In order to learn technical content, purposes and functions of the present invention more clearly and completely, please refer to the following detailed descriptions with the figures and reference signs.
Refer to
The outer tube 1 is a hollow tube having a bottom end connected with a top end of the suction cup body 2 and a top end on which the hair cleaner 3 is disposed.
The suction cup body 2 consists of a cup-shaped body 21, a circular positioning segment 22 integrally connected with a bottom edge of the cup-shaped body 21, and a protruding ring 23 integrally connected with and radially projecting outward from a junction between the cup-shaped body 21 and the circular positioning segment 22. The circular positioning segment 22 is step-like and a diameter of an upper step is larger than a diameter of a lower step.
The hair cleaner 3 is composed of a handle 31, a flexible rod 32 integrally connected with the handle 31 and extending downward, a plurality of barb sets 33 projecting from a surface of the flexible rod 32, at least one insertion hole 34 arranged at the flexible rod 32 and penetrating the flexible rod 32, and a spike 35 having a root end connected with a bottom edge of the insertion hole 34 and a sharp free end located opposite to the root end. Each of the barb sets 33 is provided with a plurality of barbs 331. The flexible rod 32 of the hair cleaner 3 is inserted through and mounted in the outer tube 1. A bottom end of the handle 31 of the hair cleaner 3 is fixed and connected with the top end of the outer tube 1 when the flexible rod 32 of the hair cleaner 3 is inserted and mounted in the outer tube 1.
In a preferred embodiment, the barb sets 33 are arranged at two sides of the flexible rod 32 in a staggered manner.
In a preferred embodiment, a plurality of sharp projections 36 extending backward is disposed on a tip of the flexible rod 32.
In a preferred embodiment, the bottom end of the outer tube 1 is provided with a first outer threaded segment 11 while the top end of the cup-shaped body 21 of the suction cup body 2 is mounted with an inner threaded hole 24. Thereby the outer tube 1 and the suction cup body 2 are connected by the first outer threaded segment 11 and the inner threaded hole 24 threaded with each other correspondingly.
In a preferred embodiment, a second outer threaded segment 37 is mounted to the bottom end of the handle 31 while an inner threaded segment 12 is arranged at an inner wall surface of the top end of the outer tube 1. By the second outer threaded segment 37 and the inner threaded segment 12 threaded with each other, the flexible rod 32 of the hair cleaner 3 inserted through and mounted in a hollow space of the outer tube 1 is fixed. And the hair cleaner 3 is not easily separated from the outer tube 1.
While in use, users can use either the hair cleaner 3 or the suction cup body 2 according to their needs. When the hair cleaner 3 is used, the second outer threaded segment 37 of the hair cleaner 3 and the inner threaded segment 12 at the inner wall surface of the top end of the outer tube 1 are separated from each other and the hair cleaner 3 is taken out of the outer tube 1. Then hold the handle 31 and place the hair cleaner 3 into flush or water pipes from the tip of the hair cleaner 3. Next hair and dirt inside the pipes are removed by the barbs 331 of the bar sets 33 exactly (as shown in
While using the suction cup body 2 to unclog the flush pipes, the circular positioning segment 22 on the lower part of the suction cup body 2 is mounted into a toilet correspondingly. By the circular positioning segment 22 being matched with an inner surface of the toilet through the steps of the circular positioning segment 22, a larger pressure difference is generated when a pressure is applied and the cup-shaped body 21 is deformed for delivering air into the flush pipes. This helps the blockage or dirt move away from clogged area and the pipes are free of clogs.
