Abstract
The invention increases patting force of a rotary brush for improving dust suction performance by composing the brush in such a way that a rotation direction of a lower part of the brush is inverse to a flow direction of air inside a suction port body, sucked from a front part of the suction port body to flow out to the vacuum cleaner main body side. Because brush tip parts are not yet in contact with the floor surface at a position just before the nozzle body 5, the brush tip parts are kept radially stretched. Floor surface patting force by the brush tip parts can thus be set large.
Description
The present invention relates to the suction inlet body of dust catcher and have the dust catcher of this suction inlet body, particularly a kind of employing is the suction inlet body of the drive source dust catcher that can improve suction inlet body dust suction performance that makes the rotating brush rotation mode and the dust catcher with this suction inlet body with the air turbine.
The present invention also be particularly related to a kind of can when suction inlet body built on stilts, prevent noise and when the suction inlet body is moved forward and backward, can prevent change the suction inlet body produces the dust catcher that stings ear noise and dust catcher because of the rotating brush revolution with this suction inlet body.
Air turbine unit room and rotating brush chamber that the suction inlet body of dust catcher is provided with suction inlet body body housing and forms in this suction inlet body body housing.At the indoor rotating brush that can rotate freely that is equipped with of rotating brush.The mode that drives this rotating brush has motro drivien and air turbine drive-type.
With the rotating brush type of drive of motor as drive source, the weight of Yin Mada itself is big, so, cause the weight of suction inlet body of built-in this motor big.And, then do not have this shortcoming with the rotating brush type of drive of air turbine as drive source.So, adopt recently and extremely gaze at as the dust catcher suction inlet body of the rotating brush type of drive of drive source with air turbine.
In the past, employing is the dust catcher suction inlet body of the rotating brush type of drive of drive source with the air turbine, for example there is the Japanese patent gazette spy to open disclosed a kind of suction inlet body in flat 2-102626 number, in this suction inlet body body housing, separate and be provided with rotating brush chamber and air turbine unit room, on the partition wall of the suction inlet body body housing of separating this two Room, the nozzle body with nozzle is installed.
Jet-stream wind sprays to the lower side (ground side) of the indoor air turbine of air turbine from the nozzle of this nozzle body, that is, jet-stream wind is sprayed toward the oblique below of air turbine, makes the air turbine rotation.By synchronous belt the revolving force of this air turbine is passed to the indoor rotating brush of rotating brush.Make rotating brush bottom (ground side) with the suction inlet body of flowing through in the flow direction equidirectional of air on rotate, make rotating brush top (top surface side) with the suction inlet body of flowing through in the flow direction rightabout of air on rotate, carry out the cleaning work on ground.
The suction inlet body of this dust catcher in the past, when the state of built on stilts, to open with the by-passing valve of the pressure-sensitive wheel interlinked open-close that is installed in suction inlet body downside rear portion, the feasible flow velocity that sprays to the suction air of air turbine reduces, the revolution that suppresses air turbine, thus the noise that is taken place reduced.
Usually, people have such requirement to dust catcher suction inlet body: promptly, toward positive direction of advance when pushing away, the dust suction performance that sucks terrestrial dust will be higher than the dust suction performance when the suction inlet body retracted the underfooting to the operator the suction inlet body.In other words, that is, the operator is when the suction inlet body of positive direction of advance operation dust catcher, and the dust suction performance of suction terrestrial dust should be higher than the dust suction performance when operating on the rightabout of positive direction of advance.
The suction inlet body of above-mentioned this dust catcher in the past, because the direction of rotation of rotating brush is identical with air-flow direction in the suction inlet body in the bottom of rotating brush (ground side), so when the operator when positive direction of advance pushes away the suction inlet body, because the effect of the revolving force of rotating brush, the suction inlet body is pulled on positive direction of advance, and therefore having the suction inlet gymnastics makes light advantage.
But it is little that the suction inlet body of above-mentioned this dust catcher in the past, its rotating brush are kowtowed the strength of hitting ground, rotating brush a large amount of dust of can not kicking up are so the power that sweeps dust from ground is small and weak, thereby cause the dust suction amount of dust catcher few, can not increase substantially the dust suction performance of the suction inlet body of dust catcher.
