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 brush for efficiently cleaning a filter, a sash, and the like.

[0002]

2. Description of the Related Art Conventional cleaning brushes have been made using the same kind of bristles. For example, bristles used for brooms and the like have been used by bundling and planting hairs that are not sharp. Although not a broom, the toothbrush disclosed in Japanese Utility Model Publication No. Sho 61-10495 alternately implants a sharp brush made of a thermoplastic polyester monofilament and a brush having no sharp portion, thereby forming a sharp brush. Is longer than a brush having no sharp portion.

[0003]

However, the prior art has a problem. That is, in the conventional broom, since the thickness and the shape of the hairs are all the same, it is not possible to simultaneously sweep finer dust and dust and the like with the larger dust than between the hairs that are planted. In addition, brooms apply excessive force to sweep out fine dust and dust that can easily pass between the hairs, causing problems such as bending the tips to bend the tips. I was holding it.

In the toothbrush disclosed in Japanese Utility Model Publication No. Sho 61-10495, sharp brushes and brushes having no sharp portions are alternately planted to improve the feeling of use on teeth and cleanability. However, when cleaning, the sharp brushes and the sharp brushes are regularly arranged alternately, so that fine dust and the like are efficiently swept by the gaps formed between the sharp brushes and the sharp brushes. However, there was a problem similar to the conventional broom.

Further, in the conventional apparatus, when removing dust and the like adhering to a filter of an air conditioner or a screen door, brooms or brushes are pressed many times to a portion to be cleaned to remove them. Was bent and the life was short. Therefore, the present invention solves this conventional problem, and simultaneously sweeps large dust and dust and small dust and dust, and further removes dust and the like adhering to a filter or a screen door. Try to provide a brush.

[0006]

The above object of the present invention can be attained by a cleaning brush for irregularly mixing and implanting sharp-pointed bristles and hollow non-pointed bristles having end faces. . Further, the problem can also be solved by a cleaning brush in which sharply pointed bristles and solid non-pointed bristles having end faces are irregularly mixed and planted. Further, the sharp hairs and the non-sharp hairs can have the same length.

That is, the cleaning brush of the present invention is a so-called brush for cleaning a cylindrical object such as a broom, a brush, a test tube and the like which can sweep dust and dirt on a floor or the like. is there. The hairs used in these cleaning brushes are obtained by irregularly implanting hollow non-sharp hairs or solid non-sharp hairs having sharp ends and end faces.

As the material of the pointed hair, hollow non-pointed hair or solid non-pointed hair used in the present invention, in particular, synthetic resin, plant fiber or animal hair can be used. As the synthetic resin, polyester, nylon,
Examples thereof include polypropylene (PP), polyethylene terephthalate (PET), and polyvinyl chloride (PVC). As plant fibers, hemp fibers, ferns, pacins, brooms and the like can be used, and as animal hairs, hairs obtained from pigs, cows, horses and the like can be used. As the sharp hair, hollow non-sharp hair, or solid non-sharp hair of the present invention, it is particularly preferable to use what is called bristles.

As the cross-sectional shape of the pointed hair, hollow non-pointed hair or solid non-pointed hair, various shapes such as substantially circular, triangular, quadrangular, and polygonal can be used. It is preferable to use an efficient, substantially circular one.
Further, as the vertical cross-sectional shape of the sharp hair, the hollow non-sharp hair or the solid non-sharp hair, various shapes can be used.
In the case of hollow non-sharp hairs or solid non-sharp hairs, those having a rectangular shape as a whole can be used. In addition, as for the pointed hairs, those having a substantially triangular shape as a whole can be used. The brush for cleaning of the present invention can be used by appropriately combining sharp hairs, hollow non-sharp hairs, or solid non-sharp hairs having such a shape according to the intended use. Hair tips can be rounded. Further, as for the sharp hair, only the tip of which is softer than hollow non-sharp hair or solid non-sharp hair can be used.

