Line 28 can be directly or indirectly connected to the host of rechargeable dust collector, receive electric power from main body of dust collector, and by suction airflow
It is transmitted to dust collector host.
The synthesis transmission ratio of second belt pulley of the sun gear and belt driving assembly of planetary gear set is 1:9.
Fig. 8 is the top view of floor brush of dust collector in the embodiments of the present invention；Fig. 9 is the B-B cross-sectional view of Fig. 8；Figure 10
It is the A-A cross-sectional view of Fig. 8, the axis of cutaway section process connection hard tube 26 is simultaneously vertical with the axis of round brush 14；And Figure 11 is
Partial enlarged view at the C of Figure 10
As shown in Fig. 9, Figure 10, Figure 11, upper cover 11 further includes between gas outlet 13 and round brush and being directed toward lower cover 12
Scraper plate 29, scraper plate 29 and upper cover 11 are integrally formed.Scraper plate 29 is along the axial length of round brush 14 not less than brush filament on 14 surface of round brush
The length of distribution.
Such as Figure 10, on the cutaway section of diagram, the vertical range of the lower edge and the inner surface of lower cover 12 of scraper plate 29 is
H1, the vertical range of the inner surface of the upper surface and lower cover 12 of gas outlet 13 are H2, H1 >=H2*2/3, preferably H1 >=H2, this
The reasons why sample designs is: the particulate dusts such as grain of rice are rolled up after gas outlet by round brush, or from two side of round brush to outlet
In mouth motion process, the grain of rice may hit the inner wall of round brush cavity, meet head on to hit with round brush again after being repelled, and the grain of rice is caused to fall into
Enter the brush filament depths on round brush, the bonding wire of scraper plate and round brush may be avoided, brush filament is followed to go to the front of scraper plate.H1 size
Amplification, that is, the contact point of scraper plate and round brush is raised, these can be given and rebounded into the grain of rice longer time in round brush, allowed
They can be from round brush depths to round brush apparent motion, to be intercepted by scraper plate, and then suction airflow is followed to flow by gas outlet 13
To dust collector host.Such as Figure 11, scraper plate lower edge 30 with round brush binding sites between 0 o'clock of round brush to 3 o'clock direction.Such as
On, by gas outlet axis and on the section vertical with round brush, scraper plate lower edge is H1 at a distance from 12 inner surface of lower cover,
The left and right sides of the cutaway section, scraper plate lower edge are preferably less than H1 at a distance from 12 inner surface of lower cover, so that from a round brush left side
The grain of rice that right two side impaction round brush chambers rebound again is easier to bump against the rear wall of scraper plate.
When round brush 14 rotates, at least partly the rotary motion trace at the tip of brush filament is contacted with the lower edge of scraper plate 29, so that
29 energy blocks dust of scraper plate, so dust will not cross scraper plate 29 and return to surface to be cleaned, but falls into air duct and is sucked away.Institute
There is the tip of brush filament to be preferably distributed in a cylindrical surface.
In the front of gas outlet 13, as H1 >=H2, the lower edge of scraper plate 29 is elevated, in order to ensure 29 lower edge of scraper plate
It is adjacent to the rotary motion trace of brush filament, the scraper plate 29 positioned at 13 front of gas outlet will be to front curve, as shown in figure 9, the middle part of scraper plate 29
Containing at least one section of curve, curve in the projection with horizontal plane direction is preferably circular arc.
The inside of the leading edge of upper cover 11 and the gap at brush filament tip are H3, medial surface and the brush filament point at the top of upper cover 11
The gap at end is H4, and the gap of 29 lower edge of scraper plate and brush filament tip rotary motion trace is H5.H3 and H5 is preferably zero, is also possible to
Negative, that is, 11 leading edge of upper cover inside and 29 lower edge of scraper plate can be with brush filament nib contacts, or even squeeze brush filament
Tip.H5 is preferably zero or negative, is the dust in order to stop round brush 14 to raise.H3 is preferably zero or negative, because of rolling
Brushing 14 high-speed rotations will drive the surface to be cleaned that air flows to 14 front of round brush above round brush 14, and dust is pushed away toward far from rolling
The direction of brush 14, has a negative impact to dust collection efficiency, is preferably zero or negative by H3, can effectively weaken this negative shadow
It rings.
The upper inside wall of upper cover 11 is greater than zero with the gap at brush filament tip, it is ensured that round brush 14 during rotation will not
By high resistance, therefore, gap H4 > H3.
In the present embodiment, motor speed 11000rpm, planetary gear set transmission ratio are 1:3, the diameter of the first belt pulley 22
It is 13.56, driving the diameter of second belt pulley 16 in 14 left side of round brush is 36.48, and the transmission ratio of belt is 1:3, planetary gear set
Synthesis transmission ratio with belt pulley is 1:9, so that driving revolving speed=10000/9=of second belt pulley 16 in 14 left side of round brush
1111rpm, the revolving speed of round brush 14 are also 1111rpm.In the present embodiment, the synthesis transmission ratio of transmission mechanism is 1:9, thus is rolled
14 available more large torques are brushed, and then the bigger resistance on surface to be cleaned can be overcome, it not only can be suitable on smooth earth
Smooth rotation, is also able to rotate freely on carpet.
The action and effect of embodiment
Floor brush of dust collector and dust catcher according to involved in the present embodiment, because floor brush of dust collector includes: main body；Rolling
Brush；And driving mechanism, wherein driving mechanism includes driving motor, for providing driving power；Planetary gear set, comprising according to
Sun gear, planetary gear and the gear ring of secondary engaged transmission, sun gear are socketed in the shaft of driving motor；And belt driving group
Part, including driven by planetary gear the first belt pulley, second belt pulley coaxial with round brush and connect the first belt pulley and
The belt of two belt pulleys, so, the floor brush of dust collector of the utility model passes through the planetary gear set and belt drive in driving mechanism
Dynamic component combines, and biggish transmission ratio is obtained, and then apply biggish torsion to round brush, so that round brush is also able to rotate on carpet
Freely, it and then improves cleaning efficiency and increases application scenarios.
In addition, in the present embodiment, because the scraper plate in front of gas outlet is relatively high, the lower edge of scraper plate reaches table in lower cover
The vertical range in face is H1, and the vertical range that lower interior surface is reached positioned at the upper surface of the gas outlet 3 at scraper plate rear is H2, H1
>=H2*2/3, preferably H1 >=H2, so, so that the front of gas outlet will not be blocked by scraper plate, dust is by scraper plate from round brush
After scraping off, it can more swimmingly enter gas outlet, it is easier to suction airflow be followed to be sucked away.
Above embodiment is the preferred case of the utility model, is not intended to limit the protection scope of the utility model.
