Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the suction port of a vacuum cleaner, and in particular improves the bearing part of the rotary brush, and prevents lint etc. This relates to a suction port for vacuum cleaners that prevents dirt from entering.

B. Prior art] □ Various devises and improvements have been made to prevent dirt such as lint from entering the bearing of a rotating rotary brush (Utility Model Application No. 55-173727).
However, many of them had the problem of increasing the number of steps during assembly due to the complicated structure, and also left problems with the dustproof property inside the bearing. Problems] ::□°The present invention eliminates these drawbacks of the conventional ones.
Finally, the anti-vibration rubber is used to prevent noise in the bearing of the rotary brush, and this anti-vibration rubber is used to improve the termite-proofing inside the bearing of the rotary brush. The purpose of this invention is to provide a vacuum cleaner vacuum cleaner equipped with anti-vibration rubber that is easy to use.

[Means for solving problems]

The configuration of the present invention for achieving the main objective will be explained using FIGS. 1 to 3 corresponding to the embodiments.
1 is a mouthpiece case, 2 is a mouthpiece tally brush, 3 is a
In the suction duct, 4 is a tabular joint, 5 is a wheel (large), and 6 is a wheel (small).

Further, 7 is a drive motor, 8 is a pulley (large), 9 is a pulley (small), 10 is a transmission belt, and 11 is a vibration isolating rubber.

Furthermore, 12 is a bearing support lip, 13 is a shaft stopper plate,
14 is a roller bearing, 15 is a shaft, 16 is a bearing plate, 17 is a tapered portion of anti-vibration rubber, 18 is a bearing stop plate, 19
is 7 lunges.

That is, a rotary brush 2 is installed inside the suction case 1, and this rotary brush 2 is connected to the drive motor 7.
It is something that rotates.

When the rotary brush 2 rotates and dirt is sucked into the suction case 1, the vibration-proof rubber peripheral edge 17 installed near the rotary brush 2 is moved between the bearing plate 16 and the shaft stopper plate 13. It works to prevent dirt from entering, and if the dust enters the vacuum cleaner body smoothly through the suction duct 3 and T-shaped joint 4, it becomes K.Also, if a fludge is protruded from the end face of the rotary brush 2, dirt will not enter further. can be prevented.

〔Example〕

The mouthpiece case is integrally equipped with a rotary brush 2.
A bearing support lip 12 is provided for supporting the
In addition, in order to move the mouthpiece smoothly, there are 5 wheels (large).
, and wheels (small) 6 are provided, and a T-shaped joint 4 is provided for connection to a vacuum cleaner body (not shown) provided with a fan motor.

The rotary brush 2 and the drive motor 7 are respectively provided with a pulley (large) 8 and a pulley (small). is hung on them.

The suction duct 3 is a passage for dust sucked from the suction port through the T-shaped joint and into the dust case.

Shaft t5 inside rotary brush 2
.

The end of the shaft has a notch K, which is engaged with the shaft stopper plate 13.

The shaft stopper plate 13 is supported by a bearing support lip 12 of the suction case l via a vibration isolating rubber 11 of the shaft stopper plate 13.

The vibration-proof rubber tapered portion 17 is installed near the rotary leap luff 2.

The roller υ bearing 14 is press-fitted into the bearing plate 16 and then fixed by the bearing retaining plate 18.
6 is removably engaged with the rotary brush 2.

That is, the rotary brush 2 is rotatably held via the rolling bearing 14.

On the other hand, when the rotary brush 2 rotates and dirt is sucked into the suction case l, the vibration-proof rubber tapered portion 17 installed near the rotary brush 2 is connected to the bearing plate 16 and the shaft stop plate. It works to prevent dirt from entering between the vacuum cleaner 13 and the dirt smoothly enters the vacuum cleaner body through the suction duct 3 and the T-shaped joint 4.

In the above embodiment, the tapered 9 portions of the vibration-proof rubber periphery were installed near the rotary brush, but no other parts were installed near the rotary brush.

It can be brought into direct contact with the rotary brush, and even in this case, the suction port can be configured accordingly and the same effect can be expected. Further, in this embodiment, a case has been described in which a motor is used as the rotary brush driving means, but the effect will not change in any way if other means other than the motor, such as an air turbine, are used. Furthermore, the cross-sectional shape of the tapered portion of the vibration isolating rubber of the bearing portion is the fourth.
, 5, as long as it is tapered 9, there is no difference in the effect even if the shape is different.

〔Effect of the invention〕

The effects of the present invention are as follows: C (1) With a simple structure, it is possible to prevent dust from entering the bearing part of the rotary brush, and it is possible to smooth the flow of dust.

(2) Not only is the structure simple, productivity is high, but also high reliability can be obtained.

(3) The sound of the rotary brush bearing can be prevented by the anti-vibration rubber, and this anti-vibration rubber can be used to improve the dust resistance inside the roller brush bearing.

(4) Since the periphery of the vibration-proof rubber is installed so as to cover the outer periphery of the rotary brush end face, the non-contact IIC rotates smoothly and quietly.

(5) Furthermore, since the flange is provided protrudingly on the end face of the rotary brush, it is possible to further prevent gore ξ from invading the inner crushing of the shaft.
