Japanese Patent Laid-Open No. 7-136013 JP 2007-105144 A

  In these conventional devices, the hand-winding drum or brush body for holding the bristle is formed of a synthetic resin, and the hot air blowing position is limited to the discharge port. For this reason, the position of the hair to which hot air hits is limited, and the whole hair cannot be heated uniformly. In addition, there is a problem that some hairs are difficult to curl and braze due to insufficient heating, and it is difficult to efficiently prepare the entire hair.

  The present invention has been made in view of such circumstances, and hot air is smoothly applied to the entire hair when curling the hair using a roll brush or a blow brush, or taking a hair lash, and widening the hair. It is an object of the present invention to provide a curl dryer in which hair in a range is appropriately heated so that curling and the like can be easily performed and hair can be easily arranged.

  According to the present invention, the object is to provide a cylindrical cover having one end (base) connected to a hot air outlet such as a dryer and long in the hot air outlet direction, and a bristle held on at least a part of the cover. A curl dryer in which warm air is blown out from near the base of the bristle to the outside, and has a hollow shape extending from the base connected to the blowout port toward the tip, and from the outer periphery thereof A shaft body that discharges hot air toward the inner surface of the cover; and a metal bristle holding body that is at least a part of the cover, and the bristle holding body has a through-hole that penetrates and holds the bristle from the inside. The hot air discharge port for blowing out the hot air guided from the outer periphery of the shaft body to the inner surface of the cover from between the bristle and guiding it to the hair is formed. Karl dryer characterized the door is achieved by.

  According to the present invention, the shaft body discharges the warm air from the outer periphery thereof toward the inner surface of the cover, while at least a part of the cover surrounding the shaft body is made of a metal bristle holding body, and the through hole of the bristle holding body The bristle is passed from the inside to the inside of the shaft body, and hot air that is guided toward the inner surface of the cover from the outer periphery of the shaft body is blown out from between the bristle and a hot air discharge port that leads to the hair is formed. Hot air is efficiently guided to the inner surface of the bristle holder, and the hot air efficiently hits the hair wound around the bristle holder and the cover, thereby heating the hair. Further, since the bristle holder is made of metal and warm air blown from the outer periphery of the shaft body hits the inner surface of the bristle holder, the entire bristle holder is sufficiently heated, and the hair wound around the surface is efficiently heated. For this reason, curling and wrinkling of hair can be efficiently performed.

The perspective view of the curl dryer using the roll brush which is one Example of this invention Side view of the roll brush part Similarly, a cross-sectional view taken along line III-III in FIG. Similarly, a plan view from the tip side of the roll brush Bottom view of the roll brush in FIG. Side cross-sectional view of the roll brush section Similarly, exploded perspective view of the roll brush part Side view (A), right side view (B), and plan view (C) of the shaft body Side view (A), right side view (B), and plan view (C) of the bristle connector

  The shaft body has a three-dimensional frame structure that is gradually reduced in diameter toward the tip, and a deflection plate that projects outward from the outer periphery and guides the warm air from the inside of the shaft body to the warm air outlet of the bristle holder is fixed. Desirably, if it does in this way, the warm air which flowed in from the end (base part) of a shaft body can be smoothly guide | induced to the inner surface of a bristle holding body by these deflection plates (Claim 2).

    In this case, the outer peripheral edge of all the deflecting plates is brought closer to the inner surface of the metal bristle holding body, and the inner diameter side of the deflecting plate located on the distal end side of the shaft body is closer to the inner diameter side of the deflecting plate located on the base side. By sequentially displacing the shaft body toward the central axis side, the flow of warm air from the shaft body to the outside can be made uniform and smooth in the axial direction, and the discharge of warm air can be made more uniform in the longitudinal direction of the brush. (Claim 5).

  The cover may be a cylindrical roll brush, and the roll brush includes a cylindrical metal bristle holding body in which a bristle through hole and a hot air discharge port are formed and supported by a shaft body, and a plurality of the roll brushes. A bristle coupling body connecting the bases of the bristle, and holding the coupling portion of the bristle coupling body between the inner surface of the metal bristle holding body and the shaft body, and penetrating the bristle through the through hole. (Claim 3).