Promptly, the suction inlet body of the dust catcher of rotating brush type of drive in the past, the bottom of its rotating brush (ground side) rotates on the direction identical with air-flow direction in the suction inlet body, so, the position that is provided with from nozzle, the brush nose part kowtow hit ground the position between the pivot and suction inlet of rotating brush, be not between the pivot of nozzle body and rotating brush.
Therefore, place, close nozzle body position at rotating brush, because the contact resistance of the carpet on ground or matting etc., the brush nose part just becomes the state with respect to the past rear bending of the direction of rotation of rotating brush, and the brush nose part of this bending just causes rotating brush that ground is not had the big power of hitting of kowtowing.Its result and since rotating brush to ground to kowtow the power of hitting little, no matter how it kowtows and hits ground a large amount of dust of can not kicking up.
Here, its rotating brush of suction inlet body and function of having a look above-mentioned dust catcher in the past sweeps the ability of terrestrial dust.If the rotary speed V of rotating brush
1' being about 5.0m/s, the operator operates the speed V of suction inlet body
2' be about 1.5m/s.
At this moment, because the direction of rotation of the bottom of ground rotating brush is opposite with the positive direction of advance that the operator promotes the suction inlet body, so the brush nose part is for the relative velocity V on ground
0' be rotating brush rotary speed V
1' make speed V with the suction inlet gymnastics
2' poor (V
0'=V
1'-V
2'), being about 3.5m/s, this value is smaller.So the power that sweeps dust at the indoor rotating brush of rotating brush from ground is very little.That is, the power that sweeps terrestrial dust owing to above-mentioned dust catcher suction inlet body in the past is very little, so the dust suction amount is few, the suction inlet body of this dust catcher does not have high dust suction performance.
As mentioned above, the rotating brush direction of rotation of this in the past dust catcher suction inlet body, the direction of rotation that is the bottom (ground side) of rotating brush be the positive direction of advance with the operator opposite (with the air-flow direction in the suction inlet body be identical, rotating brush to ground to kowtow the power of hitting little, the power that sweeps dust at the indoor rotating brush of rotating brush from ground is little, therefore, the dust amount of kicking up from ground is little, causes the dust suction quantity not sufficient of dust catcher.
Therefore, if the operator does not does not repeatedly come and go operation several times at ground same position place, inspiration dust fully just, this has just increased the weight of cleaning work person's burden.
Dust catcher suction inlet body in the past, in moving forward and backward the suction inlet body, backward during side shifting (drawing) suction inlet body, be used for bypass passageways is mentioned at suction inlet body rear slightly by the operator simultaneously, open with the pressure-sensitive wheel interlock that is installed in suction inlet body downside rear portion, have the problem that reduces dust collecting performance.
The suction inlet body forward during side shifting (pushing away), the direction of rotation of the bottom of rotating brush (ground side) and the moving direction of suction inlet body are rightabout, so revolution height of air turbine, when the suction inlet body backward during side shifting (drawing), the direction of rotation of the bottom of rotating brush and suction inlet body moving direction are same direction, so the revolution of air turbine is low.
Backward during side shifting (drawing), the user mentions slightly with handgrip suction inlet body rear the suction inlet body, and bypass passageways is with the pressure-sensitive wheel interlock that is installed in suction inlet body downside rear portion and open, and the revolution of air turbine reduces more.
Therefore, when the suction inlet body was moved forward and backward, air turbine changed greatly in the rotation number of fore-and-aft direction, and produces harsh noise.
In addition, the suction inlet body of dust catcher in the past, when the suction inlet body broke away from ground, the rotation of air turbine did not stop fully, so, can not prevent noise.
The objective of the invention is is being that drive source makes on the dust catcher suction inlet body basis of rotating brush rotation with the air turbine, a kind of suction inlet body of the dust catcher that can improve the dust suction performance is provided and has the dust catcher of this suction inlet body.The brush nose part of the rotating brush in the suction inlet body of the present invention is big with respect to the speed on ground, is kowtowed by the brush nose part of elongation in the front of nozzle body and hits ground, and the dust amount that makes ground kick up increases, thereby can improve the dust suction performance of dust catcher suction inlet body.
Specifically, the objective of the invention is is being that drive source makes on the dust catcher suction inlet body basis of rotating brush rotation with the air turbine, a kind of suction inlet body of the dust catcher that can improve the dust suction performance is provided and has the dust catcher of this suction inlet body.In the suction inlet body of the present invention, the brush nose part of its rotating brush is big with respect to the speed on ground, the brush nose part of rotating brush does not bend, kowtow by brush nose part elongation or that do not bend in the front of nozzle body and to hit ground, increase rotating brush kowtowing the power of hitting and sweeping the power of terrestrial dust to ground, the dust amount that makes ground kick up increases, thereby can improve the dust suction performance of the suction inlet body of dust catcher.
