Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the following describes the ink bag replaceable type direct liquid ball pen in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-6, a replaceable ink bag type direct liquid ball pen comprises a pen holder 100, a pen nozzle 200, an ink bag 300 and a pen point 400, wherein the pen holder 100 is connected with the pen nozzle 200 to form a pen cavity, and an air pressure balance plug 500, an ink guiding core 600 and a leakage-proof cotton 700 are arranged in the pen nozzle 200; one side of the air pressure balance plug 500 is provided with a boss 510, the other side is provided with a clamping groove 520, the ink bag 300 is detachably clamped on the boss 510, and the anti-leakage cotton 700 is arranged in the clamping groove 520; the air pressure balance plug 500 is provided with a first through hole 530, the anti-leakage cotton 700 is provided with a second through hole, the ink guiding core 600 penetrates through the first through hole 530, one end of the ink guiding core 600 is positioned in the boss 510, the other end of the ink guiding core 600 is positioned in the second through hole, one end of the pen point 400 is fixed in the second through hole 530, and the other end of the pen point penetrates out of the pen nozzle 200 for writing. Specifically, the air pressure balance plug 500 may play a role in balancing air exchange, and when writing, since the ink in the ink bag 300 is drained downwards, the air pressure of the air pressure balance plug 500 near the ink bag 300 is reduced, the air pressure of the air pressure balance plug 500 near the anti-leakage cotton 700 is increased, so that air flows from the anti-leakage cotton 700 side of the air pressure balance plug 500 to the ink bag 300 side through the first through hole 530, and the pen point can normally and continuously discharge ink for writing.

According to the technical scheme, the boss 510 is arranged on the air pressure balance plug 500, when the ink bag 300 needs to be replaced, the ink bag 300 is pulled out of the boss 510 only by a little force, and then a new ink bag 300 is clamped on the boss 510. Specifically, the new ink bag has a thin film layer at the end near the junction, and the film end is clamped into the boss 510. Because the clamping groove 520 is arranged on the other side of the air pressure balance plug 500, the anti-leakage cotton 700 is arranged in the clamping groove 520, and the anti-leakage cotton 700 is filled with ink through the ink guiding core 600 and then is conveyed to the pen point 400, when the ink bag 300 is replaced, the anti-leakage cotton 700 is filled with ink, so that writing can be continued, the time of waiting for drainage of a new ink bag 300 is avoided, and great convenience is brought to people. When the ink on the anti-leakage cotton 700 is used up, the new ink bag 300 is also drained to the anti-leakage cotton 700 after a certain time, so that the pen can continuously write normally.

As shown in fig. 6, in the present embodiment, a vertical protrusion 531 that mates with the ink guiding core 600 is provided in the first through hole 530, and the vertical protrusion 531 mates with the ink guiding core 600, so that the ink can be smoothly guided.

As shown in fig. 1, in the present embodiment, an internal thread 110 is disposed at one end of the pen holder 100 near the pen nozzle 200, an external thread 221 matching with the internal thread 110 is disposed on the pen nozzle 200, and the pen holder 100 and the pen nozzle 200 are connected by screwing, so that the assembly and disassembly are convenient and stable.

As shown in fig. 5, in this embodiment, the pen tip 200 is detachably connected to a pen cap 800, specifically, the pen tip may be connected by a snap fit or the like.

As shown in fig. 1, in the present embodiment, the pen nozzle 200 includes a holding portion 210, a first connecting portion 220 and a second connecting portion 230, the first connecting portion 220 and the second connecting portion 230 are located at two ends of the holding portion 210, the first connecting portion 220 is used for connecting with the pen holder 100, and the second connecting portion 230 is used for connecting with the pen cap 800.

Further, the grip portion 210 is provided with an anti-slip portion 211, and the anti-slip portion 211 may be a tooth pattern, a gum cover, or the like, and the specific form of the anti-slip portion 211 is not limited herein. The anti-slip part 211 is arranged to prevent slipping caused by sweat on the hand when the pen is held by the hand.

Further, the outer diameters of the first connecting portion 220 and the second connecting portion 230 are smaller than the outer diameter of the hand-held portion 210, when the first connecting portion 220 is connected to the pen holder 100, the outer diameter is just equal to the outer diameter of the hand-held portion 210, and when the second connecting portion 230 is connected to the pen cap 800, the outer diameter is just equal to the outer diameter of the hand-held portion 210, so that the whole pen is easier to hold and more attractive.

As shown in fig. 6, a plurality of clamping members 521 for fixing the anti-leakage cotton 700 are disposed in the clamping groove 520, and the clamping members 521 can fix the anti-leakage cotton 700 in the clamping groove 520, and in this embodiment, the clamping members 521 include a plurality of clamping bars equidistantly disposed around an inner wall of the clamping groove 520.

In this embodiment, the air pressure balance plug 500 is made of plastic, has low cost and easy processing, and has a shape-changing force, so that the ink bag 300 and the leak-proof cotton 700 can be conveniently assembled and disassembled.

In this embodiment, a visible window (not shown) is provided on the pen holder 100, so that the remaining amount of ink in the ink cartridge 300 can be checked at any time, and a new ink cartridge 300 can be replaced in time.
