Description

Technical Field

[0001] This invention belongs to the field of calligraphy brush care and relates to calligraphy brush care devices. Background Technology

[0002] The writing brush is one of the most important tools in traditional Chinese culture, with a history dating back to the Shang Dynasty more than 3,000 years ago. Today, the writing brush remains an important tool for Chinese calligraphy, painting, and other cultural arts, and has become one of the important symbols of Chinese culture. The conventional structure of a writing brush, from top to bottom, consists of the brush tip, brush handle, brush holder, and brush head (brush root, brush waist, brush tip, and brush end).

[0003] Calligraphy brushes require regular cleaning and maintenance to ensure their proper use and extend their lifespan. The inventor discovered during his calligraphy studies that if a brush is not thoroughly cleaned, ink residue remains inside the brush head. Once the ink dries, the brush hairs harden, lose elasticity, and shorten the brush's lifespan. Hardening near the base of the brush causes it to lose its sharpness. For pure wolf hair brushes, if not cleaned for two days, the brush will lose its sharpness and become unusable, especially when writing small regular script, where the brush tip requires exceptional precision.

[0004] Daily brush care requires:

[0005] 1. Moisten the brush before use;

[0006] 2. Clean after use;

[0007] 3. Air dry; gently wipe away the moisture with a clean towel or paper towel, then hang the brush on a brush rack in a well-ventilated and dry place;

[0008] 4. Storage: The tip of the brush should be kept dry. Do not allow the bristles to press against each other. It is best to store it in a special brush holder.

[0009] Currently, the commonly used methods are to use a brush washer or to wash directly under a tap. In the process of developing this invention, the inventors discovered that the prior art has at least one of the following technical problems:

[0010] A. Current methods of cleaning calligraphy brushes require a large amount of water to clean them, and the water used to clean the brushes will also contaminate the sink and washbasin, requiring further cleaning of the washbasin.

[0011] B. When washing the brush, your hands will also get covered in black ink, so you need to wash your hands again.

[0012] C. In addition to the above problems, the most important issue is that stirring the brush in a brush washer or rinsing it under a tap can easily deform or bend the brush bristles, reducing writing quality and shortening the lifespan of the brush.

[0013] D. Existing technologies disclose many devices for cleaning calligraphy brushes. For example, CN108583064A uses rotating water flow in a brush washing tube to wash brushes, which can cause great damage to the brush tip. CN113650440A discloses a protective calligraphy brush cleaning machine, but the structure of this cleaning machine is extremely complex and the production cost is too high, so it does not have market application prospects. Summary of the Invention

[0014] Therefore, the present invention aims to provide a brush care device that facilitates cleaning of brushes and is also convenient for carrying brushes.

[0015] Through long-term exploration and experimentation, as well as numerous trials and efforts, the inventors have continuously reformed and innovated to solve the above-mentioned technical problems. The technical solution provided by this invention is to provide a brush care device, including a pipe for inserting a brush, wherein after the brush is inserted into the pipe, a gap is left between the inner wall of the pipe and the brush.

[0016] Furthermore, the pipeline is equipped with a cleaning section with a flexible pipe wall.

[0017] Preferably, the inner diameter of the cleaning section is 0.1 to 3 cm larger than the diameter of the pen holder.

[0018] Preferably, the wall thickness of the cleaning section is 0.5~3mm.

[0019] Furthermore, the pipeline is configured from top to bottom as a water receiving section, a water storage section, a cleaning section, and a drainage section, and the water receiving section, water storage section, cleaning section, and drainage section are integrated into one unit.

[0020] Furthermore, the pipeline is configured from top to bottom as a water receiving section, a water storage section, a cleaning section, and a drainage section, and some or all of the water receiving section, water storage section, cleaning section, and drainage section are configured as detachable pipe sections.

[0021] Preferably, the total length of the water receiving section, water storage section, cleaning section, and drainage section is greater than the length of the brush, and the total length of the water storage section, cleaning section, and drainage section is less than the length of the brush.

[0022] Preferably, the water receiving section is a side-opening funnel with a fixed shape.

