Description

Technical Field

[0001] The invention relates to the technical field of stationery products, in particular to a calligraphy and painting pencil case. Background Art

[0002] With the development of the times, traditional calligraphy stationery has gradually shown its shortcomings in convenience, practicality and functionality. In particular, there are many problems that need to be solved in terms of ink storage, brush storage and moisturizing.

[0003] On the one hand, the storage and use of ink depend on a separate ink bottle, which not only increases the burden of carrying, but also easily causes pollution and waste if the ink bottle falls over or leaks during the writing process. At the same time, the container for holding ink (such as the inkstone) also needs to be equipped separately and cleaned in time after use, otherwise it is easy to leave ink stains, affecting the next use.

[0004] On the other hand, as the core tool for calligraphy creation, the storage and maintenance of the brush also face challenges. The traditional way to store brushes is often to place the entire brush in a pen holder or pen holder at random, lacking a special storage system to ensure the safety and moisturizing of the brush tip. The moisturizing of the brush tip for frequent writing is particularly critical. Frequent cleaning of the brush tip will cause unnecessary damage to the brush tip. If it is not cleaned in time or not cleaned thoroughly after use, the brush tip will become dry and hard and must be soaked again before use, which is time-consuming and laborious, and will also shorten the service life of the brush. Most of the moisturizing products on the market currently moisturize the entire brush, and it is difficult to achieve a separate sealed moisturizing of the brush tip, resulting in poor moisturizing effect.

[0005] In addition, the single function of calligraphy stationery is also a major drawback. Traditional calligraphy stationery often only has a single function of storing ink, holding ink or storing ink, which cannot meet the diverse needs of calligraphy enthusiasts, especially students, during the writing process. This not only increases the preparation time before writing, but also reduces the coherence and pleasure of writing. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to provide a calligraphy and painting pencil case.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0017] The button chamber is provided with one end open and fixedly connected to the housing. The button chamber is isolated from the ink cartridge or water cartridge. The button can perform a piston motion in the button chamber. The movement tracks of the button suction member and the button push-away magnet are always within the magnetic force influence range of the blocking magnet. When the button is pressed, the button suction member moves away from the blocking magnet, and at the same time, the button push-away magnet approaches the blocking magnet.

[0035] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of this embodiment, rather than all of the embodiments.

[0036] Refer to Figure 1 - Figure 10 , a painting and calligraphy stationery box, comprising:

[0037] The housing 1 encloses and divides the space of the painting and calligraphy stationery box into four chambers. The four chambers include an ink storage 11, an ink pool 12, a water storage 13, and a moisture storage 3; the four chambers form two mutually isolated systems, namely an ink system and a water system. The ink storage 11 is used to store ink, and the ink pool 12 is used to hold the ink injected from the ink storage 11; the liquid level of the ink storage 11 is not lower than the bottom plate of the ink pool 12 to ensure that the ink can flow from the ink storage 11 into the ink pool 12 by gravity.

[0038] The magnetic control valve 2 includes: a partition 21, a sealing plate 22, a button cavity 23, and a button 24; the partition 21 isolates the ink storage 11 and the ink pool 12 in the ink system from each other. The sealing plate 22 and the button cavity 23 are respectively arranged on both sides of the partition 21, and the button 24 is arranged in the button cavity 23; ink holes 211 are arranged on the partition 21; the magnetic control valve 2 uses the magnetic attraction of the magnetic component to make the sealing plate 22 press against the partition 21, and uses the magnetic repulsion of the magnetic component to push the sealing plate 22 away from the partition 21 to complete the blocking and opening of the ink holes 211, and control the flow of ink from the ink storage 11 to the ink pool 12.

[0039] The moisture storage 3 includes a moisture pad 31. The moisture storage 3 is an upper-opening container, and the moisture pad 31 is laid inside. The brush tip is placed against the moisture pad 31 for storage and moisture preservation; the water storage 13 provides water source for the moisture pad 31.

[0040] The brush barrel 4 is arranged in the housing 1 and is used to store the brush rod.

