2. Description of the Related Art Recent advances in appliances such as telephones, word processors, personal computers, etc. and life-related equipment have been remarkable, and as a result, their operability, decorativeness,
The shape and the like are not limited to simple combinations of planes and curved surfaces, but have fine irregularities, minute spaces, minute gaps, and the like, and dust prevention and dust removal measures tend to be delayed.

[0003] In a conventional vacuum cleaner, most of the methods for removing dust on gaps and uneven surfaces are vacuum suction methods, which have a structure having a brush or the like fixedly embedded in a dust suction portion of a suction body. Because of this, the suction port is a fixed linear structure, and the dust removal surface is the tip of the brush, whereas the actual dust suction port is located away from the dust removal surface. In the case of objects, equipment having a curved surface, a fine gap, or the like, the dust removing effect tends to be significantly impaired.

[0004]

Generally, fine dust and dirt have a property that they easily accumulate in a concave portion of an uneven surface or a corner portion that becomes a corner, and easily stay in a curved surface or a minute space. The biggest drawback of the conventional vacuum dust cleaner is that the structure of the dust suction unit is poorly adaptable to the irregularities and minute gaps on the dust removal surface, and the more it becomes a curved surface or minute space, the more the air resistance increases. Etc. significantly reduced,
As a result, the dust removing effect was deteriorated. An object of the present invention is to provide a mouthpiece having a simple structure that solves these problems.

[0005]

According to the present invention, in order to solve the above-mentioned problems, the convex or concave portion is formed by covering the flat or curved surface having irregularities with a flat plate made of a semi-flexible material. A plane or a curved surface connecting the vertices of the corners, enclosing the space of the concave portion, the minute space, etc., and separating from the general open space, the concave space, the minute gap, or the corner space of the corner surrounded by the flat plate. The vacuum suction force is concentrated and generated only in the space, and the air volume and the wind speed in the various spaces are increased, so that not only the dust suction force is not weakened but also the suction body which is rather strengthened is provided at a low cost. It was done.
