DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cleaning device, and particularly to a ceiling cleaning device that can simply and easily clean indoor ceilings.

(Prior art and its problems) When cleaning apartments, buildings, and even households, floors, walls, etc. are generally cleaned using a vacuum cleaner, an electric mop, a rag, etc.

By the way, various types of equipment have been developed for washing and cleaning floors and walls, and are used in households and businesses, but when cleaning ceilings, suitable equipment and tools such as these are required. Since it has not been developed yet, workers can either set up a ladder or chair on the floor, etc., and use motsupu or a rag to do it manually, or attach an extension hose to the tip of the vacuum cleaner to increase the suction power of the vacuum cleaner. In addition to the method of sucking in the dust from the ceiling by force, there was no method that could completely clean the ceiling except by scraping the dust off the ceiling with a rotary mop or the like.

In particular, methods such as scrubbing dust off the ceiling surface with a rotary motsup, etc., cause the dust to fly downwards, causing the worker to directly cover his/her head and making the room even more covered in dust. There is also a risk that the dust may induce asthma (or rhinitis, etc.).

In addition, when cleaning interiors using the conventional methods described above, it takes a lot of effort and time compared to cleaning floors and walls, and it also takes a lot of effort and time to clean the interior of the house using the conventional methods mentioned above. In such cases, because the building is designed with a high ceiling, it takes more time than normal work, and in most cases, the work is left unattended.

Therefore, in recent years, it has become possible to work on ceilings as easily as possible in the same way as floors and walls. Currently, there is a strong desire to develop equipment that can complete the process.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and includes a case body that supports a cleaning rotary brush rotated by a drive source so that the cleaning liquid inside the case body is transferred to the lower surface of the cleaning rotary brush.

It is characterized in that it is configured to be rotatably supported in parallel with this.

In addition, the present invention provides a removable lid with an opening in the upper part of the case body that has an opening window in the center for protruding a rotating cleaning brush, and support rollers for maintaining the height of the brush in each corner. It is also characterized in that the rotating cleaning brush disposed at the center of the opening of the case body is a cleaning brush whose surface is treated with Epoclean.

Furthermore, the present invention provides a drive mechanism for the cleaning rotating brush in which a small diameter pulley is fitted to the tip of the drive shaft of the drive motor, a large diameter pulley is fitted to one end of the support shaft of the cleaning rotating brush, and there is a gap between these two pulleys. A drive mechanism consisting of an endless belt, a small-diameter gear fitted to the end of the drive shaft of the drive motor, and a large-diameter gear fitted to the end of the spindle of the cleaning rotating brush. It is also characterized by the use of a drive mechanism constructed by interposing planetary gears.

Furthermore, the ceiling cleaning device of the present invention is characterized in that a bar of a certain length that can support the case body is connected to the lower part of the case body, and a lifting adjustment mechanism is connected to the lower part of the case body. Another major feature is that the case body is configured to be adjustable in height and can be moved up and down.
