Description

Technical Field

[0001] This utility model relates to the field of massage technology, and in particular to a lower limb massager and a massage chair. Background Technology

[0002] Massage chairs are common massage devices, typically featuring lower limb massagers on the front of the seat. Traditional massage chairs have fixed support frames and footrests for the lower limb massagers, limiting their functionality. To enrich the functionality of lower limb massagers and meet the needs of more users, existing technology has developed lower limb massagers with foot stretching functions. These massagers connect the footrest to the support frame in a way that allows it to rotate vertically, and use an electric drive mechanism composed of electric push rods and linkages to drive the rotation of the footrest. However, this electric drive mechanism is relatively complex and expensive. Utility Model Content
