[0025] As shown in Figures 2 to 5 The brush 100 includes a shell 1 and a roller cavity 2 formed by the shell 1, and the shell 1 is formed with a suction channel 3 to connect the suction device of the host 200 to the roller cavity 2, so that the roller cavity 2 is suctioned to form a negative pressure and the dirt is suctioned away; the roller cavity 2 is provided with a roller 4, and the bottom of the shell 1 is provided with a bottom opening 21 connected to the roller cavity 2, and the bottom opening 21 is used for suctioning the ground, and the roller 4 is in contact with the cleaning surface through the bottom opening 21, and the cleaning liquid device 300 provides cleaning liquid for the roller 4 to make it wet and wipe the stubborn dirt on the ground clean through high-speed rotation, and at the same time, the brush 100 has an automatic forward moving force driven by the high-speed rotation of the roller 4 to clean the ground. The edge of the bottom opening 21 is provided with a sealing rubber strip 5 to adhere to the ground to enhance the suction force on the ground; according to the direction of the brush 100, the sealing rubber strip 5 on the front side is divided into multiple sections, and the end of each section of the sealing rubber strip 5 can be deformed to open to form a dust suction inlet, through which the garbage and dust particles in front of the brush are first suctioned into the closed space formed by the bottom opening 21, avoiding being bounced out by the high-speed rotating roller 4, and then suctioned through the suction channel 3 to be recycled to the garbage can of the suction recovery device 201 to complete the cleaning work of the ground.

[0026] Compared with the structure design in the prior art, the suction force on the ground is enhanced, and the garbage can be more effectively collected, cleaned and suctioned through the dust suction inlet in front, which greatly improves the cleaning effect of the ground; at the same time, after enhancing the negative pressure suction force, the self-rolling roller provides the driving force for the brush to walk, making the user use more easily.

[0027] As a preferred scheme of the present application, the sealing strip 5 comprises a rear side scraping strip 51, left and right side edge sealing strips 52 and a front side transversely arranged multi-section sealing piece 53; the rear side scraping strip 51 can perform secondary scraping on the ground, and the slightly remaining water in the drum cavity 2 is scraped again and collected by suction, so that the cleaned ground becomes drier and easier to dry completely. A plurality of mounting tables 11 are arranged on the front side of the bottom of the shell 1, i.e. the front side of the bottom opening 21, and the sealing piece 53 is fixed on the mounting table 11. The plurality of mounting tables 11 can be integrally arranged on a support and mounted on the front side of the shell 1, which is more conducive to installation; and when the mounting table 11 is integrally formed by the support, the sealing piece 53 can be adhered to the mounting table 11 by a secondary injection molding process, which is faster and simpler to manufacture. Similarly, the rear side scraping strip 51 and the edge sealing strip 52 can also be manufactured into parts by a secondary injection molding process through an installation support component, and the rear side scraping strip 51 and the edge sealing strip 52 are adhered to the installation support component and assembled on the bottom of the shell 1 through the installation support component, so that it is simple and easy to arrange the sealing strip 5 on the bottom of the shell.
