Embodiment Construction

[0050] Figure 1 to Figure 5 A vacuum cleaner nozzle 2 is shown, comprising a connection sleeve 3 to which is connected a joint of a rigid or flexible tube, which itself is connected to a suction system (not shown) of the vacuum cleaner. There are already different types of vacuum cleaners on the market that can be used with the vacuum cleaner nozzle 2 according to the invention; since these different types of vacuum cleaners are known to those skilled in the art, they are not described in detail in this patent application.

[0051] The suction nozzle 2 of the vacuum cleaner also includes an upper cover 4 and two displacement wheels 5, and the displacement wheels 5 are mounted on the upper cover 4 and are configured to roll on the ground to be cleaned. The two displacement wheels 5 are each advantageously located on the respective side of the upper cover 4 and the connecting sleeve 3 .

[0052] The connecting sleeve 3 is mounted to be pivotally connected to the upper cover 4 ...

Abstract

The invention relates to a suction nozzle of a dust collector. The device comprises a bottom plate (6), wherein the bottom plate (6) is provided with a lower surface (7) and a suction port (8) which is opened on the lower surface (7); the bottom plate (6) comprises a rear scraping rib (11); the rear scraping rib is used for scraping the ground to be cleaned and protrudes out of the lower surface (7). The lower surface (7) comprises a rear sliding surface (13) and a front sliding surface (14) which are located on the two sides of the suction opening (8) and are basically planar. The rear sliding surface (13) is adjacent to the rear scraping rib (11) and is positioned behind the rear scraping rib (11); the lower surface (7) further comprises a rear chamfered surface (17) extending in the continuation of the rear sliding surface (13) and being substantially planar, the rear chamfered surface (17) forming an inclination angle of between 1 and 4 degrees with respect to the rear sliding surface (13).

Description

technical field [0001] The present invention relates to the field of vacuum cleaners equipped with vacuum cleaner nozzles (also referred to as suction heads) and used to extract dust and small particle size wastes present on surfaces. Background technique [0002] Vacuum cleaners equipped with suction nozzles are well known in the market, and such vacuum cleaners can clean surfaces by suction to remove dust and small particle size waste left on the surface. The surface to be vacuumed can be eg tile, parquet, laminate, carpet or rug. [0003] A vacuum cleaner nozzle conventionally includes a connecting sleeve and a base plate, the base plate is equipped with a lower surface and a suction opening, the suction opening communicates with the connecting sleeve and opens on the lower surface of the base plate. During use of the vacuum cleaner nozzle, the lower surface of the soleplate is intended to be positioned snugly on the surface to be vacuumed. [0004] The bottom plate of ...
