Description

refill gel pen

technical field

The invention belongs to a gel pen, in particular to a recyclable ink filling gel pen.

Background technique

In today's environment where gel pen writing is more and more widespread, whether it is signing, homework, accounting, writing official documents, etc., gel pens are basically used. Although the gel pen is very good for writing, the written words are not only beautiful, but also very convenient to carry, but it also has some disadvantages, that is, the service life is not long, and the ink of a gel pen is used up, and its service life It's over, and what's left is a plastic body that people can only throw away as garbage. This not only causes environmental pollution, but also increases the waste of resources. Especially for the earth, a planet with limited resources, human beings should use resources more rationally and save resources, so as to further promote the harmonious development of man and nature. Therefore, the design of recyclable automatic injection Ink gel pens not only conform to the historical trend, but also are a responsibility of human beings. Protecting the earth and saving resources are everyone's responsibility. After researching the design of most gel pens, we found that most gel pens are not suitable for refilling ink. If you pull out the nib to refill ordinary gel pens, it is inconvenient and affects the writing quality. For this reason, we designed a recyclable ink refill gel pen based on the mechanical principles we learned, which can effectively solve the problem. It can refill ink and write more conveniently, and feel the joy of innovation when you lightly press the ink refill with your hand.

Contents of the invention

The object of the present invention is to provide a recyclable gel ink pen, which fills ink in one direction through a one-way valve, the inside of the main pipe is sealed with a piston, and is isolated from atmospheric pressure, which is simple and practical, and realizes resource saving and environmental protection.

The present invention is achieved in this way, the recyclable gel ink pen, which includes a first one-way valve, a piston, a pen body, a nib connector, a nib, and the first one-way valve at the tail end of the pen is assembled inside the tail end of the pen body, The piston is placed in the main pipe of the pen body, the nib connector is mounted on the front end of the pen body, and the nib is tightly inserted into the nib connector.

The first one-way valve is connected with the secondary ink pipe in the pen body and the main pipe, and the secondary ink pipe and the main pipe are connected by a U-shaped pipe.

The ink injector includes a second one-way valve and an ink cartridge casing, and the second one-way valve is connected with the ink cartridge casing.

The present invention has the advantages that the purpose of circulating ink can be achieved by using a simple one-way valve principle, its structure is novel, simple in structure, easy to operate, it can effectively save the resources used in manufacturing gel pens and packaging gel pens, and Effectively reduce the plastic waste generated by the use of gel pens, protect the environment very well, and have good promotion value.

detailed description

The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

As shown in FIG. 1 , the recyclable gel ink pen includes a first one-way valve 1 , a piston 2 , a pen body 3 , a nib connector 4 , and a nib 5 . The first one-way valve 1 at the tail end of the pen is assembled inside the tail end of the pen body 3 and fastened with grooves to enhance stability. The piston 2 is placed in the main pipe 8 and can slide freely. The nib connector 4 is mounted on the front end of the pen body 3. When assembling, it should be as compact as possible so as not to fall off easily. The nib 5 is inserted into the nib connector 4 tightly. The first one-way valve 1 is connected with the ink secondary pipe 9 in the pen body 3 and the main pipe 8, and the ink secondary pipe 9 and the main pipe 8 are connected by a U-shaped pipe.

The ink injector includes a second one-way valve 6 and an ink cartridge housing 7 , and the second one-way valve is connected with the ink cartridge housing 7 .

The using method of the present invention is as follows: first the second one-way valve 6 of the ink injector is bumped against the first one-way valve 1 of the neutral pen (the two one-way valves have the same size), and they are extruded mutually to produce certain Gently squeeze the outer wall of the ink injector to make the ink inside the ink injector flow into the ink sub-pipe 9 (thin tube) of the gel pen along the gap, and the ink sub-pipe 9 and the main pipe 8 (thick tube) adopt U-shaped Tube connection, the ink flows into the main pipe from the secondary ink pipe 9, and pushes the piston 2 inside the main pipe to move upwards to complete the ink filling process. There is a small hole in the pipe wall above the piston 2, so that the air pressure above the piston 2 is always at atmospheric pressure. It is convenient for the pen to successfully complete the ink filling process and smoothly eject ink when writing. When writing, the piston 2 is lowered, and the nib 5 adopts a detachable assembly structure, and nibs of different sizes can be replaced according to the preferences of different people. Under the action of gently squeezing the ink injector with your hand, the ink in the ink injector enters the inside of the auxiliary pipe through the one-way valve, and the ink is replenished through the auxiliary pipe to the inside of the main pipe where the ink is consumed by writing. There is a small vent hole on the top of the main pipe , so that the top of the piston is always under an atmospheric pressure, the internal piston of the main pipe rises when ink is filled, and the piston descends when writing.