Other purpose of the present invention provides a kind of suction inlet body of dust catcher that can prevent and noise takes place and can prevent when moving forward and backward the suction inlet body to change dust catcher suction inlet body that produces the thorn ear noise and the dust catcher with this suction inlet body because of the air turbine revolution when built on stilts.
To achieve these goals, the suction inlet body of dust catcher of the present invention is provided with: suction inlet body body housing, be formed in the suction inlet body body housing and air turbine unit room with the rotatable air turbine of a plurality of blades is housed, in suction inlet body body and rotating brush chamber air turbine unit room configured in parallel and that the rotatable rotary brush is housed, be located between air turbine unit room and the rotating brush chamber and jet-stream wind makes the nozzle body of air turbine rotation, the rotation of air turbine passed to rotating brush and transmission driving mechanism that rotating brush is rotated; It is characterized in that the direction of rotation of the bottom of rotating brush is opposite with the flow direction of air in the suction inlet body that sucks and flow out to body of dust collector from suction inlet body front portion.
Among the present invention, above-mentioned suction air-flow is ejected into the air turbine top, and these two direction of rotation of the direction of rotation of the direction of rotation of the bottom of rotating brush and the bottom of air turbine are opposite with the flow inversion of air in the suction inlet body that sucks and flow out to body of dust collector from suction inlet body front portion.
The nozzle center line of above-mentioned nozzle body tilts with respect to horizontal line, and square neck is oblique obliquely by the nozzle body of air turbine one side, tilts towards oblique below by the nozzle body of rotating brush one side.
The nozzle fixing body that nozzle body nozzle is installed is configured in the suction inlet body body housing obliquely, the top of this nozzle fixing body is near rotating brush one side, the bottom of this nozzle fixing body is installed in the suction inlet body body housing with this state near air turbine one side.
The extended line and the air turbine blade periphery tangent line of the nozzle upper opening portion inner face of above-mentioned nozzle body are unanimous on the whole, and the wall that leans on rotating brush one side of nozzle fixing body and the center line position of intersecting point of nozzle body nozzle are positioned at the horizontal below of passing the air turbine pivot.
In addition, the invention still further relates to the dust catcher that above-mentioned structure suction inlet body is installed.
In the present invention, so-called ground is meant swept surface, for example is carpet, matting, floor etc.
In the present invention, the brush nose part of so-called rotating brush when constituting rotating brush with brush, is meant the fore-end of brush, when constituting the brush of rotating brush with scraping blade, is meant the fore-end of scraping blade.
Characteristics of the present invention are, when (pushing away) moved in the past the place ahead of the suction inlet body of dust catcher, suck air and be directed to the air turbine top that drives rotating brush, the direction of rotation of the bottom of rotating brush with from the suction inlet body anterior suck and the suction inlet body of flowing through in air-flow direction opposite, when the suction inlet body leaves cleaning face, open with the by-passing valve of the wheel interlock that is located at suction inlet body bottom, thereby prevent to rotate the noise that produces because of the high speed of air turbine.
Promptly, feature of the present invention is, the air stream of nozzle ejection is directed to the top of air turbine, the direction of rotation of the bottom of rotating brush with from the suction inlet body anterior suck and the suction inlet body of flowing through in air-flow direction opposite, at the indoor by-passing valve that is provided with of air turbine with switching function.
Feature of the present invention also is, when suction inlet body built on stilts, utilizes and be located at the arrestment mechanism of the wheel interlock of suction inlet body bottom, and the transmission driving mechanism that links rotating brush and air turbine is invested resistance, stops the rotation of air turbine.
According to above-mentioned structure of the present invention, the jet-stream wind that comes from nozzle body nozzle is ejected on the top blade of air turbine, make the direction of rotation of bottom (ground side) of air turbine and rotating brush with opposite from the anterior flow direction of air in the suction inlet body that sucks and flow out to body of dust collector of suction inlet body, that is to say that to promote the positive direction of advance of suction inlet body consistent with the operator, so the brush nose part of rotating brush is kowtowed the position of hitting ground can be in the front of ejectisome.
