Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, cleaning with a brush using air is performed by sweeping dust etc. (hereinafter referred to as "dust") on the surface to be cleaned with the brush (tufted material) and then blowing or sucking the dust with air (hereinafter also referred to as "air treatment"). In this regard, in order to perform such cleaning efficiently, it can be said that it is preferable to sweep the dust at a location where the suction force or ejection force of the air is large.

[0006] However, in the horizontally wound channel brush described in Patent Document 1, the bristles are arranged in a cylindrical shape when attached to the air outlet, so the cleaning of the surface to be cleaned is mainly performed by sweeping up the debris and then treating it with air. In other words, the brush in Patent Document 1 cannot be said to sweep up debris in areas where the air suction or jet force is strong, so there was still room for improvement from the viewpoint of efficiently cleaning the surface to be cleaned.

[Modes for carrying out the invention]

[0011] The matters shown here are exemplary and for the purpose of exemplarily explaining the embodiments of the present invention, and are described for the purpose of providing an explanation that is considered to be most effective and easy to understand the principles and conceptual features of the present invention. In this regard, it is not intended to show the structural details of the present invention more than necessary for a fundamental understanding of the present invention, and it is to clarify to those skilled in the art how some forms of the present invention are actually implemented by the description combined with the drawings.

[0012] <Embodiment 1> Hereinafter, the brush 1 according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 5. In the following description, the upward direction in the state of viewing the drawings from the front side is defined as "up", and the downward direction is defined as "down".

[0013] As shown in FIG. 1, the brush 1 according to the present embodiment includes a base body 10 and a tufting base 50. Such a base body 10 and a tufting base 50 can be manufactured by, for example, additive manufacturing or molding. The materials used for the base body 10 and the tufting base 50 are not particularly limited, and for example, they may be made of metal, but from the viewpoint of weight reduction, it is preferably made of resin.

[0014] The base body 10 is a member for attaching to equipment. As shown in FIGS. 1 and 2, the base body 10 according to the present embodiment includes a base body main body 20, an equipment connection cylinder 30, and an equipment attachment piece 40.

[0015] The base body main body 20 has a first base body 21 and a second base body 26. Although it will be described in detail later, the first base body 21 and the second base body 26 are detachable from each other, and in the assembled state, they form a cylindrical shape having a flow path F through which air can flow inside.

[0016] As shown in FIGS. 1 to 3, the first base body 21 has a cylindrical shape and includes a first opening 21A formed at the upper end, a second opening 21B formed at the lower end, and an annular groove portion 22. The internal space of the first base body 21 forms a part of the flow path F and is formed in a frustum shape with a hollow cross-section that gradually increases in diameter from the first opening 21A toward the second opening 21B. The annular groove portion 22 is formed at the lower end of the first base body 21 (see FIG. 3) and can be fitted with an annular protrusion 27 of a second base body 26 described later.

[0017] As shown in FIGS. 1, 2 and 4, the second base body 26 has a cylindrical shape and includes a first opening 26A formed at the upper end, a second opening 26B formed at the lower end, and an annular protrusion 27. The internal space of the second base body 26 forms a part of the flow path F and is formed in a frustum shape with a hollow cross-section that gradually increases in diameter from the first opening 26A toward the second opening 26B. The diameter of the first opening 26A is formed to be substantially the same as the diameter of the second opening 21B of the first base body 21. The inclination gradient of the inner peripheral surface of the second base body 26 with respect to the axis A (see FIG. 2) of the base body 10 is set to be substantially the same as the inclination gradient of the inner peripheral surface of the first base body 21. The annular protrusion 27 is formed at the upper end of the second base body 26 (see FIGS. 2 and 4) and can be fitted with the annular groove portion 22 of the first base body 21.

[0018] The first base body 21 and the second base body 26 configured as described above can be assembled by fitting the annular groove portion 22 and the annular protrusion 27. In this state, the inner peripheral surfaces of the first base body 21 and the second base body 26 form a continuous surface and are configured to form a frustum shape with a hollow cross-section that gradually increases in diameter from the first opening 21A of the first base body 21 toward the second opening 26B of the second base body 26.

