Description

Technical Field

[0001] This utility model relates to a writing instrument, namely a sealed, wash-free, and moisturizing brush holder. Background Technology

[0002] A calligraphy brush mainly consists of a handle and a brush head. The brush head is dipped in ink or paint for writing and painting. However, after use, the brush head usually needs to be washed with water and hung upside down on a brush holder. This is wasteful of ink and paint, as well as water and labor, making it quite troublesome. If the brush head is not washed, it will solidify. When used again, it needs to be dissolved with water, which takes a long time, causing great inconvenience when writing urgently. To solve this problem, people made a cap from a sealed material to cover the brush head, which can prevent air circulation and prolong the solidification time. Obviously, this cap must fit tightly with the brush head and handle to prevent air circulation. However, the diameter of the middle part of a used brush head is often larger than the diameter of the handle, and the diameter of the cap must be smaller than the diameter of the brush head to fit the handle, making it difficult to insert the brush head. Therefore, existing brush caps are mostly made in a pointed shape, with an opening diameter larger than the diameter of the handle and brush head. In this way, the brush head can be inserted smoothly, but the opening of the cap is not tightly sealed, and the moisturizing time is shorter. The middle of the pen cap can also compress the brush tip from the opposite direction, damaging the bristles. Furthermore, in recent years, some have suggested soaking used brushes in water or placing them in steam to keep them soft for a long time. Experiments have shown that this method significantly damages the bristles, reducing their resilience, making the brush handle prone to cracking and deformation, causing the brush tip to easily fall off, and drastically shortening the brush's lifespan. For high-end brushes, the cost of such damage is very high. Therefore, we need a tool that doesn't require washing, can keep the brush tip moist for a longer period without drying out, is easy to use, and won't damage the brush tip. Summary of the Invention

[0003] The purpose of this invention is to provide a sealed, wash-free, moisturizing brush holder that can keep the brush tip moist for a long time without washing it after use, preventing it from hardening and maintaining proper moisture without damaging the brush due to excessive moisture.

[0004] The above objective is achieved by the following technical solution: providing a sealed, wash-free, moisturizing calligraphy brush holder, characterized in that: the brush holder has a tubular brush holder made of a sealed material, the inner diameter of the brush holder is larger than the diameter of the brush handle and the brush head, the lower end of the brush holder is sealed, and the upper opening is provided with an openable and sealable top cover, the top cover is provided with an insertion hole in the middle, and the insertion hole and the brush handle are in a sliding but airtight tight fit.

[0005] The pen holder and the top cover are connected by threads. There is a sealing gasket between the top cover and the top opening of the pen holder. An elastic plug is embedded in the insertion hole of the top cover. The inner diameter of the elastic plug in its natural state is smaller than the outer diameter of the pen handle.

[0006] A thin-walled sealing tube made of a sealing material is installed inside the socket of the top cover. The inner diameter of the sealing tube is larger than the diameter of the brush handle, and the outer diameter of the sealing tube is sealed to fit the socket of the top cover.

[0007] The top cover is an elastic plug, which is a cone shape that is thicker at the top and thinner at the bottom. The diameter of its upper end is larger than the top opening of the pen holder, and the diameter of its lower end is smaller than the top opening of the pen holder.

[0008] The pen holder has a base at its lower end, and the area occupied by the base is larger than the horizontal cross-sectional area of ​​the pen holder.

[0009] There are multiple pen holders, and the bases of each pen holder are connected.

[0010] The base is a water tank that can hold water. There is a partition between the water tank and the pen holder. The partition has open convection holes. The water tank is equipped with a solar collector.

[0011] The solar collector has a double-layered vacuum glass panel installed on the upper side of the water tank.

[0012] A condenser lens is mounted above the double-layered vacuum glass plate.

