Embodiment Construction

[0022] FIG. 1 shows a hand-held electric power tool 1 designed as a hammer drill 2 or hammer drill 2 . It has the design of a pistol due to the handle part 3 and a main part 4 extending at an angle to the handle part 3 and having a motor part and a transmission part. The transmission part includes an impact mechanism. The motor part forms a first functional part 5 and the transmission part forms a second functional part 6 , wherein a suction module 7 is arranged between the two functional parts 5 and 6 . The suction module 7 is designed as a disk element 8 with a thickness d. In the region adjoining the suction module 7 , the cross-sectional profile of the first functional part 5 is substantially identical to the cross-sectional profile of the disk element 8 . Furthermore, the cross-sectional profile of the region of the second functional component 6 adjoining the suction module 7 substantially corresponds to the cross-sectional profile of the suction module 7 , that is to s...

Abstract

The invention relates to a handheld electrical tool (1) in particular drill, rock drill or hammer drill. The said tool (1) has a first functional part (5) and a second functional part (6) where the parts are connected with one another by a suction module (7) of a separating device. The module has a negative pressure joint (24)for connecting with separator (17) taken down from the handheld electrical tool (1)and separating the worked material, wherein the module is set behind the separator (17) with respect to a suction air flow at the flow technique.

Description

technical field [0001] The invention relates to a hand-held electric power tool, in particular a drill, impact drill or hammer drill. Background technique [0002] The use of hand-held electric power tools, for example in the form of hammer drills, leads to the generation of cuttings material. In the case of diamonds, concrete, etc., this cutting material is particularly abrasive and also leads to contamination. It is therefore known to provide such hand-held electric power tools with a separating device in order to avoid contamination by suction-generated material (hereinafter referred to as machining dust). [0003] It is known to disengage devices associated with hand-held power tools which have a suction fan impeller which is driven via the power take-off shaft of the hand-held power tool. In addition, suction devices are known which have a suction fan impeller which is driven by a suction fan electric motor. The suction fan electric motor is supplied with the require...
