Description

TECHNICAL FIELD

[0001] The present invention relates to a liquid absorbing device for collecting or absorbing moisture produced in the wall of a brass instrument during playing. BACKGROUND

[0002] A brass instrument such as a trumpet, horn, euphonium, tenor horn, trombone or tuba is played by a player blowing into a mouthpiece. During use, saliva and moisture from the exhaled air accumulates in the air conduit. The accumulation of saliva and moisture (hereinafter referred to as saliva, etc.) in the air conduit during use can affect the playing. The saliva and exhaled moisture (hereinafter referred to as saliva, etc.) accumulated in the air conduit during use must be regularly discharged from the air conduit, otherwise the playing can be affected. Therefore, the tube of the brass instrument is provided with holes for discharging saliva, etc. in advance, and these holes are blocked with a water key. Therefore, the player must regularly open the water key to discharge the saliva, etc. in the tube through the discharge hole.

[0003] In practice, the water accumulated in the tube of the brass instrument during use is mostly exhaled water, and the amount of saliva is very small, so from a hygiene point of view, direct discharge onto the floor is not a problem. Therefore, the player usually lays a cloth or paper towel on the floor and then drips the moisture in the brass instrument onto the cloth or paper towel, but the audience listening to the performance cannot see the cloth or paper towel on the stage floor, so when the player finally drools, it looks as if the saliva is directly discharged onto the floor, giving a person an unpleasant and unpleasant impression. The situation is still the same. In addition, since the saliva is actually discharged during the performance interval, there is no time to carefully discharge it, and the discharged saliva often falls off from the cloth, etc. laid on the ground. When cleaning up after the performance, if the cloth, etc. is full of saliva, if these cloths, etc. belong to others, especially in the time and space background of the prevalence of the COVID-19 virus infection, the player himself may not know whether he has any infectious disease, in addition to the work of cleaning up these cloths, etc. It is quite unpleasant, but it is also easier to directly or indirectly spread the virus.

[0057] The present application uses "about", "approximately", "close to", "substantially", or "essentially" and the like to include a range of deviation from the stated numerical value, characteristic, and range of deviation that can be understood by one skilled in the art. For example, the foregoing terms can mean a value within one or more standard deviations of the stated value (e.g., a value within ±20%, ±15%, ±10%, or ±5%), or a deviation that the characteristic practically encompasses (e.g., the statement "substantially parallel" can mean practically close to parallel rather than ideally perfect parallel). In addition, the acceptable deviation range can be selected according to the measurement properties or other properties, and not all numerical values or characteristics are applied with one deviation range.

[0058] The present application provides a liquid absorption device for a wind instrument to solve the problems caused by the situation described in the above background section. Please refer to Figure 1 and 2 The liquid absorption device mainly includes an adjustable carrier unit 20, which is used in combination with an external water absorption member A. In this description, the water absorption member A does not mean only a water absorption object, but refers to an object that can be used to absorb liquid, such as a sponge, a paper towel / towel, and the like, which is not particularly limited. In an embodiment of the present application, the adjustable carrier unit 20 can be used to connect to an external music stand 100. The music stand 100 is a simple schematic diagram in the present application, and the detailed part can refer to various stands on the relevant website, such as the picture display in the Baidu website https: / / baike.baidu.hk / item / %E8%AD%9C%E6%9E%B6 / 5640336. The stand generally includes a tripod at the bottom to support and balance, a rod body connected to the middle section (some stands have a telescopic rod body), and a platform at the upper half to place the music score. The adjustable carrier unit 20 of the present application is mainly used to connect and fix at the position of the rod body of the aforementioned stand. Figure 1 The music stand 100 mainly includes a stand 101 to place the music score, a rod body 102 connected to the stand, and a tripod 103 connected to the rod body 102 to support and balance.

Based on the consideration of the height of the player, the environment, and the player's own playing habits, the player can adjust the relative position of the base 21 where the water adsorption member A is placed by the aforementioned manual or electric driving manner, wherein the relative position can be the axial direction of the X-axis, Y-axis, Z-axis in the three-dimensional space and the turning angle θ. In this description, the Z-axis represents the extension direction of the aforementioned music stand rod (generally the axial direction perpendicular to the ground), the X-axis, Y-axis, and Z-axis are perpendicular to each other, and the turning angle θ is taken as the rotation axis of the Z-axis. Therefore, the base 21 can be adjusted by the player in the Z-axis direction (also referred to as height), and the turning angle θ is adjusted to make the base 21 located at different positions in the XY plane formed by the X-axis and Y-axis.

