Description

[Detailed description of the invention] A. Field of industrial application The present invention relates to a vacuum cleaner suction tool used in a portable vacuum cleaner.

B. Prior Art Conventionally, there is a floor suction tool in which a turbo fan provided at a suction port is rotated using the suction force of a vacuum cleaner, and a rotating brush provided at the suction port is driven by the turbo fan. However, this suction tool needs to have a strong suction force, and there is a problem in that it cannot be used in the suction port of a rechargeable portable vacuum cleaner, which has a small suction force.

C. Purpose of the invention The purpose of the invention is to enable easy cleaning by rotating a brush body provided at the suction port as the vacuum cleaner moves to scrape out dirt hidden inside the carpet.

D. Structure of the invention The suction tool for a vacuum cleaner of the invention consists of a suction port body having a brush storage chamber that is removably fitted into the suction port of the vacuum cleaner body, and a rotating drive wheel attached to both sides of a spiral brush. The brush body has a shaft formed on the side surface of the drive wheel and is rotatably engaged with a mounting hole provided on both sides of the brush storage chamber.

E. Embodiments Hereinafter, embodiments of the present invention shown in the drawings will be described.

Reference numeral 1 denotes a main body of a portable vacuum cleaner, which has a built-in rechargeable battery and an electric blower (both not shown) driven by the battery, and a main body case having a handle 2 and a switch button 3 on the top. 4 and a dust case 7 which houses a dust collection filter (not shown) and has a horizontally elongated suction port 6 which is detachably connected to the front surface of the main case 4 by means of a clamp button 5.

Reference numeral 8 denotes a suction tool which is removably fitted into the suction port 6 of the vacuum cleaner main body 1.

The suction tool 8 comprises a suction mouth body 9 and a rotating brush body 10.
The suction port body 9 is integrally formed of a synthetic resin material with a connecting portion 11 having a generally inverted U-shape in cross section that fits into the suction port 6, a groove portion 12 of the connecting portion and a brush storage chamber 14 with a bottom opening that communicates with a rear opening 13, and the inner surface of the brush storage chamber 14 is provided with a number of ribs 15, 15... that come into contact with the rotating brush body 10. The rotating brush body 10 is formed by fixing a spiral brush 18 made of two twisted wires 16 with a synthetic resin brush 17 sandwiched between them, and fixing synthetic resin drive wheels 19, 19 on both sides of the brush, and axles 20, 20 formed to protrude from the outer surfaces of the drive wheels 19, 19 are connected to bearing portions 21, 21 formed on both sides of the brush storage chamber 14 and mounting holes 22, 22.
The shafts 20, 20 of the drive wheels 19, 19 are inserted into the mounting holes 22, 22 by pushing them in using the elasticity of the synthetic resin material of the brush storage chamber 14. The diameter of the spiral brush 18 is made larger than that of the drive wheel 19 to improve the effect of sweeping out dirt from inside the carpet.

In the above configuration, when dust on the table or floor is sucked in, the suction tool 8 is not used, and the dust is directly sucked in through the suction port 6 of the cleaner body 1.

On the other hand, when partially cleaning a carpet, the suction tool 8 is fitted into the suction port 6 of the vacuum cleaner main body 1, the rotating brush body 10 is brought into contact with the carpet, and the vacuum cleaner main body 1 is moved back and forth. wheel 1
9 and 19 rotate, and along with this, the spiral brush 1
8 also rotates to scrape out dirt hidden deep in the carpet and suck it into the vacuum cleaner body 1.

F. Effects of the invention Since the vacuum cleaner suction tool according to the invention is constructed as described above, by connecting it to the suction port of a portable vacuum cleaner with weak suction power, it can remove dirt that has fallen on the carpet or hidden inside the suction tool. You can easily scrape out the dirt that is present, and you can easily clean the carpet.
