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 moisture retention of the brush tip. The moisturizing of the brush tip is particularly critical, because once the brush tip is dry and hard, it will not only affect the writing effect, but 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:

[0024] Preferably, the air vent connects the space above the liquid level in the liquid storage tank with the outside air. When the air vent is below the liquid level in the liquid storage tank, the air vent connects the space above the liquid level in the liquid storage tank with the outside air through the air vent tube.

[0025] Preferably, the liquid storage bin is provided with a liquid filling port, and when replenishing the liquid, the liquid is poured into the liquid storage bin from the liquid filling port.

The lower end of the water adding pipe extends into the water tank and is isolated from the liquid storage tank.

[0027] Preferably, the adsorption shaft is a ferromagnetic component or a permanent magnet, and is connected to the wall of the moisturizing bin.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1 - Figure 5 , a calligraphy and painting pencil case, comprising:

[0040] Shell 1;

[0041] The partition 2 divides the space enclosed by the shell 1 into three chambers. The upper chamber of the three chambers is a liquid storage tank 11, the upper middle chamber is a storage tank 12, and the lower chamber is a water tank 13. The liquid storage tank 11 stores liquid, and the storage tank 12 stores liquid injected from the liquid storage tank 11. The liquid storage tank 11 and the storage tank 12 are separated by the partition 2.

[0042] The flow hole 21 is provided on the partition 2, and when the liquid storage tank 11 is a closed chamber, the partition 2 is provided with a vent hole 22;

[0043] The magnetic control valve 3 is arranged on the partition plate 2, and the magnetic control valve 3 controls the blocking and opening of the flow hole 21 and the air hole 22 according to the magnetic force of the magnetic component, so as to realize the flow of liquid from the liquid storage tank 11 to the storage tank 12;

[0044] The moisturizing chamber 4 is configured as an upper-opening container, and the upper edge thereof is connected to the upper surface of the housing 1, and a moisturizing pad 41 is arranged inside the container for abutting against and moisturizing the brush head;

[0045] The pen holder compartment 5 is used for storing the writing brush pen holder.

[0046] In the embodiment, the liquid storage tank 11 is used to store liquid, such as ink, and is isolated from the storage tank 12 by the partition 2. When it is necessary to inject ink into the storage tank 12, the user operates the magnetic control valve 3 and uses the magnetic force of the magnetic component to open the flow hole 21 on the partition 2 (if the liquid storage tank 11 is a closed chamber, the air vent 22 is opened at the same time to maintain air pressure balance). Under the action of gravity, the ink flows from the liquid storage tank 11 through the flow hole 21 into the storage tank 12. A moisturizing pad 41 is laid at the bottom of the moisturizing tank 4, which has a capillary action and can absorb and retain moisture. The upper end of the water suction pipe 43 is fixed to the bottom plate of the moisturizing tank 4, and the lower end extends close to the bottom plate of the water tank 13. The water in the water tank 13 is transported to the moisturizing pad 41 by capillary action through the water suction rope 431 in the water suction pipe 43. The brush head is stored in the moisturizing tank 4 and abuts against the moisturizing pad 41 to keep it moist. The pen holder compartment 5 is used to store the writing brush pen holder. The user can insert the writing brush pen holder into the pen holder cavity 51 and fix and remove the pen holder through magnetic effect.

[0047] The rapid and accurate circulation of ink is achieved through the magnetic control valve 3, avoiding the cumbersome operation of traditional manual pouring or injection. The design of the moisturizing chamber 4 allows the brush tip to remain moist at any time without the need for frequent cleaning by the user. The capillary action of the moisturizing pad 41 can continuously provide moisture to the brush tip to prevent the brush tip from being damaged due to drying. The separation design of the liquid storage chamber 11 and the storage chamber 12, as well as the ingenious arrangement of the circulation holes 21 and the air holes 22, achieve efficient use and storage of ink. The existence of the pen barrel chamber 5 allows the brush barrels to be stored in an orderly manner, which is convenient for users to quickly access and replace. The sturdy design of the shell 1 and the partition 2, as well as the precise construction of the magnetic control valve 3 and the pen barrel chamber 5, ensure the overall durability and service life of the pencil case. The pencil case integrates multiple functions such as ink storage and circulation, pen tip moisturizing, and pen barrel storage, reflecting an innovative design concept. Its design fully considers the actual needs of calligraphy and painting enthusiasts, and is highly practical and convenient.

