[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-5As shown, a leg massager includes a housing 1, a support plate 2, and a driving device. The longitudinal section of the upper end of the housing 1 is inverted V-shaped with a smooth transition at the tip. A mounting cavity 11 is provided inside the housing 1. A thigh support surface 13 adapted to the contour of the posterior thigh is provided on the front side wall of the housing 1, and a thigh massage element 6 is provided at the thigh support surface 13. A swing opening 14 connecting to the mounting cavity 11 is provided on the rear side wall of the housing 1. The support plate 2 is movably disposed within the swing opening 14. The upper end of the support plate 2 is hinged to the housing 1, and its rotation axis is perpendicular to the opening direction of the swing opening 14. A calf support surface 21 adapted to the contour of the posterior calf is provided on the outer side wall of the support plate 2, and a calf massage element 7 is provided at the calf support surface 21. The driving device is disposed within the mounting cavity 11. In use, the leg massager is first laid flat. On a bed, mat, or carpet, or other furniture suitable for lying down, the user lies down and places their legs on the upper part of the housing 1, with the back of their thighs against the thigh support surface 13 and the back of their calves against the calf support surface 21. At this time, the thigh massager 6 can massage the back of the user's thighs, and the calf massager 7 can massage the back of the user's calves. The drive device can drive the support plate 2 to swing upward around the hinge end to disengage from the swing opening 14 or swing downward back into the swing opening 14, thereby causing the user's calves to swing. This allows the user's leg joints to be activated and unblocked while massaging the legs. This not only prevents the joints from becoming stiff due to lack of activity for a long time, but also allows the leg muscles to be repeatedly stretched, further relaxing the leg muscles and enhancing the massage experience.

[0029] Specifically, a handle 16 is provided on one side of the casing so that users can pick up the leg massager by the handle 16 for easy movement.

[0030] In one embodiment, both the thigh massager 6 and the calf massager 7 consist of several vibrating massage heads. The vibrating massage heads are connected to an external power source via wires. The several vibrating massage heads are evenly distributed on the corresponding thigh support surface 13 or calf support surface 21 (not shown in the attached figures) to relax the muscles on the back of the thigh and the back of the calf through vibration, promote lactic acid elimination, and relieve muscle soreness. The vibrating massage heads can be purchased through market channels and are not described in this embodiment.

[0031] Furthermore, a U-shaped arm 22 is connected to the inner side of the upper end of the tray 2. A pivot 23 is provided at the end of the U-shaped arm 22 away from the tray 2. The two ends of the pivot 23 are rotatably connected to two inner walls of the mounting cavity 11, so that the upper end of the tray 2 is spaced from its axis of rotation. This allows the upper end of the tray 2 to also be raised and moved away from the swing opening 14 when the tray 2 swings through the U-shaped arm 22. This makes the swing of the tray 2 more in line with the natural swing of the lower leg, ensuring that the tray 2 stays in contact with the lower leg, stably supporting the lower leg, and improving the swinging experience.

[0032] Furthermore, the driving device includes an air-blowing assembly 3 and an airbag 4. The bottom end of the airbag 4 is fixedly connected to the inner wall of the mounting cavity 11, and the top end of the airbag 4 is fixedly connected to the inner side wall of the support plate 2 at a position off the axis of rotation. The air-blowing assembly 3 is used to drive the airbag 4 to expand or contract, thereby using the expansion of the airbag 4 to push the support plate 2 to swing upward through the U-shaped arm 22. When the airbag 4 contracts, the support plate 2 will swing downward synchronously to reset under its own weight or the squeezing of the lower leg. This cycle can drive the lower leg to swing up and down repeatedly.

[0033] Furthermore, the inflation assembly 3 includes an air pump 31, a solenoid valve 32, and a main board 33. The air pump 31, solenoid valve 32, and main board 33 are all fixedly mounted on the inner wall of the mounting cavity 11. The air outlet of the air pump 31 is connected to the air inlet of the airbag 4 through the solenoid valve 32 and an air pipe. The air pump 31 and the solenoid valve 32 are electrically connected to the main board 33. The main board 33 can control the operation of the solenoid valve 32 and the air pump 31. When the airbag 4 needs to be inflated, the solenoid valve 32 connects the air outlet of the air pump 31 and the air inlet of the airbag 4, and the air pump 31 can supply air into the airbag 4. When the airbag 4 needs to be deflated, the solenoid valve 32 connects the air outlet of the airbag 4 to the outside, and the air inside the airbag 4 is discharged through the solenoid valve 32. This is prior art and will not be described in this embodiment.

[0034] Furthermore, the mounting cavity 11 is provided with a mounting seat 15, which is located below the support plate 2. The airbag 4 is set on the side of the mounting seat 15 facing the support plate 2. The bottom end of the airbag 4 is fixedly connected to the mounting seat 15, and the top end of the airbag 4 is fixedly connected to the inner wall of the support plate 2, so that the airbag 4 is set close to the support plate 2 to reduce the volume of the airbag 4. At the same time, the mounting seat 15 supports the airbag 4, thereby improving the transmission reliability of the airbag 4.

[0035] Furthermore, a top block 51 is fixedly provided at the top of the airbag 4. The end of the top block 51 away from the airbag 4 is fixedly connected to the inner wall of the support plate 2, so that the top block 51 replaces the connection between the airbag 4 and the inner wall of the support plate 2, thereby reducing the contact surface of the airbag 4, reducing the wear of the airbag 4, and extending the service life of the airbag 4.

