[0033] Refer to Figure 3 And Figure 4The driving assembly comprises a driving motor 61 fixedly connected to the inner wall of the upper portion of the shell 51 as the power source of the whole massage mechanism, the rotation of the output shaft of the driving motor 61 drives the transmission wheel 62 to rotate, and then the power is transmitted to the driven wheel 52 through the belt 63, finally the transmission roller 55 rotates, realizing the active operation of the massage mechanism, controlling the rhythm, intensity and duration of the massage and other parameters to meet the needs of different users. The driving motor 61, the technology is prior art, therefore, will not be described here, the left side of the output shaft of the driving motor 61 is fixedly connected with the transmission wheel 62, which rotates synchronously with the driving motor 61, and the transmission wheel 62 can effectively drive the driven wheel 52 to rotate through the belt 63, realizing power transmission. The transmission wheel 62 is drivingly connected with the belt 63 outside, connecting the driven wheel 52 and the transmission wheel 62 for power transmission. The belt 63 is drivingly connected outside the driven wheel 52.

[0034] Referring to Figure 4 The auxiliary assembly comprises a fixed plate 71 for providing a mounting and rotating support point for the stabilizing wheel 72. The fixed plate 71 is arranged outside the two groups of transmission rollers 55. The fixed plate 71 is provided with two groups, and the opposite sides of the two groups of fixed plates 71 are rotatably connected with the stabilizing wheels 72. There is a certain friction force between the stabilizing wheels 72 and the conveying belt 53. When the conveying belt 53 moves, the stabilizing wheels 72 can assist in supporting the conveying belt 53, adjusting the tension and movement direction of the conveying belt 53, and keeping the conveying belt 53 in a stable and uniform movement state, thereby improving the stability and comfort of the massage. The anti-skid strip is arranged close to the inner side of the conveying belt 53. The anti-skid strip is used for increasing the friction force between the transmission roller 55 and the conveying belt 53, and improving the transmission efficiency. The stabilizing wheel 72 is provided with a plurality of groups, and the plurality of groups of stabilizing wheels 72 slide on the inner side of the conveying belt 53.

[0035] Referring to Figure 2 and Figure 3 The outer frame 1 is provided with an adjusting assembly close to the rear side of the shell 51. The adjusting assembly comprises a bottom plate 81 for providing a mounting base and support structure for the compression spring 82 and the sliding block 83, and is conveniently disassembled by being bolted to the outer frame 1. The bottom plate 81 is fixedly connected to the inner side of the outer frame 1. The sliding block 83 is slidingly connected to the inner wall of the front side of the bottom plate 81 and directly contacts the shell 51, which can drive the shell 51 to move. The sliding block 83 is elastically connected with the bottom plate 81 through the compression spring 82. The compression spring 82 is provided with a plurality of groups. One end of the plurality of groups of compression springs 82 is fixedly connected to the inner wall of the bottom plate 81, and the other end of the plurality of groups of compression springs 82 is fixedly connected to the rear side of the sliding block 83. Through the elastic force, the position of the massage mechanism can be adjusted to a certain extent, so that it always remains at a relatively appropriate working position, thereby improving the accuracy and effectiveness of the massage. The front side of the sliding block 83 is attached to the rear side of the shell 51.

[0036] Working principle: in use, first, the user will put his feet on the foot pad 3, and then use the strap 2 on the upper part of the outer frame 1 to fix the whole heel pad in a suitable position of the leg, when the massage function is needed, the driving motor 61 is connected to the power supply, and its output shaft starts to rotate, driving the transmission wheel 62 fixedly connected therewith to rotate synchronously, and through the transmission of the belt 63, the power is transmitted to the driven wheel 52, and then the transmission roller 55 starts to rotate.

[0037] When the transmission roller 55 rotates, the conveying belt 53 can stably follow the rotation of the transmission roller 55 to make a circulating motion, and the plurality of massage rollers 54 with protrusions installed on the outer side of the conveying belt 53 will roll at different parts of the foot along with the movement of the conveying belt 53, and through extruding and kneading the acupoints and muscles of the foot, the artificial massage method is simulated to stimulate the foot, promote the blood circulation of the foot, help relax the muscles, relieve the discomfort symptoms such as fatigue and soreness, and then promote the metabolism and health of the foot.

[0038] During the movement of the conveying belt 53, the plurality of stabilizing wheels 72 rotatably connected to the fixed plate 71 are in sliding contact with the inner side of the conveying belt 53, and they assist in supporting the conveying belt 53 and sharing part of the bearing pressure of the transmission roller 55, so as to ensure that the massage roller 54 can massage the foot along a stable and appropriate track, and improve the stability and comfort of the massage.

[0039] When the shell 51 has a tendency to change position under the action of external force, the sliding block 83 will move, and the elastic force of the compression spring 82 pushes the sliding block 83 to drive the shell 51 back to a relatively appropriate working position, so as to ensure that the massage mechanism is always in a relatively accurate position during the whole massage process, so that the massage can continuously and effectively act on the foot, and the accuracy and effectiveness of the massage are improved.

[0040] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