[0048] In an embodiment of the present invention, the magnetic control valve 3 comprises:

[0049] The button adsorbing member 31 is arranged on one side of the partition 2;

[0050] The blocking cavity 32 is fixed to one side of the partition 2 to form a barrier for the blocking member 33, regulating the movement and range of the blocking member 133 when it is turned over and tilted; an outlet is provided to communicate with the storage bin 12;

[0051] The blocking member 33 is disposed in the blocking cavity 32 and cooperates with the button adsorption member 31 through magnetic adsorption to achieve blocking of the flow hole 21 and the air vent 22;

[0052] The button cavity 34 is close to or arranged on the other side of the partition 2. The button cavity 34 and the blocking cavity 32 are respectively located on both sides of the partition 2, and one end is open and fixedly connected to the housing 1, and the button cavity 34 is isolated from the liquid storage bin 11;

[0053] The button 35 is disposed in the button cavity 34 , and by pressing the button 35 , the blocking member 33 is flipped and lifted to open the flow hole 21 and the vent hole 22 .

[0054] In this embodiment, the cavity wall of the blocking cavity 32 is formed by the partition 2, and the partition 2 presents an irregular shape at the position of the magnetic control valve 3. From a topological point of view, the blocking cavity 32 can be regarded as the topological structure of the partition 2, and the cavity wall of the blocking cavity 32 is a deformation of the partition 2 and is still a part of the partition 2; similarly, the cavity wall of the button cavity 34 is also formed by the partition 2.

[0055] In the initial state, the blocking member 33 cooperates with the button adsorption member 31 through magnetic adsorption to tightly block the flow hole 21 and the air hole 22 (if the liquid storage tank 11 is a closed chamber, the air hole 22 also needs to be blocked). When the user needs to make the liquid flow from the liquid storage tank 11 into the storage tank 12, press the button 35, and the blocking member 33 flips up under the action of magnetic repulsion, thereby opening the flow hole 21 and the air hole 22. Under the action of gravity, the ink flows from the liquid storage tank 11 through the flow hole 21 into the storage tank 12. If the liquid storage tank 11 is a closed chamber, the opening of the air hole 22 is used to maintain air pressure balance.

[0056] The user only needs to press the button 35 to open the circulation hole 21 and the vent hole 22, which is easy to operate. The blocking member 33 cooperates with the button adsorbent 31 through magnetic adsorption to achieve stable blocking of the circulation hole 21 and the vent hole 22 to prevent liquid leakage. Since the button 35 needs to be clearly pressed to open the circulation hole 21 and the vent hole 22, liquid leakage caused by misoperation is effectively prevented. The magnetic control valve 3 uses the design of magnetic adsorption and magnetic repulsion to reduce the risk of mechanical wear and damage, and improve the overall durability and service life of the pencil case.

[0057] In the embodiment of the magnetic control valve 3 of the present invention, the blocking member 33 is fixedly installed with a blocking adsorbent 331, which corresponds to the position of the button adsorbent 31 and is magnetically attracted to the button adsorbent 31 in the initial state; the button 35 is fixedly installed with the button adsorbent 31 and the button magnet 351, the button adsorbent 31 and the blocking adsorbent 331 are magnetically attracted, the button magnet 351 and the blocking adsorbent 331 are magnetically repelled, and the travel path of the button 35 is in the magnetic field of the blocking adsorbent 331. When the button 35 is pressed, the button adsorbent 31 moves away from the blocking adsorbent 331 and the button magnet 351 approaches the blocking adsorbent 331, so that the blocking member 33 is flipped and tilted to open the flow hole 21 and the air vent 22.

