The back cushion 3 is detachably arranged between the first clamping block 11 and the second clamping block 13. The sliding of the slider 2 drives the telescopic rod 8 to rotate and extend, thereby driving the first mounting shaft 10 to rotate. The rotation of the first mounting shaft 10 drives the first clamping block 11 and the second clamping block 13, thereby driving the back cushion 3 to rotate. This method specifically realizes the rotation of the back cushion 3.

[0023] like Figure 2 and Figure 3 As shown, the back cushion 3 includes two main bodies 301, two first mounting parts 302, and two second mounting parts 303.

This specific rotation method is mechanized and automated, making it easy to operate.

[0025] like Figure 2As shown, the leg massage block 4 includes a connecting portion 401 and a working portion 402, the connecting portion 401 of the leg massage block 4 is fixedly sleeved on the rotating shaft 17, the working portion 402 of the leg massage block 4 includes a long plate and two side plates fixedly arranged on both sides of the long plate, the two side plates of the working portion 402 are fixedly provided with a second motor 18, the output end of the second motor 18 is connected to a second transmission shaft 19, a third mounting block 20 is fixedly provided in the middle of the long plate of the working portion 402, the two second transmission shafts 19 are respectively rotated through the working portion 402 provided on the corresponding leg massage block 4, and are rotated on the third mounting block 20; the second transmission shaft 19 is a threaded rod of a screw rod structure, and each of the second transmission shafts 19 is divided into four rods The thread directions of the two adjacent rod segments are opposite, and the massage plates 21 are threadedly connected to the four rod segments of each second transmission shaft 19. The four massage plates 21 on the four rod segments of each second transmission shaft 19 are grouped in twos, and massage the two calves of the same user respectively. There is a circuit inside the two massage plates 21 in each group. The circuit converts electrical energy into current through a power supply, and then generates a changing magnetic field through an electromagnetic coil, thereby stimulating the emission of current pulses. These current pulses are transmitted to the human muscles through the conductive electrodes on the massage plates 21, thereby stimulating and treating the user's calf area, promoting local blood circulation, exciting local muscle nerve tissue, and improving the symptoms of local soreness, and the side wall of each massage plate 21 is in contact with the long plate of the working part 402.

[0026] Two second motors 18 and two second transmission shafts 19 are provided to accommodate two users lying on the sofa body 1 for massage at the same time, and the two users can independently adjust the position of the massage plate 21, thereby improving practicality.

The protective covers 25 enclose the first motor 5, the first transmission shaft 6, the slider 2, the telescopic rod 8, and the like. The provision of the protective covers 25 prevents the first transmission shaft 6 and other components from being exposed and potentially entangled in the user's clothes, hair, hands, etc., thereby avoiding safety hazards.

[0027] Working principle:

[0028] Before use, the two first mounting parts 302 are placed in the first clamping block 11 and the second clamping block 13, and then bolts are screwed into the first mounting part 302 and the first clamping block 11, and the first mounting part 302 and the second clamping block 13 respectively, so that the cushion 3 is firmly installed on the sofa body 1, and then the zippers on the two second mounting parts 303 are pulled to install the cushion 3.

[0029] During use, the user starts the first motor 5, and the output end of the first motor 5 drives the first transmission shaft 6 to rotate. The rotation of the first transmission shaft 6 drives the slider 2 to slide toward the leg massage block 4. The sliding of the slider 2 drives the telescopic rod 8 to extend and rotate. The extension and rotation of the telescopic rod 8 drives the first installation shaft 10, the first clamping block 11, the second installation shaft 12, the second clamping block 13, and the cushion 3 to rotate, thereby adjusting the inclination angle of the cushion 3;

[0030] The rotation of the first transmission shaft 6 also drives the first bevel gear 14 to rotate, and the rotation of the first bevel gear 14 drives the second bevel gear 15 and the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 drives the connecting portion 401 on the leg massage block 4 to rotate, and the rotation of the connecting portion 401 drives the leg massage block 4 to rotate, thereby adjusting the inclination angle of the leg massage block 4, coordinating with the change in the inclination angle of the back cushion 3, and then the user can adjust to a suitable lying position;

[0031] Then the user starts one of the second motors 18, and the output end of the second motor 18 drives the corresponding second transmission shaft 19 to rotate. The rotation of the second transmission shaft 19 drives four massage plates 21 to move two by two close to the two calves of the user and surround the user's calves. The massage plates 21 use current pulses to stimulate and treat the user's calves, and the entire operation is completed.
