[0024] The specific contents of the utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0025] See also Figure 1-6 As shown, the utility model provides a new type of shovel-type T-shaped scraper strip, including a scraper strip main body 1, a roller brush mounting seat 2 is installed at the bottom of the sweeper main body 3, a cleaning roller brush assembly 4 and the scraper strip main body 1 are installed in the roller brush mounting seat 2, the cleaning roller brush assembly 4 is rotatably installed in the roller brush mounting seat 2, an opening 21 is provided at the bottom of the roller brush mounting seat 2, the upper end of the scraper strip main body 1 is detachably mounted at the edge of the opening 21, the lower end of the scraper strip main body 1 extends obliquely downward until it contacts the ground, and the lower end of the scraper strip main body 1 is provided with a T-shaped shoveling edge structure 11.

[0026] Furthermore, the scraper strip body 1 is made of a wear-resistant and corrosion-resistant elastic material. Currently, the scraper strips of sweepers are mostly made of soft materials, such as soft rubber, to reduce friction and noise with the ground. In addition, there are also scraper strips made of special materials, such as materials with wear-resistant and corrosion-resistant properties, to increase the service life of the scraper strips.

[0027] Furthermore, in order to achieve a better cleaning effect by the T-shaped shovel edge structure 11, the T-shaped shovel edge structure 11 at the lower end of the scraper strip body 1 includes a first end 111, a second end 112, and a third end 113, wherein the second end 112 and the third end 113 are respectively arranged on the left and right sides of the first end 111. The first end 111, the second end 112, and the third end 113 intersect to form a T-shaped structure. When the sweeper body 3 is in the backward state, the first end 111 of the scraper strip body 1 is set in contact with the ground. When the sweeper body 3 is in the forward state, the scraper strip body 1 is bent so that the first end 111 and the second end 112 are simultaneously set in contact with the ground. When the scraper strip body 1 is bent, the third end 113 stands on one side of the back of the second end 112, which can improve the support strength of the first end 111 and the second end 112, and avoid excessive deformation of the first end 111 and the second end 112, which affects the cleaning effect of the shovel strip.

[0028] Furthermore, a sloped surface is provided on the edge of the opening 21 of the roller brush mounting seat 2, and the inner side surface of the lower end of the scraper strip main body 1 is arranged to fit the sloped surface. A first groove structure 12 is also recessed at the connection between the lower end and the upper end of the scraper strip main body 1, and a first protrusion 22 is provided on the upper edge of the sloped surface of the opening 21 of the roller brush mounting seat 2, and the first protrusion 22 and the first groove structure 12 are engaged with each other.

When the sweeper moves backward, dust and other garbage will not be scraped away. It will remain on the ground and will be scraped away when the main machine moves forward.

[0032] When the sweeper moves forward to clean, the scraping blade rubs against the ground and deforms, causing the first end 111 of the T-shaped scraping edge structure 11 to bend backward and deform, and the second end 112 to fit the ground, so that the upper surface of the second end 112 forms an inclined surface. At this time, dust, particles and other garbage are scraped away by the scraping blade and accumulated at the dust suction port along the direction of the roller brush rotation. They are then carried into the dust box along the direction of the dust suction fan.

[0033] The connection between the scraper strip body 1 and the roller brush mounting base 2 adopts an easy-to-disassemble design, which is convenient for users to regularly replace or clean the scraper strip to maintain cleaning efficiency.
