Description

Moisturizing device for preventing ink from evaporating at slit of pen point

Technical Field

The invention relates to a pen, in particular to a moisturizing device for preventing ink at a slit of a pen point from evaporating.

Background

As is known, a pen generally comprises a cap, a nib, a tongue, a holding position, a shaft and an inking system, and the writing principle of the pen is as follows: the water-based ink in the penholder is led into the penholder tongue under the action of gravity, and then the ink is continuously led out under the capillary action of the pen nib to keep writing; wherein, the principle that capillary phenomenon takes place is: the liquid is arranged at the inner side of the thin tubular object and is formed by combining the adhesive force between the liquid and the object and the surface tension generated by the cohesive force, so that the liquid flows to the thin tubular object under the condition of not applying external force; its initiation requires two conditions, namely: the object is made of hydrophilic materials and liquid exists in the slit, and the pen cannot write normally when any link of the object is in a problem. When the pen is not used for a long time, ink at the pen point of the pen is continuously evaporated until the ink is completely evaporated, no ink exists in the narrow slit of the pen point at the moment, and the capillary phenomenon cannot be continuous, so that the ink cannot smoothly flow down, namely, the phenomenon that the pen is dry is generated.

Aiming at the problem of dry pen, the technical personnel in the field propose different solutions, the cavity volume is reduced by changing the shape design of a pen cap so as to reduce the evaporation of the ink at the pen point most commonly, hero and park pens change the traditional cylindrical pen cap into a shuttle-shaped pen cap, Japanese Bai le Ka Li imperial concubine pen adopts a rotary threaded pen cap, German 'Ling Mei' pen adopts a double-layer pen cap design, the cavities of the pen caps are reduced, the exchange of moist air in the pen cap and the outside air is further reduced, and the evaporation of the ink at the pen point is finally reduced; although the technology can solve the problem of dry and astringent pen point to a certain extent, the situation that the pen cannot be written smoothly still occurs after being placed for one week; although the German 'Lingmei' pen further improves the ink control technology and controls the ink output according to the writing weight, the situation that writing cannot be performed also occurs after the pen cap is covered and the pen is placed for 2 weeks, and due to the technical cost, the pens with the function in the above pen manufacturers are expensive, and the used technology cannot be widely popularized and applied to the design of other pens. Therefore, it is a basic demand of those skilled in the art to provide a moisturizing device that can be widely used and prevents evaporation of ink from the slit of the pen tip.

Detailed Description

The present invention will be explained in detail by the following examples, which are disclosed for the purpose of protecting all technical improvements within the scope of the present invention.

The moisturizing device for preventing ink evaporation at the slit of the pen point, which is described in the attached figure 1, comprises a pen cap 6, wherein the rear end of the pen cap 6 is connected with a pen body 7, the pen cap 6 is arranged outside the front end of the pen body 7, and the rear end of the pen cap 6 is connected with the middle part of the pen body 7 in a plugging or threaded manner; the pen cap 6 is cylindrical with openings at two ends; the front end of the pen cap 6 is provided with a neck-reducing opening 5, an annular upper cap body 2 is fixedly connected to the neck-reducing opening 5, the neck-reducing opening 5 is sleeved with the upper cap body 2 or fixedly connected through threads, a transparent cover 1 is fixed to the top surface of the upper cap body 2, an inner circle surface at the front end of the upper cap body 2 is provided with a step extending inwards, and the edge of the transparent cover 1 is bonded to the step; go up the internal humidity paper 3 and the material 4 of moisturizing that is equipped with of cap body 2, humidity paper 3 sets up between transparent cover 1 and the material 4 of moisturizing, and the diameter of the material 4 of moisturizing is greater than the internal diameter of necking down 5, and the nib of pen body 7 and the material 4 of moisturizing contactless, and the material 4 of moisturizing is sponge, cotton or cotton fiber, and thickness is 2-4mm, and the outer disc of the material 4 of moisturizing contacts with the interior disc of last cap body 2.

When the moisturizing device for preventing ink evaporation at the slit of the pen nib is implemented, the moisturizing material 4 is fully wetted to be suitable for preventing water from dripping, the moisturizing material 4 is arranged in the upper cap body 2, the upper cap body 2 is communicated with the pen cap 6, the pen nib of the pen body 7 is not in contact with the moisturizing material 4, and due to the fact that moisture is contained in the moisturizing material, if the moisturizing material is connected with the pen nib, water in the moisturizing material is exchanged with ink in the pen nib, ink marks in the pen nib are lightened after the exchange, and the moisturizing material 4 is polluted; the color change condition of the humidity paper 3 is observed through the transparent cover 1 to inject water into the moisturizing material 4, and the water injection mode can be realized by dripping water into the pen cap 6 or separating the upper cap body 2 from the pen cap 6 and then injecting water for moistening; the invention is also suitable for pens with not tight seal and larger cavity volume in the pen cap, the wet air in the pen cap 6 is slightly circulated with the outside in the long-term idle process of the pen, the method can still keep the air humidity in the pen cap 6 at the saturated vapor pressure level, and the ordinary pen with simple process and low price can also thoroughly get rid of the problem of dry and astringent pen point.

The humidity paper is called as a humidity card, is an existing product and is low in manufacturing cost; the humidity paper is made by utilizing the principle that cobalt chloride (Co (H20)4Cl 2) or other chemical materials can change color after absorbing water; the cobalt chloride is blue when dried, and the chemical composition is [ Co (H20)4Cl2 ]; the color turns red after absorbing moisture, and the chemical composition becomes [ Co (H2O)6]2 +; the humidity card compares the color development condition under different humidity with the color comparison card, so that the humidity value can be known, and the moisture preserving material 4 is not required to be filled with water for judgment.

In order to verify the feasibility of the patent, a group of simple experiments are designed to simply verify the method, and the experiments adopt a cheap pen in a common store, a pen with a Nippon Baile imperial concubine screw cap and a pen with a German Lingmei double-layer cap design and an optimized ink supply system as experimental objects; the experimental results shown in the attached figure 2 show that the placing time of the pen without dry pen is short for the ordinary pen, the pen with the threaded cap and the pen with the optimized ink supply system, and the placing time of the pen which can still normally write can be obviously prolonged by using the invention, so that the practicability of the pen is greatly improved, and the service performance of the pen is improved.

The present invention is not described in detail in the prior art.

The embodiments selected for the purpose of disclosing the invention, are presently considered to be suitable, it being understood, however, that the invention is intended to cover all variations and modifications of the embodiments which fall within the spirit and scope of the invention.
