Abstract

The vacuum cleaner comprises a main body (1) wherein the motor unit and the control unit are placed; a hose (8) connected to said main body (1); a handle (2) to facilitate the user's handling, which consists of a hose inlet (3) where to the hose (8) is connected and a tube inlet (4); a tube (9) attached to the tube inlet (4); and a brush nozzle (18) placed on the handle (2). It also comprises an adaptor piece (10) which protects the bristles (20) of the brush nozzle (18) attached onto the handle (2) while the tube (9) is being connected or removed and prevents the brush nozzle (18) from being released off the handle (2) during use.

Description

The The present invention relates to a vacuum cleaner according to the preamble of claim 1, comprising a brush nozzle, which is attached to the handle.

vacuum cleaner comprise a main body, one flexible hose connected to the body and attached to one End is provided with a handle; and a pipe, one end of which attached to the handle and that is an effective recording and collection of wet and dry dust particles by attaching various accessories enabled at its other end. As an accessory become pipe nozzles, Textile nozzles, Brush nozzles etc. used. While the use of this accessory certain difficulties arise. These accessories will be at the mouthpiece of the pipe and / or the handle by the user at the time of Use appropriate. These accessories are actually either at the main body or in remote locations that are removed from the cleaning area, kept. this leads to at a loss of time and causes difficulties in use.

Some techniques have been developed to overcome this disadvantage. A vacuum cleaner according to the preamble of claim 1 is in U.S. Pat. No. 3,259,934 disclosed. In this case, the dust brush of the vacuum cleaner in a hollow portion which is provided on the handle, arranged movable. There are guide channels extending along the sides of this section, and buttons projecting from the guide channels are disposed on the ring supporting the brush. When the buttons are pressed, the brush moves in the body and thus the brush is held in the body by the handle when not in use.

The Object of the present invention consists in the realization of a Vacuum cleaner with a brush nozzle, the is arranged on the handle.

Of the Vacuum cleaner, which was realized to the above task to solve the present invention, is attached in the Drawing shown, show:

1 a general view of the vacuum cleaner;

2 a three-dimensional exploded view of the handle, the adjustment element and the brush nozzle;

3 a three-dimensional exploded view of the tube inlet, the adapter element and the dust brush;

The vacuum cleaner comprises: a main body ( 1 ), in which the motor unit, which realizes the suction effect, and the control unit are included, a handle ( 2 ), a hose ( 8th ) having a flexible structure that is interposed between the main body ( 1 ) and the handle ( 2 ), a pipe ( 9 ), the handle ( 2 ), and a cleaning head ( 13 ), with the pipe ( 9 ) connected is. The handle ( 2 ) contains at one end a hose inlet ( 3 ) and at the other end a tube inlet ( 4 ). The vacuum cleaner also contains certain accessories that are used during various cleaning operations position of the cleaning head ( 13 ) are used to clean different surfaces by placing them at the end of the tube ( 9 ). One of these accessories is the brush nozzle ( 18 ). The brush nozzle ( 18 ) according to this invention can be used by holding the handle ( 2 ) is attached, and is with bristles ( 20 ) to perform the cleaning function.

The vacuum cleaner is also equipped with an adjustment element ( 10 ), the bristles ( 20 ) of the brush nozzle ( 18 ) protects the handle ( 2 ) while the pipe ( 9 ) is connected or removed. The tube inlet ( 4 ) on the handle ( 2 ) contains three sections: the front section ( 5 ), on which the pipe ( 9 ), the middle section ( 6 ) on which the adaptation element ( 10 ) is fixed and the rear portion ( 7 ), where the brush nozzle ( 18 ) emotional.

The front section ( 5 ) has a width and a structure that allows the connection of the pipe ( 9 ) on the handle ( 2 ) allows. The rear section ( 7 ) comprises at least one guide channel ( 16 ), a parking stop ( 25 ) and a park well ( 17 ) at the end of the guide channel ( 16 ), a locking stop ( 26 ) and a blocking recess ( 15 ) adjacent to the inlet portion of the guide channel ( 16 ). In the middle section ( 6 ) is preferably a circular stop ( 24 ) arranged. A deepening ( 14 ) is between the rear portion and the circular stop ( 24 ) educated. The diameter of this depression ( 14 ) is equal to that of the front section ( 5 ), whereas the diameter of the rear portion ( 7 ) equal to the circular stop ( 24 ), which is in the middle section ( 6 ) is arranged.

