Description

Technical Field

[0001] The present invention relates to the technical field of piano key cleaning, and in particular to an integrated mechanical tool for cleaning and maintaining piano keys. Background Art

[0002] The piano is composed of keys (including white keys and black keys) and a metal string soundboard. It is one of the instruments with the widest range of sound. During the long-term use of the piano, a lot of dust and stains will remain on the surface of the keys and in the gaps between the keys. The accumulation of dust and stains will affect the tone of the piano, so the keys need to be cleaned regularly.

[0003] There are some existing technologies that can clean and maintain the surface of piano keys and the gaps between keys. For example, the patent publication number is CN108543762B. Its main technical means is to squeeze two gripping rings towards each other, and two limit blocks squeeze the sponge column, immerse the compressed sponge column in a mixture of detergent and water, and pull it out after it is wet, and fit the sponge column on the upper surface and the front end wall of the white key and slide it back and forth until the detergent mixture is evenly attached to the upper surface and the front end wall of the white key, and then put the surface scraper on the key surface and move along the key surface, and use the conical shovel to separate the dirt from the key surface. After analysis, the disadvantages of this technical solution are : Before each cleaning, the sponge needs to be taken away from the key surface and soaked in cleaning liquid, which is inconvenient to use and cannot be automatically aligned with the key surface and the gaps between the keys. In addition, the black keys on the white keys of the piano are unevenly distributed, and the distribution of the gaps between the keys is also uneven. When cleaning the key surface, the cleaning method of the key gaps cannot be adaptively adjusted automatically. Each key surface and each gap between the keys need to be adjusted and cleaned separately, which greatly prolongs the cleaning time and reduces the efficiency of piano key cleaning and maintenance. Based on this, the present invention provides an integrated mechanical tool for cleaning and maintaining piano keys with a simple and ingenious structure, which can automatically soak the sponge in cleaning liquid before each cleaning and automatically adjust the cleaning method according to different key surfaces and gaps between the keys.

When the connecting block moves until the wedge block contacts the black key, relative sliding occurs between the wedge block and the side wall of the black key, and the wedge block moves in the direction close to the telescopic member, driving the mounting block and the end sponge to move synchronously, then the telescopic member and the middle sponge are both contracted. During this process, when the wedge block begins to translate, the cleaning rod is still in the gap between the white keys, then the movable block flips in the direction away from the white key until the cleaning rod slides into the transverse gap between the white key and the black key. As the connecting block continues to move, the cleaning rod can clean the transverse gap between the white key and the black key, and the movable block gradually resets until the cleaning rod slides into the longitudinal gap between the white key and the black key. At this time, the movable block is completely reset, and the cleaning rod can clean the longitudinal gap between the white key and the black key. In this way, adaptive adjustment can be achieved for the gaps between keys of different shapes, so as to automatically clean the gaps between keys of different shapes and improve practicality.

[0022] In actual application of this embodiment, in the initial state, the shell 1 is placed above the keys, and its two ends are respectively in contact with the piano board on both sides of the keys, and the end sponge 2 is located above the connecting block 3. Figure 3As shown, at this time, the end sponge 2 and the middle sponge 4 both contact and squeeze the soaked sponge 11, and the surfaces of the end sponge 2 and the middle sponge 4 in contact with the white keys squeeze the soaked sponge 11, and the end sponge 2 and the middle sponge 4 will absorb the cleaning liquid in the soaked sponge 11; the transmission component 10 drives the connecting block 3 to flip downward, and the connecting block 3 rotates to the end sponge 2 and is located below it. At this time, the end sponge 2 and the middle sponge 4 both contact the top surface of the white key, and then push the connecting block 3 to slide on the top surface of the white key, and the end sponge 2 and the middle sponge 4 can clean the top surface of the white key. In this process, the gap component 9 can move synchronously and clean the gaps between the white keys; when the connecting block 3 moves to the wedge block 5 and contacts the black key, relative sliding occurs between the wedge block 5 and the side wall of the black key, and the wedge block 5 moves in the direction close to the telescopic member 7, driving the mounting block 6 and the end sponge 2 to move synchronously, then the telescopic member 7 and the middle sponge 4 both shrink, and the middle sponge 4 can squeeze out the remaining cleaning liquid therein after shrinking. After the telescopic member 7 shrinks, the cleaning block 8 stretches, and the cleaning The cleaning block 8 contacts the top surface of the black key; then the connecting block 3 continues to move, and the middle sponge 4 and the end sponge 2 can clean the top surface area of the white key near the black key, and the stretched cleaning block 8 can clean the top surface of the black key, and the gap component 9 moves with the end sponge 2 and cleans the gap between the black key and the white key; in this way, it can be ensured that the cleaning sponge is automatically soaked in cleaning liquid before cleaning, and a small amount of soaking will not drip cleaning liquid to cause damage to the piano, and the top surface of the white key is cleaned from the end of the white key away from the black key to the direction close to the black key, and when contacting the black key, the position of the end sponge 2 and the shape of the cleaning block 8 are automatically adjusted according to the shape of the black key, and the specific shape of the white key top surface can be followed for targeted cleaning and maintenance, and the cleaning method can be adaptively adjusted when there are black keys. When cleaning the remaining area of the white key top surface, the black key can be cleaned synchronously, and the gap component 9 moves with the end sponge 2 and can adapt to the gaps between keys of different shapes, so that all keys and the gaps between keys can be cleaned and maintained at one time, which is easy to use and improves the efficiency of cleaning and maintenance.