Further, the ratio of the thickness of the pointed hair, hollow non-pointed hair or solid non-pointed hair can be 1: 0.15-6.6, preferably 1: 0.5. It is desirable to set it to 2.0. Further, the ratio of the length of the sharp hairs to the length of the non-sharp hairs can be 1: 0.7 to 1, preferably 1: 0.8 to 0.95. The specific thickness of the sharp bristles, hollow non-sharp bristles, or solid non-sharp bristles used in the cleaning brush of the present invention includes:
For sharp hair, 0.15 to 1 mm, preferably 0.2 to 0.1 mm.
It is desirable that 4 mm is 0.15 to 1 mm, preferably 0.2 to 0.4 mm for hollow non-pointed hair or solid non-pointed hair. Outside of this range, there is a problem because the cleaning efficiency is reduced.

Further, the mixing ratio of the above-mentioned sharp hair is 30 to
It can be 70%, preferably 40-60%. That is, if it is less than 30%, fine dust and dust cannot be removed, and if it exceeds 70%, there are few hollow non-pointed hairs or solid non-pointed hairs.
Since it is not possible to remove large dirt and dust, and it is not possible to remove dirt adhering to the filter or screen door, it is desirable to set the above range.

[0012]

According to the cleaning brush of the present invention in which the sharp bristles having a sharp end and the hollow non-sharp bristles having an end face are irregularly mixed and implanted, the sharp bristles are formed at the sharp end portions. Fine dust and dust can be caught, and large dust and dust can be caught by the hollow non-sharp hair having an end face. In addition, when using a cleaning brush that mixes and implants irregularly the sharp non-sharp hair and the sharp non-sharp hair having a sharp end, the sharp tip of the sharp hair catches fine dust and dust, In addition, the solid non-sharp hair allows the dust and the like adhering to the filter and the screen door to be scraped off by the waist strength and the end face of the hair. Further, when the length of the sharp bristles, the hollow non-sharp bristles or the solid non-sharp bristles of the cleaning brush is the same, large dust and dust can be more efficiently swept. When the ratio of mixing the sharp hairs is 30 to 70%, large dust and dust can be more efficiently swept.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an explanatory view of a cleaning brush according to the present invention, in which the length of the tip of the pointed hair, hollow non-pointed hair, or solid non-pointed hair is irregular. FIG. 2 is an explanatory view of the sharp bristles and hollow non-sharp bristles of the cleaning brush, FIG. 3 is an explanatory view of an example of the sharp bristles, and FIG. 4 is an explanatory view of an example of a bristle shape. FIG. 5 is an explanatory diagram of another example of hair.

As shown in FIG. 1, a cleaning brush 1 having a shape shown in FIG. 1A is composed of a handle 2, a bristle attachment portion 3 and bristles 4. It has the shape of a broom to which the non-sharp hair 6 or the solid non-sharp hair 6 is fixed. The cleaning brush 1 shown in (b) is formed by twisting a wire or the like to form a pointed hair 5 and a hollow non-pointed hair 6 or a solid non-pointed hair 6.
This is an example in which is attached. In the case of (b), in order to form the handle 2 and the bristle attachment portion 3 with a wire, and further to fix the sharp hair 5 and the hollow non-sharp hair 6 or the solid non-sharp hair 6,
When the wire is twisted, it is sandwiched between the wires, and the sharp hair 5 and the hollow non-sharp hair 6 or the solid non-sharp hair 6 are attached, and the inside of a tubular material such as a test tube is cleaned. Sometimes used. The cleaning brush 1 of the form shown in (c) is composed of a handle 2, a bristle mounting portion 3, and bristles 4. The bristle mounting portion 3 causes the sharp bristles 5, the hollow non-sharp bristles 6, or the solid non-sharp bristles 6. It is in the shape of a brush to which the sharp bristles 6 are fixed. As a method of attaching the bristles 4 to the bristles attaching portion 3 of (a) or (c), the sharp bristles 5 and the hollow non-sharp bristles 6 or the solid non-sharp bristles 6 are attached to the bristle attaching portion 3 with an adhesive or the like. By fixing by means, it is fixed by inserting it into the bristle attachment part, or sandwiching it between two plates of the shape shown in the bristle attachment part 3 in the example,
Can be fixed. Alternatively, the bundle of bristles 4 can be bent at the center and implanted in the bristle attachment portion 3 of the cleaning brush. Such a cleaning brush 1 has a long brush 5
The short ones are hollow non-sharp hairs 6 or solid non-sharp hairs 6, which can be irregularly planted as shown in the figure.

