Problems solved by technology

[0002] Although the writing implements on the existing market are complex and changeable in form and complete in variety, they all have the following common shortcomings: 1. The stock of writing ink is too small, and the frequency of changing new pens is very high
2. Due to the structure of the writing instrument itself, if the filling exceeds the capacity that it can bear to store the writing ink, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instruments The liquid capacity is a low-capacity structure
4. Especially a kind of disposable writing instrument of popular type, often because writing ink fluid is used up fast and whole writing instrument is still very new just has to be discarded, thereby the utilization rate of whole writing instrument is very low, cause a lot of waste of resources
However, it was found that during the forward movement of the nib of this type of marking pen, too much liquid often flowed or penetrated into the nib and could not be sucked back in time, or sometimes the air was sucked back and the writing ink was rarely sucked back.
Furthermore, for the writing instrument with a nib with a ball, because it is closed, the liquid that penetrates or is pressed out can hardly be sucked back, so there is still a dripping phenomenon.

Embodiment 1

[0104] Embodiment 1: Referring to Fig. 1, an additional ink reservoir 3 equipped with writing ink 13 is arranged outside the first ink storage chamber 2 equipped with writing ink 13 to be located above the first ink storage chamber 2, and the additional ink reservoir 3 is a fully enclosed structure, which is the preferred structure, which fundamentally ensures that there will be no liquid leakage when the additional ink reservoir 3 is arranged outside the first ink storage chamber 2, and it can be stored for a long time and is not easy to dry .

[0105] The opening device 4 that is used to open (pass through) and guide the writing ink 13 in the additional ink tank 3 outside the first ink storage chamber 2 can be located above the first ink storage chamber 2, and the opening device 4 can be installed on the first ink storage chamber 2. The top of the ink storage chamber 2 can also be made into an integral structure or fixedly connected with the top, and the opening device 4 is ...

Embodiment 2

[0119] Embodiment 2: Referring to Fig. 3, the ink introduction device 42 is arranged in the opening member 41, the ink introduction device 42 can be the ink introduction liquid core 421, and the opening device 4 can also include the opening member 41, the ink introduction liquid core 421 and the Between the opening part 41 and the ink-inducing liquid core 421, a ventilating channel 43 and a leak-proof part 44 are arranged to ensure that the writing ink 13 in the additional ink reservoir 3 is smoothly supplied to the nib 1, making writing smooth and not easy to leak . The leak-proof member 44 can prevent the writing ink 13 in the additional ink reservoir 3 from leaking into the first ink storage chamber 2 , and also facilitates the installation of the ink-leading liquid core 421 in the opening member 41 . The ventilation channel 43 can be a slot or groove structure. The ventilation channel 43 can be arranged on the leak-proof member 44 ; it can also be arranged on the inner si...

Embodiment 3

[0122] Embodiment 3: Referring to Fig. 5 and Fig. 39, at least part of the surface of the bottom 31 of the additional ink reservoir 3 may be threaded 310, and the first ink reservoir 2 extends in the opposite direction of the pen tip 1 to form a socket The bottom of 21 is also provided with threaded shape 210 ′ and can be connected with the threaded shape 310 on the bottom 31 of the additional ink tank 3 . A closing member 33 is provided in the through hole opened in the bottom 31 of the additional ink reservoir 3 to form a concave portion 32, and the closing member 33 may adopt a structure such as a bead or a block. When the writing ink 13 in the additional ink reservoir 3 is needed, the additional ink reservoir 3 is rotated so that the external thread 310 is screwed with the internal thread 210 ′, so that the additional ink reservoir 3 moves along the first ink storage chamber 2 Rotate radially to make the opening member 41 open (open) the bead-shaped sealing member 33, so t...

Description

technical field [0001] The present invention relates to a writing implement, especially such as crayons, felt-tipped pens, fiber-tipped pens, ballpoint pens, fountain pens, highlighters, paint pens, writing pens, markers and other types of writing implements. Background technique [0002] Although the writing implements on the existing market are complex in form and complete in variety, they all have the following common shortcomings: 1, the stock of writing ink is too little, and the frequency of changing new pens is very high. 2. Due to the structure of the writing instrument itself, if the filling exceeds the capacity that it can bear to store the writing ink, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instruments The capacity of the liquid belongs to the structure of low capacity. 3. When the writing tool is stored for a long time, the writing ink in the ink storage chamber will dry naturally and ...
