[0002] Back massagers usually fit the user's back curve, providing more comfortable support and massage effects. They can automatically adjust according to different user's body shapes. Many back massagers are small and light, easy to carry and store. Users can use them at home, in the office or on the go to provide a comfortable back massage.

[0003] Back massagers are usually equipped with a variety of massage modes and strengths, such as kneading, tapping, vibration, etc. Users can choose the appropriate massage method according to their personal preferences and needs;

[0004] However, during the massage process, existing back massagers can usually only achieve point massage and cannot achieve the wandering massage function, resulting in a smaller massage area and reduced massage experience. Some massagers that can achieve multi-point mobile massage have complex structures and high energy consumption, which affects the user experience. Summary of the invention

[0005] The object of the present invention is to provide a back massager to solve the above-mentioned problems.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

After the motor is started, the rotating shaft at the output end drives the kneading double-linked teeth to rotate through the worm, the kneading double-linked teeth drive the transmission double-linked teeth to rotate, the transmission double-linked teeth drive the bevel gear on the long shaft to rotate and then drive the long shaft to rotate. At this time, the long shaft drives the two eccentric wheels to rotate, and the eccentric wheels push the swing arm on the support seat to swing, so that the double massage heads can achieve massage and kneading actions;

[0008] While massaging and kneading, that is, the long axis is rotating, it also drives the spur gears at both ends to rotate, and the spur gears can drive the traveling double teeth to rotate. Since the traveling double teeth are meshed with the rack, at this time, the movement housing can be controlled to move on the rack, thereby realizing the function of mobile massage.

[0009] As a further solution of the present invention: the inner rotation of the movement housing is provided with transmission double-linked teeth;

[0018] Connecting rods are symmetrically arranged at both ends below the base, the upper end of the connecting rods penetrates a connecting rubber ring, and the upper end of the connecting rods is provided with a single massage head;

[0019] After the double-headed brushless motor is powered on, the output shafts at both ends drive the eccentric block to rotate, and the eccentric block pulls the connecting rod through the eccentric bearing to achieve up and down reciprocating movement. The connecting rubber ring supports the connecting rod. At this time, the connecting rod drives the single massage head to move up and down to achieve the knocking function.

[0020] It should be noted that a rolling bearing is also provided on one side of the connecting rod and above the eccentric bearing. During the massage process, when the device is under light load, the connecting rod can be supported by connecting the rubber ring. When the device is under heavy load, the rolling bearing can cooperate with the rubber ring to support the connecting rod at the same time, thereby ensuring the stability of the entire device and the massage effect.

[0027] Beneficial effects of the present invention:

[0028] In the present invention, after the motor is started, the rotating shaft at the output end drives the kneading double-linked teeth to rotate through the worm, the kneading double-linked teeth drive the transmission double-linked teeth to rotate, the transmission double-linked teeth drive the bevel gear on the long shaft to rotate and then drive the long shaft to rotate, at this time, the long shaft drives the two eccentric wheels to rotate, the eccentric wheels push the swing arms on the support seat to swing, and the double massage heads can achieve massage and kneading actions;

[0029] While massaging and kneading, that is, the long shaft is rotating, it also drives the spur gears at both ends to rotate, and the spur gears can drive the walking double-linked teeth to rotate. Since the walking double-linked teeth are meshed and connected with the rack, at this time, the movement housing can be controlled to move on the rack, thereby realizing the function of mobile massage;

[0030] Through a single motor for transmission, two sets of double massage heads can realize the function of twisting and kneading massage, and at the same time realize the walking function, realizing the wandering massage function, and the structure is simple, and the walking movement component can increase the massage area during the movement process, which is suitable for different people and different body parts;
