in the initial state, the air pressure in the ink supply cavity 110 is consistent with the external air pressure, when writing, the ink is transmitted to the pen point through the water guiding core 300, at this time, the ink supply cavity 110 forms negative pressure, and the air in the atmosphere communicating cavity 120 sequentially passes through the first air guide channel 510, the third air guide channel 530, the second air guide channel 520, the ink storage cavity 421, the first ink return gap 428, the ink return channel 427 and the second ink return gap 429 and enters the ink supply cavity 110, so that the balance of the internal air pressure and the external air pressure is realized.
The air in the ink supply chamber 110 may expand or compress due to changes in temperature or air pressure:
when the air in the ink supply chamber 110 contracts, the air in the atmosphere communicating chamber 120 will enter the ink supply chamber 110 through the air guide channel and the ink return channel 427 until the internal and external air pressures are balanced, as in the above case;
when the air in the ink supply chamber 110 expands, the ink in the ink supply chamber 110 will sequentially enter the ink storage chamber 421 through the second ink return gap 429 and the ink return flow passage 427 until the internal and external air pressures are balanced;
when a negative pressure is formed inside the ink supply chamber 110 as writing progresses (or when the internal air contracts due to a change in the external temperature or the like), the ink in the ink reservoir 421 flows back into the ink supply chamber 110 through the first ink return gap 428, the ink return flow passage 427, and the second ink return gap 429 in this order by the dual action of the air pressure and the capillary suction force.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the spirit or scope of the invention.
