DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-7 As shown, an embodiment of the present invention provides a lower limb massager, comprising a calf iron frame 1, a first airbag 2, an air pump, a first swing rod 3, a massage wheel 4, a rotating shaft 5 and a first compression spring 6; the first swing rod 3 is connected to the rotating shaft 5 through a one-way bearing 7, and the massage wheel 4 is arranged on the rotating shaft 5; one side of the first airbag 2 is fixed to the calf iron frame 1, and the other side abuts against one side of the first swing rod 3; one end of the first compression spring 6 is fixed to the calf iron frame 1, and the other end abuts against the first swing rod 3 or the other side of the first airbag 2; the air pump inflates and deflates the first airbag 2 through an air valve;

[0019] The air pump first inflates the first airbag 2 through the air valve to push the first swing rod 3 to drive the rotating shaft 5 and the massage wheel 4 to realize axial rotation, and at the same time, the first swing rod 3 rotates to squeeze the first compression spring 6 in a compressed state; thereafter, the air pump deflates the first airbag 2 through the air valve, the first compression spring 6 rebounds to press the first swing rod 3 back, and the massage wheel 4 maintains the current state without rolling back, and the air pump repeatedly inflates and deflates the first airbag 2 to push the massage wheel 4 to realize foot or leg massage.

[0020] That is to say, the lower limb massager provided by the present invention uses an airbag as a driving source, and the inflation and deflation of the airbag pushes the top rocker rod to drive the massage wheel on the rotating shaft to rotate axially, so as to perform a rolling massage action on the user's calf or foot. The airbag drive ensures the massage strength of the massage wheel while making the massage feel softer, providing softer massage techniques to meet the needs of different consumers, thereby solving the problem that the existing lower limb massagers use motor drive, making the massage more mechanized and the body feel harder.

[0021] Further, in one example, Figure 6 As shown, it also includes a second airbag 21 and a second swing rod 31, the second airbag 31 is arranged on the same side as the first airbag 2, the second swing rod 31 is connected to the rotating shaft 5 through a one-way bearing 7, one side of the second airbag 21 is fixed to the calf iron frame 1, and the other side abuts against one side of the second swing rod 31, one end of the second compression spring 61 is fixed to the calf iron frame 1, and the other end abuts against the second swing rod 31 or the other side of the second airbag 21; the air pump inflates and deflates the second airbag 31 through the air valve;

[0022] When the air pump inflates the first airbag 2 through the air valve, pushes the first swing rod 3 to drive the rotating shaft 5 and the massage wheel 4 to achieve axial rotation, and at the same time, the first swing rod 3 rotates and squeezes the first compression spring 6 to be in a compressed state; when the air pump deflates the first airbag 2 through the air valve, the first compression spring 6 rebounds to press the first swing rod 3 back, and the massage wheel 4 maintains the current state without rolling back. At the same time as the first airbag 2 is deflated, the air pump inflates the second airbag 21 through the air valve to push the second swing rod 31 to drive the rotating shaft 5 and the massage wheel 4 to achieve axial rotation, and the second swing rod 31 rotates and squeezes the second compression spring 61 to be in a compressed state; when the air pump deflates the second airbag 21 through the air valve, the second compression spring 61 rebounds to press the second swing rod 31 back, and the air pump repeatedly inflates and deflates the first airbag 2 and the second airbag 21 through the air valve to push the massage wheel to achieve rolling massage of the soles of the feet or legs.

[0023] In this way, when the roller does not roll back when the first airbag is deflated, the second airbag can be inflated to push the second swing rod to drive the massage wheel on the rotating shaft to rotate, so that the massage wheel can continuously rotate to massage the user's legs or feet.

[0024] Among them, Figure 4 and 6 As shown, the first airbag and the second airbag are multi-layer airbags, which can increase the amplitude of the push-up swing rod and increase the massage intensity. In addition, the first airbag and the second airbag are flexible airbags, which can expand and deform when squeezed.

[0025] In one example, the massage wheel is connected to the rotating shaft through a gear set, and the gear set is a reduction gear set, so that the user can press the first airbag with a small force to make the first airbag deform greatly. For example, when the user's foot steps on the massage wheel, the user's foot presses the massage wheel with a small force, and the force of the massage wheel is transmitted to the first airbag through the reduction gear set, and the airbag is deformed greatly, so that the user's massage force is weakened, making the massage action on the foot softer.

[0026] In another example, the massage wheel is fixed on the rotating shaft, and the outer diameter of the massage wheel is larger than the outer diameter of the rotating shaft, so that the user can press the first airbag with a smaller force to cause a larger deformation of the first airbag.

[0027] Furthermore, in one example, an air pressure detector is provided in the first airbag, and the air pressure detector is connected to the air pump signal through a main control board. When the air pressure detector detects that the pressure in the first airbag is higher than a preset threshold, the main control board controls the air pump to slow down the inflation speed of the first airbag.

[0028] Similarly, the design of the second airbag is the same as that of the first airbag, and will not be described in detail in this embodiment.

