Referring to fig. 1 to 4, the moving device 41 further includes two moving sliding rods 12 fixedly disposed between the two fixing plates 11, and a spring is disposed between the fixing plates 11 and the moving sliding rods 12 and pushes the two fixing plates 11 to abut against the side wall of the piano keyboard.

Referring to fig. 1 to 4, a moving slider 13 is slidably connected to the moving slide bar 12, and the moving slider 13 slides on the moving slide bar 12 through driving of an electric slider.

Referring to the attached drawings 1 to 4, the gap detection mechanism 31 further comprises a gap detection sliding cavity 15 located in the lifting slide block 14 and connected with the gap ash blocking slide rods 16 in a sliding mode, two adjacent gap ash blocking slide rods 16 are connected with gap telescopic rods 17 in a sliding mode, the two gap telescopic rods 17 are telescopic rods with the same elasticity, and one end of the gap detection sliding cavity 15 is connected with one positioning slide block 18 fixedly arranged at one end of each gap ash blocking slide rod 16 in a sliding mode.

Advantageously, the positioning slide block 18 is an electric slide block, the positioning slide block 18 pushes the gap dust blocking slide bars 16 to compress the distance telescopic bars 17, and since the elasticity of the two distance telescopic bars 17 is the same, the distance between two adjacent gap dust blocking slide bars 16 is equal, and the width of piano keys is slightly different, the positioning slide block 18 is used for controlling the gap dust blocking slide bars 16 to be aligned with the gap of the keyboard to be cleaned.

Referring to fig. 1 to 4, the ash removing mechanism 32 includes a cleaning slide cavity 20 located in the lifting slide block 14, a middle black key cleaning block 21 is slidably connected in the cleaning slide cavity 20, the middle black key cleaning block 21 is driven by an electric slide block, white key cleaning blocks 22 are fixedly arranged on two sides of the middle black key cleaning block 21, an end black key cleaning block 23 is fixedly arranged on the side of the white key cleaning block 22 far away from the middle black key cleaning block 21, a cleaning slide block 24 is slidably connected in each of the middle black key cleaning block 21, the white key cleaning block 22 and the end black key cleaning block 23, and a cleaning sponge 25 is fixedly arranged at the bottom of the cleaning slide block 24.

Advantageously, the cleaning slider 24 is driven by an electric slider, which is driven to rise if there are black keys below the cleaning slider 24.

Referring to the attached drawings 1 to 4, be equipped with in the lifting slide 14 and being located the interval detects smooth chamber 15 open-top to chamber 19 is accomodate to the dust of clean smooth chamber 20, chamber 19 is accomodate to the dust is close to clean smooth chamber 20 one end torsional spring is connected with the torsional spring and scrapes hawk 27, chamber 19 is accomodate to the dust is used for accomodating the dust that clean sponge 25 was cleared up, torsional spring scrapes hawk 27 and is used for scraping dust on the clean sponge 25, chamber 19 is accomodate to the dust is accomodate the fixed top that is equipped with in clean sponge 25 one end bottom is scraped hawk 28 for the arc, gap ash blocking slide bar 16 articulates and is connected with middle articulated rod 26, middle articulated rod 26 articulates and is connected with and scrapes grey articulated rod 29, middle articulated rod 26 with scrape grey articulated rod 29 and pass through motor drive, works as when gap ash blocking slide bar 16 withdraws, stretches out on the longer pole gap ash blocking slide bar 16 with motor drive rotation on the articulated shaft between middle articulated rod 26, stretch out on the shorter pole middle articulated rod 26 with scrape the articulated shaft on the articulated shaft motor drive of grey articulated rod 29 and change, make the arc contact with dust scraping.

The working principle is as follows:

by observing the arrangement rule of the black and white keys of the piano, both sides of one white key can only have one black key, both sides can also have one black key, and both sides can also not have the black keys.

Initially, the spring between the fixed plate 11 and the movable slide rod 12 is in a relaxed state, the lifting slide block 14 is located at the highest position, the distance telescopic rod 17 is located at the longest length, the middle black key cleaning block 21 is located at one end far away from the gap dust blocking slide rod 16, the gap dust blocking slide rod 16 is located in the lifting slide block 14, and the cleaning slide block 24 is located at the lowest position.

Before cleaning, the fixed plate 11 is clamped between two side plates of a piano, a spring between the fixed plate 11 and the movable slide rod 12 is in a compressed state, the lifting slide block 14 descends, the positioning slide block 18 pushes the gap ash blocking slide rod 16 to move, the gap ash blocking slide rod 16 is just positioned at a key gap position, the gap ash blocking slide rod 16 extends, if a black key is arranged at the gap position, the gap ash blocking slide rod only extends by a half, and if no black key extends completely.

The cleaning slide block 24 corresponding to the half-extended gap dust blocking slide rod 16 moves upwards, the middle black key cleaning block 21 slides towards the dust accommodating cavity 19 along the cleaning slide cavity 20 to wipe off dust, the middle black key cleaning block 21 wipes off dust on the cleaning sponge 25 when the middle black key cleaning block 21 is reset, and dust falls into the gap and falls on the gap dust blocking slide rod 16, the middle hinge rod 26 and the dust wiping hinge rod 29.

In the process of retracting the gap ash blocking slide bar 16, the motor on the hinged shaft between the gap ash blocking slide bar 16 extending out of the longer bar and the middle hinged rod 26 is driven to rotate, the motor on the hinged shaft between the middle hinged rod 26 extending out of the shorter bar and the ash blocking hinged rod 29 is driven to rotate, the middle hinged rod 26 and the ash blocking hinged rod 29 scrape dust on the side face of a key, finally the middle hinged rod and the ash blocking hinged rod are contacted with the arc ash scraping plate 28 to remove the dust on the two bars, the gap ash blocking slide bar 16 is reset, the lifting slide block 14 moves upwards, the moving slide block 13 moves for a distance of a white key along the moving slide bar 12, and the process is repeated until all keys are cleaned.

The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications made to some parts by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