Simultaneously, front at ejectisome, because the brush nose part of rotating brush is not in contact with the ground, so can not become bending state, the brush nose part is radial extended configuration, therefore, the brush nose part of rotating brush to ground to kowtow the power of hitting big, the dust amount of being kicked up from ground by the kowtowing the power of hitting of rotating brush is comparable to be increased approximately 35% in the past, can improve the dust suction performance of the suction inlet body of dust catcher significantly.
Here, the rotating brush of having a look dust catcher suction inlet body of the present invention sweeps the power of terrestrial dust.If the rotary speed V of rotating brush
1Be about 5.0m/s, the speed that the operator operates the suction inlet body on the ground is about 1.5m/s, and this two speed is identical with the speed of dust catcher suction inlet body in the past.But, since by the direction of rotation of the bottom of the rotating brush of ground side with from the anterior suction of suction inlet body and to flow out to the flow direction of air in the suction inlet body of body of dust collector opposite, and it is identical with the direction of operating (operator pushes away the suction inlet body toward the front) of suction inlet body, so rotating brush is for the relative velocity V on ground
0Be two speed (the rotary speed V of rotating brush
1Service speed V with the suction inlet body
2) sum (V
0=V
1+ V
2), be about 6.5m/s.
Like this, the rotating brush among the present invention is for the relative velocity V on ground
0(about 6.5m/s) is about in the past rotating brush for the relative velocity V on ground
02 times of ' (about 3.5m/s) increase much so rotating brush sweeps the power of terrestrial dust, can increase substantially the dust suction performance of suction inlet body.
As mentioned above, among the present invention because rotating brush increases the power of kowtowing the power of hitting and sweeping terrestrial dust on ground, so that the dust amount of kicking up in ground increases considerably, the dust suction performance of suction inlet body also increases substantially.Like this, the operator just there is no need to repeat several times back and forth operation suction inlet body at ground same position place, can alleviate operator's burden greatly.
Above-mentioned suction inlet body of the present invention is to adopt air turbine to drive the mode of rotating brush, does not have motor, can alleviate the suction inlet body weight.So,, also can keep the operability of dust catcher suction inlet body well even make the direction of rotation of bottom of rotating brush with opposite from the anterior flow direction of air in the suction inlet body that sucks and flow out to body of dust collector of suction inlet body.
The center line of the nozzle of nozzle body tilts with respect to horizontal line, and air turbine is at the oblique upper of nozzle.Therefore, the jet air-flow that the comes from nozzle body nozzle blade of impinging air turbine effectively.
In addition, the nozzle fixing body of nozzle body with respect to the ground vertical line forward square neck tiltedly be installed in the suction inlet body body housing, so, can increase near the suction inlet body space volume the ground in front of the nozzle body.Like this, suck air-flow and just in front of the nozzle body, drop near the ground, can be so that enter the nozzle of nozzle body quickly at the indoor dust of kicking up of rotating brush by rotating brush.
Because the extended line of the nozzle upper opening portion inner face of nozzle body roughly becomes consistent with the tangent line of air turbine blade periphery, and be installed with nozzle the nozzle body by the position of intersecting point of rotating brush side wall surface and nozzle body nozzle center line below the horizontal line that passes the air turbine pivot, so, come from the blade of most of jet-stream wind percussion air turbine of nozzle body nozzle, can increase the revolving force of air turbine.
According to the present invention, because the direction of rotation of the bottom (ground side) of the rotating brush of suction inlet body is opposite with the flow direction of air in the anterior suction of suction inlet body and the suction inlet body of flowing through, so, increase the kowtow dust amount that hit effect and kick up swept surface of rotating brush to swept surface (ground), can increase substantially the dust suction performance of suction inlet body.
Therefore, when cleaning ground, can finish cleaning work convenient and time-savingly, alleviate operator's labour significantly with dust catcher with this high dust suction performance suction inlet body.
According to the present invention, because the direction of rotation of the bottom of the direction of rotation of the bottom of rotating brush and air turbine is opposite with the flow direction that sucks air-flow, so can improve dust collecting performance.Simultaneously, when moving forward and backward the suction inlet body, can also prevent to change the thorn ear noise that produces because of the air turbine revolution.In addition, because the rotation of air turbine is stopped fully, so can prevent the generation of noise.

Below, with reference to an embodiment of description of drawings dust catcher suction inlet of the present invention body.
