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.Be shaped as leg-of-mutton shown in the example of suction nozzle, the suction passage part shown in the dotted line is extended along two sides 5,6 that form the suction nozzle tip, and after converging at the suction nozzle core, extends in the tip of described suction nozzle.A back 9 connects side 5,6.
In addition, 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 retractable brush 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 has function attractive in appearance and the protection environment.
In fact, suction passage is closed by an internal structure that partly realizes during by moulded floor on the one hand, as along the edge and lead to the suction passage part of opening 7, also close in addition by a upper parts 14, according to embodiment, part 14 is observation districts that realize by a transparent triangle part that is added on the base plate.
These characteristics can be observed the rubbish on surface 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 clean Surface.
Fig. 2,4 illustrates the upward view of suction nozzle.Suction nozzle base plate 11 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, these openings can with surperficial substantially parallel direction to be cleaned on side direction suck.
A solid section 40 is finished triangle at the rear portion of suction nozzle, and this part has two positions 42 that are beneficial to the device that suction nozzle moves, and these devices can be the slide blocks of PTFE type, or wheel.
Suction nozzle has one in addition and extends to the thin slice 23 at edge 6 from the edge 5 of suction nozzle in the zone in 21, and 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 one and is provided with a known zone of pulling out wire fabric 24 own.
Can on an edge of passage 22, be provided with second and have a zone 28 of pulling out wire fabric, so as with zone 24 symmetries of pulling out line.
According to the present invention, each passage 19,20 have some in suction passage respectively from the edge 5 and the scraping blade 46 and 45 that extends to the direction at another edge of edge 6.According to the example that proposes, these scraping blades are fixed, and stretch out from the lower plate of suction nozzle, and to extend to the distance near passage one half width substantially parallel last with back 9.These scraping blades preferably lower plate unlike suction nozzle are outstanding or outstanding seldom.
Advantageously, the spacing between each scraping blade is not dark, and by a pedestal restriction that each scraping blade is formed, each pedestal extends to next scraping blade always.For example scraping blade 46 has a pedestal 47 that always extends to the scraping blade that is positioned at its front.As seeing among Fig. 4, the degree of depth of suction passage gradually changes along the side of suction nozzle, so the height difference of scraping blade pedestal.
The upper surface 66 of each pedestal can advantageously have an inclination towards suction passage, 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 along 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, or even 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 are along thin slice 23 processes of direction F from pulling out line.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.
Scraping blade 45,46 can act on the fiber on ground, the particularly ground of velvet carpet type effectively, and through out-of-date, scraping blade separates the fiber of velvet carpet at suction nozzle, so that realize sucking at fibrillar center.For example, suction nozzle is through out-of-date, owing to there are a plurality of parallel and continuous scraping blades, the fiber of velvet carpet by a scraping blade effect after, again by the scraping blade effect of back, described then fiber just can come back to its home position, and a longer effect and a suction degree of depth can be arranged on velvet carpet to be cleaned like this.
Hang over the kind of thread elements effect of pulling out by thin slice 23 of ground line and fiber, the advantage of thin slice is that its edge is two suction passages 18 and 22.No matter suction nozzle moves forward or backward, in both cases, in the motion of suction nozzle, pull out kind of thread elements to will and then once sucking after the effect on ground.
Embodiment shown in the invention is not restricted to.Can consider many modification.Can scraping blade be set along having the thin slice 23 of pulling out kind of thread elements, scraping blade extends on the whole length of passage, forms the space that bridge is the same on scraping blade, and air stream and rubbish, particularly maximum rubbish can freely be flowed on each scraping blade.Scraping the total length of sweeping will increase, and can improve suction efficiency like this.
In addition, scraping blade is preferably parallel with the back of suction nozzle, so that act on fiber by a scraping blade vertical with the suction nozzle moving direction.But, evidence, when there was certain gradient scraping blade and back, in the time of for example about 20 °, efficient slightly improved.A kind of explanation may be more complicated fibration mode, and is therefore more effective when scraping blade is not vertical with the moving direction of suction nozzle.
