The present invention relates to a massage chair, and more particularly to a massage chair heat dissipation structure.
In order to simulate the human hands massaging a person's back, there are currently various types of massage chair technology, which allows people to experience a relaxing massage whenever and wherever possible.
As a specific example, China Patent No. CN 215229831 U provides a massage chair structure comprising a frame with a massage head, corresponding running tracks are respectively fitted to two sides of the frame on the backrest of the massage chair, and one end of the frame rolls and is supported between the two running tracks by means of running rotating shafts. A sliding track groove is provided in each of the running tracks along the length directions thereof, crankshafts are respectively configured on the other end of the frame corresponding to the running rotating shafts, and the ends of the crankshafts are respectively slide supported inside the two corresponding sides of the sliding track grooves. When the frame moves along the running track and reaches a set position, the crankshafts rotate and drive back and forth the corresponding ends of the front and rear of the frame.
Another example includes China Patent No. CN 211610659 U, which provides a seesaw type running massage mechanism, comprising a massage mechanism, a base plate, and driving wheels and driven wheels assembled on the two ends of the base plate; wherein superposed gear wheels on the wheel sides of the aforementioned driving wheels are caused to move on gear racks by a running motive power. The utility model patent is characterized in that: at least one end of the base plate is shaped to form a C-shaped opening, and the centre portion of the base plate is angled to form a raised foot end and a flat end. The above-described driving wheels are positioned on the raised foot end, and the driven wheels are positioned on the flat end. The aforementioned massage mechanism is movable positioned on the flat end through support shafts; hence, when moving back and forth one end is able to enter the C-shaped opening of the base plate, with springs helping to maintain the initial state of the massage mechanism.
The two patents described above are indeed able to provide a massage function that enables achieving a massaging effect on the human body; however, a person's back is usually tightly pressed against the back of the massage chair during massage, which easily causes the user to experience a clammy feeling.