[0013] The beneficial effects of this invention are: the diameter of the pen holder is larger than the diameter of the pen tip, making it easy to insert the pen tip without damage. The pen holder is small and sealed, preventing moisture loss and condensation from the pen tip. Furthermore, the pen tip maintains appropriate moisture levels, preventing excessive moisture from reducing the performance of the brush bristles. Therefore, the pen tip can be inserted into the pen holder without cleaning and can be removed for use at any time, saving time and water and significantly reducing the difficulty of using a calligraphy brush. Moreover, its simple structure, low cost, and ease of use make it a promising essential accessory for calligraphy brushes. Attached Figure Description

[0031] First embodiment: Figure 1 , Figure 2 An airtight, moisture-retaining brush holder is introduced. This brush holder 1 has a tubular brush holder 2 made of airtight material. The inner diameter of the brush holder is larger than the diameter of the brush handle 6 and the brush head. The lower end of the brush holder is sealed, and the upper opening is provided with a cover 4 that can be opened and sealed. The cover has an insertion hole 5 in the middle. The insertion hole and the brush handle are in a sliding but airtight fit.

[0032] When using, such as Figure 3As shown, first remove the top cover from the pen holder. Insert the brush handle (without cleaning the brush tip after writing or painting) into the slot on the top cover, then insert the brush tip into the pen holder. Tighten the top cover onto the top opening of the pen holder. Because the pen holder is an airtight, sealed structure, the space between the top cover and the top opening of the pen holder, as well as between the slot and the brush handle, is also airtight. Air cannot escape, so the moisture on the brush tip is not easily lost, keeping the brush tip moist for a long time, and preventing the ink or paint from solidifying. When you need to use the brush again, open the top cover, remove the brush handle, and you can write or paint as usual without adding water to dissolve the ink.

[0033] Furthermore, since there is no water inside the pen holder, the water content of the brush tip will decrease slightly for the first few hours after the brush is placed inside. Subsequently, humid air forms inside the pen holder, and the humidity of the brush tip stabilizes for a relatively long period of time, allowing it to be used immediately after 2-3 days. Due to the appropriate humidity around the brush tip, the pen handle will not deform, and the performance of the brush bristles will not be diminished.

[0034] The second embodiment is an improvement upon the first embodiment. For example... Figure 4 , Figure 5 As shown, the pen holder 2 and the top cover 4 are connected by threads, making the connection more secure. There is a sealing gasket 8 between the top cover and the top opening of the pen holder, which provides a better seal. The insertion hole 5 of the top cover is fitted with an elastic ring 7. The inner diameter of the elastic ring in its natural state is smaller than the outer diameter of the brush handle, resulting in a better seal between the elastic ring and the brush handle. Moreover, it can be used with brush handles of different diameters, making it suitable for both large and small brushes.

[0035] Furthermore, the lower end of the pen holder 2 is equipped with a base 3, the diameter of which is larger than the diameter of the pen holder. The brush holder is very stable when placed on a table, making it more convenient to use.

[0036] The third embodiment is an improvement upon the aforementioned embodiments. For example... Figure 6 As shown, the pen holder's wall is made of transparent thin-walled resin, plastic, and glass, and the inner diameter of the pen holder is 8-10mm larger than the diameter of the brush tip. It is small in size and lightweight. After installation, it can be laid flat, or as shown in the picture, the brush can be hung under the pen holder 12, making it convenient for storage and use.

[0037] The fourth embodiment: Based on the aforementioned embodiments, improvements were made to the structure related to the sealing performance of the pen barrel. For example... Figure 7 As shown, a thin-walled sealing tube 10 made of a hermetically sealed material is fitted into the insertion hole 5 of the upper cover 4. Combined with... Figure 8As can be seen, the sealing tube, with an inner diameter slightly larger than the brush handle, fits snugly over the brush handle, sealing the bamboo or wooden handle. It is inserted into the insertion hole 5 along with the brush. This makes the entire brush handle airtight, preventing moisture from escaping and extending the moisture retention time. Simultaneously, a seal must also be maintained between the sealing tube and the insertion hole. Therefore, the outer diameter of the sealing tube must also achieve a tight fit with the insertion hole 5 on the top cover. The sealing tube may be inserted through the elastic ring of the insertion hole, or, as shown in the diagram, above the elastic ring. Regardless of its placement, a tight seal must be maintained to prevent gas from escaping.

