Description

Technical Field

[0001] This utility model relates to a thumb-sized antique brush, belonging to the field of antique brush technology. Background Technology

[0002] With the popularization of the culture of collecting and appreciating cultural artifacts, items such as walnuts and beaded bracelets, which possess both aesthetic and collectible value, have become widely popular. The core maintenance needs for these artifacts involve two aspects: first, cleaning. Because the surfaces of these artifacts often have varying depths of texture, daily handling only touches the raised areas, leaving the recessed areas prone to accumulating sebum, dust, and other dirt. Long-term accumulation of these deposits can affect the appearance, texture, and collectible value of the artifact, necessitating regular cleaning with a brush. Second, polishing and brushing. Continuous and even brushing helps form a uniform patina on the surface, enhancing its luster and feel, which is a crucial step in the maintenance of these artifacts. Therefore, the artifact brush has become a core tool for enthusiasts, and its performance directly affects the cleaning efficiency and maintenance effect.

[0003] Currently, the mainstream antique brushes on the market are mainly divided into two categories: one is the traditional manual antique brush, represented by boar bristle brushes and nano brushes, which adopts the traditional brush structure of "handle + brush surface". The handle is mostly made of hard materials such as wood or plastic, and the brush surface is fixed to one end of the handle; the other is the electric antique brush, which integrates components such as motors and batteries into the traditional brush surface, and achieves automatic cleaning by driving the brush surface to rotate through the motor. However, these existing technologies have many shortcomings in practical applications, as follows: Traditional manual brushes for collecting and playing with antiques typically have handles designed to be 5-10cm long to ensure stability, resulting in a large overall size that requires separate storage bags or backpacks, making them inconvenient to carry around. Electric brushes for collecting and playing with antiques, due to the integration of motors, rechargeable batteries, and other components, are not only larger in size but also heavier and dependent on power sources, making them unsuitable for the immediate cleaning and brushing needs in outdoor, commuting, and travel scenarios. This prevents users from promptly removing dirt from the surface of their collectibles or performing daily brushing.

[0004] Traditional manual brushes for collecting and playing with antique items require the use of both hands: one hand holds the item (such as a bracelet, which needs to be secured by wrapping around the finger), while the other hand grips the brush handle to control the direction of the brush surface. The operation process is complicated. Furthermore, the presence of the handle causes a delay in the "force transmission" between the brush surface and the hand. This is especially problematic when dealing with the fine lines of antique bracelets or the deep grooves of antique walnuts, as the brush surface cannot accurately reach into the grooves, easily resulting in "incomplete cleaning".

[0005] Existing brushes for collecting and appreciating antique items lack a suitable fit for the hand, especially the thumb, which is crucial for controlling direction during brushing. Traditional manual brushes rely on the gripping force of the hand to maintain stability, which can easily lead to finger muscle fatigue over time. Electric brushes rely on the friction of the palm enveloping the body, but vibrations from the machine can further weaken this stability. During dynamic operations such as brushing, the brush is prone to slipping relative to the hand, resulting in uneven brushing pressure and potentially causing the brush to accidentally fall, damaging the collectibles or the brush itself, posing a significant safety hazard. Utility Model Content

[0006] This utility model provides a thumb-sized calligraphy brush to solve the problems of poor portability, inability to meet the needs of maintenance anytime and anywhere, insufficient ease of operation, and poor stability when fixed to the hand in the existing technology.

[0007] This utility model provides a thumb-sized collectible brush, which includes a brush body with a fixing part for fixing. The brush body has a thumb groove and brush bristles. The thumb groove is located at the top of the brush body and includes a first arc surface, a second arc surface, and a first groove. The first arc surface and the first groove are respectively located at both ends of the first arc surface. The bottom of the brush body has a fixing groove that matches the brush bristles. The brush bristles are fixed inside the fixing groove and extend outward.

[0008] Preferably, the first arc surface is located at one end of the brush body and extends outward in an arc shape with an inward tapering design, and the first arc surface fits against the bottom of the thumb joint.

