Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an external view of the accessory 10 . The accessory 10 includes an air inlet 12 through which an airflow is generated at the air outlet end of a warm air cosmetic device or similar device. 2, 3 and 4, the air inlet 12 is provided by a casing including the outer casing 44, the inner casing 45 and the fixing plate 62. The air inlet 12 is generally circular, and allows a perfect connection with the generally annular outlet end of the warm air cosmetic device. From the outer surface of the warm air beauty device to the outer casing 44 of the accessory 10, the annular color division 14 forms a smooth edge.

The accessory includes at least one hair binding member when using the warm air beauty device. In this example, the accessory includes two hair engagement members. Each hair engaging member includes a movable member and a pair of cilia supported by the movable member.

In this example, both the first movable member 16 and the second movable member 18 have an elongated shape and are arranged uniformly. These movable members are positioned on both sides of the fixed shelf 22 in the longitudinal direction. The central fixed shelf 22 forms part of the inner casing 45 around which the outer casing 44 extends. The first end of each movable member is positioned at the air inlet side end of the accessory 10 , and the second end of each movable member is positioned on the upper end side of the accessory 10 .

The first movable member 16 and the second movable member 18 are positioned between the outer casing 44 and the inner casing 45 and are supported through the fixing plate 62 so as to be movable to the casing at the upper side end of the accessory. At the upper side end of the accessory, there is a cap 24 for accommodating a moving mechanism for moving the movable member in the case and a low-temperature tip 26 attached thereto.

Each movable member has a curved outer surface. On this outer surface are arranged a plurality of parallel ribs 30 extending perpendicular to the length of the movable member. Two adjacent ribs 30 form a channel 32 therebetween. The entire area of the rib 30 of each movable member has a rectangular shape surrounded by a smooth peripheral surface. Each rib 30 supports a respective row of cilia 20 .

In this embodiment, it is preferable that the width of each channel 32 is equal to or smaller than the height of the rib 30 . In other embodiments, the width of each channel 32 is greater than the width of the rib 30 . In another embodiment, the channels 32 may be multi-faceted geometries prepared by hydrodynamic analysis.

The first movable member 16 and the second movable member 18 both have an inner surface 34 adjacent the fixed shelf 22 and an outer surface 40 adjacent the sidewall 42 of the outer casing 44 . The inner face 34 of each movable member includes a series of spaced depressions 36 . The outer face 40 of each movable member includes a series of spaced depressions 38 .

Referring to FIG. 1 , the depressions at regular intervals are not in the form of the accessory 10 visible from the outside during assembly. It is preferable that the depressions 36 at regular intervals provided along the inner surface 34 have a width of about 1 mm to about 2 mm and a distance of about 10 mm to about 15 mm. It is preferable that the depressions 38 at regular intervals along the outer surface 40 have a width of about 2 mm to 3 mm and a spacing of about 2 mm to 3 mm.

A series of baffles 46 are connected to the lower surface of the fixed shelf 22 . As shown in FIG. 5 , the lateral shape of each baffle 46 is generally curved. The curvature of the series of baffles 46 gradually decreases from the air inlet side end of the accessory 10 to the upper side end of the accessory 10 . At the rear 50 of each baffle 46 , a support 52 is provided, respectively, and this support 52 is also attached to the base 53 of the inner casing 45 . It is also contemplated that the baffles 46 may be supported in other configurations, such as being placed in alignment with the longitudinal axis of the fitting 10 by contacting only a pair of parallel supports on either side of the fixed shelf 22 or each baffle 46. . In a preferred embodiment, the baffle 46 located closest to the air inlet 12 has a minimum radius of 6 mm.

Referring to FIG. 2 , a curved base 54 of the outer casing 44 extends between the outer sidewalls 42 . A side vane 56 is disposed inside each side wall 42 of the outer casing 44 . Specifically, each side vane 56 is disposed in the axial direction with the protrusion 57 of the one outer surface 40 of the movable member. Thus, the protrusion 57 of the side vane 56 is in contact so that the movable member is hermetically sealed with the outer casing 44 .

