Description

Knitting wool pen, drawing board matched with knitting wool pen and stationery or toy containing knitting wool pen

Technical Field

The invention relates to the field of stationery and toys, in particular to the field of art stationery and toys for children, and more particularly relates to a knitting wool pen, a drawing board matched with the knitting wool pen and stationery or toys containing the knitting wool pen.

Background

The common painting toys in the market at present are mainly of a plurality of types, namely, painting is carried out on paper or various materials by using the traditional pens made of various materials, such as crayons on paper surfaces and chalks on blackboard surfaces; the other is to draw on a special drawing board by using magnetic materials and the like; other types are: scraping the preprinted coating to reveal the pattern; and drawing toys made by utilizing the principle that liquid crystals develop color after being pressed.

Knitting wool, also called knitting wool, is a common textile, and can be spun from various natural or artificial materials such as wool, cashmere, camel hair, rabbit hair, yak hair, acrylic fiber, polyester fiber, boston fiber and the like. Therefore, the knitting wool can present different color levels and textures. Meanwhile, the woolen yarn has rich colors, and as the woolen yarn is spun by a plurality of yarns, different color elements can be added to form richer color effects, such as mixed yarn, space dyeing yarn and the like. The yarn spun from different materials or the yarn for different applications has different naming modes, such as knitting yarn, cotton yarn, hemp yarn, silk yarn, sewing thread, etc., and all of them have fluff or ring-shaped structures on their surfaces, which are collectively called knitting yarn herein.

The painting made of the knitting wool has a strong color effect, and compared with the traditional painting mode, the painting made of the knitting wool has a good stereoscopic impression and hand feeling, and can provide richer painting experience and display diversified aesthetic features. For example, CN1184738A discloses a pile splicing and sticking picture handicraft, which is formed by drawing down the knitting wool into piles, and then splicing and sticking the piles with different colors on the patterns according to the patterns drawn by the worker on the base plate. The method is complex to operate, auxiliary products such as glue are needed, the method is not suitable for low-age children, and the method is different from the drawing in the true sense, so that the method is a piece of work in a collage mode.

The pen is the most popular writing tool for human beings, and generally comprises a pen holder, wherein a hole is formed in one writing end of the pen holder, and a pen point of a pen core penetrates through the hole and leaks outside the pen holder, so that a writing function is realized. After writing is completed, the pen is lifted, and the pen point is separated from the paper medium, namely, the writing is stopped.

However, when the knitting wool is used as a writing instrument and combined with a pen, many problems occur. Such as how the knitting wool passes through the pen holder and leaks out of the hole at the front end of the pen holder.

For adults, a solution to this problem may be to use a "threading" technique, where the term "threading" is used to refer to threading a wire through a completely closed, unopened hole. For example: threading the sewing thread through the thread hole of the needle; the knitting wool passes through the tubular hollow pen holder. However, even for adults, the difficulty of threading the knitting wool out of the pen shaft without using tools such as a threader is great. This approach is essentially impractical for young children (children around 3 years). If the tools such as threading devices (usually made of metal filaments, metal sheets, etc.) are used, the tools themselves have sharp points, edges, or the tools themselves are small articles, so that the tools have high use risks and are easy to injure children.

Meanwhile, after writing is completed, how to separate the knitting wool on the work from the knitting wool at the pen point, which can be possible for adults by means of scissors, blades and other tools; however, for children, such tools are at considerable risk, and special attention is paid to or even forbidden in the safety standards of toys in various countries, such as national standard GB6675 "safety standards for toys", and the use of tools should be avoided as much as possible. Meanwhile, the user experience of the toy is certainly reduced by means of the tool, because the user always needs to carry some other tools instead of only carrying the knitting wool pen toy, the user experience is reduced, and the risk of losing is increased; from the viewpoint of cost, the method is uneconomical and not environment-friendly.
