The description refers to an airless spraying device, in particular for paint, comprising a vessel to receive the medium to be sprayed, a spraying head (1) having a pump (4), a rise tube projecting in the inside of the vessel and a drive device having an electric motor (5) for the pump. The vessel is a common disposable spray can (2) with an integrated shut-off valve (12). The spray head (1) forms, together with the drive unit (5, 20, 21, 22), a single unit which can be clamped onto the common disposable spray can (2) and has a handle (6) to which a holding device (30, 32) receiving the disposable spray can (2) can be joined, through which the disposable spray can (2) is pressed against a trigger pin (11) provided on the spray head, thus opening the shut-off valve (12) and creating the connection to the pump (4).
