It should be noted that, the rear airbag 11 may be configured to move, that is, when the rear airbag 11 inflates, the front airbag 11 moves downward due to the increase of the volume, and when the rear airbag 11 deflates, the front airbag 11 moves upward due to the decrease of the volume, so that, based on the movement of the eccentric frame 5, and in addition, the rear airbag moves up and down in the direction indicated by the arrow in fig. 1, the moving track of the whole airbag 11 is more variable, and the massage comfort is further increased. And the air bag 11 is flexibly rotated along with the eccentric frame 5 in an air blowing state and extrudes the arm part of the human body, when the soft air bag 11 extrudes the skin of the human body, the discomfort caused by hard body feeling or the larger body feeling difference caused by different thicknesses of limbs of a user when the skin is extruded by solid bodies can not be caused, but the soft and comfortable feeling can be realized, the compatibility of applicable people is higher, almost consistent body feeling can be obtained when most of body type people use the massage chair, and the comfort level of the massage chair and the applicable people are increased.
Example two
As shown in fig. 2, the basic structure of the massage chair of the present embodiment is the same as that of the first embodiment, except that a massage plate 13 is mounted above each massage wheel 4, one end of the massage plate 13 is curled to form a mounting hole (not shown) and is sleeved on the fixed shaft 6, and the bottom surface of each massage plate 13 is in contact with the corresponding massage wheel 4. When the inflatable massager works, the wavy massage wheels 4 sequentially drive the massage plates 13 to flap the human body from front to back, the eccentric frame 5 flexibly rotates by taking the fixed shaft 6 as an original point in the rotating process of the rotating shaft 3, and the air bag 11 flexibly rotates along with the eccentric frame 5 in an inflating state and extrudes the human body.
EXAMPLE III
As shown in fig. 3, the basic structure of the massage chair in this embodiment is the same as that in the first embodiment, the only difference is that a massage ball 14 is mounted at the outer circumference of each massage wheel 4, and the mounting angles of the plurality of massage balls 14 with respect to the corresponding massage wheels 4 are sequentially changed from a position close to the motor 1 to a position far from the motor 1, so that the plurality of massage balls 14 are mounted in a wavy shape as viewed from the side of the rotating shaft 3. When the massage device works, the massage wheels 4 arranged in a wavy manner sequentially drive the massage balls 14 to sequentially flap the human body from front to back, the eccentric frame 5 flexibly rotates by taking the fixed shaft 6 as an original point in the rotating process of the rotating shaft 3, and the air bag 11 flexibly rotates along with the eccentric frame 5 in an air blowing state and extrudes the human body.
The double eccentric link structures of the first to third embodiments can be applied to massage chairs.