When the movable member is in this position, the channels between the abutting vanes 56 axially align with the respective depressions 38 of the outer face 40 of the movable member, thus forming a series of channels.

Referring to FIG. 2 , the part located at the upper side end of the accessory 10 mainly acts to allow a movement mechanism for moving the first movable member 16 and the second movable member 18 with respect to the casing. Specifically, the hole 60 pin 58 located at the center of the cross-section of the second end of each movable member is received. This rotation pin 58 passes through the fixing plate 62 and is received in the hole of the first side of the end cap 24 . In Fig. 2, the central axis of the inclination (inclination) of the first movable member 16 is indicated by a dotted line X. As shown in Figs. The central axis of the inclination (inclination) of the second movable member 18 is indicated by a broken line Y. As shown in FIG. Each movable member has a movement angle ranging from 5° to 30°. In a preferred embodiment, this angle of movement is 12°.

A connection object 64 protrudes from the outside of the end face of the second end of each movable member. Each connection object 64 penetrates the elliptical hole 66 of the fixing plate 62 and is received at each end of the connection arm 68 . The connecting arm 68 functions to ensure that the first movable member 16 and the second movable member 18 move synchronously to the outer casing 44 .

A pin 70 protrudes from the inside of the end face of the second end of each movable member. Each pin 70 passes through the enlarged hole 72 of the fixing plate 62 and the leg 74 of the torsion spring 76 and is ultimately coupled to each hole on the first side of the end cap 24. The torsion spring 76 is positioned between the stable first position and the stable second position and allows the first movable member 16 and the second movable member 18 to recline smoothly between the stable first position and the stable second position. do.

The second side of the cap 24 includes a cold tip 26 which is a central extension that is relatively isolated from the airflow row of the fitting.

3 is a side view of the accessory 10 showing the positions of the cross-sections indicated by lines bb and cc. FIG. 3 is a first protrusion 78 positioned adjacent to the first end of each movable member, each movable member a second protrusion 80 positioned adjacent to the second end of the . The first protrusion 78 is part of the outer casing 44 . The second protrusion 80 is part of the cap 24 . The height of the first protrusion 78 and the second protrusion 80 is preferably about 1 mm to about 4 mm.

4 : is a front view of the accessory 10 shown from the air inlet side end part 12. As shown in FIG. The connecting ring 82 has four evenly spaced protrusions 84 that form a snap-fitting mechanism to fit the accessory 10 to the warm air beauty device.

5A is a cross-sectional view taken along line d-d of FIG. 4 . The low temperature tip 26 has a plurality of elongated holes 86 to solidify the low temperature tip 26 while minimizing convection and minimizing heat conduction on the outer surface of the low temperature tip 26 .

The internal cross-sectional area of the accessory 10 gradually decreases from the air inlet side end of the accessory toward the upper side end. Specifically, the base 53 of the inner casing 45 is inclined toward the movable member from the base 54 of the outer casing 44 through the base 53, the base 54 and the inner casing 45 end plate 92 ) and forms a cavity 90 provided by the.

Figure 5b schematically shows an air inlet 12 and a plurality of air outlets indicated by vertical arrows. The trapezoid 55 represents the cross-sectional area of the internal volume of the accessory taken along the line d-d in FIG. 4 .

The cross-sectional area inside the upstream fitting is represented by the trapezoidal (55) edge (59). The cross-sectional area inside the fitting of the upper side end is indicated by the left edge portion 61 of the trapezoid 55 . The cross-sectional area of the interior volume of the accessory gradually tapers between the minimum cross-sectional area 61 of the upper side end and the maximum cross-sectional area 59 of the upstream side.

