A face support strip, fixedly connected to the mask surface, is arranged parallel to the inner side of both plastic frames. An ear loop is provided on one side of each plastic frame via a mating protrusion, and an adjustment block is installed on the ear loop. A first strap and a second strap are respectively provided at the top of the two ear loops. A buckle is provided at the top of the first strap, and a fixing strip matching the buckle is provided at the top of the second strap. This utility model, by symmetrically arranging two plastic frames on both sides of the mask surface and providing a face support strip fixedly connected to the mask surface parallel to their inner sides, creates a three-dimensional space inside the mask surface when unfolded, providing a more comfortable breathing experience when worn.

The utility model discloses an inner octagonal pipe belongs to pipe material technical field, including the pipe body of octagonal structure, the inner chamber of pipe body also is octagonal structure, the pipe body includes work section, flared connecting section and embedded connecting section, is equipped with the transition section between work section and flared connecting section, and flared connecting section and transition section are located one end of work section, and embedded connecting section is located the other end of work section, flared connecting section, transition section work section and embedded connecting section integrated molding.

The application provides a cleaning device and a cleaning equipment. The cleaning device comprises a device body, a rolling brush rotatably arranged on the device body, and a water outlet assembly arranged on the device body and configured to spray water on the rolling brush. The water outlet assembly comprises a receiving groove. A scraping assembly is arranged below the water outlet assembly and comprises a main plate, an adapter and an elastic member. The adapter is rotatably connected to the water outlet assembly or the device body. The main plate is divided into a first part and a second part by a rotation axis of the adapter. The first part is in interference contact with the rolling brush. The elastic member is in elastic abutment with the second part and the water outlet assembly to drive the second part away from the receiving groove. The application adjusts the inclination angle of the main plate by rotating the main plate driven by the rolling brush, so that the rolling brush can clean the dirt left on the surface of the main plate. When the rolling brush reverses, the contact pressure between the rolling brush and the main plate is reduced, thereby reducing the abrasion of the rolling brush fabric.
