Abstract

The invention discloses a direct liquid type pen, which comprises a pen holder, wherein an ink bin positioned at the rear end and a pen head cavity positioned at the front end are arranged in the pen holder; the follow-up plug is arranged in the pen holder to separate the pen head cavity from the ink bin; the guide pipe penetrates through the follow-up plug from the pen head cavity and extends to the ink chamber, and a water guide core is arranged in the guide pipe and guides the ink to the pen head through capillary force; the direct-liquid pen does not adopt the traditional ink storage device or a mode of adjusting ink by a valve and ink absorption cotton, but dynamically changes the volume of the ink bin by the displacement of the follow-up plug, and simultaneously the follow-up plug keeps sealing the ink bin, thereby changing the mode of adjusting ink by the traditional direct-liquid pen in principle and solving the problems of inconvenient use and ink leakage caused by more and more air in the ink bin along with the consumption of ink.

Description

Direct-liquid type pen

Technical Field

The invention relates to stationery, in particular to a direct liquid type pen.

Background

The existing direct liquid type pen is a writing pen filled with liquid ink, the most representative of the pen is two types, the first type is products with types of ARP50801 and ARP50802 produced by Shanghai Chenguang Stationery corporation, the pen is filled with water-based ink, because the viscosity of the ink is much lower than that of the ink of a common gel pen, writing is smooth and smooth, and market approval is obtained more and more in recent years, the pen uses a water storage device (also called a regulator) formed by injecting hard plastic, the outer circumference of the water storage device is provided with an ink storage ring groove, the air pressure balance between the ink and the air in an ink bin and the outside is regulated by the water storage device, the air in the ink bin is above the ink liquid level when a pen point faces downwards, when the air pressure of the ink bin is higher than the outside air pressure due to environmental change (for example, the air pressure in the ink bin is higher than the outside air pressure due to the rise of the environmental temperature), part of the ink is extruded by the air in the ink bin, so as to leave the ink storage device and enter the water storage device, along with the continuous consumption of ink in the writing process, the air in the ink bin is also continuously increased, when the volume of the ink bin is larger, if the volume of the extruded ink exceeds the ink storage capacity (the adjusting capacity of an adjuster) of the water receiver, the excessive ink can overflow out of the pen holder or the pen point to cause ink leakage, the quality control requirement of the pen on the water receiver is high, the ink leakage is easily caused due to poor quality, the production efficiency is low, and the production cost is high; the second type is a direct liquid type white board pen manufactured by force group limited company with model number S518, which adopts a valve and an ink absorption cotton to adjust ink, partial ink enters the ink absorption cotton from an ink bin after the valve is opened, the valve is closed in the writing process, ink in the ink absorption cotton is not smooth after being consumed, the valve needs to be opened again, so that inconvenience in use is caused, air in the ink bin is more and more consumed along with the continuous consumption of the ink, the air pressure in the ink bin is increased when the ambient temperature is increased, and a large amount of ink overflows under the action of the air pressure in the ink bin to cause ink leakage when the valve is opened.

Disclosure of Invention

The invention provides a direct-liquid pen, which can solve the technical problems of ink leakage and inconvenience in use of the conventional direct-liquid pen, and is realized by adopting the following technical scheme:

a direct liquid type pen, comprising:

the pen holder is internally provided with an ink bin positioned at the rear end, a pen point cavity positioned at the front end and a follow-up plug positioned between the ink bin and the pen point cavity;

the follow-up plug can move along the long axis direction of the pen holder along with the change of the ink volume in the ink bin and keep the sealing state of the ink bin, and the pen holder can be provided with an ink filling port at the rear end thereof for more convenient ink filling so as to be communicated with the ink bin and provided with a tail plug for sealing the ink filling port after ink filling;

a conduit extending from the nib chamber through the follower plug into the ink chamber, the conduit having an opening disposed within the ink chamber;

the water guide core is arranged in the conduit, continuous tiny gaps are formed in the water guide core, the water guide core has capillary attraction to ink, the water guide core can be formed by plastic raw materials through extrusion molding or by bundling fine fibers, and the water guide core and the conduit can be separated or directly integrated;

the nib, its one end is located the nib intracavity, and one end extends to the outside in nib chamber in addition, when adopting fibre nib or extrusion molding's micropore nib the nib with the diversion core can also integrated into one piece by split type, for example use the whiteboard pen, marker and the fluorescence pen of fibre nib.

Furthermore, the follow-up plug is composed of a follow-up plug support and a lubricating sealant, the follow-up plug support mainly plays a role in supporting the lubricating sealant, and the specific structure and size of the follow-up plug can be designed according to actual conditions.

Further, the main components of the lubricating sealing agent are lithium-based ester and silicone oil.

Furthermore, an air return channel is arranged in the pen holder and communicates the pen point cavity with the air outside the pen holder.

Further, the conduit extends to the rear end of the ink chamber.

The following plug is also correspondingly and gradually displaced to the rear end of the pen holder along the long axis of the pen holder under the action of external air pressure of the pen holder along with continuous consumption of ink in the writing process of the pen, the volume of the ink bin is correspondingly reduced, meanwhile, the following plug keeps the seal of the ink bin, and air outside the ink bin cannot enter the ink bin.

The direct liquid type pen can adopt a proper ink filling mode or a centrifugal process to discharge most or all of the air in the ink bin in the production process.

The existing direct-liquid type pen can consume more and more air in the ink cabin along with the ink in the writing process, when the ambient temperature rises or the ambient air pressure becomes small, the ink in the ink cabin can overflow the ink cabin under the action of the internal air pressure, and can overflow the pen holder to cause ink leakage in serious cases.

Compared with the prior art, the invention has the advantages and positive effects that: the invention designs the follow-up plug to separate the ink bin at the rear end of the penholder from the pen point cavity at the front end of the penholder, thereby thoroughly changing the ink adjusting structure of the existing direct-liquid pen in principle, eliminating the phenomenon that the air in the ink bin is more and more consumed along with the ink of the existing direct-liquid pen, solving the ink leakage phenomenon caused by the influence of environmental change on the air pressure in the ink bin, avoiding the need of arranging a traditional water storage device or a valve and ink absorption cotton to adjust the ink, being suitable for the common writing pens filled with liquid ink, comprising ball-point pens, fluorescent pens, white board pens and marking pens, and having low production cost and easy quality control.
