Referring then to
It is to be noted that the connection of the brushes 12 to the pipe 11 is such that the pipe 11 is directly inserted onto the end of the brushes 12. In real application, the pipe 11 is very likely to become loose and disengage from the brushes after several times of assembly and disassembly. Moreover, the brushes 12 are relatively expensive and difficult to produce since each brush 12 has its own handle.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide improvements on the handle, guiding pipe and brush head of a painting device with a manual suction cylinder, wherein 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.
To achieve the above object, a painting device with a manual suction cylinder in accordance with the present invention comprises a guiding pipe, a handle, and at least one brush head, the manual suction cylinder including a suction head and a container. The suction cylinder is provided with a suction tube and a check valve, the suction tube is disposed in the container, the container is provided for storage of paint, pressing of the suction head causes 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 includes a first end and a second end, and the first end is connected to the nozzle of the suction head, the handle includes a feeding end and a discharge end which are connected together by a passage, the brush head includes a connecting end connected to an interior of the brush head by a passage, and the brush head is 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 is 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.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

The manual suction cylinder 20 comprises a suction head 21 and a container 22. Like the conventional structure, the suction head 21 of the present invention is also provided with a check valve and a suction tube (not shown). The container 22 is provided for storage of paint, and the pressing of the suction head 21 causes the paint to be sucked from the container 22 and discharged from a nozzle 211 which is located at one end of the suction head 21.
The guiding pipe 30 includes a first end 31 and a second end 32, and the first end 31 connected to the nozzle 211 of the suction head 21.
The handle 40 includes a feeding end 51 and a discharge end 42 which are connected by a passage 43.
The brush head 50 includes a connecting end 51 which is connected to the interior of the brush head 50 by a passage 52, and the brush head 50 is connected to the discharge end 42 of the handle 40 via the connecting end 51, so that the paint is sucked from the manual suction cylinder 20 to the brush head 50 via the guiding pipe 30 and the handle 40, as shown in
The characteristics of the present invention are described as follows:
Firstly, the connecting end 51 of the brush head 50 and the feeding end 41 of the handle 40 are each specially provided with a connecting cylinder 60 the outer surface which are formed with two opposite protrusions 61, and the connecting cylinder 60 is hollow inside.
Secondly, the second end 32 of the guiding pipe 30 and the discharge end 42 of the handle 40 are each formed with a connecting cavity 70, inside the connecting cavity 70 are formed two opposite engaging grooves 71, and at one side of the engaging grooves 71 is formed a positioning groove 72. If the connecting cylinder 60 is inserted in the connecting cavity 70, the protrusions 61 are firstly engaged in the engaging grooves 71 (as shown in
For a better understanding of the operation of the present invention, reference should be made to the following description.
Referring to
Referring then to
It is to be noted that it needs to use different brushes during painting, the handle 40 of the present invention is specially designed to have a connecting cavity 70, while the roller brush 53, flat brush 54, narrow brush 55 and wide brush 56 are all provided with a connecting cylinder 60, so that the handle 40 of the present invention can be easily connected to different types of brushes.
On top of that, the design of the structures of the connecting cavity 70 and the connecting cylinder 60 can change according to actual requirements. As shown in
With the abovementioned designs, a single handle of the present invention can be used to connect different types of brush heads without having the conventional problem that the conventional brush heads must have its own handle.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
