Abstract

Adopt the technology of the monochromatic coloured art pen of existing manufacturing, produce a kind of colour changeable pen of any color that can draw.Utilize three primary colors can mix the principle of all colors,, make three pen cores, nibs lean on very closely and do not contact mutually synthetic one of red, yellow, blue three kinds of primary color set.Students in middle and primary schools' fine arts lessons, geography class, drawing, charting are used.Reading, production will be made the shades of colour sign on books and product.

Description

Colour changeable pen

The present invention relates to a kind of writing implement that can variable color.

A pen will possess the function of conversion color, for example three kinds of colors of conversion, and existing method is to adorn three heterochromatic pen cores in penholder, the mechanicalness device is set again to drive pen core, nib to implement its colour change function.But, because of following this method,, for example be increased to four, five kind if will increase the color kind again, then pen core, nib and mechanism thereof also will be set up thereupon, and this is for not being difficult to implement the too thick penholder.Secondly, drive pen core with mechanism, require pen core to have certain rigidity, so writing implement for the softish pen core, as coloured art pen, marking pen etc., because pen core adopts the synthon liquid storage,, will have very big difficulty with mechanism conversion pen core, nib.

The objective of the invention is to provide a kind of color changing method and above-mentioned different writing implement, it not only can make the coloured art pen of the range expansion of colour changeable pen to flexible pen core, marking pen etc., and make the kind of variable color be increased to seven kinds to eight kinds.

Invention is achieved in that the nib of several different colors concentrated and is installed on the nib, make between the nib mutually near and do not contact mutually, and the receiving all color liquid that communicates with described nib and mutually not the pen core of mixed flow also be to be contained in regularly among the penholder.Write when writing not and the vertical custom of paper in view of people.Because last several the nibs of this nib do not contact mutually, therefore, the pitch angle of writing can make every nib all can write out separately color separately.

Further improvement of the present invention is that above-mentioned pen core of all kinds is chosen as three kinds of primary colors liquid, becomes red pen core.Yellow pen core and blue pen core.Because though last several the nibs of above-mentioned nib do not contact mutually, but lean on very closely, can access the principle of various colors according to three primary colors in the chromatology, this pen is in the process that is coated with, draws, three primary colors, in pairs can be from mixing three kinds of secondary colors, (green, orange, purple), even and then can be mixed into the colourful coffee color of tone, secondary color again such as black-and-blue.So, this be one can become seven, the pen of eight kind of color.

Advantage of the present invention is, because without mechanism, so simple in structure, it is easy, with low cost to implement; Simultaneously, only need rotating penholder slightly during owing to variable color, do not end just energy variable color of writing process, variable color is convenient, rapid; In addition, because the starting point of the present invention does not lie in a kind of color and must establish a pen core, the allomeric function of three primary colors be combined into can mark seven kinds of colors at least, this has exceeded each several part function sum, make trichromatic mixing change procedure on a pen, show to such an extent that specifically understand therefrom, so this can become the audiovisual aids of the concocting method of pupil's art course teaching color.In addition,, be stranded this because the function of a pen can substitute the monochromatic pen of racemosus, middle school student's map making no matter, people make reading note with heterochromatic difference, can feel easy to carry because of only using one.

The concrete structure of invention is by providing with next embodiment and accompanying drawing.

Fig. 1 is the sectional view of a kind of colour changeable pen of proposition according to the present invention.

Describe the details and the situation of the coloured art pen that proposes according to the present invention in detail below in conjunction with Fig. 1.

This pen comprises penholder (2), pen plug (1), pen core (5), nib (6) and nib (7).Three not connected ducts (3) are arranged in the penholder (2), and its cross section is three 120 ° fan-shaped (4).A kind of natural colored pen core (5) respectively is housed in each duct.Respectively be connected with a nib (6) under three primary colors pen cores, three nibs are concentrated and are installed on the nib (7), make between nib adjacent to each other and do not contact (8) mutually.The pen of penholder upper end is plugged with three statures, respectively clogs a penholder duct, makes that three kinds of primary colors neither flow out penholder in three pen cores, also mixed flow mutually.

Penholder can be used the transparent plastics injection moulding.See through penholder like this and see chromatic pen core, both convenient the use, it is attractive in appearance that pen is rich in.
