[0021] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a pain reliever, including a wheel-shaped outer shell 1, with two massage heads 2 inside the wheel-shaped outer shell 1. Each massage head 2 has a connecting block 3 installed inside it. Two mounting plates 4 are installed on the outer walls of each of the two connecting blocks 3. A buffer assembly for pushing the massage is provided on one side of each mounting plate 4. A main rod 10 is located inside the wheel-shaped outer shell 1. Two cams 9 are installed on the rod wall of the main rod 10. Follower wheels 8 are rotatably installed on the outer walls of each of the two cams 9. Support plates 11 are rotatably installed at both ends of the main rod 10. Two fixing plates 13 are installed on one side of each of the two support plates 11. Multiple fixing plates 13 are installed on the wheel-shaped outer shell 1. A drive assembly is provided at one end of the main rod 10. The pain reliever is small and portable. A drive motor 15 drives the main rod 10 to rotate the cams 9, thereby causing the follower wheels 8 to flip up and down. Simultaneously, the flipping motion pushes the massage heads 2 up and down, thus providing a massage effect on the sore areas of the body. During massage, the force of the buffer spring 6 inside the buffer assembly, combined with the massage heads 2, enhances the massage effect.

[0022] like Figure 2As shown, the buffer assembly includes a hollow plate 7, which is mounted on the follower wheel 8. A buffer spring 6 is installed inside the hollow plate 7, and a baffle 5 is installed at the other end of the buffer spring 6. One side of the mounting plate 4 is respectively mounted on the corresponding baffle 5. One end of the buffer spring 6 inside the hollow plate 7 is connected to the baffle 5. The baffle 5 is connected to the mounting plate 4. The mounting plate 4 is mounted on the connecting block 3. The connecting block 3 is slidably mounted in the limiting groove 12 on one side of the support plate 11. When the follower wheel 8 flips up and down, the connecting block 3 is driven to move up and down through the buffer spring 6, the baffle 5, and the mounting plate 4. The connecting block 3 drives the massage head 2 to move up and down in the lifting port 18 on one side of the inner wall of the groove 17, thereby realizing the massage action of the massage head 2 on the sore parts of the human body.

[0023] The drive assembly includes a drive shaft 14, which is rotatably mounted inside the corresponding support plate 11. One end of the drive shaft 14 is fixed to one end of the main rod 10, and the other end of the drive shaft 14 is equipped with a drive motor 15. A heat sink 16 is provided on the outside of the drive motor 15. Both the drive motor 15 and the heat sink 16 are mounted on the wheel-shaped housing 1. When the drive motor 15 starts to work, its output shaft is fixedly connected to one end of the main rod 10 through the drive shaft 14. The main rod 10 starts to rotate under the drive of the drive motor 15. Two cams 9 are installed on the wall of the main rod 10. The cams 9 rotate together with the main rod 10 and dissipate heat from the operating equipment through the heat sink 16.

[0024] like Figure 1 and 2 As shown, each of the two support plates 11 has two limiting grooves 12 on one side. A connecting block 3 is slidably installed inside a set of limiting grooves 12. The limiting grooves 12 guide the vertically moving connecting block 3 and massage head 2, making their operation more stable. A groove 17 is provided on one side of the wheel-shaped outer shell 1. The interior of the groove 17 conforms to ergonomic design. Multiple massage protrusions 20 are provided on one side of the inner wall of the groove 17. Two lifting ports 18 are provided on one side of the inner wall of the groove 17. The two massage heads 2 are slidably installed inside the corresponding lifting ports 18. Massage pads 19 are covered on the outside of the two massage heads 2. When the massage head 2 moves up and down in the groove 17 to massage, the massage protrusions 20 will also come into contact with the human body, increasing the massage effect and comfort. At the same time, the massage pads 19 on the outside of the massage head 2 further improve the comfort of the massage, allowing the massage head 2 to better fit the sore parts of the human body and achieve a better pain relief effect.

[0025] like Figure 2 and 3As shown, a signal receiver 21 is installed on one side of the wheel-shaped housing 1. The signal receiver 21 is electrically connected to a control handle 22. The control handle 22 is equipped with two indicator lights 23, a speed control button 24 for forward and reverse rotation, and multiple directional buttons 25 for speed adjustment. When the speed control button 24 or directional button 25 on the control handle 22 is pressed, a control signal is sent to the signal receiver 21. At the same time, the indicator light 23 will show that the signal has been sent. After receiving the signal, the signal receiver 21 will control the drive motor 15 to rotate forward and reverse or accelerate and decelerate according to the corresponding instructions, thereby realizing the control of the speed and direction of the massage head 2, meeting the needs of different users for massage intensity and mode. The signal receiver 21 is installed on one side of the wheel-shaped housing 1. The signal receiver 21 is electrically connected to the control handle 22. The control handle 22 is equipped with two indicator lights 23, a speed control button 24 for forward and reverse rotation, and multiple directional buttons 25 for speed adjustment.

[0026] The working principle is as follows: In actual use, when the pain reliever is activated, the drive motor 15 in the drive assembly starts working. The drive motor 15 is mounted on the wheel-shaped housing 1, and its output shaft is fixedly connected to one end of the main rod 10 through the transmission shaft 14. The main rod 10 starts to rotate under the drive of the drive motor 15. Two cams 9 are installed on the wall of the main rod 10. The cams 9 rotate together with the main rod 10. Follower wheels 8 are rotatably installed on the outer wall of the cams 9. The follower wheels 8 will flip up and down as the cams 9 rotate. A hollow plate 7 is installed on the moving wheel 8. One end of the buffer spring 6 inside the hollow plate 7 is connected to the baffle 5. The baffle 5 is connected to the mounting plate 4. The mounting plate 4 is installed on the connecting block 3. The connecting block 3 is slidably installed in the limiting groove 12 on one side of the support plate 11. When the moving wheel 8 flips up and down, the buffer spring 6, the baffle 5 and the mounting plate 4 drive the connecting block 3 to move up and down. The connecting block 3 drives the massage head 2 to move up and down in the lifting port 18 on one side of the inner wall of the groove 17, thereby realizing the massage action of the massage head 2 on the sore parts of the human body.

[0027] Massage intensity adjustment principle: During the massage, the buffer component plays a role in adjusting the massage intensity. The buffer spring 6 is located inside the hollow plate 7. When the massage head 2 is subjected to greater pressure, the buffer spring 6 will be compressed, thereby buffering some of the pressure and preventing excessive massage intensity from causing discomfort to the human body. When the pressure on the massage head 2 decreases, the buffer spring 6 will return to its original shape, maintaining a certain massage intensity, making the massage effect more comfortable and even. This pain reliever drives the cam 9 to rotate through the drive motor 15, thereby enabling the massage head 2 to move up and down for massage with the cooperation of the buffer component, achieving the purpose of effectively relieving pain.
