Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pen, more particularly to a pen head and a pen. BACKGROUND

[0002] The running water pen was invented by an American, Walter Martin, in the late 19th century, and the Chinese characters have higher requirements for the change of stroke thickness, requiring the ability to change from thick to thin, eight directions of the brush, especially the light and fast start, thick middle and sharp end, and the existing pen does not have such performance ability at all.

[0003] The existing iridium particles are welded at the top of the pen tip as a writing friction part in contact with paper, and the iridium particles are easy to damage and small in size, short in service life, and unable to be passed down.

[0004] The existing pen joint generally adopts a heat treatment process or a mechanical joint. The heat treatment is mainly used for stainless steel joint, which can slightly anneal and soften the stainless steel, thereby reducing the elasticity. The mechanical joint can cause plastic deformation, and the effect is uncertain. Moreover, it is difficult to ensure that the two pieces of the pen tip are completely flat and folded after the joint treatment (not wrong iridium, not wrong tip). The degree of joint after the joint treatment is fixed, and the size of the water flow cannot be adjusted by adjusting the degree of joint.

[0005] The existing pen tongue is connected with the pen barrel by a hard plug-in mode, which is easy to damage.

[0006] The existing ink feeding system is generally divided into three types of disposable ink bag ink feeding (card water ink feeding), immersion ink feeding (standard ink feeder, vacuum, negative pressure, pressing ink bag, pull rod pressing, piston) and drop ink feeding, which is easy to have the problem of ink residue. Moreover, the existing pen does not have a good water feeding system and ink stopping system. SUMMARY

[0056] Embodiment 1:

[0057] Referring to Figures 1-7 The present application discloses a pen head, comprising:

[0058] The pen tongue 1 is provided with a plurality of annular grooves 11 arranged at intervals thereon, and the side wall thereof is axially provided with ink guide grooves 12 communicating with the plurality of annular grooves 11;

[0059] The pen nib is adapted to be arranged around one side of the pen tongue 1 corresponding to the ink guide groove 12, and one end thereof is detachably connected to the ink inlet end of the pen tongue 1, and the other end is provided with an ink guide seam 21 at a position corresponding to the ink guide groove 12;

[0060] The pen holder 4 comprises an arc-shaped fixing piece 41 and an adjusting screw 42, the arc-shaped fixing piece 41 is installed on the outer side surface of the pen nib at the ink inlet end of the ink guide seam 21; a plurality of adjusting holes 211 are provided on both sides of the pen nib corresponding to the ink guide seam 21, a plurality of adjusting screws 42 are correspondingly threaded through the arc-shaped fixing piece 41 and pass through the adjusting holes 211 to be threadedly connected with the pen tongue 1, and the tail ends of the adjusting screws 42 located on both sides of the ink guide seam 21 are inclined towards each other.

[0061] The pen tip includes a fan-shaped pen tip body 2 and an iridium particle 3, the pen tip body 2 is adapted to be arranged outside the pen tongue 1, an arc-shaped fixing piece 41 is installed on the outer side of the pen tip body 2; the ink guide seam 21 is provided with two arcs, the two ink guide seams 21 are both through the inner and outer sides of the pen tip body 2 and symmetrically arranged on both sides of the ink guide groove 12, one end of the two ink guide seams 21 corresponds to the annular groove 11, and the other end of the two ink guide seams 21 is close to each other in the direction of the writing tip of the pen tip; a plurality of adjusting holes 211 are symmetrically arranged on the pen tip body 2 outside the two ink guide seams 21; the iridium particle 3 is fixed on the tip part of the pen tip body 2, and two ink guide seams 301 are arranged on the iridium particle 3 and communicated with the two ink guide seams 21 respectively.

[0062] The pen tongue 1 is made of titanium alloy material, which has low price and excellent performance and has sufficient strength. The pen tip body 2 is made of zirconium-based amorphous alloy or nickel-titanium memory alloy material, and the pen tip body 2 and the iridium particle 3 are integrally formed by pressure casting. The pen tip body 2 made of zirconium-based amorphous alloy has zero plasticity and great elasticity, and has great initial deformation force, so that a perfect linear deformation curve can be obtained, thereby meeting the requirements of the physical and chemical properties of the pen tip. The nickel-titanium memory alloy material has good elasticity and is not easy to break, which is suitable for the requirements of the pen tip.