[0019] As shown in FIGS. 1 and 2, the equipment connection cylinder 30 is a portion that is inserted or externally inserted into the air outlet / inlet of the equipment (e.g., "nozzle"). In the following, for the sake of convenience of explanation, it is assumed that the equipment connection cylinder 30 is a portion that is externally inserted into the air outlet / inlet of the equipment (the air outlet / inlet of the equipment is inserted into the equipment connection cylinder 30) and the explanation will be made based on this premise.

[0020] The equipment connection tube 30 is cylindrical in shape and has a tip opening 30A. The tip opening 30A is formed at the upper end of the equipment connection tube 30 and functions as a mounting port that is externally fitted to the air outlet of the equipment. The inner diameter of the equipment connection tube 30 is formed to be approximately the same size as the diameter of the first opening 21A of the first base body 21. That is, it has a circular hole of the same diameter extending from the tip opening 30A to the first opening 21A. The equipment connection tube 30 is provided so as to protrude from the upper end of the first base body 21 and constitutes a part of the flow path F.

[0021] The equipment mounting piece 40 is a part used to maintain the mounting state of the base 10 attached to the air outlet of the equipment. The equipment mounting piece 40 according to this embodiment is plate-shaped and has a hole 40A. The equipment mounting piece 40 protrudes from the upper end of the first base 21 and is arranged in pairs on both sides of the equipment connecting cylinder 30.

[0022] The base 10 configured in this way can be attached to equipment by, for example, inserting the equipment connection cylinder 30 onto the air outlet of the equipment, then inserting a fastener such as a rubber band through the hole 40A of the equipment mounting piece 40, and securing it to the equipment. In this embodiment, a pair of equipment mounting pieces 40, 40 are shown as parts used to maintain the attachment state to the equipment, but these can be appropriately changed depending on the shape of the air outlet of the equipment. Examples of such changes include omitting the hole 40A and forming the outer shape of the equipment mounting piece 40 into a hook shape, or using one or three or more equipment mounting pieces 40. Also, in Figures 1 and 2, the upper end of the first base 21 is shown to be formed in a frustoconical cross-section, but similar to the equipment mounting piece 40, it can be formed into other shapes, such as a flat shape, depending on the shape of the nozzle of the equipment.

[0023] As shown in Figures 1, 2, 4, and 5, the bristles base 50 is a member for implanting the bristles B1 and has a ring-shaped form with a circular opening 50A. The bristles base 50 is formed to have an outer diameter approximately the same as the outer diameter of the second base 26 and is connected to the lower end of the second base 26. In this embodiment, the bristles base 50 is integrally molded with the second base 26 (see Figure 2).

[0024] The bristling base 50 has multiple bristling holes 51 arranged in a ring-like row at predetermined intervals, into which the bristles B1 are planted (12 in this embodiment) (see Figure 3).

[0025] The bristles implantation hole 51 is a through hole that penetrates the base body 10 in the direction of axis A, and has a large-diameter hole portion 51A and a small-diameter hole portion 51B which is smaller in diameter than the large-diameter hole portion 51A (see Figure 5). The large-diameter hole portion 51A is a hole that opens on the lower end side of the bristles implantation base 50. The small-diameter hole portion 51B is a hole that opens on the upper end side of the bristles implantation base 50 and is provided continuously with the large-diameter hole portion 51A.

[0026] Specifically, the bristles implanted in this embodiment are formed with the drilling direction inclined toward the axis A on the second base 26 side of the base 10. The inclination angle θ of the center line C of the bristles implanted in

[0027] The bristles B1 are implanted using a pull-in bristling method, as shown in Figure 5, in which the bristles are pulled into the bristling base 50. Specifically, the bristles B1 are implanted into the bristling base 50 in the following steps (1) to (3). (1) First, the binding thread T is inserted from the small-diameter hole portion 51B side of the hair implantation hole 51 toward the large-diameter hole portion 51A side. (2) Next, pass the binding thread T through the base of the bundle of bristles B1 (bristle bundle) which has been folded in half and tied together so that they are all the same length. (3) Then, while pulling the binding thread T toward the small diameter hole portion 51B of the bristle implantation hole 51, the bundle of bristle material B1 (bundle of bristle material) is pulled into the bristle implantation hole 51.

