Abstract

PURPOSE:To obtain this nozzle excellent in usability and durability by constituting an agitator rotated by a driving source and provided in a floor nozzle main body, of a roughly columnar rotor, and plural pieces of brush bodies formed in the outermost peripheral part of a stirring body. CONSTITUTION:A main agitator 22 is held so as to be freely rotatable by a bearing A23 and same B24 provided on both side chamber walls of a suction chamber 16. When a motor 19 is operated, a belt 31 transfers this rotation and the agitator 22 executes a rotation in the upper forward lower backward upper directions, and by the repelling action of a stirring body 33 and the suction force of a vacuum cleaner, dust is isolated, and sucked and collected from the non-cleaning surface of a carpet, etc., and also, a brush body 36 is intruded into the inside of the carpet, by which the dust of the inside of the carpet is scraped out. In this case, waste thread 39, etc., is wound to brush body 36, but since the dimension T of the brush body 36 is short, depth of penetration to the brush body of the waste thread 39 is small, and also, it is not wound directly to the rotor and it can easily be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor nozzle for a vacuum cleaner with an agitator.

Conventional technology Conventionally, this type of floor nozzle agitator was developed in Japanese Patent Application Laid-Open No. 1986-
The configuration disclosed in Japanese Patent No. 161334 was adopted. Specifically, as shown in FIG. 5, an agitator 2 and its driving source are installed inside the floor nozzle body 1, and the agitator 2 is made of a flexible material on the circumferential surface of a rotor 3. It was constructed by providing a protruding strip 4, and a large number of protrusions 5 were formed on at least one surface of the protruding strip 4. As the agitator 2 rotates, the protrusions 5 of the protruding strip 4 stir up dust in the room, and the dust is sucked into the vacuum cleaner body, thereby collecting dust in the room.

Problem to be Solved by the Invention However, the protrusions 5 cannot be constructed for a long time due to wear resistance and strength, and as a result, although the performance of collecting dust on the carpet is excellent, it is insufficient in removing dust etc. from inside the carpet. It wasn't performing well.

Also, what has excellent blowing performance is the configuration in which brush bristles 8 are implanted on the circumferential surface of the rotor 7 of the conventional agitator 6 as shown in Fig. 6, but with this configuration, lint, hair etc. The bristles 8 become entangled with the roots of the brush bristles 8, and eventually wrap around the entire agitator 6, requiring a great deal of effort to remove them.

An object of the present invention is to solve this problem and provide an agitator with excellent usability and durability.

Means for Solving the Problems In order to solve these conventional problems, the means of the present invention are as follows:
The agitator, which is rotated by a drive source and installed inside the floor nozzle body, is composed of a substantially cylindrical rotor, a stirring body made of a flexible material attached continuously in the longitudinal spiral direction of the outer circumferential surface of the rotor, and this stirring body. A plurality of brush bodies are formed on the outermost periphery of the body, and the brush bodies are made of a plurality of fibrous wear-resistant materials.

Function: In the above means of the present invention, by providing a plurality of brush bodies on the outermost periphery of the agitation resistor, the brush bodies can penetrate not only onto the carpet but also inside the carpet to scrape out dirt, etc. inside the carpet. Since there is an agitator between the base of the body and the rotor, lint, hair, etc. can be easily removed without being directly wrapped around the rotor.

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

1 to 4, the floor nozzle body 11 is obtained by connecting upper and lower body members 13 and 14 through a bumper 12, and a lower opening is provided in the front interior of the nozzle body 11.
A suction chamber 16 is formed.

The center of this suction chamber 16 communicates with a communication pipe 17 that is held between the upper and lower body members 13 and 14 so as to be able to move up and down at the rear of the floor nozzle main body 11, and a connection pipe 18 that is rotatably connected to the communication pipe 17. Moreover, an extension tube connected to the suction side of the vacuum cleaner via a hose is detachably connected to this connecting tube 18.

A motor 1 for driving an agitator is installed on the left and right sides of the connecting pipe 18.
9 and a control section 20 for controlling the same are installed inside, and are supplied with power through a power cord 21.

22 is a main agitator provided in the suction chamber 16 in parallel thereto, and bearings A23.22 are provided on both side walls of the suction chamber 16. It is rotatably held by the same B24.

The shaft 25 of the agitator 22 has bearings A23 and B2.
The sub-agitator 26 protrudes further to the side than 4.
is attached. This sub-agitator 26 has an opening A27 formed in the side wall of the floor nozzle body 11. It is as if we are facing the same B28.

Further, a belt 31 is pulled between a pulley 29 provided on one side of the agitator 22 and a pulley 30 provided on the rotating shaft of the motor 19, and the agitator 22 and the sub-agitator 26 are forcibly driven.

The agitator 22 is composed of a substantially cylindrical rotor 32 and an agitator 33 made of a flexible material that is continuously attached to the outer peripheral surface of the rotor 32 in a longitudinal spiral direction.

On the other hand, the auxiliary agitator 26 includes a cap-shaped rotor 34 wrapped around its outer periphery, and three stirring blades 35 protruding from the outer periphery of the rotor 34. This stirring blade 35
is formed integrally with the rotor 34 from a flexible material such as rubber.

Reference numeral 36 designates a plurality of brush bodies formed on the stirring body 33 by flocking or the like. The plunger body 36 is dimensioned to be able to enter into the interior of the carpet. The stirring body 33 is the engaging part 3
7 and is engaged with a groove 38 provided in the rotor 32, so that a part thereof can come into contact with the carpet during carpet cleaning work.

Next, the first operation in the above configuration will be explained.

When the motor 19 is operated, the belt 31 transmits this rotation, and the agitator 22 rotates in an upward direction, forward direction, downward direction, backward direction, and upward direction, and the repelling action of the agitator 33 and the suction force of the vacuum cleaner clean the carpet. Dust is released and sucked from non-cleaned surfaces such as the like, and the dust inside the carpet is scraped out by entering the brush body 36 into the inside of the carpet.

At this time, lint 39 and the like get wrapped around the brush bristles 36, but
Since the dimension T of the brush body 36 is short, the amount of biting of the lint 36 into the brush body is small and can be easily removed.

Further, in this embodiment, the brush body is described as a flocked brush body, but the same effect can be obtained even if the brush body 40 is formed into an agitator body 41 as shown in FIG.

Effects of the Invention As described above, the present invention provides, in the means of the present invention, a plurality of brush bodies formed on the outermost part of the stirring body, so that the brush bodies can enter not only the top of the carpet but also the interior of the carpet. It is possible to scrape out dirt and the like, and since there is an agitator between the root of the brush body and the rotor, lint, hair, etc. can be easily removed without being directly wrapped around the rotor.