[0023] Preferably, the water receiving section is made of a flexible material. Under no external force, the water receiving section is a pipe section with longitudinal seams, and under external force, it deforms into a side-opening funnel with longitudinal seams.

[0024] Preferably, a crack-stopping part is provided at the bottom end of the longitudinal seam.

[0025] Preferably, the crack-stopping part is a crack-stopping hole.

[0026] More preferably, the anti-crack hole is a circular hole, an elliptical hole, or a slot.

[0027] Preferably, the water receiving section is provided with an annular folding part and a stabilizing part, with the stabilizing part located at the uppermost end of the pipe.

[0028] Preferably, the thickness of the folded portion is 30% to 80% of the wall thickness of the water receiving section.

[0029] Preferably, the water receiving section is provided with a stabilizing part, which is located at the uppermost end of the pipe.

[0030] Furthermore, the stabilizing portion is symmetrically cut off at the corners on both sides of the longitudinal seam.

[0031] Preferably, after the cut-off portion is removed, the remaining edge of the stabilizing portion is a straight line, an arc, a parabola, an ellipse, or two straight lines connecting the rounded corners.

[0032] Preferably, the stabilizing portion is folded towards the outer wall of the pipe along the folded portion.

[0033] Preferably, the stabilizing part is provided with a through hole, which is located on the symmetry plane of the stabilizing part.

[0034] Preferably, a stabilizing plate is installed at the top of the stabilizing part.

[0035] Preferably, the stabilizing plate is provided with a pen clip for holding the pen tube.

[0036] Compared with the prior art, one of the above technical solutions has the following advantages:

[0037] a) Although the structure of this invention is extremely simple, it breaks away from the design thinking of conventional brush cleaning devices. With a minimalist structure, it achieves extremely low manufacturing costs and better cleaning results. In addition to having a cleaning function, it is also easy to carry and store brushes. Compared with the various complex brush cleaning devices disclosed in existing literature and the brush cleaning tools commonly used in calligraphy and painting, this invention has more practical value and commercial application prospects.

[0038] (b) The brush care device of the present invention uses a pipe for cleaning the brush. The tip of the brush is first inserted into and passes through the pipe, so that the brush head is completely inside the pipe. Water is then introduced into the pipe to rinse the brush head in a forward direction. All the water entering the pipe flows through the brush head and carries away the ink or pigment on the brush head, improving the utilization rate of the water flow. The direction of water flow is the same as the direction of the brush hairs, that is, rinsing the brush head in the direction of the brush hairs, so as not to damage the brush head.

[0039] c) When cleaning brushes using a pipe, the amount of water flowing into the pipe cannot exceed the flow rate between the inner wall of the pipe and the brush. Therefore, when using a tap to clean brushes, water waste is greatly limited and reduced.

[0040] d) Through the drainage of the pipe, the wastewater after cleaning the brush tip flows from the bottom of the pipe to the bottom of the sink, avoiding splashing and contamination of the sink walls, countertop, and clothes. During the brush cleaning process, the high-concentration wastewater first flows into the sink drain pipe, and the bottom of the sink is continuously rinsed by the wastewater with decreasing concentration until clean water flows out of the pipe. After the brush is cleaned, the bottom of the sink is also basically cleaned, and there is no need to clean the sink walls and countertop again.

[0041] e) In one embodiment, a cleaning section with flexible walls, made of a flexible material, is incorporated into the pipe, allowing for hand squeezing. As the brush tip is rinsed by the water flow within the pipe, the brush waist can be gently squeezed, allowing the ink or pigment within the bristles to be carried away by the water more quickly. During the brush cleaning process, fingers no longer need to contact the brush tip. This avoids ink residue remaining under fingernails, which increases cleaning difficulty and water consumption.

[0042] f) The brush care device of this invention can also be used as a portable brush box, replacing commonly used tools in calligraphy and painting such as brush holders, brush containers, and brush boxes. The brush is placed inside the pipe, and the brush is easily secured inside by utilizing the friction between the brush and the inner wall of the pipe (when the pipe is flat), or by connecting the brush to the pipe using a hanging rope on the brush handle, or by using an elastic clip to hold the flexible pipe. Both ends of the pipe are open, ensuring breathability for the brush stored inside. Simultaneously, the temperature and humidity inside the pipe are more constant than outside, thus protecting the brush.

