Description

Inhaler width control device of vacuum cleaner {A SUCTION DEVICE FOR AN ELECTRIC VACUUM CLEANER WHICH CAN REGULATE THE WIDTH}

The present invention relates to a vacuum cleaner inhaler to solve the inconvenience that can not be increased or reduced depending on the purpose of the vacuum cleaner used to clean the floor, the suction extension and the reduction motor at both ends of the inhaler In order to facilitate the cleaning of large and narrow places as needed, the width can be widened when cleaning a large place, and the width of the inhaler can be reduced by adjusting the width adjusting frame that works with the reduction motor when cleaning a narrow place. It relates to a vacuum cleaner inhaler with a characteristic that can be cleaned.

In addition to the spacious living room, there are also narrow areas where the vacuum cleaner inhaler is fixed. The width of the vacuum cleaner is fixed so that the width of the inhaler needs to be large when cleaning a wide area, and the smaller one when cleaning under or around a table. I felt the necessity of not having a cleaner to increase and decrease the width of the inhaler was inconvenient.

The present invention aims to satisfy a necessity of a wide inhaler for cleaning a narrow place and a wide inhaler for cleaning a large place.

The present invention is a cleaner with a narrow inhaler is inconvenient to clean a large area, and a cleaner equipped with a wide inhaler is inconvenient to clean a small area, the width of the inhaler is required by installing a width adjusting frame and a deceleration motor inside the vacuum cleaner inhaler It can be adjusted immediately according to the, so that both large area and small area can be cleaned at the same time.

The present invention can be cleaned more conveniently because it can be cleaned at the same time by increasing and reducing the width of the inhaler in a wide area and narrow area with a single cleaner.

Referring to the present invention in detail with reference to the accompanying drawings as follows.

As shown in FIG. 1, the inhaler width adjusting device of the vacuum cleaner according to the present invention includes a width adjusting frame 1, a reduction motor 2, a suction extension 6, a proximity sensor 9, 10, and a suction port distributed therein. It consists of (8,11,13).

The speed reduction motor 2 having a width adjusting frame on the inner central fixing shaft 17 of the inhaler housing 12, and in the center of the width adjusting frame 1, the bolt 3 and the nut 7 are fastened by a width It is provided to be rotatable separately from the direction of movement of the adjusting frame 1.

An extension control proximity switch 9 is provided at the edge of the width adjustment frame 1, and a reduction control proximity switch 10 is provided at the side of the reduction motor.

The width adjusting frame 1 is installed at the inner center of the inhaler housing 12, the left side of the inhaler housing is provided with a left suction extension 6, and the right side of the inhaler housing 12 has a right suction extension 5. ) Is provided. A central inlet 11 is provided at the center lower front of the inhaler housing, a left inlet 8 is provided at the lower front of the left suction extension 6, and a right inlet 13 is provided at the lower front of the right suction extension 5. Is provided. The expansion control proximity switch 9 interlocked with the reduction motor 2 and the width adjustment frame 1 operates the reduction motor 2 in response to the signal of the power switch 4 and moves according to the movement of the width adjustment frame 1. As the suction extensions 6 and 5 on both sides of the inhaler are extended, the expansion control proximity switch 9 is brought into close contact with the expansion control unit 14 so that the width expansion is stopped and the width of the inhaler is increased as shown in Fig. 19 of FIG. .

The reduction control proximity switch 10 interlocked with the reduction motor 2 and the width adjustment frame 1 operates the reduction motor 2 in response to the signal of the power switch 4 and moves according to the movement of the width adjustment frame 1. As the suction extensions 6 and 5 on both sides of the inhaler are reduced, the reduction control proximity switch 10 is in close contact with the reduction control unit 15 fixed to the nut 7 and the width reduction is stopped, thereby reducing the width of the inhaler.
