However, the above-described conventional cleaning tool for pipes has a wiping element made of a brush or sponge fixed to the main body, so it cannot be cleaned without reaching the wiping element in a winding pipe. Sometimes occurred.
An object of the present invention is to provide an in-pipe cleaning tool having high cleaning efficiency, in which there is almost no portion that cannot be cleaned because the sponge does not reach in cleaning in a winding pipe.

  As a result of intensive studies to achieve the above-mentioned object, the inventor comprises a long wire rod that is bent along the inner wall of the pipeline when inserted into the pipeline, and a sponge, The distal end of the wire is bent into a three-dimensional helix, and a portion of the sponge is inserted into an inner space surrounded by the wire bent into the three-dimensional helix, so that the sponge is inserted into the distal end of the wire. It was found that when the inside of a tortuous pipe line was cleaned using a pipe cleaning tool attached to the pipe, there was almost no part that could not be cleaned because the sponge did not reach, and the cleaning efficiency inside the pipe line increased. . The present invention has been completed as a result of further studies based on this finding.

That is, the present invention is as follows.
<1> a long wire that is bent along the inner wall of the pipe when inserted into the pipe;
Made of sponge,
The distal end of the wire is bent into a three-dimensional helix,
The sponge is attached to the distal end of the wire so that a part of the sponge is inserted into an inner space surrounded by the wire bent into the three-dimensional spiral shape,
Pipeline cleaning equipment.
<2> The in-pipe cleaning instrument according to <1>, wherein the sponge can be attached and detached by rotating the sponge along a three-dimensional spiral.
<3> The in-pipe cleaning instrument according to <1> or <2>, wherein a proximal end of the wire is bent into a bowl shape.
<4> The long wire rod is an in-pipe cleaning device according to any one of <1> to <3>, wherein the long wire has a lumen penetrating from a proximal end to a distal end.

Since the pipe cleaning device of the present invention merely inserts the sponge into the inner space surrounded by the wire that is bent into the three-dimensional spiral shape, it is possible to attach and detach the sponge, change the position and orientation of the sponge, It is possible to freely change to a sponge.
When a portion that cannot be cleaned because the sponge does not reach the cleaning in the winding pipeline, the corners in the pipeline can be cleaned by changing the attachment position and orientation of the sponge. Further, fluid such as water vapor and cleaning liquid can be supplied to the cleaning site through the lumen of the long wire rod. With the in-pipe cleaning tool of the present invention, it is possible to shorten the in-pipe cleaning time and improve the cleaning effect.

It is a figure which shows one Embodiment of the in-pipe cleaning instrument of this invention.

  The in-pipe cleaning tool of the present invention will be specifically described with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the in-pipe cleaning tool of the present invention. The embodiment shown in FIG. 1 is an example of the present invention. The present invention includes modifications, additions or modifications that do not impair the object and function of the present invention.

The in-pipe cleaning tool shown in FIG. 1 includes a long wire 1 and a sponge 2.
The wire 1 is not particularly limited as long as it is formed of a material that does not corrode or deteriorate in an environment where the cleaning tool is used. For example, those made of a resin such as polyamide, polyester, polyvinyl chloride, fluororesin, or silicone resin, or a metal such as aluminum or stainless steel are preferred, and those made of a resin are preferred. In the case of a resin wire, a reinforcing material may be included in the wire.

  The wire 1 is made to bend along the inner wall of the pipe when inserted into the pipe. By having such flexibility, it becomes possible to clean every corner in the pipe. The wire may be a monofilament or a twist of a plurality of filaments.

The outer diameter of the wire is not particularly limited, but is usually 1.5 to 3.0 mm. If it is too thick, the flexibility tends to decrease, and if it is too thin, the operability tends to decrease.
The length of the wire is not particularly limited, but is usually 30 to 50 cm. If it is too long, the operability tends to decrease. If it is too short, it is not suitable for cleaning long pipes.

