Embodiment

[0021] Embodiment: a liquid pen, including a penholder, a tail plug, an ink-absorbing pen tip, a sponge and a pen cap; the sponge is located in the lower cavity of the penholder, one end of the ink-absorbing pen tip is located in the sponge, and the other end is located outside the penholder; the inside of the sponge forms a A spherical cavity, one end of the ink-absorbing nib is located in the spherical cavity, and the other end is located outside the penholder; the volume of the spherical cavity is V;

[0022] It also includes a partition, a first ink storage chamber, a second ink storage chamber and an elastic cover;

[0023] The partition divides the upper cavity of the pen holder into a first ink storage cavity and a second ink storage cavity;

[0024] Let the volume of the first ink storage chamber be V1, and the volume of the second ink storage chamber be V2;

[0025] V1 is 10 times of V2; V2 is 3 times of V;

[0026] A hole is provided on the partition, and an elasti...

Abstract

The invention discloses a liquid pen which comprises a pen holder, a tail plug, an ink suction pen point, a sponge and a pen cap. The sponge is located in a cavity in the lower portion of the pen holder. One end of the ink suction pen point is located in the sponge, and the other end of the ink suction pen point is located on the outer portion of the pen holder. A spheroidal cavity is formed in the sponge, one end of the ink suction pen point is located in the spheroidal cavity, and the other end of the ink suction pen point is located on the outer portion of the pen holder. The volume of the spheroidal cavity is set as V. A partition plate, a first ink storage cavity, a second ink storage cavity and an elastic cap are further included. A cavity in the upper portion of the pen holder is divided into the first ink storage cavity and the second ink storage cavity by the partition plate. The volume of the first ink storage cavity is set as V1, and the volume of the second ink storage cavity is set as V2. Fonts are uniform in weight all the time in the writing process by means of the liquid pen.

Description

technical field [0001] The invention relates to a liquid pen. Background technique [0002] figure 1 It is a schematic diagram of the structure of an existing liquid pen, mainly including a pen holder, a tail plug, an ink-absorbing nib, a sponge, an ink storage cavity, and a cap; the principle of this liquid pen is that the ink in the ink storage cavity flows into the sponge body, and when the sponge body When the infiltrated ink is saturated, the ink in the ink storage chamber will no longer flow into the sponge, so that the sponge can supply ink to the ink-absorbing nib relatively stably, but there is a big problem that with the ink in the ink storage chamber As the upper hydraulic pressure decreases, the ink flowing into the sponge will become less and less, so there will be more ink in the ink storage cavity at the beginning of use, and the liquid pen only needs to use a small force to spit out a lot of ink, but later storage When the ink in the ink cavity is getting l...
