[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example:

[0023] Reference Figures 1-4 This application relates to a constant temperature electric massage chair, including a seat 1 and a backrest 2. The backrest 2 is mounted on one side of the seat 1. It also includes two armrests and movable chair legs. The two armrests are respectively mounted on opposite sides of the seat 1, and the movable chair legs are retractably mounted on the bottom of the seat 1 via cylinders. Figure 2 As shown, the chair back 2 has a massage groove 3, and the massage groove 3 has two vertical connecting rods 5 arranged in a figure-eight shape. Each connecting rod 5 is slidably fitted with a connecting sleeve 6. Two massage heads for massage are rotatably mounted in the massage groove 3 and on the two connecting sleeves 6. Figure 3 and Figure 4 As shown, the massage head includes a rotating rod 7 and a massage plate 9 with massage balls 8. The rotating rod 7 is rotatably mounted on one of the connecting sleeves 6. The massage plate 9 is fixed to the end of the rotating rod 7 away from the connecting sleeve 6. The massage groove 3 is provided with a drive assembly for driving the two massage heads to move up and down and rotate simultaneously. The drive assembly includes a motor 10, a lead screw 11, a guide rod 12, and a mounting plate 13. The motor 10 is fixed to the backrest 2. The lead screw 11 is rotatably and vertically mounted in the massage groove 3. One end of the lead screw 11 is fixedly connected to the output end of the motor 10. The guide rod 12 is fixed in the massage groove 3 and parallel to the lead screw 11. One end of the mounting plate 13 is threaded onto the lead screw 11, and the other end of the mounting plate 13 is slidably mounted onto the guide rod 12. The mounting plate 13 has a sliding groove 14, and both rotating rods 7 pass through the sliding groove 14. Figure 4 As shown, each connecting sleeve 6 has a protrusion on one side that extends into the slide groove 14 and slides against the side wall of the slide groove 14. Each rotating rod 7 is fixed with a gear 15, and a rack 16 is fixed on one side of the slide groove 14. Both gears 15 mesh with the rack 16. This arrangement allows the motor 10 to drive the lead screw 11 to rotate, and the mounting plate 13 to slide between the lead screw 11 and the guide rod 12. Through the two connecting rods 5, the rotating rod 7 slides in the slide groove 14 on the mounting plate 13. While the rotating rod 7 is sliding, the meshing of the gears 15 and the rack 16 drives the rotating rod 7 and the massage plate 9 to rotate, so that the massage plate 9 can slide up and down while rotating. The motor 10 is a stepper motor 10 that can be programmed to rotate and reverse. The two connecting rods 5 are arranged in a figure-eight shape, which can effectively massage the fascia connection points according to the distribution of human muscles, conforming to ergonomic design.

[0024] like Figure 2 As shown, the chair back 2 is equipped with a thermostatic component for both heating and heat preservation. This component includes a heating plate 17 and several heat-conducting balls 18. The heating plate 17 is fixed to the chair back 2, and the heat-conducting balls 18 are rotatably positioned on the side of the heating plate 17 facing the human body. The side of the chair back 2 facing the human body, as well as the massage groove 3 and the periphery of the thermostatic component, are provided with heat-insulating cotton layers 19. After actual installation, a soft and elastic mesh layer is connected to the massage groove 3, and a breathable cotton layer of the same height as the heat-insulating cotton layer 19 is installed on the thermostatic component. The design of the heating plate 17 effectively heats the chair back 2. By combining sensors, control circuits, and a feedback adjustment mechanism, the heating plate 17 ensures that the temperature remains stable within the set range. This control method is similar to that disclosed in patent CN2088313U. The heat transfer path can be dispersed by several heat-conducting balls 18, reducing local high-temperature points and making the overall heating of the heating plate 17 more uniform. The contact between the heat-conducting balls 18 and the upper back of the person can also achieve a massage effect. The heating plate 17 and the motor 10 are both controlled by a control device, which can be set on one side of the seat 1. This kind of installation and connection is a common existing technology and will not be described in detail here.

[0025] Working principle:

[0026] When in use, the user simply moves the chair to a suitable position and sits down. When massage or heating is needed, the motor 10 drives the lead screw 11 to rotate, causing the mounting plate 13 to slide between the lead screw 11 and the guide rod 12. Through the setting of two connecting rods 5, the rotating rod 7 slides in the slide groove 14 on the mounting plate 13. While the rotating rod 7 is sliding, the meshing of the gear 15 and the rack 16 drives the rotating rod 7 and the massage plate 9 to rotate, so that the massage plate 9 slides up and down while rotating on its own axis. By turning on the electric heating plate 17, the backrest 2 is heated, which improves blood circulation in the user's back and reduces back fatigue after sitting for a long time.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
