Problems solved by technology

[0003] Known vacuum cleaner handpieces are too cumbersome and insensitive to handle with small or very small nozzles, especially in difficult-to-reach locations
In addition, the suction power can only be adjusted roughly and cumbersomely with conventional bypass valves

Embodiment Construction

[0021] The side view shown in FIG. 1 shows a cylindrical vacuum cleaner handpiece 10 . The vacuum cleaner handpiece is designed as a stepped cylinder on its front side 11 and has a plurality of bypass openings 14 there on its frontal area or on its stepped end face 12 . The bypass openings are arranged at an even distance from one another on a pitch circle below the outer circumference of the handle area 15 . In this case, the distance between the bypass openings 14 is at least as large as their width. The bypass openings are located outside the normal grip area of ​​the operator's hand and therefore cannot be accidentally or unintentionally closed by the hand while the vacuum cleaner handpiece 10 is being operated. As a result, the danger can be eliminated that the already selected, defined bypass parameters and thus the adjusted suction force are not inadvertently changed.

[0022] The vacuum cleaner handpiece 10 carries in the center of the front side 11 a nozzle tip 16 w...

Abstract

The present invention especially relates to a columned vacuum cleaner accessory tool, which includes a suction hole or a blow hole (17) disposed on the front (11) and an adapter (22) used for separably connecting a suction hose or a suction lead (40) on the back side. The accessory tool (10) has a middle handle area (15) and a replacing nozzle (16) by means of being designed to a nozzle adapter (18) of bayonet type adapter, wherein the nozzle constitutes the suction hole or the blow hole, thereby, the vacuum cleaner accessory tool can be used especially portably and versatilely.

Description

technical field [0001] The present invention relates to vacuum cleaner handpieces. Background technique [0002] Vacuum cleaner handpieces are known which are designed as spouts or nozzles which can be inserted exchangeably on the suction hose end piece. They differ with regard to the diameter and length of the suction or blow openings. In this case, the suction hose end piece serves as a handle and also carries a bypass opening, which is mostly continuously opened or closed. [0003] Known vacuum cleaner handpieces are too cumbersome and not very sensitive to handle with small or very small nozzles, especially at difficult-to-reach locations. Furthermore, with conventional bypass valves, only a cumbersome and rough adjustment of the suction force is possible. Contents of the invention [0004] According to the invention, a vacuum cleaner handpiece is proposed, in particular of cylindrical design, which has a suction or blow hole arranged on its front side and a suction...
