• the cleaning tool 10 of the present invention has a cleaning head 1 that is approximately rectangular in plan view and an operating handle 2 fixed to the top surface 1a of the cleaning head 1, and is used by attaching a cleaning sheet X (see Figure 4) made of nonwoven fabric to cover the bottom surface 1b of the cleaning head 1 using brush-shaped fixing parts 5a, 5b formed on the bottom surface 1b of the cleaning head 1 or engaging groove-shaped fixing parts 5c, 5d formed on the side of the cleaning head using a soft material.
• a cleaning sheet X made of nonwoven fabric
• the brush-shaped fixing parts 5a, 5b formed on the bottom surface 1b of the cleaning head 1 are made up of brush members made of multiple bristles, and are fixed by inserting the tips of the multiple bristles into the nonwoven fabric of the cleaning sheet X, where the multiple fibers are entangled.
• each of the multiple bristles has a protrusion at its tip that extends in the radial direction, and adjacent bristles are planted at intervals such that they interfere with each other.
• the bristles and cleaning sheet X are secured together by the protrusions of the bristles catching on the fibers of the cleaning sheet X. This allows the cleaning sheet X to be easily secured to the cleaning head 1.
• the bottom surface 1b of the cleaning head 1 has a plurality of polygonal protrusions 3, 13, 23, 33 with four or more corners 3a, 3b, 3c, 3d, and grooves 4, 14, 24, 34 formed around each of the plurality of protrusions 3, 13, 23, 33. Two or more corners of the protrusions 3, 13, 23, 33 are formed perpendicular to the longitudinal direction of the cleaning head 1. Furthermore, a plurality of triangular protrusions 43, 53 are formed on both end sides of the cleaning head 1. Furthermore, the bottom surface 1b of the cleaning head is made of a soft material, and when it is brought into contact with the surface to be cleaned via a cleaning sheet, it conforms to the uneven shape of the surface to be cleaned. This allows the cleaning sheet to be pressed firmly against the surface to be cleaned, improving cleaning effectiveness.
• the cleaning tool 10 has a cleaning head 1 with multiple polygonal protrusions on the bottom surface, each with four or more corners, and grooves formed around each of these multiple protrusions. This improves durability and reduces manufacturing costs, and allows the cleaning tool 10 to scrape off dust adhering to the surface to be cleaned while firmly holding the entire cleaning sheet. Furthermore, because two or more corners of the protrusions are formed in a direction perpendicular to the longitudinal direction of the cleaning head, when the cleaning head is moved back and forth over the surface to be cleaned, it can strongly scrape off dust adhering to the surface to be cleaned, allowing the entire surface to be cleaned.
• the cleaning tool 10 has a cleaning head 1 that also functions as a suction tool for an electric vacuum cleaner, but it can also be applied to a regular mop that does not have this function, and this is also included in the present invention.
• protrusions 3, 13, 23, 33 on the cleaning tool 10 there are more protrusions 3, 13 on the central side in the short direction of the bottom surface 1b of the cleaning head 1 than there are protrusions 23, 33 on both end sides. This allows for more corners 3a, 3b, ..., 13a, 13b, ... to be arranged on the central side in the short direction of the bottom surface 1b of the cleaning head 1, improving cleaning effectiveness.
• the grooves 4, 14 formed around adjacent protrusions 3, 13 of the cleaning tool 10 are connected to each other. This allows captured dust to be transported in a specified direction, improving cleaning effectiveness.
• the interconnected grooves 4, 14, 24, and 34 of the cleaning tool 10 are not formed in a straight line connecting one end and the other end of the short side of the bottom surface 1b of the cleaning head 1.
• the straight line extends from one or the other end of the short side of the bottom surface 1b of the cleaning head 1 to near the center. This allows captured dust to be held in the grooves 4 and 14 near the center, improving the cleaning effect. Note that the cleaning effect can also be improved if the grooves 4, 14, 24, and 34 are interconnected in a wavy or stepped pattern, and this is included in the present invention.
