Detailed Description

The following detailed description of the invention is provided in connection with the drawings.

Embodiment 1 is that the utility model provides a pen adopts dark point pen structure to make a modified pen that can absorb ink in succession

An improved pen capable of continuously absorbing ink comprises a pen point 1 and a pen holder 16, wherein a pen cap 8 is arranged outside the pen point 1 and used for protecting a pen point 7; the upper end of the pen holder 16 is provided with a spring retainer ring pipe 20 and a piston rod button protection cover 34. A pen tongue 5 is arranged in the pen head 1, and the pen tongue 5 is connected with a pen point 7; the one-way valve body 9 is fixedly connected with the penholder 16 into a whole and is positioned at the lower end of the penholder 16, and the one-way valve body 9 is installed in the pen point 1. The one-way valve body 9 is provided with an exhaust pipe mounting groove 11, and the exhaust pipe mounting groove 11 extends into the penholder 16 and is communicated with the ink cavity. One end of the exhaust pipe 15 is installed in the exhaust pipe installation groove 11, but the main part of the exhaust pipe is located in an ink cavity in the pen holder 16; the piston device is arranged at the upper part of the penholder 16; the shaft 16 and the piston rod button protecting cap 34 are not directly connected, but the shaft 16 and the piston rod button protecting cap 34 are connected to the spring retainer ring 20 to be connected, and the piston assembly is fixed by the spring retainer ring 20. The specific structure is seen in the utility model relates to an improved installation process of a pen capable of continuously absorbing ink.

The pen components are first customized according to fig. 1-5 and then installed as follows:

firstly, the pen point 7 and the pen tongue 5 are arranged in the pen point 1. Then, a little of proper adhesive is coated in the middle of the exhaust pipe installation groove 11 on the check valve body 9, most of the exhaust pipe 15 is inserted into the penholder 16 through the exhaust pipe installation groove 11, the rest part of the exhaust pipe 15 is pressed into the exhaust pipe installation groove 11, one end of the exhaust pipe 15 slightly extends out of the exhaust pipe installation groove 11 but does not exceed the check valve body groove 38, and therefore excessive adhesive can be prevented from entering the exhaust pipe 15 to block the exhaust pipe 15 during installation. The check valve body recess 38 also provides an exhaust passage for the exhaust pipe 15 to exhaust. Then, the external screw thread 10 of the one-way valve body 9 which is connected with the penholder 16 into a whole is coated with proper adhesive, and a gap between the exhaust pipe mounting groove 11 and the exhaust pipe 15 is coated with a little more, so that the sealing is prevented from being untight. Screwing the inner thread 3 of the pen head and the outer thread 10 of the valve body of the one-way valve tightly, enabling the lower end face 17 of the pen holder to be tightly attached to the upper end face 4 of the pen head, and then erasing the extruded redundant adhesive; at this time, the tongue water guide tail 6 is installed in the tongue water guide tail installation hole 13. Then the pen cap 8 is covered, so that the pen point convex ring 2 is tightly sleeved in the pen cap 8, and the pen cap 8 is tightly attached to the lower blocking surface 36 of the pen point.

The piston rod 26 is sleeved with the spring 30, and then the spring retaining ring 20 is sleeved on the piston rod installation hole 22 after passing through the piston rod installation hole 22, and the spring 30 is limited between the spring retaining ring inner retaining ring 21 and the piston rod pressing cover 29 due to the action of the spring retaining ring inner retaining ring 21 and the piston rod pressing cover 29. The piston rod 26 and the piston rod pressing cap 29 constitute a piston rod button. Then the piston head 31 is sleeved, the piston rod convex ring 27 is installed in the piston head 31, the piston head retaining ring 32 is installed behind the piston head 31, and the U-shaped groove 33 of the piston head retaining ring is clamped at the narrowest part 28 of the piston rod, so that the piston head 31 cannot fall off when moving up and down, and the service life of the piston head 31 is prolonged.

Then, a solid check valve ball 14 made of metal is arranged in a penholder 16, a piston head 31 in a piston device with a spring retaining ring pipe 20 is inserted into the penholder 16 from the upper part of the penholder 16, external threads 23 at the lower end of the spring retaining ring pipe and internal threads 18 at the upper end of the penholder are screwed tightly, so that an upper end face 19 of the penholder is tightly attached to an outer retaining ring 25 of the spring retaining ring pipe, and internal threads 35 of a piston rod button protective cover on a piston rod button protective cover 34 and external threads 24 at the upper end of the spring retaining ring pipe are screwed in place. An improved pen with continuous ink absorption is thus obtained.