[0063] The two ink guide seams 21 are both arc-shaped, and the concave surfaces of the two arc-shaped ink guide seams 21 are both directed away from the ink guide groove 12. The design of the two arc-shaped ink guide seams 21 makes the ink flow more smoothly, and has strong ability to change the thickness, which is more suitable for writing of fancy English and Chinese pen strokes and meets the requirements of ergonomics. The ink guide seam 21 and the ink guide seam 301 are both cut by precise slow wire cutting process, so that the cut seam is smooth, neat and without burrs, and writing is more smooth.

[0064] The width of the ink guide seam 301 is not easy to adjust when the pen tip is in the jointing process, and the amorphous alloy has zero plasticity, and the plasticity of the nickel-titanium alloy is also low, so that the pen tip is easily broken in the jointing process. Therefore, the pen tip 4 for adjusting the width of the ink guide seam 301 is further provided. The tail ends of the adjusting screws 42 on both sides of the ink guide seam 21 are inclined to each other, so that when the length of the adjusting screw 42 screwed into the pen tongue part is changed, the part of the pen tip away from the writing tip is fixed, and the part of the pen tip close to the writing tip moves to the direction close to or away from the pen tongue 1, so that the adjusting holes 211 on both sides of the ink guide groove 12 are close to or away from each other, the ink guide seam 21 between the adjusting holes 211 on both sides is closed or opened, the ink guide seam 301 is closed or opened, the width of the ink guide seam 301 is adjusted, and the amount of ink at the pen tip is adjusted, thereby meeting different writing requirements.

[0065] The middle part of the tongue 1 is provided with symmetrical planes, and the pen point body 2 is fixed with arc-shaped connecting plates symmetrically at the end away from the iridium particle 3 to form clamping grooves, and the side end faces of the two arc-shaped connecting plates abut against the two planes of the tongue 1 respectively, so that the pen point body 2 is clamped and fastened with the tongue 1 to prevent rotation between the pen point and the tongue 1.

[0066] As shown in Figures 3-6 The iridium particle 3 is a polyhedron, including an extension surface 31, a large end surface 32 and a small end surface 33 at the two ends of the extension surface 31, a first writing surface 34 arranged opposite to the extension surface 31, and a second writing surface arranged symmetrically on the two sides of the first writing surface 34. The extension surface 31 is a plane, and one end thereof is smoothly connected to the surface of the pen point body 2 away from the tongue 1. The small end surface 33 is arranged perpendicular to the extension surface 31 and is smoothly connected to one side end of the extension surface 31 away from the pen point body. The first writing surface 34 away from the small end surface 33 is inclined to the direction away from the extension surface 31 and is smoothly connected to the large end surface 32. The two ink guide seams 301 penetrate the large end surface 32 and the small end surface 33 in the length direction and penetrate the extension surface 31 and the first writing surface 34 in the depth direction.

[0067] The second writing surface includes a first surface 351, a second surface 352, a third surface 353, a fourth surface 354 and a fifth surface 355 connected in sequence. One side end of the first surface 351 is connected to the extension surface 31, and the other side end is inclined to the direction away from the first writing surface 34. The included angle between the first surface 351 and the extension surface 31 is 135°. The second surface 352 is arranged perpendicular to the extension surface 31 and is connected to the large end surface 32 at one end and is inclined to the direction close to the small end surface 33 at the other end. The included angle between the second surface 352 and the first surface 351 is 135°, and the included angle with the small end surface 33 is 98.5°. The third surface 353 and the fourth surface 354 are arranged side by side and connected to the side of the second surface 352 away from the large end surface 32. The included angle between the third surface 353 and the first surface 351 is 156.6°, the included angle between the third surface 353 and the second surface 352 is 155.8°, and the included angle between the third surface 353 and the small end surface 33 is 105.9°. The included angle between the fourth surface 354 and the third surface 353 is 156.6°, the included angle between the fourth surface 354 and the second surface 352 is 165.2°, and the included angle between the fourth surface 354 and the small end surface 33 is 113.4°. One side end of the fifth surface 355 is connected to the second surface 352, and the other side end is connected to the first writing surface 34. The included angle between the fifth surface 355 and the second surface 352 is 135°, and the included angle between the fifth surface 355 and the first writing surface 34 is 135°. The fifth surface 355 and the first writing surface 34 are both arc surfaces, which are convenient for adjusting the angle during writing.