• the multiple protrusions 3, 13, 23, and 33 of the cleaning tool 10 have corners 3c, 3d, 13c, 13d, 23c, 23d, 33c, and 33d formed along the length of the cleaning head. This improves the dust scraping effect even when the cleaning head 1 is moved left and right.
• the longitudinal direction of grooves 4, 14, 24, and 34 is not perpendicular to the longitudinal direction of the cleaning head 1, but is formed at an angle to the perpendicular direction. This allows dust to come into contact with the sides of the grooves when the cleaning head 1 is moved back and forth, improving the retention effect.
• Figure 3(a) is a partially enlarged perspective view of a cleaning tool according to the present invention
• Figure 3(b) is a partially enlarged bottom view of the cleaning tool according to the present invention.
• the widths 4a, 14a, and 24a of the grooves of the cleaning tool 10 are narrower at the center 4a in the short direction of the bottom surface of the cleaning head 1 than at both end 24a. This allows captured dust to be concentrated toward the center, improving cleaning effectiveness.
• the reference numeral 7 in Figure 3(a) denotes a blade made of a soft material. When the cleaning tool 10 is in use, the blade 7 presses the cleaning sheet against the surface to be cleaned, improving cleaning effectiveness and preventing the cleaning sheet from slipping.
• the corners of the multiple protrusions 23 of the cleaning tool 10, which are formed in a direction perpendicular to the longitudinal direction of the cleaning head 1, include corners formed at a reflex angle ⁇ . This allows the two sides forming the reflex angle ⁇ to catch and hold dust, etc., thereby improving the dust scraping and retention effects.
• the corners formed by the minor angles ⁇ , ⁇ , and ⁇ of the multiple convex portions of the cleaning tool 10 are formed at different angles. This allows the minor angles ⁇ , ⁇ , and ⁇ to come into contact with dust adhering to the surface to be cleaned, improving the dust scraping effect.
• the multiple protrusions have corners formed at a minor angle ⁇ positioned opposite corners formed at a reflex angle ⁇ and across the groove 4. This allows dust to be securely held by the groove 4 sandwiched between the reflex angle ⁇ and the minor angle ⁇ when the cleaning head 1 is moved back and forth, further improving the dust scraping effect.
• the interconnected grooves 4, 14, and 24 of the cleaning tool 10 include two different sizes of grooves formed in a grid pattern. This allows dust particles of various sizes to be retained in stages, improving the dust scraping and retention effects and further improving the cleaning effect.
• the interconnected grooves 4, 14, 24 are formed so that the groove width gradually narrows (4a ⁇ 14a ⁇ 24a) from one end toward the center in the short direction of the bottom surface 1b of the cleaning head 1. This allows captured dust to be concentrated toward the center, and dust held in the grooves 4, 14 on the central side can be compressed and held firmly, further improving cleaning effectiveness.
• openings 6a, 6b are formed at the ends of the grooves 24, 34 on both end sides, making it easier for dust adhering to the surface to be cleaned to be captured into the grooves 24, 34.
• the bottom surface 1b of the cleaning head 1 is formed with multiple convex portions and grooves that are line-symmetrical on both end sides with the approximate center in the short direction as the boundary, improving cleaning effectiveness whether the cleaning head 1 is moved forward or backward during use.
• Fig. 4(a) is a cross-sectional view taken along line A-A in Fig. 2(a), and Fig. 4(b) is an enlarged cross-sectional view of a portion of the cleaning tool according to the present invention when in use.
• the cleaning tool 10 according to the present invention is configured to also function as a suction tool for an electric vacuum cleaner, and relatively large dust particles sucked in through the suction port 2a are transported to the vacuum cleaner body via the suction passage 2b formed in the operating handle 2.
• the bottom surfaces 4b, 24b of the grooves are configured so that the central side 4b in the short direction is closer to the surface Y to be cleaned than the end sides 24b. This allows the grooves 24 on the end sides to hold relatively large dust particles Z. Furthermore, the grooves 4 on the central side can hold small dust particles Z, making it possible to hold dust particles of various sizes in stages, further improving the cleaning effect.
• the cleaning tool of the present invention is used as a cleaning tool to remove dirt, dust, etc. from floors, walls, windows, etc. indoors.