[0058] In this embodiment, the magnetic control valve 3 adopts a solution in which the button adsorption member 31 is movable, that is:

[0059] The blocking piece 33 is fixedly installed with a blocking adsorbent 331, which is a permanent magnet. The button 35 is fixedly installed with the button adsorbent 31 and the button magnet 351 from front to back (relative to the direction of movement of the button). The button magnet 351 is a permanent magnet and magnetically repels the blocking adsorbent 331. The button adsorbent 31 is a permanent magnet or a ferromagnetic component. In the initial state, the button adsorbent 31 and the blocking adsorbent 331 correspond in position and are magnetically attracted to each other. The blocking piece 33 is sucked against the partition 2 to form a stable blockage of the flow hole 21 and the air vent 22; the magnetic field of the blocking adsorbent 331 is on the travel path of the button 35. When the button 35 is pressed, the button adsorbent 31 moves away from the blocking adsorbent 331 while the button magnet 351 approaches the blocking adsorbent 331. The blocking adsorbent 331 is affected by the magnetic repulsion, so that the blocking piece 33 flips and tilts up to open the flow hole 21 and the air vent 22.

[0060] The advantages of the magnetic control valve 3 are: first, the number of magnets or adsorbents is small, reduced to 3, and the cost is low; second, when the blocking member 33 is flipped and tilted, since there is no magnetic attraction, the magnetic strength of the blocking adsorbent 331 and the button magnet 351 can be significantly reduced.

[0061] There are different ways of flipping and tilting the blocking piece 33. The side from which the blocking piece 33 flips and tilts depends on the constraint form of the blocking cavity 32 on the blocking piece 33 and has nothing to do with the direction in which the button 35 approaches. This embodiment constrains the distal end of the blocking piece 33 (relative to the direction of movement of the button) and allows the proximal end of the blocking piece 33 to flip and tilt. Its advantage is that when the blocking piece 33 is pushed to the distal end by the repulsive force, the distal end of the blocking piece 33 rotates instead of sliding on the wall of the blocking cavity 32, fundamentally preventing flipping and tilting or resetting failure caused by sliding dislocation or excessive sliding friction resistance.

[0062] In the above-mentioned embodiment of the magnetic control valve 3, as long as the moving distance of the button 35 is controlled, that is, the relative position of the button magnet 351 and the blocking adsorbent 331 is controlled, when the button 35 is released, the button 35 will automatically reset to the initial position and be magnetically locked under the action of the magnetic repulsion force. As the button 35 is reset, the magnetic attraction between the blocking adsorbent 331 and the button adsorbent 31 comes into play again, so that the blocking part 33 is re-adsorbed to the blocking position. The self-resetting function of the magnetic control valve 3 makes the magnetic control valve simpler and more practical, and improves the convenience and efficiency of use.

[0063] In an embodiment of the present invention, the air hole 22 connects the space above the liquid surface of the liquid storage tank 11 with the outside air; when the air hole 22 is below the liquid surface of the liquid storage tank 11, the air hole 22 connects the space above the liquid surface of the liquid storage tank 11 with the outside air through the air vent tube 221.

[0064] In this embodiment, for the sealed liquid storage tank 11, the air hole 22 is set to achieve the balance of air pressure inside and outside the liquid storage tank 11, and to prevent the formation of negative pressure in the liquid storage tank 11, which will prevent the ink from flowing out. The air hole 22 is set at an appropriate position of the partition 2, usually above the liquid level of the liquid storage tank 11, to ensure that the space above the liquid level of the liquid storage tank 11 is connected to the outside air; when the air hole 22 is below the liquid level of the liquid storage tank 11, it is necessary to use the air vent 221, one end of which is connected to the air hole 22, and the other end extends to the liquid level of the liquid storage tank 11, to form a passage for the space above the liquid level to ventilate the outside. When opening the circulation hole 21, the air hole 22 must be opened at the same time to inject ink from the liquid storage tank 11 into the storage tank 12; conversely, in order to prevent the liquid storage tank 11 from leaking ink when it is tilted and shaken, the circulation hole 21 and the air hole 22 must be closed at the same time, so the range of the blocking member 33 should be able to completely cover the circulation hole 21 and the air hole 22 at the same time.

