In concrete meaning.
Referring to Fig. 1-Fig. 2, the embodiment provides a kind of sweeping robots comprising electric machine assembly 2 and scrubbing brush
Component 1, ground brush assemblies 1 include scrubbing brush inner cavity 11, round brush 12 and scraping article 13, and round brush 12 is placed in scrubbing brush inner cavity 11, in scrubbing brush
Suction inlet is set on the inner wall of chamber, when working with sweeping robot for direction of advance F, after scraping article 13 is set to scrubbing brush inner cavity 11
Side is provided with platform 14, air outlet is arranged on platform 14 in order to facilitate the installation of scraping article 13 between scraping article 13 and scrubbing brush inner cavity 11
15.In dust removal process, air outlet 15 sprays gas, and tiny dust can be prevented to be adhered on the platform 14.It needs to illustrate
, bonding can be used in the connection type of scraping article, card slot connects etc., referring to Fig. 3-embodiment shown in Fig. 4, card slot is used to connect
The mode connect.It should be noted that sweeping robot is in use, tiny dust is easily adhered on the platform, is rolled simultaneously
When brush rotation, the dust being thrown out of is adhered on the side wall of scraping article, once for a long time, it is difficult to it removes, for above technical problem,
Be inventor finds by long-term careful observation, user can ground brush assemblies and sweeping robot after a period of use,
It just will recognize that cleaning bottom surface, without the reason for going the positions such as analysis platform and scraping article side wall dust stratification serious, and go to hinder in advance
The only dust stratification at these positions.
In certain embodiments, air outlet 15 is arranged towards ground, and such setting form is relatively simple, easy to accomplish.?
Air outlet 15 is arranged towards round brush 12 in some embodiments.When being rotated due to round brush 12, it can take up dust, and rearward throw away,
By such setting, so that the air-flow that air outlet 15 sprays generates a resistance to the dust thrown away, can prevent to be thrown out of
Dust is adhered on the side wall of scraping article 13 and on platform 14.Setting to achieve the above object, those skilled in the art can adopt
Different technologies means are taken to realize.In certain embodiments, in order to reach more preferably technical effect, the inclination angle of air outlet 15 is adjusted
Degree, so that air outlet 15 is obliquely installed simultaneously towards ground and round brush 12, even if the air-flow a part obtained at air outlet 15 blows to
Round brush 12, a part blows to ground.Preferably, in some embodiments, referring specifically to Fig. 4, air outlet 15 is connected with air-out passage
16, being arranged to for air-out passage 16 is upper and lower towards the inclination of scrubbing brush direction.Further, it is also possible to pass through the knot for being directly changed air outlet 15
Configuration formula, in some embodiments, the air-flow that passes through the structure type for changing 15 side edge of air outlet, and air outlet 15 is sprayed
Direction is changed；Air outlet can also be set to a kind of structure type for setting up nozzle, so that nozzle can be to round brush side
To outlet air.It is worth illustrating to be, using this structure type for setting up nozzle, can solve to existing some scrubbing brush groups
Part or sweeping robot carry out simple reformation, i.e., nozzle are installed on the platform directly between scraping article and scrubbing brush inner cavity, to solve
Certainly one of multiple technical problems that the application proposes.Certainly the mode installed, those skilled in the art can choose bonding, screw thread
The multiple technologies means such as connection, welding, clamping.Specific tilt angle those skilled in the art are according to actual selection, it is therefore an objective to be
, allow air-flow that the dust thrown away is effectively prevented to adhere on 13 side wall of scraping article and/or platform 14, this will not be detailed here.
In certain embodiments, referring to fig. 2, it in order to cover entire platform 14 as far as possible, and takes into account and increases 15 wind of air outlet
Pressure, air outlet 15 is set as slim-lined construction, including rectangle, arc, waveform etc., the rectangle preferably readily processed.It needs
Illustrate, in order to reach better effect, in some embodiments ,-Fig. 3, is provided towards round brush for air outlet and sets referring to fig. 2
It sets, while being set as slim-lined construction.More preferably technical effect can be reached in this way, the technology that more can sufficiently solve in the application is asked
Topic.
In certain embodiments, in order to improve out the uniformity of outlet air, the quantity of air outlet 15 is 2 or more, and segmentation is got over
More, outlet air is more uniform.In view of the volume of sweeping robot and the length of platform 14, preferably, the quantity of air outlet 15
It is 3, referring specifically to Fig. 2.
In certain embodiments, referring to Fig. 3-Fig. 4, air outlet 15 is connected with air-out passage 16, the inner cavity of air-out passage 16
It is gradually reduced towards air outlet, and direction is tilted towards scrubbing brush direction.The inner cavity of air-out passage 16, which reduces, can be improved out wind speed
Degree, the air drag of generation is accordingly larger, by tilting the direction of air-out passage 16 towards scrubbing brush direction, can reach outlet air
The purposes that mouth 15 is arranged towards round brush 12.Preferably, setting 3 for air outlet 15 simultaneously, design, on the one hand considers in this way
The volume of sweeping robot, on the other hand can guarantee that outlet air is uniform, while can also obtain biggish wind speed, mating reaction, energy
Reach excellent technical effect, and can be reduced unnecessary of ground dirt, influences cleaning ambient.
In certain embodiments, considering the irregularities of process mesorelief of sweeping the floor, scraping article 13 should have certain deformability,
There should be good rub resistance simultaneously.Preferably, scraping article 13 is made of rubber material.
By foregoing description, it should be determined that, the embodiment of the present invention provides a kind of ground with above structure simultaneously
Brush assemblies 1.
In certain embodiments, in order to reduce the height of sweeping robot, and reduce the overall volume of sweeping robot,
Suction inlet and air outlet 15 are separately connected on aspiration motor component 2, the outlet air air-flow of aspiration motor outlet air can be guided into and led to
Road 16, You Yitai aspiration motor realize two functions of dust suction and outlet air simultaneously, improve efficiency of energy utilization and reduce cost.
In certain embodiments, aspiration motor component 2 includes motor housing 21, and the outlet air of motor housing 21 passes through wind conveying pipe
22 connection air outlets 15.The ingenious outlet air function of having used motor housing 21 is arranged in this, greatly reduces corresponding manufacturing cost.
In certain embodiments, wind conveying pipe 22 and air outlet 15 are correspondingly connected with, so that quantity is the same as 15 quantity phase of air outlet
Together, increase the uniformity of outlet air.In view of the volume of sweeping robot and the length of platform 14, preferably, wind conveying pipe 22
Quantity with air outlet 15 is 3.
Certainly, the invention is not limited to above embodiment, and those skilled in the art are without prejudice to originally
Equivalent deformation or replacement can be also made under the premise of spirit, these equivalent variation or replacement are all contained in the application right
It is required that in limited range.
