Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A whiteboard pen capable of adding ink comprises a hollow tubular pen holder 1, a pen point 2 fixed at the head of the pen holder 1, a pen cap 3 covering the outside of the pen point 2 and clamped and fixed with the pen point 2, a tail cap 4 in threaded connection with the tail of the pen holder 1, an ink storage mechanism 5 installed inside the pen holder 1, an ink absorption core (not shown in the drawing) connected between the pen point 2 and the ink storage mechanism 5, and a spare ink box 6 connected with the ink storage mechanism 5, as shown in figure 1. The ink absorbing core is made of a substance with moisture absorption capacity such as sponge, and can absorb the ink in the ink storing mechanism 5 and provide the ink to the pen point 2, thereby realizing the writing function. After the ink in the ink storage mechanism 5 is used up, the standby ink box 6 can provide emergency ink, so that the white board pen can still write smoothly in a short period.

As shown in fig. 2 and 3, the ink storing mechanism 5 includes a fixing plate 51 fixedly connected to the inner wall of the middle portion of the barrel 1, a fixing ring 52 coaxially and fixedly connected to one side of the fixing plate 51 facing the tail cap 4, two conduits 53 fixedly connected to one side of the fixing plate 51 facing away from the tail cap 4, and an ink tube 54 filled with ink and allowing the fixing ring 52 to be inserted therein. The conduit 53 is inserted into the ink-absorbing core, and the fixing plate 51 is provided with two through holes 511 communicating with the conduit 53, the through holes 511 being located inside the fixing ring 52. Ink in the ink tube 54 can flow into the wick through the through hole 511 and the conduit 53.

As shown in fig. 2 and 3, the end of the ink tube 54 facing the fixing plate 51 has an opening, the fixing ring 52 is attached to the inner wall of the opening, the end of the ink tube 54 away from the fixing plate 51 extends out of the pen barrel 1, and the inner side of the bottom wall is fixedly connected with a square connecting tube 55. The middle part of the bottom wall of the ink tube 54 is provided with a connecting hole 541 which is square and is opposite to the opening of the connecting cylinder 55, and the spare ink box 6 is clamped into the connecting hole 541. The spare ink box 6 is directly connected with the ink tube 54, and the use is quick and convenient. One end of the fixing ring 52 far away from the fixing plate 51 is fixedly connected with an arc-shaped plate 56 which is coaxially arranged, and the central angle of the arc-shaped plate 56 is less than 180 degrees.

The inverted penholder 1 is inserted from bottom to top after the ink is filled in the ink tube 54, the arc-shaped plate 56 is clamped into the ink tube 54, so that the ink tube 54 is guided, the fixing ring 52 is conveniently inserted into the ink tube 54, and the end part of the ink tube 54 is attached to the fixing plate 51. On the one hand, the fixing ring 52 plays a role of preventing ink leakage, and on the other hand, the ink tube 54 is well fixed, and the installation is fast and convenient.

As shown in fig. 4 and 5, the spare ink cartridge 6 includes an ink reservoir 61 and a lead-out portion 62 that are snap-fitted. The leading-out portion 62 includes a prism 621 inserted into the connecting cylinder 55, a connecting plate 622 fixedly connected to an outer side of an end of the prism 621 away from the ink tube 54, and a snap ring 623 fixedly connected to a side of the connecting plate 622 away from the prism 621. The ink reservoir 61 is in the shape of a round box and has an opening on the side facing the lead-out portion 62, and the connecting plate 622 is in the shape of a circle and has a diameter equal to the outer diameter of the ink reservoir 61, so that the connecting plate 622 can completely close the opening of the ink reservoir 61. The snap ring 623 is engaged with the ink storage portion 61 and attached to the inner wall thereof, so that the ink storage portion 61 and the guiding portion 62 can be separated by pulling the two parts, thereby facilitating the filling of ink into the ink storage portion 61.

As shown in fig. 4 and 5, since the outer edge of the cross section of the prism 621 is square and fits into the connector barrel 55, the prism 621 cannot rotate inside the connector barrel 55. The prism 621 is longer than the depth of the connecting cylinder 55 so that the connecting plate 622 is spaced from the ink tube 54 to facilitate the removal of the spare ink cartridge 6. The prism 621 has an ink outlet chamber 6211 and communicates with the ink storage portion 61, an ink outlet 6212 communicating with the ink outlet chamber 6211 is provided on one side wall of the prism 621, and an ink inlet 551 communicating with the ink outlet 6212 is provided on the side wall of the connecting cylinder 55.

During normal writing, the side wall of the prism 621 having the ink outlet 6212 is displaced from the side wall of the connecting cylinder 55 having the ink inlet 551, so that the ink in the spare ink cartridge 6 cannot flow into the ink tube 54. When the spare ink is needed, the tail cover 4 is opened, the white board pen is inverted, the spare ink box 6 is detached and rotated until the ink outlet 6212 and the ink inlet 551 are positioned on the same side, then the spare ink box 6 is inserted upwards, the white board pen is upright, and finally the tail cover 4 is installed, so that the spare ink in the spare ink box 6 flows into the ink pipe 54 to be supplemented, and short-term writing can be performed.

As shown in fig. 1 and 3, the tail cap 4 includes a thread portion 41, a twist portion 42 and a closed end 43 which are fixedly connected in sequence, the thread portion 41 is connected to the inner side of the tail end of the barrel 1 in a thread manner, so that the connection tightness and the quick detachment of the tail cap 4 are ensured. The twisting part 42 is positioned at the outer side of one end of the ink tube 54 extending out of the penholder 1, and a plurality of anti-slip strips are fixedly connected to the outer side of the twisting part 42 in the circumferential direction, so that people can conveniently twist. The closed end 43 has a circular inner cavity into which the ink reservoir 61 is inserted, and the ink reservoir 61 is closely attached to the bottom wall of the circular inner cavity. On the one hand, the spare ink cartridge 6 is well positioned, and on the other hand, the tail cap 4 is not limited by the ink storage part 61 after being twisted. The outer side of one end of the screwing part 42 facing the thread part 41 is connected with a positioning ring 44, and the tail cover 4 cannot rotate continuously after being screwed until the positioning ring 44 contacts with the end face of the penholder 1, so that the positioning function is realized.

The use process comprises the following steps:

when the spare ink needs to be replenished, the tail cover 4 is unscrewed, the white board pen is inverted, the nail is clamped into the gap between the connecting plate 622 and the ink tube 54, the spare ink box 6 is pulled out, the spare ink box is rotated until the ink outlet 6212 and the ink inlet 551 are positioned at the same side, the spare ink box 6 is inserted upwards, the white board pen is arranged, and finally the tail cover 4 is installed, so that the spare ink in the spare ink box 6 flows into the ink tube 54 for replenishing. After the emergency use is completed, the ink in the spare ink cartridge 6 is replenished, and then the ink in the ink tube 54 is replenished.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