FIG. 2 is an enlarged view of the state of the bristle 4 of the cleaning brush 1 shown in FIG. In the example diagram,
This is a state in which hollow non-sharp bristles 6 or solid non-sharp bristles 6 having a rectangular longitudinal cross-section and irregularly combined with the sharp bristles 5 having a sharp end portion. Thus, the cleaning brush 1 of the present invention catches small dust and dust with the sharp hairs 5 by making the sharp hairs 5 and the hollow non-sharp hairs 6 or the solid non-sharp hairs 6 irregular. Hollow non-sharp hair 6 or solid non-sharp hair 6 which is more resilient than sharp hair 5
Is to be caught and cleaned.

In FIG. 3, the pointed bristles 5 have a longitudinal cross-sectional shape shown in (a) of a substantially triangular form, and those shown in (b) have only a narrowed tip portion. This is a sharpened example. The pointed bristles 5 shown in FIG.
Is bent as a whole, it is desirable to use a material that can sweep out finer particles than dust such as powder.
Further, the sharp hair 5 shown in (b) has only the tip portion sharpened and only the tip bends, so that it can be used when sweeping dust and dust larger than (a). Further, as shown in (c), it is also possible to use a pointed hair 5 whose tip is divided into two branches. In this case, the pointed hair 5, hollow non-pointed hair 6, or solid non-pointed hair 6 is used. Since the number of pieces to be fixed to the cleaning brush 1 can be reduced, it is possible to save the trouble of manufacturing. It should be noted that, in addition to being divided into two branches in the illustrated example, it can be divided into three branches and four branches. And
Appropriate combinations of the sharp hairs having the above-described vertical cross-sectional shape can be used for the cleaning brush.

FIG. 4 shows an example of a hollow non-sharp bristles 6 having a hollow portion 7 with an open end.
(A) shows an approximately circular cross-sectional shape, (B) shows a polygonal shape, and (C) shows a general polygonal shape having different side lengths. And, in the case of the non-sharp bristles 6 of (a), since they have a general cylindrical shape, the waist is stronger than other shapes and can be used for those requiring power. In the case of (b) or (c), dust can be caught and swept away at the corners of the polygonal end face. Further, the non-sharp hair 6 may be a solid one.
If it is solid, it can be prevented from breaking. Also,
The tip can be sealed as shown in FIG. 5 in order to reduce the weight and prevent dust and dust from entering the hollow portion 7. Then, such bristles can be appropriately combined and used for a cleaning brush.

[0018]

According to the cleaning brush of the present invention, the sharp bristles and the hollow non-sharp bristles having an end face are irregularly mixed and planted, so that the sharp bristles are fine and sharp. Dust and dirt can be caught, and hollow non-sharp hairs with end faces catch large dirt and dust by the corners formed on the outer and inner circumferences of the end faces, and by once sweeping and brushing, Since dust and dust can be efficiently swept irrespective of the size, it can be prevented from being left unswept.

[0019] In addition, since the sharp hairs and the solid non-sharp hairs having an end face are irregularly mixed and implanted, fine garbage and dust can be caught at the sharp end of the sharp hairs. Further, solid non-pointed hair that is hard to break can remove dust and the like adhering to the filter and the screen door by the waist strength and end face of the hair, so that it can be kept clean. In addition, since the hair tips can be removed without bending, the life of the hair tips is extended, and the hair tips can be used for a long period of time.

Further, if the sharp hairs and the hollow non-sharp hairs or the solid non-sharp hairs have the same length, there is no step between the sharp hairs and the hairs. , And can be more efficiently cleaned, and the portion to be cleaned can be kept clean. When the mixing ratio of the sharp hairs is 30 to 70%, large and small dusts and dust can be efficiently cleaned, so that there is no remaining unswept, and the portion to be cleaned is kept clean.
