Figure 2 As shown in the figure, a groove structure 11 is arranged on the circumferential outer wall of the massage head 1, the groove structure 11 includes a spiral groove 112 and an annular groove 111 away from one end of the massage part 12, one end of the spiral groove 112 is closed, and the other end is communicated with the annular groove 111, and a cylindrical guide protrusion 22 is arranged on the hole wall of the mounting inner hole 21. Figure 7 As shown in the figure, the guide protrusion 22 can slide relative to the spiral groove 112 and the annular groove 111.

[0031] As shown in the figure, Figure 2 and Figure 3 the massage head 1 is further connected with a driving assembly 3 for driving rotation of the massage head 1, when the driving assembly 3 drives the massage head 1 to rotate in the forward direction, the massage head 1 can be forced to rise under the guidance of the spiral groove 112 and the guide protrusion 22, and after the massage head 1 rises to the highest position, the massage head 1 is forced to continuously rotate under the constraint of the annular groove 111 and the guide protrusion 22, so as to realize rotary massage, and the mechanical massage mode has simple structure, good comfort and sufficient force.

[0032] When the driving assembly 3 drives the massage head 1 to rotate in the reverse direction, the massage head 1 can be forced to retract downward into the shell 2 under the guidance of the spiral groove 112, the shell 2 and the driving assembly 3 are both assembled on a base body 6, and when the massage head 1 is not used, the foam can make the surface of the seat flat, so as to avoid that the integration of the massage mechanism on the seat causes the structure of the whole seat to be bloated and causes a sense of suffocation.

[0033] As shown in the figure, Figure 4 the driving assembly 3 includes a transmission gear 31 fixed to the bottom of the massage head 1 and a motor 32 mounted on the base body 6, and the motor 32 is power-connected with the transmission gear 31 through a speed reduction device 33. Figure 5 As shown in the figure, the transmission gear 31 has an axis 34 extending upward along the axial direction, the massage head 1 has a central inner hole sleeved on the axis 34, a guide sliding groove 341 is arranged on the side of the axis, and a protrusion structure is arranged on the side wall of the central inner hole and matched with the guide sliding groove 341, so that the massage head 1 and the axis 34 can relatively slide during synchronous rotation.

[0034] As shown in the figure, Figure 6As shown, the shell 2 side wall extends outwardly with an annular mounting column 23, the annular mounting column 23 is internally provided with a cylindrical guide pin 4, the part of the guide pin 4 beyond the inner wall of the shell 2 is a guide protrusion 22. In this embodiment, the direction of the massage head 1 rising is "up", and the direction of the massage head 1 descending is "down". The gap between the guide pin 4 and the annular mounting column 23 is provided with an elastic element spring sheet 5, the side of the annular mounting column 23 is provided with a first clamping groove 231, the middle of the guide pin 4 is provided with a second clamping groove 41, the both ends of the spring sheet 5 are respectively clamped in the first clamping groove 231 and the second clamping groove 41, and the middle segment is located in the gap between the guide pin 4 and the annular mounting column 23, so that the spring sheet 5 can make the guide protrusion 22 slightly float up and down,

[0035] As shown in the figure, Figure 3 The connecting part of the spiral groove 112 and the annular groove 111 is widened to form a buffer groove 113, and the buffer groove 113 includes a buffer plane A connecting the spiral groove 112 and the annular groove 111, as shown in the figure, Figure 6 As shown in the figure, the other end of the spring sheet 5 is bent downwardly and clamped in the second clamping groove 41, so as to provide an upward force for the guide protrusion 22, when the massage head 1 rotates forwardly, the guide protrusion 22 cooperates with the upper surface of the annular groove 111 and slides relative to the annular groove 111, when passing through the buffer groove 113, under the guidance of the buffer plane A, the massage head 1 will not be interfered by the spiral groove 112, and smoothly enters the annular groove 111 and continuously rotates to perform massage. When the massage head 1 reversely rotates, the guide protrusion 22 transits from the annular groove 111 to the spiral groove 112, and is located in the buffer groove 113, at this time, the surface cover on the seat provides a downward force for the massage head 1, and at the same time, the spring sheet 5 at the end of the guide pin 4 can provide an upward force for the guide protrusion 22, so as to ensure that the guide protrusion 22 smoothly enters the spiral groove 112 and is retracted.

[0036] In this embodiment, the forward rotation and the reverse rotation of the massage head 1 are a pair of relative concepts, when the forward rotation represents the clockwise rotation, the reverse rotation represents the counterclockwise rotation, and when the forward rotation represents the counterclockwise rotation, the reverse rotation represents the clockwise rotation. Therefore, no matter whether the forward rotation (the rising process) of the massage head 1 is the clockwise rotation or the counterclockwise rotation, it shall fall within the protection scope of the present application.

[0037] Finally, it needs to be explained that the above description is only the preferred embodiment of the present application, and the ordinary skilled in the art can make various similar expressions under the inspiration of the present application without violating the purpose and the claims of the present application, and such changes fall within the protection scope of the present application.
