Abstract

PURPOSE:To high-efficiently recover cotton dust adhered to a brush after cotton dust is wiped by means of the brush by disposing a rotary brush, held such that the tip of a brush rotation of which is limited within 360' is brought into contact with a brush containing part, between suction ports on the front side and the rear side. CONSTITUTION:Rotation of a central rotary brush 5 at the front and in the rear of which suction ports 6 and 7 are arranged is limited within 360'. When reciprocation is effected in a state that a suction port l is slid over a floor surface to wipe off cotton dust on a floor cotton by means of the brush, the central rotary brush 5 is reversed and cotton dust heretofore wiped off is rubbed off by means of a brush containing part 14 located to the outer periphery thereof, namely, the cotton dust is sucked through a dust suction port 15, and dust is recovered with high efficiency. Further, by disposing a plurality of side brush parts 5a and 5b located to the outside in the longitudinal directions of the front and rear suction ports 6 and 7 and on the same lateral line or in a zigzagging manner, suction performance through side thereof is improved and dust near a wall is also sucked with high efficiency. Further, even when the suction port 1 is inclined longitudinally, brush parts 5, 1 5a, and 5b are brought into contact with a floor, whereby the damage of a floor by the suction port 1 is prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor suction port for a vacuum cleaner, and particularly to a structure of a floor suction port suitable for cleaning wooden floors.

[Conventional technology]

The floor suction port of conventional vacuum cleaners is
It is common to have a suction port in the center, one brush at the front and rear of the suction port, and rollers and wheels for running on the floor, as seen in No. 1.7. Ta. Alternatively, the 61st Utility Model was equipped with a single rotation roller at the suction port which improved running performance and operability. -10159, Utility Model No. 62-143
It had a structure similar to that described in No. 461 and Utility Model Application No. 6O-101 (No. '48).

[Problem to be solved by the invention]

In the above conventional technology, the methods include processing of cotton dust etc. wiped off with the brush, consideration to prevent the part without a protective function from touching the floor and damaging the floor when the suction spout is tilted forward, backward, left or right, and operation of the suction when the suction force is strong. There was a problem with the reduction in power or the lack of suction power for dust from the walls.

The present invention aims to improve the above-mentioned drawbacks, and provides a floor suction port for a vacuum cleaner that can efficiently collect cotton dust adhering to the brush after wiping the cotton dust with the brush part. It's there.

[Means to solve the problem]

In order to achieve the above purpose, the rotation of the central brush with suction ports arranged on the front and back is restricted within 360', and as the suction port slides on the floor surface, the brush wipes the cotton layer on the floor surface and reciprocates. When cleaning, the rotating brush in the center reverses and the cotton layer that has been wiped off is scraped off with the brush storage area on the outer periphery, and the cotton layer is immediately sucked in from the suction port to efficiently collect dust. This is what I did. Furthermore, by arranging multiple brush sections on the outside of the front and rear suction ports in the longitudinal direction, either at the same position or further forward and rearward, the suction performance from the sides is improved and dust from the walls is efficiently removed. Even when the suction port is tilted forward, backward, left, or right, the brush portion comes into contact with the floor to prevent the suction port from damaging the floor.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.
is composed of an upper case 2 and a lower case 3, and a bumper 4 is arranged on the outermost periphery to prevent scratches on furniture and the like.

A rotary brush 5 is disposed in the center of the lower case 3 so as to be able to swing back and forth within 360' within the brush housing 14, and when swinging back and forth, the tip of the brush is It is configured to abut against the inner wall of the brush storage section 14.

A plurality of dust suction ports 15 are also provided in a part of the inner wall.

Further, front suction ports 6 are provided on both sides of the rotating brush 5 in the longitudinal direction.
The front suction port 5 and the rear suction lower are slightly longer than the rotating brush 5, and the front suction port 5 and the rear suction lower merge inside and pass through the suction passage 8 to the upper case 2. A hose 10 on the side of the vacuum cleaner 9 which is rotatably held by the lower case 3. It is connected to a suction joint 12 that communicates with the extension pipe 11. Furthermore, the lower case 3 includes a side brush 5a located outside the front suction port 6 and at the same position as the front suction port or further forward.

A side brush 5b is arranged which is located as far back as the rear suction lower or further back.

According to this embodiment, (1) While the central rotating brush is moving toward the front side of the mouthpiece by back-and-forth operation of the mouthpiece, it moves counterclockwise to the rotation restriction position, and wipes off the cotton layer at the stop position; , When the mouthpiece is pulled back, the cotton layer is wiped off at the position where the rotating brush has moved to the clockwise rotation restriction position. When this rotating brush is reversed, the dust that adheres to the brush is rubbed against the inner wall of the brush housing, and
Suction can be efficiently carried out from the front or rear suction port, and the rotating brush can always be kept clean.

■Sight brushes are placed at the front, back, left, and right positions of the mouthpiece, so even if the mouthpiece is tilted forward, backward, left, or right during operation of the mouthpiece, the hard part of the base material that makes up the mouthpiece does not come into direct contact with the floor. , will not damage floors made of soft materials such as wooden floors. ■Since the side suction passage 13 is formed between the side brushes arranged on the left and right sides of the suction mouth, dust on the walls can be sucked in. ■In front of the front mouthpiece and behind the rear mouthpiece,
Since there are no members in contact with the floor surface, dust can be effectively sucked into the front and rear suction lowers without pushing the dust closer together. ■As the mouthpiece is moved only by a brush,
It can run silently even when running on wooden floors. ■Before and after,
Since the suction flow can be sucked from the left and right directions, the suction port can be operated with light force even when connected to a vacuum cleaner with a large suction force. ■For floor cleaning, it not only uses suction power, but also has the effect of wiping with a brush, and can be cleaned efficiently with light operating force.

〔Effect of the invention〕

According to the present invention, the central rotating brush, which is composed of suction ports at the front and rear, can move the dust wiping surface by reciprocating the suction port back and forth, and is securely fixed during the wiping operation, so that the brush can be used to wipe the dust. To obtain a floor suction port for efficient floor cleaning without adhering dust.
