Abstract

PROBLEM TO BE SOLVED: To improve collection efficiency by expanding a collection area by forming the bottom surface of a support tool as the curvature part projecting in the central part and curving by forming a gentle arc toward the cleaning directional both end parts. SOLUTION: The bottom surface of a support tool 2 being a cleaning tool main body forms the curvature part 8 smoothly projecting downward in the central part 9 and curving by forming a gentle projecting circular arc toward the short part 10 in the cleaning direction A and the end part 11 in the cleaning direction B with continuing from there. When the support tool 2 is pushed in the arrow A direction on the floor 12 by gripping a handle 7, the wiping-out surface 3 of a cleaning material 1 collects and catches dirty things such as dust and dirt on the floor 12. When force is applied at that time, the arrow A directional end part 10 side is strongly pressed on the floor 12, so that the part being in contact with the floor 12 moves to the central part 9 side from the end part 10 as the force is reduced. The wide area of the wiping-out surface 3 is used as much as possible in this way similarly when the floor is cleaned in the arrow B direction by putting the handle 7 in a (7') attitude shown by a two-dot chain line. That is, a dirty thing collection area is expanded.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool, and more particularly to a cleaning tool with an improved shape of a cleaning tool body (support) to which a cleaning material such as a nonwoven fabric is attached.

[0002]

2. Description of the Related Art Since a conventional support has a flat bottom surface, when a nonwoven fabric is mounted thereon, only the peripheral edges at both ends in the cleaning direction where the nonwoven fabric is bent work to adsorb dust, but most of the area thereof is large. However, there is a disadvantage that dust is hardly adsorbed on the flat portion occupying the area.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to increase the dirt collecting area by increasing the dirt collecting area.

[0004]

According to the present invention, there is provided a cleaning tool for mounting a cleaning material on a bottom surface of a support which is a cleaning tool body and collecting dirt with the cleaning material. The cleaning tool is characterized in that the cleaning tool is formed in a curvature portion that has a convex central portion and forms a gentle arc toward both ends in the cleaning direction.

[0005]

FIG. 1 shows an example of a cleaning tool according to the present invention.
, A cleaning material 1 made of an electret olefin-based ultrafine fiber non-woven fabric is wound around the surface of a support 2 which is a cleaning tool main body, and is fixed to a support upper surface 4 opposite to the wiping surface 3 with a fixing tool 5 such as a screw. ing. Upper surface 4 of support 2
, A handle 7 is attached via a joint 6 that rotatably supports the support 2. Support 2
Has a central portion 9 smoothly protruding downward, is continuous therefrom, and has an end portion 10 in the cleaning direction A and an end portion 1 in the cleaning direction B.
A curved portion 8 is formed which forms a gentle convex arc toward 1. The bottom surface of the support 2, that is, the wiping surface 3 (lower surface) of the cleaning material 1 made of non-woven fabric attached to the curvature portion 8 is also convex at the center and curved toward the opposite ends in the cleaning direction by forming a gentle arc. Become.

When the handle 7 is grasped and the support 2 is pushed on the floor 12 in the direction of arrow A, the wiping surface 3 of the cleaning material 1 collects dust and dirt on the floor 12. At that time, when a force is applied, the end 10 in the direction of arrow A is strongly pressed onto the floor 12, and as the force is reduced, the portion in contact with the floor 12 moves from the end 10 toward the center. The same is true when the handle 7 is set to the position 7 'shown by the two-dot chain line and the cleaning is performed in the direction of arrow B. In this manner, as much area as possible of the wiping surface 3 is used. The area is widened, and the dirt collection efficiency is improved.

The olefinic ultrafine fiber nonwoven fabric suitable for use as the cleaning material 1 of the present invention is generally a meltblown nonwoven fabric obtained by a meltblown method. Melt blown nonwoven fabric extrudes molten resin into a fine resin stream, and this resin stream is brought into contact with a high-speed heated gas to form discontinuous fibers having a fine fiber diameter, and the fibers are accumulated on a porous support. It is obtained by this. The nonwoven fabric obtained by this method is a nonwoven fabric made of ultrafine fibers, and has a feature of being excellent in flexibility.

[0008] As the olefin resin, ethylene, propylene, 1-butene, 1-pentene, 1-hexene,
Copolymers consisting of α-olefins such as 4-methyl-1-pentene, 1-octene, 1-decene alone or a mixture thereof can be used. The olefin resin may contain a polar group-containing monomer such as an ethylenically unsaturated carboxylic acid such as acrylic acid, methacrylic acid, or an ester thereof, or a monomer containing a polar group such as an ester thereof. The monomer is useful for increasing the relative permittivity (ε) of the electret and improving the charge density. Suitable examples of the olefin resin include polyethylene, polypropylene, polybutene-1, ethylene-acrylic copolymer,
Or a blend thereof. The basis weight of the nonwoven fabric is
Although not particularly limited, generally 300 to 10 g / m ² ,
In particular, it is preferably in the range of 20 to 100 g / m ² , the fiber diameter is 0.1 μm, and the fiber length is 50 to 20 on average.
It is preferably in the range of 0 mm.

In the present invention, it is preferable to use an electret olefin type ultrafine fiber nonwoven fabric as the fibrous sheet for the following reasons. Electret is a permanent charged body where both positive and negative charges coexist. Since the external electric field is small, it does not separate the dust from a distance. It has a remarkable advantage. When this electret is formed of an olefin-based resin, charge retention is particularly good. Electretization of the olefin-based ultrafine fiber nonwoven fabric can be performed by various conventionally known methods, for example, a heat electret method, an electroelectret method, a photoelectret method, a radio electret method, a mechano-electret method, and the like. Generally, the electric field strength is preferably in the range of 20 to 100 v / cm, and the voltage imprint time is about 0.5 to 2.0 seconds. The obtained electret nonwoven fabric is generally 1 × 10 ⁹ c / cm ² or more, particularly 5 × 10 ⁹ c / cm ² or more.
It is preferable to have a surface charge density of cm ² or more from the viewpoint of dust control.

[0010]

According to the cleaning tool of the present invention, the dirt collecting area can be widened and the dirt collecting efficiency can be improved.
Also, unlike the conventional cleaning tool made of cotton fiber or the like, there is no need to repeat the rental and regeneration processes, and the device can be used easily.
