[0002] Prolonged sitting or standing can cause muscle strain in the lower back, leading to pain and a range of common occupational ailments such as lower back and leg pain, and weakness in the limbs, especially for office workers who spend long hours hunched over at a desk. Most existing lumbar massagers offer either overall lumbar support, overall body vibration, or mechanical gear-driven rotary massage. The latter often only have a clockwise or counterclockwise rotation mode, resulting in a limited and monotonous massage effect and experience. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a single forward and reverse motor kneading massage device. This device has the advantage of allowing the two massage discs to rotate in opposite directions when the forward and reverse motors rotate in the forward direction, and allowing the two massage discs to rotate in the same direction when the forward and reverse motors rotate in the reverse direction, with one massage disc embedded in the other, thereby providing users with a more diverse massage experience.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a single forward and reverse motor kneading massage device, comprising a massager body, an outer disk and an inner disk coinciding with the rotation center line of the outer disk, the inner disk being embedded in the outer disk, and both the outer disk and the inner disk being provided with a plurality of massage protrusions; the massager body also comprises a gear set and a forward and reverse motor driving the gear set, wherein when the forward and reverse motor rotates forward, the gear set causes the outer disk to rotate in the opposite direction to the inner disk, and the gear set can also cause the outer disk to rotate in the same direction as the inner disk when the forward and reverse motor rotates in reverse.

[0005] The gear set is provided with a first gear that drives the output shaft of the forward and reverse motor. The outer teeth of the first gear mesh with the outer teeth of the second gear. The center line of the third gear coincides with the rotation center line of the fourth gear. The inner teeth of the second gear mesh between the inner teeth of the third gear and the outer teeth of the fourth gear. One-way bearings are provided on both the rotation center lines of the third gear and the rotation center lines of the fourth gear. The rotating rod passes through the one-way bearings. The rotating rod is assembled with the inner disk. The third gear is connected to the outer disk.

[0006] The output shaft of the reversible motor is a horizontally placed screw. The internal teeth of the first gear mesh with the external teeth of the second gear. The external teeth of the first gear are helical teeth and mesh with the screw.

[0007] The first gear and the second gear are both compound gears, the third gear is an internal gear, and the fourth gear is a spur gear.

[0008] The massager body contains a control circuit board and a battery electrically connected to the control circuit board, and the forward and reverse motor is electrically connected to the control circuit board.

[0009] The massager body is provided with a fixing strip, which is worn by the user to allow the massager body to fit against the human body.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0024] This embodiment relates to a single forward and reverse motor 4-kneading massage device, such as... Figure 1 and Figure 2 As shown:

[0025] The massager body 1 has an external housing. Inside the housing are a forward and reverse motor 4, a gear set 5, a control circuit board, and a battery. The forward and reverse motor 4 is placed horizontally, and its output shaft 41 is also placed horizontally. The output shaft 41 of the forward and reverse motor 4 is connected to the gear set 5. The forward and reverse motor 4 rotates forward or backward, so that the output part of the gear set 5 achieves different rotation modes. The forward and reverse motor 4 is electrically connected to the control circuit board, which can control the forward and reverse rotation of the forward and reverse motor 4 to rotate forward, reverse, or stop, and can also adjust the rotation speed of the forward and reverse motor 4. The battery is also electrically connected to the control circuit board, and the battery provides power to the entire massage device.

[0026] In this embodiment, the battery may be a rechargeable battery, thereby allowing the user to use the device repeatedly and for a long period of time.

[0027] It should be added that the casing has mounting slots 12 for assembling the inner disc 3 and the outer disc 2. The inner disc 3 is embedded in the center of the outer disc 2. The outer disc 2 can rotate clockwise or counterclockwise on the massager, and the inner disc 3 can rotate clockwise or counterclockwise on the outer disc 2. Both the inner disc 3 and the outer disc 2 are connected to a gear set 5, which is driven by a clockwise / counterclockwise motor 4. When the clockwise / counterclockwise motor 4 rotates clockwise, the two massage discs rotate in opposite directions, and when the clockwise / counterclockwise motor 4 rotates counterclockwise, the two massage discs rotate in the same direction. When the outer disc 2 and the inner disc 3 rotate in opposite directions, the user can obtain a kneading massage effect. When the outer disc 2 and the inner disc 3 rotate towards each other, the effect is similar to that of existing single-disc massagers.