[0061] In an embodiment of the present application, when the music stand 100 is stably erected on the ground and assembled and fixed with the adjustable carrier unit 20, at least one of the following conditions A and B is satisfied:

[0063] B. The shortest horizontal distance D1 between the outermost edge of the base 21 and the rod 102 of the music stand 100 is less than the shortest horizontal distance D3 between the end of any foot 103 of the music stand 100 and the rod of the music stand 100 when the foot is maximally erected on the ground.

[0064] Please also refer to Figures 3-4 , the liquid absorption device of the present application further comprises a liquid absorption unit 10 in addition to the adjustable bearing unit 20 described above; wherein the groove structure 210 is designed based on the profile, size and function of the liquid absorption unit 10, please also refer to Figure 4 , the base 21 of the present application mainly comprises a groove structure 210 and a socket part 211, the groove structure 210 is used to accommodate the liquid absorption unit 10, the liquid absorption unit 10 is mainly a porous structure, the porous structure has a plurality of uniformly distributed micropores to form a capillary structure to form a water absorption material, the porous structure can be selected from diatomite, gypsum, pottery clay, clay, sand, cotton, agar, silt, slag, resin, nylon, polyacrylate (ASAP) or a combination thereof. In an embodiment of the present application, the main material component of the porous structure is diatomite, the weight percentage of diatomite in the porous structure can be between 20% and 90%. Preferably, the weight percentage of diatomite in the porous structure is at least 60% or more and its composition does not contain asbestos or formaldehyde.

[0065] Please refer to Figure 6 , the porous structure has a liquid absorption surface 110, the liquid absorption surface 110 is not limited to which side surface of the porous structure, for example: if the porous structure is a flat thin plate body and has two opposite side surfaces, the liquid absorption surface 110 can be one of the middle side surfaces, or both opposite side surfaces can be the liquid absorption surface 110; wherein the liquid absorption surface 110 can be provided with a concave-convex structure 120, the concave-convex structure 120 can include one or more parallel or non-parallel straight or non-straight grooves, grooves with one or more bends, one or more closed ring-shaped grooves, chessboard arranged rectangular grooves, or a plurality of circular or elliptical grooves arranged in an array, etc. Any one or more combinations of the foregoing are not limited, the most important function is to improve the overall absorption efficiency and dissipation efficiency. In this embodiment, the concave-convex structure 120 is a plurality of parallel straight grooves, although the number of grooves shown in the icon is 4, but not limited thereto, the specific number is considered according to the actual situation.

[0066] In another embodiment of the present application, the profile of the grooves or recesses of the concave-convex structure 120 can be U-shaped, concave-shaped, V-shaped, trapezoidal, etc., without being limited thereto. Furthermore, the depth of the grooves or recesses of the concave-convex structure 120 can be 5% to 30%, preferably 10% to 20%, of the thickness of the plate of the porous structure, so as to improve the overall absorption efficiency and dissipation efficiency while maintaining the overall structural strength of the porous structure.

[0067] Please refer back to Figures 2-4 , the base 21 is provided with one or more ribs 213 and one or more through holes 214 on the bottom surface of the groove structure 210. The ribs 213 include a plurality of first ribs 213a and a plurality of second ribs 213b, which are arranged in a cross pattern and extend from one inner wall surface of the groove structure 210 to the opposite inner wall surface. In this embodiment, the groove structure 210 has a substantially parallelogram profile with arc-shaped corners at each corner, and the first ribs 213a and the second ribs 213b extend straight from the inner wall surfaces on different sides to the opposite inner wall surfaces, thereby forming a checkerboard structure with perpendicular intersections. In addition, the through holes 214 are arranged in each square of the checkerboard structure formed by the first ribs 213a and the second ribs 213b. It is noted that the arrangement of the ribs 213 is not limited to this, and is mainly used to strengthen the structural strength of the entire base 21, so that the liquid absorption unit 10 and the bottom surface of the groove structure 210 are not in direct contact and maintain a certain degree of gap, and the through holes 214 are arranged in the rectangular grid of the checkerboard structure formed by the perpendicular intersections of the first ribs 213a and the second ribs 213b.