In one embodiment, the base 53 has a smooth curved shape away from the end plate 92 by slanting downward toward the sidewall 42 at a maximum height of the center of the end plate 92 . In other embodiments, the gradual tapering of the internal cross-sectional area of the fitting 10 may be realized with other configurations of the base 53 .

Hereinafter, the "alternatively elevating and lowering motion" of the movable member will be described with reference to FIGS. 6A to 6D. FIGS. 6A and 6B are lines bb and cc of FIG. 3 when the movable member is in the first configuration in the case. 6C and 6D are the same cross-sectional views as Figs. 6A and 6B, but show views when the movable member is in the case in the second configuration.

During use, a tension in the opposite direction is generated in the cilia 20 by the user's act of dragging the accessory through the hair. As a result, the tension of the cilia is present in each movable member, and each movable member has either the first configuration or the second configuration in the moving accessory 10 according to the direction of the tension.

6A and 6B show the position of each movable member in the first configuration when the accessory 10 is moved through the user's hair in the left-to-right direction as indicated by the arrow 88 in use.

The first movable member 16 on the left in FIG. 6A is in a first position with respect to the casing in which the outer division of the surface is in airtight contact with the side wall 42 face of the outer casing 44 . The inner surface 34 of the first movable member 16 is positioned below the fixed shelf 22 and vertically overlaps. A first internal air outlet 94 is formed between the fixed shelf 22 and the inner surface 34 of the first movable member 16 .

The second movable member 18 shown on the right side of FIG. 6A has a second position with respect to the casing in which the inner surface 35 is in airtight contact with the fixed shelf 22 . The second movable member 18 has an upper portion and an outer portion positioned below the sidewall 42 of the outer casing 44. The second movable member 18 and the sidewall 42 of the outer casing 44 and A second external air outlet 95 is formed between the .

It will be apparent to those skilled in the art that Fig. 6b shows a movable member in the same position as Fig. 6a. A cross section along line c-c ( FIG. 3 ) crosses the support 52 of the baffle 46 and the bottleneck 93 of the baffle 46 . The inner surface 34 of the first movable member 16 is in contact with the bottle neck 93 of the baffle 46 . The internal air outlet 94 is divided into a series of central air outlet openings by contacting the evenly spaced baffles 46 and the regularly spaced depressions 36 existing on the longitudinal side surface 34 of each movable member, Similarly, the side vanes 56 at regular intervals and the protrusions 57 at regular intervals existing on the outer surface 40 of each movable member contact each other, thereby dividing into the external air outlet openings of the external air outlets 95 .

When the direction of the user's brushing action is reversed and the direction of tension of the cilia 20 is similarly reversed, the movable member is synchronized and positioned in the opposite direction. Accordingly, the first movable member 16 and the second movable member 18 have a second configuration with respect to the casing as shown in Figs. 6C and 6D. Specifically, in use, the accessory 10 moves from right to left by arrow "89".

The first movable member 16 on the left in FIG. 6C has an inner surface 34 in contact with the fixed shelf 22 so that the outer surface 40 is located below the outer wall 42 of the outer casing 44. A third external air outlet 97 is formed between the first movable member 16 in the second position and the side wall 42 of the outer casing 44 .

The second movable member 18 shown on the right in FIG. 6C is placed in a second position where the outer surface 40 abuts the outer wall 42 of the outer casing 44 .

The inner division of the upper surface of the second movable member 18 is positioned below the fixed shelf 22 and overlaps in the vertical direction. A fourth internal air outlet 96 is formed between the second movable member 18 and the fixed shelf 22 .

It is easy for a person skilled in the art to substitute the movable member in the same position as in FIG. 6C for the second configuration in FIG. 6D. The cross-section line c-c ( FIG. 3 ) crosses the support 52 of the baffle 46 and the bottleneck 93 of the baffle 46 .

The synchronous movement between these two bottlenecks is a so-called 'seesaw' movement. This "seesaw" motion is made possible by, and limited by, the elliptical holes 72 and the holes 66 of the fixing plate 62, respectively, with the pins 58 and the connecting objects 64 positioned therein. . When the movable member has one of two different stable configurations, the accessory 10 has an open inner air outlet and a ventilated outer air outlet.

