Embodiment 1

[0041] Design two circular grooves along the outer periphery of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two rabbit hair fiber needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively, and the distance between the head of the fiber hair needle and the head of the round hoop pen is 0.8mm. Inject a certain concentration of paint into the micro-liquid supply instrument, and draw an ultra-fine ultra-thin film with a width of 15.84 μm and a thickness of Figure 8 .

Embodiment 2

[0043]Design two circular grooves along the outer circumference of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two stone badger hair needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively. The head of the fiber hair needle is 1mm away from the head of the round hoop pen. A certain concentration of paint was injected into the micro-liquid supply instrument. Under the condition that the liquid supply rate was 1 μL / min, the tips of the two stone badger hair needles were in contact with the substrate, and the angle was 30°, the ultra-thin coating with a width of 35.45 μm and a thickness of Figure 9 .

Embodiment 3

[0045] Design two circular grooves along the outer circumference of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two polymer fiber hair needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively, and the distance between the head of the fiber hair needle and the head of the round hoop pen is 1.2mm. A certain concentration of paint is injected into the micro-liquid liquid supply instrument. Under the condition that the liquid supply speed is 1 μL / min, the tips of the two polymer hairs are in contact with the substrate, and the angle is 90°, a superplastic with a width of 49.02 μm and a thickness of Figure 10 .

Abstract

The invention relates to the field of microscale liquid infiltration device, in particular to a pen type liquid guiding and infiltration device. The pen type liquid guiding and infiltration device comprises a water supplying pipe (1), a pen inner tongue liquid transfer pipe (2), a circular hoop type pen head (3) and fiber brush needles (4), wherein two circular-arc-shaped grooves (21) are formed in the pen inner tongue liquid transfer pipe (2) in the periphery, and the fiber brush needles (4) are fixed in the circular-arc-shaped grooves (21) at the liquid discharging end of the pen inner tongue infusion pipe (2); the pen inner tongue liquid transfer pipe (2) penetrates through the circular hoop type pen head (3), and side wall openings of the circular-arc-shaped grooves (21) face a liquidguiding groove (31) of the inner wall of the circular hoop type pen head (3).The pen type liquid guiding and infiltration device is simple in the principle, easy to realize, capable of effectively solving infiltration problem of the microscale liquid in a microscale liquid supplying system, and is of great importance in the development of the research and production of novel ultrathin films with high-quality.

Description

technical field [0001] The invention relates to the field of trace liquid infiltration devices, in particular to a pen-type liquid guide and infiltration device. Background technique [0002] Under normal circumstances, pens cannot draw lines on the surface of flat glass or silicon wafers, and even if they do, they will be drawn intermittently and irregularly. [0003] The distance between the inner tongue of the existing pen and the inner ring of the hoop type pen is on the order of microns, and its size directly affects that most of the trace liquids are gathered in the two grooves. [0004] The gap between the inner tongue of an ordinary pen and the metal ring of the nib is just a tubular gap with a bevel (the thickness is generally 500-800 μm). Under the action of capillary function, the liquid will be dispersed to all parts of the metal inner ring. The head of the metal nib has a slender slit about 300-500 μm wide to connect with the ball head of the nib (the ball hea...