  In this case, the bristle connector is a plurality of bristles arranged side by side along a straight line, and the plurality of bristle connectors each have a plurality of ribs provided in the longitudinal direction on the outer periphery of the shaft body. It can hold | maintain between the inner surfaces of a cylindrical bristle holding body (Claim 4). That is, the bristle is passed through the through-hole from the inner surface of the cylindrical bristle holding body, and the bristle coupling bodies are arranged along the circumference. In this state, the bristle coupling bodies are aligned with the ribs of the shaft body so that the shaft body is in the bristle holding body. It is possible to assemble by making it enter, and the assemblability is good.

  A plurality of hot air outlets provided in the cylindrical bristle holder may be formed along the longitudinal direction of the shaft body between the respective bristle coupling bodies and between the deflection plates (between the deflection plates separated in the longitudinal direction of the shaft body). (Claim 6). If the hot air discharge port has a shape that is long in the longitudinal direction of the shaft body, the opening area can be increased and the discharge of hot air can be made smoother. The hot air outlet may be circular. In addition, if the through-hole through which the bristle passes is larger than the diameter of the base of the bristle so that the warm air flows out from the gap between the bristle and the through-hole, the discharge position of the warm air guided to the hair is further increased. As a result, the warm air guided to the hair is made more uniform.

  The cover may be a blow brush having a bristle in a part in the circumferential direction. In this case, the cover half having an opening in which a part of the outer peripheral surface is cut out in the length direction, the through-hole that is attached to the opening of the cover half and through which the bristle passes, and the warm air guided from the shaft body are removed. And a metal bristle holding body having a semicircular cross section (rain gutter shape) formed with a hot air discharge port leading to the surface (claim 7).

  The curl dryer shown in FIG. 1 uses a roll brush. In this figure, reference numeral 10 denotes a main body of the dryer. An electric blower fan, a heater (both not shown) and the like are accommodated in a case 12 serving as a substantially cylindrical grip of the main body 10, and is provided on the outer surface. These can be turned on and off by manual operation of the provided switch 14. A lock button 16 is provided in the vicinity of the switch 14, and this lock button 16 is used when a roll brush 18 described later is attached or detached. The upper end of the case 12 is a circular opening, to which a roll brush 18 is connected, and warm air heated by a heater flows out from this opening.

  The roll brush 18 is a combination of the shaft body 20 shown in FIGS. 7 and 8, a metal bristle holding body 22, a bristle connecting body 24, and the like. The shaft body 20 is separated in the axial direction by a cylindrical connecting portion 26 that is connected to the opening of the case 12 on the base side, and a plurality of (six) leg portions 28 having a smaller diameter than the connecting portion 26. The shaft frame part 30 connected to each other is integrally formed of resin (for example, PC, polycarbonate, etc.). Accordingly, a hot air passage 32 that guides the hot air to the outside of the shaft frame 30 is formed between the legs 28.

  As shown in FIGS. 7 and 8, the shaft skeleton 30 has a three-dimensional skeleton structure in which the diameter is gradually reduced from the inner ring 36 fixed by the rib to the inside of the cylindrical portion 34 on the base side, toward the tip. is there. That is, six vertical ribs 38 extending parallel to the axial direction, an annular rib 40 that connects these vertical ribs 38 at predetermined intervals and serves as a deflection plate of the present invention, and a tip lid fixed to the tip of the vertical rib 38 Part 42. Here, the vertical rib 38 is a thin plate in the radial direction from the center of the shaft frame 30, and a hot air passage that is an opening that opens from the inside of the shaft frame 30 to the outside between the vertical rib 38 and the annular rib 40. 44 is formed.

  The width of the vertical rib 38, that is, the width in the radial direction from the center of the shaft frame 30 is narrow on the base side (inner ring 36 side) and gradually (in steps) gradually toward the distal end lid 42 side. (See FIG. 8B). The width of the outer edge of the vertical rib 38 is set so as to hold the bristle connecting body 24 held between the vertical rib 38 and the metal bristle holding body 22 from the inner side. That is, as shown in FIGS. 7 and 9, the bristle connector 24 is formed by integrally connecting the bristle 24A arranged in a row by the connecting portion 24B. The bristle connector 24 is made of a synthetic resin having moderate flexibility, such as TPE (thermoplastic elastomer). The outer edge of the vertical rib 38 is engaged with a concave groove 24C (see FIG. 9C) formed on the back surface of the connecting portion 24B opposite to the bristle 24A, and the vertical rib 38 is made of metal as shown in FIG. The connecting portion 24 </ b> B is held between the bristle holder 22.

