Embodiment Construction

[0117] figure 1An advantageous embodiment of the spraying device according to the invention, which is designated in its entirety by the reference numeral 10 , is shown in a perspective view. The spraying device 10 is designed as a spray gun 12 which can be held by the user's hand and can be manually actuated. In the present case, the spraying device 10 comprises a handle device with a handle element 14 which can be grasped by the user, the axis defined by the handle element 12 being oriented at an angle to the axis defined by the spray head 16, whereby the spray gun 12 acquires its shape .

[0118] At present, the angle between the handle element 12 and the spray head 16 is about 120° (which is based on the greater of two angles resulting from the intersecting axes). The spray head 16 protrudes from the handle element 14 in only one direction.

[0119] The spraying device according to the invention can be designed in different types, it does not have to be a spray gun. For...

Abstract

The invention relates to a spraying device for spraying a liquid, in particular in the low-pressure range, said spraying device (10; 90; 110; 40; 160; 170; 190; 220) being designed to be manually holdable and manually operable and comprising: a spray head (16) and a handle element (14); a fluid line (26; 92; 172) having an inlet (34) for supplying the liquid and an outlet (40) positioned on the spray head for spraying the liquid; an actuating element (30) for acting on a valve element (28) via which the flow of liquid through the fluid line (26; 92; 172) can be optionally released or blocked;and a preferably electric drive device (52) having a drive motor (54) which is coupled to the fluid line (26; 92; 172), wherein the fluid line (26; 92; 172) can be moved continuously in a defined manner via the drive device (52) in order to change the position and / or the orientation of the outlet (40).

Description

technical field [0001] The invention relates to a spraying device for spraying liquids, especially in the low-pressure range, designed to be hand-held and manually actuatable, comprising a spray head and a handle element, having an inlet for delivering liquid and for spraying liquid A fluid line of the outlet, an actuating element for influencing a valve element via which the passage of liquid through the fluid line can be selectively released or blocked. Background technique [0002] Such spraying devices can especially be used in house and garden areas, especially at a pressure range of about 0.5 bar to a maximum of 25 bar (currently regarded as a low pressure range, typically for example about 1 bar to 8 bar) of the liquid to be sprayed, wherein The liquid is water. Accordingly, the spraying device is in particular hand-held and manually actuatable and is designed, for example, as a spray gun. The user can hold the spray device on the handle element and control the disc...