After the adhesive is solidified, the pen can be normally used. When sucking ink, firstly, the piston rod button protective cover 34 is screwed out, then the pen cap 8 is pulled out, then the pen is held by one hand, the pen head 1 is downward, then the piston rod button consisting of the piston rod 26 and the piston rod pressing cover 29 is pressed down by a thumb, the piston rod 26 drives the piston head 31 to move downward, part of air in the pen holder 16 is discharged from the pen head 1 through the exhaust pipe 15, then the pen head 1 is immersed in ink, then the piston rod button is released by the thumb, the spring 30 drives the piston rod button and the piston head 31 to move upward to generate vacuum, and then the ink is automatically sucked into an ink cavity and a piston cavity through two channels of the one-way valve cavity 12 and the exhaust pipe 15. Since the solid metal ball is used as the check valve ball 14, the density of the check valve ball 14 is much higher than that of the ink, and therefore the check valve ball is easy to fall into the check valve chamber 12, thereby playing the role of a check valve, and preventing the ink from being discharged through the check valve chamber 12 when absorbing the ink. Repeated pressing and releasing of the piston rod button can continuously exhaust and suck ink, so that the ink slowly fills the whole ink cavity and part of the piston cavity. After blotting, the piston rod button protective cover 34 is screwed on, and then the pen cap 8 is covered. The pen can then be used for normal writing.

The utility model discloses a set up blast pipe mounting groove 11 on check valve body 9 to extend to and link up with the ink chamber in the pen-holder. Compared with an exhaust pipe mounting hole, the exhaust pipe 15 is more convenient to mount and simpler to seal, and two sealing surfaces are arranged between the one-way valve body 9 and the pen point 1, so that the sealing reliability is high.

The valve body 9 of the one-way valve is also manufactured in two parts, and the outer part of the valve body of the one-way valve is made of hard plastics or metal which is made of the same material as the pen holder; the contact surface of the inner part and the check valve ball 14 and the contact part of the inner part and the water guide tail of the pen tongue can be made of elastic bodies, such as rubber, silica gel and the like, and the outer wall of the elastic body is provided with an exhaust pipe mounting groove or an exhaust pipe mounting hole. A better sealing surface is obtained when this part made of elastomer is in contact with the check valve ball 14.

Two check valve beads 14 can be added to make it easier for one of them to fall into the check valve chamber 12 when sucking ink, thus making it easier to perform the function of a check valve.

The utility model discloses blast pipe 15 chooses tiny tubular metal resonator for use to do the blast pipe, for example, the tubular metal resonator of optional internal diameter 0.05-0.5 millimeter, and modern processing technology can be very thin with the tubular metal resonator is done, only 0.31 millimeter if the syringe needle external diameter of 1 ml syringe, and the internal diameter is only 0.15 millimeter. However, the inner diameter of the exhaust pipe 15 cannot be too small, and the resistance to sucking and exhausting air is large and clogging is liable to occur.

The exhaust pipe made of fine metal materials is adopted, so that the installation space is small, the adsorption effect of the exhaust pipe on ink is improved, and the ink is difficult to leak through the exhaust pipe. When the pen is used, no matter whether ink exists in the exhaust pipe after ink absorption, a user always pours the pen, and as long as the exhaust pipe positioned in the ink cavity contacts the ink, the capillary action enables the exhaust pipe to be completely filled with the ink. The use of these small vent tubes can block the passage of ink or air through the vent tube during writing. Although the gap between the tongue water-drawing tail and the tongue water-drawing tail mounting hole has capillary action, the length of the gap is far less than that of the exhaust pipe, and the resistance generated by the capillary action is far less than that of the exhaust pipe. Therefore, during writing, the ink output and air exchange are always performed through the tongue water guide tail mounting hole 13, not the air exhaust pipe 15. Only when absorbing ink, the air is discharged through the exhaust pipe; ink is sucked in through the exhaust pipe 15 except for one part through the water guide tail mounting hole 13 of the pen tongue.

The utility model discloses set up spring catch ring pipe lower extreme external screw thread 23 and spring catch ring pipe upper end external screw thread 24 respectively at spring catch ring pipe 20's both ends to link to each other with pen-holder 16 and piston rod button safety cover 34 respectively, reducible pen-holder 16's wall thickness improves pen-holder 16's internal diameter, also improves the internal diameter in piston chamber from this, thereby improves displacement and ink storage capacity once. For example, an improved continuous ink-absorbing pen with a pen holder with an outer diameter of 11 mm and an inner diameter of 9 mm, a total length of 125 mm and a piston stroke of 10 mm is adopted, the primary air displacement can reach 635 cubic mm, and the ink storage capacity can reach 2225 cubic mm; according to the invention patent case CN112389113A, a pen capable of continuously absorbing ink is manufactured by using pen holders with the same outer diameter and the same piston stroke, the inner diameter of a piston cavity can only reach 7 mm, if the inner diameter of the ink cavity is the same as the inner diameter of the piston cavity, the ink storage capacity of the manufactured pen is only 1154 cubic mm, and the primary air displacement is only 385 cubic mm; although the inner diameter of the ink cavity can be different from that of the piston cavity, the inner diameter of the ink cavity can also reach 9 mm, and the ink reserve of the manufactured pen is only 1656 cubic mm. It is thus clear that the utility model has stronger practicability.