[0068] The multiple faces of the iridium particle 3 reflect different light colors under light, improving the aesthetic appearance of the iridium particle 3. The multiple writing faces can be used to change the angle and the holding posture of the pen to achieve different pen strokes, which can meet the writing requirements of fancy English and Chinese. The distance between the small end face and the large end face of the iridium particle 3 is 3.6 mm, which makes the overall size of the iridium particle 3 longer, facilitating writing and enhancing the firmness of the iridium particle 3, avoiding damage due to long-term wear and tear, and prolonging the service life of the iridium particle 3.

[0083] Working principle:

[0084] When the rotating shell 73 is screwed to the right in the drawing, the rotating rod 72 is rotated to drive the ink stopper 71 to rotate, and since the ink stopper 71 is in threaded connection with the pen rod 61, the ink stopper 71 is rotated while moving away from the pen tongue 1 along the sliding groove 7211, the ink inlet end of the pen tongue 1 is separated from the ink stop groove 711, the ink inlet groove 12 is communicated with the ink storage cavity 611, and the ink can flow to the pen point along the ink inlet groove 12 for writing. Similarly, when the rotating shell 73 is screwed to the left in the drawing, the rotating rod 72 is rotated to drive the ink stopper 71 to rotate while the ink stopper 71 is rotated to the pen tongue 1 under the guidance of the thread, the ink inlet end of the pen tongue 1 enters the ink stop groove 711, and the passage between the ink inlet groove 12 and the ink storage cavity 611 is closed, so that the ink cannot enter the ink inlet groove 12, thereby achieving the effect of stopping the ink.

[0085] During the reverse screwing process, when the ink inlet end of the pen tongue 1 reaches the bottom of the ink stop groove 711, the axial direction of the ink stopper 71 cannot be displaced, and the ink stopper 71 cannot continue to rotate due to the restriction of the thread, and the rotating rod 72 and the driven ratchet sleeve 75 also stop rotating, if the screwing continues, the rotating shell 73 can still drive the driving ratchet sleeve 74 to rotate, and at the same time, the tooth tip of the driving ratchet tooth slides from the root of the driven ratchet tooth to the tip of the driven ratchet tooth, so that the axial distance between the driving ratchet sleeve 74 and the driven ratchet sleeve 75 increases, the spring 76 is compressed, and under the cooperation of the long strip sliding hole 7511 and the sliding block, the driven ratchet sleeve 75 slides upward relative to the rotating rod 72. When the tooth tip of the driving ratchet tooth reenters the root of the driven ratchet tooth, the spring 76 recovers, and the driven ratchet sleeve 75 reengages with the driving ratchet sleeve 74. When the tooth tip of the driving ratchet tooth reenters the root of the driven ratchet tooth, due to the large diameter change, the driving ratchet tooth and the driven ratchet tooth collide, making a sound, thereby prompting the user that the pen tongue 1 has reached the bottom of the ink stop groove 711, preventing excessive screwing and causing the ink stopper 71 to break under the condition of not being able to see the internal structure.

[0086] When the ink needs to be added, the ink is sucked by a syringe and injected into the ink storage cavity 611 from the ink injection hole 621. A blunt needle is selected for the injection needle to prevent the sharp part of the needle from damaging the sealing rubber plug 62.

[0087] The depth of the adjustment screw 42 in the pen body 4 is changed to adjust the width of the ink guide slot 301 and the amount of ink flow. The pen body 4 cooperates with the ink stop assembly 7 to more accurately adjust the amount of ink flow.