For example, when the movable member is in the first configuration, the air outlets 94 and 95 are opened and the air outlets 96 and 97 are closed. When the movable member is in the second configuration, the air outlets 94 and 95 are closed and the air outlets 96 and 97 are open.

The accessory 10 is connected to the air outlet end of the hot air beauty device when used. The airflow passes through the air inlet 12 in the hot air cosmetic device and functions to change the airflow introduced by the front face 48 of each baffle of a series of baffles 46 into the fitting. Specifically, the air flow introduced from the air inlet 12 is mainly parallel to the longitudinal axis of the accessory 10 .

The baffle 46 changes this path about 90 degrees towards the internal air outlet 94 which opens in the direction of the fixed shelf 22 . Both the front side 48 and the rear side 50 of each baffle 46 serve to change the airflow.

A series of baffles 46 cooperate with spaced depressions 36 in the inner face 34 of each movable member to form a first jet stream exiting the fitting 10 .

The side vanes 56 also open the air flow and cooperate with the spacing depressions 38 of the outer face 40 of each movable member for an external air outlet 95 to exit the second series of jets from the fitting 10 . will form an air current.

The airflow discharged from the accessory 10 through the open internal air outlet and the external air outlet is induced to flow on the outer surface of the adjacent movable member among these movable members due to the shape of the movable member.

The shape of the side vanes 56 and baffles 46 allows the jet stream to flow evenly and straight over the surface of the movable member. In an exemplary embodiment, the air flow velocity exiting each air outlet is about 30 m/s.

With the air outlet dimensions and shape of each movable member, the ambient air flow is caught in the air flow on this surface. Accordingly, the airflow along the length of the user's head through the channel 32 is increased by the ambient airflow. In addition, the shape and dimensions of the channels 32 increase the adhesion of the air stream as it travels over the surface of the movable member.

As can be seen in FIGS. 6A and 6B , when the accessory 10 is moved from left to right during use as shown by the arrow 88 at the top of the figure, the air flow on the surface of each movable member is opposite as indicated by the small arrow. to be in the direction

As can be seen with reference to FIGS. 6C and 6D , when the direction of use of the accessory 10 is reversed, the direction of air flow across the surface of each movable member is also reversed.

The cross-sectional area of the interior volume of the accessory 10 gradually decreases toward the downstream end of the accessory 10 . This cross-sectional area reduction function is to ensure a constant pressure of the air flow exiting the fittings along the length of the air outlet and to prevent turbulence. The reduction in cross-sectional area is proportional to the mass flow rate decreasing the airflow of the accessory.

The mass flow rate decreases as the air flow exits the accessory 10 from the upstream end of the accessory to the downstream end of the accessory through the internal and external air outlets.

Therefore, by reducing the cross-sectional area, the air flow velocity discharged from the accessory becomes constant according to the length of the air outlet. A gradual decrease in the internal cross-sectional area is observed resulting in improved airflow adhesion to the vanes and baffles.

The first protrusion 78 and the second protrusion 80 function to avoid undesirable entrainment of ambient air in the uniform parallel airflow moving through the channel 32 .

7a to 7d show a preferred configuration of the accessory cilia. FIG. 7A shows a row of cilia in which each cilia 99 is mounted to a home base plate 98 . Figure 7b shows the vertical section of the cilia 99, line a-a.

The proximal end 100 of the cilia 99 is wider than the ciliary tip 102 and the sides are substantially straight, and the tip 102 of the cilia 99 is generally spherical. As shown in FIG. 7C , the cross section of each ciliary tip 102 is circular. 7D shows that the cross section of the proximal end 100 of each cilia 99 is elliptical. Assembled and the long axis dimension of the elliptical shape of each cilia 20 is aligned with the long dimension (long axis dimension) of each rib 30 of each movable member.

