With reference to Fig. 2 and 3, the suction nozzle 100 of vacuum cleaner according to an embodiment of the invention comprises brush body 110, suction nozzle body 120 and extension coupling part 140.
One wheel pairs 121 is set at the rear end of each side of suction nozzle body 120 both sides, makes suction nozzle 100 to move on surface to be cleaned.Be formed with air intake duct 125 at the middle part of suction nozzle body 120, pass through described air intake duct from surperficial inhaled air to be cleaned.The air of brush body 110 enters pipe 114 and inserts in the front end 125a of air intake duct 125.Therefore, when brush body 110 rotated with respect to suction nozzle body 120 at a predetermined angle, air enters pipe 114 and air intake duct 125 forms the fluid connection each other.
Although do not illustrate among the figure, suction nozzle 100 can have the brush body 110 that forms as one with suction nozzle body 120.In this case, suction nozzle 100 does not have air and enters pipe 114, and the front end 125a of air intake duct 125 is directly connected to suction inlet 112, and wherein air and dust are inhaled into by described suction inlet from surface to be cleaned.The rear end of air intake duct 125 is connected to extension coupling part 140.
As shown in Figure 3, bypass channel 130 is formed on the upside of air intake duct 125.The effect of bypass channel 130 is to make to concentrate the pressure that is applied to suction inlet 112 to disperse, thereby reduces manipulation force and guide extraneous air directly not enter air intake duct 125 by suction inlet 112.As a result, extraneous air can enter air intake duct 125 by two flow channels.To be extraneous air and dust enter air intake duct 125 via the suction inlet 112 of brush body 110 for flow channel, and another flow channel is that extraneous air directly enters air intake duct 125 via bypass channel 130.
If extraneous air also enters air intake duct 125 by the another one flow channel except suction inlet 112, the pressure that then concentrates on the suction inlet 112 reduces.In other words, the brush body 110 of suction nozzle 100 and the seal force between the surface to be cleaned reduce.Therefore, the needed manipulation force that is used for mobile suction nozzle 100 of user reduces.At this moment, because the suction nozzle 100 suction dusts and the efficient of dirt and the pressure of suction inlet 112 are not proportional, so the bypass channel 130 that forms at the upside of air intake duct 125 can make the seal force between suction nozzle 100 and the surface to be cleaned reduce, and the dust collection efficiency of suction nozzle 100 remains on the level identical with the dust collection efficiency cardinal principle of the conventional suction nozzle 100 of vacuum cleaner 1.
Be formed with a plurality of through holes 136 at a part 126 places with double wall 131 corresponding air intake ducts 125.So extraneous air enters space between air intake duct 125 and the double wall 131 via the opposite side 132a in described space and 132b, then enters air intake duct 125 via a plurality of through holes 136.In addition, Sound-absorbing member 133 can be placed by the place, space between air intake duct 125 and double wall 131, makes and can reduce the air suction and noise that is produced when extraneous air enters air intake duct 125 via bypass channel 130.Sound-absorbing member 133 can have with it can cover all a plurality of through hole 136 the same big sizes.Porous material (for example, sponge etc.) can be used as Sound-absorbing member 133.
In the above description, the space between double wall 131 and the air intake duct 125 has unlimited opposite side 132a and 132b; Yet this should not be counted as restriction.Space between double wall 131 and the air intake duct 125 can have open side and closed side according to the structure of suction nozzle 100.
The air suction and noise that produces in order to reduce when extraneous air is inhaled into air intake duct 125 can be provided with noise and reduce passage 137 in bypass channel 130.Described noise reduces passage 137 and has bending flow channel for several times.In other words, noise reduction passage 137 is designed such that the flow direction of extraneous air is changed for several times.For example, noise reduces passage 137 and forms the zigzag shape, and the feasible direction of motion that reduces the extraneous air of passage by described noise changes for several times.When extraneous air reduced passage 137 by bending noise for several times, the flow rate of extraneous air reduced and has reduced the air suction and noise of extraneous air.
In suction nozzle 100 according to the vacuum cleaner of present embodiment, form air intakes 138 at suction nozzle body 120 and brush body 110 regional 119 places connected to one another, wherein extraneous air enters noise via described air intake and reduces passage 137.In other words, as shown in Figure 2, extraneous air enters noise reduction passage 137 via the zone 119 that suction nozzle body 120 is connected on the brush body 110.
In Fig. 4, arrow B 1, B2 and B3 illustrate the extraneous air that enters bypass channel 130 via air intake 138, and wherein said air intake is formed at 119 places, zone that suction nozzle body 120 and brush body 110 are linked together.Noise is set between air intake 138 and bypass channel 130 reduces passage 137, so that make the flow direction of extraneous air change 90 degree.Therefore, when the extraneous air that enters via the air intake 138 between suction nozzle body 120 and the brush body 110 reduced passage 137 by noise, the noise of described extraneous air reduced, and then extraneous air enters bypass channel 130.
Fig. 5 can be used in the schematic diagram that reduces another example of passage 137 ' according to the noise in the suction nozzle 100 of the vacuum cleaner of the embodiment of the invention for explanation.
