[0002] Hair care devices include air combs, hair dryers, hair care devices, scalp therapy devices, etc. Combing hair is one of the indispensable daily grooming methods for maintaining beautiful hair. Combing hair can remove the loose skin and dirt on the head and hair, and give the scalp a moderate stimulation to promote blood circulation, making the hair soft and shiny. Combs and hair dryers are both commonly used daily necessities in life. Combs are mainly used for combing hair, beards or animal hair, and hair dryers are mainly used to dry hair or beards. After washing hair, users usually need to use combs and hair dryers to comb and dry hair respectively. It is relatively troublesome and inconvenient to use combs and hair dryers separately, and the comfort is relatively low. Air combs are a modified product of hair dryers. This hair care appliance can comb and massage hair while drying hair. Different hair dryers can be replaced according to different hairstyles of different user groups. Therefore, air combs have gradually become a must-have for hairdressing.

[0003] The handle and the hair dryer of the existing hair comb are usually in the same straight line, and the whole is straight. When using it, you need to keep swinging your arms to dry and comb your hair according to different needs of blowing and hair dryer, and you often need to raise your arms, which is very laborious and inconvenient for the user, reducing the user's experience.