[0041] In an embodiment of the present invention, the ink storage chamber 11 is used to store ink. When it is necessary to inject ink into the ink pool 12, the user operates the magnetic control valve 2. Under the action of magnetic force, the ink hole 211 on the partition plate 21 is opened, and the ink flows from the ink storage chamber 11 through the ink hole 211 into the ink pool 12 under the action of gravity. A moisture preservation pad 31 is laid at the bottom of the moisture preservation chamber 3. The moisture preservation pad has a capillary action and can absorb and retain moisture. The upper end of the water suction pipe 32 is fixed to the bottom plate of the moisture preservation chamber 3, and the lower end extends deep into the water storage chamber 13. The moisture in the water storage chamber 13 is transported to the moisture preservation pad 31 through the water absorption rope 321 in the water suction pipe 32 by capillary action. The brush tip is stored in the moisture preservation chamber 3, and the bristles are in contact with the moisture preservation pad 31 to keep it in a moist state. The pen barrel 4 is used to store the brush pen barrel. The user can insert the brush pen barrel into the pen barrel 4 for fixing and taking out.

[0042] The magnetic control valve 2 enables the rapid and accurate flow of ink, avoiding the traditional operation of frequent manual pouring. Ink can be injected into the ink pool in small amounts multiple times, reducing ink waste. The separated design of the ink storage chamber 11 and the ink pool 12, as well as the ingenious setting of the magnetic control valve 2, achieve the efficient utilization and storage of ink. The moisture preservation chamber 3 enables the brush tip to always maintain a moist state. The capillary action of the moisture preservation pad 31 can continuously provide moisture for the brush tip, preventing the tip from being damaged due to drying and solidification caused by failure to clean in time or lack of cleaning conditions. It can temporarily moisturize the tip, eliminating the need for the user to frequently clean the tip in a short time interval and avoiding the damage caused by frequent cleaning. The setting of the pen barrel 4 makes it simple to store the brush pen barrel and convenient to retrieve. The scientific partition design of the multi-chambers of the housing 1, as well as the delicate structures of the magnetic control valve 2 and the pen barrel 4, lay the foundation for the innovation and practicality of the calligraphy and painting stationery box. This calligraphy and painting stationery box integrates multiple stationery items such as an ink bottle for storing ink, an ink cartridge for dipping ink, a moisture preservation box for moisturizing the tip, and a stationery box for storing the brush pen barrel, reflecting an innovative design concept. Its design fully considers the actual needs of calligraphy and painting enthusiasts and has high practicality and convenience.

[0043] As Figures 1 to 8 shown, in an embodiment of the present invention, the ink storage chamber 11 is a sealed cavity, and air holes 212 are also arranged on the partition plate 21; the air holes 212 connect the space above the ink surface in the ink storage chamber 11 with the outside air. When the air holes 212 are below the ink surface in the ink storage chamber 11, the air holes 212 are connected to a breathing tube that extends above the ink surface in the ink storage chamber 11.

[0044] In an embodiment of the present invention, the magnetic control valve 2 further includes: a shaft seat structural member 25 and a limiting member 26; the shaft seat structural member 25 and the limiting member 26 are fixedly connected to the wing plate extended from the partition plate 21; the wing plate can present different structural forms according to the different arrangement methods of the magnetic control valve 2 and the different structures of the shaft seat structural member 25 and the limiting member 26. In this embodiment, the magnetic control valve 2 is as Figures 1 to 3In the shown arrangement, the wing plate is connected and integrated with the top plate and the bottom plate of the housing 1; the magnetically controlled valve 2 can be arranged vertically or horizontally. The blocking plate 22 can be arranged on one side of the ink cartridge 11 as adopted in this embodiment, or the blocking plate 22 can be arranged on one side of the ink sump 12; the shaft seat structural member 25 is a structural member that enables the blocking plate 22 to rotate under its restraint. In addition to the circular hole shaft seat form adopted in this embodiment, as Figure 9 and Figure 10 shown in the other embodiments, the shaft seat structural member 25 can also exist in the form of a groove or a convex tooth, etc.; correspondingly, the rotating shaft structural member 222 is a structural member that can rotate in the shaft seat structural member 25. In addition to the circular shaft form adopted in this embodiment, as Figure 9 and Figure 10 shown in the other embodiments, one side edge of the blocking plate 22 can also be used as the rotating shaft structural member 222; the limiting member 26 is a structural member that restricts the movement range of the blocking plate 22. In addition to the cylinder adopted in this embodiment, as Figure 9 and Figure 10 shown in the other embodiments, the limiting member 26 can also be in the structural forms such as a beam or a plate.

