Problems solved by technology

[0002] Whiteboard markers are indispensable larger utensils in teaching, and are also office supplies commonly used in offices. Existing whiteboard markers mainly adopt ink-absorbing fibers to store ink in structure. This mode mainly has the following deficiencies: one is to store ink The capacity is limited. Second, the ink supply efficiency is low. In the continuous writing process, the ink often breaks and the writing is not smooth. The third is that the ink cannot be added, because when the ink is used up, the nib will dry and the ink will break. It is also difficult to restore the ink absorption ability of the ink
Therefore, in daily use, you need to stop for a while and wait for the ink supply to continue to use. To verify whether the ink is supplied, many users will use a pen to draw random lines on the whiteboard, and continue to use it after they can draw continuous and clear lines. Affect work efficiency and the user's thinking, but also affect the user's emotions

Embodiment Construction

[0024] Such as figure 1 and figure 2 As shown, a pen with an ink storage cavity is mainly composed of a pen holder 1, a pen cap 2, a refill 3 and ink. The pen holder is hollow, and the ink is stored in the inner hole of the pen holder. One end connects to the pen cap.

[0025] Such as figure 2 and Figure 5 As shown, the described pen with an ink storage chamber also includes an ink delivery tube 5, an ink delivery device and a piston 6 arranged in the pen cap.

[0026] Such as Figure 4 As shown, a pen core fixing hole is provided along the central axis of the nib 4, and the pen core is inserted into the pen core fixing hole from outside to inside to fix; the pen core fixing hole protrudes to the direction of the pen cap to form a pen core fixing column 41, and the pen core is fixed The edge of post toward one end of the pen cap protrudes inwardly to form a pen core stop lug 42, and the diameter of the inner hole of the pen core stop lug is less than the diameter of th...

Abstract

The invention discloses a pen provided with an ink storage cavity. The pen mainly comprises a pen holder, a pen cap, a refill and ink, wherein the pen holder is hollow; the ink is stored in an inner hole of the pen holder; one end of a pen body shrinks to form a pen point, and the other end is connected with the pen cap. Ink is supplied to the ink storage cavity through a piston, thereby improving the ink supply condition, reducing the ink shortage phenomenon and enabling writing to be relatively smooth; and ink can be added for a plurality of times, thereby prolonging the service life of a whiteboard marker.

Description

technical field [0001] The invention relates to a pen with an ink storage cavity for writing on a whiteboard, which belongs to the optimization technology of the whiteboard pen. Background technique [0002] Whiteboard markers are indispensable larger utensils in teaching, and are also office supplies commonly used in offices. Existing whiteboard markers mainly adopt ink-absorbing fibers to store ink in structure. This mode mainly has the following deficiencies: one is to store ink The capacity is limited. Second, the ink supply efficiency is low. In the continuous writing process, the ink often breaks and the writing is not smooth. The third is that the ink cannot be added, because when the ink is used up, the nib will dry and the ink will break. It is also difficult to restore the ink absorption ability of the ink. Therefore, in daily use, you need to stop for a while and wait for the ink supply to continue to use. To verify whether the ink is supplied, many users will us...
