Description

The present invention comprises a plate having a swingable long handle attached to the center of the upper part and a square base having a cushioning material attached to the lower part of the plate and having a flat lower surface and a flat surface, and is commercially available. The present invention relates to a mop head of a flooring mop used by mounting the lower surface of the base on a cleaning sheet so as to be rolled up from the long side.

In the conventional mop head, dust is mainly collected and held in the vicinity of the end face of the lower surface of the base, so when the amount of dust collected increases, the collected dust protrudes outward from the end face of the base and is collected and held outside. The cleaning work is inefficient because it is easily peeled off in contact with the surface, and a large amount of it is peeled off depending on the condition of the external contact surface (for example, there is roughness).

In Document 1 below, the electretized non-woven fabric used as a cleaning sheet has a strong electrostatic force in the peripheral part, so the edge of the base (support) to which the sheet is attached so that the cleaning surface can uniformly adsorb and hold dust. Cleaning tools with inclined or curved parts are listed.

Further, in Document 2 below, a non-woven fabric sheet is attached to a base body having a curved lower surface having a stepped portion, and dirt is scraped off in contact with each stepped portion and dispersed. Cleaning tools are posted to the effect that dirt collection efficiency can be improved because they are performed in W1, W2, and W3, but according to this method, the scraping point W1 of the stepped portion 21 of the side portions 18A and 18B. Since it is estimated that most of the dust will be collected in, the effect of the scraping points W2 and W3 is small, and if the dirt collected by scraping in W1 increases, it will be on the outside of the sides 18A and 18B. It is considered that the base body 18 is held in a protruding state and is peeled off by touching the outside, and the superiority to the conventional cleaning tool in which the base body 18 is simply flat cannot be inferred.

In a conventional mop head, a large amount of dust is efficiently collected and at the wall by preventing the problem that the dust accumulated and held by protruding outward from the end face of the base comes into contact with the wall or figurine on the floor and peels off from the base. It provides a mop head for flooring that can collect dust on the floor at the corners as well as a conventional mop head.

The invention of claim 1 comprises a plate having a swingable long handle attached to the center of the upper part, and a base having a cushioning material attached to the lower part of the plate and having a flat lower surface and a flat surface. A square mop head that wipes and collects dust on the floor with a cleaning sheet that wraps around the bottom of the base from the side, and the width in the long side direction is 50% to 80% of the long side of the base. %, Depth of a certain dimension inward from the end face of the long side of the base, and a recess having a depth of a certain dimension from the lower surface of the base, except for each end (ear) of the long side of the base, two sides of the long side of the base. It is a mop head having a base formed near the center of each end edge of the above.

-The cleaning sheet is a non-woven fabric sheet that is usually commercially available and is attached by being wrapped around a mop head for flooring or the like and wiped on the floor to collect the attached dust.
-The long handle is a handle made of aluminum alloy or plastic that is swingably attached to the center of the upper part of the mop head with a joint or the like and has a length of a little over 1 m and is gripped and operated by the user.
-The plate forms the skeleton of the mop head body, is square and has a long handle at the top, and serves as a frame for attaching the base to the bottom. It is mainly made of plastic and has a long side of 200 to 300 mm and a short side. Is preferably 80 to 100 mm .
-The base is made of materials such as urethane foam, polyethylene foam, silicon rubber, rubber sponge, etc., and is attached to the lower part of the plate. It is flat and flat, and since it wipes dust on the floor surface through a cleaning sheet during cleaning, it has a cushioning material so that it can be reliably contacted with the floor and does not damage the floor or walls.
-The edge part means the part near the end face.

The present invention is a mop that collects (wipe off) dust on the floor by mounting a commercially available cleaning sheet on a square base having a flat and flat lower surface so as to wrap it around, and has a recess in the edge of the base. By providing, the wiping part at the lower part of the base end face that collects dust in the concave portion moves to the inside of the base and becomes the wiping part at the lower part of the concave end face, and the dust that jumps out from the concave end face and is collected and held is the base end face. Because it is guarded by the wall, it is less likely to come off by touching the wall or figurine, and more dust is stable because the upper part of the dust partially contacts the inclined part of the cleaning sheet formed at the recess. In claim 1, the corners of the floor, such as near a wall, are provided by the ears at the four corners of the lower surface of the base where the recesses are not formed, and in other forms by the long sides of the other base where the recesses are not formed. Efficient cleaning work is possible because the parts are also reliably cleaned.

15 and 16 show a working state at the time of cleaning the corner portion U near the wall by the mop head of the present invention, and as shown in FIG. 15, dust remains in the corner portion U when cleaning is performed by the recess 3. However, as shown in FIG. 16, the dust on the corner U is removed by the selvage portion 9 in the embodiment of claim 1 and by the other side where the recess is not formed in the embodiment of the other embodiment . Collected without leaving.

The above description will be described again by reorganizing the main points according to the embodiment of claim 1. Conventionally, the lower surface 5 of the square base 2 having a flat lower surface and a flat lower surface is attached and used so as to be rolled up by the cleaning sheet 4. The dust collected in the flooring mop head of No. 1 is mainly accumulated and held near the edge of the base, but when the amount is large, in the conventional mop head 10 shown in FIG. 9, it jumps out from the end face 17 of the base. There is a lot of dust that is accumulated and held, and the dust easily comes off when it comes in contact with the wall in contact with the floor or furniture on the floor, and depending on the condition of the contacting surface (for example, there is roughness), a large amount of the dust comes off. There is a problem that the efficiency of the cleaning work is lowered. Therefore, as shown in the present invention, by providing the concave portion 3 at the edge portion of the base, the lower surface 5 and the concave end surface 14 form a substantially right angle similar to the wiping portion 27 of the conventional mop head. The wiping portion 19 is collected by the wiping portion 19 by forming the wiping portion 19 at the position W in the inner direction of the base and forming the space K1 partitioned by the inclined portion S formed at the portion of the recess by the cleaning sheet 4. The dust is mainly accumulated and held in the vicinity of the concave end surface 14 of the lower surface 5, but the dust 15-2 protruding outside the end surface 14 contacts a part of the inclined portion S in the space K1 and is stably held. At the same time, it is guarded by the base end surface 7 and does not touch the wall or furniture, so that it is less likely to come off and a large amount of dust can be efficiently collected. Part 9 collects dust on the floor such as near the wall without leaving any dust.

過ぎると壁際の埃の捕集能力が低下すると同時に壁に押し付けた際に変形しやすく、逆に大き過ぎると凹部３に捕集される埃の量が少なくなる等の不具合が生ずるため、市販のモ

Next, when the concave portion 3 and the ear portion 9 are supplementarily explained, as shown in the above-mentioned "means for solving the problem", the ear portion is not formed with the concave portion, so that the ear is the base for cleaning. The part can be brought into close contact with the corners near the wall without any gaps, and has the function of surely wiping the dust off the corners .

If it is too large, the ability to collect dust near the wall will be reduced and at the same time it will be easily deformed when pressed against the wall. Deformation