[0028] Furthermore, the bristles B1 are configured to be sequentially implanted into multiple bristles 51 using a single binding thread T. Therefore, when all bristles B1 have been implanted into the bristles 51, the binding thread T is positioned on the upper end side (small diameter hole section 51B side) of the bristles base 50 so as to run between adjacent bristles 51.

[0029] The material used for the bristles B1 is not particularly limited; for example, chemical fibers (polyethylene, nylon, polypropylene, etc.), animal fibers, plant fibers, and metal fibers can be used. The length and color of the bristles B1 are also not particularly limited. For example, the bristles B1 of the same length or color may be implanted over the entire lower end area of ​​the bristles base 50, or the lower end of the bristles base 50 may be divided into two halves, and bristles B1 of different colors may be implanted in each half. In this embodiment, the bristles B1 were implanted onto the bristles base 50 using a pull-in implantation method, but other implantation methods, such as implantation using adhesive (implantation implantation), may also be used. In this case, the implantation holes 51 do not need to be through holes; they can be concave holes (non-through holes).

[0030] As described above, the brush 1 according to this embodiment is equipped with a bristle base 50 which is located on the lower end side of the base 10 (on the side of the second opening 26B of the second base 26) and has a ring-shaped opening 50A in the center that communicates with the flow path F of the base 10. By inclining the drilling direction of the bristle holes 51 toward the axis A at the lower end side of the base 10, multiple bristles B1 are arranged to converge toward the axis A. With this configuration, multiple bristles B1 can be arranged to taper towards the ends, and a space can be formed between the lower end side of the base 10 and the tip side of the bristles B1 through which air can flow. In other words, a space is formed between the upper and lower ends of the bristles B1 arranged on the bristle base 50 through which air can flow. As a result, in the brush 1 according to this embodiment, it is possible to effectively apply the suction or jetting force of air to the tip portion of the bristles B1. Therefore, according to the brush 1 of this embodiment, although it has a simple structure, it is possible to sweep in areas where the air suction force or jet force is large, thus enabling efficient cleaning of the surface to be cleaned.

[0031] Furthermore, according to the brush 1 of this embodiment, the flow path F has a shape that gradually widens in diameter from the upper end side of the base body 10 (the first opening 21A side of the first base body 21) to the lower end side (the second opening 26B side of the second base body 26). With this configuration, it is possible to smoothly circulate air within the flow path F without causing turbulence. Therefore, according to the brush 1 of this embodiment, the suction force or jet force of air can be applied more effectively to the tip portion of the bristles B1, so that the surface to be cleaned can be cleaned efficiently and reliably.

[0032] Furthermore, according to the brush 1 of this embodiment, the bristle implantation hole 51 is a through hole for pulling in the base end of the bristle material B1. With this configuration, it is possible to improve the pull-out strength of the bristle material B1 while reducing the thickness of the bristle base 50. Accordingly, according to the brush 1 of this embodiment, it is possible to prevent the bristle material B1 from falling out while making the components other than the bristle material B1 (base body 10 and bristle base 50, see Figure 2) compact.

[0033] Furthermore, in this embodiment, the brush 1 comprises a base body 10 consisting of a first base body 21 including a first opening 21A and a second base body 26 including a second opening 26B, which is detachable from the first base body 21. With this configuration, internal processing of the base body 10 (for example, cutting when forming the flow path F) can be easily performed, and as in this embodiment, when the bristles B1 are pulled into the bristle base 50 and implanted using bristle implantation, the bristle implantation work can be easily performed through the first opening 26A of the second base body 26. Therefore, the brush 1 according to this embodiment can reliably improve productivity.

[0034] Furthermore, in this embodiment, the brush 1 has multiple bristle holes 51 formed in a ring-shaped row on the bristle base 50. This configuration makes it possible to set a wide opening area for the opening 50A of the bristle base 50. As a result, a wide space for air to flow can be secured between the lower end of the base 10 (the second opening 26B side of the second base 26) and the tip of the bristle material B1. Therefore, with the brush 1 according to this embodiment, it is possible to reliably apply the suction or jet force of air to the tip of the bristle material B1, so that dirt on the surface to be cleaned can be cleaned more efficiently and reliably.

