The specific embodiment
The present invention relates to a kind of suction nozzle 1 of dust catcher.This suction nozzle has a tube connector 2 that is connected with a unshowned main body of dust collector, and main body of dust collector has one can produce the fan motor that sucks air stream.
Tube connector 2 leads to suction nozzle base plate 11 places that contact with ground 4 to be cleaned by a tube connector 3.This tube connector 3 leads on the suction passage.These suction passages are roughly along the shape of suction nozzle, so that optimize suction efficiency.Shown in the example of triangle suction nozzle in, the suction passage part shown in the dotted line is extended along two sides 5,6 that form the suction nozzle tip, and extends to after the suction nozzle core converges in the described suction nozzle tip.
According to an important characteristic of the present invention, the angle part that forms the suction nozzle tip has an open front 7, is used to guarantee the suction on a direction substantially parallel with surface to be cleaned.
In addition, in an illustrated embodiment, suction nozzle has some and rotates the brush packed up that pedal 8 starts by one.Can touch pedal 8 at case 12 places of suction nozzle.In this embodiment, the case of suction nozzle mainly only has function attractive in appearance and the protection environment.
In fact, the internal structure that suction passage is partly realized during on the one hand by moulded floor is closed, as along the edge and lead to the part of the suction passage of opening 7, also close in addition by a upper parts 14, according to this embodiment, upper parts 14 is observation districts that realize by a transparent triangle part that is added on the base plate.
These characteristics make can observe surperficial rubbish 16 in cleaning course.This zone can cover a place bigger than suction passage according to the shape of suction nozzle and/or suction passage, so that adjust the aiming to the ground refuse that will remove.
In addition, viewing area has the effect of magnifying glass owing to lobed shape.Therefore the rubbish of observing under the district is exaggerated, thereby has improved the observation for the treatment of the clean surface.
Observe and just be preferably triangle, meet the global shape of suction nozzle in the zone of clean Surface, like this can be observing the district and connecting (easier manipulation) with the triangular shaped relevant use advantage of suction nozzle.
In order to observe, case has a simple opening in the place vertical with observing the district, and a transparent window that for example is made of plastics is perhaps arranged.
In addition, part 14 has a rear portion that links to each other with the end of tube connector 3.
Fig. 2,4 illustrates the upward view of suction nozzle.The base plate 11 of suction nozzle has several suction passages: the passage 20 that the edge of 19, one in passage substantially parallel with the edge 6 of suction nozzle and suction nozzle 5 is substantially parallel.These passages converge in the center 21 of suction nozzle.Passage 19,20 has open front, promptly in the vertical edge of base plate, is respectively 36 and 35, and these openings can side direction suck on the direction substantially parallel with surface to be cleaned.
A solid section 40 is finished triangle at the rear portion of suction nozzle, and this part 40 has two positions 42 that are used to be beneficial to the device that suction nozzle moves, and these devices can be the slide blocks of PTFE type, or wheel.
According to the present invention, thin slice 23 edge 5 from suction nozzle in this zone 21 extends to edge 6, therefore forms passage 22 behind a prepass 18 and, and prepass 18 leads to the tip of suction nozzle by open front 7.This thin slice 23 has a zone 24, is provided with known wire fabric of pulling out itself.
One of principal character of this thin slice 23 is to connect edge 5 and edge 6 as bridge, and regional 24 facing surfaces and last part 14 between a space is set.This thin slice is preferably parallel with the back 9 of suction nozzle.In fact, the most frequent moving direction of the direction of this thin slice and suction nozzle is vertical is highly significant.Yet because the position of tube connector 2 and connecting pipe 3, the main impeller-hub guiding suction nozzle of suction nozzle is mobile along a direction " nature " vertical with back 9.
Can on an edge of passage 22, be provided with a second area 28 pulling out wire fabric, so as with have zone 24 symmetries of pulling out kind of thread elements.
In the same idea of ground fiber, passage 19,20 has some respectively in suction passage, respectively from the edge 5 and the tiny scraping blade 46 and 45 that extends to the direction at another edge of edge 6 in useful effect.According to the example that proposes, these scraping blades are fixed, and stretch out from the lower plate of suction nozzle, and extend on the distance near a half width of passage substantially parallel with back 9.In addition, the gap between each little scraping blade is not dark, and has edge limited towards the inclination of suction passage by one, so that farthest limit the zone that rubbish may be blocked.
Base plate 11 also has position 25,26 (see figure 3)s that are used for packing up brush 55,56,57 (seeing Fig. 2,4), and these brushes are advantageously along the edge of suction passage.
During work, suction nozzle preferably moves on ground to be cleaned 4 along a direction vertical with back 9, and the user points to zone to be cleaned to suction nozzle, in addition unconsciously the tip of suction nozzle as guiding.Owing to have open front 7 in the suction nozzle tip, maximum rubbish can be inhaled into, and need not take off suction nozzle in order to collect rubbish.
Then, these rubbish pass through from having the thin slice 23 of pulling out kind of thread elements along direction F.Rubbish is drawn towards main body of dust collector then, leaves suction nozzle by tube connector 3.Observation district 14 can control some rubbish and be not plugged in the thin slice place.
Hang over the line on ground and the effect of pulling out kind of thread elements that fiber is subjected to thin slice 23, the advantage of thin slice is that its edge is two suction passages 18 and 22.No matter suction nozzle still moves forward backward, in both cases, in the motion of suction nozzle, after pulling out the effect of kind of thread elements, following once suction immediately to ground.
In addition, pull out line thin slice 23 in impeller-hub the location and the aiming of suction nozzle can implement that the user wishes effectively pull out the line action.
In addition, when suction nozzle is mobile backward, having the second area 28 of pulling out kind of thread elements can produce two at this moving direction and follow the process that acts on ground that once sucks: the once effect that kind of thread elements is carried out of pulling out by zone 28, follow the once suction of passage 22 then, another time is the effect that kind of thread elements is carried out of pulling out by thin slice 23, follows the once suction of passage 18 then.This double action can improve the suction nozzle to be cleaned lip-deep fiber on the moving direction and the collection efficiency of the end of a thread backward, because when suction nozzle is mobile backward, the user has the trend of lifting suction nozzle, then opposite when moving forward, the user has the trend of pressing suction nozzle earthward, and this has improved equally by pulling out kind of thread elements removes the efficient of fiber and the end of a thread.
Improve in the version at one of the present invention, the zone 28 and 24 of pulling out kind of thread elements is made of some aspectant inclination hairs, and for two zones, the inclination of hair is towards passage 22.When going, pull out kind of thread elements 28 and tangle hair, be sent to passage 22 discharges and pull out kind of thread elements 24 discounts, when returning, pull out kind of thread elements 24 and tangle hair, discharge hairs and pull out kind of thread elements 28 to same passage 22.
In addition,, the kind of thread elements of pulling out of two differing heights can be set, they are located on the clinoplain in order to overcome the depth disparity between coming and going.Can make the position of pulling out kind of thread elements adapt to most commercial velvet carpet like this, the go deep into degree of suction nozzle on these velvet carpets is not constant, on quite close or curling velvet carpet, the deep degree of suction nozzle not more sparse " bunch " dark on the formula velvet carpet.
In addition, in some cases, pull out kind of thread elements 24 and do not hang fiber and/or discharge a bundle fiber, anterior suction area can suck these fibers, avoids on these rubbish stand-downs.