[0045] In this embodiment, ink holes 211 and air holes 212 are arranged on the partition plate 21; a blocking magnet 221, a rotating shaft structural member 222, and a sealing member 223 are arranged on the blocking plate 22; a button attracting member 241 and a button pushing-away magnet 242 are arranged on the button 24.

[0046] In this embodiment, the blocking plate 22 is arranged on one side of the partition plate 21, the button cavity 23 is arranged on the other side of the partition plate 21, and the button 24 is arranged in the button cavity 23 and can perform a piston movement; normally, the blocking magnet 221 on the blocking plate 22 corresponds to the button attracting member 241 on the button 24. Through the magnetic attraction force between the blocking magnet 221 and the button attracting member 241, the blocking plate 22 is tightly pressed against the partition plate 21, and the sealing member 223 accurately blocks the ink holes 211 and the air holes 212, and the ink is sealed in the ink cartridge 11; when it is necessary to inject ink from the ink cartridge 11 into the ink sump 12, press the button 24, then the button attracting member 241 moves away from the blocking magnet 221, and at the same time the button pushing-away magnet 242 approaches the blocking magnet 221. The button pushing-away magnet 242 and the blocking magnet 221 magnetically repel each other, and the blocking plate 22 is rotated and pushed away from the partition plate 21, opening the ink holes 211 and the air holes 212, and the ink can flow from the ink cartridge 11 to the ink sump 12 for ink injection. After the ink injection process is completed, cancel the pressing force on the button 24, then the magnetic repulsive force between the button pushing-away magnet 242 and the blocking magnet 221 and the magnetic attractive force between the button attracting member 241 and the blocking magnet 221 act together on the button 24, causing the button 24 to automatically rebound and reset, and the ink cartridge 11 returns to the sealed state; the self-resetting function of the magnetically controlled valve 2 makes the magnetically controlled valve 2 simpler and more practical, improving the convenience and efficiency of use.

[0047] When the ink tank 11 is a closed chamber, pouring ink from the ink tank 11 into the ink pool 12 will reduce the atmospheric pressure in the space above the ink liquid surface. Opening the air hole 212 can maintain the air pressure balance inside and outside the ink tank 11.

[0048] During the pressing and resetting process of the button 24, the movement trajectory of the button attraction member 241 and the button push magnet 242 is always within the magnetic influence range of the blocking magnet 221. Under this premise, the angle between the movement trajectory of the button 24 and the blocking plate 22 can be arbitrary. Figure 4 and Figure 9 As shown, the angle between the movement trajectory of the button 24 and the blocking plate 22 differs by 90 degrees between the two schemes; the rotation and tilting direction of the blocking plate 22 can also be multi-directional, which depends on the arrangement direction of the shaft structure 222 and the shaft seat structure 25. Different arrangements produce different stress states of the structural parts, which should be determined according to the specific situation.

[0049] The design of the cylindrical rotating shaft and the round hole shaft seat adopted in this embodiment ensures that the sealing plug 223 can be more accurately aligned with the ink hole 211 and the air hole 212 each time it is closed, and the rotation of the sealing plate 22 is also smoother.

[0050] In this embodiment, the rotating shaft structure 222 and the sealing magnet 221 on the sealing plate 22 are disposed on both sides of the ink hole 211 and the air hole 212. The advantage of this arrangement is that a relatively large pressure of the sealing member 223 on the ink hole 211 and the air hole 212 is obtained with a relatively small magnetic attraction force, which can seal the ink tank 11 more stably and tightly and better prevent ink leakage.

