[Modes for carrying out the invention]

[0006] In the following, in order to fully understand the purpose, features, and effects of this utility model, the concept, specific structure, and the resulting technical effects will be clearly and completely explained, along with the embodiments and accompanying drawings. Naturally, the embodiments described are only a part of, not all, embodiments of this utility model, and other embodiments that a person skilled in the art could obtain without creative effort based on the embodiments of this utility model are also within the scope of protection of this utility model. Furthermore, all connection / connection relationships relating to this patent do not mean only the direct connection of members, but rather that, depending on the specific embodiment, a superior connection structure can be constructed by adding or removing connecting accessories. The various technical features in this utility model creation can be combined interactively without contradicting or conflicting with each other.

[0007] Example 1 Referring to Figures 1 to 5, this embodiment provides a foot treatment device, which includes a treatment device comprising a foot pedal 1 and a projection 2. The projection 2 is connected to the bottom surface of the foot pedal 1, and the projection 2 is provided with a downward convex surface 20 for rolling on a plane. The foot pedal is oscillating around the line where the downward convex surface 20 and the plane are in contact as the axis of rotation. A control circuit is provided inside the treatment device, which is electrically connected to the foot pedal 1. The foot pedal 1 is provided with a conductive upper surface 11, and the control circuit is used to generate pulsed electrical stimulation signals for the foot pedal 1. When a user places their foot on the foot pedal 1, the control circuit alternately generates pulsed electrical stimulation signals of different frequencies to stimulate the nerves in the foot, alternately inducing contraction and expansion movements of the lower leg muscles of the foot, and the foot pedal 1 moves in conjunction with the movement of the foot so that the angle of the foot alternately changes around the ankle joint.

[0008] Preferably, the upper surface of the foot pedal 1 is provided with at least one foot massage foot pad 12 that is electrically connected to a control circuit for performing electrical stimulation massage.

[0009] In one embodiment of this system, the foot massage foot pad 12 is locked to the foot pedal 1 with screws or pins. Two foot massage foot pads 12 are provided, and the two foot massage foot pads 12 correspond to the soles of the user's two feet and are used to electrically stimulate and massage the soles of the user's feet.

[0010] Preferably, a mounting groove 13 is provided in the center of the foot pedal 1. The mounting groove 13 is for fixing the controller 14, and the controller 14 and the control circuit are connected wirelessly. The controller 14 can be used independently of the foot pedal 1. The user can turn on the corresponding function through the controller 14, causing the control circuit to alternately generate pulsed electrical signals of different low frequencies to stimulate the nerves in the foot.

[0011] Note that the design principles of the controller 14 and the control circuit are well-known knowledge to those skilled in the art, and will not be described in detail here.

[0012] In this embodiment, the foot pedal is provided with a first end 15 and a second end 16 for restricting the swing angle of the foot pedal, and the protrusion 2 is provided between the first end 15 and the second end 16.

[0013] Preferably, the ratio of the vertical height of the lower convex surface to the distance between the first end and the second end is 1:12 to 1:18. Specifically, the protrusion 2 extends from the first end 15 to the second end 16 and covers the entire lower surface of the foot pedal 1. This embodiment shows three embodiments of the lower convex surface 20.

[0014] Referring to FIGS. 1 to 3, in the first embodiment, the cross-section of the lower convex surface 20 is a rectangular shape with one top chamfered. Specifically, the lower convex surface 20 includes a first inclined surface 21, an arc surface 22, and a second inclined surface 23 that are connected in sequence. The angle formed by the first inclined surface 21 and the arc surface 22 is an obtuse angle, the angle formed by the arc surface 22 and the second inclined surface 23 is an obtuse angle, and the arc surface 22 is for smoothly transitioning the first inclined surface 21 and the second inclined surface 23.

[0015] Referring to FIG. 4, in the second embodiment, the cross-section of the lower convex surface 20 is a large arc. Note that the cross-section of the lower convex surface 20 is perpendicular to the line where the lower convex surface 20 contacts the plane.

[0016] Referring to FIG. 5, in the third embodiment, the cross-section of the lower convex surface 20 is an irregular curve, for example, a quadratic curve.

[0017] As described above, three embodiments of the lower convex surface 20 have been shown. In fact, the present invention does not limit the specific shape of the lower convex surface 20, and any lower convex shape with a high middle and low ends is acceptable.

[0018] Preferably, the foot treatment device further includes a support leg 3 located below the first end 15 and the second end 16.

[0019] In this embodiment, the support legs 3 are provided on the first inclined surface 21 and the second inclined surface 23.

[0020] By providing the support legs 3, they act as a buffer, reducing the wear that the foot pedal 1 experiences during oscillation and extending the lifespan of the foot pedal 1.

[0021] Preferably, the support legs 3 are made of an elastic material to have a better cushioning and protective effect.

[0022] Preferably, a fixing plate 4 is further provided on the lower convex surface 20. The fixing plate 4 has a free end 41 and a movable end 42. The movable end 42 is hinged to the side of the lower convex surface 20 closer to the first end 15, or the movable end 42 is hinged to the side of the lower convex surface 20 closer to the second end 16, and the free end 41 is rotatable relative to the movable end 42.

[0023] To make it easier to understand, when the fixing plate 4 is rotated to the side that attaches to the lower convex surface 20 and the plantar treatment device is placed on a flat surface, the foot pedal 1 can swing. When the fixing plate 4 rotates to open and the plantar treatment device is placed on a flat surface, the free end 41 of the fixing plate 4 is supported by the flat surface, and the foot pedal 1 can no longer swing.

[0024] During plantar therapy, the user places the sole of their foot on the surface of the foot pedal 1, and the control circuit alternately generates pulsed electrical stimulation signals of different frequencies. The conductive upper surface 11 of the foot pedal 1 induces alternating contraction and expansion movements in the muscles of the user's foot and lower leg, and the foot simultaneously oscillates around the lower convex surface 20 of the foot pedal 1, allowing the foot to undergo alternating angular changes around the ankle joint.

[0025] Compared to conventional foot treatment devices, the foot treatment device provided in this invention can effectively improve blood circulation during treatment of the lower limbs by oscillating the ankle joint. Furthermore, the structure of the foot treatment device is simple and easy to implement, which can effectively reduce production process costs and makes it suitable for mass production.

[0026] Example 2 Referring to Figures 6 to 8, this embodiment is almost the same as Embodiment 1, except that the projection 2 extends from a point near the first end 15 to a point near the second end 16, covering only the middle portion of the lower surface of the foot pedal 1.

[0027] Since the other features and effects of this embodiment are the same as those of Example 1, a detailed explanation thereof will be omitted. Those skilled in the art will understand that, under the teaching of the above embodiments, various embodiments in each of the above embodiments can be combined to obtain technical solutions of multiple embodiments. The foregoing is merely a better embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the utility model shall be included within the scope of protection of the utility model.
