Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a head massager. Background Art

[0002] As we all know, scalp massage can stimulate the capillaries on the scalp, making them expand and thicken, and blood circulation is vigorous, supplying more nutrients and oxygen to the brain tissue. When the brain is well-nourished, the energy will be more abundant, and the blood circulation of the scalp is improved. In addition, there are many acupuncture points on the scalp, such as Shangxing, Baihui, Qianding, Yuzhen, etc. When massaging these acupuncture points, due to the large area of ​​massage and gentle movements, it can also promote the flow of blood and activate the meridians, playing a role in preventing and treating neurasthenia, headaches, insomnia, Alzheimer's disease, and amnesia.

[0003] For example: Chinese utility model patent CN201720703445.5 A head massager is disclosed, which has a main structure comprising a housing and four massage heads mounted on one side of the housing. The four massage heads are connected to form a rectangle, with the four massage heads being the four endpoints of the rectangle. The base of each massage head extends into the housing, and the head of each massage head extends out of the housing. A plurality of massage columns are provided on the end surface of the head of each massage head.
