DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of a drainage cleaning tool according to the present invention will be described in detail with reference to the drawings. The cleaning tool shown in FIGS. 1 to 3 has a pair of sandwiching arms 1 and 1 that can be opened and closed in a tweezers manner by connecting base end portions to each other by an elastic connecting portion 2. At the front ends of the sandwiching arms 1 and 1, a brush base 3 having a front end 3a bent in a hook shape in a direction parallel to each other is formed. The brush base 3 is provided with a brush 4 for removing dirt. Along with the bowl-shaped shape of the brush table 3, it is implanted so as to have a hair tip surface 5 partially different in direction, and a projection 6 for picking up dust is formed. In this cleaning tool, the other parts excluding the brush 4 are integrally formed of synthetic resin.
[0011]
The holding arms 1 and 1 are formed in an L-shaped cross section as shown in FIG. 4 in order to maintain strength, and the brush table 3 at the tip thereof is formed in a semicircular cross section as shown in FIG. The flat side surfaces 3b are directed to the inside of the arm so as to face each other. The brush 4 is planted on the outer peripheral surface of the brush base 3 which is bent. For this reason, the hair tip surface 5 of the brush 4 is bent in a shape along the saddle shape of the brush table 3. In the illustrated example, the hair tip surface 5 has a first hair tip surface 5a located in a plane substantially parallel to a plane including the axis of the two sandwiching arms 1 and 1, and the first hair tip surface 5a. It is divided into the 2nd hair end surface 5b orthogonally crossed. In this case, the portion where the first hair end surface 5a and the second hair end surface 5b are continuous may be corners, but the corners may be eliminated by rounding or cutting linearly.
[0012]
The brush 4 has a plurality of bundles of fiber bundles 4a arranged in two rows along the outer peripheral surface of the brush table 3, and an angle is provided between them so that the hair tip surface 5 extends left and right. In order to prevent the brushes from colliding with each other when the sandwiching arms 1 and 1 are closed, the fiber bundle 4a in the inner row is directly below and It is desirable to plant the plant in a straight line in the direction of the front and plant the fiber bundles 4a in the outer row in an inclined state toward the outside. However, the form of the brush 4 is not limited to this.
[0013]
Further, the protrusion 6 has a diameter smaller than that of the brush table 3 and extends in a direction substantially perpendicular to the axis of the holding arm 1 at a position closer to the inside of the tip of the brush table 3. The tip of the projection 6 is slightly inclined inward so as to securely grasp hair or the like.
[0014]
When cleaning the drainage port with the drainage cleaning tool having the above-described configuration, the sliding material adhering to the rim portion, the inner peripheral surface, the grating, etc. of the drainage port is parallel to the clamping arms 1 and 1 of the brush 4. The sliding substance scraped off by the first hair end surface 5a and adhered to the upper surface of the stepped portion in the opening or the like is scraped off by the second hair tip surface 5b facing the front of the tip of the sandwiching arm 1,1. Further, dust such as hair entangled with the grating is removed by pinching the projections 6 and 6 protruding from the tips of the brush bases 3 and 3 with the direction of the cleaning tool turned upside down.
[0015]
In this way, by using different hair tip surfaces 5a and 5b with different directions of the brush 4 depending on the object to be cleaned, even the rim portion, inner peripheral surface, stepped portion in the hole, etc. It is possible to easily and reliably remove the slipping substance attached to the surface, and it is also possible to easily remove dust such as hair entangled with the grating simply by changing the direction of the cleaning tool.
[0016]
【The invention's effect】
As described above, according to the present invention, it is possible to remove slipping substances adhering to the rim portion of the drain outlet, the inner peripheral surface, or the stepped portion in the opening with one cleaning tool, and to remove dust such as hair entangled with the grating. Removal can be performed easily and reliably, and it is functional and excellent in workability.
