The upper end face of the base plate abuts against the drive shaft, and the lower end face contacts the lifting unit. The outer periphery of the base plate has guide protrusions, and the inner wall of the cavity has guide grooves. The guide protrusions cooperate with the guide grooves.

[0009] Furthermore, the bottom of the drive shaft has an inner cavity, and a connecting post is provided in the inner cavity. The cylinder has a through hole, the cylinder is inserted into the inner cavity, and the connecting post is inserted into the through hole.

[0010] Furthermore, in order to achieve rapid lifting and lowering of the massage head, the lifting unit is an airbag, which inflates and pushes the pad and drives the drive shaft to rise.

[0011] Furthermore, in order to achieve the rotation of the drive shaft, the drive assembly includes a first gear, which is connected to the drive shaft for power transmission, and the drive shaft can move up and down relative to the first gear.

[0012] Furthermore, in order to optimize the position of the transmission components, the first gear is rotatably connected to the base and is used to seal the cavity.

[0013] Furthermore, in order to achieve power transmission, the first gear meshes with the second gear, and the second gear is rotatably connected to the base.

[0014] Furthermore, in order for the motor to drive the massage head to rotate, the second gear meshes with the output shaft of the motor, which is located in the middle of the base.

[0015] Furthermore, to enhance the massage effect, the base has a symmetrical structure, and there are two drive components and two massage components arranged symmetrically.

[0028] like Figures 1 to 3 As shown, a massage device with a lifting massage head includes: a base 1, a drive assembly 2, a massage assembly 3, and a lifting unit 4. The drive assembly 2 is mounted on the base 1.

[0029] Specifically, the base 1 has a cavity 11, and the massage assembly 3 includes a drive shaft 31 that is connected to the drive assembly 2 for power transmission. The lower end of the drive shaft 31 enters the cavity 11 and approaches the bottom of the cavity 11, while the upper end extends out of the cavity 11 and connects to the massage head 32. Most of the drive shaft 31 is located inside the cavity 11, with only the upper end extending out of the cavity 11 and connecting to the massage head 32. This reduces the vertical space occupied by the massage assembly 3 and decreases the thickness of the massage device.

[0030] Specifically, the lifting unit 4 is located at the bottom of the cavity 11 and pushes the transmission shaft 31 to move it axially up and down within the cavity 11.

[0031] Preferably, the cavity 11 also includes a pad 5, with the lifting unit 4 located below the pad 5, and the lower end of the drive shaft 31 rotatably connected to the pad 5. Since the drive shaft 31 needs to drive the massage head 32 to rotate, the pad 5 is added between the drive shaft 31 and the lifting unit 4, allowing the drive shaft 31 and the pad 5 to rise and fall synchronously, and the drive shaft 31 to rotate relative to the pad 5. The inflation of the airbag pushes the pad 5 upward, which in turn drives the drive shaft 31 and the massage head 32 upward. Because there is no power transmission between the drive shaft 31 and the pad 5, the drive shaft 31 can rotate relative to the pad 5. Therefore, the massage head 32 can rotate and massage while rising and falling, improving the massage effect.

[0032] Preferably, the pad 5 includes a base plate 51 and a cylinder 52. The cylinder 52 is inserted into the drive shaft 31, and the drive shaft 31 rotates circumferentially relative to the cylinder 52. The upper end face of the base plate 51 abuts against the drive shaft 31, and the lower end face contacts the lifting unit 4. The outer periphery of the base plate 51 has a guide protrusion 511, and the inner wall of the cavity 11 has a guide groove. The guide protrusion 511 cooperates with the guide groove. The airbag and the base plate 51 are in surface-to-surface contact, and the cavity 11 guides the base plate 51, ensuring that the base plate 51 rises and falls in the vertical direction and does not rotate with the drive shaft 31, thus preventing the drive shaft 31 from tilting in the vertical direction.

[0033] Preferably, the bottom of the drive shaft 31 has an inner cavity 311, within which a connecting post 312 is provided. The cylinder 52 has a through hole, and the cylinder 52 is inserted into the inner cavity 311, with the connecting post 312 inserted into the through hole. Through the cooperation of the connecting post 312, the cylinder 52, the through hole, and the inner cavity 311, the bottom of the drive shaft 31 is positioned and guided, ensuring that the drive shaft 31 can be smoothly raised, lowered, and rotated.

[0034] Preferably, the lifting unit 4 is an airbag, which is inflated and deflated by an air pump and an air valve. After the airbag is inflated, it pushes the pad 5 and drives the drive shaft 31 to rise, causing the drive shaft 31 and the massage head 32 to rise. Similarly, when the airbag is deflated, the drive shaft 31 and the massage head 32 descend and return to their original positions.

[0035] Specifically, the drive assembly 2 includes a first gear 21, which is connected to the drive shaft 31 for power transmission, and the drive shaft 31 can move up and down relative to the first gear 21. Preferably, the drive shaft 31 passes through the first gear 21 and is connected to the first gear 21 via a spline, so that the first gear 21 can transmit power to the drive shaft 31, and the drive shaft 31 can move up and down relative to the first gear 21. The top of the drive shaft 31 is guided by the first gear 21, and the bottom is guided by the pad 5, thus ensuring the stability of the drive shaft 31 during lifting and lowering.

[0036] Preferably, the first gear 21 is rotatably connected to the base 1 and is used to seal the cavity 11. The first gear 21 meshes with the second gear 22, which is also rotatably connected to the base 1. The second gear 22 meshes with the output shaft of the motor 23, which is located in the middle of the base 1. The power from the motor 23 is transmitted from the second gear 22 to the first gear 21 and then to the drive shaft 31, ultimately enabling the massage head 32 to rotate and massage.

[0037] Preferably, the base 1 has a left-right symmetrical structure, and the number of drive components 2 and massage components 3 is 2, which are arranged symmetrically.

[0038] In Embodiment 2, based on Embodiment 1, the cavity 11 can be a through structure, and a bottom cover is provided at the lower end of the base 1 to close the cavity 11, which facilitates the assembly of the airbag, drive shaft 31 and pad 5.

[0039] In summary, this utility model provides a massage device with a lifting massage head, which makes full use of the internal space of the massage device, simplifies the lifting structure of the massage head, reduces the thickness of the massage device, and saves space.
