STICK FOR MECHANICAL CLEANING OF PIPES

Abstract

The invention relates to a stick for the cleaning of household wastewater pipes, designed to be immobilized in the inlet of the pipe and to dissolve, under the action of the water, and release a cleaning agent. It is designed to perform mechanical cleaning in addition to the action of the agent. In order to do this, the stick is rotated under the action of the water, for example by virtue of a helicoidal relief (2) or of rotary vanes (5) on its wall.

Claims

1. Household stick (1; 10; 30; 40) for the cleaning of household drainage wastewater pipes designed to be blocked at the inlet of the pipe, in order to dissolve under the action of the water and release a cleaning agent and, in addition to the action of the agent, to perform a mechanical cleaning, the stick being characterized in that it is designed to be rotated under the action of the water.

2. The cleaning stick (1; 10) according to claim 1, comprising a helicoidal relief (2; 3) on its wall.

3. The cleaning stick (40) according to claim 1, comprising rotary vanes (5).

4. The cleaning stick (30) according to claim 1, comprising scraping means (4).

Description

BRIEF DESCRIPTION OF THE FIGURES

[0014] The invention will be better understood with the aid of the following detailed description, made with reference to the drawing found in the appendix, in which:

[0015] FIG. 1 is a front view of a first embodiment of the stick of the invention;

[0016] FIG. 2 is a front view of a second embodiment of the stick of the invention;

[0017] FIG. 3 is a front view of a third embodiment of the stick of the invention and

[0018] FIG. 4 is a front view of a fourth embodiment of the stick of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0019] As shown in FIG. 1, the cleaning stick 1 is a thin stick of general cylindrical shape. Said stick comprises a helicoidal relief. This helical relief is made using, here, a rib 2 on the outer surface of the stick, which could also include several ribs.

[0020] In FIG. 2, the helical shape is realized here by a groove 3 hollowed on the surface of the stick.

[0021] The stick comprises chemical or biological active agents, on a polymeric support, whose purpose is to break down grease and residues found in the pipes. These active agents can be of any type.

[0022] In addition, barbs 4 are also provided on the surface of the stick 30 for scraping the walls of the siphon, as illustrated in FIG. 3.

[0023] It may be envisaged that the barbs be replaced by a rough surface or other elements to scrape the surfaces of the siphon.

[0024] The cleaning stick is placed, for example, in a drainage plug of a sink and is blocked in the siphon by virtue of its elongated shape. Following the flow of water on the stick, said stick rotates in the siphon by virtue of the helical shape of its relief. Indeed, the water will rush in between the ribs 2, causing the stick to turn on itself and to be pushed against the wall. A swirl in the siphon enhances the mechanical cleaning action. Indeed, this swirl of water provides cleaning by scraping the walls of the siphon. Moreover, the stick, made to rotate, also scrapes the wall of the siphon.

[0025] On the other hand, the stick of the invention retains its chemical cleaning action, by virtue of the active agents contained in this stick. These active agents are indeed released during the dissolution of the stick in the water. These active agents act on the grease and residues contained in the pipes.

[0026] The stick 40 of FIG. 4 comprises vanes 5. These vanes 5 cause the stick 40 to rotate in the siphon under the action of the water pressure.