[0068] In addition, the base 21 is provided with a set of interfaces 211, and the adjusting member 22 is provided with a matching part 223. The base 21 and the adjusting member 22 are connected to each other through the set of interfaces 211 and the matching part 223. The above description shows that the base 21 and the adjusting member 22 are connected to each other through the specific disassembly mode. In this embodiment, the specific disassembly mode is a mutual embedding structure. Specifically, the set of interfaces 211 of the base 21 is a protrusion extending from the outer periphery of the base 21 adjacent to the middle region in a direction away from the groove structure 210, and the matching part 223 of the adjusting member 22 is a hollow structure provided at one end of the adjusting member 22. The base 21 is embedded in the hollow structure of the adjusting member 22 to be connected to each other in a mutual embedding mode. The protrusion can be in a plate shape, a cylindrical shape, or a square column shape, which is not limited herein. The profile of the hollow structure is determined according to the structure of the protrusion. The length of the protrusion is greater than or equal to the depth of the hollow structure, and the gap between the protrusion and the hollow structure is a clearance fit. The maximum gap between the protrusion embedded in the hollow structure is not greater than 5 mm. Preferably, the maximum gap between the protrusion embedded in the hollow structure is between 1 mm and 3 mm.

[0069] In another embodiment of the present application, the base 21 is further provided with a removal structure for separating the water absorbing member (not shown) or part or all of the liquid absorbing unit 10 from at least one side surface of the base 21 after being arranged. The removal structure is mainly used for easily removing the liquid absorbing unit 10, such as a porous structure containing diatomaceous earth, arranged in the groove structure 210. Since the porous structure containing diatomaceous earth is arranged in the groove structure 210, the thickness of the porous structure is basically less than or equal to the depth of the groove structure, and the overall area of the porous structure is basically close to the opening area of the groove structure. Therefore, the porous structure is not easy to remove due to the small gap between the porous structure and the inner wall of the groove structure 210.

[0070] The dismounting structure can include a pushing member 212 and a through hole 214 formed in one of the bases 21. The pushing member 212 has a main rod portion 212a and cap portions 212b at both ends of the main rod portion 212a. The cross section of the pushing member 212 is substantially I-shaped, so that the pushing member 212 can be inserted into the through hole 214 and limited in the through hole 214. The cap portions 212b can have the same shape as the through hole 214 or different shape, which is not limited herein. In this embodiment, the cross section of the main rod portion 212a and the cap portions 212b and the through hole 214 are circular. The diameter of the cap portions 212b is greater than that of the through hole 214, so that the pushing member 212 can be inserted into the through hole 214 and limited in the through hole 214. In addition, the length of the pushing member 212 is determined according to the depth of the groove structure 210, so that the porous structure is pushed upward by the pushing member 212 and exposed outside the groove structure 210 for easy removal by the user.

[0071] Please refer to Figure 7 In another embodiment of the present application, the dismounting structure can be an open gate 200 formed on the base 21. The open gate 200 is a recess formed by recessing a part of the top surface of the inner wall of at least one side of the groove structure 210. The part not recessed can be used as a limit for the porous structure, so that the user can easily remove the porous structure through the open gate 200.

[0072] Please refer to Figure 1 and Figures 5A-5B , Figures 5A-5B The adjustment member of the present application is shown in the perspective view and the action state view. The adjustment member 22 can be connected or separated from the rod of the music stand by a mechanical structure or a magnetic structure. In this embodiment, the adjustment member 22 is connected or separated from the rod of the music stand by a mechanical structure. The mechanical structure mainly includes a body portion 221, a locking portion 222 and a matching portion 223. The two ends of the body portion 221 are formed with two corresponding recessed ends 221a. The two recessed ends 221a are not in contact with each other and maintain a certain distance. The profile of the body portion 221 is approximately C-shaped or C-like. In addition, the inner side of the body portion 221 is provided with a sliding rail 2211. The inner profile of the body portion 221 corresponding to the side direction of the matching portion 223 has a first arc surface (arc 1). The body portion 221 is provided with a screw hole (not shown) corresponding to the other side of the matching portion 223.