[0038] Of course, this type of sealing tube is only suitable for pen barrels made of materials with poor sealing properties, such as bamboo and wood. For pen barrels made of non-breathable materials, such as metal or plastic, there is no need to use this sealing tube. However, bamboo and wood still make up the vast majority of pen barrels, so the market prospects for this type of sealing tube are quite promising.

[0039] Fifth embodiment: An improvement is made to the top cover of the pen holder based on the first embodiment. For example... Figure 9 As shown, the upper cover 4 of the pen holder 2 is a resilient plug 11. The resilient plug is a cone that is thicker at the top and thinner at the bottom, with its upper diameter larger than the upper opening of the pen holder and its smaller diameter smaller than the upper opening of the pen holder. The resilient plug also has a hole in the middle, however, in its natural state, the diameter of the hole should be much smaller than the diameter of the pen barrel.

[0040] When using, such as Figure 10 As shown, insert the pen barrel into the socket of the elastic plug, ensuring a tight fit between the socket and the pen barrel. Then, insert the pen barrel and elastic plug into the pen holder, where the elastic plug presses firmly against the top of the pen holder, creating a highly airtight seal. Clearly, this type of elastic plug has a simpler structure, better sealing performance, and is very convenient to use.

[0041] In addition, if a longer period of hydration is needed, a small amount of water can be added to the pen holder. The amount of water should not be too much; ideally, it should completely vaporize within the holder immediately. Even if it doesn't completely vaporize, the pen tip should not be submerged in the water; maintain a distance of at least 20mm between the pen tip and the water surface. Because the pen holder is well-sealed, the added water and the resulting vapor are less likely to escape, thus extending the hydration time. However, for underage students, controlling the amount of water in the pen holder is difficult. Especially with pen holders made of opaque materials, the depth to which the pen is inserted is also difficult to control. Adding too much water will damage the brush, resulting in more harm than good. Therefore, if writing is frequent, with intervals not exceeding 3 days, there is no need for prolonged hydration, and thus no need to add water.

[0042] Sixth embodiment: The structure of the pen holder is improved based on the aforementioned embodiments. For example... Figure 11As shown, there are multiple pen holders 2, and their bases 3 are connected. The multiple pen holders can be arranged in a straight line, in a circle, or in other forms. In use, as... Figure 12 As shown, multiple pen holders can hold multiple calligraphy brushes, and different types of calligraphy brushes can be inserted separately as needed.

[0043] The seventh embodiment: Improvements are made to the water-addition method and structure of the pen holder based on the aforementioned embodiments. In embodiments one through four, no water is added to the pen holder. Embodiment five only proposes adding a suitable amount of water, without exclusion. The method of not adding water achieves moisturization by preventing water loss from the brush tip through a sealed environment; this is commonly referred to as "dry moisturization." The reason for proposing "dry moisturization" is that prolonged soaking of the brush in water reduces the toughness of the bristles, making it overly soft and lacking elasticity when writing. Furthermore, most brushes currently use bamboo or wood handles, which are permeable to water; prolonged soaking will cause deformation and cracking, especially the brush tip, which is prone to coming unglued. Additionally, in low room temperature or opaque pen holders, insufficient heat inside prevents the water from evaporating sufficiently, thus hindering its effectiveness. However, adding water also offers significant advantages, significantly increasing the moisturizing time, making it a worthwhile goal. Our aim is to maximize the advantages and minimize the disadvantages, extending the moisturizing time while ensuring ease of operation and preventing damage to the brush.

[0044] Therefore, this example proposes a new technical solution: such as Figure 13 As shown, the base 3 of the pen holder has a hollow cavity inside, which is a water tank 14 that can hold water. A partition 18 separates the water tank from the pen holder, and the partition has open convection holes 19. The water tank is equipped with a solar collector 15.

