Description

Auxiliary cleaning scraper assembly driven by air pump and application method Technical Field The invention relates to the technical field of cleaning appliances, in particular to an auxiliary cleaning scraper component driven by an air pump and a use method thereof. Background In recent years, with the explosive growth of the smart home industry and the pursuit of high-quality living environments by users, smart cleaning devices such as household cleaning robots and floor washers have undergone rapid technical iteration and market popularization. Among the many cleaning technology routes, the friction type cleaning solution based on a rotating roller brush has become the mainstream configuration of the floor cleaning apparatus by virtue of its efficient stain removal capability. The core working mechanism of the device generally depends on the direct contact between the rolling brush component and the ground, and the wiping and entrainment of solid and liquid stains on the ground are realized by the mechanical friction force generated by the high-speed rotation of the rolling brush and the water flow or cleaning liquid. Although the cleaning ability of existing cleaning devices is relatively mature in open areas, there are still shortcomings. Since most of the roller brushes are of cylindrical design, the cross section thereof is circular. When facing the 90-degree internal corner where the two perpendicular walls intersect, the outer contour of the round rolling brush cannot be completely matched with the geometric shape of the right-angle vertex. The rolling brush can only contact with the tangent line of the wall surface by virtue of the cylindrical surface of the rolling brush, and cannot be deeply embedded into the vertex area of the corner. This geometrical mismatch results in a "cleaning dead zone" at the corner of the wall that is approximately triangular, which severely affects the experience and the actual cleaning performance of the cleaning device. In the current floor washing machine and the rolling brush type cleaning device, in order to clean a cleaning blind area of a cylindrical rolling brush, a cleaning scraper is generally arranged at the side edge or above the rolling brush. Most of the existing cleaning scrapers on the market are made of rigid materials or semi-rigid materials with limited deformability, and do not have certain adaptive deformability, and after long-term use, structural deformation can lead to the cleaning scraper failure, and because the cleaning scraper is often integrated in cleaning equipment, professional repair is often required, and the user experience is greatly influenced. Accordingly, it is desirable to provide an air pump driven auxiliary cleaning blade and method of use that address the above-described problems. Disclosure of Invention In order to solve the problems, the invention aims to provide the auxiliary cleaning scraper driven by the air pump and the using method thereof, wherein the air pump is used for inflating or exhausting air into the closed space to enable the scraper group to have enough rigidity and prevent hard collision and protect the structure, the cleaning equipment is simply installed outside to enable the scraper group not to interfere with the cleaning equipment during working and simultaneously have better maintainability, the vision sensor is used for monitoring the wall surface distance in real time and pre-judging the dead angle position, so that the rubber scraper can be accurately attached to the surface to be cleaned in good time, and the dead angle of the traditional cleaning device is solved.
