With reference to Fig. 1, adopt according to an embodiment of the invention that the vacuum cleaner 100 of suction brush assembly 200 comprises the dust-absorbing element 110 that wherein has the vacuum source (not shown), the suction brush assembly 200 that is used for sucking by the suction force that vacuum source produced dust on the surface that will be cleaned, and be connected to suction brush assembly 200 will be directed to the extension path 120 in the dust-absorbing element 110 by the dust that suction brush assembly 200 sucks.Extension path 120 can comprise the extension connector 126 that is pivotally mounted on the suction brush assembly 200, extension 124 and the suction tube 122 that is connected to extension 124, described extension 124 is connected to extension connector 126 by an end, and an other end is connected to dust-absorbing element 110.
With reference to Fig. 2,3, comprise lower house 210, upper shell 250 and noise reduction unit 300 according to the suction brush assembly 200 of example embodiment of the present invention.
Because the existence of first and second suction inlets 211,212, suction force preferably is transferred to the sidepiece S of mid portion M and suction brush assembly 200 equably.That is, the air of the air of the carrying dust that sucks towards mid portion M at direction of arrow Q1 and the carrying dust that sucks towards sidepiece S in direction of arrow Q2Q3 can flow into suction brush assembly 200 equably.
Therefore, compare with the traditional suction brush assembly that only has a suction inlet on mid portion M, the pumping efficiency on the sidepiece S can be guaranteed.Equally, because the pumping efficiency on the mid portion M is enhanced, the surface that is cleaned can broaden.Although first and second suction inlets 211,212 have semi-circular shape in an embodiment of the present invention, described shape is not limited thereto.Suction inlet 211 can form different shapes with 212, for example ellipse and triangle.
In order to improve cleaning efficiency, first and second under sheds 216 and 217 and first and second dust channels 214 and 215 are formed in the lower house 210.Loam cake 230 can have first and second upper sheds 231,232.
First and second under sheds 216,217 are formed on the bottom of lower house 210, and its mode is that first under shed 216 tilts to the right, and second under shed, 217 relative dividing plates 213 tilt to the left side.
First and second under sheds 216,217 one-tenth rectangular areas form in this embodiment, and still, they can form with other shape, such as ellipse and triangle.Equally, the position can be considered the position of first and second suction inlets 211 and 212 and change.

The extraneous air that is directed scatters and is stacked on dust between first and second dust channels 214,215, comprises that the air of the carrying dust of the dust that is scattered is inhaled into first and second suction inlets 211,212 along direction of arrow F3 and F4 along first and second dust channels 214 and 215.Therefore, the dust between first and second dust channels 214 and 215 can be easy to be cleaned, and improves cleaning efficiency thus.
With reference to Fig. 2,4, upper shell 250 comprises path lid 220 and loam cake 230.The path lid 220 and the loam cake 230 that are separately positioned in this example embodiment can be integrally formed.
Particularly, the upper wall of access path 221 is by 220 formation of path lid, and the bottom of access path 221 and rear wall 210d form by lower house 210.
With reference to Fig. 2, loam cake 230 is connected to the lower house 210 on the path lid 220, forms the seal cavity in the suction brush assembly 200 thus.Loam cake 230 has first and second upper sheds 231,232 that are used for being connected with extraneous air, as mentioned above.Can be discharged to first and second under sheds 216,217 (Fig. 3) by seal cavity and by first and second upper sheds, 231,232 outer air that sucked.
Although first and second upper sheds 231 and 232 otch that are formed according to illustrated embodiment can use other number, shape and size, such as a plurality of through holes.Alternatively, shielding part or valve can be provided to first and second upper sheds 231 and 232, are used to flow into air to open 231,232 of first and second upper sheds.
With reference to Fig. 2-4, air outlet slit 210e is formed on the centre of the midfeather 210d of access path 221, and air outlet slit 210e has and can pivot and/or rotatably settle thereon extension connector 126 (Fig. 1).
Be collected at air outlet slit 210e at the air-flow from first suction inlet 211 and the carrying dust that on direction of arrow Q6, sucked from second suction inlet 212 on the direction of direction of arrow Q5.
When the air that sucks and accumulate in the carrying dust on the air outlet slit 210e by first and second suction inlets 211,212 is all discharged together by extension connector 126, because the air-swirl that the speed of air-flow increase and air-flow are produced when colliding each other mutually produces noise.Equally, the pressure of air-flow and rear wall 210d and direct collision may be made noise.
With reference to Fig. 2, access path 221 has noise reduction unit 300 to prevent such noise, and it comprises that first and second noises reduce rib 310,320 and first, second noise absorption part 330,340.
First and second noises reduce that parts 310 and 320 preferably relative access paths 221 are mutually symmetrical and can be by the plastic material manufacturings, such as propylene.Other the material such as glass, metal also can be used for noise and reduce rib 310,320.
Because first and second noises reduce rib 310,320 and construct in an identical manner, having only first noise to reduce rib 310 among Fig. 5,6 will illustrate below, be used to describe in detail first and second noises and reduce rib 310,320.
First noise reduces rib 310 is installed to air outlet slit 210e at direction of arrow R along the rear wall 210d of access path 221 the right.
