[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction port having a rotating brush for a vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, this kind of suction port shown in FIGS. 4 and 5 is known. In the drawing, reference numeral 1 denotes a housing of a suction port body, in which a rotary brush chamber 2 for accommodating a rotary brush described later is integrally formed, and a suction port 3 is opened in the rotary brush chamber 2; The suction part 4 is connected. Reference numeral 5 denotes the above-mentioned rotary brush, in which a pulley 6 is formed integrally, and supporting shafts 7, 7 are fixed to both ends. Reference numerals 8 and 9 denote ribs formed integrally with the housing 1 and form a part of the rotary brush chamber 2. These ribs 8 and 9 have through holes 1
0 and 11 are provided, and the vicinity of the end of the rotating brush 5 is loosely fitted.

[0003] Reference numeral 12 denotes a belt chamber integrally formed with the housing 1, which is separated from the rotary brush chamber 2 by the rib 8. A bearing 13 for supporting one of the support shafts 7 is fixed to the belt chamber 12, and a motor 14 is also housed therein. Reference numeral 15 denotes a belt for transmitting the rotation of the motor 14 to the pulley 6, whereby the rotating brush 5
At high speed in the direction of the solid arrow. A bearing chamber 16 is formed integrally with the housing 1 and is separated from the rotary brush chamber 2 by the rib 9. This bearing chamber 16
A bearing 17 that supports the other of the support shaft 7 is fixed to the support shaft 7. 18 is the motor 14 on which the belt 15 is
Pulley.

[0004] In the suction port body configured as described above, dust, cotton dust, and the like on a carpet or the like are scraped up by the rotating brush 5, and are sucked from the suction port 3 into the suction section 4. Further, a part of dust, cotton dust, and the like to be sucked by the suction unit 4 passes through a gap between the rotary brush 5 and the rib 8 loosely fitted in the through hole 10 and adheres to the belt 15. If the suction port is used for a long period of time with dust or the like adhered thereto as described above, the surface friction coefficient of the belt 15 is significantly reduced, and rotation slip, heat generation, smoke generation, noise, and the like are generated.

By the way, the rib 8 in the through hole 10
The gap between the rotating brush 5 and the rotating brush 5 is necessary to absorb variations in parts and variations in assembly, and is also necessary in consideration of fluctuations in rotating load. Heretofore, in order to prevent dust and the like from passing through the above-mentioned gap, there has been known an apparatus in which a filling such as foam sponge or felt is attached to the gap.

[0006]

When the padding is attached to the gap, dust and the like can be prevented from passing therethrough, but the padding is pressed against the outer peripheral surface of the rotating brush in a compressed state. Therefore, this pressure contact force is large, and heat is generated due to friction. This heat is greater when the center of the rotary brush and the through hole of the rib are shifted. This invention solves the problem of the above-described conventional suction port body, and even if dust or the like that has passed through the gap adheres to the belt, a vacuum cleaner that can remove the dust and the like can be used. It is an object to provide a suction port body.

[0007]

SUMMARY OF THE INVENTION A suction port of a vacuum cleaner according to the present invention is a suction port of a vacuum cleaner having a rotary brush to which rotation is transmitted from a power source such as a motor via a belt. A dust remover provided with a flexible cleaning member, wherein the tip of the cleaning member of the dust remover contacts the transmission surface of the belt.

[0008]

In the suction opening of the vacuum cleaner constructed as described above, dust or the like that has passed through the gap and adhered to the transmission surface of the belt is dropped by the dust remover and cannot reach the pulley of the motor or the like. Absent.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a main part of a suction port body of a vacuum cleaner relating to the present invention, and the same parts as those in FIGS. 4 and 5 used for describing a conventional example are denoted by the same reference numerals. Therefore, the detailed description is omitted. 20 is a trash remover,
As shown in (a) or (b) of FIG. 2, a base 21 made of plastic or the like and a cleaning member 22 having a base end fixed to the base are formed. This cleaning member 22
Consists of flexible nylon thread or animal hair. 23 is a screw for fixing the base 21 to the housing of the suction port body. The dust remover 20 is installed between the rotary brush pulley 6 and the motor pulley 18 (fixed to the housing).
The end of the cleaning member 22 is in contact with the transmission surface of the belt 15.

[0010] In the suction port of the vacuum cleaner having the above configuration, dust and the like floating in the belt chamber are denoted by reference numeral 2.
Even if it adheres to the transmission surface (inner peripheral surface) of the belt 15 as shown by 4, it is dropped by the dust remover 20 and the pulley 1
No eight.

FIG. 3 shows another embodiment of the dust remover 20. This dust remover 20 is made of a non-woven fabric or the like,
It is cheaper than that of FIG. In this trash removal tool 20,
An adhesive 25 is applied to the base, and a cleaning member 22 is provided.
Are provided with a plurality of slits 26 for improving flexibility. The adhesive 25 is used to fix the dust remover 20 to the housing of the suction opening.

In the above embodiment, the dust remover 20 is installed in front of the pulley 18 of the motor.
May be installed before the pulley 6 of the rotating brush. In the above embodiment, a belt using a flat belt as the belt 15 has been described. However, the present invention can be applied to a belt using a toothed (timing) belt and a pulley using a toothed pulley. In the above-described embodiment, the example of the thread, the hair, the nonwoven fabric, or the like has been described as the cleaning member 22, but any other member may be used as long as it has a restoring property. In the above embodiment, the rotating brush 5 is
Although the description has been given of the one rotated by the aerodynamic (turbine) fan, the one rotated by the aerodynamic (turbine) fan via the belt can also be implemented.

[0013]

As described above, according to the present invention, the transmission surface of the belt is always maintained during the rotation of the rotating brush, regardless of the gap between the rotating brush and the ribs, and regardless of the mounting position of the rotating brush. Is cleaned, it is possible to prevent harmful slip, heat, smoke, and noise of the belt caused by the attachment of dust, cotton dust, etc. to the transmission surface of the belt, and to maintain quality and durability. The expected effect is great.
