Detailed ways

An embodiment of the electric hair curling device of the present invention is shown in FIGS. 1 to 5 and is designated by reference numeral 10 . The device 10 includes an elongate body 12 having a first longitudinal end 14 and a second longitudinal end 16 opposite each other. Adjacent to the first longitudinal end 14 of the body 12 is an air inlet 18 through which air can enter the interior of the body 12 from the external environment. A substantially dome-shaped metal head 20 is removably engaged with the second longitudinal end 16 of the main body 12 . The head 20 is rotatable relative to the body 12 about a central longitudinal axis L-L of the head 20, as will be described in more detail below.

The main body 12 is provided with a manually operated ON/OFF switch 21 for turning on or off the device 10 and a manually operated LEFT/RIGHT button 23 for controlling the rotation direction of the head 20 relative to the main body 12 .

As shown in Figures 6 and 7, the device 10 incorporates an electric motor 22 within its body 12 to perform two functions. First, the motor 22 is coupled to a fan (not shown) inside the main body 12 to generate air flow. Downstream of the fan is a heating wire (not shown) to heat the passing air. Based on the operation of the fan, air enters the interior of the main body 12 from the external environment through the air inlet 18 . Such air then passes through the heating wire inside the body 12 and then into the inner cavity of the head 20 . The ON/OFF switch 21 is also operable to control the temperature at which the heating wire is heated, thereby controlling the temperature of the air exhausted from the device 10 .

The head 20 is detachably engaged with the main body 12 through a coupling ring 24 to move synchronously. Motor 22 is also connected to coupling ring 24 (eg, via a gear train) and thus to head 20 to drive rotation of head 20 relative to body 12 about a common central longitudinal axis L-L of head 20 and body 12 . The coupling between the motor 22 and the head 20 is such that the head 20 can be rotated relative to the body 12 about the axis L-L in a clockwise or counterclockwise direction, controlled by operating the LEFT/RIGHT button 23 . Of course, two electric motors could also be provided, one for driving the fan and the other for driving the head 20 .

The head 20 has a wide open end 26 and a narrow open end 28 , the wide open end 26 of the head 20 is fixedly engaged with the coupling ring 24 , and the coupling ring 24 is detachably engaged with the main body 12 . In operation, the motor 22 rotates the coupling ring 24 causing a corresponding rotational movement of the head 20 . The head 20 has a plurality of through holes 30 communicating with the inner cavity of the head 20 . With this arrangement, air within the interior cavity of the head 20 is forced by the fan through the perforations 30 and the narrower open end 28 of the head 20 to exit the head 20 (and thus the device 10). Understandably, the narrower open end 28 of the head 20 is larger than each aperture 30 .

The gear frame 32 is fixedly mounted on the outer surface 33 of the head 20 for synchronous movement. The toothed frame 32 has an annular portion 34 with four substantially helical tooth rows 36 . Each tooth row 36 has a base rib 38 extending helically outwardly from the annular portion 34, on which a plurality of teeth 40 are formed. Thus, when the tooth frame 32 is fixedly mounted on the head 20 , each row of teeth 36 lies in a substantially helical manner on the dome-shaped outer surface of the head 20 . A tooth 40 extends from each base rib 38 away from the outer surface 33 of the head 20 . The free end 42 of each tooth 40 is spherical. The gear frame 32 is a whole, that is, the ring portion 34 , the gear row 36 and all the gears 40 are integrally formed.

Referring now to FIG. 8, it can be seen that the angle between the central longitudinal axis L-L of the head 20 and the individual teeth 40 of each tooth row 36 varies. In particular, as shown in FIG. 8, the angle at which the tooth 40 is closest to the annular portion 34 of the tooth frame 32 (and thus farthest from the longitudinal end 16 of the body 12 when the head 20 is engaged with the body 12) is The smallest and progressively increasing relative angles are greatest when the tooth 40 is furthest from the annular portion 34 of the tooth frame 32 (and thus closest to the longitudinal end 16 of the body 12 when the head 20 is engaged with the body 12). This is the case when angles are measured in 2D (such as 2D projection) or 3D. FIG. 8 shows the angular measurement of each tooth 40 relative to the central longitudinal axis L-L of the head 20 in two dimensions.

