Description

The invention relates to the field of household appliances, in this case, nozzles for a vacuum cleaner, section A 47 L 9/00 IPC 7.

The applicant knows the analogue of the claimed invention, representing a nozzle for a vacuum cleaner containing a movable platform with lower rollers, known from the patent for utility model No. 36193 U1, publication date 03/10/2004.

The disadvantage of this analogue is the lack of an air gap between the treated coating (carpet) and the base (floor), which impairs air ventilation through the coating (carpet) and ultimately affects the quality of the dust assembly. The disadvantages include the even surface of the coating at the treatment site, when the deformation of the coating for greater openness of the carpet fabric may be the best option.

The task to which the invention is directed is to strengthen air ventilation through the treated coating (carpet) and deforming the surface of the carpet under the nozzle of the vacuum cleaner.

The technical result that is achieved in this invention is the creation of an air gap between the carpet and the floor at the place of dust collection, which improves ventilation through it and deforms the surface of the carpet to reveal its fabric.

The claimed technical result is achieved in that the nozzle consists of the upper part of the nozzle located, as usual, on the surface being cleaned (on the carpet), and a movable platform located under the surface being cleaned (carpet). The movable platform is placed under the carpet, can freely move under it after the movement of the upper nozzle, and thus creates an air gap under the carpet at the dust collection point.

The movable platform contains three or more pairs of freely rotating rollers, upper and lower, pairwise or separately mounted on curved upper and / or lower ends of the vertical axes. It is best to bend the ends of the axes at right angles so that the axis of rotation of the rollers is perpendicular to the vertical axis. The axes themselves rotate freely in mountings (for example, in ball bearings) located on the platform. It is also possible to make rollers in the form of pairs of balls. In each pair, the balls are vertically stacked on top of each other and enclosed in rounded frames, respectively lower and upper, bonded to each other. Free movement of the nozzle platform in any direction under the carpet is provided by freely rotating upper and lower rollers rolling on the floor surface and on the inner surface of the surface to be cleaned (carpet).

In addition, for vibrational or shock impact on the carpet, it is possible to place vibrating elements on the movable platform of the nozzle, so that they adjoin the carpet from the back side. The impact on them is carried out by means of an alternating magnetic field, one or several sources of which (for example, electromagnets) are located on the top of the nozzle, and the vibrating elements themselves comprise a magnetic material, for example a ferromagnet. Also, some of the upper rollers of the movable platform can function as vibrating elements, for example, can be fixed to the elastic elements of the housing of the movable platform.

The top of the nozzle should have a shape covering the movable platform of the nozzle. For example, to have three or more bent pins, the ends resting on the floor, on which, for example, the rollers are placed.

To enhance the adhesion of the upper part of the nozzle and the movable platform to each other, the upper part of the nozzle may have sources of a constant magnetic field, such as electromagnets or magnets, and the movable platform of the nozzle may contain magnetic material, such as a permanent magnet.

For maximum deformation of the coating at the place of dust collection (to reveal its fabric) and for more uniform carpet matting of the movable platform, the upper rollers of the movable nozzle platform can be centered higher than at the edges.

Figure 1 presents a view of a movable platform. Figure 2 presents a schematic view of the upper part of the nozzle and the movable platform. Figure 3 presents a view of the upper part of the nozzle. Figure 4 presents a view of a movable platform, where the rollers are made in the form of pairs of balls 16, set on top of each other and fixed in the frame 17.

The movable platform 1 consists of at least three pairs of rollers, each of which consists of lower rollers 2 and upper rollers 3. These rollers sit and rotate freely on the curved end 4 of axis 5. The axles 5 of each pair also rotate freely in the mounts 6.

The movable platform 1, placed under the cover (carpet) 13, can freely move in any direction due to free rolling in any direction of the lower rollers 2 and upper 3, which is achieved by free rotation of the axis 5 in the mounts 6.

For vibration exposure to the carpet 13 on the moving platform 1 are placed vibrating elements 12, made, as shown in figure 2, as the upper rollers 2 of the moving platform 1 on the elastic elements 11 and incorporating magnetic material or, as shown in figure 4 made as separate elements of a moving platform. The upper part of the nozzle 1 is composed of an electromagnet 10 (figure 2).

The nozzle operates as follows. The upper part of the nozzle 7 is pressed from above through the carpet 13 to the movable platform 1. Under the carpet in place under the upper part of the nozzle, an air layer 14 is created. Under the carpet, the platform 1 moves after the upper part of the nozzle 7 due to its grasping shape, for example, using pins 8, resting on the base 15 with rollers 9 and grasping the movable platform 1. Also, to enhance the adhesion of the movable platform 1 and the upper part of the nozzle 7, the movable platform 1 is composed of magnetic material, and the upper part of the nozzle has a ma yarns / solenoid (electromagnet 10 in Figure 2) for creating a permanent magnetic field, attracting the movable platform 1 to the upper part of the nozzle 7. A vibratory impact on the carpet 13 is an electromagnet 10 by creating an alternating magnetic field, under the influence of which the vibrating elements 12 vibrates.
