[0030] refer to Figure 2 The comb teeth 12 are provided with a plurality of arranged protruding teeth 121, and a wave groove 120 with a wave-shaped direction is formed between adjacent protruding teeth 121. The wave groove 120 is conducive to increasing the contact area or heating area with the hair, and can also make the hair heat up faster and more evenly, thereby improving the straight hair and curly hair effect.

[0031] refer to Figure 2 The comb cover 11 is provided with a plurality of tooth covers 111 arranged in a row. The tooth covers 111 correspond one-to-one with the protruding teeth 121. The tooth covers 111 are covered on the circumferential surface 123 of the protruding teeth 121. Each protruding tooth 121 is covered with a tooth cover 111, which helps to prevent burns to the scalp, hands and other parts of the human body, and improves safety.

[0032] refer to Figure 3 The top of the tooth cover 111 is provided with a protrusion 112, which is in the shape of an arc or a crescent.

[0033] The thickness of the protrusion 112 is smaller than the thickness of the tooth cover 111, and the thickness T of the protrusion 112 gradually decreases away from the comb teeth 12. This makes it easier for the tooth cover 111 to insert into the hair and separate the hair, so that the hair can enter the wave groove 120 more smoothly.

[0034] In addition, the thickness of the top of the toothed cover 111 gradually decreases away from the comb teeth 12, which helps the hair to enter the wave groove 120 more smoothly.
