Description

Technical Field

[0001] The present invention relates to the technical field of writing tools, and more particularly to a push-button valve pen. Background Art

[0002] There is currently a valve pen that supplies ink to the nib for writing. In the pen barrel of this structure, there is a valve opened and closed by the nib. When in use, the nib is pushed to open the valve, so that the ink in the pen barrel wets the nib, thereby achieving writing. However, for this type of valve pen with such a structure, the valve always needs to be pushed open by the nib each time writing, which easily causes wear of the nib. At the same time, there are requirements for the pushing force. For people with relatively small strength, it is very strenuous to operate this type of valve pen. And when pushing the nib slightly harder or too hard, it will cause excessive ink output, and phenomena such as ink overflow are likely to occur at the nib, increasing the consumption of ink, reducing the ink utilization rate and the writing length. Summary of the Invention

[0003] The main object of the present invention is to provide a push-button valve pen to solve the problems of nib wear, difficult operation, and uncontrollable ink output in the prior art.

[0004] To achieve the above object, the present invention provides a push-button valve pen, including a pen tip with a nib, a pen barrel, a valve body, and a valve core, including a pushing mechanism. The pushing mechanism includes a push rod with a cavity, an ink storage tube with a contraction section, a first spring, a second spring, and an oil tube. The push rod and the first spring are sleeved on the pen tip and fixedly arranged in the pen barrel. One end of the ink storage tube is sleeved on one end of the valve body and fixed in the pen tip. One end of the oil tube is fixedly connected to one end of the valve core. The second spring is sleeved on one end of the valve core. The opening and closing of the valve body and the valve core are used to control the ink to enter and exit, and the nib is connected to the other end of the valve core.

[0005] Preferably, the contraction section is arranged at the tail end or the middle of the ink storage tube. The contraction section is provided to achieve the ink output stroke and increase the ink storage capacity at the same time. And arranging the contraction section at the tail end or the middle of the ink storage tube is convenient for the push rod to press, and the manufacturing process is simple.

[0006] Preferably, the ink storage tube is made of PE material. The PE material is used to increase the elastic force provided when the ink tube is pressed.

[0007] Preferably, a stirring member is arranged in the ink storage tube, and the stirring member is used to stir the ink. Arranging the stirring member can stir the viscous ink evenly, which is beneficial to the smooth ink output.

[0008] Preferably, a stirring member is disposed inside the ink storage tube, and the stirring member is sleeved on the oil tube. The stirring member is sleeved on the oil tube to facilitate stirring even in an ink storage tube with a small diameter. Simply by shaking the pen up and down, the ink can be easily stirred evenly.

[0009] Compared with the prior art, the advantages of the present invention lie in the provision of a pressing device. By pressing the pressing rod, the first spring is compressed, and the ink storage tube in the pressing rod is also compressed, causing the oil tube to move forward toward the nib. After the second spring sleeved on the valve core is pressurized, the closed state of the valve core and the valve body is opened, and the ink flows into the nib to achieve writing. Since the pressing rod is used, the nib at the writing end is not pressed, reducing the wear of the nib. At the same time, pressing from top to bottom is labor-saving and convenient. At the same time, the preset forces of the first spring and the second spring can control the ink output evenly, improving the writing length of the valve pen. BRIEF DESCRIPTION OF THE DRAWINGS

EMBODIMENTS

[0011] An embodiment of the present application provides a pressing valve pen to solve the problems of nib wear, laborious operation, and uncontrollable ink output in the prior art.

[0012] The technical solutions in the embodiments of the present application for solving the above problems of nib wear, laborious operation, and uncontrollable ink output are generally as follows: By providing a pressing device, when the pressing rod is pressed, the first spring is compressed, and the ink storage tube in the pressing rod is also compressed, causing the oil tube to move forward toward the nib. After the second spring sleeved on the valve core is pressurized, the valve core is separated from the valve body, opening the ink passage, and the ink flows into the nib to achieve writing. Since the pressing rod is used, the nib at the writing end does not need to be pressed, reducing the wear of the nib. At the same time, pressing from top to bottom is labor-saving and convenient. At the same time, the preset forces of the first spring and the second spring can control the ink output evenly, improving the writing length of the valve pen.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0014] As Figure 1-2 shown, a pressing valve pen includes a pen tip 1 having a pen head 11, a pen barrel 2, a valve body 3, a valve core 4 and a pressing mechanism. The pressing mechanism includes a pressing rod 51 having a cavity, an ink storage tube 52 having a constriction section, a first spring 53, a second spring 54 and an oil pipe 55. The pressing rod 51 and the first spring 53 are sleeved on the pen tip 1 and fixedly arranged in the pen barrel 2. One end of the ink storage tube 52 is sleeved on one end of the valve body 3 and fixed in the pen tip 1. One end of the oil pipe 55 is fixedly connected to one end of the valve core 4. A second spring 54 is sleeved on one end of the valve core 4. The opening and closing of the valve body 3 and the valve core 4 are used to control the ink inlet and outlet. The pen head 11 is connected to the other end of the valve core 4.

[0015] Specifically, the constriction section is arranged at the outermost end of the tail of the ink storage tube 52, and secondly, it is arranged in the middle of the ink storage tube 52.

[0016] Specifically, the ink storage tube 52 is made of PE material.

[0017] Specifically, a stirring member is arranged in the ink storage tube 52, and the stirring member is used for stirring the ink.

[0018] Specifically, the stirring member is sleeved on the oil pipe 55. Preferably, a spring is used as the stirring member, and the structure is simple. As long as the pressing valve pen is shaken up and down, the ink can be easily stirred.

[0019] The working principle of this embodiment is: Press the push rod 51, the ink storage tube 52 and the oil tube 55 in the push rod 51 move downward in the direction of the pen tip 11. The first spring 53 is compressed by the push rod 51 into a contracted state. The ink storage tube 52 in the push rod 51 is also compressed by the push rod 51. The oil tube 55 in the ink storage tube 52 advances toward the pen tip. The second spring 54 sleeved on the valve core 4 is pressed by the oil tube 55 to open the closed part between the valve core 4 and the valve body 3, and the ink flows into the pen tip to achieve writing. When the pressing action of the push rod 51 is released, under the elastic force of the first spring 53 and the second spring 54, the push rod 51, the oil tube 55 and the ink storage tube 52 return to their original states, the valve core 4 and the valve body 3 are hermetically fitted, and the ink outlet channel is closed. Since the push rod 51 is pressed, the pen tip at the writing end does not need to be pressed, which reduces the wear of the pen tip. At the same time, the top-down pressing is labor-saving and convenient. At the same time, the preset forces of the first spring 53 and the second spring 54 can control the ink output balance and improve the writing length of the valve pen.
