Description

[Detailed Description of the Invention] This invention relates to a carpet cleaning suction port for a vacuum cleaner.

Conventionally, this type of suction port body is used for carpet cleaning, so it is equipped with a rotating brush that lathers detergent on the carpet surface, but this rotating brush is also used for cleaning. It is customary that

In conventional brush bristles, the bristles planted on the outer periphery of the shaft of the rotating brush are formed in a spiral, but the spiral direction is set to move detergent or dust from the center to the sides. has been done.

Therefore, the detergent can be supplied from one place in the center, but there is a drawback that bubbles protrude on both sides of the suction port during carpet cleaning, making it difficult to distinguish between cleaned areas and unwashed areas. There is a problem that even if you are careful about cleaning, the remaining parts will come out.

In addition, when cleaning, the suction port that sucks in dust is usually formed in the center, but if the dust is guided to the sides by the rotating brush, the dust collection efficiency will decrease. have.

This idea was developed in view of these points, and it is a carpet for vacuum cleaners that can reliably clean the entire surface of the carpet during cleaning, and that can also reliably collect dust during cleaning. The purpose is to obtain a cleaning suction port body.

This idea is based on the brush storage chamber formed in the suction port body.
A rotating brush that is driven by a vacuum cleaner is attached, and brush bristles that guide detergent from the sides to the center are spirally formed on the shaft of the rotating brush, and are arranged on both sides of the upper part of the brush storage chamber. The present invention is characterized in that a detergent dripping brush is provided which forms detergent dripping portions and is positioned below these detergent dripping portions and comes into contact with the brush bristles.

Therefore, the bristles of the rotating brush are spirally formed to guide dust or detergent on the floor from the sides to the center, so the detergent protrudes from the sides of the suction port when cleaning carpets. Because there is no cleaning, the areas that have not been cleaned are clear, so there is no area left to clean, and when cleaning, dust is collected in the center, which greatly improves suction efficiency. It is configured as follows.

An embodiment of this invention will be described based on the drawings.

First, a downwardly opening brush storage chamber 2 is formed at the front of the suction port main body 1, and a support wall 4 having a suction port 3 formed in the center is formed at the rear of the brush storage chamber 2.

A connecting pipe 5 connected to a vacuum cleaner (not shown) is rotatably attached to the rear of the suction port main body 1, and an air passage 6 is formed between the rotating pipe 5 and the supporting wall 4. .

A fan 7 that is rotated by the suction airflow is provided in the air passage 6, and the fan 7 is connected to rotate a rotating brush, which will be described later, by an interlocking mechanism (not shown).

Further, a bypass hole 8 is formed between the fan 7 and the support wall 4.

Furthermore, a slit 9 is formed in the supporting wall 4 and extends upwardly to a depth that penetrates the suction port 3.

Next, in the brush storage chamber 2, there is provided a rotating brush 10 whose both ends are pivoted.

This rotating brush 10 has a shaft portion 11 having a predetermined diameter and a shaft portion 1 having a predetermined diameter.
The brush bristles 12 are made up of brush bristles 12 that are flocked on the outer peripheral surface of the rotary brush 10, and the bristles 12 spiral in a direction that guides dust or detergent on the floor from the sides to the center by the rotation of the rotating brush 10. Hair has been transplanted.

A detergent guiding portion 13 having a groove shape is formed in the upper part of the brush storage chamber 2. As shown in FIG.

The detergent guiding portion 13 has inclined surfaces 14 that slope downward from the center toward the sides, and detergent dripping portions 15 shaped like thank-yous are formed at the ends of these inclined surfaces 14.

Below these detergent dripping parts 15 is the rotating brush 10.
A detergent dripping brush 16 is attached which is in contact with the bristles 12 of the detergent dripping brush 16.

Next, 17 is a detergent container in which detergent is stored, and this detergent container 17 is detachably attached to the suction port main body 1.

An injection port 18 for injecting detergent is formed on the upper surface of the detergent container 17, and a partition plate 19 that fits into the slit 9 and the detergent guiding portion 13 are formed on the bottom surface of the detergent container 17.
A nozzle 20 that fits into the center of the detergent nozzle 20 is provided, and an open/close switch 21 for opening and closing the detergent nozzle 20 is provided above the detergent nozzle 20.

In addition, when cleaning, the bypass hole 8 and the detergent dripping part 1 are
5 and the upper part of the slit 9 are closed by a lid (not shown).

In such a configuration, the detergent container 17 is attached to the suction port main body 1.
When installed, the suction port 3 is closed by the partition plate 19.

When the vacuum cleaner is driven in this state, the airflow that rotates the fan 7 is sucked through the bypass hole 8.

Since the fan 7 rotates in this way, the rotating brush 1
0 is also driven, and the detergent nozzle 20 is activated by the open/close switch 21.
When opened, the detergent flows down into the detergent guide section 13 and drips onto the detergent dripping brush 16 from the detergent dripping section 15.

As a result, the detergent is evenly supplied to the bristles 12 of the rotating brush 10, and the supply portions are at both ends.
Due to the spiral state of the brush bristles 12, the bristles are supplied to the carpet surface and guided to the center.

Therefore, when the suction port main body 1 is moved, detergent bubbles are left within the width of the rotating brush 10, and since there are no bubbles in the areas that are not cleaned by the rotating brush 10, there is no possibility that they will be left behind after cleaning. .

Next, when cleaning is performed, the detergent container 17 is removed, which opens the suction port 3 and effectively collects dust in the brush storage chamber 2.

However, due to the rotation of the rotating brush 10, dust is collected in the center of the brush storage chamber 2, and since the suction port 3 is formed in this center, the dust collection efficiency is extremely high.

In the above embodiment, the detergent guide portion 13 is formed in the suction port body 1, but the detergent container 1
Two detergent outlet ports may be formed in the detergent dripping brush 16 so as to directly face the detergent dripping brush 16.

In this design, as mentioned above, the brush bristles on the rotating brush have a spiral shape that guides dust etc. from the sides to the center, and the detergent dripping part and the detergent dripping brush are provided on both sides, so that Since the detergent does not protrude to the side of the suction port during cleaning, the areas that are cleaned and the areas that are not cleaned can be clearly distinguished, making it possible to clean the entire surface without leaving anything behind. Even when used for purposes, it has effects such as extremely high dust collection efficiency.