[0045] There are various types of solar collectors, such as vacuum tube collectors and flat-plate collectors. Since these are all mature technologies, they will not be described in detail here. Below is only an example of a simple solar collector. As shown in the figure, one side of the base extends outwards, and the cavity inside the base is the water tank. The upper side of the water tank is preferably a slope, on which a double-layered vacuum glass plate 16 with good light transmission is installed. The water tank below the glass plate is filled with a small amount of clean water. The bottom and surrounding area of ​​the water tank should be insulated with a material with good thermal insulation properties. Alternatively, heat-absorbing materials such as aluminum plates can be embedded in the inner wall of the water tank to enhance the absorption rate of sunlight.

[0046] When using, such as Figure 14As shown, used brushes can be inserted into the brush holder without washing. If the brushes need to be left unused for 2-3 days, there's no need to consider using the solar collector. If the brushes need to be left unused for a longer period, this brush holder can be placed in a sunny location. Sunlight shines through the glass plate onto the water, which absorbs the sunlight's energy and raises its temperature. Because the glass plate is in a high vacuum, the water's heat is not easily dissipated, and the water temperature continues to accumulate, increasing the water vaporization rate. The generated water vapor then enters the brush holder through convection hole 19. Subsequently, because the brush holder is far from the heat source and has a relatively large heat dissipation area, its temperature is lower than that of the water tank. The water vapor condenses into water droplets at the lower temperature and flows back to the water tank through convection hole 19. Since the specific gravity of water vapor is much smaller than that of water droplets, air-water convection can occur through one convection hole. However, for smoother convection, as shown in the diagram, a larger convection hole can be made in the middle of the partition 18, and several smaller convection holes can be made around the perimeter of the partition. Most of the gas will rise into the brush holder from the large central convection hole. The water droplets condensing inside the pen holder can flow down the inner wall and back into the water tank through the small convection holes. Since the pen holder itself can remain moist for 2-3 days, even a short period of sunlight each day to replenish the moisture will meet the need for long-term hydration. Although the homemade equipment used in the experiment had only moderate airtightness, the pen tip remained well-hydrated and could be used at any time within three months. Therefore, the technical solution in this example is highly feasible.

[0047] Experiments have shown that the water temperature during this vaporization process generally does not exceed 40℃, and the water tank is filled with a small amount of water, resulting in low internal pressure. Furthermore, the connections between the pen barrel and the cap, and between the cap and the pen holder, are all elastic, ensuring safety. Of course, for added security, a safety valve can be installed on the pen holder or water tank. Since safety valves are standard technology, they will not be discussed further here.

[0048] Eighth embodiment: Based on the seventh embodiment, the structure of the solar collector is improved. For example... Figure 15 , Figure 16 As shown, the base 3 below the pen holder 2 is a water tank 14, with a partition 18 between the water tank and the pen holder. The partition has convection holes 19. The water tank extends to one side and is covered by a double-layered vacuum glass plate 16, forming a solar collector 15. An improvement is the addition of a condenser lens 19 above the double-layered vacuum glass plate 16. The condenser lens illustrated is a convex lens, mounted on a bracket, whose position and tilt angle can be adjusted.

[0049] When in operation, place this brush holder in a sunny location, adjust the focus so that the focal point of the convex lens is in the water, and the water temperature will rise relatively quickly. Above 30℃, rising gas will be visible, and above 50℃, vaporization becomes even more vigorous. At this point, heat collection and dissipation are nearly balanced, representing the optimal state for operation. In this state, the gas pressure inside the water tank is slightly higher than the external pressure, but the elastic connection between the brush handle and the top cover, and between the top cover and the brush holder, remains stable, indicating safe operation. Of course, for added safety, a safety valve can be installed on the brush holder or water tank. Since safety valves are standard technology, we will not elaborate further here.