[0036] Furthermore, a retaining shaft 52 is provided on the side of the top block 51 away from the airbag 4, and a retaining block 53 is provided at the end of the retaining shaft 52 away from the top block 51. The diameter of the retaining block 53 is larger than the diameter of the retaining shaft 52. A retaining cavity 24 is provided in the middle of the support plate 2. An avoidance hole 25 and a retaining hole 26 that connect to the retaining cavity 24 are provided on the inner wall of the support plate 2. A notch 27 that connects to the retaining hole 26 is provided on one side of the inner wall of the avoidance hole 25. The diameter of the avoidance hole 25 is greater than or equal to the diameter of the retaining block 53, and the diameter of the retaining hole 26 is smaller than the diameter of the retaining block 53. The retaining shaft 52 can extend into the avoidance hole 25 and be engaged in the retaining hole 26 through the notch 27.

[0037] In one embodiment, the support plate 2 is made of a plastic material with a certain degree of elasticity. The diameter of the retaining shaft 52 is larger than the width of the notch 27. When assembling the leg massager, the retaining block 53 can be passed through the clearance hole 25 first, so that the retaining shaft 52 extends into the clearance hole 25. Then, the retaining shaft 52 is moved so that it presses against the two side walls of the notch 27, causing the notch 27 to deform and expand until the retaining shaft 52 passes through and is fitted into the retaining hole 26. At this time, the notch 27 resets and retracts. The retaining block 53 and the notch 27 will restrict the retaining shaft 52 from disengaging from the retaining hole 26, thereby fixing the connection between the top block 51 and the support plate 2 (not shown in the attached figure).

[0038] Furthermore, the cross-section of the retaining shaft 52 is elongated, and the length of its short axis is less than or equal to the width of the notch 27, while the length of its long axis is greater than the width of the notch 27 and less than or equal to the diameter of the retaining hole 26.

[0039] In this embodiment, during installation, the locking block 53 is first passed through the clearance hole 25, so that the locking shaft 52 extends into the clearance hole 25. Then, the locking shaft 52 is rotated so that its narrow end aligns with the notch 27 and moves into the locking hole 26, so that the locking shaft 52 passes through the notch 27 and is locked in the locking hole 26. Then, the rotating shaft 23 is rotated again so that its narrow end is offset from the notch 27. At this time, since the wide end of the locking shaft 52 cannot pass through the notch 27 and the locking block 53 cannot pass through the locking hole 26, the locking shaft 52 cannot be disengaged from the locking hole 26, thereby fixing the connection between the top block 51 and the support plate 2.

[0040] Furthermore, the upper end of the housing 1 is provided with a support position 12, which is continuously arranged along its front side wall, upper side wall and rear side wall. The support position 12 is a concave arc surface. The thigh support surface 13 is provided at a position of the support position 12 on the front side wall of the housing 1, and the swing opening 14 is provided at a position of the support position 12 on the rear side wall of the housing 1.

[0041] In this embodiment, there are two support positions 12, two thigh massagers 6, and two calf massagers 7. The two support positions 12 are symmetrically arranged at both ends of the housing 1. The thigh massagers 6 and calf massagers 7 are arranged one-to-one with the support positions 12. The user can place his / her legs on the support positions 12, so that the back of his / her thigh is in contact with the thigh support surface 13 and the back of his / her calf is in contact with the calf support surface 21. At this time, the angle between the thigh and the calf is less than 180 degrees, so that the legs are kept bent and the muscles are kept relaxed. The leg massager can massage both of the user's legs at the same time, improving the massage efficiency and massage experience.

[0042] Furthermore, the thigh massager 6 includes a thigh electrode sheet 61 and a skin-friendly thigh conductive sheet 62. The thigh electrode sheet 61 is laid on the thigh support surface 13, and the thigh conductive sheet 62 covers the thigh electrode sheet 61 and is fixedly connected to the housing 1. The thigh electrode sheet 61 and the thigh conductive sheet 62 abut against each other. The calf massager 7 includes a calf electrode sheet 71 and a skin-friendly calf conductive sheet 72. The calf electrode sheet 71 is laid on the calf support surface 21, and the calf conductive sheet 72 covers the calf electrode sheet 71 and is fixedly connected to the support plate 2. The calf electrode sheet 71 and the calf conductive sheet 72 abut against each other.

[0043] Specifically, both the thigh electrode 61 and the calf electrode 71 are electrically connected to the main board 33. Taking the thigh electrode 61 as an example, it includes a positive electrode and a negative electrode. When the user's thigh is in contact with the thigh conductive pad 62, under power, the main board 33 will control the current to flow sequentially through the positive electrode, the thigh conductive pad 62 corresponding to the positive electrode, the posterior thigh muscle, the thigh conductive pad 62 corresponding to the negative electrode, and the negative electrode. This uses the current to stimulate the user's thigh muscles, improve blood circulation, and relieve muscle pain. The thigh conductive pad 62 can not only replace the thigh electrode 61 to conduct electricity to the user's massage area, but also protect the thigh electrode 61 and prevent it from being directly exposed, which would affect its service life. At the same time, both the thigh conductive pad 62 and the calf conductive pad 72 are made of soft and comfortable conductive silicone material. They replace the thigh electrode 61 to make direct contact with the human body, which can improve the user's massage comfort. The same applies to the calf electrode pad 71.

[0044] In this embodiment, the calf electrode 71 has a heating function so that it can apply heat to the calf muscles while performing electrotherapy, thereby further enhancing the massage effect. The electrode with the heating function can be purchased through market channels and will not be described in this embodiment.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
