In addition, when the ink in the ink bottle is full, sucking It is also easy to stain the pen. In addition, the previous generation of ink-filled bottles designed by the inventors (patent name: anti-overfill liquid bottle, patent number: 201310113631.X) solved the above problems, but the following problems occurred in the market sales:

(1) When the bottle cap is removed when the outside temperature is high, there is a case where the ink overflows from the needle tube, which is easy to cause waste and pollution;

(2) During the transportation process, when the ink bottle is inverted or when the ink bottle is subjected to strong vibration, the ink inside the bottle may overflow;

(3) If the ink pen is not used for a long time, the ink in the pen end will evaporate, which will cause the ink concentration in the pen to be too large, which may cause the ink path to be blocked and the writing to be poor. At this time, in order to make the ink path of the ink pen clear, the ink in the pen should be removed to inject new ink. However, the existing ink refilling bottle cannot realize the above-mentioned ink refilling function;

The working principle of the present invention is described below. The present invention mainly utilizes the compressible buckling structure of the bottle 3, and when the ink pen body or the upper bottle body 1 placed on the support base 41 is pressed by an external force, the upper bottle body is used. 1 descending with the ink pen body, the middle portion of the bottle liner 3 is under the action of the limiting portion 21 of the lower bottle body 2, and the small diameter portion 32 of the bottle liner 3 is compressed, and under the action of the pushing of the syringe 4, the bottle liner 3 is large. The diameter portion 31 is stretched, and the compressed length of the small diameter portion 32 and the stretched length of the large diameter portion 31 are the same, the volume of the bottle 3 is increased, and the internal pressure is reduced, so that the internal pressure of the inside of the bottle 3 is smaller than that of the ink. The internal pressure in the pen and the bladder, so that the air in the pen and the remaining ink are sucked into the bottle liner 3 along the needle tube 44 and the hose 45, thereby realizing the ink returning action; when the above-mentioned ink returning action is completed, the pressure outside the bottle is released, In the action of the spring 6, the upper bottle body 1 and the bottle liner 3 are reset, and the middle portion of the bottle liner 3 is acted upon by the stopper portion 21 of the lower bottle body 2, and the large diameter portion 31 of the bottle liner 3 is compressed, and the cylinder 4 is pushed up. Under the action, the small diameter portion 32 of the bottle 3 is stretched, and the compressed length and the large diameter portion of the large diameter portion 31 at this time 31 has the same stretching length, the volume of the bottle 3 becomes smaller, and the internal pressure becomes larger, so that the internal pressure inside the bottle 3 is larger than the internal pressure in the ink pen, so that the ink in the bottle 3 passes through the hose 45. The needle tube 44 is rushed toward the pen to realize the ink filling operation. When the internal pressure inside the bottle 3 is equal to the external air pressure (that is, the internal pressure in the ink pen pencil), the pen tail is pulled out to complete the ink filling. It can be seen that the ink bottle of the present invention achieves the effects of prior ink return and post ink injection.

It should be noted that the present invention designs the air hole 47 on the support base 41 so that the ink in the bottle does not overflow from the needle tube 44 when the bottle cap is removed due to the high external temperature; the volume change of the bottle liner 3 should be slightly It is greater than or equal to the volume change of the ink pen pencil to ensure an equal volume of ink filling; since the upper end of the needle tube 44 is used for connecting the ink pen pencil, the diameter of the ink pen should not be too large, so as to ensure that the ink in the bottle is slow. The flow rate enters the pen biliary; and since the lower end of the pedestal seat 42 is used for pressing the bottom surface of the bottle biliary 3, the pipe diameter should not be too small, and the stress concentration is prevented from causing fatigue wear on the bottom surface of the bottle urethane 3 .

