Abstract

An anti-overflow fluid injecting bottle comprises: a bottle body (1), a needle cylinder (2), a needle seat (3) and a needle tube (4); when an ink pen is added with ink, an elastic closure center hole at the tail of the pen is aligned to the needle seat (3), the needle tube (4) is inserted into a pen barrel, the needle seat (3) is pressurized downwardly to decrease the air pressure inside the bottle body (1), so that the air pressure inside the bottle body is lower than the air pressure inside the pen barrel of the ink pen, and therefore, an ink returning motion is completed; when the pressure of the ink pen upon the needle seat (3) is removed, the needle seat (3) automatically rises under the action of a pressure spring, and at the same time, the pen barrel of the ink pen is kept in connection with the needle tube (4) to enable the air pressure inside the bottle body (1) to rise, so that the air pressure inside the bottle body (1) is higher than the air pressure inside the pen barrel of the ink pen, and therefore, an ink filling motion is completed. The anti-overflow fluid injecting bottle achieves integration of the ink returning and filling motions, and facilitates the use of users.

Abstract

A pen ink sac capable of ink-filling and ink-suction, comprising an ink-storing sac (1), a pushing rod (2), and a locking lid (3). Separately disposed on the pushing rod and the locking lid are a projecting strip (221) and a recessed groove (321) that match one another. By twisting the pushing rod axially, the position matching between the projecting strip on the pushing rod and the recessed groove on the locking lid can be adjusted, thereby switching the method for replenishing ink into the pen sac. The pen sac is capable of ink-filling and ink-suction, and is easy to operate and adaptive.

Abstract

A liquid filling bottle, including a bottle body (1), a fixing support (2), a air compressing device (3), a water filling pipe (4) and a pipe cover (5). The bottle body comprises a bottle neck (11), on which the fixing support is fixed, and one end of the fixing support forms a cavity (22) in which the air compressing device is fixed. One end of the water filling pipe is fixed in the inner of the bottle body and communicated with the external of the bottle body. The pipe cover is fixed and sleeved on the fixing support which is provided with a through hole (23), and the air compressing device is fixed in the bottle body through the through hole. The fixing support is provided with an air groove (27) which is communicated with the external of the fixing support. The air compressing device comprises a supporting base (34) for sealing the air groove. The liquid filling bottle can effectively avoid the ink therein to leak due to environmental changes, and is simple in structure, convenient to operate and inexpensive in cost.

Abstract

A liquid-filling pen comprises a pen holder (1), a pen neck (2), a core seat (3), a liquid-guiding part (4), a tail cover (5), and a pen cap (7). One end of the pen holder (1) is formed with a chamber (12) having an opening, and the opposed end is provided with a locking part (14) having an opening end. The tail cover (5) is fastened at the opening of the chamber, and the pen neck (2) is fastened at the opening end of the holding part (14). The pen cap (7) can be fastened on the pen neck (2). The liquid-guiding part (4) is fixedly provided on the core seat (3) and is placed inside the chamber (12). The chamber (12) has a separating wall (123) which is provided with a hole for communicating the chamber (12) with the locking part (14). The locking part (14) has a liquid-sealing part (144) for sealing the hole, and the liquid-sealing part is provided with a through hole (1441). The core seat is fixedly connected to the liquid-sealing part. The liquid-filling pen can effectively prevent the liquid in a liquid storing tube from leaking and back flowing caused by the excessive liquid-filling amount. The liquid-filling pen has low cost, and it can be operated conveniently.

Abstract

An erasable board structure comprises a face board mechanism (1), an erasing mechanism (2) and a writing belt member (14). The writing belt member surrounds a surface of the face board mechanism. The erasing mechanism includes a trough body (22), in which an end of the face board mechanism covered by the writing belt member is placed. Furthermore, the erasable board structure comprises a drying mechanism (3) arranged to be adjacent to the erasing mechanism at one side of the face board mechanism. The erasable board structure of the invention can solve such a problem that it is necessary to erase an ink writing on a white board frequently by hand during use of the white board, and can save time and effort.
