Description

Technical Field

[0001] This utility model relates to the field of piano cleaning technology, specifically to a novel piano keyboard cleaning device. Background Technology

[0002] Dust and impurities accumulate on pianos not only on the surface but also in the gaps between the keys. Therefore, when cleaning the piano keyboard, it is also necessary to clean the gaps. Ordinary dust removal methods are difficult to reach the gaps, so a thin scraper is usually inserted into the gaps to scrape the dust and impurities out or directly adhere to them for cleaning.

[0003] For example, in the public announcement (CN213103345U), a piano keyboard gap cleaning device is described, in which a scraper head is inserted into the gap to clean it. The thickness of the scraper head is a fixed value, but the gap width varies for different types of pianos. If the thickness of the scraper head is greater than the gap, it will be difficult to insert. If the thickness is less than the gap, the cleaning effect will be poor due to insufficient contact force.

[0004] This solution provides a novel piano keyboard cleaning device that, through the use of a thin scraper with a special structure, can adaptively adjust to the width of the gaps. Utility Model Content

[0005] The present invention aims to at least solve the problem in the prior art that the thickness of the scraper cannot adapt to the different gap widths of the piano keyboard.

[0006] This solution provides a novel piano keyboard cleaning device, achieved through the following specific technical means: it includes a handle cylinder, with a scraper fixed to the front end of the handle cylinder. The front and rear sides of the scraper are covered with airbags filled with gas. As the scraper is inserted into the gaps of the piano keyboard, as the scraper is inserted downwards, the excess gas in the lower part of the airbag is squeezed upwards by the gaps in the keyboard and moved to the upper middle part of the airbag, so that the overall thickness of the scraper can be adapted to gaps of different widths.

[0007] Preferred technical solution 1: The scraper is covered with a cleaning cloth or cleaning paper towel.

[0008] Preferred technical solution 2: A protective cover is fixed on the handle cylinder, a rotating shaft is rotated in the protective cover, the cleaning cloth or cleaning paper towel is wrapped around the rotating shaft, and the end of the cleaning cloth or cleaning paper towel is pulled out from the protective cover and wrapped around the scraper.

[0009] Preferred technical solution 3: A protective frame is fixed to the bottom side of the handle cylinder. The protective frame surrounds the middle of the scraper. At the same time, guide rollers rotate on both the front and rear sides of the protective frame. The guide rollers are close to the scraper. After the cleaning cloth or cleaning paper towel is pulled out from the protective cover, it passes around the guide rollers so that the cleaning paper towel is close to the airbag on the scraper.

[0010] Preferred technical solution four: A soft brush is installed at the top of the handle cylinder.

[0011] Preferred technical solution five: An adjusting component slides in the handle cylinder, the top end of the scraper extends into the adjusting component through a window opened in the bottom wall of the handle cylinder, and the lateral end of the adjusting component extends out from a vertical hole opened in the handle cylinder wall.

[0012] The above structure gives this solution the following advantages:

[0013] 1. By setting airbags on both sides of the scraper, the scraper can be adaptively adjusted to fit the width of the gap when it is inserted into the gap of the piano keyboard, so as to achieve the technical effect of scraping and cleaning by the scraper adhering to the gap wall on both sides.

[0014] 2. The scraper, together with the covering cleaning cloth or paper towel, can clean the gaps. The cleaning cloth or paper towel can be replaced when it gets dirty.

[0015] 3. Attach a soft brush to the top of the handle to increase cleaning options. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 A novel piano keyboard cleaning device includes a handle cylinder 1, with a scraper 2 fixed to the front end of the handle cylinder 1. The thickness of the scraper 2 is less than the width of the keyboard gaps. Airbags 21 filled with gas are laid on both the front and back sides of the scraper 2. As the scraper 2 is inserted into the piano keyboard gaps, the excess gas in the lower part of the airbag 21 is squeezed upward by the keyboard gaps and moved to the upper part of the airbag 21, causing the upper part to expand. This achieves the technical effect that the overall thickness of the scraper 2 can adapt to gaps of different widths.

[0025] Please see Figures 1-3 A novel piano keyboard cleaning device is described, in which a cleaning cloth or paper towel is wrapped around a scraper 2. The scraper 2 is used to insert the cloth or paper towel into the gaps of the piano keyboard to wipe away dust and debris. A protective cover 3 is fixed on the handle cylinder 1, and a rotating shaft is located in the protective cover 3. The cleaning cloth or paper towel is wrapped around the rotating shaft, and the end of the cleaning cloth or paper towel is pulled out from the protective cover 3 and wrapped around the scraper 2. When the extended cleaning cloth or paper towel becomes dirty, this section can be removed and replaced. The protective cover 3 and the handle cylinder 1 are detachable for easy replacement of the cleaning cloth or paper towel. The cleaning paper towel is a paper towel with a certain degree of toughness, and the cleaning cloth is preferably made of non-woven fabric.

[0026] Please see Figures 1-4 A novel piano keyboard cleaning device has a protective frame 4 fixed to the bottom side of the handle cylinder 1. The protective frame 4 surrounds the middle of the scraper 2. At the same time, guide rollers 5 rotate on both the front and rear sides of the protective frame 4. The guide rollers 5 are close to the scraper 2. After the cleaning cloth or cleaning paper towel is pulled out from the protective cover 3, it passes around the guide rollers 5 so that the cleaning paper towel is close to the airbag 21 on the scraper 2. Elastic pressure rollers 6 are rotatably installed on both the front and rear sides of the bottom of the handle cylinder 1. The elastic pressure rollers 6 are pressure rollers with an elastic layer on the surface. After the cleaning cloth or cleaning paper towel is pulled out from the protective cover 3, it passes through the gap between the elastic pressure roller 6 and the wall of the handle cylinder 1 and is pressed onto the handle cylinder 1 by the elastic pressure roller 6 to prevent the cleaning cloth or cleaning paper towel from slipping off the scraper 2.

[0027] Please see Figures 1-3 A new type of piano keyboard cleaning device has a soft brush body 7 installed at the top of the handle cylinder 1, and the handle of the soft brush body 7 is inserted into the top opening of the handle cylinder 1.

[0028] Please see Figures 1-5A novel piano keyboard cleaning device has an adjusting element 8 sliding in the handle cylinder 1. The top of the scraper 2 extends into the adjusting element 8 through a window 12 on the bottom wall of the handle cylinder 1. The extension and retraction of the scraper 2 are controlled by the adjusting element 8. When not in use, the scraper 2 is retracted into the handle cylinder 1 for protection to avoid collision and deformation. At the same time, the cleaning cloth or cleaning paper towel that is pulled out can be located between the protective frame 4 and the handle cylinder 1. The horizontal end of the adjusting element 8 extends out from the vertical hole 11 on the wall of the handle cylinder 1 and slides along the vertical hole 11 with damping, so that the extension and retraction of the scraper 2 can be controlled by pushing the horizontal end.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