[0035] <Embodiment 2> Next, the brush 101 according to Embodiment 2 of the present invention will be described with reference to Figures 6 to 8. Note that components similar to those of the brush 1 according to Embodiment 1 will be denoted by the same reference numerals as in Embodiment 1, and their descriptions will be omitted.

[0036] As shown in Figure 6, the brush 101 according to this embodiment comprises a brush 1, a hook-and-loop fastener 60, and a long brush body 70.

[0037] As shown in Figure 7, the hook-and-loop fastener 60 is a fastener that can be attached and detached in a planar manner, and known types can be used. The hook-and-loop fastener 60 is formed in a strip shape and is attached to the outer surface of the first base 21 of the brush 1 and to the outer surfaces of the second base 26 and the bristle base 50, respectively, using adhesive, double-sided tape, etc. The hook-and-loop fasteners 60 attached to the first base 21 side and the second base 26 side are of the same male and female type (for example, female hook-and-loop fasteners).

[0038] As shown in Figure 8, the long brush body 70 is formed by sandwiching the base ends of multiple second bristle materials B2 with a long member 71.

[0039] The elongated member 71 is made of a strip-shaped member that can be bent and deformed in the longitudinal direction and has a hook-and-loop fastener 72. The strip-shaped member is not particularly limited and can be made of, for example, a fabric made of chemical fibers (polyethylene, nylon, polypropylene, etc.), animal fibers, plant fibers, metal fibers, etc. The length of the elongated member 71 in the longitudinal direction is set to be large enough to wrap around the outer surface of the base body 10 at least once.

[0040] Furthermore, the long brush body 70 may be configured by folding a single strip-shaped long member 71 in half and sandwiching the base end of the second bristle material B2 between it, or by sandwiching it between two strip-shaped long members 71. The long member 71 and the second bristle material B2 can be joined using known joining methods such as joining with adhesive or welding.

[0041] The second bristle material B2 may be formed using the same material as bristle material B1, such as chemical fibers (polyethylene, nylon, polypropylene, etc.), animal fibers, plant fibers, or metal fibers, depending on the intended use of the brush 101, or it may be formed using different materials. Furthermore, the length and color of the second bristle material B2 are not particularly limited.

[0042] Specifically, the hook-and-loop fasteners 72 are attached to the front and back surfaces of the elongated member 71, with the second wool material B2 sandwiched between them. The attachment of the hook-and-loop fasteners 72 to the elongated member 71 is not particularly limited and may be done by sewing, or by using adhesive or double-sided tape as an intermediary.

[0043] On either the front or back surface of the elongated member 71, one of the hook-and-loop fasteners 72 is of the same male-female type as the hook-and-loop fastener 60 on the base 10 side (for example, a female hook-and-loop fastener), while the other is of a type that can be attached to and detached from the hook-and-loop fastener 60 (for example, a male hook-and-loop fastener). This makes it possible to attach the elongated brush body 70 around the base 10 and the bristle base 50 by pressing the other hook-and-loop fastener 72 of the elongated member 71 against the hook-and-loop fastener 60 on the base 10 side (see Figure 6).

[0044] Furthermore, it is preferable that the length of the second bristles B2 be set such that when the hook-and-loop fastener 72 of the long member 71 is attached to the hook-and-loop fastener 60 on the first base 21 side, its tip is positioned above the tip of the bristles B1 (see Figure 6), and when it is attached to the hook-and-loop fastener 60 on the second base 26 side, its tip is positioned below the tip of the bristles B1. In other words, when the hook-and-loop fastener 72 is attached to the first base 21 side, it is preferable that the bristles B1 extends longer downward than the second bristles B2, and when the hook-and-loop fastener 72 is attached to the second base 26 side, it is preferable that the second bristles B2 extends longer downward than the bristles B1.

