Holding force.
As shown in fig. 4-5, in some embodiments of the utility model, the free end of the second extension 412 can be set
There is idler wheel 500.When dust catcher 1 moves, the rotation of idler wheel 500 instead of the free end of the second extension 412 translational motion, from
And can reduce the frictional force between the free end and ground of the second extension 412, the loss of dust catcher 1 is reduced, so as to mention
The comprehensive performance of high dust catcher 1.Moreover, in base lid 200 relative in 100 rotation process of scrubbing brush, due to the round slip surface of idler wheel 500
Effect, so that rotation is easier to realize.
As shown in figure 5, the second extension 412 may include first segment 414 and in some examples of the utility model
Two section 415, first segment 414 can extend along the radial direction of pivotal axis 400, and first segment 414 can be connect with pivotal axis 400.
Second segment 415 is vertical with first segment 414, and one end of second segment 415 is connect with first segment 414, and the other end of second segment 415 is suitable for
It offsets with ground.It is understood that the second extension 412 has 90 degree of turnings 413, the second extension 412 is divided at turning 413
For first segment 414 and second segment 415, first segment 414 can extend along the extending direction of the first extension 411, and first segment 414 can
To extend along ground, first segment 414 can be connect with pivotal axis 400, and second segment 415 can offset with ground.Thus, it is possible to logical
Cross face base lid 200 and the second round brush 300 supporting role with being vertically arranged realization of first segment 414 and second segment 415, and branch
It is preferable to support effect.
Some embodiments according to the present utility model, ground brush assemblies 10 can also include return unit 600, return unit 600 with
Base lid 200 and the connection of scrubbing brush 100 are often to drive base lid 200 towards ground rotation.It is understood that one end of return unit 600
It is connect with base lid 200, the other end of return unit 600 is connect with scrubbing brush 100, and without external forces, return unit 600 drives
Base lid 200 rotates, and rotation direction is the direction from the top on ground to ground.Return unit 600 can have base lid 200 as a result,
There is the component towards ground, so that the second round brush 300 and normal ground face contact, cleanly in order to the second round brush 300
Face.
Further, return unit 600 can be torsional spring 610.One end of torsional spring 610 can be connect with base lid 200, torsional spring
610 other end can be connect with scrubbing brush 100.The other end of one end of torsional spring 610 and torsional spring 610 at an angle, works as external force
One end of torsional spring 610 is acted on, when so that the angle between one end of torsional spring 610 and the other end of torsional spring 610 expanding, torsional spring
610 can often push one end of torsional spring 610 close to the other end of torsional spring 610, so that base lid 200 is to close to scrubbing brush 100
Direction rotation, and then can make the second round brush 300 to close to ground direction rotate.For example, as shown in Fig. 2-Fig. 3, it is multiple
Position part 600 can be set on pivotal axis 400, and one end of torsional spring 610 can be connect with base lid 200, and the other end of torsional spring 610 can
To be connect with scrubbing brush 100.
Some embodiments according to the present utility model, base lid 200 have accommodating chamber, and the side towards ground of accommodating chamber is spacious
It opens, the second round brush 300 can be located in accommodating chamber.It is understood that base lid 200 can be in half-surrounded, base lid 200 has
Accommodating chamber, the second round brush of part 300 are located in accommodating chamber, and the second round brush of part 300 is located at outside accommodating chamber, and exposed in accommodating chamber
Outer the second round brush of part 300 can be with ground face contact to carry out fugitive dust, cleaning to ground.Thus, it is possible to by the second round brush 300
The non-appearance face of dust catcher 1 is set, so as to improve the overall aesthetics of dust catcher 1.
Other embodiment according to the present utility model, the both ends on the axis direction of the second round brush 300 can have side
Side hair 310.For example, as shown in Figure 1, the second round brush 300 is cylindrical, on a left and right (left side as shown in Figure 1 for the second round brush 300
It is right) side hair 310 can be equipped on two end faces.Side hair 310 can protrude into corner, furniture corner or other second round brush
300 can not clean narrow zone, utilize the rotation of the second round brush 300 that side hair 310 is driven to rotate, the side of rolling hair 310
The dust in corner can be not only swept, but also the air on periphery can be driven to form air-flow, and then drive dust to raise, and lead to
It crosses dust and gas import 110 and dust is sucked into dust catcher 1, dust raises up, and effect is good, cleaning capacity is good.
Some examples according to the present utility model, dust and gas import 110 can be one and dust and gas import 110 is elongated,
Dust and gas import 110 extends along the length direction of the first round brush.For example, be as shown in Figure 1 the bottom view of dust catcher 1, the ground in figure
Brush 100 is rectangle, scrubbing brush 100 has a dust and gas import 110 of strip, the length direction of scrubbing brush 100, dust and gas import 110
The axis direction of strip extending direction and the second round brush 300 is unified, is left and right directions shown in FIG. 1.Thus, it is possible to improve
The mating reaction of first round brush, the second round brush 300 and dust and gas import 110, by the first round brush, the second round brush 300 or side hair
310 dusts raised can suck dust catcher 1 by dust and gas import 110 as much as possible, so as to improve the cleaning of dust catcher 1
Effect.
