Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to a calligraphy and painting stationery box. Background Technology

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

[0003] On the one hand, the storage and use of ink rely on separate ink bottles, which not only increases the burden of carrying them, but also easily causes pollution and waste if the ink bottle is tipped over or leaks during writing. At the same time, the container for holding ink (such as an inkstone) also needs to be provided separately and cleaned in time after use, otherwise ink stains will easily remain and affect 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. Traditional brush storage methods often involve simply placing the entire brush haphazardly in a brush holder or rack, lacking a dedicated storage system to ensure the safety and moisture retention of the brush tip. Moisturizing the brush tip, which is frequently used, is particularly crucial. Frequent washing of the brush tip can cause unnecessary damage. If it is not cleaned promptly or thoroughly after use, the brush tip will dry out and harden, requiring it to be soaked again before use, which is time-consuming, laborious, and shortens the brush's lifespan. Currently, most moisturizing products on the market are designed to moisturize the entire brush, making it difficult to achieve individual, sealed moisturization of the brush tip, resulting in poor moisturizing effects.

[0005] Furthermore, the limited functionality of calligraphy stationery is a major drawback. Traditional calligraphy stationery often only has the function of storing, holding, or organizing ink, failing to meet the diverse needs of calligraphy enthusiasts, especially students, during the writing process. This not only increases preparation time before writing but also reduces the fluency and enjoyment of writing. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a calligraphy and painting stationery box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A calligraphy and painting stationery box, comprising:

[0009] The shell divides the space of the calligraphy and painting stationery box into four chambers, including an ink tank, an inkwell, a water tank, and a humidification chamber; the ink tank is used to store ink, and the inkwell is an open container used to hold the ink injected from the ink tank;

[0010] A magnetic control valve includes: a partition, a sealing plate, a button cavity, and a button; the partition isolates the ink tank and the ink reservoir from each other; the sealing plate and the button cavity are located on opposite sides of the partition; the button is located within the button cavity; ink holes are arranged on the partition; the magnetic control valve uses magnetic attraction to press the sealing plate against the partition to seal the ink holes, and uses magnetic repulsion to push the sealing plate away from the partition to open the ink holes, thereby controlling the flow of ink from the ink tank to the ink reservoir;

[0011] A moisturizing compartment includes a moisturizing pad. The moisturizing compartment is an open-top container with the moisturizing pad placed inside. The brush tip is placed against the moisturizing pad for storage and moisturization. The water tank provides water to the moisturizing pad.

[0012] A pen holder, located inside the casing, is used to store the pen handle;

[0013] Preferably, when the ink tank is a sealed cavity, the partition is also provided with air holes; the air holes connect the space above the ink surface of the ink tank with the outside air, and when the air holes are below the ink surface of the ink tank, the air holes are connected to a vent pipe extending to the ink surface of the ink tank.

[0014] Preferably, the magnetic control valve further includes a shaft seat structure and a limiting member; the shaft seat structure and the limiting member are fixedly connected to the wing plate extending from the partition; the sealing plate includes a rotating shaft structure and a sealing member, the rotating shaft structure and the sealing member being fixedly arranged on the sealing plate; the rotating shaft structure is installed in the shaft seat structure, and the sealing plate can rotate around the rotating shaft structure between the partition and the limiting member. The sealing member corresponds to the position of the ink orifice; when the ink tank is a sealed cavity, the sealing member also corresponds to the position of the air orifice.

[0015] Preferably, the button includes a button engaging component and a button pushing magnet, the button engaging component and the button pushing magnet being fixedly arranged on the button; the sealing plate includes a sealing magnet, the sealing magnet being fixedly arranged on the sealing plate;

[0016] When the button engaging component corresponds to the sealing magnet, they magnetically engage with each other, and the sealing component seals the ink pores; when the ink tank is a sealed cavity, the sealing component also seals the air pores.