  Here, the metal bristle holding body 22 serves as a cylindrical cover of the present invention, and a metal cylinder (preferably a metal having good thermal conductivity such as aluminum or copper) is provided along the axis. It is formed in a divided shape, and the opposed edges of the divided semi-cylindrical halves 22A and 22A are flange portions 22B bent inward (inner diameter side). In these half bodies 22A, as shown in FIGS. 2 and 7, through holes 46 through which the bristles 24A pass and hot air discharge ports 48 are appropriately opened. The through holes 46 are linearly arranged in the axial direction corresponding to the bristle 24A of the bristle connector. The hot air discharge port 48 is appropriately opened between the straight lines of the through holes 46.

  Moreover, these half-body 22A becomes cylindrical shape by mutually abutting the flange part 22B. On the other hand, as shown in FIG. 3, a pair of flange clamping ribs 46 between the longitudinal ribs 38 and facing the longitudinal ribs 38 parallel to the longitudinal ribs 38 are symmetrical in the circumferential direction. One set is integrally formed at each position. The two opposing flange clamping ribs 46 hold the overlapped flange portions 22B and 22B with the flange portions 22B provided on each half body 22A of the metal bristle holding body 22 butted.

  As shown in FIGS. 6 and 7, each half body 22 </ b> A has the bristle 24 </ b> A of the bristle connector 24 penetrating from the inside through the through hole 46 in advance, and the lower edge thereof is the cylindrical portion 34 of the shaft body skeleton portion 30. The upper groove is engaged with a concave groove formed on the upper edge, and the upper edge is engaged with and fixed to a cap 50 fixed to the distal end lid portion 42 of the shaft frame 30. That is, the flange portions 22B of the respective half bodies 22A are abutted and inserted between the flange clamping ribs 46 of the shaft frame 30. At this time, each half 22A is assembled to the shaft frame 30 while engaging the groove 24C of the connecting portion 24 of each bristle connector 24 with the vertical rib 38. The cap 50 is fixed by screwing a tapping screw 52 inserted into the center thereof into the boss portion of the tip lid portion 42 from above.

  In this embodiment, the deflection plate 40 is provided in four stages in the longitudinal direction of the shaft frame 30 as shown in FIG. Since the inner edge (edge on the center side) of the vertical rib 38 of the shaft frame 30 is gradually displaced toward the tip, the inner edge of the deflection plate 40 is gradually moved toward the center. Will grow. For this reason, the warm air that has flowed into the shaft frame 30 is sequentially applied to the deflecting plate 40 at each stage, and is guided from the warm air passage 44 of the shaft frame 30 to the outer peripheral side.

  This roll brush 18 connects the cylindrical connecting portion 26 to the hot air outlet on the main body side of the dryer, and blows out hot air by operating the switch 14. As shown by an arrow in FIG. 6, a part of the hot air flows through the hot air passage 32 to the outside of the metal bristle holder 22, and most of the remaining air is a cylindrical part 34 on the base side of the shaft frame 30. Through and into the shaft skeleton 30. The hot air that has entered the shaft frame 30 is sequentially deflected outward by the deflecting plate 40 at each stage whose inner edge extends inward in the flow direction, passes through the hot air passage 44, and the inner surface of the metal bristle holder 22. Led to. Accordingly, the amount of warm air discharged is equalized in the longitudinal direction of the roll brush 18. This warm air flows out from the warm air discharge port 48 of the metal bristle holder 22. Further, when there is a gap between the through hole 46 and the bristle 24A, the warm air also flows out from this gap.

  When the roll brush 18 is used, the body unit 10 is held to wind the hair around the roll brush 18 to curl the hair, attach a hair fold, or correct the hair lash. At this time, a part of the warm air flows from the warm air passage 32 to the outside of the metal bristle holder 22, and the remaining warm air flows from the warm air discharge port 48. For this reason, a sufficient amount of warm air is applied to the hair wound around the metal bristle holding body 22 and held by the bristle 24A, and heating of the hair is promoted.

  Further, since the metal bristle holding body 22 is made of metal, it is heated by the warm air that has entered the inner surface thereof, so that the hair wrapped around the metal bristle holding body 22 is also heated by heat transfer from the surface of the metal bristle holding body 22. Is done. Accordingly, the heating of the hair is further promoted, and the efficiency of curling the hair is improved.
