Problems solved by technology

However, tests have shown that such support of the former sealing lip cannot be prevented in motor-driven carpet brushes with a chassis: when the chassis of the carpet brush is lifted from the floor, the suction nozzle is vacuum-fixed on the floor during the return stroke.
In the intuitive operation of floor cleaners or suction pipes with connected electric carpet brushes, this can hardly be avoided due to the low gravitational forces acting on the chassis
Although the supporting effect can be enhanced by increasing the inflexible supporting profile, this also leads to the profile wearing down on the floor, which can lead to wear marks or floor damage

Embodiment Construction

[0022] attached figure 1 The motor-driven brush 1 is shown in , and the brush is determined to be an accessory of the vacuum cleaner. The brush 1 can be used in particular for cleaning carpets, upholstered furniture or mattresses. A brush or felt brush 1 has a housing 2 on which a pipe connection support 3 is hingedly mounted. The pipe connection support 3 can also be called a joint piece. A suction channel is formed in the housing 2, which is connected to a brush chamber which also serves as a suction opening. At least one brush body is accommodated in the brush cavity, and the brush body is driven by a transmission mechanism through an electric motor arranged in the housing 2 . The at least one brush body is typically embodied as a brush roller (round brush). The brush cavity (suction opening) is correspondingly shaped tunnel-like. The suction opening or the brush chamber extends almost over the entire length of the housing 2 .

Abstract

The invention relates to a device for a cleaning device having a suction blower. The device is provided with a suction inlet, which has a sealing lip (5) and a hairbrush (8) that are made from rubber elastic mateirals and are arranged on a connector (6) stretched along the suction inlet, and the connector (6) is installed in a shell (2) having the suction inlet. The device can be a hairbrush driven by a motor and any other ground suction nozzle of a dust collector. According to the invention, the sealing lip (5) is supported by the hairbrush (8), so taht inclination of the suction inlet relative to the sruface of floor or vacuum-fixation of the suction inlet on the to-be-cleaned floor; herein, the hairbrush (8) has one or more hair-free zone (9, 9') along the sealing lip (5), thus satisfied absroption of coarse stains is ensured even through the hairbrush (8) for supporting the selaing lip.

Description

technical field [0001] The invention relates to a device for a cleaning appliance with a suction blower, the device having a suction inlet provided with a sealing lip made of rubber elastic material and a brush row, wherein the connection extending along the suction inlet The sealing lip and the brush row are arranged on the connecting piece, and the connecting piece is installed in the shell with the suction port. This device is, for example, a motor-driven brush or any other floor nozzle of a vacuum cleaner. Furthermore, the device can also be a component of a cleaning robot. Background technique [0002] Suction cleaning devices, such as vacuum cleaners, are known in the prior art, which have a suction head with an elongated suction opening. Many such cleaning devices are provided with sealing lips and / or brush rows on the suction opening in order to improve the cleaning effect of the associated device. [0003] In order to prevent the sealing lip of the floor suction ...