[0023] The surface of the wedge block 5 is provided with a dust-repellent layer, which can clean the side walls of the black keys.

[0024] like Figures 1-11 As shown, as a preferred embodiment of the present invention, the output end of the transmission assembly 10 is connected to the connecting block 3 by a connecting rod 14, and the connecting rod 14 is an elastic telescopic structure, a transmission block 15 is fixed on the connecting block 3, and a sliding rod 16 is slidably installed on the side wall of the shell 1 and passes through it, and a hand-held block 17 is fixed to the end of the sliding rod 16 located on the outside of the shell 1; when the transmission assembly 10 drives the connecting block 3 to rotate to the end sponge 2 located below it, the transmission block 15 is aligned with the sliding rod 16, and the sliding rod 16 is pushed toward the shell 1 through the hand-held block 17, then the connecting rod 14 is stretched, and the end sponge 2 and the middle sponge 4 slide on the top surface of the white key toward the black key.

[0025] In one case of this embodiment, when the end sponge 2 is located above the connecting block 3, the transmission block 15 is located between the end sponge 2 and the black key. When the transmission assembly 10 drives the connecting block 3 to rotate to the bottom of the end sponge 2, the connecting block 3 is located between the transmission block 15 and the black key. The elastic telescopic structure is a structure formed by nesting multi-stage pipe fittings with built-in springs. In actual application, a gear rack and electric telescopic rod structure can also be used. This embodiment does not make specific limitations here.

[0026] It should be noted that, during the flipping process of the connecting block 3 , the connecting rod 14 is in a free state. When a thrust is applied through the hand-held block 17 , the magnitude of the thrust is sufficient to stretch the connecting rod 14 .

[0027] In actual application of this embodiment, in the initial state, the hand-held block 17 is located at the end away from the shell 1 on its moving path; when the transmission assembly 10 drives the connecting block 3 to rotate to the end sponge 2 located below it, the transmission block 15 is aligned with the sliding rod 16, and the hand-held block 17 is held to push the sliding rod 16 toward the shell 1, then the connecting rod 14 is stretched, and the end sponge 2 and the middle sponge 4 slide on the top surface of the white key toward the black key, so that the top surface of the white key can be cleaned and maintained.

[0028] like Figure 2-Figure 11 As shown, as a preferred embodiment of the present invention, a drying cloth 13 is provided on the side of the telescopic member 7 close to the transmission block 15, and when the end sponge 2 is located above the connecting block 3, the drying cloth 13 is located between the end sponge 2 and the black key; when the transmission assembly 10 drives the connecting block 3 to rotate until the end sponge 2 is located below it, the drying cloth 13 contacts the top surface of the white key, and the end sponge 2 is located between the drying cloth 13 and the black key.

[0029] In actual use of this embodiment, the top surface area of the white keys where the end sponges 2 and the middle sponges 4 contact will contact the drying cloth 13, which can wipe off the cleaning liquid in time to keep the keys dry after cleaning, and avoid moisture causing expansion of the wood or rust of metal parts.

[0030] like Figure 2-Figure 5 As shown, as a preferred embodiment of the present invention, the transmission assembly 10 includes: A first rotating shaft 1001 is rotatably mounted in the housing 1 and fixedly connected to an assembly block 1008. The assembly block 1008 is connected to a fixed end of the connecting rod 14, and a movable end of the connecting rod 14 is connected to the connecting block 3. A second rotating shaft 1002 is rotatably mounted in the housing 1 and rotates synchronously with the first rotating shaft 1001 , and a gear 1004 is coaxially fixedly mounted on the second rotating shaft 1002 ; and The lifting block 1006 is slidably mounted on the shell 1 and is connected to the shell 1 through an elastic member. A rack 1005 is fixed to the bottom of the lifting block 1006, and the rack 1005 is engaged with the gear 1004. The lifting block 1006 is arranged through the top plate of the shell 1, and a pressing handle 1007 is fixed to the top end outside the shell 1.