[0009] Preferably, the first groove fits snugly against the thumb pad.

[0010] Preferably, the first groove and the first arc surface are smoothly transitioned through the second arc surface.

[0011] Preferably, the fixing groove is provided with multiple bristles, which are linearly distributed inside the fixing groove, and the depth of the fixing groove is greater than half the length of the bristles.

[0012] Preferably, the depth of the fixing groove is greater than two-thirds of the bristle length.

[0013] Preferably, the brush body has a chamfered outline.

[0014] Preferably, the fixing part includes a hook and loop fastener and a fixing block. The bottom of the hook and loop fastener is fixedly connected to one side of the brush body, and the fixing block is located on the side of the brush body away from the hook and loop fastener. The fixing block is fixedly connected to the brush body.

[0015] Preferably, the top of the fixing block is provided with a through groove that matches the Velcro, and the Velcro passes through the fixing block through the through groove.

[0016] Preferably, the top of the hook and loop fastener is a hook surface, and the middle section of the hook and loop fastener has a fleece surface that matches the hook surface.

[0017] The beneficial effects of this utility model are: This utility model provides a thumb-sized antique brush, which, through its thumb groove design, allows the thumb to directly control the brush, simplifying the operation process and improving the brush's ability to precisely clean the textures of antique items, ensuring cleaning effectiveness. The thumb groove and fixing part achieve a stable fit between the brush and the thumb, preventing slippage and improving the brush's stability and safety. The thumb groove design conforms to ergonomic principles, with the first arc surface fitting against the bottom of the thumb joint, the first groove fitting against the thumb pad, and a smooth transition through the second arc surface, dispersing localized pressure on the thumb surface and preventing edge chafing. The pressure enhances the user experience and frees up the other hand when brushing the beads, allowing for longer brushing time. While handling the beads, the brush bristles can draw fresh sweat into the deeper surfaces, making the beads cleaner and more lubricated. The fixing part uses a Velcro design, which can be adjusted according to the size of the user's thumb, improving the brush's versatility and applicability. The bristles are fixed in the fixing groove at the bottom of the brush body, with only a small portion of the bristles protruding. The bristles are left with room to move near the edge, minimizing the drop height difference and bringing the beads as close to the thumb as possible, improving the brushing effect and experience.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model discloses a thumb-sized calligraphy brush, comprising a brush body 1, a matching fixing part 2 on the brush body 1, and thumb grooves 11 and bristles 12 at the upper and lower ends of the brush body 1, respectively. The thumb groove 11 is located at the top of the brush body 1 and includes a first arc surface 111, a second arc surface 112, and a first groove 113. The second arc surface 112 is concave. The first arc surface 111 and the first groove 113 are located at the two ends inside the second arc surface 112, respectively. The first arc surface 111 is located at one end of the brush body 1 and extends outward in an arc shape towards the inside. The brush body 1 has a tapered design, with the first arc surface 111 fitting against the bottom of the thumb joint, the first groove 113 fitting against the thumb pad, and the first groove 113 and the first arc surface 111 smoothly transitioning through the second arc surface 112. The bottom of the brush body 1 has a fixing groove corresponding to the bristles 12. There are multiple bristles 12, which are linearly distributed inside the fixing groove. The depth of the fixing groove is greater than half the length of the bristles 12, preferably two-thirds. There is a gap between the bristles 12 and the edge of the fixing groove. The outline of the brush body 1 has a chamfered design. The fixing part 2 includes a hook and loop fastener 21 and a fixing block 22. The bottom of the hook and loop fastener 21 is fixedly connected to one side of the brush body 1, and the fixing block 22 is fixedly connected to the other side of the top of the brush body 1. The top of the fixing block 22 is provided with a through groove, and the top of the hook and loop fastener 21 is provided with a through groove. The top of the hook and loop fastener 21 is a hook surface, and the middle section of the hook and loop fastener 21 is provided with a fleece surface that matches the hook surface. The hook and loop fastener 21 is fixed by the cooperation of the hook surface and the fleece surface.

