Painting device with a manual suction cylinder

Abstract

A painting device with a manual suction cylinder is provided with a connecting cavity or a connecting cylinder at each of its guiding pipe, brush heads and handle, with the connecting cylinder and the connecting cavity, the guiding pipe, the handle and the brush head are allowed to be assembled and disassembled quickly and easily, and a single handle of the present invention can be used to easily connect different types of brush heads without having the conventional problem that the conventional brush heads must have its own handle.

1 . A painting device with a manual suction cylinder comprising a guiding pipe, a handle, and at least one brush head, the manual suction cylinder including a suction head and a container, the container being provided for storage of paint, pressing of the suction head causing the paint to be sucked from the container and discharged from a nozzle which is located at one end of the suction head, the guiding pipe including a first end and a second end, and the first end being connected to the nozzle of the suction head, the handle including a feeding end and a discharge end which are connected together by a passage, the brush head including a connecting end connected to an interior of the brush head by a passage, and the brush head being connected to the discharge end of the handle via a connecting end, so that the paint is sucked from the manual suction cylinder to the brush head via the guiding pipe and the handle; the painting device characterized in that:
 a hollow connecting cylinder formed with two opposite protrusions on its outer surface; a connecting cavity, inside the connecting cavity are formed two opposite engaging grooves, and at one side of the engaging grooves is formed a positioning groove; when the connecting cylinder is inserted in the connecting cavity, the protrusions are firstly engaged in the engaging grooves and then rotate together with the connecting cylinder within the connecting cavity by a certain distance and finally slide into a locked positioned in the positioning groove, rotating the connecting cylinder and the connecting cavity in opposite directions can make the protrusions slide out of the positioning grooves, so that the connecting cylinder is allowed to be disengaged from the connecting cavity; the hollow connecting cylinder and the connecting cavity are formed at the connecting end of the brush head, the second end of the guiding pipe and the discharge end of the handle; with the connecting cylinder and the connecting cavity, the guiding pipe, the handle and the brush head are allowed to be assembled and disassembled.
