Embodiment one.
White key 1 is cleaned using this cleaning device.According to the structure of white key 1, it is known that carrying out cleaning master to it
If being cleaned to the upper surface of white key 1, white key front bulkhead 3 and white key side wall 4.
The first step implements infiltration processing using infiltration mechanism to the upper surface of white key 1 and white key front bulkhead 3.First, with big
Thumb and index finger are each passed through two gripping annulus 8, then opposite to squeeze two gripping annulus 8, and then by two gripping annulus 8
It moves two slide bars 9 to move towards, two limited blocks 14 squeeze sponge column 15 in moving process, because of the table of sponge column 15
Face undulate, so compressed sponge column 15 is substantially cylindrical as shown in Figure 5, at the same time two springs 11 divide
It is not stretched by two slide bars 9.Later, compressed sponge column 15 is immersed in the mixed liquor of detergent and water, waits for sponge
Column 15 pulls it after moistening.Then, thumb and index finger loosen, and under the reset response of two springs 11, two slide bars 9 are multiple
Position, and sponge column 15 is reverted into original state, because sponge column 15 has sucked air volume increases in reduction process
The amount for the detergent mixed liquor for adding, but wherein absorbing is not synchronous to be increased, so detergent is mixed in the sponge column 15 after reduction
Although it is still to be evenly distributed, but volume accounting declines, therefore will not drip downwards to close liquid.Then sponge column 15 is bonded
It on the upper surface of white key 1 and white key front bulkhead 3, and reciprocatingly slides, until detergent mixed liquor is uniformly attached to white key 1
On upper surface and on white key front bulkhead 3, because the detergent mixed liquor in sponge column 15 will not drip downwards, can also it avoid
Detergent mixed liquor is dropped onto and is damaged to piano inside piano.So far the leaching of the upper surface to white key 1 and white key front bulkhead 3
Profit processing terminates.
Second step is implemented to infiltrate using infiltration mechanism to the engaging portion of white key side wall 4 and convex edge 2 and white key front bulkhead 3
Processing.First, polished rod 20 and adjusting screw rod 17 is driven to rotate by turning knob 19, the spiral shell on adjusting screw rod 17 and support plate 16
Under the interaction in hole, adjusting screw rod 17 moves down, and polished rod 20, knob 19 and sliding seat 18 is driven to move down, into
And drive connecting rod 21 to move down by sliding seat 18, until the top edge of sponge plate 24 is less than the bottom of sponge column 15.Later
Connecting rod 21 is held, sponge plate 24 and sponge hook 25 are immersed in detergent mixed liquor, because of sponge plate 24 and sponge hook 25
Small volume drawn after sponge plate 24 and sponge hook 25 moisten so the detergent mixed liquor that can be absorbed is also less
Go out and gently dries.Later, sponge hook 25 is fitted to the lower surface of convex edge 2, sponge hook 25 can also be against white key at this time
On front bulkhead 3, moves back and forth sponge hook 25 and infiltrated until by the junction of convex edge 2 and white key front bulkhead 3.Then, by sponge plate
24 are inserted into the first gap 5, move back and forth sponge plate 24, the white key side wall 4 of two neighboring white key 1 is infiltrated.
Third walks, the dirt of the softening generated after being infiltrated on the upper surface of white key 1 and white key front bulkhead 3 using cleaning machine
Dirt is disposed.First, grasping plate 28 is grasped, finger can be passed through from through-hole 29.Then, scraper surface 31 is against white key
It on 1 upper surface, and is moved along the upper surface of white key 1, in moving process, the upper table of dirt and white key 1 is made by taper shovel 32
Emaciated face, which is left, to be come, and two side block blocks 33 can prevent dirt from being fallen to inside piano from the first gap 5.Later in the same way
Dirt removal on white key front bulkhead 3 is fallen.
The dirt removal of 4th step, the softening generated after being infiltrated on white key side wall 4 using cleaning machine is fallen.Equally
Grasping plate 28 is grasped, gap scraper plate 26 is inserted into the first gap 5 later, using gap scraper plate 26 by white key side wall 4
On dirt strike off.Dirt is fallen in order to prevent, and quick, multiple mode may be used in the process scraped, scrapes every time
It completes all to extract out in time and wipe the dirt of attachment.
Embodiment two cleans black key 7 using this cleaning device.The cleaning process of the upper surface of black key 7 and white key 1
Upper surface cleaning process it is similar, the cleaning process in the second gap 6 is similar to the cleaning process in the first gap 5, therefore no longer
It repeats.
The present invention is easy to use, and comprehensive thorough cleaning can be carried out to piano key, dead angle will not be stayed, to avoid
Residual has an impact the health of people and piano itself to dirt for a long time.And destruction is not will produce to piano key.