[0043] g) The invention has been verified by the inventors over several months of use, and the cleaning effect of the invention on brushes is excellent. Attached Figure Description

[0071] The following description, in conjunction with the accompanying drawings and specific embodiments, will be provided.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0073] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0074] Example 1

[0075] In a basic embodiment of the brush care device of the present invention, see [reference needed]. Figures 1 to 9 The brush care device 100 of the present invention includes a pipe for inserting a brush 300. When the brush 300 is inserted into the pipe, the bottom of the pipe is facing upwards and the tip of the brush is inserted into the bottom of the pipe. Under the action of gravity, the brush falls freely and the tip of the brush is caught at the upper end of the pipe. The brush 300 is fixed by hand and water is injected into the pipe to clean the brush.

[0076] After the brush 300 is inserted into the pipe, a gap remains between the inner wall of the pipe and the brush 300. (See attached image.) Figure 9 Both the pipe and the brush 300 have circular horizontal cross-sections, with gaps forming either perfect or eccentric annular rings. Water injected into the pipe passes through these annular gaps and flows from the ferrule towards the brush head 320. The water volume must take into account the maximum flow rate of these gaps. Without pressure, the water flows freely within the pipe, carrying away ink or pigment from the outer bristles in a 360° circle. Due to adhesion to the wall, some of the outer bristles separate from the inner bristles, with the ink or pigment on the inner bristles being carried away by the water. As the water continues to flow, the ink or pigment on the core bristles is gradually diluted and carried away. Without external force, the self-cleaning time through the flowing water is relatively long.

[0077] Example 2

[0078] To further improve the cleaning efficiency of the brush tip, in a further embodiment of the brush care device of the present invention, see [link to further embodiment]. Figures 1 to 9Based on Embodiment 1, the pipe is provided with a cleaning section 130 with a flexible wall. The flexible wall facilitates gentle squeezing of the brush waist from different directions during the cleaning process of the brush head 320, so that the ink or pigment on the secondary hairs and core hairs can be washed away more quickly. Gentle squeezing also helps to wash away the ink or pigment near the base of the brush, as the accumulation of ink or pigment near the base of the brush will harden that area and cause the brush to not hold its tip.

[0079] The length of the cleaning section 130 is greater than the length of the brush tip 320, and the brush tip 320 is rinsed in the cleaning section 130. The inner diameter of the cleaning section 130 is 0.1-3 cm larger than the diameter of the brush holder, preferably 0.1-1 cm larger, including but not limited to diameter differences of 0.1, 0.2, 0.3, 0.5, 0.7, and 1 cm. The wall thickness of the cleaning section 130 is 0.5-3 mm, preferably 1-2 mm, such as 1 mm, 1.5 mm, or 2 mm. The thicker the wall, the more effort is required to squeeze the brush waist through the wall, but as a protective tube for the brush, the thicker the wall, the stronger the support and the better the anti-squeezing effect on the brush.

[0080] The cleaning section 130 is made of a flexible material. Preferably, a rubber with a high elastic modulus is selected, especially any transparent or semi-transparent rubber selected from silicone, polyurethane rubber, butadiene silicone rubber, vinyl rubber, butyl rubber, nitrile rubber, neoprene rubber, acrylic rubber, and acrylonitrile rubber. Of course, a completely opaque rubber material can also be selected. Using transparent rubber makes it easier to observe the cleaning status of the pen tip 320 at any time.

[0081] Example 3

[0082] Based on the structural foundation of the cleaning section 130 with flexible pipe wall in Embodiment 2, this embodiment further specifies the pipe structure. The pipe is configured from top to bottom as four pipe sections: water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140.

