Hair straightening is generally needed at hairdressing industry, which usually utilizes a hair straightening tool. Generally, a hair straightening tool is clamp-type hair straightener, which has two clamp plates, being opposite to each other. Each clamp plate has a heating element disposed therein for straightening the hair between the two clamp plates. The problem is that the clamp-type hair straightener only can be used to straightening the hair, but can't be used to combing the hair. Therefore, an operator generally needs to hold a comb and the clamp-type straightener at the same time. So, the operation is inconvenient and inefficient.

Therefore, a new type electric straightening comb is needed, which should be safely, conveniently, and effectively for hair straightening.

Reference will now be made to the drawings to describe preferred and exemplary embodiments in details.

FIGS. 1, 2, 3 and 4, a wavy-shaped electric straightening comb of the present invention includes a comb part 2 and a handle 1, which are connected together in sequence. The comb part 2 includes a heating equipment (not labeled) and a plurality of comb teeth extending outwardly. The comb part 2 includes a first comb 3 and a second comb 4, which the first comb 3 keeps close to the heating equipment and conducts heat energy to the second comb 4. The first comb 3 includes a first fixing plate 21 and a plurality of first comb teeth 32 disposed on the first fixing plate 21 at a regularly intervals. The second comb 4 includes a second fixing plate 41, a plurality of second comb teeth 42, a plurality of through holes (not labeled), each formed between two adjacent second comb teeth 42 defined on the second fixing plate 41. The plurality of first comb teeth 32 of the first comb 3 respectively drills through the plurality of through holes of the second comb 4, each first comb tooth 32 being disposed between two corresponding adjacent second comb teeth 42. Thus the first comb 2 and the second comb 4 are assembled together. Each of the first comb teeth 32 and the second comb teeth 42 defines a wavy-shaped cross-section. Two adjacent first and second comb teeth 32, 42 keep an interval from 0.25 mm to 1.5 mm and define a wavy-shaped hair accommodating space. The comb part 2 further includes a front cover 5, disposed before the handle 1, and a heat shield 6 on the front cover 5. The heat shield 6 includes a plurality of comb-shaped sheath 61, each of which is a hollow structure, respectively corresponding to each of the first comb teeth 32 and the second comb teeth 42, and respectively surrounding an outer peripheral face of each of the first comb teeth 32 and the second comb teeth 42. The first comb 3 and the second comb 4 are used to be heated for straightening the hair, and the heat shield 6 disposed out of the first comb 3 and the second comb 4 are used to prevent scalding a scalp of a user.

The handle 1 includes a front cover 7, a rear cover 8, and a cable 9 formed at an end of the front cover 7, a PCB (printed circuit board) 10 disposed on a rear part of the front cover 7, a light shield 11 on a front part of the PCB 10, and a button module 12 on a rear part of the PCB 10. The rear cover 8 has a light guide 13, and a plurality of button holes 14, respectively corresponding to the light shield 11 and the button module 12. The front cover 7, the rear cover 8 and the cable 9 are assembled together through a cable ring 15. The PCB 10 and the button module 12 cooperate to turn on/off the wavy-shaped electric straightening comb. The light shield 11 and the light guide 13 are used to cooperate to transmit a displaying light to the rear cover 8 for indicating a temperature scope.

The heating equipment includes a holder 16 being accommodated in the handle, a heating element 17 disposed on the holder 16, two contact terminals 18 electrically connecting the heating element 17 to the PCB 10. The heating element 17 defines a heating area 19, which is attached to the first comb 3. When the heating element 17 is driven to emit heat, the heat energy is transmitted to the first comb 3 and the second comb 4 for realizing straightening the hair. In addition, the wavy-shaped electric straightening comb further has an antiskid cover 20 on the rear part of the front cover 7, and a front decoration cover 21 set on the antiskid cover 20. The rear cover 8 further provides a rear decoration cover 22, which has a plurality of openings respectively corresponding to the button hole 14 and the light guider 13.

Each of the first comb teeth 32 and the second comb teeth 42 defines a V-shaped peripheral profile and a wavy-shaped cross-section. A width of each of the first comb teeth 32 and the second comb teeth 42 gradually decreases to near-zero from its root end to its top end. In assembly, the two adjacent first and second comb teeth 32, 42 define a wavy-shaped accommodating space for accommodating the hair therein, and straightening the hair through a high-temperature heat energy. Compare to the conventional clamp-type hair straightener, the wavy-shaped electric straightening comb of the present invention defines a wavy-shaped accommodating space through the wavy shaped cross-sections of the two adjacent first and second comb teeth 32, 42, which the wavy-shaped accommodating space can provide a pulling force to the hair accommodated therein through a wave crest and a wave valley of each of the two adjacent first and second comb teeth 32, 42. Thus, when the hair passes through the accommodating space between the two adjacent first and second comb teeth 32, 42, the hair are loaded a reasonable pulling force and heated at a reasonable temperature to realize a straightening purpose. In addition, the wavy-shaped electric straightening comb can prevent the user to be scalded for a wrong operation by provide the heat shield 6, which further has two baffles 62 at two ends of the heat shield 6. Furthermore, the heat shield 6 can provide a better pass way, because it's an one-to-one correspondence between the comb-shaped sheath 61 of the heat shield 6 and the first and the second comb teeth 32, 42, and an interval between two adjacent comb-shaped sheath 61 is larger than that between the adjacent first and second comb teeth 32, 42. Moreover, the interval between the adjacent first and second comb teeth 32, 42 gradually decreases to near-zero from its top end to its root end. Thus, the hair can easily enter into the interval therebetween, and can be more effectively straightened through being loaded a clamp force between the adjacent first and second comb teeth 32,42, the pulling force between a wave crest and a wave valley of each of the adjacent first and second comb teeth 32, 42, and the heat energy from the heating element 17 conducted by the adjacent first and second comb teeth 32, 42. Furthermore, the interval between the adjacent first and second comb teeth 32, 42 is from 0.25 mm to 1.5 mm, which is specially designed for getting an better hair straightening results. A closely interval can assure an ideal strength of the clamp force and the pulling force, and a perfect cooperation of the strength and the temperature of the heat energy thereon. Finally, when the wavy-shaped electric straightening comb are assembled, the first and the second comb 3, 4 are fixed, and the first and the second comb teeth 32, 42 are immovable, and the interval between the adjacent first and second comb teeth 32, 42 is unalterable. Thus, the operation for the user is easy and convenient, and the special design of the wavy-shaped electric straightening comb can assure the straightening effects. In use, the interval between the adjacent first and second comb teeth 32, 42 can be 0.25 mm, 0.5 mm, 1.0 mm, 1.2 mm, or 1.5 mm. The producer can choose different intervals according to different user.

It is believed that the embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
