  However, with the above cleaning tool, it takes a long time to wipe off the dirt on a single screen door with a wiping cloth, and the dirt on the wiping cloth adheres to the wiping cloth with use, so the dirt can be removed with water or a cleaning solution. It is necessary to clean and wash frequently. Furthermore, there is a problem that contaminants that are wiped off with a wiping cloth at the time of cleaning are scattered in the sash groove or veranda where the screen door is fitted, and the dust that falls in the sash groove must be removed with another cleaning brush. Have.

  An object of the present invention is to solve such a problem, and it is possible to remove not only dirt of a screen door but also dirt such as a sash groove and a veranda around the screen door. An object of the present invention is to provide a cleaning tool capable of shortening the cleaning time, reducing the number of times of cleaning the cleaning brush, and cleaning the contaminants to be removed without being scattered or dropped.

  The cleaning tool of the present invention comprises a connection pipe part that is detachably connected to the tip side of the suction hose of the vacuum cleaner, and a suction port connected to the tip part of the connection pipe part, The suction port body is formed in a rectangular shape whose plane is long in the lateral width direction and short in the front-rear direction, and its internal space is partitioned into an upper passage and a lower passage communicating with the internal passage of the connection pipe portion. The suction port body is provided at the front side portion thereof so as to communicate the front suction port with the upper side passage, and at the bottom side portion thereof, the bottom side suction port is provided so as to communicate with the lower side passage. Is attached with a surface brush plate with a surface brush made of synthetic fibers or cloth made of countless short naps lying down and dense, and a relatively hard and long brush is planted at the bottom suction port. The installed brush stand is attached and the front The front end portion of the connection pipe portion is connected to the rear end portion of the suction port body so as to be rotatable relative to each other, and the inner passage of the connection pipe portion is provided with a closing plate for closing a half of the cross section of the inner passage. By rotating the connection pipe part 180 degrees with respect to the suction port body, the internal passage of the connection pipe part communicates with the upper passage, and the internal passage of the connection pipe part communicates with the lower passage. It is characterized in that it can be switched to a state to be performed.