The adaptation element ( 10 ) has a hollow cylindrical structure. Its diameter is larger than that of the front section ( 5 ), at the end of the handle ( 2 ), and is provided on its inner surface with preferably four claws. Two of these claws are preferably the front claws ( 11 ) and the other two are back claws ( 12 ). Furthermore, openings ( 23 ), which provide flexibility, to the adjustment element ( 10 ) and the front claws ( 11 ) and the hind claws ( 12 ) are between the openings ( 23 ) arranged. The distance between the front claws and the back claws ( 11 . 12 ) is equal to the width of the circular stop ( 24 ).

The brush nozzle ( 18 ) contains an end section ( 21 ) with the bristles ( 20 ) and a neck portion ( 22 ) at the back. Openings ( 23 ) which provide flexibility are at the neck portion ( 22 ) and locking projections ( 19 ) are on the inner surface of the brush nozzle ( 18 ) below the surface, between the openings ( 23 ) remains. The end section ( 21 ) is wider than the neck portion ( 22 ), the diameter of the neck portion ( 22 ) is greater than the diameter of the rear portion ( 7 ) at the inlet of the tube ( 9 ), the adaptation element ( 10 ) and the handle ( 2 ).

During the attachment of the brush nozzle ( 18 ) on the handle ( 2 ) gives the surface between the openings ( 23 ), at which the locking projection ( 19 ), and the locking projection ( 19 ) extends over the circular stop ( 24 ) so that it is in the guide channel ( 16 ), which is positioned along the surface, at the rear portion ( 7 ) and along the channel ( 16 ) emotional. When he park the car ( 25 ) located at the end of the guide channel ( 16 ) is reached, extends the locking projection ( 19 ) over the parking stop ( 25 ) and slides into the park well ( 17 ). In this state, the dust brush ( 18 ) in a passive position.

If the adjustment element ( 10 ) on the handle ( 2 ), first gives the surface between the openings ( 23 ), which the front claws ( 11 ), after and the front claws ( 11 ) move over the circular stop ( 24 ) and slide into the depression ( 14 ). Meanwhile, the Hinterklauen lie ( 12 ) on the circular stop ( 24 ) and at the same time the circular stop ( 24 ) in the gap between the front and rear claws ( 11 and 12 ). In this case, the adjustment element ( 10 ) on the handle ( 2 ) fixed. The pipe ( 9 ) is simply placed in the room due to the difference in diameter of the front section ( 5 ) and the adaptation element ( 10 ) is formed, and thus are the bristles ( 20 ) of the brush nozzle ( 18 ) in a passive position above the adjustment element ( 10 ) remains.

When the user the brush nozzle ( 18 ) in an active position, the pipe ( 9 ), the handle ( 2 ) is removed, and it is a force on the brush nozzle ( 18 ) exercised. As a result, the locking projection ( 19 ) in the park well ( 17 ) over the parking stop ( 25 ) and moves in the guide channel ( 16 ). As a result of this movement, the brush nozzle ( 18 ) on the adaptation element ( 10 ) and the locking projection ( 19 ) slides into the locking recess ( 15 ), while talking about the locking stop ( 26 ), with a rotational movement in the direction of the locking recess ( 15 ) executed by the user. As a result, the brush nozzle ( 18 ) in the blocking recess ( 15 ) and is available for use. Because in this position the brush nozzle ( 18 ) longer than the front section ( 5 ), which is arranged on the handle, the bristles ( 20 ) on the brush nozzle ( 18 ) be used actively and effectively. In this way, the brush nozzle ( 18 ) on the handle ( 2 ) be taken and the pipe ( 9 ) can be removed at the request of the user, and thus the brush nozzle ( 18 ) brought into an active position.
