[0002] A leg therapy massage chair is a device specially designed to relax and relieve leg muscle tension and fatigue. It is usually equipped with multiple functions, such as vibration, rolling, kneading, etc., to simulate the techniques of professional masseuses to perform deep massage on the calves, thighs and even feet. This equipment can not only help improve blood circulation and promote metabolism, but also effectively reduce the soreness caused by standing or walking for a long time. It is very beneficial for people who often feel discomfort in the lower limbs. Modern leg therapy massage chairs are often designed based on ergonomic principles, which can better fit the curve of the human body, ensuring comfort and optimal results during use. Some high-end models also incorporate intelligent control technology, allowing users to adjust the massage intensity, speed and mode according to their needs to achieve a personalized experience.

[0052] Working principle of the present invention:

[0053] When the user's feet step into the foot protection groove 201, the device is started, the front and rear drive components 9 are driven, and the output shaft of the rear motor 901 drives the worm 903 to spin, and then the spinning worm 903 transmits the torque force to the driving gear 904 and the driven gear 905 meshing with it, so that the driven gear 905 can carry the first transmission shaft 302 and the eccentric wheels 303 at both ends to rotate coaxially. The rotation direction of the first transmission shaft 302 and the eccentric wheel 303 can be changed by switching the transmission direction of the motor 901. In the stage of applying pressure to the sole of the foot, the eccentric wheel 303 is clockwise. The lifting rod 402 rotates in the same direction, during which the pull rod at the edge of the eccentric wheel 303 pulls the swing rod 304 to swing back from right to left, so that the bottom end of the lifting rod 402 is pushed by the swing rod 304 and rotates around the axis with the top rotation axis of the lifting rod 402 as the center, so that the bottom plate 401 assembled at the bottom end of the lifting rod 402 and the components carried above it are lifted as a whole. When the perforation of the induction code disk 501 falls between the light-sensing transmitter and the receiver of the optical coupling induction frame 502, the signal communication between the light-sensing transmitter and the receiver is restored, and it is determined that the massage part 602 and the second massage roller cover 702 have reached the massage area of ​​the foot protection groove 201 at this time. Figure 3 In the display state, the control module receives the information output by the receiver and controls the motor 901, controls the rear motor 901 to stop driving, and makes the front massage component 6 and the rear massage component 7 hover at a preset angle. At this time, the sole of the user's foot is subjected to constant pressure, and at the same time, the front drive component 9 continuously drives the massage part 602 and the second massage roller cover 702 to spin. The rotating massage part 602 and the second massage roller cover 702 can massage the sole of the user's foot, which plays a role in relaxing and relieving the tension and fatigue of the leg muscles;

[0054] At the same time, the rotating massage part 602 can carry the I-shaped rotating ring 6032 and the guide scraper 6035 to rotate coaxially with the help of the guide tube 6023. The rotating guide scraper 6035 turns over the physiotherapy medicine or massage oil in the liquid cavity of the heating element 6031, so that the medicine in the liquid cavity is quickly and evenly heated. When the finger pressure plate 6024 rotates close to the sole of the user's foot, the finger pressure plate 6024 will be pressed and slide downward along the lifting groove, and then push the guide tube 6023 outward, so that the guide tube 6023 can slide outward along the translation groove. The extended guide tube 6023 can press the spring 6034 and push open a corner of the corresponding sealing ring 6033, so that the physiotherapy medicine preheated in the heating element 6031 can be heated along the guide scraper 6035. The vortex discharge is introduced into the guide tube 6023 through the open hole of the I-shaped rotating ring 6032. The adsorbent cotton 6025 can adsorb the therapeutic agent collected in the guide tube 6023 and apply it to the massaged skin layer to achieve automatic drug dispensing. The agent molecules penetrate into these damaged areas to promote blood circulation, accelerate metabolism and reduce inflammatory response. When the acupressure plate 6024 is evacuated from the sole of the user's foot, the guide tube 6023 and the acupressure plate 6024 can be reset under the elastic force of the spring 6034, so that the sealing ring 6033 seals the through hole of the I-shaped rotating ring 6032 again, and cooperates with the guide scraper 6035 to continue to heat the therapeutic agent in the liquid cavity of the heating element 6031, waiting for the next cycle of pressing and applying operation.
