Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the description of the embodiments, the terms "disposed," "connected," and the like are to be construed broadly unless otherwise explicitly specified or limited. For example, the connection can be fixed, detachable or integrated; can be mechanically or electrically connected; either directly or through an intervening medium, or through internal communication between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model discloses a novel pen without water receiver, as shown in fig. 1 to 4, including pen-holder 10, cap for brush 20, nib 30, tongue 40 and nib 50, nib 30's inside sets gradually nib 50 and tongue 40, and there is one in the pen-holder 10 inside cavity 11, has placed the package core 60 that has inhaled the ink in the cavity 11, and package core 60 has inserted a relay core 70 near one side of nib 30, and the one end detachably of nib 30 sets up in pen-holder 10, and in this embodiment, the screw thread that the outer wall set up is passed through to the one end of nib 30 closes with the internal thread that sets up in the pen-holder 10 soon and is connected.

The side of the pressure tongue 40 close to the roll core 60 is provided with an annular boss 41, the pressure tongue 40 is clamped in the pen tip 30 through the annular boss 41, the pressure tongue 40 can be pulled out from the pen tip 30 if necessary, one side of the pressure tongue 40 close to the roll core 60 is of a hollow structure, one side of the relay core 70 far away from the roll core 60 is inserted into the hollow structure of the pressure tongue 40, one side of the pressure tongue 40 close to the pen tip 30 is also provided with a through hole 42, and the hollow structure in the pressure tongue 40 is communicated with the pen tip 30 through the through hole 42.

In this structure, the ink bladder in the conventional ink bladder type pen is replaced with the ink-sucked core 60, and the ink in the core 60 is introduced into the tongue 40 and the pen tip 50 using the relay core 70, thereby enabling to secure normal writing. In addition, the relay core (equivalent to a water diversion core) can enable ink to be transferred to the pressure tongue 40 through the relay core on one hand, and can control the amount of the passed ink on the other hand, so that the phenomenon that a large amount of ink is gushed out to influence the uniformity of ink output and further influence the writing quality is avoided. When the ink amount in the roll core 60 is small and affects ink discharge, the roll core 60 may be used for ink absorption and then used continuously, or the remaining roll core 60 absorbed with ink may be replaced.

In the scheme, the low-price winding core 60 and the relay core 70 are used for replacing an ink absorber/ink bag and a high-price water storage device in the traditional fountain pen, so that the cost in the manufacturing process of the pen is greatly saved, and the production cost of an enterprise is reduced.

In order to further improve the uniformity and stability of ink discharge, the structure of the core wrap 60 and the relay core 70 is also designed in this document. Specifically, the porosity of the roll core 60 is 80% -90%, the porosity of the relay core 70 is 45% -55%, the roll core 60 comprises an external shell and a plurality of polyester filaments wrapped by the shell, the polyester filaments comprise straight filaments and bent filaments, and the number ratio of the straight filaments to the bent filaments is 1: (0.2-0.6), still include the nylon filament in the package core, the quantity ratio of dacron filament and nylon filament is 1: (0.08-0.25). Through the design of the structure of the winding core 60 and the relay core 70, the inventor practice proves that the pen in the structure has good ink discharging effect and stable and uniform ink discharging.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but must be based on the realization of those skilled in the art; when the technical solutions are contradictory or cannot be combined, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present invention.