[0025] In use, the user places their thumb into the thumb groove 11, with the thumb joint fitting against the first arc surface 111 and the thumb pad fitting against the first groove 113. The first arc surface 111 has an arc-shaped opening design, which facilitates thumb joint movement, fixing the joint position without restricting movement. The thumb pad is located in the first groove 113 to prevent slippage and cooperates with the fixing part 2 to keep the thumb fixed to the brush body 1. The second arc surface 112 smoothly transitions with the first arc surface 111 and the first groove 113 to distribute local pressure on the thumb surface and avoid edge pressure. The bottom of the Velcro 21 is fixedly connected to the brush body 1, and the top of the Velcro 21 wraps around the top of the brush body 1 to cover the thumb and passes through the fixing block 22 from top to bottom through the through groove. Then, the Velcro 21 folds upward along the outer wall of the fixing block 22. The top of the Velcro 21 is secured by the interplay between the hook and loop surfaces of the Velcro 21 and the middle section of the Velcro 21, thus ensuring the fixation between the thumb and the brush body 1. During the fixing process, the tightness of the Velcro 21 can be adjusted according to the size of the user's thumb through the interplay between the hook and loop surfaces. Multiple bristles 12 are located in the fixing groove at the bottom of the brush body 1. The depth of the fixing groove is greater than half, preferably two-thirds, of the length of the bristles 12. Only a small portion of the bristles 12 is exposed during use, leaving room for movement near the edge, minimizing height differences and allowing the brush to be as close to the thumb as possible, enhancing the brushing experience. This avoids the bristles 12 being too thick, which could cause a top-heavy effect and significantly reduce the brushing experience. The brush body 1 has a chamfered outline to prevent sharp edges from rubbing against the thumb, index finger, or other areas during use. A simple fixation with a strap to the thumb ensures the brush remains fixed during brushing.

[0026] Compared with the existing design, the first arc surface 111 is located at one end of the brush body 1 and extends outward in an arc shape with an inward opening design, which fits with the bottom of the thumb joint. This not only fixes the joint position, but also facilitates the movement of the thumb joint due to the arc opening, without restricting its flexibility. The first groove 113 fits with the thumb pad, which can prevent the thumb pad from slipping. During the brushing process, slippage of the thumb can cause the brush to become unstable, affecting the brushing effect and even causing the brush to slip from the hand. This application effectively solves this problem, enhancing the stability between the brush and the thumb. The smooth transition between the first groove 113 and the first arc surface 111 via the second arc surface 112 can disperse local pressure on the thumb surface, avoiding edge pressure and improving the user experience. Furthermore, the single-handed brushing motion, similar to the action of turning prayer beads, enhances the brushing experience and extends the brushing time. Single-handed brushing not only provides the experience of turning prayer beads but also achieves brushing and polishing in one step, freeing up the other hand. This allows users to brush while using their phones, drinking tea, watching TV, or reading, without interrupting the brushing process. While polishing the beads, the brush bristles can also draw fresh sweat into the deeper layers of the surface, making the beads more resistant to sweat. For a more thorough cleaning, during the fixing process, the top of the Velcro 21 wraps around the thumb from the top of the brush body 1 and passes through the through groove to the fixing block 22 from top to bottom. Then, it folds back upwards along the outer wall of the fixing block 22 and is fixed by the cooperation of the hook side and the napped side. The tightness of the Velcro 21 can be adjusted according to the size of the user's thumb, making the fixing method more flexible and meeting the needs of different users, thus improving the versatility of the brush. Multiple bristles 12 are located in the fixing groove at the bottom of the brush body 1, so that only a small part of the bristles 12 are exposed during use. The bristles 12 are left with room to move near the edge, minimizing the drop height difference and bringing the bracelet closer to the thumb, enhancing the brushing experience. This makes the brush more flexible and stable during the brushing process, improving the brushing effect.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
