Description

Technical Field

[0001] The utility model relates to the technical field of marker pens, in particular to a double-headed marker pen with low ink residue. Background Art

[0002] Marker pens are widely used in writing and painting due to their rich colors, brush stroke effects and ease of use. In order to meet the needs of wider use, the types of resins, pigments and effect agents of inks are becoming increasingly rich. The ink of traditional marker pens is mainly in the form of flowing liquid or the ink is stored in the pen holder in a non-flowing form through an ink absorber. However, storing it in the form of flowing liquid is prone to ink explosion, and when storing it in a non-flowing form through an ink absorber, when faced with inks with poor fluidity and easily stratified effect agents, there are problems such as poor ink supply continuity.

[0003] In addition, in the prior art, the ink is stored in the pen holder in a non-flowing form through an ink absorbing body. When the ink of the marker pen is exhausted (the pen tip turns white when writing), 10% to 30% of the ink remains in the ink absorbing body (cotton core), resulting in serious waste of ink.

[0004] Therefore, there is an urgent need to design a double-headed marker pen with low ink residue, which has the function of double-head writing, can prevent ink explosion, has good ink supply continuity, and can better adapt to inks with different characteristics and components.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0029] like Figure 1 As shown, a double-headed marker pen with low ink residue comprises a pen body 10 and a pen tip 20. The pen body 10 is a container-like structure with openings at both ends and an ink storage cavity 11 disposed therein. The ink storage cavity 11 is used to store liquid ink. Ink control components are disposed at the openings at both ends of the pen body 10 respectively.

[0030] The ink control assembly includes a pen tip 30 which is a hollow through structure. An ink guide rod 50 connected to the ink storage chamber 11 is disposed at one end of the pen tip 30, and a pen tip 20 is disposed at the other end. An ink absorber 40 for absorbing liquid ink is disposed between the pen tip 20 and the ink guide rod 50.

[0031] The ink guide rod 50 includes a main body 51 sleeved with the pen tip 30, and an ink control hole 52 is arranged inside the main body 51 to make the ink storage cavity 11 and the ink absorbing body 40 communicate with each other in an airtight manner;

[0032] The ink absorbing body 40 is a structure with dense pores, and the ink control hole 52 and the pen tip 20 are in contact with the ink absorbing body 40 respectively.

[0033] In this embodiment, the liquid ink tank is first installed in the ink storage cavity 11, and then the ink control assembly is installed. The liquid ink is transferred from the ink control hole 52 to the ink absorbing body 40 under the action of gravity and capillary effect. The ink is affected by the surface tension in the ink control hole 52. The flow rate of the ink can be combined with the surface tension of the ink to design the size of the ink control hole 52 to control the fluidity of the ink. After the liquid ink enters the ink absorbing body 40, the ink is affected by the surface tension in the dense pores, and the ink becomes immobile. The ink conduction between the pen tip 20 and the ink absorbing body 40 is transferred by the capillary effect.

[0034] In actual practice, depending on factors such as the composition, fluidity and surface tension of the ink, the ink absorber 40 can obtain a dense porous structure by compressing a fiber mass, or it can obtain a dense porous structure by sintering a metal or non-metal powder, such as copper, ceramic, polyethylene and other materials.

[0035] The porosity of the ink absorber 40 can be adaptively adjusted according to the ink characteristics.

[0036] This embodiment stores and supplies ink in a combination of fluid and non-fluid, and has the advantages of large ink storage capacity of direct liquid markers and stable ink discharge and no ink explosion of cotton core markers. Moreover, when the marker pen is used until the nib turns white, the ink residue inside is less than 8%, while the ink residue of ordinary cotton core markers is usually between 10% and 30%. The use of the utility model to store and supply ink can reduce ink residue and reduce waste.

[0037] Furthermore, two ink storage chambers 11 are provided, and the two ink storage chambers 11 are respectively connected to different pen tips 20 through ink control components.

[0038] In this embodiment, inks of different colors or characteristics can be stored in the two ink storage chambers 11 respectively, so as to achieve a multi-color effect of one stroke.

[0039] Furthermore, in order to improve the capillary conduction effect of the ink, the ink absorbing body 40 is a flexible fiber body with dense pores, and the ink control hole 52 and the pen tip 20 are respectively inserted into the interior of the ink absorbing body 40. The fiber can be natural fiber or chemical fiber, such as cotton, polyester fiber, etc.

[0040] Furthermore, according to the composition, fluidity and surface tension of commonly used inks, in order to ensure smooth ink supply and prevent ink explosion and obtain a good ink supply effect, the ink control hole 52 is a cylindrical hole with a diameter of 0.2 to 3 mm.

[0041] Furthermore, in order to obtain an ideal ink storage capacity and ink control effect, the ratio of the volume of the ink absorbing body 40 to the volume of the ink storage cavity 11 is less than or equal to 25%.

[0042] Furthermore, in order to prevent the ink from stratifying after long-term storage and affecting the ink painting effect, an ink distribution block 60 is provided in the ink storage cavity 11, and the density of the ink distribution block 60 is greater than the density of the ink.

[0043] When in use, the marker pen is shaken to make the ink block 60 shake in the ink, so that the ink components are evenly distributed, especially for inks with easily stratified effect agents such as glitter powder, which can significantly avoid the problem of inconsistent calligraphy and painting effects.

[0044] Furthermore, the ink distribution block 60 is made of stainless steel or ceramic material, and has a spherical or columnar shape.

[0045] Furthermore, in order to prevent the ink storage chamber 11 from supplying ink unsmoothly due to the pressure difference between the inside and outside, a ventilation groove 31 is provided between the pen tip 20 and the pen mouth 30 to connect the ink absorber 40 with the outside in an airtight manner.

[0046] Furthermore, in order to maintain the structural stability of the flexible fiber body and reduce the contact between the ink and the pen tip, the ink absorbing body 40 is a cylindrical structure, and a plastic film is arranged on the outer side of the cylindrical surface of the cylinder.

[0047] Furthermore, in order to prevent the pen tip from being accidentally damaged, a pen cap 70 covering the pen tip 20 is provided on the outer side of the pen tip 20 , and the pen cap 70 is detachably connected to the pen mouth 30 or the pen body 10 .

[0048] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
