The specific embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of dust catcher specific embodiment with scrubbing brush, it comprise above scrubbing brush loam cake 10, below scrubbing brush pedestal 12, be arranged on integral rolling brush 20 between scrubbing brush loam cake 10 and the scrubbing brush pedestal 12, be arranged on the rear wireway 30, be arranged on a pair of rear roller 40 below the wireway 30 and a pair of front wheel 42 that is located at the place ahead, scrubbing brush pedestal 12 bottom.Wherein integral rolling brush 20 comprises blade disposed thereon 22.
Again in conjunction with shown in Fig. 3-4; scrubbing brush pedestal 12 comprises the scrubbing brush sidewall 14 that is formed at both sides; be positioned at the place ahead and the ceiling 16 on the scrubbing brush sidewall 14; be positioned at the round brush chamber 120 of two scrubbing brush sidewalls, 14 centres; be positioned at 120 the place aheads, round brush chamber and be communicated with and be positioned at two inlet channels 122 of scrubbing brush pedestal 12 bottom surfaces with round brush chamber 120; be positioned at 120 both sides, round brush chamber and be communicated with and be positioned at an offside inlet channel 124 of scrubbing brush pedestal 12 bottom surfaces with round brush chamber 120; and be connected with corresponding side inlet channel 124 and be positioned at a pair of recess 126 of scrubbing brush pedestal 12 bottom surfaces; wherein integral rolling brush 20 is installed in the round brush chamber 12; wireway 30 is positioned at 120 rears, round brush chamber and is connected with round brush chamber 120; the distance from bottom ground level h of scrubbing brush sidewall 14 is preferably less than 1mm, more preferably smaller or equal to 0.5mm.Side inlet channel 124 is outer narrow inner width, it comprises the side-inlet 1240 that is positioned on the scrubbing brush sidewall 14 and is positioned at side gas outlet 1242 on 120 lateral edges of round brush chamber, wherein the sectional area of side-inlet 1240 is less than the sectional area of side gas outlet 1242, and the sectional area of side-inlet 1240 is less than 8mm
2, the sectional area of side gas outlet 1242 is greater than 8mm
2And less than 18mm
2Be provided with thus and can guarantee to form between side-inlet 1240 and the side gas outlet 1242 a middle negative pressure region, be connected to the round brush chamber 120 of negative pressure maximum with transition, be arranged near side-inlet 1240 dusts thus and be easy to enter into side inlet channel 124, and and then enter in the round brush chamber 120, then to cause the dust of side to be not easy to be drawn into round brush indoor because of not having middle negative pressure region for the side inlet channel of existing floor brush of dust collector, causes dust removal ability poor excessively.The opening of recess 126 is towards side inlet channel 124, and extend to form recess 126 to the bottom by both sides of the edge, these both sides of the edge comprise the outer ledge 1260 near scrubbing brush sidewall 14, inside edge 1262 near round brush chamber 120, wherein the length of inside edge 1262 extension downwards is less than outer ledge 1260 downward length of extending, be outer ledge 1260 than inside edge 1262 face closer, wherein overhead highly preferably less than 1mm, more preferably smaller or equal to 0.5mm, realize better sealing by outer ledge 1260 like this, and owing to recess 126 is connected with side inlet channel 124, the part dust can enter into recess 126, and can enter in the round brush chamber 120 by inside edge 1262, help the dust cleaning.Simultaneously there are difference in height in the end face of recess 126 and the end face of side inlet channel 124, and the end face of recess 126 is than the end face of side inlet channel 124 face closer.Inlet channel 122 comprises the air inlet 1220 that is positioned on the ceiling 16 and is positioned at gas outlet 1222 on 120 leading edges of round brush chamber, and wherein the sectional area of gas outlet 1222 is less than the sectional area of air inlet 1220, and the sectional area of air inlet 1220 is preferably less than 150mm
2, the height H of air inlet 1220 is preferably less than 5mm, and the sectional area of gas outlet 1222 is preferably smaller or equal to 75mm
2, the height H of gas outlet 1222 is preferably smaller or equal to 2mm, and the accumulative total sectional area of two air inlets 1220 will guarantee less than 300mm simultaneously
2, guarantee that thus the air inlet wind speed is higher, and then easier absorption is positioned at the dust in the place ahead.
During work, the vacuum motor of dust catcher (not shown) rotates and the generation vacuum at a high speed, dust-contained airflow enters from the inlet channel 122 in the place ahead, because inlet channel 122 sectional areas are along with the air intake direction diminishes gradually, wind speed promotes gradually, and enter in the scrubbing brush chamber 120, accelerate the high speed rotation of blade 22 then, thereby drive the rotation of integral rolling brush 20, and since the distance from bottom ground level h of scrubbing brush sidewall 14 less than 1mm, realize scrubbing brush sidewall 14 and the better sealing in ground, and the sectional area by side-inlet 1240 is less than 8mm
2, easier absorption is positioned at the dust of scrubbing brush sidewall 14, enter into then in the round brush chamber 120, and the place ahead and side air-flow enters into wireway 30 again through after the integral rolling brush 20, enter in the vacuum motor thus.
The utility model is under the condition that reduces as far as possible the influence of round brush rotating speed, improved the ability of scrubbing brush the place ahead and side cleaning, improved the efficient of scrubbing brush, the pick-up performance to the turning of working environment and dead angle is good especially, and has reduced the loss that round brush is driven wind-force.Improved the round brush driving force simultaneously, the negative pressure of round brush chamber also obviously improves, and cleaning capacity improves, and structure realizes simple and reliable.
Certainly the foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
