[0033] refer to Figure 1-14 This invention provides a detailed description of a head therapy device, its preferred embodiments, and other embodiments.
[0034] In a preferred embodiment, refer to the appendix. Figure 1-8This utility model discloses a head therapy device, characterized in that it includes a chair 1, a track 2, and a head therapy device 3. The chair 1 includes a fixed seat 11 and a backrest 12. The head therapy device 3 includes a base 31, a lifting mechanism 32, a robotic arm 33, and a head therapy module 34. The fixed seat 11 is used to support the user on the working ground and has a cushion for the user to sit on. The backrest 12 is located on one side of the fixed seat 11, and the tilt of the backrest 12 relative to the fixed seat 11 is adjustable. In this embodiment, the tilt of the backrest 12 refers to the angle α formed between the backrest 12 and the fixed seat 11. The track 2 is located on one side of the fixed seat 11, with one end close to the fixed seat 11 and the other end extending away from the backrest 12 in the direction of adjusting the backrest 12. In this embodiment, the backrest 12 is located behind the fixed seat 11. The backrest 12 can be tilted in the front-back direction. One end of the track 2 is located near the fixed base 11, and the other end of the track 2 extends backward. The base 31 is located above the track 2 and can move along the track 2, that is, the base 31 moves along the track 2 in the front-back direction. The lifting mechanism 32 is mounted on the base 31. The robotic arm 33 is mounted on the lifting mechanism 32 and can move up and down with the lifting mechanism 32. The head therapy module 34 is located on the robotic arm 33. The lifting mechanism 32 is provided with a connecting rod 321. The connecting rod 321 is movably connected to the backrest 12. When the backrest 12 is tilted relative to the fixed base 11, the backrest 12 drives the lifting mechanism 32 to move up and down with the backrest 12 through the connecting rod 321. At the same time, the backrest 12 drives the base 31 to move horizontally along the track 2 through the connecting rod 321. The lifting mechanism 32 is equipped with a connecting rod 321, which is movably connected to the backrest 12. The robotic arm 33 is mounted on the lifting mechanism 32, and the base 31 is located above the track 2. When the backrest 12 is tilted relative to the fixed seat 11, the backrest 12 drives the lifting mechanism 32 to move up and down with the backrest 12 via the connecting rod 321, so that the robotic arm 33 maintains a predetermined height relative to the backrest 12. At the same time, the backrest 12 drives the base 31 to move along the track 2 via the connecting rod 321, so that the robotic arm 33 maintains a predetermined horizontal distance relative to the backrest 12, causing the head therapy module 34 to move with the backrest 12, so that the head therapy module 34 is maintained in its preset position relative to the backrest 12. This eliminates the need to re-analyze and calculate the distance between the head therapy module 34 and the backrest 12, and then adjust the head therapy module 34 to the preset position, thereby simplifying the structure of the head therapy device and reducing production costs.The preset position of the head therapy module 34 refers to its initial position relative to the backrest 12 when the physiotherapy module 34 starts working. The predetermined height of the robotic arm 33 relative to the backrest 12 refers to the height position of the robotic arm 33 relative to the backrest 12 when the head therapy module 34 is in the preset position. The predetermined horizontal distance of the robotic arm 33 relative to the backrest 12 refers to the horizontal position of the robotic arm 33 relative to the backrest 12 when the head therapy module 34 is in the preset position. The head therapy module 34 can be a combing module or a massage module. In a preferred embodiment, refer to the appendix. Figure 1-3 In this invention, the backrest 12 of the head therapy device is located behind the fixed base 11, and the track 2 is located on the left or right side of the fixed base 11. One end of the connecting rod 321 is rotatably connected to the backrest 12, and the other end of the connecting rod 321 is fixedly connected to the lifting mechanism 32. By rotatably connecting one end of the connecting rod 321 to the backrest 12, when adjusting the backrest 12, the connecting rod 321 can rotate relative to the backrest 12, avoiding the backrest 12 exerting a torsional force on the connecting rod 321, which would cause the connecting rod 321 to twist and affect the driving of the lifting mechanism 32 to move up and down.
[0035] In a preferred embodiment, refer to the appendix. Figure 3-4 The backrest 12 of the head therapy device of this utility model is provided with a first bushing 121. The connecting rod 321 includes a rotating rod 3211. One end of the rotating rod 3211 is provided with a stop 3212. The first bushing 121 is sleeved on the rotating rod 3211 and abuts against the stop 3212. The rotating rod 3211 rotates relative to the first bushing 121. The other end of the rotating rod 3211 is fixedly connected to the lifting mechanism 32. The length of the rotating rod 3211 is greater than the distance between the stop 3212 and the lifting mechanism 32. By setting the first bushing 121 to be fitted onto the rotating rod 3211, when adjusting the backrest 12, the connecting rod 321 can rotate relative to the first bushing 121, thus preventing the backrest 12 from exerting a torsional force on the connecting rod 321, which would cause the connecting rod 321 to twist and affect the driving of the connecting rod 321 to move the lifting mechanism 32 up and down. At the same time, by setting the length of the rotating rod 3211 to be greater than the distance between the stop 3212 and the lifting mechanism 32, the first bushing 121 can flexibly adjust its position in the axial direction of the rotating rod 3211, thus preventing the rotating rod 3211 from exerting a pulling force on the lifting mechanism 32 in its axial direction.

When the backrest is tilted relative to the fixed seat, the backrest drives the lifting mechanism to move up and down with the backrest through the connecting rod, so that the robotic arm maintains a predetermined height relative to the backrest. At the same time, the backrest drives the base to move along the track through the connecting rod, so that the robotic arm maintains a predetermined horizontal distance relative to the backrest, and the head therapy module moves with the backrest to keep the head therapy module in its preset position relative to the backrest. It is not necessary to re-analyze and calculate the distance between the head therapy module and the backrest and then adjust the head therapy module to the preset position, thereby simplifying the structure of the head therapy device and reducing production costs.
