate of the cartridge body is inclined, with the ink outlet located at the lowest point of the bottom plate, and the reflective device higher than the ink outlet. Compared to existing printer ink cartridges, it has the advantages of simple structure, low cost, and ease of manufacturing. It can also reduce the amount of residual ink in the cartridge after use. It is widely applicable to various printer models and is an ideal replacement for existing printer ink cartridges.

[0003] However, printer ink cartridges serve to store ink. When refilling them, the cartridge cover needs to be opened, and ink needs to be injected into the cartridge using a syringe. Since the cartridge is made of black plastic, the ink level is not clearly visible during refilling, which can easily lead to ink overflow. In addition, the rubber stopper is relatively loose and can easily slip off. When the cartridge is shaken, ink can also easily overflow. Therefore, we have proposed an anti-overflow safety ink cartridge to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-overflow safety ink cartridge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An overflow-proof safety ink cartridge includes a cartridge body, a cover, and a fixing frame. The cover is mounted on top of the cartridge body. A sealing gasket is fixedly installed at the bottom of the cover, and the sealing gasket is in contact with the cartridge body. A fixing frame is fixedly installed on the outer side of the cover, and a fixing mechanism is provided between the fixing frame and the cartridge body. An ink filling hole is provided at the top of the cover. A stopper plate is provided above the cover. A sealing plug adapted to the ink filling hole is fixedly installed at the bottom of the stopper plate. A second sealing gasket is fixedly installed at the bottom of the stopper plate, and the second sealing gasket is in contact with the cover. The top of the box cover has a rotating hole, in which a rotating rod is rotatably installed. A guide groove is provided on one side of the rotating rod, and a pressing seat is slidably installed in the guide groove. The pressing seat is adapted to the stopper plate. A threaded hole two is provided on the top inner wall of the guide groove, and a pressing screw is installed in the threaded hole two. The bottom end of the pressing screw is rotatably installed on the pressing seat. A rotating plate is fixedly installed on the top end of the pressing screw. A horizontal plate is fixedly installed on the bottom of the rotating rod. An air bladder is fixedly installed on the top of the horizontal plate, and the air bladder is adapted to the ink filling hole.

[0007] Preferably, the top of the extrusion seat is provided with a rotating groove, the inner wall of the rotating groove is provided with an annular groove, and an annular seat is fixedly installed on the extrusion screw, and the annular seat is rotatably connected to the annular groove.

[0008] Preferably, a piston groove is provided on the bottom inner wall of the guide groove, and a connecting pipe connected to the piston groove is installed on the air injection port of the airbag.

[0009] Preferably, a vertical rod is fixedly installed at the bottom of the extrusion seat, the bottom end of the vertical rod extends into the piston groove and a piston is fixedly installed thereon, and the piston and the piston groove are slidably sealed together.

[0010] Preferably, the fixing mechanism includes a trapezoidal groove, a movable groove, and a fixing pin. Multiple trapezoidal grooves are provided on the outer side of the ink cartridge body, and multiple movable grooves are provided on the inner wall of the fixing frame. A fixing pin is slidably installed in the movable groove, and the fixing pin is adapted to the corresponding trapezoidal groove.

[0011] Preferably, a threaded hole is provided on one inner wall of the movable groove, and a fixing screw is installed in the threaded hole. One end of the fixing screw is rotatably connected to a fixing pin, and a knob is fixedly installed on the other end of the fixing screw.

[0012] Preferably, the top of the box cover is provided with a sliding groove, a sliding seat is slidably installed in the sliding groove, and an engagement mechanism is provided between the sliding seat and the rotating rod.

[0013] Preferably, the mating mechanism includes a slot and a socket, with slots provided on both sides of the rotating rod, and the socket is fixedly installed on one side of the sliding seat, and the socket is adapted to the corresponding slot.

[0014] Preferably, the same guide rod is fixedly installed on the inner walls of both sides of the sliding groove, and the sliding seat is slidably sleeved on the corresponding guide rod.

[0015] Preferably, a fixing spring is fixedly installed on one side of the inner wall of the sliding groove, and one end of the fixing spring is fixedly installed on the sliding seat.

[0016] The beneficial effects of this invention are:

[0017] 1. After maintaining the ink cartridge body, install the cartridge cover and fixing frame onto the top of the ink cartridge body. At this time, the sealing gasket at the bottom of the cartridge cover is in contact with the ink cartridge body. With the cooperation of the knob, fixing screw, threaded hole, and fixing pin, the fixing pin can be inserted into the trapezoidal groove. The fixing pin can press the inclined side of the trapezoidal groove. At this time, the fixing pin can move downward along the inclined side. The fixing pin can drive the fixing frame and cartridge cover to move downward and press the sealing gasket, thereby increasing the sealing between the cartridge cover and the ink cartridge body and preventing ink from overflowing from the cartridge cover and ink cartridge body.

[0018] 2. Ink can be added to the ink cartridge body through the ink filling hole. When the ink level rises, the ink enters the observation window and is displayed through the transparent glass, thus reminding the staff to fill it. Inserting the sealing plug on the stopper plate into the filling hole can initially seal the filling hole.

[0019] 3. By moving the sliding seat and socket, the rotating rod can be fixed and unfixed. By rotating the rotating rod, the rotating rod can drive the squeezing rod to rotate directly above the stopper plate, and the rotating rod can drive the horizontal plate and airbag to rotate directly below the ink filling hole.

[0020] 4. Through the rotating plate, the extrusion screw and the second threaded hole, the extrusion screw can drive the extrusion seat to move downwards. The extrusion seat can extrude the stopper plate, and the stopper plate can extrude the second sealing gasket, which can increase the sealing performance of the filling hole. The extrusion seat can drive the piston downwards through the vertical rod. The piston can inject the gas in the piston groove into the air bladder through the connecting pipe, so that the air bladder can expand and seal the ink filling hole, thereby preventing ink from overflowing from the ink filling hole.