With reference to Fig. 5, noise reduces passage 137 ' and forms the zigzag shape, and has the air intake 139 at the upper surface 120a place that is formed at suction nozzle body 120.Therefore, extraneous air C enters noise reduction passage 137 ' via the air intake 139 of the upper surface 120a of suction nozzle body 120.
Reduce in the passage 137 ' at noise, the flow direction of extraneous air C changes 180 degree for several times, makes the flow rate of extraneous air C reduce.If the flow rate of extraneous air C reduces, the air suction and noise that produces when then extraneous air C enters bypass channel 130 reduces.
Be provided with extension coupling part 140 in the rear end of suction nozzle body 120, suction nozzle body 120 is connected to (as shown in Figure 1) on the extension 20.Described suction nozzle body 120 and extension coupling part 140 are provided in rotation each other on the air intake duct 125.

On the other hand, as shown in Figure 4 arrow B 1, B2 and B3, some extraneous airs are via in the direct inhale pipe 125 of bypass channel 130 quilts of the opposite side place of air intake duct 125 upsides formation.In other words, some extraneous airs are inhaled into noise reduction passage 137 (shown in arrow B 1) via the air intake 138 of the formation of join domain 119 places between suction nozzle body 120 and brush body 110.When reducing passage 137 by noise, the moving direction that extraneous air enters air intake 138 changes, and the flow rate of following described extraneous air reduces (shown in arrow B 2).If the flow rate of extraneous air has reduced, then air suction and noise reduces.
The air that reduces passage 137 by noise enters Sound-absorbing member 133 via the sidepiece 132a of bypass channel 130.Air by Sound-absorbing member 133 enters air intake duct 125 (shown in arrow B 3) via a plurality of through holes 136 that form at air intake duct 125 upsides 126 places.Sound-absorbing member 133 is made by the porous material such as sponge, makes that the flow rate of air reduces once more when air passes through Sound-absorbing member 133, and then air suction and noise further reduces.
As mentioned above, if some extraneous air B1 enter air intake duct 125 via the flow channel that is different from suction inlet 112, wherein extraneous air A enters air intake duct 125 via described suction inlet, and the pressure that then is applied to the middle part (that is the center of suction inlet 112) of brush body 110 reduces.When the pressure at suction inlet 112 centers that are applied to brush body 110 reduced, the seal force between brush body 110 and the surface to be cleaned reduced.Therefore, compare with the conventional suction nozzle 10 of vacuum cleaner 1, the user can more handy suction nozzle 100.
In addition, because extraneous air reduces passage 137 via noise and Sound-absorbing member 133 enters air intake duct 125, so reduce when extraneous air is inhaled into the air suction and noise that is produced when passing bypass channel 130.
The extraneous air that enters air intake duct 125 via bypass channel 130 flow to body of dust collector 40 by extension 20 together in company with extraneous air, wherein said extraneous air be subjected to fan-motor assembly 43 suction effect and enter air intake duct 125 via the suction inlet 112 of brush body 110.
The dust and the dirt that enter body of dust collector 40 are separated from extraneous air by dust collect plant 41, and then the air of cleaning is discharged to outside the body of dust collector 40.
In order to confirm that the inventor has measured efficiency of dust collection, seal force and the noise according to the conventional suction nozzle 10 of the suction nozzle 100 of the vacuum cleaner of the embodiment of the invention and vacuum cleaner 1 according to the performance of the suction nozzle 100 of the vacuum cleaner of the embodiment of the invention.The result is as shown in form 1:
| The test sequence number | Efficiency of dust collection | | Noise | |
| 1 | Identical substantially | Reduce 3N | Identical substantially | |
| 2 | Identical substantially | Reduce 3N | Identical substantially | |
| 3 | Identical substantially | Reduce 2N | Identical substantially |
At this, three suction nozzles 100 according to the vacuum cleaner of the embodiment of the invention are measured.Noise is to measure at cleaning carpet and when suction nozzle 100 is operated and compare with the noise of conventional suction nozzle 10.Efficiency of dust collection and seal force are to measure when cleaning carpet and compare with the efficiency of dust collection and the seal force of conventional suction nozzle 10.
According to The above results, according to suction nozzle 100 has and conventional suction nozzle 10 is identical substantially the efficiency of dust collection and the noise of the vacuum cleaner of the embodiment of the invention.In addition, compare, on average reduce 2.7N according to the seal force of the suction nozzle 100 of the vacuum cleaner of the embodiment of the invention with conventional suction nozzle 10.In other words, according to the level that suction nozzle 100 remains on efficiency of dust collection and noise and conventional suction nozzle is identical substantially of the vacuum cleaner of the embodiment of the invention, but seal force has reduced.
With regard to regard to the suction nozzle of the vacuum cleaner of the embodiment of the invention, noise is identical substantially with conventional suction nozzle with efficiency of dust collection, but seal force is less than conventional suction nozzle.Therefore since according to the manipulation force of the suction nozzle needs of the vacuum cleaner of the embodiment of the invention less than traditional suction nozzle, this vacuum cleaner is easier to be cleaned so the user uses.