[0083] Water inlet section 110 is a pipe section that facilitates the filling of water into the pipeline. Increasing the water inlet area of ​​water inlet section 110 is an important technical direction. If the inlet is too small, the minimum water inlet area is the cross-sectional area of ​​the inner diameter of the pipe minus the cross-sectional area of ​​the pen tube. If the pipe diameter is small, care must be taken when filling the pipe, as water can easily leak outside the pipe. Cutting the top of the pipe at an angle is one way to increase the water inlet area. The angled cut creates an elliptical cut, the area of ​​which is larger than the pipe diameter. Recommended, see [link to relevant documentation]. Figure 1 , Figures 4 to 9 The water receiving section 110 is constructed as an open funnel, particularly a side-open funnel, the shape of which can be variable or fixed; it is recommended to set it as a side-open funnel with a variable shape.

[0084] In this embodiment, the variable-shaped side-opening funnel is formed by setting a longitudinal slit 101 on the rubber tube. The longitudinal slit 101 is a slit set along a generatrix of the pipe, starting from the top of the pipe and extending to the interface between the water receiving section 110 and the water storage section 120.

[0085] In a preferred embodiment, see Figure 1 , Figures 4-6 The stress concentration at the bottom end of the longitudinal seam 101 during repeated opening can lead to crack propagation. Therefore, a crack-stopping part 102 is provided at the bottom end of the longitudinal seam 101. Preferably, the crack-stopping part 102 is a crack-stopping hole. More preferably, the crack-stopping hole is a circular hole, an elliptical hole, or a slot.

[0086] The water receiving section 110 is a pipe section with a longitudinal slit 101 when there is no external force, and deforms into a side-opening funnel with the longitudinal slit 101 open when there is an external force. That is, in this embodiment, without adding any additional parts, a side-opening funnel with a large water receiving area is obtained by modifying the rubber tube based on its own characteristics.

[0087] It is easy to separate the longitudinal seam 101 to obtain a side-opening funnel, but to maintain the shape of the side-opening funnel during the brush washing process, further structural improvements to the water section 110 are required. This embodiment provides two solutions, A and B, for stabilizing the side-opening funnel:

[0088] A. The water receiving section 110 is provided with an annular folding part 112 and a stabilizing part 111, with the stabilizing part 111 located at the uppermost end of the pipe.

[0089] Specifically, see Figure 6 The folded portion 112 is a groove provided on the inner wall of the water receiving section 110. Alternatively, the groove can be provided on the outer wall, or both the inner and outer walls can be provided simultaneously, or an annular slit can be provided on the inner wall. This allows the water receiving section 110 to partially form an annular thin-walled section, making it easier for the stabilizing portion 111 to fold outwards from the pipe wall. The folded stabilizing portion 111 then keeps the longitudinal slit 101 of the water receiving section 110 in an open state. Preferably, the thickness of the folded portion 112 is any proportion between 30% and 80% of the pipe wall thickness of the water receiving section 110. When providing the folded portion 112, it is necessary to ensure that the folded portion 112 itself does not tear during repeated folding.

[0090] In one embodiment, to make the edges of the longitudinal slit 101 curl up, forming a higher sidewall of the side-opening funnel, the water flow into the pipe is improved. See [reference needed]. Figure 6 The corner symmetrical cut-off portion 114 is cut off on both sides of the longitudinal seam 101 near the stable portion 111. Figure 6In the design, the cut-off portion 114 is triangular, and the remaining edge of the stabilizing portion 111 is a straight line. Depending on the shape of the cut-off portion 114, the remaining edge of the stabilizing portion 111 can also be an arc, a parabola, an ellipse, or two straight lines connecting rounded corners. The folded stabilizing portion 111 has a reverse stretching effect on the remaining part of the water receiving section 110 connected to it. The cut-off portion 114 is used to stretch and disconnect a portion of the pipe wall in the water receiving section 110 from the stabilizing portion 111, maintaining the arc shape of that portion of the pipe wall and forming the higher sidewall of the side-opening funnel.

[0091] To facilitate maintaining the folded state of the stabilizing part 111 and to facilitate hanging the care device 100 on the pen holder, a through hole 113 is provided on the stabilizing part 111, with the center of the through hole 113 located on the symmetrical plane of the stabilizing part 111. A pull cord or pull ring can be installed on the through hole 113. When washing the pen, fixing the pull cord or pull ring will prevent the stabilizing part 111 from springing back.