In general, during operation of the device 10, as shown in FIG. 9, the head 20 is rotated relative to the body 12 while the device 10 is moved through the hair in a direction away from the head of the person whose hair is being treated so that the hair to create a curl effect. It should be noted that although the teeth 40 of the rows 36 are shown here as being of equal length, the lengths of the teeth 40 for each row 36 may also be arranged from the tooth 40 closest to the annular portion 34 to the furthest. The teeth 40 of the annular portion 34 increase progressively and vice versa.

10 and 11, it can be seen that each row of teeth 36a, 36b, 36c and 36d is curved approximately 90 degrees on the outer surface 33 of the head 20 when viewed from the top. Taking the tooth row 36a as an example, the topmost tooth piece (for example, the tooth piece farthest from the ring portion 34 ) is located at the position B2. It can be seen that each tooth 40 of the respective tooth row 36a, 36b, 36c and 36d lies on a different longitudinal plane passing through the head 20 and containing the central longitudinal axis L-L of the head 20 . As shown in FIG. 12 , compared with the case where all the teeth 40 on the row of teeth 36 are located on the same L-L longitudinal plane passing through the head 20 and including the central longitudinal axis of the head 20, more teeth can be provided by such an arrangement. 40. The utility model provides higher density of tooth parts, so that the hair can be easily grasped to achieve the purpose of hairdressing. This also reduces the likelihood of obstructed airflow through the narrower open end 28 and perforations 30 of the head 20 .

As can be seen in FIG. 13 , air enters the interior of the body 12 of the device 10 , travels throughout the device 10 , and exits in a substantially straight path parallel to the common central longitudinal axis L-L of the body 12 and head 20 . Furthermore, since the narrower open end 28 of the head 20 is larger than each aperture 30 , more air passes through the narrower open end 28 of the head 20 than through each aperture 30 . Thus, as shown in FIGS. 14 and 15 , heated air flows from the device 10 to the hair being treated in a generally straight path parallel to the common central longitudinal axis L-L of the body 12 and head 20 . This hot air flows directly into the center of the curls, providing a more effective and long-lasting curl on the hair.

Referring to Figures 16 to 20, which illustrate the operation steps of the device 10, a strand of hair is cut out, and the head 20 of the device 10 is placed thereunder. The LEFT/RIGHT button 23 is operated to select the direction in which the head 20 rotates relative to the main body 12 . During the rotation of the head 20, the lock of hair is locked into a curl by such rotation, while the device 10 is continuously moved away from the root of the lock of hair, so that through the rotation of the toothed member 40 of the head 20 and the inflow hair With the aid of hot air in the center of the curl, the strand of hair will be continuously curled. After being treated by the device 10, as shown in Figures 19 and 20, the curled strand is left to cool for about two minutes before being released. The user can adjust (a) the amount of curls selected, (b) the degree to which the curls are stretched, (c) the temperature of the hot air directly into the treated hair, and (d) the time the curls are released , to customize the curl effect.

As shown in FIG. 21 , the user may insert the head 20 of the device 10 deeper into the lock of hair, allow the hot air to exit the device 10 for a longer period of time and blow towards the roots, and slowly pull the device 10 through. And leave that strand of hair to "volume" the hair.

The device 10 may form part of hairstyling equipment comprising a main body 12 and a plurality of accessories (one of which is a head 20 with a toothed frame 32 ) removably engageable with the main body 12 . For example, FIG. 22 shows a brush member 44 as another accessory that is detachably engaged with the main body 12 for rotation relative to the main body 12 . Such setting provides more usage functions and provides convenience for users.

It should be noted that the head 20 may form part of any manual or motorized rotating comb.

Understandably, the above only illustrates one implementation of the present utility model, and various possible modifications and/or changes all fall within the present utility model. It will also be understood that, for the sake of brevity, various features of the invention described in a single embodiment may be provided separately or in any suitable combination.