[0051] In the embodiment of the present invention, the sealing member 223 is made of silicone material, and the installation method is to make a hole in the blocking plate 22, and the sealing member 223 is fixed through the hole. The silicone sealing member 223 has good elasticity, flexibility and durability, and can very well implement stable and long-term sealing of the ink hole 211 and the air hole 212. In other embodiments, the sealing member 223 may also be made of other types of rubber, plastic, metal and other materials.

[0052] Since the button 24 needs to be clearly pressed and travel a certain distance to open the ink hole 211 and the air hole 212, ink leakage caused by accidental contact or misoperation is effectively prevented, and the fault tolerance effect is excellent. The magnetic control valve 2 uses the design of magnetic adsorption and magnetic repulsion to reduce the risk of mechanical wear and damage, which can effectively improve the overall durability and service life of the calligraphy and painting pencil case.

[0053] In an embodiment of the present invention, the air hole 212 directly connects the space above the ink surface of the ink cartridge 11 with the outside air; in another embodiment, when the air hole 212 is below the ink surface of the ink cartridge 11, a breathing tube can be installed at the air hole 212 to connect the space above the ink surface of the ink cartridge 11 with the outside air.

[0054] As Figures 1 to 2 shown, in an embodiment of the present invention, when replenishing the ink in the ink cartridge 11, ink is poured into the ink cartridge 11 from the ink filling port 111 provided in the moisture preservation chamber 3. After the ink pouring is completed, the ink filling port 111 needs to be sealed with a sealing plug or a sealing cover.

[0055] In this embodiment, the ink filling port 111 is provided in the moisture preservation chamber 3, making the appearance of the painting and calligraphy stationery box more concise and beautiful. The ink filling port 111 is provided on a locally raised step. After the ink is filled, there is enough space above the ink surface of the ink cartridge 11, so that the air hole 212 can always be exposed above the ink surface. The design of the locally raised step also keeps the ink filling port 111 clean and prevents the ink stain on the moisture preservation pad 31 from contaminating the hands of the operator.

[0056] As Figures 1 to 2 shown, in an embodiment of the present invention, when replenishing water in the water reservoir 13, water is added to the water reservoir 13 from the water filling port 131 provided in the moisture preservation chamber 3. After the water addition is completed, the water filling port 131 needs to be sealed with a sealing plug or a sealing cover.

[0057] In this embodiment, the water filling port 131 is arranged on a locally raised step in the moisture preservation chamber 3. The design of the locally raised step can keep the inlet of the water filling port 131 clean and prevent the ink stain on the moisture preservation pad 31 from contaminating the water filling port and further contaminating the hands of the operator.

[0058] In an embodiment of the present invention, as Figure 1 、 Figure 2 shown, the moisture preservation chamber 3 further includes a water suction pipe 32, a water absorption rope 321 and a pen tip fixing member 33. The pen tip fixing member 33 is arranged on the housing 1 in the moisture preservation chamber 3. The pen tip to be stored is magnetically adsorbed on the pen tip fixing member 33 by the magnetic structure at the end of the pen tip; the upper end of the water suction pipe 32 is fixedly connected to the bottom of the moisture preservation chamber 3, and the lower end of the water suction pipe 32 extends deep into the water reservoir 13; the water absorption rope 321 is filled in the water suction pipe 32. The water absorption rope 321 has a capillary structure, one end is connected to the moisture preservation pad 31, and the other end extends deep into the water reservoir 13. Under the capillary action, water is lifted and transported along the water absorption rope 321 to the moisture preservation pad 31 to achieve automatic water absorption and moisture preservation; at the same time, the water absorption rope 321 can also block the direct leakage of water from the water suction pipe 32 when the painting and calligraphy stationery box is overturned, enabling the moisture preservation box 3 to absorb water and moisturize without spilling or leaking water, providing conditions for the portability of the painting and calligraphy stationery box.