[0045] With this configuration, for example, when cleaning a surface to be cleaned that has a hole formed in it, by attaching the hook-and-loop fastener 72 of the long member 71 to the hook-and-loop fastener 60 on the first base body 21 side, it becomes possible to clean the opening of the hole with the bristles B1 and the periphery of the opening and the surrounding area of ​​the hole with the second bristles B2 (see Figure 6). Also, for example, when cleaning a curved protruding surface to be cleaned, by attaching the hook-and-loop fastener 72 of the long member 71 to the hook-and-loop fastener 60 on the second base body 26 side, it becomes possible to bring the bristles B1 and the second bristles B2 into contact with the curved protruding surface to be cleaned. In this case, the surface to be cleaned can be efficiently cleaned over a wide area. Of course, when cleaning a flat surface to be cleaned, it is also possible to attach the hook-and-loop fastener 72 of the long member 71 to the hook-and-loop fastener 60 on the base body 10 side so that the tips of the bristles B1 and the second bristles B2 are the same length. In this case as well, it becomes possible to efficiently clean the surface to be cleaned over a wide area.

[0046] As described above, according to the brush 101 of this embodiment, the elongated brush body 70 can be wound around the base body 10 in the circumferential direction by attaching the hook fastener 72 of the elongated member 71 to the hook fastener 60 on the base body 10 side. With this configuration, in addition to being able to clean the debris on the surface to be cleaned with the bristles B1 on the base body 10 side as described above, it is also possible to clean it with the second bristles B2 arranged around the bristles B1. Therefore, according to the brush 101 of this embodiment, since it is possible to clean the debris on the surface to be cleaned with both the bristles B1 on the base body 10 side and the second bristles B2 on the elongated brush body 70 side as described above, the surface to be cleaned can be cleaned more efficiently.

[0047] Furthermore, in the brush 101 according to this embodiment, as described above, by appropriately adjusting the mounting position of the elongated member 71 to the base 10, it is possible to change the tip position of the second bristle material B2 to be above or below the tip position of the bristle material B1, or to change these tip positions to be at the same height. For this reason, with the brush 101 according to this embodiment, even if the surface to be cleaned has a wide variety of shapes (for example, a perforated shape, a curved shape), the tips of the bristle material B1 and the second bristle material B2 can be fitted simply by adjusting the mounting position of the elongated member 71 to the base 10, so that the surface to be cleaned can be cleaned efficiently over a wide area.

[0048] Furthermore, according to the brush 101 of this embodiment, a hook-and-loop fastener 72 is used as a member for attaching and detaching the long brush body 70 to the base body 10. Therefore, according to the brush 101 of this embodiment, the attachment and detachment of the long brush body 70 to the base body 10 can be performed very easily.

[0049] <Variation> Although embodiments of the present invention have been described above, the present invention is not limited to the above-described forms and can be implemented in various modified forms.

[0050] In the embodiments described above, air was used as the fluid flowing through the channel F, but other gases (e.g., nitrogen) or liquids (e.g., water) may also be used.

[0051] In the embodiments described above, the flow path F is formed in a hollow frustoconical shape with a gradually expanding diameter from the first opening 21A to the second opening 26B. However, it may also be formed in other shapes, such as a curved or stepped shape with a parabola in the cross-section, or in a hollow rectangular shape.

[0052] Furthermore, in the embodiments described above, the first base body 21 and the second base body 26 are configured to be joined by fitting the annular groove portion 22 of the first base body 21 and the annular projection portion 27 of the second base body 26 together, but the invention is not limited to this. For example, the annular groove portion 22 and the annular projection portion 27 of the first base body 21 and the second base body 26 may be formed in opposite directions, and other fitting methods (e.g., fitting of hook-shaped projections and protrusions), other joining methods (e.g., screw joining, tape joining), etc., can also be employed.

[0053] Furthermore, in the embodiments described above, the base body 10 is composed of two members, a first base body 21 and a second base body 26, but it may be composed of three or more members, or it may be composed of a single member (integrally molded).

[0054] Furthermore, in each of the embodiments described above, the bristles base 50 was integrally molded with the base body 10 (second base body 26) (see Figure 2), but it may also be formed as a separate part. In this case, the bristles base 50 can be joined to the base body 10 using a known joining method (for example, adhesive joining, welding joining).

[0055] Furthermore, in the embodiments described above, the bristles support 50 is provided so as to protrude radially inward from the inner circumferential surface of the base body 10 (second base body 26). However, the bristles support 50 may also be provided so as to protrude radially outward from the outer circumferential surface of the base body 10.
