Description

Technical Field

[0001] This utility model relates to drawing tools, specifically to a fun electronic colored pen kit. Background Technology

[0002] Currently, with social progress and improved living conditions, more and more children are participating in painting. Drawing helps develop children's interests, improves their intelligence, enhances their hands-on skills, strengthens interaction and communication between children and parents, and fosters a closer relationship between children and elders. However, children are naturally active and mischievous, often running and jumping around while painting, and frequently scribbling on walls, furniture, and even clothes, causing some trouble for parents and teachers. Therefore, it is necessary to invent a fun watercolor pen that can only produce color on matching paper.

[0003] For example, the invention patent with publication number "CN111559192A" entitled "A Children's Fun Watercolor Pen and Matching Paper" discloses a children's fun watercolor pen and matching paper, including matching paper and watercolor pens. The matching paper contains color-developing microcapsules, each containing several non-reactive color-changing color-developing agents. The microcapsules are separated from the base paper by starch, and the surface of the color-developing layer is sealed by a protective layer, ensuring the stability of the microcapsules during daily storage and handling. The color-developing agent inside the watercolor pen is a colorless and transparent liquid, which only develops color upon contact with the colorant in the microcapsules. While this avoids scribbling and soiling walls, furniture, and other non-painting areas, the colorless colorant is directly inside the watercolor pen. Therefore, multiple pens are needed, which not only takes up a lot of space and is inconvenient to store and carry, but also makes it difficult to quickly find the desired pen among many colors while drawing, and also easily leads to lost pens. Summary of the Invention

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a fun electronic colored pencil kit with a reasonable structural design that facilitates drawing.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A fun electronic colored pencil kit includes a pencil body, a paint tray, a color-producing lamp assembly, a magnetic component, a functional circuit board, and a magnetic field sensing device. The functional circuit board is located inside the paint tray, which has several ink cartridges. A corresponding magnetic field sensing device is located inside the paint tray for each ink cartridge. Each magnetic field sensing device is connected to the functional circuit board. The magnetic component is located at the tip of the pencil body, and the color-producing lamp assembly is located on the pencil body and connected to the functional circuit board via wires.

[0007] As a preferred embodiment of this utility model, the pen tip is provided with soft bristles, which have a better ink absorption effect and a softer and smoother feel when moving on the paper, providing users with a better writing or drawing experience.

[0008] As a preferred embodiment of this utility model, the color-rendering lamp group includes a light panel and LEDs disposed on the light panel for emitting light of the corresponding color.

[0010] As a preferred embodiment of this utility model, the paint tray is provided with a placement position that matches the shape of the pen body. When not in use, the pen body can be conveniently placed on the paint tray, which not only avoids the loss of the pen body, but also makes the whole kit neater, more orderly, and convenient for storage and carrying.

[0011] As a preferred embodiment of this utility model, the material box is provided with a material cover that can close its opening, preventing the ink inside the material box from evaporating and becoming contaminated.

[0012] In a preferred embodiment of this invention, the ink box contains colorless ink. This prevents scribbling and drawing from soiling non-painting areas such as walls and furniture.

[0013] As a preferred embodiment of this utility model, the pigment tray is equipped with a power supply connected to the functional circuit board, thereby improving the convenience of use.

[0014] As a preferred embodiment of this utility model, it also includes a tray cover, which covers the pigment tray and covers all the paint boxes, making the entire kit neater and more aesthetically pleasing.

[0015] The beneficial effects of this utility model are as follows: The structure is rationally designed. Each ink cartridge holds a colorless ink of the corresponding color. When the pen tip dips into the ink cartridge of the desired target color, the magnetic field sensor at the corresponding cartridge position senses the magnetic field of the magnetic component at the pen tip and sends feedback to the functional circuit board. The functional circuit board controls the color-rendering lamp assembly to emit light corresponding to the desired target color, allowing the user to quickly know the current color of the pen. This results in a better drawing experience, increasing the fun of drawing and making the pen look more aesthetically pleasing. Furthermore, color selection is flexible and convenient, eliminating the need to carry multiple colored pens. It occupies little space, making it easy to carry and store. The pen is connected via a wire, preventing loss and ensuring convenient use anytime. Additionally, the use of colorless ink ensures color development only on compatible paper, satisfying children's drawing needs while preventing scribbling in non-drawing areas.