[0029] Further, in one example, Figure 4 and 6 As shown, the lower limb massager also includes a first airbag support plate 8 and a second airbag support plate 9, the first airbag 2 is fixed on the first support plate 8, and the first airbag support plate 8 is fixed on the calf iron frame 1; the second airbag 21 is fixed on the second support plate 9, and the second airbag support plate 9 is fixed on the calf iron frame 1. Figure 4 and 6 As shown, the first airbag support plate 8 and the second airbag support plate 9 are arranged along a slope close to the rotation axis 5. In this way, the thrust of the first airbag and the second airbag on the first swing arm and the second swing arm after inflation can be stronger and more efficient.

[0030] Further, in one example, Figure 4 As shown, the first swing rod 3 and the first airbag 2 are against one side and are adapted to the inflation arc of the first airbag 2; the second swing rod 31 and the second airbag 21 are against one side and are adapted to the inflation arc of the second airbag 21. For example, the swing rod and the airbag can be in an S-shaped shape, so that the airbag fits better with the swing rod after inflation, the thrust is more concentrated and the strength is higher, so that the massage wheel has a stronger massage force and a better massage effect.

[0031] Further, in one example, in order to enrich the massage techniques of the lower limb massager, such as Figure 7 As shown, the lower limb massager may further include a massage plate 41, which is arranged on the rotating shaft through a conical gear 42, and the rotating shaft 5 rotates to drive the massage plate 41 to achieve end face rotation massage. The massage plate 41 is provided with convex points, so that the user's legs or feet can be rubbed and massaged. In this way, the driving power source of the air bag remains unchanged, and the conical gear installed on the rotating shaft changes to drive another conical gear, driving the rotating massage plate to achieve the effect of massaging the user's legs or feet.

[0032] Further, in one example, Figure 2 As shown, a positioning groove 32 is provided on the first rocker arm 3, and the one-way bearing 7 is tightly fitted into the positioning groove 32 and installed on the rotating shaft 5 to be radially limited by a retaining ring 33, and the one-way bearing 7 is limited in the positioning groove 32 by a limiting screw 34 to prevent it from falling out.

[0033] The specific structure of the lower limb massager of the present invention is described in detail below.

[0034] like Figure 1-7As shown, the lower limb massager of the embodiment of the present invention comprises a calf iron frame 1, a first air bag 2, an air pump, a first swing rod 3, a massage wheel 4, a rotating shaft 5 and a first compression spring 6. The air pump inflates and deflates the first air bag 2 through an air valve; the first swing rod 3 is connected to the rotating shaft 5 through a one-way bearing 7. Specifically, a positioning groove 32 is provided on the first swing rod 3. The one-way bearing 7 is tightly fitted into the positioning groove 32 and installed on the rotating shaft 5, and then radially limited by a retaining ring 33. The one-way bearing 7 is limited in the positioning groove 32 by a limiting screw 34 to prevent it from falling out, and then the massage wheel 4 is installed on the rotating shaft 5 and fixed to the rotating shaft 5 by an elastic pin 51; when the one-way bearing 7 rotates clockwise, it can drive the massage wheel 4 on the rotating shaft 5 to rotate to massage the user. When the one-way bearing 7 rotates counterclockwise, it is in a relaxed state and the massage wheel 4 does not roll back. The first airbag 2 is installed on the first airbag support plate 8, the first airbag support plate 8 is fixed on the calf iron frame 1, the first airbag support plate 8 is sloped along the direction of the rotating axis 5, the other side of the first airbag 2 is against the first swing arm 3, and the curvature of the first swing arm 3 is consistent with the curve of the first airbag 2 after inflation; the first compression spring 6 is similar to an L-shape, one end of the first compression spring 6 is fixed on the calf iron frame 1, and the other end is against the other side of the first swing arm 3.

[0035] During operation, the air pump inflates the first airbag through the air valve, pushes the first swing arm to drive the rotating shaft to rotate, and the one-way bearing is forced to turn, driving the massage wheel to rotate to massage the user. When the first airbag is inflated to a saturated state, the first compression spring is in a compressed state. When the first airbag is deflated, the first compression spring presses the first swing arm back, and the one-way bearing rotates counterclockwise to a relaxed state. The massage wheel maintains the current state and does not roll back. The first airbag is reciprocatedly inflated and deflated to push the massage wheel to roll to achieve leg massage.

[0036] Furthermore, by installing the mechanism on the other side with the same principle, when the first airbag is deflated, the second airbag is inflated to push the second rocker arm to rotate the rotating shaft, so that the massage wheel rotates to massage the user, thereby achieving continuous rolling massage of the user's legs or feet through the coordination of inflation and deflation of the first airbag and the second airbag.

[0037] It should be noted that the one-way steering rotation achieved by the one-way bearing may also be achieved by a ratchet, and the embodiment of the present invention does not impose any limitation on this.

[0038] That is to say, the lower limb massager provided by the present invention uses an airbag as a driving source, and the inflation and deflation of the airbag pushes the top rocker rod to drive the massage wheel on the rotating shaft to rotate axially, so as to perform a rolling massage action on the user's calf or foot. The airbag drive ensures the massage strength of the massage wheel while making the massage feel softer, providing softer massage techniques to meet the needs of different consumers, thereby solving the problem that the existing lower limb massagers use motor drive, making the massage more mechanized and the body feel harder.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
