[0041] A driving component 5 , the first scraper strip 3 and the second scraper strip 4 are both connected to the driving component 5 , and the driving component 5 drives the first scraper strip 3 and the second scraper strip 4 to move.

[0042] The present invention provides a vacuum cleaner floor brush with intelligent double scraper strips, which mainly comprises a floor brush main body, to which a roller brush is rotatably connected; a scraper strip assembly, wherein the scraper strip assembly comprises a first scraper strip and a second scraper strip, wherein the first scraper strip and the second scraper strip are movably connected to the floor brush main body, wherein the first scraper strip is arranged on the front side of the roller brush, and the second scraper strip is arranged on the rear side of the roller brush; and a driving component, wherein the first scraper strip and the second scraper strip are both connected to the driving component, and the driving component drives the first scraper strip and the second scraper strip to move.

[0043] Through the arrangement of the above structure, the driving component can be used to drive the first scraper bar and the second scraper bar to swing, so that when the floor brush cleans the corner, the first scraper bar is lowered, and the garbage at the foot of the wall can be scraped away when the floor brush retreats. Before the cleaning is finished, the driving component pulls back to drive the second scraper bar to swing forward, which can drive the second scraper bar to tilt up and push large particles toward the suction port, so that the suction port can take away the large particles, thereby improving the cleaning efficiency.

[0044] Embodiment 2:

[0045] See also Figures 1 to 3 The present invention provides a vacuum cleaner floor brush with intelligent double scraping strips, comprising:

[0046] A floor brush body 1, to which a roller brush 2 is rotatably connected;

[0048] A driving component 5 , the first scraper strip 3 and the second scraper strip 4 are both connected to the driving component 5 , and the driving component 5 drives the first scraper strip 3 and the second scraper strip 4 to move.

[0049] When the floor brush is working, the first scraper bar is suspended in the air when the floor brush moves forward, and the second scraper bar is close to the ground, ensuring the entry of dust in the front of the floor brush. At the same time, because the second scraper bar at the rear is close to the ground, it can ensure a large vacuum degree of the floor brush and push the missed dust into the suction port. When the floor brush moves backward, the second scraper bar is suspended in the air and the first scraper bar is close to the ground, which can scrape out the dust in the front, especially the dust in the front of the wall that the roller brush could not reach before, thereby improving the cleaning quality.

[0050] The floor brush body 1 is provided with a large wheel forward and backward rotation detector, and the large wheel forward and backward rotation detector is connected to the driving component 5 .

[0051] By installing a large wheel forward and backward rotation detector in the floor brush body, when the floor brush is pulled forward and pushed backward, when the large wheel forward and backward rotation detector detects that the large wheel is rotating, the PCB receives a signal and powers on or off the driving component. The driving component drives the first scraper bar and the second scraper bar to swing back and forth, thereby improving the cleaning efficiency.

[0052] Embodiment three:

[0065] A driving component 5 , the first scraper strip 3 and the second scraper strip 4 are both connected to the driving component 5 , and the driving component 5 drives the first scraper strip 3 and the second scraper strip 4 to move.

[0066] When the floor brush is working, the first scraper bar is suspended in the air when the floor brush moves forward, and the second scraper bar is close to the ground, ensuring the entry of dust in the front of the floor brush. At the same time, because the second scraper bar at the rear is close to the ground, it can ensure a large vacuum degree of the floor brush and push the missed dust into the suction port. When the floor brush moves backward, the second scraper bar is suspended in the air and the first scraper bar is close to the ground, which can scrape out the dust in the front, especially the dust in the front of the wall that the roller brush could not reach before, thereby improving the cleaning quality.

[0073] When the floor brush is working, the first scraper bar is suspended in the air when the floor brush moves forward, and the second scraper bar is close to the ground, ensuring the entry of dust in the front of the floor brush. At the same time, because the second scraper bar at the rear is close to the ground, it can ensure a large vacuum degree of the floor brush and push the missed dust into the suction port. When the floor brush moves backward, the second scraper bar is suspended in the air and the first scraper bar is close to the ground, which can scrape out the dust in the front, especially the dust in the front of the wall that the roller brush could not reach before, thereby improving the cleaning quality.
