Fig. 5 is a schematic view of an ink supply device 200 according to an embodiment of the present invention, fig. 6 is a perspective view of a guide base 21 according to an embodiment of the present invention, and fig. 7 is a sectional view of the guide base of fig. 6; fig. 9 is a schematic diagram of the ink adding device 200 of the present invention for adding ink to the pen 100, and fig. 10 is a partially enlarged schematic diagram of the area B in fig. 9.

As shown in fig. 5-7 and fig. 9 and 10, the ink adding device 200 of the present invention is used for adding ink to the pen 100 capable of adding ink, and the ink adding device 200 includes an elastic ink bottle 20 and a guide seat 21 connected to a bottle mouth 201 of the elastic ink bottle 20.

The diversion seat 21 is provided with a convex part 212 matched with the concave part 134 of the pen 100 capable of adding ink, the convex part 212 is provided with at least one top plate 213, the diversion seat 21 is provided with an ink outlet 211, the ink outlet 211 is connected with a diversion tube 22, and the diversion tube 22 extends into the elastic ink bottle 20.

When the convex portion 212 is inserted into the concave portion 134, the top plate 213 passes through the liquid passing window 133 to push the piston 122 to move in a direction away from the limiting portion 132, so that the sealing plug 131 is separated from the ink feeding hole 124. By squeezing the elastic ink bottle 20, the ink in the elastic ink bottle 20 flows out from the ink outlet 211 through the fluid guiding tube 22, passes through the liquid passing window 133, passes through the ink adding hole 124 of the pen 100 capable of adding ink, passes through the ink adding tube 14, and enters the ink storing cavity 101.

When the fluid guide tube 21 extends into the elastic ink bottle 20, the free end of the fluid guide tube 21 extends to the lowest circumferential position of the bottom of the elastic ink bottle 20, so that the ink in the elastic ink bottle 20 can be filled to the maximum extent.

The free end of the draft tube 21 is provided with a V-shaped notch, so that the free end of the draft tube 21 is prevented from being blocked when contacting other peripheral planes to influence liquid suction.

When the convex portion 212 is inserted into the concave portion 134, a sealing ring 214 is disposed between the convex portion 212 and the concave portion 134, and the sealing ring 214 can be sleeved on the convex portion 212, as shown in fig. 6 and 7.

As shown in fig. 5, the ink filling device 200 of the present invention further includes a cap 23, a sealing rod 231 capable of sealing the ink outlet 211 is disposed in the middle of the cap 23, and the cap 23 covers the protrusion 212 of the diversion seat 21 when ink filling is not required. The sealing ring 214 may function to seal the cap 23 and the deflector seat 21.

The center of the bottom of the elastic ink bottle 20 protrudes upward, so that the bottom of the elastic ink bottle 20 is conical. The conical bottom portion guides the free end of the tube 22 extending into the bottle to naturally extend to a line of the circumference of the bottom of the flexible ink bottle 20 at the lowest position, thereby ensuring maximum drawing of residual ink.

In the embodiment shown in fig. 6, the number of the top sheets 213 is 3, and the number of the top sheets can be set as desired.

Fig. 8 is a schematic view of a diversion seat 21 according to another embodiment of the present invention, as shown in fig. 8 and 10, a conical groove 2121 is formed at the top of the convex portion 212, and the bottom of the groove 2121 is connected to the ink outlet 211. This makes the top of the protrusion 212 funnel-shaped to facilitate the ink backflow and avoid ink residue.

With continued reference to fig. 9 and 10, when the ink pen 100 capable of adding ink needs to add ink, the bottle cap 23 of the ink adding device 200 is removed, the pen 100 capable of adding ink is erected, the pen tail plug 13 of the pen 100 capable of adding ink is aligned with the diversion seat 21 of the ink adding device 200, then the convex part 212 of the diversion seat 21 is inserted into the concave part 134 of the pen tail plug 13 of the pen 100 capable of adding ink, at this time, the top plate 213 passes through the liquid passing window 133 to push the piston 122 to move in the direction away from the limiting part 132, so that the sealing plug 131 is separated from the ink adding hole 124, and at this time, the ink adding operation can be performed.

When the bottle body of the elastic ink bottle 20 is pressed in the directions indicated by the arrows on both sides of the elastic ink bottle 20 in fig. 9, the air pressure in the bottle rises, and the ink flows in the directions indicated by the arrows in fig. 9 and 10, and the ink in the elastic ink bottle 20 flows out from the ink outlet 211 through the flow guide tube 22, passes through the liquid passing window 133, passes through the ink filling hole 124 of the pen 100 capable of filling ink, passes through the ink filling tube 14, and enters the internal ink storage chamber 101. When the elastic ink bottle 20 is released, the air pressure in the bottle drops suddenly, and all the ink in the passage through which the ink flows and the air in the ink storage cavity 101 are drawn back to the elastic ink bottle 20, thereby completing the ink adding process. The body of the flexible ink bottle 20 is repeatedly squeezed and released to complete the ink filling process for a plurality of times until the ink level in the ink storage chamber 101 is flush with the free end of the ink filling tube 14, and the ink filling is declared to be completed.

The pen 100 capable of adding ink of the invention, the pen tail plug 13 and the piston valve 12 are matched to be made into a conductive structure with a normally closed valve, the pen tail plug 13 is inserted on the ink adding device 200 of the invention, and the ink can ascend by extruding the bottle body of the elastic ink bottle 20, thereby replenishing the ink storage cavity 101 of the pen 100 capable of adding ink. The invention can obviously improve the ink adding efficiency and eliminate the dirt risk when the user operates, greatly prolongs the service life of the pen, improves the utilization efficiency of non-renewable resources such as plastics and the like, and greatly reduces the environmental pollution of plastics and ink residues caused by discarding writing tools or ink bags.