[0028] Preferably, the gear set 5 includes: a first gear 51, a second gear 52, a third gear 53, a rotating rod 55, a first one-way bearing 57, and a second one-way bearing 56. The first gear 51 is driven by the output shaft 41 of the reversible motor 4. The external teeth of the first gear 51 mesh with the external teeth of the second gear 52. The center line of the third gear 53 coincides with the rotation center line of the fourth gear 54. The internal teeth of the second gear 52 mesh between the internal teeth of the third gear 53 and the external teeth of the fourth gear 54. A shaft hole 21 is provided on the rotation center line of the third gear 53, and the first one-way bearing 57 is provided in the shaft hole 21. A through hole 541 is provided on the rotation center line of the fourth gear 54, and the second one-way bearing 56 is provided in the through hole 541. The rotating rod 55 passes through the first one-way bearing 57 and the second one-way bearing 56, and the end of the rotating rod 55 away from the second one-way bearing 56 is fixedly assembled with the inner disk 3 at the top. The third gear 53 is connected to the outer disk 2.

[0029] It should be added that when the motor rotates forward, it drives the first gear 51 to rotate clockwise, which in turn drives the second gear 52 to rotate counterclockwise. The second gear 52 then drives the fourth gear 54 to rotate clockwise. At this time, the second one-way bearing 56 rotates clockwise along with the fourth gear 54, and is clamped to the shaft. The second one-way bearing 56 drives the inner disc 3 to perform a clockwise massage motion. The second gear 52 drives the third gear 53 to rotate counterclockwise, thus causing the outer disc 2 to perform a counterclockwise massage motion. The first one-way bearing 57 inside the outer disc 2 rotates counterclockwise along with the outer disc 2. At this time, the first one-way bearing 57 is in a free-spinning state relative to the shaft and does not interfere with the clockwise motion of the inner disc 3. Thus, the inner disc 3 and the outer disc 2 are performing massage motions in opposite directions.

[0030] When the motor reverses, it drives the first gear 51 to rotate counterclockwise, which in turn drives the second gear 52 to rotate clockwise. The second gear 52 then drives the fourth gear 54 to rotate counterclockwise. At this time, the second one-way bearing 56 rotates counterclockwise along with the fourth gear 54. The second one-way bearing 56 and the shaft are in a free-spinning state, and the second one-way bearing 56 does not drive the inner disc 3 to perform a counterclockwise massage action. The second gear 52 drives the third gear 53 to rotate clockwise, thus causing the outer disc 2 to perform a clockwise massage action. The first one-way bearing 57 inside the outer disc 2 rotates clockwise along with the outer disc 2. At this time, the first one-way bearing 57 is clamped to the shaft. The first one-way bearing 57 drives the shaft to rotate clockwise, and simultaneously, the inner disc 3 performs a clockwise massage action. At this time, the shaft rotates clockwise, and the second one-way bearing 56 rotates counterclockwise. The second one-way bearing 56 still rotates counterclockwise relative to the shaft and does not interfere with the clockwise movement of the inner disc 3. At this time, the inner and outer discs 2 are performing massage actions in the same direction.

[0031] It should be added that the output shaft 41 of the forward and reverse motor 4 is a horizontally placed screw. The internal teeth of the first gear 51 mesh with the external teeth of the second gear 52. The external teeth of the first gear 51 are helical teeth and mesh with the screw. The first gear 51 and the second gear 52 are both compound gears. The third gear 53 is an internal gear and the fourth gear 54 is a spur gear.

[0032] Preferably, the massager body 1 is provided with a shell, and the shell is provided with fixing strips 11 on both sides. The fixing strips 11 are preferably belts. The belts allow the user to hang the massager on the waist or other parts that need to be massaged, and make the outer plate 2 and inner plate 3 on the massager body 1 face the parts that need to be massaged, so that the user can use the massager without holding it.

[0033] In this embodiment, the inner disc 3 has three massage protrusions around its circumference, and the outer disc 2 has eight massage protrusions around its circumference. The massage protrusions are arranged in a semi-circular shape.

[0034] The working principle of this device is as follows: The device is worn on the area requiring massage via a belt, with the massage protrusions on the inner disc 3 and outer disc 2 aligned with the massage area. The device is then turned on. The control circuit board controls the forward and reverse motor 4 to rotate forward. When the motor 4 rotates forward, the gear set 5 connected to it causes the inner disc 3 and outer disc 2 to perform massage movements in the opposite direction. The control circuit board also controls the forward and reverse motor 4 to rotate in reverse. When the motor 4 rotates in reverse, the gear set 5 connected to it causes the inner disc 3 and outer disc 2 to perform massage movements in the same direction.

[0035] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
