Detailed Description

The invention is further described with reference to the following figures and embodiments:

in a first embodiment, referring to fig. 1 to 9, a neck massage machine core includes two massage components acting on the left and right sides of the neck of a human body, and the two massage components are driven by a motor 3 to work. Still include massage core casing, two massage subassemblies and motor 3 all set up in this casing, and two massage subassemblies are located motor 3 both sides. Each massage component comprises a gear set 4, a transmission shaft 52 and a massage head 1 driven by the transmission shaft 52; the motor 3 drives the gear set 4 to rotate, and the gear set 4 drives the transmission shaft 52 to rotate so as to drive the massage head 1 to rotate. In a typical neck massager cartridge, the drive shaft 52 is fixed to the housing 2. Thus, the interval between the two massage heads 1 is fixed. In this embodiment, each massage assembly further includes a bottom case 5 and a positioning assembly 6, and the transmission shaft 52 is rotatably disposed on the bottom case 5. The bottom shell 5 is selectively rotatable about the gear set 4, and the bottom shell 5 is driven to rotate about the gear set 4 by the positioning assembly 6. The positioning assembly 6 also has the function of fixing the rotation position of the bottom shell 5. The two bottom shells 5 rotate relative to the corresponding gear sets 4, so that the massage heads 1 on the two massage assemblies are close to or far away from each other.

The transmission shaft 52 for driving the massage heads 1 to rotate is arranged on the bottom shell 5, one end of the bottom shell 5 can rotate and be positioned relative to the gear set 4, so that the massage heads 1 of the two massage assemblies can not only be driven by the gear set 4, but also the distance between the massage heads 1 of the two massage assemblies can be adjusted, and the massage device is suitable for different users to massage.

In practical implementation, one end of the bottom shell 5 is provided with a hinge hole and is hinged with a central shaft 41 of the gear set 4, the central shaft 41 is fixed in the housing 2, and the bottom shell 5 rotates around the central shaft 41 of the gear set 4. Because the articulated one end of drain pan 5 shares a center pin 41 with gear train 4, can reduce the inside spare part use of casing 2, reduced the occupation to casing 2 inner space.

Preferably, a transmission gear 51 is fixed to a transmission shaft 52 on the bottom case 5 in a circumferential direction. The transmission gear 51 is meshed with the gear set 4, and the transmission shaft 52 is driven by the gear set 4 to rotate.

Further, the motor 3 is a double-output shaft motor 3, and output shafts at two ends are respectively provided with a worm 31.