[0031] In one case of this embodiment, the assembly block 1008 is the output end of the transmission component 10, and the number of the assembly blocks 1008 is multiple, and the multiple assembly blocks 1008 correspond one-to-one to multiple white keys respectively. The first rotating shaft 1001 is fixedly connected to the multiple assembly blocks 1008; the first rotating shaft 1001 and the second rotating shaft 1002 are connected by a belt 1003. Of course, the two can also be connected by other structural components that can achieve synchronous rotation; the elastic member can be a spring, and can also be replaced by other elastic components, such as silicone columns, springs, etc., which are not specifically limited in this embodiment.

[0032] In actual application of this embodiment, in the initial state, the end sponge 2 is located above the connecting block 3. Figure 3 As shown, the rack 1005 is at the top of its moving path; hold the pressing handle 1007 and press it down, the lifting block 1006 descends and drives the rack 1005 to descend synchronously, so that Figure 3 Taking the direction shown as an example, when the gear 1004 rotates clockwise, the second shaft 1002 drives the first shaft 1001 to rotate clockwise synchronously, so that the connecting block 3 rotates until the end sponge 2 is located below it, and the end sponge 2 and the middle sponge 4 can contact the top surface of the white key.

[0033] It should be noted that, in actual use, the shell 1 is first placed above the keys, and its two ends are respectively in contact with the soundboards on both sides of the keys. This is the initial state, and then the transmission assembly 10 is used to rotate the connecting block 3 to the end sponge 2 located below it. In this embodiment, the pressing handle 1007 is grasped and pressed down, and then, while keeping the pressing handle 1007 pressed, the hand-held block 17 is grasped to push the sliding rod 16 toward the shell 1, thereby achieving cleaning and maintenance of the keys.

[0034] like Figure 2-Figure 11 As shown, as a preferred embodiment of the present invention, the gap component 9 includes a movable block 901, and a movable block 901 is rotatably installed on the opposite back surfaces of the two end sponges 2 on both sides of the middle sponge 4, and the movable block 901 is elastically connected to the end sponges 2. A cleaning rod is installed on the movable block 901, and the cleaning rod is made of elastic material.

[0035] In one case of this embodiment, a first rod group 903 and a second rod group 904 are respectively installed on the two movable blocks 901, the first rod group 903 includes a plurality of cleaning rods, and the second rod group 904 includes a plurality of cleaning rods, and the first rod group 903 and the second rod group 904 on the two opposite end sponges 2 above two adjacent white keys overlap, and the cleaning rods of the first rod group 903 and the cleaning rods of the second rod group 904 are staggered and are both located in the gap between the two white keys.

[0036] Among them, the movable block 901 and the end sponge 2 can be connected by a spring or a spring, which will not be described in detail here; one end of the movable block 901 is rotatably mounted on the end sponge 2 through the shaft 902, and as Figure 6 As shown, the shaft 902 is located below the inclined surface of the wedge block 5; the cleaning rod can be a sponge or a wiping cloth, which is not specifically limited in this embodiment.

[0037] It should be noted that the relative movement between the first rod group 903 and the second rod group 904 only occurs after the wedge block 5 contacts the side wall of the black key, and the first rod group 903 and the second rod group 904 can only translate toward each other or translate away from each other. In the initial state, multiple end sponges 2 are all located above the connecting block 3, and the first rod group 903 and the second rod group 904 between two adjacent white keys overlap, and the cleaning rods of the two are staggered. In the process of the transmission assembly 10 driving the connecting block 3 to flip, multiple end sponges 2 flip synchronously, and then multiple first rod groups 903 and the second rod group 904 remain in an overlapping state and flip synchronously, and are finally inserted into the gaps between the white keys.

[0038] In actual application of this embodiment, when the transmission assembly 10 drives the connecting block 3 to rotate until the end sponge 2 is located below it, the first rod group 903 and the second rod group 904 are both inserted into the gaps between the white keys. When the connecting block 3 moves until the wedge block 5 contacts the black key, relative sliding occurs between the wedge block 5 and the side wall of the black key, and the wedge block 5 moves toward the direction close to the telescopic member 7, driving the mounting block 6 and the end sponge 2 to move synchronously, so that the telescopic member 7 and the middle sponge 4 are both contracted. During this process, when the wedge block 5 starts to translate, the cleaning rod is still located in the gap between the white keys. The movable block 901 flips in the direction away from the white key until the cleaning rod slides into the horizontal gap between the white key and the black key. As the connecting block 3 continues to move, the cleaning rod can clean the horizontal gap between the white key and the black key, and the movable block 901 is gradually reset until the cleaning rod slides into the longitudinal gap between the white key and the black key. At this time, the movable block 901 is completely reset, and the cleaning rod can clean the longitudinal gap between the white key and the black key. In this way, adaptive adjustment can be achieved for the gaps between keys of different shapes, so as to automatically clean the gaps between keys of different shapes and improve practicality.

