An inner thread 18 is cut on the inner peripheral surface of the end portion of the shaft body 4 on the opposite side to the side where the outer thread 17 is formed, and an outer thread 19 formed on the outer peripheral surface of the front end portion of the ink cartridge 3 is screwed there (refer to FIG. 2, 3, 10). In this way, the ink cartridge 3 can be attached to and detached from the shaft body 4 and can be replaced. Furthermore, preferably, the thread direction of the combination of the external thread 17 of the shaft body 4 and the internal thread 20 of the nib holder 2 is opposite to the thread direction of the combination of the internal thread 18 of the shaft body 4 and the external thread 19 of the ink tank 3 . In this case, for example, when the ink cartridge 3 is replaced, the screw connection between the shaft body 4 and the pen tip holder 2 can be prevented from loosening when the ink cartridge 3 is screwed into the shaft body 4 .

The ink cartridge 3 is sealed by the push-open stopper 21, and the push-open stopper 21 is pushed and opened as it is attached to the shaft body 4, thereby opening the stopper. That is, inside the shaft body 4 , a push-open cylinder 22 (refer to FIG. 10 ) for pushing the push-open plug 21 to open when the ink cartridge 3 is connected is disposed. The push-open cylinder 22 is erected at the center of the cylindrical portion 23 formed on the inner peripheral surface of the shaft body 4 , and allows the ink flowing from the ink cartridge 3 to circulate. Also, in the shaft body 4 The above-mentioned plug 25 (see FIG. 3 ) is fitted into the front end opening.

The bolt 25 is a dish-shaped body with a flange as shown in FIG. 9 , a hollow cylinder 27 is formed in the center through a circular base 26 , a hollow convex portion 28 is extended in the center of the hollow cylinder 27 , and a hollow cylinder 28 is formed. The hollow convex portion 28 penetrates to the ink flow hole 29 of the hollow cylinder 27 . In addition, a pair of ink grooves 30 penetrating in the longitudinal direction from the hollow cylinder 27 to the circular base 26 are usually formed symmetrically, for example. An adjustment cylinder 31 is fitted into the hollow cylinder 27 (see FIGS. 3 and 5 ). At this time, an ink storage space 32 is formed in the adjustment cylinder 31 by moving the inner top surface of the adjustment cylinder 31 away from the upper end surface of the hollow convex portion 28 . In addition, the code|symbol 33 of FIGS. 2 and 3 represents a seal ring.

In a preferred embodiment, the pen nib formed by the nib 1 and the nib holder 2 is set as an independent part, which can be replaced. In this case, by replacing the nib, not only can it be used for a long time, but also by preparing different types of nibs 1 (wool, horsehair, raccoon hair, etc.) commodity value.

As shown in FIG. 4 , when the water brush of the present invention constituted above is not in use, the pen tip 1 is accommodated in the cover 5 . The inner thread 16 on the side of the closing plate 7 of the cover 5 enables the cover 5 to be screwed to the shaft body 4 . At this time, the sealing protrusion 13 of the cover 5 is tightly fitted into the ink flow hole 29 of the plug 25, thereby preventing the leakage of ink (refer to FIG. 4). The pen tip 1 in this state is separated from the ink supply path, exposed to outside air through the vent window 12 of the cover 5 to be dried, and thereafter maintained in this dry state. Therefore, there is no possibility that the pen tip 1 is damaged or moldy due to the continuous state of moisture.

In use, the cover 5 is removed from the shaft body 4 and the nib holder 2 is removed from the cover 5 , and the outer thread 17 of the shaft body 4 is screwed into the inner thread of the nib holder 2 The grooves 20 are formed, whereby the pen tip holder 2 is attached to the shaft body 4 (states in FIGS. 1 and 3 ). In this way, the ink is supplied to the pen tip 1 through the ink circulation path to be described later, so that writing can be performed. When writing is stopped or when the pen is temporarily stopped, the cap 5 is covered and attached to the pen tip 1 in a state where the pen tip holder 2 is attached to the shaft body 4 . Then, when writing is stopped, the reverse operation is performed to return to the state shown in FIG. 4 .

Next, the flow path of the ink of the water brush of the present invention configured as above will be described. If the cassette 3 originally sealed by the push-release bolt 21 is screwed into the shaft body 4 , the top surface 21 a of the push-open bolt 21 of the cassette 3 sealed by the push-open bolt 21 will be pushed open by the shaft body 4 . 22 (refer to Figure 3). Since the top surface 21a of the push-open pin 21 is only thinly connected around it, it does not require much force to push it open. As the push-release plug 21 is pushed open, the ink in the ink cartridge 3 flows into the ink chamber 35 through the push-open cylinder 22, and the place is filled (refer to FIG. 5).

The ink in the ink chamber 35 rises in the ink groove 30 of the plug 25 to fill the ink storage space 32 of the adjustment cylinder 31 , flows from the hollow convex portion 28 to the ink circulation hole 29 , and flows into the space between the pen nib base 6 and the plug 25 The ink supply space 8 (refer to Figures 3 and 5). Thereafter, the ink reaches the pen tip 1 through the ink supply path 10 formed between the outer peripheral surface of the pen tip base 6 and the inner peripheral surface of the pen tip holder 2, and wets the pen tip 1 (see FIGS. 3 and 5 ).
