Referring to fig. 16 and 17, the outer protrusions 182 of the two heat-insulating strips 18 are embedded in the grooves 124 of the two connecting strips 125 and fixedly connected to the protection portion 12, the group of comb teeth 14 is located in the protection portion 12, each comb tooth 14 corresponds to one protection tooth 123 and is located in the annular inner portion of the protection tooth 123, the upper convex tooth 141 and the lower convex tooth 145 are located in the annular surface of the protection tooth 123, the second arc-shaped surface 1421 and the third arc-shaped surface 1461 of the comb tooth 141 are located in the gap between two adjacent protection teeth 123, and a gap 10 is formed between the edge of the upper convex tooth 141 and the edge of the lower convex tooth 145 of the comb tooth 14 and the annular protection tooth 123. In the present embodiment, the number of the comb teeth 14 is greater than or equal to the number of the guard teeth 123, and any one of the guard teeth 123 corresponds to a position of one comb tooth 14.

One comb tooth 14 near the end corresponds to the tooth surface 121 of the guard 12, and a gap 10 is formed between the edge of the upper tooth 141 and the edge of the lower tine 145 of the comb tooth 14 and the edge of the tooth surface 121; one comb tooth 141 near handle 13 corresponds to upper single tooth 1321 of upper cover 132 and lower single tooth 1361 of lower cover 136, and gaps 10 are respectively formed between the edge of upper convex tooth 14 and upper single tooth 1321 and between the edge of lower sharp tooth 145 and lower single tooth 1361.

After the assembly is completed, the two first arc surfaces 122, the second arc surfaces 1421 and the third arc surfaces 1461 form a circle 20 in a gap between the two adjacent protection teeth 123, the adjacent upper protruding teeth 141 define a first hair accommodating space on the second arc surfaces 1421, the adjacent lower pointed teeth 145 define a second hair accommodating space on the third arc surfaces 1461, the first hair accommodating space and the second hair accommodating space are distributed on the circumference of the same circle 20, when a user curls hair, the hair is simultaneously wound around the first hair accommodating space and the second hair accommodating space, that is, the hair enters through the gap between the protection parts 12 and is wound on the circle 20 formed by the two first arc surfaces 122, the second arc surfaces 1421 and the third arc surfaces 1461, and the hair is heated by the heating teeth 14 to form curls. When a user straightens hair, the hair is placed in the second hair accommodating space, namely, the hair is placed in the gap between the protection teeth 123 corresponding to the positions of the lower sharp teeth 145, when the hair is pulled relative to the electric heating comb 1, the plate-shaped lower sharp teeth 145 of the comb teeth 14 heat and straighten the hair, meanwhile, the plurality of lower sharp teeth 145 comb the hair, and due to the fact that the gaps 10 exist between the edges of the lower sharp teeth 145 and the protection teeth 123, the gaps 10 play a role in heat dissipation in the process of hot ironing and straightening the hair. When a user straightens hair, the hair can be placed in the first accommodating space, namely the hair is positioned between the adjacent upper convex teeth 141, when the hair is pulled relative to the electric heating comb 1, the upper convex teeth 141 can also heat and straighten the hair, and meanwhile, the plurality of upper convex teeth 141 play a role in combing the hair, and because the gaps 10 exist between the upper convex teeth 141 and the edges of the protection teeth 123, the gaps 10 play a role in heat dissipation in the hair blanching and straightening processes. When the comb teeth 14 are not heated, the electric heating comb 1 is directly used as a common comb, hairs are put between the protection parts 12 corresponding to the positions of the upper convex teeth 141 for combing, and the gaps 10 play a role in ventilation.

As a variation, at least a portion of the surface of the comb teeth 140, a portion of the surface of the connecting bar 125, and a portion of the surface of the insulating bar 18 form a standard cylinder for the user to curl hair.

Referring to fig. 18, at the position where the protection teeth 123 correspond to the upper convex teeth 141, the width of the left and right sides of the convex teeth 141 on the comb teeth is greater than the width of the corresponding protection teeth 123 by a distance b, where b is between 0.5 mm and 5mm, and preferably 1 mm and 2mm, and since the protection teeth 123 are made of a non-heat-conductive plastic material, when hair is located between the adjacent upper convex teeth 141, the hair can contact the heated upper convex teeth 141 due to the upper convex teeth 141 being heat-generating portions and the upper convex teeth 141 having a thickness b being added to both sides of the protection teeth 123, thereby achieving a hair curling effect.

Referring to fig. 19, at the position where the protection tooth 123 corresponds to the lower sharp tooth 145, the width of the left and right sides of the lower sharp tooth 145 of the comb teeth is greater than the width of the corresponding protection tooth 123 by a distance c, where c is between 0.5 mm and 5mm, preferably 1 mm and 2mm, and the gap between the adjacent lower sharp teeth 145 gradually decreases from the connection with the lower arc body 146 to the end thereof, so that the hair can be clamped more by a small distance between the two lower sharp teeth 145, and a squeezing effect is generated, thereby achieving a better hair waving effect. Since the protection teeth 123 are made of a non-heat conductive plastic material, when hairs are positioned between the adjacent lower tines 145, the distance c between the two sides of the protection teeth 123 is increased to allow the hairs to contact the heated lower tines 145 to achieve a hair curling effect because the lower tines 145 are heat generating parts.

In addition, the positions of the upper convex teeth 141 and the lower comb teeth 145 may be arranged in an up-and-down manner in the present embodiment, and the two are located on the same straight line, as a modification, the positions of the upper convex teeth 141 and the lower comb teeth 145 are not limited, and may be any angle therebetween, the upper convex teeth 141 and the lower comb teeth 145 are arranged on a circular arc surface formed by the first arc body 142 and the second arc body 146, and the center lines of the convex teeth 141 and the comb teeth 145 coincide. As another modification, the middle part 143 of the comb teeth 14 is a circular body having a certain thickness, the teeth 141 and the comb teeth 145 are arranged on a circular arc surface at any angle, and the thickness of the teeth 141 and the comb teeth 145 is smaller than that of the middle part 143.

As a modification, the middle portion of the comb teeth group in the electric heating comb 1 may be an integrally formed long member on which the upper and lower sets of teeth 141 and 145 extending in the first direction are provided, and the upper and lower sets of teeth 141 and 145 are positioned as described above.

Compared with the prior art, the electric heating comb provided by the invention has the advantages that the first hair accommodating space and the second hair accommodating space are arranged, so that the electric heating comb can be used for straightening hair and curling hair at the same time.

The first hair containing space and the second hair containing space are distributed on the circumference of the same circle, so that the electric heating comb can realize the hair curling function.

The lower comb teeth of the plate-shaped body are arranged on the comb teeth, so that the electric heating comb can realize the hair straightening function, and when the comb teeth are not heated, the lower comb teeth can be used as a common comb.

When a plurality of comb teeth are abutted together, the space between the adjacent upper convex teeth can be used as a part of a hair curling part, and the hair straightening function and the combing function can be realized when the hair is separately placed between the upper convex teeth, so that the electric heating comb has diversified functions.

Through setting up the broach including middleware and broach down, make directly to send out and curl the hair function and all realize through the different positions of same broach, area of contact is bigger when the broach can make the hair be located it down, and is better to the treatment effect of hair, and such broach novel structure is unique.
