Detailed Implementation

[0032] The present invention will be further explained below with reference to specific implementation examples.

[0033] This invention solves the problem of frequent water changes in traditional brush-rinsing containers by installing multiple sets of small water-holding buckets 6 on both sides of the box body 1. When the water in one set of buckets 6 becomes dirty and unusable, the artist can easily remove the brush-rinsing component 7 from that set of buckets 6 and reinstall it on another set of buckets 6 containing clean water. This eliminates the need for frequent water changes during the painting process, avoiding the inconvenience caused by water contamination and saving time and effort.

[0034] By installing the water bucket 6 and the brush-rinsing component 7 on the box body 1, the painter no longer needs to carry a brush-rinsing bucket, reducing the burden of carrying it. Furthermore, when not in use, the brush-rinsing component 7 can be stored in the placement slot 21 of the box lid 2, not only ensuring proper storage of the brush-rinsing component 7 and preventing loss or damage, but also greatly reducing the space it occupies, making the entire watercolor box more compact and easy to store and carry.

[0035] By setting up the brush-rinsing component 7, the artist simply inserts the paintbrush under the fixed mounting cylinder 73 and then controls the brush-rinsing component 7 to begin the brush-rinsing operation via the control button on the protective shell 77. First, the controller 76 controls the longitudinal telescopic rod 71 to shorten, causing the brush tip to extend into the water tank 6, completing the initial brush tip immersion process. After the paintbrush has descended to the correct position, the controller 76 then controls the motor 78 to run, which drives the paintbrush to rotate via the fixed mounting cylinder 73. During this process, the brush tip rotates continuously within the water tank 6, thoroughly cleaning the paint from the brush tip. Compared to the traditional manual brush-rinsing method, this automated brush-rinsing operation is not only more effective and thoroughly removes paint stains from the brush tip, but also saves a significant amount of time and effort, greatly improving brush-rinsing efficiency. After brush rinsing is complete, the controller 76 controls the longitudinal telescopic rod 71 to extend, thereby causing the brush tip to rise. Once the paintbrush has risen to its designated position, the controller 76 controls the water control component 79 to effectively control the water level in the paintbrush tip, thereby preventing the tip from becoming too wet or too dry.

[0036] When the brush-rinsing assembly 7 needs to be installed, the artist simply inserts the outer rod 711 into the mounting hole 62 of the corresponding water container 6. Once the outer rod 711 is in place, the first magnet 621 and the second magnet 714 will automatically attract each other, thus firmly fixing the outer rod 711 inside the mounting hole 62 and ensuring the stability of the brush-rinsing assembly 7. This installation process is both simple and efficient, requiring minimal operation from the artist. When the water container 6 needs to be replaced, the artist simply pulls the outer rod 711 upwards to easily disconnect the attraction between the first magnet 621 and the second magnet 714, achieving quick disassembly and greatly improving operational convenience. Furthermore, the overall length extension and retraction of the longitudinal telescopic rod 71 is controlled by the telescopic end of the first electric push rod 713. The telescopic movement of the first electric push rod 713 determines the up-and-down sliding of the inner rod 712 relative to the outer rod 711. When the paintbrush needs to be lowered, the controller 76 will control the telescopic end of the electric push rod 713 to retract, thereby causing the inner rod 712 to slide downward relative to the outer rod 711, ensuring that the paintbrush accurately enters the water tank 6 for cleaning; when the paintbrush needs to be raised, the controller 76 will instruct the telescopic end of the electric push rod 713 to extend, thereby pushing the inner rod 712 to slide upward relative to the outer rod 711, so that the brush tip of the paintbrush leaves the water tank 6.

[0037] The funnel shape of the guide tube 732 effectively guides the upper end of the paintbrush. The artist doesn't need to spend excessive time aligning it; simply insert the upper end of the paintbrush easily into the guide tube 732, then gently push the paintbrush upwards. Guided by the funnel-shaped structure of the guide tube 732, the upper end of the paintbrush will automatically and smoothly slide into the mounting tube 73, accurately positioning itself in the correct place, thus ensuring successful installation of the paintbrush. This design not only improves operational efficiency but also reduces unnecessary time wastage.

[0038] The paintbrush is elastically secured using a flexible clamp 74. When the paintbrush is inserted into the mounting cylinder 73, when the upper end of the paintbrush contacts the locking block 742, the locking block 742 slides towards the fixing ring 741, compressing the spring 743. Simultaneously, the spring 743 applies an elastic force in the opposite direction, firmly clamping the paintbrush inside the mounting cylinder 73, ensuring it will not fall off or shift due to vibration or external force. Simultaneously, the elastic water control component 79 effectively controls the moisture content of the paintbrush tip. When the paintbrush reaches its designated position, the tip is positioned between the two sets of sponge blocks 791. At this point, the controller 76 extends the telescopic end of the electric push rod 796, causing the fixing block 792 and sponge blocks 791 to move towards the paintbrush tip. The sponge blocks 791 effectively control the moisture content of the brush tip as needed, preventing it from becoming too wet or too dry, ensuring smoothness and accuracy during the painting process. When the fixed block 792 moves, it drives the slider 794 to slide within the guide rail 795 via the L-shaped bracket 793. The guide rail 795 serves to limit and guide the slider 794, preventing the fixed block 792 from deviating during sliding. The clamping component 74 can be used to clamp paint pens of different diameters, thus broadening its applicability.

[0039] The water control component 79 effectively controls the moisture content of the paintbrush tip. When the paintbrush reaches its designated position, the tip is positioned between the two sets of sponge blocks 791. At this point, the controller 76 extends the telescopic end of the electric push rod 796, causing the fixed block 792 and sponge blocks 791 to move towards the paintbrush tip. The sponge blocks 791 effectively control the moisture content of the brush tip as needed, preventing it from becoming too wet or too dry, ensuring smoothness and accuracy during the painting process. As the fixed block 792 moves, it drives the slider 794 to slide within the guide rail 795 via the L-shaped bracket 793. The guide rail 795 limits and guides the slider 794, preventing the fixed block 792 from deviating during sliding.

[0040] The storage compartment 11 conceals a storage rack 5 for holding paintbrushes, allowing for neat storage while effectively saving space, enhancing the functionality of the watercolor box, and reducing the extra burden of carrying paintbrushes, making the entire painting process more convenient. Furthermore, during painting, the storage rack 5 can be easily pulled out to serve as a temporary place for paintbrushes. This design not only ensures that paintbrushes have a fixed and safe place but also prevents accidents caused by misplaced paintbrushes, such as paint smearing or staining the work area.

[0041] The above-described embodiments are merely illustrative of the implementation of this utility model, but should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