[0092] When cleaning the calligraphy brush, the side-opening funnel on the care device 100 is in the open state, that is... Figure 5 , Figure 6 In the second state shown, when carrying or storing the brush, the side-opening funnel on the care device 100 is in the closed state, i.e. Figure 4 The first state is shown.

[0093] B. The water receiving section 110 is only provided with a stabilizing part 111, which is located at the uppermost end of the pipe.

[0094] Specifically, in one implementation, see [link to implementation details]. Figure 7 A stabilizing plate 1111 is installed at the top of the stabilizing part 111.

[0095] The stabilizing plate 1111 can be detachably installed on the top of the stabilizing part 111. For example, the stabilizing plate 1111 uses a clamping plate. The pipe wall of the water receiving section 110 of the clamping plate part will not bend, while the pipe wall of the unclamped part bends, forming a higher side wall of the side-opening funnel. Figure 7 The computer-generated drawing shown does not depict the effect of the natural bending of the pipe wall in the unclamped portion.

[0096] The stabilizing plate 1111 can also be fixedly installed on the top of the stabilizing part 111. For example, a rigid plate can be directly pasted on the inner or outer side of the stabilizing part 111. It is preferable to paste a rigid plate on the outer side of the stabilizing part 111.

[0097] In one implementation, see Figure 7 The stabilizing plate 1111 is provided with a pen clip 200 for holding the pen tube 310.

[0098] In one embodiment, the water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140 are integrated into one unit. The water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140 are all made of the same material, that is, the pipeline is divided into the aforementioned four sections entirely according to functional areas.

[0099] In one parallel embodiment, the water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140 are partially or entirely configured as detachable pipe sections. See also Figure 8 The water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140 are all configured as detachable pipe sections. In the segmented configuration, the cleaning section 130 must be a flexible pipe section. The water receiving section 110, water storage section 120, and drainage section 140 can be either flexible pipe sections or pipe sections made of rigid materials, and can be configured separately or as a single unit depending on the material characteristics. For example, the cleaning section 130 and drainage section 140 can both use flexible pipe sections, and these two sections can be configured as a single unit; the water receiving section 110 and water storage section 120 can use rigid material pipe sections, and these two sections can be integrally formed. When the water receiving section 110 is made of rigid material, the side-opening funnel is fixed.

[0100] In a preferred embodiment, the total length of the water receiving section 110, water storage section 120, cleaning section 130, and drainage section 140 is greater than the length of the brush 300, making it easy to carry and store the brush 300 completely hidden in the pipe; the total length of the water storage section 120, cleaning section 130, and drainage section 140 is less than the length of the brush 300, making it easy to control the brush tube at the water receiving section 110 when cleaning the brush 300, preventing the brush 300 from being washed away by the flowing water. When cleaning the brush, once the tip of the brush reaches the water receiving section 110 and appears in the open funnel on the side, the hanging rope on the top of the brush can be pulled to place the brush head 320 in the cleaning section 130. One hand holds the brush tube and the pipe (preferably the water receiving section 110) together and secures them, while the other hand continuously adjusts the direction and gently squeezes the brush head 320 in the cleaning section 130 until the water drained from the drainage section 140 is clean, at which point the brush washing stops.

[0101] The water storage section 120 is a designation used for ease of description. Some calligraphy brushes have a significantly larger ferrule diameter, making it possible for the tube section above the ferrule to store water. When the water injection speed is faster than the gap flow rate, water can be stored in the water storage section 120, reaching the bottom of the longitudinal joint. Adjusting the water injection speed to equal the gap flow rate maintains the water level in the water storage section 120, filling the gap with water and facilitating full-circumference cleaning of the brush tip. When the ferrule diameter of the calligraphy brush is the same as the brush tube diameter, to retain water in the water storage section 120, the lower end of the drain section 140 or the cleaning section 130 should be pinched to control the draining speed.

[0102] When using the care device 100 to clean a calligraphy brush in a regular handwashing sink, the bottom of the drain section 140 contacts the bottom of the sink, so the wastewater generated from cleaning the brush will not splash and will flow directly into the drain hole of the sink.