Fig. 1 is the overall perspective view of dust catcher suction inlet body, and Fig. 2 is the skiagraph of suction inlet body.Among Fig. 1 and Fig. 2, rotating brush chamber 3 and air turbine unit room 4 that suction inlet body 1 is formed in the suction inlet body body housing 2 substantially by suction inlet body body housing 2, separatedly constitute.
Suction inlet body body housing 2 is divided into two parts up and down, is made of suction inlet body body upper case 2a, mask for inhalation 2b and suction inlet body lower body shell 2c.On suction inlet body body 2, be formed with rib 2d, between rib 2d, disposing nozzle body 5.In rotating brush chamber 3, dispose rotation rotating brush 6 freely, in air turbine unit room 4, disposing the rotatable air turbine 7 that has some blades.
In the present embodiment, be configured in the rotating brush 6 in the rotating brush chamber 3, be respectively one sweep dust effective, have flexual scraping blade 6a and good brush 6b of wiping effect to be rolled into helical form to install and constitute.The air turbine 7 that is configured in the air turbine unit room 4 is cut apart the impeller 7a and the impeller 7b that form and is constituted by having some blades and being symmetric figure.
In addition, this rotating brush also can only be rolled into two brushes helical form and install and form, and also two scraping blades and two brushes can be amounted to four and be rolled into helical form respectively and install and form.
In air turbine unit room 4, above air turbine 7, form the space, form air flow air stream 8.At the downstream side of this air flow circuit 8, be provided with air-flow gathered import body of dust collector 20(and see Fig. 7) receiving port 9.Air turbine 7 is installed on the air turbine rotating shaft 10.Between the rotating brush rotating shaft of this air turbine rotating shaft 10 and rotating brush 6, be provided with as the synchronous belt 11 that transmits driving mechanism.
In the rearward end of suction inlet body 1, be provided with the box body 21 that can rotate up and down, rotating suction inlet joint 22 is connected the front end of this box body 21.Suction inlet body 1 is installed to (see figure 7) on the body of dust collector 20 by suction inlet joint 22.
The structure of nozzle body 5 is described with Fig. 4, Fig. 5 and Fig. 6 now.Nozzle body 5 chews 5b by nozzle installing plate 5a, main jet and secondary nozzle 5c constitutes.As mentioned above, this nozzle body 5 is installed on the rib 2d, and this rib 2d is formed between rotating brush chamber 3 and the air turbine unit room 4.
The main jet of nozzle body 5 is chewed the opening that 5b has circular cross section, is disposing highlightedly obliquely upward towards air turbine 7.This main jet is chewed 5b and spray the air stream that makes air turbine 7 rotations in air turbine unit room 4.Secondary nozzle 5c and main jet are chewed 5b and are being provided with side by side, to the indoor jet airstream of air turbine.The opening-closing plate that the secondary nozzle 5c of this ejectisome 5 is moved by horizontal direction opens and closes the opening of secondary nozzle 5c.
When ground is under the situation of carpet, closes the opening of secondary nozzle 5c, only chews opening jet airstream in air turbine unit room 4 of 5b from main jet, can obtain strong revolving force from air turbine 7.When ground is under the situation on matting or floor, the opening of open secondary nozzle 5c, with the opening of chewing 5b from main jet similarly to air turbine unit room 4 jet airstreams, can obtain weak revolving force from air turbine 7.
Behind the starting dust catcher power supply, suck air from the suction inlet of suction inlet body 1 front portion, this suction air (suction air-flow) 14 is flowed through in the suction inlet body, flows out to body of dust collector 20 from receiving port 9.That is, suck air (suction air-flow) 14 according to: the order that the main jet of ground → rotating brush chamber 3 → nozzle body 5 of suction inlet body body lower case 2c is chewed the air flow circuit 8 → receiving port 9 of 5b → air turbine 7 → air turbine 7 tops flows.
In the present embodiment, because it is just outstanding obliquely that the main jet of nozzle body 5 is chewed the opening of 5b, so, can strengthen the spatial volume of rotating brush one side of nozzle body 5, just strengthen near the spatial volume (spaces between rotating brush 6 rear lower portion and the nozzle body 5 forward lower part sides) in nozzle body 5 openings inlet ground, bottom.
