May there be a lot of embodiment in dust catcher brush group according to the present invention, will explain most preferred embodiment below.
Fig. 2 is the front view of robot cleaner according to an embodiment of the invention, and Fig. 3 is the upward view of robot cleaner according to an embodiment of the invention, and Fig. 4 is the cutaway view of robot cleaner according to an embodiment of the invention.
Robot cleaner according to the present invention comprises: main body of dust collector 10; Be installed in the suction fan 12 in the main body of dust collector 10, be used for producing the inhalation power of dust catcher; Filter container 16, it is installed in suction fan 12 fronts and is provided with filter 14 within it, is used for collecting dust or the dirt that is sucked by suction fan 12; Suction inlet 20, it is connected to filter container 16 by suction line 18, and the bottom that is formed at main body 10 is to suck dust or the dirt on the floor 30; And the brush group 22 that is rotatably installed in suction inlet 20 1 sides, it is used for clearing away dust and dirt on the floor 30.
In the back of main body of dust collector 10 charging end 28 is installed, when charging end 28 is connected to the link 42 that is installed on the room wall 40, battery 32 is charged.In addition, light-emitting component 34 is installed, is used for charging end 28 is guided to link 42 in the back of main body of dust collector 10, and, on the room wall 40 that link 42 is installed, light receiving element 44 also is installed, be used to receive optical signalling from light-emitting component 34 emissions.
The a pair of driving wheel 38 that drives by motor 36 and supporting main body of dust collector 10 and keeping the auxiliary wheel 48 of level to be installed in the bottom of main body of dust collector 10.
Fig. 5 is a stereogram of brushing group according to an embodiment of the invention, and Fig. 6 is a side view of brushing group according to an embodiment of the invention.
Here, first magnet 60 and second magnet 62 are all made disc, and the attraction force acts between first magnet 60 and second magnet 62 is provided with less than the revolving force of drive motors 50.
And first magnet 60 that faces with each other and the surface of second magnet 62 have opposite polarity, thereby can produce attraction force acts between first magnet 60 and second magnet 62.That is to say that as an embodiment, if the opposed face of first magnet 60 is north (N) utmost point, then the opposed face of second magnet 62 is south (S) utmost point.
In another embodiment, the driving force conveyer comprises: be installed in the magnet (not shown) in the rotating shaft 54 of drive motors 50; And be installed in the rotating shaft 56 of brush 52 and arrange facing to the magnet (not shown) of this magnet.Therefore, utilize the attraction force acts between magnet (magnetic body) and the magnet (magnet), the revolving force of drive motors 50 is sent to brush 52.If for example produced load owing to brush 52 is blocked by foreign material, then the magnetic force of magnet is overcome, and has only magnet to be rotated, thereby the load transfer that has prevented to produce at the brush place is to drive motors 50.
In another embodiment of driving force conveyer, the magnet (not shown) is installed in the rotating shaft 54 of drive motors 50, and the magnet (not shown) is installed in the rotating shaft 56 of brush 52, wherein, magnet and magnet arrangement get mutually facing to.
To explain operation below according to dust catcher of the present invention.
Shown in Fig. 7 and 8 is the diagrammatic sketch of operating according to dust catcher brush group of the present invention.
When user's push button, the electric weight of battery 32 is transferred to suction fan 12, and drive this suction fan 12.Then, the driving by suction fan 12 produces inhalation power, is collected in the filter 14 by suction line 18 then so that the dust on the floor 30 or dirt are drawn to suction inlet 20.
At this moment, rotary brush 52 is to sweep dust on the floor and dirt in the suction inlet 20.That is to say, the revolving force of drive motors 50 is sent to brush 52 by driving force conveyer 58, thus rotary brush 52.
To explain the operation of driving force conveyer 58 below.At first, as shown in Figure 7, when drive motors 50 is driven, first magnet 60 that is installed in the rotating shaft 54 of drive motors 50 is rotated, then, arrange facing to second magnet 62 of first magnet 60 owing to the attraction force acts between himself and first magnet 60 is rotated, thereby allow brush 52 rotations that are connected to second magnet 62.
As shown in Figure 8, in cleaning, even owing to foreign material 70 grades unexpectedly enter when between brush 52 and the suction inlet 20 brush 52 can not be rotated, because the revolving force of drive motors 50 is greater than the attraction force acts between first magnet 60 and second magnet 62, drive motors 50 continues and rotation normally.Therefore, can prevent that the drive motors that causes owing to overload from damaging.
In the dust catcher brush group of constructing and operating according to this mode, first magnet and second magnet are arranged between drive motors and the brush in opposed facing mode, utilize the attraction force acts between first magnet and second magnet, send the revolving force of drive motors to brush, like this, even brush is owing to being blocked by foreign material etc. when stopping the rotation, drive motors also can normally rotate.Therefore, can prevent that drive motors is damaged because of overload.
In addition, because brush is only driven by the power corresponding to the attraction force acts between first magnet and second magnet, if serious friction has taken place between brush and the floor, thereby then brush can stop the rotation and prevents the floor damage.
Should be appreciated that, under the prerequisite that does not deviate from essence of the present invention or substantive characteristics, the present invention can implement in many ways, so unless otherwise indicated, embodiment described above is not limited by any details of above stated specification, on the contrary, should do the understanding of broad sense in the spirit and scope that claims limited, therefore, those fall into institute in the claim scope and change or revise or equivalent that this scope is interior is all contained by claims.