[0017] The button cavity is open at one end and fixedly connected to the housing. The button cavity is isolated from the ink tank or water tank. The button can move like a piston in the button cavity. The movement trajectory of the button engaging component and the button pushing away magnet is always within the magnetic influence range of the sealing magnet. When the button is pressed, the button engaging component moves away from the sealing magnet, while the button pushing away magnet moves closer to the sealing magnet. The button pushing away magnet and the sealing magnet repel each other magnetically, causing the sealing plate to rotate and push away from the partition to open the ink hole. When the ink tank is a sealed cavity, the air hole is opened at the same time.

[0018] Preferably, the ink tank is provided with an ink filling port, and when the ink tank is replenished with ink, ink is poured into the ink tank through the ink filling port.

[0019] Preferably, the water tank is provided with a water inlet, and when the water tank is replenished, water is poured into the water tank through the water inlet.

[0020] Preferably, the moisturizing chamber further includes a water-absorbing tube, a water-absorbing rope, and a pen tip fixing component. The pen tip fixing component is disposed on the shell inside the moisturizing chamber. The stored pen tip is attracted to the pen tip fixing component by a magnetic structure at the end of the pen tip, and the bristles of the pen tip are attached to the moisturizing pad. The upper end of the water-absorbing tube is fixedly connected to the bottom of the moisturizing chamber, and the lower end of the water-absorbing tube extends into the depth of the water chamber. The water-absorbing tube is filled with a water-absorbing rope, which has a capillary structure. One end of the water-absorbing rope is connected to the moisturizing pad, and the other end extends into the depth of the water chamber. Water is absorbed and transported to the moisturizing pad by the capillary action of the water-absorbing rope.

[0021] Preferably, the pen barrel includes a pen barrel fixing component. The pen barrel is a cylindrical structure with one end sealed, and the open end is fixedly connected to the housing for storing the brush handle. The pen barrel fixing component is installed at the sealed end of the pen barrel. The pen barrel fixing component is magnetically attracted to the structural component at the end of the pen handle, thus magnetically fixing the pen handle in the pen barrel.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] This utility model integrates multiple functions such as ink storage, ink holding, pen tip storage and moisturizing, and pen barrel storage.

[0035] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments.

[0036] Reference Figure 1 - Figure 10 A type of calligraphy and painting stationery box, comprising:

[0037] The outer shell 1 divides the space of the calligraphy and painting stationery box into four chambers, including an ink tank 11, an ink pool 12, a water tank 13, and a humidification chamber 3. The four chambers form two mutually isolated systems, namely an ink system and a water system. The ink tank 11 is used to store ink, and the ink pool 12 is used to hold the ink injected by the ink tank 11. The liquid level in the ink tank 11 is not lower than the bottom plate of the ink pool 12, ensuring that the ink can flow from the ink tank 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 tank 11 and the ink pool 12 in the ink system from each other, the sealing plate 22 and the button cavity 23 are placed on both sides of the partition 21, and the button 24 is placed in the button cavity 23; ink holes 211 are arranged on the partition 21; the magnetic control valve 2 uses the magnetic attraction force of the magnetic component to press the sealing plate 22 against the partition 21, and uses the magnetic repulsion force of the magnetic component to push the sealing plate 22 away from the partition 21, thereby completing the sealing and opening of the ink holes 211 and controlling the flow of ink from the ink tank 11 to the ink pool 12.

[0039] The moisturizing compartment 3 includes a moisturizing pad 31. The moisturizing compartment 3 is an open container with a moisturizing pad 31 inside. The brush tip is placed against the moisturizing pad 31 for storage and moisturization. The water compartment 13 provides water to the moisturizing pad 31.

[0040] The pen holder 4 is located inside the housing 1 and is used to store the pen holder.

[0041] In this embodiment of the invention, the ink tank 11 is used to store ink. When ink needs to be injected into the ink reservoir 12, the user operates the magnetic control valve 2, using magnetic force to open the ink hole 211 on the partition 21. Under the action of gravity, the ink flows from the ink tank 11 through the ink hole 211 into the ink reservoir 12. A moisturizing pad 31 is laid at the bottom of the moisturizing tank 3. This moisturizing pad has 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 moisturizing tank 3, and the lower end extends into the depth of the water tank 13. The water suction rope 321 in the water suction pipe 32 uses capillary action to transport the water in the water tank 13 to the moisturizing pad 31. The brush head is stored in the moisturizing tank 3, and the brush bristles are attached to the moisturizing pad 31 to keep them moist. The brush barrel 4 is used to store the brush barrel. The user can insert the brush barrel into the brush barrel 4 to fix it and take it out.