Like this, the suction air-flow 14a of rotating brush 6 tops becomes suction air-flow 14b near the front of nozzle body 5 runs down into ground.This suction air-flow 14b is entangled in the dust of kicking up in rotating brush chamber 3, and the main jet that flows into nozzle body 5 is chewed the opening of 5b, becomes jet-stream wind 14c and flows into the air turbine unit room.
Jet-stream wind 14c flows into air turbine 7 inside, bump against with the blade of air turbine 7 tops of air turbine unit room 4, the kinetic energy of jet-stream wind 14c invests air turbine 7 revolving forces (torque), the revolving force that this air turbine 7 obtains passes to rotating brush 6 by synchronous belt 11, and rotating brush 6 and air turbine 7 are rotated on same direction.
As shown in Figure 2, in the above embodiment of the present invention, the main jet that comes from ejectisome 5 is chewed the jet-stream wind 14c of 5b with respect to the past oblique upper ejection in ground, is injected on top (top surface side of the air turbine unit room 4) blade of air turbine 7.Its result, the direction of rotation a of the bottom of air turbine 7 (ground side of air turbine unit room 4) is opposite with the flow direction that sucks air-flow 14.
The revolving force of air turbine 7 passes to rotating brush 6 by synchronous belt 11, and the direction of rotation C of these rotating brush 6 bottoms (ground side of rotating brush chamber 3) is identical with the direction of rotation of air turbine 7, and is opposite with the flow direction that sucks air-flow 14.
That is, when suction inlet body 1 is moved toward the direction that pushes away when mobile (make suction inlet body 1 advance toward the place ahead), the direction of rotation C of rotating brush 6 bottoms is opposite with the flow direction of suction air-flow 14.(the suction inlet body is retired when moving) toward the body front and back when suction inlet body 1 is moved toward the direction of drawing, the direction of rotation C of rotating brush 6 bottoms is also opposite with the flow direction that sucks air-flow 14.
In other words, when suction inlet body 1 is moved toward the direction that pushes away when mobile (make suction inlet body 1 advance toward the place ahead), the direction of rotation C of rotating brush 6 bottoms is identical with the forward operation direction; (suction inlet body 1 is retired when moving) toward the body front and back when suction inlet body 1 is moved toward the direction of drawing, the direction of rotation C of rotating brush 6 bottoms is opposite with the back operation direction.
For top blade with jet-stream wind 14c guiding air turbine 7, in the present embodiment, stipulated that the main jet of the installation site of nozzle installing plate 5a of nozzle body 5 and nozzle body 5 chews the opening direction of 5b, be described with Fig. 3.
As shown in Figure 3, the nozzle installing plate 5a of nozzle body 5 is installed with obliquely with respect to ground perpendicular C, like this, see that the position A of upper side (top surface side) is just at the upstream side (operator's front side) of the position B of lower side (ground side) along the flow direction of air.In addition, the main jet of nozzle body 5 is chewed 5b and is installed in this wise on the nozzle installing plate 5a,, chews the opening downstream side (main jet is chewed the opening inlet of 5b) of 5b at the main jet of air stream that is, and center line D stretches out with respect to the past oblique upper of horizontal line E.
Test according to present inventor etc. learns, when the nozzle installing plate 5a of nozzle body 5 tilt angle theta with respect to vertical line C
1For in about 15-45 degree scope the time, can make the operating efficiency of air turbine 7 higher, in the present embodiment, tilt angle theta
1Be set at 30 degree.
According to present embodiment, because the direction of rotation of the bottom of rotating brush 6 is a C direction shown in Figure 2, so rotating brush C kowtows the position of hitting ground can be between the pivot and nozzle body 5 of rotating brush 6.Like this, just can kowtow the set positions of hitting ground front to rotating brush 6, that is, can be set in front of the opening inlet of nozzle body 5 at the nozzle body 5 on rotation side.Position in nozzle body 5 fronts, the brush nose part of rotating brush 6 does not also have kiss the earth, do not bend so brush nose part, and radial extended configuration.
Therefore, it is big that the brush nose part of rotating brush 6 is kowtowed the power of hitting ground, no matter the operator is at positive direction of advance b or at rightabout (direction of retreat) the operation suction inlet body 1 of this front direction of advance b, near ground dust rotating brush 6 fronts of kicking up.Especially as operator during at positive direction of advance b operation suction inlet body 1, in front of rotating brush 6 sweeps near the power of terrestrial dust big, so the nozzle body 5 side terrestrial dusts of rotating brush 6 fronts of kicking up in large quantities.
