Abstract
The present invention provides a suction nozzle of a vacuum cleaner used on floor enhancing a dust collecting effect by blowing intake air of a turbine on a floor surface. When cleaning is performed by operating a vacuum cleaner, air flows from an air intake port to the turbine to rotate the turbine. A rotary brush rotates by synchronizing with the rotational force. At the same time, intake air rotating the turbine becomes air flow, is led to an intake air flow passage including a turbine chamber formed by the rotary brush and a partition wall between the turbine and a front surface of the rotary brush and is blown from a plurality of intake blowoff ports provided in the vicinity of the floor surface of the partition wall on the front surface of the rotary brush to the floor surface. By blowing air to the floor surface of a suction port, dust on the floor surface and a carpet is flung up, and air is passed through a bent joint and is sucked into a cleaner main body together with dust scraped up by a blade of the rotary brush.

The specific embodiment
Below, referring to figs. 1 through Fig. 5 the dust absorption nozzle for floor of electric dust collector of the present invention is described.Fig. 1 is the vertical view of dust absorption nozzle for floor, Fig. 2 is the vertical view that dust absorption nozzle for floor is removed upper case, Fig. 3 is the transverse sectional view of dust absorption nozzle for floor along the A-A line, Fig. 4 is the longitudinal sectional view of dust absorption nozzle for floor central part, and Fig. 5 is the longitudinal sectional view of the turbine portion in the dust absorption nozzle for floor body.
In Fig. 1 and Fig. 2, upper case 1 cover on dust absorption nozzle for floor above, be equipped with in the place ahead of lower case 2 and side and be used for the crashproof frame 3 of buffering collision of closed, the wheel 5 of being convenient to mobile cleaner head also is installed.Be provided with the crooked joint 4 of the dust that sucks from suction inlet 6 being delivered to dust collector host (not shown) by the suction air-flow at its rear.
In suction inlet 6, be provided with rotating brush 7, constitute rotation support freely, be connected with rotating brush 7 formation at the inboard turbine 9 of bearing 8 by the bearing 8 that supports two-wheeled.In the periphery of rotating brush 7, the blade 13 with soft flexible is entrenched in to have along in the embeded slot of the rotating brush matrix that forms continuous embeded slot on the helix of long axis direction.
Cover rotating brush 7 and turbine 9 and can the upper case 1 of independent dismounting on, offer and turbine 9 opposed air entries 12.In addition, be provided with next door (dividing plate) 10, the air-breathing stream 11 that comprises the impeller unit room formed mutually with rotating brush 7 separate in the front of rotating brush 7, turbine 9 and rotating brush 7.Be formed with on the lower case 2 the water conservancy diversion stream 14 that imports crooked joint 4 from suction inlet 6 by the air behind the rotating brush 7.
Fig. 3 is the transverse sectional view of dust absorption nozzle for floor along the A-A line, the position on the close ground in set next door 10 between the front of rotating brush 7 and turbine 9 and rotating brush is provided with a plurality of handles and is inhaled into the indoor air-breathing air-breathing blow-off outlet 15 that blows to ground by stream 11 of turbine.And, shown in the longitudinal sectional view of the dust absorption nozzle for floor central part of Fig. 4 like that, the front end of the air-breathing blow-off outlet 15 of next door 10 is formed on the rake on the direction that blows to ground.
Fig. 5 is the longitudinal sectional view of turbine portion, and the air-breathing formation air stream 16 that the air entry 12 that expression is offered from upper case 1 sucks after making turbine 9 rotations, flows to the state of the stream 11 that comprises the impeller unit room.
According to such formation, when the startup electric dust collector carried out dust suction, air flowed to turbine 9 from air entry 12 and makes turbine 9 rotations.Rotating brush 7 rotates synchronously with this revolving force, has swept ground dust by the blade 13 of this rotating brush 7, makes this dust along with the airflow smooth ground that sucks from the water conservancy diversion stream 14 at rotating brush 7 rears is inhaled in the dust collector host by crooked joint 4.
Simultaneously, make the air-breathing formation air stream 16 of turbine 9 rotations, be imported into by the 10 formed air flow circuits 11 that comprise the impeller unit room of the next door between rotating brush 7 and turbine 9 and rotating brush 7 fronts, and blow to ground from 3 air-breathing blow-off outlets 15 of the close surface location in the next door 10 that is arranged on the rotating brush front.At this moment, because the front end of air-breathing blow-off outlet 15 is formed on the tilted shape that blows on the direction of ground, so improved the drifting dust effect that blows to ground.
By air being blowed to the ground under the air entry 6, dust on ground and the carpet is blown afloat, and this dust and the dust of having been swept by the blade 13 of rotating brush 7 together are inhaled in the dust collector host along with crossing crooked joint 4 from the air communication of water conservancy diversion stream 14 suctions at rotating brush 7 rears.
In this embodiment,, be not limited thereto, also can only be arranged on the end in the dust absorption nozzle for floor though be that two ends in dust absorption nozzle for floor are provided with above-mentioned turbine and air entry.In addition, air-breathing blow-off outlet 15 also is not limited to 3, can suitably select any number more than 1.
As mentioned above, the dust absorption nozzle for floor of electric dust collector of the present invention, since the air-breathing importing of the turbine that is used to drive rotating brush by the formed air flow circuit that comprises the impeller unit room in next door between rotating brush and turbine and rotating brush front, make it blow to ground from a plurality of air-breathing blow-off outlets, so, can blow afloat the dust on ground and the carpet, and make these dusts and the dust of having swept by the blade of rotating brush together be inhaled into dust collector host, can improve pick-up performance.In addition, by the front end of air-breathing blow-off outlet 15 is formed the tilted shape that blows on the direction of ground, can improve the drifting dust effect that blows to ground.