[0042] The magnetic control valve 2 enables rapid and accurate ink flow, avoiding the need for frequent manual refilling. It allows for multiple small infusions of ink into the inkwell, reducing waste. The separate design of the ink tank 11 and inkwell 12, along with the ingenious design of the magnetic control valve 2, achieves efficient ink utilization and storage. The moisturizing chamber 3 keeps the brush tip constantly moist. The capillary action of the moisturizing pad 31 continuously provides moisture to the brush tip, preventing damage caused by dryness and hardening due to lack of timely or suitable cleaning. It provides temporary moisturization, eliminating the need for frequent brush tip cleaning and avoiding damage from frequent washing. The brush barrel 4 allows for simple storage and quick, convenient access to the brush. The scientifically designed multi-cavity structure of the shell 1, along with the ingenious construction of the magnetic control valve 2 and the brush barrel 4, establishes the innovation and practicality of this calligraphy and painting stationery box. This calligraphy and painting pencil case integrates multiple stationery items into one unit, including an ink bottle for storing ink, an ink cartridge for dipping ink, a moisturizing box for keeping brush tips moist, and a pencil case for storing brush handles, reflecting an innovative design concept. Its design fully considers the practical needs of calligraphy and painting enthusiasts, offering high practicality and convenience.

[0043] like Figures 1 to 8 As shown in the embodiment of this utility model, the ink tank 11 is a sealed cavity, and the partition 21 is also provided with air holes 212; the air holes 212 connect the space above the ink surface of the ink tank 11 with the outside air, and when the air holes 212 are below the ink surface of the ink tank 11, the air holes 212 are connected to the vent pipe extending to the ink surface of the ink tank 11.

[0044] In this embodiment of the present invention, the magnetic valve 2 further includes: a shaft seat structure 25 and a limiting member 26; the shaft seat structure 25 and the limiting member 26 are fixedly connected to the wing plate extending from the partition 21; the wing plate can present different structural forms depending on the arrangement of the magnetic valve 2 and the different constructions of the shaft seat structure 25 and the limiting member 26. In this embodiment, the magnetic valve 2 is as follows: Figures 1 to 3 As shown in the arrangement, the wing plate is connected and fused with the top and bottom plates of the housing 1; the magnetic valve 2 can be arranged vertically or horizontally, and can be positioned on one side of the ink tank 11 as in this embodiment, or on one side of the ink pool 12; the bearing structure 25 is a structure that allows the bearing plate 22 to rotate under its constraint, and besides the round hole bearing form used in this embodiment, such as... Figure 9 and Figure 10 In another embodiment shown, the bearing seat structure 25 can also be in the form of a groove or a tooth; correspondingly, the rotating shaft structure 222 is a structure that can rotate within the bearing seat structure 25, and besides the round shaft form used in this embodiment, it can also be... Figure 9 and Figure 10 In another embodiment shown, one side of the sealing plate 22 can also be used as a pivot structure 222; the limiting member 26 is a structural member that restricts the range of motion of the sealing plate 22, and in addition to the cylinder used in this embodiment, such as Figure 9 and Figure 10 In another embodiment shown, the limiting member 26 can also be a beam, plate, or other structural form.

[0045] In this embodiment, the partition 21 is provided with ink holes 211 and air holes 212; the sealing plate 22 is provided with sealing magnets 221, rotating shaft structure 222, and sealing element 223; the button 24 is provided with button engaging element 241 and button pushing away magnet 242.

