TECHNICAL FIELD

The present disclosure relates to the field of hairdressing appliances, in particular to a foldable hand-held hair care device.

BACKGROUND

Hair care devices include air combs, hair dryers, hair conditioners, scalp physiotherapy apparatus, etc. Combing is one of the indispensable daily trims to keep your hair beautiful. Combing can get rid of the peel puffing and dirt on your head and hairs, and give moderate stimulation to the scalp to promote blood circulation and make hair soft and shiny. Combs and electric hair dryers are commonly used items in daily life. Combs are mainly used for combing the hair, beard or animal fur, while the electric hair dryer is mainly used to dry the hair or beard. When users finish washing their hair, they usually need a comb and an electric hair dryer respectively to comb and dry the hair. It is relatively troublesome and inconvenient to use the comb and the electric hair dryer separately, and the comfort level is relatively low. The air comb is an improved product of the electric hair dryer. This kind of hair care appliance can not only dry the hair, but also comb and massage the hair. Depending on different hairstyles of different users, it can also replace with different blowing nozzles. Therefore, air comb has gradually become a necessary item for hairdressing.

For the existing air combs, handle and blowing nozzle are usually on the same straight line as a whole. When in use, it is necessary to constantly wave your arms to dry and comb the hair according to different needs of blowing nozzles. It is often required to raise your arms, which is very laborious and inconvenient for users and degrades their experience. And it will occupy too much space for storage, resulting in storage troubles.