It can be seen from the above analysis that the ink refilling bottle provided by the invention has two functions of ink returning and ink refilling, and is convenient to use and simple in operation. Moreover, the ink returning operation is completed before the ink filling operation, and there is no problem of ink overflow during the ink filling process. In addition, the present invention has a simpler core structure, a lower manufacturing cost, and a more beautiful appearance than similar products.

The ink bottle provided by the present invention further includes a bottle cover 7, which is covered on the mouth of the upper bottle body 1. The cap 7 is provided with a second seal 71 that is sealingly coupled to the upper end of the needle tube 44. The second sealing member 71 is preferably made of flexible rubber or silica gel, and has a blind hole in the center thereof. When the ink bottle is idle, the upper end of the needle tube 44 is inserted into the blind hole, and the blind hole and the needle tube are inserted into the blind hole. An interference fit between the upper ends of the 44 ensures that the ink in the bottle does not overflow along the needle tube 44 even when the ink bottle is idle. Further, the cap 7 is provided with a third seal 72 that seals the air hole 47. The third sealing member 72 is preferably made of flexible rubber or silica gel. When the cap 7 covers the mouth of the upper bottle body 1, the air hole 47 is just tightly sealed by the third sealing member 72, so that the inside of the bottle liner 3 forms a sealed independent space. Preventing the ink bottle from being placed in an incorrect position during transportation. For example, when the ink is inverted, the ink in the bottle will flow into the connection gap between the bottle cap 7 and the mouth of the upper bottle body 1 through the air hole 47, and the bottle cap is opened. At 7 o'clock, there is a phenomenon of ink sticking or even dripping, which affects the normal use of the ink bottle. It can be seen that the present invention utilizes the second sealing member 71 and the third sealing member 72 on the cap 7, and when the cap 7 is closed, a sealed separate space is formed inside the bottle 3, thereby effectively preventing the ink in the bottle from being transported during transportation. The ink bottle is inverted or subjected to strong vibration to cause spillage, and the material is environmentally friendly.

More preferably, since the air pressure in the bottle 3 is increased due to an increase in the outside air temperature during the placing or transportation of the ink bottle, the volume of the bottle 3 is expanded, and the initial position of the upper bottle 1 before the pressing is changed, thereby The pressing stroke of the upper bottle body 1 is increased, which causes the ink to overflow during the ink filling process. Therefore, in this embodiment, a limit structure is required to define the stroke of the upper bottle body 1. Specifically, the sidewall of the lower bottle body 2 defines a limiting hole 22, wherein the limiting hole 22 is an elongated hole, and the length direction thereof is consistent with the moving direction of the upper bottle body 1, and the upper bottle body 1 A limiting post 11 is provided to cooperate with the limiting hole 22 . Therefore, the initial position and the end position of the movement of the upper bottle body 1 are defined by the cooperation of the limiting hole 22 and the limiting column 11, thereby preventing the pen from being in the process of injecting the ink due to the excessive pressing stroke of the upper bottle body. The problem of ink spillage.

Further, since the influence of the rotational interference between the respective screw connection structures is considered, it is necessary to provide a rotation stop on the base 5 for preventing relative rotation between the bottle liner 3 and the lower bottle body 2. Department (not shown in the figure).

More preferably, the first sealing member 46 is provided as a sealing ring and is disposed around the outer circumference of the region where the air hole 47 is located. Such a design can close the first sealing member 46 to the end surface of the ink pen tail, effectively reducing the air between the ink pen and the support base 41 into the bottle liner 3 during the insertion of the ink pen into the support base 41, thereby causing the bottle The change of air pressure in the gallbladder 3 affects the effect of ink return and ink injection. Further, the inner wall of the support base 41 is provided with a plurality of guiding blocks 48 for guiding the insertion of the ink pen body to ensure that the liquid injection hole on the tail of the ink pen is aligned with the upper end of the needle tube 44 for convenient insertion; There is a gap between the guiding blocks 48, which facilitates the air between the ink pen and the support base 41 to be discharged to the outside during the insertion of the ink pen into the support base 41.