[0065] like Figure 1 to Figure 2 As shown, in an embodiment of the present invention, when the liquid storage tank 11 is replenished with ink, ink is poured into the liquid storage tank 11 from a liquid filling port 111 disposed in the moisturizing tank 4 .

[0066] In this embodiment, the liquid filling port 111 is arranged in the moisturizing chamber 4, so that the appearance of the calligraphy and painting pencil case is more simple and beautiful. The liquid filling port 111 is arranged on a partially raised step. The upper edge height of the liquid filling port 111 is slightly lower than the height of the outer shell 1. After the ink is filled, there is enough space above the liquid level in the liquid storage chamber 11 so that the air vent 221 can always extend out of the liquid surface. The partially raised step design also keeps the liquid filling port 111 clean to prevent the ink on the moisturizing pad 41 from contaminating the operator's hands; the liquid filling port 111 is equipped with a sealing plug or a sealing cover.

[0067] like Figure 1 to Figure 2As shown, in an embodiment of the present invention, when the water tank 13 is replenished with water, water is poured into the water tank 13 from the inlet of the water adding pipe 131 arranged in the moisturizing tank 4, and the lower end of the water adding pipe 131 extends into the water tank 13 and is isolated from the liquid storage tank 11.

[0068] In this embodiment, when it is necessary to replenish water for the water tank 13, water is poured into the water tank 13 through the inlet of the water adding pipe 131. The inlet of the water adding pipe 131 is arranged on a partially raised step in the moisturizing tank 4, and the lower end extends into the water tank 13; the water adding pipe 131 is isolated from the liquid storage tank 11, forming an independent water system and ink system for the calligraphy and painting pencil case. The water in the water tank 13 is supplied to the moisturizing box 4 to infiltrate the moisturizing pad 41, and the ink in the liquid storage tank 11 is supplied to the storage tank 12 for writing. The partially raised step design can keep the inlet of the water adding pipe 131 clean, prevent the ink of the moisturizing pad 41 from contaminating the water adding port and then contaminating the operator's hands; the inlet of the water adding pipe 131 is equipped with a sealing plug or a sealing cover.

[0069] like Figure 1 , Figure 2 As shown, in an embodiment of the present invention, the moisturizing bin 4 includes:

[0070] The adsorption shaft 42 is a ferromagnetic component or a permanent magnet, and is connected to the wall of the moisturizing chamber 4. The stored pen tip is adsorbed on the adsorption shaft 42 by the magnetic column at the end of the pen tip. Under the action of gravity, the pen tip falls around the adsorption shaft 42 and abuts against the moisturizing pad 41.

[0071] The water suction pipe 43 has an upper end fixedly connected to the bottom plate of the moisturizing bin 4 and a lower end extending close to the bottom plate of the water bin 13; the water suction pipe 43 is filled with a water suction rope 431, which has a capillary structure, one end of which is connected to the moisturizing pad 41 and the other end of which extends to the bottom of the water bin 13 to achieve automatic water absorption and moisturizing;

[0072] In this embodiment, the moisturizing bin 4 includes an adsorption shaft 42 and a water absorption pipe 43; the adsorption shaft 42 is a ferromagnetic component or a permanent magnet, and the shaft is connected or fixedly connected to the bin wall of the moisturizing bin 4; the brush does not need to be cleaned if it is used again in a short period of time after being dipped in ink for writing. The brush head with ink can be directly placed in the moisturizing bin 4 for storage and moisturization. The brush head to be stored is held and the magnetic column at the end of the brush head is pressed against the adsorption shaft 42 for magnetic fixation. Under the action of gravity, the brush head falls around the adsorption shaft 42 and presses against the moisturizing pad 41, so that the brush head remains moist and prevents the brush head from drying and hardening; when using it again, the brush head can be removed from the adsorption shaft 42 and connected to the pen holder for direct writing, which saves the trouble of frequent brush washing and solves the trouble of brush washing and carrying due to environmental conditions, providing great convenience for brush users, especially students.