In another embodiment, each cilia 99 has an overall elliptical cross-section, and the size of the cross-section gradually decreases toward the tip 102 of the cilia 99 .

Also, the shape of each cilia 99 can be formed to optimize the adhesion of the air stream as it travels between the cilia 20 and over the surface of each movable member. In a preferred embodiment, the length of the number at which the cilia 20 is bent (having flexibility) may be about 15 mm. The cilia 20 may or may not have a generally spherical end shape.

Those skilled in the art, as shown in Figure 7a, the hot air beauty management apparatus according to the present invention may be assembled in advance by forming two or three or more connected ciliary rows.

Each cilia 99 is disposed within a rib 30 , and optionally the rib 30 is capable of moving each cilia 99 in one or more directions. For example, allowing each cilia 99 to move slightly cushioned along the ciliary longitudinal axis may increase the comfort experienced by the user as it reduces ciliary drag to the scalp.

Referring to FIG. 1 , since the upper surface of each movable member has an arc shape, the rib 30 also draws the same arc shape.

8 shows an example of the hot air beauty device 104 to which the accessory 10 can be connected. This warm air beauty device includes a handle 106 having an air inlet 108 and an air outlet 110 on both sides. The air inlet side end of the handle forms an air inlet 108 by a row of openings extending around the handle 106 . The fan unit of the handle 106 includes a fan and a motor.

In use, air is drawn along a fluid flow path extending the entire length of the handle through a fluid inlet where the motor drives the fan. After the air is selectively heated by the heater, it is discharged from the cosmetic device using the warm air at the fluid outlet 110 .

In a further embodiment, a channel may be provided between the bases 53 and 54 to serve as a hole for thermal insulation. In a more preferred embodiment, the cavity 90, which reduces the internal cross-sectional area of the fitting, is continuous with respect to the cold wall aperture between the bases 53,54.

These cold wall apertures function to lower the temperature of the base 54 of the outer casing 44 that can contact the user.

The new structural alternative is a separate material layer covering the bottom and wall portions of the outer casing 44 of the fitting 10 in which the low-temperature walls are held at a predetermined distance from the bottom and wall portions of the outer casing 44 by minimal connecting ribs. may include

That is, when a channel is formed between the low-temperature wall and the outer casing 44, the air flow in the low-temperature wall channel can be stimulated by the venturi effect when used.

It will be apparent to those skilled in the art that the biasing function of the torsion spring 76 is provided in several different ways. For example, magnetic latches or weighted movable members or bearings integrated into the stop mechanism may be used.

The fittings may be made of any suitable heat-resistant material, and in a preferred embodiment the casing and movable member are made of glass-filled nylon. The most preferred operating temperature for these accessories connected to the hot air cosmetic device is about 130°C.

In the example of the accessory according to the present invention, two parallel movable members have been described. Alternatively, one movable member or three or four or more movable members may be used in the outer casing 44 .

In the embodiment including one movable member, the central baffle and the fixed shelf are inevitably omitted. Another embodiment involving multiple movable members includes a plurality of rows of central baffles arranged to generate a jet stream between the movable members.

In addition, in another embodiment of the accessory, it may be employed to move the movable member by a hinge motion or a sliding motion.

In the example of the accessory 10 according to the present invention, as shown in the accompanying drawings, each movable member has three rows of cilia 20 . However, it will be apparent to those skilled in the art that the number of rows of cilia for each movable member may be more or less than three.

Specifically, the hairless accessory has the advantage that the user can benefit from the hair smoothing action of the air passage rather than the unpleasant effect of the hair passing through the hair. Alternatively, instead of or in addition to arranging the cilia 20 on each movable member, the cilia 20 may be arranged on the outer casing 44 . Also, in the embodiment having multiple movable members, it is not necessary to arrange the cilia on each movable member.

The present invention is not limited to the above detailed description. Variations will be apparent to those skilled in the art.
