[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-8 As shown, a hand massage device includes a housing 10, a drive shaft 20, a drive mechanism 30, and a hand massage chamber 40, which constitute the basic structure of the hand massage device.

[0032] The housing 10 has a receiving cavity, and a drive shaft 20 is rotatably installed in the receiving cavity. The drive shaft 20 includes a vertical section 21 that is vertically arranged in the receiving cavity and an inclined section 22 that extends out of the receiving cavity. The inclined section 22 is arranged at an angle to the vertical section 21. A drive mechanism 30 is disposed in the receiving cavity and is connected to the drive shaft 20. The hand massage chamber 40 is connected to the outer periphery of the inclined section 22 and can rotate synchronously with the inclined section 22. The housing 10 has an upwardly protruding limiting post 11, and the handle massage chamber is provided with a limiting groove 41. The limiting post 11 extends into the limiting groove 41 and is limited by the limiting groove 41 to limit the swing amplitude of the hand massage chamber 40. The hand massage chamber 40 is also provided with an airbag massage assembly 42.

[0033] When the drive mechanism 30 drives the drive shaft 20 to rotate, the inclined section 22 of the drive shaft 20 will rotate along the rotation axis of the drive shaft 20, that is, along the rotation axis of the vertical section 21. Since the inclined section 22 and the vertical section 21 are set at an angle, the hand massage chamber 40 installed on the inclined section 22 will swing around the inclined section 22. At the same time, the swing amplitude of the hand massage chamber 40 is limited by the limiting post 11 and the limiting groove 41, thereby realizing the swing and stretching function of the hand massage chamber 40.

[0034] In some embodiments, a flange 23 is provided between the vertical section 21 and the inclined section 22. The upper end of the flange 23 has an inclined support surface that is consistent with the inclination angle of the inclined section 22. The inclined support surface is used for positioning and supporting the hand massage chamber 40. That is, the inclined support surface plays a positioning role for the hand massage chamber 40 on the one hand, and a supporting role for the hand massage chamber 40 on the other hand.

[0035] In some embodiments, the hand massage chamber 40 is connected to the inclined section 22 via a bearing 47, which serves to support the hand massage chamber 40 and reduce friction.

[0036] In some embodiments, the hand massage chamber 40 is provided with a massage channel 43 for a human hand to insert into. The airbag massage assembly 42 includes an upper massage airbag 421 disposed at the upper end of the massage channel 43 and a lower massage airbag 422 disposed at the lower end of the massage channel 43. The hand massage chamber 40 has an upper mounting cavity 44 for accommodating the upper massage airbag 421 and a lower mounting cavity 45 for accommodating the lower massage airbag 422. The hand massage chamber 40 is provided with a pipeline channel 46. The pipeline channel 46 includes an upper connecting channel 461 for the upper mounting cavity 44 and the lower mounting cavity 45 and a lower connecting channel 462 for connecting the lower mounting cavity 45 and the accommodating cavity. The upper mounting cavity 44 and the lower mounting cavity 45 have a cloth cover or leather cover on one side corresponding to the massage channel 43.

[0037] In some embodiments, the lower connecting channel 462 includes a limiting groove 41 and a through groove that passes through the limiting post 11. The pipes of the upper massage airbag 421 and the lower massage airbag 422 are led out through the limiting groove 41 and the through groove and connected to the control module. The control module may be integrated into the housing 10 or integrated into the massage chair body.

[0038] In some embodiments, the angle between the inclined segment 22 and the vertical segment 21 is 8°-11°. In this embodiment, the angle between the inclined segment 22 and the vertical segment 21 is preferably 9°. This ensures that when the hand massage chamber 40 swings relative to the horizontal plane, the vertical swing angle of the hand massage chamber 40 is 9°, which helps to increase the comfort of the swing massage and improve the swing massage effect.

[0039] In some embodiments, the drive mechanism 30 includes a drive motor 31 and a transmission mechanism 32 connected to the output end of the drive motor 31. The transmission mechanism 32 includes a first transmission gear 321, a second transmission gear 322, and a third transmission gear 323. The first transmission gear 321 and the second transmission gear 322 are coaxially arranged and rotatably installed in the accommodating cavity. The third transmission gear 323 is fixedly connected to the vertical section 21 and is drivenly connected to the second transmission gear 322. The first transmission gear 321 is drivenly connected to the output end of the drive motor 31. Specifically, the first transmission gear 321 and the output end of the drive motor 31 are worm gear mechanisms, and the second transmission gear 322 and the third transmission gear 323 are spur gears.

[0040] In some embodiments, a soft rubber sleeve 50 is connected between the housing 10 and the hand massage chamber 40. The limiting post 11 and the inclined section 22 are covered inside the soft rubber sleeve 50. The soft rubber sleeve 50 serves to protect and prevent dust, thus avoiding the problem of pinching the hand.

[0041] In some embodiments, a detection mechanism is provided inside the housing 10. The detection mechanism includes a code disk 12 and a grating 13. The code disk 12 is disposed on the output end of the motor 31 or the transmission mechanism 32 so that the code disk 12 rotates synchronously with the output end of the motor 31 or the transmission mechanism 32. The code disk 12 is provided with a groove 121. The grating 13 is fixedly installed inside the housing 10 and cooperates with the code disk 12 to detect the swing position of the hand massage chamber 40. In this embodiment, the code disk 12 is coaxially disposed with the third transmission gear 323. The grating 13 has a groove into which part of the code disk 12 extends. The position of the groove 121 of the code disk 12 corresponding to the position of the grating 13 is the starting position of the code disk. By detecting the rotation position of the code disk 12 through the grating 13, the rotation amplitude and direction of the hand massage chamber 40 can be precisely controlled.

[0042] A massage chair includes a massage chair body and a hand massage device as described in any one of the above, wherein the hand massage device has two sets and is respectively arranged on both sides of the massage chair body.

[0043] In summary, this utility model has the following beneficial effects:

[0044] The hand massage device and massage chair of this application can not only realize the airbag compression massage function of the hand, but also realize the rocking and stretching function of the hand, which greatly enriches the massage function and effectively enhances the massage effect.
