Description

[Detailed Description of the Invention] The present invention relates to a blackboard wiping cleaner and is intended to improve usability.

In general, blackboard wiping cleaners are designed to clean by pressing a blackboard wiping tool against the blackboard wiping sliding surface and sliding it back and forth. The drawback was that the ingredients were attracted to it and the slide became heavy, making it difficult to use.

For this reason, there are some cases in which protrusions are provided on both sides of the suction port, and these protrusions create a small gap between the suction port and the part of the blackboard wiping tool that faces it, thereby preventing the suction from sticking. However, because the width of this protrusion is narrow, there is a risk that it will be buried in the blackboard wiping tool, making it ineffective, and also due to the presence of frictional resistance between the blackboard wiping tool and the sliding surface of the blackboard wiping tool. As before, the slide was heavy and difficult to use.

The present invention has solved such conventional drawbacks, and one embodiment of the invention will be described below with reference to the drawings. 1 is a vacuum cleaner main body, which has an electric blower (not shown) built in, and a is formed by the dust collection chamber 2.

This dust collection chamber 2 has a built-in dust collection bag/filter 3, and the dust collection bag/filter 3 is held via a rubber cap 3a.

Reference numeral 5 denotes a main body lid placed over the vacuum cleaner main body 1, which can be opened and closed with a hinge so that the dust collection bag 3 can be attached to and removed from the dust collection chamber 2.

Reference numeral 6 denotes a slit-shaped suction port provided on the blackboard wiping sliding surface 5a of the main body lid 5, which communicates with the dust collection chamber 2, and by sliding the blackboard wiping tool on the suction port 6, the blackboard wiping tool is removed. Vacuums up adhering chalk powder.

Reference numerals 7 and 7 denote rotating belts disposed on both sides along the long side of the suction port 6, and a pair of rotating shafts 8a pivotally supported on the main body lid 5.
, sb, facing the blackboard wiping sliding surface 5a, and is rotated by the slide of the blackboard wiping tool.

In the above configuration, when a blackboard wiping tool is placed on the blackboard wiping sliding surface 5a, this blackboard wiping tool is moved by the rotating belt I.

Supported by I, a slight gap is formed between the suction port 6 and the suction port 6.

In other words, the rotating belts 1 and 7 are designed to be sufficiently wide so as not to be buried directly in front of the blackboard wiping, and there is a slight gap between the suction port 6 and the other blackboard wiping sliding surface 5a. It comes to be located after.

And when you slide this 11 blackboard cleaning tool back and forth,
The rotating bell) 7.7 is rotated by the frictional force with the blackboard wiping tool, and the blackboard wiping tool slides lightly with no frictional resistance between it and the blackboard wiping sliding surface 5a.

Incidentally, in this embodiment, the uneven strips 9 are provided on the surface of the rotating belt 7.7, so that the blackboard wiping tool is the rotating belt I.

7 to prevent it from slipping, and to prevent the sliding resistance of the blackboard cleaning tool from increasing due to the sliding resistance generated between the two, which allows the blackboard cleaning tool to slide more easily and improve chalk powder separation. There are advantages to doing so.

As described above, according to the present invention, the blackboard wiping tool can be easily slid and the usability is significantly improved, and its practical value is considerable.