It is preferable that the wire 1 has a lumen penetrating from the proximal end to the distal end. Fluid can flow through the lumen. Examples of the fluid include gases such as dry air and water vapor, and liquids such as a cleaning liquid and a rinsing liquid. The fluid can be supplied to the cleaning site through the lumen.
The inner diameter of the lumen can be appropriately selected according to the outer diameter of the wire. When a lumen is provided for the purpose of flowing a fluid, it is preferable that the inner diameter is such that pressure loss does not become excessive. The inner diameter of the lumen is usually 1.5 to 2.0 mm.

  The sponge 2 is a porous soft material having countless fine pores inside. The sponge may be a natural sponge processed from aquatic sponges, but is preferably an artificially manufactured synthetic sponge from the viewpoint of strength and the like. Examples of the synthetic sponge include polyurethane sponge, melamine sponge, and rubber sponge. When rubbed with a small amount of water, the melamine sponge can remove dirt while wearing the surface like an eraser. The rubber sponge can be appropriately selected according to the material of the pipe to be cleaned because the adjustment range of the hardness can be greatly changed by a combination of a rubber material and a foaming agent.

  Although the magnitude | size in particular of sponge 2 is not restrict | limited, It is preferable that it is larger than the magnitude | size of the inner space enclosed by the solid spiral of the wire rod distal end mentioned later. The shape of the sponge 2 is not particularly limited. For example, a rectangular parallelepiped, a cube, an ellipsoid, a sphere, etc. are mentioned. Moreover, you may have an uneven | corrugated shape corresponding to the solid helical shape of a wire rod distal end.

  The distal end of the wire is bent into a three-dimensional spiral. The three-dimensional spiral is a curved shape drawn by a morning glory vine or a screw mountain or valley. In the three-dimensional helix, only a circle of almost the same size is drawn repeatedly as seen from the direction of the axis, but the shape changes in height, or a curved shape engraved on the shell of the snail Examples include a conical spiral shape and a combination of these. When viewed from the direction of the axis, the conical spiral is a shape in which the line gradually moves away from the center, the radius of curvature increases, and the height changes at the same time. The spiral may be right-handed or left-handed.

  In the in-pipe cleaning tool of the present invention, the sponge is attached to the distal end of the wire so that a part of the sponge is inserted into the inner space surrounded by the wire bent into the three-dimensional spiral shape. . The sponge is attached to the distal end by inserting the sponge into the inner space surrounded by the wire bent into the three-dimensional spiral shape. The inserted sponge may be fixed with an adhesive or the like, but it is preferable to simply insert it without fixing. When the sponge is attached to the distal end of the wire without being fixed, the sponge can be freely attached and detached by rotating the sponge along the spiral. Further, the position and orientation of the sponge can be changed according to the shape of the pipe line to be cleaned. Furthermore, a dirty sponge can be easily replaced with a new one by use.

  In the in-pipe cleaning instrument of the present invention, it is preferable that the proximal end of the wire is bent into a bowl shape. The shape of the bowl shape is not particularly limited, and may be, for example, a J shape as shown in FIG. 1, an L shape, a ρ shape, or the like. By being bent into a bowl shape, it becomes easy to hold and operate the cleaning tool by hand. Further, since the hook shape is caught at the edge of the entrance of the pipeline, it is possible to prevent the cleaning tool from being accidentally dropped out of reach of the pipeline.

  According to the in-pipe cleaning tool of the present invention, the inside of the pipe can be cleaned in a short time and with a high cleaning effect. The pipe to be cleaned by the in-pipe cleaning tool of the present invention is not particularly limited. For example, laboratory instruments such as glass tubes and test tubes; plumbing pipes such as water pipes, gas pipes, air conditioning pipes, sewage pipes and exhaust pipes in factories, homes and offices; wind instruments such as trumpets, recorders and flutes; endoscopes, etc. Medical devices; smoking devices such as xels and pipes;
