Description

Technical Field

[0001] This invention relates to a paintbrush, and more particularly to an oil painting brush having a liquid pigment storage tube and a brush tip. Background Technology

[0002] Announcement No. CN213082757U discloses an oil painting line pen. This pen has a ballpoint pen tip made of copper or stainless steel, with a ball at the end of the tip that fits precisely with its base. Therefore, due to its material and structural characteristics, the pen tip is not easily modifiable by the user. To obtain a pen tip with a ball diameter other than those available on the market (e.g., 2.1, 5.0 mm), it must be custom-made. Each custom-made tip requires approximately 4000-5000 RMB in mold fees and related material costs, making the process complex and expensive. While there are marker pens on the market consisting of a liquid paint reservoir, a pen tip, and liquid paint, there are no marker pens that use liquid oil paint mixed with linseed oil in the reservoir, have a microporous pen tip, and are designed for oil painting. Summary of the Invention

[0003] The purpose of this invention is to provide a marker for oil painting, comprising a liquid paint reservoir, liquid oil paint, and a brush tip. Compared to the prior art document "CN213082757U An Oil Painting Line Pen," the brush tip of this pen can be modified from commercially available brush tips into different shapes and sizes to meet the needs of drawing different images. The modification method is simple and free. The liquid paint reservoir stores the liquid oil paint supplied to the brush tip. The liquid paint reservoir can be straight or curved. The straight liquid paint reservoir is suitable for painting on a flat surface, while the curved liquid paint reservoir is suitable for painting on an upright surface. This design allows the brush tip to maintain an angle of approximately 90 degrees relative to the surface for easy painting, while also ensuring the liquid paint reservoir is upright, facilitating the smooth flow of liquid oil paint from top to bottom. The paint ultimately permeates through the micropores of the brush tip to the end, fulfilling the needs of the painting. The liquid paint storage tube is made of plastic, with an outer diameter of 5-10 mm, an aperture of 3.5-8 mm, and a length of 150-200 mm. The curvature of the bent portion of the liquid paint storage tube is 90-130 degrees. The bending method involves inserting a spring, slightly smaller than the aperture diameter and approximately the length of the bent portion, into the aperture of the plastic tube. The bent portion of the plastic tube is then uniformly heated and bent to the desired curvature. After cooling and setting, the spring is removed. One end of the liquid paint storage tube is connected to the brush tip via an insertion joint. The aperture of the liquid paint storage tube used for inserting the brush tip is 0.1 mm smaller than the diameter of the insertion portion of the brush tip to ensure a secure connection. The insertion depth is one-third of the brush tip length. The brush tip of this invention has a microporous structure, which serves as a penetration channel for the liquid oil paint. The size and density of the micropores, along with the viscosity of the liquid oil paint, control and adjust the amount and speed of liquid oil paint seepage from the brush tip. The pen tip of this invention belongs to the category of marker pen tips. Pen tips are classified into two types based on their material: one is a fiber pen tip, made of fiber, resin, and adhesive; the other is a plastic pen tip, made of foamed plastic. Painting oil paintings is a highly personalized artistic activity, encompassing the artist's personal pursuits, individual expressive forms, and personal artistic style. Commercially available marker pen tips with microporous structures, primarily used for writing rather than professional painting, cannot meet the personalized needs of oil painting in terms of shape and size. Therefore, modifying the pen tip is necessary.Due to the material and structural features of the pen tip of this invention, commercially available pen tips can be modified from large to small to meet the needs of drawing different images. The modification method involves using abrasive tools such as grinding wheels or sandpaper, or cutting tools such as knives or scissors, or a combination of both, to create the required shape and size of pen tips to satisfy the needs of representing different images. For example, the lower end of a commercially available 10mm diameter, 29.5mm long round pen tip can be cut into a semi-circular sheet shape with a thickness transitioning from 1mm on one side to 3mm on the other. Oil painting markers made with such a pen tip can draw lines that gradually transition from 1mm to 3mm in width vertically, and lines that are solid in the middle and blurred at the edges horizontally, meeting the needs of depicting such images. The liquid paint storage tube is filled with liquid oil paint, which is made by diluting commercially available paste oil paint with linseed oil, which is used as a thinner for the oil paint. The fluidity and permeability of liquid oil paint are adjusted by varying the mixing ratio of paste oil paint and linseed oil to control the consistency, bleeding rate, and amount of liquid paint seeping from the brush tip. A higher proportion of linseed oil results in higher fluidity and permeability of the liquid oil paint, leading to lower consistency, faster bleeding, and a larger amount of paint seeping from the brush tip; conversely, a lower proportion of linseed oil results in lower fluidity and permeability, leading to higher consistency, slower bleeding, and a smaller amount of paint seeping from the brush tip. The viscosity, fluidity, and permeability of the liquid oil paint are determined by the needs of the image being painted. Liquid oil paint requiring higher viscosity and a thicker coating will have lower fluidity and permeability; conversely, liquid oil paint requiring lower viscosity and a thinner coating will have better fluidity and permeability. The viscosity, fluidity, and permeability of the liquid oil paint are determined by allowing it to smoothly permeate through the micropores of the brush tip to the end of the brush tip. The liquid oil paint of this invention is dispensed into a liquid paint storage tube using an injection syringe.When painting with oil paint, the tip of a straight liquid paint reservoir in an oil paint marker and the liquid paint reservoir are held upright at approximately a 90-degree angle to the flat canvas. For an oil paint marker with a curved liquid paint reservoir, one end of the curved tip is aligned with the upright canvas at approximately a 90-degree angle, while the other end is approximately parallel to the upright canvas. Due to gravity and the fluidity and permeability of the liquid oil paint in the reservoir, the liquid oil paint flows downwards to the tip, permeating through the micropores to the end of the tip, saturating it with liquid oil paint. The liquid oil paint is then transferred to the canvas through contact with the paint-covered tip or by stroking the canvas, thus fulfilling the basic coloring function of an oil paint marker and enabling the creation of an oil painting. An oil painting refers to a painting made with oil paint. Given that linseed oil is a drying oil and the brush tip has micropores, to prevent the linseed oil from hardening and clogging the micropores, the liquid oil paint in the liquid paint storage tube is suitable for immediate preparation and filling, and should be cleaned with a paintbrush cleaner such as turpentine after use. Because the brush tip of this invention is made of microporous fiber or plastic, its material and structure allow users to easily and inexpensively modify it themselves using simple methods such as cutting and sanding to obtain brush tips of different sizes and shapes to meet the needs of drawing different images. Compared with the brush tip of an oil painting line brush with publication number CN213082757U, users can obtain brush tips of different sizes and shapes from those on the market through self-modification; the modification method is simple and free.