[0046] In this embodiment, the sealing plate 22 is arranged on one side of the partition 21, the button cavity 23 is arranged on the other side of the partition 21, and the button 24 is disposed in the button cavity 23 and can perform piston movement. Under normal conditions, the sealing magnet 221 on the sealing plate 22 corresponds to the button engaging member 241 on the button 24. Through the magnetic attraction between the sealing magnet 221 and the button engaging member 241, the sealing plate 22 is pressed tightly against the partition 21, and the sealing member 223 accurately seals the ink hole 211. The ink is sealed in the ink tank 11 through the vent 212. When ink needs to be injected from the ink tank 11 into the ink reservoir 12, pressing button 24 causes button engagement 241 to move away from the sealing magnet 221, while button push-away magnet 242 moves closer to the sealing magnet 221. The button push-away magnet 242 and the sealing magnet 221 magnetically repel each other, causing the sealing plate 22 to rotate and push away from the partition 21, opening the ink vent 211 and the vent 212, allowing ink to flow from the ink tank 11 into the ink reservoir 12. After the ink injection process is completed, releasing the pressure on button 24 causes the magnetic repulsion between the button push-away magnet 242 and the sealing magnet 221, along with the magnetic attraction between the button engagement 241 and the sealing magnet 221, to act on button 24, causing it to automatically spring back and reset, returning the ink tank 11 to a sealed state. The self-resetting function of the magnetic control valve 2 makes it simpler and more practical, improving ease of use and efficiency.

[0047] When the ink tank 11 is a closed chamber, the space above the ink surface will become larger and the atmospheric pressure will decrease when ink is injected from the ink tank 11 to the ink pool 12. 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 button 24, the movement trajectory of button engaging component 241 and button pushing away magnet 242 is always within the magnetic influence range of sealing magnet 221. Under this premise, the angle between the movement trajectory of button 24 and sealing plate 22 can be arbitrary. Figure 4 and Figure 9 As shown, the angle between the movement trajectory of button 24 and the sealing plate 22 differs by 90 degrees between the two schemes; the rotation and tilting direction of the sealing plate 22 can also be multi-directional, depending on the arrangement direction of the rotating shaft structure 222 and the bearing structure 25. Different arrangements result in different stress states of the structural components, which should be determined according to the specific situation.

[0049] The cylindrical rotating shaft and circular hole bearing design used 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 respectively placed 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 element 223 on the ink hole 211 and the air hole 212 can be obtained with a relatively small magnetic attraction force, which can more stably and tightly seal the ink tank 11 and improve the ink leakage prevention effect.

[0051] In this embodiment of the invention, the sealing element 223 is made of silicone material. The installation method involves drilling holes in the sealing plate 22, through which the sealing element 223 is fixed. The silicone sealing element 223 possesses good elasticity, flexibility, and durability, enabling it to provide a stable and long-lasting seal for the ink pores 211 and air pores 212. In other embodiments, the sealing element 223 may also be made of other types of rubber, as well as plastics, metals, and other materials.

[0052] Because button 24 requires a firm press and a certain travel distance to open ink orifice 211 and air orifice 212, it effectively prevents ink leakage caused by accidental touches or misoperations, exhibiting excellent fault tolerance. The magnetic control valve 2 utilizes a design of magnetic adsorption and magnetic repulsion, reducing the risk of mechanical wear and damage, and effectively improving the overall durability and lifespan of the stationery box.

[0053] In one embodiment of the present invention, the vent 212 directly connects the space above the ink surface of the ink tank 11 with the outside air; in another embodiment, when the vent 212 is below the ink surface of the ink tank 11, the vent 212 can be fitted with a vent pipe to connect the space above the ink surface of the ink tank 11 with the outside air.

[0054] like Figures 1 to 2 As shown in the embodiment of this utility model, when the ink tank 11 is replenished with ink, ink is poured into the ink tank 11 through the ink filling port 111 provided in the humidification chamber 3. After the ink is poured, the ink filling port 111 needs to be sealed with a sealing plug or sealing cap.

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

[0056] like Figures 1 to 2 As shown in the embodiment of this utility model, when water is added to the water tank 13, water is added to the water tank 13 through the water inlet 131 located in the humidification tank 3. After the water is added, the water inlet 131 needs to be sealed with a sealing plug or sealing cap.

[0057] In this embodiment, the water inlet 131 is arranged on a partially raised step in the humidification chamber 3. The partially raised step design can keep the inlet of the water inlet 131 clean and prevent the ink stains of the humidification pad 31 from contaminating the water inlet and thus contaminating the operator's hands.

