Abstract

The invention relates to devices for cleaning surfaces. The purpose of the invention is to improve the quality of cleaning. The device for cleaning surfaces comprises an end brush 2 disposed in the housing I with a shank located perpendicular to its plane in the geometric center. The drive of the brush 2 consists of a shaft 4 which is vertically mounted in the geometric center of the housing 1 and displaced relative to the axis of the shank and mounted on the shaft 4 of the carrier 5, having a longitudinal groove with a shank mounted therein. The shank is spring-loaded by the spring 7 relative to the base of the groove to ensure contact of the brush 2 with the inner surface of the housing 1. The housing 1 in cross section has the form of circles 9 which are connected by means of sections 8 of straight arcs on the outside to form between them is a blunt angle. 2 Il.

This invention relates to surface cleaning devices.

The purpose of the invention is to improve the quality of surface cleaning.

i FIG. 1 shows a surface cleaning device, longitudinal section; in fig. 2 - the same, bottom view.

The device for cleaning the surface contains a face-E (placed brush 2 with a shank 3 located perpendicular to its plane in the Neometric center) placed in the housing 1, and a brush 2 leading from the vertically installed in the geometric center of housing 1 and displaced south with respect to the axis of the shank 3 of the shaft 4 and the carrier 5 mounted on the shaft, having a longitudinal groove 6 with an E installed; a shank 3 spring-loaded 7 with respect to the groove base to ensure that the brush 2 contacts the inner surface of the housing 1. Cor Pus 1 in (the cross section has the shape of the mating libix with each other by means of sections 8 of straight arcs of circles 9, while sections

3 on the outside are located on the outside

4 formation between them obtuse angle.

The device works as follows.

When the shaft 4 rotates, the carrier 5 begins to rotate the brush 2 around the axis of the shaft 3. At the same time, the brush 2 is pressed against the inner surface of the housing 1, and due to the Traction forces between the brush 2 and the internal surface of the housing 1, the i OKpyr shank axis 3 and when moving

along the inner surface of the housing on the rectilinear section 8, cleaning is only due to the rotation of the brush 2 along the surface being cleaned. When moving on the inner surface of the housing 1 on the site 9 5 simultaneously with the rotation of the brush 2, the impact occurs due to the elastic, deformation of the spring 7.

Thus, the brush 2 performs simultaneously with the rotational movement 0 and sharply translational movements, which increases the efficiency of cleaning the surface.