[0020] Figure 4 This is an exploded structural diagram of the pigment palette in this utility model. Detailed Implementation

[0021] See the example. Figures 1 to 4 This embodiment provides a fun electronic colored pencil kit, which includes a pencil body 1, a paint tray 2, a color-producing lamp group 3, a magnetic component 4, a functional circuit board 5, a magnetic field sensing device 6, a paint cover 7, a tray cover 8, and a power supply 9. In this embodiment, the magnetic component 4 is preferably a permanent magnet, and the magnetic field sensing device 6 is preferably a Hall sensor.

[0022] The functional circuit board 5 is located inside the paint tray 2. The paint tray 2 has several ink cartridges 21, each with a lid 7 that closes its opening to prevent ink evaporation and contamination. The tray lid 8 covers the paint tray 2 and conceals all the ink cartridges 21, making the entire kit neater and more aesthetically pleasing. Each ink cartridge 21 holds a type of colorless ink. The colorless ink is a colorless and transparent developing liquid that only displays its color when applied to compatible paper, satisfying children's drawing needs while preventing scribbling in non-drawing areas.

[0023] For each material box 21, a corresponding magnetic field sensing device 6 is provided in the pigment tray 2, and each magnetic field sensing device 6 is connected to the functional circuit board 5.

[0024] The magnetic component 4 is located at the tip of the pen body 1. In this way, when the pen tip of the pen body 1 is dipped into the ink cartridge 21 of the desired target color, the magnetic field sensing device 6 at the corresponding position of the ink cartridge 21 can sense the magnetic field of the magnetic component 4 at the pen tip position.

[0025] The color-rendering lamp group 3 is mounted on the pen body 1 and connected to the functional circuit board 5 via wires 10. The color-rendering lamp group 3 includes a light panel 31 and LEDs 32 mounted on the light panel 31, used to emit light of the corresponding color. The pen body 1 can be entirely translucent or only partially translucent, as long as the light from the LEDs 32 can be transmitted.

[0026] Preferably, the pen tip of the pen body 1 is provided with soft bristles 11, which have a better ink absorption effect and a softer, smoother feel when moving on paper, providing the user with a better writing or drawing experience. In other embodiments, the pen tip of the pen body 1 may also be provided with a fiber tip or a sponge tip.

[0027] Preferably, the paint tray 2 is provided with a placement position 22 that is adapted to the shape of the pen body 1. When not in use, the pen body 1 can be positioned and placed in the placement position 22 by means of magnetic attraction or claws, which not only avoids the loss of the pen body 1, but also makes the whole kit neater, more orderly, and convenient for storage and carrying.

[0028] In this embodiment, the power source 9 is a battery compartment located on the bottom surface of the pigment tray 2, used to hold three AA batteries. In other embodiments, the power source 9 can also be a rechargeable lithium battery, built into the pigment tray 2.

[0029] In use, colorless inks of different colors are placed in each ink box 21. For example, the first position is red, and the ink box contains colorless ink that will turn red after painting; the second position is green, and the ink box contains colorless ink that will turn green after painting; the third position is yellow, and the ink box contains colorless ink that will turn yellow after painting, and so on. The positions of the aforementioned colors have been pre-programmed on the functional circuit board 5.

[0030] When painting, if green is needed, the tip of the pen body 1 is dipped into the ink cartridge at the second position. The magnetic field sensor 6 at the bottom of the ink cartridge at the second position senses the magnetic field of the magnetic component 4 at the pen tip and sends feedback to the functional circuit board 5. The functional circuit board 5 then determines that the tip of the pen body 1 has been dipped into the ink cartridge at the second position and controls the color rendering lamp group 3 to emit green light, allowing the user to quickly know that the ink dipped in the pen body 1 is green. When other colors are needed, the tip of the pen body 1 is simply dipped into the corresponding ink cartridge, eliminating the need to carry multiple colored pens and bringing convenience to painting.
