Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a suction tool for use in gaps, etc., which is used as an accessory for vacuum cleaners.

BACKGROUND ART Conventionally, this type of suction tool has a structure as shown in FIGS. 5 and 6.

That is, 21 has a suction port 2 with a substantially rectangular cross section at the tip.
2. The main body of the suction tool has a connecting part 23 connected to a hose at the rear end, and 24 is a brush detachably attached to the suction port 22. The brush 24 has two wires 25
are twisted together and the brush bristles 26 are held between them.
A wire 2 is attached to the locking portion 27 of the opposite short piece of the suction port 22.
Both end bent portions 28 of 5 are removably locked.

Problems to be solved by the invention When using such a conventional suction tool, when cleaning gaps between furniture, etc., the brush 24 is removed,
A brush 24 is also attached when cleaning grooves and the like. As described above, in the past, it was necessary to attach and detach the brush 24 depending on the conditions of the area to be cleaned, which was not easy to use, and moreover, the removed brush 24 could be lost. Furthermore, the brush 24 substantially reduces the suction area of the suction port 22, causing the problem that dust such as cotton dust blocks the suction port 22.

The present invention solves these problems and provides a suction tool that is easy to use.

Means for Solving the Problems In order to solve the above conventional problems, the present invention
A suction tool body made of synthetic resin, which has a connection part to the vacuum cleaner side on the base side, is substantially flattened from the middle in the longitudinal direction toward the front end, and has a suction port formed at the tip;
The suction device has a brush body that is pivotally supported on the front outer surface of the suction device body and is covered with the front end of the suction device body so as to be rotatable back and forth. The brush frame includes a brush frame having an opening, and a brush installed in the rear opening of the brush frame, and a bar-shaped stopper piece is formed between the front opening and the upper opening of the brush frame, A locking recess for the stopper piece is provided on the upper edge of the suction mouth of the suction tool body, and the inner bottom surface of the brush frame has a circular shape that passes through the upper and lower mouth edges of the suction mouth and is centered around the rotational fulcrum of the brush body. It is set in an arc shape that matches the trajectory.

Effect According to the present invention, by rotating the brush body, the suction port can be opened substantially directly or opened via the brush, and the suction port can be opened according to the situation and form of the part to be cleaned. You can do a lot of cleaning. In addition, it is very easy to use as all you have to do is rotate it, and there is no need to lose the brush body. Further, as the brush body rotates, the arc-shaped inner bottom surface of the brush frame slides into contact with the upper and lower mouth edges of the suction port, and a so-called wiping action is exerted between the two, thereby scraping off the adhered dust.

Example Examples thereof will be described below with reference to the accompanying drawings.

In FIGS. 1 to 4, a suction device main body 2 having a connecting portion 1 to the vacuum cleaner side on the base side is formed into a substantially flat shape from the middle toward the front, and has a suction port 3 at the tip. The opposing long edge of the mouthpiece 3 is formed into a curved shape that projects outward. 4 is a locking recess provided at the top end of the suction device main body 2; 5 is a guide portion formed by protruding the lower mouth edge of the suction port 3 forward; and 6 is a hole bored at the top of both sides of the substantially flat part of the suction device main body 2. This is the shaft support hole provided. Reference numeral 7 denotes a brush body which is rotatably attached to the front part of the suction device main body 2, and includes a brush frame 11 having openings 8, 9 and 10 at the front, upper and rear sides, respectively, except for the bottom part, and a brush body 7 at the rear. It consists of a brush 12 installed in the longitudinal direction from the tip edge of the opening 10. The brush body 7 is rotatably attached to the suction tool main body 2 by fitting a shaft 13 protruding inwardly from both side walls of the brush frame 11 into the shaft support hole 6. . The opposing mouth edge on the long side of the front opening 8 is curved like the mouthpiece 3, and a bar-shaped stopper piece 14 is formed between the front and upper openings 8 and 9. be. Further, the inner bottom surface 15 of the brush frame 11 passes through the upper mouth edge end of the suction port 3 and the tip of the lower guide portion 5, and the shaft 1
It is set in an arc shape that coincides with a circular locus centered at 3.

In the above configuration, FIGS. 3 and 4 show the brush 12 when not in use, and at this time, the brush body 7 is in a position where the front opening 8 of the brush frame 11 matches the suction port 3, and the stopper The piece 14 engages with the locking recess 4 of the suction device main body and acts to maintain that position.

In this state, narrow gaps, grooves, etc. can be cleaned through the suction port 3.

Next, when a constant clockwise rotational force is applied to the brush body 7, the stopper piece 14 climbs over the locking recess 4, and the brush body 7 slides over the guide portion 5 and the upper edge of the suction port 3. Moving arc-shaped inner bottom surface 1
5 as a guide, the brush 12 moves forward and diagonally downward, and the stopper piece 14 moves toward the suction tool main body 2.
It is fixed when it hits the top surface of. Figure 1 shows the state at that time.
can be reliably suctioned through the As the brush body 7 rotates, the arc-shaped inner bottom surface 15 of the brush frame 11 slides in contact with the upper and lower edges of the suction port 3, so that a wiping action is exerted between them to remove the deposits. Dust is scraped away. Therefore, the rotation of the brush body 7 will not become uncertain or the effective opening area of the suction port 3 will not become small due to dust adhesion.

Effects of the invention As described above, according to the invention, the suction port can be set according to the shape of the part to be cleaned simply by rotating the brush body, thus improving usability and ensuring reliable dust suction. Moreover, it is possible to prevent loss of the brush body. Moreover, the rotary operability of the brush body is maintained well at all times, and the opening of the mouthpiece is maintained precisely, resulting in excellent effects.