[0073] Presented above, the locking part 222 includes a screw member 222a, a gripping member 222b, and a clamping member 222c. The gripping member 222b and the clamping member 222c are respectively disposed at both ends of the screw member 222a, and the screw member 222a passes through the screw hole of the body part 221. In addition, the clamping member 222c is located in the inner perimeter region of the body part 221, and the clamping member 222c has a second arc surface arc2 corresponding to the first arc surface arc1 of the body part 221. Furthermore, the clamping member 222c can cooperate with the slide rail 2211 of the body part 221, so that the clamping member 222c can be freely displaced on the slide rail 2211 by external force. To further explain, the radii of curvature of the first arc surface arc1 and the second arc surface arc2 are determined according to the size (or diameter) of the rod 102 of the music score holder 100, so that the gripping member drives the screw member 222a to rotate by an external force, thereby changing the distance between the second arc surface arc2 of the clamping member 222c and the first arc surface arc1 of the body part 221, so as to clamp and fix the base 21 on the rod 102 of the music score holder 100.

[0074] Please return Figures 3-4 According to another embodiment of the present invention, the base 21 is further provided with a tolerance compensation structure 230, the tolerance compensation structure 230 being used to ensure that the liquid absorption unit 10 disposed in the groove structure 210 satisfies at least one of the following conditions C to F under a specific state:

[0075] C. When the liquid absorption unit 10 is a polygonal plate structure, at least one side surface of the outer periphery of the liquid absorption unit 10 is completely in contact with the inner wall surface of the groove structure 210.

[0076] D. When the liquid absorption unit 10 is a circular or elliptical plate structure, a specific proportion of the outer peripheral surface of the liquid absorption unit 10 abuts against the inner wall surface of the groove structure 210, wherein the specific proportion is greater than or equal to 50%.

[0077] E. When the liquid absorption surface 110 of the liquid absorption unit 10 and the plane formed by the X-axis and Y-axis are at a positive angle or a negative angle greater than 90 degrees, the liquid absorption unit 10 will not be partially or completely separated from the groove structure 210 due to its own gravity.

[0078] F. When the positive or negative angle between the liquid absorbing surface 110 of the liquid absorbing unit 10 and the plane formed by the X-axis and Y-axis is greater than 90 degrees, the liquid absorbing unit 10 will not be completely separated from the groove structure 210 by other external forces.

[0079] In the above, the specific state refers to the state in which the music stand 100 is stably erected on the ground, is fixedly connected with the adjustable bearing unit 20, and the liquid absorbing surface 110 faces away from the ground. In the present embodiment, the tolerance compensation structure 230 is a spring sheet with a bend adjacent to the adjusting member 22 and arranged on the inner wall surface of the groove structure 210. The bottom side of the spring sheet is provided with a fixed protrusion (not shown) for being fixedly connected with the first rib 213a adjacent to the spring sheet. Further, because the liquid absorbing unit 10 may have a certain error from the default size during manufacturing, the liquid absorbing unit 10 may be loose and displaced due to the tolerance when installed in the groove structure 210. Therefore, when the liquid absorbing unit 10 is installed, the spring sheet with a bend can abut against the side surface of the liquid absorbing unit 10 and apply appropriate external force, so as to satisfy one or more of the above conditions C-F.

[0080] In summary, the liquid absorbing device based on a wind instrument can timely process the saliva accumulated on the instrument during blowing and leave no trace under different conditions such as self-practice, public performance, or various teaching and communication occasions. In addition, the liquid absorbing device is also light and portable for the user during movement in the above different occasions.

[0081] The present application is described in detail with some embodiments, but other embodiments can also be feasible, and therefore the description of the embodiments of the present application should not limit the scope and spirit of the appended claims.

[0082] For those skilled in the art, the present application can be modified and changed without departing from the scope and spirit of the present application. The present application covers these modifications and changes as long as they are within the scope and spirit of the appended claims.