This makes the air of carrying dust contact as much as possible with rear wall 210d, because the air of carrying dust may tilt to the rear wall 210d of access path 221, the while flow to access path 221 owing to the shape of the bending of access path 221 from first suction inlet 211.Therefore, reduce rib 310 by along rear wall 210d first noise being installed, noise can more effectively be prevented.
With reference to Fig. 5, the first noise absorption part 330 is inserted between the rear wall 210d that first noise reduces rib 310 and access path 221.
With reference to Fig. 2, it is that height H 2 on the direction of arrow R (promptly towards the right) reduces gradually that first noise reduces the mode that rib 310 is placed, and settles towards 211 bendings of first suction inlet.
First noise reduce rib 310 consider the height of path lid 220 and access path 221 rear wall 210d shape and by as above-mentioned structure, make things convenient for thus on access path 221 and install.In addition, the air of carrying dust can pass through access path 221, is subjected to reducing the littler resistance of rib by first noise.
Refer again to Fig. 5, first noise reduces rib 310 and comprises a plurality of first angling hole 310a, and the first angling hole 310a tilts with angle θ 1 relative vertical line on from first suction inlet 211 to the moving direction of air outlet slit 210e at the air that on the direction of arrow Q5, promptly carries dust.Herein, tilt angle theta 1 is greatly between 40 degree and 70 degree.
Described inclination has prevented to flow directly into the first angling hole 310a by the air of the carrying dust of access path 221.Particularly, when flowing through access path 221 on direction of arrow Q5, the air of carrying dust flows into the first angling hole 310a indirectly on direction of arrow Q8.In order to reach this purpose, angle θ 1 may be limited to distribution and the deviation that direction of arrow Q5 goes up the air of the carrying dust that flows.
It approximately is width W 1 between 0.5 to 1.0 times of distance D 1 between the first angling hole 310a that the first angling hole 310a has.By the width W 1 of the described first angling hole 310a, the air of carrying dust can partly be received.
With reference to Fig. 2,7, the first noise absorption part 330 has the height H 5 on the right that is reduced to air outlet slit 210e on direction of arrow R gradually, and towards 211 bendings of first suction inlet, otherwise to be mounted or to be positioned between the rear wall 210d that first noise reduces rib 310 and access path 221.
The first noise absorption part 330 has reduced at first to reduce the noise that rib 310 reduces by first noise once more, and is in this purpose, and porous material can be used to the first noise absorption part 330 such as sponge, common filter and foam.
Below, the relation that the first noise absorption part 330 and first noise reduce between the rib 310 will be illustrated.
But the first noise absorption part 330 for the present invention not necessarily.When the first noise absorption part 330 was omitted, first noise reduced the rear wall 210d that rib 310 can be directly connected to access path 221.Equally, other method such as screw and welding rather than bonding agent can be used to and be connected first noise and reduce the rib 310 and the first noise absorption part 330.
Reducing rib 320 with reference to Fig. 2,4, the second noises is mounted along the rear wall 210d of access path 221 (promptly to air outlet slit 310e the left side) on direction of arrow L.Second noise reduces parts 340 and is inserted into second noise and reduces between the rear wall 210d of rib 320 and access path 221.
The height H 3 that second noise reduces rib 320 to has on direction of arrow L (promptly to air outlet slit 210e the left side) descends gradually and towards 212 bendings of second suction inlet.
As above construct with the reason of settling second noise to reduce rib 320 and reduce the identical of rib 310 with first noise.
Second noise reduce rib 320 be included in air that direction of arrow Q6 went up, promptly carried dust from second suction inlet 212 to the moving direction of air outlet slit 210e on a plurality of second angling hole 320a of angle θ 2 relative vertical lines inclinations.Herein, tilt angle theta 2 is greatly between 40 degree and 70 degree.
Described inclination has prevented to flow directly into the second angling hole 320a by the air of the carrying dust of access path 221.Particularly, when flowing through access path 221 on direction of arrow Q6, the air of carrying dust flows into the second angling hole 320a indirectly on direction of arrow Q9.In order to reach this purpose, angle θ 2 may be limited to distribution and the deviation that direction of arrow Q6 goes up the air of the carrying dust that flows.
It approximately is width W 2 between 0.5 to 1.0 times of distance D 2 between the second angling hole 320a that the second angling hole 320a has.By the width W 2 of the described second angling hole 320a, the air of carrying dust can partly be received.
With reference to Fig. 2, the second noise absorption part 340 has on the direction of arrow L height H 6 that (promptly to air outlet slit 210e the left side) reduces gradually, and towards 212 bendings of second suction inlet, otherwise to be mounted or to be positioned between the rear wall 210d that second noise reduces rib 320 and access path 221.
The second noise absorption part 340 has reduced at first to reduce the noise that rib 320 reduces by second noise once more, and for this, porous material can be used to the second noise absorption part 340 such as sponge, common filter and foam.
Because rear wall 210d, second noise reduce parts 340 and second noise and reduce relation and rear wall 210d, the first noise absorption part 330 and first noise between the rib 320 and reduce identical between the rib 310, omission explanation herein.