[0059] If the writing brush is to be used again in a short time after being dipped in ink, the brush head does not need to be cleaned. Separate the brush head from the brush handle, and directly put the inked brush head into the moisture preservation chamber 3 for moisture preservation. The brush hair part is placed against the moisture preservation pad 31 to keep the brush head moist and prevent it from drying out and hardening. At any time, take out the brush head and magnetically connect it to the brush handle to directly write, saving the trouble of frequent brush washing, solving the problems of difficult brush washing and inconvenient carrying due to limited environmental conditions, and providing great convenience for users of writing brushes, especially students.

[0060] The brush head fixing part 33 magnetically fixes the brush head, and the brush head can stably lean against the moisture preservation pad 31, and will not fall off or move due to the shaking or overturning of the painting and calligraphy stationery box, eliminating the risk of ink stain and brush hair damage caused by the shaking or falling off of the brush head.

[0061] In an embodiment of the present invention, the pen barrel 4 includes a pen barrel fixing part 41; the pen barrel 4 is a cylindrical shape with one end open, the open end is connected to the housing 1, and is isolated from the ink storage chamber 11 and the water storage chamber 13.

[0062] The pen barrel fixing part 41 is fixedly installed at the end of the pen barrel 4 far away from the open end; the pen barrel fixing part 41 is magnetically attracted to the structural part at the end of the pen barrel, and the pen barrel is magnetically fixed in the pen barrel 4.

[0063] In this embodiment, the end of the pen barrel adopts a magnetic structural part with no less than two magnetic poles and opposite directions of adjacent magnetic poles. At the same time, the pen barrel fixing part 41 is fixed and installed at an eccentric position at the end of the pen barrel 4 by a magnet. When the pen barrel is inserted into the pen barrel 4, the magnetic structural part at the end of the pen barrel will automatically rotate the angle so that one of the magnetic poles in the magnetic structural part at the end of the pen barrel corresponds to the position of the pen barrel fixing part 41 and is magnetically attracted, magnetically fixing the pen barrel, thus eliminating the trouble of manually finding the position and angle; twist the pen barrel at the open end of the pen barrel 4, and another adjacent magnetic pole in the magnetic structural part at the end of the pen barrel approaches the pen barrel fixing part 41 and generates a magnetic repulsive force, pushing the pen barrel out of the pen barrel 4; using the principle that the tangential force of two magnets is much smaller than the axial force, only a very small force is needed to rotate the pen barrel.

[0064] In another embodiment, the pen barrel fixing part 41 can be made of soft magnetic material, and the magnetic structural part at the end of the pen barrel is magnetically attracted to the pen barrel fixing part 41. When taking the pen barrel, the pen barrel can only be axially pulled out and cannot be taken out by rotating the pen barrel.

[0065] In order to keep the moisture preservation chamber 3 and the ink pool 12 moist for a long time and prevent water loss and drying, a cover plate 5 is provided on the top of the moisture preservation chamber 3 and the ink pool 12.

[0066] In the present invention, the "ink" and "ink juice" mentioned can also be replaced with other liquids. For example, replacing "ink" with "water", then this painting and calligraphy stationery box can be used for outdoor sketching of watercolor paintings or writing practice on a water writing cloth.

[0067] It should be specifically noted that the "magnet" in the text refers to a permanent magnet, the "magnetic structural member" refers to a structural member with a permanent magnet, and the "soft magnetic material" refers to a material with low coercivity and high magnetic permeability, such as pure iron.

[0068] The "button engaging member 241", the "pen tip fixing member 33", and the "pen barrel fixing member 41" can all be magnetic structural members or structural members made of soft magnetic materials; among a pair of structural members that are mutually attracted and magnetically fixed, at least one party is a magnet or a magnetic structural member.

[0069] As described above, it is only the preferred specific implementation manner of this embodiment, but the protection scope of this embodiment is not limited thereto. Any person skilled in the art within the technical scope disclosed by this embodiment, according to the technical solution and inventive concept of this embodiment, makes equivalent replacements or changes, and all should be covered within the protection scope of this embodiment.
