[0107] The following describes how to use the massage chair 100, including the following steps:

[0108] S100: The travel drive mechanism 60 drives the limb massage device 101 to travel along the length of the limb. The detection unit 70 detects the position signal of the user's limb and transmits the position signal to the controller 71. The controller 71 receives and processes the position signal and controls the travel motor 61 based on the processed position signal. The travel motor 61 drives the travel wheel 50 to move along the path setting member 80 to adjust the massage position of the limb massage device 101.

[0109] S200: The kneading drive mechanism 31 drives the kneading massage head 21 to perform a kneading massage action. The kneading motor 311 drives the kneading massage head 21 to rotate, so that the kneading massage head 21 can perform a massage action. Step S200 can be performed in addition to step S100 or can be performed independently.

[0110] At step S300, the percussion drive mechanism 32 drives the percussion massage head 22 to perform a percussion massage. The percussion motor 321 causes the swinging member 322 to swing, which in turn drives the percussion massage head 22 to move along a predetermined axis. Step S300 can be performed in addition to step S200 or independently. Step S300 can be performed in addition to step S100 or independently.

[0111] S400: When the tapping massage head 22 is at its highest point, the upper airbag 41 squeezes the upper side of the limb, and then the travel motor 61 drives the limb massage device 101 to move along the guide rail, which can provide scraping massage for the limb. The highest point of the tapping massage head 22 can be detected by the position detection unit 70. The position detection unit 70 sends the detected position signal of the tapping massage head 22 to the controller 71. The pressure sensor sends the detected pressure signal of the upper airbag 41 to the controller 71. The controller 71 controls the travel motor 61 to move according to the position signal of the tapping massage head 22 and the pressure signal of the upper airbag 41.

[0112] S400: The upper airbag 41 and / or the lower airbag 42 performs a squeezing massage on the limb. The air pump inflates or deflates the upper airbag 41 and / or the lower airbag 42 to adjust the pressure in the upper airbag 41 and / or the lower airbag 42 to perform a squeezing massage on the limb.

[0113] At step S500, after the upper and lower airbags 41 and 42 have gripped the limb, the travel motor 61 drives the limb massage device 101 along the guide rails, providing a stretching massage function. The pressure sensor detects the pressure signals from the upper and lower airbags 41 and 42 and transmits them to the controller 71. The controller 71 then controls the travel motor 61 to move based on the pressure signals, providing a stretching massage function.
