Abstract

PURPOSE:To provide the suction means for a vacuum cleaner having a large effective opening area at the time of suction even if the means has a brush for sweeping in the central part of a suction port. CONSTITUTION:A partition plate 3 having the brush 5 for sweeping is freely oscillatably mounted at the position where the suction port 4 in the suction means body 2 is bisected to the two opening regions 4a, 4b. This partition plate oscillates to close the opening region on the rear side of a progressing direction at all times at the time of sweeping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner suction tool which is used by being connected to a suction tube of a vacuum cleaner.

[0002]

2. Description of the Related Art A suction tool for a vacuum cleaner that has been generally used in the past has a brush for cleaning around a suction port,
This brush is configured to collect dust and suck it through the suction port. In this case, most of the dust will be swept up in the forward direction of the brush, but this position hits the outside of the brush when viewed from the suction port, so dust that is located outside is sucked in through the brush. Therefore, there is a drawback that the suction efficiency is poor.

Therefore, in order to improve the suction efficiency, a brush is provided in the center of the suction port at a position that divides the suction port into two parts, and no matter which side of the brush dust is collected, the dust is sucked in. It is desirable to keep it in the mouth opening area, but most of the dirt is sucked in from the opening area on the front side in the direction of movement of the brush, and little is sucked from the opening area on the back side of the brush. Therefore, there is a problem in that the effective opening area is extremely smaller than the total opening area of the suction port, and the suction force cannot be effectively used.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to provide a brush for cleaning in the center of the suction port,
To obtain a suction tool for a vacuum cleaner having a large effective opening area during suction.

[0005]

In order to solve the above problems, according to the present invention, a sweeping brush is provided at the lower end at a position where the suction port of a suction tool body detachable from a suction tube of a vacuum cleaner is divided into two parts. There is provided a suction tool for a vacuum cleaner, in which a partition plate provided is attached so as to be swingable by a sweeping operation and capable of alternately closing an opening region divided into two portions of a suction port by swinging.

[0006]

The above-mentioned suction tool is for reciprocating on the floor surface back and forth or left and right, so that the brush at the lower end of the partition plate collects dust and sucks it from the suction port.

At this time, the partition plate oscillates due to the resistance force of the brush at the time of sweeping and alternately abuts against the left and right side walls of the suction port, so that the brush of the opening area divided into two parts of the suction port To close the opening area on the rear side in the direction of travel,
The opening area on the front side in the advancing direction of the brush is always in a large open state, and dust is sucked through this opening area.

As a result, even if a brush for sweeping is provided in the center of the suction port, a large effective opening area during suction is always secured, and the suction efficiency of dust is very good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The suction tool 1 of the embodiment shown in FIGS. 1 and 2 is of a type such as a broom that collects dust while sweeping it.
A partition plate 3 for sweeping is swingably attached to the inside of a main body 2 of a suction tool made of synthetic resin which is configured to be detachably attached to a suction pipe (not shown) of a vacuum cleaner.

The suction tool body 2 has a flattened and flat shape like a bunch of brooms, and has an elongated suction port 4 at its tip (lower end), and the suction port 4 is wide. The partition plate 3 is attached at a position where the partition plate 3 is divided into two parts.

The partition plate 3 has a sweeping brush 5 protruding from the suction port 4 at the lower end, which collects dust by the brush 5, and a spindle 6 provided at the upper end of the partition plate 3. 3 is pivotally supported by the suction tool main body 2, and as shown in FIG.
The tilting force of the suction tool 1 causes the suction tool 1 to tilt rearward with respect to the support shaft 6 by its resistance force. Four
Of the two divided opening areas 4a and 4b, the opening area located on the rear side in the traveling direction is closed. At the lower end of the suction tool body 2, a brush, an elastic member such as rubber, a comb-shaped slit, or the like having an appropriate length can be provided so as to surround the suction port 4.

As shown in FIG. 3, the suction tool 1 having the above-described structure is reciprocated in the left-right direction (width direction) on the floor surface 7 so that the floor surface 7 is moved by the brush 5 at the lower end of the partition plate 3. The upper dust is swept and sucked from the suction port 4.

At this time, the partition plate 3 swings around the support shaft 6 due to the resistance force of the brush 5 at the time of sweeping, and the lower end portion thereof alternately abuts the left and right side walls 2a and 2b of the suction port 4. As a result, the opening areas 4a, 4 of the suction port 4 are divided into two.
Of b, the opening region located on the rear side in the traveling direction of the brush 5 is always closed. That is, when the suction tool 1 moves in the direction of the arrow A, the partition plate 3 tilts as shown by the solid line, and the lower end thereof abuts the side wall 2a of the suction port 4 on the rear side in the traveling direction to open the rear side opening. When the region 4a is closed and the suction tool 1 moves in the direction of the arrow B, the partition plate 3 tilts as shown by the chain line, and the lower end of the partition plate 3 abuts on the opposite side wall 2b to open the other opening region 4b. Close. Therefore, the opening region 4a or 4b located on the front side in the traveling direction of the brush 5 is always in a large open state, and dust is efficiently sucked through this opening region.

In the above embodiment, a suction tool of the type that moves left and right like a broom to suck and collect dust is shown. You can also do it.

[0015]

As described above in detail, according to the present invention, a partition plate having a sweeping brush at the lower end is swingably attached to a position where the suction port of the suction tool is divided into two parts. At this time, since the partition plate is configured to swing to close the opening area on the rear side in the advancing direction of the brush among the two opening areas, only the opening area on the front side in the advancing direction of the brush where dust is collected is collected. It is possible to keep the large opening at all times and efficiently suck dust through the opening area.