[0073] The upper end of the water suction pipe 43 is fixedly connected to the bottom plate of the moisturizing bin 4, and the lower end extends close to the bottom plate of the water bin 13; the water suction pipe 43 serves as a carrier of the water suction rope 431, in which the water suction rope 431 is stuffed, one end of the water suction rope 431 is connected to the moisturizing pad 41, and the other end extends to the bottom of the water bin 13; the water suction rope 431 has a capillary structure and has good water absorption performance. It can automatically absorb water from the water bin 13 through capillary action and transfer the water to the moisturizing pad 41 to achieve automatic water absorption and moisturizing; the water suction rope 431 can lift water from the lower water bin 13 to the bottom plate of the moisturizing bin 4 to infiltrate the moisturizing pad 41 through capillary action, and can also block water from leaking out of the water suction pipe 43 when the calligraphy and painting pencil case is overturned, so that the moisturizing box 4 can absorb water and moisturize without leaking, which provides conditions for the calligraphy and painting pencil case to be portable.

[0074] The moisturizing box 4 has the functions of moisturizing and temporary storage. The pen tip can continuously absorb moisture from the moisturizing pad 41, effectively preventing the ink in the pen tip from drying up. The pen tip no longer needs to be cleaned frequently, which saves time and effort, extends the service life of the pen, and improves the user experience.

[0075] like Figure 1 , Figure 2 As shown, in an embodiment of the present invention, a ratchet mechanism 421 is provided at least at one end of the adsorption shaft 42 to constrain the adsorption shaft 42 to make one-way rotation, so that the pen tip can only make one-way rotation in the direction of abutting the moisturizing pad 41; the ratchet mechanism 421 utilizes magnetic attraction to keep the pawl and the ratchet in continuous contact, wherein the pawl and the ratchet are composed of permanent magnets or ferromagnetic components, and are magnetized by the magnetic column at the end of the pen tip.

[0076] In this embodiment, under the constraint of the ratchet mechanism 421, it is ensured that the pen tip can always be stably attached to the moisturizing pad 41, and the pen tip will not fall off or move due to the shaking or tipping of the calligraphy and painting pencil case, eliminating the risk of ink contamination and damage caused by shaking or falling of the pen tip.

[0077] In the embodiment of the pen barrel cartridge 5 of the present invention:

[0078] When at least two permanent magnet columns are fixedly installed on the concentric circle position of the pen end and the magnetic poles of adjacent magnetic columns are opposite, the pen cartridge 5 includes:

[0079] The pen holder cavity 51 is in the shape of a tube with one end sealed and the open end connected to the housing 1 . It is used for storing the brush holder and is isolated from the liquid storage tank 11 and the water tank 13 .

[0080] The sealing end magnet 511 is fixedly installed at the sealing end of the pen shaft cavity 51. It is a permanent magnet. It corresponds to one of the magnetic columns at the end of the pen shaft and is magnetically attracted to the other. When the pen shaft is twisted, the sealing end magnet 511 and the adjacent magnetic column at the end of the pen shaft generate a magnetic repulsive force, pushing the pen shaft out of the pen shaft cavity 51.

[0081] Specifically, it is first required that there are no less than two magnetic columns at the end of the pen shaft, and the magnetic poles of the two magnetic columns are opposite; when the pen shaft is inserted into the pen shaft cavity 51, there must be a magnet at its end that will be magnetically attracted to the sealing end magnet 511, thereby magnetically fixing the pen shaft. In particular, under the condition that the magnetic columns at the end of the pen shaft are sufficiently close to each other, the pen shaft will automatically rotate and align when approaching the sealing end, so that the magnetic columns of opposite polarities attract each other, eliminating the trouble of manually finding the position angle. When the pen shaft needs to be taken out, the pen shaft in the pen shaft cavity 51 is rotated, and the magnetic columns at the end of the pen shaft can be aligned with the sealing end magnet 511 in turn. Using the principle that the tangential force of the two magnets is much smaller than the axial force, only a very small force is needed to rotate the pen shaft, and the magnetic columns at the end of the pen shaft are aligned with the sealing end magnet 511 in turn. There must be a magnetic column at the end of the pen shaft that magnetically repels the sealing end magnet 511 and approaches the sealing end magnet 511, and the pen shaft will be pushed out by the magnetic repulsion force.