[0008] Example 1. A plastic tube 150 mm long, 7.4 mm outer diameter, and 6.0 mm inner diameter is used as the liquid pigment storage tube 1 of this invention. The lower half of a foamed plastic microporous pen tip 2 with a diameter of not less than 6.1 mm and a length of not less than 30 mm is cut into a flat shape with a knife. The width of the flat part of the pen tip 2 is 6.1 mm, the thickness is 2.0 mm, and the bottom edge is a 30-degree bevel. The upper half of the pen tip 2 is cylindrical with a diameter of 6.1 mm and a length of 30 mm. The upper end of the pen tip 2 is inserted into one end of the liquid pigment storage tube 1 to a depth of 10 mm. Liquid oil paint 3 diluted with linseed oil is injected into the other end of the liquid pigment storage tube 1 using an injection syringe to make an oil painting marker. Because the tip of this pen has a flat, beveled shape, it can draw lines of three widths: one is the width of the pen tip, one is the thickness of the pen tip, and the other is the sharp angle of the bevel of the pen tip, to meet the needs of representing images of these three sizes.

[0009] Example 2. A plastic tube 150 mm long, 5.0 mm outer diameter, and 2.9 mm inner diameter is used as the liquid pigment storage tube 1 of this invention. The lower end of a microporous fiber brush tip 2 with a diameter of not less than 3.0 mm and a length of not less than 20 mm is ground with a grinding wheel into a straight shape with a cross-sectional thickness of 1 mm and a width of 3 mm. The straight shape is then cut into a serrated shape with a cutting tool. The upper end of the brush tip 2 is cylindrical with a diameter of 3.0 mm and a length of 20 mm. The upper end of the brush tip 2 is inserted into one end of the liquid pigment storage tube 1 to a depth of 7 mm. Liquid oil paint 3 diluted with linseed oil is injected into the other end of the liquid pigment storage tube 1 using a syringe to make an oil painting marker. The serrated end of this brush tip is used to represent equidistant linear images.