[0039] like Figure 6 As shown, as a preferred embodiment of the present invention, a dust-receiving layer is provided on the surface of the cleaning rod.

[0040] like Figure 1 As shown, as a preferred embodiment of the present invention, a hot air blower is provided in the shell 1, and air holes are provided on the shell 1; in actual application, the hot air blower can accelerate the drying of the surface of the keys and the gaps between the keys.

[0041] like Figure 2-Figure 5 As shown, as a preferred embodiment of the present invention, the connection block 3 and the multiple telescopic parts 7 are all detachably connected; in actual application, the connection block 3 and the multiple telescopic parts 7 can be connected by a snap-on connection method or an adhesive connection method, and no specific limitation is made here. As long as the connection block 3 and the multiple telescopic parts 7 can be detachable, the connection block 3 can be replaced, and then the overall replacement of cleaning parts such as the end sponge 2, the middle sponge 4, and the cleaning block 8 can be achieved to ensure the cleaning performance after multiple uses.

[0042] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, a plurality of support blocks 18 are slidably installed in the shell 1, and the convex edge of each white key is slidably engaged with a support block 18, and a rod body passing through the shell 1 is fixed on each of the support blocks 18, and the end of each rod body located outside the shell 1 is fixedly connected to the gripping block 19.

[0043] When this embodiment is actually used, first hold the holding block 19 and push it toward the white key, then the support block 18 will eventually abut the side wall of the white key, and the top of the support block 18 will abut the convex edge of the white key, and then the transmission assembly 10 will make the connecting block 3 rotate to the end sponge 2 located below it. The supporting block 18 can support the white key, avoid the end sponge 2 from flipping over and the subsequent movement process causing the white key to be pressed down, and ensure the cleanliness of the white key surface. Then, under the premise of maintaining the above state, push the connecting block 3 to move toward the black key, thereby achieving the cleaning and maintenance of the keys.

[0044] The working principle of the present invention: The above embodiment of the present invention provides an integrated mechanical tool for cleaning and maintaining piano keys, which drives the connecting block 3 to flip downward through the transmission component 10, and the connecting block 3 rotates to the end sponge 2 and is located below it. At this time, the end sponge 2 and the middle sponge 4 are in contact with the top surface of the white key, and then the connecting block 3 is pushed to slide on the top surface of the white key, and the end sponge 2 and the middle sponge 4 can clean the top surface of the white key. During this process, the gap component 9 can move synchronously and clean the gaps between the white keys; when the connecting block 3 moves to the wedge block 5 and contacts the black key, relative sliding occurs between the wedge block 5 and the side wall of the black key, and the wedge block 5 moves in the direction close to the telescopic part 7, driving the mounting block 6 and the end sponge 2 to move synchronously, then the telescopic part 7 and the middle sponge 4 are both contracted, and the middle sponge 4 can squeeze out the remaining cleaning liquid therein after contraction, and the cleaning block 8 is stretched after the telescopic part 7 is contracted, and the cleaning block 8 is in contact with the top surface of the black key; then the connecting block 3 continues to move, and the middle sponge 4 is in contact with the black key. The sponge 4 and the end sponge 2 can clean the top surface area of the white keys near the black keys, and the stretched cleaning block 8 can clean the top surface of the black keys. The gap component 9 moves with the end sponge 2 and cleans the gaps between the black keys and the white keys. In this way, it is possible to ensure that the cleaning sponge is automatically soaked in cleaning liquid before cleaning, and a small amount of soaking will not cause damage to the piano by dripping cleaning liquid. The top surface of the white key is cleaned from the end of the white key away from the black key to the direction close to the black key, and when contacting the black key, the position of the end sponge 2 and the shape of the cleaning block 8 are automatically adjusted according to the shape of the black key. It can carry out targeted cleaning and maintenance according to the specific shape of the top surface of the white key, and adaptively adjust the cleaning method when there are black keys. When cleaning the remaining area of the top surface of the white key, the black key can be cleaned synchronously, and the gap component 9 moves with the end sponge 2 and can adapt to the gaps between keys of different shapes, so that all keys and the gaps between keys can be cleaned and maintained at one time. It is easy to use and improves the efficiency of cleaning and maintenance.
