The driving component 31 is an electric cylinder or a push-pull solenoid valve. The driving component is specifically a push-pull solenoid valve. 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 to power on or off the push-pull solenoid valve. The solenoid valve is attracted, and the connecting rod will extend and retract to drive the scraper to swing forward and backward, thereby improving the cleaning efficiency.

[0063] Working principle: When the floor brush is pulled forward and pushed backward, when the large wheel rotates forward and backward, the detector detects that the large wheel is rotating. After receiving the signal, the PCB will energize or de-energize the push-pull solenoid valve. The solenoid valve is attracted, and the connecting rod will extend and retract to drive the scraper bar to swing forward and backward, thereby improving the cleaning efficiency. By setting the front scraper bar body in front of the suction port on the floor brush, the front scraper bar body is close to the ground when the floor brush moves backward, so that the dust in the front, especially the dust in the front part that the roller brush cannot sweep against the wall before, can be scraped out and sucked into the floor brush, which can reduce the cleaning dead corners of the floor brush and improve the dust collection efficiency. The front scraper bar body consists of three parts: a scraper bar fixing seat, a pressure strip and a scraper bar. The scraper bar is clamped on the scraper bar fixing seat by a snap-on method, which is convenient for installing and disassembling the scraper bar. When the scraper bar is damaged, there is no need to replace the entire floor brush assembly, which reduces the cost of use for users. The pressure strip set can effectively resist the effect of the reaction force when the front scraper bar body is actuated.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