[0058] In embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the moisturizing compartment 3 also includes a water-absorbing tube 32, a water-absorbing rope 321, and a pen tip fixing component 33. The pen tip fixing component 33 is set on the shell 1 inside the moisturizing compartment 3, and the stored pen tip is magnetically attracted to the pen tip fixing component 33 by the magnetic structure at the end of the pen tip. The upper end of the water-absorbing tube 32 is fixedly connected to the bottom of the moisturizing compartment 3, and the lower end of the water-absorbing tube 32 extends into the depth of the water tank 13. The water-absorbing tube 32 is filled with the water-absorbing rope 321, which has a capillary structure. One end is connected to the moisturizing pad 31, and the other end extends into the depth of the water tank 13. Under capillary action, water is lifted and transported to the moisturizing pad 31 along the water-absorbing rope 321 to achieve automatic water absorption and moisturization. At the same time, the water-absorbing rope 321 can also prevent water from leaking directly from the water-absorbing tube 32 when the pencil case is tilted, so that the moisturizing compartment 3 can absorb and moisturize without spilling water, thus providing conditions for the portable nature of the pencil case.

[0059] After writing with ink, if the brush needs to be used again in a short period of time, the brush head does not need to be cleaned. Simply separate the brush head from the brush handle, and place the brush head with ink directly into the moisturizing chamber 3 for storage and moisturization. The bristles should be placed against the moisturizing pad 31 to keep the brush head moist and prevent it from drying out and hardening. The brush head can be taken out and magnetically connected to the brush handle for direct writing anytime, anywhere, eliminating the trouble of frequent brush washing. This solves the problems of difficulty in washing brushes and inconvenience in carrying them due to environmental limitations, providing great convenience for brush users, especially students.

[0060] The pen tip holder 33 magnetically secures the pen tip, ensuring it stays firmly against the moisturizing pad 31. This prevents the pen tip from falling off or moving due to shaking or tipping of the stationery box, eliminating the risk of ink stains and pen bristle damage caused by pen tip movement or detachment.

[0061] In an embodiment of this utility model, the pen barrel 4 includes a pen barrel fixing member 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 tank 11 and the water tank 13.

[0062] The pen barrel fixing component 41 is fixedly installed at the tail end of the pen barrel 4 away from the open end; the pen barrel fixing component 41 is magnetically attracted to the structural component at the end of the pen barrel, thus magnetically fixing the pen barrel in the pen barrel 4.

[0063] In this embodiment, the pen barrel end employs a magnetic structure with at least two magnetic poles and adjacent magnetic poles in opposite directions. Simultaneously, the pen barrel fixing member 41 is magnetically fixed at an eccentric position at the tail end of the pen barrel cylinder 4. When the pen barrel is inserted into the pen barrel cylinder 4, the magnetic structure at the pen barrel end automatically rotates, aligning one of the magnetic poles with the pen barrel fixing member 41 and attracting it magnetically, thus magnetically fixing the pen barrel and eliminating the need for manual positioning. Twisting the pen barrel at the open end of the pen barrel cylinder 4 causes the other adjacent magnetic pole in the magnetic structure at the pen barrel end to approach the pen barrel fixing member 41 and generate a magnetic repulsive force, pushing the pen barrel out of the pen barrel cylinder 4. Utilizing the principle that the tangential force of the two magnets is much smaller than the axial force, only a small force is needed to rotate the pen barrel.

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

[0065] In order to keep the humidification chamber 3 and ink pool 12 moist for a long time and prevent them from drying out, a cover plate 5 is installed on the top of the humidification chamber 3 and ink pool 12.

[0066] The "ink" and "ink juice" mentioned in this invention can also be replaced by other liquids. For example, if "water" is used instead of "ink", then this book painting stationery box can be used for outdoor watercolor painting or for writing practice on water-writing cloth.

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

[0068] "Button attracting component 241", "pen tip fixing component 33" and "pen barrel fixing component 41" can all be magnetic structural components or structural components made of soft magnetic materials; among the two structural components that attract and fix each other magnetically, at least one of them is a magnet or a magnetic structural component.

[0069] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
