Embodiment mode 1: as shown in fig. 1 to 4, the ink 2 is stored in the inner cavity of the ink storage pen holder 1, one end of the ink storage pen holder 1 can be movably inserted with the writing pen holder 3, the writing scroll core 4 is arranged in the writing pen holder 3, one end of the writing pen core 5 is inserted into the writing scroll core 4, and the other pen point end is exposed. Still be provided with fluid infusion package core 6 in the grafting end of storing black pen-holder 1, the pen point end of writing refill 5 can correspond inserts the fluid infusion package core 6 outside, and the inboard of fluid infusion package core 6 is connected with breather and keeps apart ink 2, passes breather's transition and draws water core 7 one end and insert fluid infusion package core 6, the other end and ink 2 intercommunication, forms the fluid infusion structure of gas-liquid circulation balanced type package core.

As shown in fig. 5 and 6, the air interchanger of the present embodiment includes a first air interchanger 8 and a second air interchanger 9 which are butted, an air chamber 10 is formed between the first air interchanger 8 and the second air interchanger 9, the first air interchanger 8 is connected with the fluid infusion winding core 6, a ventilation groove 11 is formed between contact surfaces of the first air interchanger 8 and the transition water guide core 7 to communicate with the air chamber 10, and the second air interchanger 9 is provided with a ventilation small hole 12 to communicate with the air chamber 10 and the ink 2. Typically, there are three venting grooves 11 of the first venting member 8 and two venting apertures 12 of the second venting member 9, all evenly distributed around the central axis.

In the embodiment, when the pen is not used for writing and is in a splicing state, the pen point end of the writing pen core 5 is inserted into the outer side of the liquid supplementing scroll core 6, the ink 2 in the ink storage pen holder 1 is introduced into the liquid supplementing scroll core 6 by the transitional water introducing core 7, and then the ink 2 in the liquid supplementing scroll core 6 is introduced into the writing scroll core 4 by the writing pen core 5 for supplementing ink. When the ink 2 flows out, the air pressure in the inner cavity of the ink storage penholder 1 is reduced, air can be supplemented from the air chamber 10 through the small air holes 12 of the second air exchange piece 9, the air in the liquid supplementing wrapping core 6 enters the air chamber 10 through the air permeable groove 11, the air-liquid circulation balance is realized, and the supplementary ink supply of the writing wrapping core 4 can be continuously filled. Moreover, if the ink 2 in the ink storage pen holder 1 is severely vibrated due to shaking and the like, the ink 2 only slightly enters the air chamber 10 from the small air holes 12, and the ink cannot leak or be thrown out.

When writing is needed, as shown in fig. 7, the writing penholder 3 is pulled out from the ink storage penholder 1 in a split manner, the writing process is like a common scroll core type water color pen, the pen point of the writing pen core 5 discharges ink, and the writing scroll core 4 always obtains supplementary ink supply, so that the ink is abundant, the liquid discharge is stable, and the using effect is good.

Embodiment mode 2: as shown in figure 8, the ink 2 is stored in the inner cavity of the ink storage penholder 1, a liquid supplementing scroll core 6 is arranged in one end of the ink storage penholder 1, one end of the writing pen core 5 is inserted into the outer side of the liquid supplementing scroll core 6, and the other pen point end is exposed. The inner side of the liquid supplementing rolled core 6 is connected with a ventilation device to isolate ink 2, one end of a transition water leading core 7 which passes through the ventilation device is inserted into the liquid supplementing rolled core 6, and the other end of the transition water leading core is communicated with the ink 2, so that a gas-liquid circulation balanced type rolled core liquid supplementing structure is formed.

Similarly, the air interchanger of the embodiment comprises a first air interchanger 8 and a second air interchanger 9 which are butted, an air chamber 10 is formed between the first air interchanger 8 and the second air interchanger 9, the first air interchanger 8 is connected with the liquid supplementing rolled core 6, an air ventilation groove 11 is formed between the contact surfaces of the first air interchanger 8 and the transition water guiding core 7 to be communicated with the air chamber 10, and the second air interchanger 9 is provided with an air ventilation small hole 12 to be communicated with the air chamber 10 and the ink 2.

The writing pen core 5 of the embodiment is fixed and inserted with the liquid supplementing scroll core 6, and a writing pen holder part is not additionally designed. The ink 2 in the ink storage penholder 1 is introduced into the liquid supplementing roll-up core 6 through the transition water introducing core 7, the air pressure of the inner cavity of the ink storage penholder 1 is reduced while the ink 2 flows out, air can be supplemented from the air chamber 10 through the small air holes 12 of the second air exchange piece 9, the air in the liquid supplementing roll-up core 6 enters the air chamber 10 through the air ventilation groove 11, air-liquid circulation balance is achieved, and the ink of the liquid supplementing roll-up core 6 is abundant. When writing is needed, the pen point of the writing pen core 5 discharges ink, the liquid discharge is stable, and the using effect is good.

Because the writing pen core 5 and the liquid supplementing roll-up core 6 of the embodiment are relatively fixed, the writing pen core 5 can be in various forms, a fiber head pen core is adopted as shown in fig. 8, and a crystal head pen core as shown in fig. 9 can be usually adopted to realize different writing and drawing effects.
